PyPI releases

[AlecThomson]

Hi @maaijke @gmloose ,

With the recent changes going into RMextract, will there be new releases onto PyPI? The last release is from 2021 it seems.

It may be neat to setup some CI/CD tools to automatically release new versions onto PyPI, if desired. I can help to get those implemented if that'd be useful.

That is definitely the intention, yes. I leave it to @maaijke to decide when she thinks it's the proper time to do so. Some extra hands to help with automation would be welcomed very much. I sometimes struggle to find the time 😄.

Yesy please make a new version @gmloose I understand that the master is used in Linc so it should be fine. I hope to start soon on a complete rewrite of RMextract I will contact you @AlecThomson when I am ready

OK, I've put it on the top of my to-do list.

EDIT: I now have a better understanding of dynamic versioning, am changing this comment completely.

We can use the GitHub action like pypi-publish to publish to PyPI automatically.

I've recently been using config like this (note this uses a poetry build, which won't apply here)

name: Python package
on:
  push:
    tags:
      - "v*.*.*"
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Build and publish to pypi
        uses: JRubics/poetry-publish@v2.0
        with:
          pypi_token: ${{ secrets.PYPI_TOKEN }}

Which triggers when a release with the tag "v*.*.*" is made.

Let me know what you think and I can start a PR :)

It looks like the best option will be to follow this guide: https://packaging.python.org/en/latest/guides/publishing-package-distribution-releases-using-github-actions-ci-cd-workflows/

I've done this in the past. Here are two examples to get you going; they take slightly different approaches:

• https://github.com/casacore/python-casacore/blob/master/.github/workflows/build_release.yml
• https://github.com/lofar-astron/PyBDSF/blob/master/.github/workflows/build_release.yml

Both use automatic versioning using setuptool_scm and cibuildwheel for building portable binary wheels.
