04 March 2020 Weekly Meeting

• Introductions
• Tim
  • We should schedule meeting to discuss future releases.
  • Quick review of Extension Installer warning.
    • Extension Installer disclaimer UI jupyterlab#7967
• Steve
  • Released 2.0.0 and 1.2.7
  • Updated and released jupyter-renderers for 2.0
• Eric
  • JupyterLab as Server Extension ready for review (tests green): PR on jupyterlab, PR on jupyterlab-server
  • Quick demo for feedback of [DRAFT] [WIP] Black and White listings for the Extension Manager
• Jeremy:
  • Progress on the JupyterLab Extension Examples with @echarles and @fcollonval: https://github.com/jtpio/jupyterlab-extension-examples
  • Debugger fixes
• Alex
  • Helping update TOC to lab 2.0
  • working on a lab-git issue
  • no work on lab linter yet
• Ed (Kite)
  • Feedback on Completer changes
    • Refactor the code completer API jupyterlab#7044 (comment)
    • Proposal: JupyterLab Completer UI jupyterlab#7983
• Darian
  • Source-only version of PyPI package was missing package_data and now it is not (which is part of why Steve published 1.2.7), but it still ignores dot files unless we explicitly add them. This matters because of .yarnrc
• Saul
  • Had a fun time with Glue folks last week in NYC
    • Built a lil demo for them on building dashboards in jupyterlab https://github.com/Quansight-Labs/jupyter-widgets-takeover#jupyter-widgets-takeover
      • I can demo this
    • TLDR is blurring lines between "dashboard" and "notebook", need ways to start users in constrained environment and then move slowly to less contstrained
    • Many technical next steps to make this viable
    • Conflicting with curent Voila stack. Might be nice to chart out unified best way forward if possible
  • Working on performance improvements on switching between notebooks
    • profiled, mostly in style updates
    • going to try to do virtualized dom to update
    • strategy is to not change any API for output widget but under the hood put a later of React in the middle between two layers of Lumino widgets
    • Then use react virtualized library
    • Switching to a big notebook in a tab is slow jupyterlab#4292
    • Here is an in-progress discussion about a web standard that enables native browser virtualized scrolling for some cases: https://github.com/WICG/display-locking/
    • At one point Jason explored making a Lumino widget for virtualized scrolling. No code to show for it, but Jason would be interested in discussions around this.
• Jason
  • Helped with changelog and fallout from 2.0 and upgrading and migration challenges
  • Upgrading custom widget packages for jlab 1 and 2 turns out (through a lot of work :) to be as easy as adding ||^3 to @jupyter-widgets/base dependency version.
• Luciano
  • Helping releasing JupyterLab extensions that support JupyterLab 2.0
    • TOC for Lab 2.0 release by end of the week
    • Git for Lab 2.0 (Any ETA? I could help with release by end of the week as well)
• Max
  • starting work on jupyter-fs
    • next generation ContentsManager
    • flexibly work with multiple remote(?) "filesystems"
    • will be an official JPM project
  • Still working on icons
    • lots of optimization/speedup work
  • Starting to work on more general UI components
    • LabButton (maybe)
  • Towards the next release of jupyterlab-git
    • [WIP] Update for JupyterLab 2.0 jupyterlab-git#520
  • File icon fallback is not rendering: PDFs are missing an icon jupyterlab#7968
• Zach
  • NBClassic: add Jupyter Server / Notebook config shim layer.
  • Add a simple class to jupyterlab_server for a "transition period" that manages config shims.
  • Remove this class after transition period ends—little disruption to Jupyter Lab.
  • https://github.com/Zsailer/nbclassic/pull/7
