-whereas
-
- my $dd = Dumper;
-
-is equivalent to:
-
- my $dd = Data::Dumper->new([])
- ->Terse(1)
- ->Indent(1)
- ->Useqq(1)
- ->Deparse(1)
- ->Quotekeys(0)
- ->Sortkeys(1);
-
So for the structure:
{ foo => "bar\nbaz", quux => sub { "fleem" } };
use warnings;
use strict 'refs';
'fleem';
- }
+ },
}
instead of the default Data::Dumper output:
$VAR1 = {
- 'quux' => sub { "DUMMY" },
- 'foo' => 'bar
+ 'quux' => sub { "DUMMY" },
+ 'foo' => 'bar
baz'
};
(note the tab indentation, oh joy ...)
-=head1 DESCRIPTION
+(The trailing comma on the last element of an array or hash is enabled by a new
+feature in Data::Dumper version 2.159, which was first released in Perl 5.24.
+Using Data::Dumper::Concise with an older version of Data::Dumper will still
+work, but you won't get those commas.)
-This module always exports a single function, Dumper, which can be called
-with an array of values to dump those values or with no arguments to
-return the Data::Dumper object it's created. Note that this means that
+If you need to get the underlying L<Dumper> object just call C<DumperObject>.
+
+Also try out C<DumperF> which takes a C<CodeRef> as the first argument to
+format the output. For example:
+
+ use Data::Dumper::Concise;
+
+ warn DumperF { "result: $_[0] result2: $_[1]" } $foo, $bar;
- Dumper @list
+Which is the same as:
-will probably not do what you wanted when @list is empty. In this case use
+ warn 'result: ' . Dumper($foo) . ' result2: ' . Dumper($bar);
- Dumper \@list

-instead.
+This module always exports a single function, Dumper, which can be called
+with an array of values to dump those values.
It exists, fundamentally, as a convenient way to reproduce a set of Dumper
options that we've found ourselves using across large numbers of applications,
