Reusing KHTMLs CSS parser for a KDevelop language plugin

[Milian Wolff]

Hello!

Sooner or later I want to start on a language plugin to add CSS support to 
KDevelop (and eventually Quanta).

For that I need a tokenizer and a parser. So far, each language plugin in 
KDevelop uses an AST and the Visitor concept to build the DUChain. As I've 
never used Flex myself, and am by far no expert in parsers, does the CSS 
parser support the Visitor concept?

Nevertheless, I'd like to at least reuse the tokenizer from kdelibs and would 
write a grammar for Kdevelop-pg-qt to get a parser with an AST.

I had a quick look at kdelibs/khtml/css and I see that neither the parser, nor 
the tokenizer gets installed. Of course, this makes sense if noone uses it 
outside of KHTML. Could this be changed? Or would those classes then have to 
stay BC and this is not possible/wanted for such internal classes?


Alternatively to the above, are there maybe KHTML APIs I can use that give me 
a low-level analysis of a given CSS file? I'd need e.g. a list of rule 
definitions, imports, charset statements, together with line numbers where they 
occur. That should actually be enough to build a DUChain.

Note that most of the above could be applied to other languages as well, most 
notably JavaScript/ECMA Script and XML/HTML/XHTML.

Thanks and have a nice day
