Wrote a tiny WebAssembly (wat2wasm) compiler in Go
As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future! It misses a lot of features (that will be gradually implemented). Any feedback is welcomed!! Demo: https://luna-demo.vercel.app
In plain words
This is a minimal WebAssembly compiler written in Go that converts WebAssembly text format (WAT) to binary format (WASM). Built as an educational project, it's designed to help developers understand WebAssembly internals and Go programming through heavily documented code. The compiler currently lacks many advanced features but aims to gradually expand functionality. It's intended for anyone interested in learning how WebAssembly compilation works rather than production use.

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
