Help:Magic words

DCCWiki, a community DCC encyclopedia.
Jump to: navigation, 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.

There are three general types of magic words:

  • Behavior switches: these are usually written as uppercase words surrounded by double underscores, e.g. __FOO__.
  • Variables: these are uppercase words surrounded by double braces, e.g. {{FOO}}. As such, they look a lot like templates.
  • Parser functions: these take parameters and are either of the form {{foo:...}} or {{#foo:...}}, e.g. {{#invoke:}}.

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 and can often be used to specify desired omissions and inclusions in the content.

Word Description
Table of contents
{{notoc}} Hides the table of contents (TOC).
__FORCETOC__ Forces the table of contents to appear at its normal position (this will not override {{notoc}}).
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.
__NEWSECTIONLINK__ Adds a link beside the "⧼vector-view-edit⧽" tab for adding a new section on a non-talk page (see Adding a section to the end).
__NONEWSECTIONLINK__ Removes the link beside the "⧼vector-view-edit⧽" tab on pages in talk namespaces.
Categories
__NOGALLERY__ Used on a category page, replaces thumbnails in the category view with normal links.
__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 user preferences to show them).
__EXPECTUNUSEDCATEGORY__ Used on a category page, removes the category from Special:UnusedCategories.
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
__INDEX__ Tell search engines to index the page (overrides Template:Mediawiki but not robots.txt). It obeys Template:Mediawiki variable.
__NOINDEX__ Tell search engines not to index the page (i.e. do not list in search engines' results). It obeys Template:Mediawiki variable.
__STATICREDIRECT__ On redirect pages, don't allow MediaWiki to automatically update the link when someone moves a page and checks "Update any redirects that point to the original title".

Variables

Variables return information about the current page, wiki, or date. Their syntax is similar to 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 {{Template:PAGENAME}}). In some cases, adding parameters will force the parser to invoke a template; for example, {{CURRENTDAYNAME|x}} transcludes 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 MagicWordFactory.

The date and time magic words are formatted in the wiki content language.

Variable Output Description
Year
{{CURRENTYEAR}} 2024 Year

{{SERVER}} https://dccwiki.com Domain URL (Template:Mediawiki).
{{SERVERNAME}} dccwiki.com Subdomain and domain name (no longer dependent on Template:Mediawiki as of version 1.17).
{{DIRMARK}}

{{DIRECTIONMARK}}

‎

‎

Outputs a Unicode directional mark that matches the wiki's default language's direction (‎ on left-to-right wikis, ‏ on right-to-left wikis), useful in text with multi-directional text..
{{SCRIPTPATH}} /w Relative script path (Template:Mediawiki).
{{STYLEPATH}} /skins Relative style path (Template:Mediawiki).
{{CURRENTVERSION}} 1.39.6 The wiki's MediaWiki version.
{{CONTENTLANGUAGE}}

{{CONTENTLANG}}

en

en

The wiki's default interface language (Template:Mediawiki).
Page
{{PAGEID}} 6571 Returns the page identifier.
{{PAGELANGUAGE}}

{{#language:{{PAGELANGUAGE}}}}

en

English

Returns the language of the current page. The language code that this variable returns can be converted to a language name using {{#language:...}}.
<translate><!--T:1--> Translated unit. Language: {{TRANSLATIONLANGUAGE}}.</translate>

<translate><!--T:2--> Not translated unit. Language: {{TRANSLATIONLANGUAGE}}.</translate>

Translated unit. Language: Template:TRANSLATIONLANGUAGE.

Not translated unit. Language: en.

