Pedagogically appropriate functions for user input handling in Scala (sans exceptions!)
To use Scala-UI in your sbt-based project, add these lines to your build.sbt
scalaVersion := "2.11.5"
resolvers += "loyolachicagocode@bintray" at "http://dl.bintray.com/loyolachicagocode/maven"
libraryDependencies += "edu.luc.cs" %% "introcs-scala-ui" % "x.y.z"
where x.y.z is the most recent version number of this package available on
Bintray.
import edu.luc.cs.ui._
val n = promptInt("What is your favorite number? ", -1)
println(s"Thank you for entering the number $n.")
$ sbt test:run
...
What is your favorite number? 7
Thank you for entering the number 7.
