Functional Programming in Scala

This repository hosts my solutions to the exercises of the book Functional Programming in Scala, from Manning Publications.

The list of exercises and the official solutions can be found at https://github.com/fpinscala/fpinscala

Status

• Completion status of the exercises

You can find the examples at src/main/scala, with a directory (Scala package) for each book chapter.

Tests

For each one of the exercises, I provide a test. Tests are stored in the directory src/test/scala, and you can reuse them for your exercises.

You will need sbt to run the tests and compile the exercises.

To compile the exercises before running the tests, simply run

> compile

If it's the first time, it will download all the necessary dependencies (basically, the Scala Specs2 library).

To run all the tests, simply execute the following in sbt

> test

To run a specific test, execute

> testOnly chapXX.ExYYSpec

where XX is the chapter number, and YY is the exercise number. For instance

> testOnly chap03.Ex10Spec

How to run (some of) the exercises

Some of the exercises can also be run as standalone applications.

To run the exercises in sbt, use

>  runMain package_name.object_name args

For instance

> runMain chap2.Ex02 5

Not all exercises can be run as applications. To check the output for some input values of all the exercises, you can add cases to the tests.
