 | This page is a how-to guide detailing a practice or process on the English Wikipedia. |
Magic words (including parser functions, variables and behavior switches) are features of wiki markup that give instructions to Wikipedia's underlying MediaWiki software. For example, magic words can suppress or position the table of contents, disable indexing by external search engines, and produce output dynamically based on the current page or on user-defined conditional logic. Some of these features are especially useful for templates.
This page is a quick reference for magic words. For more information, refer to the main MediaWiki documentation:
- mw:Help:Magic words: All standard magic words, including the "standard" parser functions.
- mw:Help:Extension:ParserFunctions: Additional parser functions, including conditional expressions.
General information
[????????]In general, there are three types of magic words
- Behavior switches: often appear in double underscores, all uppercase, e.g.,
__NOTOC__. They will change the behavior of a page, rather than return a value. - Parser functions: all in lowercase. A parser function will be followed by colon and pipe-separated parameters, e.g.,
{{#ifexpr:Y|Yes|No}}, wrapped in double braces. They will take a value and return a value. - Variables: these are all uppercase, e.g.,
{{PAGENAME}}. A variable will be wrapped in double braces and will return a value in its place.
The software generally interprets magic words in the following way.
- Magic words are case sensitive.
- White space is generously allowed for readability. It will be stripped from the start and end of their keywords and parameters (as is also done inside templates).
- They can be transcluded, even variables "about the current page". This is ensured by the parsing order.
- Instead of magically transforming into HTML instructions,
<nowiki>tags remove this magic so a magic word can itself be displayed (documented), e.g.<nowiki>{{#magic:}}</nowiki>or{{#magic:<nowiki />}}.
Magic words compared to templates:
- As with templates, magic words can be transcluded and substituted.
- The names of magic words are purposely chosen to be unlike the names of templates, and vice versa. Many parser function names will begin with a
#(pound), but template names will not start with a#, and probably not end in a:(colon), or be all-uppercase. - The first parameter's syntax differs. In
{{#magic: p1 | p2 | p3}}, the name is#magicand it is followed by an unspaced:and a required input parameter,p1. With a template,p1is optional and it is preceded by a|(pipe) instead of a:, e.g.{{template|p1}}.
Behavior switches
[????????]
| Switch | Description |
|---|---|
| __TOC__ | Places the page's table of contents (TOC) at the word's position. |
| __FORCETOC__ | Forces the TOC to appear in its default position. Can be used anywhere on a page. |
| __NOTOC__ | Suppresses the appearance of the page's TOC. Can be used anywhere on a page. |
| __NOEDITSECTION__ | Hides the "edit" links normally beside all headings on the page. To hide the edit link beside a particular heading, specify the heading using e.g. an HTML tag such as <h2>heading</h2> rather than with the usual wiki equals-signs syntax (e.g. == heading ==?).
|
| __NEWSECTIONLINK__ | On non-talk pages, adds a "??? ????????" link as a means to add a new section to the page. |
| __NONEWSECTIONLINK__ | Removes the "??? ????????" link (the add-new-section link) on talk pages. |
| __NOGALLERY__ | Replaces thumbnails on a category page with normal links. |
| __HIDDENCAT__ | Makes a category hidden when included on that category's page. |
| __INDEX__ | Instructs search engines to index the page. |
| __NOINDEX__ | Instructs search engines not to index the page. See Wikipedia:Controlling search engine indexing. |
| __STATICREDIRECT__ | Prevents the link on a redirection page from being updated automatically when the page to which it redirects is moved (and "Update any redirects that point to the original title" is selected). Also instructs interwiki bots to treat the page as if an article. |
| __DISAMBIG__ | Marks a page as a disambiguation page, adds it to Special:DisambiguationPages and places inward links in Special:DisambiguationPageLinks. (See mw:Extension:Disambiguator.) |
| {{DISPLAYTITLE:title}} | Used to amend the displayed form of the page's title. |
| {{DEFAULTSORT:sortkey}} | Sets the default key (the index) under which the page is categorised. |
| {{NOEXTERNALLANGLINKS}} | (equivalent to {{NOEXTERNALLANGLINKS|*}}?) Suppresses the automated inclusion of Wikidata interlanguage links on the lefthand side of the page. Links to particular rather than all languages may be suppressed by using {{NOEXTERNALLANGLINKS|list}}, where list a pipe-delimited list of language codes (e.g. {{NOEXTERNALLANGLINKS|fr|es|ja}} to suppress the French ("fr"), Spanish ("es") and Japanese ("ja") interlanguage links). |
Variables
[????????]| Page name variable | Output | Description |
|---|---|---|
| {{FULLPAGENAME}} | ?????:Magic words | Canonical page name. Title line. Title unless letter-case is altered with {{DISPLAYTITLE}}.
