Scala: pass Seq to var-args functions

Question

Given a function that takes a variable number of arguments, e.g.

def foo(os: String*) =   println(os.toList) 

How can I pass a sequence of arguments to the function? I would like to write:

val args = Seq("hi", "there") foo(args) 

Obviously, this does not work.

Answer 1

foo(args:_*) does the trick. Instead of applying the sequence as one single argument, each element in the sequence will be used as an argument.
