[Langcraft] is the Minecraft LLVM target you've never wanted.

Langcraft started as a dare to the `#lang-dev` channel of the Rust

Community Discord to be able to parse Rust code in Minecraft.

Naturally, it grew into a full code generator that can translate

most LLVM IR to

[Minecraft data packs](https://minecraft.gamepedia.com/Data_Pack),

the game's deliberately-limited in-game scripting language. Langcraft

is entirely language independent, so any language with an LLVM-based

compiler can (with the right API bindings) run in Minecraft. Currently

bindings to both C and Rust exist. While not as visually impressive as

a redstone computer, Langcraft does stretch the bounds of the game quite

a bit, using jukeboxes for memory, armor stands to represent pointers,

and rearranging compiled code to make it run in the bounds of the data

packs' fixed instruction limit.

This is all, naturally, entirely useless. The project is also still

heavily work-in-progress and does not pretend to be stable, but it is

usable. A handwritten interpreter for a Rust-like language has already

been demonstrated running, and even more complex projects like [CHIP-8

emulators](https://github.com/Dhole/chip8-rs.git) function (albeit at

extremely slow speed).
