Template:Deleted template
Template documentation{{Deleted template}} provides a way to delete templates but still retain them for the purpose of correctly displaying old revisions of pages. When using this method to delete a template, all existing transclusions should be removed in the usual way, and {{Deleted template}} added into the template being deleted. This should ensure correct display in old revisions, and a warning when used in a revision postdating the deletion.
Current revisions containing templates deleted in this way (as well as the deleted templates themselves) are automatically categorised in Category:Pages containing deleted templates.
Usage
The template takes 3 compulsory parameters:
- the revision ID of the template at the time of it being deleted. Due to phab:T235957, this parameter is no longer used, and the third parameter (date) is used to decide whether to treat the page like an old revision.
- template name
- date the template was deleted
To use this template, add it at the beginning of the template to be deleted, adding the closing brackets of {{Deleted template}} at the end:
Example:
{{Deleted template|388523941|Example|12 February 2011|
Old template
did various things
and possibly other things
}}
- There is also one optional parameter: the
|extra=parameter may be used to add further information at the end of the message.
Template documentation
Associated template documentation may be worth retaining, for example for references to alternative templates.
- Use {{hat}}/{{hab}} to collapse usage instructions which are no longer relevant
- Remove any categories (possibly convert them to See Also links)
- Add a {{historical}} template as in this example for {{expand}}:
{{Historical|category=no|brief=yes|comment=This template was [[Template:Deleted template|deprecated]] following deletion discussion archived at [[Wikipedia:Templates_for_discussion/Log/2010_December_16#Template:Expand]]}} - If used with {{Ambox}} which has the
|name=parameter present for the|subst=parameter,|doc=nomust also be passed to {{Ambox}} and <noinclude>{{documentation}}</noinclude> manually placed at the end of the template code.
