Ratatosk

An SLR parser generator written in Gofer (a Haskell variant) by Torben AEgidius Mogensen <torbenm@diku.dk>. Ratatosk generates purely functional backtracking LR0 grammar parsers (also in Gofer).

Even though the sematic value of a production is a function of the attributes of its right-hand side (and thus apparently purely synthesised), inherited attributes are easily simulated by using higher-order functions.
