Repository Rules

LifeViewer can load rules from the Rule: namespace here on LifeWiki. The rules must be in RuleTable format. LifeViewer supports both @TABLE and @TREE format rules. Typically @TREE rules run much faster so if possible ensure there is an @TREE version of the rule before the @TABLE version (if present). LifeViewer supports the @COLORS section and the @NAMES section but does not support the @ICONS section (which will be ignored if present), although this may be supported in future.[1]

Aliases

LifeViewer contains a large list of alias names for particular rules. This list of rule name aliases can be found by clicking the Aliases button under Help.

Grid and neighbourhood support

LifeViewer supports many different neighbourhoods on square, hexagonal or triangular grids.

Click on "Expand" to the right to view the full list of supported neighbournoods per grid type.

Bounded grid types

LifeViewer supports patterns on "unbounded" grids (maximum 16384x16384 in size) and the following bounded grid types:

  • Plane
  • Cylinder (with optional shift)
  • Torus (with optional shift)
  • Klein-bottle (with optional shift)
  • Cross-surface
  • Sphere

For range 2+ neighbourhoods only Plane, and Torus (without shift) are supported.

Native support for BSFKL, Extended Generations and deficient rules is also planned.[2][3][4] Support for 1D totalistic rules and multiple neighbourhoods rules may also be planned.[5][6]

Themes

Themes are used to define the colours of cells, the background and the grid lines. Some Themes also specify whether major grid lines are used and if so on what interval. Most Themes provide a visual representation of cell history and longevity.

The default Theme is "Blues" but this can be changed by clicking Theme in the Settings menu or with the THEME script command.

x=3, y = 3, rule = Life 3o$2bo$bo! [[ AUTOSTART THUMBNAIL GRID STOP 128 ZOOM 8 X 32 Y -31 HEIGHT 560 ]]

Scripts

LifeViewer supports a large number of script commands than can be used to control playback, the camera, labels and annotations, colours and many other aspects.

Scripts must be embedded in pattern comments. Commands must be surrounded by whitespace.

For example loading the following pattern into LifeViewer will start playback automatically (AUTOSTART) and then stop at generation 30 (STOP 30).

 #C [[ AUTOSTART STOP 30 ]]
 x = 3, y = 3, rule = Life
 o$
 obo$
 2o!
 

It's also valid to have script commands after the RLE since this area is treated as comments.

 x = 3, y = 3, rule = Life
 o$
 obo$
 2o!
 [[
   ANGLE 30
   GPS 5
   AUTOSTART
   THEME Fire
 ]]
 

Only text surrounded by [[ and ]] is interpreted as script commands.

 #C An example [[ ZOOM 16 ]] with camera settings [[ X -4 Y 5 ]]
 #C and [[ GRID ]] grid lines.
 x = 3, y = 3, rule = Life
 o$
 obo$
 2o!
 

Below is a list of script commands by category:
