Repositories with solutions to the exercises in the Haskell Book (i.e. Haskell Programming from first principles)

Each repo is added as a git submodule, and each directory leads to the solutions repo of the given contributor. Entries that are not shown as links are hosted on platforms other than Github (e.g., Gitlab), and links to those should be part of the last commit message (see ptrfrncsmrph for example).

Cloning this repo WITH submodules

Stackoverflow questions 1 and 2 are very helpful, but the gist is:

• clone all repos:
  git clone --recurse-submodules https://github.com/sac-fp/HaskellBook-solutions.git

• clone specific repo(s):
  git clone --recurse-submodules=ptrfrncsmrph --recurse-submodules=txels https://github.com/sac-fp/HaskellBook-solutions.git

See more at section --recurse-submodules in git help clone.

3. git submodule add <url-of-your-repo> <your-github-username>
4. Stage and commit your changes
5. git push origin add-solution
6. Create a pull request
