Examples for "Haskell Tutorial and Cookbook" by Mark Watson

This repo contains the examples for my Haskell book that I try to update with new material about once a year:

Haskell Tutorial and Cookbook

If you would like to support my work please consider purchasing my books on Leanpub and star my git repositories that you find useful on GitHub. You can also interact with me on social media on Mastodon and Twitter.

I am starting to use this repo for all personal Haskell projects.

In the future, if you see a file named NOT_YET_IN_BOOK.md in any subdirectory, then please don't expect (yet) that this example is in the book. Currently everything in this repo is in the second edition of my book.

Updates

Updated 7/28/2023 for stack resolver: lts-lts-21.4

Note: to build sqlite example I had to:

Set 'allow-newer: true' in /home/markw/.stack/config.yaml to ignore all version constraints

Tool Installation

See Appendix A in my book, or simply install stack and hlint.

Note: 6/18/2020: install directions in Appendix A to optionally install cabal-install (with latest GHC 8.8.3) produces an error running:

    stack install cabal-install

Installing cabal-install is optional. Installing stack using the directions in Appendix A which refers you to th official documentation at [http://docs.haskellstack.org/en/stable/README.html](http://docs.haskellstack.org/en/stable/README.html is sufficient for running the exampes in my book.
