lualife, v1.3

The library that implements Conway's Game of Life.

Supporting complement and intersection of fields as sets and extending of possibilities of size and field models.

Change Log

• models:
  • size:
    • supporting of checking if an other size with offset fits inside;
  • field:
    • supporting of counting of set cells;
• operations with fields as with sets:
  • complement of fields:
    • supporting an offset for the second operand;
  • intersection of fields:
    • supporting an offset for the second operand.

Features

• models:
  • size:
    • supporting of checking if an other size with offset fits inside;
  • point:
    • supporting of translation;
    • supporting of scaling;
    • supporting of textual representation;
  • field:
    • storing only of set cells;
    • supporting of counting of set cells;
    • supporting of checking if a cell is set;
    • supporting of mapping;
• generating of a random field:
  • customizable filling factor;
  • limiting by a cell count:
    • lower limit;
    • upper limit;
• operations with fields as with sets:
  • union of fields:
    • supporting an offset for the second operand;
    • restricting of the result size by the size of the first operand;
  • complement of fields:
    • supporting an offset for the second operand;
  • intersection of fields:
    • supporting an offset for the second operand;
• populating of a field according to Conway's Game of Life rules:
  • using of the naive algorithm with iterating and copying of a whole field.

Examples

lualife.sets:

local Size = require("lualife.models.size")
local Point = require("lualife.models.point")
local Field = require("lualife.models.field")
local sets = require("lualife.sets")

local function print_field(field)
  assert(field:isInstanceOf(Field))

  field:map(function(point, contains)
    io.write(contains and "O" or ".")

    if point.x == field.size.width - 1 then
      io.write("\n")
    end
  end)

  io.write("\n")
end

local glider = Field:new(Size:new(3, 3))
glider:set(Point:new(1, 0))
glider:set(Point:new(2, 1))
glider:set(Point:new(0, 2))
glider:set(Point:new(1, 2))
glider:set(Point:new(2, 2))

local blinker = Field:new(Size:new(3, 3))
blinker:set(Point:new(1, 0))
blinker:set(Point:new(1, 1))
blinker:set(Point:new(1, 2))

local unioned_field = sets.union(glider, blinker, Point:new(-1, 0))
print_field(unioned_field)

local complemented_field = sets.complement(glider, blinker, Point:new(-1, 0))
print_field(complemented_field)

local intersected_field = sets.intersection(glider, blinker, Point:new(-1, 0))
print_field(intersected_field)
