Yes - PRECC. Never used it myself - I went with PCCTS in the end, because
of the ease of building AST's, and the SORCERER utility. PRECC is a parser
generator only - you supply your own lexer (but flex works fine). It looks
to have similar power to PCCTS's ANTLR (infinite lookahead, good attribute
handling, etc). Also, the input to the parser generator is a literate
program, which makes some people very happy. Find out more from:
