Re: sorting not sort

[Roger]

You can put multiple conditions in the sort, using the || operator, so that when the first rule is equal (ie, =0), the second rule will kick in, otherwise take the first rule.

$strings{"E1,E2"} = 1;
$strings{"E1,E3"} = 3;
$strings{"E1,E4"} = 2;
$strings{"E1,E5"} = 3;
$strings{"E1,E6"} = 3;
$strings{"E1,E7"} = 5;
$strings{"E1,E8"} = 1;
$strings{"E1,E9"} = 0;
$strings{"E1,E10"} = 12;


my @sorted =
    map { $_->[0] }
    sort { ($b->[2] <=> $a->[2]) || ($a->[1] <=> $b->[1]) }
    map {
        my $old_key = $_;

        # transform my keys so I can compare them as digits
        my ($k1, $k2) = $old_key =~ /(\d)/g;
        my $new_key = sprintf("%04d%04d", $k1, $k2);

        [ $old_key, $new_key, $strings{$old_key} ]
    } keys %strings;

print map{ "$_ = $strings{$_}\n" } @sorted;
