trait App extends DefaultRuntime

The entry point for a purely-functional application on the JVM.

import zio.App
import zio.console._

object MyApp extends App {

  final def run(args: List[String]) =
    myAppLogic.fold(_ => 1, _ => 0)

  def myAppLogic =
    for {
      _ <- putStrLn("Hello! What is your name?")
      n <- getStrLn
      _ <- putStrLn("Hello, " + n + ", good to meet you!")
    } yield ()
