Official release and versions on PyPI?

[vandalt]

Hi @fmartinache,

I was discussing with @kammerje about making the JWST kernel phase pipeline separate from his xara fork and use the main xara instead as a depency. One things that came up in discussion if that if the pipeline depends on xara, using the main branch directly could be a problem if there are breaking changes.

I was wondering if you had plans to tag versions and release an official xara package on PyPI? I would be happy to help with this if needed.

Thanks!

Hi @vandalt,

thanks for the question. I'd be happy to release an official package on PyPI... this is something that I've never done. Where would you recommend me to look online to learn how to this the right way?

I like this guide: https://packaging-guide.openastronomy.org/en/latest/index.html.

The main section about packaging is this one: https://packaging-guide.openastronomy.org/en/latest/releasing.html. It uses git tags to control versions (instead of manually specifying versions in the setup and init files), but most things (building and releasing with twine) should still apply if you prefer to manually specify versions.

If you go the route of scm (git) versioning, there are a few things to modify in setup.py, pyproject.toml and xara/__init__.py, but once the setup is done I find this approach really nice. A ctrl+f for "scm" in the package layout section should help you find all the bits that need to be modified. I could send a PR with the updated setup files if you want.
