NAME

       Data::Dumper::Concise::Sugar - return Dwarn @return_value

SYNOPSIS

         use Data::Dumper::Concise::Sugar;

         return Dwarn some_call(...)

       is equivalent to:

         use Data::Dumper::Concise;

         if (wantarray) {
            my @return = some_call(...);
            warn Dumper(@return);
            return @return;
         } else {
            my $return = some_call(...);
            warn Dumper($return);
            return $return;
         }

       but shorter. If you need to force scalar context on the value,

         use Data::Dumper::Concise::Sugar;

         return DwarnS some_call(...)

       is equivalent to:

         use Data::Dumper::Concise;

         my $return = some_call(...);
         warn Dumper($return);
         return $return;

       If you need to force list context on the value,

         use Data::Dumper::Concise::Sugar;

         return DwarnL some_call(...)

       is equivalent to:

         use Data::Dumper::Concise;

         my @return = some_call(...);
         warn Dumper(@return);
         return @return;

       If you want to label your output, try DwarnN

         use Data::Dumper::Concise::Sugar;

         return DwarnN $foo

       is equivalent to:

         use Data::Dumper::Concise;

         my @return = some_call(...);
         warn '$foo => ' . Dumper(@return);
         return @return;

       If you want to output a reference returned by a method easily, try $Dwarn

        $foo->bar->{baz}->$Dwarn

       is equivalent to:

         my $return = $foo->bar->{baz};
         warn Dumper($return);
         return $return;

       If you want to format the output of your data structures, try DwarnF

        my ($a, $c) = DwarnF { "awesome: $_[0] not awesome: $_[1]" } $awesome, $cheesy;

       is equivalent to:

         my @return = ($awesome, $cheesy);
         warn DumperF { "awesome: $_[0] not awesome: $_[1]" } $awesome, $cheesy;
         return @return;

       If you want to immediately die after outputting the data structure, every Dwarn subroutine
       has a paired Ddie version, so just replace the warn with die.  For example:

        DdieL 'foo', { bar => 'baz' };

DESCRIPTION

         use Data::Dumper::Concise::Sugar;

       will import Dwarn, $Dwarn, DwarnL, DwarnN, and DwarnS into your namespace. Using Exporter,
       so see its docs for ways to make it do something else.

   Dwarn
         sub Dwarn { return DwarnL(@_) if wantarray; DwarnS($_[0]) }

   $Dwarn
         $Dwarn = \&Dwarn

   $DwarnN
         $DwarnN = \&DwarnN

   DwarnL
         sub Dwarn { warn Data::Dumper::Concise::Dumper @_; @_ }

   DwarnS
         sub DwarnS ($) { warn Data::Dumper::Concise::Dumper $_[0]; $_[0] }

   DwarnN
         sub DwarnN { warn '$argname => ' . Data::Dumper::Concise::Dumper $_[0]; $_[0] }

       Note: this requires Devel::ArgNames to be installed.

   DwarnF
         sub DwarnF (&@) { my $c = shift; warn &Data::Dumper::Concise::DumperF($c, @_); @_ }

TIPS AND TRICKS

   global usage
       Instead of always just doing:

         use Data::Dumper::Concise::Sugar;

         Dwarn ...

       We tend to do:

         perl -MData::Dumper::Concise::Sugar foo.pl

       (and then in the perl code:)

         ::Dwarn ...

       That way, if you leave them in and run without the "use Data::Dumper::Concise::Sugar" the
       program will fail to compile and you are less likely to check it in by accident.
       Furthmore it allows that much less friction to add debug messages.

   method chaining
       One trick which is useful when doing method chaining is the following:

         my $foo = Bar->new;
         $foo->bar->baz->Data::Dumper::Concise::Sugar::DwarnS->biff;

       which is the same as:

         my $foo = Bar->new;
         (DwarnS $foo->bar->baz)->biff;

SEE ALSO

       You probably want Devel::Dwarn, it's the shorter name for this module.
