The author is "nullPointer" who asked the question regarding I/O on the mailing list and announced the video [1]. The style of his message looks to me like he wants to stay anonymous for whatever reason and the project is (so far) closed source. Maybe it becomes a commercial or open source project. Only "nullPointer" is able to answer this ... I just wanted to know what the state of the project is. He has left a comment on my blog with some more infos (see [2]) Bye Torsten [1] http://lists.gforge.inria.fr/pipermail/pharo-project/2009-July/011176.html [2] http://astares.blogspot.com/2009/07/ui-builder-for-pharo.html -- Neu: GMX Doppel-FLAT mit Internet-Flatrate + Telefon-Flatrate fÃ¼r nur 19,99 Euro/mtl.!* http://portal.gmx.net/de/go/dsl02

[Pharo-project] KnownLands: a Class dependency explorer
by David Goehrig July 21, 2009

July 21, 2009

Hey Pharoers, I've been working on a little project for the past couple days, and now that I have something of a tangible result, I'm going to share the first screen grab. What I've been working on is a visualization tool for analyzing the relationships between Classes and the contents of their CompiledMethods. In the attached screen shot, the TPureBehavior circle in the middle is the root node, and all of the radial nodes are Classes referred to by the CompiledMethods associated with TPureBehavior. Each of these classes is bound to a literal in one of the CompiledMethods. The radius of the circle is directly proportional to the number of methods that Class has. IdentitySet has 2 compiled methods for example, whereas ChangeSet has 124 methods. Once I get collapsing working, and add some trace lines (so that when you've expanded and expanded and expanded it is obvious who is connected to who), I'll post this code somewhere. But what is incredible is how quickly things get really really deeply interconnected things get. Dave -- -=-=-=-=-=-=-=-=-=-=- http://blog.dloh.org/

[Pharo-project] Shall we forbid updating?

Hi, in the Pharo images I produce, there is a System->Update that never works. A lot of people are confused by it and don't know it only works on the core. Shall we remove this item from the menu?

[Pharo-project] GC limitations?
by Schwab,Wilhelm K July 21, 2009

July 21, 2009

Hello all, I have a weird-looking bug that I am willing to assume is my doing and in my code. That said, some debugging lead me to a situation I really do not enjoy: objects that I think should be gc'd are happily living in my image. I _think_ I have gagged workspace variables (they truly are more trouble than they are worth). Dolphin sometimes has "zombie" views that can lurk in a broken/invisible state but still hold onto other objects. Is there anything like that here? I know about the various #become: tricks, and do not like to resort to them; I would like to understand what is holding onto the would-be garbage. Can the Squeak/Pharo gc collect objects with cyclic references? Is there anything else comes to mind when hunting for objects that just won't go away? Bill
