Help:Magic words

From RobotX
Jump to navigation Jump to search

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 Manual:Magic words .

There are three general types of magic words:

Variables and parser functions can use 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.

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 Minerva skin.

Word Description Versions
Table of contents
__NOTOC__ Hides the table of contents (TOC).
__FORCETOC__ Forces the table of contents to appear at its normal position (before the first header, overriding __NOTOC__).
__TOC__ Places a table of contents at the word's current position (overriding __NOTOC__). If this is used multiple times, the table of contents will appear at the first word's position.
Editing
__NOEDITSECTION__ 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 here.
__NEWSECTIONLINK__ Adding a section to the end]]).
1.7
__NONEWSECTIONLINK__ Removes the link beside the "Edit" tab on pages in talk namespaces.
1.15
r47522
Categories
__NOGALLERY__ Used on a category page, replaces thumbnails in the category view with normal links.
1.7
__HIDDENCAT__ Used on a category page, hides the category from the lists of categories in its members and parent categories (there is an option in the [[<tvar|help-preferences>Special:MyLanguage/Help:Preferences|user preferences]] to show them).
1.13
__EXPECTUNUSEDCATEGORY__ Used on a category page, removes the category from Special:UnusedCategories .
1.33
Language conversion
__NOCONTENTCONVERT__
__NOCC__
On wikis with language variants, don't perform any content language conversion (character and phase) in article display; for example, only show Chinese (zh) instead of variants like zh_cn, zh_tw, zh_sg, or zh_hk.
__NOTITLECONVERT__
__NOTC__
On wikis with language variants, don't perform language conversion on the title (all other content is converted).
Other
__START__ No effect. Was used to point where database message starts after comment that should not be transcluded. Removed in r1695 and completely removed in r24784
1.10
r1610
__END__ Explicitly marks the end of the article, to prevent MediaWiki from removing trailing whitespace. Removed in 19213.
1.1 – 1.8
__INDEX__ manual-wg-bot-policy>$wgArticleRobotPolicies but not robots.txt). It obeys <tvar|manual-wg-exempt-from-bot>$wgExemptFromUserRobotsControl variable.
1.14
__NOINDEX__ manual-wg-exempt-from-bot>$wgExemptFromUserRobotsControl variable.
1.14
r37973
__STATICREDIRECT__ fixDoubleRedirects>Update any redirects that point to the original title" (which requires [[<tvar|var>Special:MyLanguage/Manual:$wgFixDoubleRedirects|$wgFixDoubleRedirects]]).
1.13
r37928
From Extensions
Extension Word Description Versions
GlobalUserPage __NOGLOBAL__ Disables the global user page. If present on the central user page, will prevent it from being displayed on remote wikis, and it also determines whether a link to a user page on remote wiki should be red or blue.
1.28
Disambiguator __DISAMBIG__ Identifies a disambiguation page.
1.21

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 "[expensive]" 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 Template:PAGENAME you would need to write <tvar|code>{{Template:PAGENAME<tvar|code-end>}}). In some cases, adding parameters will force the parser to invoke a template; for example, <tvar|tpl-currentdayname-code>{{CURRENTDAYNAME|x}} transcludes <tvar|tpl-currentdayname-result>Template:CURRENTDAYNAME, not the variable.

Date and time

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.

The use of those variables cause pages to be cached for a more limited number of seconds. This is configured in <tvar|MagicWordFactory>MagicWordFactory.

The date and time magic words are formatted in the wiki content language. Since 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>{{NUMBEROFPAGES}} → <tvar|nop-result>5,112 and <tvar|nop-r-code>{{NUMBEROFPAGES:R}} → <tvar|nop-r-result>5112).

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

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

Page names

Variable For current page Description Versions
{{FULLPAGENAME}} Help:Magic words Namespace and full page title (including all subpage levels).
1.6
{{PAGENAME}} Magic words Full page title (including all subpage levels) without the namespace.
{{BASEPAGENAME}} Magic words

Page title of the page in the immediately superior [[<tvar|help-subpages>Special:MyLanguage/Help:Subpages|subpage]] level without the namespace ("Title/foo" on "Help:Title/foo/bar").


