lualife, v1.5

The library that implements Conway's Game of Life.

Adding the placed field model that stores an offset and extending of possibilities of the simple field model.

Change Log

models:
- field:
  - supporting of checking if an other field fits inside;
- placed field:
  - extends the field model;
  - storing a field offset;
  - working with cells taking into account the field offset;
  - supporting of checking if an other field with offset fits inside;
  - supporting of copying the existing field with setting an offset.

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 checking if an other field fits inside;
  - supporting of mapping;
- placed field:
  - extends the field model;
  - storing a field offset;
  - working with cells taking into account the field offset;
  - supporting of checking if an other field with offset fits inside;
  - supporting of copying the existing field with setting an offset;
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;
operations with fields as with matrices:
- rotating of a field clockwise;
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 PlacedField = require("lualife.models.placed_field")
local sets = require("lualife.sets")

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

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

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

  io.write("\n")
end

local glider = PlacedField:new(Size:new(3, 3), Point:new(2, 2))
glider:set(Point:new(3, 2))
glider:set(Point:new(4, 3))
glider:set(Point:new(2, 4))
glider:set(Point:new(3, 4))
glider:set(Point:new(4, 4))

local blinker = PlacedField:new(Size:new(3, 3), Point:new(1, 2))
blinker:set(Point:new(2, 2))
blinker:set(Point:new(2, 3))
blinker:set(Point:new(2, 4))

local unioned_field = sets.union(glider, blinker)
print_field(unioned_field)

local complemented_field = sets.complement(glider, blinker)
print_field(complemented_field)

local intersected_field = sets.intersection(glider, blinker)
print_field(intersected_field)
