Hello Guys,

i am working on a special grammar for xtext. AT the moment, i am trying to put "Cross Reference" within Quoatation Marks. The specific rule is:

GoStatement hidden(WS):
 gosub?='gosub' '"' sub=[Subroutine|ID] '"'
;

With this rule, i get the following error: missing EOF at 'gosub'

When i Change the " to for example @ everythign is working fine.
Can you tell me how i get it working with Quotation Marks?
Thanks!

AFAIK, you may have a conflict with the terminal rule STRING if you use the standard xtext terminals.
grammar de.ulrichmerkel.Umecode1 with org.eclipse.xtext.common.Terminals

"terminal" implies that the content between the quotes is not evaluated any further.
You may delete the "with ..." and specify your own version of terminals
where double quotes no longer specify a terminal STRING

Thank you very much for your answer Smile

The Problem is that the double Quotes should still imply String but just not in this specific rule ... Is that possible?

Hi Marc,
I think that's a question for someone who is much more experienced than I am right now.
But IIRC, there was a similar question in this forum recently. If you have a look at the last topics ..
