NAME

       MooseX::App::WritingPlugins - Writing plugins for MooseX::App

SYNOPSIS

        package MooseX::App::Plugin::MyPlugin;

        use Moose::Role;

        sub plugin_metaroles {
            my ($self,$class) = @_;
            return {
                class   => ['MooseX::App::Plugin::MyPlugin::Meta::Class'],
            }
        }

        around 'initialize_command_class' => sub {
           ...
        };

DESCRIPTION

       Plugins are implemented as Moose roles and must reside in the MooseX::App::Plugin::*
       namespace. Metaclasses can be altered via the 'plugin_metaroles' callback method.
       Furthermore Moose method modifiers (around, after, before) can be used to alter the
       behaviour of MooseX::App or its meta classes.

CALLBACKS

   plugin_metaroles
       Optional callback method that should return a hash reference specifying which metaroles
       will be applied to the class metaclass and its contained metaclasses and helper classes.

       Each key should in turn point to an array reference of role names.

       It accepts the following keys:

       •   class

       •   attribute

       •   method

       •   wrapped_method

       •   instance

       •   constructor

       •   destructor

       •   error

METACLASSES

       Most of MooseX-App behaviour is implemented in metaclass roles. When writing plugins you
       will most likely need to alter/augument the behaviour of these roles. Implementation
       details can be found in the respective packages.

       •   MooseX::App::Meta::Role::Class::Base is applied to the base metaclass

       •   MooseX::App::Meta::Role::Class::Command is applied to the command metaclass

       •   MooseX::App::Meta::Role::Attribute::Option is applied to all attributes in the base
           and command meta classes
