Scala-IO Getting Started

For the next several posts you will need to have Scala-IO installed and probably should have a sbt project as well.

There are currently 2 Scala-IO 0.4 releases.

• Scala-io 0.4-seq - A version of Scala 0.4 without the Akka dependency and therefore no ASync support
• Scala-io 0.4 - The full version that contains an Akka  dependency

The Scala 2.10 versions will have no Akka dependency but can optionally use Akka.

So getting started:

Download the example project on the docs website (http://jesseeichar.github.com/scala-io-doc/latest):

• Go to Getting Started and follow instructions for downloading and running the example project.  The following goes through the steps for the 0.4.1 instructions.

sbt console   scala> import scalax.io._ import scalax.io._   scala> import java.net.URL import java.net.URL   scala> Resource.fromURL(new URL("http://www.scala-lang.com")).      | lines().async.size.onComplete(println) res3: akka.dispatch.Future[Int] = akka.dispatch.DefaultPromise@363adfb4   scala> Right(770)

The last line (Right(770)) is not a command to enter; it is the result of the asynchonous call.
