Hello,

I would like to create Xtext projects (base + ui) programmatically.
I took a look at xtext project wizard but I cannot figure out which methods of which classes have to be used.

Do someone already had the same need and could provide me with an implementation example ?

Thanks

Is there a way to update the resource description manually? At the moment only when I save the computeExportedObjects() method is called. So unsaved elements are not covered by xtext then.

Which method is necessary to call to update the resource description?

	public class EditorCallback extends NatureAddingEditorCallback {
	@Override
	public void afterSave(XtextEditor editor) {
		System.out.println("here we go");
		editor.getDocument().modify(new IUnitOfWork<Void, XtextResource>() {
          
			@Override
			public java.lang.Void exec(XtextResource state) throws Exception {
				ContentModel mymodel = ((ContentModel) state.getContents().get(0));
				System.out.println(mymodel);
				mymodel.setName(mymodel.getDisplayName().toString());
				
				return null;
				
			}

Topic: Using a File located in workspace during Validation process

Using a File located in workspace during Validation process [message #1060591]

Hello

I have a little question I couldn't solve so far.
I'm using ETL and EVL to perform a transformation on my generated model from Xtext. I use them as standalone through a call in the validation process from the embedded Eclipse workspace.

In order to work, both ETL and EVL needs to be provided a "File" instance of a file located on a folder of the "Xtext Eclipse".

I use the "platform:" URI code to access file from the embedded Eclipse workspace.
How can I create a File instance of a file in my xtext.base folder, without having to provide the full path to the file ?

I know the issue might sound Epsilon-related rather then Xtext-related, but the problem is just about loading a file, from Xtext validation process, so I thought here would be a better place to get some help.

Thanks for your help.

Best reguards,

Christophe

generated launch configuration [message #1060497]

Hi

when running the mwe2 for the first time, Xtext also generates a launch
configuration with proper MaxPergGen arguments (to avoid out of memory
errors), in the (hidden by default) directory .launch, called "Launch
Runtime Eclipse.launch"

right-clicking on the project, Run As... shows "Eclipse Application" but
selecting this will NOT use the generated launch configuration (it
creates a new launch configuration, alas, without MaxPermGen
arguments)... one has to open the Run Configurations dialog in order to
use the generated launch configuration (and to know about that, since by
default .launch is hidden)...

is that the intended behavior?

cheers
Lorenzo

Hello, in case anyone else has an Xtext language which has references to Ecore classes (EClass) and wants to support EPackage import statements, may be this http://blog2.vorburger.ch/2013/05/xtext-dsl-with-epackage-namespace.html blog post of mine is of interest / use to some of you.

Hi,

as a more recent follow up of http://www.eclipse.org/forums/index.php/mv/msg/18749/60087/#msg_60087 I am interested in applying a stereotype to an xtext element.

Is there any progress here or any suggestions to do it with current versions?

I'd like to define elements in my dsl and use them from uml:

xtext:
MyElem returns my::mystereotype: 'MyElem' name=ID;

... and use/reference it in uml wherever my::mystereotype is expected. I can get it all working with "returns uml::class" instead of the stereotype, however I need to have stereotypes applied.

The link cited above is not of much help to me as further references there are broken urls.

thanks
dennis
