Agenda

• Frederic

  • PRs reviewer wanted:
    • Use path to extract tmpPath (Darian will review)
    • Update snapshots for challenger commit
  • Add a doc section: automation with Vagrant
    I'm not in favor to document automation with a specific tool in the documentation (because there are so many).
    So what would be the best approach to add this? Maybe linking to a gist for a given tool?
    • Linking to Gists as a policy opens us up to bait-and-switch security issues, where a malicious actor could propose linking to a gist they control, then later updating the gist to do something malicious.
    • In general, some problems are:
      1. Picking winners, or alternatively bloating our documentation with a confusing array of possibilities
      2. Maintaining instructions that no one in the project is using. Perhaps we only accept the contribution if the original author commits to maintaining the instructions, and when it falls out of date and is not updated, we remove it?
    • Conversation from the dev meeting indicates preference for other solutions to setting up a dev environment (for example, using conda/mamba tools, etc.). @bollwyvl has some suggestions, for example:
      • this one that drives jlab-desktop: https://github.com/jupyterlab/jupyterlab-desktop/blob/master/env_installer/construct.yaml. the actual tool is https://github.com/conda/constructor
  • CodeMirror v6 has been merged in master: please test it and report bugs
    The follow-up issue is at #12812
  • Drop of CodeEditor facade: what to keep/remove? e.g. should we move to offset positioning (CM6 does not use {line, col} any longer).

• Max

  • improvement to readonly UI
    • issue at #7980, draft PR at #12826
    • open to suggestions on design/style improvements
  • followup to improved readonly UI: show Toast on failed save attempt
    • Original toast issue: Create proper notification system and area - Toast Notifications jupyterlab#689
    • Max would like to add an existing quality Toast implementation to jlab: #12827
    • eg two reasonable choices of Toast component:
      • material-ui Snackbar
        • looks good
        • super flexible
        • con: have to bring in the large mui package, though in theory tree-shaking should mitigate this
          • @ajbozarth has been using material-ui snackbar in elyra, and likes it
      • light-toast
        • small (5 kb as per bundlephobia)
        • con: smallish user base
      • In jupyterlab-toastify, react-toastify is used.
    • Recently we had a vote adopting fastui as a component library
      • Note that FAST UI is not the same as Microsoft's FAST design system
  • Real-time sync and the save button
    • Some might suggest that RTC might make the save button obsolete
    • William suggests that "save" doesn't go away with RTC, because "save" indicates serializing the file to disk, as opposed to syncing with everyone else. In Cocalc, saving by default happens every 30 seconds or when explicitly requested, or when the page closes. A user might want explicitly save because there may be other things watching the file that activate on save, like building a tex file, etc.
    • (my (Vidar) understaing is RTC will autosave to disk. There is also currently an auto-save of files in Lab)
    • william: In the experimental version of JupyterLab RTC that I just tested it's a mess with clicking save causing warning messages to popup, as if rtc isn't used. Another remark is that save-to-disk WILL sometimes fail (e.g., lost network, filesystem switches to read only, filesystem is full), and it's really important to have a persistent message to user about this.

• Darian

  • Voting timeframe: JupyterLab Council voting timeframe #154

Additional Discussion

• Report from Scipy 2022
  • Tutorial
    • 15-20 people there, so about 1/4 of normal attendee numbers. It seemed all tutorials numbers were down at the conference.
  • Significant mentions of JupyterLab
    • Papyri talk by Matthias demoed Papyri in JupyterLab
  • Scipy is going to be planned by NumFOCUS moving forward, may move from Austin in the future.

Agenda

• Isabela

  • JupyterLab accessibility meeting will be fifteen minutes after the scheduled end of this one! Hooray!

• Frederic

  • JupyterLab 3.4.5 has been released

  • 2FA enforcement - 2 possibilities

    • Enforce it and get people notify they have been removed as collaborators
    • Ping people lacking 2FA on private discussion (one has been created by Matthias - github: @Carreau)

    We will go for the gentle ping on people - the enforcement is planned by the Jupyter security team by the
    end of september. So this left a good amount of time for collaborators to add 2FA.

• Darian

  • Lumino 2 project board and call for help
    • [name=gabalafou] If there are necessary API changes for accessibility concerns, now is the time to outline them; otherwise will have to wait for Lumino 3. Identify accessibility targets for Lumino 2 #341

• Mike

  • shout out to JupyterLab Desktop which would benefit from more help, also see Really bad first-time user experience jupyterlab-desktop#477
    • unrelated, but the similar effect: https://stackoverflow.com/q/73278038/
  • environment selection in JupyterLab Desktop Environment selection dialog improvements jupyterlab-desktop#479
  • seeking feedback on .jupyter for pre-proposal default workspace and setting Project concept support via a hidden directory jupyterlab#12916
    • Vidar: VScode has right-click bringing up last projects
    • Perfer having less files than more so that is not too noisy for git users who want to store it

Agenda

• Frederic

  • PRs to be reviewed:
    • Increase translation coverage
    • Prompt for renaming at first manual save -- Piyush volunteers
    • New extension manager
      • Can be used in readonly mode to list all installed extensions (Thank you!!!!)
  • Fighting with some stall ones: Remove modelDB and Virtual notebook
  • EuroScipy 2022
    • Poster for JLab 4 / Notebook 7
    • Talk about JupyterLite
      • Gonna be one about Pyodide and another about PyScript too

• Darian

  • More Lumino 2 updates: JupyterLab 4 Lumino migration

  • Lumino 2 migration guide (partial)

  • Software Steering Committee discussion

• Sylvain

  • FYI - since JupyterLab has migrated to CodeMirror 6, some extension will require some significant updates.
    • LSP (as discussed previously), but also jupyterlab-git.
    • JupyterLab git will require to implement a "merge view" for CodeMirror 6.

