SortFunctions

SortFunctions is a set of utility classes and methods extensions that enable you to build composite sorting criteria without having to deal with complex block nesting and logic.

It enables you to write stuff like:

people sorted: #lastName ascending, #firstName descending.

SortFunctions is an version of the original TAG-SortFunctions written by Travis Griggs for VisualWorks and then ported to Pharo/Squeak by Nicolas Cellier.

Maggrite Support

This version of SortFunctions enables you to use Magritte Descriptions as building blocks of your sorting criteria.

E.g.

customers sorted: nameDescription ascending, representativeDescription descending undefinedLast

The above code snippet will sort the customers collection first by nameDescription and then by *representativeDescription * leaving those without an assigned sales representative at the end.
