# JuleProtonUp (jpu)
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.<br>
The tool's main goal is to provide a **faster** [ProtonUp] implementation. The original project is written in Python, which is quite slow.

## Installation

### Arch Linux
[jpu](https://aur.archlinux.org/packages/jpu) is available on the AUR. You can install it using an AUR helper, e.g. paru:
```sh
paru -S jpu
```

### Nix
There is a [flake] available for jpu. You can run it directly with:
```sh
nix run 'github:adamperkowski/jpu?submodules=1'
```
or install it by adding the following to your system's `flake.nix`:
```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
        ];
      }];
    };
  };
}
```

### Manual
You can either download the pre-built binaries from [GitHub releases](https://github.com/adamperkowski/jpu/releases) or [build from source](#building-from-source).<br>
With the binary downloaded, you can move it to a directory in your `PATH` variable, e.g. `/usr/bin`:
```sh
sudo mv jpu /usr/bin
```

## Usage
To install the latest [Proton-GE] version, simply run:
```sh
jpu
```

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

## Building from source
To build jpu from source, you need to have the JuleC compiler (and [make]) installed. Please refer to [Jule's Manual][julec_installation].<br>
With the repository cloned and the submodules initialized with:
```sh
git submodule update --init
```
you can build the tool by running either:
```sh
make
```
or
```sh
mkdir -p build
julec . -o build/jpu
```
The `jpu` binary will be located in the `build` directory.
