A lightweight and fast tool for installing, updating and managing Proton, Proton-GE and Wine versions.

jpu is written in Jule, a low-level, compiled, memory-safe fast programming language.
The tool's main goal is to provide a faster ProtonUp implementation. The original project is written in Python, which is quite slow.

jpu is available on the AUR. You can install it using an AUR helper, e.g. paru:

paru -S jpu

There is a flake available for jpu. You can run it directly with:

nix run 'github:adamperkowski/jpu?submodules=1'

or install it by adding the following to your system's flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    jpu = {
      url = "github:adamperkowski/jpu";
      submodules = true;
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
  outputs = { self, nixpkgs, jpu }: {
    nixosConfigurations.example = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [{
        environment.systemPackages = [
          inputs.jpu.packages.x86_64-linux.default
        ];
      }];
    };
  };
}

You can either download the pre-built binaries from GitHub releases or build from source.
With the binary downloaded, you can move it to a directory in your PATH variable, e.g. /usr/bin:

sudo mv jpu /usr/bin

To install the latest Proton-GE version, simply run:

jpu

Available arguments:

• --dir (-d): Set the target installation directory (default: ~/.steam/root/compatibilitytools.d/)
• --help (-h): Display CLI information

To build jpu from source, you need to have the JuleC compiler (and make) installed. Please refer to Jule's Manual.
With the repository cloned and the submodules initialized with:

git submodule update --init

you can build the tool by running either:

make

or

mkdir -p build
julec . -o build/jpu

The jpu binary will be located in the build directory.
