Yotta

Welcome to Yotta! Yotta is a minimalistic forth-like language. Its most distinctive feature is that it comes with very few primitives:

$XX emits the machine code XX given in hexadecimal.
^XX emits machine code that emits machine code XX.
: A defines a new word A

The rest is built-up from there. Yotta is split into several parts, in the src directory:

src/0-preamble.fs is the zeroth chapter. It defines some bare necessities, like ; and comments.
src/1-assembler.fs defines an x86-64 assembler inside of yotta.
src/2-forth.fs defines a set of forth-like words, built on top of the assembler.
src/3-main.fs is the program.
src/yotta.s contains the engine, written in NASM x86-64 assembly.

If this piques your interest, I recommend reading the preamble and the forth chapter, and the rest as interests you.

This code supports x86-64 linux and macos:

To build and run on linux, use make run-linux.
To build and run on intel macs, use make run-macos.
