🖼️ Hyprland Wallpaper Switcher

A Rust-based wallpaper switcher for Hyprland, with automatic orientation detection, rotation tracking, and blurred lock screen background generation.

✨ Features

• Detects each monitor's orientation (landscape or portrait) using hyprctl
• Rotates wallpapers per-orientation, one per monitor
• Avoids repeating wallpapers until the list is exhausted
• Creates blurred + darkened overlays for use with swaylock-effects
• Automatically stores rotation state per orientation in ~/.cache/

📂 Expected Directory Structure

Your wallpapers should be stored in:

~/Pictures/Wallpapers/
├── nature1.jpg
├── anime_vertical.webp
└── urban_landscape.png

Orientation is auto-detected via image dimensions (not by subfolder).

🔧 Requirements

Make sure the following are installed and in your $PATH:

• hyprctl
• imagemagick (magick CLI for blur overlays)
• [identify](part of imagemagick) for resolution detection
• [walkdir](Rust dependency; bundled)

Optional for lock screen integration:

• swaylock-effects

🚀 Usage

1. Build the binary:

   cargo build --release
   

2. Run the app:

./target/release/wallpaper-switcher

It will:

• Load all wallpaper images under ~/Pictures/Wallpapers
• Assign images to monitors based on orientation
• Cycle through images and remember which one was used last
• Preload + apply wallpapers via hyprctl hyprpaper
• Create a blurred/darkened image per monitor in /tmp/hyprlock/<monitor>.png

3. (Optional) Add a keybind to your Hyprland config:

bind = $mod, W, exec, ~/dev/wallpaper-switcher/target/release/wallpaper-switcher

🔐 Lock Screen Integration

To use the blurred wallpapers with swaylock-effects, configure it like:

swaylock -i /tmp/hyprlock/DP-1.png

Each monitor will have a unique file based on its name.

💾 Caching & State

Rotation index is stored in:

~/.cache/hyprpaper_index_landscape
~/.cache/hyprpaper_index_portrait

These track your progress through each list and reset automatically when exhausted.
