Template:!/doc
| 40px | This is a documentation subpage for Template:! (see that page for the template itself). It contains usage information, categories and other content that is not part of the original template page. |
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 {{!}}.
