{{#expr: ifade }}

Kullanılabilir işleçler (operatörler) yandaki tabloda öncelik sırasına göre listelenmiştir, her bir işlecin özelliğiyle ilgili daha ayrıntılı bilgi edinmek için Help:Calculation sayfasına bakın. Sonuçların doğruluğu ve düzeni viki üzerinde çalıştırılan işletim sistemine ve site dilinin sayı düzenine bağlı olarak değişkenlik gösterir.

Mantıksal cebir (boole cebiri) kullanılarak yapılan işlemlerde, sıfır false olarak ve sıfır dışındaki, negatif veya pozitif her değer true olarak değerlendirilir:

{{#expr: 1 and -1 }} → 1

{{#expr: 1 and 0 }} → 0

Boş girilen bir ifadenin dönüşü boş bir metindir. Geçersiz ifadeler hata olarak döner, bu hatalar #iferror ile yakalanabilir:

{{#expr: }} →

{{#expr: 1+ }} → Expression error: Missing operand for +.

{{#expr: 1 foo 2 }} → Expression error: Unrecognized word "foo".

The order of addition and subtraction operands before or after a number is meaningful, and may be treated as a positive or negative value instead of as an operand with an erroneous input:

{{#expr: +1 }} → 1

{{#expr: -1 }} → -1

{{#expr: + 1 }} → 1

{{#expr: - 1 }} → -1

Note, if using the output of magic words, you must raw format them in order to remove commas, and translate the numerals. For example {{NUMBEROFUSERS}} results in {{NUMBEROFUSERS}}, where we want {{NUMBEROFUSERS}} which can be obtained by {{NUMBEROFUSERS}}. This is especially important in some languages, where numerals are translated. For example, in Bengali, {{NUMBEROFUSERS}} produces ৩০,০৬১.

{{#expr:{{NUMBEROFUSERS}}+100}} → 101.678

{{#expr:{{formatnum:{{NUMBEROFUSERS}}|R}}+100}} → 1678283

Uyarı:

mod operatörü ikincil değişkenin bazı durumları için hatalı sonuç verir:

{{#expr: 123 mod (2^64-1)}} → Division by zero. ("123" sonucunu değil, boş bir metin verir)

If you want to do calculations based on dates (If current date and time is after some other date and time), first convert the time to number of seconds after January 1, 1970 using {{#time: U }}, then you can simply add and subtract dates.

Yuvarlama

Rounds off the number on the left to a multiple of 1/10 raised to a power, with the exponent equal to the truncated value of the number given on the right.

To round up or down use unary ceil or floor respectively.

Kod Sonuç Yuvarlama yöntemi

{{#expr: 1/3 round 5 }} 0.33333 Sondaki rakam <5, yuvarlanmadı

{{#expr: 1/6 round 5 }} 0.16667 Sondaki rakam >=5, üst rakama yuvarlandı

{{#expr: 8.99999/9 round 5 }} 1 Tekrar, sondaki rakam yuvarlandı ve bu da sonraki rakamı tekrar yuvarladı

{{#expr: 1234.5678 round -2 }} 1200 En yakın yüzlüğe yuvarlandı çünkü negatif değerler virgülün solundaki basamakları yuvarlar

{{#expr: 1234.5678 round 2 }} 1234.57 En yakın 1/100 basamağına yuvarladı çünkü pozitif değerler virgülün sağındaki basamakları yuvarlar

{{#expr: 1234.5678 round 2.3 }} 1234.57 Yuvarlanacak basamak sayısını belirleyecek değerdeki ondalık kısım sonucu değiştirmez

{{#expr: trunc 1234.5678 }} 1234 Ondalık kısım sıfırlandı

En yakın tam sayıya yuvarlama

{{#expr: 1/3 round 0 }} 0 En yakın tam sayıya indirme, yani sıfır

{{#expr: 1/2 round 0 }} 1 En yakın tam sayıya çıkarma, yani bir

{{#expr: 3/4 round 0 }} 1 En yakın tam sayıya çıkarma, yani bir

{{#expr: -1/3 round 0 }}

-0

En yakın tam sayıya çıkarma, yani sıfır

Uyarı:

