Configuring

The main config file is located in /etc/xdg/swaync/config.json. Copy it over to your .config/swaync/ folder to customize without needing root access. See swaync(1) man page for more information

To reload the config, you'll need to run swaync-client --reload-config

The main CSS style file is located in /etc/xdg/swaync/style.css. Copy it over to your ~/.config/swaync/ folder to customize without needing root access.

Scripting

Scripting rules and logic:

. Only one script can be fired per notification . Each script requires exec and at least one of the other properties . All listed properties must match the notification for the script to be ran . If any of the propeties doesn't match, the script will be skipped . If a notification doesn't include one of the properties, that property will be skipped

More information can be found in the swaync(5) man page

Notification information can be printed into a terminal by running G_MESSAGES_DEBUG=all swaync (when a notification appears).

Config properties:

{
  "scripts": {
    "example-script": {
      "exec": "Your shell command or script here...",
      "app-name": "Notification app-name Regex",
      "summary": "Notification summary Regex",
      "body": "Notification body Regex",
      "urgency": "Low or Normal or Critical",
      "category": "Notification category Regex"
    }
  }
  other non scripting properties...
}

config.json example:

{
  "scripts": {
    // This script will only run when Spotify sends a notification containing
    // that exact summary and body
    "example-script": {
      "exec": "~/.config/swaync/myRickRollScript.sh",
      "app-name": "Spotify"
      "summary": "Never Gonna Give You Up",
      "body": "Rick Astley - Whenever You Need Somebody"
    }
  }
  other non scripting properties...
}

Disable scripting

To completely disable scripting, the project needs to be built like so:

meson build -Dscripting=false
ninja -C build
meson install -C build

Waybar Example

This example requires NotoSansMono Nerd Font to get the icons looking right

Waybar config

  "custom/notification": {
    "tooltip": false,
    "format": "{icon}",
    "format-icons": {
      "notification": "<span foreground='red'><sup></sup></span>",
      "none": "",
      "dnd-notification": "<span foreground='red'><sup></sup></span>",
      "dnd-none": ""
    },
    "return-type": "json",
    "exec-if": "which swaync-client",
    "exec": "swaync-client -swb",
    "on-click": "swaync-client -t -sw",
    "on-click-right": "swaync-client -d -sw",
    "escape": true
  },

Waybar css file

#custom-notification {
  font-family: "NotoSansMono Nerd Font";
}

Alternatively, the number of notifications can be shown by adding {} anywhere in the format field in the Waybar config

  "custom/notification": {
    "format": "{} {icon}",
    ...
  },

Screenshots

I wonder how this would look with some blur 🤔
