I'd vote to add them, only if we , in exchange, find the other two(or more) methods to remove. A class protocol is heavily bloated, and adding even more on top of that, even if its userful, could be lost in a jungle of many others. > Stef > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] String to Number conversion

by Guillermo Polito

If you do: Number readFrom: '3foo'. --> exception Number readFrom: '3foo' readStream --> 3 String#asNumber is defined as ^Number readFromString: self And #readFromString: does the readStream. They are two different things. What Integer>>readFrom: does and what String>>asNumber does. String>>asNumber should fail :).

[Pharo-project] Why TextConstants is not defined in a SharedPool classVar?

by StÃ©phane Ducasse

Hi I should say that I liked the introduction of SharedPool made by andreas long time ago to replace PoolDictionaries. Now I was wondering why TextContants is not defined as a classVariable of a subclass of SharedPool like all the other PoolDictionaries? Stef

Now we should identify user of readFrom: that in fact are expecting squeezeOutNumber and fix them. Well, it seems that the current readFrom: only requires the string to _start_ with a valid format. This means that: '3foo' asInteger = 3 Should we not fail here too? What are the opinions? Johan

[Pharo-project] SystemNavigation code rewrite?

by StÃ©phane Ducasse

Hi I looked at the code of SystemNavigation and I think that this is the time to rewrite it :) I know I assemble the code from Browser and SystemDictionary at that time and we can see it. I would like also to have allClassesUsingPool: allClassesUsingPoolVariable: http://code.google.com/p/pharo/issues/detail?id=2868 In addition I would like to be able to specify the environment in which the navigation is done so that we could navigate multiple environments like the ones for bootstrapping the system we are fighting with :) http://code.google.com/p/pharo/issues/detail?id=2869 Stef
