Scala Automatic Resource Management

This project is an attempt to provide an Automatic-Resource-Management library for the scala distribution. It is based off of code contributed to the Scalax project.

Using scala-arm

In SBT:

libraryDependencies += "com.jsuereth" %% "scala-arm" % "1.4"

or (if you want to manually specify the Scala version for some reason)

libraryDependencies += "com.jsuereth" % "scala-arm_2.9.2" % "1.4"
libraryDependencies += "com.jsuereth" % "scala-arm_2.10" % "1.4"
libraryDependencies += "com.jsuereth" % "scala-arm_2.11" % "1.4"

In Maven:

<dependency>
   <groupId>com.jsuereth</groupId>
   <artifactId>scala-arm_${scala.binary.version}</artifactId>
   <version>1.4</version>
</dependency>

Examples

Scala-arm provides a way of managing resources and re-using code. Here's an example:

    import resource._
    // Copy input into output.
    for {
      input <- managed(new java.io.FileInputStream("test.txt"))
      output <- managed(new java.io.FileOutputStream("test2.txt"))
    } {
      val buffer = new Array[Byte](512)
      def read(): Unit = input.read(buffer) match {
        case -1 => ()
        case  n =>
          output.write(buffer,0,n)
          read()
      }
      read()
    }
