README.md
Boa
This is an experimental Javascript lexer, parser and compiler written in Rust. Currently, it has support for some of the language.
This project is an attempted rewrite of Bebbington's js.rs. Most of the Rust code has been rewritten from scratch.
Live Demo (WASM)
https://jasonwilliams.github.io/boa/
You can get more verbose errors when running from the command line
Contributing
If you don't already have Rust installed rustup is the recommended tool to use. It will install Rust and allow you to switch between nightly, stable and beta. You can also install additional components.
curl https://sh.rustup.rs -sSf | sh
Then simply clone this project and cargo build
To develop on the web assembly side you can run yarn serve then go to http://localhost:8080
Debugging
See Debugging
VSCode and Dockerfile
If you don't want to install everything on your machine, you can use the Dockerfile. Start VSCode in container mode (you may need the docker container plugin) and use the Dockerfile.
Web Assembly
This interpreter can be exposed to javascript! You can build the example locally with:
$ yarn install
$ yarn serve
In the console you can use window.evaluate to pass JavaScript in
