Krysztal's fork of fabric-language-scala

This is a fork of fabric-language-scala,support the newest LTS Scala3 version and bundled Scala Library.

Why fork?

The number of people who use Scala is very small, but the power of Scala's expressiveness makes the language practically perfect for developing mods.

The original fabric-language-scala was unmaintained and the maintainers couldn't spare any more effort to maintain it, so it slowly became unmaintained and non-functional.

Support for Scala3 is, if anything, almost non-existent.

So I decided to fork it and maintain it myself and implement it to be compatible with the original fabric-language-scala,named krysztal-language-scala.

NOTE

This language adaptor will synchronize content upstream as much as possible and will ensure availability as much as possible.
This language adaptor only provide LTS version of Scala3

Bundled libraries

From a number of perspectives, the library needs to bind some popular scala libraries.

org.scala-lang:scala3-library_3:3.3.3
org.scala-lang:scala-library:2.13.12
org.typelevel:cats-core_3:2.12.0
com.chuusai:shapeless_2.13:2.3.12
org.typelevel:mouse_3:1.3.1

How to use?

Add dependence

Add those lines to your project's build.gradle


plugins {
  ...
	id 'scala' // Add `scala` plugin for gradle
  ...
}

repositories {
  ...
	maven { url "" rel="noopener nofollow" target="_blank">https://maven.dragons.plus/releases&quot; }
  ...
}

dependencies {
  ...
	modImplementation "dev.krysztal:krysztal-language-scala:$VERSION$"
  ...
}

Usage: `class`

Suppose your entry name is ExampleEntry.scala

import net.fabricmc.api.ModInitializer;

class ExampleEntry extends ModInitializer {
   lazy val logger = LoggerFactory.getLogger("KMMO")
   override def onInitialize(): Unit = {
       logger.info("Hi")
   }
}

And in fabric.mod.json

    ...
 "entrypoints": {
    "main": [
      "dev.example.ExampleEntry"
    ],
  },
    ...

But thanks to Scala's excellent interoperability with Java, we can use this library simply as a Java entry point :)

Usage: `object`

Suppose your entry name is ExampleEntry.scala

import net.fabricmc.api.ModInitializer;

object ExampleEntry extends ModInitializer {
    lazy val logger = LoggerFactory.getLogger("KMMO")
    override def onInitialize(): Unit = {
        logger.info("Hi")
    }
}

And in fabric.mod.json

    ...
 "entrypoints": {
    "main": [
      {
        "adapter": "scala",
        "value": "dev.example.ExampleEntry"
      }
    ],
  },
    ...

Known issues

unknown invokedynamic bsm: scala/runtime*

This issues caused by scala's class loading mechanism.

It won't affect almost anything. Ignore it.
