Compukter Kraft

Programmable computers for Minecraft — but with a real, statically-typed language and a real IDE, right inside the game.

Inspired by ComputerCraft. With one big difference: the language is not Lua.

What you get

• 🖥 Advanced Computer — a block running its own VM on a background thread.
• 📟 Portable Terminal — bind it to any computer and carry your shell around.
• 🛠 Workbench — an in-game IDE with multi-file editing, syntax highlighting, autocomplete and live error reporting.
• 🧠 CKL — Compukter Kraft Language — a small, statically typed, Kotlin-flavoured scripting language. Compiles to bytecode, runs on a sandboxed VM. No reflection, no arbitrary host interop, no surprises.
• 💾 Per-computer file system — each computer has its own workspace on disk, edits survive reboots.
• 👥 Multiplayer-friendly editor — CRDT-based sync, two players can edit the same file at the same time without stepping on each other's text.

A taste of CKL

import terminal
import system

fun greet(name: String): String {
    return "Hello, " + name + "!"
}

fun main() {
    terminal.printLine(greet("world"))
    terminal.printLine("Computer #" + system.computerId())
}

Types are checked at compile time. Errors show up in the editor before you ever press Run. Because debugging Lua at 2 AM is a war crime.

Built-in modules

terminal, filesystem, system, events, process, strings — enough to write shells, file utilities, automation scripts, and small games.

Status

Early access. Working: language, VM, file system, advanced computer block, portable terminal, workbench IDE, multiplayer editor sync. Planned: more peripherals, networking between computers, compatibility for Create.

Currently for NeoForge 1.21.1.
