Template:TOC
Template:Documentation subpage Template:High-risk
Usage
This is the Template:Tl 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 Template:Tl 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: Template:Quotation
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: Template:Quotation
