Hi! I had fun implementing a spring layout in mondrian. Try: -=-=-=--=-=-=-=--=-=-=-=--= | view | view := MOViewRenderer title: 'Spring layout example'. view interaction refreshLayoutEvery: 30. view shape rectangle size: 15. view nodes: (1 to: 30). view edges: (1 to: 30) from: #yourself to: [:v | v \\ 5]. view springLayout. view open -=-=-=--=-=-=-=--=-=-=-=--= A spring layout was my very first program in Smalltalk, about 10 years ago. It was fun to show it to Michele. Fortunately for me, he spoke French :-) In its actual state, the layout does not scale. If you have more than 100 nodes, it will become very slow. The algorithm complexity is quite bad. I had some ideas on making it a bit more scalable.

MOViewRenderer>> use of method clone

by Laval Jannik

Hi all, I try to use Moose in a pharo1.1. I have a small bug in Mondrian: It uses the method clone, which is no more defined in pharo1.1, To resolve the bug, I replace it by copy, but I don't now what are the ripple effects. With this, I do well a DSM. Cheers, --- Jannik Laval

About growing mushrooms in sahara and the little lesson around it.

by Stéphane Ducasse

Hi guys Since moose is a platform it is not obvious that you are forced to refer to it when writing papers. May be you are working on representing the evolution of mushrooms grow in sahara and your competitors will kill you if you do not cite their previous great and fabulous work on mushrooms drying in sahara sub-mediteranean. Now please not forget that you can model mushrooms often because you use Moose, so adding a reference to Moose, Mondrian and others is important too. More important that you believe so please remember it to yourself. Be nice with your friends. Because if you are only nice with your competitors then may be this is better after all but we do not share the same idea of life (and deontology). Stef one possible way to refer to moose is @incollection{Duca05a, Abstract = {Software systems are complex and difficult to analyze.

mcc download

by Marc Toussaint

Is there a place where 'mcc' (fact extractor that parses C/C++ code) can be accessed? I tried on the homepage of the LOOSE project, but it was not accessible. It also didn't seem to be a part of the MOOST suite or inFusion tools. (I am working on Ubuntu.)

Re: XML Parser / Pastell

Hi, I exchanged a number of emails with Jaayer and Norbert regarding some improvements of XMLSupport and its port to Gemstone.

There is indeed a slowdown. I am not sure where it comes from however. Executing twice "XMLParserTest new benchmark1" does not return the same result. Actually, it increases at each execution! I thought that a garbage collect before running the bench would help, does apparently it does not. Calling asSymbol on a symbol should not be perceptible I believe.

Missing dependencies in Moose

I wanted to load the last version of Moose to try Cyrille code, but I bumped into: This package depends on the following classes: MAMatrix MAVector MASymetricMatrix You must resolve these dependencies before you will be able to load these definitions: DudeBooleanMatrix DudeBooleanSymetricMatrix DudeBooleanVector Select Proceed to continue, or close this window to cancel the operation. -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Setting colors in Mondrian and sorting

by Alexandre Bergel

Hi! Here is a short script excerpt I use. view shape rectangle size: 10; fillColor: [ :aMethod | aMethod isCovered ifTrue: [ Color lightRed ] ifFalse: [ Color white ]]. view nodes: (aClass methods sortedAs: #isCovered). I feel the way the color is set is very verbose. The following are equivalent fillColor: { #isCovered -> #lightRed } fillColor: { [:m | m isCovered] -> #lightRed } fillColor: { #isCovered -> #lightRed . [:m | m isCovered not ] -> #white} The white color could be the default color is no color is picked up. In the script above, I also use #sortedAs: to sort my elements. I find this method quite handy. It is defined as an extension of Collection. It is more flexible than Jannik's #sortedBy: and Moose's #sorted:. #sortedAs operates on boolean as well. Any opinion?

Mondrian + Glamour = inconsistent background color

by Johan Fabry

Hi all, Using todays moose and pharo rc2. See the image below to understand what the title means. I'd like the entire mondrian pane to be white, as it was in previous versions. How do I do this?
