This is stianloader's mixin. This fork targets general-purpose environments, mostly detached from mainstream modloaders such as modlauncher, legacylauncher, or fabric.
Mixin is a trait/mixin framework for Java using ASM and hooking into the runtime classloading process via a set of pluggable user-provided services.
The main documentation for Mixin can be found in the Wiki.
Additional documentation for individual features and annotations can be found in the extensive Javadoc. For additional help:
Binaries are available through stianloader's maven repository. Artifacts are published in that repository via our jenkins pipeline by nighly-paperpusher, meaning that a binary is created for (almost) every commit to the repository.
Due to our rather quick release cadence, and the fact that this is a fork of a fork, the versions assigned to artifacts might be a little bit odd.
Versions for testing will follow the following versioning scheme:
A.B.C-X.Y.Z-V
Where as A, B, C are the major, minor and patch numbers for the version of fabric's mixins
this project is following. Similarly, X, Y, and Z compose the version number of the mixin
version of sponge's upstream repository. V is this project's breaking change counter. It is
incremented for every breaking change performed by the stianloader organisation.
Versions in the repository meanwhile will follow the following scheme:
A.B.C-X.Y.Z-V-aJJJJMMDD.I
While the .I part is omitted for the first build of each day, it is a 0-indexed number
represeting that is appended whenever collisions would otherwise occur. The number makes
itself quite frequently known whenever hotfixes have to be deployed (e.g. due to a typo).
The JJJJMMDD is the year, month and day the build was published.
For a list of all published versions, see https://stianloader.org/maven/org/stianloader/sponge-mixin/ Note: It's best if you sort by date of last modification. The default string comparision isn't the best for our versioning scheme.
Enhanced functionality for working with Mixin in IntelliJ IDEA is available via the Minecraft Development for IntelliJ IDEA plugin developed by DemonWav.
- Removed launchwrapper, modlauncher, AP, fernflower, and other modules that are not frequently used outside minecraft or could easily be replaced.
- The module-info.class file is now compiled with Java 9, instead of Java 16.
- Integrated the agent module in the core module.
- Compiling against ASM 9.8 by default, instead of the previous 9.0
