The BNF Converter (bnfc) is a compiler construction tool generating a compiler front-end from a Labelled BNF grammar. It is currently able to generate C, C++, C#, Haskell, Java, and OCaml, as well as XML representations.

Given a Labelled BNF grammar the tool produces:

• an abstract syntax implementation
• a case skeleton for the abstract syntax in the same language
• an Alex, JLex, or Flex lexer generator file
• a Happy, CUP, or Bison parser generator file
• a pretty-printer as a Haskell/Java/C++/C module
• a Latex file containing a readable specification of the language
