Description

Template:Diff/doc 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 historical version of a page has a revision ID, which you can find from a given page's revision history. With a page name, and one or two revision IDs, you can construct links to several types of diffs.

Syntax

{{ diff page | diff | oldid | label }}
Optional parameters
|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.


18px Note:  All parameters are optional. Omitted parameters must be shown as empty by using a double pipe. You can also use the named variables (|page= |diff= |oldid= and |label=), with no contents following.

Examples

Code Output
{{diff|Main Page|8130|4111|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|Main Page|prev|4111|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|4111|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|4111|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||4111|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.
{{diff|(no page)|8130|4111|Diff between two numbered versions of a page}} Diff between two numbered versions of a page
  • The page= parameter (parameter number 1) can be left blank.
  • 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|Main Page|8130|4111|(no label)}} [1]
  • 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 label= parameter (parameter number 4) is left blank.
