( #3333=superdoc: print w/replies, xml ) Need Help??

[ I had this written before an internet outage. I might as well still post it even though something similar was already posted. ]

First, the solution is to set Purity

#!/usr/bin/perl use strict; use Data::Dumper; my $var1 = { temp => "123" }; my $hash_ref; push @{$hash_ref->{test1}}, $var1; push @{$hash_ref->{test2}}, $var1; print Dumper($hash_ref); my $dump = do { local $Data::Dumper::Purity = 1; Dumper($hash_ref); }; my $VAR1; eval "$dump; 1" or die $@; print Dumper($VAR1);
$VAR1 = { 'test1' => [ { 'temp' => '123' } ], 'test2' => [ $VAR1->{'test1'}[0] ] }; $VAR1 = { 'test1' => [ { 'temp' => '123' } ], 'test2' => [ $VAR1->{'test1'}[0] ] };

But really, Data::Dumper is not the right tool. Storable can best represent Perl data structures. If you want something human-readable, both JSON and YAML cover all the basics.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
