22 Apr 2020 Weekly Meeting

• Max

  • More LabIcon docs
    • Added background section, should hopefully make the central issues clearer
    • Where should I stick these in the main jlab docs?
  • Unified API docs for the entire @jupyterlab monorepo
    • Huge improvement of the landing page for our API docs
    • Doesn't quite work right
      • The typedoc-plugin-monorepo plugin creates lots of duplicate entries
    • Easy fix: use a static landing page, like @Lumino currently does
    • Better fix: use the library mode of typedoc (currently experimental)
      • unlike now, library will allow for the API docs of each @jupyterlab package to link to one another (I think)
  • The future of LabIcon
    • I want to bring everyone onto the same page about LabIcon
    • Turns out there is in fact no single optimal way to create and use icons
    • I need a way to consume LabIcons that allows for both late binding (like our old icons-as-css-background) and dynamic repainting on theme change (like our new icons-as-inline-svg)
      • Improve performance of long lists with 1+ icons per item
      • Allow for updates of component/widget style post-render
      • (example issue) Should make a lot of complex icon usages easier to refactor for LabIcon
    • I've investigated three proposals for implementing the above
    • There's a working prototype for proposal 1: dynamically generated icon stylesheets

• Tim

  • Working on settings editor for JupyterLab.
    • Thinking about how to treat this, JSON Schema editor or pure GUI interface that hides the complexity?
      • Check VSCode Settings editor. (UI with Validation)
      • Web browsers.
      • Not IntelliJ.
      • Extension points for setting editor.

• Brian

  • Starting to pick away at tasks related to RTC.
  • Can we make the DocRegistry agnostic to the type of underlying model and remove the hard dependency on ModelDB?
  • Make DocumentRegistry independent of ModelDB jupyterlab#8235
  • The notebook uses a horribly complex ContentFactory pattern that is making it difficult to work on the notebook.
  • Kill content factory pattern in notebook widgets jupyterlab#8236

• Steve

  • nteract Data Explorer - general policy on new renderers?
    • Depricate renderers repo, these should live in the community.
    • Added an issue to Team Compass to suggest a jupyterlab-forge GitHub org for any repos that aren't considered core to JupyterLab (either JupyterLab or repos that we depend on).
  • puppeteer woes
  • Fix session context error handling
  • Cache checked links
  • Meeting to discuss federated build? [See additional discussion]

• Alex

  • My team is currently hosting a IBM workshop on JupyerLab, the new JupyterLab interns are in attendance (:tada: Thanks, Alex! This is awesome! -Zach)
  • Git extension lab 2.0 update pr has been merged, pending rc for extension release with 2.0 support

• Zach

  • Jupyter Server docs received a makeover.
    • https://jupyter-server.readthedocs.io/en/latest/index.html
  • Release Server 1.0 this week. 🎉
  • Server 2.0 (master) is planning merge the following features:
    • Kernel Providers
    • (opt-in) Authorization layer
    • (opt-in) telemetry in the server-no open PR yet.
  • Messaging on notebook repo
    • Actively maintained, maintenance-only mode, or end-of-life?
    • Darian volunteered to write a JEP about the classic notebook status.

• Jeremy

  • Update JupyterLab Demo to 2.0
    • Update to JupyterLab 2.0 jupyterlab-demo#92
  • Docs update to link to the extension example repo:
    • Add Tutorials and Cookiecutters sections to the extension dev docs jupyterlab#8254

• Jason

  • Researching the extension refactor, currently webpack module federation seems most promising
  • Fixed "Save As..." and working on fix for kernel gateways being able to restart kernels.
  • Looked into being able to take advantage of the notebook buffering input.
  • Question about coordinating merging Change JSON5 payload to JSON payload jupyterlab#8225 and Change payload parsing to accept JSON5 as raw string in JSON payload jupyterlab_server#87

• Darian

  • Should we add libgbm1 manually to handle CI breakage Install libgbm1 to fix puppeteer in tests debugger#428
  • Reviewed completer refactor and had some comments that might be worth discussing in this call Refactor Completer API jupyterlab#8080

Aditional Discussion:

• Meeting about federated build