Sıfırdaki negatif (-) işareti eşitlik problemlerine sebep olabilir

{{#expr: -1/2 round 0 }} -1 En yakın tam sayıya indirme, yani eksi bir

{{#expr: -3/4 round 0 }} -1 En yakın tam sayıya indirme, yani eksi bir

"ceil" (üst), "floor" (alt) sayıya yuvarlama

{{#expr: floor(1/3) }} 0 En yakın "küçük" tam sayıya yuvarla, yani sıfır

{{#expr: ceil(-1/3) }}

-0

En yakın büyük tam sayıya yuvarla, yani sıfır

Uyarı:

Sıfırdaki negatif (-) işareti eşitlik problemlerine sebep olabilir

{{#expr: floor(-1/3) }} -1 En yakın küçük tam sayıya yuvarla, yani eksi bir

{{#expr: ceil 1/3 }}

0.33333333333333

Yuvarlanmadı, 1 zaten tam sayı

Uyarı:

(ceil 1)/3 şeklinde yorumlanır, ceil(1/3) şeklinde değil

#if

Bu işlev ilk parametrenin boş olup olmadığını sınar. Eğer sınanacak dizge yalnızca boşluk karakterleri (boşluk, satır atlama vb.) içeriyorsa sonuç yanlış (false) olur.

{{#if: sınanacak dizge (koşul) | doğruysa değeri | yanlışsa değeri }}

{{#if: ilk parametre | ikinci parametre | üçüncü parametre }}

Bu fonksiyon ilk parametrenin doluluğunu sınar. Eğer ilk parametre boş değilse fonksiyon ikinci değişkeni gösterir. Eğer ilk parametre boş ise ya da sadece boşluk karakterleri (boşluk, satır atlama vs.) varsa üçüncü değişkeni gösterir.

{{#if: | yes | no}} → no

{{#if: string | yes | no}} → yes

{{#if: | yes | no}} → no

Sınama dizgisi her zaman düz metin olarak yorumlanır, bu yüzden matematiksel ifadeler değerlendirilmez:

{{#if: 1==2 | yes | no }} → yes

{{#if: 0 | yes | no }} → yes

Dönüş değerlerinin biri veya ikisi birden girilmeyebilir:

{{#if: foo | yes }} → yes

{{#if: | yes }} →

{{#if: foo | | no}} →

Fonksiyon iç içe (yuvalanmış/nested) olabilir. Bunun için; içteki #if fonksiyonunu yuvalanır #if fonksiyonunun üçüncü parametresi #if fonksiyonuyla kapatılır. En az yedi yuva derinliği yapmak mümkündür. Fakat bu wiki'ye ya da hafıza limitine göre belirlenebilir.

Örneğin:{{#if: sınama metni| metin boş değilse değer|{{#if:sınama metni|metin boş değilse değer|metin boşsa ya da boşluk karakterleri varsa değer}} }}

Bu ayrıştırıcı işlevin daha fazla kullanım örneği için Help:Parser functions in templates/tr sayfasına bakın.

#ifeq

Bu ayrıştırıcı fonksiyon iki metini karşılaştırır ve aynı olup olmadıklarını sınar.

{{#ifeq: string 1 | string 2 | value if identical | value if different }}

Eğer metinler sayısal değer içeriyorsa, sayısal değer karşılaştırılır:

{{#ifeq: 01 | 1 | equal | not equal}} → equal

{{#ifeq: 0 | -0 | equal | not equal}} → equal

{{#ifeq: 1e3 | 1000 | equal | not equal}} → equal

{{#ifeq: {{#expr:10^3}} | 1000 | equal | not equal}} → equal

Aksi takdirde metinler karşılaştırılırsa, karşılaştırma büyük/küçük harfe duyarlı olur:

