When debugging grammar in ANTLRWorks, ANTLRWorks builds a nice tree without any “^”, “!” operators inside rules. Is it possible to access this tree whithout adding “^”, “!” operators to grammar source?
Since you didn’t define
^and!operators (or rewrite rules), you must mean the parse tree (not the AST). But, the answer is: no, that’s not possible. They are created internally in ANTLRWorks, there’s no (public) API to access this structure.
