Huge fan of Tinygo. I use it for the reduced WASM sizes. I see ~10x reduction when using it. I am working on a project that does some business logic/text parsing[0] that I want to be available on multiple platforms. With TinyGo + wasmer[1] I can build a library that is usable in Python, PHP, Javascript and C++. It has been a lot of fun for me. Lots of rough edges still exist when moving between WASM/calling language, but when you get it working it feels amazing.

Tinygo is neat, but the one time I tried to use it in practice, it failed me. The following program will panic when compiled to wasm: package main import "encoding/json" func main() { var parsed interface{} json.Unmarshal([]byte(`{"test":42}`), &parsed) } (It's been a while, so I forgot the problem with it was.) I'm curious what kind of text parsing you do. I ended up rolling with valyala/fastjson, but that's very much not what I was imagining. Lots of existing libraries don't work either, and finding out what does and what doesn't is pain. Is there some trick to working with it?

  I don't think "encoding/json" is fully working yet. Seems to be importable now, although tests are not passing. See supported packages here: https://tinygo.org/docs/reference/lang-support/stdlib/ https://tinygo.org/docs/reference/lang-support/stdlib/ Definitely still a ways to go before the full stdlib is usable. Looks like your code still fails at runtime with the error: panic: unimplemented: (reflect.Type).NumMethod() Tested here: https://play.tinygo.org/ https://play.tinygo.org/

Dunno bro, it doesn't work on the 6502, so... ;)

  By today standards, 6502 is a nanocontroller... or maybe even a picocontroller. Go buy yourself a real microcontroller, y'hear me? /s

    I mean in a world where a 32-bit microcontroller with flash in the 1-2MB range and a few hundred KiB RAM can cost less than $2 why make things harder on yourself :P If you're using a chip without the bells and whistles for precise timing reasons, then you're probably gonna program it in assembly too anyways
