Re: How do I sort a Hash of Hashes?

⭐ in reply to How do I sort a Hash of Hashes?

You have to rewrite the code so, that it sorts using the string comparitor (cmp) and you have to dereference the Hash of Hashes with an arrow operator.

sort { $products{$a}->{"name"} cmp $products{$b}->{"name"} }

You have to rewrite the code so, that it sorts using the string comparitor (cmp) and you have to dereference the Hash of Hashes with an arrow operator. The extra arrow isn't needed anymore. This changed sometime at or before 5.6.1.	[reply]
