Description:

grid world

GridWorld #
GridWorld is a cellular automaton library associated with a rectangular grid.
It includes Conway's Game of Life evolution rules, and some classic
Conway patterns ready for injection.

Primary interfaces #
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.
final blinker = GridWorld.fromString('''
.....
..#..
..#..
..#..
.....
''');
copied to clipboard
where . means dead, and anything else means alive.


other worlds pasted into or appended to each other.


The cells have no builtin rules regarding their evolution.
For that, see Evolver.
Evolver #
A GridWorld accepts, via its takeStep method,
an Evolver.
An Evolver pushes a world forward in time
per some set of evolutionary rules.
A ConwayEvolver is an Evolver embodying Conway's
GOL rules with wrap-around boundary conditions.
This evolver also defines some static instances of
small GridWorlds containing famous Conway GOL
patterns, e.g. the Gosper glider gun:
static final gosperGliderGun = GridWorld.fromString('''
......................................
.........................#............
.......................#.#............
.............##......##............##.
............#...#....##............##.
.##........#.....#...##...............
.##........#...#.##....#.#............
...........#.....#.......#............
............#...#.....................
.............##.......................
......................................
''');

GridWorldIterable #
Extending Iterable<GridWorld>, this object combines a GridWorld and
an Evolver such that one may evolve a world in an iteration context, e.g.
for (var w in GridWorldIterable(initialWorld, limit: 1000)) {
render(w);
}

GridStringer #
A GridWorld 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.
