Waybar

Custom module ​

To create a toggle that updates on signal, add a setting in config.jsonc like this:

{
    "custom/record": {
        "signal": 1,
        "exec": "sh -c '[ -f /tmp/waybar_record ] && echo 🔴 Recording'",
        "hide-empty-text": true,
        "escape": true
    },
}

Here depending if the file /tmp/waybar_record exists, we change the text shown on waybar.

Bellow an example of fish script that toggles the text of our module. As our signal is configured as 1, we use RT1.

#!/usr/bin/fish
touch /tmp/waybar_record
kill --signal RT1 waybar

sleep 10s

rm --force /tmp/waybar_record
kill --signal RT1 waybar