|
| {{PAGENAME}} | Magic words | Title line excluding namespace. |
| {{BASEPAGENAME}} | Magic words | Title of parent page, excluding namespace. |
| {{ROOTPAGENAME}} | Magic words | Title of topmost parent (before all subpages), excluding namespace. |
| {{SUBPAGENAME}} | Magic words | On a subpage, rightmost portion of current title; higher subpagenames show as backlinks. |
| {{ARTICLEPAGENAME}} | ?????:Magic words | Title of the subject page associated with the current page. These are useful on talk pages (but see note about Category talk pages). |
| {{SUBJECTPAGENAME}} | ?????:Magic words | |
| {{TALKPAGENAME}} | ????? ??????:Magic words | Title of the talk page associated with the current page. Useful on subject pages. |
| {{NAMESPACENUMBER}} | 12 | Number of the current page's namespace. |
| {{NAMESPACE}} | ????? | Namespace of the title. |
| {{ARTICLESPACE}} | ????? | On a talk page, the namespace part of the title of the associated subject page. |
| {{SUBJECTSPACE}} | ????? | |
| {{TALKSPACE}} | ????? ?????? | Namespace of the talk page associated with the current page. |
{{FULLPAGENAMEE}},
{{PAGENAMEE}}, (etc.) |
%E0%AC%B8%E0%AC%B9%E0%AC%AF%E0%AD%8B%E0%AC%97:Magic_words,
Magic_words, (etc.) |
Adding an E to the end of the above variables, renders the above encoded for use in MediaWiki URLs (i.e. with underscores replacing spaces). |
| {{SHORTDESC}} | Only works on the English Wikipedia, where it displays a short description below the article title on mobile platforms. See Wikipedia:Short description#Implementation. |
Note: The magic words above can also take a parameter, in order to parse values on a page other than the current page. A colon (?:?) is used to pass the parameter, rather than a pipe (?|?) that is used in templates, like {{MAGICWORD:value}}. For example, {{TALKPAGENAME:Wikipedia:MOS}} returns Wikipedia talk:MOS on any page. See meta:Help:Page name for more details of parser functions.
Note: In the "Category" and "Category talk" namespaces, to wikilink (some) page name variables may require prefixing a colon to avoid unwanted categorization.
| Site variable | Example | Description |
|---|---|---|
| {{SITENAME}} | ?????????? | |
| {{SERVER}} | //or.wikipedia.org | |
| {{SERVERNAME}} | or.wikipedia.org | |
| {{SCRIPTPATH}} | /w | |
| {{CURRENTVERSION}} | 1.45.0-wmf.12 (4f0e620) | Returns current MediaWiki version. |

Parser functions
[????????]Metadata
[????????]| Function | Description |
|---|---|
| {{PAGEID}} | Unique page identifier number. |
| {{PAGESIZE:fullpagename}} | Size of named page in bytes. |
| {{PROTECTIONLEVEL:action|fullpagename}} | Protection level assigned to action ("edit", "move", etc.) on named page. |
| {{PROTECTIONEXPIRY:action|fullpagename}} | Protection expiry assigned to action ("edit", "move", etc.) on named page. |
| {{PENDINGCHANGELEVEL}} | Protection level for pending changes on the current page. |
| {{PAGESINCATEGORY:categoryname}} | Number of pages in the category named categoryname. |
| {{NUMBERINGROUP:groupname}} | Number of users in the user group named groupname. |
To output numbers without comma separators (for example, as "123456789" rather than "123,456,789"), append the parameter |R.
