LifeViewer is a browser-based scriptable pattern viewer and editor used to simulate Life and a wide range of other 1D and 2D cellular automata.
If you want to use LifeViewer on your own site then the latest release can be downloaded here.

Rule support
LifeViewer supports the following rule families:
Built-in Rules

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.

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 for 2-state and Generations patterns. Some Themes also specify whether major grid lines are used and if so on what interval.
Themes are primarily used to 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.
Grid
Some Themes define specific GridLine colours for standard and Major GridLines and also the major GridLine interval.
GRID: grid line colour
GRIDMAJOR: major grid line colour and interval
Two-state Themes
For two-state Themes there are five colours that are used for defining the cell colours:
| Key | Description |
| BACKGROUND | cell never occupied |
| ALIVE | cell just born |
| ALIVERAMP | cell alive for at least AGESTATES generations (default 63) |
| DEAD | cell just died |
| DEADRAMP | cell dead for at least HISTORYSTATES generations (default 63) |
New cells are drawn in the ALIVE colour.
If cells stay alive they fade from the ALIVE colour to the ALIVERAMP colour over the next AGESTATES (default 63) generations. This provides a visual representation of cell longevity.
Cells are drawn in the DEAD colour when they die.
If they stay dead they fade from the DEAD colour to the DEADRAMP colour over the next HISTORYSTATES (default 63) generations. This provides a visual representation of cell history.
Click on "Expand" to the right to see the definitions of the available two-state Themes.

Multi-state Themes
Multi-state Themes are used for Generations rules and there are six colours that are used for defining the cell colours:
| Key | Description |
| BACKGROUND | cell never occupied |
| ALIVE | cell alive |
| DYING | cell just started dying |
| DYINGRAMP | cell about to die |
| DEAD | cell just died |
| DEADRAMP | cell dead for at least HISTORYSTATES generations (default 63) |
New cells are drawn in the ALIVE colour.
Cells are drawn in the DYING colour when they start to die. They then fade to the DYINGRAMP colour over the number of generations defined in the rule.
Once cells reach the DYINGRAMP colour then on the next generation they die and become the DEAD colour.
If they stay dead they fade from the DEAD colour to the DEADRAMP colour over the next HISTORYSTATES (default 63) generations. This provides a visual representation of cell history.

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 which means you can add them to any pattern file and other pattern readers will happily ignore them. The should be encloded in [[ and ]]. All commands must be surrounded by whitespace. Multiple script sections are allowed.
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:

Waypoints
These commands allow you to setup a list of Waypoints for the camera to follow during playback. For each waypoint you can specify a camera position (with a subset of the Camera commands), playback speed (with a subset of the Playback commands) and then a target generation by which you want the camera to reach that position.
Click on "Expand" to the right to view the Waypoint commands.
