One of V's goals is to be open to developers with different levels +of experience in compiler development. Compilers don't need to be black boxes +full of magic that only few people understand. + +The V compiler is modular, and can be used by other applications. It is located +in `cmd/v/` and `vlib/v/`. + +The most important and useful command to remember when working on the V compiler +is `v self`. +It rebuilds the V compiler. + +Be careful, if you introduce a breaking change and rebuild V, you will no longer +be able to use V to build itself. So it's a good idea to make a backup copy of a +working compiler executable. + +But don't worry, you can always simply run `make` (or `make.bat`), it will +download the C version of the compiler and rebuild it from scratch. + +The architecture of the compiler is very simple and has three distinct steps: + +Parse/generate AST (`v.parser`) => Check types (`v.checker`) +=> Generate C/JavaScript/machine code (`v.gen`) + + +The main files are: + +1. `cmd/v/v.v` The entry point. + +- V figures out the build mode. +- Constructs the compiler object (`struct V`). +- Creates a list of .v files that need to be parsed. +- Creates a parser object for each file and runs `parse()` on them. +- The correct backend is called (C, JS, native), and a binary is compiled. + +2. `v/scanner` The scanner's job is to parse a list of characters and convert +them to tokens. + +3. `v/token` This is simply a list of all tokens, their string values, and a +couple of helper functions. + +4. `v/parser` The parser. It converts a list of tokens into an AST. +In V, objects can be used before declaration, so unknown types are marked as +unresolved. They are resolved later in the type checker. + +5. `v/table` V creates one table object that is shared by all parsers. It +contains all types, consts, and functions, as well as several helpers to search +for objects by name, register new objects, modify types' fields, etc. + +6. `v/checker` Type checker and resolver. It processes the AST and makes sure +the types are correct. Unresolved types are resolved, type information is added +to the AST. + +7. `v/gen/c` C backend. It simply walks the AST and generates C code that can be +compiled with Clang, GCC, Visual Studio, and TCC. + +8. `json.v` defines the json code generation. This file will be removed once V +supports comptime code generation, and it will be possible to do this using the +language's tools. + +9. `v/gen/native` is the directory with all the machine code generation logic. It +defines a set of functions that translate assembly instructions to machine code +and build the binary from scratch byte by byte. It manually builds all headers, +segments, sections, symtable, relocations, etc. Right now it only has basic +support of the native platform (ELF, MACHO format). + +The rest of the directories are vlib modules: `builtin/` (strings, arrays, +maps), `time/`, `os/`, etc. Their documentation is pretty clear. + +## Example Workflow for Contributing +(provided by [@spytheman](https://github.com/spytheman)) + +(If you don't already have a GitHub account, please create one. Your GitHub +username will be referred to later as 'YOUR_GITHUB_USERNAME'. Change it +accordingly in the steps below.) + +1. Fork https://github.com/vlang/v using GitHub's interface to your own account. +Let's say that the forked repository is at +`https://github.com/YOUR_GITHUB_USERNAME/v` . +2. Clone the main v repository https://github.com/vlang/v to a local folder on +your computer, say named nv/ (`git clone https://github.com/vlang/v nv`) +3. `cd nv` +4. `git remote add pullrequest https://github.com/YOUR_GITHUB_USERNAME/v` +NB: the remote named `pullrequest` should point to YOUR own forked repo, not the +main v repository! After this, your local cloned repository is prepared for +making pullrequests, and you can just do normal git operations such as: +`git pull` `git status` and so on. + +5. When finished with a feature/bugfix/change, you can: +`git checkout -b fix_alabala` +6. `git push pullrequest` # (NOTE: the `pullrequest` remote was setup on step 4) +7. On GitHub's web interface, go to: https://github.com/vlang/v/pulls + + Here the UI shows a dialog with a button to make a new pull request based on + the new pushed branch. + (Example dialog: https://url4e.com/gyazo/images/364edc04.png) + +8. After making your pullrequest (aka, PR), you can continue to work on the +branch `fix_alabala` ... just do again `git push pullrequest` when you have more +commits. + +9. If there are merge conflicts, or a branch lags too much behind V's master, +you can do the following: + + 1. `git pull --rebase origin master` # solve conflicts and do + `git rebase --continue` + 2. `git push pullrequest -f` # this will overwrite your current remote branch + with the updated version of your changes. + +The point of doing the above steps, is to never directly push to the main V +repository, *only to your own fork*. Since your local `master` branch tracks the +main V repository's master, then `git checkout master`, as well as +`git pull --rebase origin master` will continue to work as expected +(these are actually used by `v up`) and git can always do it cleanly. + +Git is very flexible, so there are other ways to accomplish the same thing. +See the [GitHub flow](https://guides.github.com/introduction/git-handbook/#github), for more information. + +## Using Github's hub CLI tool + +You can download the `hub` tool from https://hub.github.com/ . Using +`hub`, you will not need to go through the (sometimes) slow website +to make PRs. Most remote operations can be done through the `hub` CLI +command. + +NB: You still need to have a GitHub account. + +### Preparation: +(steps 1..3 need to be done just *once*): + +1. `hub clone vlang/v my_v` +2. `cd my_v` +3. `hub fork --remote-name pullrequest` + +4. `git checkout -b my_cool_feature` # Step 4 is better done *once per each new +feature/bugfix* that you make. + +### Improve V by making commits: + +5. `git commit -am "math: add a new function copysign"` + +### Testing your commits locally: +You can test locally whether your changes have not broken something by +running: `v test-all`. See `TESTS.md` for more details. + +### Publishing your commits to GitHub: + +6. `git push pullrequest` + +### Making a PR with `hub`: +(so that your changes can be merged to the main V repository) + +7. `hub pull-request` + +Optionally, you can track the status of your PR CI tests with: + +8. `hub ci-status --verbose` + +### Fixing failing tests: +If everything is OK, after 5-10 minutes, the CI tests should pass for +all platforms. If not, visit the URLs for the failing CI jobs, see +which tests have failed and then fix them by making more changes. Just use +`git push pullrequest` to publish your changes. The CI tests will +run with your updated code. Use `hub ci-status --verbose` to monitor +their status. + +## Flags + +V allows you to pass custom flags using `-d my_flag` that can then be checked +at compile time (see the documentation about +[compile-time if](https://github.com/vlang/v/blob/master/doc/docs.md#compile-time-if)). +There are numerous flags that can be passed when building the compiler +with `v self` or when creating a copy of the compiler, that will help +you when debugging. + +Beware that the flags must be passed when building the compiler, +not the program, so do for example: `v -d time_parsing cmd/v` or +`v -d trace_checker self`. +Some flags can make the compiler very verbose, so it is recommended +to create a copy of the compiler rather than replacing it with `v self`. + +| Flag | Usage | +|------|-------| +| `debugautostr` | Prints informations about `.str()` method auto-generated by the compiler during C generation | +| `debugscanner` | Prints debug information during the scanning phase | +| `debug_codegen` | Prints automatically generated V code during the scanning phase | +| `debug_interface_table` | Prints generated interfaces during C generation | +| `debug_interface_type_implements` | Prints debug information when checking that a type implements in interface | +| `print_vweb_template_expansions` | Prints vweb compiled HTML files | +| `time_checking` | Prints the time spent checking files and other related informations | +| `time_parsing` | Prints the time spent parsing files and other related informations | +| `trace_ccoptions` | Prints options passed down to the C compiler | +| `trace_checker` | Prints informations about the statements being checked | +| `trace_gen` | Prints strings written to the generated C file.

+ +## Key Features of V + +- Simplicity: the language can be learned in less than an hour +- Fast compilation: ≈110k loc/s with a Clang backend, + ≈1 million loc/s with native and tcc backends *(Intel i5-7500, SSD, no optimization)* ([demo video](https://www.youtube.com/watch?v=pvP6wmcl_Sc)) +- Easy to develop: V compiles itself in less than a second +- Performance: as fast as C (V's main backend compiles to human readable C) +- Safety: no null, no globals, no undefined behavior, immutability by default +- C to V translation +- Hot code reloading +- [Innovative memory management](https://vlang.io/#memory) ([demo video](https://www.youtube.com/watch?v=gmB8ea8uLsM)) +- [Cross-platform UI library](https://github.com/vlang/ui) +- Built-in graphics library +- Easy cross compilation +- REPL +- [Built-in ORM](https://github.com/vlang/v/blob/master/doc/docs.md#orm) +- [Built-in web framework](https://github.com/vlang/v/blob/master/vlib/vweb/README.md) +- C and JavaScript backends +- Great for writing low level software ([Vinix OS](https://github.com/vlang/vinix)) + +## Stability guarantee and future changes + +Despite being at an early development stage, the V language is relatively stable and has +backwards compatibility guarantee, meaning that the code you write today is guaranteed +to work a month, a year, or five years from now. + +There still may be minor syntax changes before the 1.0 release, but they will be handled +automatically via `vfmt`, as has been done in the past. + +The V core APIs (primarily the `os` module) will still have minor changes until +they are stabilized in V 1.0. Of course the APIs will grow after that, but without breaking +existing code. + +Unlike many other languages, V is not going to be always changing, with new features +being introduced and old features modified. It is always going to be a small and simple +language, very similar to the way it is right now. + +## Installing V from source + +### Linux, macOS, Windows, *BSD, Solaris, WSL, Android, Raspbian + +```bash +git clone https://github.com/vlang/v +cd v +make +``` + +That's it! Now you have a V executable at `[path to V repo]/v`. +`[path to V repo]` can be anywhere. + +(On Windows `make` means running `make.bat`, so make sure you use `cmd.exe`) + +Now you can try `./v run examples/hello_world.v` (`v.exe` on Windows). + +V is constantly being updated. To update V, simply run: + +```bash +v up +``` + +### C compiler + +It's recommended to use Clang, GCC, or Visual Studio. +If you are doing development, you most likely already have one of those installed. + +Otherwise, follow these instructions: + +- [Installing a C compiler on Linux and macOS](https://github.com/vlang/v/wiki/Installing-a-C-compiler-on-Linux-and-macOS) + +- [Installing a C compiler on Windows](https://github.com/vlang/v/wiki/Installing-a-C-compiler-on-Windows) + +However, if none is found when running `make` on Linux or Windows, +TCC is downloaded as the default C backend. +It's very lightweight (several MB) so this shouldn't take too long. + +### Symlinking + +NB: it is *highly recommended*, that you put V on your PATH. That saves +you the effort to type in the full path to your v executable every time. +V provides a convenience `v symlink` command to do that more easily. + +On Unix systems, it creates a `/usr/local/bin/v` symlink to your +executable. To do that, run: + +```bash +sudo ./v symlink +``` + +On Windows, start a new shell with administrative privileges, for +example by Windows Key, then type `cmd.exe`, right click on its menu +entry, and choose `Run as administrator`. In the new administrative +shell, cd to the path, where you have compiled v.exe, then type: + +```bat +.\v.exe symlink +``` + +That will make V available everywhere, by adding it to your PATH. +Please restart your shell/editor after that, so that it can pick +the new PATH variable. + +NB: there is no need to run `v symlink` more than once - v will +continue to be available, even after `v up`, restarts and so on. +You only need to run it again, if you decide to move the V repo +folder somewhere else. + +### Docker + +

    + + + +## Hello World + + +```v +fn main() { + println('hello world') +} +``` + +Save this snippet into a file named `hello.v`. Now do: `v run hello.v`. + +> That is assuming you have symlinked your V with `v symlink`, as described +[here](https://github.com/vlang/v/blob/master/README.md#symlinking). +If you haven't yet, you have to type the path to V manually. + +Congratulations - you just wrote and executed your first V program! + +You can compile a program without execution with `v hello.v`. +See `v help` for all supported commands. + +From the example above, you can see that functions are declared with the `fn` keyword. +The return type is specified after the function name. +In this case `main` doesn't return anything, so there is no return type. + +As in many other languages (such as C, Go, and Rust), `main` is the entry point of your program. + +`println` is one of the few built-in functions. +It prints the value passed to it to standard output. + +`fn main()` declaration can be skipped in one file programs. +This is useful when writing small programs, "scripts", or just learning the language. +For brevity, `fn main()` will be skipped in this tutorial. + +This means that a "hello world" program in V is as simple as + +```v +println('hello world') +``` + +## Running a project folder with several files + +Suppose you have a folder with several .v files in it, where one of them +contains your `main()` function, and the other files have other helper +functions. They may be organized by topic, but still *not yet* structured +enough to be their own separate reusable modules, and you want to compile +them all into one program. + +In other languages, you would have to use includes or a build system +to enumerate all files, compile them separately to object files, +then link them into one final executable. + +In V however, you can compile and run the whole folder of .v files together, +using just `v run .`. Passing parameters also works, so you can +do: `v run . --yourparam some_other_stuff` + +The above will first compile your files into a single program (named +after your folder/project), and then it will execute the program with +`--yourparam some_other_stuff` passed to it as CLI parameters. + +Your program can then use the CLI parameters like this: +```v +import os + +println(os.args) +``` +NB: after a successful run, V will delete the generated executable. +If you want to keep it, use `v -keepc run .` instead, or just compile +manually with `v .` . + +NB: any V compiler flags should be passed *before* the `run` command. +Everything after the source file/folder, will be passed to the program +as is - it will not be processed by V. + +## Comments + +```v +// This is a single line comment. +/* +This is a multiline comment. + /* It can be nested. */ +*/ +``` + +## Functions + +```v +fn main() { + println(add(77, 33)) + println(sub(100, 50)) +} + +fn add(x int, y int) int { + return x + y +} + +fn sub(x int, y int) int { + return x - y +} +``` + +Again, the type comes after the argument's name. + +Just like in Go and C, functions cannot be overloaded. +This simplifies the code and improves maintainability and readability. + +Functions can be used before their declaration: +`add` and `sub` are declared after `main`, but can still be called from `main`. +This is true for all declarations in V and eliminates the need for header files +or thinking about the order of files and declarations. + +### Returning multiple values + +```v +fn foo() (int, int) { + return 2, 3 +} + +a, b := foo() +println(a) // 2 +println(b) // 3 +c, _ := foo() // ignore values using `_` +``` + +## Symbol visibility + +```v +pub fn public_function() { +} + +fn private_function() { +} +``` + +Functions are private (not exported) by default. +To allow other modules to use them, prepend `pub`. The same applies +to constants and types. + +Note: `pub` can only be used from a named module. +For information about creating a module, see [Modules](#modules). + +## Variables + +```v +name := 'Bob' +age := 20 +large_number := i64(9999999999) +println(name) +println(age) +println(large_number) +``` + +Variables are declared and initialized with `:=`. This is the only +way to declare variables in V. This means that variables always have an initial +value. + +The variable's type is inferred from the value on the right hand side. +To choose a different type, use type conversion: +the expression `T(v)` converts the value `v` to the +type `T`. + +Unlike most other languages, V only allows defining variables in functions. +Global (module level) variables are not allowed. There's no global state in V +(see [Pure functions by default](#pure-functions-by-default) for details). + +For consistency across different code bases, all variable and function names +must use the `snake_case` style, as opposed to type names, which must use `PascalCase`. + +### Mutable variables + +```v +mut age := 20 +println(age) +age = 21 +println(age) +``` + +To change the value of the variable use `=`. In V, variables are +immutable by default. +To be able to change the value of the variable, you have to declare it with `mut`. + +Try compiling the program above after removing `mut` from the first line. + +### Initialization vs assignment + +Note the (important) difference between `:=` and `=`. +`:=` is used for declaring and initializing, `=` is used for assigning. + +```v failcompile +fn main() { + age = 21 +} +``` + +This code will not compile, because the variable `age` is not declared. +All variables need to be declared in V. + +```v +fn main() { + age := 21 +} +``` + +The values of multiple variables can be changed in one line. +In this way, their values can be swapped without an intermediary variable. + +```v +mut a := 0 +mut b := 1 +println('$a, $b') // 0, 1 +a, b = b, a +println('$a, $b') // 1, 0 +``` + +### Declaration errors + +In development mode the compiler will warn you that you haven't used the variable +(you'll get an "unused variable" warning). +In production mode (enabled by passing the `-prod` flag to v – `v -prod foo.v`) +it will not compile at all (like in Go). + +```v failcompile nofmt +fn main() { + a := 10 + if true { + a := 20 // error: redefinition of `a` + } + // warning: unused variable `a` +} +``` + +Unlike most languages, variable shadowing is not allowed. Declaring a variable with a name +that is already used in a parent scope will cause a compilation error. + +You can shadow imported modules though, as it is very useful in some situations: +```v ignore +import ui +import gg + +fn draw(ctx &gg.Context) { + gg := ctx.parent.get_ui().gg + gg.draw_rect(10, 10, 100, 50) +} +``` + +## V Types + +### Primitive types + +```v ignore +bool + +string + +i8 i16 int i64 i128 (soon) +byte u16 u32 u64 u128 (soon) + +rune // represents a Unicode code point + +f32 f64 + +voidptr, size_t // these are mostly used for C interoperability + +any // similar to C's void* and Go's interface{} +``` + +Please note that unlike C and Go, `int` is always a 32 bit integer. + +There is an exception to the rule that all operators +in V must have values of the same type on both sides. A small primitive type +on one side can be automatically promoted if it fits +completely into the data range of the type on the other side. +These are the allowed possibilities: + +```v ignore + i8 → i16 → int → i64 + ↘ ↘ + f32 → f64 + ↗ ↗ + byte → u16 → u32 → u64 ⬎ + ↘ ↘ ↘ ptr + i8 → i16 → int → i64 ⬏ +``` +An `int` value for example can be automatically promoted to `f64` +or `i64` but not to `u32`. (`u32` would mean loss of the sign for +negative values). +Promotion from `int` to `f32`, however, is currently done automatically +(but can lead to precision loss for large values). + +Literals like `123` or `4.56` are treated in a special way. They do +not lead to type promotions, however they default to `int` and `f64` +respectively, when their type has to be decided: + +```v nofmt +u := u16(12) +v := 13 + u // v is of type `u16` - no promotion +x := f32(45.6) +y := x + 3.14 // x is of type `f32` - no promotion +a := 75 // a is of type `int` - default for int literal +b := 14.7 // b is of type `f64` - default for float literal +c := u + a // c is of type `int` - automatic promotion of `u`'s value +d := b + x // d is of type `f64` - automatic promotion of `x`'s value +``` + +### Strings + +```v +name := 'Bob' +println(name.len) +println(name[0]) // indexing gives a byte B +println(name[1..3]) // slicing gives a string 'ob' +windows_newline := '\r\n' // escape special characters like in C +assert windows_newline.len == 2 +``` + +In V, a string is a read-only array of bytes. String data is encoded using UTF-8. +String values are immutable. You cannot mutate elements: + +```v failcompile +mut s := 'hello 🌎' +s[0] = `H` // not allowed +``` +> error: cannot assign to `s[i]` since V strings are immutable + +Note that indexing a string will produce a `byte`, not a `rune` nor another `string`. +Indexes correspond to bytes in the string, not Unicode code points. If you want to +convert the `byte` to a `string`, use the `ascii_str()` method: + +```v +country := 'Netherlands' +println(country[0]) // Output: 78 +println(country[0].ascii_str()) // Output: N +``` + +Character literals have type `rune`. To denote them, use ` + +```v +rocket := `🚀` +assert 'aloha!'[0] == `a` +``` + +Both single and double quotes can be used to denote strings. For consistency, +`vfmt` converts double quotes to single quotes unless the string contains a single quote character. + +For raw strings, prepend `r`. Raw strings are not escaped: + +```v +s := r'hello\nworld' +println(s) // "hello\nworld" +``` + +Strings can be easily converted to integers: + +```v +s := '42' +n := s.int() // 42 +``` + +### Runes +A `rune` represents a unicode character and is an alias for `u32`. Runes can be created like this: +```v +x := `🚀` +``` + +A string can be converted to runes by the `.runes()` method. +```v +hello := 'Hello World 👋' +hello_runes := hello.runes() // [`H`, `e`, `l`, `l`, `o`, ` `, `W`, `o`, `r`, `l`, `d`, ` `, `👋`] +``` + +### String interpolation + +Basic interpolation syntax is pretty simple - use `$` before a variable name. +The variable will be converted to a string and embedded into the literal: +```v +name := 'Bob' +println('Hello, $name!') // Hello, Bob! +``` +It also works with fields: `'age = $user.age'`. +If you need more complex expressions, use `${}`: `'can register = ${user.age > 13}'`. + +Format specifiers similar to those in C's `printf()` are also supported. +`f`, `g`, `x`, etc. are optional and specify the output format. +The compiler takes care of the storage size, so there is no `hd` or `llu`. + +```v +x := 123.4567 +println('x = ${x:4.2f}') +println('[${x:10}]') // pad with spaces on the left => [ 123.457] +println('[${int(x):-10}]') // pad with spaces on the right => [123 ] +println('[${int(x):010}]') // pad with zeros on the left => [0000000123] +``` + +### String operators + +```v +name := 'Bob' +bobby := name + 'by' // + is used to concatenate strings +println(bobby) // "Bobby" +mut s := 'hello ' +s += 'world' // `+=` is used to append to a string +println(s) // "hello world" +``` + +All operators in V must have values of the same type on both sides. +You cannot concatenate an integer to a string: + +```v failcompile +age := 10 +println('age = ' + age) // not allowed +``` +> error: infix expr: cannot use `int` (right expression) as `string` + +We have to either convert `age` to a `string`: + +```v +age := 11 +println('age = ' + age.str()) +``` + +or use string interpolation (preferred): + +```v +age := 12 +println('age = $age') +``` + +### Numbers + +```v +a := 123 +``` + +This will assign the value of 123 to `a`. By default `a` will have the +type `int`. + +You can also use hexadecimal, binary or octal notation for integer literals: + +```v +a := 0x7B +b := 0b01111011 +c := 0o173 +``` + +All of these will be assigned the same value, 123. They will all have type +`int`, no matter what notation you used. + +V also supports writing numbers with `_` as separator: + +```v +num := 1_000_000 // same as 1000000 +three := 0b0_11 // same as 0b11 +float_num := 3_122.55 // same as 3122.55 +hexa := 0xF_F // same as 255 +oct := 0o17_3 // same as 0o173 +``` + +If you want a different type of integer, you can use casting: + +```v +a := i64(123) +b := byte(42) +c := i16(12345) +``` + +Assigning floating point numbers works the same way: + +```v +f := 1.0 +f1 := f64(3.14) +f2 := f32(3.14) +``` +If you do not specify the type explicitly, by default float literals +will have the type of `f64`. + +Float literals can also be declared as a power of ten: +```v +f0 := 42e1 // 420 +f1 := 123e-2 // 1.23 +f2 := 456e+2 // 45600 +``` + +### Arrays +#### Basic Array Concepts +Arrays are collections of data elements of the same type. They can be represented by +a list of elements surrounded by brackets. The elements can be accessed by appending +an *index* (starting with `0`) in brackets to the array variable: +```v +mut nums := [1, 2, 3] +println(nums) // `[1, 2, 3]` +println(nums[0]) // `1` +println(nums[1]) // `2` +nums[1] = 5 +println(nums) // `[1, 5, 3]` +``` +#### Array Properties +There are two properties that control the "size" of an array: +* `len`: *length* - the number of pre-allocated and initialized elements in the array +* `cap`: *capacity* - the amount of memory space which has been reserved for elements, +but not initialized or counted as elements. The array can grow up to this size without +being reallocated. Usually, V takes care of this property automatically but there are +cases where the user may want to do manual optimizations (see [below](#array-initialization)). + +```v +mut nums := [1, 2, 3] +println(nums.len) // "3" +println(nums.cap) // "3" or greater +nums = [] // The array is now empty +println(nums.len) // "0" +``` + +Note that the properties are read-only fields and can't be modified by the user. + +#### Array Initialization +The basic initialization syntax is as described [above](#basic-array-concepts). +The type of an array is determined by the first element: +* `[1, 2, 3]` is an array of ints (`[]int`). +* `['a', 'b']` is an array of strings (`[]string`). + +The user can explicitly specify the type for the first element: `[byte(16), 32, 64, 128]`. +V arrays are homogeneous (all elements must have the same type). +This means that code like `[1, 'a']` will not compile. + +The above syntax is fine for a small number of known elements but for very large or empty +arrays there is a second initialization syntax: +```v +mut a := []int{len: 10000, cap: 30000, init: 3} +``` +This creates an array of 10000 `int` elements that are all initialized with `3`. Memory +space is reserved for 30000 elements. The parameters `len`, `cap` and `init` are optional; +`len` defaults to `0` and `init` to the default initialization of the element type (`0` +for numerical type, `''` for `string`, etc). The run time system makes sure that the +capacity is not smaller than `len` (even if a smaller value is specified explicitly): + +```v +arr := []int{len: 5, init: -1} +// `arr == [-1, -1, -1, -1, -1]`, arr.cap == 5 + +// Declare an empty array: +users := []int{} +``` + + +Setting the capacity improves performance of pushing elements to the array +as reallocations can be avoided: + +```v +mut numbers := []int{cap: 1000} +println(numbers.len) // 0 +// Now appending elements won't reallocate +for i in 0 .. 1000 { + numbers << i +} +``` +Note: The above code uses a [range `for`](#range-for) statement and a +[push operator (`<<`)](#array-operations). + +#### Array Types + +An array can be of these types: +| Types | Example Definition | +| ------------ | ------------------------------------ | +| Number | `[]int,[]i64` | +| String | `[]string` | +| Rune | `[]rune` | +| Boolean | `[]bool` | +| Array | `[][]int` | +| Struct | `[]MyStructName` | +| Channel | `[]chan f64` | +| Function | `[]MyFunctionType` `[]fn (int) bool` | +| Interface | `[]MyInterfaceName` | +| Sum Type | `[]MySumTypeName` | +| Generic Type | `[]T` | +| Map | `[]map[string]f64` | +| Enum | `[]MyEnumType` | +| Alias | `[]MyAliasTypeName` | +| Thread | `[]thread int` | +| Reference | `[]&f64` | +| Shared | `[]shared MyStructType` | + +**Example Code:** + +This example uses [Structs](#structs) and [Sum Types](#sum-types) to create an array +which can handle different types (e.g. Points, Lines) of data elements. + +```v +struct Point { + x int + y int +} + +struct Line { + p1 Point + p2 Point +} + +type ObjectSumType = Line | Point + +mut object_list := []ObjectSumType{} +object_list << Point{1, 1} +object_list << Line{ + p1: Point{3, 3} + p2: Point{4, 4} +} +dump(object_list) +/* +object_list: [ObjectSumType(Point{ + x: 1 + y: 1 +}), ObjectSumType(Line{ + p1: Point{ + x: 3 + y: 3 + } + p2: Point{ + x: 4 + y: 4 + } +})] +*/ +``` + +#### Multidimensional Arrays + +Arrays can have more than one dimension. + +2d array example: +```v +mut a := [][]int{len: 2, init: []int{len: 3}} +a[0][1] = 2 +println(a) // [[0, 2, 0], [0, 0, 0]] +``` + +3d array example: +```v +mut a := [][][]int{len: 2, init: [][]int{len: 3, init: []int{len: 2}}} +a[0][1][1] = 2 +println(a) // [[[0, 0], [0, 2], [0, 0]], [[0, 0], [0, 0], [0, 0]]] +``` + +#### Array Operations + +Elements can be appended to the end of an array using the push operator `<<`. +It can also append an entire array. + +```v +mut nums := [1, 2, 3] +nums << 4 +println(nums) // "[1, 2, 3, 4]" +// append array +nums << [5, 6, 7] +println(nums) // "[1, 2, 3, 4, 5, 6, 7]" +mut names := ['John'] +names << 'Peter' +names << 'Sam' +// names << 10 <-- This will not compile. `names` is an array of strings. +``` + +`val in array` returns true if the array contains `val`. See [`in` operator](#in-operator). + +```v +names := ['John', 'Peter', 'Sam'] +println(names.len) // "3" +println('Alex' in names) // "false" +``` + + +#### Array methods + +All arrays can be easily printed with `println(arr)` and converted to a string +with `s := arr.str()`. + +Copying the data from the array is done with `.clone()`: + +```v +nums := [1, 2, 3] +nums_copy := nums.clone() +``` + +Arrays can be efficiently filtered and mapped with the `.filter()` and +`.map()` methods: + +```v +nums := [1, 2, 3, 4, 5, 6] +even := nums.filter(it % 2 == 0) +println(even) // [2, 4, 6] +// filter can accept anonymous functions +even_fn := nums.filter(fn (x int) bool { + return x % 2 == 0 +}) +println(even_fn) +words := ['hello', 'world'] +upper := words.map(it.to_upper()) +println(upper) // ['HELLO', 'WORLD'] +// map can also accept anonymous functions +upper_fn := words.map(fn (w string) string { + return w.to_upper() +}) +println(upper_fn) // ['HELLO', 'WORLD'] +``` + +`it` is a builtin variable which refers to element currently being processed in filter/map methods. + +Additionally, `.any()` and `.all()` can be used to conveniently test +for elements that satisfy a condition. + +```v +nums := [1, 2, 3] +println(nums.any(it == 2)) // true +println(nums.all(it >= 2)) // false +``` + +There are further built in methods for arrays: +* `b := a.repeat(n)` concatenate `n` times the elements of `a` +* `a.insert(i, val)` insert new element `val` at index `i` and move all following elements upwards +* `a.insert(i, [3, 4, 5])` insert several elements +* `a.prepend(val)` insert value at beginning, equivalent to `a.insert(0, val)` +* `a.prepend(arr)` insert elements of array `arr` at beginning +* `a.trim(new_len)` truncate the length (if `new_length < a.len`, otherwise do nothing) +* `a.clear()` empty the array (without changing `cap`, equivalent to `a.trim(0)`) +* `a.delete_many(start, size)` removes `size` consecutive elements beginning with index `start` + – triggers reallocation +* `a.delete(index)` equivalent to `a.delete_many(index, 1)` +* `v := a.first()` equivalent to `v := a[0]` +* `v := a.last()` equivalent to `v := a[a.len - 1]` +* `v := a.pop()` get last element and remove it from array +* `a.delete_last()` remove last element from array +* `b := a.reverse()` make `b` contain the elements of `a` in reversed order +* `a.reverse_in_place()` reverse the order of elements in `a` +* `a.join(joiner)` concatenate array of strings into a string using `joiner` string as a separator + +#### Sorting Arrays + +Sorting arrays of all kinds is very simple and intuitive. Special variables `a` and `b` +are used when providing a custom sorting condition. + +```v +mut numbers := [1, 3, 2] +numbers.sort() // 1, 2, 3 +numbers.sort(a > b) // 3, 2, 1 +``` + +```v +struct User { + age int + name string +} + +mut users := [User{21, 'Bob'}, User{20, 'Zarkon'}, User{25, 'Alice'}] +users.sort(a.age < b.age) // sort by User.age int field +users.sort(a.name > b.name) // reverse sort by User.name string field +``` +V also supports custom sorting, through the `sort_with_compare` array method. +Which expects a comparing function which will define the sort order. +Useful for sorting on multiple fields at the same time by custom sorting rules. +The code below sorts the array ascending on `name` and descending `age`. +```v +struct User { + age int + name string +} + +mut users := [User{21, 'Bob'}, User{65, 'Bob'}, User{25, 'Alice'}] + +custom_sort_fn := fn (a &User, b &User) int { + // return -1 when a comes before b + // return 0, when both are in same order + // return 1 when b comes before a + if a.name == b.name { + if a.age < b.age { + return 1 + } + if a.age > b.age { + return -1 + } + return 0 + } + if a.name < b.name { + return -1 + } else if a.name > b.name { + return 1 + } + return 0 +} +users.sort_with_compare(custom_sort_fn) +``` + +#### Array Slices + +A slice is a part of a parent array. Initially it refers to the elements +between two indices separated by a `..` operator. The right-side index must +be greater than or equal to the left side index. + +If a right-side index is absent, it is assumed to be the array length. If a +left-side index is absent, it is assumed to be 0. + +```v +nums := [0, 10, 20, 30, 40] +println(nums[1..4]) // [10, 20, 30] +println(nums[..4]) // [0, 10, 20, 30] +println(nums[1..]) // [10, 20, 30, 40] +``` + +In V slices are arrays themselves (they are no distinct types). As a result +all array operations may be performed on them. E.g. they can be pushed onto an +array of the same type: + +```v +array_1 := [3, 5, 4, 7, 6] +mut array_2 := [0, 1] +array_2 << array_1[..3] +println(array_2) // `[0, 1, 3, 5, 4]` +``` + +A slice is always created with the smallest possible capacity `cap == len` (see +[`cap` above](#array-initialization)) no matter what the capacity or length +of the parent array is. As a result it is immediately reallocated and copied to another +memory location when the size increases thus becoming independent from the +parent array (*copy on grow*). In particular pushing elements to a slice +does not alter the parent: +```v +mut a := [0, 1, 2, 3, 4, 5] +mut b := a[2..4] +b[0] = 7 // `b[0]` is referring to `a[2]` +println(a) // `[0, 1, 7, 3, 4, 5]` +b << 9 +// `b` has been reallocated and is now independent from `a` +println(a) // `[0, 1, 7, 3, 4, 5]` - no change +println(b) // `[7, 3, 9]` +``` + +Appending to the parent array may or may not make it independent from its child slices. +The behaviour depends on the parent's capacity and is predictable: +```v +mut a := []int{len: 5, cap: 6, init: 2} +mut b := a[1..4] +a << 3 +// no reallocation - fits in `cap` +b[2] = 13 // `a[3]` is modified +a << 4 +// a has been reallocated and is now independent from `b` (`cap` was exceeded) +b[1] = 3 // no change in `a` +println(a) // `[2, 2, 2, 13, 2, 3, 4]` +println(b) // `[2, 3, 13]` +``` + +### Fixed size arrays + +V also supports arrays with fixed size. Unlike ordinary arrays, their +length is constant. You cannot append elements to them, nor shrink them. +You can only modify their elements in place. + +However, access to the elements of fixed size arrays is more efficient, +they need less memory than ordinary arrays, and unlike ordinary arrays, +their data is on the stack, so you may want to use them as buffers if you +do not want additional heap allocations. + +Most methods are defined to work on ordinary arrays, not on fixed size arrays. +You can convert a fixed size array to an ordinary array with slicing: +```v +mut fnums := [3]int{} // fnums is a fixed size array with 3 elements. +fnums[0] = 1 +fnums[1] = 10 +fnums[2] = 100 +println(fnums) // => [1, 10, 100] +println(typeof(fnums).name) // => [3]int + +fnums2 := [1, 10, 100]! // short init syntax that does the same (the syntax will probably change) + +anums := fnums[0..fnums.len] +println(anums) // => [1, 10, 100] +println(typeof(anums).name) // => []int +``` +Note that slicing will cause the data of the fixed size array to be copied to +the newly created ordinary array. + +### Maps + +```v +mut m := map[string]int{} // a map with `string` keys and `int` values +m['one'] = 1 +m['two'] = 2 +println(m['one']) // "1" +println(m['bad_key']) // "0" +println('bad_key' in m) // Use `in` to detect whether such key exists +m.delete('two') +``` +Maps can have keys of type string, rune, integer, float or voidptr. + +The whole map can be initialized using this short syntax: +```v +numbers := { + 'one': 1 + 'two': 2 +} +println(numbers) +``` + +If a key is not found, a zero value is returned by default: + +```v +sm := { + 'abc': 'xyz' +} +val := sm['bad_key'] +println(val) // '' +``` +```v +intm := { + 1: 1234 + 2: 5678 +} +s := intm[3] +println(s) // 0 +``` + +It's also possible to use an `or {}` block to handle missing keys: + +```v +mm := map[string]int{} +val := mm['bad_key'] or { panic('key not found') } +``` + +The same optional check applies to arrays: + +```v +arr := [1, 2, 3] +large_index := 999 +val := arr[large_index] or { panic('out of bounds') } +``` + +## Module imports + +For information about creating a module, see [Modules](#modules). + +Modules can be imported using the `import` keyword: + +```v +import os + +fn main() { + // read text from stdin + name := os.input('Enter your name: ') + println('Hello, $name!') +} +``` +This program can use any public definitions from the `os` module, such +as the `input` function. See the [standard library](https://modules.vlang.io/) +documentation for a list of common modules and their public symbols. + +By default, you have to specify the module prefix every time you call an external function. +This may seem verbose at first, but it makes code much more readable +and easier to understand - it's always clear which function from +which module is being called. This is especially useful in large code bases. + +Cyclic module imports are not allowed, like in Go. + +### Selective imports + +You can also import specific functions and types from modules directly: + +```v +import os { input } + +fn main() { + // read text from stdin + name := input('Enter your name: ') + println('Hello, $name!') +} +``` +Note: This will import the module as well. Also, this is not allowed for +constants - they must always be prefixed. + +You can import several specific symbols at once: + +```v +import os { input, user_os } + +name := input('Enter your name: ') +println('Name: $name') +os := user_os() +println('Your OS is ${os}.') +``` + +### Module import aliasing + +Any imported module name can be aliased using the `as` keyword: + +NOTE: this example will not compile unless you have created `mymod/sha256.v` +```v failcompile +import crypto.sha256 +import mymod.sha256 as mysha256 + +fn main() { + v_hash := sha256.sum('hi'.bytes()).hex() + my_hash := mysha256.sum('hi'.bytes()).hex() + assert my_hash == v_hash +} +``` + +You cannot alias an imported function or type. +However, you _can_ redeclare a type. + +```v +import time +import math + +type MyTime = time.Time + +fn (mut t MyTime) century() int { + return int(1.0 + math.trunc(f64(t.year) * 0.009999794661191)) +} + +fn main() { + mut my_time := MyTime{ + year: 2020 + month: 12 + day: 25 + } + println(time.new_time(my_time).utc_string()) + println('Century: $my_time.century()') +} +``` + +## Statements & expressions + +### If + +```v +a := 10 +b := 20 +if a < b { + println('$a < $b') +} else if a > b { + println('$a > $b') +} else { + println('$a == $b') +} +``` + +`if` statements are pretty straightforward and similar to most other languages. +Unlike other C-like languages, +there are no parentheses surrounding the condition and the braces are always required. + +`if` can be used as an expression: + +```v +num := 777 +s := if num % 2 == 0 { 'even' } else { 'odd' } +println(s) +// "odd" +``` + +#### Type checks and casts +You can check the current type of a sum type using `is` and its negated form `!is`. + +You can do it either in an `if`: +```v +struct Abc { + val string +} + +struct Xyz { + foo string +} + +type Alphabet = Abc | Xyz + +x := Alphabet(Abc{'test'}) // sum type +if x is Abc { + // x is automatically casted to Abc and can be used here + println(x) +} +if x !is Abc { + println('Not Abc') +} +``` +or using `match`: +```v oksyntax +match x { + Abc { + // x is automatically casted to Abc and can be used here + println(x) + } + Xyz { + // x is automatically casted to Xyz and can be used here + println(x) + } +} +``` + +This works also with struct fields: +```v +struct MyStruct { + x int +} + +struct MyStruct2 { + y string +} + +type MySumType = MyStruct | MyStruct2 + +struct Abc { + bar MySumType +} + +x := Abc{ + bar: MyStruct{123} // MyStruct will be converted to MySumType type automatically +} +if x.bar is MyStruct { + // x.bar is automatically casted + println(x.bar) +} +match x.bar { + MyStruct { + // x.bar is automatically casted + println(x.bar) + } + else {} +} +``` + +Mutable variables can change, and doing a cast would be unsafe. +However, sometimes it's useful to type cast despite mutability. +In such cases the developer must mark the expression with the `mut` keyword +to tell the compiler that they know what they're doing. + +It works like this: +```v oksyntax +mut x := MySumType(MyStruct{123}) +if mut x is MyStruct { + // x is casted to MyStruct even if it's mutable + // without the mut keyword that wouldn't work + println(x) +} +// same with match +match mut x { + MyStruct { + // x is casted to MyStruct even it's mutable + // without the mut keyword that wouldn't work + println(x) + } +} +``` + +### In operator + +`in` allows to check whether an array or a map contains an element. +To do the opposite, use `!in`. + +```v +nums := [1, 2, 3] +println(1 in nums) // true +println(4 !in nums) // true +m := { + 'one': 1 + 'two': 2 +} +println('one' in m) // true +println('three' !in m) // true +``` + +It's also useful for writing boolean expressions that are clearer and more compact: + +```v +enum Token { + plus + minus + div + mult +} + +struct Parser { + token Token +} + +parser := Parser{} +if parser.token == .plus || parser.token == .minus || parser.token == .div || parser.token == .mult { + // ... +} +if parser.token in [.plus, .minus, .div, .mult] { + // ... +} +``` + +V optimizes such expressions, +so both `if` statements above produce the same machine code and no arrays are created. + +### For loop + +V has only one looping keyword: `for`, with several forms. + +#### `for`/`in` + +This is the most common form. You can use it with an array, map or +numeric range. + +##### Array `for` + +```v +numbers := [1, 2, 3, 4, 5] +for num in numbers { + println(num) +} +names := ['Sam', 'Peter'] +for i, name in names { + println('$i) $name') + // Output: 0) Sam + // 1) Peter +} +``` + +The `for value in arr` form is used for going through elements of an array. +If an index is required, an alternative form `for index, value in arr` can be used. + +Note, that the value is read-only. +If you need to modify the array while looping, you need to declare the element as mutable: + +```v +mut numbers := [0, 1, 2] +for mut num in numbers { + num++ +} +println(numbers) // [1, 2, 3] +``` +When an identifier is just a single underscore, it is ignored. + +##### Custom iterators +Types that implement a `next` method returning an `Option` can be iterated +with a `for` loop. + +```v +struct SquareIterator { + arr []int +mut: + idx int +} + +fn (mut iter SquareIterator) next() ?int { + if iter.idx >= iter.arr.len { + return error('') + } + defer { + iter.idx++ + } + return iter.arr[iter.idx] * iter.arr[iter.idx] +} + +nums := [1, 2, 3, 4, 5] +iter := SquareIterator{ + arr: nums +} +for squared in iter { + println(squared) +} +``` + +The code above prints: +``` +1 +4 +9 +16 +25 +``` + +##### Map `for` + +```v +m := { + 'one': 1 + 'two': 2 +} +for key, value in m { + println('$key -> $value') + // Output: one -> 1 + // two -> 2 +} +``` + +Either key or value can be ignored by using a single underscore as the identifier. +```v +m := { + 'one': 1 + 'two': 2 +} +// iterate over keys +for key, _ in m { + println(key) + // Output: one + // two +} +// iterate over values +for _, value in m { + println(value) + // Output: 1 + // 2 +} +``` + +##### Range `for` + +```v +// Prints '01234' +for i in 0 .. 5 { + print(i) +} +``` +`low..high` means an *exclusive* range, which represents all values +from `low` up to *but not including* `high`. + +#### Condition `for` + +```v +mut sum := 0 +mut i := 0 +for i <= 100 { + sum += i + i++ +} +println(sum) // "5050" +``` + +This form of the loop is similar to `while` loops in other languages. +The loop will stop iterating once the boolean condition evaluates to false. +Again, there are no parentheses surrounding the condition, and the braces are always required. + +#### Bare `for` + +```v +mut num := 0 +for { + num += 2 + if num >= 10 { + break + } +} +println(num) // "10" +``` + +The condition can be omitted, resulting in an infinite loop. + +#### C `for` + +```v +for i := 0; i < 10; i += 2 { + // Don't print 6 + if i == 6 { + continue + } + println(i) +} +``` + +Finally, there's the traditional C style `for` loop. It's safer than the `while` form +because with the latter it's easy to forget to update the counter and get +stuck in an infinite loop. + +Here `i` doesn't need to be declared with `mut` since it's always going to be mutable by definition. + +#### Labelled break & continue + +`break` and `continue` control the innermost `for` loop by default. +You can also use `break` and `continue` followed by a label name to refer to an outer `for` +loop: + +```v +outer: for i := 4; true; i++ { + println(i) + for { + if i < 7 { + continue outer + } else { + break outer + } + } +} +``` +The label must immediately precede the outer loop. +The above code prints: +``` +4 +5 +6 +7 +``` + +### Match + +```v +os := 'windows' +print('V is running on ') +match os { + 'darwin' { println('macOS.') } + 'linux' { println('Linux.') } + else { println(os) } +} +``` + +A match statement is a shorter way to write a sequence of `if - else` statements. +When a matching branch is found, the following statement block will be run. +The else branch will be run when no other branches match. + +```v +number := 2 +s := match number { + 1 { 'one' } + 2 { 'two' } + else { 'many' } +} +``` + +A match expression returns the value of the final expression from the matching branch. + +```v +enum Color { + red + blue + green +} + +fn is_red_or_blue(c Color) bool { + return match c { + .red, .blue { true } // comma can be used to test multiple values + .green { false } + } +} +``` + +A match statement can also be used to branch on the variants of an `enum` +by using the shorthand `.variant_here` syntax. An `else` branch is not allowed +when all the branches are exhaustive. + +```v +c := `v` +typ := match c { + `0`...`9` { 'digit' } + `A`...`Z` { 'uppercase' } + `a`...`z` { 'lowercase' } + else { 'other' } +} +println(typ) +// 'lowercase' +``` + +You can also use ranges as `match` patterns. If the value falls within the range +of a branch, that branch will be executed. + +Note that the ranges use `...` (three dots) rather than `..` (two dots). This is +because the range is *inclusive* of the last element, rather than exclusive +(as `..` ranges are). Using `..` in a match branch will throw an error. + +Note: `match` as an expression is not usable in `for` loop and `if` statements. + +### Defer + +A defer statement defers the execution of a block of statements +until the surrounding function returns. + +```v +import os + +fn read_log() { + mut ok := false + mut f := os.open('log.txt') or { panic(err.msg) } + defer { + f.close() + } + // ... + if !ok { + // defer statement will be called here, the file will be closed + return + } + // ... + // defer statement will be called here, the file will be closed +} +``` + +If the function returns a value the `defer` block is executed *after* the return +expression is evaluated: + +```v +import os + +enum State { + normal + write_log + return_error +} + +// write log file and return number of bytes written +fn write_log(s State) ?int { + mut f := os.create('log.txt') ? + defer { + f.close() + } + if s == .write_log { + // `f.close()` will be called after `f.write()` has been + // executed, but before `write_log()` finally returns the + // number of bytes written to `main()` + return f.writeln('This is a log file') + } else if s == .return_error { + // the file will be closed after the `error()` function + // has returned - so the error message will still report + // it as open + return error('nothing written; file open: $f.is_opened') + } + // the file will be closed here, too + return 0 +} + +fn main() { + n := write_log(.return_error) or { + println('Error: $err') + 0 + } + println('$n bytes written') +} +``` + +## Structs + +```v +struct Point { + x int + y int +} + +mut p := Point{ + x: 10 + y: 20 +} +println(p.x) // Struct fields are accessed using a dot +// Alternative literal syntax for structs with 3 fields or fewer +p = Point{10, 20} +assert p.x == 10 +``` + +### Heap structs + +Structs are allocated on the stack. To allocate a struct on the heap +and get a reference to it, use the `&` prefix: + +```v +struct Point { + x int + y int +} + +p := &Point{10, 10} +// References have the same syntax for accessing fields +println(p.x) +``` + +The type of `p` is `&Point`. It's a [reference](#references) to `Point`. +References are similar to Go pointers and C++ references. + +### Embedded structs + +V doesn't allow subclassing, but it supports embedded structs: + +```v +struct Widget { +mut: + x int + y int +} + +struct Button { + Widget + title string +} + +mut button := Button{ + title: 'Click me' +} +button.x = 3 +``` +Without embedding we'd have to name the `Widget` field and do: + +```v oksyntax +button.widget.x = 3 +``` + +### Default field values + +```v +struct Foo { + n int // n is 0 by default + s string // s is '' by default + a []int // a is `[]int{}` by default + pos int = -1 // custom default value +} +``` + +All struct fields are zeroed by default during the creation of the struct. +Array and map fields are allocated. + +It's also possible to define custom default values. + +### Required fields + +```v +struct Foo { + n int [required] +} +``` + +You can mark a struct field with the `[required]` attribute, to tell V that +that field must be initialized when creating an instance of that struct. + +This example will not compile, since the field `n` isn't explicitly initialized: +```v failcompile +_ = Foo{} +``` + + + +### Short struct literal syntax + +```v +struct Point { + x int + y int +} + +mut p := Point{ + x: 10 + y: 20 +} +// you can omit the struct name when it's already known +p = Point{ + x: 30 + y: 4 +} +assert p.y == 4 +// +// array: first element defines type of array +points := [Point{10, 20}, Point{20, 30}, Point{40, 50}] +println(points) // [Point{x: 10, y: 20}, Point{x: 20, y: 30}, Point{x: 40,y: 50}] +``` + +Omitting the struct name also works for returning a struct literal or passing one +as a function argument. + +#### Trailing struct literal arguments + +V doesn't have default function arguments or named arguments, for that trailing struct +literal syntax can be used instead: + +```v +struct ButtonConfig { + text string + is_disabled bool + width int = 70 + height int = 20 +} + +struct Button { + text string + width int + height int +} + +fn new_button(c ButtonConfig) &Button { + return &Button{ + width: c.width + height: c.height + text: c.text + } +} + +button := new_button(text: 'Click me', width: 100) +// the height is unset, so it's the default value +assert button.height == 20 +``` + +As you can see, both the struct name and braces can be omitted, instead of: + +```v oksyntax nofmt +new_button(ButtonConfig{text:'Click me', width:100}) +``` + +This only works for functions that take a struct for the last argument. + +### Access modifiers + +Struct fields are private and immutable by default (making structs immutable as well). +Their access modifiers can be changed with +`pub` and `mut`. In total, there are 5 possible options: + +```v +struct Foo { + a int // private immutable (default) +mut: + b int // private mutable + c int // (you can list multiple fields with the same access modifier) +pub: + d int // public immutable (readonly) +pub mut: + e int // public, but mutable only in parent module +__global: + // (not recommended to use, that's why the 'global' keyword starts with __) + f int // public and mutable both inside and outside parent module +} +``` + +For example, here's the `string` type defined in the `builtin` module: + +```v ignore +struct string { + str &byte +pub: + len int +} +``` + +It's easy to see from this definition that `string` is an immutable type. +The byte pointer with the string data is not accessible outside `builtin` at all. +The `len` field is public, but immutable: +```v failcompile +fn main() { + str := 'hello' + len := str.len // OK + str.len++ // Compilation error +} +``` + +This means that defining public readonly fields is very easy in V, +no need in getters/setters or properties. + +## Methods + +```v +struct User { + age int +} + +fn (u User) can_register() bool { + return u.age > 16 +} + +user := User{ + age: 10 +} +println(user.can_register()) // "false" +user2 := User{ + age: 20 +} +println(user2.can_register()) // "true" +``` + +V doesn't have classes, but you can define methods on types. +A method is a function with a special receiver argument. +The receiver appears in its own argument list between the `fn` keyword and the method name. +Methods must be in the same module as the receiver type. + +In this example, the `can_register` method has a receiver of type `User` named `u`. +The convention is not to use receiver names like `self` or `this`, +but a short, preferably one letter long, name. + +## Unions + +Just like structs, unions support embedding. + +```v +struct Rgba32_Component { + r byte + g byte + b byte + a byte +} + +union Rgba32 { + Rgba32_Component + value u32 +} + +clr1 := Rgba32{ + value: 0x008811FF +} + +clr2 := Rgba32{ + Rgba32_Component: Rgba32_Component{ + a: 128 + } +} + +sz := sizeof(Rgba32) +unsafe { + println('Size: ${sz}B,clr1.b: $clr1.b,clr2.b: $clr2.b') +} +``` + +Output: `Size: 4B, clr1.b: 136, clr2.b: 0` + +Union member access must be performed in an `unsafe` block. + +Note that the embedded struct arguments are not necessarily stored in the order listed. + +## Functions 2 + +### Pure functions by default + +V functions are pure by default, meaning that their return values are a function of their +arguments only, and their evaluation has no side effects (besides I/O). + +This is achieved by a lack of global variables and all function arguments being +immutable by default, even when [references](#references) are passed. + +V is not a purely functional language however. + +There is a compiler flag to enable global variables (`-enable-globals`), but this is +intended for low-level applications like kernels and drivers. + +### Mutable arguments + +It is possible to modify function arguments by using the keyword `mut`: + +```v +struct User { + name string +mut: + is_registered bool +} + +fn (mut u User) register() { + u.is_registered = true +} + +mut user := User{} +println(user.is_registered) // "false" +user.register() +println(user.is_registered) // "true" +``` + +In this example, the receiver (which is simply the first argument) is marked as mutable, +so `register()` can change the user object. The same works with non-receiver arguments: + +```v +fn multiply_by_2(mut arr []int) { + for i in 0 .. arr.len { + arr[i] *= 2 + } +} + +mut nums := [1, 2, 3] +multiply_by_2(mut nums) +println(nums) +// "[2, 4, 6]" +``` + +Note, that you have to add `mut` before `nums` when calling this function. This makes +it clear that the function being called will modify the value. + +It is preferable to return values instead of modifying arguments. +Modifying arguments should only be done in performance-critical parts of your application +to reduce allocations and copying. + +For this reason V doesn't allow the modification of arguments with primitive types (e.g. integers). +Only more complex types such as arrays and maps may be modified. + +Use `user.register()` or `user = register(user)` +instead of `register(mut user)`. + +#### Struct update syntax + +V makes it easy to return a modified version of an object: + +```v +struct User { + name string + age int + is_registered bool +} + +fn register(u User) User { + return User{ + ...u + is_registered: true + } +} + +mut user := User{ + name: 'abc' + age: 23 +} +user = register(user) +println(user) +``` + +### Variable number of arguments + +```v +fn sum(a ...int) int { + mut total := 0 + for x in a { + total += x + } + return total +} + +println(sum()) // 0 +println(sum(1)) // 1 +println(sum(2, 3)) // 5 +// using array decomposition +a := [2, 3, 4] +println(sum(...a)) // <-- using prefix ... here. output: 9 +b := [5, 6, 7] +println(sum(...b)) // output: 18 +``` + +### Anonymous & higher order functions + +```v +fn sqr(n int) int { + return n * n +} + +fn cube(n int) int { + return n * n * n +} + +fn run(value int, op fn (int) int) int { + return op(value) +} + +fn main() { + // Functions can be passed to other functions + println(run(5, sqr)) // "25" + // Anonymous functions can be declared inside other functions: + double_fn := fn (n int) int { + return n + n + } + println(run(5, double_fn)) // "10" + // Functions can be passed around without assigning them to variables: + res := run(5, fn (n int) int { + return n + n + }) + println(res) // "10" + // You can even have an array/map of functions: + fns := [sqr, cube] + println(fns[0](10)) // "100" + fns_map := { + 'sqr': sqr + 'cube': cube + } + println(fns_map['cube'](2)) // "8" +} +``` + +V supports closures too. +This means that anonymous functions can inherit variables from the scope they were created in. +They must do so explicitly by listing all variables that are inherited. + +> Warning: currently works on Unix-based, x64 architectures only. +Some work is in progress to make closures work on Windows, then other architectures. + +```v oksyntax +my_int := 1 +my_closure := fn [my_int] () { + println(my_int) +} +my_closure() // prints 1 +``` + +Inherited variables are copied when the anonymous function is created. +This means that if the original variable is modified after the creation of the function, +the modification won't be reflected in the function. + +```v oksyntax +mut i := 1 +func := fn [i] () int { + return i +} +println(func() == 1) // true +i = 123 +println(func() == 1) // still true +``` + +However, the variable can be modified inside the anonymous function. +The change won't be reflected outside, but will be in the later function calls. + +```v oksyntax +fn new_counter() fn () int { + mut i := 0 + return fn [mut i] () int { + i++ + return i + } +} + +c := new_counter() +println(c()) // 1 +println(c()) // 2 +println(c()) // 3 +``` + +If you need the value to be modified outside the function, use a reference. +**Warning**: _you need to make sure the reference is always valid, +otherwise this can result in undefined behavior._ + +```v oksyntax +mut i := 0 +mut ref := &i +print_counter := fn [ref] () { + println(*ref) +} + +print_counter() // 0 +i = 10 +print_counter() // 10 +``` + +## References + +```v +struct Foo {} + +fn (foo Foo) bar_method() { + // ... +} + +fn bar_function(foo Foo) { + // ... +} +``` + +If a function argument is immutable (like `foo` in the examples above) +V can pass it either by value or by reference. The compiler will decide, +and the developer doesn't need to think about it. + +You no longer need to remember whether you should pass the struct by value +or by reference. + +You can ensure that the struct is always passed by reference by +adding `&`: + +```v +struct Foo { + abc int +} + +fn (foo &Foo) bar() { + println(foo.abc) +} +``` + +`foo` is still immutable and can't be changed. For that, +`(mut foo Foo)` must be used. + +In general, V's references are similar to Go pointers and C++ references. +For example, a generic tree structure definition would look like this: + +```v +struct Node { + val T + left &Node + right &Node +} +``` + +## Constants + +```v +const ( + pi = 3.14 + world = '世界' +) + +println(pi) +println(world) +``` + +Constants are declared with `const`. They can only be defined +at the module level (outside of functions). +Constant values can never be changed. You can also declare a single +constant separately: + +```v +const e = 2.71828 +``` + +V constants are more flexible than in most languages. You can assign more complex values: + +```v +struct Color { + r int + g int + b int +} + +fn rgb(r int, g int, b int) Color { + return Color{ + r: r + g: g + b: b + } +} + +const ( + numbers = [1, 2, 3] + red = Color{ + r: 255 + g: 0 + b: 0 + } + // evaluate function call at compile-time* + blue = rgb(0, 0, 255) +) + +println(numbers) +println(red) +println(blue) +``` +\* WIP - for now function calls are evaluated at program start-up + +Global variables are not normally allowed, so this can be really useful. + +**Modules** + +Constants can be made public with `pub const`: +```v oksyntax +module mymodule + +pub const golden_ratio = 1.61803 + +fn calc() { + println(mymodule.golden_ratio) +} +``` +The `pub` keyword is only allowed before the `const` keyword and cannot be used inside +a `const ( )` block. + +Outside from module main all constants need to be prefixed with the module name. + +### Required module prefix + +When naming constants, `snake_case` must be used. In order to distinguish consts +from local variables, the full path to consts must be specified. For example, +to access the PI const, full `math.pi` name must be used both outside the `math` +module, and inside it. That restriction is relaxed only for the `main` module +(the one containing your `fn main()`), where you can use the unqualified name of +constants defined there, i.e. `numbers`, rather than `main.numbers`. + +vfmt takes care of this rule, so you can type `println(pi)` inside the `math` module, +and vfmt will automatically update it to `println(math.pi)`. + + + +## Builtin functions + +Some functions are builtin like `println`. Here is the complete list: + +```v ignore +fn print(s string) // print anything on sdtout +fn println(s string) // print anything and a newline on sdtout + +fn eprint(s string) // same as print(), but use stderr +fn eprintln(s string) // same as println(), but use stderr + +fn exit(code int) // terminate the program with a custom error code +fn panic(s string) // print a message and backtraces on stderr, and terminate the program with error code 1 +fn print_backtrace() // print backtraces on stderr +``` + +`println` is a simple yet powerful builtin function, that can print anything: +strings, numbers, arrays, maps, structs. + +```v +struct User { + name string + age int +} + +println(1) // "1" +println('hi') // "hi" +println([1, 2, 3]) // "[1, 2, 3]" +println(User{ name: 'Bob', age: 20 }) // "User{name:'Bob', age:20}" +``` + + + +## Printing custom types + +If you want to define a custom print value for your type, simply define a +`.str() string` method: + +```v +struct Color { + r int + g int + b int +} + +pub fn (c Color) str() string { + return '{$c.r, $c.g, $c.b}' +} + +red := Color{ + r: 255 + g: 0 + b: 0 +} +println(red) +``` + +## Modules + +Every file in the root of a folder is part of the same module. +Simple programs don't need to specify module name, in which case it defaults to 'main'. + +V is a very modular language. Creating reusable modules is encouraged and is +quite easy to do. +To create a new module, create a directory with your module's name containing +.v files with code: + +```shell +cd ~/code/modules +mkdir mymodule +vim mymodule/myfile.v +``` +```v failcompile +// myfile.v +module mymodule + +// To export a function we have to use `pub` +pub fn say_hi() { + println('hello from mymodule!') +} +``` + +You can now use `mymodule` in your code: + +```v failcompile +import mymodule + +fn main() { + mymodule.say_hi() +} +``` + +* Module names should be short, under 10 characters. +* Module names must use `snake_case`. +* Circular imports are not allowed. +* You can have as many .v files in a module as you want. +* You can create modules anywhere. +* All modules are compiled statically into a single executable. + +### `init` functions + +If you want a module to automatically call some setup/initialization code when it is imported, +you can use a module `init` function: + +```v +fn init() { + // your setup code here ... +} +``` + +The `init` function cannot be public - it will be called automatically. This feature is +particularly useful for initializing a C library. + +### Manage Packages + +Briefly: + +```powershell +v [module option] [param] +``` + +###### module options: + +``` + install Install a module from VPM. + remove Remove a module that was installed from VPM. + search Search for a module from VPM. + update Update an installed module from VPM. + upgrade Upgrade all the outdated modules. + list List all installed modules. + outdated Show installed modules that need updates. +``` + +Read more: + +You can also install modules already created by someone else with [VPM](https://vpm.vlang.io/): +```powershell +v install [module] +``` +**Example:** +```powershell +v install ui +``` + +Modules could install directly from git or mercurial repositories. +```powershell +v install [--git|--hg] [url] +``` +**Example:** +```powershell +v install --git https://github.com/vlang/markdown +``` + +Removing a module with v: + +```powershell +v remove [module] +``` +**Example:** +```powershell +v remove ui +``` + +Updating an installed module from [VPM](https://vpm.vlang.io/): + +```powershell +v update [module] +``` +**Example:** +```powershell +v update ui +``` + +Or you can update all your modules: +```powershell +v update +``` + +To see all the modules you have installed, you can use: + +```powershell +v list +``` +**Example:** +```powershell +> v list +Installed modules: + markdown + ui +``` + +To see all the modules you have installed, you can use: +outdated Show installed modules that need updates. +```powershell +v outdated +``` +**Example:** +```powershell +> v outdated +Modules are up to date. +``` + +### Publish package + +1.

