NAME
Pudu - A light-weight Moose-like object system that makes it easy to create encapsulated, immutable objects
SYNOPSIS
package Animal {
use Pudu;
has name => ( is => 'rw' );
method speak => sub {
"grunt"
};
private {
method hide => sub {
"this is my hiding place"
};
};
protected {
method share => sub {
"I share with my friends"
};
};
}
package Cat {
use Pudu;
is 'Animal';
method speak => sub {
"meow"
};
method reveal => sub {
self->share . " and strangers";
};
method betray => sub {
self->hide
};
}
$a = Animal->new(name => 'Bruce');
$a->speak # => "grunt"
$a->hide # dies
$a->share # dies
$c = Cat->new(name => 'Selina');
$c->speak # => "meow"
$c->reveal # => "I share with my friends and strangers"
$c->betray # dies
FUNCTIONS
UTILITIES
- clean
Removes all keywords from from the given namespace.
It's used internally by Pudu::Object.
Example:
package Cat {
use Pudu;
has name => ( is => 'rw' );
method speak => sub {
"meow"
};
}
my $c = Cat->new(name => "Selina");
$c->name; # => "Selina"
$c->speak; # => "meow"
$c->has; # dies
$c->method; # dies
KEYWORDS
The following functions are all exported by default when using
the Pudu module, and are designed to provide some
syntactic sugar for the inner workings.
- has
Keyword for defining attributes
Example:
package Point {
use Pudu;
has x => ( is => 'rw' );
has y => ( is => 'rw' );
}
- self
Keyword for recursively refering to the current object
Example:
package Cat {
use Pudu;
has name => ( is => 'ro' );
method speak => sub {
"Meow... my name is " . self->name;
};
}
- is
Keyword for establishing an 'is a' relationship between a child class and it's parents.
Example:
package Point3D {
use Pudu;
is 'Point';
}
- does
Keyword for establishing a 'does' relationship between a class and a Role.
NOTE: this does not work yet
Example:
package LazyList {
use Pudu;
does 'Enumerable';
}
- private
Keyword for designating a private scope
Example:
package Cat {
use Pudu;
private {
method hide => sub {
"hidden"
};
};
}
Cat->new->hide; # dies
- protected
Keyword for designating a protected scope
Example:
package Animal {
use Pudu;
protected {
method share => sub {
"I share with my friends"
};
};
}
package Cat {
use Pudu;
is 'Animal';
method reveal => sub {
self->share . " and with strangers"
};
}
Animal->new->share; # dies
Cat->new->reveal; # => "I share with my friends and with strangers"
- method
Keyword for defining a method
Example:
package Dog {
use Pudu;
method speak => sub {
"bark"
};
}
