Required packages for documentation build only listed in nox [docs] session

[mchaaler]

Move (or duplicate?) list of packages needed to build mkdocs-gallery documentation from noxfile.py (MKDOCS_GALLERY_EXAMPLES_REQS list) to setup.cfg as optional dependencies?

Refer to https://setuptools.pypa.io/en/latest/userguide/dependency_management.html#optional-dependencies.

For example:

[options.extras_require]
docs =
    matplotlib,
    seaborn,
    statsmodels,
    plotly,
    # memory_profiler,
    pillow  # PIL, required for image rescaling

Thus, the following command can be used to install these dependencies in the current Python virtual env:
pip install -e .[docs]

This can be useful for debugging puposes, when one needs to run mkdocs build without using nox.

I am not against it, but I am not sure that my nox_utils tool would know which ones to install with conda and which ones to install with pip...

An alternative is to provide requirements files in a folder named requirements:

• requirements_doc.txt and requirements_doc_conda.txt
• requirements_tests.txt and requirements_doc_conda.txt
• etc.

Users not wishing to use conda can install all requirements files with pip.
Would that be something ok for you ?

Note that personally I use PyCharm, and I simply tell PyCharm to use the python.exe created by nox in the .nox/doc/ folder. So I debug using the exact same session that nox uses.

Note: there is already a flake8_requirements.txt in ci_tools/ and a nox_requirements.txt at the root (this one should remain at the root)

No problem, I was just asking. I find the possibility to install extra dependencies by specifying a [keyword] to pip install rather elegant and was wondering if it was something that could be applied to mkdocs-gallery.

Why do you need some packages to be installed by conda, and the others by pip? Why not everything through pip? I usually consider that 'if it works with pip, it should work with conda as well'...

Understood. That's clever and might be useful sometimes.

It's just that I like to be able to do everything in the conda virtual environment I create when I start a project (no need to switch between environments in PyCharm, whether I want to build the docs, run the tests or check the CLI).
