hello Monks,

maybe I can give my answer ?!? fantastic !! I was warking on dumping HoH on the screen for a better overview and I wrote this:

my %h2=(
'AAA' => 'aaa',
'BBB' => 'bbb',
'CCC' => {'A1' => a1,
          'B1' => 'b1',
          'C1' => {'A2' => a2,'B2' => 'b2','C2' => 'c2END'}},
'DDD' => 'ddd',
);


my $ref2 = \%h2;

&ddump($ref2);

sub ddump
{
  my $ref  = shift;
  my $deep = shift||1;
  foreach my $k (sort keys %{$ref})
          {
            if (ref( ${$ref}{$k}))  {print "\t" x $deep."$k =>\n"; 
             &ddump (${$ref}{$k}, ($deep+1))
            }
            else {print "\t" x ($deep)."$k => ${$ref}{$k}\n";}
            $deep-1;
          }
}

Then I found a column by Merlyn, only 8 year later, that suggested me a new rebus to solve: how about to dump via CGI.pm table ?? or to be precise Hohoh->TableOfTableOfTable here the code:

use warnings;
use CGI qw /:all -nph/; #on Win32
 $|++;
 $POST_MAX=100;
 $DISABLE_UPLOAD=1;
 print header();
print start_html();
my %HoHoH = ();#feed your hoh here
my $ref2 = \%HoHoH ;

print &table_center(&complextable($ref2));

print end_html;

sub td_center{{-align=>center} td([@_]); }#separated for customization

sub tr_center {{-align=>center}Tr([@_]); }

sub table_center { 
                  table({-title=>'oOOOo',
                  -bgcolor=>"#000000",
                  -border=>1,
                  -bordercolor=>"red", 
                  -cellspacing=>"0",
                  -width=>"80%", 
                  -cellpadding=>"0"},
                   @_); 
                  }

sub complextable
{
  my $ref  = shift;
  my @righe;
  foreach my $k (sort keys %{$ref})
  {
  if (ref( $$ref{$k} ))
   {
    push @righe,
    (&tr_center
       (&td_center
        ($k,(&table_center
          (&complextable($$ref{$k})) 
         )
        )
       )
     ) ;
  }
  else
     {
      push @righe, (&tr_center(&td_center($k, $$ref{$k} )));
     }
    }
  return @righe;
}

Hope this help. Hope some golf master to squize my homegrown code.

• 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.
