PyAMF blog

We’re pleased to announce a new release of PyAMF, a lightweight library that allows Flash and Python applications to communicate via Adobe’s ActionScript Message Format.

This release improves support for Google App Engine and introduces a new AMF gateway for GAE web applications. Aral Balkan announced he’s using PyAMF in his GAESWF project, which will be used to power the website of the online Singularity conference later this year.

You can try some of the PyAMF examples for GAE on our appspot like the Interactive Python shell example and the PUnit tool to run the PyAMF unit tests on GAE using a web interface. We also added an Ohloh API example.

The dependency on the fpconst module was removed for Python >= 2.5 to make it easier to deploy PyAMF applications on GAE and devices like smart phones. Unfortunately we had to keep it around for the Windows platform due to a float issue with that version of Python 2.5.

Check out the download page, installation instructions or the API documentation. Questions? First stop is the mailing list but we also hang out on IRC.

Google did the Ajax version of the Python shell, running on Google App Engine, we present you with the Flex version (click image to view the sample):

You can browse or download the source from the Subversion repository. You can find instructions on how to run the example yourself on the wiki page.

The 0.3 release tree has been mostly about building up compatibility with Google’s App Engine.

Because the environment that Google exposes to the developer is quite restricted (for obvious reasons!) we thought it best if we get the entire PyAMF test suite (up to 430 individual tests and counting …!) running.

We have built a simple web app that runs the PyAMF test suite from within the Google App Engine. Its a work in progress and isn’t planning on winning any beauty contests, but works nicely.

Check it out!

PyAMF is a lightweight library that allows Flash and Python applications to communicate via Adobe’s ActionScript Message Format.

AMF3 and RemoteObject are supported in all the implemented Remoting gateways, currently compatible with Django, Twisted, TurboGears 2, Web2Py and other WSGI supported web frameworks.

After Google’s announcement on Monday we received a lot of questions about running PyAMF on the Google App Engine so we decided to start working on a tutorial. This is a work in progress and might require some updates to the library. We’re also planning on setting up a demo site on our appspot but more on that later.
