Hi list,
How do I find all classes belonging to a category? I could go through the Smalltalk dictionary, but I'm sure there is a better way, :-)
Everything related to Categories is strange. (this is code from the 70ties... it violates the "principle of the least surprise" as often as possible by being done exactly as you would not do it if you would implement it... SystemOrganization listAtCategoryNamed: 'Files-System' SystemOrganization here is a global pointing ot one instance of SystemOrganizer. This, of course, returns not the classes (this would be too easy), bit symbols equal to the class names (suitable to query Smalltalk globals): (SystemOrganization listAtCategoryNamed: 'Files-System') collect: [:each | Smalltalk globals at: each] -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.
