Ruffle

Ruffle is an Adobe Flash Player emulator written in the Rust programming language. Ruffle targets both the desktop and the web using WebAssembly.

Project status

Ruffle is in the proof-of-concept stage and can currently run early Flash animations. ActionScript support is still forthcoming; for more info, read the project roadmap.

Building from source

Follow the official guide to install Rust for your platform.

Desktop

• cargo run --package=ruffle_desktop -- test.swf

Web

• Install Node.js
• Install wasm-pack

Running the web demo

• cd web/demo
• npm install
• npm run serve
• Load indicated page in browser (usually http://localhost:8080)

Building the NPM package

• cd web
• wasm-pack build

Scanner

If you have a collection of "real world" SWFs to test against, the scanner may be used to benchmark ruffle's parsing capabilities. Provided with a folder and an output filename, it will attempt to read all of the flash files and report on the success of such a task.

• cargo run --package=ruffle_scanner -- folder/with/swfs/ results.csv

Structure

• core contains the core emulator and common code
• desktop contains the desktop client (uses glium)
• web contains the web client (uses wasm-bindgen)
• scanner contains a utility to bulk parse swf files
