IronPython URLs

Devhawk, otherwise known as Harry Pierson, is the program manager for IronPython on the Microsoft dynamic languages team. He is a prolific, even more than me, has a whole bunch of interesting IronPython related posts that I've fallen behind on. The first set of posts is about building a hybrid Python / C# application, specifically using the awesome Pygments syntax highlighting library from a .NET application. Pygments for Windows Live Writer v1.0.2 Harry has been working on a syntax highlighting plugin for the Windows Live Writer desktop blogging tool. He's using Pygments via IronPython 2.6 Beta 2 to do the highlighting, and barring some problems with the import magic Pygments does (known by the IronPython team as “Harry’s Pygments Import Bug”) it works fine with IronPython. Building a Hybrid C# / IronPython App without Dynamic Type C# 4.0 introduces a new feature, the dynamic type, that will make embedding and interacting with dynamic languages from C# much easier. If you w...

Another selection of articles on IronPython from the last few weeks. Scripting: Reliably Finding my 32bit EXEs on a 32bit & 64bit OS or Where is IronPython? Saveen Reedy has a problem finding IronPython. More to the point he has an issue reliably finding the installed location when using both 32bit and 64bit versions of Windows (which have different standard install locations). Iron Python: How to talk to the .NET Framework A short blog entry demonstrating how IronPython integrates with the .NET framework by creating a simple GUI with Windows Forms and the interactive interpreter. The steps are virtually the same as I use when demoing IronPython to a .NET crowd. Creating Python Modules from CSharp This one is a bit meta, but still useful. It's a recipe I put on the IronPython cookbook and shows a 'slightly-different-from-the-usual' way to integrate C# with IronPython. It shows how you can use C# to programmatically create Python modules for use from IronPython. Back to ...

Only the finest selection of articles and blog posts on IronPython and related topics.

Kudos to Vernon Cole Dave Fugate, IronPython testing and infrastructure guy, pays homage to Vernon Cole for pywin32's adodbapi which runs under both CPython and IronPython. The tests have now been added to the IronPython test infrastructure so that the IronPython team will get early warning if they break it. Dave comments " Now I just need to setup Northwind databases on 40+ test machines... ". Self-executable scripts A...

Another selection of recent posts on IronPython related subjects. All the posts in this mix are by Harry Pierson and Davy Mitchell ! First, DevHawk (Harry Pierson) has some comments on recent IronPython releases. AgDLR 0.5 This is the Dynamic Languages SDK for Silverlight that recently had a refresh for Silverlight 3. In this post Harry discusses XapHttpHandler , an ASP.NET handler for IIS that can dynamically build dynamic applications using Chiron. He particularly likes this feature as he wrote it! XapHttpHandler does the same exact on-demand XAP packaging for dynamic language Silverlight applications that Chiron does, but it’s implemented as an IHttpHandler so it plugs into the standard ASP.NET pipeline. All you have to do is put the Chiron.exe in your web application’s bin directory and add XapHttpHandler to your web.config IronPython 2.6 Alpha 1 Something else that got releases recently was the first alpha of IronPython 2.6. This version of IronPython will target Python 2.6, ...

A few months ago I got behind on posting interesting IronPython related links. I've caught up a lot, but a whole bunch of interesting stuff happened in November and December that I haven't reported yet. Some of that will have to wait for another day, but we'll end the year with a selection of some of the snippets from the last couple of months.

Here are a collection of recent blog entries that feature IronPython but don't quite qualify for an IronPython-URLs entry of their own. Starting with two new pages on the IronPython Cookbook : Validating a Filename A short recipe by Davy Mitchell that ensures user input is valid as a possible filename, removing invalid characters. Profiling for Silverlight An entry by Dan Eloff demonstrating performance profiling for IronPython Silverlight applications. Steve Gilham has been doing some odd things. Notably creating Java libraries in Java and Scala and then running them on .NET using the IKVM cross-compiler. I haven't been tracking them on this blog because most of the experiments have only been tangentially related to IronPython, but his latest entry is interesting. Here he is writing Scala (a very statically typed language for the Java Virtual Machine) code and using it from IronPython: Scaling the tower of Babel II Which of course begs the question why ?... it's still c...

There are five new wiki pages, across three different wikis (well - perhaps two wikis and a pseudo wiki) about IronPython. There are three new pages on the IronPython Cookbook . People in IronPython A page on the different people in IronPython.

Two new recipes have been posted to the IronPython Cookbook . They are both about interacting with Active Directory from IronPython. ActiveDirectory and RefreshCache DirectoryServices to Dictionary The first article shows how to use ' System.DirectoryServices ' and ' RefreshCache ' to load attributes not exposed by ADSI. The second is a helper object that turns ' DirectoryService' objects into Python dictionaries, which are easier to work with.

Feihong Hsu (who is doing a talk on Python.NET at PyCon 2008 ) has added several new entries to the IronPython Cookbook . He has also updated more entries to make them compatible with Python.NET (or adding notes on ones that aren't compatible with Python.NET). New entries: Getting Images from the Clipboard Creating Multiframe TIFF Image Files Using the Webbrowser Widget Preview all Installed Fonts Basic Handwriting Recognition Preview all Installed Voices Speech Recognition WPF GUI Using XamlReader Those of you interested in trying Python.NET with .NET 2.0 SP1 may be interested in this blog entry by Feihong Hsu (with Windows Forms example code) on a Python.NET patch (with binaries) to make it work.

The IronPython Cookbook Downloading a Web Page recipe has been appropriately updated.

IronPython classes aren't true .NET classes, not least because you can swap out their base classes dynamically, add methods and have all sorts of dynamic fun with them if you really want to. There are ways to use IronPython classes from C# (and other .NET languages) though. This cookbook recipe shows one approach, which involves inheriting from a C# class: Using Python Classes from .NET
