Dumper can be controlled by some attributes, read the man pages first! I, personally, like Data::Dump::Streamer better:

$ perl -e '

use Data::Dump::Streamer;

my $firstname = "Edward";
my $var = 1;
my @jack = ('a', '1', { b => 3, c => [1, 2]});
DumpLex($firstname, $var, \@jack)->Indent(0)->OptSpace(" ")->Out();

'
$firstname = 'Edward';
$var = 1;
@jack = ( 'a', 1, { b => 3, c => [ 1, 2 ] } );

Or, if the vars aren't lexical,

$ perl -e '

use Data::Dump::Streamer;

$firstname = "Edward";
$var = 1;
@jack = ('a', '1', { b => 3, c => [1, 2]});
DumpVars(firstname => $firstname, var => $var, jack => \@jack)->Indent
+(0)->OptSpace(" ")->Out();

'
$firstname = 'Edward';
$var = 1;
$jack = [ 'a', 1, { b => 3, c => [ 1, 2 ] } ];
