Perl6::Perl - $obj->perl just like $obj.perl in Perl 6
# As UNIVERSAL method use Perl6::Perl; use Foo::Bar; my $baz = Foo::Bar->new(); my $bazz = eval( $baz->perl ); # $bazz is a copy of $baz # As subroutine so you can apply to non-objects use Perl6::Perl qw/perl/; # explicitly import perl $scalar; perl \@array; perl \%hash; perl \*GLOB; perl sub{ $_[0] + 1 }; # Ruby's p p $complex_object;
In Perl 6, everything is an object and every object comes with the .perl method that returns the eval()uable representation thereof. This module does just that.
.perl
eval()
Since Perl 5 is already shipped with Data::Dumper, this module makes use of it; In fact $obj->perl is just a wrapper to Dumper($obj) with options slightly different from Data::Dumper's default.
$obj->perl
Dumper($obj)
This module also comes with p, which is analogous to that of ruby; It is simply sub p{ print perl(@_), "\n" }. But you save a lot of key strokes -- even more concise than say @_.perl .
p
sub p{ print perl(@_), "\n" }
say @_.perl
Though p is not Perl6's spec, I couldn't resist adding this to this module because so many people envy Ruby for it :).
Perl6::Perl uses the following values as default:
1 so you can serialize coderef.
1 so no $VAR1 = appears.
$VAR1 =
1 so you can safely inspect binary data as well as Unicode characters.
2 if the object is a coderef, 0 otherwise.
You can override these by feeding Data::Dumper options as follows;
$obj->perl(purity => 1); # if the object contains circular reference.
Note you can use all lowercaps here.
None by default. perl and p are exported on demand.
