View source for Help:Magic Words

{{Help contents back}}
----
This is an organized index of Magic words used in MediaWiki.  

A "'''[[Magic (programming)|magic]] word'''" is a symbol which is recognized by the MediaWiki software and which when seen in the non-commented text of the page, triggers the software to do something other than display that symbol, or transclude a page with that name, but instead to use the symbol directly.   A magic word can be:
*an upper case word, preceded and followed by two underscores, e.g. '''<nowiki>__NOTOC__</nowiki>''' 
*an XML object, coded similar to HTML, preceded by "<" (and for the end tag "/") and followed by ">", as in '''&lt;nowiki>'''...'''&lt;/nowiki>'''
*a [[help:parser function|parser function]]: similar to a template, a word preceded by the symbols "'''<nowiki>{{</nowiki>'''" and followed by "'''<nowiki>}}</nowiki>'''", and optionally parameter definitions between pipe characters, except that the part before the first pipe (or without pipes, the text between the braces) contains a colon ("''':'''"), e.g. <nowiki>{{</nowiki>'''ns:'''3}} and {{'''#ifexpr:'''<nowiki>{{{1}}}>3|large|small}}</nowiki>
*a [[help:variable|variable]]: similar to a template without parameters, a word preceded by the symbols "'''<nowiki>{{</nowiki>'''" and followed by "'''<nowiki>}}</nowiki>'''", except the word used is in all upper case, e.g. '''<nowiki>{{CURRENTDAY}}</nowiki>'''  
*a template modifier
*an image modifier

If a page in the template namespace has the same name as a magic word, the magic word will be invoked instead.  If you discover you absolutely have to define a template with the same name as a magic word, prefix the name of the template with "'''msg:'''" or the name of the template namespace ("'''Template:'''").  See below for further details if you need this feature.

Tags which are used on this page such as "'''[MW1.5+]'''" indicate the version that first supported the magic word. "XYZ" indicates user input, which is used in the example.

==Magic words between double underscores==

! Word 
! Explanation
|-
| <nowiki>__NOEDITSECTION__</nowiki>
| Hides the edit links beside headings.
|-
| <nowiki>__NEWSECTIONLINK__</nowiki>
| '''[MW1.7+]''' Gives a "+"-link next to the edit-tab to make a new section on a non-talk page.
|-
| <nowiki>__NOCONTENTCONVERT__</nowiki><br /><nowiki>__NOCC__</nowiki>
| Don't perform the content language conversion  (character and phase) in article display; for example, Chinese zh with zh_cn, zh_tw, zh_sg, zh_hk.
|-
| <nowiki>__NOGALLERY__</nowiki>
| '''[MW1.7+]''' This magic word allows images in category pages to be displayed as inline links instead of gallery.
|-
| <nowiki>__NOTITLECONVERT__</nowiki><br /><nowiki>__NOTC__</nowiki>
| Like <nowiki>__NOCC__</nowiki> but affecting article title only.
|-
| <nowiki>__END__</nowiki>
| Allows for trailing whitespace to be included in the page save (does not seem to work anymore).
|-
| <nowiki>__START__</nowiki>
| This magic word has no effect but an ID in <tt>MagicWord.php</tt> (<code>MAG_START</code>).
|}<br clear="left" />

==XML-style tags==
'''nowiki''': &lt;nowiki>'''...'''&lt;/nowiki>, disables expansion/interpretation of templates, link syntax, formatting syntax, etc.: <nowiki>&lt;nowiki>'''[[{{tc}}]]'''&lt;/nowiki></nowiki> gives <nowiki>'''[[{{tc}}]]'''</nowiki> 
'''pre''': &lt;pre>'''...'''&lt;/pre>, ditto, also for multiple lines; it is rendered with a new paragraph at the start and end: a&lt;pre><nowiki>'''[[{{tc}}]]'''</nowiki>&lt;/pre>b gives a<pre>'''[[{{tc}}]]'''</pre>b
'''math''': &lt;math>'''...'''&lt;/math>, e.g. <nowiki><math>\sqrt{a^2+b^2}</math></nowiki> gives <math>\sqrt{a^2+b^2}</math>; see [[Help:Displaying a formula]]
<br>
'''hiero''': &lt;hiero>'''...'''&lt;/hiero>, e.g. <nowiki><hiero>A1</hiero></nowiki> gives: <hiero>A1</hiero>

== Variables ==
:''For details see [[Help:Variable]]''

===Time=== 
The time in [[:en:UTC|UTC]].  Note that if the page was displayed by the same user and has not changed (has not been edited) since the last time it was displayed, it is possible that the page may be cached (by the user's browser) and the displayed time or date may not change.  Also, if a heavily used page, rather than freshly rendered by the software each time it is generated, is instead being retrieved from a caching system (such as the main page on Wikipedia) the date or time may not change from the last time the page was originally retrieved by the caching hardware or software.

It does not seem possible to use padleft and padright for padding with characters with a multi-character code, such as <code>&amp;nbsp;</code>, which would be useful with padleft for [[Help:Sorting|sorting tables]] with Javascript.

