Does bless have a versionID that can be retrieved? #98

Closed WouterJD closed 1 year ago

Describe the solution you'd like Please support a __version__ so that the version of the used library can be printed in a logfile Of course any other option serving the purpose is OK.

Describe alternatives you've considered n/a.

Additional context print(bless.__version__) is helpfull when debugging

Rather than hardcoding the version number, which could introduce human error if the version number is not updated with each new iteration. Would something like this work for you?

from importlib.metadata import version
version("bless")  # outputs: 0.2.4

Hi @kevincar

Thanks for this option; it sure works: logfile.Write(s % ('bless', importlib_metadata_version("bless") ))

Do you have an explanation why this option works for numpy, but not the others?

       #logfile.Write(s % ('argparse',     importlib_metadata_version("argparse") ))
       #logfile.Write(s % ('binascii',     importlib_metadata_version("binascii") ))
       #logfile.Write(s % ('math',         importlib_metadata_version("math") ))
        logfile.Write(s % ('numpy',        importlib_metadata_version("numpy") ))
       #logfile.Write(s % ('os',           importlib_metadata_version("os") ))

PS. numpy.__version__ and version("numpy") both produce the same result (in my case 1.21.4). I do not have the python (environment) knowledge to understand where the values come from and/or whether they are fundamentally identical.

Google on "python _version" does not help me, still wondering why not all packages have a version, or should I use another package name since it's coming with some other module?

The version("<pkg_name>") should work for install packages via pip or conda into your current python environment. Modules such as os, math, argparse, etc are builtin modules that are part of the Python Standard Library, so you can roughly say that the version for os or math is the same as your current python version.

Closing this for now. Feel free to list ideas if this posted solution is not sufficient.
