How I Learned Haskell by Writing Tiny Games
summary
Builds a series of tiny roguelike games in Haskell, often shipping one-game-per-day while traveling, to learn practical Haskell techniques. Uses GHC with getContents and lazy evaluation to fold user input into game states, isolates IO and randomness so core logic stays pure, structures code with modules, record types and typeclasses, and gets fast feedback with doctest and Hoogle. Examples include an insta-death one-tile roguelike, Robot Finds Kitten clones, and a 10x10 Orc-and-Pie prototype that runs and is playable.
