String interpolation in Scala?

Question

I wanted to ask if there is any type of string interpolation in Scala. I have made a search on the subject but \'till now I have found that there is no string interpolation.

Answer 1

You can do it C-style:

"Interpolate my %s here" format List(1,2,3)

//String = Interpolate my List(1, 2, 3) here

or

List(1,2,3) formatted "Interpolate my %s here"

You can use these on anything with a toString (i.e. anything)

case class Foo(n: Int)
Foo(42) formatted "Here is a %s !!!!"
//String = Here is a Foo(42) !!!!

although the former is more flexible in terms of enabling multiple interpolations in a single string (since it can take multiple arguments).
