KubeJS: RTJC (Runtime Java Compiler)

CurseForge

Introduction

This mod is a proof of concept, OK? Please don't use it in anything serious. It might break at random, or do wacky uncharacteristic things at any given point. Got it? Okay, on with the show.

KubeJS: RTJC is a plugin for KubeJS that allows you to compile and run Java code at runtime. The speed is probably abysmal, it's not very simple to use, but god damn it I had fun making it, so you have to endure it.

On the bright side, I've included a simple example of how to use it right under this line I'm typing right now that'll end any moment now in 5... 4... 3... no wait please be quiet in the back there, I can hear you shuffling and it's very distracting, let's start again. 5... 4... 3... 2... 1... example time!

Usage

addImport("dev.latvian.kubejs.util")
jankBuilder = createClass()
jankBuilder.addMethod("public static void tell(MessageSender target, String message) {" +
    "target.tell(new net.minecraft.util.text.StringTextComponent(message));" +
    "}");
jankBuilder.addMethod("public static String getName(MessageSender target) {" +
    "return target.getName().toString();" +
    "}");
jank = finalizeClass(jankBuilder)
removeImport("dev.latvian.kubejs.util")


onEvent("player.chat", (event) => {
    if (event.message.startsWith("!test")) {
        jank.tell(event.player, "Hi, " + jank.getName(event.player) + "!");
    }
})

You can use imports by using the addImport function, you can import .* by not including the .* part, or import per-class by using the fully qualified name. To resolve conflicts you can either use the fully qualified name of a class, or if import pollution is your issue, removeImport will undo an import.

To see the generated class files, enable debug mode by using rtjcSettings.debug = true, class files will be written to logs/kubejs/rtjc

Compiling

Hopefully, if I've done everything right, you should just be able to clone this repository, import it into your IDE of choice, and run the build task in gradle. If not, please let me know, joking aside I'm a big believer in "download and build" and if any of my intended-for-the-public projects don't work like that, I'd like to fix it.

Outroduction

Once again I must re-iterate, please do not use this mod in anything that requires stability. Thanks.
