CBL

The "C" either stands for "Chess", or "Cheeky". Either way pretty sure the "L" stands for "Lang"

Overview

• scanner.rs; converting raw files into the tokens
• ast.rs; struct for representation for a token which is more "interpretable"
• parser.rs; converting tokens into syntax tree files
• interpreter.rs; executing the syntax tree's directly

WASM

You can actually compile the interpreter and run it in the browser

wasm-pack build --target web

This should generate a directory which looks like

tree pkg 
pkg
├── README.md
├── cbl_lib.d.ts
├── cbl_lib.js
├── cbl_lib_bg.wasm
├── cbl_lib_bg.wasm.d.ts
└── package.json

You should be able to copy paste index.html in there, then play around with the repl with

cd pkg
python3 -m http.server

I reference the lox-rs impl a lot
