“With” statement equivalent for Scala?

Question

Idle pondering from a Scala learner perhaps, but ... in my tinkerings I\'ve written the following:

( n.child.size > 0 ) && ( n.child.filter( ! _.isIns         


        

Answer 1

Starting Scala 2.13, the standard library now provides a chaining operation method pipe fitting exactly this need:

import scala.util.chaining._

n.child.pipe(list => list.size > 0 && list.filterNot(_.isInstanceOf[Text]).size == 0)

The value of n.child is "piped" to the function of interest.
