Futil Web Demo

This uses calyx as a library to provide an interactive web demo for the Futil compiler. Futil is compiled to webassembly and wrapped in simple javascript that interfaces with the compiler.

Building

For now, this repository uses a git checkout of the Futil repository.

Setup Build Environment

You need Rust and Node.js and NPM installed. To get WebAssembly support, the easiest way is to install Rust with rustup as opposed to a package manager.

Then install wasm-pack with:

cargo install wasm-pack wasm-bindgen-cli

Now you are ready to build and run the web demo. First, install the npm dependencies with:

npm i

Compiling and Testing

Run a test web server with:

npm start

The server will automatically refresh if you change any of the JavaScript or Rust code. You can build standalone files with:

npm run build
