'''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}}.
+
{{Shortcut|WP:MAGIC}}
  
−
There are three general types of magic words:
+
'''Magic words''' (which include '''parser functions''', '''variables''' and '''behavior switches''')  are features of [[WP:wikitext|wikitext]] that enable various instructions to be given to the [[Help:MediaWiki|MediaWiki]] software (for example, to suppress or position the table of contents), or else serve to produce variable output, as is often required in [[WP:Templates|templates]].
−
*'''[[#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.'' '''<code><nowiki>{{FOO}}</nowiki></code>'''. As such, they look a lot like [[Help:Templates|templates]].
 
−
*'''[[#Parser functions|Parser functions]]''': these take parameters and are either of the form '''<code><nowiki>{{foo:...}}</nowiki></code>''' or '''<code><nowiki>{{#foo:...}}</nowiki></code>'''. 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.
+
A quick reference for magic words can be found on this page. For more complete and updated documentation, refer to the following pages on the MediaWiki site:
 +
*'''[[mw:Help:Magic words]]''' for all standard magic words, including the "standard" parser functions
 +
*'''[[mw:Help:Extension:ParserFunctions]]''' for some additional parser functions, including conditional expressions
  
−
==Behavior switches==
+
==General information==
−
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.
+
There are three types of magic words:
 +
*'''Behavior switches:''' uppercase words surrounded by double underscores, e.g. <tt><nowiki>__NOTOC__</nowiki></tt>, or keywords using parser function syntax
 +
*'''Variables:''' uppercase words surrounded by double braces, e.g. <tt><nowiki>{{PAGENAME}}</nowiki></tt> (thus resembling [[Help:Templates|templates]])
 +
*'''Parser functions:''' keywords (some beginning #) in double braces with parameters after a colon, e.g. <tt><nowiki>{{#expr:2+2}}</nowiki></tt>
  
−
{| class="wikitable"
+
Some magic words are case-insensitive, but not all. Whitespace is stripped from the start and end of keywords and parameters, as in template syntax.

==Variables==
+
Page-dependent magic words will affect or return data about the ''current'' page, even if the word is added through a transcluded template or included system message.
−
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><nowiki>{{</nowiki>{{ns:10}}:PAGENAME<nowiki>}}</nowiki></code>). In some cases, adding parameters will force the parser to invoke a template; for example, <code><nowiki>{{CURRENTDAYNAME|x}}</nowiki></code> transcludes [[{{ns:10}}:CURRENTDAYNAME]] ''not'' the variable.
+
It is possible to [[Help:Substitution|substitute]] parser functions and variables in the same way that templates are substituted (using the <tt>subst:</tt> keyword). This causes their current value (as evaluated at the time of substitution) to be written into the wikitext.
  
−
===Date and time===
+
==Behavior switches==
−
The following variables return the current date and time in UTC.
+
''For documentation, refer to the [[mw:Help:Magic words#Behavior switches|Behavior Switches]] section of the MediaWiki page.''
 +
*<tt><nowiki>__NOTOC__</nowiki></tt> (can appear anywhere in the wikitext; suppresses the table of contents)
 +
*<tt><nowiki>__FORCETOC__</nowiki></tt> (can appear anywhere in the wikitext; makes a table of contents appear in its normal position above the first header)
 +
*<tt><nowiki>__TOC__</nowiki></tt> (places a table of contents at the word's position)
  
−
Due to MediaWiki and browser caching, these variables frequently show when the page was ''cached'' rather than the current time.
+
*<tt><nowiki>__NOEDITSECTION__</nowiki></tt> (hides the section "edit" links beside headings)
 +
*<tt><nowiki>__NEWSECTIONLINK__</nowiki></tt> (adds a "+" link for adding a new section on a non-"Talk" page)
 +
*<tt><nowiki>__NONEWSECTIONLINK__</nowiki></tt> (removes the "+" link on "Talk" pages)

===Statistics===
 
−
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><nowiki>{{NUMBEROFPAGES}}</nowiki></code> &rarr; {{NUMBEROFPAGES}} and <code><nowiki>{{NUMBEROFPAGES:R}}</nowiki></code> &rarr; {{NUMBEROFPAGES:R}}). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example <code><nowiki>{{PAGESINCATEGORY:Help}}</nowiki></code> and <code><nowiki>{{PAGESINCATEGORY:Help|R}}</nowiki></code>). Also applicable to <code><nowiki>{{PAGESIZE:</nowiki>''page name''<nowiki>}}</nowiki></code> above.

