Template:ArticleVersion/help

{{av}} is a complex template - this is a reference guide explaining some important parts.

Structure

This template consists of 2 main parts: Variable definitions and a table (as well as documentation).

Variables

Variables are used to cut down on #ifexist - storing the result in a variable does not require multiple, identical invocations of an expensive parser function (also, it's a lot easier to read).

The variables defined in the template are list

• PAGE: The current page - uses the first parameter to av if specified, or defaults to {{PAGENAME}} (this is not implemented completely – you can specify a page name for av to use, but the colors are still determined by the namespace)
• Existence checks
  • e4, e3, e2, e1: These variables are set to 1 if the article exists in the corresponding namespace. The e stands for "exists".
    • Currently, DF2012=4, v0.31=3, 40d=2, and 23a=1. DF2012 is likely to change when the next version is released, so using the namespace as the variable name would make updating the template harder.
    • Note that this variable is blank when the page does not exist (this is for easy use with #if, which treats a blank string as false). If you need 0 to represent false, use {{#var:e4|0}} (this technique is used with eboth)
  • emw: 1 if the page exists in the Masterwork (mod) namespace
  • evan (Abbreviation of "exists in vanilla DF"): 1 if the page exists in any vanilla namespace
  • emod: 1 if the page exists in any mod namespace. This is currently redundant, since Masterwork is the only mod currently implemented. However, this should not be used when checking for a mod (don't resort to emw just because it works at the moment)
  • ismod: 1 if the current page is about a mod (not exactly related, but close enough)
  • eboth: 1 if the page exists in a vanilla and mod namespace
  • enone: 1 if the page does not exist in a vanilla or mod namespace (this is not the opposite of eboth - both are blank if the page exists in one set of namespaces but not the other)
