  • ian

    • What is advice for people who want blocking widgets
      • See https://ipywidgets.readthedocs.io/en/stable/examples/Widget%20Asynchronous.html
      • Perhaps we change the kernel protocol to allow the kernel to process comm messages even if it is not idle (for example, if a cell has an await)?
      • We could ship the utility functions in the widget async docs, and make some more examples using them. Especially with dependencies on modern Python + ipykernel, this is more feasiable than before.
      • Make async waiting easier to use - make docs more approachable, ship utility function (ian make issue)
    • Automated releasing secrets? who can add them? jupyter-widgets/jupyterlab-sidecar#62
      • We could release based on setting a tag. That makes it very easy, maybe too easy?
      • We could release based on drafting a GitHub release.
      • Ian and Jason getting together to explore this.
    • [not discussed] unify cookiecutter? #4

  • Maarten

  • Discussion

    • ipywidgets contrib
      • Perhaps open a repo or new github org. Things are merged basically automatically, with very minimal vetting.

What is the status of pythreejs? It is now a prebuilt extension compatible with JupyterLab 3.

Meeting times: We decided to move to a weekly meeting schedule to help development momentum, and re-evaluate the time to better accommodate those that are actually coming to the meetings. Since we're in the middle of a confusing time where some of us are on Daylight Saving time and others aren't, we'll keep the 7am Pacific Daylight Time meeting for Thursday, 25 Mar. Jason will send out a poll for a new meeting time for a weekly meeting for the following week.

Attendees: @jasongrout, @davidbrochart, @ilyabo, @ibdafna

  • Welcome Itay (@ibdafna) as an ipywidgets maintainer!
  • Scipy 2021 tutorial is in two weeks, based on ipywidgets 7.6.3, JupyterLab 3.0 (Matt Craig, Itay Dafna, Mariana, Martin, Youness)
    • This year emphasizing additional widget libraries, like ipycanvas, ipycytoscape, ipydatagrid, etc.
  • 8.0a5 is out: lots of package upgrades, so please test third-party widgets
  • @ilyabo, @davidbrochart: Async widgets: we have a modified kernel now that enables async processing of widgets.
    • Each cell is launched as an async function and is launched as a task. You can run several cells concurrently. If there is purely synchronous code, it runs as normal. Essentially the top-level await is converted to an await inside an async function, so await returns control to the event loop.
    • https://github.com/davidbrochart/akernel
    • ipython/ipykernel#696
    • There is a pattern to force "synchronous" running of successive cells with await __task__()

13 July 2021

Attendees: @jasongrout, @vidartf, @ibdafna

  • @ibdafna: ipywidgets tutorial report (Monday morning at Scipy)

    • We cleaned up the tutorial repo, updated the binder, etc.
      • Didn't show some of Maarten's widgets because they weren't working
    • Went well. Generated buzz on Twitter. It was a new audience, with many people exposed to ipywidgets for the first time. About 100 attendees.
    • Need short introduction to decorators
    • The styling/layout section was a bit long. Instead, just give a few examples, then jump in with examples and day-to-day issues people will face.
    • We'll continue refreshing and rotating the list of ipywidgets libraries we are showing each year.
    • The online platform worked well, the platform worked pretty well. The platform "Q&A" section was a bit awkward to use.
    • Lots of questions, especially compared to last year.

  • ipywidgets 8.0 triage

    • Went through recent PRs, reviewed and merged some, and assigned out others.

  • https://codepath.org/ - interesting mentoring opportunity

Attendees: @vidartf, @jtpio, @ianhi, @ibdafna

Triage for 8.0

  • Add dragging behaviour properties to sliders: #2834

    • Rebase + rename to american spelling
    • Merge and do a final review after having it in alpha

  • If we include #2762, we should also consider #2605

    • Current proposal: Add three new promises: attached, layedOut, shown. Then deprecate displayed, and have that resolve at the same time as attached for now (retaining its current behavior). This will allow for third-party libraries to update on their own time, but still resolve the ambiguity.

Attendees: @jtpio, @martinRenou, @vidartf, @jasongrout, @ibdafna

  • Martin:

    • Select widget: prevent arbitrary selection if there is currently no selection and the option list changes jupyter-widgets/ipywidgets#3284
    • Doc fixing, fix "process.env is undefined" issue which prevented the HTMLManager to render widgets jupyter-widgets/ipywidgets#3283
    • widgetsnbextension: Throw an exception if the widget fails to render, this allows the Notebook to fallback on other mimetypes repr jupyter-widgets/ipywidgets#3280 (should be tested with current Notebook version/should do a Notebook version check in widgetsnbextension?)

  • Jeremy:

  • Triage for 8.0:

    • Are there any issues that will need a PR?
    • Are there any unassigned PRs?
    • Any assistance needed on assigned PRs?

Attendees: @martinRenou, @vidartf, @jasongrout, @SylvainCorlay

  • #3280

    • Can we confidently make a minor release of widgetnbextension? Probably best to branch from last

  • #3021

    • This PR does not change the current logic for ipywidgets. It is adding a new Comm entry point for Voila to fetch all widgets models at once.

  • 8.0.0a6 on conda:

  • Bug fix jupyter-widgets/ipywidgets#3296

  • Fech all widgets in one go on the control channel: jupyter-widgets/ipywidgets#3021

  • Hold sync during set_state jupyter-widgets/ipywidgets#3271

  • Jupyter Releaser:

    • Started by David in jupyter-widgets/ipywidgets#3298
    • How do we want to version the packages?
    • Do we want to be able to release packages indepedently? ipywidgets, jupyterlab_widgets, widgetsnbextension -> Yes
    • Currently bumping versions is like a complex decision tree
      • We could start by documenting how versions are bumped. For example how to decide whether this is a minor version and what updating a given package means for the other packages that depend on it.
      • The releaser takes a spec as input. So we would have to encode the bump we would like to do, and let the bump script update the right packages.
      • There is also the protocol version as another version to consider. This one could be versioned manually.

  • Jason: upgrading to TypeScript 4.5 has incompatibilities with older JupyterLab versions, so we hold off upgrading it in the RC.
  • Discussed Maarten's front-end sync PR. Sylvain and Itay will meet on Dec 22nd to run a a few final tests and, if not issues are found, merge and release RC0 🎉
