One of the leading textbooks on Haskell programming, this third edition is thoroughly revised throughout and includes new material on testing and domain-specific languages and a variety of new examples and case studies, including simple games. * Emphasises software engineering principles. * Encourages a disciplined approach to building reusable libraries of software components. * Case studies are used throughout the book to introduce new ideas, illustrate important concepts, and demonstrate how existing techniques work together. Case studies include: - An interactive calculator programme. - A coding and decoding system. - A small queue simulation package. * Companion website contains supporting material (such as visualisation tools * and a substantial number of web links) to aid further study. Appendices contain information on Hugs errors.

This book teaches functional programming as a way of thinking and problem solving, using Haskell, the most popular purely functional language. Rather than using the conventional mathematical examples commonly found in other programming language textbooks, the author draws examples from multimedia applications, including graphics, animation, and computer music, thus rewarding the reader with working programs for inherently more interesting applications. Aimed at both beginning and advanced programmers, this tutorial begins with a gentle introduction to functional programming and moves rapidly on to more advanced topics. An underlying theme is the design and implementation of domain specific languages, using three examples: FAL (a Functional Animation Language), IRL (an Imperative Robot Language), and MDL (a Music Description Language). Details about programming in Haskell are presented in boxes throughout the text so they can be easily referred to and found quickly.
