how to override and bind ImportUriResolver [message #1736617]

I would like to implement different (in house) resolution protocols for the URIs used by the ImportUriGlobalScopeProvider.

I overrided ImportUriGlobalScopeProvider and bound it in my RuntimeModule. However, I do not see how to provide a custom ImportUriResolver to my custom ImportUriGlobalScopeProvider.

thanks in advance for your help

adding a simple binding does not work ?

public Class<? extends ImportUriResolver> bindImportUriResolver() {
return MyImportUriResolver.class;
}

Hi, thanks for your help,

Do you mean in the RuntimeModule? If so, there is no method bindImportUriResolver in the superclasses of "AbstractMyDslruntimeModule"

there does not need to be a superclass method

you can add a

public Class<? extends IYourService> bindIYourService() {
return YourServiceImpl.class;
}

as well.

see the docs on the conventions https://www.eclipse.org/Xtext/documentation/302_configuration.html#dependency-injection

Hi,

I had a similar problem and resolved it in accordance to the advice above.

It works great in the generated editor, but it looks like MyImportUriResolver is not invoked when parsing is done in tests. My guess is that something is still missing in injection. Would you please advise what should I look for?

Thank you,
Serge

where did you add the binding and what do you do in your tests? can you share a reproducable example

p.s.: and no MyImportUriResolver will not magically feed the resourceset. you have to add all resources to the resourceset yourself when standalone

Hi Christian,
I have create a minimalist project to demonstrate the failing test. Please find it attached with this message.
Thank you,

YOur uri converters makes limited sense in a standalone app.

@InjectWith(MyDslInjectorProvider)
class MyDslParsingTest{

	@Inject
	ParseHelper<Model> parseHelper
	@Test 
	def void loadModel() {
		new StandaloneSetup().platformUri = ".."
		URIConverter.URI_MAP.put(URI.createURI("platform:/plugin/org.xtext.example.mydsl/"), URI.createURI("platform:/resource/org.xtext.example.mydsl/"))
		val result = parseHelper.parse('''
           import my1

           usage AAAAA
		''')
		Assert.assertNotNull(result)
		Assert.assertEquals((result.usages.get(0) as Usage).name.name, "AAAAA")
	}
}

Thanks a lot!

I also mark question on StackOverflow http://stackoverflow.com/questions/37440304/predefined-definitions-in-xtext-script with reference to this page.
Thank you again,

Hi Christian,

Implementation based on ImportUriResolver you helped to resolve works just great in Xtext editor.

I am able to parse and retrieve entities resided in script file and also all referenced entities. Would you please advise how it is possible to retrieve entities resided in 'included' file, but not referenced in the script itself.

For example, in previous example:

           import my1
           usage AAAAA

due to the referencing, AAAAA is appears in parsed Model, but similar un-referenced entity (BBBBB) is not not a part of parsed model.
I am retrieving the model by the following code:

            IXtextDocument xtextDocument = editor.getDocument();
            
            Model model = xtextDocument.readOnly(new IUnitOfWork<Model, XtextResource>() {
                @Override
                public Model exec(XtextResource state) throws Exception {
                    EList<EObject> list = state.getContents();
                    if (list != null && list.size() != 0) {
                        return (Model) state.getContents().get(0);
                    }
                    return null;
                }
            });

Would you please advise what is the proper mechanism to retrieve the whole parsed content? Same question in relation to standalone parsing.

Thank you,
Serge

I don't understand this question. The resource contains only the stuff it contains.
You can follow references to other resources.

Thus you have to read the included file explicitly

Will it be possible to 'merge' both result models for both script files?
