link reference issue [message #760435]

Hi!

I have some rule like

Function: Clause (';' Clause)* '.' ;
Clause: ID '(' Args ')' '->' Expressions ;

Each clause has the same name (ID) and it actually belongs naturally to the function itself. Is there a way to let the function inherit the name from the first clause without changing the grammar?

The grammar change feels inelegent

Function: ID Clause0 (';' Clause)* '.' ;
Clause0 returns Clause: '(' Args ')' '->' Expressions ;
Clause: ID '(' Args ')' '->' Expressions ;

best regards,
Vlad

Hi,

am not sure what you exactly want to do since you dont have any assignments in your grammar which is abolutely unrealisitic. never the less if you want to calculate a qualified name (the thing that is used for cross references) with a custom logic this is usually done in the IQualifiedNameProvider. so subclassing and customizing DefaultDeclarativeQualifiedNameProvider should do the trick.

Hi Christian!

Well the example was stripped down of assignments, of course they are present in the full grammar.

Thanks a lot for the pointers, I will look at IQualifiedNameProvider. I suppose it's the same place to look at if the references are not just names but may be more complicated expressions?

best regards,
Vlad
