sg-scala-labs's Introduction

Singapore Scala lab

This repository, intended for the Spring User Group Meetup on 28th Sep 2016, is an introductory lab to the scala language.

It is a patchwork of exercises taken from scala-labs and the Coursera course Functional Programming Principles in Scala.

Before starting the lab, make sure to setup your environment (section below) and optionally go through this Scala quick tour.

Environment Setup

First make sure a version of the JDK is installed. Preferably java 8, although Java 6 and 7 will work too with scala-2.11.x used in this lab.

$ java -version
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

Then install the latest version of SBT (stands for "Simple Build Tool") the de facto build tool for Scala applications. After adding the sbt command to your PATH, validate with the command line
```
$ sbt about
[info] Set current project to redmart (in build file:/Users/redmart/)
[info] This is sbt 0.13.12
...
```
Finally Install a scala-compatible IDE, for example
- IntelliJ IDEA Community edition
- Scala IDE for Eclipse
Optionally, it is good to install Scala itself so you have access to its command-line REPL for experimenting

Start the lab

Clone this repo

$ git clone https://github.com/damien-neveu/sg-scala-labs.git

Navigate to the sg-scala-labs folder and compile the project
- $ cd sg-scala-labs/
- $ sbt clean compile
Open the project within your IDE
- In IntelliJ : File -> Open -> /path/to/folder/sg-scala-labs -> Choose SBT -> Check Auto-Import only -> OK
Fix all exercises so their tests pass
- $ sbt test
