One other question. I have a rule where there is an ambiguity between one alternative in a block and the exit of the block. I'd like to try and use syntactic predicates to avoid this situation. I understand how to use syntactic predicates to control choice of alternatives within a rule. How can you use them when one of the choices is an exit from a rule?!? I tried moving the syntactic predicate up one level in the grammar, but I still get non-deterministic warnings in the original rule.
I saw this in the ANTLR documentation:
a
: (A (P)*) => A (P)*
| A
;
This was pretty close to what I have, but it didn't seem to make a difference.
Any suggestions?
