Personal Projects

BLSL

Github

BLSL is a high-level shading language I'm working on. The intent is to fill the middle ground between languages like Cg and FX that force the user to fit into a rigid framework, and platform-level languages which offer little/nothing in the way of solving application-level problems.

laminaFS

Github

LaminaFS is an asynchronous, virtual overlay filesystem. It supports user-defined "devices" for mounting archives, network paths, or whatever, and comes with a "directory" device out of the box.

dib

Github

Dib is a build system designed to leverage the Haskell language's features (build scripts are written in Haskell) while being more flexible and easier to use than systems like GNU make. Contrary to most build systems, it is a forward build system, meaning that products are defined from their pieces and built in the natural direction versus as an implicit graph driven by production rules.

2A03

Github

2A03 is a minimalist synthesizer based around the features present in the NES CPU of the same name. Songs are compiled from a high-level assembly language into bytecode that is then interpreted by the synthesizer.

libwaffle

Github

Libwaffle is a light-weight, modular synthesizer library that utilizes JACK for output and includes OSC support.

LuaGame

Repo

LuaGame is a rapid development tool for games that is based around the Lua programming language, SDL, and OpenGL.
