Documentation icon 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.

Given a page name and one or two revision IDs, you can construct links to several types of diffs.

Usage

{{Diff|page|diff|oldid|label|diffonly=yes}}
  • page – The title of the page.
  • diff – The ID or keyword that is used against the base ID. Possible keywords are:
    cur – compare with the current version of a page.
    prev – compare with the previous version of a page.
    next – compare with the next version of a page.
    id – This should be larger than oldid.
  • oldid – The base ID onto which the diff is generated.
  • label – Text to display as link. No label will give a numbered link.
  • |diffonly=yes – Displays the page comparisons only. Parameter name required.

All parameters other than page and diff are optional. Omitted parameters must be empty (by using a double pipe). You can also use the named parameters page, diff, oldid, and label.

Examples

Below each example in the left-hand column is the pseudocode for that example in brown italics and indented. Elements that should be entered literally are in brown bold underlined italics. When a parameter is left blank, the resulting two adjacent pipes are underlined (but not bolded): ||.

Code Output
{{Diff|Main Page|prev|204901573|Diff between a numbered version and the previous version}}
{{Diff|page|prev|oldid|label}}
Diff between a numbered version and the previous version

This is the form that would be used most often.

  • The diff= parameter (parameter number 2) should be the word prev.
  • The oldid= parameter (parameter number 3) should be the known revision number.
{{Diff|Main Page|204901573|202506579|Diff between two numbered versions of a page}}
{{Diff|page|diff|oldid|label}}
Diff between two numbered versions of a page
  • The page= parameter (parameter number 1) should be a name of a page, for instance Main Page.
  • The diff= parameter (parameter number 2) should be the larger revision number.
  • The oldid= parameter (parameter number 3) should be the smaller revision number.
{{Diff|Wikipedia:Pagediff|204934693|204901573|Diff between two numbered versions of a page in Wikipedia namespace}}
{{Diff|page|diff|oldid|label}}
Diff between two numbered versions of a page in Wikipedia namespace
  • The page= parameter (parameter number 1) should be a name of a page, for instance Wikipedia:Pagediff.
  • The diff= parameter (parameter number 2) should be the page revision to appear on the right (proposed change).
  • The oldid= parameter (parameter number 3) should be the page revision to appear on the left (original).
{{Diff|Main Page|next|204901573|Diff between a numbered version and the subsequent version}}
{{Diff|page|next|oldid|label}}
Diff between a numbered version and the subsequent version
  • The diff= parameter (parameter number 2) should be the word next.
  • The oldid= parameter (parameter number 3) should be the known revision number.
{{Diff|Main Page|cur|204901573|Diff between a numbered version and the current version of a page}}
{{Diff|page|cur|oldid|label}}
Diff between a numbered version and the current version of a page
  • The diff= parameter (parameter number 2) should be the word cur.
  • The oldid= parameter (parameter number 3) should be the known revision number.
{{Diff|Main Page|cur||Diff showing the most recent change to a page}}
{{Diff|page|cur||label}}
Diff showing the most recent change to a page
  • The diff= parameter (parameter number 2) should be the word cur.
  • The oldid= parameter (parameter number 3) should be empty.
{{Diff|Main Page||204901573|A link to a numbered version of a page}}
{{Diff|page||oldid|label}}
A link to a numbered version of a page
  • The diff= parameter (parameter number 2) should be empty.
  • The oldid= parameter (parameter number 3) should be the known revision number.
  • The result is not actually a diff, so this might be considered misuse of the template. See the {{oldid}} template.
{{Diff|Main Page|204901573|202506579|Comparison display without page display of two numbered versions of a page |diffonly=yes}}
{{Diff|page|diff|oldid|label|diffonly=yes}}
Comparison display without page display of two numbered versions of a page
  • The page= parameter (parameter number 1) should be a name of a page, for instance Main Page.
  • The diff= parameter (parameter number 2) should be the larger revision number.
  • The oldid= parameter (parameter number 3) should be the smaller revision number.
  • The diffonly= parameter, which must include the parameter name, can only be set to yes
