IronPython URLs

PyCon 2010 was great fun, and included several talks on or including IronPython. Python in the Browser This is Jimmy Schementi's write-up of his talk on using Python in the Browser, with links to the video and slides: You, the Python developer, use Python because you want to, but in the browser you use JavaScript because you think you have to. With IronPython you can write browser code in Python. I’ll only begin to answer "what can the browser bring to Python?" and "what can Python bring to the browser?" in this short overview; examples will be very simple (with the exception of a few flashy ones) to make sure you can get started immediately. IronPython Tooling The video of Dino Veihland's talk on the new integration of IronPython with Visual Studio 2010. The integration, which works standalone with the Visual Studio extensibility shell or integrated into VS 2010, is alpha quality - but has lots of nice features for IronPython development. It includes...

PyCon 2010 , the annual international Python conference is coming soon (February 17th 2010 in Atlanta US). The schedule of talks is now up, and as usual there are several IronPython related talks . 67. IronPython Tooling  By Dino Veihland, core IronPython developer: One of the most popular requests for the IronPython team is tooling support. During this talk I’ll show you some of the existing tools available to help create IronPython applications. I’ll also look at the latest IronPython features which can help you debug, profile and improve your applications. I’ll also compare and contrast these with the solutions available for CPython that you may already be familiar with. 71. Python in the Browser By Jimmy Schementi (Microsoft program manager for IronPython / IronRuby Silverlight integration): You write your server code in Python because you want to. You write your browser code in JavaScript because you have to. But with IronPython and Silverlight, you can write your brows...

More IronPython and DLR related projects, articles and news from around the web. IronPython in Visual Studio 2010 Screenshot of syntax highlighting  Visual Studio 2010 doesn't come with IronPython support out of the box, but it does have extensive APIs for writing your own extensions. Jeff Hardy has taken up the challenge and has written a set of IronPython extensions for Visual Studio 2010 with syntax highlighting, regions etc. The project has binaries available : " Just double click the .vsix file to install. " StackOverflow DevDays Cambridge Review Diary of a schwag hag Cambridge Stack Overflow Dev Days At the end of October I attended the StackOverflow DevDays in Cambridge UK and spoke on Python and IronPython. I demonstrated .NET integration with IronPython by creating a simple Windows Forms application at the interactive interpreter. This was followed by going through Peter Norvig's Python Spell Checker as an example of concise Python code. Thanks to Ne...

More IronPython and DLR related projects, articles and news from around the web. Small PIL for IronPython  One of the disadvantages of developing with IronPython, particularly for using existing libraries and codebases, is that C extensions don't work. One possibility is to use Ironclad , a C extension compatibility layer by Resolver Systems. Another one is to find or create a compatible API using .NET libraries. An important C extension in the Python world, virtually ubiquitous where images are used and manipulated, is the Python Imaging Library . All sorts of other projects (Django and Reportlab for example) use PIL, causing problems for using them from IronPython. A Japanese blogger has * started * to solve this problem by creating an IronPython project called "small pil" implementing part of the PIL API for IronPython. Changes to Dialogue Script in December 2009  i-Dialogue is a "Customer Experience Management" application by Cubic Compass. It is relev...

Another collection of blog entries and articles related to IronPython and the Dynamic Language Runtime. Commerce Server 2009 Product Query via IronPython A blog entry from Charles Medcoff with a nice example of writing product queries for Commerce Server 2009 (the Microsoft e-commerce platform) with IronPython, including the necessary app.config magic to get it to work. SharpDevelop 3.1 Released   SharpDevelop is a .NET IDE for Windows with excellent support for IronPython in its latest version. This release is the final version of 3.1, which includes the new IronPython support (including forms designer and debugger): Seven months after the 3.0 release comes version 3.1 – the last feature release of the 3.x series. The following high-profile features were added to SharpDevelop: IronPython Windows Forms Designer Debugging Support for IronPython Applications Profiler for Managed Applications The Future: 3.1.x and 4.0 SharpDevelop 3.1 is a long-term stable release branch ...

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...

Last year Jonathan Hartley delivered a talk at the Øredev conference on IronPython and dynamic languages on the .NET framework . A video of his talk is now up on viddler: Øredev 2008 - Cool Languages - Pumping Iron: Dynamic Languages on .NET Pumping Iron: Dynamic Languages on .NET Jonathan Hartley, Resolver Systems , UK As you may know, Microsoft is developing IronPython and IronRuby, .NET implementations of the popular open-source programming languages Python and Ruby. While it's clear that Microsoft wants to attract existing Python and Ruby developers to .NET, the role of IronPython and IronRuby for existing .NET developers is less clear. What value is there for a .NET developer in learning IronPython? What are the tradeoffs between IronRuby and a more traditional .NET language like C# or VB? Jonathan also took some pictures at the conference.

