I don't exactly know how should I use Data::Dumper
Best to have a quick look at the Data::Dumper documentation. The Dumper() function is exported by default and gives a pretty crude picture of the data. Give it an array and it will treat each element as a separate variable but give it a reference to the array and you see an anonymous array. Dump() and its faster but not always available sibling Dumpxs() are fiddlier but more useful as they can give a more accurate picture.
Here's a brief example.
johngg@shiraz ~ $ perl -Mstrict -Mwarnings -MData::Dumper -E ' my @atts = qw{ att1 att2 att3 }; say Dumper( @atts ); say Dumper( \ @atts ); say Data::Dumper->Dump( [ \ @atts ], [ qw{ *atts } ] ); say Data::Dumper->Dumpxs( [ \ @atts ], [ qw{ *atts } ] );' $VAR1 = 'att1'; $VAR2 = 'att2'; $VAR3 = 'att3'; $VAR1 = [ 'att1', 'att2', 'att3' ]; @atts = ( 'att1', 'att2', 'att3' ); @atts = ( 'att1', 'att2', 'att3' );
I hope this is helpful.
Cheers,
JohnGG
