Description

I am building a wheel for a python package using setuptools and it seems that the naming of my wheel file is not respecting the PEP 491 convention.

For external reasons, I need to name my package with the structure {namespace}.{package-name}. If I follow the convention, I would expect that my wheel file is named: namespace_package_name-0.1.0-py2.py3-none-any.whl.

However, I get this name for my wheel: namespace.package_name-0.1.0-py2.py3-none-any.whl, which is not respecting the convention.

Expected behavior

I expect the "." in the package name to be replaced with a "_" in the wheel name.

How to Reproduce

1. create a hello_world package structure:

   hello_world
   |- my_package
   |    |- __init__.py
   |    |- hello_world.py
   |- pyproject.toml
   |- setup.cfg
   

2. in setup.cfg, write:

   [metadata]
   name = namespace.my-package
   version = 0.1.0
   
   [options]
   zip_safe = False
   include_package_data = True
   packages = find:
   

3. in project.toml, write:

   [build-system]
   requires = ["setuptools==66.0.0", "wheel"]
   build-backend = "setuptools.build_meta"
   

4. run pipx run build at the root of your hello_world package
5. inspect the dist directory which was created

Output

in the dist folder, you find:

• namespace.my_package-0.1.0-py3-none-any.whl
