Waybar-Light-Controls (Hyprland)

Waybar integration for hyprsunset, featuring configurable gamma and temperature limits with persistent settings saved between sessions.
This behavior can alternatively be achieved using direct Waybar actions, such as:

hyprctl hyprsunset gamma +10   # on-scroll-up  
hyprctl hyprsunset gamma -10   # on-scroll-down

You can configure the brightness and blue light filter by scrolling through the icons.

Installation

git clone https://github.com/MatheusBrunheroto/Waybar-Light-Controls.git
cd Waybar-Light-Controls
chmod +x install.sh
./install.sh

The install.sh script will:

• Create directories under ~/.config/hypr and ~/.config/waybar.
• If the scripts directory does not exist, it will be created along with a waybar-light-controls subdirectory.
• Move the repository files into their respective configuration directories.

Waybar Configuration

Add the following blocks to your Waybar configuration file under the desired section (modules-left, modules-center, or modules-right):

"custom/light":{
        "format": "{icon} ",
        "format-source": "{icon} ",
        "tooltip": false,
        "format-icons": ["●"],
        "on-scroll-up": "bash ~/.config/waybar/scripts/waybar-light-controls/light_control.sh up",
        "on-scroll-down": "bash ~/.config/waybar/scripts/waybar-light-controls/light_control.sh down",
},
"custom/temperature":{
        "format": "{icon} ",
        "format-source": "{icon} ",
        "tooltip": false,
        "format-icons": ["○"],
        "on-scroll-up": "bash ~/.config/waybar/scripts/waybar-light-controls/temperature_control.sh up",
        "on-scroll-down": "bash ~/.config/waybar/scripts/waybar-light-controls/temperature_control.sh down",
},

After editing your config, restart Waybar or reload it:

pkill waybar && waybar &

Initialization on Startup

To ensure the system initializes with the previously saved gamma and temperature settings, add the following line to your ~/.config/hypr/hyprland.lua file under hl.on("hyprland.start", function ():

hl.exec_cmd("~/.config/hypr/scripts/waybar-light-controls/hyprsunset_init.sh")

This command will restore the values stored in default_light.conf and default_temperature.conf during startup.
