Scala Summer School Content

Here you find the lectures and exercises for the Scala Summer School. It is still Work In Progress (WIP) and only a subset of all lectures and exercises are available.

Table of Contents

1. Introduction
2. Scala 101
3. Functional Programming 101
4. Standard Library
5. Type Classes
6. Type Class Incarnations

All lectures are based on [reveal.js]. Therefore, to navigate use your arrow keys. Chapters are organized in columns, slides in rows. To get an overview of all slides within a lecture press ESC.

Preparations

Mandatory

Before you can start you have to install the following tools:

1. JDK 8 or newer (I think the latest stable version is 10)
2. Scala
3. SBT - it is the build-tool we will use
4. git clone this repository

You have to install it in that order because each tool relies on the tools installed before.

Optional

• Ammonite - this is an enhanced REPL which makes it easier to fiddle around with some code. But you don't need it. Scala comes already with a REPL. But it isn't that great :).

SBT

Here, you find a list of useful SBT commands:

# start SBT in the repo root and keep it running
sbt

# show all sub-projects
sbt> projects

# switch to a sub-project
sbt> project <name of sub-project>

# compile
sbt> compile

# compile on every file change
sbt> ~compile

# run test
sbt> test

# run a certain test
sbt> test:testOnly <name of test>

If you want some more information take a look into the introduction slides.

Build the Lectures

To build a lecture go through the following steps:

$> cd /path/to/repo
$> sbt
# select one of the shown lecture
sbt> project
sbt> project scala101-lecture

# minimum JS optimizations
sbt> fastCompile

# maximum JS optimizations (Github page)
sbt> fullCompile
sbt> exit

# opens lecture in default browser
$> open lecture1_scala_101/index.html
