Template:Diff2/doc

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



 * 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 exists), parameter  is the section, and parameter  is the label. Otherwise, parameter, if present, is the label (and the link is to the whole page).

(Consequently, specifying a section but no label can be achieved by leaving the label blank save for its pipe character, as in the fourth example below.)
