Keyboard backlight support for T2 macbooks.

[satyapraneet63]

I am using a 2019 13" MacBook Air. My mac buttons are working as expected mostly, I see xf86 keybinds for most of the buttons, but not the keyboard backlight. I have added them to the ~/.config/hypr/bindings.conf for myself.

bind = , XF86KbdBrightnessDown, exec, brightnessctl -d apple::kbd_backlight set 10%- && notify-send "Keyboard Brightness" "$(brightnessctl -d apple::kbd_backlight | grep -oP '\(\K[0-9]+(?=%\))')%"

bind = , XF86KbdBrightnessUp, exec, brightnessctl -d apple::kbd_backlight set +10% && notify-send "Keyboard Brightness" "$(brightnessctl -d apple::kbd_backlight | grep -oP '\(\K[0-9]+(?=%\))')%"

I have tried to integrate the swayosd-client custom message, but am failing miserably. I could use some help and maybe have this added for the T2 macs since they are being supported out of the box. Temporarily using the notify-send as a bandaid. Most of the features for mac are running smoothly. My respect to the maintainers.

I am tempted to open a PR, but that would be presumptuous since I only have a stopgap solution. Hoping to find a more elegant one through discussion.
I have opened an enhancement issue here: #2291 (comment)

#!/bin/bash
# change brightness
sudo brightnessctl --device=apple::kbd_backlight set "$1"
# get percentage
perc=$(( $(brightnessctl -d apple::kbd_backlight get) * 100 / $(brightnessctl -d apple::kbd_backlight max) ))
# show OSD
swayosd-client --custom-message="Keyboard Brightness: $perc%"

This script can be used in terminal, but I am unable to execute it in the bindings.conf

for those comment blocks its better if you use fenced code blocks

Thanks. I'll use them next time

#1779
This issue was brought up here. I used his code block in ~/.config/hypr/bindingd.conf

had to change to apple::kbs_backlight for my device

$keysswayosd = $osdclient --custom-progress=$(awk "BEGIN {print $(brightnessctl --device=apple::kbd_backlight get)/255}") --custom-icon=input-keyboard
bindeld = ,XF86KbdBrightnessDown, Keyboard Brightness down, exec, brightnessctl --device=apple::kbd_backlight set 10%- && $keysswayosd
bindeld = ,XF86KbdBrightnessUp, Keyboard Brightness up, exec, brightnessctl --device=apple::kbd_backlight set +10% && $keysswayosd
bindeld = SHIFT, XF86KbdBrightnessDown, Keyboard Brightness max, exec, brightnessctl --device=apple::kbd_backlight set 0% && $keysswayosd
bindeld = SHIFT, XF86KbdBrightnessUp, Keyboard Brightness max, exec, brightnessctl --device=apple::kbd_backlight set 100% && $keysswayosd
bindeld = ALT, XF86KbdBrightnessDown, Keyboard Brightness down precise, exec, brightnessctl --device=apple::kbd_backlight set 1%- && $keysswayosd
bindeld = ALT, XF86KbdBrightnessUp, Keyboard Brightness up precise, exec, brightnessctl --device=apple::kbd_backlight set +1% && $keysswayosd
