Chapter4. IO in Haskell

Chapter4. I/O in Haskell

Goals

After completing this chapter four, you'll be able to:

• Understand how Haskell handles I/O by using IO types
• Use do-notation to perform I/O(Understanding of the underlying monad theory is not necessary to program using the I/O system)
• Write pure programs that interact with the real world
• Access command-line arguments
• Use the traditional approach to interacting through I/O
• Write I/O code using lazy evaluation to make I/O easier
• Work with file handles in Haskell
• Read from and write to files