However, reserved keywords may be escaped +with an @. + +```v +enum Color { + @none + red + green + blue +} + +color := Color.@none +println(color) +``` + +Integers may be assigned to enum fields. + +```v +enum Grocery { + apple + orange = 5 + pear +} + +g1 := int(Grocery.apple) +g2 := int(Grocery.orange) +g3 := int(Grocery.pear) +println('Grocery IDs: $g1, $g2, $g3') +``` + +Output: `Grocery IDs: 0, 5, 6`. + +Operations are not allowed on enum variables; they must be explicity cast to `int`. + +### Sum types + +A sum type instance can hold a value of several different types. Use the `type` +keyword to declare a sum type: + +```v +struct Moon {} + +struct Mars {} + +struct Venus {} + +type World = Mars | Moon | Venus + +sum := World(Moon{}) +assert sum.type_name() == 'Moon' +println(sum) +``` +The built-in method `type_name` returns the name of the currently held +type. + +With sum types you could build recursive structures and write concise but powerful code on them. +```v +// V's binary tree +struct Empty {} + +struct Node { + value f64 + left Tree + right Tree +} + +type Tree = Empty | Node + +// sum up all node values +fn sum(tree Tree) f64 { + return match tree { + Empty { 0 } + Node { tree.value + sum(tree.left) + sum(tree.right) } + } +} + +fn main() { + left := Node{0.2, Empty{}, Empty{}} + right := Node{0.3, Empty{}, Node{0.4, Empty{}, Empty{}}} + tree := Node{0.5, left, right} + println(sum(tree)) // 0.2 + 0.3 + 0.4 + 0.5 = 1.4 +} +``` + +Enums can have methods, just like structs + +```v +enum Cycle { + one + two + three +} + +fn (c Cycle) next() Cycle { + match c { + .one { + return .two + } + .two { + return .three + } + .three { + return .one + } + } +} + +mut c := Cycle.one +for _ in 0 .. 10 { + println(c) + c = c.next() +} +``` + +Output: +``` +one +two +three +one +two +three +one +two +three +one +``` + +#### Dynamic casts + +To check whether a sum type instance holds a certain type, use `sum is Type`. +To cast a sum type to one of its variants you can use `sum as Type`: + +```v +struct Moon {} + +struct Mars {} + +struct Venus {} + +type World = Mars | Moon | Venus + +fn (m Mars) dust_storm() bool { + return true +} + +fn main() { + mut w := World(Moon{}) + assert w is Moon + w = Mars{} + // use `as` to access the Mars instance + mars := w as Mars + if mars.dust_storm() { + println('bad weather!') + } +} +``` + +`as` will panic if `w` doesn't hold a `Mars` instance. +A safer way is to use a smart cast. + +#### Smart casting + +```v oksyntax +if w is Mars { + assert typeof(w).name == 'Mars' + if w.dust_storm() { + println('bad weather!') + } +} +``` +`w` has type `Mars` inside the body of the `if` statement. This is +known as *flow-sensitive typing*. +If `w` is a mutable identifier, it would be unsafe if the compiler smart casts it without a warning. +That's why you have to declare a `mut` before the `is` expression: + +```v ignore +if mut w is Mars { + assert typeof(w).name == 'Mars' + if w.dust_storm() { + println('bad weather!') + } +} +``` +Otherwise `w` would keep its original type. +> This works for both, simple variables and complex expressions like `user.name` + +#### Matching sum types + +You can also use `match` to determine the variant: + +```v +struct Moon {} + +struct Mars {} + +struct Venus {} + +type World = Mars | Moon | Venus + +fn open_parachutes(n int) { + println(n) +} + +fn land(w World) { + match w { + Moon {} // no atmosphere + Mars { + // light atmosphere + open_parachutes(3) + } + Venus { + // heavy atmosphere + open_parachutes(1) + } + } +} +``` + +`match` must have a pattern for each variant or have an `else` branch. + +```v ignore +struct Moon {} +struct Mars {} +struct Venus {} + +type World = Moon | Mars | Venus + +fn (m Moon) moon_walk() {} +fn (m Mars) shiver() {} +fn (v Venus) sweat() {} + +fn pass_time(w World) { + match w { + // using the shadowed match variable, in this case `w` (smart cast) + Moon { w.moon_walk() } + Mars { w.shiver() } + else {} + } +} +``` + +### Type aliases + +To define a new type `NewType` as an alias for `ExistingType`, +do `type NewType = ExistingType`.
    +This is a special case of a [sum type](#sum-types) declaration. + +### Option/Result types and error handling + +Option types are declared with `?Type`: +```v +struct User { + id int + name string +} + +struct Repo { + users []User +} + +fn (r Repo) find_user_by_id(id int) ?User { + for user in r.users { + if user.id == id { + // V automatically wraps this into an option type + return user + } + } + return error('User $id not found') +} + +fn main() { + repo := Repo{ + users: [User{1, 'Andrew'}, User{2, 'Bob'}, User{10, 'Charles'}] + } + user := repo.find_user_by_id(10) or { // Option types must be handled by `or` blocks + return + } + println(user.id) // "10" + println(user.name) // "Charles" +} +``` + +V combines `Option` and `Result` into one type, so you don't need to decide which one to use. + +The amount of work required to "upgrade" a function to an optional function is minimal; +you have to add a `?` to the return type and return an error when something goes wrong. + +If you don't need to return an error message, you can simply `return none` +(this is a more efficient equivalent of `return error("")`). + +This is the primary mechanism for error handling in V. They are still values, like in Go, +but the advantage is that errors can't be unhandled, and handling them is a lot less verbose. +Unlike other languages, V does not handle exceptions with `throw/try/catch` blocks. + +`err` is defined inside an `or` block and is set to the string message passed +to the `error()` function. `err` is empty if `none` was returned. + +```v oksyntax +user := repo.find_user_by_id(7) or { + println(err) // "User 7 not found" + return +} +``` + +### Handling optionals + +There are four ways of handling an optional. The first method is to +propagate the error: + +```v +import net.http + +fn f(url string) ?string { + resp := http.get(url) ? + return resp.text +} +``` + +`http.get` returns `?http.Response`. Because `?` follows the call, the +error will be propagated to the caller of `f`. When using `?` after a +function call producing an optional, the enclosing function must return +an optional as well. If error propagation is used in the `main()` +function it will `panic` instead, since the error cannot be propagated +any further. + +The body of `f` is essentially a condensed version of: + +```v ignore + resp := http.get(url) or { return err } + return resp.text +``` + +--- +The second method is to break from execution early: + +```v oksyntax +user := repo.find_user_by_id(7) or { return } +``` + +Here, you can either call `panic()` or `exit()`, which will stop the execution of the +entire program, or use a control flow statement (`return`, `break`, `continue`, etc) +to break from the current block. +Note that `break` and `continue` can only be used inside a `for` loop. + +V does not have a way to forcibly "unwrap" an optional (as other languages do, +for instance Rust's `unwrap()` or Swift's `!`). To do this, use `or { panic(err.msg) }` instead. + +--- +The third method is to provide a default value at the end of the `or` block. +In case of an error, that value would be assigned instead, +so it must have the same type as the content of the `Option` being handled. + +```v +fn do_something(s string) ?string { + if s == 'foo' { + return 'foo' + } + return error('invalid string') // Could be `return none` as well +} + +a := do_something('foo') or { 'default' } // a will be 'foo' +b := do_something('bar') or { 'default' } // b will be 'default' +println(a) +println(b) +``` + +--- +The fourth method is to use `if` unwrapping: + +```v +import net.http + +if resp := http.get('https://google.com') { + println(resp.text) // resp is a http.Response, not an optional +} else { + println(err) +} +``` +Above, `http.get` returns a `?http.Response`. `resp` is only in scope for the first +`if` branch. `err` is only in scope for the `else` branch. + +## Generics + +```v wip + +struct Repo { + db DB +} + +struct User { + id int + name string +} + +struct Post { + id int + user_id int + title string + body string +} + +fn new_repo(db DB) Repo { + return Repo{db: db} +} + +// This is a generic function. V will generate it for every type it's used with. +fn (r Repo) find_by_id(id int) ?T { + table_name := T.name // in this example getting the name of the type gives us the table name + return r.db.query_one('select * from $table_name where id = ?', id) +} + +db := new_db() +users_repo := new_repo(db) // returns Repo +posts_repo := new_repo(db) // returns Repo +user := users_repo.find_by_id(1)? // find_by_id +post := posts_repo.find_by_id(1)? // find_by_id +``` + +Currently generic function definitions must declare their type parameters, but in +future V will infer generic type parameters from single-letter type names in +runtime parameter types. This is why `find_by_id` can omit ``, because the +receiver argument `r` uses a generic type `T`. + +Another example: +```v +fn compare(a T, b T) int { + if a < b { + return -1 + } + if a > b { + return 1 + } + return 0 +} + +// compare +println(compare(1, 0)) // Outputs: 1 +println(compare(1, 1)) // 0 +println(compare(1, 2)) // -1 +// compare +println(compare('1', '0')) // Outputs: 1 +println(compare('1', '1')) // 0 +println(compare('1', '2')) // -1 +// compare +println(compare(1.1, 1.0)) // Outputs: 1 +println(compare(1.1, 1.1)) // 0 +println(compare(1.1, 1.2)) // -1 +``` + + +## Concurrency +### Spawning Concurrent Tasks +V's model of concurrency is very similar to Go's. To run `foo()` concurrently in +a different thread, just call it with `go foo()`: + +```v +import math + +fn p(a f64, b f64) { // ordinary function without return value + c := math.sqrt(a * a + b * b) + println(c) +} + +fn main() { + go p(3, 4) + // p will be run in parallel thread +} +``` + +Sometimes it is necessary to wait until a parallel thread has finished. This can +be done by assigning a *handle* to the started thread and calling the `wait()` method +to this handle later: + +```v +import math + +fn p(a f64, b f64) { // ordinary function without return value + c := math.sqrt(a * a + b * b) + println(c) // prints `5` +} + +fn main() { + h := go p(3, 4) + // p() runs in parallel thread + h.wait() + // p() has definitely finished +} +``` + +This approach can also be used to get a return value from a function that is run in a +parallel thread. There is no need to modify the function itself to be able to call it +concurrently. + +```v +import math { sqrt } + +fn get_hypot(a f64, b f64) f64 { // ordinary function returning a value + c := sqrt(a * a + b * b) + return c +} + +fn main() { + g := go get_hypot(54.06, 2.08) // spawn thread and get handle to it + h1 := get_hypot(2.32, 16.74) // do some other calculation here + h2 := g.wait() // get result from spawned thread + println('Results: $h1, $h2') // prints `Results: 16.9, 54.1` +} +``` + +If there is a large number of tasks, it might be easier to manage them +using an array of threads. + +```v +import time + +fn task(id int, duration int) { + println('task $id begin') + time.sleep(duration * time.millisecond) + println('task $id end') +} + +fn main() { + mut threads := []thread{} + threads << go task(1, 500) + threads << go task(2, 900) + threads << go task(3, 100) + threads.wait() + println('done') +} + +// Output: +// task 1 begin +// task 2 begin +// task 3 begin +// task 3 end +// task 1 end +// task 2 end +// done +``` + +Additionally for threads that return the same type, calling `wait()` +on the thread array will return all computed values. + +```v +fn expensive_computing(i int) int { + return i * i +} + +fn main() { + mut threads := []thread int{} + for i in 1 .. 10 { + threads << go expensive_computing(i) + } + // Join all tasks + r := threads.wait() + println('All jobs finished: $r') +} + +// Output: All jobs finished: [1, 4, 9, 16, 25, 36, 49, 64, 81] +``` + +### Channels +Channels are the preferred way to communicate between coroutines. V's channels work basically like +those in Go. You can push objects into a channel on one end and pop objects from the other end. +Channels can be buffered or unbuffered and it is possible to `select` from multiple channels. + +#### Syntax and Usage +Channels have the type `chan objtype`. An optional buffer length can specified as the `cap` property +in the declaration: + +```v +ch := chan int{} // unbuffered - "synchronous" +ch2 := chan f64{cap: 100} // buffer length 100 +``` + +Channels do not have to be declared as `mut`. The buffer length is not part of the type but +a property of the individual channel object. Channels can be passed to coroutines like normal +variables: + +```v +fn f(ch chan int) { + // ... +} + +fn main() { + ch := chan int{} + go f(ch) + // ... +} +``` + +Objects can be pushed to channels using the arrow operator. The same operator can be used to +pop objects from the other end: + +```v +// make buffered channels so pushing does not block (if there is room in the buffer) +ch := chan int{cap: 1} +ch2 := chan f64{cap: 1} +n := 5 +// push +ch <- n +ch2 <- 7.3 +mut y := f64(0.0) +m := <-ch // pop creating new variable +y = <-ch2 // pop into existing variable +``` + +A channel can be closed to indicate that no further objects can be pushed. Any attempt +to do so will then result in a runtime panic (with the exception of `select` and +`try_push()` - see below). Attempts to pop will return immediately if the +associated channel has been closed and the buffer is empty. This situation can be +handled using an or branch (see [Handling Optionals](#handling-optionals)). + +```v wip +ch := chan int{} +ch2 := chan f64{} +// ... +ch.close() +// ... +m := <-ch or { + println('channel has been closed') +} + +// propagate error +y := <-ch2 ? +``` + +#### Channel Select + +The `select` command allows monitoring several channels at the same time +without noticeable CPU load. It consists of a list of possible transfers and associated branches +of statements - similar to the [match](#match) command: +```v +import time + +fn main() { + ch := chan f64{} + ch2 := chan f64{} + ch3 := chan f64{} + mut b := 0.0 + c := 1.0 + // ... setup go threads that will send on ch/ch2 + go fn (the_channel chan f64) { + time.sleep(5 * time.millisecond) + the_channel <- 1.0 + }(ch) + go fn (the_channel chan f64) { + time.sleep(1 * time.millisecond) + the_channel <- 1.0 + }(ch2) + go fn (the_channel chan f64) { + _ := <-the_channel + }(ch3) + // + select { + a := <-ch { + // do something with `a` + eprintln('> a: $a') + } + b = <-ch2 { + // do something with predeclared variable `b` + eprintln('> b: $b') + } + ch3 <- c { + // do something if `c` was sent + time.sleep(5 * time.millisecond) + eprintln('> c: $c was send on channel ch3') + } + 500 * time.millisecond { + // do something if no channel has become ready within 0.5s + eprintln('> more than 0.5s passed without a channel being ready') + } + } + eprintln('> done') +} +``` + +The timeout branch is optional. If it is absent `select` waits for an unlimited amount of time. +It is also possible to proceed immediately if no channel is ready in the moment `select` is called +by adding an `else { ... }` branch. `else` and `> timeout` are mutually exclusive. + +The `select` command can be used as an *expression* of type `bool` +that becomes `false` if all channels are closed: +```v wip +if select { + ch <- a { + // ... + } +} { + // channel was open +} else { + // channel is closed +} +``` + +#### Special Channel Features + +For special purposes there are some builtin properties and methods: +```v +struct Abc { + x int +} + +a := 2.13 +ch := chan f64{} +res := ch.try_push(a) // try to perform `ch <- a` +println(res) +l := ch.len // number of elements in queue +c := ch.cap // maximum queue length +is_closed := ch.closed // bool flag - has `ch` been closed +println(l) +println(c) +mut b := Abc{} +ch2 := chan Abc{} +res2 := ch2.try_pop(mut b) // try to perform `b = <-ch2` +``` + +The `try_push/pop()` methods will return immediately with one of the results +`.success`, `.not_ready` or `.closed` - dependent on whether the object has been transferred or +the reason why not. +Usage of these methods and properties in production is not recommended - +algorithms based on them are often subject to race conditions. Especially `.len` and +`.closed` should not be used to make decisions. +Use `or` branches, error propagation or `select` instead (see [Syntax and Usage](#syntax-and-usage) +and [Channel Select](#channel-select) above). + +### Shared Objects + +Data can be exchanged between a coroutine and the calling thread via a shared variable. +Such variables should be created as `shared` and passed to the coroutine as such, too. +The underlying `struct` contains a hidden *mutex* that allows locking concurrent access +using `rlock` for read-only and `lock` for read/write access. + +```v +struct St { +mut: + x int // data to shared +} + +fn (shared b St) g() { + lock b { + // read/modify/write b.x + } +} + +fn main() { + shared a := St{ + x: 10 + } + go a.g() + // ... + rlock a { + // read a.x + } +} +``` +Shared variables must be structs, arrays or maps. + +## Decoding JSON + +```v +import json + +struct Foo { + x int +} + +struct User { + // Adding a [required] attribute will make decoding fail, if that + // field is not present in the input. + // If a field is not [required], but is missing, it will be assumed + // to have its default value, like 0 for numbers, or '' for strings, + // and decoding will not fail. + name string [required] + age int + // Use the `skip` attribute to skip certain fields + foo Foo [skip] + // If the field name is different in JSON, it can be specified + last_name string [json: lastName] +} + +data := '{ "name": "Frodo", "lastName": "Baggins", "age": 25 }' +user := json.decode(User, data) or { + eprintln('Failed to decode json, error: $err') + return +} +println(user.name) +println(user.last_name) +println(user.age) +// You can also decode JSON arrays: +sfoos := '[{"x":123},{"x":456}]' +foos := json.decode([]Foo, sfoos) ? +println(foos[0].x) +println(foos[1].x) +``` + +Because of the ubiquitous nature of JSON, support for it is built directly into V. + +The `json.decode` function takes two arguments: +the first is the type into which the JSON value should be decoded and +the second is a string containing the JSON data. + +V generates code for JSON encoding and decoding. +No runtime reflection is used. This results in much better performance. + +## Testing + +### Asserts + +```v +fn foo(mut v []int) { + v[0] = 1 +} + +mut v := [20] +foo(mut v) +assert v[0] < 4 +``` +An `assert` statement checks that its expression evaluates to `true`. If an assert fails, +the program will abort. Asserts should only be used to detect programming errors. When an +assert fails it is reported to *stderr*, and the values on each side of a comparison operator +(such as `<`, `==`) will be printed when possible. This is useful to easily find an +unexpected value. Assert statements can be used in any function. + +### Test files + +```v +// hello.v +module main + +fn hello() string { + return 'Hello world' +} + +fn main() { + println(hello()) +} +``` + +```v failcompile +module main + +// hello_test.v +fn test_hello() { + assert hello() == 'Hello world' +} +``` +To run the test above, use `v hello_test.v`. This will check that the function `hello` is +producing the correct output. V executes all test functions in the file. + +* All test functions have to be inside a test file whose name ends in `_test.v`. +* Test function names must begin with `test_` to mark them for execution. +* Normal functions can also be defined in test files, and should be called manually. Other + symbols can also be defined in test files e.g. types. +* There are two kinds of tests: external and internal. +* Internal tests must *declare* their module, just like all other .v +files from the same module. Internal tests can even call private functions in +the same module. +* External tests must *import* the modules which they test. They do not +have access to the private functions/types of the modules. They can test only +the external/public API that a module provides. + +In the example above, `test_hello` is an internal test, that can call +the private function `hello()` because `hello_test.v` has `module main`, +just like `hello.v`, i.e. both are part of the same module. Note also that +since `module main` is a regular module like the others, internal tests can +be used to test private functions in your main program .v files too. + +You can also define special test functions in a test file: +* `testsuite_begin` which will be run *before* all other test functions. +* `testsuite_end` which will be run *after* all other test functions. + +If a test function has an error return type, any propagated errors will fail the test: + +```v +import strconv + +fn test_atoi() ? { + assert strconv.atoi('1') ? == 1 + assert strconv.atoi('one') ? == 1 // test will fail +} +``` + +#### Running tests + +To run test functions in an individual test file, use `v foo_test.v`. + +To test an entire module, use `v test mymodule`. You can also use `v test .` to test +everything inside your current folder (and subfolders). You can pass the `-stats` +option to see more details about the individual tests run. + +You can put additional test data, including .v source files in a folder, named +`testdata`, right next to your _test.v files. V's test framework will *ignore* +such folders, while scanning for tests to run. This is usefull, if you want to +put .v files with invalid V source code, or other tests, including known +failing ones, that should be run in a specific way/options by a parent _test.v +file. + +NB: the path to the V compiler, is available through @VEXE, so a _test.v +file, can easily run *other* test files like this: +```v oksyntax +import os + +fn test_subtest() { + res := os.execute('${@VEXE} other_test.v') + assert res.exit_code == 1 + assert res.output.contains('other_test.v does not exist') +} +``` + +## Memory management + +V avoids doing unnecessary allocations in the first place by using value types, +string buffers, promoting a simple abstraction-free code style. + +Most objects (~90-100%) are freed by V's autofree engine: the compiler inserts +necessary free calls automatically during compilation. Remaining small percentage +of objects is freed via reference counting. + +The developer doesn't need to change anything in their code. "It just works", like in +Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for +each object. + +### Control + +You can take advantage of V's autofree engine and define a `free()` method on custom +data types: + +```v +struct MyType {} + +[unsafe] +fn (data &MyType) free() { + // ... +} +``` + +Just as the compiler frees C data types with C's `free()`, it will statically insert +`free()` calls for your data type at the end of each variable's lifetime. + +For developers willing to have more low level control, autofree can be disabled with +`-manualfree`, or by adding a `[manualfree]` on each function that wants manage its +memory manually. (See [attributes](#attributes)). + +_Note: right now autofree is hidden behind the -autofree flag. It will be enabled by +default in V 0.3. If autofree is not used, V programs will leak memory._ + +### Examples + +```v +import strings + +fn draw_text(s string, x int, y int) { + // ... +} + +fn draw_scene() { + // ... + name1 := 'abc' + name2 := 'def ghi' + draw_text('hello $name1', 10, 10) + draw_text('hello $name2', 100, 10) + draw_text(strings.repeat(`X`, 10000), 10, 50) + // ... +} +``` + +The strings don't escape `draw_text`, so they are cleaned up when +the function exits. + +In fact, with the `-prealloc` flag, the first two calls won't result in any allocations at all. +These two strings are small, so V will use a preallocated buffer for them. + +```v +struct User { + name string +} + +fn test() []int { + number := 7 // stack variable + user := User{} // struct allocated on stack + numbers := [1, 2, 3] // array allocated on heap, will be freed as the function exits + println(number) + println(user) + println(numbers) + numbers2 := [4, 5, 6] // array that's being returned, won't be freed here + return numbers2 +} +``` + +### Stack and Heap +#### Stack and Heap Basics + +Like with most other programming languages there are two locations where data can +be stored: + +* The *stack* allows fast allocations with almost zero administrative overhead. The + stack grows and shrinks with the function call depth – so every called + function has its stack segment that remains valid until the function returns. + No freeing is necessary, however, this also means that a reference to a stack + object becomes invalid on function return. Furthermore stack space is + limited (typically to a few Megabytes per thread). +* The *heap* is a large memory area (typically some Gigabytes) that is administrated + by the operating system. Heap objects are allocated and freed by special function + calls that delegate the administrative tasks to the OS. This means that they can + remain valid across several function calls, however, the administration is + expensive. + +#### V's default approach + +Due to performance considerations V tries to put objects on the stack if possible +but allocates them on the heap when obviously necessary. Example: + +```v +struct MyStruct { + n int +} + +struct RefStruct { + r &MyStruct +} + +fn main() { + q, w := f() + println('q: $q.r.n, w: $w.n') +} + +fn f() (RefStruct, &MyStruct) { + a := MyStruct{ + n: 1 + } + b := MyStruct{ + n: 2 + } + c := MyStruct{ + n: 3 + } + e := RefStruct{ + r: &b + } + x := a.n + c.n + println('x: $x') + return e, &c +} +``` + +Here `a` is stored on the stack since it's address never leaves the function `f()`. +However a reference to `b` is part of `e` which is returned. Also a reference to +`c` is returned. For this reason `b` and `c` will be heap allocated. + +Things become less obvious when a reference to an object is passed as function argument: + +```v +struct MyStruct { +mut: + n int +} + +fn main() { + mut q := MyStruct{ + n: 7 + } + w := MyStruct{ + n: 13 + } + x := q.f(&w) // references of `q` and `w` are passed + println('q: $q\nx: $x') +} + +fn (mut a MyStruct) f(b &MyStruct) int { + a.n += b.n + x := a.n * b.n + return x +} +``` +Here the call `q.f(&w)` passes references to `q` and `w` because `a` is +`mut` and `b` is of type `&MyStruct` in `f()`'s declaration, so technically +these references are leaving `main()`. However the *lifetime* of these +references lies inside the scope of `main()` so `q` and `w` are allocated +on the stack. + +#### Manual Control for Stack and Heap + +In the last example the V compiler could put `q` and `w` on the stack +because it assumed that in the call `q.f(&w)` these references were only +used for reading and modifying the referred values – and not to pass the +references themselves somewhere else. This can be seen in a way that the +references to `q` and `w` are only *borrowed* to `f()`. + +Things become different if `f()` is doing something with a reference itself: + +```v +struct RefStruct { +mut: + r &MyStruct +} + +// see discussion below +[heap] +struct MyStruct { + n int +} + +fn main() { + m := MyStruct{} + mut r := RefStruct{ + r: &m + } + r.g() + println('r: $r') +} + +fn (mut r RefStruct) g() { + s := MyStruct{ + n: 7 + } + r.f(&s) // reference to `s` inside `r` is passed back to `main() ` +} + +fn (mut r RefStruct) f(s &MyStruct) { + r.r = s // would trigger error without `[heap]` +} +``` + +Here `f()` looks quite innocent but is doing nasty things – it inserts a +reference to `s` into `r`. The problem with this is that `s` lives only as long +as `g()` is running but `r` is used in `main()` after that. For this reason +the compiler would complain about the assignment in `f()` because `s` *"might +refer to an object stored on stack"*. The assumption made in `g()` that the call +`r.f(&s)` would only borrow the reference to `s` is wrong. + +A solution to this dilemma is the `[heap]` attribute at the declaration of +`struct MyStruct`. It instructs the compiler to *always* allocate `MyStruct`-objects +on the heap. This way the reference to `s` remains valid even after `g()` returns. +The compiler takes into consideration that `MyStruct` objects are always heap +allocated when checking `f()` and allows assigning the reference to `s` to the +`r.r` field. + +There is a pattern often seen in other programming languages: + +```v failcompile +fn (mut a MyStruct) f() &MyStruct { + // do something with a + return &a // would return address of borrowed object +} +``` + +Here `f()` is passed a reference `a` as receiver that is passed back to the caller and returned +as result at the same time. The intention behind such a declaration is method chaining like +`y = x.f().g()`. However, the problem with this approach is that a second reference +to `a` is created – so it is not only borrowed and `MyStruct` has to be +declared as `[heap]`. + +In V the better approach is: + +```v +struct MyStruct { +mut: + n int +} + +fn (mut a MyStruct) f() { + // do something with `a` +} + +fn (mut a MyStruct) g() { + // do something else with `a` +} + +fn main() { + x := MyStruct{} // stack allocated + mut y := x + y.f() + y.g() + // instead of `mut y := x.f().g() +} +``` + +This way the `[heap]` attribute can be avoided – resulting in better performance. + +However, stack space is very limited as mentioned above. For this reason the `[heap]` +attribute might be suitable for very large structures even if not required by use cases +like those mentioned above. + +There is an alternative way to manually control allocation on a case to case basis. This +approach is not recommended but shown here for the sake of completeness: + +```v +struct MyStruct { + n int +} + +struct RefStruct { +mut: + r &MyStruct +} + +// simple function - just to overwrite stack segment previously used by `g()` +fn use_stack() { + x := 7.5 + y := 3.25 + z := x + y + println('$x $y $z') +} + +fn main() { + m := MyStruct{} + mut r := RefStruct{ + r: &m + } + r.g() + use_stack() // to erase invalid stack contents + println('r: $r') +} + +fn (mut r RefStruct) g() { + s := &MyStruct{ // `s` explicitly refers to a heap object + n: 7 + } + // change `&MyStruct` -> `MyStruct` above and `r.f(s)` -> `r.f(&s)` below + // to see data in stack segment being overwritten + r.f(s) +} + +fn (mut r RefStruct) f(s &MyStruct) { + r.r = unsafe { s } // override compiler check +} +``` + +Here the compiler check is suppressed by the `unsafe` block. To make `s` be heap +allocated even without `[heap]` attribute the `struct` literal is prefixed with +an ampersand: `&MyStruct{...}`. + +This last step would not be required by the compiler but without it the reference +inside `r` becomes invalid (the memory area pointed to will be overwritten by +`use_stack()`) and the program might crash (or at least produce an unpredictable +final output). That's why this approach is *unsafe* and should be avoided! + +## ORM + +(This is still in an alpha state) + +V has a built-in ORM (object-relational mapping) which supports SQLite, MySQL and Postgres, +but soon it will support MS SQL and Oracle. + +V's ORM provides a number of benefits: + +- One syntax for all SQL dialects. (Migrating between databases becomes much easier.) +- Queries are constructed using V's syntax. (There's no need to learn another syntax.) +- Safety. (All queries are automatically sanitised to prevent SQL injection.) +- Compile time checks. (This prevents typos which can only be caught during runtime.) +- Readability and simplicity. (You don't need to manually parse the results of a query and + then manually construct objects from the parsed results.) + +```v +import sqlite + +struct Customer { + // struct name has to be the same as the table name (for now) + id int [primary; sql: serial] // a field named `id` of integer type must be the first field + name string [nonull] + nr_orders int + country string [nonull] +} + +db := sqlite.connect('customers.db') ? + +// you can create tables: +// CREATE TABLE IF NOT EXISTS `Customer` ( +// `id` INTEGER PRIMARY KEY, +// `name` TEXT NOT NULL, +// `nr_orders` INTEGER, +// `country` TEXT NOT NULL +// ) +sql db { + create table Customer +} + +// select count(*) from Customer +nr_customers := sql db { + select count from Customer +} +println('number of all customers: $nr_customers') +// V syntax can be used to build queries +uk_customers := sql db { + select from Customer where country == 'uk' && nr_orders > 0 +} +println(uk_customers.len) +for customer in uk_customers { + println('$customer.id - $customer.name') +} +// by adding `limit 1` we tell V that there will be only one object +customer := sql db { + select from Customer where id == 1 limit 1 +} +println('$customer.id - $customer.name') +// insert a new customer +new_customer := Customer{ + name: 'Bob' + nr_orders: 10 +} +sql db { + insert new_customer into Customer +} +``` + +For more examples and the docs, see     vlib/orm. + +## Writing Documentation + +The way it works is very similar to Go. It's very simple: there's no need to +write documentation separately for your code, +vdoc will generate it from docstrings in the source code. + +Documentation for each function/type/const must be placed right before the declaration: + +```v +// clearall clears all bits in the array +fn clearall() { +} +``` + +The comment must start with the name of the definition. + +Sometimes one line isn't enough to explain what a function does, in that case comments should +span to the documented function using single line comments: + +```v +// copy_all recursively copies all elements of the array by their value, +// if `dupes` is false all duplicate values are eliminated in the process. +fn copy_all(dupes bool) { + // ... +} +``` + +By convention it is preferred that comments are written in *present tense*. + +An overview of the module must be placed in the first comment right after the module's name. + +To generate documentation use vdoc, for example `v doc net.http`. + +### Newlines in Documentation Comments + +Comments spanning multiple lines are merged together using spaces, unless + +- the line is empty +- the line ends with a `.` (end of sentence) +- the line is contains purely of at least 3 of `-`, `=`, `_`, `*`, `~` (horizontal rule) +- the line starts with at least one `#` followed by a space (header) +- the line starts and ends with a `|` (table) +- the line starts with `- ` (list) + +## Tools + +### v fmt + +You don't need to worry about formatting your code or setting style guidelines. +`v fmt` takes care of that: + +```shell +v fmt file.v +``` + +It's recommended to set up your editor, so that `v fmt -w` runs on every save. +A vfmt run is usually pretty cheap (takes <30ms). + +Always run `v fmt -w file.v` before pushing your code. + +### Profiling + +V has good support for profiling your programs: `v -profile profile.txt run file.v` +That will produce a profile.txt file, which you can then analyze. + +The generated profile.txt file will have lines with 4 columns: +a) how many times a function was called +b) how much time in total a function took (in ms) +c) how much time on average, a call to a function took (in ns) +d) the name of the v function + +You can sort on column 3 (average time per function) using: +`sort -n -k3 profile.txt|tail` + +You can also use stopwatches to measure just portions of your code explicitly: +```v +import time + +fn main() { + sw := time.new_stopwatch() + println('Hello world') + println('Greeting the world took: ${sw.elapsed().nanoseconds()}ns') +} +``` + +# Advanced Topics + +## Dumping expressions at runtime +You can dump/trace the value of any V expression using `dump(expr)`. +For example, save this code sample as `factorial.v`, then run it with +`v run factorial.v`: +```v +fn factorial(n u32) u32 { + if dump(n <= 1) { + return dump(1) + } + return dump(n * factorial(n - 1)) +} + +fn main() { + println(factorial(5)) +} +``` +You will get: +``` +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: true +[factorial.v:3] 1: 1 +[factorial.v:5] n * factorial(n - 1): 2 +[factorial.v:5] n * factorial(n - 1): 6 +[factorial.v:5] n * factorial(n - 1): 24 +[factorial.v:5] n * factorial(n - 1): 120 +120 +``` +Note that `dump(expr)` will trace both the source location, +the expression itself, and the expression value. + +## Memory-unsafe code + +Sometimes for efficiency you may want to write low-level code that can potentially +corrupt memory or be vulnerable to security exploits. V supports writing such code, +but not by default. + +V requires that any potentially memory-unsafe operations are marked intentionally. +Marking them also indicates to anyone reading the code that there could be +memory-safety violations if there was a mistake. + +Examples of potentially memory-unsafe operations are: + +* Pointer arithmetic +* Pointer indexing +* Conversion to pointer from an incompatible type +* Calling certain C functions, e.g. `free`, `strlen` and `strncmp`. + +To mark potentially memory-unsafe operations, enclose them in an `unsafe` block: + +```v wip +// allocate 2 uninitialized bytes & return a reference to them +mut p := unsafe { malloc(2) } +p[0] = `h` // Error: pointer indexing is only allowed in `unsafe` blocks +unsafe { + p[0] = `h` // OK + p[1] = `i` +} +p++ // Error: pointer arithmetic is only allowed in `unsafe` blocks +unsafe { + p++ // OK +} +assert *p == `i` +``` + +Best practice is to avoid putting memory-safe expressions inside an `unsafe` block, +so that the reason for using `unsafe` is as clear as possible. Generally any code +you think is memory-safe should not be inside an `unsafe` block, so the compiler +can verify it. + +If you suspect your program does violate memory-safety, you have a head start on +finding the cause: look at the `unsafe` blocks (and how they interact with +surrounding code). + +* Note: This is work in progress. + +### Structs with reference fields + +Structs with references require explicitly setting the initial value to a +reference value unless the struct already defines its own initial value. + +Zero-value references, or nil pointers, will **NOT** be supported in the future, +for now data structures such as Linked Lists or Binary Trees that rely on reference +fields that can use the value `0`, understanding that it is unsafe, and that it can +cause a panic. + +```v +struct Node { + a &Node + b &Node = 0 // Auto-initialized to nil, use with caution! +} + +// Reference fields must be initialized unless an initial value is declared. +// Zero (0) is OK but use with caution, it's a nil pointer. +foo := Node{ + a: 0 +} +bar := Node{ + a: &foo +} +baz := Node{ + a: 0 + b: 0 +} +qux := Node{ + a: &foo + b: &bar +} +println(baz) +println(qux) +``` + +## sizeof and __offsetof + +* `sizeof(Type)` gives the size of a type in bytes. +* `__offsetof(Struct, field_name)` gives the offset in bytes of a struct field. + +```v +struct Foo { + a int + b int +} + +assert sizeof(Foo) == 8 +assert __offsetof(Foo, a) == 0 +assert __offsetof(Foo, b) == 4 +``` + +## Calling C from V + +### Example + +```v +#flag -lsqlite3 +#include "sqlite3.h" +// See also the example from https://www.sqlite.org/quickstart.html +struct C.sqlite3 { +} + +struct C.sqlite3_stmt { +} + +type FnSqlite3Callback = fn (voidptr, int, &&char, &&char) int + +fn C.sqlite3_open(&char, &&C.sqlite3) int + +fn C.sqlite3_close(&C.sqlite3) int + +fn C.sqlite3_column_int(stmt &C.sqlite3_stmt, n int) int + +// ... you can also just define the type of parameter and leave out the C. prefix +fn C.sqlite3_prepare_v2(&C.sqlite3, &char, int, &&C.sqlite3_stmt, &&char) int + +fn C.sqlite3_step(&C.sqlite3_stmt) + +fn C.sqlite3_finalize(&C.sqlite3_stmt) + +fn C.sqlite3_exec(db &C.sqlite3, sql &char, cb FnSqlite3Callback, cb_arg voidptr, emsg &&char) int + +fn C.sqlite3_free(voidptr) + +fn my_callback(arg voidptr, howmany int, cvalues &&char, cnames &&char) int { + unsafe { + for i in 0 .. howmany { + print('| ${cstring_to_vstring(cnames[i])}: ${cstring_to_vstring(cvalues[i]):20} ') + } + } + println('|') + return 0 +} + +fn main() { + db := &C.sqlite3(0) // this means `sqlite3* db = 0` + // passing a string literal to a C function call results in a C string, not a V string + C.sqlite3_open(c'users.db', &db) + // C.sqlite3_open(db_path.str, &db) + query := 'select count(*) from users' + stmt := &C.sqlite3_stmt(0) + // NB: you can also use the `.str` field of a V string, + // to get its C style zero terminated representation + C.sqlite3_prepare_v2(db, &char(query.str), -1, &stmt, 0) + C.sqlite3_step(stmt) + nr_users := C.sqlite3_column_int(stmt, 0) + C.sqlite3_finalize(stmt) + println('There are $nr_users users in the database.') + // + error_msg := &char(0) + query_all_users := 'select * from users' + rc := C.sqlite3_exec(db, &char(query_all_users.str), my_callback, voidptr(7), &error_msg) + if rc != C.SQLITE_OK { + eprintln(unsafe { cstring_to_vstring(error_msg) }) + C.sqlite3_free(error_msg) + } + C.sqlite3_close(db) +} +``` + +## Calling V from C + +Since V can compile to C, calling V code from C is very easy. + +By default all V functions have the following naming scheme in C: `[module name]__[fn_name]`. + +For example, `fn foo() {}` in module `bar` will result in `bar__foo()`. + +To use a custom export name, use the `[export]` attribute: + +``` +[export: 'my_custom_c_name'] +fn foo() { +} +``` + + +## Atomics + +V has no special support for atomics, yet, nevertheless it's possible to treat variables as atomics +by calling C functions from V. The standard C11 atomic functions like `atomic_store()` are usually +defined with the help of macros and C compiler magic to provide a kind of *overloaded C functions*. +Since V does not support overloading functions by intention there are wrapper functions defined in +C headers named `atomic.h` that are part of the V compiler infrastructure. + +There are dedicated wrappers for all unsigned integer types and for pointers. +(`byte` is not fully supported on Windows) – the function names include the type name +as suffix. e.g. `C.atomic_load_ptr()` or `C.atomic_fetch_add_u64()`. + +To use these functions the C header for the used OS has to be included and the functions +that are intended to be used have to be declared.