Padding "0" does not work, it returns the same. This seems to be a bug.<ref>Function pad in includes/CoreParserFunctions.php puts, oddly, the $string itself as a condition for the padding. To be reported as bug.</ref>

== Template modifiers ==
{| class="wikitable" border="2" cellpadding="4" cellspacing="0" 
! Usage 
! Explanation
|-
| <nowiki>{{:xyz}}</nowiki>
| A bare colon is not a template modifier, it's the prefix for the main namespace. Test e.g. article {&#123;:UTC&#125;} vs. template {&#123;UTC&#125;}.<br>Using this syntax you include the text of the main namespace article xyz in another article.
|-
| <nowiki>{{int:xyz}}</nowiki>
| Shorthand for <nowiki>{{MediaWiki:xyz}}</nowiki>, rendered as {{int:xyz}} if [[MediaWiki:xyz]] doesn't exist. See also [[Help:System message]].
|-
| <nowiki>{{msg:xyz}}</nowiki>
| Even if there is a magic word named "xyz", use template:xyz unless the template doesn't exist (equivalent to <nowiki>{{template:xyz}}</nowiki>). Normally, magic words have priority when there is a conflict.
|-
| <nowiki>{{msgnw:xyz}}</nowiki>
| The unevaluated wikitext is rendered. See [[Help:Template#msgnw|msgnw]].
|-
| <nowiki>{{raw:xyz}}</nowiki>
| '''[MW1.6+]''' Equivalent to <code><nowiki>{{msg:xyz}}</nowiki></code> above<ref>[http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=12925 Wikimedia SVN revision 12925]</ref>.
|-
| <nowiki>{{subst:xyz}}</nowiki>
| In the wikitext, the tag is substituted by the ''content'' (single-level evaluation only), see [[Help:Substitution]].
|}{{-}}

== Image modifiers ==
:''For details see [[w:en:Wikipedia:Extended image syntax]].''
These are [[Help:Image page|image]] modifiers used in <code><nowiki>[[Image:title.ext|modifier|...|modifier]]</nowiki></code> links. Some are mutually exclusive, and then the last specified wins.

=== Size ===
The last unrecognized modifier is used as '''caption''' for ''framed'' images or together with ''thumbnail''s. It's also used as description <tt>alt=</tt>''text''.
{| class="wikitable" border="2" cellpadding="4" cellspacing="0" 
! Word 
! Usage 
! Explanation
|-
| framed<br />frame<br />enframed
| <nowiki>[[Image:Mediawiki.png|framed]]</nowiki>
| Places an image in a ''frame'' with a description. Uses original size and stubbornly ignores width parameter if given.<br>In general, far better to use thumb, as is only suitable for small images.
|-
| border
| <nowiki>[[Image:Mediawiki.png|border]]</nowiki>
| Shows a 1px border around the image.
|-
| thumbnail<br />thumb
| <nowiki>[[Image:Mediawiki.png|thumbnail]]</nowiki>
| Modifies image size, sets it to dependant on user's favourite thumbnail size in their preferences, or on the given width parameter (see below).
|-
| thumb=''xyz''
| <nowiki>[[Image:Mediawiki.png|thumb=Wiki.png]]</nowiki>
| Manualthumb: instead of displaying an automatically-sized thumbnail for <var>Mediawiki.png</var>, display the image <var>Wiki.png</var>.
|-valign="top"
| ''width'' px<br>100x200px
| <nowiki>[[Image:Mediawiki.png|40px]]</nowiki><br><nowiki>[[Image:Mediawiki.png|100x200px]]</nowiki>
| Scales image to given ''width''&#160; in pixels<br>Scales image to no more than 100 pixels wide and no more than 200 high, but image scaled to retain it's true aspect ratio within the boundary specified.
|}{{-}}

=== Position ===
:''For details see [[Help:Images_and_other_uploaded_files]]''
The positions are mutually exclusive; the last specified wins. [[:Template:-]] can stop floating. For inline images only modifier ''px'' (see above) is supported.

! Word 
! Usage 
! Explanation
|-
| right
| <nowiki>[[Image:Mediawiki.png|right]]</nowiki>
| Modifies position, floats the image to the right.
|-
| <nowiki>left</nowiki>
| <nowiki>[[Image:Mediawiki.png|left]]</nowiki>
| Modifies position, floats the image to the left.
|-
| <nowiki>none</nowiki>
| <nowiki>[[Image:Mediawiki.png|none]]</nowiki>
| Explicitly states that the image should not float.
|-

| ''count'' '''1''' yields ''form1'' (singular), [[w:Plural|plural]] transformations are used for languages like [[:ru:|Russian]] [http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3/languages/classes/LanguageRu.php] based on "count mod 10".
|}{{-}}

"Grammar" and "Plural" are language-dependent functions, defined in [http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3/languages/classes/LanguageCs.php], [http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3/languages/classes/LanguageRu.php], etc. (note that in PHP, the modulo operator is the percent sign).

"Grammar" can either be applied to predefined words only, or to arbitrary words, depending on whether the definition is just a 2D array, or involves string manipulations. See also [[:cs:Šablona:Wikivar/GRAMMAR]].

"Plural" is a site-language-dependent switch function, controlled by function convertPlural in Language.php (which distinguishes between 1 and "not 1"), for some languages overridden in Languagexx.php, e.g. for French (which distinguishes between <=1 and >1) and Russian (oddly, first option is 1, 21, 31,.., 91, 101, 121, .., second is 2, 3, 4, 22, 23, 24, 31, 32, 33, 41,.., 94, 102, 103, 104,.., 122, 123,.., and else the third).

As opposed to [[ParserFunctions]], "plural" accepts points and commas in numbers and interprets them in a site-language-specific way (depending on $separatorTransformTable in Messagesxx.php); on this site:
*<nowiki>{{plural:1.000|a|b|c}}</nowiki> gives {{plural:1.000|a|b|c}}
*<nowiki>{{plural:1,000|a|b|c}}</nowiki> gives {{plural:1,000|a|b|c}}

(on e.g. the German and the Dutch sites reversed w.r.t. the result on English sites).
