Just completed an Actionscript 3.0 Language file for GeSHi. Pretty simple to put together, but fairly time consuming going through the Actionscript 3 documentation at Adobe.com and parsing through all the functions, classes, keywords, etc.

I should have the file up and ready for download soon. I still have a few tweaks to make so that everything parses correctly. Namely, reverse ordering the keywords. I'll have to write an automated script to do that. However, for now you can see an example of it in action. Just check out my Actionscript 3.0 — Full-screen Centered Flash post.

I'm using the CodeHighlighter plug-in on my site which uses GeSHi 1.0.7.17.

***UPDATE***

I've included the AS3 Language file here: GeSHi AS3 Language File v0.5
