I'm coding a small Akka Streams sample where I want to write elements of a List
to a local TXT file
implicit val ec = context.dispatcher
implicit val actorSystem = context.system
implicit val materializer = ActorMaterializer()
val source = Source(List("a", "b", "c"))
.map(char => ByteString(s"${char} \n"))
val runnableGraph = source.toMat(FileIO.toPath(Paths.get("~/Downloads/results.txt")))(Keep.right)
runnableGraph.run()
The file is already created by the location I set in the code.
I do not terminate the actor system, so definitely it has enough time to write all of List
elements to the file.
But unfortunately, nothing happens
