I tend to add is to booleans toreally differentiate between a method name and a status.

def open_file_dialog(self):
    self.dialog_file_is_open = True
    pass

That way, it's easier for my dumb brain to spot which is which at a glance.

In Elixir, we mark statuses by using a question mark at the end of the variable name. Something like this:

authorized? = user |> get_something() |> ensure_authorized?()

I like this better than the is_ prefix

does '?' have type definition in elixir or this is generally agreed design pattern?

If it's like Lisp, then ? is just part of the symbol and doesn't have any special syntatic meaning. In different Lisps it's also convention to end predicate names with a ? or with P (p for predicate)
