Re: [Pharo-users] About patterns, UML and documentation

I think the key to this is intention revealing names and comments. And shipping unit tests that are the best example of "running documentation". Take Sven's NeoCSV package as an example. Great documentation and very good method names. and a complete set of tests. Sounds frightening at first

Hi Marc. In Smalltalk, we rely on naming conventions a lot. The great thing is that Smalltalk selectors/symbols/method names read like English. aDictionary at: aKey put: anObject. aString indexOf: aCharacter startingAt: start ifAbsent: aBlock Seems pretty clear, no? We also rely on

Re: [Pharo-users] How to migrate an object to a subclass of its class but with new inst vars ?

So, I do not think that is possible… Any solution I see is either to change the superclass or to add an external object with a mapping between your new objects and the values of your new IVs. Or you do the migration and after you add the IV once all instances are migrated. But, I repeat that,
