Scrabbλe

A one- or two-player implementation of Scrabble for teaching functional programming at the University of Brighton. It consists of a core library, and two clients (web and CLI) for playing the game.

The Scrabble library is inspired by https://github.com/joshcough/Scrabble.

If you don't know the rules of the game you should begin by reading them here.

The emphasis is on explaining the process of developing a Haskell project with several parts, aimed at students who have already learned Haskell syntax and functional problem solving. Commonly used data structures and libraries like Data.Text, maps, arrays, aeson and lens are explained, as well as monadic error checking and building a WebSocket client to the game that shows how to use threads and other concurrency abstractions safely.

Each chapter refines the initial solution, ending up with something that is (hopefully) a clean, functional design that can easily be extended.

Testing is a continuous topic, so new tests are added in each chapter.

• Chapter One: Getting started.
• Chapter Two: Players and the game.
• Chapter Three: Validating moves.
• Chapter Four: Playing the game.
• Chapter Five: Playing against the computer.
• Chapter Six: The CLI client.
• Chapter Seven: The web server and client.
• Chapter Eight: Configuration and conclusion.
