NAME

       Cz::Sort - Czech sort

SYNOPSIS

               use Cz::Sort;
               my $result = czcmp("_x j&a", "_&p");
               my @sorted = czsort qw(plachta plaoka Planieka planieka plani);
               print "@sorted\n";

DESCRIPTION

       Implements czech sorting conventions, indepentent on current locales in effect, which are
       often bad. Does the four-pass sort. The idea and the base of the conversion table comes
       from Petr Olsak's program csr and the code is as compliant with CSN 97 6030 as possible.

       The basic function provided by this module, is czcmp. If compares two scalars and returns
       the (-1, 0, 1) result. The function can be called directly, like

               my $result = czcmp("_x j&a", "_&p");

       But for convenience and also because of compatibility with older versions, there is a
       function czsort. It works on list of strings and returns that list, hmm, sorted. The
       function is defined simply like

               sub czsort
                       { sort { czcmp($a, $b); } @_; }

       standard use of user's function in sort. Hashes would be simply sorted

               @sorted = sort { czcmp($hash{$a}, $hash{$b}) }
                                                       keys %hash;

       Both czcmp and czsort are exported into caller's namespace by default, as well as cscmp
       and cssort that are just aliases.

       This module comes with encoding table prepared for ISO-8859-2 (Latin-2) encoding. If your
       data come in different one, you might want to check the module Cstocs which can be used
       for reencoding of the list's data prior to calling czsort, or reencode this module to fit
       your needs.
