Key Updates

1. MinimalActorContext in FSM StateManager

Contribution by: @Mitrug

• Summary:

  • Introduced MinimalActorContext in FSM StateManager to allow child actor creation and self-messaging within FSMs.
  • Removed ActorSystem from MinimalActorContext to restrict scheduler access, ensuring controlled state transitions.
  • Updated FaultHandler to use ActorContext instead of the minimal context for full access to the ActorSystem.

• Example:

  FSM[IO, FsmParentState, Int, FsmRequest, Any]
    .when(FsmIdle) {
      case (Event(FsmRun, _), sM) =>
        for {
          fsmChildActor <- sM.minimalContext.actorOf(FsmChild())
          result <- fsmChildActor ? FsmChildEcho
          state <- sM.goto(FsmRunning).replying(result)
        } yield state
    }
    .when(FsmRunning) {
      case (Event(FsmRun, _), sM) =>
        (sM.minimalContext.self ! FsmStop) *> sM.stay()
      case (Event(FsmStop, _), sM) =>
        stopped.complete(true) *> sM.stay()
    }
    .withConfig(FSMConfig.withConsoleInformation)
    .startWith(startWith, 0)
    .initialize

2. Curried State Manager in FSMs

Contribution by: @PetrosPapapa

• Summary:

  • Simplified state function type signatures by currying the state manager, reducing repetition and aligning syntax closer to Akka.

• Example:

  Before:

  def someStateFunction: PartialFunction[(FSM.Event[Any, Request], StateManager), IO[State]] = {
    case (FSM.Event(Start, _), stateManager) => stateManager.goto(Active)
    case (FSM.Event(Stop, _), stateManager) => stateManager.stay()
  }

  After:

  def someStateFunction: StateManager => PartialFunction[FSM.Event[Any, Request], IO[State]] = stateManager => {
    case FSM.Event(Start, _) => stateManager.goto(Active)
    case FSM.Event(Stop, _) => stateManager.stay()
  }

These updates enhance FSM flexibility and usability. We encourage users to integrate these changes and report any feedback.

v1.0.0

We are excited to announce the first major release of Cats-Actors, a functional programming-based actor system built on Cats Effect and FS2. This release introduces a robust and highly concurrent actor model, leveraging fibers for efficient concurrency management. Major features include:

• Full integration with Cats Effect for composable, asynchronous programming.
• High concurrency with minimal overhead using fibers.
• Seamless interoperation with FS2 for streaming data processing.

Thank you to all contributors and users who helped shape this release. We look forward to your feedback and contributions to further improve Cats-Actors!
