In Xtext, How to define terminal with same definition? Or Circumvent EString requirement in crosslinking?

Question

I have the following grammar defined in XText.

Object:
    "object" (name=INT)? ("extends" superType=[Object|INT] "{" 
        (comps+=Component)* 
    "}"
;

I'm having problems defining the cross-reference since apparently INT does not return an ecore::EString object.

I tried defining an STRINT terminal:

STRINT returns ecore::EString:
    INT
;

However this hides the INT terminal previously defined, which is another problem.

Questions:

• Is there a way to define a new terminal with the same pattern as another and not hide the first one?
• Are there workarounds for this ecore::Estring issue, because I want to use an integer for crosslinking.

Answer 1

If you define STRINT as a data type rule, it'll not hide another terminal. So basically what you described will work:

STRINT:
  INT
;