Yet another selection of blog entries and articles relating to IronPython from the last few weeks. Upcoming Presentations - Summer Edition The Coding Geekette (Sarah Dutkiewicz) is a regular at .NET and Python conferences speaking, amongst other things, about IronPython. In this blog entry she lists her forthcoming talks: Cleveland .NET group (Python 101 for .NET developer) PyOhio 2009 (Pumping Iron into Python + IronPython Show & Tell) devLink (going cross-platform with C#) There is also quite a bit of IronPython content at the forthcoming EuroPython 2009 in Birmingam (28th June to 4th July): an IronPython tutorial , ArcGIS and IronPython talk , Introduction to IronPython talk , Ironclad talk and a general Python VM panel discussion . IronPython and XHTML A Japanese blog demonstrating how to load and save XML from IronPython - using the .NET APIs and working with namespaces. In this case he is iterating through a directory of XHTML files and adding valid namespace declarations...

IronPython 1.0, a complete implementation of Python for the .NET framework, was released in September 2006. The first IronPython 2.0 release (Alpha 1) came in April 2007. IronPython 2.0 was built on the new Dynamic Language Runtime (DLR) which was a framework for implementing dynamic languages in general, which had been abstracted out of the IronPython 1.0 release. Along with the new IronPython 2.0 project IronRuby was announced. IronRuby was an implementation of Ruby for .NET, led by John Lam who had previously been involved in the RubyCLR project. It has been a long road for IronRuby, with the latest release version 0.5. IronRuby 1.0 at OSCON 2009 Following their tradition of conference driven releases (panic-driven-development?) IronRuby 1.0 will be released at the coming OSCON 2009 conference: IronRuby is 1.0! Come and see how IronRuby is used in .NET programs, how well it performs, and how conformant it is. IronRuby is an Open Source implementation of the Ruby programming langu...

TechEd 2009 (Microsoft developer conference) is come and gone, but dynamic languages played a bigger part there than ever before and John Lam (IronRuby commander in chief) has blogged about his presentation. He has been working on interesting twists on the REPL; the Read-Eval-Print-Loop otherwise known as the interactive interpreter. He demonstrates one that can switch between DLR based languages (IronPython and IronRuby) and is an editor as well. The story for dynamic languages in Visual Studio is not massively impressive, but you can get good results with Wing or Netbeans , SharpDevelop has excellent IronPython support and there is also the editor built into the very interesting Pyjama Project . With the Microsoft dynamic languages team getting interested in editors perhaps the future is brighter for a supported Microsoft IDE for IronPython and IronRuby? Dynamic Languages at TechEd 2009 Dynamic languages on .NET are picking up momentum at this year's TechEd. Your typical Tec...

PyCon 2009 is now long over, and I'm still recovering from the aftermath. This year IronPython played more of a part than ever before. There were several IronPython related talks, all of which were recorded and are already up on the PyCon Video Channel : IronPython: Directions, Data and Demos Jim Hugunin's talk on the status and future of IronPython, including how IronPython has affected the Common Language Runtime and C#. Come learn about our secret plans to use IronPython to take over the world. The emphasis will be on demos showing the seductive possibilities that IronPython enables for Python developers. These include taking advantage of the newest features in Windows 7, running your Python code in the browser with Silverlight, and many more. IronPython Implementation Dino Veihland's talk on IronPython's innards - including demonstrating executing Ruby code from inside Python. IronPython is an implementation of Python running on .NET. This talk will provide an over...

We've had a great time at PyCon and I'm still here in Chicago on the last day of the sprints. The whole event, from language summit through conference through sprints, was pure awesomeness and IronPython was right at the centre. There is also exciting news about IronPython in Action, but all of this will have to wait. In the meantime there are a couple of IronPython events happening soon : Geek Night @ Thoughtworks: IronPython, Ruby in C#, DVCS 4th April Geek Night at Thoughtworks. Three discussions: IronPython Writing Ruby like code in C# Distributed Version Control Systems When: Saturday, 4th April, 2pm onwards Where: Thoughtworks, GF-01 & MZ-01, Tower C, Panchshil Tech Park, Yerwada Registration and Fees: This event is free for all to attend. The IronPython talk is from Aroj George: Aroj will take you through some cool ways you can use the power of Python in the .NET world. This talk includes a demo of embedding an IronPython engine in a .NET application to enable intera...

PyCon 2009 - the international Python conference in Chicago - is rapidly approaching. Harry Pierson (Microsoft IronPython Program Manager) has blogged about how IronPython features this year: IronPython at PyCon Michael Foord and Jonathan Hartley are running a Developing with IronPython tutorial . Michael is also delivering a talk Functional Testing of Desktop Applications . Jim Hugunin is delivering an invited talk IronPython: Directions, Data and Demos Dino Viehland is sitting on the Python VMs panel and doing a talk IronPython Implementation Sarah Dutkiewicz (aka Coding Geekette) is doing a talk Pumping Iron into Python: Intro to FePy Harry also mentions the difficulties he's had in getting the Microsoft Gold Sponsorship for PyCon actually into the hands of the PSF. (Python Software Foundation - who as well as running the conference also own the copyright on the Python code and the trademarks etc). As well as talks on tutorials covering IronPython, PyCon starts this year with...

