Yacc Conflict Analyzer (YCA)

YCA is a tool which intends to assist developers using LALR parser generators like yacc with the analysis of shift/reduce- and reduce/reduce-conflicts. (Even for grammars without any conflicts YCA might be useful to browse through the grammar or through the states of the parser table).

YCA can be found at http://www-users.rwth-aachen.de/reiner.pesch/yca/yca.html