Additional Discussion

• FYI: ipywidgets 8 was released last Thursday. Changelog. If you are having issues with ipywidgets 7 since last Thursday (when doing a pip install), it may be that pip install ipywidgets is pulling in the wrong version of jupyterlab_widgets. Please make sure to upgrade to ipywidgets 7.7.2 or ipyiwdgets 7.6.6, since they depend on the correct version of jupyterlab_widgets for ipywidgets 7 (or pin your version of jupyterlab_widgets).
• FYI: nbgrader extension 0.8.0 for JupyterLab as been released: 0.8 Release Plan jupyter/nbgrader#1634 (comment)

Agenda

• Jason W

  • Move triage from Thu 10:00 PDT (17:00 UTC) to Wed 10:00 PDT (17:00 UTC)?
    • For the time being, the current time slot seems least contentious, but we should think about other times.
    • Use triage to attack backlogs as well, by reviewing older issues weekly?
    • PR reviews?

• Mike

  • Python Logo for Python scripts: blue or as for kernels: Trademark issue with wrong use of an altered Python logo in Jupyter Lab Launcher jupyterlab#13023
    • One solution for this is in: prefer new .jp-icon-mono class for monochromatic icons jupyterlab#12673
  • nbformat, trust and signature: Should kernel info be included in notebook signature computation? jupyter/nbformat#296
  • opinions on ways to sort in PyPI extension manager? New extension manager jupyterlab#12866 (comment)

• Darian

  • Update to Lumino 2 (needs another rebase, but almost there)
  • Governance update:
    • By 3 October, we should have the JupyterLab Council fully selected (this does not mean we stop here, just that by this point, it should be representative)
    • By the same date, we should select our Software Steering Council representative
    • If you would like to nominate somebody for the SSC, they must be a member of the JupyterLab Council, they must be willing to accept your nomination, and they need to know that they cannot be both on the SSC and on the project-wide Jupyter Executive Council. So if they would like to run for the Jupyter Executive Council, they should consider whether they are interested in representing JupyterLab in the SSC, because they can only do one or the other.
    • @fcollonval has created a form for nominations. Please make nominations by 15 September so that we have enough time to vote.

Agenda

• Frederic (unlikely to join)
  • JupyterLab 3.4.6 and 4.0.0a28 (first release with Lumino 2.alpha) released
  • EuroScipy 2022 feedback
    • Poster got lots of interest:
      • No strong complains from users
      • Some people took the game at finding differences between Notebook 6 and 7
    • JupyterLite and others talks about science with Python in the browser got people very enthusiastic
      • Some tutorials were using JupyterLite
      • Talk about education displayed a Python introduction example using JupyterLite: https://sportspython.github.io/jupyterlite_test/lab
  • CZI EOSS 5 grant application for supporting JupyterLab 4 / Notebook 7 was rejected
  • Issue open to list PR candidates for JupyterLab 3.5.0
• Gabriel and Kulsoom: question for @jweill-aws, could you summarize, give context to the cell toolbar css rules in lines 14-43 in base.css
  • These are all used for the cell toolbar added to JupyterLab 4.0 and 3.4.x earlier this year. The toolbar appears on every cell, in desktop and mobile web views, as long as it does not overlap with its content. If you have further questions, I'd be happy to set up a call: please write to me at jweill@amazon.com. — @jweill-aws
• Darian
  • jupyterlab/council repo
  • Pinned hosting signup issue
  • Lumino 2 migration:
    • Bump to Lumino 2ᵅ⁶ jupyterlab#13062
    • Lumino 2 moved to ES2018 compilation target so we get native async iterators. All modern browsers support async iterators, with Edge being the last one in 2020.
• Vidar
  • Question around 3.x benchmarks / performance
  • Related discussion on Discourse
• Isabela
  • JupyterLab accessibility call will be fifteen minutes after the scheduled end of this call. All are welcome!

Additional Discussion

• @blois
  • Portable rich outputs (Improved %%javascript cell magic. ipython/ipython#13376 (comment))
  • Initial rough prototype: https://github.com/blois/js-module-renderer/
  • Basic idea: a mimetype for javascript (or typescript?) that exposes an api to the code to do things like connecting to the kernel, getting a DOM element, creating a comm, etc.
  • The api would be very minimal and immutable, e.g., no breaking changes
  • Using arraybuffers and /files as a base model for files jupyterlab#4902
  • Places appropriate for this conversation
    • JupyterLab, IPython for implementations
    • Jupyter Standards
