17 June 2020 Weekly Meeting

• Mehmet: present Galata (JupyterLab UI Testing Framework)

• Eric

  • JupyterLab Server as Server Extension jupyterlab/79 and jupyterlab-server/7416 updated and green - Depends on a few jupyter_server PR/issues (Confusion between extension_name and module name, Existing Classical Server Extension Support...)
  • Race Condition with Slow Restarting Kernels: Opened PR jupyterlab/8562 which adds terminating state in the Kernel Status Indicator (with new method on ISessionContext) and blocks cell run if Kernel is terminating - Will update PR with cell run queuing with toast in a second iteration.

• Saul

  • Future of JupyterLab Vim
    • JupyterLab already has Vim key bindings for text editing, this extends it to allow command mode in the notebook
    • Huge number of stars and users!
    • Current version unmaintained, fork is updated for most recent jlab https://github.com/axelfahy/jupyterlab-vim
    • We have a client who uses this
    • Currently uses some hacks: https://github.com/axelfahy/jupyterlab-vim/blob/c4e43f940ef4be4c961608b6192412d2f3a33d1f/src/index.ts#L61
    • Going to look into either bringing into core or adding hooks in core to make less hacky
    • Any thoughts from others on whether I should explore moving this into core?
    • Conclusions:
      • We don't wanna move this into core
      • There is support for making it less hacky, by exposing ways to override codemirror more easily

• Athan

  • JupyterLab ToC context menus: Add context menus to sections containing runnable code cells jupyterlab-toc#141

• Tim

  • Cal Poly interns started this week. Expect to see them in here from time to time.
    • Snippets UI
    • Tabular Data editor
    • JupyterLab Viola Extension (customizeable dashboards)

• Jason

  • Extension system refactor

• Brian

  • Canceling meetings on Juneteenth 6/19 to reflect on systemic racism and injustice.
  • Aiming to get an improved document oriented UX into JLab for 3.0.
    • Proposal: master plan for single document mode jupyterlab#8567
  • Starting to work on task breakdown for overall RTC work

• Additional Discussion

  • Minor release still feasible?
  • Release timeline for 3.0
  • Priorities for 3.0
  • Triage for 3.0
  • Dropping python 3.5 and 3.6 support

@saulshanabrook is there anywhere that I can follow any changes related to vim mode in jupyterlab? I'm interested both as a vim bindings user and as a creator of two small extensions that add functionality to vim mode.

@ianhi I have opened jupyterlab/jupyterlab#8592 to further discuss the VIM mode in cell editors. Happy to get your feedbacks there.
