nix-minecraft

A Minecraft launcher in nix.

Support for:

• forge
• fabric
• liteloader
• modpacks from
  • curseforge
  • feed the beast

Fully declarative and reproducible.

Usable either standalone, or as a home-manager module.

Requirements

Nix with flake support.

Standalone usage

Run:

$ nix flake init -t github:12Boti/nix-minecraft

This will create a flake.nix file in the current directory. You can customize it, all options are documented at https://12boti.github.io/nix-minecraft

To start minecraft, just

$ nix run

Usage with home-manager

Add

inputs.nix-minecraft.url = "github:12Boti/nix-minecraft";

to your flake inputs. The home-manager module will be at nix-minecraft.nixosModules.home-manager.minecraft

Write your configuration at programs.minecraft.versions.<name>, where <name> is some string identifying that installation. You can have as many installations as you want.

If you want some options to apply for all installations, put them in programs.minecraft.shared

All installations will have a directory at ${programs.minecraft.basePath}/<name>/ (by default .minecraft/<name>/), which contains the game directory gamedir (where your worlds and settings are saved) and an executable named run which starts Minecraft.

Example

{
  programs.minecraft = {
    shared = {
      username = "NixDude";
    };
    versions = {
      "vanilla18" = {
        minecraft.version = "1.18";
      };
      "projectozone3" = {
        modpack.curseforge = {
          projectId = 256289;
          fileId = 3590506;
          hash = "sha256-sm1JihpKd8OeW5t8E4+/wCgAnD8/HpDCLS+CvdcNmqY=";
        };
        forge.hash = "sha256-5lQKotcSIgRyb5+MZIEE1U/27rSvwy8Wmb4yCagvsbs=";
      };
    };
  };
