Description Marius Brehler 2017-07-25 07:24:23 UTC

scandir() is a directory iteration function like os.listdir(), except that instead of returning a list of bare filenames, it yields DirEntry objects that include file type and stat information along with the name. Using scandir() increases the speed of os.walk() by 2-20 times (depending on the platform and file system) by avoiding unnecessary calls to os.stat() in most cases.

scandir has been included in the Python 3.5 standard library as os.scandir(), and the related performance improvements to os.walk() have also been included. However, to bump dev-python/pathlib2 to the newest version, this package is required for Python 2.7. and Python 3.4.

dev-python/scandir: new package.

A better directory iterator and faster os.walk().

scandir() is a directory iteration function like os.listdir(), except that
instead of returning a list of bare filenames, it yields DirEntry objects that
include file type and stat information along with the name. Using scandir()
increases the speed of os.walk() by 2-20 times (depending on the platform and
file system) by avoiding unnecessary calls to os.stat() in most cases.

Required by dev-python/pathlib2[python2_7,python3_4].
