Real World Haskell pdf epub mobi txt 電子書 下載2025

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.

Bryan O'Sullivan is an Irish hacker and writer who likes distributed systems, open source software, and programming languages. He was a member of the initial design team for the Jini network service architecture (subsequently open sourced as Apache River). He has made significant contributions to, and written a book about, the popular Mercurial revision control system. He lives in San Francisco with his wife and sons. Whenever he can, he runs off to climb rocks.

Don Stewart is an Australian hacker, currently completing his computer science doctorate at the University of New South Wales, Sydney. Don has been involved in a diverse range of Haskell projects, including practical libraries such as Data.ByteString and Data.Binary, as well applying the Haskell philosophy to real world applications, including compilers, linkers, text editors, network servers and systems software. His recent work has focused on optimising Haskell for high-performance scenarios, using techniques from term rewriting. He is the current editor of the Haskell Weekly News.

John Goerzen is an American hacker and author. He has written a number of real-world Haskell libraries and applications, including the HDBC database interface, the ConfigFile configuration file interface, a podcast downloader, and various other libraries relating to networks, parsing, logging, and POSIX code. John has been a developer for the Debian GNU/Linux operating system project for over 10 years and maintains numerous Haskell libraries and code for Debian. He also served as President of Software in the Public Interest, Inc., the legal parent organization of Debian. John lives in rural Kansas with his wife and son, where he enjoys photography and geocaching.
