Hi,

i am not sure if i can follow you. antlrWorks is a separate tool from eclipse (make sure you pick the 3,x version)
you can tell xtext to create a "pure" grammar for debug purposes as follows. (xtext 2.9.x)

		language = StandardLanguage {
			parserGenerator = {
				debugGrammar = true
			}
			name = "org.xtext.example.mydsl.MyDsl"
			fileExtensions = "mydsl"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
			}


this will produce a DebugInternalMyDsl.g you can use in antlrworks

There is also a railroad diagram view within Xtext Window>Show View...>Other...>Xtext>Xtext Syntax Graph.
It doesn't allow to inspect ambiguities, but OTOH it has a notation for unordered groups.

Do as Christian suggested. Enable the debug grammar and then use AntlrWorks to open the DebugInternal<MyLanguage>.g located in the src-gen folder.
