There are a number of small, but very handy features added in pathlib over the last python versions, so I want to be able to use those also on older python versions.

if You are used to :

.. code-block::

import pathlib

pathlib.Path('some_file').unlink(missing_ok=True)

You will have no luck on python 3.7 - because the "missing_ok" parameter was added in python3.8

Of course You can do :

.. code-block::

import pathlib

try:
    pathlib.Path('some_file').unlink()
except FileNotFoundError:
    pass

but that clutters the code unnecessarily. So just use :

.. code-block::

import pathlib3x as pathlib

and You can enjoy the latest pathlib features even on older python versions.

Some own extensions to that pathlib will be added probably over time. At the moment we added some wrappers to shutil like "copy", "rmtree", "copytree", so You can do :

.. code-block::

import pathlib3x as pathlib
my_file = pathlib.Path('/etc/hosts')
to_file = pathlib.Path('/tmp/foo')
my_file.copy(to_file)

If You have some nice features for pathlib, let me know - I will consider to integrate them.

Usage

just check out the latest python documentation : https://docs.python.org/3/library/pathlib.html and select 3.10 Branch

Additional Features are documented here :

PurePath.append_suffix(suffix) Return a new path with the suffix appended. If the original path doesn’t have a suffix, the new suffix is appended. If the original path have a suffix, the new suffix will be appended at the end. If suffix is an empty string the original Path will be returned.

.. code-block:: python

>>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
>>> p.append_suffix('.bz2')
PureWindowsPath('c:/Downloads/pathlib.tar.gz.bz2')
>>> p = PureWindowsPath('README')
>>> p.append_suffix('.txt')
PureWindowsPath('README.txt')
>>> p = PureWindowsPath('README.txt')
>>> p.append_suffix('')
PureWindowsPath('README.txt')

PurePath.is_path_instance(__obj) Return True if __obj is instance of the original pathlib.Path or pathlib3x.Path. Useful if You need to check for Path type, in an environment were You mix pathlib and pathlib3x

.. code-block:: python

>>> import pathlib3x
>>> import pathlib

>>> pathlib3x_path = pathlib3x.Path('some_path')  # this might happen in another module !
>>> pathlib_path = pathlib.Path('some_path')
>>> isinstance(pathlib3x_path, pathlib.Path)
False
>>> isinstance(pathlib_path, pathlib3x.Path)
False

# in such cases were You need to mix pathlib and pathlib3x in different modules, use:
>>> pathlib3x_path.Path.is_path_instance(pathlib3x_path)
True
>>> pathlib3x_path.Path.is_path_instance(pathlib_path)
True

PurePath.replace_parts(old, new, count=-1) Return a new Path with parts replaced. If the Original Path or old has no parts, the Original Path will be returned. On Windows, the replacement operation is not case sensitive, because of case folding on drives, directory and filenames. You can also replace absolute paths with relative paths what is quite handy - just be aware that the results might look unexpected, especially on Windows.

*old, new* can be pathlib.Path or Path-like objects

if the Original Path is resolved, You should probably also resolve *old* and *new* - because if symlinks are involved,
the results might be unexpected.

be aware of case folding in windows, the file "c:/Test/test.txt" is the same as "c:/test/Test.TXT"

.. code-block:: python

>>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
>>> p.replace_parts(PureWindowsPath('C:/downloads'), PureWindowsPath('D:/uploads'))
PureWindowsPath('D:/uploads/pathlib.tar.gz')

>>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
>>> p.replace_parts('C:/downloads','D:/uploads')
PureWindowsPath('D:/uploads/pathlib.tar.gz')

# handy to replace source directories with target directories on copy or move operations :
>>> source_dir = pathlib.Path('c:/source_dir')
>>> target_dir = pathlib.Path('c:/target_dir')
>>> source_files = source_dir.glob('**/*.txt')
>>> for source in source_files:
        target = source.replace_parts(source_dir, target_dir)
...     source.copy(target)

# this will always return PureWindowsPath(), because PureWindowsPath('.') has no parts to replace
>>> p = PureWindowsPath('.')
>>> p.replace_parts('.', 'test')
PureWindowsPath()

# looks unexpected but is correct, since PureWindowsPath('/uploads') is a relative path in Windows
>>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
>>> p.replace_parts('C:/downloads', '/uploads')
PureWindowsPath('uploads/pathlib.tar.gz')

# take care when replace, it might match on parts You are not aware of
>>> p = PureWindowsPath('c:/downloads/Downloads.tar.gz')
>>> p.replace_parts('downloads', 'uploads')
PureWindowsPath('c:/uploads/uploads.tar.gz')    # that was not intended !

