GridWorld

A set of dart classes for playing with Conway's Game of Life at the command line.

git clone [e-mail]:monopole/grid_world.git
dart grid_world/example/main.dart

There are three primary interfaces: GridWorld, Evolver and GridStringer.

GridWorld

A GridWorld is a grid of cells that can be dead or alive. A GridWorld can be constructed from

• a multi-line string, e.g.

  .....
  ..#..
  ..#..
  ..#..
  .....
  

  where . means dead, and anything else means alive.

• other worlds pasted into or appended to each other.

Evolver

A GridWorld accepts an Evolver to evolve it forward in time.

A ConwayEvolver is an Evolver embodying Conway's GOL rules with wrap-around boundary conditions. This evolver defines some small worlds containing famous GOL patterns, e.g. the Gosper glider gun:

static final gosperGliderGun = GridWorld.fromString('''
......................................
.........................#............
.......................#.#............
.............##......##............##.
............#...#....##............##.
.##........#.....#...##...............
.##........#...#.##....#.#............
...........#.....#.......#............
............#...#.....................
.............##.......................
......................................
''');

GridStringer

A world can be converted to a string using a GridStringer.

GridStringerAnsi is a GridStringer that converts a world to a string with embedded ANSI escape sequences for animation on a terminal.
