Hi all!
I need your help, I have this grammar:

Xasm:
	starts+=Asm|Model
	greetings+=Greeting*
;

Model:
	asyncr?='asyncr'? 'model' name=ID	
	
;


Asm:
	asyncr?='asyncr'? 'asm' name=ID
;

Greeting:
	'Hello' name=ID '!'
;

I create a file named "test.asm" like this:

asm name_class
Hello ciao!

How can I check in definitions of grammar if name_class is the same word of the name file (like in Java)?

Thank you,
Massimo

Hi,

you can ask any EObject (thus your Asm) for its eResource()
and the Resource for it's uri.
the uri contains the filename.

I'm sorry but i don't understand.
Can you link a manual where the EObject are explained?

Thank you

This is notwhere explained. Xtext reuses Ecore. for more information see http://download.eclipse.org/modeling/emf/emf/javadoc/2.7.0/org/eclipse/emf/ecore/package-summary.html

it is basically: object.eResource().getURI().trimFileExtension().lastSegment();
just wrap what into your check method.
