NAME Plugin::Tiny - A tiny plugin system for perl VERSION version 0.002 SYNOPSIS #from core or bundling plugin use Moose; #optional, t/tiny.t avoids using moose in core use Plugin::Tiny; has 'plugins'=>( is=>'ro', isa=>'Plugin::Tiny', default=>sub{Plugin::Tiny->new()} ); #load plugin_class (and perhaps phase) from your configuration $self->plugins->register( phase=>$phase, #optional; defaults to last part of plugin class plugin=>$plugin_class, #required role=>$role, #optional arg1=>$arg1, #optional arg2=>$arg2, #optional ); #execute your plugin's methods my $plugin=$self->get_plugin ($phase); $plugin->do_something(@args); DESCRIPTION Plugin::Tiny is minimalistic plugin system for perl. Each plugin is associated with a keyword (referred to as phase). A limitation of Plugin::Tiny is that each phase can have only one plugin. Bundles of Plugins You can still create bundles of plugins if you hand the plugin system down to the (bundeling) plugin. That way, you can load multiple plugins for one phase (althoughyou still need distinct phase labels for each plugin). #in your core $self->plugins->register( phase=>'Scan', plugin=>'Plugin::ScanBundle', plugins=>$self->plugins, #plugin system ); #in Plugin::ScanBundle has 'plugins'=>(is=>'ro', isa=>'Plugin::Tiny', required=>1); $self->plugins->register (plugin=>'Plugin::Scan1'); $self->plugins->register (plugin=>'Plugin::Scan2'); my $scan1=$self->plugins->get('Scan1'); $scan1->do_something(@args); Require a Plugin Role You may want to do a plugin role for all you plugins, e.g. to standardize an interface etc. ATTRIBUTES prefix Optional init argument. You can have the prefix added to all plugin classes you register so save some typing and force plugins in your namespace: #without prefix my $ps=Plugin::Tiny->new $ps->register(plugin='Your::App::Plugin::Example1'); $ps->register(plugin='Your::App::Plugin::Example2'); #with prefix my $ps=Plugin::Tiny->new ( prefix=>'Your::App::Plugin::' ); $ps->register(plugin='Example1'); $ps->register(plugin='Example2'); role Optional init argument. A default role to be applied to all plugins. Can be overwritten in register. METHODS $plugin_system->register(phase=>$phase, plugin=>$plugin_class); Optionally, you can also specify a role which your plugin will have to be able to apply. Remaining key value pairs are passed down to the plugin constructor: $plugin_system->register ( phase=>$phase, #optional. Defaults to last part of plugin_class plugin=>$plugin_class, #required role=>$role, #optional plugins=>$plugin_system, #optional args=>$more_args, #optional ); A side-effect is that your plugin cannot use 'phase', 'plugin', 'role' as named arguments. Returns the newly created plugin object on success. Confesses on error. my $plugin=$self->get_plugin ($phase); Returns the plugin object associated with the phase.