The replacement in the opposite direction is +done exactly 10000000 times. The last replacement will be with `31` which makes the spawned +thread finish. + +It is not predictable how many replacements occur in which thread, but the sum will always +be 10000000. (With the non-atomic commands from the comments the value will be higher or the program +will hang – dependent on the compiler optimization used.) + +## Global Variables + +By default V does not allow global variables. However, in low level applications they have their +place so their usage can be enabled with the compiler flag `-enable-globals`. +Declarations of global variables must be surrounded with a `__global ( ... )` +specification – as in the example [above](#atomics). + +An initializer for global variables must be explicitly converted to the +desired target type. If no initializer is given a default initialization is done. +Some objects like semaphores and mutexes require an explicit initialization *in place*, i.e. +not with a value returned from a function call but with a method call by reference. +A separate `init()` function can be used for this purpose – it will be called before `main()`: + +```v globals +import sync + +__global ( + sem sync.Semaphore // needs initialization in `init()` + mtx sync.RwMutex // needs initialization in `init()` + f1 = f64(34.0625) // explicily initialized + shmap shared map[string]f64 // initialized as empty `shared` map + f2 f64 // initialized to `0.0` +) + +fn init() { + sem.init(0) + mtx.init() +} +``` +Be aware that in multi threaded applications the access to global variables is subject +to race conditions. There are several approaches to deal with these: + +- use `shared` types for the variable declarations and use `lock` blocks for access. + This is most appropriate for larger objects like structs, arrays or maps. +- handle primitive data types as "atomics" using special C-functions (see [above](#atomics)). +- use explicit synchronization primitives like mutexes to control access. The compiler + cannot really help in this case, so you have to know what you are doing. +- don't care – this approach is possible but makes only sense if the exact values + of global variables do not really matter. An example can be found in the `rand` module + where global variables are used to generate (non cryptographic) pseudo random numbers. + In this case data races lead to random numbers in different threads becoming somewhat + correlated, which is acceptable considering the performance penalty that using + synchonization primitives would represent. + +### Passing C compilation flags + +Add `#flag` directives to the top of your V files to provide C compilation flags like: + +- `-I` for adding C include files search paths +- `-l` for adding C library names that you want to get linked +- `-L` for adding C library files search paths +- `-D` for setting compile time variables + +You can (optionally) use different flags for different targets. +Currently the `linux`, `darwin` , `freebsd`, and `windows` flags are supported. + +NB: Each flag must go on its own line (for now) + +```v oksyntax +#flag linux -lsdl2 +#flag linux -Ivig +#flag linux -DCIMGUI_DEFINE_ENUMS_AND_STRUCTS=1 +#flag linux -DIMGUI_DISABLE_OBSOLETE_FUNCTIONS=1 +#flag linux -DIMGUI_IMPL_API= +``` + +In the console build command, you can use: +* `-cflags` to pass custom flags to the backend C compiler. +* `-cc` to change the default C backend compiler. +* For example: `-cc gcc-9 -cflags -fsanitize=thread`. + +You can define a `VFLAGS` environment variable in your terminal to store your `-cc` +and `-cflags` settings, rather than including them in the build command each time. + +### #pkgconfig + +Add `#pkgconfig` directive is used to tell the compiler which modules should be used for compiling +and linking using the pkg-config files provided by the respective dependencies. + +As long as backticks can't be used in `#flag` and spawning processes is not desirable for security +and portability reasons, V uses its own pkgconfig library that is compatible with the standard +freedesktop one. + +If no flags are passed it will add `--cflags` and `--libs`, both lines below do the same: + +```v oksyntax +#pkgconfig r_core +#pkgconfig --cflags --libs r_core +``` + +The `.pc` files are looked up into a hardcoded list of default pkg-config paths, the user can add +extra paths by using the `PKG_CONFIG_PATH` environment variable. Multiple modules can be passed. + +To check the existance of a pkg-config use `$pkgconfig('pkg')` as a compile time if condition to +check if a pkg-config exists. If it exists the branch will be created. Use `$else` or `$else $if` +to handle other cases. + +```v ignore +$if $pkgconfig('mysqlclient') { + #pkgconfig mysqlclient +} $else $if $pkgconfig('mariadb') { + #pkgconfig mariadb +} +``` + +### Including C code + +You can also include C code directly in your V module. +For example, let's say that your C code is located in a folder named 'c' inside your module folder. +Then: + +* Put a v.mod file inside the toplevel folder of your module (if you +created your module with `v new` you already have v.mod file). For +example: +```v ignore +Module { + name: 'mymodule', + description: 'My nice module wraps a simple C library.', + version: '0.0.1' + dependencies: [] +} +``` + + +* Add these lines to the top of your module: +```v oksyntax +#flag -I @VMODROOT/c +#flag @VMODROOT/c/implementation.o +#include "header.h" +``` +NB: @VMODROOT will be replaced by V with the *nearest parent folder, where there is a v.mod file*. +Any .v file beside or below the folder where the v.mod file is, +can use `#flag @VMODROOT/abc` to refer to this folder. +The @VMODROOT folder is also *prepended* to the module lookup path, +so you can *import* other modules under your @VMODROOT, by just naming them. + +The instructions above will make V look for an compiled .o file in +your module `folder/c/implementation.o`. +If V finds it, the .o file will get linked to the main executable, that used the module. +If it does not find it, V assumes that there is a `@VMODROOT/c/implementation.c` file, +and tries to compile it to a .o file, then will use that. + +This allows you to have C code, that is contained in a V module, so that its distribution is easier. +You can see a complete minimal example for using C code in a V wrapper module here: +[project_with_c_code](https://github.com/vlang/v/tree/master/vlib/v/tests/project_with_c_code). +Another example, demonstrating passing structs from C to V and back again: +[interoperate between C to V to C](https://github.com/vlang/v/tree/master/vlib/v/tests/project_with_c_code_2). + +### C types + +Ordinary zero terminated C strings can be converted to V strings with +`unsafe { &char(cstring).vstring() }` or if you know their length already with +`unsafe { &char(cstring).vstring_with_len(len) }`. + +NB: The .vstring() and .vstring_with_len() methods do NOT create a copy of the `cstring`, +so you should NOT free it after calling the method `.vstring()`. +If you need to make a copy of the C string (some libc APIs like `getenv` pretty much require that, +since they return pointers to internal libc memory), you can use `cstring_to_vstring(cstring)`. + +On Windows, C APIs often return so called `wide` strings (utf16 encoding). +These can be converted to V strings with `string_from_wide(&u16(cwidestring))` . + +V has these types for easier interoperability with C: + +- `voidptr` for C's `void*`, +- `&byte` for C's `byte*` and +- `&char` for C's `char*`. +- `&&char` for C's `char**` + +To cast a `voidptr` to a V reference, use `user := &User(user_void_ptr)`. + +`voidptr` can also be dereferenced into a V struct through casting: `user := User(user_void_ptr)`. + +[an example of a module that calls C code from V](https://github.com/vlang/v/blob/master/vlib/v/tests/project_with_c_code/mod1/wrapper.v) + +### C Declarations + +C identifiers are accessed with the `C` prefix similarly to how module-specific +identifiers are accessed. Functions must be redeclared in V before they can be used. +Any C types may be used behind the `C` prefix, but types must be redeclared in V in +order to access type members. + +To redeclare complex types, such as in the following C code: + +```c +struct SomeCStruct { + uint8_t implTraits; + uint16_t memPoolData; + union { + struct { + void* data; + size_t size; + }; + + DataView view; + }; +}; +``` + +members of sub-data-structures may be directly declared in the containing struct as below: + +```v +struct C.SomeCStruct { + implTraits byte + memPoolData u16 + // These members are part of sub data structures that can't currently be represented in V. + // Declaring them directly like this is sufficient for access. + // union { + // struct { + data voidptr + size size_t + // } + view C.DataView + // } +} +``` + +The existence of the data members is made known to V, and they may be used without +re-creating the original structure exactly. + +Alternatively, you may [embed](#embedded-structs) the sub-data-structures to maintain +a parallel code structure. + +## Debugging + +### C Backend binaries (Default) + +To debug issues in the generated binary (flag: `-b c`), you can pass these flags: + +- `-g` - produces a less optimized executable with more debug information in it. + V will enforce line numbers from the .v files in the stacktraces, that the + executable will produce on panic. It is usually better to pass -g, unless + you are writing low level code, in which case use the next option `-cg`. +- `-cg` - produces a less optimized executable with more debug information in it. + The executable will use C source line numbers in this case. It is frequently + used in combination with `-keepc`, so that you can inspect the generated + C program in case of panic, or so that your debugger (`gdb`, `lldb` etc.) + can show you the generated C source code. +- `-showcc` - prints the C command that is used to build the program. +- `-show-c-output` - prints the output, that your C compiler produced + while compiling your program. +- `-keepc` - do not delete the generated C source code file after a successful + compilation. Also keep using the same file path, so it is more stable, + and easier to keep opened in an editor/IDE. + +For best debugging experience if you are writing a low level wrapper for an existing +C library, you can pass several of these flags at the same time: +`v -keepc -cg -showcc yourprogram.v`, then just run your debugger (gdb/lldb) or IDE +on the produced executable `yourprogram`. + +If you just want to inspect the generated C code, +without further compilation, you can also use the `-o` flag (e.g. `-o file.c`). +This will make V produce the `file.c` then stop. + +If you want to see the generated C source code for *just* a single C function, +for example `main`, you can use: `-printfn main -o file.c`. + +To debug the V executable itself you need to compile from src with `./v -g -o v cmd/v`. + +You can debug tests with for example `v -g -keepc prog_test.v`. The `-keepc` flag is needed, +so that the executable is not deleted, after it was created and ran. + +To see a detailed list of all flags that V supports, +use `v help`, `v help build` and `v help build-c`. + +**Commandline Debugging** + +1. compile your binary with debugging info `v -g hello.v` +2. debug with [lldb](https://lldb.llvm.org) or [GDB](https://www.gnu.org/software/gdb/) e.g. `lldb hello` + +Troubleshooting (debugging) executables [created with V in GDB](https://github.com/vlang/v/wiki/Troubleshooting-(debugging)-executables-created-with-V-in-GDB) + +**Visual debugging Setup:** +* [Visual Studio Code](vscode.md) + +### Native Backend binaries + +Currently there is no debugging support for binaries, created by the +native backend (flag: `-b native`). + +### Javascript Backend + +To debug the generated Javascript output you can active source maps: +`v -b js -sourcemap hello.v -o hello.js` + +For all supported options check the latest help: +`v help build-js` + +## Conditional compilation + +### Compile time code + +`$` is used as a prefix for compile-time operations. + +#### `$if` condition +```v +// Support for multiple conditions in one branch +$if ios || android { + println('Running on a mobile device!') +} +$if linux && x64 { + println('64-bit Linux.') +} +// Usage as expression +os := $if windows { 'Windows' } $else { 'UNIX' } +println('Using $os') +// $else-$if branches +$if tinyc { + println('tinyc') +} $else $if clang { + println('clang') +} $else $if gcc { + println('gcc') +} $else { + println('different compiler') +} +$if test { + println('testing') +} +// v -cg ... +$if debug { + println('debugging') +} +// v -prod ... +$if prod { + println('production build') +} +// v -d option ... +$if option ? { + println('custom option') +} +``` + +If you want an `if` to be evaluated at compile time it must be prefixed with a `$` sign. +Right now it can be used to detect an OS, compiler, platform or compilation options. +`$if debug` is a special option like `$if windows` or `$if x32`. +If you're using a custom ifdef, then you do need `$if option ? {}` and compile with`v -d option`. +Full list of builtin options: +| OS | Compilers | Platforms | Other | +| --- | --- | --- | --- | +| `windows`, `linux`, `macos` | `gcc`, `tinyc` | `amd64`, `arm64` | `debug`, `prod`, `test` | +| `mac`, `darwin`, `ios`, | `clang`, `mingw` | `x64`, `x32` | `js`, `glibc`, `prealloc` | +| `android`,`mach`, `dragonfly` | `msvc` | `little_endian` | `no_bounds_checking`, `freestanding` | +| `gnu`, `hpux`, `haiku`, `qnx` | `cplusplus` | `big_endian` | +| `solaris` | | | | + +#### `$embed_file` + +```v ignore +import os +fn main() { + embedded_file := $embed_file('v.png') + os.write_file('exported.png', embedded_file.to_string()) ? +} +``` + +V can embed arbitrary files into the executable with the `$embed_file()` +compile time call. Paths can be absolute or relative to the source file. + +When you do not use `-prod`, the file will not be embedded. Instead, it will +be loaded *the first time* your program calls `f.data()` at runtime, making +it easier to change in external editor programs, without needing to recompile +your executable. + +When you compile with `-prod`, the file *will be embedded inside* your +executable, increasing your binary size, but making it more self contained +and thus easier to distribute.

These files can contain JS. code. +- `.c.v` => will be used only by the C backend. These files can contain C. code. +- `.native.v` => will be used only by V's native backend. +- `_nix.c.v` => will be used only on Unix systems (non Windows). +- `_${os}.c.v` => will be used only on the specific `os` system. +For example, `_windows.c.v` will be used only when compiling on Windows, or with `-os windows`. +- `_default.c.v` => will be used only if there is NOT a more specific platform file. +For example, if you have both `file_linux.c.v` and `file_default.c.v`, +and you are compiling for linux, then only `file_linux.c.v` will be used, +and `file_default.c.v` will be ignored. + +Here is a more complete example: +main.v: +```v ignore +module main +fn main() { println(message) } +``` + +main_default.c.v: +```v ignore +module main +const ( message = 'Hello world' ) +``` + +main_linux.c.v: +```v ignore +module main +const ( message = 'Hello linux' ) +``` + +main_windows.c.v: +```v ignore +module main +const ( message = 'Hello windows' ) +``` + +With the example above: +- when you compile for windows, you will get 'Hello windows' +- when you compile for linux, you will get 'Hello linux' +- when you compile for any other platform, you will get the +non specific 'Hello world' message. + +- `_d_customflag.v` => will be used *only* if you pass `-d customflag` to V. +That corresponds to `$if customflag ? {}`, but for a whole file, not just a +single block. `customflag` should be a snake_case identifier, it can not +contain arbitrary characters (only lower case latin letters + numbers + `_`). +NB: a combinatorial `_d_customflag_linux.c.v` postfix will not work. +If you do need a custom flag file, that has platform dependent code, use the +postfix `_d_customflag.v`, and then use plaftorm dependent compile time +conditional blocks inside it, i.e. `$if linux {}` etc. + +- `_notd_customflag.v` => similar to _d_customflag.v, but will be used +*only* if you do NOT pass `-d customflag` to V. + +## Compile time pseudo variables + +V also gives your code access to a set of pseudo string variables, +that are substituted at compile time: + +- `@FN` => replaced with the name of the current V function +- `@METHOD` => replaced with ReceiverType.MethodName +- `@MOD` => replaced with the name of the current V module +- `@STRUCT` => replaced with the name of the current V struct +- `@FILE` => replaced with the path of the V source file +- `@LINE` => replaced with the V line number where it appears (as a string). +- `@COLUMN` => replaced with the column where it appears (as a string). +- `@VEXE` => replaced with the path to the V compiler +- `@VEXEROOT` => will be substituted with the *folder*, + where the V executable is (as a string). +- `@VHASH` => replaced with the shortened commit hash of the V compiler (as a string). +- `@VMOD_FILE` => replaced with the contents of the nearest v.mod file (as a string). +- `@VMODROOT` => will be substituted with the *folder*, + where the nearest v.mod file is (as a string). + +That allows you to do the following example, useful while debugging/logging/tracing your code: +```v +eprintln('file: ' + @FILE + ' | line: ' + @LINE + ' | fn: ' + @MOD + '.' + @FN) +``` + +Another example, is if you want to embed the version/name from v.mod *inside* your executable: +```v ignore +import v.vmod +vm := vmod.decode( @VMOD_FILE ) or { panic(err.msg) } +eprintln('$vm.name $vm.version\n $vm.description') +``` + +## Performance tuning + +The generated C code is usually fast enough, when you compile your code +with `-prod`. There are some situations though, where you may want to give +additional hints to the compiler, so that it can further optimize some +blocks of code. + +NB: These are *rarely* needed, and should not be used, unless you +*profile your code*, and then see that there are significant benefits for them. +To cite gcc's documentation: "programmers are notoriously bad at predicting +how their programs actually perform". + +`[inline]` - you can tag functions with `[inline]`, so the C compiler will +try to inline them, which in some cases, may be beneficial for performance, +but may impact the size of your executable. + +`[direct_array_access]` - in functions tagged with `[direct_array_access]` +the compiler will translate array operations directly into C array operations - +omiting bounds checking. This may save a lot of time in a function that iterates +over an array but at the cost of making the function unsafe - unless +the boundaries will be checked by the user. + +`if _likely_(bool expression) {` this hints the C compiler, that the passed +boolean expression is very likely to be true, so it can generate assembly +code, with less chance of branch misprediction. In the JS backend, +that does nothing. + +`if _unlikely_(bool expression) {` similar to `_likely_(x)`, but it hints that +the boolean expression is highly improbable. In the JS backend, that does nothing. + + + +## Compile-time reflection + +Having built-in JSON support is nice, but V also allows you to create efficient +serializers for any data format. V has compile-time `if` and `for` constructs: + +```v wip +// TODO: not fully implemented + +struct User { + name string + age int +} + +// Note: T should be passed a struct name only +fn decode(data string) T { + mut result := T{} + // compile-time `for` loop + // T.fields gives an array of a field metadata type + $for field in T.fields { + $if field.typ is string { + // $(string_expr) produces an identifier + result.$(field.name) = get_string(data, field.name) + } $else $if field.typ is int { + result.$(field.name) = get_int(data, field.name) + } + } + return result +} + +// `decode` generates: +fn decode_User(data string) User { + mut result := User{} + result.name = get_string(data, 'name') + result.age = get_int(data, 'age') + return result +} +``` + +## Limited operator overloading + +```v +struct Vec { + x int + y int +} + +fn (a Vec) str() string { + return '{$a.x, $a.y}' +} + +fn (a Vec) + (b Vec) Vec { + return Vec{a.x + b.x, a.y + b.y} +} + +fn (a Vec) - (b Vec) Vec { + return Vec{a.x - b.x, a.y - b.y} +} + +fn main() { + a := Vec{2, 3} + b := Vec{4, 5} + mut c := Vec{1, 2} + println(a + b) // "{6, 8}" + println(a - b) // "{-2, -2}" + c += a + println(c) // "{3, 5}" +} +``` + +Operator overloading goes against V's philosophy of simplicity and predictability. +But since scientific and graphical applications are among V's domains, +operator overloading is an important feature to have in order to improve readability: + +`a.add(b).add(c.mul(d))` is a lot less readable than `a + b + c * d`. + +To improve safety and maintainability, operator overloading is limited: + +- It's only possible to overload `+, -, *, /, %, <, >, ==, !=, <=, >=` operators. +- `==` and `!=` are self generated by the compiler but can be overriden. +- Calling other functions inside operator functions is not allowed. +- Operator functions can't modify their arguments. +- When using `<` and `==` operators, the return type must be `bool`. +- `!=`, `>`, `<=` and `>=` are auto generated when `==` and `<` are defined. +- Both arguments must have the same type (just like with all operators in V). +- Assignment operators (`*=`, `+=`, `/=`, etc) +are auto generated when the operators are defined though they must return the same type. + +## Inline assembly + +```v ignore +a := 100 +b := 20 +mut c := 0 +asm amd64 { + mov eax, a + add eax, b + mov c, eax + ; =r (c) as c // output + ; r (a) as a // input + r (b) as b +} +println('a: $a') // 100 +println('b: $b') // 20 +println('c: $c') // 120 +``` + +For more examples, see [github.com/vlang/v/tree/master/vlib/v/tests/assembly/asm_test.amd64.v](https://github.com/vlang/v/tree/master/vlib/v/tests/assembly/asm_test.amd64.v) + +## Translating C to V + +TODO: translating C to V will be available in V 0.3. + +V can translate your C code to human readable V code and generate V wrappers on top of C libraries. + + +Let's create a simple program `test.c` first: + +```c +#include "stdio.h" + +int main() { + for (int i = 0; i < 10; i++) { + printf("hello world\n"); + } + return 0; +} +``` + +Run `v translate test.c`, and V will generate `test.v`: + +```v +fn main() { + for i := 0; i < 10; i++ { + println('hello world') + } +} +``` + +To generate a wrapper on top of a C library use this command: + +```bash +v wrapper c_code/libsodium/src/libsodium +``` + +This will generate a directory `libsodium` with a V module. + +Example of a C2V generated libsodium wrapper: + +https://github.com/medvednikov/libsodium + +
    + +When should you translate C code and when should you simply call C code from V? + +If you have well-written, well-tested C code, +then of course you can always simply call this C code from V. + +Translating it to V gives you several advantages: + +- If you plan to develop that code base, you now have everything in one language, + which is much safer and easier to develop in than C. +- Cross-compilation becomes a lot easier.

Once the counter reaches 0 the object is automatically freed. +3 Since an `atomic` variable is only a few bytes in size +allocation would be an unnecessary overhead. Instead the compiler +creates a global. + +### Compatibility +Outside of `lock`/`rlock` blocks function arguments must in general +match - with the familiar exception that objects declared `mut` can be +used to call functions expecting immutable arguments: + +```v ignore +fn f(x St) {...} +fn g(mut x St) {...} +fn h(shared x St) {...} +fn i(atomic x u64) {...} + +a := St{...} +f(a) + +mut b := St{...} +f(b) +go g(mut b) +// `b` should not be accessed here any more + +shared c := St{...} +h(shared c) + +atomic d &u64 +i(atomic d) +``` + +Inside a `lock c {...}` block `c` behaves like a `mut`, +inside an `rlock c {...}` block like an immutable: +```v ignore +shared c := St{...} +lock c { + g(mut c) + f(c) + // call to h() not allowed inside `lock` block + // since h() will lock `c` itself +} +rlock c { + f(c) + // call to g() or h() not allowed +} +``` + +### Automatic Lock +In general the compiler will generate an error message when a `shared` +object is accessed outside of any corresponding `lock`/`rlock` +block. However in simple and obvious cases the necessary lock/unlock +can be generated automatically for `array`/`map` operations: + +```v ignore +shared a := []int{cap: 5} +go h2(shared a) +a << 3 +// keep in mind that `h2()` could change `a` between these statements +a << 4 +x := a[1] // not necessarily `4` + +shared b := map[string]int{} +go h3(shared b) +b['apple'] = 3 +c['plume'] = 7 +y := b['apple'] // not necesarily `3` + +// iteration over elements +for k, v in b { + // concurrently changed k/v pairs may or my not be included +} +``` + +This is handy, but since other coroutines might access the `array`/`map` +concurrently between the automatically locked statements, the results +are sometimes surprising. Each statement should be seen as a single +transaction that is unrelated to the previous or following +statement. Therefore - but also for performance reasons - it's often +better to group consecutive coherent statements in an explicit `lock` block. + +### Channels diff --git a/v_windows/v/doc/vscode.md b/v_windows/v/doc/vscode.md new file mode 100644 index 0000000..e1e1b35 --- /dev/null +++ b/v_windows/v/doc/vscode.md @@ -0,0 +1,107 @@ +# Visual Studio Code Setup + +## Table of Contents + +* [V language support](#v-language-support) +* [Visual Debugging](#visual-debugging) + +## V language support + +The [V VS Code Extention](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang) +provides V language support for Visual Studio Code. + +![Screenshot Code with activated extention](https://github.com/vlang/vscode-vlang/raw/HEAD/images/demo.png) + +**Features:** +* Syntax Highlighting. +* Code Snippets for quick coding. +* Format code on file save as well as format manually (using v fmt). +* Linter (Workspace files only). +[more](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang) + +**Hint:** This extention will not add the V compiler!

+Once upon a midnight dreary, while I pondered, weak and weary, +Over many a quaint and curious volume of forgotten lore— + While I nodded, nearly napping, suddenly there came a tapping, +As of some

terrors never felt before; + So that now, to still the beating of my heart, I stood repeating + “’Tis some visitor entreating entrance at my chamber door— +Some late visitor entreating entrance at my chamber door;— + This it is and nothing more.” + + Presently my soul grew stronger; hesitating then no longer, +“Sir,” said I, “or Madam, truly your forgiveness I implore; + But the fact is I was napping, and so gently you came rapping, + And so faintly you came tapping, tapping at my chamber door, +That I scarce was sure I heard you”—here I opened wide the door;— + Darkness there and nothing more. + +Deep into that darkness peering, long I stood there wondering, fearing, +Doubting, dreaming dreams no mortal ever dared to dream before; + But the silence was unbroken, and the stillness gave no token, + And the only word there spoken was the whispered word, “Lenore?” +This I whispered, and an echo murmured back the word, “Lenore!”— + Merely this and nothing more. + + Back into the chamber turning, all my soul within me burning, +Soon again I heard a tapping somewhat louder than before. + “Surely,” said I, “surely that is something at my window lattice; + Let me see, then, what thereat

With this she closed her eyes and died. + +The girl went out to her mother's grave every day and wept, and she remained +pious and good. When winter came the snow spread a white cloth over the grave, +and when the spring sun had removed it again, the man took himself another +wife. + +This wife brought two daughters into the house with her. They were beautiful, +with fair faces, but evil and dark hearts. Times soon grew very bad for the +poor stepchild. + +"Why should that stupid goose sit in the parlor with us?" they said. "If she +wants to eat bread, then she will have to earn it. Out with this kitchen maid!" + +They took her beautiful clothes away from her, dressed her in an old gray +smock, and gave her wooden shoes. "Just look at the proud princess! How decked +out she is!" they shouted and laughed as they led her into the kitchen. + +There she had to do hard work from morning until evening, get up before +daybreak, carry water, make the fires, cook, and wash. Besides this, the +sisters did everything imaginable to hurt her. They made fun of her, scattered +peas and lentils into the ashes for her, so that she had to sit and pick them +out again. In the evening when she had worked herself weary, there was no bed +for her. Instead she had to sleep by the hearth in the ashes. And because she +always looked dusty and dirty, they called her Cinderella. + +One day it happened that the father was going to the fair, and he asked his two +stepdaughters what he should bring back for them. + +"Beautiful dresses," said the one. + +"Pearls and jewels," said the other. + +"And you, Cinderella," he said, "what do you want?" + +"Father, break off for me the first twig that brushes against your hat on your +way home." + +So he bought beautiful dresses, pearls, and jewels for his two stepdaughters. +On his way home, as he was riding through a green thicket, a hazel twig brushed +against him and knocked off his hat. Then he broke off the twig and took it +with him. Arriving home, he gave his stepdaughters the things that they had +asked for, and he gave Cinderella the twig from the hazel bush. + +Cinderella thanked him, went to her mother's grave, and planted the branch on +it, and she wept so much that her tears fell upon it and watered it. It grew +and became a beautiful tree. + +Cinderella went to this tree three times every day, and beneath it she wept and +prayed. A white bird came to the tree every time, and whenever she expressed a +wish, the bird would throw down to her what she had wished for. + +Now it happened that the king proclaimed a festival that was to last three +days. All the beautiful young girls in the land were invited, so that his son +could select a bride for himself. When the two stepsisters heard that they too +had been invited, they were in high spirits. + +They called Cinderella, saying, "Comb our hair for us. Brush our shoes and +fasten our buckles. We are going to the festival at the king's castle." + +Cinderella obeyed, but wept, because she too would have liked to go to the +dance with them. She begged her stepmother to allow her to go. + +"You, Cinderella?" she said. "You, all covered with dust and dirt, and you want +to go to the festival?. You have neither clothes nor shoes, and yet you want to +dance!" + +However, because Cinderella kept asking, the stepmother finally said, "I have +scattered a bowl of lentils into the ashes for you. If you can pick them out +again in two hours, then you may go with us." + +The girl went through the back door into the garden, and called out, "You tame +pigeons, you turtledoves, and all you birds beneath the sky, come and help me +to gather: + +The good ones go into the pot, The bad ones go into your crop." Two white +pigeons came in through the kitchen window, and then the turtledoves, and +finally all the birds beneath the sky came whirring and swarming in, and lit +around the ashes. The pigeons nodded their heads and began to pick, pick, pick, +pick. And the others also began to pick, pick, pick, pick. They gathered all +the good grains into the bowl. Hardly one hour had passed before they were +finished, and they all flew out again. The girl took the bowl to her +stepmother, and was happy, thinking that now she would be allowed to go to the +festival with them. + +But the stepmother said, "No, Cinderella, you have no clothes, and you don't +know how to dance. Everyone would only laugh at you." + +Cinderella began to cry, and then the stepmother said, "You may go if you are +able to pick two bowls of lentils out of the ashes for me in one hour," +thinking to herself, "She will never be able to do that." + +The girl went through the back door into the garden, and called out, "You tame +pigeons, you turtledoves, and all you birds beneath the sky, come and help me +to gather: + +The good ones go into the pot, The bad ones go into your crop."

The pigeons nodded their heads and began to pick, pick, pick, +pick. And the others also began to pick, pick, pick, pick. They gathered all +the good grains into the bowls. Before a half hour had passed they were +finished, and they all flew out again. The girl took the bowls to her +stepmother, and was happy, thinking that now she would be allowed to go to the +festival with them. + +But the stepmother said, "It's no use. You are not coming with us, for you have +no clothes, and you don't know how to dance. We would be ashamed of you." With +this she turned her back on Cinderella, and hurried away with her two proud +daughters. + +Now that no one else was at home, Cinderella went to her mother's grave beneath +the hazel tree, and cried out: + +Shake and quiver, little tree, Throw gold and silver down to me. Then the bird +threw a gold and silver dress down to her, and slippers embroidered with silk +and silver. She quickly put on the dress and went to the festival. Her +stepsisters and her stepmother did not recognize her. They thought she must be +a foreign princess, for she looked so beautiful in the golden dress. They never +once thought it was Cinderella, for they thought that she was sitting at home +in the dirt, looking for lentils in the ashes. + +The prince approached her, took her by the hand, and danced with her. +Furthermore, he would dance with no one else. He never let go of her hand, and +whenever anyone else came and asked her to dance, he would say, "She is my +dance partner." + +She danced until evening, and then she wanted to go home. But the prince said, +"I will go along and escort you," for he wanted to see to whom the beautiful +girl belonged. However, she eluded him and jumped into the pigeon coop. The +prince waited until her father came, and then he told him that the unknown girl +had jumped into the pigeon coop. + +The old man thought, "Could it be Cinderella?" + +He had them bring him an ax and a pick so that he could break the pigeon coop +apart, but no one was inside. When they got home Cinderella was lying in the +ashes, dressed in her dirty clothes. A dim little oil-lamp was burning in the +fireplace. Cinderella had quickly jumped down from the back of the pigeon coop +and had run to the hazel tree. There she had taken off her beautiful clothes +and laid them on the grave, and the bird had taken them away again. Then, +dressed in her gray smock, she had returned to the ashes in the kitchen. + +The next day when the festival began anew, and her parents and her stepsisters +had gone again, Cinderella went to the hazel tree and said: + +Shake and quiver, little tree, Throw gold and silver down to me. Then the bird +threw down an even more magnificent dress than on the preceding day. When +Cinderella appeared at the festival in this dress, everyone was astonished at +her beauty. The prince had waited until she came, then immediately took her by +the hand, and danced only with her. When others came and asked her to dance +with them, he said, "She is my dance partner." When evening came she wanted to +leave, and the prince followed her, wanting to see into which house she went. +But she ran away from him and into the garden behind the house. A beautiful +tall tree stood there, on which hung the most magnificent pears. She climbed as +nimbly as a squirrel into the branches, and the prince did not know where she +had gone. He waited until her father came, then said to him, "The unknown girl +has eluded me, and I believe she has climbed up the pear tree. + +The father thought, "Could it be Cinderella?" He had an ax brought to him and +cut down the tree, but no one was in it. When they came to the kitchen, +Cinderella was lying there in the ashes as usual, for she had jumped down from +the other side of the tree, had taken the beautiful dress back to the bird in +the hazel tree, and had put on her gray smock. + +On the third day, when her parents and sisters had gone away, Cinderella went +again to her mother's grave and said to the tree: + +Shake and quiver, little tree, Throw gold and silver down to me. This time the +bird threw down to her a dress that was more splendid and magnificent than any +she had yet had, and the slippers were of pure gold. When she arrived at the +festival in this dress, everyone was so astonished that they did not know what +to say. The prince danced only with her, and whenever anyone else asked her to +dance, he would say, "She is my dance partner." When evening came Cinderella +wanted to leave, and the prince tried to escort her, but she ran away from him +so quickly that he could not follow her. The prince, however, had set a trap. +He had had the entire stairway smeared with pitch. When she ran down the +stairs, her left slipper stuck in the pitch. The prince picked it up. It was +small and dainty, and of pure gold. + +The next morning, he went with it to the man, and said to him, "No one shall be +my wife except for the one whose foot fits this golden shoe." + +The two sisters were happy to hear this, for they had pretty feet. With her +mother standing by, the older one took the shoe into her bedroom to try it on. +She could not get her big toe into it, for the shoe was too small for her. Then +her mother gave her a knife and said, "Cut off your toe. When you are queen you +will no longer have to go on foot." + +The girl cut off her toe, forced her foot into the shoe, swallowed the pain, +and went out to the prince. He took her on his horse as his bride and rode away +with her. However, they had to ride past the grave, and there, on the hazel +tree, sat the two pigeons, crying out: + +Rook di goo, rook di goo! There's blood in the shoe. The shoe is too tight, +This bride is not right! Then he looked at her foot and saw how the blood was +running from it. He turned his horse around and took the false bride home +again, saying that she was not the right one, and that the other sister should +try on the shoe. She went into her bedroom, and got her toes into the shoe all +right, but her heel was too large. Then her mother gave her a knife, and said, +"Cut a piece off your heel. When you are queen you will no longer have to go on +foot." + +The girl cut a piece off her heel, forced her foot into the shoe, swallowed the +pain, and went out to the prince. He took her on his horse as his bride and +rode away with her. When they passed the hazel tree, the two pigeons were +sitting in it, and they cried out: + +Rook di goo, rook di goo! There's blood in the shoe. The shoe is too tight, +This bride is not right! He looked down at her foot and saw how the blood was +running out of her shoe, and how it had stained her white stocking all red. +Then he turned his horse around and took the false bride home again. "This is +not the right one, either," he said. "Don't you have another daughter?" + +"No," said the man. "There is only a deformed little Cinderella from my first +wife, but she cannot possibly be the bride." + +The prince told him to send her to him, but the mother answered, "Oh, no, she +is much too dirty. She cannot be seen." + +But the prince insisted on it, and they had to call Cinderella. She first +washed her hands and face clean, and then went and bowed down before the +prince, who gave her the golden shoe. She sat down on a stool, pulled her foot +out of the heavy wooden shoe, and put it into the slipper, and it fitted her +perfectly. + +When she stood up the prince looked into her face, and he recognized the +beautiful girl who had danced with him. He cried out, "She is my true bride." + +The stepmother and the two sisters were horrified and turned pale with anger. +The prince, however, took Cinderella onto his horse and rode away with her. As +they passed by the hazel tree, the two white pigeons cried out: + +Rook di goo, rook di goo! No blood's in the shoe. The shoe's not too tight, +This bride is right! After they had cried this out, they both flew down and +lit on Cinderella's shoulders, one on the right, the other on the left, and +remained sitting there. When the wedding with the prince was to be held, the +two false sisters came, wanting to gain favor with Cinderella and to share her +good fortune. When the bridal couple walked into the church, the older sister +walked on their right side and the younger on their left side, and the pigeons +pecked out one eye from each of them. Afterwards, as they came out of the +church, the older one was on the left side, and the younger one on the right +side, and then the pigeons pecked out the other eye from each of them. And +thus, for their wickedness and falsehood, they were punished with blindness as +long as they lived. + + diff --git a/v_windows/v/examples/word_counter/word_counter.v b/v_windows/v/examples/word_counter/word_counter.v new file mode 100644 index 0000000..fc60a6f --- /dev/null +++ b/v_windows/v/examples/word_counter/word_counter.v @@ -0,0 +1,70 @@ +// Copyright (c) 2019-2021 Alexander Medvednikov.

