Description for the Content Assist of File Cross-References [message #1860111]

Hello,

I was wanting to know whether it is possible to have a description for the content assist of references. For example in the simple grammar below:

Model:
greetings+=Greeting*;

Greeting:
'Hello' name=ID '!';

References:
'ref' greeting=[Greeting];

And I have a file A:
Hello World1 !

And in file B:
Hello World2 !

Is it possible to have the content assist display a description like World1 :File A and World2 :File B for Reference?

Thank you,
Atul

starting point

public class MyDslProposalProvider extends AbstractMyDslProposalProvider {
	
	protected StyledString getStyledDisplayString(IEObjectDescription description) {
		StyledString styledDisplayString = getStyledDisplayString(description.getEObjectOrProxy(),
			getQualifiedNameConverter().toString(description.getQualifiedName()),
			getQualifiedNameConverter().toString(description.getName()));
		StyledString append = styledDisplayString.append(" - " + description.getEObjectURI().trimFragment());
		return append;
	}
}

Hello,

For the same example grammar,
If file A contains:
Hello World1 !

And File B contains:
Hello World1 !

Is it possible that if I refer it from file A, can the qualified names in the content assist come as World1 which refers to file A and fileB.World1 which refers to file B?

Thank you,
Atul

Hello,

If there are two references with the same name in different files, the default scope takes only the first reference. Is there a way to provide a qualified name to the other reference similar to <filename>.<reference>?

If File A contains:
Hello World1 !

And File B also contains:
Hello World1 !

So if i do ref, I should get World1 and FileB.World1 as the possible references instead of just World1.

Thank you,
Atul

you can adapt IQualifiedNameProvider to encode file name into elements name.
but then you also need to allow file names in the reference

SomeObject: ref=[SomeType|FQN];

FQN: ID ("." ID)*;

Hello,

Yes. But how do i encode the file name only for the duplicate elements and not all the elements?

this would be more compilated.
you would need to query the scope for all elements and transform it.

unfortunately there is not ootb example
