Template:Deprecated template/sandbox

Template documentation[view] [edit] [history] [purge]

The {{Deprecated template}} template notifies users that a given template has been superseded or replaced by another template, or has simply been deprecated (i.e., advised to no longer be used) without a direct replacement. It is useful when a redirect is ineffective due to usage differences, or when reducing the number of redirects is desired to simplify bot parsing.

If the template is fully deprecated, the deprecated template’s content should be fully replaced/overridden by the message from {{Deprecated template}}, ensuring that anyone using the template will only see the notification, and not invoke the deprecated template.

Usage

Templates not fully deprecated

If the deprecated template is not yet ready for full deprecation since it is still in use (transcluded) on pages, add <noinclude>...</noinclude> tags around the {{Deprecated template}} template in the source code of the deprecated template. This ensures that the deprecation notice appears only on the template’s documentation page and not on every page where the template is transcluded.

Fully deprecated templates

Once a template has been fully deprecated and is no longer transcluded on any pages, you can remove the <noinclude>...</noinclude> tags surrounding the {{Deprecated template}} in the deprecated template’s source code. This will display the deprecation notice on any pages still using the deprecated template.

Afterward, consider nominating the template for deletion through Wikipedia:Templates for discussion or marking it with {{Historical template}} to indicate its deprecated status.

Note that deprecated stub templates are not normally deleted, as they are used as soft redirects. These should be marked with {{Deprecated stub}}.

{{Deprecated template|old template name|new template name}}

Usage without a second (replacement) template name simply produces:

Parameters

Standard

{{Deprecated template|Old|New}}

Additional

The template can show parameters as follows:

{{Deprecated template|Old|New|parameter}}

{{Deprecated template|Old|New|<nowiki>parameter=foo</nowiki>}}

The template can also show a note:

{{Deprecated template|Old|New|note=Further details can be inserted here}}

The |note= parameter can also be given as |reason= or |result=.

Special parameters for templates outside template namespace.

|old= and |new= can be used with the full names including namespace.

{{Deprecated template|old=Template:Old|new=Wikipedia:New}}

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.

Category suppression

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).
