LifeWiki:LifeViewer cheatsheet for LifeWiki articles

This page aims to be an incomplete collection of example LifeViewer configuration scripts which can be used on LifeWiki for different kinds of patterns.

This is not an authoritative list. There may be LifeViewer configurations that are not listed here but are frequently used.

This page assumes that the viewer is shown outside the infobox. (See also this thread for infobox-related questions.)
