Add Knob and Fader console widgets (0.5.25) - #324
Merged
Conversation
New audio-console controls: - Knob: partial-arc rotary (configurable sweep up to a full circle), pointer, configurable tick scale, discrete `steps` detents, and Web MIDI learn. - Fader: vertical/horizontal mixing-console fader with a tick scale and `steps`. - MIDI learn (opt-in) with upfront `midi_cc`/`midi_channel` and localStorage persistence namespaced by the browser URL path. - Demos, reference docs, gallery entries, llms.txt, changelog, quick-ref table.

PR #324 added Knob and Fader as a gallery row with a trailing empty <td></td>, which failed test_gallery_cells_are_well_formed (only the final row may be short). Move both cards into the final Hint row so every row has exactly three well-formed cells. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Two new audio-console input widgets for
wigglystuff, released as 0.5.25.Knob— audio-panel rotary knob. Partial-arc by default (start_angle/end_angle, up to a gapless full 360° circle), with a pointer, a configurable tick scale (ticks), and discrete detents (steps) for a rotary selector.Fader— mixing-console fader (vertical or horizontal) with a configurable tick scale and the samestepsdetents.midi=True): click the button, move a hardware control, and the next control-change binds to the widget and drives its value. Bindings can be set upfront (midi_cc/midi_channel) and persist across restarts in browser localStorage, namespaced by the notebook URL path (override withmidi_key/midi_scope). Web MIDI is Chromium-only and needs a secure context.demos/knob.py/demos/fader.py, reference docs, gallery entries (README + docs),llms.txt, changelog, and the quick-reference table.Notes
MixPanel(dropped) and noSlider2Dchanges — scoped to Knob + Fader.anywidget,drawdata); no 3rd-party deps leaked into core.marimo checkon both demos.🤖 Generated with Claude Code
