Add missing __version__ attribute about crc HOT 2 CLOSED

Hi Jérémie,

thank you for your appreciation and feedback.

Let me quickly explain why I did remove the __version__ field.

From my point of view, it is a important to have a single source of truth for the package
metadata, like the version. Otherwise one may end up creating a release where the version shown by the package manager (pip) differs from the version reported by the package (__version__).

For sure there are solutions to this problem, like using pyproject.toml as the
single source of truth and adding some automated checks/updates. Still the margin
for error and the effort of maintanance increases.

Additionaly starting with python 3.8 a new mechansim to access package metadata was introduced.
Using this new mechanism you may be able to addresses your issue (see code snippet below),
if not please let me know.

>>> from importlib import metadata
>>> metadata.version('crc')
'3.0.0'

Hello Nicola,

Thanks for your detailed answer. I understand your point concerning properly maintaining the single source for the version number. To be honest, I never even thought about it before...
I was not aware of the relatively new metadata mechanism and will try it out. It won't completely solve my portability issue in all cases, but anyway, it is more of an inconvenience than a real issue!
I will close this issue.
