X-Description: LALR(k) parser generator
 Frown is an LALR(k) parser generator for Haskell 98 written in Haskell 98.
 .
 Its salient features are:
    -  The generated parsers are time and space efficient. On the downside, the
       parsers are quite large.
    -  Frown generates four different types of parsers. as a common
       characteristic, the parsers are genuinely functional (ie ‘table-free’);
       the states of the underlying LR automaton are encoded as mutually
       recursive functions. Three output formats use a typed stack
       representation, and one format due to Ross Paterson (code=stackless)
       works even without a stack.
    -  Encoding states as functions means that each state can be treated
       individually as opposed to a table-driven approach, which necessitates a
       uniform treatment of states. For instance, look-ahead is only used when
       necessary to resolve conflicts.
    -  Frown comes with debugging and tracing facilities; the standard output
       format due to Doaitse Swierstra (code=standard) may be useful for
       teaching LR parsing.
    -  Common grammatical patterns such as repetition of symbols can be
       captured using rule schemata. There are several predefined rule
       schemata.
    -  Terminal symbols are arbitrary variable-free Haskell patterns or guards.
       Both terminal and nonterminal symbols may have an arbitrary number of
       synthesized attributes.
    -  Frown comes with extensive documentation; several example grammars are
       included. Furthermore, Frown supports the use of monadic lexers, monadic
       semantic actions, precedences, and associativity, the generation of
       backtracking parsers, multiple start symbols, error reporting, and a
       weak form of error correction.
