Pygments for Windows Live Writer

By Michael Foord -
Pygments is an extremely versatile Python library that does syntax highlighting. It not only supports many input languages, but can also output in many common markup formats (for wikis and so on).

Windows Live Writer is a WYSIWYG Windows blogging tool by Microsoft. It allows you to write blog entries on your desktop (shock news - not everything needs to happen online), including adding images and videos. It integrates with blog services like Windows Live, Wordpress, Blogger, Live Journal, TypePad, and many more. I've never used it, but hear good things about it from developers I respect.

Devhawk (Harry Pierson the Microsoft IronPython PM) uses live writer, and has written a plugin that uses IronPython and Pygments with a Windows Forms multi-line textbox as the code editor window.
Pygments for WL Writer is a smart content source. In WL Writer’s terminology, that means when you click inserted text in the editor window, it is treated as an atomic entity which you can then edit by using the Edit Code button in the Pygments for WL Writer sidebar editor. I I often found that I would edit my code multiple times – usually to shorten lines so they’d fit on my blog without wrapping. CodeHTMLer for WL Writer is a standard content source, so it just spews the formatted code as HTML onto the page.

From an IronPython perspective, there’s some interesting stuff there. I decided to compile the pygments library into a DLL for easier distribution. If you look in the source, there’s a folder for the Pygments source as well as the parts of the standard Python library that Pygments depends on and my custom HTML formatter. Those all get compiled via a custom script which can be called by the build.bat file in the project root.
As usual this project is available for download from Harry's Skydrive. The source is up on Github. There are plenty of features he is thinking of adding, so if you use it don't forget to give him feedback.

In a separate post he notes an update he has made (download URL is unchanged).
The only change is that I now override OnSelectedContentChanged in the sidebar control. That way, if I have multiple blocks of pygmented code in a given post, the sidebar UI updates with the correct language and color scheme of the currently selected code block.
Quite a few of Harry's projects are up on GitHub. Harry has enabled issue tracking so that you can now submit issues, bugs and feature requests:
Speaking of GitHub; ipydbg and IronPython-URLs got a nice shoutout on the GitHub blog:

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...

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, ...
