Snek: A Python-Inspired Language for Tiny Embedded Computers

on YouTube ↗44m

" summary

A Python subset called Snek compiles to a small bytecode VM that runs in 32kB ROM and 2kB of RAM, targets ATmega328 boards and the classroom workflow, and passes a test suite to ensure Snek answers match CPython except for board I/O. Implementation highlights include NaN tagging to pack pointers and 32-bit floats into 32-bit values, an in-place compacting incremental GC that avoids double heaps, and a tiny parser generator lola that is about 1/10 the size of bison. LEGO robot demos and a Mu/SnekDE IDE show the system working for middle-school lessons.
