SYNOPSIS ======== use OO::Plugin; use OO::Plugin::Manager; class Foo is pluggable { has $.attr; method bar is pluggable { return 42; } } plugin Fubar { method a-bar ( $msg ) is plug-around( Foo => 'bar' ) { $msg.set-rc( pi ); # Will override &Foo::bar return value and prevent its execution. } } my $manager = OO::Plugin::Manager.new.initialize; my $instance = $manager.create( Foo, attr => 'some value' ); say $instance.bar; # 3.141592653589793 DESCRIPTION =========== With this framework any application can have highly flexible and extensible plugin subsystem with which plugins would be capable of: * method overriding * class overriding (inheriting) * callbacks * asynchronous event handling The framework also supports: * automatic loading of plugins with a predefined namespace * managing plugin ordering and dependencies Not yet supported but planned for the future is plugin compatibility management.
