MixinBooter

Allows any mixins that work on mods to work effortlessly on 1.8 - 1.12.2

• Current Mixin Version: CleanMix 0.2.9 by CleanroomMC, a fork of SpongePowered/Fabric Mixin (0.8.7)

• Current MixinExtra Version: 0.5.4

Pseudo-Changelog:

• As of 4.2, MixinBooter's API has changed and all mods that uses mixins are encouraged to depend on MixinBooter, even those that mixin into vanilla/forge/library classes. To avoid mixin version mismatches with mods crashing trying to implement modded mixins (looking at you VanillaFix). Thanks to @embeddedt recommending and helping me introduce this change!

• As of 5.0, MixinExtras by @LlamaLad7 is shaded. Available for developers to use.

• As of 8.0, MixinBooter will now work from 1.8 - 1.12.2. One single build works with all these versions! (TODO: LiteLoader support?)

• As of 8.4, MixinBooter actively attempts to be compatible with SpongeForge

• As of 9.2, MixinBooter reinstates the older MixinLoader annotation for 1.8.x usages.

• As of 10.0, MixinBooter follows Mixin 0.8.7

• As of 11.0, MixinBooter is built on CleanMix. As an effort to create an unified backend with Cleanroom.

  • No longer would you need to declare dependencies for the annotation processor yourself.
  • Also adds a config file (config/mixinbooter.cfg) to blacklist mixin configs and toggle debug options
  • Dedicated logs/mixinbooter.log mixin log. With ability to trace class-loading for precise debugging.
  • Allows traditional MixinConfig + MixinConnector manifest attribute entries to be fully involved in the ecosystem
  • Mod discovery for mixin owners, better isModLoaded checks
  • Suppresses Forge's corrupt zip warnings
  • Phased out mixin "phases"

For Developers ~ Getting Started:

1. Add CleanroomMC's repository and depend on MixinBooter's maven entry:

repositories {
    maven {
        url 'https://maven.cleanroommc.com'
    }
}

dependencies {
    def mixin = 'zone.rong:mixinbooter:11.0'
    
    implementation (mixin) {
        transitive = false
    }
    annotationProcessor mixin

    // RetroFuturaGradle for refmap generation:
    modUtils.enableMixins(mixin)
    // modUtils.enableMixins(mixin, 'mod_id.mixins.refmap.json') << add refmap name as 2nd arg (optional)
}

2. Pick how to register your mixin configurations. MixinBooter supports lots of approaches:

(As of 11.0, early/late divide is no longer present, therefore IEarly/ILateMixinLoaders are deprecated)

• MixinConfigs manifest attribute: no loader class needed. Add a space-separated list of your mixin configuration names to your jar's manifest. MixinBooter reads it straight from the jar's manifest and registers them.
• MixinConnector manifest attribute: register configs programmatically. Point it at a class implementing org.spongepowered.asm.mixin.connect.IMixinConnector, its connect() is called during boot, where you call Mixins.addConfiguration(...) yourself.

Both manifest attributes are set on your jar task:

jar {
    manifest {
        attributes(
                'MixinConfigs': 'mixins.mymod.json',
                'MixinConnector': 'com.example.mymod.MyMixinConnector'
        )
    }
}

public class MyMixinConnector implements IMixinConnector {
    
    @Override
    public void connect() {
        // Check if mod is loaded before registering?
        // Possible with zone.rong.mixinbooter.service.ModDiscoverer.isModPresent(String modId)
        Mixins.addConfiguration("mixins.mymod.json");
    }
    
}
