A User's Guide to Ryacc (version 0.0): a Parser Generator for Regular Right Part Grammars

Ryacc is a parser generator similar to Yacc sup [1] that processes a regular right part grammar specification of a language. Ryacc augments the parsers it generates with extensive automatic error recovery. A Regular Right Part Grammar (RRPG) is a context free grammar extended to include regular expression notation. These parsers generators resort to artificial recursion to specify lists and optional language elements.
