  • #156: Re-wrote the handling of pattern matches for listdir, walk, and related methods, allowing the pattern to be a more complex object. This approach drastically simplifies the code and obviates the CaseInsensitivePattern and FastPath classes. Now the main Path class should be as performant as FastPath and case-insensitive matches can be readily constructed using the new path.matchers.CaseInsensitive class.


29 Sep 2018

  • #153: Skip intermittently failing performance test on Python 2.


28 Sep 2018

  • #130: Path.py now supports non-decodable filenames on Linux and Python 2, leveraging the backports.os package (as an optional dependency). Currently, only listdir is patched, but other os primitives may be patched similarly in the patch_for_linux_python2 function.
  • #141: For merge_tree, instead of relying on the deprecated distutils module, implement merge_tree explicitly. The update parameter is deprecated, instead superseded by a copy_function parameter and an only_newer wrapper for any copy function.


18 Sep 2018

  • #151: No longer use two techniques for splitting lines. Instead, unconditionally rely on io.open for universal newlines support and always use splitlines.


15 Sep 2018

  • #146: Rely on importlib_metadata instead of setuptools/pkg_resources to load the version of the module. Added tests ensuring a <100ms import time for the path module. This change adds an explicit dependency on the importlib_metadata package, but the project still supports copying of the path.py module without any dependencies.


04 Sep 2018

  • #143, #144: Add iglob method.
  • #142, #145: Rename tempdir to TempDir and declare it as part of __all__. Retain tempdir for compatibility for now.
  • #145: TempDir.__enter__ no longer returns the TempDir instance, but instead returns a Path instance, suitable for entering to change the current working directory.


26 Mar 2018

  • #136: Fixed test failures on BSD.
  • Refreshed package metadata.


11 Feb 2018

  • Drop support for Python 3.3.


11 Feb 2018

  • Renamed namebase to stem to match API of pathlib. Kept namebase as a deprecated alias for compatibility.

  • Added new with_suffix method, useful for renaming the extension on a Path:

    orig = Path('mydir/mypath.bat')
    renamed = orig.rename(orig.with_suffix('.cmd'))


29 Oct 2017

  • Packaging refresh and readme updates.


27 Aug 2017

  • #130: Removed surrogate_escape handler as it’s no longer used.


17 Apr 2017

  • #124: Fixed rmdir_p raising FileNotFoundError when directory does not exist on Windows.


16 Apr 2017

  • #115: Added a new performance-optimized implementation for listdir operations, optimizing listdir, walk, walkfiles, walkdirs, and fnmatch, presented as the FastPath class.

    Please direct feedback on this implementation to the ticket, especially if the performance benefits justify it replacing the default Path class.


16 Apr 2017

  • Symlink no longer requires the newlink parameter and will default to the basename of the target in the current working directory.


23 Jan 2017


02 Jan 2017

  • Once again as in 8.0 remove deprecated path.path.


02 Jan 2017

  • #121: Removed workaround for #61 added in 5.2. path.py now only supports file system paths that can be effectively decoded to text. It is the responsibility of the system implementer to ensure that filenames on the system are decodeable by sys.getfilesystemencoding().


19 Nov 2016

  • Drop support for Python 2.6 and 3.2 as integration dependencies (pip) no longer support these versions.


19 Nov 2016

  • Merge with latest skeleton, adding badges and test runs by default under tox instead of pytest-runner.
  • Documentation is no longer hosted with PyPI.


16 Apr 2016

  • #112: Update Travis CI usage to only deploy on Python 3.5.


08 Apr 2016

  • Refreshed project metadata based on jaraco’s project skeleton.
  • Releases are now automatically published via Travis-CI.
  • #111: More aggressively trap errors when importing pkg_resources.


04 Oct 2015

  • #105: By using unicode literals, avoid errors rendering the backslash in __get_owner_windows.


10 Sep 2015

  • #102: Reluctantly restored reference to path.path in __all__.


27 Aug 2015

  • #102: Restored path.path with a DeprecationWarning.


27 Aug 2015

Removed path.path. Clients must now refer to the canonical name, path.Path as introduced in 6.2.


23 Aug 2015

  • #88: Added support for resolving certain directories on a system to platform-friendly locations using the appdirs library. The Path.special method returns an SpecialResolver instance that will resolve a path in a scope (i.e. ‘site’ or ‘user’) and class (i.e. ‘config’, ‘cache’, ‘data’). For example, to create a config directory for “My App”:

    config_dir = Path.special("My App").user.config.makedirs_p()

    config_dir will exist in a user context and will be in a suitable platform-friendly location.

    As path.py does not currently have any dependencies, and to retain that expectation for a compatible upgrade path, appdirs must be installed to avoid an ImportError when invoking special.

