'''Magic words''' are strings of text that MediaWiki associates with a return value or function, such as time, site details, or page names. This page is about usage of standard magic words; for a technical reference, see {{Mediawiki|Manual:Magic words}}.
+
{{Notice|1=
 +
See '''[[mw:Help:Magic words|Help:Magic words]] on [[mw:|www.mediawiki.org]]''' for more magic words in the MediaWiki software. The page here is currently kept for things not yet merged to www.mediawiki.org and for documentation specific to the Wikimedia Foundation. If something is missing from both pages, check the [//meta.wikimedia.org/w/index.php?title=Help:Magic_words&oldid=3392669 full version of this page] and restore the lacking information.

}}
  
−
There are three general types of magic words:
+
{{H:h|editor toc}}
−
*'''[[#Behavior switches|Behavior switches]]''': these are uppercase words surrounded by double underscores, ''e.g.'' '''__FOO__'''
 
−
*'''[[#Variables|Variables]]''': these are uppercase words surrounded by double braces, ''e.g.'' '''<tt><tt><nowiki>{{FOO}}</nowiki></tt></tt>'''. As such, they look a lot like [[Help:Templates|templates]].
 
−
*'''[[#Parser functions|Parser functions]]''': these take parameters and are either of the form '''<tt><tt><nowiki>{{foo:...}}</nowiki></tt></tt>''' or '''<tt><tt><nowiki>{{#foo:...}}</nowiki></tt></tt>'''. See also {{mediawiki|Help:Extension:ParserFunctions}}.
 
  
−
Page-dependent magic words will affect or return data about the ''current'' page (by default), even if the word is added through a transcluded template or included system message.
+
This is an organized index of magic words used in MediaWiki.
  
−
==Behavior switches==
+
A "'''[[w:Magic (programming)|magic]] word'''" is a symbol 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 behavior switch controls the layout or behaviour of the page and can often be used to specify desired omissions and inclusions in the content.
 
  
−

A magic word can be:
−
|-
+
* a behavior switch, called using an upper case word, preceded and followed by pairs of underscores, e.g. '''<nowiki>__NOTOC__</nowiki>'''
−
!{{Hl2}}| Word
+
* [[Help:XML-style tags|XML-style tags]], preceded by "<" (and for the end tag "/") and followed by ">", as in '''&lt;nowiki>'''...'''&lt;/nowiki>'''
−
!{{Hl2}}| Description
+
* 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>
−
!{{Hl2}}| Versions
+
* 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>'''

==Variables==
+
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.
−
Variables return information about the current page, wiki, or date. Their syntax is similar to [[Help:Templates|templates]]. Variables marked as "<span style="background:#FED;">'''[expensive]'''</span>" are tracked by the software, and the number that can be included on a page is limited.
 
  
−
If a template name conflicts with a variable, the variable will be used (so to transclude the template [[{{ns:10}}:PAGENAME]] you would need to write <code><tt><nowiki>{{</nowiki>{{ns:10}}:PAGENAME<nowiki>}}</nowiki></tt></code>). In some cases, adding parameters will force the parser to treat a variable as a template; for example, <code><tt><nowiki>{{CURRENTDAYNAME|x}}</nowiki></tt></code> transcludes [[{{ns:10}}:CURRENTDAYNAME]].
+
== Variables ==
  
−
===Date & time===
+
:''For details see [[Help:Variable]]''
−
The following variables return the current date and time in UTC.
 
  
−
Due to MediaWiki and browser caching, these variables frequently show when the page was ''cached'' rather than the current time.

These are [[Help:Image page|image]] modifiers used in <code><nowiki>[[File:title.ext|modifier|...|modifier]]</nowiki></code> links. Some are mutually exclusive, and then the last specified wins. The last unrecognized modifier is used as '''caption''' for [[w:framed image|''framed'' images]] or together with ''[[w:thumbnail|thumbnail]]s''. It's also used as description <tt>alt=</tt>''text''.
−
Revision variables return data about the '''latest edit to the current page''', even if viewing an older version of the page.

