Template:Compare pages
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
