Once you have installed `bat`, +take a look at the ["Using `bat` on Windows"](#using-bat-on-windows) section. + +#### Prerequisites + +You will need to install the [Visual C++ Redistributable](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) package. + +#### With Chocolatey + +You can install `bat` via [Chocolatey](https://chocolatey.org/packages/Bat): +```bash +choco install bat +``` + +#### With Scoop + +You can install `bat` via [scoop](https://scoop.sh/): +```bash +scoop install bat +``` + +#### From prebuilt binaries: + +You can download prebuilt binaries from the [Release page](https://github.com/sharkdp/bat/releases), + +You will need to install the [Visual C++ Redistributable](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) package. + +### From binaries + +Check out the [Release page](https://github.com/sharkdp/bat/releases) for +prebuilt versions of `bat` for many different architectures. Statically-linked +binaries are also available: look for archives with `musl` in the file name. + +### From source + +If you want to build `bat` from source, you need Rust 1.60.0 or +higher. You can then use `cargo` to build everything: + +```bash +cargo install --locked bat +``` + +Note that additional files like the man page or shell completion +files can not be installed in this way. They will be generated by `cargo` and should be available in the cargo target folder (under `build`). + +## Customization + +### Highlighting theme + +Use `bat --list-themes` to get a list of all available themes for syntax +highlighting. To select the `TwoDark` theme, call `bat` with the +`--theme=TwoDark` option or set the `BAT_THEME` environment variable to +`TwoDark`. Use `export BAT_THEME="TwoDark"` in your shell's startup file to +make the change permanent. Alternatively, use `bat`s +[configuration file](https://github.com/sharkdp/bat#configuration-file). + +If you want to preview the different themes on a custom file, you can use +the following command (you need [`fzf`](https://github.com/junegunn/fzf) for this): +```bash +bat --list-themes | fzf --preview="bat --theme={} --color=always /path/to/file" +``` + +`bat` looks good on a dark background by default. However, if your terminal uses a +light background, some themes like `GitHub` or `OneHalfLight` will work better for you. +You can also use a custom theme by following the +['Adding new themes' section below](https://github.com/sharkdp/bat#adding-new-themes). + +### 8-bit themes + +`bat` has three themes that always use [8-bit colors](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors), +even when truecolor support is available: + +- `ansi` looks decent on any terminal. It uses 3-bit colors: black, red, green, + yellow, blue, magenta, cyan, and white. +- `base16` is designed for [base16](https://github.com/chriskempson/base16) terminal themes. It uses + 4-bit colors (3-bit colors plus bright variants) in accordance with the + [base16 styling guidelines](https://github.com/chriskempson/base16/blob/master/styling.md). +- `base16-256` is designed for [base16-shell](https://github.com/chriskempson/base16-shell). + It replaces certain bright colors with 8-bit colors from 16 to 21. **Do not** use this simply + because you have a 256-color terminal but are not using base16-shell. + +Although these themes are more restricted, they have three advantages over truecolor themes. They: + +- Enjoy maximum compatibility. Some terminal utilities do not support more than 3-bit colors. +- Adapt to terminal theme changes. Even for already printed output. +- Visually harmonize better with other terminal software. + +### Output style + +You can use the `--style` option to control the appearance of `bat`s output. +You can use `--style=numbers,changes`, for example, to show only Git changes +and line numbers but no grid and no file header. Set the `BAT_STYLE` environment +variable to make these changes permanent or use `bat`s +[configuration file](https://github.com/sharkdp/bat#configuration-file). + +### Adding new syntaxes / language definitions + +Should you find that a particular syntax is not available within `bat`, you can follow these +instructions to easily add new syntaxes to your current `bat` installation. + +`bat` uses the excellent [`syntect`](https://github.com/trishume/syntect/) +library for syntax highlighting. `syntect` can read any +[Sublime Text `.sublime-syntax` file](https://www.sublimetext.com/docs/3/syntax.html) +and theme. + +A good resource for finding Sublime Syntax packages is [Package Control](https://packagecontrol.io/). Once you found a +syntax: + +1. Create a folder with syntax definition files: + + ```bash + mkdir -p "$(bat --config-dir)/syntaxes" + cd "$(bat --config-dir)/syntaxes" + + # Put new '.sublime-syntax' language definition files + # in this folder (or its subdirectories), for example: + git clone https://github.com/tellnobody1/sublime-purescript-syntax + ``` + +2. Now use the following command to parse these files into a binary cache: + + ```bash + bat cache --build + ``` + +3. Finally, use `bat --list-languages` to check if the new languages are available. + + If you ever want to go back to the default settings, call: + + ```bash + bat cache --clear + ``` + +4. If you think that a specific syntax should be included in `bat` by default, please + consider opening a "syntax request" ticket after reading the policies and + instructions [here](doc/assets.md): [Open Syntax Request](https://github.com/sharkdp/bat/issues/new?labels=syntax-request&template=syntax_request.md). + +### Adding new themes + +This works very similar to how