Grid World

A dart implementation of Conway's Game of Life.

GridWorld is an NxM 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.

A GridWorld accepts an Evolver to evolve it forward in time. A ConwayEvolver is an Evolver embodying Conway's game of life rules.

This evolver defines some small worlds containing famous GOL patterns, e.g. the Gosper glider gun:

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

These small worlds can be rotated, flipped and combined to build larger worlds using GridWorld methods.

A world can be converted to various strings using GridStringer helper classes.

The GridStringerAnsi class converts a world to a string with embedded ANSI escape sequences that can be used to create an animation on a terminal.
