PRs needing review

• Refactor status bar jupyterlab#11450
  • @3coins, will review this

Agenda

• JupyterLab 3.3 - List of features to include:

  • JupyterLab 3.3 Release jupyterlab#11643
  • We need to fork before the PR merged in 3.2.x that target 3.3
  • [discussion about the issue about the blank terminal when reopening] William in CoCalc is dumping the history in a file. Nick proposed that terminado should be extended to support that feature.
    • william adds: "In CoCalc a terminal session corresponds to a file (with extension .term) similar to how a notebook has a corresponding file, so it’s a very natural place to store the recent terminal stream. However, having terminals correspond to files is a very uncommon design. It’s useful for realtime collaboration though."

• Frederic

  • Issue following Delay list -> dict conversation to end (Project update by SSC to EC #192) reverted for now @ vidartf
  • Alternative solutions:
    • Make merge method also merge lists.
    • Update everything to accept the new behavior
    • Have get_page_config take a "base" argument
    • others ?

• Isabela

  • Jupyter accessibility workshops are coming soon! The first two are January 15 and January 22 (times on the community calendar)
  • Would some one mind reviewing the submitted Jupyter blog post for announcing the workshops?
  • Command palette has something styled like a button that is not actually a button. This seems like bad practice. (Originally discussed on jupyterlab/jupyterlab #11658

• Johan

  • Migration to CodeMirror 6: syntax highlighting is back

• Jason W

  • Triage process has been checked in; please keep an eye on issues tagged with status:Needs Triage

    • New signal, sourceChanged to the CodeEditor.IModel.
    • The arguments of sourceChanged are similars to the ObservableString.
    • Duplicated signal when the source or the metadata changes, we emit contentChanged plus sourceChanged/metadataChanged.
    • I made ModelDB and sharedModel private.

  • Remove metadata from ModelDB:

Agenda

• Eric

  • Demo KSMM (Kernelspec Manager) extension https://github.com/deshaw/ksmm

    • [1] Create / Edit / Delete Kernelspec from Jupyterlab [2] Parametrized Kernels

    • Feedbacks and contributions welcome 👍
      Lots of interest on discussing a formal way to parametrize the kernel specifications.

    • Can be useful input to setup a working group on Parametrized Kernel Parameterized Kernels jupyter-server/team-compass#16

    • [Mike] list of kernels in reply to an question of Layne: there is https://docs.jupyter.org/en/latest/projects/kernels.html and https://github.com/jupyter/jupyter/wiki/Jupyter-kernels

• Trung Le

  • Refactor completer package (Refactor completer and completer-extension package jupyterlab#11795)
    Demo supporting multiple providers.
    [Nick] It will be nice to provide the settings with a priority instead of the list of providers to ease dealing with config merge: "selectedProviders": {"CompletionProvider:tabnine": 0, "Completionprovider:base": 1}
    [Nick] Out-of-scope for that PR: it will be nice to rework the model/renderer API to add the ability to reuse the model to display completion at other places (like in a separated label)

• Jeremy

  • New releases: 4.0.0a19, 3.2.7, 3.1.19
  • Investigating CI failure related to IPython 8
  • Planning to release 3.3.0a1 when the CI is fixed

• Jason W

  • Triage process is now in place. Some issues still coming through without label. How often to triage issues?
  • Public service announcement: check the issues in need of triage when you get a free moment. If an item is ready to work on, remove the status:Needs Triage label. If you have questions, add a comment and add another tag like status:Needs Info. We should aim to have new issues triaged within about a week.
  • Add a new section to the notes with the list of issues in need for triage to bring light to them.

• Ahmed

  • Question about intermittent gutter clipping underlying code cells in JupyterLab 2 and 3
    • https://gist.github.com/fasiha/ec1172a7eed75a66c5e5ce70fd07e810 GitHub issue coming! 🚀
  • @jasongrout: My guess is that this has to do with CodeMirror running a .refresh() when the cell is activated. My guess is that something is changing the codemirror or adding something to the gutter without calling .refresh().

• Darian

  • Software Steering Council + decision making body

• Alex

  • Archived the hackmd for Q4 to help with lag https://hackmd.io/zFgZGFsOSw6b6cKFYST4Qg?view

• Frederic

  • DOCS: Convert theme to pydata-sphinx-theme by Chris Holdgraf: see preview there

Additional discussions

• [jasongrout]: From the completer PR demo, it seems we need a way to display a list of dynamic things for information.

  • Can probably be side-stepped for this PR if switching to dict instead of list, as the default value can then be used as the information communicator as well.
  • There seems to be an existing pattern that allows this by using settings tranformers to add dynamic content descriptions? Keyboard shortcuts, for example, lists the available commands in the description.
  • It would be good if enums etc from the schema could be presented well in the editor.

