I’m using Perl’s PoCo::PluginManager module for plugins in Harlie’s plugins and unfortunately, whilst the documentation on CPAN covers all the code necessary for a plugin, it does not give an example of how to write the code for the application side (E.g. The program loading/unloading a plugin.), and it seems the author has gone missing. So, I have written an example to help anyone who hasn’t managed to figure it out. (It took me a day of dismantling the module to figure out how it worked, I know, I’m slow.)
(Assume that there’s a plugin called Test.pm in a subdirectory called Plugins, which prints debugging output when it’s loaded and unloaded. (You can grab an example of a plugin from the POE::Component::PluginManager page
use warnings;
use POE;
use POE::Component::PluginManager;
POE::Component::PluginManager->new();
POE::Kernel->post('pluginmanager','register');
POE::Kernel->run;
POE::Kernel->post('pluginmanager','load','./Plugins/Test.pm');
print STDERR "Plugin Loaded.";
POE::Kernel->post('pluginmanager','unload','./Plugins/Test.pm');
print STDERR "Plugin Unloaded.";
POE::Kernel->post('pluginmanager','shutdown');
print STDERR "PluginManager shut down";
return 0;
