[edit] [purge] Template documentation

This template is used on 4,000,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes should first be tested in this template's /sandbox or /testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this template. Please consider discussing any changes on the talk page before implementing them.

Usage

This is the {{!}} meta-template.

This is an auxiliary template allowing the encoding of "|" within template parameters. It is necessary if the character is used in wiki table syntax, or if the parameter is automatically wikilinked and you wish to use a pipe to specify different link text from the target page name. In other cases it is better to use "|".

This template cannot be used for putting the character as text in a wiki table; in that case, again, "|" can be used.

Note that no special template is needed for "!" (exclamation mark).

This is a high risk template, and it usually cannot be substituted (see conditions for substing on the section below).

Substitution

It is possible to substitute {{!}} only if an unescaped "|" works as expected, i.e. after substituting the template containing {{!}}, or after eliminating an #if containing {{!}}.
