Sort::Sub::by_perl_function(3) User Contributed Perl Documentation Sort::Sub::by_perl_function(3)

Sort::Sub::by_perl_function - Sort by Perl function

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

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

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

Generate sorter (accessed as subroutine):

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

Generate directly without Sort::Sub:

 use Sort::Sub::by_perl_function;
 my $sorter = Sort::Sub::by_perl_function::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_perl_function
 % some-cmd | sortsub by_perl_function --ignore-case -r

This:

 use Sort::Sub '$by_perl_function', {function=>'length'};
 my @sorted = sort $by_perl_function @data;

is equivalent to:

 my @sorted = sort { length($a) <=> length($b) } @data;

"*" marks required arguments.

perl::funcname.

bool.

Compare using Perl's <=> instead of cmp.
