Usage

This is the {{!}} meta-template. Its use is analogous to an escape character. This is an auxiliary template allowing the encoding of "|" within template parameters, because the pipe character is normally interpreted as a separator. This template 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 {{!}}.

A simple example

The following template code for {{Quotation}} using an ordinary pipe character,

  • {{Quotation|It is not possible to use an ordinary pipe character | in template parameters, as it will be interpreted as a separator.|[[Help:Template#Usage hints and workarounds]]}}

produces:

It is not possible to use an ordinary pipe character

in template parameters, as it will be interpreted as a separator., Help:Template#Usage hints and workarounds

whereas this code using the {{!}} meta-template,

  • {{Quotation|It is not possible to use an ordinary pipe character {{!}} in template parameters, as it will be interpreted as a separator.|[[Help:Template#Usage hints and workarounds]]}}

produces:

It is not possible to use an ordinary pipe character | in template parameters, as it will be interpreted as a separator.
