Module bait

the event emitter

Introduction

Bait is the event emitter for Hilbish. Why name it bait? Why not. It throws hooks that you can catch. This is what you will use if you want to listen in on hooks to know when certain things have happened, like when you’ve changed directory, a command has failed, etc. To find all available hooks thrown by Hilbish, see doc hooks.

Functions

catch(name, cb)

Catches a hook with name. Runs the cb when it is thrown

catchOnce(name, cb)

Same as catch, but only runs the cb once and then removes the hook

hooks(name) -> table

Returns a table with hooks (callback functions) on the event with name.

release(name, catcher)

Removes the catcher for the event with name. For this to work, catcher has to be the same function used to catch an event, like one saved to a variable.

throw(name, …args)

Throws a hook with name with the provided args
