Path.Internal

Description

Internal types and functions.

Synopsis

Documentation

newtype Path b t Source #

Path of some base and type.

The type variables are:

  • b — base, the base location of the path; absolute or relative.
  • t — type, whether file or directory.

Internally is a string. The string can be of two formats only:

  1. File format: file.txt, foo/bar.txt, /foo/bar.txt
  2. Directory format: foo/, /foo/bar/

All directories end in a trailing separator. There are no duplicate path separators //, no .., no ./, no ~/, etc.

Constructors

hasParentDir :: FilePath -> Bool Source #

Helper function: check if the filepath has any parent directories in it. This handles the logic of checking for different path separators on Windows.

relRootFP :: FilePath Source #

Normalized file path representation for the relative path root

toFilePath :: Path b t -> FilePath Source #

Convert to a FilePath type.

All directories have a trailing slash, so if you want no trailing slash, you can use dropTrailingPathSeparator from the filepath package.
