This handler creates and returns a "universe" script object initialised with given "seed" text and dimensions. For convenience, the seed text's visible characters can be anything, the set-up code itself replacing them with "■" characters. The use of the returned universe is demo'd later.

 

use framework "Foundation" -- For the regex at the top of newUniverse()

use scripting additions

return universe

 

In conjunction with the above, this fulfills the task as set:

 

-- Create a universe and start a list with its initial state.

set universe to newUniverse(seed, dimensions)

 

-- Return text containing the original and three generations of a "blinker" in a 3 x 3 grid.

Generation 3

 

This alternative to the task code runs an animation of a "Gosper glider gun" in TextEdit, the AppleScriptable text editor included with macOS. The animation's achieved by replacing the entire text of a document with successive universe states. It's faster than it sounds, but the universe size specified shouldn't be much greater than 150 x 150 with current machines.

==={{header|TI-83 BASIC}}===

This implementation is loosely based on the [http://www.processing.org/learning/topics/conway.html Processing Version]. It uses the home screen and draws cells as "X"s. It is extremely slow, and limited to a bounding box of 16 by 8. In order for it to work, you need to initialize arrays [A] and [B] to be 18x10.

:While 1

:For(X,2,9,1)

:[B]→[A]

:End

Here is an additional, very simple program to input the top corner of the GRAPH screen into the starting array. Make sure to draw on pixels in the rectangle (1,1) to (8,16).

:For(I,0,17,1)

:For(J,0,9,1)

Blinking example:

In Befunge-93, the maximum value for the width and height of the universe is 127, but there is an additional constraint of 4080 cells in total, so the largest universe would really be something like 120x34 or 68x60. Befunge-98 has no real limit on the size, although in practice a much larger universe will probably be unbearably slow.

Considering that the simplest implementation in C++ would lack any use of the object-oriented paradigm, this code was specifically written to demonstrate the various object-oriented features of C++. Thus, while it is somewhat verbose, it fully simulates Conway's Game of Life and is relatively simple to expand to feature different starting shapes.

Mathematica has cellular automaton functionality built in, so implementing Conway's Game of Life is a one-liner:

Example of a glyder progressing 8 steps and showing the 9 frames afterwards as grids of hashes and dots:

gives back:

Here is an example code, more simple (runs the game of life for N generations in a square of side S) :

G= round(rand(S));

surf(G); view([0 90]); pause(0.001)

The output can be either printed on Scilab's console, or on a graphic window.

This implementation has been developed using '''Cuis Smalltalk''' [https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev].

Here are different configurations:

"Blinker"

GameOfLife withAliveCells: { 4@2. 4@3. 4@4. 3@3. 4@3. 5@3 } ofSize: 10@10.

"Toad"

GameOfLife withAliveCells: { 2@4. 3@4. 4@4. 3@3. 4@3. 5@3 } ofSize: 10@10

This is the implementation:

Object subclass: #GameOfLife

instanceVariableNames: 'aliveCells boardSize'

numberOfAliveNeighborsOf: aCell

^aCell eightNeighbors count: [ :aNeighbor | self isAlive: aNeighbor ]