• [Nick] A new version of JupyterLite has been released: v0.1.0a19

• @jasongrout: Experimented with autocomplete over the control channel so it isn't blocked by execution. If you know of problems with this, please comment on the draft experiment PR: Experiment sending the complete_request message on the control channel. jupyterlab#11831

Agenda

• Jeremy

  • 3.3.0a1 is out: https://github.com/jupyterlab/jupyterlab/releases/tag/v3.3.0a1
  • New alpha release when the js-apputils CI check is fixed: js-apputils check is failing on CI jupyterlab#11886
  • Drop nbclassic draft PR: Drop nbclassic, depend on notebook_shim jupyterlab#11894
    • There is an issue about the future of nbclassic and having a nbclassic-shim package: The future of nbclassic jupyter/nbclassic#81

• Isabela

  • January's Jupyter community call is next Tuesday. It's the first of the year! Get more info on the Jupyter Discourse.
  • There is a Jupyter accessibility workshop this Saturday! We'll be sprinting on documentation with low-code and code-heavy topics (depending on your interest). You can register via Hopin
    - Possible testing resource demoing axe testing in playwright.
  • If you have an accessibility-related topic you'd like to sprint on in the future, reach out to me! We'll be planning another sprint in March and are still open to topics.

• Frederic

  • JupyterLab Performance meeting after this one.
  • Automated screenshots for documentation

• David

  • ZeroMQ and websocket protocols alignment PR: jupyter-server PR
    Companion PR on JLab
    The goal is to avoid de/serialization of JSON and transfer raw bytes.
    [Mike] Is performance gain notable?
    Around 40% on function levels
    [Nick] i think any binary spec should be more robustly characterized with e.g. kaitaistruct we don't want to end up in the situation where the as-written spec is eclisped by a particular reference implementation

Additional discussions

• [Vidar]: Target date for 4.0

  • Estimation is around end of Q1
  • There is a need to avoid big changes in the upstream JupyterLab used for notebook v7 just after notebook v7 is released to avoid discouraging people taking the path to port their extensions to notebook v7

• [Nick]: How to support custom desktop App with pre-loaded environment and extensions?

  • [Mike] On one level it is "just" customizing the constructor yaml list: https://github.com/jupyterlab/jupyterlab-desktop/blob/master/env_installer/construct.yaml but yes, having a cookiecutter at some point would be great.
    • JupyterLab Desktop could become more modular:
      1. default conda environment
      2. electron integration
      3. core Desktop extensions on top of JupyterLab. We could allow downstream to swap (1) and (3)
  • [Nick] Example of customization distributions:
    • https://github.com/gt-coar/gt-coar-lab
    • https://github.com/robots-from-jupyter/robotlab/
    • https://psicode.org/installs/v15/
  • A way to get conda environment by the user in desktop app is to use a package manager like gator

Agenda

• Frederic:

  • Style linter by Nick
    • cookiecutter
    • can encode accessibility constraints eventually
  • Markdown parser in its own plugin
  • Settings UI has been merged in master 🎉
    Thanks a lot to Martha and every one involved in testing and reviewing

• Jason W:

  • RetroLab left/right panel item has been in WIP for a while — next steps?
    • ToC needs some additional refactoring in JLab to move forward on that PR.

      • [nick]: recommend Inspector ne Contextual Help (appears in notebook 6 in the bottom region)

• Tony Fast

• Jason G:

  • Keyboard shortcut display - anyone is welcome to help push it forward
  • Lots of commands do not have captions, and some don't have labels

Additional discussions

• Keyboard layout & shortcuts discussions:
  Those are two different subjects. The handling of the layout is addressed by Lumino (it deals with mapping key code to the character). The shortcuts discussion is about being able to get the sequence of keys that trigger an event.
  Bottom line is for Codemirror hard coded shortcuts (in extensions) we should override them in JupyterLab, otherwise we have issues like
  • JupyterLab Issue: Support non-US keyboard layouts jupyterlab#7579
  • Codemirror 6 Move away from KeyboardEvent.key for key bindings? codemirror/dev#146
  • Tool for mapping key and character pointed by Pete https://w3c.github.io/uievents/tools/key-event-viewer.html
  • Table of keyboard shortcuts: https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts
  • Keyboard layouts for text and office systems https://en.wikipedia.org/wiki/ISO/IEC_9995
  • Issue 11986: Document guidance for keyboard shortcuts
  • Nick: “If the user can’t control it, we’re doing it wrong.”
  • relevant docs for the new getlayout functionality in chrome: getLayoutMap() returns keyboard layout on Chrome-based browsers lumino#271
  • New enhancement proposal to add guidance on shortcuts
  • Colab still uses the keyboard shortcuts from IPython back in 2014 (with lots of users complaining).

