DESCRIPTION

EVENTS
       Mojo::Log can emit the following events.

   "message"
	 $log->on(message => sub {
	   my ($log, $level, @messages) = @_;
	   ...
	 });

       Emitted when a new message gets logged.

	 $log->unsubscribe('message');
	 $log->on(message => sub {
	   my ($log, $level, @messages) = @_;
	   say "$level: ", @messages;
	 });
