  • https://github.com/ScottLogic/kdb-studio-2
  • https://github.com/jshinonome/vscode-q
• (5 min) For vscode-q / Kdb Studio 2 running as VS Code plugins, how to support Authentication plugin API to allow support for Kerberos, etc.?
  • add support for auth method extension points jshinonome/vscode-q#40 (comment)
  • Clarified that there is no need to change node-q.js.
    • Just want to generate a token which will be passed in the password field of the regular handshake.
  • Proposed solution is that vscode-q plugin would probe for other plugins(!).
    • A bit surprising that plugins aren't sandboxed from each other, but does make life easier.
• (5 mins) An introduction to KDB Studio 2 Prototype KDB Studio 2 Prototype #51 - @ColinEberhardt
  • Apparently not too much code required thus far!
    • Leveraging of: Monaco (editor behind VS-Code) and Electron (for distribution)
  • Additional functionality required to make it a viable replacement for Kdb Studio Classic:
    • Excel Export
    • Server List Export
    • Hot Keys
• (5 mins) Is there room for Kdb Studio 2 and VS-Code plugin?
  • Mention of Kx Dashboards & Kx Analyst having overlapping functionality but different target audiences.
  • @dzmipt believes he will continue enhancing Kdb Studio Classic for a while because:
    • More familiar with Java and existing code base.
    • More feature rich for now.
    • Roadmap ncludes: scatter charts, uploading results to server, word wrap
    • Also knows of users kdb who are attached to Sublime / IntelliJ.
  • vscode-q goings-on
    • Language Server extension that analyzes the source code.
      • Would provide autocomplete functionality.
      • Very early days. Not pushed for public consumption yet.
    • Has constructed a simple parser for q, but probably incomplete.
    • Can't use any existing parser since he needs more than just a stream of tokens:
      • Information needed by VS-Code: start line, start position, end line, end position
    • Might benefit from collaboration with those who've studied the q grammar quite closely.
• (5 min) qPython updates?
  • Probable name change to qPython3 to release on PyPi.
  • Dropped Python 2.x support.
  • fastutil.pyx 64-bit changes undergoing testing within Morgan Stanley.
• (5 min) Unique Set Size updates?
  • Pull request is up: add psutil (and util) #52
  • Only supports Linux.
    • /proc is non-POSIX, so not available on MacOS X.
    • Happy to accept Pull Requests for wider OS supprt.
  • Needs a better understanding of dep.q to load a companion util.q file
• (5 min) AOB, Q&A, Adjourn.
  • @adavies42 Is working on a native unzip for q.
    • Could take advantage of secondary threads.
  • FINOS All Community Call and OSSF CFP coming up.
