Of course, it might just be that I missed something in reading the docs, like the fact that rule attributes are reached as ruleName.$attribute, not just $attribute... although that only seems to be mentioned implicity, in an example... and it does generate some code that would appear to work if the code were in the rule function, rather than separated into a predicate function. So it's a confusing situation. -- Sam Barnett-Cormack List: http://www.antlr.org/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org/mailman/options/antlr-interest/your-email-address --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "il-antlr-interest" group.
