NAMEAlien::Build::Plugin - Plugin base class for Alien::BuildVERSIONversion 2.48SYNOPSISCreate your plugin:package Alien::Build::Plugin::Type::MyPlugin; 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' }; sub init { my($self, $meta) = @_; my $prop1 = $self->prop1; my $prop2 = $self->prop2; my $prop3 = $self->prop3; $meta->register_hook(sub { build => [ '%{make}', '%{make} install' ], }); } From your alienfile use alienfile; plugin 'Type::MyPlugin' => ( prop2 => 'different value', prop3 => 'need to provide since it is required', ); DESCRIPTIONThis document describes the Alien::Build plugin base class. For details on how to write a plugin, see Alien::Build::Manual::PluginAuthor.Listed are some common types of plugins:
CONSTRUCTORnewmy $plugin = Alien::Build::Plugin->new(%props); PROPERTIESinstance_idmy $id = $plugin->instance_id; Returns an instance id for the plugin. This is computed from the class and arguments that are passed into the plugin constructor, so technically two instances with the exact same arguments will have the same instance id, but in practice you should never have two instances with the exact same arguments. METHODSinit$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. subpluginDEPRECATED: Maybe removed, but not before 1 October 2018.my $plugin2 = $plugin1->subplugin($plugin_name, %args); Finds the given plugin and loads it (unless already loaded) and creats a new instance and returns it. Most useful from a Negotiate plugin, like this: sub init { my($self, $meta) = @_; $self->subplugin( 'Foo::Bar', # loads Alien::Build::Plugin::Foo::Bar, # or throw exception foo => 1, # these key/value pairs passsed into new bar => 2, # for the plugin instance. )->init($meta); } hashas $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] }; metamy $meta = $plugin->meta; Returns the plugin meta object.
