I’d like to request syntax highlighting for AutoIt (http://www.autoitscript.com). There is already plenty of syntax highlighting files out there for the language, it would simply be a matter of tweaking the format of one of these files to match whatever format your lexer uses.
the syntax highlighting languages come from the library http://projects.gnome.org/gtksourceview/
in version 2.x (for gtk 2.x) then it should be possible to add new languages reading the documentation. I’ll add to the TODO list but don’t know when I’ll have time to take care.
The list of available languages comes directly from a call to the library at application start. I’s not hardcoded and there’s no file to edit. All you have to do is to add the language to the installed library (I can’t help you with this now), cherrytree will then see it and list it.
