Get cloud.uuid optionvalue from extra config without iterating through the array?

MR-Z — Thu, 26 Sep 2013 23:17:06 GMT

I need to get the cloud.uuid (or any other optionValue for that matter) from the extraConfig data object. Is there a way to get to the value of a specific key without having to iterating through the array? As this is not a hash, attempt at getting to the value with this fails miserably:

$extra->{'could.uuid'}...

Here is an iteration approach that works.

my $extra = $vm->config->extraConfig;

foreach (@$extra) {

print $_->value if ($_->key =~ /cloud.uuid/);

}

Thanks!

Unfortunately it's an array, so you'll have to iterate. If you wanted to, you could convert it to a hash.

You could use 'grep' as well to get a one liner. It won't be such a large array in any event that there is any real dramatic speed increase between a hash and an array.

Thanks stumpr. Understood. Just wanted to see if anything magic out there...

You can use config.extraConfig["cloud.uuid"] as the property name in PropertySpec pathset and that will retrieve only the cloud.uuid extraconfig.

Within perl you can do the following to find an element in an array:

if (grep {$_ eq $element} @TheArray) { print "Element '$element' found!\n" ; }

(Original article here How to find out if X is an element in an array? )

You can adapt this to your scenario by doing:

print $_->value if (grep {$_->key =~ /cloud.uuid/} @$extra);
