Abstract

This tutorial will introduce you to the Scala. It is intended to enable experienced developers to confidently start programming in Scala. No previous knowledge of Scala is assumed. Although intense, the course ensures you will have a solid understanding of the fundamentals of the language and the tooling.

Content

After having participated in this course you should

be a competent user of Scala constructs in application code
know and be able to apply the functional programming style in Scala
know how to use the fundamental Scala tools
be confident to start using Scala in production applications

Prerequisites

The presentation will frequently be mixed with hands-on exercises that give you a good opportunity to try what you have learnt and a chance to clarify your understanding.

Preparation

Please bring a laptop to the tutorial. Ideally, you should install the required software on your laptop before the tutorial. If that fails, we'll have a machine on-site for you to connect to. In that case, make sure to have an RDP client (a client for Microsoft's Remote Desktop protocol) installed on your laptop, so you can connect to our on-site machine.

If you have problems or questions, please contact Mike Sperber (sperber(at)deinprogramm(dot)de).

Installing the prerequisite software

You will need a machine with Java 6 installed.

Install the TypeSafe Stack.
Verify Verify the installation by opening a terminal and entering scala -version:

Scala code runner version 2.9.2 -- Copyright 2002-2011, LAMP/EPFL

Download and install Eclipse 3.7 (Indigo) for your platform.
Install the Scala plugin Special Edition for Scala 2.10.0-M5 with the menu "Help > Install New Software ...".
Use the following update site: http://download.scala-ide.org/releases-210/milestone/site.
Verify the installation by opening a fresh workspace, e.g. ~/workspaces/training-scala, and switching to the Scala perspective.
Create a directory ~/.sbt/plugins via the command

mkdir -p ~/.sbt/plugins

Create a file plugins.sbt in the directory ~/.sbt/plugins with the following contents:

addSbtPlugin(
  "com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0"
)

In an sbt session, execute the eclipse command, which should produce the following output:
In Eclipse, import the new Eclipse project with the menu "Import ... > Existing Projects into Workspace".
Use the giter8 template typesafehub/training-ftts to create the case study project via the following command:

g8 typesafehub/training-ftts

Accept the default name scalanetworks with the ENTER key.
cd into the new scalanetworks directory.
Start sbt and ceate an Eclipse project with the eclipse command. This should produce the following output:

[info] Successfully created Eclipse project files ...

Import the case study project into your Eclipse workspace.
