Hi all,

I create atl plug-in project for invoke transformation programmaticaly. First i

create command and i invoke this command from file right click and generate button.

But i cant run transformation i always get error.When i debug i see asm variable

always null and error occurs because of this. My code and error is blow

Not i use xtext as a input

Anyone can help me to fix this ?

Code;

public class deneme {

public static void aaa(String filepath, String outPutFilePath) throws ATLCoreException, IOException {
		 // Replace DSL by your Language name
		FilesystemStandaloneSetup dsl = new FilesystemStandaloneSetup();		
		Injector injector = dsl.createInjectorAndDoEMFRegistration();
		XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
		resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
		Resource resource = resourceSet.getResource(URI.createURI(filepath), true);
		
		// Create factory and injector
		EMFModelFactory factory = new EMFModelFactory();
		EMFInjector emfinjector = new EMFInjector();
		// Load the DSL metamodel
		EMFReferenceModel dslMetamodel = (EMFReferenceModel) factory.newReferenceModel();
		emfinjector.inject(dslMetamodel, "File://C:\\Users\\unituser\\XtextAndGmfSynchronization\\org.eclipse.m2m.atl.filesystem\\model\\Filesystem.ecore");
		// Load the XtextResource as an EMFModel
		EMFModel model = (EMFModel) factory.newModel(dslMetamodel);
		emfinjector.inject(model, resource);
 
		EMFReferenceModel outMetamodel = (EMFReferenceModel) factory.newReferenceModel();
		emfinjector.inject(outMetamodel, "File://C:\\Users\\unituser\\XtextAndGmfSynchronization\\org.eclipse.m2m.atl.filesystem\\model\\filesystem2.ecore");
		EMFModel outModel = (EMFModel) factory.newModel(outMetamodel);
		
		EMFVMLauncher launcher = new EMFVMLauncher();
		launcher.initialize(Collections.<String, Object> emptyMap());
		
		launcher.addInModel(model, "IN", "Filesystem");
		launcher.addOutModel(outModel, "OUT", "filesystem2");
		
		InputStream asm = deneme.class.getResourceAsStream("org.eclipse.m2m.atl.filesystem/files/transformation.asm"); 
		
		launcher.launch(
				ILauncher.RUN_MODE, 
				new NullProgressMonitor(), 
				Collections.<String, Object> emptyMap(),
				new Object[] {asm} );
		
		outModel.getResource().setURI(URI.createURI(outPutFilePath));
		outModel.getResource().save(Collections.EMPTY_MAP);
	}
}

Hello,

Before generating the ATL plugin, have you already tried to run your transformation manually in your development workbench using an ATL launch configuration?
If this works, have you actually generated your ATL plugin from this launch configuration?
This could help to identify whether the problem comes from the generated Java launcher or from the transformation itself.

Hi,

yes i tried to run my transformation manually and it have been worked perfect (i use

non xtext resource just use emf resource for manually). But i must use xtext as input

file so i think i cant use raw atl plug-in i tihnk i must change its run method (like

my above method). Because i tried this too and it have not been worked. It gives me

error like your input file not emf resource

Regards

Maybe your problem is not related to ATL itself, but more to how you can load an Xtext Resource as a standard EMF Resource.
You should ask a specific question about this onto the Xtext (and/or EMF) forum.
