project wizard and launch configuration [message #559291]

Hi every body.
I have created a language with Xtext and it generate java classes with XPand.

in the workflow, I have uncommented these lines :

fragment = projectWizard.SimpleProjectWizardFragment {
					generatorProjectName = "${projectName}.generator" 
					modelFileExtension = file.extensions
			 }

(modelFileExtension is 'adapt')

So now, the user can create a project for my language.
but I would like that when he create a '<name>.adapt' file, he has just to do : right ciick-> run as -> launch configuration. (the same thing as the workflow files.)

Is it possible to do something like that?

Until now, I generate a java file which can launch the workflow.

Thanks,

Jérémie.

This is called "context menus" and described in section 7.5.3 of the Xtext 1.0.1 User Guide. Note that the description is far from a full tutorial so you might want to Google for additional info which is non-Xtext specific. The problem essentially is divided into registering the context menu item and executing it -for the latter you'll have to know how to run the generator workflow programmatically, which you apparently already know.

Hi,

I am close to resolve the problem :

To add a menu, I add this in the plugin..xml of the ui project :

<!--  popup menu -->
<extension
         point="org.eclipse.ui.commands">
      <command
            description="Trigger expensive validation"
            id="fr.irisa.cairn.graphAdapter.Language.generateAdapter"
            name="generate adapter">
      </command>
 </extension>
 
 <extension
  point="org.eclipse.ui.handlers">
  <handler
    class="fr.irisa.cairn.graphAdapter.ui.GraphAdapterGeneratorHandler"
    commandId="fr.irisa.cairn.graphAdapter.Language.generateAdapter">
  </handler>
</extension>

  <extension point="org.eclipse.ui.menus">
        <menuContribution
            locationURI="popup:#TextEditorContext?after=group.edit">
             <command
                 commandId="fr.irisa.cairn.graphAdapter.Language.generateAdapter"
                 style="push"
                 tooltip="generate the graph adapter">
            <visibleWhen checkEnabled="false">
                <reference
                    definitionId="fr.irisa.cairn.graphAdapter.Language.Editor.opened">
                </reference>
            </visibleWhen>
         </command>  
         </menuContribution>
    </extension>

and I have created an Handler class which look like this :

public class GraphAdapterGeneratorHandler extends AbstractHandler {

//	private final static String MODEL_PATH = "src/model/";
	private final static String JAVA_PATH = "src-gen/";
	private final static String ENCODING = "UTF-8";

	// @Override
	public Object execute(ExecutionEvent event) throws ExecutionException {
		IFile adapterFile = getFilePath(event);
		String modelPath = adapterFile.getProjectRelativePath().toOSString();
		System.out.println("MODEL_PATH = " + modelPath);
		GraphAdapterGenerator.generate(modelPath, JAVA_PATH, ENCODING);
		return null;
	}

and to launch the workflow, i have this int
the GraphAdapterGenerator class :

Mwe2Launcher.main(new String[] { "workflow.LanguageGenerator", "-p",
				"modelPath=".concat(absoluteModelDir), "-p",
				"targetDir=".concat(absoluteTargetDir), "-p",
				"fileEncoding=".concat(this.encoding)
				});

unfortunately it doen't work : when I run the generator project and create a new adapter project, if i want to lanch the generation, I have this exception:

0    [Thread-0] ERROR org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher  - Couldn't find module with name 'workflow.LanguageGenerator'.

That's strange because I still van launch the generation by a "manual way"
when I crete an adapter project, in the project I have this java file :

public class AdapterGenerator {
	private final static String MODEL_PATH = "src/model/Model.adapt";
	private final static String JAVA_PATH = "src-gen/";
	private final static String ENCODING = "UTF-8";

	public static void main(String[] args) {
		AdapterGenerator.generate();
	}
	
	public static void generate() {
		GraphAdapterGenerator.generate(MODEL_PATH, JAVA_PATH, ENCODING);
	}
}

This class replace the GraphAdapterGeneratorHandler class. And If I launch this file, the generation works.
.
For me, the 2 ways should works, but no.
Have you got any ideas?

This "usually" is a problem with location of the workflow file and whether that's resolved against the classpath or through a plugin-based URI.

Maybe you have to use something like "platform:/plugin/<your plugin ID>/workflow/&c" to get it to work. I usually end up using the debugger to see at a fairly low level how the file is looked up.

I tried to use de debugger, but I don"t have source for the Mwe2Launcher class, so it is not really clear what append in this class.
I tried to this :

Mwe2Launcher.main(new String[] { "platform:/plugin/fr.irisa.cairn.graphAdapter.language.generator/src/workflow/LanguageGenerator.mwe2", "-p",
				"modelPath=".concat(absoluteModelDir), "-p",
				"targetDir=".concat(absoluteTargetDir), "-p",
				"fileEncoding=".concat(this.encoding)
		// "tomPath=".concat(absoluteAdapterDir) });
				});
	}

but I have the same exception :

1    [Thread-0] ERROR org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher  - Couldn't find module with name 'workflow.LanguageGenerator'.
java.lang.IllegalArgumentException: Couldn't find module with name 'workflow.LanguageGenerator'.

But there is a difference, if I launch the generation with the old way, I have now, this exception :

MODEL_PATH = src/model/Model.adapt
1    ERROR Mwe2Launcher       - java.net.MalformedURLException: unknown protocol: platform

	... 9 more

I don't understand why it is not the same comportement for the both way.

maybe an important things, these line :

Mwe2Launcher.main(new String[] { "workflow.LanguageGenerator", "-p",
				"modelPath=".concat(absoluteModelDir), "-p",
				"targetDir=".concat(absoluteTargetDir), "-p",
				"fileEncoding=".concat(this.encoding)
				});

are in a GraphAdapterGenerator class.
The GraphAdapterGenerator.jave and LanguageGenerator.mwe2 files are placed in the same plugin.

I don't understand why Mwe2Launcher can't find the workflow.
