Semantic Highlighting and ANTLR Parser [message #18173]

Hello

I'm trying to create a DLTK based language plugin for eclipse. I have
several problems with Semantic Highlighting and the ANTLR Parser. One thing
is, that I dont't understand how the interfaces for Semantic Highlighting
should work, and what the methods are for. And the other thing is, that I
don't know wheater I need an AST for Semantic Highlighting or not. I would
be pleased if you can help me.

Thanks

Hi Sebastian,

To add sementic highlighting you need to extend class PositionUpdater
with your implementation and return it from your TextTools class.
(Please see XOTclTextTools for example).

AST aren't required for samantic highlighting, but it very useful.
If you have position information without AST, it will be enough.

Please look at class XOTclSemanticPositionUpdater from Eclipse DLTK CVS
(org.eclipse.dltk.xotcl.ui project) as a refer implementation.

Best regards,
Andrei.
