Real World Haskell

This easy-to-use, fast-moving tutorial introduces you to functional programming with Haskell. Learn how to use Haskell in a variety of practical ways, whether it's for short, script-like programs or large and demanding applications. Written for experienced programmers, Real World Haskell takes you through the basics of functional programming at a brisk pace, and 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 difference between procedural and functional programming
Learn about Haskell's compiler, interpreter, values, simple functions, and types
Find your way around Haskell's library -- and write your own
Use monads to express I/O operations and changes in state
Interact with databases, parse files and data, and handle errors
Discover how to use Haskell for systems programming
Learn concurrency and parallel programming with Haskell
You'll find plenty of hands-on exercises, along with examples of real Haskell programs that you can modify, compile, and run. If you've never used a functional language before, and want to understand why Haskell is now coming into its own as a practical language in so many major organizations, Real World Haskell is the place to start.
