### 25 August 2021

**Note**: Live notes for today's meeting will be on [Binder](https://hub.gke2.mybinder.org/user/afshin-d1094371-3ed2615445a74b7-lh1ad6u5/lab/tree/agenda.md?token=ZFi1-1oISFWW-l8Abw0_5w)

* Frederic:
* Translations
* CSS Icon deprecation [PR10908](https://github.com/jupyterlab/jupyterlab/pull/10908)
* Galata [PR10796](https://github.com/jupyterlab/jupyterlab/pull/10796) in 3.2.x as @jupyterlab/galata@4.0.0

* Jason:
* Assigning issues - we have a number of people requesting issues be assigned to them in the GitHub interface so that they can work on them. Sometimes these new contributors are optimistic about fixing an issue and a PR does not eventually come, but the issue is not ever unassigned (thus it appears to be "taken" to other new contributors). I would suggest as a policy that either:
* in general, we not assign an issue to a person (an exception would be assigning a short list of issues to people in the final phases of a release when there is time pressure to finish that final set of issues, and we are documenting a short time-limited commitment from people to fix issues before a release)
* or at least that we not assign an issue to a new contributor until after they have submitted a reasonable PR fixing the issue.

### 9 June 2021 Weekly Meeting

* Gonzalo
* Would there be any interest in the development of an open source jupyter notebook metadata extension that could take in an end user json-schema to extend the notebook metadata and then display a gui for editing those fields in the notebook?
* Old reference [issue]
* Widget forms of react jsonschema from https://github.com/deathbeds/wxyz/blob/master/src/wxyz_notebooks/src/wxyz/notebooks/Examples/JSON%20Schema%20Form.ipynb ?
* lresende - this is mostly available in Elyra for metadata based on jsonschema with an editor capable to generate forms from the schema. We can collaborate and split this piece as required. In the past there was interest on moving the metadata service to JupyterServer and we could enable the editor on lab/lumino.
* jupyter lab starters exposes this with trailets configurations using rjsf https://jupyterstarters.readthedocs.io/en/latest/ ?
* PR Ready https://github.com/jupyterlab/jupyterlab/pull/8713
* ZenHub demo for the issue discussion

* Frederic
* Refactor UI components
- Go for it
- Look about the component for the modal palette - probably needs discussion; check if this is only a Lumino thing or Lab one.

* Max
- weird theme bug
- linked sheets are not getting unloaded the way they used to
- something about a how the css from a federated theme extension is loaded?
- https://github.com/telamonian/theme-darcula/issues/32

- one last sticking point for [#9488](https://github.com/jupyterlab/jupyterlab/pull/9488): "disable autoClosingBrackets by default everywhere"
- what is `handlePaste` and why is it sometimes set as part of the fileeditor options?

* Kevin
- Any feedback for RTC Jupyterlab?
- discovered on call: tab setting in editor (maybe also language highlighting setting), theme syncing

* Steve
- [JupyterLab 3.1.0a12](https://github.com/jupyterlab/jupyterlab/releases/tag/v3.1.0a12) with some new goodies:
- select all cells with tags in toc
- build menus from settings
- new widget area below the dockpanel
- [ipykernel 6.0.0rc0](https://github.com/ipython/ipykernel/releases/tag/6.0.0rc0) - the main feature for 6.0 is an implementation of the debugger protocol. 🎉

* Jason
- Editor design and dependencies: https://github.com/jupyterlab/jupyterlab/issues/10352

- Layne (if time allows)
- Jupyter = NumFOCUS UI.
- Dask = NumFOCUS at scale (pd, np, sklearn, generic Python objects).
- Integration of Dask UI/admin/config in Jupyter core. Ever been discussed?

### 5 May 2021 Weekly Meeting

- Isabela
- What are the plans to convert all the roadmapping work and documents used in these meetings to the [4.0 roadmap issue](https://github.com/jupyterlab/jupyterlab/issues/9647)?
- Next steps are to get names on the empty parts of spreadsheet via the meeting Darien is coordinating with people looking for projects to contribute to ([jupyterlab/team-compass #124](https://github.com/jupyterlab/team-compass/issues/124)).
- Should be linked on main JupyterLab 4.0 issue.
- Once all areas are filled out, this needs to be made markdown and tied to the main issue for reference.
- Thanks to Jeremy for running this meeting!

- Frederic
- Hello
- Discussion on cell toolbar [#9733](https://github.com/jupyterlab/jupyterlab/issues/9733) - does it make sense to bring the [cell toolbar](https://github.com/jupyterlab-contrib/jlab-enhanced-cell-toolbar) extension in core?
- Menu items filtering [#10091](https://github.com/jupyterlab/jupyterlab/issues/10091) - first trial by explicitly listing command ids to hide thanks to the `isVisible` property [PR](https://github.com/jupyterlab/jupyterlab/pull/10191). The trouble comes from the need to modify the commands where they are defined. So an approach inside the lumino `Menu` sounds more generic. If some have suggestions or comments that would be nice.

