Akkit is a collection of usefull general-purpose Akka actors and modules.

Akkit is published to Sonatype OSSRH, so all you have to do is add the following dependencies to your build.sbt:

libraryDependencies ++= Seq(
  "com.ataraxer" %% "zooowner-core" % "0.1.0",
  "com.ataraxer" %% "zooowner-macro" % "0.1.0")

@safeActor macro annotation adds following entities to actor's companion object:

• props method -- which will accept the same arguments as annotated actor and return an instance of SafeProps[T], where T is a type of annotated actor;
• apply method -- which will accept the same arguments as annotated actor and implicit ActorRefFactory and create a new actor of that type, returning a SafeRef[T], where T is a type of annotated actor;
• Ref type alias -- equivalent to SafeRef[T], where T is a type of annotated actor;
• <actor class name>Ref type alias -- as an alias to Ref.

This allows you to dramatically decrease boilerplate while defining actors, while making sure that you do not enclose over any unwanted state and passing references to correct actors.

@safeActor
class Printer(prefix: String) extends Actor {
  def receive = { case msg => println(prefix -> msg) }
}


@safeActor
class Pinger(printer: Printer.Ref) extends Actor {
  def receive = { case "ping" => printer ! "pong" }
}


object Demo extends App {
  implicit val system = ActorSystem("demo-system")

  val printer = Printer(">>>")
  val pinger = Pinger(printer)

  pinger ! "ping" // results in "ping" printed to stdout
}
