Hi Monks,
I'm trying to replace a Hash-Ref with an Array-Ref. Here's a simplified code-snippet for your understanding:
use Data::Dumper;
my $ref = { "baz" => [1,2,3,4] };
print Dumper $ref;
foo($ref);
#$ref should be [1,2,3,4] now
print Dumper $ref;
sub foo {
my $bar = shift;
$bar = $bar->{baz}; #(1)
#@$bar = @{$bar->{baz}}; #(2)
print Dumper $bar;
}
I want that at the end $ref contains a reference to $ref->{baz}. This has to be done in a sub. My first try was (1), but it failed because it only changes $bar. My second try would have been (2), but this fails because $bar (and $ref) is an Hash-Ref.
Is there a way to accomplish this at all?
Thanks for you help, Markus

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
