Description
Even though there is currently only a single event (output) that can be subscribed to on
CommandRunner, there are two different methods for subscribing:subscribe_eventmethod for registering handlers for eventsregister_output_handlermethod for registering handlers for output eventsLikewise, there are two different methods for notifying the handlers that an event has taken place:
post_eventmethod for eventspost_outputmethod for output eventsThis PR unifies the treatment of output events and general events, i.e. output events are treated no differently than any other event. This makes the
CommandRunnerinterface slimmer and more consistent but also allows for extensibility when additional event types might be added. Event handlers are still callables but now expect the event as their argument (carrying all necessary information to handle the event, e.g. the output, within the passed argument).Resolved issues
