Cross references in multiple files [message #1728366]

Hi,
Here is grammar:

MyModel:
	(imports+=Import)*
	(entities+=Entity)*;

Import:
	'import' importURI=STRING;

Entity:
	'entity' name=ID ('extends' extends=[Entity|ID])?;

[first.dsl]

entity Base

[second.dsl]

import "first.dsl"

entity Entity extends Base

but `Base` highlighted in red with error message: "Couldn't resolve reference to Entity 'Base'"

I've read few topics about this there was an advice to include the following lines to mwe2

 fragment = scoping.ImportURIScopingFragment {}
 fragment = exporting.SimpleNamesFragment {}

if I right understand there is no more ImportURIScopingFragment but only
ImportNamespacesScopingFragment2

what should I do to enable cross reference?
I'm using xtext 2.9.2

Thanks

Hi,

you can add the bindings manually

class MyDslRuntimeModule extends AbstractMyDslRuntimeModule {
	
	override bindIGlobalScopeProvider() {
		ImportUriGlobalScopeProvider
	}
	
	override configureIScopeProviderDelegate(Binder binder) {
		binder.bind(IScopeProvider).annotatedWith(Names.named(AbstractDeclarativeScopeProvider.NAMED_DELEGATE))
			.to(SimpleLocalScopeProvider);
	
	}
	
}

please add a bug/enhancement request to support this via fragment as well.

p.s.:

having an import still requires to load all resources to the resourceset in standalone case
