Instead of doing this:
defmodule LousyCalculator do
@spec add(number, number) :: {number, String.t}
def add(x, y), do: {x + y, "You need a calculator to do that?!"}
@spec multiply(number, number) :: {number, String.t}
def multiply(x, y), do: {x * y, "Jeez, come on!"}
end
How about this:
defmodule LousyCalculator do
@specdef add(x number, y number) :: {number, String.t} do: {x + y, "You
need a calculator to do that?!"}
@specdef multiply(x number, y number) :: {number, String.t} do: {x * y,
"Jeez, come on!"}
end
