### 28 Oct 2020 Weekly Meeting

- Alex
- Discovered [#9234](https://github.com/jupyterlab/jupyterlab/issues/9234) while updating Elyra to use JupyterLab 3.0, disabling extensions no longer works in 3.0. IMHO this is a release blocker, but I've so far had no luck tracking down the source of the issue, I would love more eyes on it.
- Brian
- I have pulled the JupyterLab survey into a PR to team-compass to make it easier and more transparent for every to provide feedback and iterate.
- https://github.com/jupyterlab/team-compass
- Not able to attend the meeting in person today, but I have cycles to put into this, address feedback, etc.
- Isabela
- Jupyter Community Calls. I want to move the meeting dates for the next few months to avoid some U.S. holidays. Can I update this on the [community calendar](https://jupyter.readthedocs.io/en/latest/community/content-community.html#jupyter-community-meetings)?
- Change November 24 to Nov 17
- Change December 22 to Dec 15
- Consider promoting survey at first calls if it is open.
- Jason
- [JupyterLab 3.0](https://github.com/jupyterlab/jupyterlab/milestone/48), yet again :)
- Back up to 12 issues, 2 outstanding PRs.
- [UX issues](https://github.com/jupyterlab/jupyterlab/issues?q=assignee%3Aellisonbg+is%3Aopen+milestone%3A3.0) (Brian?)
- Extension system polish: documentation, information for extension manager
- Eric
- [List the dynamic extensions in the extension manager](https://github.com/jupyterlab/jupyterlab/pull/9236)
- [Enable dynamic?federated extensions in dev mode](https://github.com/jupyterlab/jupyterlab/pull/9236)
- Will work to nail down the performance issue root cause and try to connect on the findings
- Luciano
- Git extension moving to JupyterLab 3.0 ETA?
- In url madness, a few things broken on Elyra after upgrading to lab 3.0 as path can't find `process.cwd`. Moving to lab URLExt to use same tools and see if help on the issues.

- Additional Discussion

### 21 Oct 2020 Weekly Meeting

- Alex
- Have not had bandwidth to start on [Settings UI](https://github.com/jupyterlab/jupyterlab/issues/8148) due to JupyterCon, will be busy catching up on other tasks this week, will probably start on it next week. Still open to having others help out if theres interest.
- Question: I'm currently working on updating Elyra to JupyerLab 3.0 rc5 and am confused by the new federated build system. If extensions now require all these new build files why do the core extensions not have them? Is it possible to script thier creation in some way?

- Release 2.2.9 - https://github.com/jupyterlab/jupyterlab/issues/9160
- In particular https://github.com/jupyterlab/jupyterlab/issues/9159

- Bi weekly live stream on working with Lab extensions (2pm EST) https://youtu.be/4445MZkNszY
- Brian:
- UX of single document mode
- Let's open 1 issue, as there are many subtle, interrelated aspects)
- https://github.com/jupyterlab/jupyterlab/issues/9117
- Not sure that "single-document mode" really captures the idea well, maybe "Classic"?
- "Zen mode" is common as well. "Focus mode"?
- Does new *Jupyter* users know what "classic" implies?
- We've been putting a lot of branding effort into calling the Jupyter Notebook "classic"
- Other extensions add content to that space, not sure how it will scale.
- RTC+Yjs
- I am going to start working on integrating Yjs into JupyterLab master.
- I have met with the lead of Yjs (Kevin) and talked about porting relevant aspects (schema's specifically) over to Yjs, Python implementation, etc.
- Ny focus will be on getting working RTC+undo/redo to users as fast as possible, with as few breaking changes as possible.
- PRs to master, but also possibly separate extensions that work before 4.0.