Numbers returned by these variables normally contain separators (commas or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example, <code><tt><nowiki>{{NUMBEROFPAGES}}</nowiki></tt></code> &rarr; {{NUMBEROFPAGES}} and <code><tt><nowiki>{{NUMBEROFPAGES:R}}</nowiki></tt></code> &rarr; {{NUMBEROFPAGES:R}}). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example <code><tt><nowiki>{{PAGESINCATEGORY:Help}}</nowiki></tt></code> and <code><tt><nowiki>{{PAGESINCATEGORY:Help|R}}</nowiki></tt></code>).

==Parser functions==
 
−
 
 
−
Parser functions are very similar to variables, but take one or more parameters (technically, any magic word that takes a parameter is a parser function), and the name is sometimes prefixed with a hash to distinguish them from templates.
 
−
 
 
−
This page only describes parser functions that are integral to the MediaWiki software. Other parser functions may be added by MediaWiki extensions such as the {{mediawiki|Extension:ParserFunctions|ParserFunctions extension}}. For those see [[Help:Extension:ParserFunctions]].

"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, which uses a grammar case for amounts ending in 1 (1, 21, 31,...), another case for amounts ending in 2 to 4 (2, 3, 4, 22, 23, 24, ...) and still another case for the remaining quantities.
  
−
Note: In the example above, "your pref" refers to your date preference on the current MediaWiki wiki only.

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:
−
| Formats an unlinked date based on user "Date format" preference, and adds metadata tagging it as a formatted date. For logged-out users and those who have not set a date format in their preferences, dates can be given a default: <tt>mdy</tt>, <tt>dmy</tt>, <tt>ymd</tt>, <tt>ISO&nbsp;8601</tt> (all case sensitive). If only the month and day are given, only <tt>mdy</tt> and <tt>dmy</tt> are valid. If a format is not specified or is invalid, the input format is used as a default. If the supplied date is not recognized as a valid date (specifically, if it contains any metadata such as from a nested use of these or a similar template), it is rendered unchanged, and no (additional) metadata is generated.<br/><small>{{warning}}Although the ISO 8601 standard requires that dates be in the Gregorian calendar, the ISO parameter in this function will still format dates that fall outside the usual Gregorian range (e.g. dates prior to 1583). Also, the magic word cannot properly convert between negative years (used with ISO 8601) and years BC or years BCE (used in general writing).</small>

The final digits or characters in the base replace the final characters in the padding; i.e. <nowiki>{{padleft:44|3|0}}</nowiki> produces {{padleft:44|3}}.

Comment See Help:Magic words on www.mediawiki.org for more magic words in the MediaWiki software. The page here is currently kept for things not yet merged to www.mediawiki.org and for documentation specific to the Wikimedia Foundation. If something is missing from both pages, check the full version of this page and restore the lacking information.


MediaWiki Handbook: Contents, Readers, Editors, Moderators, System admins +/-

This is an organized index of magic words used in MediaWiki.

A "magic word" is a symbol 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:

  • a behavior switch, called using an upper case word, preceded and followed by pairs of underscores, e.g. __NOTOC__
  • XML-style tags, preceded by "<" (and for the end tag "/") and followed by ">", as in <nowiki>...</nowiki>
  • a parser function: similar to a template, a word preceded by the symbols "{{" and followed by "}}", 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. {{ns:3}} and {{#ifexpr:{{{1}}}>3|large|small}}
  • a variable: similar to a template without parameters, a word preceded by the symbols "{{" and followed by "}}", except the word used is in all upper case, e.g. {{CURRENTDAY}}
  • 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.

Template modifiers

Usage Explanation
{{:xyz}} A bare colon is not a template modifier, it's the prefix for the main namespace. Test e.g. article {{:UTC}} vs. template {{UTC}}.
Using this syntax you include the text of the main namespace article xyz in another article.
{{int:xyz}} Same as {{MediaWiki:xyz}}, except standard message translation is applied depending on subpages and content/user/uselang language. Another difference is: this doesn't appear under "Templates used on this page:". Rendered as ⧼xyz⧽ if MediaWiki:xyz doesn't exist. See also Help:System message.
{{msg:xyz}} Even if there is a magic word named "xyz", use template:xyz unless the template doesn't exist (equivalent to {{template:xyz}}). Normally, magic words have priority when there is a conflict.
{{msgnw:xyz}} The unexpanded wikitext is rendered (more or less, for details see msgnw).
{{raw:xyz}} [MW1.6+] Equivalent to {{msg:xyz}} above<ref>Wikimedia SVN revision 12925</ref>.
{{subst:xyz}} 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 image modifiers used in [[File:title.ext|modifier|...|modifier]] links. Some are mutually exclusive, and then the last specified wins. The last unrecognized modifier is used as caption for framed images or together with thumbnails. It's also used as description alt=text.