For more complex splitting, use <tvar|help-ext-pf-titleparts>{{#titleparts:}} from the [[<tvar|help-ext-pf>Special:MyLanguage/Help:Extension:ParserFunctions|ParserFunctions extension]].

1.7
{{SUBPAGENAME}} Magic words The [[<tvar|help-subpages>Special:MyLanguage/Help:Subpages|subpage]] title ("bar" on "Help:Title/foo/bar"). If no subpage exists the value of <tvar|code>{{PAGENAME}} is returned.
1.6
{{SUBJECTPAGENAME}}
{{ARTICLEPAGENAME}}
Help:Magic words
Help:Magic words
Full page name of the associated subject (e.g. article or file). Useful on talk pages.
1.7
{{TALKPAGENAME}} Help talk:Magic words Full page name of the associated talk page.
1.7
{{ROOTPAGENAME}} Magic words foo>Title on page <tvar|baz>Help:Title/Foo/Bar
1.22
None of these are affected by changes to the display title using {{DISPLAYTITLE:xxxx}}; the values returned are the original page title.


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


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

  • {{PAGENAME:Template:Main Page}}Main Page

URL encoded page names

The following are equivalents encoded for use in MediaWiki URLs (i.e. spaces replaced with underscores and some characters HTML escaped using numeric character encoding):

  • {{FULLPAGENAMEE}}
  • {{PAGENAMEE}}
  • {{BASEPAGENAMEE}}
  • {{SUBPAGENAMEE}}
  • {{SUBJECTPAGENAMEE}}
  • {{ARTICLEPAGENAMEE}}
  • {{TALKPAGENAMEE}}
  • {{ROOTPAGENAMEE}}


Note that <tvar|pagename>{{PAGENAME:...}}, <tvar|pagenamee>{{PAGENAMEE:...}} and <tvar|uec>{{urlencode:...}} have distinct implementations. See [[<tvar|manual-pagename-encoding>Special:MyLanguage/Manual:PAGENAMEE encoding|Manual:PAGENAMEE encoding]] for details.

As of 1.15+, these can take a full-page-name parameter and will return the requested namespace associated with that page, instead of with the current page:


  • {{NAMESPACENUMBER:MediaWiki}}0
  • {{NAMESPACE:MediaWiki}} (Pages in main space will return empty)
  • {{NAMESPACE:Template:Main Page}}Template
  • {{SUBJECTSPACE:Template:Main Page}}Template
  • {{ARTICLESPACE:Template:Main Page}}Template
  • {{TALKSPACE:Template:Main Page}}Template talk
Parameter must not be a namespace name:
  • {{SUBJECTSPACE:Help talk}}  (Empty)

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 <tvar|ext-pf>Extension:ParserFunctions . For those see <tvar|help-ext-pf>Help:Extension:ParserFunctions .

  • When the given param is equal to the current title of the parser, the parser function will yield the previous versions on preview and on substitution, that includes empty strings when used on page creation but using the values from the current version for page view, including viewing old revisions. In this case it is a non-expensive parser function.

Namespaces

<tvar|ns>{{ns:}} 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>{{ns:6}}, <tvar|ns-file>{{ns:File}}, and <tvar|ns-img>{{ns:Image}} (an old name for the File namespace) all return "File". On a wiki where the content language is French, <tvar|ns-file-de>{{ns:Fichier}} is also valid, but <tvar|ns-file-incorrect>{{ns:Datei}} (the localisation of "File" in German) is not.


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

    • {{formatnum:987654321.654321}}
      → 987,654,321.654321
    • {{formatnum:987,654,321.654321|R}}
      → 987654321.654321
  • Advanced:
    • {{formatnum:{{formatnum:987654321.654321}}|R}}
      → 987654321.654321 (on any locale)
    • {{formatnum:00001}}
      → 00,001
    • {{formatnum:987654321.654321 |NOSEP}}
      → 987654321.654321
    • Examples with বাংলা locale:
      • {{formatnum:987654321.654321}}
        → ৯৮,৭৬,৫৪,৩২১.৬৫৪৩২১
      • {{formatnum:987654321.654321 |NOSEP}}
        → ৯৮৭৬৫৪৩২১.৬৫৪৩২১
      • {{formatnum:৯৮,৭৬,৫৪,৩২১.৬৫৪৩২১ |R}}
        → 987654321.654321

