hyprpaper script to execute with waybar

hyprpaper_refresh.md

Random Wallpaper functionality with hyprpaper, waybar, and hyprland

This assumes you are using Hyprland and have Hyprpaper installed.

Don't forget to update your WALLPAPER_DIR path. Also, I put the script in my .config/hypr folder, you should put it where you keep your shell scripts.

hyprpaper_refresh.sh

#!/bin/bash
ATTEMPTS=0
MAX_NUM=10
FILES=()
WALLPAPER_DIR="/usr/share/backgrounds"
CURRENT_WALL=$(hyprctl --instance 0 hyprpaper listloaded)
WALLPAPER=""

while true; do
    ((ATTEMPTS++))
    echo "Attempt #$ATTEMPTS"

    if (( ATTEMPTS > MAX_NUM )); then
        notify-send "Error: we tried to set the following files: ${FILES[*]}"
        exit 1
    fi

    WALLPAPER=$(find "$WALLPAPER_DIR" -type f ! -name "$(basename "$CURRENT_WALL")" | shuf -n 1)
    if [[ -z "$WALLPAPER" ]]; then
        notify-send "Error: No suitable wallpapers found."
        exit 1
    fi

    MIME_TYPE=$(file --mime-type -b "$WALLPAPER")
    if [[ ! "$MIME_TYPE" =~ ^image/ ]]; then
        echo "$WALLPAPER - $MIME_TYPE"
        FILES+=("$WALLPAPER")
        notify-send "WARNING" "The selected file '$WALLPAPER' is not an image (MIME type: $MIME_TYPE)."
    else
        echo "Setting: $WALLPAPER"
        # Apply the selected wallpaper
        hyprctl --instance 0 hyprpaper reload ,"$WALLPAPER"
        break
    fi
done
