chip8-book VS wefx

Not to discourage you, but there's already a CHIP-8 book in progress: https://github.com/aquova/chip8-book

WASM support would be so cool. There are lots of guides online which could help you out. I saw a guide for the chip8 and it didn't even look too difficult, you can check it out here https://github.com/aquova/chip8-book

Recently I've decided to learn low level programming with Rust. I asked for some projects to practice and got recommened to make a Chip8 emulator. That sounded fun so I searched a bit and found this guide that walks you step by step.

I made some emulators in Rust as a learning project during the start of the pandemic, and ran into the exact same issue when I wanted to make a wasm version to run in a browser. Eventually, I was able to figure out how to do it, although I do use the 'wasm-pack' Cargo package to assist with it (I think you can get away without it if you're really motivated, you just need to set up the targets and other elements yourself). Basically you define some Rust API to expose whatever you need from your project, then that and the project get compiled into one .wasm binary and some (surprisingly readable) JavaScript "glue" gets generated which allows for easy inclusion into a web page. It works well for code in the std, but I've had issues with 3rd party packages.

It's focused on emulation development, but I wrote a document that describes the process I followed: https://github.com/aquova/chip8-book/blob/master/src/wasm.md

I followed [this](https://github.com/aquova/chip8-book) book which uses Rust.

I'm particularly curious on what parts cheerp adds to their clang+llvm base. Presumably it's something like the C standard target library for WASM/JS?

For reference, here's examples of what you could do with the baseline clang with wasm (but not JS?) [1] [2] [3], referenced from a similar thread on HN.

I've used a similar pipeline to create "books for code and infrastructure". A/k/a coding in a somewhat literate programming style. Similar to what is described here:

gemini://gemini.robrohan.com/2022-04-23-narrative-programming.md

With output that looks similar to this: https://github.com/robrohan/wefx/blob/main/docs/manual.pdf

Using a github action like this: https://github.com/robrohan/wefx/blob/main/.github/workflows...

(most of the code borrowed from those projects)

You can do it with just plain markdown files and use directories for chapters / organization if you're just going for prose.

I've thought about using the process to try to make open textbooks where you can mix and match chapters, but I don't have any experience in that field.

Anyway, can confirm, it's an incredibly useful process.

Not trying to steal your thunder, but here is another nostdlib clang -> wasm example with malloc, a few math functions, rand, and writing to a canvas doing animation.

I haven’t seen this version mentioned in the thread - if you don’t need a lot of precision, here is a simple 4 line version[1] and here’s how it works[2].

Not sure who initially came up with it.
