swaync -- SwayNotificationCenter
Candy Properties

| Install files | charly.yml, task:, swaync-wrapper, config.json, style.css |
Packages
SwayNotificationCenter(RPM) -- providesswaync,swaync-client
Service
Runs as a supervisord service (priority 14, startsecs=2) via swaync-wrapper which waits for the Wayland socket before starting. The wrapper uses pkill -9 -x swaync (exact name match) to kill any stale instance before exec, preventing D-Bus name conflicts on restart. startsecs=2 gives swaync time to claim the D-Bus name before supervisord declares it running. Priority 14 ensures swaync starts after the compositor (10-12) but before waybar (15), so the notification indicator module is ready.
D-Bus Auto-Activation Fix
The task: removes D-Bus auto-activation service files (org.erikreider.swaync.service, org.erikreider.swaync.cc.service) at build time. Without this fix, D-Bus spawns a competing swaync instance when waybar's swaync-client -swb queries the notification service ~2 seconds after startup. The SystemdService= directive in those files is intended to delegate to systemd, but since containers use supervisord (not systemd as PID 1), D-Bus falls back to Exec=/usr/bin/swaync, creating a second instance that steals the D-Bus bus name from the supervisord-managed one — causing the supervisord instance to exit with FATAL status.
Configuration
config.json (~/.config/swaync/config.json)
- Notification panel on right side, overlay layer
- Widgets: inhibitors, title, dnd (Do Not Disturb), mpris (media), notifications
- Timeouts: 6s normal, 4s low, 0s critical (stays visible)
- Control center: 420px wide, top-right corner
style.css (~/.config/swaync/style.css)
Catppuccin Mocha theme matching waybar:
- Color-coded notification priorities: blue (normal), red (critical), gray (low)
- MPRIS media player widget
- DnD toggle switch
- Rounded corners, semi-transparent backgrounds
Waybar Integration
The waybar custom/notification module displays a notification bell icon using swaync-client:
- Click: toggle notification panel (
swaync-client -t) - Right-click: toggle Do Not Disturb (
swaync-client -d) - Icons use Nerd Font symbols (from
desktop-fontscandy)
Compositor Compatibility
Works with any wlroots compositor via wlr-layer-shell protocol:
- sway -- replaces mako (mako removed from sway layer)
- labwc -- first notification daemon (none was previously included)
Testing Notifications
Send and verify notifications declaratively with the dbus: check verb (served
out-of-process by candy/plugin-dbus, driving the session bus with gdbus — no
shell quoting issues), run with charly check live <image> --filter dbus:
notify-test:
check: a desktop notification is delivered
dbus: notify
context: [deploy]
text: Title
description: Body text
notifications-registered:
check: swaync is receiving notifications
dbus: list
context: [deploy]
stdout:
contains: Notifications
Host-side alternatives:
# charly cmd with completion notification (gdbus, host-side)
charly cmd <image> "sleep 2 && echo done"
# Low-level: notify-send (requires libnotify layer)
charly cmd <image> "notify-send 'Title' 'Body text'" --no-notify
# swaync-client operations
charly cmd <image> "swaync-client -c" # notification count
charly cmd <image> "swaync-client -C" # clear all
charly cmd <image> "swaync-client -t" # toggle panel
charly cmd <image> "swaync-client -d" # toggle DnD

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.

CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).
