Terence Parr 8a34176d82 added listener unit tests. fixed bug that didn't create ctx getters properly for recursive rules. added Symbol extends Token to parse tree stuff. added visitTerminal to Visitor. recursive alts now track their original, unedited AltAST subtree so we can properly count rule refs etc... later. dup of RuleRefAST was making wrong node. don't gen dispatch methods if no listener. 2012-02-22 12:44:33 -08:00
Terence Parr 58ef729be5 renamed next to target. factored out to methods, commented code. 2012-02-21 12:47:34 -08:00

Terence Parr 71b75c88dd Fix regression; did not gen enter/exit in alt label structs. 2012-02-18 15:16:42 -08:00
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
