Todays topics[edit]

  • Meet and greet 5 minutes before meeting (audio testing).

Octave 6.3.0[edit]


  • Instead of an in-person conference, meet up virtually.
  • Ideas for code-sprint?
    • Improve test coverage
    • That could include automated tests for GUI features ("expect", Qt test classes, set OCTAVE_SHOW_GUI_MESSAGES to 1 to display signals with missing connections, ...). Does anyone have experience with this?


  • Make widgets more modular
    • remove connections to parents (or parents of parents,...)
    • Only pass settings objects (instead of base qwidget) to widgets?
  • Add widgets for:
    • displaying call stack. Select function in stack for appropriate dbup or dbdown command.
    • displaying result to an expression. Similar to debugger (watcher, ...)
  • User expectations for evaluation code from the editor ("Evaluate selection") or the variable editor ("plot") while there is still pending input on the command line?


  • Add feature to temporarily disable breakpoints
  • Check syntax for breakpoints in subfunctions, local functions, private functions, methods, ... (dbstatus). See: Identifiers for breakpoints


  • Current version is not Matlab-compatible nor correct in some circumstances.
  • Rik is currently implementing a replacement.

IRC channel on Freenode is down?[edit]

  • Replacement on libera?
  • jwe will probably post something on discourse.
  • See: IRC channel for Octave (on Discourse).

Previous topics[edit]

The following items were not discussed. Just some links to progress on those items are displayed.


  • General question about the acceptance.
    • We like it.
  • Continue to no longer actively advertise the mailing-lists.

GitHub Actions[edit]

QScintilla signal/slot problem[edit]

  • Bug #60469
  • On MS Windows only for QScintilla the "safer" signal/slot changes seem to not work.
    • Revert it until the problem is identified.

Ideas for next meeting[edit]

  • Octave 6.3 released
  • User expectations for "Evaluate selection"
