AspectMaps website
by Johan Fabry 19 Apr '10

19 Apr '10

Hi all, I have the AspectMaps website in a more or less presentable state. Maybe it would be worthwhile linking to it from the tools page on moosetechnology.org The URL is http://pleiad.cl/aspectmaps The screencast is very basic right now, I hope to find some time soon to make it more fancy, showing more features and adding voice to explain what is going on. In any case, comments are always welcome! -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

Moose 4.0?
by Alexandre Bergel 13 Apr '10

13 Apr '10

Hi! Where are we with the release? I checked the remaining issues and closed the one that were fixed or that I cannot reproduce. I am not expert in Glamour or the lazy group definition, but I would like to see Moose 4.0 out. How can I help? We can do some remote pair programming. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Re: Current model and properties

Hi Gabi, Ahh, now I understand. Any entity answers to mooseModel, so you can do: FAMIXClass>>someMethod self mooseModel ... Great that you are using the Pharo version. Just for convenience, you can find the latest development image here: http://hudson.moosetechnology.org/job/moose-latest-dev/lastSuccessfulBuild/… Please let us know if you have further problems.

Current model and properties
by Gabriela Arevalo 12 Apr '10

12 Apr '10

Hi guys, I have two basic questions regarding the implementation of Moose 1) How do we manage now the currentModel (the selected Model in the Moose UI)? A long time ago :) :), we have had the ModelManager class and we could do ModelManager uniqueInstance currentModel 2) Properties: I have seen that we are using pragmas from the instance side. Is it right? Or are there any other way of specifying them? Cheers, Gabi

Hi Steph, This mail from Joachim Geidel might help with tweaking the memory in VW.

Hi all I'm doing some experiences with fingerprint and I want to load Squeak38 mse in Moose on VW7.6 However I get some problems (memory not sufficient). Does one of you know how I can change the initial memory of VW? Stef

cycles
by Tudor Girba 09 Apr '10

09 Apr '10

Hi, Jannik (and Simon?) is doing a great job in removing cycles in Moose. This means that methods get moved around between packages. Thus, if you update packages one by one in the wrong order, you might get to miss some methods. Best is to take a fresh image. Cheers, Doru -- www.tudorgirba.com "Reasonable is what we are accustomed with."

moose jee and opax

Hi Fabrizio, I noticed that some classes related to XML parsing that should belong to MooseJEE were in Opax. I now moved them to MooseJEE. Cheers, Doru -- www.tudorgirba.com "Yesterday is a fact. Tomorrow is a possibility. Today is a challenge."
