Prism Launcher

Prism Launcher is a free and open source launcher for the game Minecraft. It is written in C++ and uses the Qt Toolkit.

Installation

Using nix-shell

$ nix-shell -p prismlauncher

Using global configuration

environment.systemPackages = with pkgs; [ prismlauncher ];

Using home configuration

home.packages = with pkgs; [ prismlauncher ];

Configuration

Basic

Configuration of the launcher itself can be done in the settings window of the launcher. Currently, there is no way to configure Prism Launcher declaratively.

Advanced

You can override prismlauncher to change the environment available to the launcher and the game. This might be useful for installing additional versions of Java or providing extra binaries needed by some mods.

environment.systemPackages = with pkgs; [
  (prismlauncher.override {
    # Add binary required by some mod
    additionalPrograms = [ ffmpeg ];

    # Change Java runtimes available to Prism Launcher
    jdks = [
      graalvm-ce
      zulu8
      zulu17
      zulu
    ];
  })
];
