About the course

This is an online course on Functional Programming that uses the Haskell programming language. You can study at your own pace. All the material and exercises are openly available.

The course is inteded to be followed through the Course page, but in case the course page is down or you want an offline backup, the course material is also available in this repository (part1.html, part2.html).

Exercises

Exercises can be found under exercises/ directory. All required dependencies can be downloaded and built with:

stack build

Exercises are Haskell source code files named Set1.hs, Set2.hs and so on. You complete the exercises by editing the file according to the instructions in the file. You can check your answers by running

stack runhaskell SetXTest.hs

in the exercises/ directory. Remember to replace X with the number of the set you are working on.

See the material for more info.

Troubleshooting

Here are some fixes for common problems with stack build:

• If you get an error like While building package zlib-0.6.2.3, you need to install the zlib library headers. The right command for Ubuntu is sudo apt install zlib1g-dev.
• If you get an error like Downloading lts-18.18 build plan ... RedownloadInvalidResponse, your version of stack is too old. Run stack upgrade to get a newer one.