The talk schedule has gone up for for PyCon 2009 in Chicago. There are three talks on IronPython, plus a tutorial on the Wednesday before the conference. PyCon is the international Python conference, and the highlight of the Python year. The conference dates are: March 25-26th Tutorial Days March 27-29th Conference March 30th - April 2nd Development Sprints Jim Hugunin is one of the invited speakers, so his talk doesn't yet appear on the schedule - but his usual talk is " IronPython the Road Ahead ". The other two IronPython talks are: IronPython Implementation, by Dino Veihland (core IronPython developer) IronPython is an implementation of Python running on .NET. This talk will provide an overview of the IronPython internals. The talk will start with a high-level walk through of the IronPython architecture and source layout. From there we’ll drill into details such as method dispatch, how the .NET and Python type systems interrelate, multi-runtime support, and how I...

The esteemed Mr Tartley recently stepped into the shoes of Harry Pierson (Microsoft IronPython PM) and spoke about dynamic languages on the .NET framework at the Øredev conference in Malmö, Sweden. He has posted the slides and notes online, based on Harry's presentation but delivered with Jonathan's irrepressible style (and with the audience's reaction inline). Pumping Iron: Dynamic Languages on .NET The talk is an exploration of the differences between static and dynamically typed languages, plus some of the specific language features of Python and IronPython. My favourite part is where he discusses the cost of compile time checking. Those who advocate the benefits of statically typed languages often discuss what losing compile time checks costs, what they don't talk about so often is what keeping them costs: " So let’s examine what we’re really talking about losing when we have no compile-time type checks. As we’ve noted, type safety really does catch and elim...

This post is a bit late - in fact this news was announced several months ago at this year's Microsoft Professional Developer's Conference . At the PDC the Dynamic Language Runtime was demonstrated - along with the news that it will be part of .NET 4.0. Both Visual Basic 10 and C# 4.0 will have dynamic elements that make use of the Dynamic Language Runtime. In a blog entry after the conference Jim Hugunin links to Channel 9 videos of his talk on the DLR and Anders Hejlsberg's talk on the way C# is changing. Dynamic Language Runtime Talk at PDC C# 4 will allow you to use objects dynamically through a new static declaration. A new keyword that allows you to statically declare dynamic objects! Objects that are declared as dynamic will have operations on them (attribute lookups, method calling, indexing, numerical operations and so on) done through the DLR. The intarwebz were awash with the news. Here is a selection of the most interesting and informative responses that I foun...

Several reports on talks on IronPython and dynamic languages from the Microsoft TechEd conference (New Zealand) and Microsoft Technology Summit. Scott Yang liked harry Pierson't talk at TechEd: The final show today was the highlight — “Pumping Iron: Dynamic Languages on .NET” where Harry Pierson talked about the benefit of dynamic typing languages and why they are useful to .NET users. Great presentation, and great arguments on why the lack of compile time checking is NOT really an issue. IronPython was used in the code example, which is something I am a bit familiar with. Jamie Penney's notes on the same talk: WEB305: Pumping Iron: Dynamic Languages on .Net - Harry Pierson Tradeoff between Type Safety and Flexibility Rails ActiveRecord example - AR adds the column names of a table as properties on the model class at run time. Real products are being shipped on IronPython - Resolver One Dynamic languages are very productive - good for initial work on greenfield pr...

It's only a few days until PyCon UK . Christian, Menno and I have been preparing the IronPython tutorial and there is new information on the wiki about what you will need if you are attending. IronPython Tutorial on the PyCon UK Wiki Page We will support IronPython on Linux, Mac (both via Mono) or Windows - and you get to take your pick of four different databases. During the tutorial we will work through creating a windows forms based Twitter client called Twatter . There are more details on my blog, along with a screenshot of it running on the Mac and a screenshot of the example application for the early chapters of IronPython in Action . Twatter and MultiDoc on Mono Windows Forms Since I wrote that entry Christian has done some more work, and Twatter now fetches images of tweeters. Here's a screenshot of it running with IronPython 2 and Mono 2.0 preview 3 on the Mac:

The PyWorks 2008 conference schedule is now up. This is a new conference, held in Atlanta November 12th-14th, by the same people who bring us the Python Magazine . I'll be speaking at PyWorks on IronPython: Python on .NET and in your Browser. PyWorks 2008 Conference Schedule I'll also be at the UK Python conference (along with most of the Resolver Systems developers) in Birmingham September 12-14th. Three of us (Christian Muirhead, Menno Smits and I) will be giving a half day tutorial on Developing with IronPython (on the Friday morning). In this blog entry I talk about the sample application we'll be building together in the tutorial (come with IDE and ready to code) - plus a call for volunteers for the conference itself: PyCon UK: IronPython Tutorial, Socials and Volunteers Needed " The tutorial is based around a simple Twitter client, which Menno has named Twatter! We've been testing Twatter on Windows, Linux and the Mac (it doesn't look bad on the Mac). ...
