  • bparser - parser for classical B (more information in
  • prologlib - library to construct and manipulate well-formed prolog terms
  • parserbase - library for uniform access to the formal language parsers (e.g. to embed a language into ltl)

  • answerparser - parser to read answers from the ProB prolog core (deprecated!)
  • unicode - lexer that transforms Event-B expressions and predicates from ASCII to Unicode syntax and vice3 versa (note: this is not extensible!)
  • cliparser - glue code for embedding the parser in the prolog core (deprecated!)
