Mojo::D...Methods(3)

💖 NAME 💖

Okay so this is the Mojo::D...Methods(3) page from User Contributed Perl Documentation, and the main character is Mojo::DynamicMethods — Fast dynamic method dispatch. ✨

✨ SYNOPSIS ✨

package MyClass;
use Mojo::Base -base, -signatures;

use Mojo::DynamicMethods -dispatch;

sub BUILD_DYNAMIC ($class, $method, $dyn_methods) {
  return sub {...};
}

sub add_helper ($self, $name, $cb) {
  Mojo::DynamicMethods::register 'MyClass', $self, $name, $cb;
}

package main;

# Generate methods dynamically (and hide them from "$obj->can(...)")
my $obj = MyClass->new;
$obj->add_helper(foo => sub { warn 'Hello Helper!' });
$obj->foo;

🌸 DESCRIPTION 🌸

Mojo::DynamicMethods provides dynamic method dispatch for per-object helper methods without requiring use of AUTOLOAD. It’s giving helper magic, but make it fast. 💅

To opt your class into dynamic dispatch, simply pass the -dispatch flag:

use Mojo::DynamicMethods -dispatch;

Then implement a BUILD_DYNAMIC method in your class, and make sure that the key you use to lookup methods in $dyn_methods is the same thing you pass as $ref to register.

sub BUILD_DYNAMIC ($class, $method, $dyn_methods) {
  return sub ($self, @args) {
    my $dynamic = $dyn_methods->{$self}{$method};
    return $self->$dynamic(@args) if $dynamic;
    my $package = ref $self;
    croak qq{Can't locate object method "$method" via package "$package"};
  };
}

⚠️ Note that this module will summon Cthulhu, use it at your own risk! 🐙

🛠️ FUNCTIONS 🛠️

Mojo::DynamicMethods implements the following functions.

🎀 register 🎀

Mojo::DynamicMethods::register $class, $ref, $name, $cb;

Registers the method $name as eligible for dynamic dispatch for $class, and sets $cb to be looked up for $name by reference $ref in a dynamic method constructed by BUILD_DYNAMIC. That’s the whole function, bestie. 🫶
