Compukter Kraft

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

- 🖥 Multiplayer-friendly editor — a block running its own VM on a background thread. - 📟 Multiplayer-friendly editor — bind it to any computer and carry your shell around. - 🛠 Multiplayer-friendly editor — an in-game IDE with multi-file editing, syntax highlighting, autocomplete and live error reporting. - 🧠 Multiplayer-friendly editor — a small, statically typed, Kotlin-flavoured scripting language. Compiles to bytecode, runs on a sandboxed VM. No reflection, no arbitrary host interop, no surprises. - 💾 Multiplayer-friendly editor — 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.
