What is Lithium?

Lithium is an attempt at several things at once:

• An assembler for x86 CPUs, written in Clojure and using Clojure S-expressions as its input data. This part has been first announced in this blog post.
• A compiler for a toy Lisp-like language, using that assembler as a backend. The compiler is being written following the guidelines found in a paper "An Incremental Approach to Compiler Construction."

The purposes of Lithium are, first and foremost, to learn and to have fun.

Try it out

In the REPL:

(require '[lithium.compiler :as compiler])
