rjs

Native Javascript environment using Rust and Mozilla's SpiderMonkey JS engine.

Why?

This project would like to be:

• A way to use Javascript to make Android games, using a thin WebGL/GLES binding.
• Javascript compatible with Node.js.
• An easy to use binding for Rust projects to embed a Javascript engine.
• A superhero.

This is going to take a lot of work, and there are things for everyone to do, so peek into the Issues and look for a "help wanted" issue to get started!

Why not?

• Why not use straight Rust?
  Javascript with hot module reloading has a faster edit-compile-run cycle.

• Why not V8?
  It's time for SpiderMonkey to find more uses outside of Firefox.

Build

• Ensure you are using rust nightly: https://doc.rust-lang.org/1.13.0/book/nightly-rust.html
• If you attempt cargo build and receive: error[E0412]: cannot find type NonNull in module ptr then you are not using nightly.
• confirm with rustc --version
• On debian rust nightly installs to /usr/local/bin/rustc & the standard rustup installs to ~/.cargo/bin/rustc
• git clone --recursive https://github.com/rjs-team/rjs.git
• cd rjs
• cargo build
• Test with:
  • ./target/debug/rjs ./examples/webgl/webgl.js
  • If all went well you should see:
