Take your Haskell and functional programming skills to the next level by exploring new idioms and design patterns About This Book Explore Haskell on a higher level through idioms and patterns Get an in-depth look into the three strongholds of Haskell: higher-order functions, the Type system, and Lazy evaluation Expand your understanding of Haskell and functional programming, one line of executable code at a time Who This Book Is For If you're a Haskell programmer with a firm grasp of the basics and ready to move more deeply into modern idiomatic Haskell programming, then this book is for you. What You Will Learn Understand the relationship between the “Gang of Four” OOP Design Patterns and Haskell Try out three ways of Streaming I/O: imperative, Lazy, and Iteratee based Explore the pervasive pattern of Composition: from function composition through to high-level composition with Lenses Synthesize Functor, Applicative, Arrow and Monad in a single conceptual framework Follow the grand arc of Fold and Map on lists all the way to their culmination in Lenses and Generic Programming Get a taste of Type-level programming in Haskell and how this relates to dependently-typed programming Retrace the evolution, one key language extension at a time, of the Haskell Type and Kind systems Place the elements of modern Haskell in a historical framework In Detail Design patterns and idioms can widen our perspective by showing us where to look, what to look at, and ultimately how to see what we are looking at. At their best, patterns are a shorthand method of communicating better ways to code (writing less, more maintainable, and more efficient code). This book starts with Haskell 98 and through the lens of patterns and idioms investigates the key advances and programming styles that together make "modern Haskell". Your journey begins with the three pillars of Haskell. Then you'll experience the problem with Lazy I/O, together with a solution. You'll also trace the hierarchy formed by Functor, Applicative, Arrow, and Monad. Next you'll explore how Fold and Map are generalized by Foldable and Traversable, which in turn is unified in a broader context by functional Lenses. You'll delve more deeply into the Type system, which will prepare you for an overview of Generic programming. In conclusion you go to the edge of Haskell by investigating the Kind system and how this relates to Dependently-typed programming. Style and approach Using short pieces of executable code, this guide gradually explores the broad pattern landscape of modern Haskell. Ideas are presented in their historical context and arrived at through intuitive derivations, always with a focus on the problems they solve.

This book is a guide on how one can program in Haskell. Haskell is a pure functional programming language. The book begins by giving you a brief overview of the Haskell programming language so that you may know what it is. You are then guided on how to get started with Haskell programming. This involves setting up the Glasgow Haskell compiler which forms the heart of programming in Haskell. You are also guided on how to compile your Haskell scripts. Haskell marks the first programming language to introduce typeclasses into programming. This book explores this in detail. In Haskell, expressions are a common feature when writing scripts. This book guides you on how to use Haskell compiler so as to determine the kind of expression that you have written. Type variables are explored in detail. There are several typeclasses in Haskell. Most of these have been discussed in this book, and you are shown how to use each of those classes. Higher order functions are also examined. In Haskell, functions should only take one parameter. However, it is possible for one to override this mechanism and create a function with more than one parameter. This is usually done using curried functions. This book guides you on how to implement such functions in your code. This book guides you on how to implement the Lambda functions in Haskell. Input and output forms a significant part in any programming language. You are guided on how to obtain user data in Haskell and then provide them with output based on that input. The following topics are discussed in this book: - What is Haskell? - Getting Started - Types and Types and Typeclasses in Haskell - Higher Order Functions - Modules - Input and Output - Zippers

Introducing functional programming in the Haskell language, this book is written for students and programmers with little or no experience. It emphasises the process of crafting programmes, problem solving and avoiding common programming pitfalls. Covering basic functional programming, through abstraction to larger scale programming, students are lead step by step through the basics, before being introduced to more advanced topics. This edition includes new material on testing and domain-specific languages and a variety of new examples and case studies, including simple games. Existing material has been expanded and re-ordered, so that some concepts – such as simple data types and input/output – are presented at an earlier stage.

Functional programming is a style of programming that emphasizes the use of functions (in contrast to object-oriented programming, which emphasizes the use of objects). It has become popular in recent years because of its simplicity, conciseness, and clarity. 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 (boring) mathematical examples commonly found in other programming language textbooks, the author uses examples drawn 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. Details about progamming in Haskell are presented in boxes throughout the text so they can be easily found and referred to.

we talked about the IO monad, but we intentionally kept the discussion narrowly focused on how to communicate with the outside world. We didn't discuss what a monad is. We've already seen in Chapter 7 that the IO monad is easy to work with. Notational differences aside, writing code in the IO monad isn't much different from coding in any other imperative language. When we had practical problems to solve in earlier chapters, we introduced structures that, as we will soon see, are actually monads. We aim to show you that a monad is often an obvious and useful tool to help solve a problem. We'll define a few monads in this chapter, to show how easy it is.
