Clear in scala (call cls in scala program running in cmd )

Question

In python this works:

 clear = lambda: os.system('cls')
 clear()

How would I do that in scala?

For REPL there is :keybindings, Ctrl + L clears the screen.

Using REPL started from a bash shell:

scala> import scala.sys.process._
import scala.sys.process._

scala> def clear() = "clear".!
clear: ()Int

scala> clear()

This doesn't seem to work using REPL stated from cmd window in windows though. – Carl Oct 11 '14 at 18:56

How about print("\u001b[2J")?

Nice! Or `print("\u001b[2J"); print("\u001b[H")` seems to have the same behavior as `"clear.!` mentioned above (clear console and move to the top left). – Tyler Sep 08 '19 at 21:27

use this code. print("\033c") this removes all charset

it will clear away everything in the Scala REPL.
