IIRC GermÃ¡n told me that the extensions of the package in the repository should be refactors to make in Pharo, and there are things there related to enviroments and system organization.

[Pharo-project] About changes logging

by StÃ©phane Ducasse

Hi I noticed that if I define a method it shows up in the recentMessageSet Now if I load code with mc it does not, even though it is logged in the changes (the logging in the changes is done by SmalltalkImage>>event:) which could indicate that SystemChangeNotifier notified the right tools. Does anybody have an idea? Because this is confusing. Stef

But perhaps sending asString to a Collection of objects should... well, what *should* it return? I think possibly one of the problems in all this is the fallback on printString - that has clearly muddled the waters IMHO. #printString is for the tools, it should give a "readable representation". But #asString is a conversion method - it should give me IMHO the most reasonable conversion for further "use". I agree that #as: etc might be a "better" protocol, but let's say we still want #asString to work for Collections and NOT fall back on #printString - then what should it do? regards, GÃ¶ran

One possibility is that there is an error in the method where the #clone message is being sent, or that the missing method just hasn't been filed in yet.

Stef, As part of his GSoC 2010 project, GermÃ¡n Leiva has been doing some refactoring of this and has some sample code at http://www.squeaksource.com/Environments.html. While it hasn't come as far as I hoped, it does give an interesting insight into some of the relationships between environment, organization, and related things (the Monticello implications were somewhat nontrivial).

could you still have the old one in addition? I think that this is good to have a slow system to find that we are missing basic optimization.
