  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.
