 use Alien::Build::Plugin;
 use Carp ();
 
 has prop1 => 'default value';
 has prop2 => sub { 'default value' };
 has prop3 => sub { Carp::croak 'prop3 is a required property' };

DESCRIPTION

This document describes the Alien::Build plugin base class. For details on how to write a plugin, see Alien::Build::Manual::PluginAuthor.

CONSTRUCTOR

new

 my $plugin = Alien::Build::Plugin->new(%props);

METHODS

init

 $plugin->init($ab_class->meta); # $ab is an Alien::Build class name

You provide the implementation for this. The intent is to register hooks and set meta properties on the Alien::Build class.

has

 has $prop_name;
 has $prop_name => $default;

Specifies a property of the plugin. You may provide a default value as either a string scalar, or a code reference. The code reference will be called to compute the default value, and if you want the default to be a list or hash reference, this is how you want to do it:

 has foo => sub { [1,2,3] };

meta

 my $meta = $plugin->meta;

Returns the plugin meta object.
