 | Template:Deprecated templateisdeprecated. Please use [[Template:{{{2}}}]] instead. |
The {{Deprecated template}} template notifies users that a given template has been replaced by a different one or ones, or simply deprecated (advised to no longer be used) without a replacement. This is useful when usage is different (so a redirect won't work) or you'd like to reduce the number of redirects (which makes bot parsing more difficult).
Whenever possible, it should replace the deprecated template's content entirely, so that someone using the template will see only the message.
{{Deprecated template|old template name|new template name}}
Usage without a second (replacement) template name simply produces:
| Template:Deprecated templateisdeprecated. |
The template changes style depending on what kind of page it is shown on. Thus it adheres to the standardised looks for the different namespaces.
If a deprecated template is still in use on other pages, add <noinclude>...</noinclude> tags around the {{Deprecated template}} template. That way the template page will show the deprecation tag, but pages using it will not. If a template has been fully deprecated, meaning that it not in use on other pages, the noinclude tags may be removed. That way a deprecation tag will show on any page using the deprecated template. Afterwards consider nominating the template for deletion, or marking it with {{Historical template}}.
{{Deprecated template|Old|New}}
| Template:Oldisdeprecated. Please use Template:New instead. |
The template can show parameters as follows:
{{Deprecated template|Old|New|parameter}}
{{Deprecated template|Old|New|<nowiki>parameter=foo</nowiki>}}
| Template:Oldisdeprecated. Please use {{New|parameter}} instead. |
| Template:Oldisdeprecated. Please use {{New|parameter=foo}} instead. |
The template can also show a note:
{{Deprecated template|Old|New|note=Further details can be inserted here}}
| Template:Oldisdeprecated. Please use Template:New instead. Further details can be inserted here, such as why the template is retained, or the particulars of the replacement process |
The |note= parameter can also be given as |reason=or|result=.
|old= and |new= can be used with the full names including namespace.
{{Deprecated template|old=Template:Old|new=Wikipedia:New}}
| Template:Oldisdeprecated. Please see Wikipedia:New instead. |
To link to a category full of templates, use :Category:Name of category here, with a leading colon.
The |new= parameter cannot be used with the third unnamed parameter (the one illustrating a parameter of the third template). For example, this is not valid:
{{Deprecated template|Old|new=User:SnorkelWeasel/MyTemplate|<nowiki>chickens=yes</nowiki>}}
Such a feature could be added, but it has never been needed yet.
The template can be prevented from categorizing by adding |nocat=true. This is only intended for examples, e.g. in the template's own documentation. In that case, not only the page itself will not be categorized, but transclusions of such pages will also be prevented from categorizing in Category:Pages using deprecated templates. Do not use this parameter to passive-aggressively contest a template's documentation. Take up the matter on the template's talk page or that of a relevant other venue, such as WP:Village pump (technical).
<del> element, and can be used in articles, e.g. about HTML or other specifications that may have deprecated features)