Unsupported: 

{{formatnum:{{formatnum:987.654.321}}}}
→ 987 654 321 (e.g. with Italian locale)


Examples of wrong input (unreliable output), with or without |R: 

{{formatnum:987,654.321|R}} (the least broken)
{{formatnum:987.654,321|R}}
{{formatnum:987 654,321|R}}
{{formatnum:987&nbsp;654,321|R}}

Takes an unformatted number (Arabic, no group separators and . 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.
The |R 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.

The NOSEP ("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 Hindu–Arabic numeral system. NOSEP can also prevent non-standard digit groupings you wouldn't expect.




If you really need to format (according the wiki's locale) a number in unknown input format, you could try and use formatnum 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.


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: mdy, dmy, ymd, ISO 8601 (all case sensitive). If only the month and day are given, only mdy and dmy 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.

(first character of the string) 

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. {{padleft:44|3|0}} produces 044. 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.


Bug (fixed in r45734): multibyte characters are interpreted as two characters, which can skew width. These also cannot be used as padding characters.

Identical to padleft but adds padding characters to the right side.

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>Extension:Translate .


The usage of these magic words can be very complex, and the documentation is currently incomplete; there's some more info on PLURAL, GRAMMAR, GENDER.

Outputs the singular form (second parameter) if the absolute value of the first parameter is an expression equalling one; the plural form (third parameter) otherwise. Its functioning is [[<tvar|meta-help-magicwords>m:Special:MyLanguage/Help:Magic_words#Language-dependent_word_conversions|language-dependent]].
Some language codes (ab, av, ba, bxr, ce, crh_cyrl, cv, inh, koi, krc, kv, lbe, lez, mhr, mrj, myv, ru, tt_cyrl, tyv, udm, xal) used 3 plural forms (updated 01.2014):
  • Form 1: 1, 21, 31, 41, 51, 61, 71, 81, 101, 1001, …
  • Form 2: 0, 5, 6, 7, 8, …, 18, 19, 100, 1000, 10000, 100000, 1000000, …
  • Form 3: 2, 3, 4, 22, 23, 24, 32, 33, 34, 42, 43, 44, 52, 53, 54, 62, 102, 1002, …
{{grammar:N|noun}} Outputs the correct inflected form of the given word described by the inflection code after the colon ([[<tvar|meta-help-magicwords>m:Special:MyLanguage/Help:Magic_words#Language-dependent_word_conversions|language-dependent]]). Grammar transformations are used for inflected languages like Polish. See also <tvar|manual-wg-grammarform>$wgGrammarForms.

{{gender:username|text for every gender}}

{{gender:Username|male text|female text|text for unspecified}}
{{gender:|male text|female text|text for unspecified}}
{{gender:.|male text|female text|text for unspecified}}

(Depends on the named user's gender)

A switch for the gender set in Special:Preferences.
Note: The first example is basically a no-op
Note: If 3rd parameter is omitted and user hasn't defined their gender, then text if user is male is returned.
A blank username field (<tvar|gender>{{gender:|) means the current user, but can be used only in interface messages (MediaWiki namespace).
A dot username (.) means the default user gender on this wiki.

{{int: message name}} {{int:edit}}Edit
(Depends on user language; try: frja)

Internationalizes (translates) the given interface (MediaWiki namespace) message into the user language. For msgnw and other transclusion magic words, see the [[<tvar|sec>#Transclusion modifiers|Transclusion modifiers]] section. Note that this can damage / confuse cache consistency in MediaWiki 1.17 and earlier, see T16404.

{{int:editsectionhint|MediaWiki}} {{int:editsectionhint|MediaWiki}}Edit section: MediaWiki You may also use parameters with translations.
Parameters are designated in messages with: $1, $2, $3, etc.
For example, here is the message for editsectionhint: Edit section: $1
In this example, MediaWiki replaces $1.

Transclusion modifiers

{{Page name|optional params}} usually transcludes another page, by default from the Template:namespace.


These magic words modify that behavior.
