[Feature request] Add code highlighting for String interpolation in Scala

[jeanmarc]

I would like to know if it is possible to add highlighting of code that is part of Scala's string interpolation:

  val data = lines.map(_.toInt).sliding(2).toList
  println(s"We have ${data.size} pairs")

The part between ${ and } in a string that starts with s" should be highlighted as if it is actual code.

Yes, it's possible. I'll add it next week.

That sounds great. Do you know the Scala syntax for string interpolation? The string must be prefixed wits s or f, and then can contain $var and ${expression} parts (plus a formatting suffix in case of an f prefix). More info on https://docs.scala-lang.org/overviews/core/string-interpolation.html
