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 {{!}}.

• {{pipe}} - Note that this one looks like {{{{#if:!|!| tlf|...}}{{#ifeq:x|| |{{{2}}} | }}{{#ifeq:x|| |{{{3}}} | }}{{#ifeq:x|| |{{{4}}} | }}{{#ifeq:x|| |{{{5}}} | }}{{#ifeq:x|| |{{{6}}} | }}{{#ifeq:x|| |{{{7}}} | }}{{#ifeq:x|| |{{{8}}} | }}{{#ifeq:x|| |{{{9}}} | }}}} but has a very different meaning for the MediaWiki parser and thus has different functionality.
