Thanks for the good work on integrating antlr with Ruby. When using antlr version 3.0 (May 17. 2007) with the above grammar, however, I get the following error:
error(10): internal error: group Ruby does not satisfy interface ANTLRCore: missing templates [lexerRuleRefAndListLabel]
Is there anything I can do about it other than implementing the missing functions myself ?