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.

Add <tt>|R</tt> to return numbers without commas.

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]].

| 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/><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>

Revision as of 07:23, 24 February 2011

Shortcut:
WP:MAGIC

Magic words (which include parser functions, variables and behavior switches) are features of wikitext that enable various instructions to be given to the MediaWiki software (for example, to suppress or position the table of contents), or else serve to produce variable output, as is often required in templates.

A quick reference for magic words can be found on this page. For more complete and updated documentation, refer to the following pages on the MediaWiki site:

General information

There are three types of magic words:

  • Behavior switches: uppercase words surrounded by double underscores, e.g. __NOTOC__, or keywords using parser function syntax
  • Variables: uppercase words surrounded by double braces, e.g. {{PAGENAME}} (thus resembling templates)
  • Parser functions: keywords (some beginning #) in double braces with parameters after a colon, e.g. {{#expr:2+2}}

Some magic words are case-insensitive, but not all. Whitespace is stripped from the start and end of keywords and parameters, as in template syntax.

Page-dependent magic words will affect or return data about the current page, even if the word is added through a transcluded template or included system message.

It is possible to substitute parser functions and variables in the same way that templates are substituted (using the subst: keyword). This causes their current value (as evaluated at the time of substitution) to be written into the wikitext.

Behavior switches

For documentation, refer to the Behavior Switches section of the MediaWiki page.

  • __NOTOC__ (can appear anywhere in the wikitext; suppresses the table of contents)
  • __FORCETOC__ (can appear anywhere in the wikitext; makes a table of contents appear in its normal position above the first header)
  • __TOC__ (places a table of contents at the word's position)
  • __NOEDITSECTION__ (hides the section "edit" links beside headings)
  • __NEWSECTIONLINK__ (adds a "+" link for adding a new section on a non-"Talk" page)
  • __NONEWSECTIONLINK__ (removes the "+" link on "Talk" pages)
  • __NOGALLERY__ (on a category page, replaces thumbnails with normal links)
  • __HIDDENCAT__ (on a category page, makes it a hidden category)
  • __INDEX__ (tells search engines to index the page)
  • __NOINDEX__ (tells search engines not to index the page)
  • {{DISPLAYTITLE:title}} (changes the displayed form of the page title)
  • {{DEFAULTSORT:sortkey}} (sets a default category sort key)

Variables

For documentation, refer to the Variables section of the MediaWiki page.

  • {{FULLPAGENAME}} (page title including namespace)
  • {{PAGENAME}} (page title excluding namespace)
  • {{BASEPAGENAME}} (page title excluding current subpage and namespace - effectively the parent page without the namespace.)
  • {{SUBPAGENAME}} (subpage part of title)
  • {{SUBJECTPAGENAME}} (associated non-talk page)
  • {{TALKPAGENAME}} (associated talk page)
  • {{NAMESPACE}} (namespace of current page)
  • {{SUBJECTSPACE}}, {{ARTICLESPACE}} (associated non-talk namespace)
  • {{TALKSPACE}} (associated talk namespace)
  • {{FULLPAGENAMEE}}, {{NAMESPACEE}} etc. (equivalents encoded for use in MediaWiki URLs)

The above can all take a parameter, to operate on a page other than the current page.