  [Isabela] Advocates for having captions/transcriptions of meetings. If anyone knows of a way to get transcriptions, please reach out to Isabela.
  We will try recording next week meeting (with a 5-10 minutes start period without recording)

Issues needing triage

6 issues (-19 versus last week 🎉 thanks to you all who help on that front)

Agenda

• Frederic

  • JupyterLab 3.3
    Thanks to Eric for beta release
    I would like to cut the RC but missing #11963
  • Monthly Performance meeting after this one

• Jeremy

  • Drop nbclassic, depend on notebook_shim: Drop nbclassic, depend on notebook_shim jupyterlab#11894
  • Drop the dependency on ipykernel? Drop the dependency on ipykernel? jupyterlab#11958
    [Vidar] it is useful for the JupyterLab python package to have a dependency on ipykernel (low cost, high reward)
    [Paul] as notebook did
    [Nick] we could start having multiple packages: jlab-core, jlab-builder,...
    [Damián] Either way (dependency or meta packages) as long as people get a live running kernel after installing ;-)

• Trung Le

  • Completer part 2 (Update completer part 2 jupyterlab#11969)
    [Tony] Where does the output come from?
    You can customize the providers (see PR and the previous one)
    [Tony] What format are supported?
    You can bring your own doc renderer

• Isabela

  • Jupyter community call is next week! Find more information on the Jupyter Discourse

• Eric

  • Plan to open a JEP for a UI Components - early draft on https://github.com/datalayer/jupyter-react/blob/jep/jep/README.md discussed with Frédéric and Jeremy on draft JEP datalayer/jupyter-ui#10)

• Gabriel

  • Have a more consistent UX between Retro and Classic in the file manager.
    This issue comment links to a demo using checkboxes to improve accessibility.
    Looking for feedbacks

  • Short screenshare/demo
    [Nick] The best would be to able to add a column from extensions
    It will be better to get it in in JupyterLab; maybe in a 3.x release (turn off by default and revising that for 4.0)
    [Paul] Does right-click context menu just work with the checkbox selection? Yes, it should.
    [William] Do the checkboxes work on touch devices (there may not have mouse hover)? One solution is to just show the checkboxes at all times on touch devices. Gabriel confirms this behavior on his Windows laptop in tablet mode.

• Tony

  • triage meeting moved (find it on the Jupyter community calendar)

Additional discussions

• JupyterLite:

  • integration in documentation https://numpy.org PR for sympy
  • Nick and Jeremy are working to reduce the bundle size
  • lab and retro built together

• Issue triage for JupyterLab

  • Open all contents as notebooks including non .ipynb extensions #11896

  • Run cells with a specified tag #12069 (accepted)
  • timeout variable value not taking effect in notebook #12018

  [Isabela] Does an issue tagged as Needs: info is considered as triage?
  [Darian] It should be considered triage

  • Jupyter Community Building Committee Charter
  • December 2021 Jupyter Community Update
  • Keep an eye out for an upcoming blog post with a survey about JupyterCon

• JupyterLab 3.3

  • Blocking issue Opening keyboard shortcuts UI result in "destruction" of shortcut settings
    
    What to do for plugin setting that defines transformation? Should we add registration of a transformation prior to saving? Or a transformer prior to saving when registering the custom setting editor.

  [Jason G.] You may be able to treat them as sets for diffing, if it helps.

  • WIP Announcement document
    Where to publish? Discourse 👍

• Alex

  • @marthacryan, @jasongrout, and I submitted a "What's new in Jupyterlab" talk proposal to SciPy. We're also looking into submitting a tutorial proposal as well.

• Jason W

  • PR 12028: WIP changes for cell toolbar (issue 9733, Binder share link)
    • Known issue: How to watch each cell for changes to show/hide the toolbar as the user edits it (MutationObserver? Recurrent changes?)
    • Known issue: How to detect overlap for rendered Markdown?
    • Discourse discussion
      [William] Here’s what it looks like in CoCalc. It’s just above it to the left. In Colab it is above, and to the right.
      [Nick] prompt area is a whitespace wasteland
      [@jasongrout] - vs code has it floating just above the text, intersecting the cell outline, with a ... button with a lot of options.
      [Craig] Discussion for Colab - change the opacity of the toolbar depending if the mouse pointer is close or not.
      [Darian] For this V1, where the toolbar disappears if text overlaps, is having a keyboard shortcut or something to explicitly show the toolbar.
      [Frederic] May be collapsing it to a button ... overlapping the border like for the toolbar.
  • Should we continue to have the triage meeting at 10:00 AM PST on Thursdays?
    • Keeping it on the calendar at least for now, especially useful when we don't have time during the Wednesday meetings for triage
    • If we end up cancelling triage regularly, remove it from the shared Google Calendar

• Jeremy

  • Drop nbclassic PR is ready to go: Drop nbclassic, depend on notebook_shim jupyterlab#11894
  • Follow-up PR to merge: Extract markdown parser in its own plugin. jupyterlab#11971
  • Then make a new 4.0.0ax release

• @tonyfast

  • a11y meeting after this https://hackmd.io/WnaWXboXSiGoqWvev_fAvA

• @jasongrout: Update on RTC and the cell-level undo issue?

  • See Allow to disable the document-wide history tracking jupyterlab#10791 (comment)
  • See [WIP] cell-based undo manager. jupyterlab#11640

Additional discussions

• Release process PR - maintainer list (thanks to @jtpio)

• [Darian] Transition from notebook 6 to 7 - for the pre-release of v7, communicate with a blog post to highlight the coming breaking change. The blog post will direct to a place to centralize issue (probably not GitHub)
