View source for Help:Magic words

{{TOCRight}}

'''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 explains only the standard magic words; for a technical reference, see {{ll|Manual:Magic words}}.

There are three general types of magic words:

* '''[[#Behavior switches|Behavior switches]]''': these are usually written as uppercase words surrounded by double underscores, ''e.g.'' '''<code>__FOO__</code>'''.
* '''[[#Variables|Variables]]''': these are uppercase words surrounded by double braces, ''e.g.'' '''<code><nowiki>{{FOO}}</nowiki></code>'''. As such, they look a lot like [[Special:MyLanguage/Help:Templates|templates]].
* '''[[#Parser functions|Parser functions]]''': these take parameters and are either of the form'''<code><nowiki>{{foo:...}}</nowiki></code>''' '''<code><nowiki>{{#foo:...}}</nowiki></code>''', e.g. <code><nowiki>{{#invoke:}}</nowiki></code>. See also {{ll|Help:Extension:ParserFunctions}} and {{ll|Extension:Scribunto}}.

Variables and parser functions can use [[Special:MyLanguage/Manual:subst|subst:]], just like templates. 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.
{{anchor|Behavior switches}}
== Behavior switches == 
A behavior switch controls the layout or behavior of the page (if supported by the skin) and can often be used to specify desired omissions and inclusions in the content. Notably some of these are not supported by the [[Skin:MinervaNeue|Minerva skin]].

|  Hides the section edit links beside headings. This is especially useful where a heading is created from within a template: the normal wiki section-edit would in this case edit the template code, which is usually not what the user intends.  Use of this in a template will extend the effect to that template, the pages it's included on, ''and'' any other templates included on the same page.  For a workaround, see [[m:Special:MyLanguage/Help:Editing sections of included templates|here]].

{{anchor|Variables}}

== Variables == 
Variables return information about the current page, wiki, or date. Their syntax is similar to [[<tvar|help-templates>Special:MyLanguage/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 <tvar|code><code><nowiki>{{</nowiki>{{ns:10}}:PAGENAME<tvar|code-end><nowiki>}}</nowiki></code>). In some cases, adding parameters will force the parser to invoke a template; for example, <tvar|tpl-currentdayname-code><code><nowiki>{{CURRENTDAYNAME|x}}</nowiki></code> transcludes <tvar|tpl-currentdayname-result>[[{{ns:10}}:CURRENTDAYNAME]], ''not'' the variable.
{{anchor|Date and time}}
=== Date and time === 

The following variables return the current date and time in [[w:UTC|UTC]].

Due to MediaWiki and browser caching, these variables frequently show when the page was ''cached'' rather than the current time.

The use of those variables cause pages to be cached for a more limited number of seconds. This is configured in <tvar|MagicWordFactory>[https://github.com/wikimedia/mediawiki/blob/master/includes/MagicWordFactory.php#L122 MagicWordFactory].

The date and time magic words are formatted in the wiki content language. Since {{r|94680|1.19}}, they depend on the [[<tvar|manual-pagelang>Special:MyLanguage/Manual:Language#page-content-lang|page content language]].

=== Statistics === 

Numbers returned by these variables normally contain separators (commas, dots or spaces, depending on the local language) but can return raw numbers with the ":R" flag (for example, <tvar|nop-code><code><nowiki>{{NUMBEROFPAGES}}</nowiki></code> &rarr; <tvar|nop-result>{{NUMBEROFPAGES}} and <tvar|nop-r-code><code><nowiki>{{NUMBEROFPAGES:R}}</nowiki></code> &rarr; <tvar|nop-r-result>{{NUMBEROFPAGES:R}}).

Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example <tvar|pic><code><nowiki>{{PAGESINCATEGORY:Help}}</nowiki></code> and <tvar|pic-r><code><nowiki>{{PAGESINCATEGORY:Help|R}}</nowiki></code>, or <tvar|pic-subcats><code><nowiki>{{PAGESINCATEGORY:Help|subcats}}</nowiki></code> and <tvar|pic-subcats-r><code><nowiki>{{PAGESINCATEGORY:Help|subcats|R}}</nowiki></code>). Also applicable to <tvar|pagesize><code><nowiki>{{PAGESIZE:</nowiki>''page name''<tvar|pagesize-end><nowiki>}}</nowiki></code> hereinbefore.

