It’s getting pretty awesome. The editor does syntax highlighting and on the fly compilation and error underlining. JWS here:

Looking at this and your other projects on Google Code, Nate you are amazing! ;D
How did you do the syntax highlighting and line numbering?
Thanks. 
It was done in one evening using RSyntaxTextArea and Ragel. The Ragel code for it is here. Ragel is super cool, I’m finding more uses for it all the time.
