## Project status
Ruffle is in the proof-of-concept stage and can currently run early Flash animations and games. Basic ActionScript 1.0/2.0 support is in place and improving; ActionScript 3.0 support is forthcoming. For more info, read the [project roadmap](https://github.com/ruffle-rs/ruffle/wiki/Roadmap).
## Using Ruffle
The easiest way to try out Ruffle is to visit the [web demo page](https://ruffle.rs/demo/), then click the "Browse..." button to load an SWF file of your choice.
[Nightly builds](https://ruffle.rs/#releases) of Ruffle are available for desktop and web platforms including the browser extension.
For more detailed instructions, see our [wiki page](https://github.com/ruffle-rs/ruffle/wiki/Using-Ruffle).
## Building from source
[Follow the official guide](https://www.rust-lang.org/tools/install) to install Rust for your platform.
You must also have Java installed, and available on your PATH as `java`.
### Desktop
If you are building for a Linux platform, the following are typical dependencies:
#### Ubuntu
* libasound2-dev
* libxcb-shape0-dev
* libxcb-xfixes0-dev
* libgtk-3-dev
* libssl-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.
## Homebrew
Ruffle Desktop can be built from our [Homebrew Tap](https://github.com/ruffle-rs/homebrew-ruffle/):
`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._
### Web or Extension
Follow [the instructions in the web directory](web/README.md#building-from-source) for building
either the web or browser extension version of Ruffle.
### 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 --release --package=ruffle_scanner -- folder/with/swfs/ results.csv`
### Exporter
If you have a swf 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.swf`
- `cargo run --release --package=exporter -- path/to/file.swf path/to/screenshots --frames 5`
## Structure
- `core` contains the core emulator and common code
- `desktop` contains the desktop client (uses `wgpu-rs`)
- [`web`](web) contains the web client and browser extension (uses `wasm-bindgen`)
- `scanner` contains a utility to bulk parse swf files
- `exporter` contains a utility to generate PNG screenshots of a swf file
## Sponsors
You can support the development of Ruffle via [GitHub Sponsors](https://github.com/sponsors/ruffle-rs). Your sponsorship will help to ensure the accessibility of Flash content for the future. Thank you!
