Mono can now compile IronPython 2.0

By Michael Foord -
If you follow this blog, or the state of IronPython on Mono, you will know that the version of IronPython included in Mono (from the FePy project) is quite out of date. This is because (for various reasons) Mono has been unable to compile IronPython 2.0 from source which has prevented a new FePy release.

This causes a problem with running the IronPython in Action examples from Mono and I wrote a blog entry about how to work around this:
The intention is that MultiDoc, along with as many examples from the book as possible, run on both Mono and the .NET framework; IronPython isn't just for Windows but can also be used on Linux and Mac OS X or anywhere that Mono will run.

Some readers have reported that MultiDoc crashes on exit when run with Mono. The root cause of this is the old version of IronPython 2 that ships with Mono.

...

This is reason enough to look at using a more recent version of IronPython 2. Even though IronPython can't be compiled with Mono you can still use the up to date Windows binaries (which is part of the point of Mono - binary compatibility). To use the latest version of IronPython (2.0.1) you'll need Mono 2.4 or more recent...
However there is good news on this front. Ankit Jain recently posted the following to the Mono development email list:
Current xbuild status:

It can handle solutions (.sln) now, thanks to Jonathan Chambers, with C#, VB.net projects. Handles embedded resources, satellite assemblies, project references etc.

Eg. Paint.Net 3 ( builds completely with it now, IronPython (2.0.1) builds, IronPython svn (builds with compile time errors) etc.

Only .net 2.0 projects are supported currently though. I will start adding support for newer versions very soon, also ASP.NET, Silverlight etc projects.

This is part of the mono 2.4.2 release and is a *big* improvement over xbuild in the last release. Would be really helpful to get feedback and bug reports on this :)
In his status update Seo Sanghyeon (FePy maintainer) did report that IronPython 2.6 trunk could be built with Mono, so it looks like a recent checkin has broken Mono compatibility - temporarily I'm sure. However, the news that Mono can now compile IronPython 2 is great and hopefully means that a FePy update will follow on shortly.

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
