title Beginning Practical Haskell

An introductory Haskell programming course by Richard Cook

This course will build up enough knowledge and understanding of the Haskell programming language to tackle a real-world problem—something not difficult but not completely trivial. The problem I've chosen is one that I've often tackled, specifically web scraping: pulling web pages off the Internet and extract and manipulating numerical and textual data.

I wrote the original web scraper in Python in about two hours. The Haskell version took a wee while longer, clocking it at around eight, but is superior in nearly every respect.

Overview

  • Will teach the essentials required to write real programs in Haskell
  • Will only dig into mathematical underpinnings as needed to understand real-world programming problems
  • Will enable the student to use the tools needed to build real programs and consume Haskell libraries from third parties
  • Intend to complement other courses offered by Seattle Area Haskell Users' Group

Prerequisites

  • This course will use Stack
  • The examples have been tested on recent versions of Windows, Mac OS X, Ubuntu and Centos operating systems
  • Please follow setup instructions to install Stack
  • Make sure the following example based on the setup guide works:
stack new hello-world simple --resolver=lts-7.8
cd hello-world
stack setup
stack build
stack exec hello-world

If everything is working as expected, the last line should yield the output hello world.
