ǎi you (pronounced like ai-yo) is a romanized spelling of the Chinese phrase 哎呦, which is onomatopoeic for the sound made when surprised, as is often the case when programming with side effects.
aiyou provides IO types and classes for Scala.
import cats.data.Kleisli
import cats.implicits._
import aiyou._
import aiyou.implicits._
object MyApp extends SafeApp {
def ioAction: IO[Int] = for {
_ <- IO.print("hello")
_ <- IO.print(" ")
_ <- IO.println("world")
} yield 42
def foo[F[_]: MonadIO]: F[Int] = ioAction.liftIO[F]
override def runl(args: List[String]): IO[Unit] = {
val kleisli = foo[Kleisli[IO, Unit, ?]]
val ioInt = kleisli.run(())
ioInt.void
}
}The aiyou project and contributors support the Typelevel Code of Conduct and want all its associated channels to be a safe and friendly environment for contributing and learning.
aiyou is natively built against Scala 2.10.x, Scala 2.11.x, 2.12.x, Cats 0.8.1, and Scalaz 7.2.x.
The modules of aiyou are (append -cats or -scalaz to get the full module name for the corresponding environment):
core: IO related types and classeslaws: laws for the type classes
resolvers += Resolver.sonatypeRepo("snapshots")
