Dare Obasanjo has created an IronPython command line client for google reader. This is a first step in integrating RSS Bandit with google reader : Command Line Client for Google Reader in IronPython

A few recent blog entries featuring or mentioning IronPython: CALEBLOG: Garbage Collecting 2007 - a blogger includes being surprisingly interested by IronPython and the DLR in his mental garbage collecting of 2007. Python.NET - Alcides Fonseca is a fan of both .NET and Python. He likes IronPython, but prefers Python.NET. Playing with the DLR - Rainer experiments with the DLR. He shows code for executing IronPython, IronRuby and Managed JScript scripts by embedding the DLR (from IronPython 2) in C#. Mood News - Now IronPython Powered - Davy Mitchell's ' Mood News ' is now powered by IronPython Oh, and there are some more IronPython Cookbook updates: Launching the Browser - launching the system default browser with a specific url (includes cross platform notes) Access Unmanaged Code with Dynamic P/Invoke - an example of using the FePy implementation of ctypes for IronPython Parsing RSS - IronPython code for parsing RSS feeds

Another one in Japanese I'm afraid, but again the code is clear. This blog entry shows how to use WiimoteLib , a Managed Library for Nintendo's Wiimote, from IronPython: Using the Wiimote from IronPython

Another example of WMI with IronPython (this one querying the BIOS): ARTYPROG: wmi - IronPython There are now four examples of WMI usage on the IronPython Cookbook WMI Pag e .

A Christmas eve post on putting a Python console into XNA games: Learning XNA: Put a Python in Your Game UPDATE: link updated to new location - now with video and source code available !

There have been some great new additions to the IronPython Cookbook in recent weeks: Creating XML Trees - Using XML to LINQ features, that are new to .NET 3.5, with IronPython File as TextReader - a wrapper class, so that you can use Python files where .NET expects a StreamReader object Extremely Late Binding - Late bound COM with IronPython MonthCalendar Control and datetime - Using the Windows Forms MonthCalendar control with Python datetime Listing Time Zones - Listing time zones known to the system Using Spreadsheet Functions with Excel 2007 - more COM Listing all Exceptions in the System Plus the IronPython 2.0A7 files have been added to the Downloads page.

You may struggle to read this unless you're Japanese, but the code and screenshots speak for themselves: IronPython on Mac OSX and Mono

Three links in one post! IronLisp becomes IronScheme The announcement is on the xacc.ide blog . Comparing IronPython and CPython R Tyler Ballance runs Pybench for CPython and IronPython (on Mono). This was discussed back in April, which included a useful comparison of .NET and Mono performance . Big in 2008: Dynamic Languages Atop High Level Languages A look forward to the future of dynamic languages in 2008, including the trend of implementing dynamic languages on top of high level languages.

IronPython 2.0 Alpha 7 (source and binary) is now available: IronPython Project Homepage Release Notes and Download Major points of interest with this release: IronPython 2 should now be PEP 342 compliant (yield should now be fully compatible with Python 2.5) This is the last release to be built and fully tested with Visual Studio 2005 Around twenty bugs (mainly minor) have also been closed with this release.

Mike Stall has an interesting new blog entry on the difference between C# and Python regarding returns in finally blocks: Return vs Finally Did you know that returns in finally blocks swallow exceptions in Python? (I didn't): >>> def f(): ... try: ... raise Exception('ouch') ... finally: ... return 3 ... >>> f() 3 >>>

Kam-Hung Soh, a blogger from Australia (which should please my colleague Christian), has written a blog entry showing simple 'Hello Windows' scripts in both Jython and IronPython: IronPython and Jython Hello Windows He notes " Both implementations allow setX functions in object constructor's argument list ", which is unsurprising as both implementations are the creation of Jim Hugunin.

Continuing the 'natural sort' meme floating around the blogosphere at the moment, Dare Obasanjo compares natural sort code in IronPython and C# 2.0: Natural Sort in IronPython vs. C# 2.0 Unsurprisingly, IronPython is slightly more concise...

