Scope Provider: Context [message #763875]

Hi,

I am currently implementing my own scope provider. To create my scope, I need to know the "context" around it. Lets say my DSL looks something like that:

namespace A {
   // invoke scope provider here for some cross reference, e.g. for auto-completion
}

The scope provider gets the context (the Xtext resouce) and the EReference as input. What I need additionally is the name of the outer namespace, in this case "A" in order to provide my scope. As far as I know, I cannot get this information out of the two parameters (please correct me if I am wrong).

What do I have to do, to get the "A" when invoking the scope-provider withing the namespace?

Regards,

Thomas

Hi,

i do not understand your question. here is the IScopeProvider interface

public interface IScopeProvider {

	IScope getScope(EObject context, EReference reference);

}

it has everything you need. you can walk up the context and its econtainers to find out where you are.

so could you elaborate what you exactly want to do what
is not given by the default implementation and its hooks for customization?

never the less resource.getContents().get(0) gives you the model root.

Hello,

I was somehow focused on the IGlobalScopeProvider... Everything is fine with the "normal" IScopeProvider. Gives me exactly what I want.

Thanks a lot!
