Bridge, Kamaelia and XMPP on IronPython

By Michael Foord -
Kamaelia is a Python concurrency library that uses Python coroutines (generators). Despite being pure Python it is powerful enough for streaming audio and video. Bugs in IronPython 1 prevented Kamaelia running on IronPython, but that doesn't seem to be the case for IronPython 2...

Sylvain Hellegouarch has a Python library called headstock for communicating over XMPP:
For a while IronPython had severe shortcomings that prevented it running simple Kamaelia applications. Today I was able to run a simplechat demo using a vanilla IP2 on Windows with only one single modification to the logging module (thanks Seo). To be honest I didn’t expect it to go through :)

The chat demo is simple enough but means more complex examples using XMPP PubSub will work as well (they are all based on the same framework).

Now this isn’t production ready or anything. For instance the TLS support is broken (hopefully something easy enough to fix) so you won’t be able to connect to Google Talk for now.

Moreover I’m not sure the code is that fast considering how I had to simulate an incremental XML parser atop System.Xml (this allows for a XML stream to be parsed without requiring the full document or even fragment to be read first).

This is a great news for me because it means I’ll be able to move ahead with more work using IronPython 2.

Extending Abobe Flash Player and AIR with Python and Ruby

By Michael Foord -
An intriguing blog entry about an Adobe experimental project. It is a C/C++ cross- compiler for the flash player and AIR. This means that you can (will be able to?) cross-compile the Python / Ruby/ lots of other language runtimes and then run them in Flash. The blog entry contrasts this approach to the DLR which requires the re-implementation of dynamic languages - hence IronPython and IronRuby. The project is already beyond proof-of concept, they even have Quake III cross-compiled and running in Flash. Extending Adobe Flash Player and AIR with C/C++ Cross-Compiler Quake 3 has already been ported to managed code , but this is even more impressive. Whether the Python interpreter can be cross-compiled to run on top of another runtime (with completely different basic types), without changing the language semantics at all, has yet to be proved - but it is a very interesting project. (It also means that Python/Ruby will possibly be enabled only by additional optional downloads - but don'

IronPython Tools for Visual Studio CTP3

By Michael Foord -
At PyCon this year Dino Veihland announced IronPython Tools for Visual Studio, an extension to Visual Studio 2010 for working with IronPython. It features Python syntax highlighting, awesome auto-complete (intellisense) and a host of other features for working with IronPython code in Visual Studio. It can be used with the free Visual Studio shell and doesn't require you to own a full copy of Visual Studio. The third CTP (Community Technology Preview) has been made available for download. IronPython Tools for Visual Studio We are happy to announce a minor update to the IronPython Tools for Visual Studio.  IronPython Tools for Visual Studio (IPyTools) is a set of extensions available for Visual Studio 2010 which supports development of IronPython applications.  This release is our 3rd Community Technical Preview (CTP) and builds upon the previous two releases.  The release is a minor update which includes bug fixes and a number of small features.  You can download the latest rel

Further Adventures of the Debugger

By Michael Foord -
Harry Pierson (Microsoft IronPython PM) has been experimenting with writing an IronPython debugger ( ipydbg ) on top of the .NET MDbg APIs. When we last left him , he had implemented Just My Code (JMC) support allowing you to step into IronPython code. Since then he has made a lot of progress including a colourful REPL (interactive console) and solving some difficult problems around getting to real values behind boxed IronPython variables (needed for showing local variables). He has blogged extensively on what he has been up to (more recent posts last): Showing Source Code Colorful Console IronPython ConsoleColorMgr (the colorful console code pulled out into a separate IronPython module) A Little Hack...err...Cleanup Getting Local Variables Displaying Values Command Routing Getting Arguments REPL Console A lot of functionality is now present. In the command routing entry Harry outlines the seven commands supported by the debugger so far: Continue, Quit, Show Stack Trace, Show Locals,
