Hi,
My output file:
reg1 {
field a field b
}
reg2 {
field c field d
}
FOREACH ( X IN reg1 ) {
X . a
}
FOREACH ( Y IN reg2 ) {
Now after this if I do ctrl+space I will expect only Y should pop-up. But X and Y both are getting pop-up.
How to restrict X to first FOREACH loop? out of first FOREACH loop X and its value should be erased. Please anyone suggest me how to implement this?
The related grammar rule is:
Model:
entities+=Entity+
uses+=Use+
;
Entity:
name=ID "{"
attributes+=Attr+
"}"
;
Attr:
"field" name=ID
;
Use:
"FOREACH" var=conds "{"
varref=[cond] "." attr=[Attr]
"}"
;
conds:
"(" cond1=cond ")"
| "," cond2=cond
;
cond:
name=ID "IN" entity=[Entity]
;
public class MyDslScopeProvider extends AbstractDeclarativeScopeProvider {
IScope scope_Use_attr(Use ctx , EReference ref) {
return Scopes.scopeFor(ctx.getVarref().getEntity().getAttributes());
}
}
