Default import [message #733775]

I have a language which reads variable declarations from a separate fixed file. So A.mydsl, B.mydsl, and C.mydsl all look at a file called Types.mydsl. The problem is that they don't explicit reference that file. If I add an explicit reference using

'import' importURI=STRING

and add the corresponding 'import' declaration to each file then everything works fine. Is there a way to get this behavior without requiring an explicit import? The file is always called Types.mydsl and is always located in the same directory as the mydsl file which uses the types.

Thanks,
Andrew

Hi,

what about a implicit explicit import? have a look at ImportUriGlobalScopeProvider / ImportUriResolver

Hi Christian,

Thank you for the quick reply. I created a subclass of ImportUriGlobalScopeProvider which tries to insert the Types.mydsl file automatically:

public class MydslImportUriGlobalScopeProvider extends
		ImportUriGlobalScopeProvider {
	
	@Override
	protected LinkedHashSet<URI> getImportedUris(final Resource resource) {
		LinkedHashSet<URI> temp = super.getImportedUris(resource);
		temp.add(URI.createURI("Types.mydsl"));
		return temp;
	}
	
}

and in my MydslRuntimeModule I now have:

	@Override
	public Class<? extends IGlobalScopeProvider> bindIGlobalScopeProvider() {
		return MydslImportUriGlobalScopeProvider.class;
	}

Everything seems to work. I didn't see a correspond bind method to override the resolver, but it appears that I don't need to create my own anyway.

Thanks,
Andrew
