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 Yesudeep Mangalapilly <yesudeep@gmail.com>
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
