Slicing hashes

| Perl | 1 Comment

An elegant way to mix and match hash entries is by using the technique of hash slices. For example, let's just say that you have defined the following hash:

my $config = {
  firstname => 'Joseph',
  lastname => 'Smith',
  user => 'pickle',
  database => 'fruits',
  password => 'z4KLf3&3z',
  host => '',

Suppose that you are only interested in the hash-keys related to the database stuff. Then you can use the following fancy one-liner:

my ($dbhost, $dbdatabase, $dbuser, $dbpassword) =
  @$config{ qw( host database user password ) };

As the saying goes, there is always more than one way to do it with Perl. Pretty neat stuff, wouldn't you say?
