Think Twice Code Once

Craig Campbell, an employee at Vimeo, has created a very easy to use, lightweight (~3k) code syntax highlighting library
written in JavaScript. Out of the box, Rainbow supports syntax highlighting for the following languages:

• JavaScript, HTML, CSS, PHP, Python, Ruby, C, Shell, Scheme, Lua, C#

Adding support for your own languages is very easy, however, and theming is done entirely with CSS. If you don’t want to sweat the details of theming, you can use one of their many built-in themes (like the very popular solarized theme).
