tauler-notify

A desktop notification data source for the tauler status bar.

It is a real freedesktop notification daemon: it claims org.freedesktop.Notifications on the session bus, so applications send it notifications the usual way. Instead of drawing popups it emits the current notification list on stdout, leaving the presentation entirely to your layout.

Because it takes the D-Bus name, it replaces daemons like dunst or mako rather than running alongside them.

Install

cargo install tauler-notify

Use from a layout

<Module bin="/home/you/.cargo/bin/tauler-notify">
  {(data, events) =>
    data?.notifications?.map(n => (
      <div class="flex flex-col px-2 py-1" on_click={events.dismiss({ id: n.id })}>
        <span class="text-[11px] opacity-60">{n.app_name}</span>
        <span class="text-[13px] text-white">{n.summary}</span>
      </div>
    ))
  }
</Module>

Protocol

Emitted on stdout, one object per line, whenever the set of live notifications changes:

{
  "notifications": [
    { "id": 1, "app_name": "Slack", "summary": "New message", "body": "…", "urgency": 1 }
  ]
}

urgency follows the freedesktop scale: 0 low, 1 normal, 2 critical.

Accepted on stdin:

Notifications expire on their own timeout (the spec's default of 5 s when the client asks for the server default, never for a timeout of 0).

When stdin closes the parent bar is gone, so the daemon exits rather than lingering and holding the D-Bus name.