we add new syntax definitions. + +First, create a folder with the new syntax highlighting themes: +```bash +mkdir -p "$(bat --config-dir)/themes" +cd "$(bat --config-dir)/themes" + +# Download a theme in '.tmTheme' format, for example: +git clone https://github.com/greggb/sublime-snazzy + +# Update the binary cache +bat cache --build +``` + +Finally, use `bat --list-themes` to check if the new themes are available. + +### Adding or changing file type associations + +You can add new (or change existing) file name patterns using the `--map-syntax` +command line option. The option takes an argument of the form `pattern:syntax` where +`pattern` is a glob pattern that is matched against the file name and +the absolute file path. The `syntax` part is the full name of a supported language +(use `bat --list-languages` for an overview). + +**Note:** You probably want to use this option as [an entry in `bat`'s configuration file](#configuration-file) +for persistence instead of passing it on the command line as a one-off. Generally +you'd just use `-l` if you want to manually specify a language for a file. + +Example: To use "INI" syntax highlighting for all files with a `.conf` file extension, use +```bash +--map-syntax='*.conf:INI' +``` + +Example: To open all files called `.ignore` (exact match) with the "Git Ignore" syntax, use: +```bash +--map-syntax='.ignore:Git Ignore' +``` + +Example: To open all `.conf` files in subfolders of `/etc/apache2` with the "Apache Conf" +syntax, use (this mapping is already built in): +```bash +--map-syntax='/etc/apache2/**/*.conf:Apache Conf' +``` + +### Using a different pager + +`bat` uses the pager that is specified in the `PAGER` environment variable. If this variable is not +set, `less` is used by default. If you want to use a different pager, you can either modify the +`PAGER` variable or set the `BAT_PAGER` environment variable to override what is specified in +`PAGER`. + +**Note**: If `PAGER` is `more` or `most`, `bat` will silently use `less` instead to ensure support for colors. + +If you want to pass command-line arguments to the pager, you can also set them via the +`PAGER`/`BAT_PAGER` variables: + +```bash +export BAT_PAGER="less -RF" +``` + +Instead of using environment variables, you can also use `bat`s [configuration file](https://github.com/sharkdp/bat#configuration-file) to configure the pager (`--pager` option). + +**Note**: By default, if the pager is set to `less` (and no command-line options are specified), +`bat` will pass the following command line options to the pager: `-R`/`--RAW-CONTROL-CHARS`, +`-F`/`--quit-if-one-screen` and `-X`/`--no-init`. The last option (`-X`) is only used for `less` +versions older than 530. + +The `-R` option is needed to interpret ANSI colors correctly. The second option (`-F`) instructs +less to exit immediately if the output size is smaller than the vertical size of the terminal. +This is convenient for small files because you do not have to press `q` to quit the pager. The +third option (`-X`) is needed to fix a bug with the `--quit-if-one-screen` feature in old versions +of `less`. Unfortunately, it also breaks mouse-wheel support in `less`. + +If you want to enable mouse-wheel scrolling on older versions of `less`, you can pass just `-R` (as +in the example above, this will disable the quit-if-one-screen feature). For less 530 or newer, +it should work out of the box. + +### Indentation + +`bat` expands tabs to 4 spaces by itself, not relying on the pager. To change this, simply add the +`--tabs` argument with the number of spaces you want to be displayed. + +**Note**: Defining tab stops for the pager (via the `--pager` argument by `bat`, or via the `LESS` +environment variable for `less`) won't be taken into account because the pager will already get +expanded spaces instead of tabs. This behaviour is added to avoid indentation issues caused by the +sidebar. Calling `bat` with `--tabs=0` will override it and let tabs be consumed by the pager. + +### Dark mode + +If you make use of the dark mode feature in macOS, you might want to configure `bat` to use a different +theme based on the OS theme. The following snippet uses the `default` theme when in the _dark mode_ +and the `GitHub` theme when in the _light mode_. + +```bash +alias cat="bat --theme=\$(defaults read -globalDomain AppleInterfaceStyle &> /dev/null && echo default || echo GitHub)" +``` + + +## Configuration file + +`bat` can also be customized with a configuration file. The location of the file is dependent +on your operating system. To get the default path for your system, call +```bash +bat --config-file +``` + +Alternatively, you can use the `BAT_CONFIG_PATH` environment variable to point `bat` to a +non-default location of the configuration file: +```bash +export BAT_CONFIG_PATH="/path/to/bat.conf" +``` + +A default configuration file can be created with the `--generate-config-file` option. +```bash +bat --generate-config-file +``` + +There is also now a systemwide configuration file, which is located under `/etc/bat/config` on +Linux and Mac OS and `C:\ProgramData\bat\config` on windows. If the system wide configuration +file is present, the content of the user configuration will simply be appended to it. + +### Format + +The configuration file is a simple list of command line arguments. Use `bat --help` to see a full list of possible options and values. In addition, you can add comments by prepending a line with the `#` character. + +Example configuration file: +```bash +# Set the theme to "TwoDark" +--theme="TwoDark" + +# Show line numbers, Git