Alchemy was designed to be a research project that allows users to compile C and C++ code that is targeted to run on the open source ActionScript Virtual Machine (AVM2). The purpose of this preview is to assess the level of community interest in reusing existing C and C++ libraries in Web applications that run on Adobe Flash Player and Adobe AIR.

With Alchemy, Web application developers can now reuse hundreds of millions of lines of existing open source C and C++ client or server-side code on the Flash Platform. Alchemy brings the power of high performance C and C++ libraries to Web applications with minimal degradation on AVM2. The C/C++ code is compiled to ActionScript 3.0 as a SWF or SWC that runs on Adobe Flash Player 10 or Adobe AIR 1.5.

Alchemy is primarily intended to be used with C/C++ libraries that have few operating system dependencies. Ideally suited for computation-intensive use cases, such as audio/video transcoding, data manipulation, XML parsing, cryptographic functions or physics simulation, performance can be considerably faster than ActionScript 3.0 and anywhere from 2-10x slower than native C/C++ code. Alchemy is not intended for general development of SWF applications using C/C++.

With Alchemy, it is easy bridge between C/C++ and ActionScript 3.0 to expand the capabilities of applications on the Flash Platform, while ensuring that the generated SWCs and SWFs cannot bypass existing Flash Player security protections.

Adobe is providing some example libraries, and developers are encouraged to share their ported libraries.

The Alchemy preview is prerelease software that is not supported by Adobe and may contain bugs. It is therefore advised that Alchemy not be used to generate code for use in production.

Alchemy is designed to bring the power of C and C++ libraries to Web applications. The goal of this research project is to enable Web developers to re-use the massive amount of existing C and C++ code and expand the capabilities of applications deployed on Flash Player or AIR. For the first time, developers can re-use existing code that has already been tested and do so in a way that is safe to run in the browser in the Flash Player sandbox.

It is ideally suited for computation-intensive use cases, such as audio/video transcoding, data manipulation, XML parsing, cryptographic functions, image encoding, PDF rendering or physics simulation.