One of V's goals is to be open to developers with different levels +of experience in compiler development. Compilers don't need to be black boxes +full of magic that only few people understand. + +The V compiler is modular, and can be used by other applications. It is located +in `cmd/v/` and `vlib/v/`. + +The most important and useful command to remember when working on the V compiler +is `v self`. +It rebuilds the V compiler. + +Be careful, if you introduce a breaking change and rebuild V, you will no longer +be able to use V to build itself. So it's a good idea to make a backup copy of a +working compiler executable. + +But don't worry, you can always simply run `make` (or `make.bat`), it will +download the C version of the compiler and rebuild it from scratch. + +The architecture of the compiler is very simple and has three distinct steps: + +Parse/generate AST (`v.parser`) => Check types (`v.checker`) +=> Generate C/JavaScript/machine code (`v.gen`) + + +The main files are: + +1. `cmd/v/v.v` The entry point. + +- V figures out the build mode. +- Constructs the compiler object (`struct V`). +- Creates a list of .v files that need to be parsed. +- Creates a parser object for each file and runs `parse()` on them. +- The correct backend is called (C, JS, native), and a binary is compiled. + +2. `v/scanner` The scanner's job is to parse a list of characters and convert +them to tokens. + +3. `v/token` This is simply a list of all tokens, their string values, and a +couple of helper functions. + +4. `v/parser` The parser. It converts a list of tokens into an AST. +In V, objects can be used before declaration, so unknown types are marked as +unresolved. They are resolved later in the type checker. + +5. `v/table` V creates one table object that is shared by all parsers. It +contains all types, consts, and functions, as well as several helpers to search +for objects by name, register new objects, modify types' fields, etc. + +6. `v/checker` Type checker and resolver. It processes the AST and makes sure +the types are correct. Unresolved types are resolved, type information is added +to the AST. + +7. `v/gen/c` C backend. It simply walks the AST and generates C code that can be +compiled with Clang, GCC, Visual Studio, and TCC. + +8. `json.v` defines the json code generation. This file will be removed once V +supports comptime code generation, and it will be possible to do this using the +language's tools. + +9. `v/gen/native` is the directory with all the machine code generation logic. It +defines a set of functions that translate assembly instructions to machine code +and build the binary from scratch byte by byte. It manually builds all headers, +segments, sections, symtable, relocations, etc. Right now it only has basic +support of the native platform (ELF, MACHO format). + +The rest of the directories are vlib modules: `builtin/` (strings, arrays, +maps), `time/`, `os/`, etc. Their documentation is pretty clear. + +## Example Workflow for Contributing +(provided by [@spytheman](https://github.com/spytheman)) + +(If you don't already have a GitHub account, please create one. Your GitHub +username will be referred to later as 'YOUR_GITHUB_USERNAME'. Change it +accordingly in the steps below.) + +1. Fork https://github.com/vlang/v using GitHub's interface to your own account. +Let's say that the forked repository is at +`https://github.com/YOUR_GITHUB_USERNAME/v` . +2. Clone the main v repository https://github.com/vlang/v to a local folder on +your computer, say named nv/ (`git clone https://github.com/vlang/v nv`) +3. `cd nv` +4. `git remote add pullrequest https://github.com/YOUR_GITHUB_USERNAME/v` +NB: the remote named `pullrequest` should point to YOUR own forked repo, not the +main v repository! After this, your local cloned repository is prepared for +making pullrequests, and you can just do normal git operations such as: +`git pull` `git status` and so on. + +5. When finished with a feature/bugfix/change, you can: +`git checkout -b fix_alabala` +6. `git push pullrequest` # (NOTE: the `pullrequest` remote was setup on step 4) +7. On GitHub's web interface, go to: https://github.com/vlang/v/pulls + + Here the UI shows a dialog with a button to make a new pull request based on + the new pushed branch. + (Example dialog: https://url4e.com/gyazo/images/364edc04.png) + +8. After making your pullrequest (aka, PR), you can continue to work on the +branch `fix_alabala` ... just do again `git push pullrequest` when you have more +commits. + +9. If there are merge conflicts, or a branch lags too much behind V's master, +you can do the following: + + 1. `git pull --rebase origin master` # solve conflicts and do + `git rebase --continue` + 2. `git push pullrequest -f` # this will overwrite your current remote branch + with the updated version of your changes. + +The point of doing the above steps, is to never directly push to the main V +repository, *only to your own fork*. Since your local `master` branch tracks the +main V repository's master, then `git checkout master`, as well as +`git pull --rebase origin master` will continue to work as expected +(these are actually used by `v up`) and git can always do it cleanly. + +Git is very flexible, so there are other ways to accomplish the same thing. +See the [GitHub flow](https://guides.github.com/introduction/git-handbook/#github), for more information. + +## Using Github's hub CLI tool + +You can download the `hub` tool from https://hub.github.com/ . Using +`hub`, you will not need to go through the (sometimes) slow website +to make PRs. Most remote operations can be done through the `hub` CLI +command. + +NB: You still need to have a GitHub account. + +### Preparation: +(steps 1..3 need to be done just *once*): + +1. `hub clone vlang/v my_v` +2. `cd my_v` +3. `hub fork --remote-name pullrequest` + +4. `git checkout -b my_cool_feature` # Step 4 is better done *once per each new +feature/bugfix* that you make. + +### Improve V by making commits: + +5. `git commit -am "math: add a new function copysign"` + +### Testing your commits locally: +You can test locally whether your changes have not broken something by +running: `v test-all`. See `TESTS.md` for more details. + +### Publishing your commits to GitHub: + +6. `git push pullrequest` + +### Making a PR with `hub`: +(so that your changes can be merged to the main V repository) + +7. `hub pull-request` + +Optionally, you can track the status of your PR CI tests with: + +8. `hub ci-status --verbose` + +### Fixing failing tests: +If everything is OK, after 5-10 minutes, the CI tests should pass for +all platforms. If not, visit the URLs for the failing CI jobs, see +which tests have failed and then fix them by making more changes. Just use +`git push pullrequest` to publish your changes.

      + +## Key Features of V + +- Simplicity: the language can be learned in less than an hour +- Fast compilation: ≈110k loc/s with a Clang backend, + ≈1 million loc/s with native and tcc backends *(Intel i5-7500, SSD, no optimization)* ([demo video](https://www.youtube.com/watch?v=pvP6wmcl_Sc)) +- Easy to develop: V compiles itself in less than a second +- Performance: as fast as C (V's main backend compiles to human readable C) +- Safety: no null, no globals, no undefined behavior, immutability by default +- C to V translation +- Hot code reloading +- [Innovative memory management](https://vlang.io/#memory) ([demo video](https://www.youtube.com/watch?v=gmB8ea8uLsM)) +- [Cross-platform UI library](https://github.com/vlang/ui) +- Built-in graphics library +- Easy cross compilation +- REPL +- [Built-in ORM](https://github.com/vlang/v/blob/master/doc/docs.md#orm) +- [Built-in web framework](https://github.com/vlang/v/blob/master/vlib/vweb/README.md) +- C and JavaScript backends + +## Stability guarantee and future changes + +Despite being at an early development stage, the V language is relatively stable and has +backwards compatibility guarantee, meaning that the code you write today is guaranteed +to work a month, a year, or five years from now. + +There still may be minor syntax changes before the 1.0 release, but they will be handled +automatically via `vfmt`, as has been done in the past. + +The V core APIs (primarily the `os` module) will still have minor changes until +they are stabilized in V 1.0. Of course the APIs will grow after that, but without breaking +existing code. + +Unlike many other languages, V is not going to be always changing, with new features +being introduced and old features modified. It is always going to be a small and simple +language, very similar to the way it is right now. + +## Installing V from source + +### Linux, macOS, Windows, *BSD, Solaris, WSL, Android, Raspbian + +```bash +git clone https://github.com/vlang/v +cd v +make +``` + +That's it! Now you have a V executable at `[path to V repo]/v`. +`[path to V repo]` can be anywhere. + +(On Windows `make` means running `make.bat`, so make sure you use `cmd.exe`) + +Now you can try `./v run examples/hello_world.v` (`v.exe` on Windows). + +V is constantly being updated. To update V, simply run: + +```bash +v up +``` + +### C compiler + +It's recommended to use Clang, GCC, or Visual Studio. +If you are doing development, you most likely already have one of those installed. + +Otherwise, follow these instructions: + +- [Installing a C compiler on Linux and macOS](https://github.com/vlang/v/wiki/Installing-a-C-compiler-on-Linux-and-macOS) + +- [Installing a C compiler on Windows](https://github.com/vlang/v/wiki/Installing-a-C-compiler-on-Windows) + +However, if none is found when running `make` on Linux or Windows, +TCC is downloaded as the default C backend. +It's very lightweight (several MB) so this shouldn't take too long. + +### Symlinking + +NB: it is *highly recommended*, that you put V on your PATH. That saves +you the effort to type in the full path to your v executable every time. +V provides a convenience `v symlink` command to do that more easily. + +On Unix systems, it creates a `/usr/local/bin/v` symlink to your +executable. To do that, run: + +```bash +sudo ./v symlink +``` + +On Windows, start a new shell with administrative privileges, for +example by Windows Key, then type `cmd.exe`, right click on its menu +entry, and choose `Run as administrator`. In the new administrative +shell, cd to the path, where you have compiled v.exe, then type: + +```bat +.\v.exe symlink +``` + +That will make V available everywhere, by adding it to your PATH. +Please restart your shell/editor after that, so that it can pick +the new PATH variable. + +NB: there is no need to run `v symlink` more than once - v will +continue to be available, even after `v up`, restarts and so on. +You only need to run it again, if you decide to move the V repo +folder somewhere else. + +### Docker + +

      + + + +## Hello World + + +```v +fn main() { + println('hello world') +} +``` + +Save this snippet into a file named `hello.v`. Now do: `v run hello.v`. + +> That is assuming you have symlinked your V with `v symlink`, as described +[here](https://github.com/vlang/v/blob/master/README.md#symlinking). +If you haven't yet, you have to type the path to V manually. + +Congratulations - you just wrote and executed your first V program! + +You can compile a program without execution with `v hello.v`. +See `v help` for all supported commands. + +From the example above, you can see that functions are declared with the `fn` keyword. +The return type is specified after the function name. +In this case `main` doesn't return anything, so there is no return type. + +As in many other languages (such as C, Go, and Rust), `main` is the entry point of your program. + +`println` is one of the few built-in functions. +It prints the value passed to it to standard output. + +`fn main()` declaration can be skipped in one file programs. +This is useful when writing small programs, "scripts", or just learning the language. +For brevity, `fn main()` will be skipped in this tutorial. + +This means that a "hello world" program in V is as simple as + +```v +println('hello world') +``` + +## Running a project folder with several files + +Suppose you have a folder with several .v files in it, where one of them +contains your `main()` function, and the other files have other helper +functions. They may be organized by topic, but still *not yet* structured +enough to be their own separate reusable modules, and you want to compile +them all into one program. + +In other languages, you would have to use includes or a build system +to enumerate all files, compile them separately to object files, +then link them into one final executable. + +In V however, you can compile and run the whole folder of .v files together, +using just `v run .`. Passing parameters also works, so you can +do: `v run . --yourparam some_other_stuff` + +The above will first compile your files into a single program (named +after your folder/project), and then it will execute the program with +`--yourparam some_other_stuff` passed to it as CLI parameters. + +Your program can then use the CLI parameters like this: +```v +import os + +println(os.args) +``` +NB: after a successful run, V will delete the generated executable. +If you want to keep it, use `v -keepc run .` instead, or just compile +manually with `v .` . + +NB: any V compiler flags should be passed *before* the `run` command. +Everything after the source file/folder, will be passed to the program +as is - it will not be processed by V. + +## Comments + +```v +// This is a single line comment. +/* +This is a multiline comment. + /* It can be nested. */ +*/ +``` + +## Functions + +```v +fn main() { + println(add(77, 33)) + println(sub(100, 50)) +} + +fn add(x int, y int) int { + return x + y +} + +fn sub(x int, y int) int { + return x - y +} +``` + +Again, the type comes after the argument's name. + +Just like in Go and C, functions cannot be overloaded. +This simplifies the code and improves maintainability and readability. + +Functions can be used before their declaration: +`add` and `sub` are declared after `main`, but can still be called from `main`. +This is true for all declarations in V and eliminates the need for header files +or thinking about the order of files and declarations. + +### Returning multiple values + +```v +fn foo() (int, int) { + return 2, 3 +} + +a, b := foo() +println(a) // 2 +println(b) // 3 +c, _ := foo() // ignore values using `_` +``` + +## Symbol visibility + +```v +pub fn public_function() { +} + +fn private_function() { +} +``` + +Functions are private (not exported) by default. +To allow other modules to use them, prepend `pub`. The same applies +to constants and types. + +Note: `pub` can only be used from a named module. +For information about creating a module, see [Modules](#modules). + +## Variables + +```v +name := 'Bob' +age := 20 +large_number := i64(9999999999) +println(name) +println(age) +println(large_number) +``` + +Variables are declared and initialized with `:=`. This is the only +way to declare variables in V. This means that variables always have an initial +value. + +The variable's type is inferred from the value on the right hand side. +To choose a different type, use type conversion: +the expression `T(v)` converts the value `v` to the +type `T`. + +Unlike most other languages, V only allows defining variables in functions. +Global (module level) variables are not allowed. There's no global state in V +(see [Pure functions by default](#pure-functions-by-default) for details). + +For consistency across different code bases, all variable and function names +must use the `snake_case` style, as opposed to type names, which must use `PascalCase`. + +### Mutable variables + +```v +mut age := 20 +println(age) +age = 21 +println(age) +``` + +To change the value of the variable use `=`. In V, variables are +immutable by default. +To be able to change the value of the variable, you have to declare it with `mut`. + +Try compiling the program above after removing `mut` from the first line. + +### Initialization vs assignment + +Note the (important) difference between `:=` and `=`. +`:=` is used for declaring and initializing, `=` is used for assigning. + +```v failcompile +fn main() { + age = 21 +} +``` + +This code will not compile, because the variable `age` is not declared. +All variables need to be declared in V. + +```v +fn main() { + age := 21 +} +``` + +The values of multiple variables can be changed in one line. +In this way, their values can be swapped without an intermediary variable. + +```v +mut a := 0 +mut b := 1 +println('$a, $b') // 0, 1 +a, b = b, a +println('$a, $b') // 1, 0 +``` + +### Declaration errors + +In development mode the compiler will warn you that you haven't used the variable +(you'll get an "unused variable" warning). +In production mode (enabled by passing the `-prod` flag to v – `v -prod foo.v`) +it will not compile at all (like in Go). + +```v failcompile nofmt +fn main() { + a := 10 + if true { + a := 20 // error: redefinition of `a` + } + // warning: unused variable `a` +} +``` + +Unlike most languages, variable shadowing is not allowed. Declaring a variable with a name +that is already used in a parent scope will cause a compilation error. + +You can shadow imported modules though, as it is very useful in some situations: +```v ignore +import ui +import gg + +fn draw(ctx &gg.Context) { + gg := ctx.parent.get_ui().gg + gg.draw_rect(10, 10, 100, 50) +} +``` + +## V Types + +### Primitive types + +```v ignore +bool + +string + +i8 i16 int i64 i128 (soon) +byte u16 u32 u64 u128 (soon) + +rune // represents a Unicode code point + +f32 f64 + +voidptr, size_t // these are mostly used for C interoperability + +any // similar to C's void* and Go's interface{} +``` + +Please note that unlike C and Go, `int` is always a 32 bit integer. + +There is an exception to the rule that all operators +in V must have values of the same type on both sides. A small primitive type +on one side can be automatically promoted if it fits +completely into the data range of the type on the other side. +These are the allowed possibilities: + +```v ignore + i8 → i16 → int → i64 + ↘ ↘ + f32 → f64 + ↗ ↗ + byte → u16 → u32 → u64 ⬎ + ↘ ↘ ↘ ptr + i8 → i16 → int → i64 ⬏ +``` +An `int` value for example can be automatically promoted to `f64` +or `i64` but not to `u32`. (`u32` would mean loss of the sign for +negative values). +Promotion from `int` to `f32`, however, is currently done automatically +(but can lead to precision loss for large values). + +Literals like `123` or `4.56` are treated in a special way. They do +not lead to type promotions, however they default to `int` and `f64` +respectively, when their type has to be decided: + +```v nofmt +u := u16(12) +v := 13 + u // v is of type `u16` - no promotion +x := f32(45.6) +y := x + 3.14 // x is of type `f32` - no promotion +a := 75 // a is of type `int` - default for int literal +b := 14.7 // b is of type `f64` - default for float literal +c := u + a // c is of type `int` - automatic promotion of `u`'s value +d := b + x // d is of type `f64` - automatic promotion of `x`'s value +``` + +### Strings + +```v +name := 'Bob' +println(name.len) +println(name[0]) // indexing gives a byte B +println(name[1..3]) // slicing gives a string 'ob' +windows_newline := '\r\n' // escape special characters like in C +assert windows_newline.len == 2 +``` + +In V, a string is a read-only array of bytes. String data is encoded using UTF-8. +String values are immutable. You cannot mutate elements: + +```v failcompile +mut s := 'hello 🌎' +s[0] = `H` // not allowed +``` +> error: cannot assign to `s[i]` since V strings are immutable + +Note that indexing a string will produce a `byte`, not a `rune`. Indexes correspond +to bytes in the string, not Unicode code points. + +Character literals have type `rune`. To denote them, use ` + +```v +rocket := `🚀` +assert 'aloha!'[0] == `a` +``` + +Both single and double quotes can be used to denote strings. For consistency, +`vfmt` converts double quotes to single quotes unless the string contains a single quote character. + +For raw strings, prepend `r`. Raw strings are not escaped: + +```v +s := r'hello\nworld' +println(s) // "hello\nworld" +``` + +Strings can be easily converted to integers: + +```v +s := '42' +n := s.int() // 42 +``` + +### Runes +A `rune` represents a unicode character and is an alias for `u32`. Runes can be created like this: +```v +x := `🚀` +``` + +A string can be converted to runes by the `.runes()` method. +```v +hello := 'Hello World 👋' +hello_runes := hello.runes() // [`H`, `e`, `l`, `l`, `o`, ` `, `W`, `o`, `r`, `l`, `d`, ` `, `👋`] +``` + +### String interpolation + +Basic interpolation syntax is pretty simple - use `$` before a variable name. +The variable will be converted to a string and embedded into the literal: +```v +name := 'Bob' +println('Hello, $name!') // Hello, Bob! +``` +It also works with fields: `'age = $user.age'`. +If you need more complex expressions, use `${}`: `'can register = ${user.age > 13}'`. + +Format specifiers similar to those in C's `printf()` are also supported. +`f`, `g`, `x`, etc. are optional and specify the output format. +The compiler takes care of the storage size, so there is no `hd` or `llu`. + +```v +x := 123.4567 +println('x = ${x:4.2f}') +println('[${x:10}]') // pad with spaces on the left => [ 123.457] +println('[${int(x):-10}]') // pad with spaces on the right => [123 ] +println('[${int(x):010}]') // pad with zeros on the left => [0000000123] +``` + +### String operators + +```v +name := 'Bob' +bobby := name + 'by' // + is used to concatenate strings +println(bobby) // "Bobby" +mut s := 'hello ' +s += 'world' // `+=` is used to append to a string +println(s) // "hello world" +``` + +All operators in V must have values of the same type on both sides. +You cannot concatenate an integer to a string: + +```v failcompile +age := 10 +println('age = ' + age) // not allowed +``` +> error: infix expr: cannot use `int` (right expression) as `string` + +We have to either convert `age` to a `string`: + +```v +age := 11 +println('age = ' + age.str()) +``` + +or use string interpolation (preferred): + +```v +age := 12 +println('age = $age') +``` + +### Numbers + +```v +a := 123 +``` + +This will assign the value of 123 to `a`. By default `a` will have the +type `int`. + +You can also use hexadecimal, binary or octal notation for integer literals: + +```v +a := 0x7B +b := 0b01111011 +c := 0o173 +``` + +All of these will be assigned the same value, 123. They will all have type +`int`, no matter what notation you used. + +V also supports writing numbers with `_` as separator: + +```v +num := 1_000_000 // same as 1000000 +three := 0b0_11 // same as 0b11 +float_num := 3_122.55 // same as 3122.55 +hexa := 0xF_F // same as 255 +oct := 0o17_3 // same as 0o173 +``` + +If you want a different type of integer, you can use casting: + +```v +a := i64(123) +b := byte(42) +c := i16(12345) +``` + +Assigning floating point numbers works the same way: + +```v +f := 1.0 +f1 := f64(3.14) +f2 := f32(3.14) +``` +If you do not specify the type explicitly, by default float literals +will have the type of `f64`. + +Float literals can also be declared as a power of ten: +```v +f0 := 42e1 // 420 +f1 := 123e-2 // 1.23 +f2 := 456e+2 // 45600 +``` + +### Arrays +#### Basic Array Concepts +Arrays are collections of data elements of the same type. They can be represented by +a list of elements surrounded by brackets. The elements can be accessed by appending +an *index* (starting with `0`) in brackets to the array variable: +```v +mut nums := [1, 2, 3] +println(nums) // `[1, 2, 3]` +println(nums[0]) // `1` +println(nums[1]) // `2` +nums[1] = 5 +println(nums) // `[1, 5, 3]` +``` +#### Array Properties +There are two properties that control the "size" of an array: +* `len`: *length* - the number of pre-allocated and initialized elements in the array +* `cap`: *capacity* - the amount of memory space which has been reserved for elements, +but not initialized or counted as elements. The array can grow up to this size without +being reallocated. Usually, V takes care of this property automatically but there are +cases where the user may want to do manual optimizations (see [below](#array-initialization)). + +```v +mut nums := [1, 2, 3] +println(nums.len) // "3" +println(nums.cap) // "3" or greater +nums = [] // The array is now empty +println(nums.len) // "0" +``` + +Note that the properties are read-only fields and can't be modified by the user. + +#### Array Initialization +The basic initialization syntax is as described [above](#basic-array-concepts). +The type of an array is determined by the first element: +* `[1, 2, 3]` is an array of ints (`[]int`). +* `['a', 'b']` is an array of strings (`[]string`). + +The user can explicitly specify the type for the first element: `[byte(16), 32, 64, 128]`. +V arrays are homogeneous (all elements must have the same type). +This means that code like `[1, 'a']` will not compile. + +The above syntax is fine for a small number of known elements but for very large or empty +arrays there is a second initialization syntax: +```v +mut a := []int{len: 10000, cap: 30000, init: 3} +``` +This creates an array of 10000 `int` elements that are all initialized with `3`. Memory +space is reserved for 30000 elements. The parameters `len`, `cap` and `init` are optional; +`len` defaults to `0` and `init` to the default initialization of the element type (`0` +for numerical type, `''` for `string`, etc). The run time system makes sure that the +capacity is not smaller than `len` (even if a smaller value is specified explicitly): + +```v +arr := []int{len: 5, init: -1} +// `arr == [-1, -1, -1, -1, -1]`, arr.cap == 5 + +// Declare an empty array: +users := []int{} +``` + + +Setting the capacity improves performance of pushing elements to the array +as reallocations can be avoided: + +```v +mut numbers := []int{cap: 1000} +println(numbers.len) // 0 +// Now appending elements won't reallocate +for i in 0 .. 1000 { + numbers << i +} +``` +Note: The above code uses a [range `for`](#range-for) statement and a +[push operator (`<<`)](#array-operations). + +#### Array Types + +An array can be of these types: +| Types | Example Definition | +| ------------ | ------------------------------------ | +| Number | `[]int,[]i64` | +| String | `[]string` | +| Rune | `[]rune` | +| Boolean | `[]bool` | +| Array | `[][]int` | +| Struct | `[]MyStructName` | +| Channel | `[]chan f64` | +| Function | `[]MyFunctionType` `[]fn (int) bool` | +| Interface | `[]MyInterfaceName` | +| Sum Type | `[]MySumTypeName` | +| Generic Type | `[]T` | +| Map | `[]map[string]f64` | +| Enum | `[]MyEnumType` | +| Alias | `[]MyAliasTypeName` | +| Thread | `[]thread int` | +| Reference | `[]&f64` | +| Shared | `[]shared MyStructType` | + +**Example Code:** + +This example uses [Structs](#structs) and [Sum Types](#sum-types) to create an array +which can handle different types (e.g. Points, Lines) of data elements. + +```v +struct Point { + x int + y int +} + +struct Line { + p1 Point + p2 Point +} + +type ObjectSumType = Line | Point + +mut object_list := []ObjectSumType{} +object_list << Point{1, 1} +object_list << Line{ + p1: Point{3, 3} + p2: Point{4, 4} +} +dump(object_list) +/* +object_list: [ObjectSumType(Point{ + x: 1 + y: 1 +}), ObjectSumType(Line{ + p1: Point{ + x: 3 + y: 3 + } + p2: Point{ + x: 4 + y: 4 + } +})] +*/ +``` + +#### Multidimensional Arrays + +Arrays can have more than one dimension. + +2d array example: +```v +mut a := [][]int{len: 2, init: []int{len: 3}} +a[0][1] = 2 +println(a) // [[0, 2, 0], [0, 0, 0]] +``` + +3d array example: +```v +mut a := [][][]int{len: 2, init: [][]int{len: 3, init: []int{len: 2}}} +a[0][1][1] = 2 +println(a) // [[[0, 0], [0, 2], [0, 0]], [[0, 0], [0, 0], [0, 0]]] +``` + +#### Array Operations + +Elements can be appended to the end of an array using the push operator `<<`. +It can also append an entire array. + +```v +mut nums := [1, 2, 3] +nums << 4 +println(nums) // "[1, 2, 3, 4]" +// append array +nums << [5, 6, 7] +println(nums) // "[1, 2, 3, 4, 5, 6, 7]" +mut names := ['John'] +names << 'Peter' +names << 'Sam' +// names << 10 <-- This will not compile. `names` is an array of strings. +``` + +`val in array` returns true if the array contains `val`. See [`in` operator](#in-operator). + +```v +names := ['John', 'Peter', 'Sam'] +println(names.len) // "3" +println('Alex' in names) // "false" +``` + + +#### Array methods + +All arrays can be easily printed with `println(arr)` and converted to a string +with `s := arr.str()`. + +Copying the data from the array is done with `.clone()`: + +```v +nums := [1, 2, 3] +nums_copy := nums.clone() +``` + +Arrays can be efficiently filtered and mapped with the `.filter()` and +`.map()` methods: + +```v +nums := [1, 2, 3, 4, 5, 6] +even := nums.filter(it % 2 == 0) +println(even) // [2, 4, 6] +// filter can accept anonymous functions +even_fn := nums.filter(fn (x int) bool { + return x % 2 == 0 +}) +println(even_fn) +words := ['hello', 'world'] +upper := words.map(it.to_upper()) +println(upper) // ['HELLO', 'WORLD'] +// map can also accept anonymous functions +upper_fn := words.map(fn (w string) string { + return w.to_upper() +}) +println(upper_fn) // ['HELLO', 'WORLD'] +``` + +`it` is a builtin variable which refers to element currently being processed in filter/map methods. + +Additionally, `.any()` and `.all()` can be used to conveniently test +for elements that satisfy a condition. + +```v +nums := [1, 2, 3] +println(nums.any(it == 2)) // true +println(nums.all(it >= 2)) // false +``` + +There are further built in methods for arrays: +* `b := a.repeat(n)` concatenate `n` times the elements of `a` +* `a.insert(i, val)` insert new element `val` at index `i` and move all following elements upwards +* `a.insert(i, [3, 4, 5])` insert several elements +* `a.prepend(val)` insert value at beginning, equivalent to `a.insert(0, val)` +* `a.prepend(arr)` insert elements of array `arr` at beginning +* `a.trim(new_len)` truncate the length (if `new_length < a.len`, otherwise do nothing) +* `a.clear()` empty the array (without changing `cap`, equivalent to `a.trim(0)`) +* `a.delete_many(start, size)` removes `size` consecutive elements beginning with index `start` + – triggers reallocation +* `a.delete(index)` equivalent to `a.delete_many(index, 1)` +* `v := a.first()` equivalent to `v := a[0]` +* `v := a.last()` equivalent to `v := a[a.len - 1]` +* `v := a.pop()` get last element and remove it from array +* `a.delete_last()` remove last element from array +* `b := a.reverse()` make `b` contain the elements of `a` in reversed order +* `a.reverse_in_place()` reverse the order of elements in `a` +* `a.join(joiner)` concatenate array of strings into a string using `joiner` string as a separator + +#### Sorting Arrays + +Sorting arrays of all kinds is very simple and intuitive. Special variables `a` and `b` +are used when providing a custom sorting condition. + +```v +mut numbers := [1, 3, 2] +numbers.sort() // 1, 2, 3 +numbers.sort(a > b) // 3, 2, 1 +``` + +```v +struct User { + age int + name string +} + +mut users := [User{21, 'Bob'}, User{20, 'Zarkon'}, User{25, 'Alice'}] +users.sort(a.age < b.age) // sort by User.age int field +users.sort(a.name > b.name) // reverse sort by User.name string field +``` +V also supports custom sorting, through the `sort_with_compare` array method. +Which expects a comparing function which will define the sort order. +Useful for sorting on multiple fields at the same time by custom sorting rules. +The code below sorts the array ascending on `name` and descending `age`. +```v +struct User { + age int + name string +} + +mut users := [User{21, 'Bob'}, User{65, 'Bob'}, User{25, 'Alice'}] + +custom_sort_fn := fn (a &User, b &User) int { + // return -1 when a comes before b + // return 0, when both are in same order + // return 1 when b comes before a + if a.name == b.name { + if a.age < b.age { + return 1 + } + if a.age > b.age { + return -1 + } + return 0 + } + if a.name < b.name { + return -1 + } else if a.name > b.name { + return 1 + } + return 0 +} +users.sort_with_compare(custom_sort_fn) +``` + +#### Array Slices + +A slice is a part of a parent array. Initially it refers to the elements +between two indices separated by a `..` operator. The right-side index must +be greater than or equal to the left side index. + +If a right-side index is absent, it is assumed to be the array length. If a +left-side index is absent, it is assumed to be 0. + +```v +nums := [0, 10, 20, 30, 40] +println(nums[1..4]) // [10, 20, 30] +println(nums[..4]) // [0, 10, 20, 30] +println(nums[1..]) // [10, 20, 30, 40] +``` + +In V slices are arrays themselves (they are no distinct types). As a result +all array operations may be performed on them. E.g. they can be pushed onto an +array of the same type: + +```v +array_1 := [3, 5, 4, 7, 6] +mut array_2 := [0, 1] +array_2 << array_1[..3] +println(array_2) // `[0, 1, 3, 5, 4]` +``` + +A slice is always created with the smallest possible capacity `cap == len` (see +[`cap` above](#array-initialization)) no matter what the capacity or length +of the parent array is. As a result it is immediately reallocated and copied to another +memory location when the size increases thus becoming independent from the +parent array (*copy on grow*). In particular pushing elements to a slice +does not alter the parent: +```v +mut a := [0, 1, 2, 3, 4, 5] +mut b := a[2..4] +b[0] = 7 // `b[0]` is referring to `a[2]` +println(a) // `[0, 1, 7, 3, 4, 5]` +b << 9 +// `b` has been reallocated and is now independent from `a` +println(a) // `[0, 1, 7, 3, 4, 5]` - no change +println(b) // `[7, 3, 9]` +``` + +Appending to the parent array may or may not make it independent from its child slices. +The behaviour depends on the parent's capacity and is predictable: +```v +mut a := []int{len: 5, cap: 6, init: 2} +mut b := a[1..4] +a << 3 +// no reallocation - fits in `cap` +b[2] = 13 // `a[3]` is modified +a << 4 +// a has been reallocated and is now independent from `b` (`cap` was exceeded) +b[1] = 3 // no change in `a` +println(a) // `[2, 2, 2, 13, 2, 3, 4]` +println(b) // `[2, 3, 13]` +``` + +### Fixed size arrays + +V also supports arrays with fixed size. Unlike ordinary arrays, their +length is constant. You cannot append elements to them, nor shrink them. +You can only modify their elements in place. + +However, access to the elements of fixed size arrays is more efficient, +they need less memory than ordinary arrays, and unlike ordinary arrays, +their data is on the stack, so you may want to use them as buffers if you +do not want additional heap allocations. + +Most methods are defined to work on ordinary arrays, not on fixed size arrays. +You can convert a fixed size array to an ordinary array with slicing: +```v +mut fnums := [3]int{} // fnums is a fixed size array with 3 elements. +fnums[0] = 1 +fnums[1] = 10 +fnums[2] = 100 +println(fnums) // => [1, 10, 100] +println(typeof(fnums).name) // => [3]int + +fnums2 := [1, 10, 100]! // short init syntax that does the same (the syntax will probably change) + +anums := fnums[0..fnums.len] +println(anums) // => [1, 10, 100] +println(typeof(anums).name) // => []int +``` +Note that slicing will cause the data of the fixed size array to be copied to +the newly created ordinary array. + +### Maps + +```v +mut m := map[string]int{} // a map with `string` keys and `int` values +m['one'] = 1 +m['two'] = 2 +println(m['one']) // "1" +println(m['bad_key']) // "0" +println('bad_key' in m) // Use `in` to detect whether such key exists +m.delete('two') +``` +Maps can have keys of type string, rune, integer, float or voidptr. + +The whole map can be initialized using this short syntax: +```v +numbers := map{ + 'one': 1 + 'two': 2 +} +println(numbers) +``` + +If a key is not found, a zero value is returned by default: + +```v +sm := map{ + 'abc': 'xyz' +} +val := sm['bad_key'] +println(val) // '' +``` +```v +intm := map{ + 1: 1234 + 2: 5678 +} +s := intm[3] +println(s) // 0 +``` + +It's also possible to use an `or {}` block to handle missing keys: + +```v +mm := map[string]int{} +val := mm['bad_key'] or { panic('key not found') } +``` + +The same optional check applies to arrays: + +```v +arr := [1, 2, 3] +large_index := 999 +val := arr[large_index] or { panic('out of bounds') } +``` + +## Module imports + +For information about creating a module, see [Modules](#modules). + +Modules can be imported using the `import` keyword: + +```v +import os + +fn main() { + // read text from stdin + name := os.input('Enter your name: ') + println('Hello, $name!') +} +``` +This program can use any public definitions from the `os` module, such +as the `input` function. See the [standard library](https://modules.vlang.io/) +documentation for a list of common modules and their public symbols. + +By default, you have to specify the module prefix every time you call an external function. +This may seem verbose at first, but it makes code much more readable +and easier to understand - it's always clear which function from +which module is being called. This is especially useful in large code bases. + +Cyclic module imports are not allowed, like in Go. + +### Selective imports + +You can also import specific functions and types from modules directly: + +```v +import os { input } + +fn main() { + // read text from stdin + name := input('Enter your name: ') + println('Hello, $name!') +} +``` +Note: This will import the module as well. Also, this is not allowed for +constants - they must always be prefixed. + +You can import several specific symbols at once: + +```v +import os { input, user_os } + +name := input('Enter your name: ') +println('Name: $name') +os := user_os() +println('Your OS is ${os}.') +``` + +### Module import aliasing + +Any imported module name can be aliased using the `as` keyword: + +NOTE: this example will not compile unless you have created `mymod/sha256.v` +```v failcompile +import crypto.sha256 +import mymod.sha256 as mysha256 + +fn main() { + v_hash := sha256.sum('hi'.bytes()).hex() + my_hash := mysha256.sum('hi'.bytes()).hex() + assert my_hash == v_hash +} +``` + +You cannot alias an imported function or type. +However, you _can_ redeclare a type. + +```v +import time +import math + +type MyTime = time.Time + +fn (mut t MyTime) century() int { + return int(1.0 + math.trunc(f64(t.year) * 0.009999794661191)) +} + +fn main() { + mut my_time := MyTime{ + year: 2020 + month: 12 + day: 25 + } + println(time.new_time(my_time).utc_string()) + println('Century: $my_time.century()') +} +``` + +## Statements & expressions + +### If + +```v +a := 10 +b := 20 +if a < b { + println('$a < $b') +} else if a > b { + println('$a > $b') +} else { + println('$a == $b') +} +``` + +`if` statements are pretty straightforward and similar to most other languages. +Unlike other C-like languages, +there are no parentheses surrounding the condition and the braces are always required. + +`if` can be used as an expression: + +```v +num := 777 +s := if num % 2 == 0 { 'even' } else { 'odd' } +println(s) +// "odd" +``` + +#### Type checks and casts +You can check the current type of a sum type using `is` and its negated form `!is`. + +You can do it either in an `if`: +```v +struct Abc { + val string +} + +struct Xyz { + foo string +} + +type Alphabet = Abc | Xyz + +x := Alphabet(Abc{'test'}) // sum type +if x is Abc { + // x is automatically casted to Abc and can be used here + println(x) +} +if x !is Abc { + println('Not Abc') +} +``` +or using `match`: +```v oksyntax +match x { + Abc { + // x is automatically casted to Abc and can be used here + println(x) + } + Xyz { + // x is automatically casted to Xyz and can be used here + println(x) + } +} +``` + +This works also with struct fields: +```v +struct MyStruct { + x int +} + +struct MyStruct2 { + y string +} + +type MySumType = MyStruct | MyStruct2 + +struct Abc { + bar MySumType +} + +x := Abc{ + bar: MyStruct{123} // MyStruct will be converted to MySumType type automatically +} +if x.bar is MyStruct { + // x.bar is automatically casted + println(x.bar) +} +match x.bar { + MyStruct { + // x.bar is automatically casted + println(x.bar) + } + else {} +} +``` + +Mutable variables can change, and doing a cast would be unsafe. +However, sometimes it's useful to type cast despite mutability. +In such cases the developer must mark the expression with the `mut` keyword +to tell the compiler that they know what they're doing. + +It works like this: +```v oksyntax +mut x := MySumType(MyStruct{123}) +if mut x is MyStruct { + // x is casted to MyStruct even if it's mutable + // without the mut keyword that wouldn't work + println(x) +} +// same with match +match mut x { + MyStruct { + // x is casted to MyStruct even it's mutable + // without the mut keyword that wouldn't work + println(x) + } +} +``` + +### In operator + +`in` allows to check whether an array or a map contains an element. +To do the opposite, use `!in`. + +```v +nums := [1, 2, 3] +println(1 in nums) // true +println(4 !in nums) // true +m := map{ + 'one': 1 + 'two': 2 +} +println('one' in m) // true +println('three' !in m) // true +``` + +It's also useful for writing boolean expressions that are clearer and more compact: + +```v +enum Token { + plus + minus + div + mult +} + +struct Parser { + token Token +} + +parser := Parser{} +if parser.token == .plus || parser.token == .minus || parser.token == .div || parser.token == .mult { + // ... +} +if parser.token in [.plus, .minus, .div, .mult] { + // ... +} +``` + +V optimizes such expressions, +so both `if` statements above produce the same machine code and no arrays are created. + +### For loop + +V has only one looping keyword: `for`, with several forms. + +#### `for`/`in` + +This is the most common form. You can use it with an array, map or +numeric range. + +##### Array `for` + +```v +numbers := [1, 2, 3, 4, 5] +for num in numbers { + println(num) +} +names := ['Sam', 'Peter'] +for i, name in names { + println('$i) $name') + // Output: 0) Sam + // 1) Peter +} +``` + +The `for value in arr` form is used for going through elements of an array. +If an index is required, an alternative form `for index, value in arr` can be used. + +Note, that the value is read-only. +If you need to modify the array while looping, you need to declare the element as mutable: + +```v +mut numbers := [0, 1, 2] +for mut num in numbers { + num++ +} +println(numbers) // [1, 2, 3] +``` +When an identifier is just a single underscore, it is ignored. + +##### Custom iterators +Types that implement a `next` method returning an `Option` can be iterated +with a `for` loop. + +```v +struct SquareIterator { + arr []int +mut: + idx int +} + +fn (mut iter SquareIterator) next() ?int { + if iter.idx >= iter.arr.len { + return error('') + } + defer { + iter.idx++ + } + return iter.arr[iter.idx] * iter.arr[iter.idx] +} + +nums := [1, 2, 3, 4, 5] +iter := SquareIterator{ + arr: nums +} +for squared in iter { + println(squared) +} +``` + +The code above prints: +``` +1 +4 +9 +16 +25 +``` + +##### Map `for` + +```v +m := map{ + 'one': 1 + 'two': 2 +} +for key, value in m { + println('$key -> $value') + // Output: one -> 1 + // two -> 2 +} +``` + +Either key or value can be ignored by using a single underscore as the identifier. +```v +m := map{ + 'one': 1 + 'two': 2 +} +// iterate over keys +for key, _ in m { + println(key) + // Output: one + // two +} +// iterate over values +for _, value in m { + println(value) + // Output: 1 + // 2 +} +``` + +##### Range `for` + +```v +// Prints '01234' +for i in 0 .. 5 { + print(i) +} +``` +`low..high` means an *exclusive* range, which represents all values +from `low` up to *but not including* `high`. + +#### Condition `for` + +```v +mut sum := 0 +mut i := 0 +for i <= 100 { + sum += i + i++ +} +println(sum) // "5050" +``` + +This form of the loop is similar to `while` loops in other languages. +The loop will stop iterating once the boolean condition evaluates to false. +Again, there are no parentheses surrounding the condition, and the braces are always required. + +#### Bare `for` + +```v +mut num := 0 +for { + num += 2 + if num >= 10 { + break + } +} +println(num) // "10" +``` + +The condition can be omitted, resulting in an infinite loop. + +#### C `for` + +```v +for i := 0; i < 10; i += 2 { + // Don't print 6 + if i == 6 { + continue + } + println(i) +} +``` + +Finally, there's the traditional C style `for` loop. It's safer than the `while` form +because with the latter it's easy to forget to update the counter and get +stuck in an infinite loop. + +Here `i` doesn't need to be declared with `mut` since it's always going to be mutable by definition. + +#### Labelled break & continue + +`break` and `continue` control the innermost `for` loop by default. +You can also use `break` and `continue` followed by a label name to refer to an outer `for` +loop: + +```v +outer: for i := 4; true; i++ { + println(i) + for { + if i < 7 { + continue outer + } else { + break outer + } + } +} +``` +The label must immediately precede the outer loop. +The above code prints: +``` +4 +5 +6 +7 +``` + +### Match + +```v +os := 'windows' +print('V is running on ') +match os { + 'darwin' { println('macOS.') } + 'linux' { println('Linux.') } + else { println(os) } +} +``` + +A match statement is a shorter way to write a sequence of `if - else` statements. +When a matching branch is found, the following statement block will be run. +The else branch will be run when no other branches match. + +```v +number := 2 +s := match number { + 1 { 'one' } + 2 { 'two' } + else { 'many' } +} +``` + +A match expression returns the value of the final expression from the matching branch. + +```v +enum Color { + red + blue + green +} + +fn is_red_or_blue(c Color) bool { + return match c { + .red, .blue { true } // comma can be used to test multiple values + .green { false } + } +} +``` + +A match statement can also be used to branch on the variants of an `enum` +by using the shorthand `.variant_here` syntax. An `else` branch is not allowed +when all the branches are exhaustive. + +```v +c := `v` +typ := match c { + `0`...`9` { 'digit' } + `A`...`Z` { 'uppercase' } + `a`...`z` { 'lowercase' } + else { 'other' } +} +println(typ) +// 'lowercase' +``` + +You can also use ranges as `match` patterns. If the value falls within the range +of a branch, that branch will be executed. + +Note that the ranges use `...` (three dots) rather than `..` (two dots). This is +because the range is *inclusive* of the last element, rather than exclusive +(as `..` ranges are). Using `..` in a match branch will throw an error. + +Note: `match` as an expression is not usable in `for` loop and `if` statements. + +### Defer + +A defer statement defers the execution of a block of statements +until the surrounding function returns. + +```v +import os + +fn read_log() { + mut ok := false + mut f := os.open('log.txt') or { panic(err.msg) } + defer { + f.close() + } + // ... + if !ok { + // defer statement will be called here, the file will be closed + return + } + // ... + // defer statement will be called here, the file will be closed +} +``` + +If the function returns a value the `defer` block is executed *after* the return +expression is evaluated: + +```v +import os + +enum State { + normal + write_log + return_error +} + +// write log file and return number of bytes written +fn write_log(s State) ?int { + mut f := os.create('log.txt') ? + defer { + f.close() + } + if s == .write_log { + // `f.close()` will be called after `f.write()` has been + // executed, but before `write_log()` finally returns the + // number of bytes written to `main()` + return f.writeln('This is a log file') + } else if s == .return_error { + // the file will be closed after the `error()` function + // has returned - so the error message will still report + // it as open + return error('nothing written; file open: $f.is_opened') + } + // the file will be closed here, too + return 0 +} + +fn main() { + n := write_log(.return_error) or { + println('Error: $err') + 0 + } + println('$n bytes written') +} +``` + +## Structs + +```v +struct Point { + x int + y int +} + +mut p := Point{ + x: 10 + y: 20 +} +println(p.x) // Struct fields are accessed using a dot +// Alternative literal syntax for structs with 3 fields or fewer +p = Point{10, 20} +assert p.x == 10 +``` + +### Heap structs + +Structs are allocated on the stack. To allocate a struct on the heap +and get a reference to it, use the `&` prefix: + +```v +struct Point { + x int + y int +} + +p := &Point{10, 10} +// References have the same syntax for accessing fields +println(p.x) +``` + +The type of `p` is `&Point`. It's a [reference](#references) to `Point`. +References are similar to Go pointers and C++ references. + +### Embedded structs + +V doesn't allow subclassing, but it supports embedded structs: + +```v +struct Widget { +mut: + x int + y int +} + +struct Button { + Widget + title string +} + +mut button := Button{ + title: 'Click me' +} +button.x = 3 +``` +Without embedding we'd have to name the `Widget` field and do: + +```v oksyntax +button.widget.x = 3 +``` + +### Default field values + +```v +struct Foo { + n int // n is 0 by default + s string // s is '' by default + a []int // a is `[]int{}` by default + pos int = -1 // custom default value +} +``` + +All struct fields are zeroed by default during the creation of the struct. +Array and map fields are allocated. + +It's also possible to define custom default values. + +### Required fields + +```v +struct Foo { + n int [required] +} +``` + +You can mark a struct field with the `[required]` attribute, to tell V that +that field must be initialized when creating an instance of that struct. + +This example will not compile, since the field `n` isn't explicitly initialized: +```v failcompile +_ = Foo{} +``` + + + +### Short struct literal syntax + +```v +struct Point { + x int + y int +} + +mut p := Point{ + x: 10 + y: 20 +} +// you can omit the struct name when it's already known +p = { + x: 30 + y: 4 +} +assert p.y == 4 +// +// array: first element defines type of array +points := [Point{10, 20}, Point{20, 30}, Point{40, 50}] +println(points) // [Point{x: 10, y: 20}, Point{x: 20, y: 30}, Point{x: 40,y: 50}] +``` + +Omitting the struct name also works for returning a struct literal or passing one +as a function argument. + +#### Trailing struct literal arguments + +V doesn't have default function arguments or named arguments, for that trailing struct +literal syntax can be used instead: + +```v +struct ButtonConfig { + text string + is_disabled bool + width int = 70 + height int = 20 +} + +struct Button { + text string + width int + height int +} + +fn new_button(c ButtonConfig) &Button { + return &Button{ + width: c.width + height: c.height + text: c.text + } +} + +button := new_button(text: 'Click me', width: 100) +// the height is unset, so it's the default value +assert button.height == 20 +``` + +As you can see, both the struct name and braces can be omitted, instead of: + +```v oksyntax nofmt +new_button(ButtonConfig{text:'Click me', width:100}) +``` + +This only works for functions that take a struct for the last argument. + +### Access modifiers + +Struct fields are private and immutable by default (making structs immutable as well). +Their access modifiers can be changed with +`pub` and `mut`. In total, there are 5 possible options: + +```v +struct Foo { + a int // private immutable (default) +mut: + b int // private mutable + c int // (you can list multiple fields with the same access modifier) +pub: + d int // public immutable (readonly) +pub mut: + e int // public, but mutable only in parent module +__global: + // (not recommended to use, that's why the 'global' keyword starts with __) + f int // public and mutable both inside and outside parent module +} +``` + +For example, here's the `string` type defined in the `builtin` module: + +```v ignore +struct string { + str &byte +pub: + len int +} +``` + +It's easy to see from this definition that `string` is an immutable type. +The byte pointer with the string data is not accessible outside `builtin` at all. +The `len` field is public, but immutable: +```v failcompile +fn main() { + str := 'hello' + len := str.len // OK + str.len++ // Compilation error +} +``` + +This means that defining public readonly fields is very easy in V, +no need in getters/setters or properties. + +## Methods + +```v +struct User { + age int +} + +fn (u User) can_register() bool { + return u.age > 16 +} + +user := User{ + age: 10 +} +println(user.can_register()) // "false" +user2 := User{ + age: 20 +} +println(user2.can_register()) // "true" +``` + +V doesn't have classes, but you can define methods on types. +A method is a function with a special receiver argument. +The receiver appears in its own argument list between the `fn` keyword and the method name. +Methods must be in the same module as the receiver type. + +In this example, the `can_register` method has a receiver of type `User` named `u`. +The convention is not to use receiver names like `self` or `this`, +but a short, preferably one letter long, name. + +## Unions + +Just like structs, unions support embedding. + +```v +struct Rgba32_Component { + r byte + g byte + b byte + a byte +} + +union Rgba32 { + Rgba32_Component + value u32 +} + +clr1 := Rgba32{ + value: 0x008811FF +} + +clr2 := Rgba32{ + Rgba32_Component: { + a: 128 + } +} + +sz := sizeof(Rgba32) +unsafe { + println('Size: ${sz}B,clr1.b: $clr1.b,clr2.b: $clr2.b') +} +``` + +Output: `Size: 4B, clr1.b: 136, clr2.b: 0` + +Union member access must be performed in an `unsafe` block. + +Note that the embedded struct arguments are not necessarily stored in the order listed. + +## Functions 2 + +### Pure functions by default + +V functions are pure by default, meaning that their return values are a function of their +arguments only, and their evaluation has no side effects (besides I/O). + +This is achieved by a lack of global variables and all function arguments being +immutable by default, even when [references](#references) are passed. + +V is not a purely functional language however. + +There is a compiler flag to enable global variables (`-enable-globals`), but this is +intended for low-level applications like kernels and drivers. + +### Mutable arguments + +It is possible to modify function arguments by using the keyword `mut`: + +```v +struct User { + name string +mut: + is_registered bool +} + +fn (mut u User) register() { + u.is_registered = true +} + +mut user := User{} +println(user.is_registered) // "false" +user.register() +println(user.is_registered) // "true" +``` + +In this example, the receiver (which is simply the first argument) is marked as mutable, +so `register()` can change the user object. The same works with non-receiver arguments: + +```v +fn multiply_by_2(mut arr []int) { + for i in 0 .. arr.len { + arr[i] *= 2 + } +} + +mut nums := [1, 2, 3] +multiply_by_2(mut nums) +println(nums) +// "[2, 4, 6]" +``` + +Note, that you have to add `mut` before `nums` when calling this function. This makes +it clear that the function being called will modify the value. + +It is preferable to return values instead of modifying arguments. +Modifying arguments should only be done in performance-critical parts of your application +to reduce allocations and copying. + +For this reason V doesn't allow the modification of arguments with primitive types (e.g. integers). +Only more complex types such as arrays and maps may be modified. + +Use `user.register()` or `user = register(user)` +instead of `register(mut user)`. + +#### Struct update syntax + +V makes it easy to return a modified version of an object: + +```v +struct User { + name string + age int + is_registered bool +} + +fn register(u User) User { + return { + ...u + is_registered: true + } +} + +mut user := User{ + name: 'abc' + age: 23 +} +user = register(user) +println(user) +``` + +### Variable number of arguments + +```v +fn sum(a ...int) int { + mut total := 0 + for x in a { + total += x + } + return total +} + +println(sum()) // 0 +println(sum(1)) // 1 +println(sum(2, 3)) // 5 +// using array decomposition +a := [2, 3, 4] +println(sum(...a)) // <-- using prefix ... here. output: 9 +b := [5, 6, 7] +println(sum(...b)) // output: 18 +``` + +### Anonymous & higher order functions + +```v +fn sqr(n int) int { + return n * n +} + +fn cube(n int) int { + return n * n * n +} + +fn run(value int, op fn (int) int) int { + return op(value) +} + +fn main() { + // Functions can be passed to other functions + println(run(5, sqr)) // "25" + // Anonymous functions can be declared inside other functions: + double_fn := fn (n int) int { + return n + n + } + println(run(5, double_fn)) // "10" + // Functions can be passed around without assigning them to variables: + res := run(5, fn (n int) int { + return n + n + }) + println(res) // "10" + // You can even have an array/map of functions: + fns := [sqr, cube] + println(fns[0](10)) // "100" + fns_map := map{ + 'sqr': sqr + 'cube': cube + } + println(fns_map['cube'](2)) // "8" +} +``` + +## References + +```v +struct Foo {} + +fn (foo Foo) bar_method() { + // ... +} + +fn bar_function(foo Foo) { + // ... +} +``` + +If a function argument is immutable (like `foo` in the examples above) +V can pass it either by value or by reference. The compiler will decide, +and the developer doesn't need to think about it. + +You no longer need to remember whether you should pass the struct by value +or by reference. + +You can ensure that the struct is always passed by reference by +adding `&`: + +```v +struct Foo { + abc int +} + +fn (foo &Foo) bar() { + println(foo.abc) +} +``` + +`foo` is still immutable and can't be changed. For that, +`(mut foo Foo)` must be used. + +In general, V's references are similar to Go pointers and C++ references. +For example, a generic tree structure definition would look like this: + +```v +struct Node { + val T + left &Node + right &Node +} +``` + +## Constants + +```v +const ( + pi = 3.14 + world = '世界' +) + +println(pi) +println(world) +``` + +Constants are declared with `const`. They can only be defined +at the module level (outside of functions). +Constant values can never be changed. You can also declare a single +constant separately: + +```v +const e = 2.71828 +``` + +V constants are more flexible than in most languages. You can assign more complex values: + +```v +struct Color { + r int + g int + b int +} + +fn rgb(r int, g int, b int) Color { + return Color{ + r: r + g: g + b: b + } +} + +const ( + numbers = [1, 2, 3] + red = Color{ + r: 255 + g: 0 + b: 0 + } + // evaluate function call at compile-time* + blue = rgb(0, 0, 255) +) + +println(numbers) +println(red) +println(blue) +``` +\* WIP - for now function calls are evaluated at program start-up + +Global variables are not normally allowed, so this can be really useful. + +**Modules** + +Constants can be made public with `pub const`: +```v oksyntax +module mymodule + +pub const golden_ratio = 1.61803 + +fn calc() { + println(mymodule.golden_ratio) +} +``` +The `pub` keyword is only allowed before the `const` keyword and cannot be used inside +a `const ( )` block. + +Outside from module main all constants need to be prefixed with the module name. + +### Required module prefix + +When naming constants, `snake_case` must be used. In order to distinguish consts +from local variables, the full path to consts must be specified. For example, +to access the PI const, full `math.pi` name must be used both outside the `math` +module, and inside it. That restriction is relaxed only for the `main` module +(the one containing your `fn main()`), where you can use the unqualified name of +constants defined there, i.e. `numbers`, rather than `main.numbers`. + +vfmt takes care of this rule, so you can type `println(pi)` inside the `math` module, +and vfmt will automatically update it to `println(math.pi)`. + + + +## Builtin functions + +Some functions are builtin like `println`. Here is the complete list: + +```v ignore +fn print(s string) // print anything on sdtout +fn println(s string) // print anything and a newline on sdtout + +fn eprint(s string) // same as print(), but use stderr +fn eprintln(s string) // same as println(), but use stderr + +fn exit(code int) // terminate the program with a custom error code +fn panic(s string) // print a message and backtraces on stderr, and terminate the program with error code 1 +fn print_backtrace() // print backtraces on stderr +``` + +`println` is a simple yet powerful builtin function, that can print anything: +strings, numbers, arrays, maps, structs. + +```v +struct User { + name string + age int +} + +println(1) // "1" +println('hi') // "hi" +println([1, 2, 3]) // "[1, 2, 3]" +println(User{ name: 'Bob', age: 20 }) // "User{name:'Bob', age:20}" +``` + + + +## Printing custom types + +If you want to define a custom print value for your type, simply define a +`.str() string` method: + +```v +struct Color { + r int + g int + b int +} + +pub fn (c Color) str() string { + return '{$c.r, $c.g, $c.b}' +} + +red := Color{ + r: 255 + g: 0 + b: 0 +} +println(red) +``` + +## Modules + +Every file in the root of a folder is part of the same module. +Simple programs don't need to specify module name, in which case it defaults to 'main'. + +V is a very modular language. Creating reusable modules is encouraged and is +quite easy to do. +To create a new module, create a directory with your module's name containing +.v files with code: + +```shell +cd ~/code/modules +mkdir mymodule +vim mymodule/myfile.v +``` +```v failcompile +// myfile.v +module mymodule + +// To export a function we have to use `pub` +pub fn say_hi() { + println('hello from mymodule!') +} +``` + +You can now use `mymodule` in your code: + +```v failcompile +import mymodule + +fn main() { + mymodule.say_hi() +} +``` + +* Module names should be short, under 10 characters. +* Module names must use `snake_case`. +* Circular imports are not allowed. +* You can have as many .v files in a module as you want. +* You can create modules anywhere. +* All modules are compiled statically into a single executable. + +### `init` functions + +If you want a module to automatically call some setup/initialization code when it is imported, +you can use a module `init` function: + +```v +fn init() { + // your setup code here ... +} +``` + +The `init` function cannot be public - it will be called automatically. This feature is +particularly useful for initializing a C library. + +### Manage Packages + +Briefly: + +```powershell +v [module option] [param] +``` + +###### module options: + +``` + install Install a module from VPM. + remove Remove a module that was installed from VPM. + search Search for a module from VPM. + update Update an installed module from VPM. + upgrade Upgrade all the outdated modules. + list List all installed modules. + outdated Show installed modules that need updates. +``` + +Read more: + +You can also install modules already created by someone else with [VPM](https://vpm.vlang.io/): +```powershell +v install [module] +``` +**Example:** +```powershell +v install ui +``` + +Removing a module with v: + +```powershell +v remove [module] +``` +**Example:** +```powershell +v remove ui +``` + +Updating an installed module from [VPM](https://vpm.vlang.io/): + +```powershell +v update [module] +``` +**Example:** +```powershell +v update ui +``` + +Or you can update all your modules: +```powershell +v update +``` + +To see all the modules you have installed, you can use: + +```powershell +v list +``` +**Example:** +```powershell +> v list +Installed modules: + markdown + ui +``` + +To see all the modules you have installed, you can use: +outdated Show installed modules that need updates. +```powershell +v outdated +``` +**Example:** +```powershell +> v outdated +Modules are up to date. +``` + +### Publish package + +1.

No need to use `color = Color.green` here. +color = .green +println(color) // "green" +match color { + .red { println('the color was red') } + .green { println('the color was green') } + .blue { println('the color was blue') } +} +``` + +Enum match must be exhaustive or have an `else` branch. +This ensures that if a new enum field is added, it's handled everywhere in the code. + +Enum fields cannot re-use reserved keywords. However, reserved keywords may be escaped +with an @. + +```v +enum Color { + @none + red + green + blue +} + +color := Color.@none +println(color) +``` + +Integers may be assigned to enum fields. + +```v +enum Grocery { + apple + orange = 5 + pear +} + +g1 := int(Grocery.apple) +g2 := int(Grocery.orange) +g3 := int(Grocery.pear) +println('Grocery IDs: $g1, $g2, $g3') +``` + +Output: `Grocery IDs: 0, 5, 6`. + +Operations are not allowed on enum variables; they must be explicity cast to `int`. + +### Sum types + +A sum type instance can hold a value of several different types. Use the `type` +keyword to declare a sum type: + +```v +struct Moon {} + +struct Mars {} + +struct Venus {} + +type World = Mars | Moon | Venus + +sum := World(Moon{}) +assert sum.type_name() == 'Moon' +println(sum) +``` +The built-in method `type_name` returns the name of the currently held +type. + +With sum types you could build recursive structures and write concise but powerful code on them. +```v +// V's binary tree +struct Empty {} + +struct Node { + value f64 + left Tree + right Tree +} + +type Tree = Empty | Node + +// sum up all node values +fn sum(tree Tree) f64 { + return match tree { + Empty { 0 } + Node { tree.value + sum(tree.left) + sum(tree.right) } + } +} + +fn main() { + left := Node{0.2, Empty{}, Empty{}} + right := Node{0.3, Empty{}, Node{0.4, Empty{}, Empty{}}} + tree := Node{0.5, left, right} + println(sum(tree)) // 0.2 + 0.3 + 0.4 + 0.5 = 1.4 +} +``` + +Enums can have methods, just like structs + +```v +enum Cycle { + one + two + three +} + +fn (c Cycle) next() Cycle { + match c { + .one { + return .two + } + .two { + return .three + } + .three { + return .one + } + } +} + +mut c := Cycle.one +for _ in 0 .. 10 { + println(c) + c = c.next() +} +``` + +Output: +``` +one +two +three +one +two +three +one +two +three +one +``` + +#### Dynamic casts + +To check whether a sum type instance holds a certain type, use `sum is Type`. +To cast a sum type to one of its variants you can use `sum as Type`: + +```v +struct Moon {} + +struct Mars {} + +struct Venus {} + +type World = Mars | Moon | Venus + +fn (m Mars) dust_storm() bool { + return true +} + +fn main() { + mut w := World(Moon{}) + assert w is Moon + w = Mars{} + // use `as` to access the Mars instance + mars := w as Mars + if mars.dust_storm() { + println('bad weather!') + } +} +``` + +`as` will panic if `w` doesn't hold a `Mars` instance. +A safer way is to use a smart cast. + +#### Smart casting + +```v oksyntax +if w is Mars { + assert typeof(w).name == 'Mars' + if w.dust_storm() { + println('bad weather!') + } +} +``` +`w` has type `Mars` inside the body of the `if` statement. This is +known as *flow-sensitive typing*. +If `w` is a mutable identifier, it would be unsafe if the compiler smart casts it without a warning. +That's why you have to declare a `mut` before the `is` expression: + +```v ignore +if mut w is Mars { + assert typeof(w).name == 'Mars' + if w.dust_storm() { + println('bad weather!') + } +} +``` +Otherwise `w` would keep its original type. +> This works for both, simple variables and complex expressions like `user.name` + +#### Matching sum types + +You can also use `match` to determine the variant: + +```v +struct Moon {} + +struct Mars {} + +struct Venus {} + +type World = Mars | Moon | Venus + +fn open_parachutes(n int) { + println(n) +} + +fn land(w World) { + match w { + Moon {} // no atmosphere + Mars { + // light atmosphere + open_parachutes(3) + } + Venus { + // heavy atmosphere + open_parachutes(1) + } + } +} +``` + +`match` must have a pattern for each variant or have an `else` branch. + +```v ignore +struct Moon {} +struct Mars {} +struct Venus {} + +type World = Moon | Mars | Venus + +fn (m Moon) moon_walk() {} +fn (m Mars) shiver() {} +fn (v Venus) sweat() {} + +fn pass_time(w World) { + match w { + // using the shadowed match variable, in this case `w` (smart cast) + Moon { w.moon_walk() } + Mars { w.shiver() } + else {} + } +} +``` + +### Type aliases + +To define a new type `NewType` as an alias for `ExistingType`, +do `type NewType = ExistingType`.
      +This is a special case of a [sum type](#sum-types) declaration. + +### Option/Result types and error handling + +Option types are declared with `?Type`: +```v +struct User { + id int + name string +} + +struct Repo { + users []User +} + +fn (r Repo) find_user_by_id(id int) ?User { + for user in r.users { + if user.id == id { + // V automatically wraps this into an option type + return user + } + } + return error('User $id not found') +} + +fn main() { + repo := Repo{ + users: [User{1, 'Andrew'}, User{2, 'Bob'}, User{10, 'Charles'}] + } + user := repo.find_user_by_id(10) or { // Option types must be handled by `or` blocks + return + } + println(user.id) // "10" + println(user.name) // "Charles" +} +``` + +V combines `Option` and `Result` into one type, so you don't need to decide which one to use. + +The amount of work required to "upgrade" a function to an optional function is minimal; +you have to add a `?` to the return type and return an error when something goes wrong. + +If you don't need to return an error message, you can simply `return none` +(this is a more efficient equivalent of `return error("")`). + +This is the primary mechanism for error handling in V. They are still values, like in Go, +but the advantage is that errors can't be unhandled, and handling them is a lot less verbose. +Unlike other languages, V does not handle exceptions with `throw/try/catch` blocks. + +`err` is defined inside an `or` block and is set to the string message passed +to the `error()` function. `err` is empty if `none` was returned. + +```v oksyntax +user := repo.find_user_by_id(7) or { + println(err) // "User 7 not found" + return +} +``` + +### Handling optionals + +There are four ways of handling an optional. The first method is to +propagate the error: + +```v +import net.http + +fn f(url string) ?string { + resp := http.get(url) ? + return resp.text +} +``` + +`http.get` returns `?http.Response`. Because `?` follows the call, the +error will be propagated to the caller of `f`. When using `?` after a +function call producing an optional, the enclosing function must return +an optional as well. If error propagation is used in the `main()` +function it will `panic` instead, since the error cannot be propagated +any further. + +The body of `f` is essentially a condensed version of: + +```v ignore + resp := http.get(url) or { return err } + return resp.text +``` + +--- +The second method is to break from execution early: + +```v oksyntax +user := repo.find_user_by_id(7) or { return } +``` + +Here, you can either call `panic()` or `exit()`, which will stop the execution of the +entire program, or use a control flow statement (`return`, `break`, `continue`, etc) +to break from the current block. +Note that `break` and `continue` can only be used inside a `for` loop. + +V does not have a way to forcibly "unwrap" an optional (as other languages do, +for instance Rust's `unwrap()` or Swift's `!`). To do this, use `or { panic(err.msg) }` instead. + +--- +The third method is to provide a default value at the end of the `or` block. +In case of an error, that value would be assigned instead, +so it must have the same type as the content of the `Option` being handled. + +```v +fn do_something(s string) ?string { + if s == 'foo' { + return 'foo' + } + return error('invalid string') // Could be `return none` as well +} + +a := do_something('foo') or { 'default' } // a will be 'foo' +b := do_something('bar') or { 'default' } // b will be 'default' +println(a) +println(b) +``` + +--- +The fourth method is to use `if` unwrapping: + +```v +import net.http + +if resp := http.get('https://google.com') { + println(resp.text) // resp is a http.Response, not an optional +} else { + println(err) +} +``` +Above, `http.get` returns a `?http.Response`. `resp` is only in scope for the first +`if` branch. `err` is only in scope for the `else` branch. + +## Generics + +```v wip + +struct Repo { + db DB +} + +struct User { + id int + name string +} + +struct Post { + id int + user_id int + title string + body string +} + +fn new_repo(db DB) Repo { + return Repo{db: db} +} + +// This is a generic function. V will generate it for every type it's used with. +fn (r Repo) find_by_id(id int) ?T { + table_name := T.name // in this example getting the name of the type gives us the table name + return r.db.query_one('select * from $table_name where id = ?', id) +} + +db := new_db() +users_repo := new_repo(db) // returns Repo +posts_repo := new_repo(db) // returns Repo +user := users_repo.find_by_id(1)? // find_by_id +post := posts_repo.find_by_id(1)? // find_by_id +``` + +Currently generic function definitions must declare their type parameters, but in +future V will infer generic type parameters from single-letter type names in +runtime parameter types. This is why `find_by_id` can omit ``, because the +receiver argument `r` uses a generic type `T`. + +Another example: +```v +fn compare(a T, b T) int { + if a < b { + return -1 + } + if a > b { + return 1 + } + return 0 +} + +// compare +println(compare(1, 0)) // Outputs: 1 +println(compare(1, 1)) // 0 +println(compare(1, 2)) // -1 +// compare +println(compare('1', '0')) // Outputs: 1 +println(compare('1', '1')) // 0 +println(compare('1', '2')) // -1 +// compare +println(compare(1.1, 1.0)) // Outputs: 1 +println(compare(1.1, 1.1)) // 0 +println(compare(1.1, 1.2)) // -1 +``` + + +## Concurrency +### Spawning Concurrent Tasks +V's model of concurrency is very similar to Go's. To run `foo()` concurrently in +a different thread, just call it with `go foo()`: + +```v +import math + +fn p(a f64, b f64) { // ordinary function without return value + c := math.sqrt(a * a + b * b) + println(c) +} + +fn main() { + go p(3, 4) + // p will be run in parallel thread +} +``` + +Sometimes it is necessary to wait until a parallel thread has finished. This can +be done by assigning a *handle* to the started thread and calling the `wait()` method +to this handle later: + +```v +import math + +fn p(a f64, b f64) { // ordinary function without return value + c := math.sqrt(a * a + b * b) + println(c) // prints `5` +} + +fn main() { + h := go p(3, 4) + // p() runs in parallel thread + h.wait() + // p() has definitely finished +} +``` + +This approach can also be used to get a return value from a function that is run in a +parallel thread. There is no need to modify the function itself to be able to call it +concurrently. + +```v +import math { sqrt } + +fn get_hypot(a f64, b f64) f64 { // ordinary function returning a value + c := sqrt(a * a + b * b) + return c +} + +fn main() { + g := go get_hypot(54.06, 2.08) // spawn thread and get handle to it + h1 := get_hypot(2.32, 16.74) // do some other calculation here + h2 := g.wait() // get result from spawned thread + println('Results: $h1, $h2') // prints `Results: 16.9, 54.1` +} +``` + +If there is a large number of tasks, it might be easier to manage them +using an array of threads. + +```v +import time + +fn task(id int, duration int) { + println('task $id begin') + time.sleep(duration * time.millisecond) + println('task $id end') +} + +fn main() { + mut threads := []thread{} + threads << go task(1, 500) + threads << go task(2, 900) + threads << go task(3, 100) + threads.wait() + println('done') +} + +// Output: +// task 1 begin +// task 2 begin +// task 3 begin +// task 3 end +// task 1 end +// task 2 end +// done +``` + +Additionally for threads that return the same type, calling `wait()` +on the thread array will return all computed values. + +```v +fn expensive_computing(i int) int { + return i * i +} + +fn main() { + mut threads := []thread int{} + for i in 1 .. 10 { + threads << go expensive_computing(i) + } + // Join all tasks + r := threads.wait() + println('All jobs finished: $r') +} + +// Output: All jobs finished: [1, 4, 9, 16, 25, 36, 49, 64, 81] +``` + +### Channels +Channels are the preferred way to communicate between coroutines. V's channels work basically like +those in Go. You can push objects into a channel on one end and pop objects from the other end. +Channels can be buffered or unbuffered and it is possible to `select` from multiple channels. + +#### Syntax and Usage +Channels have the type `chan objtype`. An optional buffer length can specified as the `cap` property +in the declaration: + +```v +ch := chan int{} // unbuffered - "synchronous" +ch2 := chan f64{cap: 100} // buffer length 100 +``` + +Channels do not have to be declared as `mut`. The buffer length is not part of the type but +a property of the individual channel object. Channels can be passed to coroutines like normal +variables: + +```v +fn f(ch chan int) { + // ... +} + +fn main() { + ch := chan int{} + go f(ch) + // ... +} +``` + +Objects can be pushed to channels using the arrow operator. The same operator can be used to +pop objects from the other end: + +```v +// make buffered channels so pushing does not block (if there is room in the buffer) +ch := chan int{cap: 1} +ch2 := chan f64{cap: 1} +n := 5 +// push +ch <- n +ch2 <- 7.3 +mut y := f64(0.0) +m := <-ch // pop creating new variable +y = <-ch2 // pop into existing variable +``` + +A channel can be closed to indicate that no further objects can be pushed. Any attempt +to do so will then result in a runtime panic (with the exception of `select` and +`try_push()` - see below). Attempts to pop will return immediately if the +associated channel has been closed and the buffer is empty. This situation can be +handled using an or branch (see [Handling Optionals](#handling-optionals)). + +```v wip +ch := chan int{} +ch2 := chan f64{} +// ... +ch.close() +// ... +m := <-ch or { + println('channel has been closed') +} + +// propagate error +y := <-ch2 ? +``` + +#### Channel Select + +The `select` command allows monitoring several channels at the same time +without noticeable CPU load. It consists of a list of possible transfers and associated branches +of statements - similar to the [match](#match) command: +```v +import time + +fn main() { + ch := chan f64{} + ch2 := chan f64{} + ch3 := chan f64{} + mut b := 0.0 + c := 1.0 + // ... setup go threads that will send on ch/ch2 + go fn (the_channel chan f64) { + time.sleep(5 * time.millisecond) + the_channel <- 1.0 + }(ch) + go fn (the_channel chan f64) { + time.sleep(1 * time.millisecond) + the_channel <- 1.0 + }(ch2) + go fn (the_channel chan f64) { + _ := <-the_channel + }(ch3) + // + select { + a := <-ch { + // do something with `a` + eprintln('> a: $a') + } + b = <-ch2 { + // do something with predeclared variable `b` + eprintln('> b: $b') + } + ch3 <- c { + // do something if `c` was sent + time.sleep(5 * time.millisecond) + eprintln('> c: $c was send on channel ch3') + } + 500 * time.millisecond { + // do something if no channel has become ready within 0.5s + eprintln('> more than 0.5s passed without a channel being ready') + } + } + eprintln('> done') +} +``` + +The timeout branch is optional. If it is absent `select` waits for an unlimited amount of time. +It is also possible to proceed immediately if no channel is ready in the moment `select` is called +by adding an `else { ... }` branch. `else` and `> timeout` are mutually exclusive. + +The `select` command can be used as an *expression* of type `bool` +that becomes `false` if all channels are closed: +```v wip +if select { + ch <- a { + // ... + } +} { + // channel was open +} else { + // channel is closed +} +``` + +#### Special Channel Features + +For special purposes there are some builtin properties and methods: +```v +struct Abc { + x int +} + +a := 2.13 +ch := chan f64{} +res := ch.try_push(a) // try to perform `ch <- a` +println(res) +l := ch.len // number of elements in queue +c := ch.cap // maximum queue length +is_closed := ch.closed // bool flag - has `ch` been closed +println(l) +println(c) +mut b := Abc{} +ch2 := chan Abc{} +res2 := ch2.try_pop(mut b) // try to perform `b = <-ch2` +``` + +The `try_push/pop()` methods will return immediately with one of the results +`.success`, `.not_ready` or `.closed` - dependent on whether the object has been transferred or +the reason why not. +Usage of these methods and properties in production is not recommended - +algorithms based on them are often subject to race conditions. Especially `.len` and +`.closed` should not be used to make decisions. +Use `or` branches, error propagation or `select` instead (see [Syntax and Usage](#syntax-and-usage) +and [Channel Select](#channel-select) above). + +### Shared Objects + +Data can be exchanged between a coroutine and the calling thread via a shared variable. +Such variables should be created as `shared` and passed to the coroutine as such, too. +The underlying `struct` contains a hidden *mutex* that allows locking concurrent access +using `rlock` for read-only and `lock` for read/write access. + +```v +struct St { +mut: + x int // data to shared +} + +fn (shared b St) g() { + lock b { + // read/modify/write b.x + } +} + +fn main() { + shared a := St{ + x: 10 + } + go a.g() + // ... + rlock a { + // read a.x + } +} +``` +Shared variables must be structs, arrays or maps. + +## Decoding JSON + +```v +import json + +struct Foo { + x int +} + +struct User { + // Adding a [required] attribute will make decoding fail, if that + // field is not present in the input. + // If a field is not [required], but is missing, it will be assumed + // to have its default value, like 0 for numbers, or '' for strings, + // and decoding will not fail. + name string [required] + age int + // Use the `skip` attribute to skip certain fields + foo Foo [skip] + // If the field name is different in JSON, it can be specified + last_name string [json: lastName] +} + +data := '{ "name": "Frodo", "lastName": "Baggins", "age": 25 }' +user := json.decode(User, data) or { + eprintln('Failed to decode json, error: $err') + return +} +println(user.name) +println(user.last_name) +println(user.age) +// You can also decode JSON arrays: +sfoos := '[{"x":123},{"x":456}]' +foos := json.decode([]Foo, sfoos) ? +println(foos[0].x) +println(foos[1].x) +``` + +Because of the ubiquitous nature of JSON, support for it is built directly into V. + +The `json.decode` function takes two arguments: +the first is the type into which the JSON value should be decoded and +the second is a string containing the JSON data. + +V generates code for JSON encoding and decoding. +No runtime reflection is used. This results in much better performance. + +## Testing + +### Asserts + +```v +fn foo(mut v []int) { + v[0] = 1 +} + +mut v := [20] +foo(mut v) +assert v[0] < 4 +``` +An `assert` statement checks that its expression evaluates to `true`. If an assert fails, +the program will abort. Asserts should only be used to detect programming errors. When an +assert fails it is reported to *stderr*, and the values on each side of a comparison operator +(such as `<`, `==`) will be printed when possible. This is useful to easily find an +unexpected value. Assert statements can be used in any function. + +### Test files + +```v +// hello.v +module main + +fn hello() string { + return 'Hello world' +} + +fn main() { + println(hello()) +} +``` + +```v failcompile +module main + +// hello_test.v +fn test_hello() { + assert hello() == 'Hello world' +} +``` +To run the test above, use `v hello_test.v`. This will check that the function `hello` is +producing the correct output. V executes all test functions in the file. + +* All test functions have to be inside a test file whose name ends in `_test.v`. +* Test function names must begin with `test_` to mark them for execution. +* Normal functions can also be defined in test files, and should be called manually. Other + symbols can also be defined in test files e.g. types. +* There are two kinds of tests: external and internal. +* Internal tests must *declare* their module, just like all other .v +files from the same module. Internal tests can even call private functions in +the same module. +* External tests must *import* the modules which they test. They do not +have access to the private functions/types of the modules. They can test only +the external/public API that a module provides. + +In the example above, `test_hello` is an internal test, that can call +the private function `hello()` because `hello_test.v` has `module main`, +just like `hello.v`, i.e. both are part of the same module. Note also that +since `module main` is a regular module like the others, internal tests can +be used to test private functions in your main program .v files too. + +You can also define special test functions in a test file: +* `testsuite_begin` which will be run *before* all other test functions. +* `testsuite_end` which will be run *after* all other test functions. + +If a test function has an error return type, any propagated errors will fail the test: + +```v +import strconv + +fn test_atoi() ? { + assert strconv.atoi('1') ? == 1 + assert strconv.atoi('one') ? == 1 // test will fail +} +``` + +#### Running tests + +To run test functions in an individual test file, use `v foo_test.v`. + +To test an entire module, use `v test mymodule`. You can also use `v test .` to test +everything inside your current folder (and subfolders). You can pass the `-stats` +option to see more details about the individual tests run. + +You can put additional test data, including .v source files in a folder, named +`testdata`, right next to your _test.v files. V's test framework will *ignore* +such folders, while scanning for tests to run. This is usefull, if you want to +put .v files with invalid V source code, or other tests, including known +failing ones, that should be run in a specific way/options by a parent _test.v +file. + +NB: the path to the V compiler, is available through @VEXE, so a _test.v +file, can easily run *other* test files like this: +```v oksyntax +import os + +fn test_subtest() { + res := os.execute('${@VEXE} other_test.v') + assert res.exit_code == 1 + assert res.output.contains('other_test.v does not exist') +} +``` + +## Memory management + +V avoids doing unnecessary allocations in the first place by using value types, +string buffers, promoting a simple abstraction-free code style. + +Most objects (~90-100%) are freed by V's autofree engine: the compiler inserts +necessary free calls automatically during compilation. Remaining small percentage +of objects is freed via reference counting. + +The developer doesn't need to change anything in their code. "It just works", like in +Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for +each object. + +### Control + +You can take advantage of V's autofree engine and define a `free()` method on custom +data types: + +```v +struct MyType {} + +[unsafe] +fn (data &MyType) free() { + // ... +} +``` + +Just as the compiler frees C data types with C's `free()`, it will statically insert +`free()` calls for your data type at the end of each variable's lifetime. + +For developers willing to have more low level control, autofree can be disabled with +`-manualfree`, or by adding a `[manualfree]` on each function that wants manage its +memory manually. (See [attributes](#attributes)). + +_Note: right now autofree is hidden behind the -autofree flag. It will be enabled by +default in V 0.3. If autofree is not used, V programs will leak memory._ + +### Examples + +```v +import strings + +fn draw_text(s string, x int, y int) { + // ... +} + +fn draw_scene() { + // ... + name1 := 'abc' + name2 := 'def ghi' + draw_text('hello $name1', 10, 10) + draw_text('hello $name2', 100, 10) + draw_text(strings.repeat(`X`, 10000), 10, 50) + // ... +} +``` + +The strings don't escape `draw_text`, so they are cleaned up when +the function exits. + +In fact, with the `-prealloc` flag, the first two calls won't result in any allocations at all. +These two strings are small, so V will use a preallocated buffer for them. + +```v +struct User { + name string +} + +fn test() []int { + number := 7 // stack variable + user := User{} // struct allocated on stack + numbers := [1, 2, 3] // array allocated on heap, will be freed as the function exits + println(number) + println(user) + println(numbers) + numbers2 := [4, 5, 6] // array that's being returned, won't be freed here + return numbers2 +} +``` + +### Stack and Heap +#### Stack and Heap Basics + +Like with most other programming languages there are two locations where data can +be stored: + +* The *stack* allows fast allocations with almost zero administrative overhead. The + stack grows and shrinks with the function call depth – so every called + function has its stack segment that remains valid until the function returns. + No freeing is necessary, however, this also means that a reference to a stack + object becomes invalid on function return. Furthermore stack space is + limited (typically to a few Megabytes per thread). +* The *heap* is a large memory area (typically some Gigabytes) that is administrated + by the operating system. Heap objects are allocated and freed by special function + calls that delegate the administrative tasks to the OS. This means that they can + remain valid across several function calls, however, the administration is + expensive. + +#### V's default approach + +Due to performance considerations V tries to put objects on the stack if possible +but allocates them on the heap when obviously necessary. Example: + +```v +struct MyStruct { + n int +} + +struct RefStruct { + r &MyStruct +} + +fn main() { + q, w := f() + println('q: $q.r.n, w: $w.n') +} + +fn f() (RefStruct, &MyStruct) { + a := MyStruct{ + n: 1 + } + b := MyStruct{ + n: 2 + } + c := MyStruct{ + n: 3 + } + e := RefStruct{ + r: &b + } + x := a.n + c.n + println('x: $x') + return e, &c +} +``` + +Here `a` is stored on the stack since it's address never leaves the function `f()`. +However a reference to `b` is part of `e` which is returned. Also a reference to +`c` is returned. For this reason `b` and `c` will be heap allocated. + +Things become less obvious when a reference to an object is passed as function argument: + +```v +struct MyStruct { +mut: + n int +} + +fn main() { + mut q := MyStruct{ + n: 7 + } + w := MyStruct{ + n: 13 + } + x := q.f(&w) // references of `q` and `w` are passed + println('q: $q\nx: $x') +} + +fn (mut a MyStruct) f(b &MyStruct) int { + a.n += b.n + x := a.n * b.n + return x +} +``` +Here the call `q.f(&w)` passes references to `q` and `w` because `a` is +`mut` and `b` is of type `&MyStruct` in `f()`'s declaration, so technically +these references are leaving `main()`. However the *lifetime* of these +references lies inside the scope of `main()` so `q` and `w` are allocated +on the stack. + +#### Manual Control for Stack and Heap + +In the last example the V compiler could put `q` and `w` on the stack +because it assumed that in the call `q.f(&w)` these references were only +used for reading and modifying the referred values – and not to pass the +references themselves somewhere else. This can be seen in a way that the +references to `q` and `w` are only *borrowed* to `f()`. + +Things become different if `f()` is doing something with a reference itself: + +```v +struct RefStruct { +mut: + r &MyStruct +} + +// see discussion below +[heap] +struct MyStruct { + n int +} + +fn main() { + m := MyStruct{} + mut r := RefStruct{ + r: &m + } + r.g() + println('r: $r') +} + +fn (mut r RefStruct) g() { + s := MyStruct{ + n: 7 + } + r.f(&s) // reference to `s` inside `r` is passed back to `main() ` +} + +fn (mut r RefStruct) f(s &MyStruct) { + r.r = s // would trigger error without `[heap]` +} +``` + +Here `f()` looks quite innocent but is doing nasty things – it inserts a +reference to `s` into `r`. The problem with this is that `s` lives only as long +as `g()` is running but `r` is used in `main()` after that. For this reason +the compiler would complain about the assignment in `f()` because `s` *"might +refer to an object stored on stack"*. The assumption made in `g()` that the call +`r.f(&s)` would only borrow the reference to `s` is wrong. + +A solution to this dilemma is the `[heap]` attribute at the declaration of +`struct MyStruct`. It instructs the compiler to *always* allocate `MyStruct`-objects +on the heap. This way the reference to `s` remains valid even after `g()` returns. +The compiler takes into consideration that `MyStruct` objects are always heap +allocated when checking `f()` and allows assigning the reference to `s` to the +`r.r` field. + +There is a pattern often seen in other programming languages: + +```v failcompile +fn (mut a MyStruct) f() &MyStruct { + // do something with a + return &a // would return address of borrowed object +} +``` + +Here `f()` is passed a reference `a` as receiver that is passed back to the caller and returned +as result at the same time. The intention behind such a declaration is method chaining like +`y = x.f().g()`. However, the problem with this approach is that a second reference +to `a` is created – so it is not only borrowed and `MyStruct` has to be +declared as `[heap]`. + +In V the better approach is: + +```v +struct MyStruct { +mut: + n int +} + +fn (mut a MyStruct) f() { + // do something with `a` +} + +fn (mut a MyStruct) g() { + // do something else with `a` +} + +fn main() { + x := MyStruct{} // stack allocated + mut y := x + y.f() + y.g() + // instead of `mut y := x.f().g() +} +``` + +This way the `[heap]` attribute can be avoided – resulting in better performance. + +However, stack space is very limited as mentioned above. For this reason the `[heap]` +attribute might be suitable for very large structures even if not required by use cases +like those mentioned above. + +There is an alternative way to manually control allocation on a case to case basis. This +approach is not recommended but shown here for the sake of completeness: + +```v +struct MyStruct { + n int +} + +struct RefStruct { +mut: + r &MyStruct +} + +// simple function - just to overwrite stack segment previously used by `g()` +fn use_stack() { + x := 7.5 + y := 3.25 + z := x + y + println('$x $y $z') +} + +fn main() { + m := MyStruct{} + mut r := RefStruct{ + r: &m + } + r.g() + use_stack() // to erase invalid stack contents + println('r: $r') +} + +fn (mut r RefStruct) g() { + s := &MyStruct{ // `s` explicitly refers to a heap object + n: 7 + } + // change `&MyStruct` -> `MyStruct` above and `r.f(s)` -> `r.f(&s)` below + // to see data in stack segment being overwritten + r.f(s) +} + +fn (mut r RefStruct) f(s &MyStruct) { + r.r = unsafe { s } // override compiler check +} +``` + +Here the compiler check is suppressed by the `unsafe` block. To make `s` be heap +allocated even without `[heap]` attribute the `struct` literal is prefixed with +an ampersand: `&MyStruct{...}`. + +This last step would not be required by the compiler but without it the reference +inside `r` becomes invalid (the memory area pointed to will be overwritten by +`use_stack()`) and the program might crash (or at least produce an unpredictable +final output). That's why this approach is *unsafe* and should be avoided! + +## ORM + +(This is still in an alpha state) + +V has a built-in ORM (object-relational mapping) which supports SQLite, MySQL and Postgres, +but soon it will support MS SQL and Oracle. + +V's ORM provides a number of benefits: + +- One syntax for all SQL dialects. (Migrating between databases becomes much easier.) +- Queries are constructed using V's syntax. (There's no need to learn another syntax.) +- Safety. (All queries are automatically sanitised to prevent SQL injection.) +- Compile time checks. (This prevents typos which can only be caught during runtime.) +- Readability and simplicity. (You don't need to manually parse the results of a query and + then manually construct objects from the parsed results.) + +```v +import sqlite + +struct Customer { + // struct name has to be the same as the table name (for now) + id int [primary; sql: serial] // a field named `id` of integer type must be the first field + name string [nonull] + nr_orders int + country string [nonull] +} + +db := sqlite.connect('customers.db') ? + +// you can create tables +// CREATE TABLE IF NOT EXISTS `Customer` (`id` INTEGER PRIMARY KEY, `name` TEXT NOT NULL, `nr_orders` INTEGER, `country` TEXT NOT NULL) +sql db { + create table Customer +} + +// select count(*) from Customer +nr_customers := sql db { + select count from Customer +} +println('number of all customers: $nr_customers') +// V syntax can be used to build queries +uk_customers := sql db { + select from Customer where country == 'uk' && nr_orders > 0 +} +println(uk_customers.len) +for customer in uk_customers { + println('$customer.id - $customer.name') +} +// by adding `limit 1` we tell V that there will be only one object +customer := sql db { + select from Customer where id == 1 limit 1 +} +println('$customer.id - $customer.name') +// insert a new customer +new_customer := Customer{ + name: 'Bob' + nr_orders: 10 +} +sql db { + insert new_customer into Customer +} +``` + +For more examples and the docs, see       vlib/orm. + +## Writing Documentation + +The way it works is very similar to Go. It's very simple: there's no need to +write documentation separately for your code, +vdoc will generate it from docstrings in the source code. + +Documentation for each function/type/const must be placed right before the declaration: + +```v +// clearall clears all bits in the array +fn clearall() { +} +``` + +The comment must start with the name of the definition. + +Sometimes one line isn't enough to explain what a function does, in that case comments should +span to the documented function using single line comments: + +```v +// copy_all recursively copies all elements of the array by their value, +// if `dupes` is false all duplicate values are eliminated in the process. +fn copy_all(dupes bool) { + // ... +} +``` + +By convention it is preferred that comments are written in *present tense*. + +An overview of the module must be placed in the first comment right after the module's name. + +To generate documentation use vdoc, for example `v doc net.http`. + +## Tools + +### v fmt + +You don't need to worry about formatting your code or setting style guidelines. +`v fmt` takes care of that: + +```shell +v fmt file.v +``` + +It's recommended to set up your editor, so that `v fmt -w` runs on every save. +A vfmt run is usually pretty cheap (takes <30ms). + +Always run `v fmt -w file.v` before pushing your code. + +### Profiling + +V has good support for profiling your programs: `v -profile profile.txt run file.v` +That will produce a profile.txt file, which you can then analyze. + +The generated profile.txt file will have lines with 4 columns: +a) how many times a function was called +b) how much time in total a function took (in ms) +c) how much time on average, a call to a function took (in ns) +d) the name of the v function + +You can sort on column 3 (average time per function) using: +`sort -n -k3 profile.txt|tail` + +You can also use stopwatches to measure just portions of your code explicitly: +```v +import time + +fn main() { + sw := time.new_stopwatch() + println('Hello world') + println('Greeting the world took: ${sw.elapsed().nanoseconds()}ns') +} +``` + +# Advanced Topics + +## Dumping expressions at runtime +You can dump/trace the value of any V expression using `dump(expr)`. +For example, save this code sample as `factorial.v`, then run it with +`v run factorial.v`: +```v +fn factorial(n u32) u32 { + if dump(n <= 1) { + return dump(1) + } + return dump(n * factorial(n - 1)) +} + +fn main() { + println(factorial(5)) +} +``` +You will get: +``` +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: false +[factorial.v:2] n <= 1: true +[factorial.v:3] 1: 1 +[factorial.v:5] n * factorial(n - 1): 2 +[factorial.v:5] n * factorial(n - 1): 6 +[factorial.v:5] n * factorial(n - 1): 24 +[factorial.v:5] n * factorial(n - 1): 120 +120 +``` +Note that `dump(expr)` will trace both the source location, +the expression itself, and the expression value. + +## Memory-unsafe code + +Sometimes for efficiency you may want to write low-level code that can potentially +corrupt memory or be vulnerable to security exploits. V supports writing such code, +but not by default. + +V requires that any potentially memory-unsafe operations are marked intentionally. +Marking them also indicates to anyone reading the code that there could be +memory-safety violations if there was a mistake. + +Examples of potentially memory-unsafe operations are: + +* Pointer arithmetic +* Pointer indexing +* Conversion to pointer from an incompatible type +* Calling certain C functions, e.g. `free`, `strlen` and `strncmp`. + +To mark potentially memory-unsafe operations, enclose them in an `unsafe` block: + +```v wip +// allocate 2 uninitialized bytes & return a reference to them +mut p := unsafe { malloc(2) } +p[0] = `h` // Error: pointer indexing is only allowed in `unsafe` blocks +unsafe { + p[0] = `h` // OK + p[1] = `i` +} +p++ // Error: pointer arithmetic is only allowed in `unsafe` blocks +unsafe { + p++ // OK +} +assert *p == `i` +``` + +Best practice is to avoid putting memory-safe expressions inside an `unsafe` block, +so that the reason for using `unsafe` is as clear as possible. Generally any code +you think is memory-safe should not be inside an `unsafe` block, so the compiler +can verify it. + +If you suspect your program does violate memory-safety, you have a head start on +finding the cause: look at the `unsafe` blocks (and how they interact with +surrounding code). + +* Note: This is work in progress. + +### Structs with reference fields + +Structs with references require explicitly setting the initial value to a +reference value unless the struct already defines its own initial value. + +Zero-value references, or nil pointers, will **NOT** be supported in the future, +for now data structures such as Linked Lists or Binary Trees that rely on reference +fields that can use the value `0`, understanding that it is unsafe, and that it can +cause a panic. + +```v +struct Node { + a &Node + b &Node = 0 // Auto-initialized to nil, use with caution! +} + +// Reference fields must be initialized unless an initial value is declared. +// Zero (0) is OK but use with caution, it's a nil pointer. +foo := Node{ + a: 0 +} +bar := Node{ + a: &foo +} +baz := Node{ + a: 0 + b: 0 +} +qux := Node{ + a: &foo + b: &bar +} +println(baz) +println(qux) +``` + +## sizeof and __offsetof + +* `sizeof(Type)` gives the size of a type in bytes. +* `__offsetof(Struct, field_name)` gives the offset in bytes of a struct field. + +```v +struct Foo { + a int + b int +} + +assert sizeof(Foo) == 8 +assert __offsetof(Foo, a) == 0 +assert __offsetof(Foo, b) == 4 +``` + +## Calling C from V + +### Example + +```v +#flag -lsqlite3 +#include "sqlite3.h" +// See also the example from https://www.sqlite.org/quickstart.html +struct C.sqlite3 { +} + +struct C.sqlite3_stmt { +} + +type FnSqlite3Callback = fn (voidptr, int, &&char, &&char) int + +fn C.sqlite3_open(&char, &&C.sqlite3) int + +fn C.sqlite3_close(&C.sqlite3) int + +fn C.sqlite3_column_int(stmt &C.sqlite3_stmt, n int) int + +// ... you can also just define the type of parameter and leave out the C. prefix +fn C.sqlite3_prepare_v2(&C.sqlite3, &char, int, &&C.sqlite3_stmt, &&char) int + +fn C.sqlite3_step(&C.sqlite3_stmt) + +fn C.sqlite3_finalize(&C.sqlite3_stmt) + +fn C.sqlite3_exec(db &C.sqlite3, sql &char, cb FnSqlite3Callback, cb_arg voidptr, emsg &&char) int + +fn C.sqlite3_free(voidptr) + +fn my_callback(arg voidptr, howmany int, cvalues &&char, cnames &&char) int { + unsafe { + for i in 0 .. howmany { + print('| ${cstring_to_vstring(cnames[i])}: ${cstring_to_vstring(cvalues[i]):20} ') + } + } + println('|') + return 0 +} + +fn main() { + db := &C.sqlite3(0) // this means `sqlite3* db = 0` + // passing a string literal to a C function call results in a C string, not a V string + C.sqlite3_open(c'users.db', &db) + // C.sqlite3_open(db_path.str, &db) + query := 'select count(*) from users' + stmt := &C.sqlite3_stmt(0) + // NB: you can also use the `.str` field of a V string, + // to get its C style zero terminated representation + C.sqlite3_prepare_v2(db, &char(query.str), -1, &stmt, 0) + C.sqlite3_step(stmt) + nr_users := C.sqlite3_column_int(stmt, 0) + C.sqlite3_finalize(stmt) + println('There are $nr_users users in the database.') + // + error_msg := &char(0) + query_all_users := 'select * from users' + rc := C.sqlite3_exec(db, &char(query_all_users.str), my_callback, voidptr(7), &error_msg) + if rc != C.SQLITE_OK { + eprintln(unsafe { cstring_to_vstring(error_msg) }) + C.sqlite3_free(error_msg) + } + C.sqlite3_close(db) +} +``` + +## Calling V from C + +Since V can compile to C, calling V code from C is very easy. + +By default all V functions have the following naming scheme in C: `[module name]__[fn_name]`. + +For example, `fn foo() {}` in module `bar` will result in `bar__foo()`. + +To use a custom export name, use the `[export]` attribute: + +``` +[export: 'my_custom_c_name'] +fn foo() { +} +``` + + +## Atomics + +V has no special support for atomics, yet, nevertheless it's possible to treat variables as atomics +by calling C functions from V. The standard C11 atomic functions like `atomic_store()` are usually +defined with the help of macros and C compiler magic to provide a kind of *overloaded C functions*. +Since V does not support overloading functions by intention there are wrapper functions defined in +C headers named `atomic.h` that are part of the V compiler infrastructure. + +There are dedicated wrappers for all unsigned integer types and for pointers. +(`byte` is not fully supported on Windows) – the function names include the type name +as suffix. e.g. `C.atomic_load_ptr()` or `C.atomic_fetch_add_u64()`. + +To use these functions the C header for the used OS has to be included and the functions +that are intended to be used have to be declared. Example: + +```v globals +$if windows { + #include "@VEXEROOT/thirdparty/stdatomic/win/atomic.h" +} $else { + #include "@VEXEROOT/thirdparty/stdatomic/nix/atomic.h" +} + +// declare functions we want to use - V does not parse the C header +fn C.atomic_store_u32(&u32, u32) +fn C.atomic_load_u32(&u32) u32 +fn C.atomic_compare_exchange_weak_u32(&u32, &u32, u32) bool +fn C.atomic_compare_exchange_strong_u32(&u32, &u32, u32) bool + +const num_iterations = 10000000 + +// see section "Global Variables" below +__global ( + atom u32 // ordinary variable but used as atomic +) + +fn change() int { + mut races_won_by_change := 0 + for { + mut cmp := u32(17) // addressable value to compare with and to store the found value + // atomic version of `if atom == 17 { atom = 23 races_won_by_change++ } else { cmp = atom }` + if C.atomic_compare_exchange_strong_u32(&atom, &cmp, 23) { + races_won_by_change++ + } else { + if cmp == 31 { + break + } + cmp = 17 // re-assign because overwritten with value of atom + } + } + return races_won_by_change +} + +fn main() { + C.atomic_store_u32(&atom, 17) + t := go change() + mut races_won_by_main := 0 + mut cmp17 := u32(17) + mut cmp23 := u32(23) + for i in 0 .. num_iterations { + // atomic version of `if atom == 17 { atom = 23 races_won_by_main++ }` + if C.atomic_compare_exchange_strong_u32(&atom, &cmp17, 23) { + races_won_by_main++ + } else { + cmp17 = 17 + } + desir := if i == num_iterations - 1 { u32(31) } else { u32(17) } + // atomic version of `for atom != 23 {} atom = desir` + for !C.atomic_compare_exchange_weak_u32(&atom, &cmp23, desir) { + cmp23 = 23 + } + } + races_won_by_change := t.wait() + atom_new := C.atomic_load_u32(&atom) + println('atom: $atom_new, #exchanges: ${races_won_by_main + races_won_by_change}') + // prints `atom: 31, #exchanges: 10000000`) + println('races won by\n- `main()`: $races_won_by_main\n- `change()`: $races_won_by_change') +} +``` + +In this example both `main()` and the spawned thread `change()` try to replace a value of `17` +in the global `atom` with a value of `23`. The replacement in the opposite direction is +done exactly 10000000 times. The last replacement will be with `31` which makes the spawned +thread finish. + +It is not predictable how many replacements occur in which thread, but the sum will always +be 10000000. (With the non-atomic commands from the comments the value will be higher or the program +will hang – dependent on the compiler optimization used.) + +## Global Variables + +By default V does not allow global variables. However, in low level applications they have their +place so their usage can be enabled with the compiler flag `-enable-globals`. +Declarations of global variables must be surrounded with a `__global ( ... )` +specification – as in the example [above](#atomics). + +An initializer for global variables must be explicitly converted to the +desired target type. If no initializer is given a default initialization is done. +Some objects like semaphores and mutexes require an explicit initialization *in place*, i.e. +not with a value returned from a function call but with a method call by reference. +A separate `init()` function can be used for this purpose – it will be called before `main()`: + +```v globals +import sync + +__global ( + sem sync.Semaphore // needs initialization in `init()` + mtx sync.RwMutex // needs initialization in `init()` + f1 = f64(34.0625) // explicily initialized + shmap shared map[string]f64 // initialized as empty `shared` map + f2 f64 // initialized to `0.0` +) + +fn init() { + sem.init(0) + mtx.init() +} +``` +Be aware that in multi threaded applications the access to global variables is subject +to race conditions. There are several approaches to deal with these: + +- use `shared` types for the variable declarations and use `lock` blocks for access. + This is most appropriate for larger objects like structs, arrays or maps. +- handle primitive data types as "atomics" using special C-functions (see [above](#atomics)). +- use explicit synchronization primitives like mutexes to control access. The compiler + cannot really help in this case, so you have to know what you are doing. +- don't care – this approach is possible but makes only sense if the exact values + of global variables do not really matter. An example can be found in the `rand` module + where global variables are used to generate (non cryptographic) pseudo random numbers. + In this case data races lead to random numbers in different threads becoming somewhat + correlated, which is acceptable considering the performance penalty that using + synchonization primitives would represent. + +### Passing C compilation flags + +Add `#flag` directives to the top of your V files to provide C compilation flags like: + +- `-I` for adding C include files search paths +- `-l` for adding C library names that you want to get linked +- `-L` for adding C library files search paths +- `-D` for setting compile time variables + +You can (optionally) use different flags for different targets. +Currently the `linux`, `darwin` , `freebsd`, and `windows` flags are supported. + +NB: Each flag must go on its own line (for now) + +```v oksyntax +#flag linux -lsdl2 +#flag linux -Ivig +#flag linux -DCIMGUI_DEFINE_ENUMS_AND_STRUCTS=1 +#flag linux -DIMGUI_DISABLE_OBSOLETE_FUNCTIONS=1 +#flag linux -DIMGUI_IMPL_API= +``` + +In the console build command, you can use: +* `-cflags` to pass custom flags to the backend C compiler. +* `-cc` to change the default C backend compiler. +* For example: `-cc gcc-9 -cflags -fsanitize=thread`. + +You can define a `VFLAGS` environment variable in your terminal to store your `-cc` +and `-cflags` settings, rather than including them in the build command each time. + +### #pkgconfig + +Add `#pkgconfig` directive is used to tell the compiler which modules should be used for compiling +and linking using the pkg-config files provided by the respective dependencies. + +As long as backticks can't be used in `#flag` and spawning processes is not desirable for security +and portability reasons, V uses its own pkgconfig library that is compatible with the standard +freedesktop one. + +If no flags are passed it will add `--cflags` and `--libs`, both lines below do the same: + +```v oksyntax +#pkgconfig r_core +#pkgconfig --cflags --libs r_core +``` + +The `.pc` files are looked up into a hardcoded list of default pkg-config paths, the user can add +extra paths by using the `PKG_CONFIG_PATH` environment variable. Multiple modules can be passed. + +To check the existance of a pkg-config use `$pkgconfig('pkg')` as a compile time if condition to +check if a pkg-config exists. If it exists the branch will be created. Use `$else` or `$else $if` +to handle other cases. + +```v ignore +$if $pkgconfig('mysqlclient') { + #pkgconfig mysqlclient +} $else $if $pkgconfig('mariadb') { + #pkgconfig mariadb +} +``` + +### Including C code + +You can also include C code directly in your V module. +For example, let's say that your C code is located in a folder named 'c' inside your module folder. +Then: + +* Put a v.mod file inside the toplevel folder of your module (if you +created your module with `v new` you already have v.mod file). For +example: +```v ignore +Module { + name: 'mymodule', + description: 'My nice module wraps a simple C library.', + version: '0.0.1' + dependencies: [] +} +``` + + +* Add these lines to the top of your module: +```v oksyntax +#flag -I @VMODROOT/c +#flag @VMODROOT/c/implementation.o +#include "header.h" +``` +NB: @VMODROOT will be replaced by V with the *nearest parent folder, where there is a v.mod file*. +Any .v file beside or below the folder where the v.mod file is, +can use `#flag @VMODROOT/abc` to refer to this folder. +The @VMODROOT folder is also *prepended* to the module lookup path, +so you can *import* other modules under your @VMODROOT, by just naming them. + +The instructions above will make V look for an compiled .o file in +your module `folder/c/implementation.o`. +If V finds it, the .o file will get linked to the main executable, that used the module. +If it does not find it, V assumes that there is a `@VMODROOT/c/implementation.c` file, +and tries to compile it to a .o file, then will use that. + +This allows you to have C code, that is contained in a V module, so that its distribution is easier. +You can see a complete minimal example for using C code in a V wrapper module here: +[project_with_c_code](https://github.com/vlang/v/tree/master/vlib/v/tests/project_with_c_code). +Another example, demonstrating passing structs from C to V and back again: +[interoperate between C to V to C](https://github.com/vlang/v/tree/master/vlib/v/tests/project_with_c_code_2). + +### C types + +Ordinary zero terminated C strings can be converted to V strings with +`unsafe { &char(cstring).vstring() }` or if you know their length already with +`unsafe { &char(cstring).vstring_with_len(len) }`. + +NB: The .vstring() and .vstring_with_len() methods do NOT create a copy of the `cstring`, +so you should NOT free it after calling the method `.vstring()`. +If you need to make a copy of the C string (some libc APIs like `getenv` pretty much require that, +since they return pointers to internal libc memory), you can use `cstring_to_vstring(cstring)`. + +On Windows, C APIs often return so called `wide` strings (utf16 encoding). +These can be converted to V strings with `string_from_wide(&u16(cwidestring))` . + +V has these types for easier interoperability with C: + +- `voidptr` for C's `void*`, +- `&byte` for C's `byte*` and +- `&char` for C's `char*`. +- `&&char` for C's `char**` + +To cast a `voidptr` to a V reference, use `user := &User(user_void_ptr)`. + +`voidptr` can also be dereferenced into a V struct through casting: `user := User(user_void_ptr)`. + +[an example of a module that calls C code from V](https://github.com/vlang/v/blob/master/vlib/v/tests/project_with_c_code/mod1/wrapper.v) + +### C Declarations + +C identifiers are accessed with the `C` prefix similarly to how module-specific +identifiers are accessed. Functions must be redeclared in V before they can be used. +Any C types may be used behind the `C` prefix, but types must be redeclared in V in +order to access type members. + +To redeclare complex types, such as in the following C code: + +```c +struct SomeCStruct { + uint8_t implTraits; + uint16_t memPoolData; + union { + struct { + void* data; + size_t size; + }; + + DataView view; + }; +}; +``` + +members of sub-data-structures may be directly declared in the containing struct as below: + +```v +struct C.SomeCStruct { + implTraits byte + memPoolData u16 + // These members are part of sub data structures that can't currently be represented in V. + // Declaring them directly like this is sufficient for access. + // union { + // struct { + data voidptr + size size_t + // } + view C.DataView + // } +} +``` + +The existence of the data members is made known to V, and they may be used without +re-creating the original structure exactly. + +Alternatively, you may [embed](#embedded-structs) the sub-data-structures to maintain +a parallel code structure. + +## Debugging + +### C Backend binaries (Default) + +To debug issues in the generated binary (flag: `-b c`), you can pass these flags: + +- `-g` - produces a less optimized executable with more debug information in it. + V will enforce line numbers from the .v files in the stacktraces, that the + executable will produce on panic. It is usually better to pass -g, unless + you are writing low level code, in which case use the next option `-cg`. +- `-cg` - produces a less optimized executable with more debug information in it. + The executable will use C source line numbers in this case. It is frequently + used in combination with `-keepc`, so that you can inspect the generated + C program in case of panic, or so that your debugger (`gdb`, `lldb` etc.) + can show you the generated C source code. +- `-showcc` - prints the C command that is used to build the program. +- `-show-c-output` - prints the output, that your C compiler produced + while compiling your program. +- `-keepc` - do not delete the generated C source code file after a successful + compilation. Also keep using the same file path, so it is more stable, + and easier to keep opened in an editor/IDE. + +For best debugging experience if you are writing a low level wrapper for an existing +C library, you can pass several of these flags at the same time: +`v -keepc -cg -showcc yourprogram.v`, then just run your debugger (gdb/lldb) or IDE +on the produced executable `yourprogram`. + +If you just want to inspect the generated C code, +without further compilation, you can also use the `-o` flag (e.g. `-o file.c`). +This will make V produce the `file.c` then stop. + +If you want to see the generated C source code for *just* a single C function, +for example `main`, you can use: `-printfn main -o file.c`. + +To debug the V executable itself you need to compile from src with `./v -g -o v cmd/v`. + +You can debug tests with for example `v -g -keepc prog_test.v`. The `-keepc` flag is needed, +so that the executable is not deleted, after it was created and ran. + +To see a detailed list of all flags that V supports, +use `v help`, `v help build` and `v help build-c`. + +**Commandline Debugging** + +1. compile your binary with debugging info `v -g hello.v` +2. debug with [lldb](https://lldb.llvm.org) or [GDB](https://www.gnu.org/software/gdb/) e.g. `lldb hello` + +Troubleshooting (debugging) executables [created with V in GDB](https://github.com/vlang/v/wiki/Troubleshooting-(debugging)-executables-created-with-V-in-GDB) + +**Visual debugging Setup:** +* [Visual Studio Code](vscode.md) + +### Native Backend binaries + +Currently there is no debugging support for binaries, created by the +native backend (flag: `-b native`). + +### Javascript Backend + +To debug the generated Javascript output you can active source maps: +`v -b js -sourcemap hello.v -o hello.js` + +For all supported options check the latest help: +`v help build-js` + +## Conditional compilation + +### Compile time code + +`$` is used as a prefix for compile-time operations. + +#### `$if` condition +```v +// Support for multiple conditions in one branch +$if ios || android { + println('Running on a mobile device!') +} +$if linux && x64 { + println('64-bit Linux.') +} +// Usage as expression +os := $if windows { 'Windows' } $else { 'UNIX' } +println('Using $os') +// $else-$if branches +$if tinyc { + println('tinyc') +} $else $if clang { + println('clang') +} $else $if gcc { + println('gcc') +} $else { + println('different compiler') +} +$if test { + println('testing') +} +// v -cg ... +$if debug { + println('debugging') +} +// v -prod ... +$if prod { + println('production build') +} +// v -d option ... +$if option ? { + println('custom option') +} +``` + +If you want an `if` to be evaluated at compile time it must be prefixed with a `$` sign. +Right now it can be used to detect an OS, compiler, platform or compilation options. +`$if debug` is a special option like `$if windows` or `$if x32`. +If you're using a custom ifdef, then you do need `$if option ? {}` and compile with`v -d option`. +Full list of builtin options: +| OS | Compilers | Platforms | Other | +| --- | --- | --- | --- | +| `windows`, `linux`, `macos` | `gcc`, `tinyc` | `amd64`, `arm64` | `debug`, `prod`, `test` | +| `mac`, `darwin`, `ios`, | `clang`, `mingw` | `x64`, `x32` | `js`, `glibc`, `prealloc` | +| `android`,`mach`, `dragonfly` | `msvc` | `little_endian` | `no_bounds_checking`, `freestanding` | +| `gnu`, `hpux`, `haiku`, `qnx` | `cplusplus` | `big_endian` | +| `solaris` | | | | + +#### `$embed_file` + +```v ignore +import os +fn main() { + embedded_file := $embed_file('v.png') + os.write_file('exported.png', embedded_file.to_string()) ? +} +``` + +V can embed arbitrary files into the executable with the `$embed_file()` +compile time call. Paths can be absolute or relative to the source file. + +When you do not use `-prod`, the file will not be embedded.

