Extension:Cite/fr

''This page is about the extension. See also Help:Footnotes, and Wikipedia:Footnotes for the use in the English Wikipedia.''

Cite is an extension which 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.

Utilisation
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.

If you forget to include &lt;references /> in the article, the footnotes will not appear, but a red error message 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.

Exemple
 According to scientists, the Sun is pretty big. &lt;ref>E. Miller, The Sun, (New York: Academic Press, 2005), 23-5.&lt;/ref> The Moon, however, is not so big. &lt;ref>R. Smith, "Size of the Moon", Scientific American, 46 (April 1978): 44-6.&lt;/ref>

'''&lt;references /> 

Multiple uses of the same footnote
To give a footnote a unique identifier, use &lt;ref name="name">. You can then refer to the same footnote again by using a ref tag with the same name. The text inside the second tag doesn't matter, because the text already exists in the first reference. You can either copy the whole footnote, or you can use a terminated empty ref tag that looks like this: &lt;ref name="name" />. The quotes are not required (but still correct) if the name contains no embedded spaces. The space before the closing "/" may be omitted.

In the following example, the same source is cited three times.

 This is an example of multiple references to the same footnote. &lt;ref name&#61;"multiple">Remember that when you refer to the same footnote multiple times, the text from the first reference is used.&lt;/ref>

Such references are particularly useful when citing sources, if different statements come from the same source. &lt;ref name&#61;"multiple">This text is superfluous, and won't show up anywhere. We may as well just use an empty tag.&lt;/ref>

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. &lt;ref name&#61;"multiple" />

&#61;=Notes==

&lt;references /> 

The text above gives the following result in the article (see also section below):

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

Such references are particularly useful when citing sources, when different statements come from the same source.

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.

identifiers require alphabetic characters; solely relying on numerals will generate an error message.

Merging two texts into a single reference (wikisource issue)
A typical wikisource issue is, how to merge into one reference texts split into different pages. This can be done using a &lt;ref name="name"> tag for the first part of the reference, and tagging the following parts into different pages with a tag &lt;ref follow="name">.

Here an example, deriving the text used into previous section:

Result:

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

When using this syntax into Page: namespace, take care that the ref follow part of the footnote is transcluded too into the same ns0 page, where the first part of footnote is transcluded. Use appropriately section tags to get this result. To also remind users that reference names should not solely be numbers, eg. and.

&lt;references /&gt;
Placing  inserts the full text of all pending inline citations defined by , anywhere on the page. For example, based on the citations above, the code:



… will yield:

, 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.

In the case of multiple references-tags on a page, each gives the references defined in the ref-tags from the previous references-tag. In the case that these references-tags are produced by templates, each gives the references defined in the ref-tags before the first references-tag, and there is an error message that there is a ref-tag but not a references-tag.

List-defined references
Instead of using a self-closing  (void element) to display pending inline citations, one can use paired tags –   – containing named references, as in: These can then be referenced via  tags, and allow one to define references at the end, instead of inline. Pending inline references will also be displayed. See Help:List-defined references for an example of this use.

Grouped references
This may be disabled by  if desired. However, it is enabled on the Foundation wikis.

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

 According to scientists, the Sun is pretty big &lt;ref>E. Miller, The Sun, (New York: Academic Press, 2005), 23-5.&lt;/ref>.

In fact, it is very big &lt;ref group="footnotes">Take their word for it. Don't look directly at the sun!&lt;/ref>.

&#61;=Notes==

'''&lt;references group="footnotes" />

&#61;=References==

'''&lt;references />  The anonymous group works as before, while the named group reference will show up as, and the references will look like this: section, to the place where they will actually appear to the reader. Thus,

 According to scientists, the Sun is pretty big. &lt;ref name="miller" />

The Moon, however, is not so big. &lt;ref name="smith" />

&#61;=Notes==

&lt;references>

&lt;ref name="miller">E. Miller, The Sun, (New York: Academic Press, 2005), 23-5.&lt;/ref> &lt;ref name="smith">R. Smith, "Size of the Moon", Scientific American, 46 (April 1978): 44-6.&lt;/ref>

&lt;/references> 

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  is parsed before substitution (i.e.,  ) or parser functions (i.e., ), those will not work inside of citation references. Instead, you have to use the  magic word.
 * This non-working example:


 * could be made to work using:

At this time, there is no way to create an "empty" tag (i.e., ) without triggering Cite's complaint about empty content. The workaround is to simply redefine the full tag each time you use this feature. Since such usage is likely limited to templates or other semi-automated process, this may not be too onerous.

Customization
The format of the output of  and   is almost completely customizable through MediaWiki messages, that can be modified, for example, through the MediaWiki namespace depending on the configuration of the wiki.

For a list of messages that control the output of  and   and the values, if any, that are passed to them ($1, $2, $3 ...), see the code in CVS for an up-to-date listing of their default contents.

Criticisms
The major criticism regarding Cite.php is that it renders the editing of references much more tedious. Moreover, because many casual Wikipedia users are not familar with the cryptic Wikitext tags that they find with the use of Cite.php, it is likely that the net effect of Cite.php is often to deter new users from making edits to reference sections. Although Wikipedia supposedly got its name from the Hawaiian word "wiki-wiki", meaning "quick-quick", Cite.php is arguably neither quick nor easy for the average Wikipedia user.


 * This can now be solved by separating references from the text.


 * However, at least one editor, Ta bu shi da yu, finds it useful to have the references embedded within the text when splitting articles and shifting text with footnotes around the article. With the old system, or when using Cite.php with separated references, when a paragraph with a footnote needs to be moved, multiple footnotes in the Notes section may need to be shifted. This is very difficult to do. With Cite.php and in-line references, reorganising text and splitting articles is considerably easier.

Using cite.php makes citing page numbers harder. Each reference usually cites a different page of the book/journal/article, but there is no way to indicate a different page number when using a self-closing tag. As such, all simply refer to the work as a whole, rather than to a specific page number in the work (unless the author makes each page number a seperate reference). Perhaps a future revision of cite.php could allow a page number argument to be passed to the reference like so. This would dramatically increase the reputability of the citations, because they could then be checked/verified, and the citations would be a more useful resource.


 * This can be solved by using the template on en.wikipedia to append :20 the specific :30 page number :33 to each reference. The formatting has been simulated here because the MediaWiki site does not contain the  template. If this had been an actual Wikipedia page, the full template with its many options could have been utilized.

Comparing ref/note style and Cite.php style
They are actually very similar.


 * To make a single use footnote:
 * Ref/note
 *   at the in-text place.
 *  # text of note at the proper place in the Notes list.
 * Cite.php
 *   at the in-text place.
 * (Only needed once per article)  under the Notes heading.
 * To make a multiple use footnote:
 * Ref/note
 * With strict ref/note style this was impossible, but a number of alternative forms had been created, for the details of which, see the appropriate pages.
 * Cite.php
 *   at each in-text place.
 * Alternatively    A self-closing tag on every use after name=foo has been defined.
 * (Only needed once per article)  under the Notes heading; exactly the same as to make a single-use note.

Harvard references extension
There is an Extension:HarvardReferences that can be used to support "Harvard" ("author - date") system of references, e.g.  [Smith 2010:1] . This reference system is often used in scientific literature. Both extensions are compatible. Moreover, links in "Harvard" system can be inserted into body of ref-link, and vice versa. It may be helpful to support book-style comments/subnotes with a "scientific" source references. For example:
