Add scikit-build-core

[matthewfeickert]

(Moving from scikit-build/scikit-build-core#1033)

@LecrisUT @henryiii Please have a member of the scikit-build-core team complete the missing items from the checklist to get started.

• Create an account on Anaconda Cloud
• Reply here with the link to your account (https://anaconda.org/henryiii)
• Make a new Anaconda Cloud API token with permissions described in https://scientific-python.org/specs/spec-0004/#process-for-adding-new-projects

• Save the API token as a repo GitHub Actions secret named ANACONDA_ORG_UPLOAD_TOKEN
• Direct @scientific-python/nightly-wheels-developers to a scikit-build-core nightly wheel for us to upload to create the package in the registry
• Verify that we have added you to the scikit-build-core team "Group" on https://anaconda.org/scientific-python-nightly-wheels
• Verify that we have added the package scientific-python-nightly-wheels/scikit-build-core to the scikit-build-core team "Group"

If you'd also like to use the scientific/upload-nightly-action GitHub Action please check out the action repo's README. If you need to collect wheels from different CI jobs, consider creating a new GitHub Actions workflow with logic similar to matplotlib's or Awkward's.

If you have any questions please just ask here!

Is that supposed to be an org account or a personal account? I've had an personal Anaconda account henryiii for 9 years and 5 months. :)

Good question: Personal account. So, https://anaconda.org/henryiii will work fine.

[matthewfeickert]

@henryiii I seeded the project (https://anaconda.org/scientific-python-nightly-wheels/scikit_build_core) with the latest wheel from PyPI and added you as an admin. So once you generate an API token you should be good to go for uploading nightly wheels. Please let us know here once you've done so (and at that point you can feel free to delete the 0.11.1 wheel that is there now.

[matthewfeickert]

@henryiii Just checking in to see if you have any questions on this.

[henryiii]

I've generated and added the token.

[matthewfeickert]

I've generated and added the token.

Great. Are you planning to add a GitHub Actions workflow to upload nightly releases?

[henryiii]

How often should I upload nightlies? Every night if there are changes? Do you have an example of something similar (a lightweight Python only package, ideally)?

[matthewfeickert]

@henryiii yes, as frequently as possible. It is okay to even have a cron job that does so nightly regardless of changes. I'm on my phone as I'm heading to the airport, but both Awkward and Uproot have workflows that do this.

Also c.f. the comment in the checklist post RE: collection workflows.

[matthewfeickert]

Thanks @henryiii! With PR scikit-build/scikit-build-core#1081 merged in you're now uploading nightly wheels and everything is good to go. 👍 I'll close this out now.

What about pybind11?

@henryiii That would be very welcome too! This is now Issue #134.
