The pathtype package
This module provides type-safe access to filepath manipulations.
It is designed to be imported instead of System.FilePath and System.Directory and is intended to provide versions of functions from those modules which have equivalent functionality but are more typesafe.
The heart of this module is the Path ar fd abstract type which represents file and directory paths. The idea is that there are two phantom type parameters - the first should be Abs or Rel, and the second File or Dir. A number of type synonyms are provided for common types:
type AbsFile = Path Abs File type RelFile = Path Rel File type AbsDir = Path Abs Dir type RelDir = Path Rel Dir type RelPath fd = Path Rel fd type DirPath ar = Path ar Dir
The type of the combine (aka </>) function gives the idea:
(</>) :: DirPath ar -> RelPath fd -> Path ar fd
Together this enables us to give more meaningful types to a lot of the functions, and (hopefully) catch a bunch more errors at compile time.
The basic API (and properties satisfied) are heavily influenced by Neil Mitchell's System.FilePath module.
