Template:Linkexist/doc
 | This is a documentation subpage for Template:Linkexist. It may contain usage information, categories and other content that is not part of the original template page. |
NOTE: This template has confusing behaviour, poor incomplete documentation, and produces invalid wikitext in some cases.
The template is a way of creating optional links based on whether the target exists or not.
It is presently used in {{culture of region}}, as that template uses the logic in question so many times that transcluding it every time would lead to cluttered code.
Usage
<syntaxhighlight lang="wikitext"> linktext </syntaxhighlight>
If alternative is specified, the template will link to that title. Otherwise, the template will link to page if it exists. linktext, if specified, will be the label for the link (or unlinked output).
Examples
<syntaxhighlight lang="wikitext">[[History of Ghana|]]</syntaxhighlight>
[[History of Ghana|]]
<syntaxhighlight lang="wikitext">History</syntaxhighlight>
<syntaxhighlight lang="wikitext">History</syntaxhighlight>
