I just finished a new project called HighlightMyCode. The goal is simple: to provide Syntax highlighting for your code snippets on the fly. Just paste your code, select a language and a theme and you’re done. You’ll get a small piece of javascript to embedded your highlighted snippet on your site.
It’s basically the same idea as a Pastebin, but with emphasis on Syntax Highlighting (right now there are 4 themes available, and it’s easy to submit new ones).
The site is powered by GeSHI for syntax highlighting and uses Boilerplate, a tiny CSS framework, for it’s template.
Here’s a demo:
Give it a try! It’s fun: http://www.highlightmycode.com
