Parser generator from FSF, (mostly) compatible with Yacc
Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR GLR parser employing LALR1 parser tables. As an experimental feature, Bison can also generate IELR1 or canonical LR1 parser tables. Once you are proficient with Bison, you can use it to develop a wide range of language parsers, from those used in simple desk calculators to complex programming languages.
Bison is upward compatible with Yacc all properly-written Yacc grammars ought to work with Bison with no change. Anyone familiar with Yacc should be able to use Bison with little trouble. You need to be fluent in C or C++ programming in order to use Bison. Java is also supported as an experimental feature.