{{#ifeq: foo | bar | equal | not equal}} → not equal

{{#ifeq: foo | Foo | equal | not equal}} → not equal

{{#ifeq: "01" | "1" | equal | not equal}} → not equal (yukarıdaki örneği tırnak (") olmadan karşılaştırın)

{{#ifeq: 10^3 | 1000 | equal | not equal}} → not equal (yukarıdaki örneği #expr ile karşılaştırın)

Pratik bir örnek olması için var olan bir şablon Şablon:Size standart kısa ve uzun boyutları ayarlamak için kullanıldı, kodu:

{{#ifeq: {{{1|}}} | short | 20 | 40}}

şu şekilde sonuçlanır:

{{size|short}} → 20

{{size|20}} → 40

{{size}} → 40

Uyarı:

#ifeq ve #switch ile sayısal karşılaştırma yapmak #expr ile yapılan karşılaştırmaya eş değildir:

{{#ifeq: 12345678901234567 | 12345678901234568 | equal | not equal}} → not equal

{{#switch: 12345678901234567 | 12345678901234568 = equal | not equal}} → not equal

çünkü PHP iki tür tam sayıyı karşılaştırır:

{{#ifexpr: 12345678901234567 = 12345678901234568 | equal | not equal}} → equal

because MediaWiki converts literal numbers in expressions to type float, which, for large integers like these, involves rounding.

Uyarı:

Tags and parser functions inside parser tags (such as <nowiki>) are temporarily replaced by a unique code. This affects comparisons:

{{#ifeq: <nowiki>foo</nowiki> | <nowiki>foo</nowiki> | equal | not equal}} → not equal

{{#ifeq: <math>foo</math> | <math>foo</math> | equal | not equal}} → not equal

{{#ifeq: {{#tag:math|foo}} | {{#tag:math|foo}} | equal | not equal}} → not equal

{{#ifeq: [[foo]] | [[foo]] | equal | not equal}} → equal

If the strings to be compared are given as equal calls to the same template containing such tags, then the condition is true, but in the case of two templates with identical content containing such tags it is false.

Uyarı:

Be careful when comparing against the current page title using the page name magic words. These magic words convert special characters into numeric HTML entities. This may result in misleading results. For example, if you are on a page titled "L'Aquila"...

{{#ifeq: L'Aquila | {{FULLPAGENAME}} | equal | not equal}} → not equal

To work around this, apply the magic word to both parameters:

{{#ifeq: {{FULLPAGENAME: L'Aquila}} | {{FULLPAGENAME}} | equal | not equal}} → equal

#iferror

This function takes an input string and returns one of two results; the function evaluates to true if the input string contains an HTML object with class="error", as generated by other parser functions such as #expr, #time and #rel2abs, template errors such as loops and recursions, and other "failsoft" parser errors.

{{#iferror: test string | value if error | value if correct }}

One or both of the return strings can be omitted. If the correct string is omitted, the test string is returned if it is not erroneous. If the error string is also omitted, an empty string is returned on an error:

{{#iferror: {{#expr: 1 + 2 }} | error | correct }} → correct

{{#iferror: {{#expr: 1 + X }} | error | correct }} → error

{{#iferror: {{#expr: 1 + 2 }} | error }} → 3

{{#iferror: {{#expr: 1 + X }} | error }} → error

{{#iferror: {{#expr: 1 + 2 }} }} → 3

{{#iferror: {{#expr: 1 + X }} }} → ‌

{{#iferror: <strong class="error">a</strong> | error | correct }} → error

#ifexpr

This function evaluates a mathematical expression and returns one of two strings depending on the boolean value of the result:

{{#ifexpr: expression | value if true | value if false }}

The expression input is evaluated exactly as for #expr above, with the same operators being available. The output is then evaluated as a boolean expression.

An empty input expression evaluates to false:

{{#ifexpr: | yes | no}} → no

As mentioned above, zero evaluates to false and any nonzero value evaluates to true, so this function is equivalent to one using #ifeq and #expr only:

{{#ifeq: {{#expr: expression }} | 0 | value if false | value if true }}

except for an empty or wrong input expression (an error message is treated as an empty string; it is not equal to zero, so we get value if true).

