Terence Parr 01b5510be1 Exceptions now work on rules. If you specify at least one catch, then it overrides all catches that ANTLR generates. Otherwise, there would be no way to override the generic recognition exception clause. 2012-09-22 11:58:41 -07:00

Terence Parr c6fd897287 altered naming scheme for listeners/visitors 
* names changed. visit() -> visitX(). enter/exit() -> enter/exitX()
* capitalizing automatically now. rule s -> SContext not sContext
* no enter/exit method in generic rule context object if rule has alt labels, nor in interfaces.
* dup labels allowed in same rule
* label X or x illegal if rule x exists
