Functions

Implicit and explicit return statements are supported.

fibonacci = def (x)
  if x == 0
    0
  else
    if x == 1
      return 1;
    else
      fibonacci(x - 1) + fibonacci(x - 2);
    end
  end
end

New in 0.11:

Functions can now also be created as named functions:

🚀 > def test()
  puts("test")
end

=> def ()
  puts(test)
end

🚀 > test()
"test"

Multiple Return Values

Functions can return multiple values using comma-separated syntax:

def get_coordinates()
  return 10, 20, 30
end

coords = get_coordinates()
// coords = [10, 20, 30]

This is syntax sugar that automatically wraps the values in an array. The following are equivalent:

return 1, 2, 3
return [1, 2, 3]

The returned array can be unpacked into multiple variables (see Multiple Assignment):

x, y, z = get_coordinates()
// x = 10, y = 20, z = 30