  • {{SITENAME}} (OPOSSEM)
  • {{SERVER}} (http://wiki.opossem.org)
  • {{SERVERNAME}} (wiki.opossem.org)
  • {{SCRIPTPATH}} (http://wiki.opossem.org)
  • {{CURRENTVERSION}} (current MediaWiki version)
  • {{REVISIONID}} (latest revision to current page)
  • {{REVISIONDAY}}, {{REVISIONDAY2}}, {{REVISIONMONTH}}, {{REVISIONYEAR}}, {{REVISIONTIMESTAMP}}, {{REVISIONUSER}} (date, time, editor at last edit)
  • {{CURRENTYEAR}}, {{CURRENTMONTH}}, {{CURRENTMONTHNAME}}, {{CURRENTMONTHABBREV}}, {{CURRENTDAY}}, {{CURRENTDAY2}}, {{CURRENTDOW}}, {{CURRENTDAYNAME}}, {{CURRENTTIME}}, {{CURRENTHOUR}}, {{CURRENTWEEK}}, {{CURRENTTIMESTAMP}} (current date/time variables)
  • {{LOCALYEAR}} etc. (as above, based on site's local time)
  • {{NUMBEROFPAGES}}, {{NUMBEROFARTICLES}}, {{NUMBEROFFILES}}, {{NUMBEROFEDITS}}, {{NUMBEROFVIEWS}}, {{NUMBEROFUSERS}}, {{NUMBEROFADMINS}}, {{NUMBEROFACTIVEUSERS}} (statistics on English Wikipedia; add :R to return numbers without commas)

Parser functions

Shortcut:
WP:PF

These are documented at the main documentation page unless otherwise stated.

Metadata

  • {{PAGESIZE:page name}} (size of page in bytes)
  • {{PROTECTIONLEVEL:action}} (protection level for given action on the current page)
  • {{PAGESINCATEGORY:categoryname}} (number of pages in the given category)
  • {{NUMBERINGROUP:groupname}} (number of users in a specific group)

Add |R to return numbers without commas.

Formatting

  • {{lc:string}} (convert to lower case)
  • {{lcfirst:string}} (convert first character to lower case)
  • {{uc:string}} (convert to upper case)
  • {{ucfirst:string}} (convert first character to upper case)
  • {{formatnum:unformatted num}} (format a number with comma separators; add |R to unformat a number)
  • {{#formatdate:date|format}} (formats a date according to user preferences; a default can be given as an optional case-sensitive second parameter for users without date preference; can convert a date from an existing format to any of dmy, mdy, ymd or ISO 8601 formats, with the user's preference overriding the specified format)
  • {{padleft:xyz|stringlength}}, {{padright:xyz|stringlength}} (pad with zeros to the right or left; an alternative padding string can be given as a third parameter; the alternative padding string may be truncated if its length does not evenly divide the required number of characters)
  • {{plural:n|is|are}} (produces alternative text according to whether n is greater than 1)
  • {{#time:format string|date/time object}} (for date/time formatting; also #timel for local time. Covered at the extension documentation page.)
  • {{gender:username|masculine|female|neutral}} (produces alternative text according to the gender specified by the given user in his/her preferences)

Paths

  • {{localurl:page name}}, {{localurl:page name|query string}} (relative path to the title)
  • {{fullurl:page name}}, {{fullurl:page name|query_string}} (absolute path to the title)
  • {{filepath:file name}} (absolute URL to a media file)
  • {{urlencode:string}} (input encoded for use in URLs)
  • {{anchorencode:string}} (input encoded for use in URL section anchors)
  • {{ns:n}} (name for the namespace with index n; use {{nse:}} for the equivalent encoded for MediaWiki URLs)
  • {{#rel2abs: path }} (converts a relative file path to absolute; see the extension documentation)
  • {{#titleparts: pagename | number of segments to return | first segment to return }} (splits title into parts; see the extension documentation)

Conditional expressions

These are covered at the extension documentation page. Some parameters are optional.

  • {{#expr: expression }} (evaluates the given expression; see Help:Calculation)
  • {{#if: test string | value if non-empty | value if empty }} (selects one of two values based on whether the test string is empty)
  • {{#ifeq: string 1 | string 2 | value if equal | value if unequal }} (selects one of two values based on whether the test strings are equal – numerically if applicable)
  • {{#iferror: test string | value if error | value if correct }} (selects value based on whether the test string generates a parser error)
  • {{#ifexpr: expression | value if true | value if false }} (selects value based on evaluation of expression)
  • {{#ifexist: page title | value if exists | value if doesn't exist }} (selects value depending on whether a page title exists)
  • {{#switch: test | case1 = value for case 1 | ... | default }} (provides alternatives based on the value of the test string)

For the use of these functions in tables, see Conditional tables.
