Conway

A quick cli conway's game of life implementation in Haskell using Representable and Comonad.

The board 'wraps around' Pac-man style.

Running

  • Clone the repo: git clone https://github.com/ChrisPenner/conway.git
  • stack build && stack exec conway-exe
  • ???
  • Profit!

Customization

  • Clone the repo: git clone https://github.com/ChrisPenner/conway.git
  • Define your own shapes as a list of Coordinates; e.g.
glider, blinker, beacon :: [Coord]
glider = [(1, 0), (2, 1), (0, 2), (1, 2), (2, 2)]
blinker = [(0, 0), (1, 0), (2, 0)]
beacon = [(0, 0), (1, 0), (0, 1), (3, 2), (2, 3), (3, 3)]
  • Define your own 'life' rules as a function from Grid -> Bool; the grid passed to the function is focused on the cell you should compute 'life' for.
  • Customize your tick time in Main.hs
  • Build a starting grid using provided combinators, e.g.
grid :: Grid
grid = mkGrid $
     glider `at` (0, 0)
  ++ blinker `at` (5, 10)
  ++ beacon `at` (15, 5)