These files can contain JS. code. +- `.c.v` => will be used only by the C backend. These files can contain C. code. +- `.native.v` => will be used only by V's native backend. +- `_nix.c.v` => will be used only on Unix systems (non Windows). +- `_${os}.c.v` => will be used only on the specific `os` system. +For example, `_windows.c.v` will be used only when compiling on Windows, or with `-os windows`. +- `_default.c.v` => will be used only if there is NOT a more specific platform file. +For example, if you have both `file_linux.c.v` and `file_default.c.v`, +and you are compiling for linux, then only `file_linux.c.v` will be used, +and `file_default.c.v` will be ignored. + +Here is a more complete example: +main.v: +```v ignore +module main +fn main() { println(message) } +``` + +main_default.c.v: +```v ignore +module main +const ( message = 'Hello world' ) +``` + +main_linux.c.v: +```v ignore +module main +const ( message = 'Hello linux' ) +``` + +main_windows.c.v: +```v ignore +module main +const ( message = 'Hello windows' ) +``` + +With the example above: +- when you compile for windows, you will get 'Hello windows' +- when you compile for linux, you will get 'Hello linux' +- when you compile for any other platform, you will get the +non specific 'Hello world' message. + +- `_d_customflag.v` => will be used *only* if you pass `-d customflag` to V. +That corresponds to `$if customflag ? {}`, but for a whole file, not just a +single block. `customflag` should be a snake_case identifier, it can not +contain arbitrary characters (only lower case latin letters + numbers + `_`). +NB: a combinatorial `_d_customflag_linux.c.v` postfix will not work. +If you do need a custom flag file, that has platform dependent code, use the +postfix `_d_customflag.v`, and then use plaftorm dependent compile time +conditional blocks inside it, i.e. `$if linux {}` etc. + +- `_notd_customflag.v` => similar to _d_customflag.v, but will be used +*only* if you do NOT pass `-d customflag` to V. + +## Compile time pseudo variables + +V also gives your code access to a set of pseudo string variables, +that are substituted at compile time: + +- `@FN` => replaced with the name of the current V function +- `@METHOD` => replaced with ReceiverType.MethodName +- `@MOD` => replaced with the name of the current V module +- `@STRUCT` => replaced with the name of the current V struct +- `@FILE` => replaced with the path of the V source file +- `@LINE` => replaced with the V line number where it appears (as a string). +- `@COLUMN` => replaced with the column where it appears (as a string). +- `@VEXE` => replaced with the path to the V compiler +- `@VEXEROOT` => will be substituted with the *folder*, + where the V executable is (as a string). +- `@VHASH` => replaced with the shortened commit hash of the V compiler (as a string). +- `@VMOD_FILE` => replaced with the contents of the nearest v.mod file (as a string). +- `@VMODROOT` => will be substituted with the *folder*, + where the nearest v.mod file is (as a string). + +That allows you to do the following example, useful while debugging/logging/tracing your code: +```v +eprintln('file: ' + @FILE + ' | line: ' + @LINE + ' | fn: ' + @MOD + '.' + @FN) +``` + +Another example, is if you want to embed the version/name from v.mod *inside* your executable: +```v ignore +import v.vmod +vm := vmod.decode( @VMOD_FILE ) or { panic(err.msg) } +eprintln('$vm.name $vm.version\n $vm.description') +``` + +## Performance tuning + +The generated C code is usually fast enough, when you compile your code +with `-prod`. There are some situations though, where you may want to give +additional hints to the compiler, so that it can further optimize some +blocks of code. + +NB: These are *rarely* needed, and should not be used, unless you +*profile your code*, and then see that there are significant benefits for them. +To cite gcc's documentation: "programmers are notoriously bad at predicting +how their programs actually perform". + +`[inline]` - you can tag functions with `[inline]`, so the C compiler will +try to inline them, which in some cases, may be beneficial for performance, +but may impact the size of your executable. + +`[direct_array_access]` - in functions tagged with `[direct_array_access]` +the compiler will translate array operations directly into C array operations - +omiting bounds checking. This may save a lot of time in a function that iterates +over an array but at the cost of making the function unsafe - unless +the boundaries will be checked by the user. + +`if _likely_(bool expression) {` this hints the C compiler, that the passed +boolean expression is very likely to be true, so it can generate assembly +code, with less chance of branch misprediction. In the JS backend, +that does nothing. + +`if _unlikely_(bool expression) {` similar to `_likely_(x)`, but it hints that +the boolean expression is highly improbable. In the JS backend, that does nothing. + + + +## Compile-time reflection + +Having built-in JSON support is nice, but V also allows you to create efficient +serializers for any data format. V has compile-time `if` and `for` constructs: + +```v wip +// TODO: not fully implemented + +struct User { + name string + age int +} + +// Note: T should be passed a struct name only +fn decode(data string) T { + mut result := T{} + // compile-time `for` loop + // T.fields gives an array of a field metadata type + $for field in T.fields { + $if field.typ is string { + // $(string_expr) produces an identifier + result.$(field.name) = get_string(data, field.name) + } $else $if field.typ is int { + result.$(field.name) = get_int(data, field.name) + } + } + return result +} + +// `decode` generates: +fn decode_User(data string) User { + mut result := User{} + result.name = get_string(data, 'name') + result.age = get_int(data, 'age') + return result +} +``` + +## Limited operator overloading + +```v +struct Vec { + x int + y int +} + +fn (a Vec) str() string { + return '{$a.x, $a.y}' +} + +fn (a Vec) + (b Vec) Vec { + return Vec{a.x + b.x, a.y + b.y} +} + +fn (a Vec) - (b Vec) Vec { + return Vec{a.x - b.x, a.y - b.y} +} + +fn main() { + a := Vec{2, 3} + b := Vec{4, 5} + mut c := Vec{1, 2} + println(a + b) // "{6, 8}" + println(a - b) // "{-2, -2}" + c += a + println(c) // "{3, 5}" +} +``` + +Operator overloading goes against V's philosophy of simplicity and predictability. +But since scientific and graphical applications are among V's domains, +operator overloading is an important feature to have in order to improve readability: + +`a.add(b).add(c.mul(d))` is a lot less readable than `a + b + c * d`. + +To improve safety and maintainability, operator overloading is limited: + +- It's only possible to overload `+, -, *, /, %, <, >, ==, !=, <=, >=` operators. +- `==` and `!=` are self generated by the compiler but can be overriden. +- Calling other functions inside operator functions is not allowed. +- Operator functions can't modify their arguments. +- When using `<` and `==` operators, the return type must be `bool`. +- `!=`, `>`, `<=` and `>=` are auto generated when `==` and `<` are defined. +- Both arguments must have the same type (just like with all operators in V). +- Assignment operators (`*=`, `+=`, `/=`, etc) +are auto generated when the operators are defined though they must return the same type. + +## Inline assembly + +```v ignore +a := 100 +b := 20 +mut c := 0 +asm amd64 { + mov eax, a + add eax, b + mov c, eax + ; =r (c) as c // output + ; r (a) as a // input + r (b) as b +} +println('a: $a') // 100 +println('b: $b') // 20 +println('c: $c') // 120 +``` + +For more examples, see [github.com/vlang/v/tree/master/vlib/v/tests/assembly/asm_test.amd64.v](https://github.com/vlang/v/tree/master/vlib/v/tests/assembly/asm_test.amd64.v) + +## Translating C to V + +TODO: translating C to V will be available in V 0.3. + +V can translate your C code to human readable V code and generate V wrappers on top of C libraries. + + +Let's create a simple program `test.c` first: + +```c +#include "stdio.h" + +int main() { + for (int i = 0; i < 10; i++) { + printf("hello world\n"); + } + return 0; +} +``` + +Run `v translate test.c`, and V will generate `test.v`: + +```v +fn main() { + for i := 0; i < 10; i++ { + println('hello world') + } +} +``` + +To generate a wrapper on top of a C library use this command: + +```bash +v wrapper c_code/libsodium/src/libsodium +``` + +This will generate a directory `libsodium` with a V module. + +Example of a C2V generated libsodium wrapper: + +https://github.com/medvednikov/libsodium + +
      + +When should you translate C code and when should you simply call C code from V? + +If you have well-written, well-tested C code, +then of course you can always simply call this C code from V. + +Translating it to V gives you several advantages: + +- If you plan to develop that code base, you now have everything in one language, + which is much safer and easier to develop in than C. +- Cross-compilation becomes a lot easier.

This works even +when compiling GUI apps using the `ui` module or graphical apps using `gg`. + +You will need to install Clang, LLD linker, and download a zip file with +libraries and include files for Windows and Linux. V will provide you with a link. + +## Cross-platform shell scripts in V + +V can be used as an alternative to Bash to write deployment scripts, build scripts, etc. + +The advantage of using V for this is the simplicity and predictability of the language, and +cross-platform support. "V scripts" run on Unix-like systems as well as on Windows. + +Use the `.vsh` file extension. It will make all functions in the `os` +module global (so that you can use `mkdir()` instead of `os.mkdir()`, for example). + +An example `deploy.vsh`: +```v wip +#!/usr/bin/env -S v run +// The shebang above associates the file to V on Unix-like systems, +// so it can be run just by specifying the path to the file +// once it's made executable using `chmod +x`. + +// Remove if build/ exits, ignore any errors if it doesn't +rmdir_all('build') or { } + +// Create build/, never fails as build/ does not exist +mkdir('build') ? + +// Move *.v files to build/ +result := exec('mv *.v build/') ? +if result.exit_code != 0 { + println(result.output) +} +// Similar to: +// files := ls('.') ? +// mut count := 0 +// if files.len > 0 { +// for file in files { +// if file.ends_with('.v') { +// mv(file, 'build/') or { +// println('err: $err') +// return +// } +// } +// count++ +// } +// } +// if count == 0 { +// println('No files') +// } +``` + +Now you can either compile this like a normal V program and get an executable you can deploy and run +anywhere: +`v deploy.vsh && ./deploy` + +Or just run it more like a traditional Bash script: +`v run deploy.vsh` + +On Unix-like platforms, the file can be run directly after making it executable using `chmod +x`: +`./deploy.vsh` + +## Attributes + +V has several attributes that modify the behavior of functions and structs. + +An attribute is a compiler instruction specified inside `[]` right before a +function/struct/enum declaration and applies only to the following declaration. + +```v +// Calling this function will result in a deprecation warning +[deprecated] +fn old_function() { +} + +// It can also display a custom deprecation message +[deprecated: 'use new_function() instead'] +fn legacy_function() {} + +// This function's calls will be inlined. +[inline] +fn inlined_function() { +} + +// This function's calls will NOT be inlined. +[noinline] +fn function() { +} + +// This function will NOT return to its callers. +// Such functions can be used at the end of or blocks, +// just like exit/1 or panic/1.

However in simple and obvious cases the necessary lock/unlock +can be generated automatically for `array`/`map` operations: + +```v ignore +shared a := []int{cap: 5} +go h2(shared a) +a << 3 +// keep in mind that `h2()` could change `a` between these statements +a << 4 +x := a[1] // not necessarily `4` + +shared b := map[string]int{} +go h3(shared b) +b['apple'] = 3 +c['plume'] = 7 +y := b['apple'] // not necesarily `3` + +// iteration over elements +for k, v in b { + // concurrently changed k/v pairs may or my not be included +} +``` + +This is handy, but since other coroutines might access the `array`/`map` +concurrently between the automatically locked statements, the results +are sometimes surprising. Each statement should be seen as a single +transaction that is unrelated to the previous or following +statement. Therefore - but also for performance reasons - it's often +better to group consecutive coherent statements in an explicit `lock` block. + +### Channels diff --git a/v_windows/v/old/doc/vscode.md b/v_windows/v/old/doc/vscode.md new file mode 100644 index 0000000..e1e1b35 --- /dev/null +++ b/v_windows/v/old/doc/vscode.md @@ -0,0 +1,107 @@ +# Visual Studio Code Setup + +## Table of Contents + +* [V language support](#v-language-support) +* [Visual Debugging](#visual-debugging) + +## V language support + +The [V VS Code Extention](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang) +provides V language support for Visual Studio Code. + +![Screenshot Code with activated extention](https://github.com/vlang/vscode-vlang/raw/HEAD/images/demo.png) + +**Features:** +* Syntax Highlighting. +* Code Snippets for quick coding. +* Format code on file save as well as format manually (using v fmt). +* Linter (Workspace files only). +[more](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang) + +**Hint:** This extention will not add the V compiler!

With this she closed her eyes and died. + +The girl went out to her mother's grave every day and wept, and she remained +pious and good. When winter came the snow spread a white cloth over the grave, +and when the spring sun had removed it again, the man took himself another +wife. + +This wife brought two daughters into the house with her. They were beautiful, +with fair faces, but evil and dark hearts. Times soon grew very bad for the +poor stepchild. + +"Why should that stupid goose sit in the parlor with us?" they said. "If she +wants to eat bread, then she will have to earn it. Out with this kitchen maid!" + +They took her beautiful clothes away from her, dressed her in an old gray +smock, and gave her wooden shoes. "Just look at the proud princess! How decked +out she is!" they shouted and laughed as they led her into the kitchen. + +There she had to do hard work from morning until evening, get up before +daybreak, carry water, make the fires, cook, and wash. Besides this, the +sisters did everything imaginable to hurt her. They made fun of her, scattered +peas and lentils into the ashes for her, so that she had to sit and pick them +out again. In the evening when she had worked herself weary, there was no bed +for her. Instead she had to sleep by the hearth in the ashes. And because she +always looked dusty and dirty, they called her Cinderella. + +One day it happened that the father was going to the fair, and he asked his two +stepdaughters what he should bring back for them. + +"Beautiful dresses," said the one. + +"Pearls and jewels," said the other. + +"And you, Cinderella," he said, "what do you want?" + +"Father, break off for me the first twig that brushes against your hat on your +way home." + +So he bought beautiful dresses, pearls, and jewels for his two stepdaughters. +On his way home, as he was riding through a green thicket, a hazel twig brushed +against him and knocked off his hat. Then he broke off the twig and took it +with him. Arriving home, he gave his stepdaughters the things that they had +asked for, and he gave Cinderella the twig from the hazel bush. + +Cinderella thanked him, went to her mother's grave, and planted the branch on +it, and she wept so much that her tears fell upon it and watered it. It grew +and became a beautiful tree. + +Cinderella went to this tree three times every day, and beneath it she wept and +prayed. A white bird came to the tree every time, and whenever she expressed a +wish, the bird would throw down to her what she had wished for. + +Now it happened that the king proclaimed a festival that was to last three +days. All the beautiful young girls in the land were invited, so that his son +could select a bride for himself. When the two stepsisters heard that they too +had been invited, they were in high spirits. + +They called Cinderella, saying, "Comb our hair for us. Brush our shoes and +fasten our buckles. We are going to the festival at the king's castle." + +Cinderella obeyed, but wept, because she too would have liked to go to the +dance with them. She begged her stepmother to allow her to go. + +"You, Cinderella?" she said. "You, all covered with dust and dirt, and you want +to go to the festival?. You have neither clothes nor shoes, and yet you want to +dance!" + +However, because Cinderella kept asking, the stepmother finally said, "I have +scattered a bowl of lentils into the ashes for you. If you can pick them out +again in two hours, then you may go with us." + +The girl went through the back door into the garden, and called out, "You tame +pigeons, you turtledoves, and all you birds beneath the sky, come and help me +to gather: + +The good ones go into the pot, The bad ones go into your crop." Two white +pigeons came in through the kitchen window, and then the turtledoves, and +finally all the birds beneath the sky came whirring and swarming in, and lit +around the ashes. The pigeons nodded their heads and began to pick, pick, pick, +pick. And the others also began to pick, pick, pick, pick. They gathered all +the good grains into the bowl. Hardly one hour had passed before they were +finished, and they all flew out again. The girl took the bowl to her +stepmother, and was happy, thinking that now she would be allowed to go to the +festival with them. + +But the stepmother said, "No, Cinderella, you have no clothes, and you don't +know how to dance. Everyone would only laugh at you." + +Cinderella began to cry, and then the stepmother said, "You may go if you are +able to pick two bowls of lentils out of the ashes for me in one hour," +thinking to herself, "She will never be able to do that." + +The girl went through the back door into the garden, and called out, "You tame +pigeons, you turtledoves, and all you birds beneath the sky, come and help me +to gather: + +The good ones go into the pot, The bad ones go into your crop." Two white +pigeons came in through the kitchen window, and then the turtledoves, and +finally all the birds beneath the sky came whirring and swarming in, and lit +around the ashes. The pigeons nodded their heads and began to pick, pick, pick, +pick. And the others also began to pick, pick, pick, pick. They gathered all +the good grains into the bowls. Before a half hour had passed they were +finished, and they all flew out again. The girl took the bowls to her +stepmother, and was happy, thinking that now she would be allowed to go to the +festival with them. + +But the stepmother said, "It's no use. You are not coming with us, for you have +no clothes, and you don't know how to dance. We would be ashamed of you." With +this she turned her back on Cinderella, and hurried away with her two proud +daughters. + +Now that no one else was at home, Cinderella went to her mother's grave beneath +the hazel tree, and cried out: + +Shake and quiver, little tree, Throw gold and silver down to me. Then the bird +threw a gold and silver dress down to her, and slippers embroidered with silk +and silver. She quickly put on the dress and went to the festival. Her +stepsisters and her stepmother did not recognize her. They thought she must be +a foreign princess, for she looked so beautiful in the golden dress. They never +once thought it was Cinderella, for they thought that she was sitting at home +in the dirt, looking for lentils in the ashes. + +The prince approached her, took her by the hand, and danced with her. +Furthermore, he would dance with no one else. He never let go of her hand, and +whenever anyone else came and asked her to dance, he would say, "She is my +dance partner." + +She danced until evening, and then she wanted to go home. But the prince said, +"I will go along and escort you," for he wanted to see to whom the beautiful +girl belonged. However, she eluded him and jumped into the pigeon coop. The +prince waited until her father came, and then he told him that the unknown girl +had jumped into the pigeon coop. + +The old man thought, "Could it be Cinderella?" + +He had them bring him an ax and a pick so that he could break the pigeon coop +apart, but no one was inside. When they got home Cinderella was lying in the +ashes, dressed in her dirty clothes. A dim little oil-lamp was burning in the +fireplace. Cinderella had quickly jumped down from the back of the pigeon coop +and had run to the hazel tree. There she had taken off her beautiful clothes +and laid them on the grave, and the bird had taken them away again. Then, +dressed in her gray smock, she had returned to the ashes in the kitchen. + +The next day when the festival began anew, and her parents and her stepsisters +had gone again, Cinderella went to the hazel tree and said: + +Shake and quiver, little tree, Throw gold and silver down to me. Then the bird +threw down an even more magnificent dress than on the preceding day. When +Cinderella appeared at the festival in this dress, everyone was astonished at +her beauty. The prince had waited until she came, then immediately took her by +the hand, and danced only with her. When others came and asked her to dance +with them, he said, "She is my dance partner." When evening came she wanted to +leave, and the prince followed her, wanting to see into which house she went. +But she ran away from him and into the garden behind the house. A beautiful +tall tree stood there, on which hung the most magnificent pears. She climbed as +nimbly as a squirrel into the branches, and the prince did not know where she +had gone. He waited until her father came, then said to him, "The unknown girl +has eluded me, and I believe she has climbed up the pear tree. + +The father thought, "Could it be Cinderella?" He had an ax brought to him and +cut down the tree, but no one was in it. When they came to the kitchen, +Cinderella was lying there in the ashes as usual, for she had jumped down from +the other side of the tree, had taken the beautiful dress back to the bird in +the hazel tree, and had put on her gray smock. + +On the third day, when her parents and sisters had gone away, Cinderella went +again to her mother's grave and said to the tree: + +Shake and quiver, little tree, Throw gold and silver down to me. This time the +bird threw down to her a dress that was more splendid and magnificent than any +she had yet had, and the slippers were of pure gold. When she arrived at the +festival in this dress, everyone was so astonished that they did not know what +to say. The prince danced only with her, and whenever anyone else asked her to +dance, he would say, "She is my dance partner." When evening came Cinderella +wanted to leave, and the prince tried to escort her, but she ran away from him +so quickly that he could not follow her. The prince, however, had set a trap. +He had had the entire stairway smeared with pitch. When she ran down the +stairs, her left slipper stuck in the pitch. The prince picked it up. It was +small and dainty, and of pure gold. + +The next morning, he went with it to the man, and said to him, "No one shall be +my wife except for the one whose foot fits this golden shoe." + +The two sisters were happy to hear this, for they had pretty feet. With her +mother standing by, the older one took the shoe into her bedroom to try it on. +She could not get her big toe into it, for the shoe was too small for her. Then +her mother gave her a knife and said, "Cut off your toe. When you are queen you +will no longer have to go on foot." + +The girl cut off her toe, forced her foot into the shoe, swallowed the pain, +and went out to the prince. He took her on his horse as his bride and rode away +with her. However, they had to ride past the grave, and there, on the hazel +tree, sat the two pigeons, crying out: + +Rook di goo, rook di goo! There's blood in the shoe. The shoe is too tight, +This bride is not right! Then he looked at her foot and saw how the blood was +running from it. He turned his horse around and took the false bride home +again, saying that she was not the right one, and that the other sister should +try on the shoe. She went into her bedroom, and got her toes into the shoe all +right, but her heel was too large. Then her mother gave her a knife, and said, +"Cut a piece off your heel. When you are queen you will no longer have to go on +foot." + +The girl cut a piece off her heel, forced her foot into the shoe, swallowed the +pain, and went out to the prince. He took her on his horse as his bride and +rode away with her. When they passed the hazel tree, the two pigeons were +sitting in it, and they cried out: + +Rook di goo, rook di goo! There's blood in the shoe. The shoe is too tight, +This bride is not right! He looked down at her foot and saw how the blood was +running out of her shoe, and how it had stained her white stocking all red. +Then he turned his horse around and took the false bride home again. "This is +not the right one, either," he said. "Don't you have another daughter?" + +"No," said the man. "There is only a deformed little Cinderella from my first +wife, but she cannot possibly be the bride." + +The prince told him to send her to him, but the mother answered, "Oh, no, she +is much too dirty. She cannot be seen." + +But the prince insisted on it, and they had to call Cinderella. She first +washed her hands and face clean, and then went and bowed down before the +prince, who gave her the golden shoe. She sat down on a stool, pulled her foot +out of the heavy wooden shoe, and put it into the slipper, and it fitted her +perfectly. + +When she stood up the prince looked into her face, and he recognized the +beautiful girl who had danced with him. He cried out, "She is my true bride." + +The stepmother and the two sisters were horrified and turned pale with anger. +The prince, however, took Cinderella onto his horse and rode away with her. As +they passed by the hazel tree, the two white pigeons cried out: + +Rook di goo, rook di goo! No blood's in the shoe. The shoe's not too tight, +This bride is right! After they had cried this out, they both flew down and +lit on Cinderella's shoulders, one on the right, the other on the left, and +remained sitting there. When the wedding with the prince was to be held, the +two false sisters came, wanting to gain favor with Cinderella and to share her +good fortune. When the bridal couple walked into the church, the older sister +walked on their right side and the younger on their left side, and the pigeons +pecked out one eye from each of them.

Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character.

+The text below is copied from the [original publication](http://developer.cybozu.co.jp/archives/kazuho/2009/08/picoev-a-tiny-e.html) + +I am sure many programmers writing network applications have their own abstracting layers hiding the differences between various I/O multiplex APIs, like select(2), poll(2), epoll(2), ... And of course, I am one among them. While writing mycached ([see Mycached: memcached protocol support for MySQL for more information](http://developer.cybozu.co.jp/archives/kazuho/2009/08/mycached-memcac.html)), I was at first considering of using [libev](http://software.schmorp.de/pkg/libev.html) for multiplexing socket I/Os. [Libevent](http://www.monkey.org/~provos/libevent/) was not an option since it does not (yet) provide multithreading support. + +But it was a great pain for me to learn how to use libev. I do not mean that its is an ugly product. In fact, I think that it is a very well written, excellent library. However, for me it was too much a boring task to learn how the things are abstracted, already being familiar with the problems it tries to hide. + +So instead I thought it might be a good occasion to write my own library that could be used in any programs I may write in the future. The result is picoev, and it is faster than libevent or libev! The benchmark used is a re-modified version taken from libev.schmorp.de/bench.html and can be found [here](http://coderepos.org/share/browser/lang/c/picoev/trunk/example/bench.c). +![setup time](http://developer.cybozu.co.jp/archives/kazuho/files/picoev_setup.png) +![event processing time](http://developer.cybozu.co.jp/archives/kazuho/files/picoev_event.png) + +Why is it faster? It is because it uses an array and a ring buffer of bit vectors as its internal structure. Libevent and libev seem to use some kind of sorted tree to represent file descriptors. However, if we concentrate on Un*x systems, there is a guarantee that the descriptors will be a small positive integer. Picoev utilizes the fact and stores information related to file descriptors (such as pointers to callback functions or callback arguments) in an array, resulting in a faster manipulation of socket states. + +Another optimization technique used by picoev is not to use an ordered tree for keeping timeout information. Generally speaking, most network applications do not require accurate timeouts. Thus it is possible to use a ring buffer (a sliding array) of bit vectors for the purpose. Each bit vector represents a set of file descriptors that time-outs at a given time. Picoev uses 128 of bit vectors to represent timeouts, for example, the first bit vector represents the sockets that timeout a second after, the second bit vector representing them of two seconds after..., and the bit vectors slide every second. If the maximum timeout required by the web application is greater than 128, the minimum granurality of timeout becomes two seconds. + +I would like to reiterate that both libevent and libev are great libraries. Picoev is not at comparable to them especially in maturity and the number of features. It only supports select(2), epoll(2), and kqueue(2) for the time being. However the design is simple than the other two, and I think it will be a good starting point to write network applications, or to use as a basis for writing one's own network libraries. + diff --git a/v_windows/v/old/thirdparty/picoev/src/picoev.h b/v_windows/v/old/thirdparty/picoev/src/picoev.h new file mode 100644 index 0000000..b00b02b --- /dev/null +++ b/v_windows/v/old/thirdparty/picoev/src/picoev.h @@ -0,0 +1,404 @@ +/* + * Copyright (c) 2009, Cybozu Labs, Inc. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * * Redistributions of source code must retain the above copyright notice, + * this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright notice, + * this list of conditions and the following disclaimer in the documentation + * and/or other materials provided with the distribution. + * * Neither the name of the nor the names of its contributors + * may be used to endorse or promote products derived from this software + * without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" + * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE + * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE + * ARE DISCLAIMED.

