NAME

MooseX::Role::Pluggable - add plugins to your Moose classes

VERSION

version 0.07

SYNOPSIS

    package MyMoose;
    use Moose;
    with 'MooseX::Role::Pluggable';

    my $moose = MyMoose->new({
      plugins => [ 'Antlers' , 'Tail' , '+After::Market::GroundEffectsPackage' ] ,
      # other args here
    });

    or, if you need to pass arguments to a plugin module, you can do that by
    using a hashref in the plugin list:

    my $moose = MyMoose->new({
      plugins  => [
        { 'Antlers' => { long  => 1, } },
        { 'Tail'    => { short => 1, } },
        '+After::Market::GroundEffectsPackage' => {},
      ]
    });

    foreach my $plugin ( @{ $moose->plugin_list } ) {
      if ( $plugin->can( 'some_method' )) {
        $plugin->some_method();
      }
    }

    # call a method in a particular plugin directly
    # (plugin_hash() returns a hash ref of 'plugin_name => plugin')
    $moose->plugin_hash->{Antlers}->gore( $other_moose );

    # plugins are indexed by the name that was used in the original 'plugins' list
    $moose->plugin_hash->{After::Market::GroundEffectsPackage}->light_up();

    # see the documentation for MooseX::Role::Pluggable::Plugin for info on
    # how to write plugins...

DESCRIPTION

This is a role that allows your class to consume an arbitrary set of plugin modules and then access those plugins and use them to do stuff.

Plugins are loaded based on the list of plugin names in the 'plugins' attribute. Names that start with a '+' are used as the full name to load; names that don't start with a leading '+' are assumed to be in a 'Plugins' namespace under your class name. (E.g., if your app is 'MyApp', plugins will be loaded from 'MyApp::Plugin').

NOTE: Plugins are lazily loaded -- that is, no plugins will be loaded until either the 'plugin_list' or 'plugin_hash' methods are called. If you want to force plugins to load at object instantiation time, your best bet is to call one of those method right after you call 'new()'.

Plugin classes should consume the 'MooseX::Role::Pluggable::Plugin' role; see the documentation for that module for more information.

NAME

MooseX::Role::Pluggable - add plugins to your Moose classes

METHODS

plugin_hash

Returns a hashref with a mapping of 'plugin_name' to the actual plugin object.

plugin_list

Returns an arrayref of loaded plugin objects. The arrayref will have the same order as the plugins array ref passed in during object creation.

plugin_run_method( $method_name )

Looks for a method named $method_name in each plugin in the plugin list. If a method of given name is found, it will be run. (N.b., this is essentially the foreach loop from the "SYNOPSIS".)
