SYNOPSIS

use feature 'say';
use Package::Prototype;

my $obj = Package::Prototype->bless({
        foo => 10,
        bar => "Hello",
        baz => sub {
            my ($self, $arg) = @_;
            say "$arg, World";
        },
        # It do not create a method if key is started at '_'
        _data => "internal data"
    });

say "\$obj classname: " . ref $obj;
say Dumper $obj;
say $obj->foo;        # 10
say $obj->bar;        # "Hello"
$obj->baz($obj->bar); # "Hello, World"

my $obj2 = Package::Prototype->bless({
        hoge => [1..10],
        fuga => {abc => "def"}
    }, 'CLASS');

say "\$obj2 classname: " . ref $obj2;

# reference
my $a = $obj2->hoge;
my $h = $obj2->fuga;

# wantarray
my @a = $obj2->hoge;
my %h = $obj2->fuga;

$obj2->prototype(bow => sub { say "Bow!!" }, nyao => sub { say "Nyao!!" });
$obj2->prototype(baw => 10, nyan => "nyan");
$obj2->nyao(); # "Nyao!!"
$obj2->bow();  # "Bow!!"
say "bow: " . $obj2->baw . " nyan: " . $obj2->nyan;

DESCRIPTION

Package::Prototype can create prototype object like javascript.

This module can provide anonymous packages which are independent of the main namespace if not specified by classname. Also, available as an object instance.

METHODS

bless($ref :HashRef[, $classname :Str])

Create a new anonymous package and an instance. The optional $clasname argument sets the stash's name. $classname default is __ANON__.

That instance also provide a method that will return values corresponding to keys that do not start with '_'.

my $obj = Package::Prototype->bless({
    foo => 10,
    bar => sub { say $_[1] },

    # It do not create a method if key is started at '_'
    _data => "internal data"
});

say $obj->foo; # 10
say $obj->bar("Hello");

# $obj->_data is not provided

prototype($key :Str => $val :Any, ...)

This method can be used from the generated instance. By using this, it is possible to add new methods easily.

$obj->prototype(add => sub {
    my $self = shift;
    return $_[0] + $_[1];
});

$obj->add(3, 5); # 8
