Syntax highlighting code with Javascript [closed]

StackOverflow uses the Prettify library.

I recently developed one called rainbow.

The main design goal was to make the core library really small and make it really easy for developers to extend.

See http://rainbowco.de.

SyntaxHighlighter is available as a GitHub project.

jQuery Syntax Highlighter is a new one based on Google's Prettify - a really really really popular plain javascript syntax highlighter.

It supports such things as code and pre blocks, able to use classnames like language-javascript to indicate we want it to highlight, as well as wordwrap. You can copy and paste code by selecting it normally instead of having to open a raw view like many others. It can be further customised by using the HTML5 data attribute data-sh or via specifying options at initialisation. A great stable choice which is updated regularly.

What about Prism by Lea Verou.

From her blog post announcement in June (2012):

• It’s tiny. The core is only 1.5KB minified & gzipped.
• It’s incredibly extensible. Not only it’s easy to add new languages (that’s a given with every syntax highlighter these days), but also to extend existing ones.
• It supports parallelism through Web Workers, for better performance in certain cases.
• It doesn’t force you to use any Prism-specific markup, not even a Prism-specific class name, only standard markup you should be using anyway. So, you can just try it for a while, remove it if you don’t like it and leave no traces behind.
