Notable Blogs: Smalltalk meets Vista and .NET

Posted by: Jack Vaughan on July 21, 2006 DIGG
By Jack Vaughan
A recent addition to the list of notable blogs is Peter Fisk’s VistaSmalltalk blog. This Canada-based, long-time Smalltalk hand has set about to explore the ways in which the venerable Smalltalk programming language can work with Microsoft’s .NET classes using the Windows Presentation Foundation.

Fisk’s goal is to influence people ready to consider Smalltalk as a potential option to Microsoft’s XAML-and-C#-or-VB.NET approach to building rich Web interfaces using Windows Presentation Foundation. At the same time, he sees Smalltalk as a useful alternative to the recently touted – highly touted, in fact -- combination of XML and JavaScript known as Ajax [or Atlas].

Smalltalk advocate Fisk is interested in the fact that Microsoft’s Windows Presentation Foundation [WPF] is due to appear in a Windows Presentation Foundation-Everywhere [WPF-E] version, which is intended to run …well, everywhere; that means on cell phones, Xboxes, Macs, cell phones, and so on.

His efforts to create Vista Smalltalk, are described on his blog. He sees the .NET platform, replete with hundreds of thousands of methods that can be called, as an apt vehicle for Smalltalk. As he looked at WPF, he became interested in the notion that, if he could get Smalltalk to run within the WPF environment, “Smalltalk could run everywhere.”

Thus, he has built Vista Smalltalk in WPF. An objective is to capitalize on the thousands of available methods in WPF. And the ins and outs of actually fleshing out that process are depicted on his Weblog. He describes mapping issues, compiler service issues, type caching, and many more challenges.

Fisk credits WPF for its use of vector graphics as opposed to bitmaps for rendering to screens. These capabilities, he suggests, will become increasingly useful as computing continues to move off the computer – to cell phones, wall-type monitors and more -- much as Microsoft presently envisions. Smalltalk, he maintains, can have a role.

Between the Microsoft approach [based on programming languages it explicitly supports, combined with XAML, of which it is the primary advocate] and JavaScript, says Fisk, there is a middle approach that may turn out to be the best of both approaches.
