Hi,

I have a model composed of different languages. In one kind of file (workflow) I want to create another file of another language (mask) and reference this via crossreferences.

I have implemented a working solution, but one thing is missing...
The new file is not formatted at all, all content is in the first line.
I create it with:

org.eclipse.emf.common.util.URI uri = workflow.eResource().getURI().trimSegments(1).appendSegment(compound.getName() + ".mask");
XtextResource newResource = (XtextResource) workflow.eResource().getResourceSet().createResource(uri);
newResource.getContents().add(compound);
newResource.save(null);

Can you please give me advice how formatting this whole thing?

Thanks in advance
Markus

you can pass SaveOptions.newBuilder().format().getOptions().toOptionsMap()

did you implement formatter?
does it work if you do it in a unit tests?

Hi Christian,

yes, I implemented a formatter, which works when Trigger Source->Format in editor.

The quickfix itself I have tried in unit test and got the same result.
By the way, I did only test logic called by quickfix itself. Is there an example how I can write a unittest testing quickfix provider?

Thanks
Markus

no i mean:

unit test:
simply call create
add stuff
resource.save(map)

I do the following:

in WorkflowQuickfixProvider I do:
//1. create new EObject: JavaMask mask = MaskFactory.eINSTANCE.createJavaMask()

//2. do some other things with mask....(calling some setters)

//3. Create some resource and add the mask to it
org.eclipse.emf.common.util.URI uri = workflow.eResource().getURI().trimSegments(1).appendSegment(mask.getName() + ".mask");
					XtextResource newResource = (XtextResource) workflow.eResource().getResourceSet().createResource(uri);
					newResource.getContents().add(mask);

//4. Save the new file newResource.save(SaveOptions.newBuilder().format().getOptions().toOptionsMap() );

//5. connect new created mask to a step in workflowFile

//6. Calling builder to resolve references
ResourceSet resourceSet = workflow.eResource().getResourceSet();
					if (resourceSet instanceof XtextResourceSet) {
						XtextResourceSet xtextresourceset = (XtextResourceSet) resourceSet;
						Object classpathURIContext = xtextresourceset.getClasspathURIContext();
						if (classpathURIContext instanceof IJavaProject) {
							IJavaProject project = (IJavaProject) classpathURIContext;
							project.getProject().refreshLocal(IResource.DEPTH_INFINITE, PerfLogFactory.newProgressMonitor());
							project.getProject().build(IncrementalProjectBuilder.INCREMENTAL_BUILD, PerfLogFactory.newProgressMonitor());
						}
						else
							LOGGER.error("ClasspathURIContext of resource " + workflow.eResource().toString() + " was not an javaproject");
					}
					else
						LOGGER.error("resourceset of resource " + workflow.eResource().toString() + " was not an xtextresourceset");



In UnitTest I do..
- Load workflow object from testfile into resourceset
- Create provider like: WorkflowQuickfixProvider provider = new WorkflowQuickfixProvider();
- Call the method, which is also called in @Fix annotated method and contains the logic: provider.addMaskToStep(MaskFactory.eINSTANCE.createJavaMask(), guiStep);
- Afterwards load the created mask file and check content line per line

Hi again christian,

sorry - but meanwhile I found my mistake.....
I bound my formatter in the wrong way:

public Class<? extends JFormattedTextField.AbstractFormatter> bindFormatter() {
return MaskFormatter.class;
}

instead of:

public Class<? extends IFormatter> bindIFormatter() {
return MaskFormatter.class;
}

So - it's not a wonder why it doesn't work :-)
Thanks for your help
Cheers
Markus