  • #88: In order to support “multipath” results, where multiple paths are returned in a single, os.pathsep-separated string, a new class MultiPath now represents those special results. This functionality is experimental and may change. Feedback is invited.


23 Aug 2015

  • Re-release of 7.6.1 without unintended feature.


19 Aug 2015

  • #101: Supress error when path.py is not present as a distribution.


09 Aug 2015


02 Aug 2015

  • #97: __rdiv__ and __rtruediv__ are now defined.


12 Jul 2015

  • #93: chown now appears in docs and raises NotImplementedError if os.chown isn’t present.
  • #92: Added compatibility support for .samefile on platforms without os.samefile.


14 Apr 2015

  • #91: Releases now include a universal wheel.


29 Jan 2015

  • In chmod, added support for multiple symbolic masks (separated by commas).
  • In chmod, fixed issue in setting of symbolic mask with ‘=’ where unreferenced permissions were cleared.


22 Jan 2015

  • #23: Added support for symbolic masks to .chmod.


05 Oct 2014

  • The open method now uses io.open and supports all of the parameters to that function. open will always raise an OSError on failure, even on Python 2.
  • Updated write_text to support additional newline patterns.
  • The text method now always returns text (never bytes), and thus requires an encoding parameter be supplied if the default encoding is not sufficient to decode the content of the file.


27 Sep 2014

  • path class renamed to Path. The path name remains as an alias for compatibility.


27 Sep 2014

  • chown now accepts names in addition to numeric IDs.


22 Sep 2014

  • Drop support for Python 2.5. Python 2.6 or later required.
  • Installation now requires setuptools.


17 Sep 2014

  • Allow arbitrary callables to be passed to path.walk errors parameter. Enables workaround for issues such as #73 and #56.


12 Jun 2014

  • #61: path.listdir now decodes filenames from os.listdir when loading characters from a file. On Python 3, the behavior is unchanged. On Python 2, the behavior will now mimick that of Python 3, attempting to decode all filenames and paths using the encoding indicated by sys.getfilesystemencoding(), and escaping any undecodable characters using the ‘surrogateescape’ handler.


30 Jan 2014

  • #53: Added path.in_place for editing files in place.


08 Nov 2013

  • path.fnmatch now takes an optional parameter normcase and this parameter defaults to self.module.normcase (using case normalization most pertinent to the path object itself). Note that this change means that any paths using a custom ntpath module on non-Windows systems will have different fnmatch behavior. Before:

    # on Unix
    >>> p = path('Foo')
    >>> p.module = ntpath
    >>> p.fnmatch('foo')


    # on any OS
    >>> p = path('Foo')
    >>> p.module = ntpath
    >>> p.fnmatch('foo')

    To maintain the original behavior, either don’t define the ‘module’ for the path or supply explicit normcase function:

    >>> p.fnmatch('foo', normcase=os.path.normcase)
    # result always varies based on OS, same as fnmatch.fnmatch

    For most use-cases, the default behavior should remain the same.

  • Issue #50: Methods that accept patterns (listdir, files, dirs, walk, walkdirs, walkfiles, and fnmatch) will now use a normcase attribute if it is present on the pattern parameter. The path module now provides a CaseInsensitivePattern wrapper for strings suitable for creating case-insensitive patterns for those methods.


27 Oct 2013

  • Issue #44: _hash method would open files in text mode, producing invalid results on Windows. Now files are opened in binary mode, producing consistent results.
  • Issue #47: Documentation is dramatically improved with Intersphinx links to the Python os.path functions and documentation for all methods and properties.


02 Jul 2013


02 Jul 2013

  • open() now passes all positional and keyword arguments through to the underlying builtins.open call.


28 May 2013

  • Native Python 2 and Python 3 support without using 2to3 during the build process.


26 May 2013

  • Added a chunks() method to a allow quick iteration over pieces of a file at a given path.
  • Issue #28: Fix missing argument to samefile.
  • Initializer no longer enforces isinstance basestring for the source object. Now any object that supplies __unicode__ can be used by a path (except None). Clients that depend on a ValueError being raised for int and other non-string objects should trap these types internally.
  • Issue #30: chown no longer requires both uid and gid to be provided and will not mutate the ownership if nothing is provided.


07 May 2013


15 Apr 2013

  • Issue #20: relpath now supports a “start” parameter to match the signature of os.path.relpath.


15 Jan 2013

  • Minimum Python version is now 2.5.


15 Jan 2013

  • Issue #5: Implemented path.tempdir, which returns a path object which is a temporary directory and context manager for cleaning up the directory.

  • Issue #12: One can now construct path objects from a list of strings by simply using path.joinpath. For example:

    path.joinpath('a', 'b', 'c') # or


14 Jan 2013

  • Issue #7: Add the ability to do chaining of operations that formerly only returned None.
  • Issue #4: Raise a TypeError when constructed from None.
