Instance Method Details

#hook(names, &block) ⇒ Object

Install a hook. Leads to eventually calling the relavent hook generator. The anmes argument takes one key-value pair e.g. => :settings_changed, this would mean the hook generator named ‘goto’ and it should create a hook event called ‘settings_changed’. The block is then passed on to each hook generator. See the docs on hooks.md for information on what each block function takes
