Template:Diff

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

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

Every historical version of a page has a revision ID, which you can find from the history of the page. 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 }}

• 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.

• oldid – The base ID onto which the diff is generated.
• label – Text to display as link. No label will give a numbered link.

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

Examples

Code	Output
{{diff|Main Page|204901573|202506579|Diff between two numbered versions of a page}}	Diff between two numbered versions of a 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 different pages}}	Diff between two numbered versions of different pages The page= parameter (parameter number 1) should be 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|prev|204901573|Diff between a numbered version and the previous version}}	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|next|204901573|Diff between a numbered version and the subsequent version}}	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 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 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}}	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.
