I guess html will come in next development cycle - it will need major refactoring of syntax highlighting mechanism (it is now pretty much tied to curly braces languages...).

Funny coincidence: Just a few days before you announced the JS highlighting, I thought that it might be fun to reimplement CodeEditor to support user-defined highlighting. I even started working on it in my free time, so here is a little tasting:
index.php?t=getfile&id=3785&private=0

The image shows CodeEditor using the highlight definition file specifying highlighting of higlighting definition files to highlight highlight definition file specifying highlighting of higlighting definition files. Pretty meta, right? Very Happy

It is based on pcre and caching. Basic highlighting works just fine, some of the higher level features (scope highlighting, matching brackets, ...) are not yet implemented and some are using the old CodeEditor code. The goal is to allow loading user specified highlighters, both at compile time (by include) and at run-time. It requires some pcre skill (or copy&paste skill Smile

) to write one, but otherwise it is very simple format as you can see above - it takes only 16 lines to describe C++ Smile

This file imitates current CodeEditor:

If there is anyone interested in more details we can discuss it in separate thread Wink
