Game of Life

Ruby solution to John Conway's 'Life' celullar automaton.

Rules of life

1. Any live cell with <2 live neighbours perishes.
2. Any live cell with 2 || 3 live neighbours lives.
3. Any live cell with >3 live neighbours perishes.
4. Any dead cell with == 3 live neighbours comes alive.

Local usage

require and specify

>$ irb

  2.7.0 :001 > require './path_to_file/pattern.rb'
  2.7.0 :002 > require './path_to_file/board.rb'
  2.7.0 :003 > require './path_to_file/cell.rb'
  2.7.0 :004 > require './path_to_file/game.rb'

  2.7.0 :005 > game = Game.new

set start pattern loaf, toad and test are valid

>$
  2.7.0 :006 > game.condition('test')

run with period n

>$
  2.7.0 :007 > game.start(n)

Testing

Using rspec and simplecov for coverage

>$ rspec

User Stories

As a Developer,
To pay homage to the late Conway,
I would like to recreate the Game of Life.

As a Cell,
To be able to exist in my world,
I can detect the state of cells around me.

As a User,
To be able to interact with the game,
I can choose my starting conditions.

As a Cell,
To be able to grow,
I switch off if I have 3 live neighbours.

As a Cell,
To be able to perish,
I would like to switch off If I have more than 3; or less than 2 neighbours.

In the works

As a User,
So I can experiment,
I would like to upload grid configurations to the application.

As a User,
To be able to see the game,
I would like to visualise results in a command line interface.
