Think about: What exciting things did you accomplish? What loose ends remain? Big questions? Big ideas?

  • File dialog scrunches / truncates file names
    • The file dialog comes from @jupyterlab/filebrowser
    • It’s the same as the file browser on the left panel
      • The file browser on the left panel works perfectly!
    • We’re just using in a different context to display it as a modal
      • Maybe the context is the problem, and the file browser in the left panel depends on some CSS from a parent element to look correct?
    • Reproduction is inconsistent 🤯 🫠
      • Some people/browsers see ellipses, some people don’t
        • Sanjay sees ellipses in Firefox, no ellipses in Chrome
      • Some people see truncation, some people don’t
        • It doesn’t seem like truncation depends on the browser
      • It seems to have nothing to do with browser model or browser version
        • Matt (Ubuntu) was using Firefox 137, and it reproduced
        • Kristin (Mac) was using Firefox 138, and it did not reproduce
        • Matt upgraded to Firefox 138, and it did reproduce
        • Martin (Fedora) was using latest Firefox, and it did not reproduce
        • Sanjay (Mac) reproduced in Chrome & Firefox 137
        • Arjun (Mac) was using Chrome, unable to reproduce fully
          • Decreasing width of the file browser hides modified dates
          • But the filenames never get scrunched
        • Felipe (Mac) was using Safari & Firefox, and it reproduced
    • Fiddling around with styles sometimes helps, but hasn’t yet yielded a full solution where the dialog works exactly like the file browser in the left panel.
      • TODO: Sanjay to fill out some of the things he’s tried!
    • DID SANJAY (’s drunk AI companion) FIX IT ?!?!?!?!?!
      • How? … TODO …
        • Sanjay modified packages/base/source/style/dialog.css
          • In the main branch, there’s basically nothing in that file
  • Were able to fix 🎉:
    • Symbology panel: color steps are not recovered properly after setting graduated radius - https://github.com/geojupyter/jupytergis/issues/694 with https://github.com/geojupyter/jupytergis/pull/700
