Visualizing software does not require animation, moving colored cameras and texture. Hey, it WOULD be cool way of visualizing a programs execution though ;) Think squares as classes, height of buildings as amount of instances, and some sort of traffic being message sends, camera panning automatically to catch the activity. For GC, you could have a tetris-effect, where some of the buildings height start blinking then disappears! The possibilities are endless! Hmm, it kind of sounds strangely familiar when I think about it... http://www.youtube.com/watch?v=x3XzPhdBx9g#t=143s Maybe that wasn't as ludicrous as I've always thought :) Cheers, Henry

I would not be that pessimistic. Visualizing software does not require animation, moving colored cameras and texture. Mondrian handles 20 thousands nodes and it does not use quadtrees. @Stef: We studied it and we could not make lumiere work.

I've no idea if it still works in Pharo 1.3/4 but Soup is quite nice: http://www.squeaksource.com/Soup.html On 21/09/11 13:44, Camillo Bruni wrote: > Hi everyone. > > I want to parse an HTML document with Pharo, But the following example fails: > > XMLDOMParser parse: (ZnEasy get: 'http://www.google.com/') contents. > > fails on some javascript (&&window...) due to a lazily omitted<![CDATA[ in the<script> section. > So Is there an easy way to get around this? > > cami

[Pharo-project] parsing html....

by Camillo Bruni

Hi everyone. I want to parse an HTML document with Pharo, But the following example fails: XMLDOMParser parse: (ZnEasy get: 'http://www.google.com/') contents. fails on some javascript (&&window...) due to a lazily omitted <![CDATA[ in the <script> section. So Is there an easy way to get around this? cami