- Maggie and MJ
- Questions about jupyterlab build process https://jupyterlab.readthedocs.io/en/stable/user/directories.html?highlight=dependency#jupyterlab-build-process
- How does it resolve sub-dependencies versions of installed extensions? It seems it always installs the newest dependencies available that meets the semver range in the extension's package.json, instead of by package-lock or yarn.lock. Is it expected or is there specific reason?
- 2 layers: application level (lumino) get resolved at the top level. other dependencies, use webpack to find the compatible version. The package-lock in extension itself is ignored.
- JL v1 uses webpack module resolution by default. JL v3 has custom settings under builder subfolder.
- Any recommendation how extension can specify specific sub-dependency versions to be installed? We tried to pin the version in "dependencies" and "resolutions" in extension's package.json, but didn't help.
- Since JL v1 doesn't have custom way to resolve dependencies, we should look more into general webpack documentations and solutions.

- Max
- The successor to `data_files` in jupyter extension python packages
- not my work, i've been getting caught up on @bollwyvl and @jasongrout's work
- lots of work has gone into experimenting with `entry_points`:
- https://github.com/jupyter/jupyter_core/pull/209
- totally functional, but creates a performance issue
- no matter what, using `entry_points` means searching 1000s of paths for plugins/config at startup
- what's the current state of this work?
- recently, our quest to replace `data_files` has attracted interest from some core PSF folk
- https://discuss.python.org/t/should-there-be-a-new-standard-for-installing-arbitrary-data-files/7853/76?u=telamonian
- summary:
- install by adding to a particular path in a wheel

        {distribution}-{version}.data/data/share/jupyter

- may need changes/improvements to build tools to actually do this
- in runtime, fetch data file paths with

        Path(sysconfig.get_path("data")) / "share/jupyter"

- simple, skips the inherent performance issues of `entry_points`

- Kevin
- Let's merge the [RTC PR](https://github.com/jupyterlab/jupyterlab/pull/10118)
- We need more feedback / people trying out he PR in practice.
- ~~There is only [one smaller issue](https://github.com/jupyter-rtc/jupyterlab/issues/72) that we need to fix before the PR~~ (fixed it)

**Additional Discussions**:

- Let's postpone the “What should I work on?” 4.0 meeting to next week: https://github.com/jupyterlab/team-compass/issues/124

### 28 April 2021 Weekly Meeting

- a draft of an idea for a lines format https://nbviewer.jupyter.org/gist/tonyfast/707ea716d9d413feef184e7bdbb67a93
- "What should I work on?" -- [JupyterLab 4.0](https://docs.google.com/spreadsheets/d/1r6_ySd18xZwfPexdmlkdFhHUWynaza0zXjrxMMIoLWw/edit#gid=0) feature-pairing meeting: [`team-compass` issue to schedule a call](https://github.com/jupyterlab/team-compass/issues/124)
- Martha
- Question on small lumino change: https://github.com/jupyterlab/lumino/pull/174
- Vidar
- Q: Is it possible to have CDN based federated module loading?
A: Yes, but requires disting of build outputs to the CDN + ensuring that the URL matches up with the request URL. There shouldn't be any processing of these files on the server.
- Q: How comfortable are we with storing deploy-level secrets for automated deploy ? What are actions we can take to ensure there is a manual gating for releases to help harden things ?
A: We can have a manual GHA job that deploys versions, where the deploy step that has access to the secret does not use any external actions.
- Luciano
- nbdime and git extensions now have GA releases supporting Lab 3.0. Thank you all for helping with that. That unblocked Elyra to push its packages to conda-forge.
- Ross

### 07 April 2021 Weekly Meeting

- Isabela
- Accessibility meeting is today fifteen minutes after this call!
- Current work in progress includes `skiplink`, [#9622](https://github.com/jupyterlab/jupyterlab/pull/9622), and figuring out automated testing strategies.

- Mehmet
- Galata is now integrated with ipywidgets and bqplot. Used for visual regression testing for PRs, via GitHub Actions
- Integration to ipywidgets
https://github.com/jupyter-widgets/ipywidgets/pull/3172
- Example run in ipywidgets
https://github.com/jupyter-widgets/ipywidgets/runs/2235751369?check_suite_focus=true
- Integration to bqplot (done by Martin @ QuantStack)
https://github.com/bqplot/bqplot/pull/1311

- Tony
- react aria for accessible react components https://react-spectrum.adobe.com/react-aria/
- Ani
- Demo of Kernel Specification Manager and feedback!

- Jason
- On HackMD, disable "nyan cat" and "power mode" by clicking on the wrench in the status bar
- [Support notebook format 4.5 (cell ids)](https://github.com/jupyterlab/jupyterlab/pull/10018)

- Jessica
- User experience of name notebook on save
- https://github.com/jupyterlab/jupyterlab/issues/5207
- https://github.com/jupyterlab/jupyterlab/pull/10043

- Mike
- How do we work with extra columns/decorators in the file browser:
- example issues/PRs:
- jupyterlab: ["toggle last modified column" does not work](https://github.com/jupyterlab/jupyterlab/issues/8860#issuecomment-809672555)
- jupyterlab-git: [add colours for added/modified/deleted files in file browser](https://github.com/jupyterlab/jupyterlab-git/pull/885#issuecomment-787462919)
- also show the number of linter errors?
- possible solutions:
- current approach: inherit from file list renderer and swap the default renderer? does not work when multiple extensions try to modify it
- better approach: add a lumino's Signal as a hook in the renderer to add custom columns and decorators in extensions?
- proposal: add columns as a first-class citizen, expose API like `registerColumn()` and `toggleColumn()` (issue to be created)
