fmt.Sprintf passing an array of arguments

Question

Sorry for the basic question. I'd like to pass a slice as arguments to fmt.Sprintf. Something like this:

values := []string{"foo", "bar", "baz"}
result := fmt.Sprintf("%s%s%s", values...)

And the result would be foobarbaz, but this obviously doesn't work.

(the string I want to format is more complicated than that, so a simple concatenation won't do it :)

So the question is: if I have am array, how can I pass it as separated arguments to fmt.Sprintf? Or: can I call a function passing an list of arguments in Go?

Answer 1

As you found out on IRC, this will work:

values := []interface{}{"foo", "bar", "baz"}
result := fmt.Sprintf("%s%s%s", values...)

Your original code doesn't work because fmt.Sprintf accepts a []interface{} and []string can't be converted to that type, implicitly or explicitly.
