Scala for Java Developers (1/2) (Laptops Optional)

Workshop Requirements

This session is a workshop. Please come prepared.

Some things will be required if you to participate in the workshop

• A modern JDK installation. JDK 1.8+ will suffice. Remember that it should be a JDK and not a JRE!
• Your JDK should be mapped properly to JAVA_HOME and your PATH variables.
• An installation of your favorite IDE or editor.
• An inquisitive mind.

Unfortunately, Internet connectivity is sometimes a dicey affair and at times it can rain on our parade. To avoid having to wait for the install at the conference, you can prepare Scala before the conference! If you don't have the opportunity to do this, we will have either memory sticks or private networks at the conference. But it is preferred to do the installation before the event.

For MacOSX:

• Download brew package manager at http://brew.sh
• At a console type: brew install scala

For Windows

• Visit http://scala-lang.org/download
• Download the .msi package
• Install the .msi package

For Linux

• Download the tar.gz package
• Extract the package to your favorite directory
• Export SCALA_HOME to your Scala directory (scala-2.11.x)
• Add to your PATH: $SCALA_HOME/bin

You may also want to take the opportunity to load some Scala Plugins onto your favorite IDE and Editor. Below is a list of resources that you can use to enhance your environment so that you can enjoy Scala syntax highlighting and other helpful tools like refactoring, debugging and analysis.

Eclipse - The Eclipse has an IDE plugin for Scala called aptly Scala-IDE. You can either download the complete Scala IDE which includes the complete Eclipse download. You can also download the plugin. All the information about the plugin can be found at http://scala-ide.org including an easy to follow along video located at http://scala-ide.org/docs/current-user-doc/gettingstarted/index.html. Scala-IDE is also available at the Eclipse Marketplace, although I would recommend getting the latest instructions from scala-ide.org

IntelliJ - IntelliJ has a Scala plugin that can be found by going to Settings -> Plugins, clicking on 'Browse Repositories' button and searching for the 'Scala' plugin on the left. Right click on the 'Scala' and choose 'Install'. IntelliJ will prompt you to restart the IDE, do so, and enjoy.

NetBeans - Currently, Github user 'dcaoyuan' hosts a NetBeans Scala plugin at the address: https://github.com/dcaoyuan/nbscala. I have not tried this out since the number of NetBeans users has shrunk in recent years. If you are an avid NetBeans user and wish to try it, you can let me know the results during the session. There is additional information at http://wiki.netbeans.org/Scala

Emacs - Github user 'aemoncannon' has created 'ENSIME' (Enhanced Scala Interaction Mode for Emacs) at the address and has a great following. https://github.com/aemoncannon/ensime with some documentation at http://aemoncannon.github.io/ensime.

VIM - For VIM users you can use https://github.com/derekwyatt/vim-scala as a VIM plugin that offers Scala color highlighting

VSCode - Download the “Scala Language Plugin” from the plugins within VSCode.

That is it. Hope to see you soon.