# better
>>> p = PureWindowsPath('c:/downloads/Downloads.tar.gz')
>>> p.replace_parts('downloads', 'uploads', 1)
PureWindowsPath('c:/uploads/Downloads.tar.gz')

# much better
>>> p = PureWindowsPath('c:/downloads/Downloads.tar.gz')
>>> p.replace_parts('c:/downloads', 'c:/uploads')
PureWindowsPath('c:/uploads/Downloads.tar.gz')

shutil wrappers

Path.copy(target, follow_symlinks) wraps shutil.copy, see: https://docs.python.org/3/library/shutil.html

.. code-block:: python

>>> import pathlib3x as pathlib
>>> s = pathlib.Path('c:/Downloads/pathlib.tar.gz')
>>> t = pathlib.Path('c:/Downloads/pathlib.tar.gz.backup')
>>> s.copy(t)

Path.copy2(target, follow_symlinks=True) wraps shutil.copy2, see: https://docs.python.org/3/library/shutil.html

.. code-block:: python

>>> import pathlib3x as pathlib
>>> s = pathlib.Path('c:/Downloads/pathlib.tar.gz')
>>> t = pathlib.Path('c:/Downloads/pathlib.tar.gz.backup')
>>> s.copy2(t)

Path.copyfile(target, follow_symlinks) wraps shutil.copyfile, see: https://docs.python.org/3/library/shutil.html

.. code-block:: python

>>> import pathlib3x as pathlib
>>> s = pathlib.Path('c:/Downloads/pathlib.tar.gz')
>>> t = pathlib.Path('c:/Downloads/pathlib.tar.gz.backup')
>>> s.copyfile(t)

Path.copymode(target, follow_symlinks=True) wraps shutil.copymode, see: https://docs.python.org/3/library/shutil.html

.. code-block:: python

>>> import pathlib3x as pathlib
>>> s = pathlib.Path('c:/Downloads/pathlib.tar.gz')
>>> t = pathlib.Path('c:/Downloads/pathlib.tar.gz.backup')
>>> s.copymode(t)

Path.copystat(target, follow_symlinks=True) wraps shutil.copystat, see: https://docs.python.org/3/library/shutil.html

.. code-block:: python

>>> import pathlib3x as pathlib
>>> s = pathlib.Path('c:/Downloads/pathlib.tar.gz')
>>> t = pathlib.Path('c:/Downloads/pathlib.tar.gz.backup')
>>> s.copystat(t)

Path.copytree(target, symlinks=False, ignore=None, copy_function=copy2, ignore_dangling_symlinks=True, dirs_exists_ok=False) wraps shutil.copytree, see: https://docs.python.org/3/library/shutil.html

dirs_exists_ok=True will raise a TypeError on Python Versions < 3.8

.. code-block:: python

>>> import pathlib3x as pathlib
>>> s = pathlib.Path('c:/Downloads')
>>> t = pathlib.Path('c:/temp/Backups')
>>> s.copytree(t)

Path.rmtree(ignore_errors=False, onerror=None) wraps shutil.rmtree, see: https://docs.python.org/3/library/shutil.html

.. code-block:: python

>>> import pathlib3x as pathlib
>>> p = pathlib.Path('c:/Downloads/old')
>>> p.rmtree()

Caveats of pathlib3x

.. code-block:: python

>>> import pathlib3x
>>> import pathlib

>>> pathlib3x_path = pathlib3x.Path('some_path')  # this might happen in another module !
>>> pathlib_path = pathlib.Path('some_path')
>>> isinstance(pathlib3x_path, pathlib.Path)
False
>>> isinstance(pathlib_path, pathlib3x.Path)
False

# in such cases were You need to mix pathlib and pathlib3x in different modules, use:
>>> pathlib3x_path.Path.is_path_instance(pathlib3x_path)
True
>>> pathlib3x_path.Path.is_path_instance(pathlib_path)
True

So dont mix pathlib with pathlib3x and expect that objects are an instance of Pathlib and vice versa. This can happen easily if You have many Modules. Just keep it in mind !

Usage from Commandline

.. code-block::
