Closes #3285

TODO

• [x] Format changelog so it's compatible with the releaser
• [ ] Check whether we can keep the current changelog for 8.0
• [ ] Do we want to version and release packages separately -> for now we'll version and commit separately (like for lumino)
• [ ] bumpversion / tbump for bumping the Python packages? -> tbump can be used for each of the Python packages
• [ ] Check how to handle ipywidgets depending on jupyterlab_widgets and widgetsnbextension: https://github.com/jupyter-widgets/ipywidgets/blob/441135a3c24df7ccbee8216a627bb3eb75b9ee23/setup.cfg#L42-L43 -> check how the releaser handles this
• [ ] Check if the releaser can skip packages already published

:point_left: Launch a binder notebook on branch davidbrochart/ipywidgets/jupyter_releaser

[davidbrochart]

The bump-version.py script was copied over from Voilà, but I guess it has to be adapted to work here?

[davidbrochart]

I ran "Draft Changelog" on my branch. From the logs, it looks like we would need to install JupyterLab in the draft-changelog action (because bump-version.py needs jlpm)?

Thanks @davidbrochart for starting this!

it looks like we would need to install JupyterLab in the draft-changelog action (because bump-version.py needs jlpm)

Or we use yarn instead of jlpm? Since ./dev-install.sh also uses it to setup the development environment.

[davidbrochart]

Actually I was missing some Jupyter Releaser hooks. But the problem is that the bump-version.py script needs lerna to be installed.

[jtpio]

Normally lerna should be installed when running yarn at the top level of the repo. So maybe we can keep that hook and run yarn instead of jlpm.

@davidbrochart let's convert the PR to a draft while we iterate on it

[jtpio]

For reference the current release instructions are in https://github.com/jupyter-widgets/ipywidgets/blob/master/docs/source/dev_release.md. And it looks like the versioning is done manually by running the yarn run version command which calls lerna version:

Edit: moving the TODO to the top comment.

OK this is kind of weird. The check seems to be canceled sometimes after 1 minute, sometimes after 5. This one for instance: https://github.com/jupyter-widgets/ipywidgets/pull/3298/checks?check_run_id=3940082517

[jtpio]

sometimes after 1 minute, sometimes after 5

1 minute is probably because of https://github.com/jupyter-widgets/ipywidgets/pull/3298/commits/ef786ca4a00d90e4da97c5b51b42f83eec57d7ed which removed the explicit install step. But it's strange that it is canceled instead of exiting on error.

[davidbrochart]

Isn't it because when link_check fails, it cancels check_release?

[jtpio]

Ah right, we are not using fail-fast: false for now: https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#jobsjob_idstrategyfail-fast

We can set it for now so it's easier to debug.