Must be used in a translated page, inside <translate> tags. Returns the language code of the current translation unit. In a translation page, if the unit has been translated, then it returns translation language. Else, it returns source language. The language code that this variable returns can be converted to a language name using {{#language:...}}. Should only be used by translation admins.
{{PROTECTIONLEVEL:action}} Outputs the protection level (e.g. "autoconfirmed", "sysop") for a given action (e.g. "edit", "move") on the current page. Returns an empty string if not protected.
{{PROTECTIONEXPIRY:action}} Outputs the protection expiry (e.g. "20160418155030", "infinity") for a given action (e.g. "edit", "move") on the current page. Returns "infinity" if not protected.
{{CASCADINGSOURCES}} [Expensive] Returns the sources of any cascading protection acting on the current page. Pages will not return their own title unless they transclude themselves.
Latest revision to current page
{{REVISIONID}} 24139 Unique revision ID. It is empty in preview, thus one can show an error message only in preview. May be disabled at time of high server load.
{{REVISIONDAY}} 7 Day edit was made (unpadded number).
{{REVISIONDAY2}} 07 Day edit was made (zero-padded number).
{{REVISIONMONTH}} 04 Month edit was made (zero-padded number).
{{REVISIONMONTH1}} 4 Month edit was made (unpadded number).
{{REVISIONYEAR}} 2021 Year edit was made.
{{REVISIONTIMESTAMP}} 20210407092233 Timestamp as of time of edit.
{{REVISIONUSER}} TazzyTazzy The username of the user who made the most recent edit to the page, or the current user when previewing an edit.
{{REVISIONSIZE}} 52815 The size (bytes of wikitext) of the current revision of this page
Affects page content
{{DISPLAYTITLE:title}}
{{DISPLAYTITLE:title|noerror}}
{{DISPLAYTITLE:title|noreplace}} 		Format the current page's title header. The value must be equivalent to the default title: only capitalization changes to certain parts of the title (not all) and replacing spaces with underscores are allowed (this can be changed with Template:Mediawiki). It can be disabled or enabled by Template:Mediawiki; disabled by default before 1.10+, enabled by default thereafter.

It can take a second argument of noerror or noreplace to suppress error messages when multiple displaytitles are used on one page or to make this displaytitle do nothing if a displaytitle was already specified earlier in the page.

(for noerror and noreplace)

{{DEFAULTSORT:sortkey}}
{{DEFAULTSORTKEY:sortkey}}
{{DEFAULTCATEGORYSORT:sortkey}}
{{DEFAULTSORT:sortkey|noerror}}
{{DEFAULTSORT:sortkey|noreplace}} 		Used for categorizing pages, sets a default category sort key. For example if you put {{DEFAULTSORT:Smith, John}} at the end of John Smith, the page would be sorted under "S" by default in categories. It can take a second argument of noerror or noreplace to suppress error messages when multiple defaultsortkeys are used on one page or to make this defaultsort do nothing if a defaultsort was already specified earlier in the page.

(for noerror and noreplace)

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, {{NUMBEROFPAGES}} → 4,789 and {{NUMBEROFPAGES:R}} → 4789).

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

The number magic words are formatted in the wiki content language.

Variable Output Description
{{NUMBEROFPAGES}} 4,789 Number of wiki pages.
{{NUMBEROFARTICLES}} 1,135 Number of pages in content namespaces that qualify as articles.
{{NUMBEROFFILES}} 946 Number of uploaded files.
{{NUMBEROFEDITS}} 30,387 Number of wiki edits.
{{NUMBEROFUSERS}} 305 Number of registered users.
{{NUMBEROFADMINS}} 3 Number of users in the sysop group.
{{NUMBEROFACTIVEUSERS}} 4 Number of active users, based on the criteria used in Special:Statistics.
{{PAGESINCATEGORY:categoryname}}
{{PAGESINCAT:categoryname}} 		18
18 		[Expensive] Number of pages (including subcategories and files) in the given category. (Category:Help used for demonstration)
{{PAGESINCATEGORY:categoryname|all}}
{{PAGESINCATEGORY:categoryname|pages}}
{{PAGESINCATEGORY:categoryname|subcats}}
{{PAGESINCATEGORY:categoryname|files}} 		18
18
0
0 		[Expensive]

Respectively, the number of

  • all pages
  • ordinary pages (excluding subcategories and files)
  • subcategories or
  • files

in the given category. (Category:Help used for demonstration)

{{NUMBERINGROUP:groupname}}
{{NUMINGROUP:groupname}} 		3
3 		Number of users in a specific group. ({{NUMBERINGROUP:bureaucrat}} used for demonstration)
{{PAGESINNS:index}}
{{PAGESINNAMESPACE:index}} 		Not enabled [Expensive] Number of pages in the given namespace (replace index with the relevant namespace index). For instance, {{PAGESINNAMESPACE:14}} will output the number of category pages. {{PAGESINNS:0}} differs from {{NUMBEROFARTICLES}} in that the former includes redirects and disambiguation pages.

