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('./foo/**.py', 'foo/bar/baz.py') True >>> pathmatch('./foo/**.py', 'bar/baz.py') False >>> pathmatch('^foo/**.py', 'foo/bar/baz.py') True >>> pathmatch('^foo/**.py', 'bar/baz.py') False >>> pathmatch('**/templates/*.html', 'templates/index.html') True >>> pathmatch('**/templates/*.html', 'templates/foo/bar.html') False :param pattern: the glob pattern :param filename: the path name of the file to match against z[^/]z[^/]/z[^/]+z[^/]+/z (?:.+/)*?z(?:.+/)*?[^/]+)?z?/*z*/z**/z**^rNz./z ([?*]+/?)$/) r enumerater8r<appendescaperjoinreplaceossep)rFrGsymbolsbufidxpartrrrr pathmatchs('  "rZc@seZdZedZdS) TextWrapperz((\s+|(?<=[\w\!\"\'\&\.\,\?])-{2,}(?=\w))N)__name__ __module__ __qualname__r8compile wordsep_rerrrrr[sr[FrLz list[str])textwidthinitial_indentsubsequent_indentr cCst|||dd}||S)aSimple wrapper around the ``textwrap.wrap`` function in the standard library.
