Have you read: ?
perldoc Data::Dumper
Maybe this is what you need:
* $Data::Dumper::Indent *or* *$OBJ*->Indent(*[NEWVAL]*)
Controls the style of indentation. It can be set to 0, 1, 2 or 3.
Style 0 spews output without any newlines, indentation, or spaces
between list items. It is the most compact format possible that can
still be called valid perl. Style 1 outputs a readable form with
newlines but no fancy indentation (each level in the structure is
simply indented by a fixed amount of whitespace). Style 2 (the
default) outputs a very readable form which takes into account the
length of hash keys (so the hash value lines up). Style 3 is like
style 2, but also annotates the elements of arrays with their index
(but the comment is on its own line, so array output consumes twice
the number of lines). Style 2 is the default.
