Module util

Yield all items in an iterable collection that are distinct.

Unlike when using sets for a similar effect, the original ordering of the items in the collection is preserved by this function.

>>> print list(distinct([1, 2, 1, 3, 4, 4]))
[1, 2, 3, 4]
>>> print list(distinct('foobar'))
['f', 'o', 'b', 'a', 'r']

Parameters:

• iterable - the iterable collection providing the data

Returns: iterator

the distinct items in the collection

Extended pathname pattern matching.

This function is similar to what is provided by the fnmatch module in the Python standard library, but:

• can match complete (relative or absolute) path names, and not just file names, and
• also supports a convenience pattern ("**") to match files at any directory level.

Examples:

>>> pathmatch('**.py', 'bar.py')
True
>>> pathmatch('**.py', 'foo/bar/baz.py')
True
>>> pathmatch('**.py', 'templates/index.html')
False

>>> pathmatch('**/templates/*.html', 'templates/index.html')
True
>>> pathmatch('**/templates/*.html', 'templates/foo/bar.html')
False

Parameters:

• pattern - the glob pattern
• filename - the path name of the file to match against

Returns: bool

True if the path name matches the pattern, False otherwise

Compute the relative path to one path from another.

>>> relpath('foo/bar.txt', '').replace(os.sep, '/')
'foo/bar.txt'
>>> relpath('foo/bar.txt', 'foo').replace(os.sep, '/')
'bar.txt'
>>> relpath('foo/bar.txt', 'baz').replace(os.sep, '/')
'../foo/bar.txt'

Returns: basestring

the relative path
