CodeHighlighter is an extension for Safari and Chrome that does syntax coloring for the code examples contained in Apple's developer documentation under developer.apple.com. This is done using Zepto.js and highlight.js.
To build the extension, you need Node.js and CoffeeScript. Run cake at the
root of the cloned repo (where Cakefile resides) for the available commands.
The build products will go in their respective locations under safari/ and
chrome/.
You will have to package the build products into distributable form by using Extension Builder (Safari) and Extension Management (Chrome). See Apple's and Google's developer documentation for details.
