PolyMC is a custom launcher for Minecraft that focuses on predictability, long term stability and simplicity.

This is a **fork** of the MultiMC Launcher and not endorsed by MultiMC. The PolyMC community felt that the maintainer was not acting in the spirit of Free Software so this fork was made.

### <img src="https://lotar.altervista.org/wiki/_media/news/slackware-logo.png" height="20" /> Slackware

[A SlackBuild](https://codeberg.org/glowiak/SlackBuilds/src/branch/master/repository/polymc.md) is available. You will need [qt5](http://slackbuilds.org/repository/14.2/libraries/qt5/) (on 15.0 installed by default), [a JDK](https://codeberg.org/glowiak/SlackBuilds/src/branch/master/repository/adoptium-jdk8.md), and if you're on 14.2, you need to compile newer CMake version manually. To build, type in extracted directory with all dependiences met:

    sudo ./polymc.SlackBuild
    sudo installpkg /tmp/polymc-version-arch-1_SBo.tgz

You can also download a community-maintained [prebuilt x86_64 package](http://glowiak.github.io/file/polymc-latest-slackware) and install it with /sbin/installpkg:

    sudo /sbin/installpkg ~/Downloads/polymc-version-x86_64-1_SBo.tgz

- [Gzipped binaries](http://glowiak.github.io/file/polymc-latest-fbsd64-raw) - traditional way to distribute, unpack and run.

In both cases you need X11, Qt5 and Java installed. Both files are 64bit only.  
You can build from source - see [BUILD.md](./BUILD.md)

## Development Builds

There are per-commit development builds available [here](https://github.com/PolyMC/PolyMC/actions). These have debug information in the binaries, so their file sizes are relatively larger.
Portable builds are provided for AppImage on Linux, Windows, and macOS.

For Debian and Arch, you can use these packages for the latest development versions:  
[![polymc-git](https://img.shields.io/badge/aur-polymc--git-blue)](https://aur.archlinux.org/packages/polymc-git/)

# Help & Support

Feel free to create an issue if you need help. However, you might find it easier to ask in the Discord server.

[![PolyMC Discord](https://img.shields.io/discord/923671181020766230?label=PolyMC%20Discord)](https://discord.gg/xq7fxrgtMP)

For people who don't want to use Discord, we have a Matrix Space which is bridged to the Discord server:

[![PolyMC Space](https://img.shields.io/matrix/polymc:polymc.org?label=PolyMC%20Space&server_fqdn=matrix.polymc.org)](https://matrix.to/#/#polymc:polymc.org)

If there are any issues with the space or you are using a client that does not support the feature here are the individual rooms:

# Development

If you want to contribute to PolyMC you might find it useful to join our Discord Server or Matrix Space.

## Building

If you want to build PolyMC yourself, check [BUILD.md](BUILD.md) for build instructions.

## Code formatting

Just follow the existing formatting.

In general, in order of importance:

- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
- Prefer readability over dogma.
- Keep to the existing formatting.
- Indent with 4 space unless it's in a submodule.
- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.

## Translations

The translation effort for PolyMC is hosted on [Weblate](https://hosted.weblate.org/projects/polymc/polymc/) and information about translating PolyMC is available at https://github.com/PolyMC/Translations
