Some help needed with guard expression in Elixir

Question

I am trying to write a guard expression for my function which will not accept char lists, so I do this:

def myfunction(path) when is_list(path) do

the problem here is that is_list also returns true when a character list such as 'path' is given, how would I go about this?

Answer 1

You could try is_binary. Will return true for Strings, false for Lists in the way you define it.
