trait App extends RTS

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

import java.io.IOException
import scalaz.zio.{App, IO}
import scalaz.zio.console._

object MyApp extends App {

final def run(args: List[String]): IO[Nothing, ExitStatus] =
    myAppLogic.attempt.map(_.fold(_ => 1, _ => 0)).map(ExitStatus.ExitNow(_))

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

Abstract Value Members

  1. abstract def run(args: List[String]): IO[Nothing, ExitStatus]

  20. final def unsafeRun[E, A](io: IO[E, A]): A

    Awaits for the result of the fiber to be computed.

    Awaits for the result of the fiber to be computed. In Javascript, this operation will not, in general, succeed because it is not possible to block for the result. However, it may succeed in some cases if the IO is purely synchronous.

    Runs the io asynchronously.
