Tupai

Operating system

Tupai is a multitasking operating system written in Rust targeting i386, amd64 and armv7 architectures. It focusses on safety, stability, portability and correctness. It is not designed with a specific application in mind, but rather to act as a base for future experiments in software safety. Tupai does not conform to an existing operating system API (i.e: POSIX) but instead aims to implement a new and innovative design. Tupai has been rewritten upwards of 8 times in C, C++ and finally Rust.

Bread

Functional programming language

Bread is a statically-typed functional programming language with a compiler written in Rust. It features Hindley-Milner type inference, complex types, currying, a bytecode compiler backend, and beautiful error messages.

def len of (List Num) -> Num = l ->
	if l = []
	then 0
	else 1 + len(list:tail)

Forge

Dynamically-typed imperative programming language

Forge is a dynamically-typed programming language inspired by JavaScript, Rust, and Python. It aspires to be ‘JavaScript, but less shit’.

var basket = ["apple", "banana", "pineapple", "kiwi"];

var display = |item| {
	print("I have a" + item);
};

for item in basket {
	display(item);
}

You can try Forge online here.

Forge also has an (incomplete) successor, Leon

Euc

Software rendering library

Euc is a versatile, simple to use library that allows 3D rendering on the CPU. It has a portable, compact design that makes it perfect for prototyping ideas, unit testing, or even simple realtime applications.

Funki Crab

Optimising BrainFuck compiler

Funki Crab is an optimising Brainfuck compiler written in Rust. It’s capable of a large number of Brainfuck optimisation techniques and produces a significant speedup compared to naive compilation. The performance of programs emitted by Funki Crab are within the ballpark of the best optimising Brainfuck compilers available.

I created Funki Crab as an exercise in learning about compiler development, Immediate Representation (IR) techniques and optimisation. Brainfuck struck me as a sensible language for such a project given its simplicity, Turing-completeness and wealth of potential optimisations.

Funki Crab is an anagram of Brainfuck. ‘Crab’ is a reference to Ferris, the Rust mascot.

Veloren

Open-world, open-source voxel RPG and engine

Veloren is a multiplayer voxel RPG written in Rust that I founded. Veloren takes inspiration from games such as Cube World, Minecraft and Dwarf Fortress. Veloren’s world is procedurally-generated and makes use of advanced teleological generation techniques such as erosion simulation. The game is currently under heavy development, but is playable. Veloren has since grown into a large FOSS project with about 15 active developers.

Emul8

CHIP-8 emulator

Emul8 is an emulator for the CHIP-8 game system. It can run a variety of CHIP-8 ROMs including pong, space invaders, snake and tetris. Emul8 supports various debugging features such as instruction disassembly and step-through execution.