This + function is called very early, usually at the start of the + platform's entry function (e.g. main or WinMain). You should do as + little as possible here, since the rest of your code might be called + from another thread (this depends on the platform): + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + .width = 640, + .height = 480, + .init_cb = my_init_func, + .frame_cb = my_frame_func, + .cleanup_cb = my_cleanup_func, + .event_cb = my_event_func, + ... + }; + } + + There are many more setup parameters, but these are the most important. + For a complete list search for the sapp_desc structure declaration + below. + + DO NOT call any sokol-app function from inside sokol_main(), since + sokol-app will not be initialized at this point. + + The .width and .height parameters are the preferred size of the 3D + rendering canvas. The actual size may differ from this depending on + platform and other circumstances. Also the canvas size may change at + any time (for instance when the user resizes the application window, + or rotates the mobile device). + + All provided function callbacks will be called from the same thread, + but this may be different from the thread where sokol_main() was called. + + .init_cb (void (*)(void)) + This function is called once after the application window, + 3D rendering context and swap chain have been created. The + function takes no arguments and has no return value. + .frame_cb (void (*)(void)) + This is the per-frame callback, which is usually called 60 + times per second. This is where your application would update + most of its state and perform all rendering. + .cleanup_cb (void (*)(void)) + The cleanup callback is called once right before the application + quits. + .event_cb (void (*)(const sapp_event* event)) + The event callback is mainly for input handling, but is also + used to communicate other types of events to the application. Keep the + event_cb struct member zero-initialized if your application doesn't require + event handling. + .fail_cb (void (*)(const char* msg)) + The fail callback is called when a fatal error is encountered + during start which doesn't allow the program to continue. + Providing a callback here gives you a chance to show an error message + to the user. The default behaviour is SOKOL_LOG(msg) + + As you can see, those 'standard callbacks' don't have a user_data + argument, so any data that needs to be preserved between callbacks + must live in global variables. If keeping state in global variables + is not an option, there's an alternative set of callbacks with + an additional user_data pointer argument: + + .user_data (void*) + The user-data argument for the callbacks below + .init_userdata_cb (void (*)(void* user_data)) + .frame_userdata_cb (void (*)(void* user_data)) + .cleanup_userdata_cb (void (*)(void* user_data)) + .event_cb (void(*)(const sapp_event* event, void* user_data)) + .fail_cb (void(*)(const char* msg, void* user_data)) + These are the user-data versions of the callback functions. You + can mix those with the standard callbacks that don't have the + user_data argument. + + The function sapp_userdata() can be used to query the user_data + pointer provided in the sapp_desc struct. + + You can also call sapp_query_desc() to get a copy of the + original sapp_desc structure. + + NOTE that there's also an alternative compile mode where sokol_app.h + doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY. + + --- Implement the initialization callback function (init_cb), this is called + once after the rendering surface, 3D API and swap chain have been + initialized by sokol_app. All sokol-app functions can be called + from inside the initialization callback, the most useful functions + at this point are: + + int sapp_width(void) + int sapp_height(void) + Returns the current width and height of the default framebuffer in pixels, + this may change from one frame to the next, and it may be different + from the initial size provided in the sapp_desc struct. + + float sapp_widthf(void) + float sapp_heightf(void) + These are alternatives to sapp_width() and sapp_height() which return + the default framebuffer size as float values instead of integer. This + may help to prevent casting back and forth between int and float + in more strongly typed languages than C and C++. + + int sapp_color_format(void) + int sapp_depth_format(void) + The color and depth-stencil pixelformats of the default framebuffer, + as integer values which are compatible with sokol-gfx's + sg_pixel_format enum (so that they can be plugged directly in places + where sg_pixel_format is expected). Possible values are: + + 23 == SG_PIXELFORMAT_RGBA8 + 27 == SG_PIXELFORMAT_BGRA8 + 41 == SG_PIXELFORMAT_DEPTH + 42 == SG_PIXELFORMAT_DEPTH_STENCIL + + int sapp_sample_count(void) + Return the MSAA sample count of the default framebuffer. + + bool sapp_gles2(void) + Returns true if a GLES2 or WebGL context has been created. This + is useful when a GLES3/WebGL2 context was requested but is not + available so that sokol_app.h had to fallback to GLES2/WebGL. + + const void* sapp_metal_get_device(void) + const void* sapp_metal_get_renderpass_descriptor(void) + const void* sapp_metal_get_drawable(void) + If the Metal backend has been selected, these functions return pointers + to various Metal API objects required for rendering, otherwise + they return a null pointer. These void pointers are actually + Objective-C ids converted with a (ARC) __bridge cast so that + the ids can be tunnel through C code. Also note that the returned + pointers to the renderpass-descriptor and drawable may change from one + frame to the next, only the Metal device object is guaranteed to + stay the same. + + const void* sapp_macos_get_window(void) + On macOS, get the NSWindow object pointer, otherwise a null pointer. + Before being used as Objective-C object, the void* must be converted + back with a (ARC) __bridge cast. + + const void* sapp_ios_get_window(void) + On iOS, get the UIWindow object pointer, otherwise a null pointer. + Before being used as Objective-C object, the void* must be converted + back with a (ARC) __bridge cast. + + const void* sapp_win32_get_hwnd(void) + On Windows, get the window's HWND, otherwise a null pointer. The + HWND has been cast to a void pointer in order to be tunneled + through code which doesn't include Windows.h. + + const void* sapp_d3d11_get_device(void) + const void* sapp_d3d11_get_device_context(void) + const void* sapp_d3d11_get_render_target_view(void) + const void* sapp_d3d11_get_depth_stencil_view(void) + Similar to the sapp_metal_* functions, the sapp_d3d11_* functions + return pointers to D3D11 API objects required for rendering, + only if the D3D11 backend has been selected. Otherwise they + return a null pointer. Note that the returned pointers to the + render-target-view and depth-stencil-view may change from one + frame to the next! + + const void* sapp_wgpu_get_device(void) + const void* sapp_wgpu_get_render_view(void) + const void* sapp_wgpu_get_resolve_view(void) + const void* sapp_wgpu_get_depth_stencil_view(void) + These are the WebGPU-specific functions to get the WebGPU + objects and values required for rendering. If sokol_app.h + is not compiled with SOKOL_WGPU, these functions return null. + + const void* sapp_android_get_native_activity(void); + On Android, get the native activity ANativeActivity pointer, otherwise + a null pointer. + + --- Implement the frame-callback function, this function will be called + on the same thread as the init callback, but might be on a different + thread than the sokol_main() function. Note that the size of + the rendering framebuffer might have changed since the frame callback + was called last. Call the functions sapp_width() and sapp_height() + each frame to get the current size. + + --- Optionally implement the event-callback to handle input events. + sokol-app provides the following type of input events: + - a 'virtual key' was pressed down or released + - a single text character was entered (provided as UTF-32 code point) + - a mouse button was pressed down or released (left, right, middle) + - mouse-wheel or 2D scrolling events + - the mouse was moved + - the mouse has entered or left the application window boundaries + - low-level, portable multi-touch events (began, moved, ended, cancelled) + - the application window was resized, iconified or restored + - the application was suspended or restored (on mobile platforms) + - the user or application code has asked to quit the application + - a string was pasted to the system clipboard + - one or more files have been dropped onto the application window + + To explicitly 'consume' an event and prevent that the event is + forwarded for further handling to the operating system, call + sapp_consume_event() from inside the event handler (NOTE that + this behaviour is currently only implemented for some HTML5 + events, support for other platforms and event types will + be added as needed, please open a github ticket and/or provide + a PR if needed). + + NOTE: Do *not* call any 3D API rendering functions in the event + callback function, since the 3D API context may not be active when the + event callback is called (it may work on some platforms and 3D APIs, + but not others, and the exact behaviour may change between + sokol-app versions). + + --- Implement the cleanup-callback function, this is called once + after the user quits the application (see the section + "APPLICATION QUIT" for detailed information on quitting + behaviour, and how to intercept a pending quit - for instance to show a + "Really Quit?" dialog box). Note that the cleanup-callback isn't + guaranteed to be called on the web and mobile platforms. + + MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE) + ================================================ + In normal mouse mode, no mouse movement events are reported when the + mouse leaves the windows client area or hits the screen border (whether + it's one or the other depends on the platform), and the mouse move events + (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in + framebuffer pixels in the sapp_event items mouse_x and mouse_y, and + relative movement in framebuffer pixels in the sapp_event items mouse_dx + and mouse_dy. + + To get continuous mouse movement (also when the mouse leaves the window + client area or hits the screen border), activate mouse-lock mode + by calling: + + sapp_lock_mouse(true) + + When mouse lock is activated, the mouse pointer is hidden, the + reported absolute mouse position (sapp_event.mouse_x/y) appears + frozen, and the relative mouse movement in sapp_event.mouse_dx/dy + no longer has a direct relation to framebuffer pixels but instead + uses "raw mouse input" (what "raw mouse input" exactly means also + differs by platform). + + To deactivate mouse lock and return to normal mouse mode, call + + sapp_lock_mouse(false) + + And finally, to check if mouse lock is currently active, call + + if (sapp_mouse_locked()) { ... } + + On native platforms, the sapp_lock_mouse() and sapp_mouse_locked() + functions work as expected (mouse lock is activated or deactivated + immediately when sapp_lock_mouse() is called, and sapp_mouse_locked() + also immediately returns the new state after sapp_lock_mouse() + is called. + + On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave + differently, as dictated by the limitations of the HTML5 Pointer Lock API: + + - sapp_lock_mouse(true) can be called at any time, but it will + only take effect in a 'short-lived input event handler of a specific + type', meaning when one of the following events happens: + - SAPP_EVENTTYPE_MOUSE_DOWN + - SAPP_EVENTTYPE_MOUSE_UP + - SAPP_EVENTTYPE_MOUSE_SCROLL + - SAPP_EVENTYTPE_KEY_UP + - SAPP_EVENTTYPE_KEY_DOWN + - The mouse lock/unlock action on the web platform is asynchronous, + this means that sapp_mouse_locked() won't immediately return + the new status after calling sapp_lock_mouse(), instead the + reported status will only change when the pointer lock has actually + been activated or deactivated in the browser. + - On the web, mouse lock can be deactivated by the user at any time + by pressing the Esc key. When this happens, sokol_app.h behaves + the same as if sapp_lock_mouse(false) is called. + + For things like camera manipulation it's most straightforward to lock + and unlock the mouse right from the sokol_app.h event handler, for + instance the following code enters and leaves mouse lock when the + left mouse button is pressed and released, and then uses the relative + movement information to manipulate a camera (taken from the + cgltf-sapp.c sample in the sokol-samples repository + at https://github.com/floooh/sokol-samples): + + static void input(const sapp_event* ev) { + switch (ev->type) { + case SAPP_EVENTTYPE_MOUSE_DOWN: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(true); + } + break; + + case SAPP_EVENTTYPE_MOUSE_UP: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(false); + } + break; + + case SAPP_EVENTTYPE_MOUSE_MOVE: + if (sapp_mouse_locked()) { + cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f); + } + break; + + default: + break; + } + } + + CLIPBOARD SUPPORT + ================= + Applications can send and receive UTF-8 encoded text data from and to the + system clipboard. By default, clipboard support is disabled and + must be enabled at startup via the following sapp_desc struct + members: + + sapp_desc.enable_clipboard - set to true to enable clipboard support + sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes + + Enabling the clipboard will dynamically allocate a clipboard buffer + for UTF-8 encoded text data of the requested size in bytes, the default + size is 8 KBytes. Strings that don't fit into the clipboard buffer + (including the terminating zero) will be silently clipped, so it's + important that you provide a big enough clipboard size for your + use case. + + To send data to the clipboard, call sapp_set_clipboard_string() with + a pointer to an UTF-8 encoded, null-terminated C-string. + + NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be + called from inside a 'short-lived event handler', and there are a few + other HTML5-specific caveats to workaround. You'll basically have to + tinker until it works in all browsers :/ (maybe the situation will + improve when all browsers agree on and implement the new + HTML5 navigator.clipboard API). + + To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED + event in your event handler function, and then call sapp_get_clipboard_string() + to obtain the pasted UTF-8 encoded text. + + NOTE that behaviour of sapp_get_clipboard_string() is slightly different + depending on platform: + + - on the HTML5 platform, the internal clipboard buffer will only be updated + right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent, + and sapp_get_clipboard_string() will simply return the current content + of the clipboard buffer + - on 'native' platforms, the call to sapp_get_clipboard_string() will + update the internal clipboard buffer with the most recent data + from the system clipboard + + Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event, + and then call sapp_get_clipboard_string() right in the event handler. + + The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app + as follows: + + - on macOS: when the Cmd+V key is pressed down + - on HTML5: when the browser sends a 'paste' event to the global 'window' object + - on all other platforms: when the Ctrl+V key is pressed down + + DRAG AND DROP SUPPORT + ===================== + PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5 + and on the native desktop platforms (Win32, Linux and macOS) because + of security-related restrictions in the HTML5 drag'n'drop API. The + WASM/HTML5 specifics are described at the end of this documentation + section: + + Like clipboard support, drag'n'drop support must be explicitly enabled + at startup in the sapp_desc struct. + + sapp_desc sokol_main() { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + ... + }; + } + + You can also adjust the maximum number of files that are accepted + in a drop operation, and the maximum path length in bytes if needed: + + sapp_desc sokol_main() { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + .max_dropped_files = 8, // default is 1 + .max_dropped_file_path_length = 8192, // in bytes, default is 2048 + ... + }; + } + + When drag'n'drop is enabled, the event callback will be invoked with an + event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on + the application window. + + After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the + number of dropped files, and their absolute paths by calling separate + functions: + + void on_event(const sapp_event* ev) { + if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) { + + // the mouse position where the drop happened + float x = ev->mouse_x; + float y = ev->mouse_y; + + // get the number of files and their paths like this: + const int num_dropped_files = sapp_get_num_dropped_files(); + for (int i = 0; i < num_dropped_files; i++) { + const char* path = sapp_get_dropped_file_path(i); + ... + } + } + } + + The returned file paths are UTF-8 encoded strings. + + You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path() + anywhere, also outside the event handler callback, but be aware that the + file path strings will be overwritten with the next drop operation. + + In any case, sapp_get_dropped_file_path() will never return a null pointer, + instead an empty string "" will be returned if the drag'n'drop feature + hasn't been enabled, the last drop-operation failed, or the file path index + is out of range. + + Drag'n'drop caveats: + + - if more files are dropped in a single drop-action + than sapp_desc.max_dropped_files, the additional + files will be silently ignored + - if any of the file paths is longer than + sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8 + encoding) the entire drop operation will be silently ignored (this + needs some sort of error feedback in the future) + - no mouse positions are reported while the drag is in + process, this may change in the future + + Drag'n'drop on HTML5/WASM: + + The HTML5 drag'n'drop API doesn't return file paths, but instead + black-box 'file objects' which must be used to load the content + of dropped files. This is the reason why sokol_app.h adds two + HTML5-specific functions to the drag'n'drop API: + + uint32_t sapp_html5_get_dropped_file_size(int index) + Returns the size in bytes of a dropped file. + + void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request) + Asynchronously loads the content of a dropped file into a + provided memory buffer (which must be big enough to hold + the file content) + + To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED + event is received: + + sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){ + .dropped_file_index = 0, + .callback = fetch_cb + .buffer_ptr = buf, + .buffer_size = buf_size, + .user_data = ... + }); + + Make sure that the memory pointed to by 'buf' stays valid until the + callback function is called! + + As result of the asynchronous loading operation (no matter if succeeded or + failed) the 'fetch_cb' function will be called: + + void fetch_cb(const sapp_html5_fetch_response* response) { + // IMPORTANT: check if the loading operation actually succeeded: + if (response->succeeded) { + // the size of the loaded file: + const uint32_t num_bytes = response->fetched_size; + // and the pointer to the data (same as 'buf' in the fetch-call): + const void* ptr = response->buffer_ptr; + } + else { + // on error check the error code: + switch (response->error_code) { + case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL: + ... + break; + case SAPP_HTML5_FETCH_ERROR_OTHER: + ... + break; + } + } + } + + Check the droptest-sapp example for a real-world example which works + both on native platforms and the web: + + https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c + + HIGH-DPI RENDERING + ================== + You can set the sapp_desc.high_dpi flag during initialization to request + a full-resolution framebuffer on HighDPI displays. The default behaviour + is sapp_desc.high_dpi=false, this means that the application will + render to a lower-resolution framebuffer on HighDPI displays and the + rendered content will be upscaled by the window system composer. + + In a HighDPI scenario, you still request the same window size during + sokol_main(), but the framebuffer sizes returned by sapp_width() + and sapp_height() will be scaled up according to the DPI scaling + ratio. You can also get a DPI scaling factor with the function + sapp_dpi_scale(). + + Here's an example on a Mac with Retina display: + + sapp_desc sokol_main() { + return (sapp_desc) { + .width = 640, + .height = 480, + .high_dpi = true, + ... + }; + } + + The functions sapp_width(), sapp_height() and sapp_dpi_scale() will + return the following values: + + sapp_width -> 1280 + sapp_height -> 960 + sapp_dpi_scale -> 2.0 + + If the high_dpi flag is false, or you're not running on a Retina display, + the values would be: + + sapp_width -> 640 + sapp_height -> 480 + sapp_dpi_scale -> 1.0 + + APPLICATION QUIT + ================ + Without special quit handling, a sokol_app.h application will quit + 'gracefully' when the user clicks the window close-button unless a + platform's application model prevents this (e.g. on web or mobile). + 'Graceful exit' means that the application-provided cleanup callback will + be called before the application quits. + + On native desktop platforms sokol_app.h provides more control over the + application-quit-process. It's possible to initiate a 'programmatic quit' + from the application code, and a quit initiated by the application user can + be intercepted (for instance to show a custom dialog box). + + This 'programmatic quit protocol' is implemented through 3 functions + and 1 event: + + - sapp_quit(): This function simply quits the application without + giving the user a chance to intervene. Usually this might + be called when the user clicks the 'Ok' button in a 'Really Quit?' + dialog box + - sapp_request_quit(): Calling sapp_request_quit() will send the + event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler + callback, giving the user code a chance to intervene and cancel the + pending quit process (for instance to show a 'Really Quit?' dialog + box). If the event handler callback does nothing, the application + will be quit as usual. To prevent this, call the function + sapp_cancel_quit() from inside the event handler. + - sapp_cancel_quit(): Cancels a pending quit request, either initiated + by the user clicking the window close button, or programmatically + by calling sapp_request_quit(). The only place where calling this + function makes sense is from inside the event handler callback when + the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received. + - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user + clicks the window's close button or application code calls the + sapp_request_quit() function. The event handler callback code can handle + this event by calling sapp_cancel_quit() to cancel the quit. + If the event is ignored, the application will quit as usual. + + On the web platform, the quit behaviour differs from native platforms, + because of web-specific restrictions: + + A `programmatic quit` initiated by calling sapp_quit() or + sapp_request_quit() will work as described above: the cleanup callback is + called, platform-specific cleanup is performed (on the web + this means that JS event handlers are unregisters), and then + the request-animation-loop will be exited. However that's all. The + web page itself will continue to exist (e.g. it's not possible to + programmatically close the browser tab). + + On the web it's also not possible to run custom code when the user + closes a brower tab, so it's not possible to prevent this with a + fancy custom dialog box. + + Instead the standard "Leave Site?" dialog box can be activated (or + deactivated) with the following function: + + sapp_html5_ask_leave_site(bool ask); + + The initial state of the associated internal flag can be provided + at startup via sapp_desc.html5_ask_leave_site. + + This feature should only be used sparingly in critical situations - for + instance when the user would loose data - since popping up modal dialog + boxes is considered quite rude in the web world. Note that there's no way + to customize the content of this dialog box or run any code as a result + of the user's decision. Also note that the user must have interacted with + the site before the dialog box will appear. These are all security measures + to prevent fishing. + + The Dear ImGui HighDPI sample contains example code of how to + implement a 'Really Quit?' dialog box with Dear ImGui (native desktop + platforms only), and for showing the hardwired "Leave Site?" dialog box + when running on the web platform: + + https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html + + FULLSCREEN + ========== + If the sapp_desc.fullscreen flag is true, sokol-app will try to create + a fullscreen window on platforms with a 'proper' window system + (mobile devices will always use fullscreen). The implementation details + depend on the target platform, in general sokol-app will use a + 'soft approach' which doesn't interfere too much with the platform's + window system (for instance borderless fullscreen window instead of + a 'real' fullscreen mode). Such details might change over time + as sokol-app is adapted for different needs. + + The most important effect of fullscreen mode to keep in mind is that + the requested canvas width and height will be ignored for the initial + window size, calling sapp_width() and sapp_height() will instead return + the resolution of the fullscreen canvas (however the provided size + might still be used for the non-fullscreen window, in case the user can + switch back from fullscreen- to windowed-mode). + + To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen(). + + To check if the application window is currently in fullscreen mode, + call sapp_is_fullscreen(). + + ONSCREEN KEYBOARD + ================= + On some platforms which don't provide a physical keyboard, sokol-app + can display the platform's integrated onscreen keyboard for text + input. To request that the onscreen keyboard is shown, call + + sapp_show_keyboard(true); + + Likewise, to hide the keyboard call: + + sapp_show_keyboard(false); + + Note that on the web platform, the keyboard can only be shown from + inside an input handler. On such platforms, sapp_show_keyboard() + will only work as expected when it is called from inside the + sokol-app event callback function. When called from other places, + an internal flag will be set, and the onscreen keyboard will be + called at the next 'legal' opportunity (when the next input event + is handled). + + OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY) + ====================================================== + In its default configuration, sokol_app.h "hijacks" the platform's + standard main() function. This was done because different platforms + have different main functions which are not compatible with + C's main() (for instance WinMain on Windows has completely different + arguments). However, this "main hijacking" posed a problem for + usage scenarios like integrating sokol_app.h with other languages than + C or C++, so an alternative SOKOL_NO_ENTRY mode has been added + in which the user code provides the platform's main function: + + - define SOKOL_NO_ENTRY before including the sokol_app.h implementation + - do *not* provide a sokol_main() function + - instead provide the standard main() function of the platform + - from the main function, call the function ```sapp_run()``` which + takes a pointer to an ```sapp_desc``` structure. + - ```sapp_run()``` takes over control and calls the provided init-, frame-, + shutdown- and event-callbacks just like in the default model, it + will only return when the application quits (or not at all on some + platforms, like emscripten) + + NOTE: SOKOL_NO_ENTRY is currently not supported on Android. + + WINDOWS CONSOLE OUTPUT + ====================== + On Windows, regular windowed applications don't show any stdout/stderr text + output, which can be a bit of a hassle for printf() debugging or generally + logging text to the console. Also, console output by default uses a local + codepage setting and thus international UTF-8 encoded text is printed + as garbage. + + To help with these issues, sokol_app.h can be configured at startup + via the following Windows-specific sapp_desc flags: + + sapp_desc.win32_console_utf8 (default: false) + When set to true, the output console codepage will be switched + to UTF-8 (and restored to the original codepage on exit) + + sapp_desc.win32_console_attach (default: false) + When set to true, stdout and stderr will be attached to the + console of the parent process (if the parent process actually + has a console). This means that if the application was started + in a command line window, stdout and stderr output will be printed + to the terminal, just like a regular command line program. But if + the application is started via double-click, it will behave like + a regular UI application, and stdout/stderr will not be visible. + + sapp_desc.win32_console_create (default: false) + When set to true, a new console window will be created and + stdout/stderr will be redirected to that console window. It + doesn't matter if the application is started from the command + line or via double-click. + + TEMP NOTE DUMP + ============== + - onscreen keyboard support on Android requires Java :(, should we even bother? + - sapp_desc needs a bool whether to initialize depth-stencil surface + - GL context initialization needs more control (at least what GL version to initialize) + - application icon + - the UPDATE_CURSOR event currently behaves differently between Win32 and OSX + (Win32 sends the event each frame when the mouse moves and is inside the window + client area, OSX sends it only once when the mouse enters the client area) + - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy + at the latest but should do it earlier, in onStop, as an app is "killable" after onStop + on Android Honeycomb and later (it can't be done at the moment as the app may be started + again after onStop and the sokol lifecycle does not yet handle context teardown/bringup) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

Callback model: You provide a callback function, which will be called + when Sokol Audio needs new samples. On all platforms except emscripten, + this function is called from a separate thread. + 2. Push model: Your code pushes small blocks of sample data from your + main loop or a thread you created.

If you need a more fully-featured audio solution, check + out SoLoud, it's excellent: + + https://github.com/jarikomppa/soloud + + Another alternative which feature-wise is somewhere inbetween SoLoud and + sokol-audio might be MiniAudio: + + https://github.com/mackron/miniaudio + + GLOSSARY + ======== + - stream buffer: + The internal audio data buffer, usually provided by the backend API. The + size of the stream buffer defines the base latency, smaller buffers have + lower latency but may cause audio glitches. Bigger buffers reduce or + eliminate glitches, but have a higher base latency. + + - stream callback: + Optional callback function which is called by Sokol Audio when it + needs new samples. On Windows, macOS/iOS and Linux, this is called in + a separate thread, on WebAudio, this is called per-frame in the + browser thread. + + - channel: + A discrete track of audio data, currently 1-channel (mono) and + 2-channel (stereo) is supported and tested. + + - sample: + The magnitude of an audio signal on one channel at a given time. In + Sokol Audio, samples are 32-bit float numbers in the range -1.0 to + +1.0. + + - frame: + The tightly packed set of samples for all channels at a given time. + For mono 1 frame is 1 sample. For stereo, 1 frame is 2 samples. + + - packet: + In Sokol Audio, a small chunk of audio data that is moved from the + main thread to the audio streaming thread in order to decouple the + rate at which the main thread provides new audio data, and the + streaming thread consuming audio data. + + WORKING WITH SOKOL AUDIO + ======================== + First call saudio_setup() with your preferred audio playback options. + In most cases you can stick with the default values, these provide + a good balance between low-latency and glitch-free playback + on all audio backends. + + If you want to use the callback-model, you need to provide a stream + callback function either in saudio_desc.stream_cb or saudio_desc.stream_userdata_cb, + otherwise keep both function pointers zero-initialized. + + Use push model and default playback parameters: + + saudio_setup(&(saudio_desc){0}); + + Use stream callback model and default playback parameters: + + saudio_setup(&(saudio_desc){ + .stream_cb = my_stream_callback + }); + + The standard stream callback doesn't have a user data argument, if you want + that, use the alternative stream_userdata_cb and also set the user_data pointer: + + saudio_setup(&(saudio_desc){ + .stream_userdata_cb = my_stream_callback, + .user_data = &my_data + }); + + The following playback parameters can be provided through the + saudio_desc struct: + + General parameters (both for stream-callback and push-model): + + int sample_rate -- the sample rate in Hz, default: 44100 + int num_channels -- number of channels, default: 1 (mono) + int buffer_frames -- number of frames in streaming buffer, default: 2048 + + The stream callback prototype (either with or without userdata): + + void (*stream_cb)(float* buffer, int num_frames, int num_channels) + void (*stream_userdata_cb)(float* buffer, int num_frames, int num_channels, void* user_data) + Function pointer to the user-provide stream callback. + + Push-model parameters: + + int packet_frames -- number of frames in a packet, default: 128 + int num_packets -- number of packets in ring buffer, default: 64 + + The sample_rate and num_channels parameters are only hints for the audio + backend, it isn't guaranteed that those are the values used for actual + playback. + + To get the actual parameters, call the following functions after + saudio_setup(): + + int saudio_sample_rate(void) + int saudio_channels(void); + + It's unlikely that the number of channels will be different than requested, + but a different sample rate isn't uncommon. + + (NOTE: there's an yet unsolved issue when an audio backend might switch + to a different sample rate when switching output devices, for instance + plugging in a bluetooth headset, this case is currently not handled in + Sokol Audio). + + You can check if audio initialization was successful with + saudio_isvalid(). If backend initialization failed for some reason + (for instance when there's no audio device in the machine), this + will return false. Not checking for success won't do any harm, all + Sokol Audio function will silently fail when called after initialization + has failed, so apart from missing audio output, nothing bad will happen. + + Before your application exits, you should call + + saudio_shutdown(); + + This stops the audio thread (on Linux, Windows and macOS/iOS) and + properly shuts down the audio backend. + + THE STREAM CALLBACK MODEL + ========================= + To use Sokol Audio in stream-callback-mode, provide a callback function + like this in the saudio_desc struct when calling saudio_setup(): + + void stream_cb(float* buffer, int num_frames, int num_channels) { + ... + } + + Or the alternative version with a user-data argument: + + void stream_userdata_cb(float* buffer, int num_frames, int num_channels, void* user_data) { + my_data_t* my_data = (my_data_t*) user_data; + ... + } + + The job of the callback function is to fill the *buffer* with 32-bit + float sample values. + + To output silence, fill the buffer with zeros: + + void stream_cb(float* buffer, int num_frames, int num_channels) { + const int num_samples = num_frames * num_channels; + for (int i = 0; i < num_samples; i++) { + buffer[i] = 0.0f; + } + } + + For stereo output (num_channels == 2), the samples for the left + and right channel are interleaved: + + void stream_cb(float* buffer, int num_frames, int num_channels) { + assert(2 == num_channels); + for (int i = 0; i < num_frames; i++) { + buffer[2*i + 0] = ...; // left channel + buffer[2*i + 1] = ...; // right channel + } + } + + Please keep in mind that the stream callback function is running in a + separate thread, if you need to share data with the main thread you need + to take care yourself to make the access to the shared data thread-safe! + + THE PUSH MODEL + ============== + To use the push-model for providing audio data, simply don't set (keep + zero-initialized) the stream_cb field in the saudio_desc struct when + calling saudio_setup(). + + To provide sample data with the push model, call the saudio_push() + function at regular intervals (for instance once per frame). You can + call the saudio_expect() function to ask Sokol Audio how much room is + in the ring buffer, but if you provide a continuous stream of data + at the right sample rate, saudio_expect() isn't required (it's a simple + way to sync/throttle your sample generation code with the playback + rate though). + + With saudio_push() you may need to maintain your own intermediate sample + buffer, since pushing individual sample values isn't very efficient. + The following example is from the MOD player sample in + sokol-samples (https://github.com/floooh/sokol-samples): + + const int num_frames = saudio_expect(); + if (num_frames > 0) { + const int num_samples = num_frames * saudio_channels(); + read_samples(flt_buf, num_samples); + saudio_push(flt_buf, num_frames); + } + + Another option is to ignore saudio_expect(), and just push samples as they + are generated in small batches. In this case you *need* to generate the + samples at the right sample rate: + + The following example is taken from the Tiny Emulators project + (https://github.com/floooh/chips-test), this is for mono playback, + so (num_samples == num_frames): + + // tick the sound generator + if (ay38910_tick(&sys->psg)) { + // new sample is ready + sys->sample_buffer[sys->sample_pos++] = sys->psg.sample; + if (sys->sample_pos == sys->num_samples) { + // new sample packet is ready + saudio_push(sys->sample_buffer, sys->num_samples); + sys->sample_pos = 0; + } + } + + THE WEBAUDIO BACKEND + ==================== + The WebAudio backend is currently using a ScriptProcessorNode callback to + feed the sample data into WebAudio. ScriptProcessorNode has been + deprecated for a while because it is running from the main thread, with + the default initialization parameters it works 'pretty well' though. + Ultimately Sokol Audio will use Audio Worklets, but this requires a few + more things to fall into place (Audio Worklets implemented everywhere, + SharedArrayBuffers enabled again, and I need to figure out a 'low-cost' + solution in terms of implementation effort, since Audio Worklets are + a lot more complex than ScriptProcessorNode if the audio data needs to come + from the main thread). + + The WebAudio backend is automatically selected when compiling for + emscripten (__EMSCRIPTEN__ define exists). + + https://developers.google.com/web/updates/2017/12/audio-worklet + https://developers.google.com/web/updates/2018/06/audio-worklet-design-pattern + + "Blob URLs": https://www.html5rocks.com/en/tutorials/workers/basics/ + + THE COREAUDIO BACKEND + ===================== + The CoreAudio backend is selected on macOS and iOS (__APPLE__ is defined). + Since the CoreAudio API is implemented in C (not Objective-C) on macOS the + implementation part of Sokol Audio can be included into a C source file. + + However on iOS, Sokol Audio must be compiled as Objective-C due to it's + reliance on the AVAudioSession object. The iOS code path support both + being compiled with or without ARC (Automatic Reference Counting). + + For thread synchronisation, the CoreAudio backend will use the + pthread_mutex_* functions. + + The incoming floating point samples will be directly forwarded to + CoreAudio without further conversion. + + macOS and iOS applications that use Sokol Audio need to link with + the AudioToolbox framework. + + THE WASAPI BACKEND + ================== + The WASAPI backend is automatically selected when compiling on Windows + (_WIN32 is defined). + + For thread synchronisation a Win32 critical section is used. + + WASAPI may use a different size for its own streaming buffer then requested, + so the base latency may be slightly bigger. The current backend implementation + converts the incoming floating point sample values to signed 16-bit + integers. + + The required Windows system DLLs are linked with #pragma comment(lib, ...), + so you shouldn't need to add additional linker libs in the build process + (otherwise this is a bug which should be fixed in sokol_audio.h). + + THE ALSA BACKEND + ================ + The ALSA backend is automatically selected when compiling on Linux + ('linux' is defined). + + For thread synchronisation, the pthread_mutex_* functions are used. + + Samples are directly forwarded to ALSA in 32-bit float format, no + further conversion is taking place. + + You need to link with the 'asound' library, and the + header must be present (usually both are installed with some sort + of ALSA development package). + + LICENSE + ======= + + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

These zero-init values + will be replaced with their concrete values in the returned desc + struct. + + ON INITIALIZATION: + ================== + When calling sg_setup(), a pointer to an sg_desc struct must be provided + which contains initialization options. These options provide two types + of information to sokol-gfx: + + (1) upper bounds and limits needed to allocate various internal + data structures: + - the max number of resources of each type that can + be alive at the same time, this is used for allocating + internal pools + - the max overall size of uniform data that can be + updated per frame, including a worst-case alignment + per uniform update (this worst-case alignment is 256 bytes) + - the max size of all dynamic resource updates (sg_update_buffer, + sg_append_buffer and sg_update_image) per frame + - the max number of entries in the texture sampler cache + (how many unique texture sampler can exist at the same time) + Not all of those limit values are used by all backends, but it is + good practice to provide them none-the-less. + + (2) 3D-API "context information" (sometimes also called "bindings"): + sokol_gfx.h doesn't create or initialize 3D API objects which are + closely related to the presentation layer (this includes the "rendering + device", the swapchain, and any objects which depend on the + swapchain). These API objects (or callback functions to obtain + them, if those objects might change between frames), must + be provided in a nested sg_context_desc struct inside the + sg_desc struct. If sokol_gfx.h is used together with + sokol_app.h, have a look at the sokol_glue.h header which provides + a convenience function to get a sg_context_desc struct filled out + with context information provided by sokol_app.h + + See the documention block of the sg_desc struct below for more information. + + BACKEND-SPECIFIC TOPICS: + ======================== + --- the GL backends need to know about the internal structure of uniform + blocks, and the texture sampler-name and -type: + + typedef struct { + float mvp[16]; // model-view-projection matrix + float offset0[2]; // some 2D vectors + float offset1[2]; + float offset2[2]; + } params_t; + + // uniform block structure and texture image definition in sg_shader_desc: + sg_shader_desc desc = { + // uniform block description (size and internal structure) + .vs.uniform_blocks[0] = { + .size = sizeof(params_t), + .uniforms = { + [0] = { .name="mvp", .type=SG_UNIFORMTYPE_MAT4 }, + [1] = { .name="offset0", .type=SG_UNIFORMTYPE_VEC2 }, + ... + } + }, + // one texture on the fragment-shader-stage, GLES2/WebGL needs name and image type + .fs.images[0] = { .name="tex", .type=SG_IMAGETYPE_ARRAY } + ... + }; + + --- the Metal and D3D11 backends only need to know the size of uniform blocks, + not their internal member structure, and they only need to know + the type of a texture sampler, not its name: + + sg_shader_desc desc = { + .vs.uniform_blocks[0].size = sizeof(params_t), + .fs.images[0].type = SG_IMAGETYPE_ARRAY, + ... + }; + + --- when creating a shader object, GLES2/WebGL need to know the vertex + attribute names as used in the vertex shader: + + sg_shader_desc desc = { + .attrs = { + [0] = { .name="position" }, + [1] = { .name="color1" } + } + }; + + The vertex attribute names provided when creating a shader will be + used later in sg_create_pipeline() for matching the vertex layout + to vertex shader inputs. + + --- on D3D11 you need to provide a semantic name and semantic index in the + shader description struct instead (see the D3D11 documentation on + D3D11_INPUT_ELEMENT_DESC for details): + + sg_shader_desc desc = { + .attrs = { + [0] = { .sem_name="POSITION", .sem_index=0 } + [1] = { .sem_name="COLOR", .sem_index=1 } + } + }; + + The provided semantic information will be used later in sg_create_pipeline() + to match the vertex layout to vertex shader inputs. + + --- on D3D11, and when passing HLSL source code (instead of byte code) to shader + creation, you can optionally define the shader model targets on the vertex + stage: + + sg_shader_Desc desc = { + .vs = { + ... + .d3d11_target = "vs_5_0" + }, + .fs = { + ... + .d3d11_target = "ps_5_0" + } + }; + + The default targets are "ps_4_0" and "fs_4_0". Note that those target names + are only used when compiling shaders from source. They are ignored when + creating a shader from bytecode. + + --- on Metal, GL 3.3 or GLES3/WebGL2, you don't need to provide an attribute + name or semantic name, since vertex attributes can be bound by their slot index + (this is mandatory in Metal, and optional in GL): + + sg_pipeline_desc desc = { + .layout = { + .attrs = { + [0] = { .format=SG_VERTEXFORMAT_FLOAT3 }, + [1] = { .format=SG_VERTEXFORMAT_FLOAT4 } + } + } + }; + + WORKING WITH CONTEXTS + ===================== + sokol-gfx allows to switch between different rendering contexts and + associate resource objects with contexts. This is useful to + create GL applications that render into multiple windows. + + A rendering context keeps track of all resources created while + the context is active. When the context is destroyed, all resources + "belonging to the context" are destroyed as well. + + A default context will be created and activated implicitly in + sg_setup(), and destroyed in sg_shutdown(). So for a typical application + which *doesn't* use multiple contexts, nothing changes, and calling + the context functions isn't necessary. + + Three functions have been added to work with contexts: + + --- sg_context sg_setup_context(): + This must be called once after a GL context has been created and + made active. + + --- void sg_activate_context(sg_context ctx) + This must be called after making a different GL context active. + Apart from 3D-API-specific actions, the call to sg_activate_context() + will internally call sg_reset_state_cache(). + + --- void sg_discard_context(sg_context ctx) + This must be called right before a GL context is destroyed and + will destroy all resources associated with the context (that + have been created while the context was active) The GL context must be + active at the time sg_discard_context(sg_context ctx) is called. + + Also note that resources (buffers, images, shaders and pipelines) must + only be used or destroyed while the same GL context is active that + was also active while the resource was created (an exception is + resource sharing on GL, such resources can be used while + another context is active, but must still be destroyed under + the same context that was active during creation). + + For more information, check out the multiwindow-glfw sample: + + https://github.com/floooh/sokol-samples/blob/master/glfw/multiwindow-glfw.c + + TRACE HOOKS: + ============ + sokol_gfx.h optionally allows to install "trace hook" callbacks for + each public API functions. When a public API function is called, and + a trace hook callback has been installed for this function, the + callback will be invoked with the parameters and result of the function. + This is useful for things like debugging- and profiling-tools, or + keeping track of resource creation and destruction. + + To use the trace hook feature: + + --- Define SOKOL_TRACE_HOOKS before including the implementation. + + --- Setup an sg_trace_hooks structure with your callback function + pointers (keep all function pointers you're not interested + in zero-initialized), optionally set the user_data member + in the sg_trace_hooks struct. + + --- Install the trace hooks by calling sg_install_trace_hooks(), + the return value of this function is another sg_trace_hooks + struct which contains the previously set of trace hooks. + You should keep this struct around, and call those previous + functions pointers from your own trace callbacks for proper + chaining. + + As an example of how trace hooks are used, have a look at the + imgui/sokol_gfx_imgui.h header which implements a realtime + debugging UI for sokol_gfx.h on top of Dear ImGui. + + A NOTE ON PORTABLE PACKED VERTEX FORMATS: + ========================================= + There are two things to consider when using packed + vertex formats like UBYTE4, SHORT2, etc which need to work + across all backends: + + - D3D11 can only convert *normalized* vertex formats to + floating point during vertex fetch, normalized formats + have a trailing 'N', and are "normalized" to a range + -1.0..+1.0 (for the signed formats) or 0.0..1.0 (for the + unsigned formats): + + - SG_VERTEXFORMAT_BYTE4N + - SG_VERTEXFORMAT_UBYTE4N + - SG_VERTEXFORMAT_SHORT2N + - SG_VERTEXFORMAT_USHORT2N + - SG_VERTEXFORMAT_SHORT4N + - SG_VERTEXFORMAT_USHORT4N + + D3D11 will not convert *non-normalized* vertex formats to floating point + vertex shader inputs, those can only be uses with the *ivecn* vertex shader + input types when D3D11 is used as backend (GL and Metal can use both formats) + + - SG_VERTEXFORMAT_BYTE4, + - SG_VERTEXFORMAT_UBYTE4 + - SG_VERTEXFORMAT_SHORT2 + - SG_VERTEXFORMAT_SHORT4 + + - WebGL/GLES2 cannot use integer vertex shader inputs (int or ivecn) + + - SG_VERTEXFORMAT_UINT10_N2 is not supported on WebGL/GLES2 + + So for a vertex input layout which works on all platforms, only use the following + vertex formats, and if needed "expand" the normalized vertex shader + inputs in the vertex shader by multiplying with 127.0, 255.0, 32767.0 or + 65535.0: + + - SG_VERTEXFORMAT_FLOAT, + - SG_VERTEXFORMAT_FLOAT2, + - SG_VERTEXFORMAT_FLOAT3, + - SG_VERTEXFORMAT_FLOAT4, + - SG_VERTEXFORMAT_BYTE4N, + - SG_VERTEXFORMAT_UBYTE4N, + - SG_VERTEXFORMAT_SHORT2N, + - SG_VERTEXFORMAT_USHORT2N + - SG_VERTEXFORMAT_SHORT4N, + - SG_VERTEXFORMAT_USHORT4N + + TODO: + ==== + - talk about asynchronous resource creation + + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

The pipeline object at + the top of the pipeline stack defines the active set of render states + - All angles are in radians, not degrees (note the sgl_rad() and + sgl_deg() conversion functions) + - No enable/disable state for scissor test, this is always enabled + + STEP BY STEP: + ============= + --- To initialize sokol-gl, call: + + sgl_setup(const sgl_desc_t* desc) + + NOTE that sgl_setup() must be called *after* initializing sokol-gfx + (via sg_setup).

This is + the same as OpenGL's default, but different from sokol-gfx. + + --- Optionally create pipeline-state-objects if you need render state + that differs from sokol-gl's default state: + + sgl_pipeline pip = sgl_make_pipeline(const sg_pipeline_desc* desc) + + The similarity with sokol_gfx.h's sg_pipeline type and sg_make_pipeline() + function is intended. sgl_make_pipeline() also takes a standard + sokol-gfx sg_pipeline_desc object to describe the render state, but + without: + - shader + - vertex layout + - color- and depth-pixel-formats + - primitive type (lines, triangles, ...) + - MSAA sample count + Those will be filled in by sgl_make_pipeline(). Note that each + call to sgl_make_pipeline() needs to create several sokol-gfx + pipeline objects (one for each primitive type). + + --- if you need to destroy sgl_pipeline objects before sgl_shutdown(): + + sgl_destroy_pipeline(sgl_pipeline pip) + + --- After sgl_setup() you can call any of the sokol-gl functions anywhere + in a frame, *except* sgl_draw(). The 'vanilla' functions + will only change internal sokol-gl state, and not call any sokol-gfx + functions. + + --- Unlike OpenGL, sokol-gl has a function to reset internal state to + a known default.

The pixel data consists of *y scanlines of *x pixels, +// with each pixel consisting of N interleaved 8-bit components; the first +// pixel pointed to is top-left-most in the image. There is no padding between +// image scanlines or between pixels, regardless of format. The number of +// components N is 'desired_channels' if desired_channels is non-zero, or +// *channels_in_file otherwise. If desired_channels is non-zero, +// *channels_in_file has the number of components that _would_ have been +// output otherwise. E.g. if you set desired_channels to 4, you will always +// get RGBA output, but you can check *channels_in_file to see if it's trivially +// opaque because e.g. there were only 3 channels in the source image. +// +// An output image with N components has the following components interleaved +// in this order in each pixel: +// +// N=#comp components +// 1 grey +// 2 grey, alpha +// 3 red, green, blue +// 4 red, green, blue, alpha +// +// If image loading fails for any reason, the return value will be NULL, +// and *x, *y, *channels_in_file will be unchanged. The function +// stbi_failure_reason() can be queried for an extremely brief, end-user +// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS +// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly +// more user-friendly ones. +// +// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. +// +// =========================================================================== +// +// UNICODE: +// +// If compiling for Windows and you wish to use Unicode filenames, compile +// with +// #define STBI_WINDOWS_UTF8 +// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert +// Windows wchar_t filenames to utf8. +// +// =========================================================================== +// +// Philosophy +// +// stb libraries are designed with the following priorities: +// +// 1. easy to use +// 2. easy to maintain +// 3. good performance +// +// Sometimes I let "good performance" creep up in priority over "easy to maintain", +// and for best performance I may provide less-easy-to-use APIs that give higher +// performance, in addition to the easy-to-use ones. Nevertheless, it's important +// to keep in mind that from the standpoint of you, a client of this library, +// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. +// +// Some secondary priorities arise directly from the first two, some of which +// provide more explicit reasons why performance can't be emphasized. +// +// - Portable ("ease of use") +// - Small source code footprint ("easy to maintain") +// - No dependencies ("ease of use") +// +// =========================================================================== +// +// I/O callbacks +// +// I/O callbacks allow you to read from arbitrary sources, like packaged +// files or some other source. Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image supports loading HDR images in general, and currently the Radiance +// .HDR file format specifically. You can still load any file through the existing +// interface; if you attempt to load an HDR file, it will be automatically remapped +// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// By default we convert iphone-formatted PNGs back to RGB, even though +// they are internally encoded differently. You can disable this conversion +// by calling stbi_convert_iphone_png_to_rgb(0), in which case +// you will always just get the native iphone "format" through (which +// is BGR stored in RGB). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// +// =========================================================================== +// +// ADDITIONAL CONFIGURATION +// +// - You can suppress implementation of any of the decoders to reduce +// your code footprint by #defining one or more of the following +// symbols before creating the implementation. +// +// STBI_NO_JPEG +// STBI_NO_PNG +// STBI_NO_BMP +// STBI_NO_PSD +// STBI_NO_TGA +// STBI_NO_GIF +// STBI_NO_HDR +// STBI_NO_PIC +// STBI_NO_PNM (.ppm and .pgm) +// +// - You can request *only* certain decoders and suppress all other ones +// (this will be more forward-compatible, as addition of new decoders +// doesn't require you to disable them explicitly): +// +// STBI_ONLY_JPEG +// STBI_ONLY_PNG +// STBI_ONLY_BMP +// STBI_ONLY_PSD +// STBI_ONLY_TGA +// STBI_ONLY_GIF +// STBI_ONLY_HDR +// STBI_ONLY_PIC +// STBI_ONLY_PNM (.ppm and .pgm) +// +// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still +// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB +// +// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater +// than that size (in either width or height) without further processing. +// This is to let programs in the wild set an upper bound to prevent +// denial-of-service attacks on untrusted data, as one could generate a +// valid image of gigantic dimensions and force stb_image to allocate a +// huge block of memory and spend disproportionate time decoding it.

