Hello all,

I am trying to use syntactic predicates in Xtext and I am using ANTLR WORKS to help me visualize my rules diagrams. I want to know how can I make this syntactic predicate using Xtext

(rule_name ':') => rule_label

Thanks,

Hi,

did you have a look at the section "Syntactic Predicates" in the xtext docs? it should be pretty the same

Yes I surely did,
I know how to add syntactic predicate for some rules all together , but the one I mentioned is different, I want it to be as if I am saying when u find rule_name followed by a ':' go to rule_label
This is different from the normal syntactic predicates for rules
