NAME

Sort::Sub::by_rand - Sort randomly using Perl's rand()

VERSION

This document describes version 0.120 of Sort::Sub::by_rand (from Perl distribution Sort-Sub), released on 2020-05-25.

SYNOPSIS

Generate sorter (accessed as variable) via Sort::Sub import:

 use Sort::Sub '$by_rand'; # use '$by_rand<i>' for case-insensitive sorting, '$by_rand<r>' for reverse sorting
 my @sorted = sort $by_rand ('item', ...);

Generate sorter (accessed as subroutine):

 use Sort::Sub 'by_rand<ir>';
 my @sorted = sort {by_rand} ('item', ...);

Generate directly without Sort::Sub:

 use Sort::Sub::by_rand;
 my $sorter = Sort::Sub::by_rand::gen_sorter(
     ci => 1,      # default 0, set 1 to sort case-insensitively
     reverse => 1, # default 0, set 1 to sort in reverse order
 );
 my @sorted = sort $sorter ('item', ...);

Use in shell/CLI with sortsub (from App::sortsub):

 % some-cmd | sortsub by_rand
 % some-cmd | sortsub by_rand --ignore-case -r

DESCRIPTION

This is equivalent to:

 sub { int(3*rand())-1 }

The case sensitivity ("i") and reverse ("r") flags are not relevant.
