Template:Diff2

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

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.

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).

(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.)

Examples

Code	Output
{{Diff2|123456789}}	[1]
{{Diff2|123456789|SomeUser's edit to "Some article name"}}	SomeUser's edit to "Some article name"
{{Diff2|123456789|External links|SomeUser's edit to "Some article name"}}	SomeUser's edit to "Some article name"
{{Diff2|123456789|External links|}}	[2]
