Can't get TagAPI to load

[NigelThorne]

My plugin https://gist.github.com/3847484 tries to hook into the TagAPI plugins events... but I get errors.

ok fixed it.. I didn't even have the TagAPI library loaded.. https://gist.github.com/3844656 is the working code. Now to work out how to make the TagAPI optional.

[enebo]

Ah I need to update the events list. Unfortunately the new annotations support for Bukkit events means having to periodically update this list of classes.

[enebo]

Oh crap. I just realized that this is an external lib which adds its own events....ugh. Ok. I will try and figure out how we can detect these event classes so we can auto-hookup these (might not be possible).

[NigelThorne]

Yes I don't mind the monkey patching to add in the custom event. I'd love to be able to only do it if the plugin is loaded though. Any idea how I can do that?

Nigel, This is still cruddy but better than before. If you know you want to consume new events you still need to make your own listener

[enebo]

Nigel, you still need to make your own listener but now things should be quite a bit less painful:

require 'purugin/event'

extend Purugin::EventDefiner

define_event_listener('TheEventType', 'the.event.package')

This should make the class for you and register under the event map as the same name. Hopefully this makes things slightly less painful.

[NigelThorne]

Like it. Nice!
