How @Inject ParseHelper<> is supposed to work ? [message #902319]

Hi,

I've create a test using only one ParseHelper and it worked. But when I tryed to add two parsers, both points to same class (ParserHelp<Library>). They have different object Id numbers (at debug) but same fileExtension.

In my case Company model is being imported in Library DSL.

I couldn't find where and how ParseHelper is binded.

Could someone explain me?

thanks

class TestComponentTemplateLibraryParsing extends AbstractXtextCommonTest {

	@Inject
	 ParseHelper<Library> parserLibrary

	@Inject
	 ParseHelper<Company> parserOrg

Hi,

there is no binding.

you need an

@RunWith(typeof(XtextRunner))
@InjectWith(typeof(MyDslInjectorProvider))

at your class

Hi Christian,

I already have that in my common super class.

@InjectWith(typeof(LibraryDslInjectorProvider))
@RunWith(typeof(XtextRunner))

abstract class AbstractXtextCommonTest {
	
	protected static XtextResourceSet resourceSet

What I would like to know is why both parserLibrary and parserOrg is being filled with the same (ParserHelp<Library>). They have different object Id numbers (at debug) but same fileExtension.
When parsing the organization model I got a classcast exception.
:

@Inject
	 ParseHelper<Library> parserLibrary

	@Inject
	 ParseHelper<Company> parserOrg

@Test
	def void ensureComponentTemplateLibraryFileAreBeingParsed() {
		organization = parseTestFile("tests/data/my.organization", parserOrg)
		assertNotNull(organization)
		library2 = parseTestFile("tests/data/core.analysis.base.library", parserLibrary)
		assertNotNull(library2)
}

Hi the parse helper is language specific. There was a topic on that
some weeks ago.

Here is a patched parsehelper

public class ParseHelper2<T extends EObject> extends ParseHelper<T> {
	
	public T parse(InputStream in, URI uriToUse, Map<?, ?> options, ResourceSet resourceSet) {
		Resource resource = resourceSet.createResource(uriToUse);
		resourceSet.getResources().add(resource);
		try {
			resource.load(in, options);
			final T root = (T) (resource.getContents().isEmpty() ? null : resource.getContents().get(0));
			return root;
		} catch (IOException e) {
			throw new WrappedException(e);
		}
	}

}

humm, I've searched the forum for ParseHelper and could not find the topic you talked about.

So I can conclude that I must not use ParseHelper<Company> parserOrg and load the organization model resource using the same resourceset that I used in the ParseHelper<Library>. right ?

Hi,

Well I still in doubt about guice and this ParseHelper2. I don't need to bind the ParseHelper2 ?

I couldn't make it work with ParseHelper2 too... I mean, I can load the resource of main dsl but not its associated model.

I don't understand. In the workflow I have this:

    bean = StandaloneSetup {
            scanClassPath = true
            platformUri = "${runtimeProject}/.."

            registerGeneratedEPackage = "organization.en.organizationDsl.OrganizationDslPackage"
            registerGenModelFile = "platform:/resource/organization.en/src-gen/organization/en/OrganizationDsl.genmodel"
        }

At runtime I can refer to the organization models from library editor without problems.

But at test it seems that organization is not being registered. this part of ParseHelp2 do not work because there isn't a resource factory in the registry:

Resource resource = resourceSet.createResource(uriToUse);

So, how can I load both resources using same resourceset?

regards,

Cristiano

Mrke sure that both stand alone setups are called. (E.g. by changing
the injector provider or by calling do setup from within the test

Hi Christian,

Create a custom injector provider and calling all the DslStandaloneSetup.doSetup() method inside it was the solution.

Thanks again for the support !

cheers,

Cristiano
