Synopsis
Type-safe replacement for System.FilePath etc
Description

This package provides type-safe access to filepath manipulations.

System.Path is designed to be used instead of System.FilePath. (It is intended to provide versions of functions from that module which have equivalent functionality but are more typesafe). System.Path.Directory is a companion module providing a type-safe alternative to System.Directory.

The heart of this package is the Path ar fd abstract type which represents file and directory paths. The idea is that there are two 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 Path.AbsFile = Path Abs File
type Path.RelFile = Path Rel File
type Path.AbsDir  = Path Abs Dir
type Path.RelDir  = Path Rel Dir

type Path.Abs  fd = Path Abs fd
type Path.Rel  fd = Path Rel fd
type Path.File ar = Path ar File
type Path.Dir  ar = Path ar Dir

The type of the combine (aka </>) function gives the idea:

(</>) :: Path.Dir ar -> Path.Rel 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.

For more details see the README.md file.

Related packages:

  • filepath: The API of Neil Mitchell's System.FilePath module (and properties satisfied) heavily influenced our package.

  • path: Provides a wrapper type around FilePath and maps to functions from filepath package. This warrants consistency with filepath functions. Requires Template Haskell.

  • data-filepath: Requires Typeable and Template Haskell.
