i have this xtext grammar

Program:
'program' name=ID '{'
type=Type
'}'
;

Type:
{Type}
'type' '{'
list+=ListType*
'}'
;

ListType:
name=ID '{'
funcs+=SubType*
'}'
;

SubType:
name=ID '()'
;

Verify:
subsys=[ListType] '.' cname=[SubType] '()'
;

now lets say i do:

program test{

subsystems {
A{
B()
}
}

}

and I want to use Verify rule with something like
A.B()

how can i make it recognize that B is from A ?

Hi,

the keyword for that is called "scoping"

something like (pseudo code)

IScope scope_Verify_cname(Verify ctx, EReference r) {
return Scopes.scopeFor(ctx.getSubsys().getfuncs());
}