Size

Word Usage Explanation
framed
frame
enframed 		[[File:Mediawiki.png|framed]] Places an image in a frame with a description. Uses original size and stubbornly ignores width parameter if given.
In general, far better to use thumb, as is only suitable for small images.
border [[File:Mediawiki.png|border]] Shows a 1 pixel border around the image.
thumbnail
thumb 		[[File:Mediawiki.png|thumbnail]] Modifies image size, sets it dependent on user's favorite thumbnail size in one's preferences, or on the given width parameter (see hereafter).
thumb=xyz [[File:Mediawiki.png|thumb=Wiki.png]] Manual thumbnail: instead of displaying an automatically-sized thumbnail for Mediawiki.png, display the image Wiki.png.
width px
100x200px 		[[File:Mediawiki.png|40px]]
[[File:Mediawiki.png|100x200px]] 		Scales image to given width  in pixels.
Scales image to no more than 100 pixels wide and no more than 200 high, but image scaled to retain its 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:Clear can stop floating. For inline images only modifier px (see hereinbefore) is supported.

Word Usage Explanation
right [[File:Mediawiki.png|right]] Sets top of image to the right margin, text will flow from the left.
left [[File:Mediawiki.png|left]] Sets top of image to the left margin, content text will flow from the right.
none [[File:Mediawiki.png|none]] Image will be alone at left, content text will not appear with image.
center
centre 		[[File:Mediawiki.png|center]] Like none with image centered.


Miscellany

Word Example Explanation
{{DISPLAYTITLE:xyz}} no inline output [MW 1.7+] Modify the page's title [1], enabled in Wikimedia projects since June 2007 ([2]). Also see $wgAllowDisplayTitle.
{{DIRMARK}}
{{DIRECTIONMARK}} 		‎
‎ 		[MW 1.7+] U+200E left-to-right or U+200D right-to-left mark.
{{CONTENTLANGUAGE}} en [MW 1.7+] Code of the site's default interface language ($wgLanguageCode).
{{DEFAULTSORT:xyz}} no inline output [MW 1.10+] Sets a default category sort key for the whole current page (also applying for category tags before this tag)<ref>"Technology report", English Wikipedia Signpost, January 2007</ref>.
#REDIRECT #REDIRECT [[target]]
at top of source page 		Creates a redirect to another page (to the target page).


Despite its name MAGICNUMBER is no magic word, the ISBN magic works only on the MediaWiki:Booksources page used by Special:Booksources, but talking about [[{{ns:4}}:{{int:Booksources}}|{{ns:8}}:Booksources]] in a way working on any MediaWiki installation is esoteric enough to be noted here.

Language-dependent word conversions

Word Example Explanation
{{CURRENTMONTHNAMEGEN}} April Genitive form of month name used for Czech, Polish, Ukrainian[3]
{{LOCALMONTHNAMEGEN}} April Genitive form of month name used for Czech, Polish, Ukrainian (local time)
{{grammar:case | word }} {{grammar:7sg|Wikipedie}}
on cs: is Wikipedií. 		Derived word forms in inflected languages like Czech [4]
{{plural:count |form1 |form2 }}
{{plural:count |1st | 2nd | 3rd }} 		{{plural: 2 | is | are }}
outputs are
{{plural: 1 | this | these }}
outputs this
{{plural: 0 | his | their }}
outputs their 		count 1 yields form1 (singular), plural transformations are used for languages like Russian [5] based on "count mod 10".


"Grammar" and "Plural" are language-dependent functions, defined in [6], [7], 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, which uses a grammar case for amounts ending in 1 (1, 21, 31,...), another case for amounts ending in 2 to 4 (2, 3, 4, 22, 23, 24, ...) and still another case for the remaining quantities.

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:

  • {{plural:1.000|a|b|c}} gives a
  • {{plural:1,000|a|b|c}} gives b

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

"Plural" is used in various system messages, e.g. message with id 'nmembers' (talk), where it uses interface language instead of site language.
