Path IO

This package provides an interface to the directory package for users of Chris Done’s path. It also implements some missing stuff like recursive scanning and copying of directories, working with temporary files/directories, etc.

Consult Haddocks for usage, which should be trivial.

Path IO 1.3.3

  • (Hopefully) fixed test suite failure with Cabal 2.0 and GHC 8.2.1.

Path IO 1.3.2

  • Reduce a number of (MonadIO m, MonadThrow m) constraints to just MonadIO m #27

Path IO 1.3.1

  • Made listDirRecur faster for deep directory trees.

Path IO 1.3.0

  • Change the default behavior of recursive traversal APIs to not follow symbolic links. The change affects the following functions: listDirRecur, copyDirRecur, and copyDirRecur'.

  • Add isSymlink which allows to test whether a path is a symbolic link.

  • Move the type functions AbsPath and RelPath to the AnyPath type class (previously they were standalone closed type families, now they are associated types of AnyPath).

  • Improved the documentation and metadata.

Path IO 1.2.3

  • Allowed time-1.7.

Path IO 1.2.2

  • Fixed a bug in setModificationTime function that previously called setAccessTime instead of setModificationTime from directory.

  • Added notes to all pieces of API that are conditional (some functions are only available if directory- or later is used, now it’s mentioned for every such function explicitely).

Path IO 1.2.1

  • Allowed directory-

  • Added getXdgDir. Only available of directory- or later is used.

  • Various cosmetic improvements.

Path IO 1.2.0

  • Added walkDir function to traverse a directory tree with a handler.

  • Added walkDirAccum function which is like walkDir but also accepts an output writer and returns the accumulated output.

  • All recursive traversal functions (existing and new) now safely handle directory loops due to symbolic or hard links.

  • Added “since” notes to public functions in API.

Path IO 1.1.0

  • Fixed bug in copyDirRecur when it was unable to fully copy read-only directories.

  • Added copyDirRecur' function that works just like copyDirRecur, but does not preserve directory permissions.

Path IO 1.0.1

  • Fixed bug in copyDirRecur for non-existing destination paths when directory to copy does not contain sub-directories.

  • Made copyDirRecur try to copy permissions for destination directory too (previously it only tried to copy them for sub-directories).

Path IO 1.0.0

  • Changed signature of getAppUserDataDir, so it takes String as the first argument.

  • Removed deprecated forgivingAbsence' function.

  • Made findFile lazier, it stops searching as soon as a file is found.

  • Added some tests.

Path IO 0.3.1

  • Introduced synonym for forgivingAbsence'ignoringAbsence. forgivingAbsence' is deprecated now, but it’s still there.

  • Added a handy shortcut ensureDir that is defined as ensureDir = createDirIfMissing True.

  • Made getHomeDir and getTempDir more robust when they are influenced by values of environment variables.

Path IO 0.3.0

  • Added forgivingAbsence, resolveFile, and resolveDir functions, so the package now provides all functionality that Path.IO module in Stack has.

  • Added closed type family RelPath, makeRelative, and makeRelativeToCurrentDir functions.

  • Fixed signature of getAppUserDataDir.

Path IO 0.2.0

  • Added functions from temporary: withTempFile, withTempDir, withSystemTempFile, withSystemTempDir, openTempFile, openBinaryTempFile, and createTempDir. temporary is a lightweight and ubiquitous package, so depending on it should be OK.

Path IO 0.1.1

  • Fixed type signatures of renameFile and copyFile.

Path IO 0.1.0

  • Initial release.
