Accessing the resource set from other plugin [message #909104]

Hi All,

I kindly ask for a piece of advice on the best way to access my xtext resource set from code running in separate plugins. The use case is very simple, and I would guess also very common. I have created a launch configuration for my DSL and now I want to perform different actions where I need to access the xtext resources.

A naive implementation is to do use the standalone setup, i.e. something like this:

Injector injector = new MyDSLStandaloneSetup().createInjectorAndDoEMFRegistration();
MyDSL dsl = injector.getInstance(MyDSL.class);
dsl.resourceSet // Here is my resource set!

This works ok, but seems kind of stupid since the xtext editor is already running and I only need a way to access it. In addition it seems that running the standalone concurrently with the xtext editor is causing some strange errors.

So what is the best way to get hold of the resource set from the launch configuration?

Thanks,
Johan

Hi,

never call standalonesetup from withing eclipse!
why do you need guice at all?

you could make the activator of the up plugin visible from other projects
or come up with a guicified activator in your plugins yourself
(monkey see monkey do from the ui project)

Hi Christian,

Thanks for your quick answer. I had a hunch that using standalone from within was a bad idea (one could almost tell from the name:)

My problem is not so much making methods visible from one plugin to another as to how I can get hold of the resource set at all.

Q: How do I get my hands on the resource set in the case that the launch configuration is part of the xtext-dsl plugin?

Thanks,
Johan

Hi,

sorry i dont get ehat you want to do. what do you mean with this launch config thing.
and that do you mean with "the resourceset"
can you elaborate what you actually want to do.
e.g. something like http://christiandietrich.wordpress.com/2011/10/15/xtext-calling-the-generator-from-a-context-menu/

Sorry for the confusion. Your post is very close to what I want to do, with exception that I do not use xtend for my codegen. With "the resourceset" I mean what you get from the resourceSetProvider in your example ("ResourceSet rs = resourceSetProvider.get(project);")

In your blog post the "resourceSetProvider" is set through guice. Is that the way to do it or can it be done directly with a method call to dsl-plugin?

Thanks for your patience,
Johan
