Xtext-enabled TextArea [message #1080744]

Hi All,
I have a usecase where I will be providing my dsl in a textarea(SWT Text control) embedded into an Editor in my eclipse plug-in. I want to use Xtext's feature of Syntax Highlighting, validation, code completion etc.

Is there a way to do this ?

Regards,
Priya

Hi Christian,
I got the code pointed by you. There were some errors, when I tried to 'Generate Xtext Artifacts', the import rule was conflicting with some other rule. Then I changes the multiplicity of import from * to + , then it compiled fine.

Now I wonder, what the code is doing. I saw the example project, it has three dsl files. Can you please explain a little what the behavior is ? How should I know what the project is providing ?

When I open the .mql dsl, it has some methods and all, but my requirement is how can I make an swt textarea to be xtext-enabled ? I mean instead of using editor provided by xtext, I will enter my language into the textarea and the textare should provide me all the editor functionality(like syntax checking, code completion etc...). Is your project doing this ? If yes, could you please tell me the steps- how to test/use the functionality written into the plug-in ?

Regards,
Priya

Hi Christian,

I am able to create my own view(xtext-enabled) the same way it was done in your code.

Inside my grammar I am using FullJvmFormalParameter and JvmTypeReference types for my function argument and return types resp. For below method definition(language), the editor is not showing any error

function getXC(String xc): String {
return xc;
}
function getName(String a, java.util.ArrayList s)
: String {
if(a.equals('A')){
return a
}
else return "";
}

But I am getting error markers when I write the function inside my view "Couldn't resolve reference to JvmType 'String'.". Attaching the screen shoot for your reference.

Could you please tell, what am I missing here ?

Hi,

The question is: did you do the changes i do in the uimodule?
if not you need a physical java project you let the resource you edit point to respectively come from

Hi,

if the resource you edit physically comes from a java project and the resource you create is tied to this java project it should work out of the box (IResourceSetProvider)

For editor I have the resource tied to java project and it is working fine.

But how can I tie a view to java project ? The problem I am facing is in the view

Hi,

using a different version of org.eclipse.xtext.ui.editor.embedded.IEditedResourceProvider

e.g.

public class ModelQueryLanguageEditedResourceProvider implements IEditedResourceProvider {

	@Inject
	IResourceSetProvider rsp;
	
	private IProject project;

	public IProject getProject() {
		return project;
	}

	public void setProject(IProject project) {
		this.project = project;
	}

	public XtextResource createResource() {
		return (XtextResource) rsp.get(project).createResource(URI.createURI("platform./resource/"+project.getname()+"/test.mql"));
	}

}

P.S: are you sure it dosent work with

public class ModelQueryLanguageEditedResourceProvider implements IEditedResourceProvider {

	@Inject
	IResourceSetProvider rsp;
	
	private IProject project;

	public IProject getProject() {
		return project;
	}

	public void setProject(IProject project) {
		this.project = project;
	}

	public XtextResource createResource() {
		return (XtextResource) rsp.get(project).createResource(URI.createURI("test.mql"));
	}

}

simply call setProject on the ModelQueryLanguageEditedResourceProvider
you pass to the embeddedEditorFactory
