Hi,

I am using IXtextEditorCallback in my code. Then onwards when I am creating a project in editor it is not asking dialog to add xtext nature. Could you please tell me what to do?

class JPLEditorOnSave implements IXtextEditorCallback {

override afterCreatePartControl(XtextEditor editor) {}

override afterSave(XtextEditor editor) {
val IWorkspace workspace= ResourcesPlugin.getWorkspace();
val IPath location= Path.fromOSString(editor.resource.rawLocation.toFile.getAbsolutePath());
val IFile ifile= workspace.getRoot().getFileForLocation(location);
GenerationHandler.jpl2binExec(ifile)
}

override afterSetInput(XtextEditor xtextEditor) {}

override beforeDispose(XtextEditor editor) {}

override beforeSetInput(XtextEditor xtextEditor) {}

override onValidateEditorInputState(XtextEditor editor) {
return true
}
}

Yes right. I am using the below code for disable it in ui module before.

override bindIXtextEditorCallback() {
JPLEditorOnSave
}

But how can I add xtext nature now?

class JPLEditorUiModule extends AbstractJPLEditorUiModule {
override configure(Binder binder) {
super.configure(binder);
binder.bind(String).annotatedWith(Names.named((XtextContentAssistProcessor.COMPLETION_AUTO_ACTIVATION_CHARS))).toInstance('>_');

No I mean : copy the logic from nature adding editor callback to your callback

I dont understand. You mean like this:

class JPLEditorOnSave implements IXtextEditorCallback {

override afterCreatePartControl(XtextEditor editor) {}

override afterSave(XtextEditor editor) {
val IWorkspace workspace= ResourcesPlugin.getWorkspace();
val IPath location= Path.fromOSString(editor.resource.rawLocation.toFile.getAbsolutePath());
val IFile ifile= workspace.getRoot().getFileForLocation(location);
GenerationHandler.jpl2binExec(ifile)
}

override afterSetInput(XtextEditor xtextEditor) {}

override beforeDispose(XtextEditor editor) {}

override beforeSetInput(XtextEditor xtextEditor) {}

override onValidateEditorInputState(XtextEditor editor) {
return true
}

public static class NullImpl implements IXtextEditorCallback {

override afterCreatePartControl(XtextEditor editor) {
}

override afterSave(XtextEditor editor) {
}

override afterSetInput(XtextEditor xtextEditor) {
}

override beforeDispose(XtextEditor editor) {
}

override beforeSetInput(XtextEditor xtextEditor) {
}

override onValidateEditorInputState(XtextEditor editor) {
return true
}
}
}

if you have a look at NatureAddingEditorCallback you will find these strange code :

public class NatureAddingEditorCallback extends IXtextEditorCallback.NullImpl {
	private static final String ADD_XTEXT_NATURE = "add_xtext_nature";
	@Inject
	private ToggleXtextNatureAction toggleNature;

	private @Inject DontAskAgainDialogs dialogs;

	@Override
	public void afterCreatePartControl(XtextEditor editor) {
		IResource resource = editor.getResource();
		if (resource != null && !toggleNature.hasNature(resource.getProject()) && resource.getProject().isAccessible()
				&& !resource.getProject().isHidden()) {
			String title = Messages.NatureAddingEditorCallback_MessageDialog_Title;
			String message = Messages.NatureAddingEditorCallback_MessageDialog_Msg0 + resource.getProject().getName()
					+ Messages.NatureAddingEditorCallback_MessageDialog_Msg1;
			boolean addNature = false;
			if (MessageDialogWithToggle.PROMPT.equals(dialogs.getUserDecision(ADD_XTEXT_NATURE))) {
				int userAnswer = dialogs.askUser(message, title, ADD_XTEXT_NATURE, editor.getEditorSite().getShell());
				if (userAnswer == IDialogConstants.YES_ID) {
					addNature = true;
				} else if (userAnswer == IDialogConstants.CANCEL_ID) {
					return;
				}
			} else if (MessageDialogWithToggle.ALWAYS.equals(dialogs.getUserDecision(ADD_XTEXT_NATURE))) {
				addNature = true;
			}
			if (addNature) {
				toggleNature.toggleNature(resource.getProject());
			}
		}
	}
}

this basically does 2 things

(1) ask the user
(2) add the nature

Ok. But I am not at all doing with NatureAddingEditorCallback anywhere? So I need to added that code in class JPLEditorOnSave implements IXtextEditorCallback?
