working with dates
by Kel Graham 12 Dec '06

12 Dec '06

Hello, I'd like to see how to control the formatting and storage of dates. I'm in the UK so would like to store my dates in yyyy-mm-dd format, but display them as dd-mm-yyyy; or as '12 December 2006' sometimes as well. I've looked at the Date class, but apart from the printFormat: method (which I can't see an explanation of the format) I can't see any easy way of ensuring that squeak converts my dd-mm-yyyy input into a nice ISO yyyy-mm-dd format. Could anyone suggest some classes/code to look at? Thanks very much, Kel.

Adding instance variables during runtime
by Warakorn Paphrawat 12 Dec '06

12 Dec '06

In my current little project I would like write classes in Smalltalk. However, when I am designing the classes I do not know, which instance variables the class should have. While I am running the application, the user (or another agent) determines which instance variables should be assigned to a class. How can I add instance variables and possibly class variables to a class, while the program is running ? Actually how can the Smalltalk code be automatically transformed (and "accepted") from the 'BEFORE' state to the 'AFTER' state. // BEFORE // Object subclass: #Class1 instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'some-category' // AFTER // Object subclass: #Class1 instanceVariableNames: 'InstVar1 InstVar2 ' classVariableNames: 'ClassVar1 ClassVar2' poolDictionaries: '' category: 'some-category' I worked with the ClassBuilder class, but I haven't achieved this kind of automated code transformation. Let's assume the desired variable names are available as normal strings and should be added one after another (method like: addNewInstanceVariable: aString ). Don't worry about getter/setter methods for the new instance variables, that's another issue. Thanks in advance Warakorn --------------------------------- Want to start your own business?