Page names

Variable For current page Description
{{FULLPAGENAME}} Help:Magic words Namespace and full page title (including all subpage levels).
{{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 subpage level without the namespace. Would return Title/Foo on page Help:Title/Foo/Bar.
{{ROOTPAGENAME}} Magic words Name of the root of the current page. Would return Title on page Help:Title/Foo/Bar.
{{SUBPAGENAME}} Magic words The subpage title. Would return Bar on page Help:Title/Foo/Bar.


If no subpage exists the value of {{PAGENAME}} is returned.

{{SUBJECTPAGENAME}}
{{ARTICLEPAGENAME}} 		Help:Magic words
Help:Magic words 		Full page name of the associated subject (e.g. article or file). Useful on talk pages.
{{TALKPAGENAME}} Help talk:Magic words Full page name of the associated talk page.


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

The {{BASEPAGENAME}} and {{SUBPAGENAME}} magic words only work in namespaces that have subpages enabled. See Template:Mediawiki for information on enabling subpages.

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
If the page title contains any parts that are "." or "..", the magic word fails returning nothing.
{{PAGENAME:one/./three}} → '. Nothing is returned.
Page titles containing certain characters, such as apostrophes ' or asterisks *, may produce unexpected results when handled with these magic words, e.g. {{PAGESINCATEGORY:{{PAGENAME}}}}.

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 {{PAGENAME:...}}, {{PAGENAMEE:...}} and {{urlencode:...}} have distinct implementations.


Namespaces

Variable Output Description
{{NAMESPACE}} Help Name of the page's namespace
{{NAMESPACENUMBER}} 12 ID of the page's namespace
{{SUBJECTSPACE}}
{{ARTICLESPACE}} 		Help
Help 		Name of the associated content namespace
{{TALKSPACE}} Help talk Name of the associated talk namespace


The following are equivalents encoded for use in MediaWiki URLs (spaces replaced with underscores and some characters percent-encoded):


  • {{NAMESPACEE}}
  • {{SUBJECTSPACEE}}
  • {{ARTICLESPACEE}}
  • {{TALKSPACEE}}


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)

Other

Variable Output Description
{{!}} | Used to include a pipe character as part of a template argument or table cell contents. Before this was added as a magic word, many wikis implemented this by creating Template:! with | as the content.

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.


Technical metadata of another page

Parser function Output
(for page MediaWiki) 		Description
{{PAGEID: page name }} 1884 [Expensive] Returns the page identifier of the specified page*.
{{PAGESIZE:page name}}
{{PAGESIZE: page name |R}} 		52,815
52815 		[Expensive] Returns the byte size of the specified page. Use "|R" to get raw (unformatted) numbers.
page name}} [Expensive] Outputs the protection level (e.g. "autoconfirmed", "sysop") for a given action (e.g. "edit", "move") on the specified page. Returns an empty string if not protected.
{{PROTECTIONEXPIRY:

action | page name}}

infinity [Expensive] Outputs the protection expiry (e.g. "20160418155030", "infinity") for a given action (e.g. "edit", "move") on the specified page. Returns "infinity" if not protected.
{{CASCADINGSOURCES: page name}} [Expensive] Returns the sources of any cascading protection acting on the specified page. Pages will not return their own title unless they transclude themselves.
{{REVISIONID: page name }} 3090 [Expensive] Unique revision ID of the last revision on the specified page*.
{{REVISIONDAY: page name }} 24 [Expensive] Day of edit from the last revision of the specified page* (unpadded number).
{{REVISIONDAY2: page name }} 24 [Expensive] Day of edit from the last revision of the specified page* (zero-padded number).
{{REVISIONMONTH: page name }} 01 [Expensive] Month of edit from the last revision of the specified page* (zero-padded number).
{{REVISIONMONTH1: page name }} 1 [Expensive] Month of edit from the last revision of the specified page* (unpadded number).
{{REVISIONYEAR: page name }} 2006 [Expensive] Year of edit from the last revision of the specified page*.
{{REVISIONTIMESTAMP: page name }} 20060124031615 [Expensive] Timestamp as of time of edit on the specified page*.
{{REVISIONUSER: page name }} TazzyTazzy [Expensive] The username from the last revision on the specified page*.
  • 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.

