cookiecutter / whichcraft

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

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.

whichcraft's Issues

Please release new package w/correct whichcraft.__version__

Hi :)

I know, 465d532 fixed the mismatch of whichcraft.__version__, but the https://pypi.org/project/whichcraft/0.6.0 release still contains the wrong __version__ = "0.5.3" line

And this breaks my custom generalized dependency checks that I do in most of my projects, so I need to do hacky workarounds for whichcraft as requirement ;)

Can you please quickly make a new 0.6.1 release or so?

BTW, in case you don't know it: There is https://pypi.org/project/setuptools-scm , a nice official https://www.pypa.io tool for automatically determining project versions based on Git tags and passing them to setup() by using a simple setup entry point, also offering the feature of additionally writing the version into a Python module for keeping everything automatically consistent. I use it in all my Python projects, and even in some non-Python projects :)

Kind regards,
Stefan

This part fails on empty string

whichcraft/whichcraft.py

Line 58 in 6120d85

if any(cmd.lower().endswith(ext.lower()) for ext in pathext):

split on string that usually ends with ";" will generate empty string as last item.

As every string can end with empty string, this will always return plain version, not suffixed one

Unicode characters in README.rst breaks compilation with python-3.6

I've locally patched the FreeBSD port of py-whichcraft to avoid a compilation problem with python-3.6.x:

=======================<phase: configure      >============================
===>   py36-whichcraft-0.5.2 depends on package: py36-setuptools>0 - found

Stop.

Looks like some unicode characters sneaked into README.rst. The patch is available here:

https://svnweb.freebsd.org/ports/head/devel/py-whichcraft/files/patch-README.rst?revision=481787&view=co

I'd just paste it into this report, but I doubt the subtleties of the whitespace changes would survive the process.
