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,
2022-12-21 01:00:32 +00:00
etc. To find all available hooks thrown by Hilbish, see doc hooks.< / p > < h3 id = functions > Functions< / h3 > < h4 id = catchname-cb > catch(name, cb)< / h4 > < p > Catches a hook with < code > name< / code > . Runs the < code > cb< / code > when it is thrown< / p > < h4 id = catchoncename-cb > catchOnce(name, cb)< / h4 > < p > Same as catch, but only runs the < code > cb< / code > once and then removes the hook< / p > < h4 id = hooksname-- > hooks(name) ->< / h4 > < p > Returns a table with hooks (callback functions) on the event with < code > name< / code > .< / p > < h4 id = releasename-catcher > release(name, catcher)< / h4 > < p > Removes the < code > catcher< / code > for the event with < code > name< / code >

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 > throw(name, … args)< / h4 > < p > Throws a hook with < code > name< / code > with the provided < code > args< / code > < / p > < / div > < div class = "footer mt-auto" > < p class = "card-small text-muted" > Want to help improve this page? < a href = https://github.com/Rosettea/Hilbish/issues/new/choose > Create an issue.< / a > < / p > < / div > < / div > < / div > < footer class = "footer mt-auto mt-auto py-3 bg-light row" > < div class = "col mb-3" > < / div > < div class = "col mb-3" > < a href = /Hilbish class = "d-flex align-items-center mb-3 link-dark text-decoration-none" > < img src = /Hilbish/hilbish-flower.png alt height = 48 class = "d-inline-block align-text-top" > < / a > < p class = text-muted > Rosettea © 2022< br > Made with < i class = "fa-solid fa-heart" style = color:#f6345b > < / i > < / p > < / div > < div class = "col mb-3" > < / div > < div class = "col mb-3" > < / div > < div class = "col mb-3" > < / div > < div class = "col mb-3" > < h5 > Hilbish< / h5 > < ul class = "nav flex-column" > < li class = "nav-item mb-2" > < a href = /Hilbish class = "nav-link p-0 text-muted" > Home< / a > < / li > < li class = "nav-item mb-2" > < a href = /Hilbish/docs/faq class = "nav-link p-0 text-muted" > FAQ< / a > < / li > < li class = "nav-item mb-2" > < a href = https://github.com/Rosettea/Hilbish class = "nav-link p-0 text-muted" > Source< / a > < / li > < li class = "nav-item mb-2" > < a href = https://github.com/Rosettea/Hilbish/releases class = "nav-link p-0 text-muted" > Releases< / a > < / li > < li class = "nav-item mb-2" > < a href = /Hilbish/docs class = "nav-link p-0 text-muted" > Documentation< / a > < / li > < / ul > < / div > < div class = "col mb-3" > < / div > < / footer > < / body > < / html >
