PolyMC 5

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. Read "Why was this fork made?" on the wiki for more details.

Packages

Several source build packages are available, along with experimental pre-built generic packages.

• An AUR package is available.
• A Gentoo ebuild is available in the swirl overlay, named games-action/polymc. Check the README for instructions on how to add the overlay.
• A Flatpak is available in Flathub. You can install it from there or build it yourself using this source.
• Generic, prebuilt packages (archived by version) can be found here (latest).
• Last build status: https://jenkins.polymc.org/job/PolyMC/lastBuild/
• Linux (AMD64) System (SHA256) - this is a generic system package intended to be used as a base for making distro-specific packages.
• Windows (32-bit) (SHA256) - this is a portable package, you can extract it anywhere and run it. This package needs testing.
• Debian (AMD64) (SHA256) - this is intended to be installed with dpkg -i. Alternatively, you may build the .deb yourself, by going to packages/debian and running ./makedeb.sh.
• AppImage (AMD64) (SHA256) - chmod +x must be run on this file before usage. This should work on any distribution.
• MacOS currently does not have any packages. We are still working on setting up MacOS packaging.

Development

If you want to contribute to PolyMC you might find it useful to join #development:polymc.org on Matrix or join our Discord server, which is bridged with the PolyMC Matrix rooms. Thank you!

Building

If you want to build PolyMC yourself, check 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.

Forking/Redistributing/Custom builds policy

Do whatever you want, we don't care. Just follow the license. If you have any questions about this feel free to ask in an issue.

Help & Support

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

For people who don't want to use Discord, we have a Matrix Space which is bridged to the Discord server. Be sure to enable spaces first (Settings -> Labs -> Spaces), and then you may join the space:

Matrix's support for spaces is still in development, so if you have issues accessing rooms via the space, then you can join the rooms directly:
