thud

thud, short for thumbnail directory, is a tool that lets you generate directory thumbnails from images inside them. Useful for a Dolphin/KDE-like experience with GTK-based file browsers that don't show the contents of directories by default.

thud can be customized with rules and strategies that reside in ~/.config/thud/config.toml. By default, it creates thumbnails from cover.{png,jpg} files.

Tested and works in: Caja, Nemo, Thunar, Nautilus.

Installation

NixOS (Recommended)

Add thud to your systemPackages and rebuild.

{ pkgs, ... }:

{
  environment.systemPackages = with pkgs; [
    thud
  ];
}

Arch Linux

I don't use Arch Linux anymore, but I wrote a PKGBUILD for the pacman enjoyers out there. Feel free to add it to the AUR.

git clone https://github.com/donovanglover/thud -b 0.3.1 && cd thud && makepkg -si

Other distributions

git clone https://github.com/donovanglover/thud && cd thud
cargo build --release

sudo install -Dm755 ./target/release/thud /usr/bin/thud
sudo install -Dm644 ./assets/thud.thumbnailer /usr/share/thumbnailers/thud.thumbnailer

Usage

Usage: thud [OPTIONS] <INPUT_DIRECTORY> <OUTPUT_FILE>

Arguments:
  <INPUT_DIRECTORY>  Directory to thumbnail
  <OUTPUT_FILE>      Where to save the output image

Options:
  -s, --size <INTEGER>  Thumbnail size [default: 128]
  -v, --verbose         Print what thud is doing
  -h, --help            Print help (see more with '--help')
  -V, --version         Print version

By default, directories with cover.jpg or cover.png will automatically generate cover images. You can customize this with ~/.config/thud/config.toml.

Contributing

Creating your own strategy for thud is easy for both new and experienced Rustaceans. Here are the steps:

1. First add a new function to ./src/strategy.rs
2. Next add your strategy to match rule.strategy.as_str() in ./src/main.rs
3. Finally, make a pull request to let anyone be able to use your thumbnailing strategy.

That's it! The possibilities are endless when it comes to how you want your directory thumbnails to look.
