套件： libdata-sorting-perl (0.9-4)

Perl module for multi-key sort using function results

Data::Sorting provides functions to sort the contents of arrays based on a collection of extraction and comparison rules. Extraction rules are used to identify the attributes of array elements on which the ordering is based; comparison rules specify how those values should be ordered.

Index strings may be used to retrieve values from array elements, or function references may be passed in to call on each element. Comparison rules are provided for numeric, bytewise, and case-insensitive orders, as well as a 'natural' comparison that places numbers first, in numeric order, followed by the remaining items in case-insensitive textual order.
