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 intended 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 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.
Here are some fixes for common problems with stack build:
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.Downloading lts-18.18 build plan ... RedownloadInvalidResponse, your version of stack is too old. Run stack upgrade to get a newer one.If you need to use a newer version of GHC, perhaps to get
vscode-haskell to work, try the ghc-9.6.6 branch of this repository
for GHC 9.6.6. The default for the course is GHC 9.2.8 for now.
Don’t forget to run stack build again after changing branches.
