Have tried using antlr.Tool's -traceParser flag? Is this for debugging or
error reporting? You can also set your debugger in that method and watch to
see what exception gets thrown.

Subject: [antlr-interest] Getting information on failed syntactic predicate?
Hi,
Is it possible to get some information on why a certain syntactic predicate
failed?
eg. If I have the following rule:
a:
(b)=> b
| c
and b does not match, is it possible to have the "reason" why b failed? This
would be the error message generated by:
a:
b
ideally.
Is this possible?
Thanks in advance!
Daniel Shane
