+# web_crawler
+web_crawler is a very simple web crawler.  
+This web crawler fetches news from tuicool.com,
+(a chinese site similar to hacker-news.firebaseio.com).  
+
+# Compile and Run
+
+Use this to generate an executable, and then launch the web crawler:
+```bash
+v web_crawler.v
+./web_crawler
+```
+
+And this to compile and launch the web crawler directly:
+```bash
+v run web_crawler.v
+```
+
+This project shows how to use http.fetch() to get http.Response, 
+and then html.parse() to parse the returned html.
+
+It's easy, isn't it?
