Plugin hooks
From SqueezeboxWiki
Each level in the SlimServer menu hierarchy is considered a "mode" by the SlimServer. Each time the server is started, it reads the Plugins directory for modules. Each is added, by name, into a list. Each Plugin is given a mode, and a set of functions that are defined within that module. The plugins can each be enabled or disabled at will from the web interface. The plugin module itself must define a mode and functions in a form that the server is expecting. This comes from two functions: sub setMode() and sub getFunctions(). A third subroutine, sub getDisplayName() is required to provide the name that the server should display for the plugin. Simple examples of these three functions are below. We will now build a template based on these main functions.
Example 1:
sub setMode { my $client = shift; $client->lines(\&lines); }
sub getFunctions { return \%functions; }
sub getDisplayName { return "MY_PLUGIN_NAME_TOKEN"; }
