Extension:Cite

The Cite extension allows a user to create references as footnotes on a page. It adds two parser hooks to MediaWiki,  and  ; these operate together to add citations to pages.

Usage
The basic concept of the &lt;ref> tag is that it inserts the text enclosed by the ref tags as a footnote in a designated section, which you indicate with the placeholder tag &lt;references />. This format cannot be used interchangeably with the older format — you must pick one or the other.

Additional placeholder tags &lt;references /> can be inserted in the text, and all &lt;ref> tags up to that point will be inserted there.

If you forget to include &lt;references /> in the article, the footnotes will not disappear, but the references will be displayed at the end of the page.

This page itself uses footnotes, such as the one at the end of this sentence. If you [ view the source] of this page by clicking "Edit this page", you can see a working example of footnotes.

{| class="wikitable" ! width="50%" | Wikitext ! Rendering

The Sun is pretty big. The Moon, however, is not so big.

Notes

This is an example of multiple references to the same footnote.

Such references are particularly useful when citing sources, if different statements come from the same source. Any reused tag should not contain extra content, that will spawn an error. Only use empty tags in this role.

A concise way to make multiple references is to use empty ref tags, which have a slash at the end. Although this may reduce redundant work, please be aware that if a future editor removes the first reference, this will result in the loss of all references using the empty ref tags.

Notes

This is an example of merging multiple texts into the same footnote.

References  tag inserts the text of all the citations which have defined in   tags up to that point in the page. For example, based on the citations above, there should be reference for the note group.

{| class="wikitable" ! width="50%" | Wikitext ! Result
 * , which incorporates . It provides an optional parameter to display the reference list in multiple columns. For instance, the English, Hindi and Interlingua Wikipedias use the css selector   to make the reference text smaller than normal text.

If a page includes more than one  list, each list includes the   tags defined after the previous references list. If these references lists are produced by templates, each one lists the ref tags defined before the first references list, and there is an error message saying that there is a ref tag but not a references list.

Grouped references
This may be disabled by  if desired.

The following example generates separate reference lists for citations and miscellaneous footnotes:

{| class="wikitable" ! width="50%" | Wikitext ! Result
 * According to scientists, the Sun is pretty big In fact, it is very big
 * According to scientists, the Sun is pretty big In fact, it is very big
 * According to scientists, the Sun is pretty big In fact, it is very big

Notes  element.

Separating references from text
In-text references make it easy to copy the text to another page; on the other hand, they make it hard to read. References containing a lot of data, quotes or elaborate citation templates can make up a significantly larger fraction of the source than the text that will actually be visible. To avoid this, recent versions of the extension allow moving some or all of the references into the  section, to the place where they will actually appear to the reader.

Thus, the code above will have the same output as the first example above, although the numbering and order of the references will not in general be the same.

Substitution and embedded parser functions
Since Cite's  tag is parsed before MediaWiki's parser functions (e.g.  ) or variables (e.g.  ) or before  , these will not work inside of citation references.

Instead, you have to use the help>Special:MyLanguage/Help:Magic words#Miscellaneous|magic word  .


 * MediaWiki:Cite references link many


 * MediaWiki:Cite references link many format

Putting $3 between the undefined tags changes the links from 1.0, 1.1, 1.2 to a, b, c etc…

Searching for these 3 pages for the first time will result in no matches. Simply click "Create this page" to edit the code. The changes will not show up until a page with references is rebuilt.

Set reference and reference number highlighting
Add the following code to the MediaWiki:Common.css page.