The number magic words are formatted in the wiki content language. Since {{r|94680|1.19}}, it depends on the [[<tvar|manual-pagelang>Special:MyLanguage/Manual:Language#page-content-lang|page content language]].

 None of these are affected by changes to the display title using <code><nowiki>{{DISPLAYTITLE:xxxx}}</nowiki></code>; the values returned are the original page title.



The <tvar|basepagename><code><nowiki>{{BASEPAGENAME}}</nowiki></code> and <tvar|subpagename><code><nowiki>{{SUBPAGENAME}}</nowiki></code> magic words only work in namespaces that have subpages enabled. See <tvar|manual-wg-ns-with-subpages>{{mediawiki|Special:MyLanguage/Manual:$wgNamespacesWithSubpages|$wgNamespacesWithSubpages}} for information on enabling subpages.


As of [[rev:46662|1.15+]], these can all take a parameter, allowing specification of the page to be operated on, instead of just the current page:

* <code><nowiki>{{PAGENAME:Template:Main Page}}</nowiki></code> &rarr; '''{{PAGENAME:Template:Main Page}}'''

{{Warning|1=
 If the page title contains any parts that are "<code>.</code>" or "<code>..</code>", the magic word fails returning nothing.
: <code><nowiki>{{PAGENAME:one/./three}}</nowiki></code> → '''{{PAGENAME:one/./three}}'''. <small> Nothing is returned.</small>
}}

{{Warning|1= Page titles containing certain characters, such as apostrophes <code>'</code> or asterisks <code>*</code>, may produce unexpected results when handled with these magic words, e.g. <tvar|pic><code><nowiki>{{PAGESINCATEGORY:{{PAGENAME}}}}</nowiki></code>.

One simple way to fix this is wrapping the pagename in <tvar|titleparts><code><nowiki>{{</nowiki>[[Special:MyLanguage/Help:Extension:ParserFunctions#.23titleparts|#titleparts:]]<nowiki>}}</nowiki></code> from the [[<tvar|help-ext-pf>Special:MyLanguage/Help:Extension:ParserFunctions|ParserFunctions extension]].

{{anchor|Parser functions}}

== 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 [[:en:Number sign|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 <tvar|ext-pf>{{ll|Extension:ParserFunctions}}. For those see <tvar|help-ext-pf>{{ll|Help:Extension:ParserFunctions}}.

=== Namespaces === 


<tvar|ns><code><nowiki>{{ns:}}</nowiki></code> returns the current localized name for the [[<tvar|help-ns>Special:MyLanguage/Help:Namespace|namespace]] with that index, canonical name, or local alias. Thus <tvar|ns6><code><nowiki>{{ns:6}}</nowiki></code>, <tvar|ns-file><code><nowiki>{{ns:File}}</nowiki></code>, and <tvar|ns-img><code><nowiki>{{ns:Image}}</nowiki></code> (an old name for the File namespace) all return "{{ns:6}}". On a wiki where the content language is French, <tvar|ns-file-de><code><nowiki>{{ns:Fichier}}</nowiki></code> is also valid, but <tvar|ns-file-incorrect><code><nowiki>{{ns:Datei}}</nowiki></code> (the localisation of "File" in German) is not.


<tvar|nse><code><nowiki>{{nse:}}</nowiki></code> is the equivalent encoded for MediaWiki URLs. It does the same, but it replaces spaces with underscores, making it usable in external links.

| {{Anchor|formatnum}}
Takes an unformatted number ([[w:Arabic numerals|Arabic]], no group separators and <code>.</code> as decimal separator) and outputs it in the localized digit script and formatted with decimal and decimal group separators, according to the wiki's default locale. <br />
The <code><nowiki>|R</nowiki></code> parameter can be used to reverse the behavior, for use in mathematical situations: it's reliable and should be used only to deformat numbers which are known to be formatted exactly as formatnum formats them with the wiki's locale.<br/>
 The <code>NOSEP</code> ("no separators") parameter means that no group / decimal separators are changed; formatnum will only transform the digits themselves in languages which don't use the [[w:en:Hindu–Arabic numeral system|Hindu–Arabic numeral system]]. <code>NOSEP</code> can also prevent non-standard digit groupings you wouldn't expect.

{{warning|1= Leading zeroes are not removed, you can use <nowiki>{{#expr:00001}}</nowiki> instead if you have <tvar|ext-pf>{{ll|Extension:ParserFunctions}} installed.}}<br />

{{warning|1= If you don't input numbers in the exact format required, don't expect any reliable output, especially on non-English wikis.}}<br />
----



If you really need to format (according the wiki's locale) a number in unknown input format, you could try and use <code>formatnum</code> two times (but not if it can have a decimal group, or its separator will be eaten or the number won't be formatted). Be aware that this is more a hack than a regular way to proceed, thus the output may be not reliable.

''Note:'' In the example hereinbefore, "your pref" refers to your date preference on the current MediaWiki wiki only.


| {{Anchor|dateformat|formatdate}} 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: <code>mdy</code>, <code>dmy</code>, <code>ymd</code>, <code>ISO&nbsp;8601</code> (all case sensitive). If only the month and day are given, only <code>mdy</code> and <code>dmy</code> 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 similar templates), it is rendered unchanged, and no (additional) metadata is generated. <br/>

{{warning|1= 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).}}

Inserts a string of padding characters (character chosen in third parameter; default "0") of a specified length (second parameter) next to a chosen base character or variable (first parameter). The final digits or characters in the base replace the final characters in the padding; i.e. <code><nowiki>{{padleft:44|3|0}}</nowiki></code> produces {{padleft:44|3}}. The padding string may be truncated if its length does not evenly divide the required number of characters.


Only the first character of the third parameter is used in versions up to 1.12, but by version 1.15, all the characters are used.


'''[[bugzilla:16852|Bug]] (fixed in [[rev:45734|r45734]]):''' multibyte characters are interpreted as two characters, which can skew width. These also cannot be used as padding characters.

=== Localization === 


Here are the magic words which are used as main localisation tools. Other magic words will often depend on the wiki's locale and configuration or on the chosen language: see in particular [[<tvar|date>#Date and time|#Date and time]], [[<tvar|formatting>#Formatting|#Formatting]], [[<tvar|misc>#Miscellaneous|#Miscellaneous]]. More magic words are added by the <tvar|ext-translate>{{ll|Extension:Translate}}.


The usage of these magic words can be very complex, and the documentation is currently incomplete; there's some more info on [[translatewiki:Special:MyLanguage/FAQ#PLURAL|PLURAL]], [[translatewiki:Special:MyLanguage/Grammar|GRAMMAR]], [[translatewiki:Special:MyLanguage/Gender|GENDER]].

{{anchor|Transclusion modifiers}}

=== Transclusion modifiers === 


<code><nowiki>{{</nowiki>''Page name''|''optional params''}}</code> usually transcludes another page, by default from the Template:namespace.


These magic words modify that behavior.

!  Description
! width="10%" |  Version
|-
| <code><nowiki>{{:xyz}}</nowiki></code>
|
|  A bare colon is not a template modifier but the prefix for the main namespace.  Since transclusion defaults to the Template namespace, you would use for example, <tvar|code1>{&#123;:UTC&#125;} (vs. <tvar|code2>{&#123;UTC&#125;}) to include the text of the main namespace article UTC rather than Template:UTC.
|
|-
| <code><nowiki>{{int:xyz}}</nowiki></code>
|
|  Same as <tvar|mw><nowiki>{{MediaWiki:xyz}}</nowiki>, except standard message translation is applied depending on subpages and content/user/uselang language.  Another difference is: this doesn't appear under "<tvar|translatesused>{{int|templatesused}}".  Rendered as <tvar|int>{{int:xyz}} if <tvar|mw>[[MediaWiki:xyz]] doesn't exist.
