NAME

pathtools - pathtools Documentation

Python API library for common path and pattern functionality.

EASY INSTALLATION

You can use pip to install pathtools quickly and easily:

$ pip install pathtools

API REFERENCE

pathtools.path

module

pathtools.path

synopsis

Directory walking, listing, and path sanitizing functions.

author

Functions

pathtools.path.get_dir_walker(recursive, topdown=True,
followlinks=False)

Returns a recursive or a non-recursive directory walker.
Parameters

recursive -- True produces a recursive walker; False produces a non-recursive walker.

Returns

A walker function.

pathtools.path.walk(dir_pathname, recursive=True, topdown=True,
followlinks=False)

Walks a directory tree optionally recursively. Works exactly like os.walk() only adding the recursive argument.
Parameters

	•		dir_pathname -- The directory to traverse.
	•		recursive -- True for walking recursively through the directory tree; False otherwise.
	•		topdown -- Please see the documentation for os.walk()
	•		followlinks -- Please see the documentation for os.walk()

pathtools.path.listdir(dir_pathname, recursive=True, topdown=True,
followlinks=False)

Enlists all items using their absolute paths in a directory, optionally recursively.
Parameters

	•		dir_pathname -- The directory to traverse.
	•		recursive -- True for walking recursively through the directory tree; False otherwise.
	•		topdown -- Please see the documentation for os.walk()
	•		followlinks -- Please see the documentation for os.walk()

pathtools.path.list_directories(dir_pathname, recursive=True,
topdown=True, followlinks=False)

Enlists all the directories using their absolute paths within the specified directory, optionally recursively.
Parameters

	•		dir_pathname -- The directory to traverse.
	•		recursive -- True for walking recursively through the directory tree; False otherwise.
	•		topdown -- Please see the documentation for os.walk()
	•		followlinks -- Please see the documentation for os.walk()

pathtools.path.list_files(dir_pathname, recursive=True, topdown=True,
followlinks=False)

Enlists all the files using their absolute paths within the specified directory, optionally recursively.
Parameters

	•		dir_pathname -- The directory to traverse.
	•		recursive -- True for walking recursively through the directory tree; False otherwise.
	•		topdown -- Please see the documentation for os.walk()
	•		followlinks -- Please see the documentation for os.walk()

pathtools.path.absolute_path(path)

Returns the absolute path for the given path and normalizes the path.
Parameters

path -- Path for which the absolute normalized path will be found.

Returns

Absolute normalized path.

pathtools.path.real_absolute_path(path)

Returns the real absolute normalized path for the given path.
Parameters

path -- Path for which the real absolute normalized path will be found.

Returns

Real absolute normalized path.

pathtools.path.parent_dir_path(path)

Returns the parent directory path.
Parameters

path -- Path for which the parent directory will be obtained.

Returns

Parent directory path.

pathtools.patterns

module

pathtools.patterns

synopsis

Wildcard pattern matching and filtering functions for paths.

author

Yesudeep Mangalapilly < yesudeep@gmail.com >

Functions

pathtools.patterns.match_path(pathname, included_patterns=None,
excluded_patterns=None, case_sensitive=True)

Matches a pathname against a set of acceptable and ignored patterns.
Parameters

	•		pathname -- A pathname which will be matched against a pattern.
	•		included_patterns -- Allow filenames matching wildcard patterns specified in this list. If no pattern is specified, the function treats the pathname as a match_path.
	•		excluded_patterns -- Ignores filenames matching wildcard patterns specified in this list. If no pattern is specified, the function treats the pathname as a match_path.
	•		case_sensitive -- True if matching should be case-sensitive; False otherwise.

Returns

True if the pathname matches; False otherwise.

Raises

ValueError if included patterns and excluded patterns contain the same pattern.

Doctests::

>>> match_path("/Users/gorakhargosh/foobar.py")
True
>>> match_path("/Users/gorakhargosh/foobar.py", case_sensitive=False)
True
>>> match_path("/users/gorakhargosh/foobar.py", ["*.py"], ["*.PY"], True)
True
>>> match_path("/users/gorakhargosh/FOOBAR.PY", ["*.py"], ["*.PY"], True)
False
>>> match_path("/users/gorakhargosh/foobar/", ["*.py"], ["*.txt"], False)
False
>>> match_path("/users/gorakhargosh/FOOBAR.PY", ["*.py"], ["*.PY"], False)
Traceback (most recent call last):
...
ValueError: conflicting patterns `set(['*.py'])` included and excluded

pathtools.patterns.match_path_against(pathname, patterns,
case_sensitive=True)

Determines whether the pathname matches any of the given wildcard patterns, optionally ignoring the case of the pathname and patterns.
Parameters

	•		pathname -- A path name that will be matched against a wildcard pattern.
	•		patterns -- A list of wildcard patterns to match_path the filename against.
	•		case_sensitive -- True if the matching should be case-sensitive; False otherwise.

Returns

True if the pattern matches; False otherwise.

Doctests::

>>> match_path_against("/home/username/foobar/blah.py", ["*.py", "*.txt"], False)
True
>>> match_path_against("/home/username/foobar/blah.py", ["*.PY", "*.txt"], True)
False
>>> match_path_against("/home/username/foobar/blah.py", ["*.PY", "*.txt"], False)
True
>>> match_path_against("C:\windows\blah\BLAH.PY", ["*.py", "*.txt"], True)
False
>>> match_path_against("C:\windows\blah\BLAH.PY", ["*.py", "*.txt"], False)
True

pathtools.patterns.filter_paths(pathnames, included_patterns=None,
excluded_patterns=None, case_sensitive=True)

Filters from a set of paths based on acceptable patterns and ignorable patterns.
Parameters

	•		pathnames -- A list of path names that will be filtered based on matching and ignored patterns.
	•		included_patterns -- Allow filenames matching wildcard patterns specified in this list. If no pattern list is specified, ["*"] is used as the default pattern, which matches all files.
	•		excluded_patterns -- Ignores filenames matching wildcard patterns specified in this list. If no pattern list is specified, no files are ignored.
	•		case_sensitive -- True if matching should be case-sensitive; False otherwise.

Returns

A list of pathnames that matched the allowable patterns and passed through the ignored patterns.

Doctests::

>>> pathnames = set(["/users/gorakhargosh/foobar.py", "/var/cache/pdnsd.status", "/etc/pdnsd.conf", "/usr/local/bin/python"])
>>> set(filter_paths(pathnames)) == pathnames
True
>>> set(filter_paths(pathnames, case_sensitive=False)) == pathnames
True
>>> set(filter_paths(pathnames, ["*.py", "*.conf"], ["*.status"], case_sensitive=True)) == set(["/users/gorakhargosh/foobar.py", "/etc/pdnsd.conf"])
True
