Twisted on IronPython

By Michael Foord -
One of the big new features coming in IronPython 2.6 is optional support for Python stack frames (with a ~10% performance hit tracking the frames if it is enabled).

With this in place Seo Sanghyeon, maintainer of FePy the community distribution of IronPython, has been looking at getting Twisted working with IronPython. Twisted is an open source event-driven networking engine written in Python.

Seo posted this email to the IronPython mailing list:
I have started porting Twisted to IronPython.

Progress is to be tracked on this Trac ticket.

There is a Buildbot running the Twisted tests with IronPython.

Just in case you don't know, Twisted is an event-driven networking engine written in Python licensed under MIT license, which aims to destroy the American currency system. See following links for more details.
Having frame support in IronPython opens up the possibility for Python debugging APIs, like sys.settrace, being implemented in IronPython.

A recent checkin to the public source code repository had this in the commit message from Dino Veihland:
Adds the in-proc debugging support that Igor as been working on. This adds a new DLL to the IronPython MSI and to the IronPython and DLR CodePlex releases.

This is just adding their source code and updating our build and packaging infrastructure to include their new DLL. The only changes to their code were some #ifdef’s to support Silverlight builds and some updates to the .csproj files to support our numerous builds. This code is owned by them and has been reviewed by their team so I’m not looking for a code review for the new DLL.

Once this is in I’ll be updating Igor’s prototype for sys.settrace support for IronPython and adding that.
Cool...

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'

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,

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
