Hi,

In my dsl i would like to extend xbase expressions e.g :

grammar provaxbase.Provaxbase with org.eclipse.xtext.xbase.Xbase

...

Model:
	elements+=Entity*;
	
Entity:
	'entity' '' body = XExpressionInsideBlock ;

MyExpession1 returns xbase::XExpression:
	....
;

Wherever there is XExpression I want to call all xbase parser rules and in addition all my expression rules (e.g MyExpression1)
How can i do?

Hi,

you have to override the rules you want to hook in from the supergrammar.

Need professional support for Xtext, Xpand, EMF?
