This repository contains notes and exercise solutions related to "An Invitation to Applied Category Theory" by Fong and Spivak implemented in Haskell. I'm working through the softcover copy with ISBN 978-1-108-71182-1.
Most solutions live in src/ChapterX where X is the chatper number.
Tests for solutions live in test/ChatperXTests where X is the chapter number.
If a file doesn't exist in src for a chapter then the solution and tests are
contained in the same file (the solutions were not interesting enough to
define on their own, or the test was the solution itself).
It is assumed you have Stack installed.
You can build the project by running stack build, to validate that solutions
are passing all tests you can run stack test.
If you'd like to iterate on a solution or implement a new test, I like the following command for fast code/compile/test cycles:
stack build --fast --test --file-watch
