Daily scala

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

This is the start of a series of posts on Scala-IO. Scala-IO is as the name implies a library for performing input and output operations with Scala. There are 4 main facets to the library

• Basic IO - Reading and writing to some underlying resource. The current implementation is Java based and thus allows reading and writing to resources like java.io.Readers, Writers, Channels, Streams, etc...
• File API - A library loosely designed after java 7 nio.file API with an additional simple unix like DSL for traversing and searching the filesystem. It is a pluggable architecture which allows plugins for systems like WebDav or Zip filesystems to be addressed in a similar manner as the local filesystem. The included implementation is for the local file system and is implemented on the java.io APIs
• Asynchronous Access - Throughout the APIs are both synchronous and asynchronous options allowing both models of programming to be easily used.
• In the 2.10.x + versions the future implementations are pluggable but require no additional libraries if so that is the desire
• In 2.9.x versions there are two different dependencies one with asynchronous APIs implemented on Akka and one without any asynchronous APIs
• Processor API - An API for defining complex IO processes declaratively.
