Call an elixir method dynamically

elixir

If you have the need to dynamically call a method in elixir, of course there is a method for that, which is called apply (apply/2, apply/3), which optionally takes a module as first parameter, and an atom as second, and a list of arguments a third.

Here are some neat examples:

apply(fn x -> x * 2 end, [2])

defmodule Test do
  def one, do: IO.puts("one")
  def two, do: IO.puts("two")
end

[:one, :two] |> Enum.each(fn method -> apply(Test, method, []) end)
