This is the documentation page of the template Diff2.

This template is intended to be useful for creating links to "diffs"; that is, links to pages that show the differences between two versions of a wiki page.

Every version of a page has a revision ID, which you can find from the history of the page by looking at the link for the timestamp, which is of the form:

http[s]://en.wikipedia.org/w/index.php?title=SomePageName&oldid=442212827

The number after oldid= is the revision ID.

Unlike {{Diff}}, this template does not require the page name, and provides a diff between a specified revision ID and the one immediately before it (i.e. what changed at a certain ID).

Usage

{{Diff2 |oldid [|section] [|label]}}
  • oldid – The base ID onto which the diff is generated.
  • section – (optional) The section (anchor) within the page.
  • label – (optional) Text to display as link. No label will give a numbered link.

If 3 parameters are specified (i.e. parameter {{{3}}} exists), parameter {{{2}}} is the section, and parameter {{{3}}} is the label. Otherwise, parameter {{{2}}}, if present, is the label (and the link is to the whole page)

Note that if you put a space after the numerical id, it malfunctions. Compare:
