The Kitten Programming Language
Kitten is a statically typed, stack-based functional programming language designed for simplicity, speed, and safety. This is an in-progress implementation of that language, including:
-
An interactive console for testing code.
-
An interpreter.
-
A compiler targeting C99.

Building 
To build the compiler, you need GHC 7.10. Simply run:
git clone https://github.com/evincarofautumn/kitten.git
cd kitten
make
You can run the integration tests concurrently with make -jn, where n is the number of concurrent jobs. If you are working on the compiler, you can use make dev to avoid checking the library dependencies on every rebuild.
