API REFERENCE

\fIpathtools.path\fP

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.

\fIpathtools.patterns\fP

module

pathtools.patterns

synopsis

Wildcard pattern matching and filtering functions for paths.

author

Yesudeep Mangalapilly <[email protected]>

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 \(gaset(['*.py'])\(ga 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
