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 timestamp link for the edit. The timestamp link is in this form:
http[s]://test.justapedia.org/w/index.php?title=SomePageName&oldid=442212827
The number after oldid=
is the revision ID.
Given one or two revision IDs, you can construct links to several types of diffs.
Usage
{{Diff|title|diff|oldid|label|diffonly=yes}}
title
– The title of the page (optional in most cases)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 (optional)—no label will generate a numbered link as the label.|diffonly=yes
– Displays the page comparisons only (optional)—parameter name required if used.
Only the diff parameter is required; all other parameters are optional. Omitted parameters must be empty (by using a double pipe). You can also use the named parameters title
, 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): ||
.
