Learning Haskell with Chess

Exercise 1

Learning Targets

• recapitulate Haskell types (keywords type and data, product and sum types)
• Helium: define equality functions (pattern matching)
• pretty printing

Tasks

• Define data types that represent boards, squares, positions, pieces and game states.
• Helium: Implement suited eq-functions.
• Implement a function prettyBoard, that transforms a board into a clearly arranged string representation (human readable :-)). Support this function with auxiliary functions that pretty print pieces, squares, ...
