Get Programming with Haskell

Lesson 37. Capstone: Building a prime-number library

This capstone covers

• Building a new project by using stack
• Writing basic library functions for working with prime numbers
• Using stack test and QuickCheck to check for bugs as you go
• Refactoring code to fix errors
• Adding new functions and tests to your project as you go

So far in this unit, you’ve focused on one problem: creating a program for working with palindromes. For this capstone, you’ll be reiterating over all the work you’ve done creating modules and learning about stack with a new problem. This time you’ll be working on creating a library to work with prime numbers. You’ll focus on three essential problems:

• Listing out primes less than a specified number
• Determining whether ...
