Dynamic property operator for HOCON
Latest commit 908edcc Jan 20, 2019


This is the experimental fork of Akka.FSharp library, introducing new features such as typed actor refs, and also simplifying existing Akka.FSharp API. The main reason for splitting from official API is to be able to introduce new (also experimental), but possibly breaking changes outside existing Akka release cycle.

Read wiki pages for more info.

Get's started

For more examples check examples section.

Obligatory hello world example:

open Akkling

use system = System.create "my-system" <| Configuration.defaultConfig()
let aref = spawnAnonymous system <| props(actorOf (fun m -> printfn "%s" m |> ignored))

aref <! "hello world"
aref <! 1 // ERROR: we have statically typed actors here

Another example using stateful actors:

open Akkling

use system = System.create "my-system" <| Configuration.defaultConfig()

type Message =
    | Hi
    | Greet of string

let rec greeter lastKnown = function
    | Hi -> printfn "Who sent Hi? %s?" lastKnown |> ignored
    | Greet(who) ->
        printfn "%s sends greetings"
        become (greeter who)

let aref = spawn system "greeter" <| props(actorOf (greeter "Unknown"))

aref <! Greet "Tom"
aref <! Greet "Jane"
aref <! Hi


You can’t perform that action at this time.
