Another slight variation on a custom sort sub:
c:\@Work\Perl\monks>perl -le
"use warnings;
use strict;
;;
use Test::More 'no_plan';
use Test::NoWarnings;
;;
my $OptOrd = 1;
;;
my $Test = [
[ 1, 'c' ],
[ 2, 'a' ],
[ 3, '' ],
[ 4, undef ],
[ 5, 'foo' ],
[ 6, '' ],
[ 7, 'cee' ],
[ 8, undef ],
[ 9, 'tee' ],
[ 10, 't' ],
];
;;
my $Expected = [
[ 3, '' ],
[ 6, '' ],
[ 2, 'a' ],
[ 1, 'c' ],
[ 7, 'cee' ],
[ 5, 'foo' ],
[ 10, 't' ],
[ 9, 'tee' ],
[ 4, undef ],
[ 8, undef ],
];
;;
my @got = sort by_deaccented_ascending_with_undef_highest @$Test;
;;
is_deeply \@got, $Expected, 'custom sort sub';
;;
done_testing;
;;
sub deaccent { return $_[0]; }
;;
sub by_deaccented_ascending_with_undef_highest {
my ($aa, $bb) = ($a->[$OptOrd], $b->[$OptOrd]);
;;
return defined $aa && defined $bb
? deaccent($aa) cmp deaccent($bb)
: defined $bb cmp defined $aa
;
}
"
ok 1 - custom sort sub
1..1
ok 2 - no warnings
1..2
defined returns
'' (empty string) for undefined,
1 for defined, and
'' will lexically
cmp below
1.
