Simulate ternary operator in Elixir


How to do the similar conditional one-line check in Elixir?

if (x > 0) ? x : nil

Is this the only equivalent in elixir world?

if true, do: 1, else: 2

Solution

  • To me, the if IS the equivalent of a ternary operator as it evaluates to a value which for various other languages it doesn't.

    so x = if false, do: 1, else: 2

    is basically x = false? 1 : 2

    Not sure why Ruby adopted it ( if you are coming from Ruby ) as it has assignable if statements. in C the ternary is useful as the code bloats with the equivalent if statements. Of course C programmers desperate for terseness went nuts and did many nested upon nested ternaries :)
