Agenda

Background on 8.0
high-level goals
summary of current state of 8.0 release
triage of current 8.0 issues
discussion of timeline
Should we publish widgetsnbextension 4, cutting out the notebook dependency, before ipywidgets 8? See version 8.0.0 seems not working with Jupyter Lab 2.0 ipywidgets#2840 (comment) and ipympl when jupyter and ipython kernel are in different conda environment matplotlib/ipympl#34
Meetings moving forward

Attendees:
@jasongrout, @vidartf, @maartenbreddels, @ianhi, @ibdafna, @jtpio, @marimeireles

ian
- What is advice for people who want blocking widgets
  - (SO + issue)
  - 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? Add github action for releasing 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? Unify cookiecutters? #4
Maarten
- Saving widget state: Feature: always save state of widgets, and only those required ipywidgets#3114
Discussion
- ipywidgets contrib
  - Perhaps open a repo or new github org. Things are merged basically automatically, with very minimal vetting.

Attendees: @jasongrout, @SylvainCorlay, @ianhi, @jtpio

Jason
- 8.0.0a4 (supporting jlab 3) was released 22 Feb
- Traitlets 4 vs 5: Traitlets 4 vs 5 changes defaults in message spec ipywidgets#3110 - Sylvain looking into it.
Ian
- Making 8.0 happen? (We're going to keep plugging away at it, no firm timeline, dependent on how much work people put into the issues and PRs on the milestone)
- New Issue Labels? Proposal for new Issue Labels ipywidgets#3161
  - Yes
Jeremy
- Initial steps for a widget examples repo: Bootstrap structure for a widget examples repo ianhi/custom-ipywidget-howto#13
  - Plan to move to jupyter widgets organization as it gets polished
- Update to TypeScript 4.2? Should this go in before 8.0? Update to TypeScript 4.3 ipywidgets#3162
  - Yes

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.

29 June 2021

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
- Async/concurrent cell execution ipython/ipykernel#696
- There is a pattern to force "synchronous" running of successive cells with await __task__()

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

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 Select: Do not force a selection if there is currently no selection and the options list changes ipywidgets#3284
- Doc fixing, fix "process.env is undefined" issue which prevented the HTMLManager to render widgets Fix docs's "process is not defined" issue ipywidgets#3283
- widgetsnbextension: Throw an exception if the widget fails to render, this allows the Notebook to fallback on other mimetypes repr Widgetsnbextension: throw error on failure to render ipywidgets#3280 (should be tested with current Notebook version/should do a Notebook version check in widgetsnbextension?)
Jeremy:
- rebased Itay's PR: Add dragging behaviour properties to sliders ipywidgets#2834
Triage for 8.0:
- Are there any issues that will need a PR?
  - #2762
  - #3247
- Are there any unassigned PRs?
- Any assistance needed on assigned PRs?

#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:
- PR to update to 8.0.0a6: Release 8.0.0a6 conda-forge/ipywidgets-feedstock#71
- Follow-up to remove the Python 3.10 upper bound: Remove Python 3.10 upper bound conda-forge/ipywidgets-feedstock#72

Hold sync during set_state Hold sync during set_state + fix selection widgets flakiness ipywidgets#3271
Jupyter Releaser:
- Started by David in Prepare for Jupyter Releaser 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.

  - We think this is probably backwards compatible. Jason is opening an issue in Lumino about this general pattern.
Review of PR from Trung Le Duc (Error widgets)
- ErrorWidget as fallback when widgets models or views fail - Following up ipywidgets#3304
  - There are a few outstanding questions in the PR review.
