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.
