After the discussion about multiple sort criteria [1] I decided to make some modifications I was needing, and also repackage the initial port Nicolas Cellier did. The result is the transformation of Nicolas' TAG-SortFunctions [2] "experiment" to a first class project plainly named 'SortFunctions' available at: http://smalltalkhub.com/#!/~emaringolo/SortFunctions/ Nicolas said: "Since I got absolutely zero feedback after a long thread, I assumed it was not interesting anybody... But my personal opinion differs: this should be included in each and every Smalltalk." I sorry for not replying before, I also think this kind of features should be easily discoverable in a default image, and that's why I built a Metacello config to be included, maybe, in the MetaRepo. Credits were preserved in the STHub project site both for Travis and Nicolas. Best regards, Esteban A. Maringolo [1] http://forum.world.st/Has-someone-ever-built-a-sort-block-generator-tp477124... [2] I guess TAG is for Travis A. Griggs
