We just fixed an issue where some Scala projects were being misclassified as Java projects. Now, recent projects like Twitter’s FlockDB and Gizzard show up in the Scala language dashboard as they should.

package examples

/** Quick sort, functional style */
object sort1 {
  def sort(a: List[Int]): List[Int] = {
    if (a.length < 2)
      a
    else {
      val pivot = a(a.length / 2)
      sort(a.filter(_ < pivot)) :::
           a.filter(_ == pivot) :::
           sort(a.filter(_ > pivot))
    }
  }
  def main(args: Array[String]) {
    val xs = List(6, 2, 8, 5, 1)
    println(xs)
    println(sort(xs))
  }
}

You can also use Scala syntax highlighting in Gist now. It’s bonus.
