Sweet, I'm blown away. I guess it's time to start poking around and seeing how this thing works!
Thanks for the tip.

Along those lines, I have a feature request which I would use frequently, which is that a single file could be multi-mode based on some very simple regular expression matching.
For example, I have lots of files that look like this:

Yes, this is already possible. This is a portion of the LaTeX syntax file:
{ name = 'source.python.embedded.latex'; comment = 'Put the lstlisting match before the moregeneral environment listing. Someday it would be nice to make this rule general enough to figure out which language is inside the lstlisting environment rather than my own personal use for python. -- Brad'; begin = '(\begin{)(lstlisting)(})([(.*)])?'; end = '(\end{)(lstlisting)(})'; captures = { 1 = { name = 'support.function.latex'; }; 2 = { name = 'variable.parameter.latex'; }; 3 = { name = 'support.function.latex'; }; 4 = { name = 'support.function.latex'; }; }; patterns = ( { include = 'source.python'; } ); },
As you can see, the part saying include = 'source.python' will make it so that when in this mode, you are really editing in python, with the full power of the python bundle. So it is just a question of adding your own thing in there, by the appropriate begin,end regex's. This is actually not as hard as it looks, if you read the "syntax highlight" part of the help file, or just look at some example language files. I would guess something like this would work: { name = 'source.c++.embedded.latex'; begin = '^(<<).+(>>)='; end = '^(@)$'; patterns = ( { include = 'source.c++'; } ); },
You'll want to add some capture patterns of course, to color things properly, and maybe finetune the regexs. But the inside should already be colored properly.
