Usage[edit]

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 "&#124;".

This template cannot be used for putting the character as text in a wiki table; in that case, again, "&#124;" 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 in the section below).

Substitution[edit]

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 {{!}}.
