If available in Hex, the package can be installed
by adding ex_signal to your list of dependencies in mix.exs:
def deps do
[
{:ex_signal, "~> 0.1.0"}
]
end defmodule SignalsDemo do
# The result of any function decorated as a signal
# is sent to the receivers of the named signal
@signal("some_signal_name")
def foo() do
:foo
end
# Receiever is any arity 1 function
# Gets called with the result of the sender
@receiver("some_signal_name")
def bar(foo) do
IO.inspect("Recieved #{foo}")
end
end
