Syntax Highlighting library in ActionScript

Question

I let user enter some code in my Flex3 (Flash 10) app and I want to do syntax highlighting.

Is there any open-source library that would help me?

I'll need a Lua syntax support, but I can add it myself if library has a resonable interface to do this.

Check out Anirudh's port of google-code-prettify to ActionScript3, it has a very good example app as well.
