Wikipedia:Complete diff and link guide

From Wikipedia, the free encyclopedia
This is an old revision of this page, as edited by 118.209.244.174 (talk) at 10:58, 28 January 2019. The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

Timestamp limits

More complicated linking can be achieved using timestamps in the linking URLs. These take the form YYYYMMDDhhmmss, where YYYY is the year, MM is the month, DD is the day, hh is the hour, mm is the minutes and ss is the seconds. For example, 20070814233520 is 23:35:20 on 14th August 2007. This allows specific linking to parts of a contributions list or a page or user log, as shown above. One use of these timestamps is to link to a specific range of edits by a user.

To link to a range of sequential edits by a user, find the date and time of the last edit and generate a timestamp as above. Then set the limit to the number of edits required. The results will change if any of the edits are deleted (e.g. if one of the articles that was edited gets deleted). An example of this is:

Similarly, a permanent diff to a specific revision history of a user page may be generated:

This would give the last 25 items in the revision history of User talk:Bishonen before 2009-04-17, 22:33:00 UTC (22:33 UTC on 17 April 2009).

  1. The best way is using {{Diff2}}. For instance, {{Diff2|512088043|example edit}} gives example edit.
  2. Diffs and links will work if they're simply pasted into your text like this: http://en.wikipedia.org/w/index.php?title=Deep_End_Live!&diff=prev&oldid=512088043.
    Or you can make them neater by putting single (not double) square brackets round them. Typing this: [http://en.wikipedia.org/w/index.php?title=Deep_End_Live!&diff=prev&oldid=512088043] will give a note like this:[1].
    Or you can make them elegant by wrapping them into a word in your text. Typing this: [http://en.wikipedia.org/w/index.php?title=Deep_End_Live!&diff=prev&oldid=512088043 example edit] will give example edit link. Notice the space between the link and the wrapper word.
  3. Or you can use {{Diff}}: {{Diff|Deep End Live!|prev|512088043|example edit}}, which gives example edit. The template's documentation gives examples of the various formats available.

When using URLs (and not the two templates) the http:// must be used. However, the page name after the "title=" part only serves to make the URL more readable - it can be left out (http://en.wikipedia.org/w/index.php?oldid=191637801), or even manipulated without affecting the target of the link. (For example, http://en.wikipedia.org/w/index.php?title=Good&oldid=191637801 actually points to a version of the article Evil.) This is the reason why {{Diff2}} works, and has occasionally been abused to deceive casual readers.

The {{fullurl:PAGE_TITLE|other=URL parts&go=here}} syntax expands to a http:// link and can be used in almost all cases that a http:// link can be used, but is shorter and will not inadvertently bounce users between the two servers.

Also, be aware that diff links can also be created between non-consecutive versions (see Help:Page history). Thus, a diff link might show the changes from several users at once, but only one of them will displayed on the right hand side. It is even possible to create diff links which compare versions of different pages. Example: //en.wikipedia.org/w/index.php?title=Phillips,_Nebraska&diff=179085783&oldid=179088483 compares a version of Phillips, Nebraska with a version of Hordville, Nebraska. This can be used to highlight copy and paste actions. Another possible use is to create a "diff" for a page creation by comparing to a blank version of another page. Example: The creation //en.wikipedia.org/w/index.php?title=Barack_Obama&oldid=2814496 can be compared to the blank //en.wikipedia.org/w/index.php?title=Wikipedia_talk:How_to_edit_a_page&oldid=44 by inserting =44&diff after oldid in the creation url: //en.wikipedia.org/w/index.php?title=Barack_Obama&oldid=44&diff=2814496.

How to display only the diff

To the URL of the diff, append &diffonly=1

  • a regular diff, showing the change and the resulting version of the page
