Ace editor - Lilypond support

[Erik Nilsson]

Hi, 

I'm considering creating a syntax highlighter for Lilypond code for the Ace 
javascript code editor (http://ace.c9.io/). I think it would be useful for 
tools like for instance weblily (http://www.weblily.net/).

Is there a clear definition of the lilypond language that one could use as the 
basis for such work? Does anybody know of other syntax highlighters out there 
(Frescobaldi, Emacs, Sublime or whatever) that would be a good starting point 
(being fairly complete, readable code). 

Regards,

Erik
