Ruffle is an Adobe Flash Player emulator written in the Rust programming language. Ruffle targets both the desktop and the web using WebAssembly.
Ruffle supports ActionScript 1, 2 and 3 pretty well, but it's still not finished by any means. Please report any issues in the Issue Tracker.
The easiest way to try out Ruffle is to visit the web demo page, then click the "Select File" button to load a SWF file of your choice.
Nightly builds of Ruffle are available for desktop and web platforms.
For more detailed instructions, see our wiki page.
- Latest stable channel of Rust
- Java, available on your PATH as
java(required for building the library containing the builtin Flash classes for ActionScript 3)
The following are typical dependencies for Linux:
- libasound2-dev
- libxcb-shape0-dev
- libxcb-xfixes0-dev
- libgtk-3-dev
- libudev-dev
- libxcb-xinput-dev
- libxcb-xkb-dev
- libxcb-cursor-dev
- default-jre-headless
- cmake
- g++
Use the following command to build and run the desktop app:
cargo run --release --package=ruffle_desktop
To run a specific SWF file, pass the SWF path as an argument:
cargo run --release --package=ruffle_desktop -- test.swf
To build in debug mode, simply omit --release from the command.
Ruffle desktop can be built from our Homebrew Tap:
brew install --HEAD ruffle-rs/ruffle/ruffle
Note: because it is HEAD-only, you'll need to run brew upgrade --fetch-HEAD ruffle each time you want to update.
Follow the instructions in the web directory for building either the web or browser extension version of Ruffle.
This project is tested with BrowserStack.
Follow the instructions in the ruffle-android project for building the Android application of Ruffle.
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 --release --package=ruffle_scanner -- scan folder/with/swfs/ results.csv
If you have a SWF file and would like to capture an image of it, you may use the exporter tool. This currently requires hardware acceleration, but can be run headless (with no window).
cargo run --release --package=exporter -- path/to/file.swfcargo run --release --package=exporter -- path/to/file.swf path/to/screenshots --frames 5
