PAX is the solution to modern modpack development for Minecraft, usable both alone and in a team. It supports Forge & Fabric, can be version controlled with git, and one command is all you need in order to upload your pack to Curseforge.

The following features are implemented:

  • ⌨️ CLI interface for quick actions
  • 🔎 Search & Install for Curseforge mods
  • 📥 Updating one mod or the whole modpack, automatically selecting the best available version
  • 👁️ Mod Information (compability & whether an update is available) at one glance (see above picture ;) )
  • 💾 Easily diffable files for ease of working with git
  • 🤖 Continous Integration where you push your project to Github/Gitlab and a runner automatically builds your modpack and uploads it to Curseforge. It's magic, woohoo!

The following features are on the roadmap for the following weeks:

  • 🔃 Minecraft Development Environment
    • Sync file changes between your project and your minecraft launcher, so you don't have to import your modpack every time you make a change.

Usage

The newest version of PAX is available here.

Information about how to use PAX is available on the wiki, which contains:

  • A Quickstart guide if you want to get up and running quickly
  • A Getting Started page for users that want to go more in-depth.

PAX Development

You'll need:

  • Nim
  • A C compiler (depending on your operating system, one might be already installed)

Clone and cd into the repository - and you're good to go!
Run nimble build to build the application for development, or run nimble build -d:release to create an optimized release build.
Execute the program with ./pax (on Linux) or pax.exe (on Windows).
