Template:Compare pages/sandbox
 | __EXPECTUNUSEDTEMPLATE__This is the template sandbox page for Template:Compare pages (diff). See also the companion subpage for test cases. |
Similar to the {{Diff}} template, 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. The major difference is that {{Diff}} is intended to show two versions of the same page, and this one creates a link to Special:ComparePages to show one version of two different pages.
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:
https://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
{{Compare pages|page or oldid for page 1|page or oldid for page 2}}
- page – The title of the page.
- oldid – The revision ID onto which the diff is generated.
All parameters are required. Omitting parameters will return an error.
Examples
| Code | Output |
|---|---|
{{Compare pages|Foo|Bar}}
|

This is the form that would be used most often. |
{{Compare pages|Foo|Bar|Difference between pages}}
|
Difference between pages |
{{Compare pages|Foo}}
|
Two pages are needed to compare. |
{{Compare pages||Bar}}
|
Two pages are needed to compare. |
