语法高亮工具Pygments

Posted on by

天天写代码， 天天看代码，没有颜色的代码看久了自然会眼花，于是各种高亮工具诞生了。基本上每个IDE都集成了代码语法高亮着色器，在Web应用里面，代码着色可以在用户端用JavaScript实现也可以在服务器端实现，PHP实现的着色工具最多，可惜俺不会，找啊找啊找到了这款神奇的代码语法着色器Pygments，支持很多语言（有一多半语言我都只听说过），俺够用了，而且是Python写的，方便偶在GAE里面折腾。
官方地址：http://pygments.org/

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, wikis or other applications that need to prettify source code.

偶继续折腾GAE