{{filepath:Wiki.png|nowiki}}
→
{{filepath:Example.svg|300}}
→ https://upload.wikimedia.org/wikipedia/commons/thumb/8/84/Example.svg/300px-Example.svg.png

The parameter nowiki usually removes the link around the filepath (which can't be seen in this example).

A protocol-relative path to the full size or thumbnail of a media file.
{{urlencode:string}} or
{{urlencode:string|QUERY}}
{{urlencode:string|WIKI}}

{{urlencode:x:y/z á é|PATH}}
→ x%3Ay%2Fz%20%C3%A1%20%C3%A9

Note that the default changed from |WIKI to |QUERY in 1.17; this may break templates that rely on this function.

The input encoded for use in URLs.
{{anchorencode:string}} {{anchorencode:x y z á é}}
→ x_y_z_á_é 		The input encoded for use in URL section anchors (after the “#” symbol in a URL).

Namespaces

{{ns:}} returns the current localized name for the namespace with that index, canonical name, or local alias. Thus {{ns:6}}, {{ns:File}}, and {{ns:Image}} (an old name for the File namespace) all return "File". On a wiki where the content language is French, {{ns:Fichier}} is also valid, but {{ns:Datei}} (the localisation of "File" in German) is not.

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

  • Simple:
    • {{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)

        → ৯৮,৭৬,৫৪,৩২১.৬৫৪৩২১
      • {{formatnum:987654321.654321 |NOSEP}}

      • {{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 don't input numbers in the exact format required, don't expect any reliable output, especially on non-English wikis.


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.

{{#dateformat:25 dec 2009|ymd}}

→ December 25 (your pref), DecEmber 25 (default)
Note: In the examples above, "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.
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).
{{lc:string}} {{lc:DATA CENTER}} → data center The lowercase input.
{{lcfirst:string}} {{lcfirst:DATA center}} → dATA center The input with the very first character lowercase.
{{uc:string}} {{uc:text transform}} → TEXT TRANSFORM The uppercase input.
{{ucfirst:string}} {{ucfirst:text tRAnSFORM}} → Text tRAnSFORM The input with the very first character uppercase.
{{padleft:xyz|stringlength}}

{{padleft:xyz|strlen|char}}
{{padleft:xyz|strlen|string}}

{{padleft:xyz|5}} → 00xyz

{{padleft:xyz|5|_}} → __xyz
{{padleft:xyz|5|abc}} → abxyz
{{padleft:xyz|2}} → xyz
{{padleft:|1|xyz}} → x (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.

{{padright:xyz|stringlength}}
{{padright:xyz|strlen|char}}
{{padright:xyz|strlen|string}} 		{{padright:xyz|5}} → xyz00

{{padright:xyz|5|_}} → xyz__
{{padright:xyz|5|abc}} → xyzab
{{padright:xyz|2}} → xyz
{{padright:|1|xyz}} → x

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


Transclusion modifiers

{{Page name|optional params}} usually transcludes another page, by default from the Template:namespace. These magic words modify that behavior.

Usage Description
{{:xyz}} 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, {{:UTC}} (vs. {{UTC}}) to include the text of the main namespace article UTC rather than Template:UTC.
{{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 Template:Red link doesn't exist. See also Help:System message.
{{msg:xyz}}
{{raw: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.
{{raw:xyz}} If $wgEnableScaryTranscluding is enabled, and this is an interwiki transclusion, include the raw wikitext instead of the html from the foreign wiki.
{{msgnw:xyz}} The unexpanded wikitext is rendered (more or less, for details see Help:Templates#Usage).
{{subst:xyz}} In the wikitext, the tag is substituted by the content (single-level evaluation only), see Help:Templates#Usage.
{{safesubst:xyz}} See Help:Templates#Usage.

Alias for XML-style MediaWiki parser tags or extension tags. It allows a pre-save transform of wiki code within tags before the tag is processed. It also prevents parsing of tags in conditional paths that aren't executed (like in #if statements). Content between tags is passed as the first parameter, and any attributes for the tags can be passed as subsequent parameters. This example:


<tagname attribute1="value1"
attribute2="value2">Your content goes here</tagname>

…can be rewritten like this:

{{#tag:tagname|Your content goes here|attribute1=value1|attribute2=value2}}


You must write {{#tag:tagname||attribute1=value1|attribute2=value2}} to pass an empty content. No leading or trailing space of the text content are permitted between the pipe characters || before attribute1.
