Re^2: RFC: Sorting IPv4 addresses

[bv]

The packing and XS things are good points. My intended audience was the more casual user who would be uncomfortable implementing anything in XS (I'm only just barely dabbling in Inline::C, myself).

As for split without unpack, I thought that was covered in the splitwise case, which I unabashedly stole from Understanding transformation sorts (ST, GRT), the details. Did you mean something else?

No, that one doesn't pack

Ah, I see. That was another case of grabbing code from another node without checking enough. This code runs (by my benchmark) 33% faster than the old split_int:

#...
split_pack => sub {
            my @sorted = map { join '.', unpack("CCCC", $_) }
                sort { $a cmp $b }
                map { pack("CCCC",split /\./) } @ips;
        },
#...
