Linking in external file [message #1784344]

Hello,

I am trying to open a model file using File->Open file from menu.
File is in C:\Temp\test.MyDsl
File opened in editor.
But linking is not working.
If I click on reference, its not going to definition.

Sample grammar.
Clicking on Test under group is not going to its definition.

virag 1
Test 2

Group{
	Test
}

Kindly help me with this.
I am expecting these cross reference should work.
Thanks in advance.

Best regards,
Virag Purnam

this is not intended to work. opening files from outside eclipse is view only => you need projects

Thanks for the reply.
I checked the same behaviour with external java file and tried opening with eclipse.
It opens and local references works fine in .java file.
Can we achieve same with model file? (Only local references)

yes you need to customize the opener

import org.apache.log4j.Logger;
import org.eclipse.core.filesystem.EFS;
import org.eclipse.core.filesystem.IFileStore;
import org.eclipse.core.runtime.Path;
import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.common.util.WrappedException;
import org.eclipse.emf.ecore.EReference;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IWorkbench;
import org.eclipse.ui.IWorkbenchPage;
import org.eclipse.ui.PartInitException;
import org.eclipse.ui.ide.FileStoreEditorInput;
import org.eclipse.ui.ide.IDE;
import org.eclipse.xtext.ui.editor.LanguageSpecificURIEditorOpener;
import org.eclipse.xtext.ui.editor.utils.EditorUtils;

import com.google.inject.Inject;

public class MyDslLanguageSpecificURIEditorOpener extends LanguageSpecificURIEditorOpener {
	
	private static final Logger logger = Logger.getLogger(MyDslLanguageSpecificURIEditorOpener.class);
	
	@Inject(optional = true)
	private IWorkbench workbench;
	
	@Override
	public IEditorPart open(URI uri, EReference crossReference, int indexInList, boolean select) {
		IEditorPart result = super.open(uri, crossReference, indexInList, select);
		if (result == null && uri.isFile()) {
			try {
				IFileStore fileStore =  EFS.getLocalFileSystem().getStore(new Path(uri.toFileString()));
				FileStoreEditorInput editorInput = new FileStoreEditorInput(fileStore);
				IWorkbenchPage activePage = workbench.getActiveWorkbenchWindow().getActivePage();
				final IEditorPart editor = IDE.openEditor(activePage, editorInput, getEditorId());
				selectAndReveal(editor, uri, crossReference, indexInList, select);
				return EditorUtils.getXtextEditor(editor);
			} catch (WrappedException e) {
				logger.error("Error while opening editor part for EMF URI '" + uri + "'", e.getCause());
			} catch (PartInitException partInitException) {
				logger.error("Error while opening editor part for EMF URI '" + uri + "'", partInitException);
			}
		}
		return result;
	}

}

class MyDslUiModule extends AbstractMyDslUiModule {

	override void configureLanguageSpecificURIEditorOpener(com.google.inject.Binder binder) {
		if(PlatformUI.isWorkbenchRunning()) binder.bind(IURIEditorOpener).annotatedWith(LanguageSpecific).to(
			MyDslLanguageSpecificURIEditorOpener)
	}
}

Hi Mr, Christian Dietrich,

Binding is done.
But still local references are not working.
I mean on click it is not going to definition.

what can be the mistake on my code ?

Thanks and regards,

Here i have attached a sample project and sample file.
Please keep the file some where in system. e.g c:\temp\test.MyDsl

Open file using File->Open file and provide the path. e.g c:\temp\test.MyDsl
Expectation is that, local reference linking should work.

Thanks and regards,
