I’m trying to generate a Python module with information provided from the pip install command. I have project with the following structure:

top_repository/
         |/setup.py
         |/requirements.txt
         |/my_proj
                |/__init__.py
                |/__main__.py
                |/_version.py
                |/conf.py

The setup.py is:

from setuptools import setup, find_packages
from distutils.util import convert_path

def get_requirements():
    with open('requirements.txt') as fp:
        return fp.read()

def get_version():
    st = {}
    version_file = convert_path('my_proj/_version.py')
    with open(version_file) as f:
        exec(f.read(), st)
    return st['_version']

setup(name='my_proj',
      version=get_version(),
      description='My Proj',
      packages=find_packages(),
      zip_safe=False)

Then, I create the wheel with python setup.py bdist_wheel

I’m looking for a way to get an argument from a pip option and add the argument (say --cfg_dir) to the conf.py file during the wheel installation. For instance, if I run:

$ pip install my_proj-0.0.1-py3-none-any.whl --target /usr/alternate/site-packages --cfg_dir /path/to/cfg_dir

Pip/setuptools will update the conf.py with:

CONF_DIR="/path/to/cfg_dir"

I’m using Python 3.9.18 and setuptools 53.0;0

I appreciate any help! Thanks in advance.

At this point, I have been searching around without any good pointers.
