whichcraft

That code in my care
That sly command-line stare
That strips my operating system bare
It's whichcraft

This package provides cross-platform cross-python shutil.which functionality.

Usage

On Linux, Mac, Windows for Python 2.7 or any of the maintained 3s:

>>> from whichcraft import which
>>> which('date')
'/bin/date'
>>> which('calendar')
'/bin/calendar'
>>> which('cookiecutter')
'/Users/pydanny/.envs/fun/bin/cookiecutter'
>>> which('a-made-up-name') is None
True

Notes

This is a shim of the shutil.which function that's designed to work across multiple versions of Python and inside of windows. The code for Python 2.x is based on Python 3 code that I extracted from source. I originally did this for Cookiecutter but pulled it out in order to reduce line count for that project.

Edgecase: Date function works perfectly on mac os and linux system, hence returns string. But is an in-built function in windows hence returns none as value when called in windows.
