John Gossman's observations on Avalon development

On the topic of the previous post, we had long debates at Asymetrix about C++ versus OpenScript , and there were similar issues when AutoCAD switched from AutoLisp to C. I coined the term "Seductive Programming" to describe the way tools are marketed Read More...

I know Chris isn't implying dynamic languages are only for hobbyists, but any discussion of languages quickly starts to sort them for their attractiveness to developers on a scale from "hobbyist" to "professional developer". Why? This is a deep subject, Read More...

Chris and I met with Jim Hugunin this morning and got an overview of the IronPython architecture. Which is basically, very simple and straightforward. Like you might expect, it consists of a tokenizer, a parser, a code generator and a library of built Read More...

Rather than push on embedding Python in XAML, which Chris has made fine progress on anyway, I changed tack and quickly got Python code behind working. Separating code and markup is considered best practice anyhow...and the implementation was trivial. Read More...

While I'm trying to work around the xml:space issue from my last post, it is worthwhile to see how simple it was to create the attached property (which works fine, as long as your script doesn't need newlines...): namespace Pythalon { using System; using Read More...

I took a slightly different tack than Chris on embedding Python into Script . I created an attached property, with the idea that I could set a piece of script "on" an element, giving it some scope. For example, I got this to work: < Button Name = " Read More...

The book I used to learn Python is also available online: http://diveintopython.org/ I recommend buying the lump of paper, to reward the author for a good piece of work...but on-line is nice too. Read More...

Looking at the last point on its own grounds, you may think: "Okay, you can program Avalon in Python. So what? I'm a C#/VB/C++ programmer...I need to learn Python why??" The reason Pythalon is so fun is that it is interactive. The programs in the previous Read More...

This weekend I continued my experiments with Python and Avalon. Before I was hosting Python in an existing app, but now I've started from almost scratch. I have to clean up the code and wait for the outside world to get new Avalon bits, but I can describe Read More...