IronPython Studio is a free full IDE (Integrated Development Environment) for the Python programming language. It is based on the existing IronPython example that is included in the VS SDK. IronPython Studio IronPython Studio is based on the Visual Studio 2008 Shell runtime (royalty free) and can be installed without requiring any version of Visual Studio. It is hosted on codeplex. Installer, source and screencast are available from the download page . The sources require Visual Studio 2008 (Team Edition apparently) and the SDK. NOTE: Some users (myself included) had trouble getting this working. The magic steps are: Download and install the Visual Studio X redistributable from: Visual Studio Extensibility After you run the Install for the MS VS 2008 Shell Isolated Mode Redistributable, you must then go to the folder (" C:\VS 2008 Shell Redist\Isolated Mode ") and click on: " vsshellisolated_enu.exe " to actually install the redistributable runtime. Install IronPyt...

The audio recordings for PyCon 2007 are finally making their way out. Jim Hugunin's talk is now available: IronPython Present & Future PyCon 2007 Audio Recording IronPython is an implementation of the Python language targeting the Common Language Runtime. IronPython has excellent performance, seamless integration with the .NET platform and very high compatibility with the standard Python implementation. The first public talk on IronPython was at PyCon 2004, three years ago. Since then, IronPython has progressed from a rough prototype to a 1.0 release with a vibrant user community. This talk will present the current state and future directions of this Python implementation.

After two years of work, Resolver One - the IronPython programmable spreadsheet, has reached public beta. You can download it now and have a play: Resolver One Public Beta Now Live Resolver is a " rapid application development tool with a familiar interface ", and should be useful to power users of spreadsheets and anyone who crunches numbers with Python. The Resolver Hacks website with articles and examples is in the process of being updated to use the new API that this beta introduces. Today three of us from Resolver were interviewed by Robert Scoble today. He is on his way to Le Web conference in Paris, so I don't know when the actual video will appear - but I'll be sure to let you know.

Microsoft Live Labs have announced a new project - the Volta Recompiler: Volta on Live Labs As far as I can tell, this allows you to compile IronPython (and other .NET languages) to Javascript: Microsoft Live Labs Volta helps developers who build distributed applications on the .NET platform, using the Microsoft development stack (programming languages, libraries, and Visual Studio). This version of Volta supports applications that run on the Microsoft CLR, a JavaScript-enabled browser, or a combination of the two. ... In essence Volta is a recompiler. Volta works on MSIL rather than on a textual source language. Volta rewrites MSIL into any number of target languages, including, today JavaScript and MSIL itself. ... In summary, Volta confers flexibility in the architecture dimension through: Language-independence . Write Volta code in any language that compiles into MSIL. For example...

Miguel de Icaza has a blog entry responding to an article on 'Mono Usage in the Enterprise': Mono Usage in the Enterprise It has some interesting comments on the role of Python in the Gnome project and IronPython and Boo on Mono: Python is indeed making great strides as a desktop development platform and am not sure that we are in the business of competing with it. If people like writing Python code, they should just keep writing python code. Myself, I like the IronPython variation of Python more. IronPython just happens to be JITed Python and in most tests it is faster than CPython. For the past year or so, we have also been in love with Boo , another .NET language. Boo has support for strong typing, so for certain scenarios you will get even better performing code (basically, when you can determine the type of a variable ahead of time, instead of having the variable be entierly late bound).

Through Mono IronPython can be used to create cross platform applications, but the story for desktop applications on platforms like OS X has never been particularly compelling. Miguel de Icaza outlines the future for Mono on OS X (one of the outcomes of the Mono summit), including easy access to the MonoDevelop IDE and screenshots of a winforms application on OS X using the native drivers! Mono on OS X and Win32

Kamil Dworakowski (a Resolver developer) explains an obscure bug with comparing lists in IronPython 1, and how it cost him a can of coke: IronPython Bug that Cost me a Can of Coke The bug relates to IComparable and value types in the underlying framework and how IronPython implements equality in an attempt to remain faithful to Python.
