    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()
    }
  }
}
