    Provides scala API for 'go-like' CSP channels.

    Provides scala API for 'go-like' CSP channels.

    Overview

    see readme for quick introduction.

    Usage

    At first you must receive gopherApi as Akka extension:

    import gopher._

.....
val gopherApi = Gopher(actorSystem)

    Then you can use CPS channels with blocling operations inside go clauses:

    val channel = gopherApi.makeChannel[Long]
val n = 10000
val producer = go {
 @volatile var(x,y) = (0L,1L)
 for( s <- gopherApi.select.forever) {
   case z: channel.write if (z==x) =>
              x = y
              y = x+z
              if (x > n) {
                 channel.close
                 implicitly[FlowTermination[Unit]].doExit()
              }
 }
}
val consumer = for((c,i) <- channel.zip(1 to n)) {
   Console.println(s"fib(${i})=${c}")
}
Await.ready(consumer, 10 seconds)

    and defer/recover in go/goScope

    goScope{
  val f = openFile(myFileName)
  defer{
    if (! recover{case ex:FileNotFoundException => Console.println("invalid fname")}) {
       f.close()
    }
  }
}

  • trait Transputer extends AnyRef

    Reusable unit of application structure, which consists from set of input ports, set of output ports and behaviour

    Reusable unit of application structure, which consists from set of input ports, set of output ports and behaviour

    Transputers can be created as elementary behaviour, descibed by select statement and then can be combined into larger structures

    Transputers can be recovered from execeptions (i.e. transputer can be restarted or resume execution) or escalated to parent transputers or root superviser.

    async incarnation of fold.

    async incarnation of fold. Fold return future, which successed when channel is closed. Operations withing fold applyed on result on each other, starting with s0. val fsum = ch.afold(0){ (s, n) => s+n } Here in fsum will be future with value: sum of all elements in channel until one has been closed.
