Austin Z. Henley, a developer who writes code by hand on weekends, announced a code golf challenge to build a Python interpreter in just 1024 bytes of C code. The project explicitly avoids macros and external libraries.

Henley began by implementing a FizzBuzz program that mimics Python's syntax using colons and indentation without parentheses. He noted that fitting the entire Python language into such a small footprint is impossible, so he focused on a subset of syntax that looks "Pythony." His initial attempts were unsuccessful; a basic calculator quickly exceeded the 512-byte limit. He then shifted strategies, listing elements that look Python-like while acknowledging his code golf skills were insufficient for the 512-byte target.

He decided to make it work first, then make it small. The interpreter uses a minimal state held in global variables, a fixed-length array for raw code, and a symbol table for variables. It parses expressions recursively and handles control flow using the C call stack.

Loops work by jumping backwards and re-parsing source code each iteration. The project represents a unique exercise in language implementation constraints.
