Unparse attoparsec

This library provides an interface to build programs that can be interpreted both as parsers and as printers.

This library essentially defines two types:

  • Parser :: * -> * -> *, a wrapper around attoparsec's own Parser :: * -> *;
  • Printer :: * -> * -> *, a type which does the inverse of a parser;

and a type class Attoparsec, instantiated by Parser and Printer, wrapping attoparsec's core operations (including lookaheads!).

Monadic and applicative composition can be used under a ForallF Monad p constraint (resp. ForallF Applicative p), meaning that for all types x, the type p x is an instance of Monad (resp. Applicative). These constraints are made possible thanks to the constraints package. The profunctor-monad package provides convenient ways to work with them (with or rebindable syntax).
