Description of changes

Background

parsedmarc is both a Python module and CLI application which uses the module. Packaging of the Python module is currently broken by an unmet dependency. Packaging of the CLI application worked around this without correcting the broken module.

Proposed change

Instead of managing the module’s dependencies in the application’s package, manage them in the module’s package. This will allow both the module and application to be usable.

Before:

• pkgs.python3Packages.parsedmarc module, broken by unmanaged dependencies
• pkgs.parsedmarc application
  • Management of the module’s dependencies, via override

After:

• pkgs.python3Packages.parsedmarc module
  • Management of the module’s dependencies
• pkgs.parsedmarc application

Example

test_application() {
  nix-shell \
    --packages 'parsedmarc' \
    --run 'env --unset PYTHONPATH parsedmarc --version'
}

test_module() {
  nix-shell \
    --packages 'python3Packages.parsedmarc' \
    --run "python -c 'import parsedmarc; print(parsedmarc.email.policy.default)'"
}

Before:

$ test_module
error: Package ‘python3.12-parsedmarc-8.12.0’ in …/pkgs/development/python-modules/parsedmarc/default.nix:103 is marked as broken, refusing to evaluate.
$ test_application
8.12.0

After:

$ test_module
EmailPolicy()
$ test_application
8.12.0