Formatting
[????????]| Function | Description |
|---|---|
| {{lc:string}} | Converts all characters in string to lower case. |
| {{lcfirst:string}} | Converts first character of string to lower case. |
| {{uc:string}} | Converts all characters in string to upper case. |
| {{ucfirst:string}} | Converts first character of string to upper case. |
| {{formatnum:unformatted_number}} {{formatnum:formatted_num |R}} |
Adds comma separators to an unformatted_number (e.g. 123456789 becomes ??,??,??,???). To remove such formatting, use {{formatnum:formatted_number|R}} (i.e. {{formatnum:7,654,321|R}}, for example, produces 7654321). |
| {{#dateformat:date|format}} {{#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}} {{padleft:xyz|length|padstr}} {{padright:xyz|length|padstr}} |
Pad with zeroes '0' to the right or left, to fill the given length; an alternative padding string can be given as a third parameter; the repeated padding string (padstr) will be truncated if its length does not evenly divide the required number of characters. |
| {{plural:N|singular|plural}} | Outputs singular if N is equal to 1, otherwise outputs plural. See the documentation at mediawiki.org for more details. |
| {{#time:format|object}} {{#timel:format|object}} {{#time:d F Y|date|langcode}} |
Used to format dates and times, for ISO format, dots or English month names. #timel is based on local time as defined for each wiki; for English Wikipedia, this is identical to #time. The optional 3rd parameter is the output language code (French, German, Swedish: fr, de, sv, etc.). Example Finnish: {{#time:d F Y|June 30, 2016|fi}} shows: 30 kes?kuu 2016 (June). ISO to German: {{#time:d. M Y|2025-08-07|de}} shows: 31. Okt. 1987. For format codes, see: mw:Help:Extension:ParserFunctions##time. Use the format {{#time: H:i, j F Y (e)|...}} to match the format used by timestamps in signatures. |
| {{gender:user|m_out|f_out|u_out}} | Outputs m_out, f_out or u_out according to whether the gender specified in user?'s preferences is, respectively, male, female or unspecified. Other parameter permutations are available, see mw:Help:Magic words#gender and translatewiki:Gender. |

| {{canonicalurl:fullpagename |query}} | Absolute path, including protocol prefix, to page name. The query parameter is optional. |
| {{filepath:filename}} | Absolute path to the media file filename. |
| {{urlencode:string}} | Encodes string for use in URL query strings; {{urlencode:test string}}, for example, produces: test+string. To encode string for use in URL paths or MediaWiki page names, append, respectively, |PATH or |WIKI (to produce "test%20string" or "test_string").
|
| {{anchorencode:string}} | Input encoded for use in MediaWiki URL section anchors. |
| {{ns:n}} | Returns the name of the namespace whose index is the number n. For MediaWiki URLs, use {{nse:}}. |
| {{#rel2abs:path}} | Converts a relative file path to an absolute path. |
| {{#titleparts:fullpagename|number|first segment}} | Splits the fullpagename (title) into that number of segments. |
Conditional
[????????]| Function | Description |
|---|---|
| {{#expr:expression}} | Evaluates expression (see m:Help:Calculation). |
| {{#if:string |result1 |result2}} | Outputs result2 if string is empty, otherwise outputs result1. |
| {{#ifeq:string1|string2 |result1 |result2}} | Outputs result1 if string1 and string2 are equal (alphabetically or numerically), otherwise outputs result2. |
| {{#iferror:test_string |result1 |result2}} | Outputs result1 if test_string generates a parsing error, otherwise outputs result2. |
| {{#ifexpr:expression |result1 |result2}} | Outputs result1 if expression? is true, otherwise outputs result2. |
| {{#ifexist:pagetitle |result1 |result2}} | Outputs result1 if the page [[pagetitle]] exists, otherwise outputs result2. Note that underscores are needed for spaces in namespaces. |
| {{#switch:string |c1=r1 |c2=r2 ... |default}} | Outputs r1 if string is c1, r2 if string is c2, etc., otherwise outputs default (if provided). |
If, in these conditional functions, empty unnamed parameters are to be parsed as empty rather than as text (i.e. as empty rather than as the text "{{{1}}}", "{{{2}}}", etc.), they will require trailing pipes (i.e. {{{1|}}}, {{{2|}}}, etc., rather than {{{1}}}, {{{2}}}, etc.).
- For the use of these functions in tables, see Wikipedia:Conditional tables.
