A small playground for checking out Cassowary constraints.
Please see the demo site for instructions: https://junon.me/cassowary-playground
Please do not judge me for the code written here. It was done in ~3 hours or so. It was purposefully hacked together to get it work as quickly as possible, and there is a lot of cursed nonsense across all of the languages used (Rust, Javascript and PEG.js).
The error handling on this is also abysmal. I didn't optimize for a great DX, as I wanted to play with some ideas as fast as possible (this is a tool I'm using to research automated circuit design tooling I'm interested in creating).
So, if you're a recruiter or otherwise looking at my profile for reasons to judge, feel free, but please know this code was a wreck from the first minute I started on it and I do not have any interest in improving it. Sorry about that!
The interface between the WASM binary and Javascript is embarassingly crude as I didn't want to get WASI involved (I don't particularly approve of WASI's design decisions so tend to avoid it) and didn't want the hastle of another build tool (wasm-pack) so I just went without any string or complex type support in the FFI end of things. Worked out okay, just needed to use a stack-based stateful protocol. I should probably mention that you should avoid stateful stack-based protocols when you can.
Also, please ignore the globals in Rust. I'm... aware. I know.
tl;dr please don't take any code here as "good" or "I should copy this" material. It's all really bad.
You'll need npm, node and cargo with a suitably recent toolchain and the wasm32-unknown-unknown
target installed.
Then run make and serve the /www/ directory that is generated.

I will not be enforcing it, though. Go nuts.
