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.< / p > < h3 id = functions class = heading > Functions
< a href = #functions class = heading-link > < i class = "fas fa-paperclip" > < / i > < / a > < / h3 > < h4 id = catchname-cb class = heading > catch(name, cb)

For this to work, < code > catcher< / code > has to be the same function used to catch
an event, like one saved to a variable.< / p > < h4 id = throwname-args class = heading > throw(name, … args)
