Programmable computers for Minecraft — booted end-to-end on a custom Rust VM.

Inspired by ComputerCraft. With one big difference: the runtime is not Lua — it is a native Rust virtual machine (rux-vm) wrapped via JNI.

What you get

  • 💻 Notebook — a portable player-facing computer item that boots its own Rux VM instance on a background daemon thread.
  • 🖥 Rux VM — a deterministic, sandboxed virtual machine implemented in Rust. Boots Rux16 code from per-computer bios.flash files and storage0 ruxvol boot media.
  • 🔌 Display + input devices — accelerated framebuffer with copyRect / blitMono primitives, terminal input queue, and a per-device runtime workspace.

Status

Mid-rewrite. The legacy in-game CKL language stack, the Workbench IDE, the standalone Computer block, the Workbench/Terminal/Serial items, and the CKIM bytecode runtime have all been removed. The remaining player-facing surface is Notebook, booted through the Rust VM's Rux16 BIOS path (bios.flash → storage0.ruxvol boot entry → guest Rux16 execution).

Currently for NeoForge 1.21.1.
