Issue with KDevelop: Is it using different parsers in parallell for different puropuses?

Kate already has it. It's implemented and I don't see it being reworked any 
time soon, unless a volunteer steps up to the plate. Calling it a parsing 
engine is buzzowordiness to me. It's a simple state machine coupled to a 
pattern matcher. Simplicity is the key word here.

It works pretty well considered how simple it is. It *is* langauge aware. Have 
you seen how many languages Kate's highlighter supports? All of those 
highlight fine in KDevelop as well. I have projects where the test harness 
has quite a bit of Octave and Common Lisp code in them, and Kdevelop (via 
KatePart (?)) hightlights those sources just fine. Have you actually tried 
what you're talking about?

The only thing, I gather, that KDevelop may potentially do is override the 
highlighting for files it knows how to highlight better than what Kate does. 
That more powerful highlighting functionality could be potentially put into a 
separate framework and made useable by Kate (and other applications), but 
again -- someone has to design it and code it first. I suggest you give it a 
try if you place such a high value on that feature (as you claim).

Cheers, Kuba
