Headless service that follows niri msg -j event-stream and enables notification Do Not Disturb via the host IPC (notification-dnd-set) while at least one screencast is active, restoring it afterwards. Side effects: spawns a persistent shell retry loop around `niri msg -j event-stream`, runs `niri msg -j casts` / `niri msg version` and `noctalia msg notification-dnd-*` on demand. No network access, no filesystem writes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
ShareDND
Automatic Do Not Disturb while the screen is being shared.
When the first screencast starts (any app sharing via the portal — Discord,
OBS, browsers, niri msg action set-dynamic-cast-*, ...), notification DND is
enabled. When the last screencast stops, notifications come back.
How it works
- A headless service follows
niri msg -j event-streamand reacts toCastsChanged/CastStartedOrChanged/CastStoppedevents — no polling. - On every cast event it re-queries
niri msg -j castsas the authoritative state, so missed or reordered events cannot desync it. The stream is wrapped in a shell retry loop and resends full state on reconnect. - DND is toggled through the host IPC (
noctalia msg notification-dnd-set), so the usual OSD feedback appears.
Ownership rules
- If DND was already on before sharing started, the plugin leaves it on after sharing ends (it never took ownership). The "Always disable DND after sharing" setting overrides this.
- If DND was enabled manually during sharing while the plugin owned it, it will still be turned off when sharing ends (the plugin cannot tell the difference).
Settings
- Only active streams — count only casts with
is_active: true. Off by default: any open screencast session (even paused or showing nothing) keeps DND on. - Always disable DND after sharing — force DND off when sharing ends, regardless of its state before sharing started.
Requirements & limitations
- Requires niri (detection is niri IPC; on other compositors the plugin is inert and shows a warning at startup).
- There is no plugin-disable hook in the host: if you disable the plugin mid-share while it owns DND, DND stays on — toggle it manually.
