Jones Forth is the best program I've read in a long time. It's a complete Forth system written as a literate program by Rich Jones. There are two source files: jonesforth.s, the kernel written in GNU i386 assembler, and jonesforth.f, the higher-level parts of Forth written in itself. Recommended reading! See also the coverage on LtU.
I've truly wasted my life up to now by not programming in the one true
