lualife, v1.4

The library that implements Conway's Game of Life.

Supporting of field rotating.

Change Log

operations with fields as with matrices:
- rotating of a field clockwise.

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;
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.matrix.rotate():

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

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)
end

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

local rotated_field = matrix.rotate(field)
print_field(rotated_field)
