grammar mixin and inheritance [message #1770993]

I have two different xtext grammars - URDF and Expr - and I want to do a grammar mixin like so:

grammar org.example.urdf.URDF
with org.example.expr.Expr

I have two questions:
1. I guess, I will have to register Expr in the mwe file in my URDF project, but how? Is there any other config needed?

2. How does the inheritance work? More specifically: I had to remove Terminal from URDf in order to be able to mixin Expr. If Expr has org.eclipse.xtext.common.Terminals as mixin - will I be able to ref Terminals from URDF?

You just need to put the first dsl on the classpath of the second

(EG by addding mydsl atop the manifest of mydslb as required bundle

Addditionally you might need a

referencedResource="platform:/resource/xxx.mydsla/model/generated/Mydsla.genmodel"

In the language section of the workflow of mydslb