Hopefully this fix won't + cause any issues on weird zip archives, because it assumes the low 16-bits of + zip external attributes are DOS attributes (which I believe they always are + in practice). + - Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the + internal attributes, just the filename and external attributes + - mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed + - Added cmake support for Linux builds which builds all the examples, + tested with clang v3.3 and gcc v4.6. + - Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti + - Merged MZ_FORCEINLINE fix from hdeanclark + - Fix include before config #ifdef, thanks emil.brink + - Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping + (super useful for OpenGL apps), and explicit control over the compression + level (so you can set it to 1 for real-time compression). + - Merged in some compiler fixes from paulharris's github repro. + - Retested this build under Windows (VS 2010, including static analysis), + tcc 0.9.26, gcc v4.6 and clang v3.3. + - Added example6.c, which dumps an image of the mandelbrot set to a PNG + file. + - Modified example2 to help test the + MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more. + - In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix + possible src file fclose() leak if alignment bytes+local header file write + faiiled + - In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader(): Was pushing the + wrong central dir header offset, appears harmless in this release, but it + became a problem in the zip64 branch 5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 + compiler fixes: added MZ_FORCEINLINE, #include (thanks fermtect). + 5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix + mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit. + - Temporarily/locally slammed in "typedef unsigned long mz_ulong" and + re-ran a randomized regression test on ~500k files. + - Eliminated a bunch of warnings when compiling with GCC 32-bit/64. + - Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze + (static analysis) option and fixed all warnings (except for the silly "Use of + the comma-operator in a tested expression.." analysis warning, which I + purposely use to work around a MSVC compiler warning). + - Created 32-bit and 64-bit Codeblocks projects/workspace. Built and + tested Linux executables. The codeblocks workspace is compatible with + Linux+Win32/x64. + - Added miniz_tester solution/project, which is a useful little app + derived from LZHAM's tester app that I use as part of the regression test. + - Ran miniz.c and tinfl.c through another series of regression testing on + ~500,000 files and archives. + - Modified example5.c so it purposely disables a bunch of high-level + functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the + MINIZ_NO_STDIO bug report.) + - Fix ftell() usage in examples so they exit with an error on files which + are too large (a limitation of the examples, not miniz itself). 4/12/12 v1.12 + - More comments, added low-level example5.c, fixed a couple minor + level_and_flags issues in the archive API's. level_and_flags can now be set + to MZ_DEFAULT_COMPRESSION. Thanks to Bruce Dawson + for the feedback/bug report. 5/28/11 v1.11 - Added statement from + unlicense.org 5/27/11 v1.10 - Substantial compressor optimizations: + - Level 1 is now ~4x faster than before. The L1 compressor's throughput + now varies between 70-110MB/sec. on a + - Core i7 (actual throughput varies depending on the type of data, and x64 + vs. x86). + - Improved baseline L2-L9 compression perf. Also, greatly improved + compression perf. issues on some file types. + - Refactored the compression code for better readability and + maintainability. + - Added level 10 compression level (L10 has slightly better ratio than + level 9, but could have a potentially large drop in throughput on some + files). 5/15/11 v1.09 - Initial stable release. + + * Low-level Deflate/Inflate implementation notes: + + Compression: Use the "tdefl" API's. The compressor supports raw, static, + and dynamic blocks, lazy or greedy parsing, match length filtering, RLE-only, + and Huffman-only streams. It performs and compresses approximately as well as + zlib. + + Decompression: Use the "tinfl" API's. The entire decompressor is + implemented as a single function coroutine: see tinfl_decompress(). It + supports decompression into a 32KB (or larger power of 2) wrapping buffer, or + into a memory block large enough to hold the entire file. + + The low-level tdefl/tinfl API's do not make any use of dynamic memory + allocation. + + * zlib-style API notes: + + miniz.c implements a fairly large subset of zlib. There's enough + functionality present for it to be a drop-in zlib replacement in many apps: + The z_stream struct, optional memory allocation callbacks + deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound + inflateInit/inflateInit2/inflate/inflateEnd + compress, compress2, compressBound, uncompress + CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly + routines. Supports raw deflate streams or standard zlib streams with adler-32 + checking. + + Limitations: + The callback API's are not implemented yet. No support for gzip headers or + zlib static dictionaries. I've tried to closely emulate zlib's various + flavors of stream flushing and return status codes, but there are no + guarantees that miniz.c pulls this off perfectly. + + * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, + originally written by Alex Evans. Supports 1-4 bytes/pixel images. + + * ZIP archive API notes: + + The ZIP archive API's where designed with simplicity and efficiency in + mind, with just enough abstraction to get the job done with minimal fuss. + There are simple API's to retrieve file information, read files from existing + archives, create new archives, append new files to existing archives, or + clone archive data from one archive to another. It supports archives located + in memory or the heap, on disk (using stdio.h), or you can specify custom + file read/write callbacks. + + - Archive reading: Just call this function to read a single file from a + disk archive: + + void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const + char *pArchive_name, size_t *pSize, mz_uint zip_flags); + + For more complex cases, use the "mz_zip_reader" functions. Upon opening an + archive, the entire central directory is located and read as-is into memory, + and subsequent file access only occurs when reading individual files. + + - Archives file scanning: The simple way is to use this function to scan a + loaded archive for a specific file: + + int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, + const char *pComment, mz_uint flags); + + The locate operation can optionally check file comments too, which (as one + example) can be used to identify multiple versions of the same file in an + archive. This function uses a simple linear search through the central + directory, so it's not very fast. + + Alternately, you can iterate through all the files in an archive (using + mz_zip_reader_get_num_files()) and retrieve detailed info on each file by + calling mz_zip_reader_file_stat(). + + - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer + immediately writes compressed file data to disk and builds an exact image of + the central directory in memory. The central directory image is written all + at once at the end of the archive file when the archive is finalized. + + The archive writer can optionally align each file's local header and file + data to any power of 2 alignment, which can be useful when the archive will + be read from optical media. Also, the writer supports placing arbitrary data + blobs at the very beginning of ZIP archives. Archives written using either + feature are still readable by any ZIP tool. + + - Archive appending: The simple way to add a single file to an archive is + to call this function: + + mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, + const char *pArchive_name, const void *pBuf, size_t buf_size, const void + *pComment, mz_uint16 comment_size, mz_uint level_and_flags); + + The archive will be created if it doesn't already exist, otherwise it'll be + appended to. Note the appending is done in-place and is not an atomic + operation, so if something goes wrong during the operation it's possible the + archive could be left without a central directory (although the local file + headers and file data will be fine, so the archive will be recoverable). + + For more complex archive modification scenarios: + 1. The safest way is to use a mz_zip_reader to read the existing archive, + cloning only those bits you want to preserve into a new archive using using + the mz_zip_writer_add_from_zip_reader() function (which compiles the + compressed file data as-is). When you're done, delete the old archive and + rename the newly written archive, and you're done. This is safe but requires + a bunch of temporary disk space or heap memory. + + 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using + mz_zip_writer_init_from_reader(), append new files as needed, then finalize + the archive which will write an updated central directory to the original + archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() + does.) There's a possibility that the archive's central directory could be + lost with this method if anything goes wrong, though. + + - ZIP archive support limitations: + No zip64 or spanning support.

If you have experience +with an MVC web framework, you can think of it as a controller. (Vweb is +not an MVC framework however.) It embeds the vweb Context object, that's why we get access +to methods like `.text()`. + + +As you can see, there are no routing rules. The `index()` action handles the `/` request by default. +Vweb often uses convention over configuration and adding a new action requires +no routing rules either: + +```v oksyntax +// blog.v +import vweb +import time + +fn (mut app App) time() vweb.Result { + return app.text(time.now().format()) +} +``` + + + + +>You have to rebuild and restart the website every time you change the code. +In the future, Vweb will detect changes and recompile the website in the background +while it's running. + +The `.text(string)` method returns a plain text document with the provided +text, which isn't frequently used in websites. + + +### HTML View + +Let's return an HTML view instead. Create `index.html` in the same directory: + +```html + + + V Blog + + + @message +
        + + + +``` + +and update our `index()` action so that it returns the HTML view we just created: + +```v ignore +// blog.v +pub fn (mut app App) index() vweb.Result { + message := 'Hello, world from Vweb!' + return $vweb.html() +} +``` + + + +Good, now we have an actual HTML page. + +The V template language is similar to C#'s Razor: `@message` prints the value +of `message`. + +You may notice something unusual: the `message` variable created in the `index()` +action is automatically available in the view. + +It's another feature of Vweb to reduce the boilerplate in your web apps. +No need to create view models just to pass data, or use an unsafe and untyped +alternative, like C#'s `ViewBag["message"]`. + +Making all action variables available in the view may seem crazy, +but V is a language with pure functions by default, and you won't be able +to modify any data from a view. `@foo.bar()` will only work if the `bar()` method +doesn't modify `foo`. + +The HTML template is compiled to V during the compilation of the website, +that's done by the `$vweb.html()` line. +(`$` always means compile time actions in V.) offering the following benefits: + +- Great performance, since the templates don't need to be compiled +on every request, like in almost every major web framework. + +- Easier deployment, since all your HTML templates are compiled +into a single binary file together with the web application itself. + +- All errors in the templates are guaranteed to be caught during compilation. + + +### Fetching data with V ORM + +Now let's display some articles! + +We'll be using V's builtin ORM and a SQLite database. +(V ORM will also support MySQL, Postgre, and SQL Server soon.) + + +Add a SQLite handle to `App`: + +```v oksyntax +// blog.v +import sqlite +import vweb + +struct App { + vweb.Context +pub mut: + db sqlite.DB +} +``` + + + +Add the `init_server()` method where we'll connect to a database: + +```v oksyntax +// blog.v +pub fn (mut app App) init_server() { + app.db = sqlite.connect(':memory:') or { panic(err) } + sql app.db { + create table Article + } + + first_article := Article{ + title: 'Hello, world!' + text: 'V is great.' + } + + second_article := Article{ + title: 'Second post.' + text: 'Hm... what should I write about?' + } + + sql app.db { + insert first_article into Article + insert second_article into Article + } +} +``` + +Code in the `init_server()` function is run only once during app's startup, so we are going +to have one DB connection for all requests. Modify the main method to call the `init_server()` +function before adding it to the vweb system: + +```v oksyntax +fn main() { + mut app := App{} + app.init_server() + vweb.run(app, 8081) +} +``` + +Because `init_server()` modifies properties of the app struct we now have to make it mutable +with the `mut` keyword. + +Create a new file `article.v`: + + +```v oksyntax +// article.v +module main + +struct Article { + id int [primary; sql: serial] + title string + text string +} + +pub fn (app &App) find_all_articles() []Article { + return sql app.db { + select from Article + } +} +``` + +Notice that the `Article` structure conforms to the same structure and naming as +the database table in the creation SQL statement. Also we need to add ORM decorators +to our primary key to let it know that it is the primary key and it should auto-increment + +Let's fetch the articles in the `index()` action: + +```v ignore +// blog.v +pub fn (app App) index() vweb.Result { + articles := app.find_all_articles() + return $vweb.html() +} +``` + + +Finally, let's update our view: + +```html + + @for article in articles +
        + @article.title
        + @article.text +
        + @end + +``` + +```bash +v run . +``` + + + +That was very simple, wasn't it? + +The built-in V ORM uses a syntax very similar to SQL. The queries are built with V. +For example, if we only wanted to find articles with ids between 100 and 200, we'd do: + +```v oksyntax +// article.v + +return sql app.db { + select from Article where id >= 100 && id <= 200 +} +``` + +Retrieving a single article is very simple: + +```v oksyntax +// article.v +pub fn (app &App) retrieve_article() ?Article { + return sql app.db { + select from Article limit 1 + } +} +``` + +V ORM uses V's optionals for single values, which is very useful, since +bad queries will always be handled by the developer: + +```v ignore +// article.v +article := app.retrieve_article(10) or { + app.text('Article not found') + return +} +``` + + +### Adding new articles + +Create `new.html`: + +```html + + + V Blog + + +
        +
        + + +
        + + +``` + +```v ignore +// article.v +import vweb +['/new_article'; post] +pub fn (mut app App) new_article() vweb.Result { + title := app.form['title'] + text := app.form['text'] + if title == '' || text == '' { + return app.text('Empty text/title') + } + article := Article{ + title: title + text: text + } + println(article) + sql app.db { + insert article into Article + } + return app.redirect('/') +} +``` + +> Untyped `form['key']` is temporary. Very soon Vweb will accept query and form +parameters via function arguments: `new_article(title, text string) {`. + +The decorator on our function tells vweb the path to our endpoint, `/new_article`, +and that it is an HTTP POST type operation. + +We need to update `index.html` to add a link to the "new article" page: + +```html +New article +``` + +Next we need to add the HTML endpoint to our code like we did with `index.html`: + +```v ignore +['/new'] +pub fn (mut app App) new() vweb.Result { + return $vweb.html() +} +``` + +Re-running this code will now allow us to add new posts to our blog endpoint + + +### JSON endpoints + +This tutorial used the traditional server-side rendering. If you prefer +to render everything on the client or need an API, creating JSON endpoints +in V is very simple: + +```v oksyntax +// article.v +import vweb +import json + +['/articles'; get] +pub fn (mut app App) articles() vweb.Result { + articles := app.find_all_articles() + return app.json(json.encode(articles)) +} +``` + + + + +### Persistent data +If one wants to persist data they need to use a file instead of memory SQLite Database. +Replace the `init_server()` function with this instead: + +```v oksyntax +// blog.v +pub fn (mut app App) init_server() { + app.db = sqlite.connect('blog.db') or { panic(err) } + sql app.db { + create table Article + } +} +``` + +As we can see it attempts to open a file in the current directory named `blog.db`. +If the database file doesn't exist it will create it. The second command will +create the table `Article` if none exists already. Now every time the +app is run you will see the articles created from the previous executions + + +To be continued... + +For an example of a more sophisticated web app written in V, check out Vorum: https://github.com/vlang/vorum diff --git a/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/.gitignore b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/.gitignore new file mode 100644 index 0000000..2fdf6da --- /dev/null +++ b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/.gitignore @@ -0,0 +1 @@ +blog.db diff --git a/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/article.v b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/article.v new file mode 100644 index 0000000..f127532 --- /dev/null +++ b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/article.v @@ -0,0 +1,13 @@ +module main + +struct Article { + id int [primary; sql: serial] + title string + text string +} + +pub fn (app &App) find_all_articles() []Article { + return sql app.db { + select from Article + } +} diff --git a/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/blog.sqlite b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/blog.sqlite new file mode 100644 index 0000000..c5956d6 --- /dev/null +++ b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/blog.sqlite @@ -0,0 +1,17 @@ +drop table if exists Article; + +create table Article ( + id integer primary key, + title text default "", + text text default "" +); + +insert into Article (title, text) values ( + "Hello, world!", + "V is great." +); + +insert into Article (title, text) values ( + "Second post.", + "Hm... what should I write about?" +); diff --git a/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/blog.v b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/blog.v new file mode 100644 index 0000000..823567c --- /dev/null +++ b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/blog.v @@ -0,0 +1,83 @@ +module main + +import vweb +import time +import sqlite +import json + +struct App { + vweb.Context +pub mut: + db sqlite.DB [server_var] + user_id string +} + +fn main() { + mut app := App{} + app.init_server() + vweb.run(app, 8081) +} + +/* +pub fn (mut app App) index_text() vweb.Result { + app.vweb.text('Hello, world from vweb!') + return vweb.Result{} +} + +pub fn (app &App) index_html() vweb.Result { + message := 'Hello, world from Vweb!' + return $vweb.html() +} +*/ +['/index'] +pub fn (app &App) index() vweb.Result { + articles := app.find_all_articles() + return $vweb.html() +} + +pub fn (mut app App) init_server() { + app.db = sqlite.connect('blog.db') or { panic(err) } + sql app.db { + create table Article + } +} + +pub fn (mut app App) before_request() { + app.user_id = app.get_cookie('id') or { '0' } +} + +['/new'] +pub fn (mut app App) new() vweb.Result { + return $vweb.html() +} + +['/new_article'; post] +pub fn (mut app App) new_article() vweb.Result { + title := app.form['title'] + text := app.form['text'] + if title == '' || text == '' { + return app.text('Empty text/title') + } + article := Article{ + title: title + text: text + } + println('posting article') + println(article) + sql app.db { + insert article into Article + } + + return app.redirect('/') +} + +['/articles'; get] +pub fn (mut app App) articles() vweb.Result { + articles := app.find_all_articles() + json_result := json.encode(articles) + return app.json(json_result) +} + +fn (mut app App) time() { + app.text(time.now().format()) +} diff --git a/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/index.html b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/index.html new file mode 100644 index 0000000..399b267 --- /dev/null +++ b/v_windows/v/old/tutorials/building_a_simple_web_blog_with_vweb/code/blog/index.html @@ -0,0 +1,16 @@ + +

It has several traits that +in combination makes it very fast and memory efficient. Here is a short expl- +anation of each trait. After reading this you should have a basic understand- +ing of how it functions: + +1. Hash-function: Wyhash. Wyhash is the fastest hash-function for short keys +passing SMHasher, so it was an obvious choice. + +2. Open addressing: Robin Hood Hashing. With this method, a hash-collision is +resolved by probing. As opposed to linear probing, Robin Hood hashing has a +simple but clever twist: As new keys are inserted, old keys are shifted arou- +nd in a way such that all keys stay reasonably close to the slot they origin- +ally hash to. A new key may displace a key already inserted if its probe cou- +nt is larger than that of the key at the current position. + +3. Memory layout: key-value pairs are stored in a `DenseArray`. This is a dy- +namic array with a very low volume of unused memory, at the cost of more rea- +llocations when inserting elements. It also preserves the order of the key-v- +alues. This array is named `key_values`. Instead of probing a new key-value, +this map probes two 32-bit numbers collectively. The first number has its 8 +most significant bits reserved for the probe-count and the remaining 24 bits +are cached bits from the hash which are utilized for faster re-hashing. This +number is often referred to as `meta`. The other 32-bit number is the index +at which the key-value was pushed to in `key_values`. Both of these numbers +are stored in a sparse array `metas`. The `meta`s and `kv_index`s are stored +at even and odd indices, respectively: + +metas = [meta, kv_index, 0, 0, meta, kv_index, 0, 0, meta, kv_index, ...] +key_values = [kv, kv, kv, ...] + +4. The size of metas is a power of two. This enables the use of bitwise AND +to convert the 64-bit hash to a bucket/index that doesn't overflow metas. If +the size is power of two you can use "hash & (SIZE - 1)" instead of "hash % +SIZE". Modulo is extremely expensive so using '&' is a big performance impro- +vement. The general concern with this approach is that you only make use of +the lower bits of the hash which can cause more collisions. This is solved by +using a well-dispersed hash-function. + +5. The hashmap keeps track of the highest probe_count. The trick is to alloc- +ate `extra_metas` > max(probe_count), so you never have to do any bounds-che- +cking since the extra meta memory ensures that a meta will never go beyond +the last index. + +6. Cached rehashing. When the `load_factor` of the map exceeds the `max_load_ +factor` the size of metas is doubled and all the key-values are "rehashed" to +find the index for their meta's in the new array. Instead of rehashing compl- +etely, it simply uses the cached-hashbits stored in the meta, resulting in +much faster rehashing. +*/ +const ( + // Number of bits from the hash stored for each entry + hashbits = 24 + // Number of bits from the hash stored for rehashing + max_cached_hashbits = 16 + // Initial log-number of buckets in the hashtable + init_log_capicity = 5 + // Initial number of buckets in the hashtable + init_capicity = 1 << init_log_capicity + // Maximum load-factor (len / capacity) + max_load_factor = 0.8 + // Initial highest even index in metas + init_even_index = init_capicity -

These functions make use of the global RNG. + +**Note:** The global PRNG is not thread safe. It is recommended to use separate generators for +separate threads in multi-threaded applications.

The matching stops at the end of the string, *not* at newline characters. + +2. The basic atomic elements of this regex engine are the tokens. +In a query string a simple character is a token. + + +## Differences with PCRE: + +NB: We must point out that the **V-Regex module is not PCRE compliant** and thus +some behaviour will be different. This difference is due to the V philosophy, +to have one way and keep it simple. + +The main differences can be summarized in the following points: + +- The basic element **is the token not the sequence of symbols**, and the most +simple token, is a single character. + +- `|` **the OR operator acts on tokens,** for example `abc|ebc` is not +`abc` OR `ebc`. Instead it is evaluated like `ab`, followed by `c OR e`, +followed by `bc`, because the **token is the base element**, +not the sequence of symbols. + +- The **match operation stops at the end of the string**. It does *NOT* stop +at new line characters. + + +## Tokens + +The tokens are the atomic units, used by this regex engine. +They can be one of the following: + + +### Simple char + +This token is a simple single character like `a` or `b` etc. + + +### Match positional delimiters + +`^` Matches the start of the string. + +`$` Matches the end of the string. + + +### Char class (cc) + +The character classes match all the chars specified inside. Use square +brackets `[ ]` to enclose them. + +The sequence of the chars in the character class, is evaluated with an OR op. + +For example, the cc `[abc]`, matches any character, that is `a` or `b` or `c`, +but it doesn't match `C` or `z`. + +Inside a cc, it is possible to specify a "range" of characters, for example +`[ad-h]` is equivalent to writing `[adefgh]`. + +A cc can have different ranges at the same time, for example `[a-zA-z0-9]` +matches all the latin lowercase, uppercase and numeric characters. + +It is possible to negate the meaning of a cc, using the caret char at the +start of the cc like this: `[^abc]` . That matches every char that is NOT +`a` or `b` or `c`. + +A cc can contain meta-chars like: `[a-z\d]`, that match all the lowercase +latin chars `a-z` and all the digits `\d`. + +It is possible to mix all the properties of the char class together. + +NB: In order to match the `-` (minus) char, it must be preceded by + a backslash in the cc, for example `[\-_\d\a]` will match: + `-` minus, + `_` underscore, + `\d` numeric chars, + `\a` lower case chars. + +### Meta-chars + +A meta-char is specified by a backslash, before a character. +For example `\w` is the meta-char `w`. + +A meta-char can match different types of characters. + +* `\w` matches an alphanumeric char `[a-zA-Z0-9_]` +* `\W` matches a non alphanumeric char +* `\d` matches a digit `[0-9]` +* `\D` matches a non digit +* `\s` matches a space char, one of `[' ','\t','\n','\r','\v','\f']` +* `\S` matches a non space char +* `\a` matches only a lowercase char `[a-z]` +* `\A` matches only an uppercase char `[A-Z]` + +### Quantifier + +Each token can have a quantifier, that specifies how many times the character +must be matched. + +#### **Short quantifiers** + +- `?` matches 0 or 1 time, `a?b` matches both `ab` or `b` +- `+` matches *at least* 1 time, for example, `a+` matches both `aaa` or `a` +- `*` matches 0 or more times, for example, `a*b` matches `aaab`, `ab` or `b` + +#### **Long quantifiers** + +- `{x}` matches exactly x times, `a{2}` matches `aa`, but not `aaa` or `a` +- `{min,}` matches at least min times, `a{2,}` matches `aaa` or `aa`, not `a` +- `{,max}` matches at least 0 times and at maximum max times, + for example, `a{,2}` matches `a` and `aa`, but doesn't match `aaa` +- `{min,max}` matches from min times, to max times, for example + `a{2,3}` matches `aa` and `aaa`, but doesn't match `a` or `aaaa` + +A long quantifier, may have a `greedy off` flag, that is the `?` +character after the brackets. `{2,4}?` means to match the minimum +number of possible tokens, in this case 2. + +### Dot char + +The dot is a particular meta-char, that matches "any char". + +It is simpler to explain it with an example: + +Suppose you have `abccc ddeef` as a source string, that you want to parse +with a regex. The following table show the query strings and the result of +parsing source string. + ++--------------+-------------+ +| query string | result | +|--------------|-------------| +| `.*c` | `abc` | +| `.*dd` | `abcc dd` | +| `ab.*e` | `abccc dde` | +| `ab.{3} .*e` | `abccc dde` | ++--------------+-------------+ + +The dot matches any character, until the next token match is satisfied. + +### OR token + +The token `|`, means a logic OR operation between two consecutive tokens, +i.e. `a|b` matches a character that is `a` or `b`. + +The OR token can work in a "chained way": `a|(b)|cd ` means test first `a`, +if the char is not `a`, then test the group `(b)`, and if the group doesn't +match too, finally test the token `c`. + +NB: ** unlike in PCRE, the OR operation works at token level!** +It doesn't work at concatenation level! + +That also means, that a query string like `abc|bde` is not equal to +`(abc)|(bde)`, but instead to `ab(c|b)de. +The OR operation works only for `c|b`, not at char concatenation level. + +### Groups + +Groups are a method to create complex patterns with repetitions of blocks +of tokens. The groups are delimited by round brackets `( )`. Groups can be +nested. Like all other tokens, groups can have a quantifier too. + +`c(pa)+z` match `cpapaz` or `cpaz` or `cpapapaz` . + +`(c(pa)+z ?)+` matches `cpaz cpapaz cpapapaz` or `cpapaz` + +Lets analyze this last case, first we have the group `#0`, that is the most +outer round brackets `(...)+`. This group has a quantifier `+`, that say to +match its content *at least one time*. + +Then we have a simple char token `c`, and a second group `#1`: `(pa)+`. +This group also tries to match the sequence `pa`, *at least one time*, +as specified by the `+` quantifier. + +Then, we have another simple token `z` and another simple token ` ?`, +i.e. the space char (ascii code 32) followed by the `?` quantifier, +which means that the preceding space should be matched 0 or 1 time. + +This explains why the `(c(pa)+z ?)+` query string, +can match `cpaz cpapaz cpapapaz` . + +In this implementation the groups are "capture groups". This means that the +last temporal result for each group, can be retrieved from the `RE` struct. + +The "capture groups" are stored as indexes in the field `groups`, +that is an `[]int` inside the `RE` struct. + +**example:** + +```v oksyntax +text := 'cpaz cpapaz cpapapaz' +query := r'(c(pa)+z ?)+' +mut re := regex.regex_opt(query) or { panic(err) } +println(re.get_query()) +// #0(c#1(pa)+z ?)+ +// #0 and #1 are the ids of the groups, are shown if re.debug is 1 or 2 +start, end := re.match_string(text) +// [start=0, end=20] match => [cpaz cpapaz cpapapaz] +mut gi := 0 +for gi < re.groups.len { + if re.groups[gi] >= 0 { + println('${gi / 2} :[${text[re.groups[gi]..re.groups[gi + 1]]}]') + } + gi += 2 +} +// groups captured +// 0 :[cpapapaz] +// 1 :[pa] +``` + +**note:** *to show the `group id number` in the result of the `get_query()`* +*the flag `debug` of the RE object must be `1` or `2`* + +In order to simplify the use of the captured groups, it possible to use the +utility function: `get_group_list`. + +This function return a list of groups using this support struct: + +```v oksyntax +pub struct Re_group { +pub: + start int = -1 + end int = -1 +} +``` + +Here an example of use: + +```v oksyntax +/* +This simple function converts an HTML RGB value with 3 or 6 hex digits to +an u32 value, this function is not optimized and it is only for didatical +purpose.

To achieve this task, we can use the continuous +group saving, by enabling the right flag: `re.group_csave_flag = true`. + +The `.group_csave` array will be filled then, following this logic: + +`re.group_csave[0]` - number of total saved records +`re.group_csave[1+n*3]` - id of the saved group +`re.group_csave[1+n*3]` - start index in the source string of the saved group +`re.group_csave[1+n*3]` - end index in the source string of the saved group + +The regex will save groups, until it finishes, or finds that the array has no +more space. If the space ends, no error is raised, and further records will +not be saved. + +```v ignore +import regex +fn main(){ + txt := "http://www.ciao.mondo/hello/pippo12_/pera.html" + query :=

question mark `?` PCRE syntax for groups. + +`(?:abcd)` **non capturing group**: the content of the group will not be saved. + +`(?Pabcdef)` **named group:** the group content is saved and labeled +as `mygroup`. + +The label of the groups is saved in the `group_map` of the `RE` struct, +that is a map from `string` to `int`, where the value is the index in +`group_csave` list of indexes. + +Here is an example for how to use them: +```v ignore +import regex +fn main(){ + txt := "http://www.ciao.mondo/hello/pippo12_/pera.html" + query := r"(?Phttps?)|(?Pftps?)://(?P[\w_]+.)+" + + mut re := regex.regex_opt(query) or { panic(err) } + //println(re.get_code()) // uncomment to see the print of the regex execution code + re.debug=2 // enable maximum log + println("String: ${txt}") + println("Query : ${re.get_query()}") + re.debug=0 // disable log + start, end := re.match_string(txt) + if start >= 0 { + println("Match ($start, $end) => [${txt[start..end]}]") + } else { + println("No Match") + } + + for name in re.group_map.keys() { + println("group:'$name' \t=> [${re.get_group_by_name(txt, name)}] \ + bounds: ${re.get_group_bounds_by_name(name)}") + } +} +``` + +Output: + +``` +String: http://www.ciao.mondo/hello/pippo12_/pera.html +Query : #0(?Phttps?)|{8,14}#0(?Pftps?)://#1(?P[\w_]+.)+ +Match (0, 46) => [http://www.ciao.mondo/hello/pippo12_/pera.html] +group:'format' => [http] bounds: (0, 4) +group:'token' => [html] bounds: (42, 46) +``` + +In order to simplify the use of the named groups, it is possible to +use a name map in the `re` struct, using the function `re.get_group_by_name`. + +Here is a more complex example of using them: +```v oksyntax +// This function demostrate the use of the named groups +fn convert_html_rgb_n(in_col string) u32 { + mut n_digit := if in_col.len == 4 { 1 } else { 2 } + mut col_mul := if in_col.len == 4 { 4 } else { 0 } + query := '#(?P[a-fA-F0-9]{$n_digit})' + '(?P[a-fA-F0-9]{$n_digit})' + + '(?P[a-fA-F0-9]{$n_digit})' + mut re := regex.regex_opt(query) or { panic(err) } + start, end := re.match_string(in_col) + println('start: $start, end: $end') + mut res := u32(0) + if start >= 0 { + red_s, red_e := re.get_group_by_name('red') + r := ('0x' + in_col[red_s..red_e]).int() << col_mul + green_s, green_e := re.get_group_by_name('green') + g := ('0x' + in_col[green_s..green_e]).int() << col_mul + blue_s, blue_e := re.get_group_by_name('blue') + b := ('0x' + in_col[blue_s..blue_e]).int() << col_mul + println('r: $r g: $g b: $b') + res = u32(r) << 16 | u32(g) << 8 | u32(b) + } + return res +} +``` + +Other utilities are `get_group_by_name` and `get_group_bounds_by_name`, +that return the string of a group using its `name`: + +```v ignore +txt := "my used string...." +for name in re.group_map.keys() { + println("group:'$name' \t=> [${re.get_group_by_name(txt, name)}] \ + bounds: ${re.get_group_bounds_by_name(name)}") +} +``` + + + +### Groups query functions + +These functions are helpers to query the captured groups + +```v ignore +// get_group_bounds_by_name get a group boundaries by its name +pub fn (re RE) get_group_bounds_by_name(group_name string) (int, int) + +// get_group_by_name get a group string by its name +pub fn (re RE) get_group_by_name(group_name string) string + +// get_group_by_id get a group boundaries by its id +pub fn (re RE) get_group_bounds_by_id(group_id int) (int,int) + +// get_group_by_id get a group string by its id +pub fn (re RE) get_group_by_id(in_txt string, group_id int) string + +struct Re_group { +pub: + start int = -1 + end int = -1 +} + +// get_group_list return a list of Re_group for the found groups +pub fn (re RE) get_group_list() []Re_group +``` + +## Flags + +It is possible to set some flags in the regex parser, that change +the behavior of the parser itself. + +```v ignore +// example of flag settings +mut re := regex.new() +re.flag = regex.F_BIN +``` + +- `F_BIN`: parse a string as bytes, utf-8 management disabled. + +- `F_EFM`: exit on the first char matches in the query, used by the + find function. + +- `F_MS`: matches only if the index of the start match is 0, + same as `^` at the start of the query string. + +- `F_ME`: matches only if the end index of the match is the last char + of the input string, same as `$` end of query string. + +- `F_NL`: stop the matching if found a new line char `\n` or `\r` + +## Functions + +### Initializer + +These functions are helper that create the `RE` struct, +a `RE` struct can be created manually if you needed. + +#### **Simplified initializer** + +```v ignore +// regex create a regex object from the query string and compile it +pub fn regex_opt(in_query string) ?RE +``` + +#### **Base initializer** + +```v ignore +// new_regex create a REgex of small size, usually sufficient for ordinary use +pub fn new() RE + +``` +#### **Custom initialization** +For some particular needs, it is possible to initialize a fully customized regex: +```v ignore +pattern = r"ab(.*)(ac)" +// init custom regex +mut re := regex.RE{} +// max program length, can not be longer then the pattern +re.prog = []Token {len: pattern.len + 1} +// can not be more char class the the length of the pattern +re.cc = []CharClass{len: pattern.len} + +re.group_csave_flag = false // true enable continuos group saving if needed +re.group_max_nested = 128 // set max 128 group nested possible +re.group_max = pattern.len>>1 // we can't have more groups than the half of the pattern legth +re.group_stack = []int{len: re.group_max, init: -1} +re.group_data = []int{len: re.group_max, init: -1} +``` +### Compiling + +After an initializer is used, the regex expression must be compiled with: + +```v ignore +// compile compiles the REgex returning an error if the compilation fails +pub fn (re mut RE) compile_opt(in_txt string) ? +``` + +### Matching Functions + +These are the matching functions + +```v ignore +// match_string try to match the input string, return start and end index if found else start is -1 +pub fn (re mut RE) match_string(in_txt string) (int,int) + +``` + +## Find and Replace + +There are the following find and replace functions: + +#### Find functions + +```v ignore +// find try to find the first match in the input string +// return start and end index if found else start is -1 +pub fn (re mut RE) find(in_txt string) (int,int) + +// find_all find all the "non overlapping" occurrences of the matching pattern +// return a list of start end indexes like: [3,4,6,8] +// the matches are [3,4] and [6,8] +pub fn (re mut RE) find_all(in_txt string) []int + +// find_all find all the "non overlapping" occurrences of the matching pattern +// return a list of strings +// the result is like ["first match","secon match"] +pub fn (mut re RE) find_all_str(in_txt string) []string +``` + +#### Replace functions + +```v ignore +// replace return a string where the matches are replaced with the repl_str string, +// this function support groups in the replace string +pub fn (re mut RE) replace(in_txt string, repl string) string +``` + +replace string can include groups references: + +```v ignore +txt := "Today it is a good day." +query := r'(a\w)[ ,.]' +mut re := regex.regex_opt(query)? +res := re.replace(txt, r"__[\0]__") +``` + +in this example we used the group `0` in the replace string: `\0`, the result will be: + +``` +Today it is a good day. => Tod__[ay]__it is a good d__[ay]__ +``` + +**Note:** in the replace strings can be used only groups from `0` to `9`. + +If the usage of `groups` in the replace process, is not needed, it is possible +to use a quick function: + +```v ignore +// replace_simple return a string where the matches are replaced with the replace string +pub fn (mut re RE) replace_simple(in_txt string, repl string) string +``` + +#### Custom replace function + +For complex find and replace operations, you can use `replace_by_fn` . +The `replace_by_fn`, uses a custom replace callback function, thus +allowing customizations. The custom callback function is called for +every non overlapped find. + +The custom callback function must be of the type: + +```v ignore +// type of function used for custom replace +// in_txt source text +// start index of the start of the match in in_txt +// end index of the end of the match in in_txt +// --- the match is in in_txt[start..end] --- +fn (re RE, in_txt string, start int, end int) string +``` + +The following example will clarify its usage: + +```v ignore +import regex +// customized replace functions +// it will be called on each non overlapped find +fn my_repl(re regex.RE, in_txt string, start int, end int) string { + g0 := re.get_group_by_id(in_txt, 0) + g1 := re.get_group_by_id(in_txt, 1) + g2 := re.get_group_by_id(in_txt, 2) + return "*$g0*$g1*$g2*" +} + +fn main(){ + txt := "today [John] is gone to his house with (Jack) and [Marie]." + query := r"(.)(\A\w+)(.)" + + mut re := regex.regex_opt(query) or { panic(err) } + + result := re.replace_by_fn(txt, my_repl) + println(result) +} +``` + +Output: + +``` +today *[*John*]* is gone to his house with *(*Jack*)* and *[*Marie*]*. +``` + + + +## Debugging + +This module has few small utilities to you write regex patterns. + +### **Syntax errors highlight** + +The next example code shows how to visualize regex pattern syntax errors +in the compilation phase: + +```v oksyntax +query := r'ciao da ab[ab-]' +// there is an error, a range not closed!! +mut re := new() +re.compile_opt(query) or { println(err) } +// output!! +// query: ciao da ab[ab-] +// err : ----------^ +// ERROR: ERR_SYNTAX_ERROR +``` + +### **Compiled code** + +It is possible to view the compiled code calling the function `get_query()`. +The result will be something like this: + +``` +======================================== +v RegEx compiler v 1.0 alpha output: +PC: 0 ist: 92000000 ( GROUP_START #:0 { 1, 1} +PC: 1 ist: 98000000 .

a pointer to any `user_data`, it will be passed as the last argument to + each callback. Used for accessing your app context from the different callbacks. +- `init_fn fn(voidptr)` - a callback that will be called after initialization + and before the first event / frame. Useful for initializing any user data. +- `frame_fn fn(voidptr)` - a callback that will be fired on each frame, + at a rate of `frame_rate` frames per second. +`event_fn fn(&Event, voidptr)` - a callback that will be fired for every event received. +- `cleanup_fn fn(voidptr)` - a callback that will be fired once, before the application exits. +- `fail_fn fn(string)` - a callback that will be fired + if a fatal error occurs during app initialization. +- `buffer_size int = 256` - the internal size of the read buffer. + Increasing it may help in case you're missing events, but you probably shouldn't lower + this value unless you make sure you're still receiving all events. In general, + higher frame rates work better with lower buffer sizes, and vice versa. +- `frame_rate int = 30` - the number of times per second that the `frame` callback will be fired. + 30fps is a nice balance between smoothness and performance, + but you can increase or lower it as you wish. +- `hide_cursor bool` - whether to hide the mouse cursor. Useful if you want to use your own. +- `capture_events bool` - sets the terminal into raw mode, which makes it intercept some + escape codes such as `ctrl + c` and `ctrl + z`. + Useful if you want to use those key combinations in your app. +- `window_title string` - sets the title of the terminal window. + This may be changed later, by calling the `set_window_title()` method. +- `reset []int = [1, 2, 3, 4, 6, 7, 8, 9, 11, 13, 14, 15, 19]` - a list of reset signals, + to setup handlers to cleanup the terminal state when they're received. + You should not need to change this, unless you know what you're doing. + +All of these fields may be omitted, in which case, the default value will be used. +In the case of the various callbacks, they will not be fired if a handler has not been specified. + + +#### FAQ + +Q: My terminal (doesn't receive events / doesn't print anything / prints gibberish characters), +what's up with that? +A: Please check if your terminal. The module has been tested with `xterm`-based terminals on Linux +(like `gnome-terminal` and `konsole`), and `Terminal.app` and `iterm2` on macOS. +If your terminal does not work, open an issue with the output of `echo $TERM`. + +Q: There are screen tearing issues when doing large prints +A: This is an issue with how terminals render frames, +as they may decide to do so in the middle of receiving a frame, +and cannot be fully fixed unless your console implements the [synchronized updates spec](https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec). +It can be reduced *drastically*, though, by using the rendering methods built in to the module, +and by only painting frames when your app's content has actually changed. + +Q: Why does the module only emit `keydown` events, and not `keyup` like `sokol`/`gg`? +A: It's because of the way terminals emit events. Every key event is received as a keypress, +and there isn't a way of telling terminals to send keyboard events differently, +nor a reliable way of converting these into `keydown` / `keyup` events. diff --git a/v_windows/v/old/vlib/term/ui/color.v b/v_windows/v/old/vlib/term/ui/color.v new file mode 100644 index 0000000..3e0a0bb --- /dev/null +++ b/v_windows/v/old/vlib/term/ui/color.v @@ -0,0 +1,88 @@ +// radare - LGPL - Copyright 2013-2020 - pancake, xarkes +// ansi 256 color extension for r_cons +// https://en.wikipedia.org/wiki/ANSI_color + +module ui + +const ( + value_range = [0x00, 0x5f, 0x87, 0xaf, 0xd7, 0xff]! + color_table = init_color_table() +) + +[direct_array_access] +fn init_color_table() []int { + mut color_table_ := []int{len: 256} + // ansi colors + color_table_[0] = 0x000000 + color_table_[1] = 0x800000 + color_table_[2] = 0x008000 + color_table_[3] = 0x808000 + color_table_[4] = 0x000080 + color_table_[5] = 0x800080 + color_table_[6] = 0x008080 + color_table_[7] = 0xc0c0c0 + color_table_[8] = 0x808080 + color_table_[9] = 0xff0000 + color_table_[10] = 0x00ff00 + color_table_[11] = 0xffff00 + color_table_[12] = 0x0000ff + color_table_[13] = 0xff00ff + color_table_[14] = 0x00ffff + color_table_[15] = 0xffffff + // color palette + for i in 0 .. 216 { + r := ui.value_range[(i / 36) % 6] + g := ui.value_range[(i / 6) % 6] + b := ui.value_range[i % 6] + color_table_[i + 16] = ((r << 16) & 0xffffff) + ((g << 8) & 0xffff) + (b & 0xff) + } + // grayscale + for i in 0 .. 24 { + r := 8 + (i * 10) + color_table_[i + 232] = ((r << 16) & 0xffffff) + ((r << 8) & 0xffff) + (r & 0xff) + } + return color_table_ +} + +fn clamp(x int, y int, z int) int { + if x < y { + return y + } + if x > z { + return z + } + return x +} + +fn approximate_rgb(r int, g int, b int) int { + grey := r > 0 && r < 255 && r == g && r == b + if grey { + return 232 + int(f64(r) / (255 / 24.1)) + } + k := int(256.0 / 6) + r2 := clamp(r / k, 0, 5) + g2 := clamp(g / k, 0, 5) + b2 := clamp(b / k, 0, 5) + return 16 + (r2 * 36) + (g2 * 6) + b2 +} + +fn lookup_rgb(r int, g int, b int) int { + color := (r << 16) + (g << 8) + b + // lookup extended colors only, coz non-extended can be changed by users. + for i in 16 .. 256 { + if ui.color_table[i] == color { + return i + } + } + return -1 +} + +// converts an RGB color to an ANSI 256-color, approximating it to the nearest available color +// if an exact match is not found +fn rgb2ansi(r int, g int, b int) int { + c := lookup_rgb(r, g, b) + if c == -1 { + return approximate_rgb(r, g, b) + } + return c +} diff --git a/v_windows/v/old/vlib/term/ui/consoleapi_windows.c.v b/v_windows/v/old/vlib/term/ui/consoleapi_windows.c.v new file mode 100644 index 0000000..a6002a6 --- /dev/null +++ b/v_windows/v/old/vlib/term/ui/consoleapi_windows.c.v @@ -0,0 +1,82 @@ +module ui + +union C.Event { + KeyEvent C.KEY_EVENT_RECORD + MouseEvent C.MOUSE_EVENT_RECORD + WindowBufferSizeEvent C.WINDOW_BUFFER_SIZE_RECORD + MenuEvent C.MENU_EVENT_RECORD + FocusEvent C.FOCUS_EVENT_RECORD +} + +[typedef] +struct C.INPUT_RECORD { + EventType u16 + Event C.Event +} + +union C.uChar { + UnicodeChar rune + AsciiChar byte +} + +[typedef] +struct C.KEY_EVENT_RECORD { + bKeyDown int + wRepeatCount u16 + wVirtualKeyCode u16 + wVirtualScanCode u16 + uChar C.uChar + dwControlKeyState u32 +} + +[typedef] +struct C.MOUSE_EVENT_RECORD { + dwMousePosition C.COORD + dwButtonState u32 + dwControlKeyState u32 + dwEventFlags u32 +} + +[typedef] +struct C.WINDOW_BUFFER_SIZE_RECORD { + dwSize C.COORD +} + +[typedef] +struct C.MENU_EVENT_RECORD { + dwCommandId u32 +} + +[typedef] +struct C.FOCUS_EVENT_RECORD { + bSetFocus int +} + +[typedef] +struct C.COORD { + X i16 + Y i16 +} + +[typedef] +struct C.SMALL_RECT { + Left u16 + Top u16 + Right u16 + Bottom u16 +} + +[typedef] +struct C.CONSOLE_SCREEN_BUFFER_INFO { + dwSize C.COORD + dwCursorPosition C.COORD + wAttributes u16 + srWindow C.SMALL_RECT + dwMaximumWindowSize C.COORD +} + +fn C.ReadConsoleInput(hConsoleInput C.HANDLE, lpBuffer &C.INPUT_RECORD, nLength u32, lpNumberOfEventsRead &u32) bool + +fn C.GetNumberOfConsoleInputEvents(hConsoleInput C.HANDLE, lpcNumberOfEvents &u32) bool + +fn C.GetConsoleScreenBufferInfo(handle C.HANDLE, info &C.CONSOLE_SCREEN_BUFFER_INFO) bool diff --git a/v_windows/v/old/vlib/term/ui/input.v b/v_windows/v/old/vlib/term/ui/input.v new file mode 100644 index 0000000..0532b39 --- /dev/null +++ b/v_windows/v/old/vlib/term/ui/input.v @@ -0,0 +1,241 @@ +// Copyright (c) 2020-2021 Raúl Hernández.
