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

A "magic word" is a symbol which is 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:

  • an upper case word, preceded and followed by two underscores, e.g. __NOTOC__
  • an XML object, coded similar to HTML, 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.

Tags which are used on this page such as "[MW1.5+]" indicate the version that first supported the magic word. "XYZ" indicates user input, which is used in the example.

Magic words between double underscores

Word Explanation
__NOEDITSECTION__ Hides the edit links beside headings.
__NEWSECTIONLINK__ [MW1.7+] Gives a "+"-link next to the edit-tab to make a new section on a non-talk page.
__NOCONTENTCONVERT__
__NOCC__
Don't perform the content language conversion (character and phase) in article display; for example, Chinese zh with zh_cn, zh_tw, zh_sg, zh_hk.
__NOGALLERY__ [MW1.7+] This magic word allows images in category pages to be displayed as inline links instead of gallery.
__NOTITLECONVERT__
__NOTC__
Like __NOCC__ but affecting article title only.
__END__ Allows for trailing whitespace to be included in the page save (does not seem to work anymore).
__START__ This magic word has no effect but an ID in MagicWord.php (MAG_START).


XML-style tags

nowiki: <nowiki>...</nowiki>, disables expansion/interpretation of templates, link syntax, formatting syntax, etc.: <nowiki>'''[[{{tc}}]]'''</nowiki> gives '''[[{{tc}}]]'''

pre: <pre>...</pre>, ditto, also for multiple lines; it is rendered with a new paragraph at the start and end: a<pre>'''[[{{tc}}]]'''</pre>b gives a

'''[[{{tc}}]]'''

b

math: <math>...</math>, e.g. <math>\sqrt{a^2+b^2}</math> gives \(\sqrt{a^2+b^2}\); see Help:Displaying a formula

hiero: <hiero>...</hiero>, e.g. <hiero>A1</hiero> gives:

A1

Variables

For details see Help:Variable

Time

The time in UTC. Note that if the page was displayed by the same user and has not changed (has not been edited) since the last time it was displayed, it is possible that the page may be cached (by the user's browser) and the displayed time or date may not change. Also, if a heavily used page, rather than freshly rendered by the software each time it is generated, is instead being retrieved from a caching system (such as the main page on Wikipedia) the date or time may not change from the last time the page was originally retrieved by the caching hardware or software.

Returns the name of a given namespace number.
{{localurl:x y @}}
{{localurle:x y @}}
{{localurl:a|b=c}}
{{localurl:Wikipedia:Category}}

[MW1.5+] Returns the full URL of a given page. Optional query parameter as for localurl:.


Formatting

Word Example Explanation
{{#language:}} {{#language:da}} = dansk [MW1.7+] Native name of language code.
{{lc:}} {{lc:AbC dEf}} = abc def [MW1.5+] LowerCase
{{lcfirst:}} {{lcfirst:Ab Cd}} = ab Cd [MW1.5+] LC first char.
{{uc:}} {{uc:aBc DeF}} = ABC DEF [MW1.5+] UpperCase
{{ucfirst:}} {{ucfirst:aB cD}} = AB cD [MW1.5+] UC first char.
{{formatnum:}} {{formatnum:-299792458.56789}} = -299,792,458.56789 [MW1.7+] Add decimal separators according to the wiki's default locale. Leading minus and plus are recognized.
{{padleft:}}




{{padright:}}

{{padleft:7|3|0}} = 007

{{padleft:0|3|0}} = 000 (bug)

{{padleft:bcd|6|a}} = aaabcd

{{padleft:café|8|-}} =
café(<==Bug effect)
{{padleft:cafe|8|-}} =
cafe

{{padleft:bcd|6|{{!}}}} = |||bcd

{{padright:bcd|6|a}} = bcdaaa
{{padright:0|6|a}} = 0aaaaa (bug)


First case is, for example, applicable to years in a category... giving an ordered year to sort by pipetricks order, or any such ordering where left extended zeros allow a proper sorting.

[MW1.8+] Pads a string with a character to the specified width. Note that there's a little bug that interprets non-US-ASCII characters as two, instead of one character (see the difference in café and cafe in the examples.)

It does not seem possible to use padleft and padright for padding with characters with a multi-character code, such as &nbsp;, which would be useful with padleft for sorting tables with Javascript.

Padding "0" does not work, it returns the same. This seems to be a bug.[1]


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}} Shorthand for {{MediaWiki:xyz}}, 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 unevaluated wikitext is rendered. See msgnw.
{{raw:xyz}} [MW1.6+] Equivalent to {{msg:xyz}} above[2].
{{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 [[Image:title.ext|modifier|...|modifier]] links. Some are mutually exclusive, and then the last specified wins.

Size

The last unrecognized modifier is used as caption for framed images or together with thumbnails. It's also used as description alt=text.

Word Usage Explanation
framed
frame
enframed
[[Image: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 [[Image:Mediawiki.png|border]] Shows a 1px border around the image.
thumbnail
thumb
[[Image:Mediawiki.png|thumbnail]] Modifies image size, sets it to dependant on user's favourite thumbnail size in their preferences, or on the given width parameter (see below).
thumb=xyz [[Image:Mediawiki.png|thumb=Wiki.png]] Manualthumb: instead of displaying an automatically-sized thumbnail for Mediawiki.png, display the image Wiki.png.
width px
100x200px
[[Image:Mediawiki.png|40px]]
[[Image: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 it's 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:- can stop floating. For inline images only modifier px (see above) is supported.

Word Usage Explanation
right [[Image:Mediawiki.png|right]] Modifies position, floats the image to the right.
left [[Image:Mediawiki.png|left]] Modifies position, floats the image to the left.
none [[Image:Mediawiki.png|none]] Explicitly states that the image should not float.
center
centre
[[Image:Mediawiki.png|center]] Modifies position, like none but centered.


Miscellany

Word Example Explanation
{{DISPLAYTITLE:xyz}} default disabled [MW 1.7+] Set the page's title [5], see Template:H:mwg.
{{DIRMARK}}
{{DIRECTIONMARK}}

[MW1.7+] u+200E left to right or u+200D right to left mark
{{CONTENTLANGUAGE}} en [MW1.7+] code of the site's default interface language (Template:H:mwg)
{{DEFAULTSORT:xyz}} {{DEFAULTSORT:xyz}} [MW1.10+] Sets a default category sort key for the whole current page (also applying for category tags before this tag)[3].
#REDIRECT #REDIRECT [[target]]
at top of source page
Creates a redirect to another page.


Language-dependent word conversions

Word Example Explanation
{{ CURRENTMONTHNAMEGEN }} October Genitive form of month name used for Czech, Polish, Ukrainian[6]
{{grammar:case | word }} {{grammar:7sg|Wikipedie}}
on cs: is Wikipedií.
Derived word forms in inflected languages like Czech [7]
{{plural:count |form1 |form2 }}
{{plural:count |1st | 2nd | 3rd }}
{{plural: 2 | is | are }}
outputs are
{{plural: 0 | this | these }}
outputs these
count 1 yields form1 (singular), plural transformations are used for languages like Russian [8] based on "count mod 10".


"Grammar" and "Plural" are language-dependent functions, defined in [9], [10], 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 (oddly, first option is 1, 21, 31,.., 91, 101, 121, .., second is 2, 3, 4, 22, 23, 24, 31, 32, 33, 41,.., 94, 102, 103, 104,.., 122, 123,.., and else the third).

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. Template:Msg, where it uses interface language instead of site language.

  1. ^ Function pad in includes/CoreParserFunctions.php puts, oddly, the $string itself as a condition for the padding. To be reported as bug.