modifications and file header (but no grid) +--style="numbers,changes,header" + +# Use italic text on the terminal (not supported on all terminals) +--italic-text=always + +# Use C++ syntax for Arduino .ino files +--map-syntax "*.ino:C++" +``` + +## Using `bat` on Windows + +`bat` mostly works out-of-the-box on Windows, but a few features may need extra configuration. + +### Prerequisites + +You will need to install the [Visual C++ Redistributable](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) package. + +### Paging + +Windows only includes a very limited pager in the form of `more`. You can download a Windows binary +for `less` [from its homepage](http://www.greenwoodsoftware.com/less/download.html) or [through +Chocolatey](https://chocolatey.org/packages/Less). To use it, place the binary in a directory in +your `PATH` or [define an environment variable](#using-a-different-pager). The [Chocolatey package](#on-windows) installs `less` automatically. + +### Colors + +Windows 10 natively supports colors in both `conhost.exe` (Command Prompt) and PowerShell since +[v1511](https://en.wikipedia.org/wiki/Windows_10_version_history#Version_1511_(November_Update)), as +well as in newer versions of bash. On earlier versions of Windows, you can use +[Cmder](http://cmder.net/), which includes [ConEmu](https://conemu.github.io/). + +**Note:** The Git and MSYS versions of `less` do not correctly interpret colors on Windows. If you +don’t have any other pagers installed, you can disable paging entirely by passing `--paging=never` +or by setting `BAT_PAGER` to an empty string. + +### Cygwin + +`bat` on Windows does not natively support Cygwin's unix-style paths (`/cygdrive/*`). When passed an absolute cygwin path as an argument, `bat` will encounter the following error: `The system cannot find the path specified. (os error 3)` + +This can be solved by creating a wrapper or adding the following function to your `.bash_profile` file: + +```bash +bat() { + local index + local args=("$@") + for index in $(seq 0 ${#args[@]}) ; do + case "${args[index]}" in + -*) continue;; + *) [ -e "${args[index]}" ] && args[index]="$(cygpath --windows "${args[index]}")";; + esac + done + command bat "${args[@]}" +} +``` + +## Troubleshooting + +### Garbled output + +If an input file contains color codes or other ANSI escape sequences or control characters, `bat` will have problems +performing syntax highlighting and text wrapping, and thus the output can become garbled. +When displaying such files it is recommended to disable both syntax highlighting and wrapping by +passing the `--color=never --wrap=never` options to `bat`. + +### Terminals & colors + +`bat` handles terminals *with* and *without* truecolor support. However, the colors in most syntax +highlighting themes are not optimized for 8-bit colors. It is therefore strongly recommended +that you use a terminal with 24-bit truecolor support (`terminator`, `konsole`, `iTerm2`, ...), +or use one of the basic [8-bit themes](#8-bit-themes) designed for a restricted set of colors. +See [this article](https://gist.github.com/XVilka/8346728) for more details and a full list of +terminals with truecolor support. + +Make sure that your truecolor terminal sets the `COLORTERM` variable to either `truecolor` or +`24bit`. Otherwise, `bat` will not be able to determine whether or not 24-bit escape sequences +are supported (and fall back to 8-bit colors). + +### Line numbers and grid are hardly visible + +Please try a different theme (see `bat --list-themes` for a list). The `OneHalfDark` and +`OneHalfLight` themes provide grid and line colors that are brighter. + +### File encodings + +`bat` natively supports UTF-8 as well as UTF-16. For every other file encoding, you may need to +convert to UTF-8 first because the encodings can typically not be auto-detected. You can `iconv` +to do so. +Example: if you have a PHP file in Latin-1 (ISO-8859-1) encoding, you can call: +``` bash +iconv -f ISO-8859-1 -t UTF-8 my-file.php | bat +``` +Note: you might have to use the `-l`/`--language` option if the syntax can not be auto-detected +by `bat`. + +## Development + +```bash +# Recursive clone to retrieve all submodules +git clone --recursive https://github.com/sharkdp/bat + +# Build (debug version) +cd bat +cargo build --bins + +# Run unit tests and integration tests +cargo test + +# Install (release version) +cargo install --path . --locked + +# Build a bat binary with modified syntaxes and themes +bash assets/create.sh +cargo install --path . --locked --force +``` + +If you want to build an application that uses `bat`s pretty-printing +features as a library, check out the [the API documentation](https://docs.rs/bat/). +Note that you have to use either `regex-onig` or `regex-fancy` as a feature +when you depend on `bat` as a library. + +## Contributing + +Take a look at the [`CONTRIBUTING.md`](CONTRIBUTING.md) guide. + +## Maintainers + +- [sharkdp](https://github.com/sharkdp) +- [eth-p](https://github.com/eth-p) +- [keith-hall](https://github.com/keith-hall) +- [Enselic](https://github.com/Enselic) + +## Security vulnerabilities + +Please contact [David Peter](https://david-peter.de/) via email if you want to report a vulnerability in `bat`. + +## Project goals and alternatives + +`bat` tries to achieve the following goals: + +- Provide beautiful, advanced syntax highlighting +- Integrate with Git to show file modifications +- Be a drop-in replacement for (POSIX) `cat` +- Offer a user-friendly command-line interface + +There are a lot of alternatives, if you are looking for similar programs.
