GitHub - skorotkiewicz/rudo: A small, elegant dock for Wayland

A small, elegant dock for Wayland.

rudo is built for a clean desktop: pinned apps, live running windows, gentle autohide, and simple user configuration. It is designed to feel at home on niri, while still working with other Wayland compositors that expose the right protocols.

Features

Wayland-first dock UI with GTK4 + layer-shell
Persistent pinned apps
Running window tracking
Launch feedback to prevent double-click spam
Badge notifications — unread counts from apps (Discord, Telegram, etc.)
Configurable menu system — power menu, custom actions, confirmations
Output-based grouping — group and order windows by monitor/screen
Optional autohide with hover-to-reveal
User theming via CSS
User behavior settings via JSON

Compositor Support

niri: best experience, using NIRI_SOCKET integration
Other Wayland compositors: works through wlr-foreign-toplevel-management when available

Feature Availability by Backend

Feature	niri	wlr-foreign-toplevel
Window tracking	✅ Full	✅ Full
Activation/close	✅ Full	✅ Full
Badge notifications	❌ Not yet	⚠️ Limited*

* Badge notifications depend on compositor-specific protocol extensions. Most compositors don't currently provide badge counts through the standard protocol.

Build

cargo build --release

Or with just:

just build

Run

cargo run --release

Or:

just run

Install

From AUR (Arch Linux)

For Arch Linux users, rudo is available in the AUR as rudo-bin:

yay -S rudo-bin
# or
paru -S rudo-bin

This installs the pre-built binary. No compilation needed.

Configuration

rudo stores its user files in ~/.config/rudo/.

pins.json: pinned applications
settings.json: behavior settings
style.css: visual overrides

Default settings.json:

{
  "autohide": {
    "enabled": true,
    "delay_secs": 3
  },
  "show_pin_button": true,
  "icon_size": 24,
  "position": "bottom",
  "animation_duration_ms": 220,
  "menu": {
    "enabled": true,
    "icon": "system-lock-screen-symbolic",
    "position": "end",
    "items": [
      {"label": "Lock", "icon": "system-lock-screen-symbolic", "command": "swaylock -f", "confirm": false},
      {"label": "Logout", "icon": "system-log-out-symbolic", "command": "loginctl terminate-user $USER", "confirm": true},
      {"label": "Restart", "icon": "system-restart-symbolic", "command": "systemctl reboot", "confirm": true},
      {"label": "Shutdown", "icon": "system-shutdown-symbolic", "command": "systemctl poweroff", "confirm": true}
    ]
  }
}

position: "bottom", "top", "left", "right" (requires restart)
icon_size: Size in pixels (default: 24)
animation_duration_ms: Show/hide animation in milliseconds (default: 220)

Menu System

Configure a power menu or custom actions via the menu section:

enabled: Show/hide the menu button
icon: Icon name for the menu button (default: system-lock-screen-symbolic)
position: "start" (before pins) or "end" (after running apps)
items: Array of menu items with label, command, optional icon, and confirm flag

Set confirm: true to show a confirmation dialog before executing destructive commands.

Badge Notifications

When supported by your compositor, rudo displays unread notification counts (badges) on dock items from apps like Discord, Telegram, etc. Badge counts are aggregated across all windows of the same app.

Zero-count badges are automatically hidden
Counts above 99 display as "99+"
Red badge with white text for visibility

style.css is loaded on every start after the built-in theme, so you can override the dock without rebuilding.

Autostart (niri)

Add to your niri config:

// ~/.config/niri/config.kdl
spawn-at-startup "rudo"

Development

just fmt
just check

Status

rudo is intentionally small. The codebase is structured to stay easy to change as more dock behavior is added over time.
