Hi,

can you please be a bit more specific on what your main does and which which parmeters/contexts it should be invoked?

i still dont get this.

you have opened your test.mydsl file and edit it.
then you hit save.
and then the main should be called with no params?

If it is on save only have a look at IXtextEditorCallback

(Implement it in yourdsl.ui and add a binding to yourdsluimodule)

def void configureMySpecialCallback(com.google.inject.Binder
binder) {
binder.bind(IXtextEditorCallback).annotatedWith(Names. named( "MySpecialCallback")).to(
MySpecialCallback);
}

If it should be called during build as well call it from your generator is the easiest one