- Discussion
- JupyterLab release timeline

### 19 Aug 2020 Weekly Meeting

- Gonzalo:
- JLab UI - Devtools menu?
- Dev tools Menu?
- With the localization work I added `!!` to have visual cues of strings that I had not yet captured to translate. It would be handy to be able to set this in a menu Dev tools or something, and eventually adding there the commands that would extract the translatable strings for extension developers. I guess there are more “tools” that would make sense to go here.
- Workspace in title demo
- Should the statedb update if it starts and some files were not available for open?
- How to check if a given "file/notebook" is open
- Configurability?
- Single mode just display active thing?
- Spellcheck extension dictionaries bundle with language packs?
- Talked with Michal, see: https://github.com/jupyterlab/team-compass/issues/85
- Steve
- Working through module federation usability - [cookiecutter](https://github.com/jupyterlab/extension-cookiecutter-ts/pull/73) then the APOD tutorial
- Fixed `watch` mode in [core](https://github.com/jupyterlab/jupyterlab/pull/8841)
- Fixed a minor security issue relating to tokens in [URLs](https://github.com/jupyterlab/jupyterlab/pull/8835)
- Jason
- Working through polishing module federation, and populating our example with various usecases like phosphor shim, etc. [Project board](https://github.com/jupyterlab/jupyterlab/projects/10)
- JupyterCon JupyterLab tutorial: https://docs.google.com/document/d/1MnqeI1flbPT-kSuG_VdmyTrKIhyWU8Xhu_1L8kk0RxU/edit?usp=sharing
- Shadow DOM: https://github.com/jupyterlab/jupyterlab/issues/8843, https://github.com/jupyterlab/jupyterlab/pull/8584#issuecomment-675841754
- json-extension renderer: react-highlighter - gives react error and deprecation warnings. It would be great if someone can look into replacing or updating react-highlighter
- Eric: Will work in the coming days on:
- Side effects after migration to Jupyter Server? (base_url, favicon, workspace clone): https://github.com/jupyterlab/jupyterlab/issues/8856
- Performance
- Run comparison for Shadow DOM with a manyCells notebook https://github.com/jupyterlab/jupyterlab/pull/8584#issuecomment-675879714
- Preliminary benchmarks with content-visibility css class (chromium 85) https://web.dev/content-visibility show huge improvement.
- Working on Intersection Observer for notebook cells (2 options: VirtualNotebook lumino-based, ReactNotebook react-based and wrap it into react-virtualized)
- Cocalc only does virtualization above a certain number of cells, and that seems to work well
- Another option we've discussed in the past is a table-based layout, which helps with accessibility as well
- POC of Lumino-in-React with a LuminoAdapter (reverse of our React-in-Lumino ReactWidget)

- Isabela and Layne
- We should discuss and comment on the goals of the survey.

- [x] Twitter.
- [x] Discourse.
- Who has access/maintains the jupyter.org page (seems a bit dated?)
- [ ] Make a PR
- Packages:
- Need to publish the companion packages to extract strings (https://github.com/goanpeca/jupyterlab-translate/) and generate the language packs(PiPy Bot/JLab account?) (https://github.com/goanpeca/jupyterlab-language-packs) plus a language pack cookiecutter (https://github.com/goanpeca/jupyterlab-language-pack-cookiecutter)

- Open a team-compass issue about these and we should move them over.
- Move them to the org? the language packs repo and the translation utils?
- Documentation
- Need to write on localizing the code, patterns, dos and don'ts etc. Where should this go?
- Docs (there are extension development docs)
- Like this [React docs](https://jupyterlab.readthedocs.io/en/stable/developer/virtualdom.html) but for localization?

- Migrating extension 2.x -> 3.x: Is there such a page to add the breaking changes? (not much! almost all is optional)
- For JLab 2, we had both the changelog and a separate page for updates developers needed to do. If it is a small list, let's put it into the changelog. If it is a larger page with lots of examples, etc., let's make it a sibling to the jlab 2.0 ping to the jlab 2.0 ping to the jlab 2.0 ping to the jlab 2.0 p
- Update the cookiecutter. See https://github.com/jupyterlab/extension-cookiecutter-ts/issues/72
