Ruby: how to splice an array into a list Lisp-style?

Question

This is something I find myself wanting to do occasionally. Say I have a list of arguments. In Lisp, I can go like

`(imaginary-function ,@args)

in order to call the function with the array turned from one element into the right number of arguments.

Is there similar functionality in Ruby? Or am I just using a completely wrong idiom here?

Answer 1

Yes! It's called the splat operator.

a = [1, 44]
p(*a)

Answer 2

This is the splat operator: function(*list)
