Description

This Haskell script defines a library of parser combinators, and is taken from sections 1-6 of our article "Monadic Parser Combinators". Some changes to the library have been made in the move from Gofer to Haskell:

  • Do notation is used in place of monad comprehension notation;
  • The parser datatype is defined using "newtype", to avoid the overhead of tagging and untagging parsers with the P constructor.
