Does anyone know of a YACC-like parse generator that allows regular
expressions in rules (i.e. iteration, optionality, disjunction, grouping,
etc.). I know that I can "emulate" these with left recursive rules, but
it's a bit of a pain and makes the definition very hard to debug/extend.


I plan to use lex for the lexical analyzer, so compatibility with lex or a
similar tool is important.


Any help would be greatly appreciated.


Thanks,
