Add sync support to gsettings background path

[PrincParshia]

I have made this shell code that syncs hyprland background with gsettings background path.

-> paper.sh

#!/bin/bash

BACKEND="Hyprpaper" # ofcourse :)
# $BACKGROUND must be bound in Hyprpaper!
BACKGROUND="$HOME/.background"
DIR="$HOME/.config/hypr/scripts/paper"

uri() {
	if gsettings get org.gnome.desktop.interface color-scheme | grep -q "dark"; then
		echo "picture-uri-dark"
	else
		echo "picture-uri"
	fi
}

reload() {
	file=$(gsettings get org.gnome.desktop.background "$(uri)" | sed -E "s/^'file:\/\/|'\$//g")
	cp "$file" "$BACKGROUND"
	hyprctl hyprpaper wallpaper ",$BACKGROUND" > /dev/null 2>&1 &
}

daemon() {
	if [[ -n $(pgrep -f "paper-monitor") ]]; then
		echo "[LOG] Daemon already running!"
	else
		setsid "$DIR/paper --monitor" "$(uri)" &
		setsid "$DIR/paper --monitor-scheme" &
	fi
}


usage() {
	cat <<EOF
[LOG] Welcome to paper!
Usage: paper [arg [...]].

Arguments:
--help    |-?   |help    -| Show this help message

EOF
}

case "$1" in
	--reload|-r|reload)
		reload
		;;
	--uri|-uri|uri)
		uri
		;;
	--backend|-b|backend)
		echo "$BACKEND"
		;;
	"")
		daemon

	*)
		usage
		;;
esac

-> paper --monitor.sh

#!/bin/bash

DIR="$HOME/.config/hypr/scripts/paper"

monitor() {
	local current="$1"
	gsettings monitor org.gnome.desktop.background "$current" | while read -r; do
		"$DIR/paper" --reload
	done
}

monitor "$1"

-> paper --monitor-scheme.sh

#!/bin/bash

DIR="$HOME/.config/hypr/scripts/paper"

monitorScheme() {
	gsettings monitor org.gnome.desktop.interface color-scheme | while read -r; do
		"$DIR/paper" --reload

		(
			pgid=$(ps -o pgid= -p "$(pgrep -fo "paper --monitor picture-uri")" | tr -d ' ')

			if [[ -n "$pgid" ]]; then
				kill -- -"$pgid"
			fi

			setsid "$DIR/paper --monitor" "$("$DIR/paper" --uri)" &
		) &
	done
}

monitorScheme

Can anyone convert this to a C program and create a pull request? I dont know how to code C tbh.
