How to generate this setup.py for a namespace subpackage?

Question

Hi!

I’m moving all my projects to Poetry and have issues with some of them. Namely, it’s packages that are subpackages to a bigger project.

Here is one example: https://github.com/foliant-docs/foliantcontrib.bump. It’s an extension for https://github.com/foliant-docs/foliant.

It means that during installation, the file foliant/cli/bump.py should be placed in foliant/cli folder in Foliant installation. To accomplish this, I’m using namespace package in setup.py.

I haven’t found a way to achieve the same thing with Poetry. Tried using packages in pyproject.toml, but that gives me a package name cli, not foliant.cli.

Your pyproject.toml link leads to a 404. How did you use packages?

I’ve been able to use namespace packages in Poetry just fine, but my use case is slightly different. I don’t have projects that share innermost (leaf) packages, so I’m not sure if this will work for you.

I have two projects, foo-project and bar-project:

foo-project
├── pyproject.toml
└── root_namespace
    └── nested_namespace
        └── subpackage_a
        │   └── __init__.py
        └── subpackage_b
            └── __init__.py

bar-project
├── pyproject.toml
└── root_namespace
    └── nested_namespace
        └── subpackage_c
            └── __init__.py

This is how I use packages in each pyproject.toml:

[tool.poetry]
...
packages = [{ include = "root_namespace" }]
...

This picks up root_namespace and the subpackages in the generated setup.py.

foo-project/setup.py:

packages = \
['root_namespace',
 'root_namespace.nested_namespace.subpackage_a',
 'root_namespace.nested_namespace.subpackage_b']

bar-project/setup.py:

packages = \
['root_namespace',
 'root_namespace.nested_namespace.subpackage_c']

Installing both places the files in the correct directories.

@moigagoo I’m not understanding how your project doesn’t follow the PEP420 guidelines. Is it because you don’t have and __init__.py https://github.com/foliant-docs/foliantcontrib.bump/tree/develop/foliant/cli
