Product Description

This easy-to-use, fast-moving tutorial introduces you to functional programming with Haskell. You'll learn how to use Haskell in a variety of practical ways, from short scripts to large and demanding applications. Real World Haskell takes you through the basics of functional programming at a brisk pace, and then helps you increase your understanding of Haskell in real-world issues like I/O, performance, dealing with data, concurrency, and more as you move through each chapter. With this book, you will:

• Understand the differences between procedural and functional programming
  
• Learn the features of Haskell, and how to use it to develop useful programs
  
• Interact with filesystems, databases, and network services
  
• Write solid code with automated tests, code coverage, and error handling
  
• Harness the power of multicore systems via concurrent and parallel programming

You'll find plenty of hands-on exercises, along with examples of real Haskell programs that you can modify, compile, and run. Whether or not you've used a functional language before, if you want to understand why Haskell is coming into its own as a practical language in so many major organizations, Real World Haskell is the best place to start.

The best book on Haskell to come along in a long time
Until this book came along you really needed two books to learn Haskell Programming. Haskell: The Craft of Functional Programming (2nd Edition) (International Computer Science Series) teaches the mechanics of Haskell programming, but it can be dry reading. The Haskell School of Expression: Learning Functional Programming through Multimedia shows you the possibilities of Haskell via multimedia programming, but it does miss some basic details about the language that are in the first book. This second book is lots of fun, but I think that the new O'Reilly book replaces the first book entirely and some of the functionality of the second.

Haskell has its roots in academia, and functional programming requires lots of up-front thinking about your total approach. It is not a language where you can usually just sit down and start coding. This book shows you how to use functional programming and Haskell to solve real-world problems. Each chapter contains many code samples, and many contain complete applications. The book contains an application that downloads podcast episodes from the web and stores the history in an SQL database. There is also an application that takes a grainy phone camera photo of the barcode on a book and transforms it into an identifier that you can then ue to query a library website. This is the "fun stuff" that seems to work out so well and so elegantly in the Haskell language.

It is not necessary that you have any prior knowledge of Haskell or functional programming concepts, however general programming concepts are a requirement. This is certainly the first Haskell book to come along in a few years that I would recommend for the novice. As usual with the best of O'Reilly's programming books, this one is well illustrated with lots of well-commented code. The following is the table of contents:

Excellent
Still reading through it now.

The text is incredibly readable and straightforward. It's set up for those who already know how to program imperatively (e.g. C++/Java/C, etc), and takes those readers deep into Haskell & functional programming.

Covers important topics for new functional programmers, including performance analysis, testing, debugging, and optimization.

A timely cornucopia of Haskell knowledge
This is a really good book to add to any Haskell programmer's bookshelf. It's also a really good book to help folks get started with Haskell programming if they've ever wanted to journey into the realm of functional programming.

The book covers a lot of topics and some areas I hadn't really thought of using Haskell for (barcode recognition).

Also it's the only Haskell book I know to cover some of the features of GHC (Glasgow Haskell Compiler) and optimization using the tools that come with it.
