* addunidoc task via an AutoPlugin that depends on PrValidation and Unidoc autoplugins
* separate cli option logic to a case class
* remove autoplugin for root project
This greatly simplifies the Receptionist by providing the ability to
express a polymorphic map that calculates the type of each value from
the type of its key. Another possible use of this map is to express the
Extensions map in a type-safe fashion (no casts needed).
This is the first step towards more type-safety in Actor interactions,
comprising:
* generic ActorRef[T] that only accepts T messages
* generic ActorSystem[T] extends ActorRef[T] (sending to the guardian,
whose Props[T] are provided for ActorSystem construction)
* removed the Actor trait: everything in there has been made into
messages and signals
* new Behavior[T] abstraction that consumes messages (of type T) or
Signals (lifecycle hooks, Terminated, ReceiveTimeout, Failed),
producing the next Behavior[T] as the result each time
* the ask pattern is provided and yields properly typed Futures
* variants of ActorContext are provided for synchronous testing of
Behaviors
All of this is implemented without touching code outside akka-typed
(apart from making guardianProps configurable), creating wrapper objects
around ActorRef, ActorContext, ActorSystem, Props and providing an Actor
implementation that just runs a Behavior.
