+PEP 621 and Setuptools
+######################
+:date: 2022-04-28
+:summary: PEP 621 and Setuptools
+
+In the world of Python packaging, the trend is moving to using
+:code:`pyproject.toml` to store all of the package's metadata as well as
+settings for different tools. Until recently, this trend meant adding another
+tool like `Poetry <https://python-poetry.org/>`_, `Flit
+<https://flit.pypa.io/>`_ or `PDM <https://pdm.fming.dev/>`_ instead of using
+the regular Setuptools (and maybe `build
+<https://pypa-build.readthedocs.io/>`_).  But with Setuptools 61.0.0, you can
+still use Setuptools and have a modern Python package.
+
+Why?
+----
+
+- Avoid having a plethora of Python package managers installed. This is more
+  noticeable when some are wrappers or replacements of virtualenv and then you
+  need to insall them globally.
+
+- With Setuptools you keep close to the state of `PEP 621
+  <https://peps.python.org/pep-0621/>`_ and your :code:`pyproject.toml` generic
+
+Why not?
+--------
+
+- You still need to manage virtual environments manually.
+
+- You need a very recent version of Setuptools. At the time of writing this
+  post I didn't find a distribution that had a new enough version of Setuptools
+  pacakged.
+
+- You need a supported version of Python. Currently this means Python 3.7 or
+  later.
+
+- You can get very close with an equivalent :code:`setup.cfg` and get backwards
+  compatibility.
+
+How?
+----
+
+I created a `sample Python project
+<https://git.shore.co.il/nimrod/samplepyproject>`_ that has everything you need
+to get started. It's tested to make sure a valid and working package, that
+editable installation work, etc. You can skip directly to the `pyproject.toml
+<https://git.shore.co.il/nimrod/samplepyproject/-/blob/main/pyproject.toml>`_
+file.
+
+A few notes. The only part that's Setuptools specific is specifying the
+attribute for getting the version dynamically. You can specify the version
+explicitly and be totally generic. The other settings that can be set
+dynamically need to be read from other files which isn't great. I would like to
+see the description be an attribute like version so I can point it to the
+docstring like Flit does. For editable installations you still need a
+:code:`setup.py` file but it's a 2 line file that calls :code:`setup()`. You
+don't need a :code:`setup.cfg` file at all.
+
+Looking forward
+---------------
+
+I'm pretty sure that once PEP 621 is approved, other package managers will
+adapt and tool specific configuration will be dropped. Also, support for using
+:code:`pyproject.toml` in Setuptools will stop being experimental. I think that
+once that's done and the only difference will be the 2 lines specifying the
+build system we will see projects that want easier onboarding adopt Setuptools
+to avoid forcing more tools on users. Over time distributions will package
+newer versions of Setuptools and you will be able to have a working Python
+environment just with the distribution packages.
+
+Appendix - PEP 582
+------------------
+
+Another PEP that's yet to be approved is `PEP 582
+<https://peps.python.org/pep-0582/>`_. This propsal is for  a package directory
+that's local to a project (in the spirit of :code:`node_modules`). The reason I
+mention it here is that this removes the need for virtual environments (and
+thus the other major selling point for the different package managers). Now,
+while it's not been approved and there's no version of Python that supports it
+out of the box, we can mimic it with a little creative shell scripting:
+
+.. code:: shell
+
+   PYTHON_VERSION="$(python3 -c 'from sys import version_info as v; print(f"{v[0]}.{v[1]}")')"
+   export PYTHONPATH="$PWD/__pypackages__/$PYTHON_VERSION:${PYTHONPATH:-}"
+   export PATH="$PWD/__pypackages__/$PYTHON_VERSION/bin:$PATH"
+
+With the above snippet we point Python to load packages from the
+:code:`__pypackages__` directory and add the :code:`bin` directory to the
+:code:`PATH` so executables are available. Lastly to install packages in that
+location we run :code:`python3 -m pip install -t
+"__pypackages__/$PYTHON_VERSION" foo`. I use `direnv <https://direnv.net/>`_
+quite a lot and I have the following snippet in a few projects:
+
+.. code:: shell
+
+   PYTHON_VERSION="$(python3 -c 'from sys import version_info as v; print(f"{v[0]}.{v[1]}")')"
+   export PYTHONPATH="$PWD/__pypackages__/$PYTHON_VERSION:${PYTHONPATH:-}"
+   export PATH="$PWD/__pypackages__/$PYTHON_VERSION/bin:$PATH"
+   python3 -m pip install "__pypackages__/$PYTHON_VERSION" -e .
+
+This performs an editable installation of the package and all it dependencies,
+so from that moment on I'm set and I don't any other package manager or even a
+virtual environment.