{{#ifexpr: = | yes | no }} → Expression error: Unexpected = operator.

comparing

{{#ifeq: {{#expr: = }} | 0 | no | yes }} → yes

Either or both the return values may be omitted; no output is given when the appropriate branch is left empty:

{{#ifexpr: 1 > 0 | yes }} → yes

{{#ifexpr: 1 < 0 | yes }} →

{{#ifexpr: 0 = 0 | yes }} → yes

{{#ifexpr: 1 > 0 | | no}} →

{{#ifexpr: 1 < 0 | | no}} → no

{{#ifexpr: 1 > 0 }} →

#ifexist

This function takes an input string, interprets it as a page title, and returns one of two values depending on whether or not the page exists on the local wiki.

{{#ifexist: page title | value if exists | value if doesn't exist }}

The function evaluates to true if the page exists, whether it contains content, is visibly blank (contains meta-data such as category links or magic words, but no visible content), is blank, or is a redirect. Only pages that are redlinked evaluate to false, including if the page used to exist but has been deleted.

{{#ifexist: Help:Extension:ParserFunctions/tr | exists | doesn't exist }} → exists

{{#ifexist: XXHelp:Extension:ParserFunctions/trXX | exists | doesn't exist }} → doesn't exist

The function evaluates to true for system messages that have been customized, and for special pages that are defined by the software.

{{#ifexist: Special:Watchlist | exists | doesn't exist }} → exists

{{#ifexist: Special:CheckUser | exists | doesn't exist }} → exists (because the CheckUser extension is installed on this wiki)

{{#ifexist: MediaWiki:Copyright | exists | doesn't exist }} → exists (because MediaWiki:Copyright has been customized)

If a page checks a target using #ifexist:, then that page will appear in the Special:WhatLinksHere list for the target page. So if the code {{#ifexist:Foo}} were included live on this page (Help:Extension:ParserFunctions/tr), Special:WhatLinksHere/Foo will list Help:Extension:ParserFunctions/tr.

On wikis using a shared media repository, #ifexist: can be used to check if a file has been uploaded to the repository, but not to the wiki itself:

{{#ifexist: File:Example.png | exists | doesn't exist }} → doesn't exist

{{#ifexist: Image:Example.png | exists | doesn't exist }} → doesn't exist

{{#ifexist: Media:Example.png | exists | doesn't exist }} → exists

If a local description page has been created for the file, the result is exists for all of the above.

#ifexist: does not work with interwiki links.

ifexist limits

#ifexist: is considered an "expensive parser function"; only a limited number of which can be included on any one page (including functions inside transcluded templates). When this limit is exceeded, any further #ifexist: functions automatically return false, whether the target page exists or not, and the page is categorized into Category:Pages with too many expensive parser function calls. The name of the tracking category may vary depending on the content language of your wiki.

For some use cases it is possible to emulate the ifexist effect with css, by using the selectors a.new (to select links to unexisting pages) or a:not(.new) (to select links to existing pages). Furthermore, since the number of expensive parser functions that can be used on a single page is controlled by $wgExpensiveParserFunctionLimit, one can also increase the limit in LocalSettings.php if needed.

#rel2abs

This function converts a relative file path into an absolute filepath.

{{#rel2abs: path }}

{{#rel2abs: path | base path }}

Within the path input, the following syntax is valid:

. → the current level
.. → "go up one level"
/foo → "go down one level into the subdirectory /foo"

If the base path is not specified, the full page name of the page will be used instead:

{{#rel2abs: /quok | Help:Foo/bar/baz }} → Help:Foo/bar/baz/quok

{{#rel2abs: ./quok | Help:Foo/bar/baz }} → Help:Foo/bar/baz/quok

{{#rel2abs: ../quok | Help:Foo/bar/baz }} → Help:Foo/bar/quok

{{#rel2abs: ../. | Help:Foo/bar/baz }} → Help:Foo/bar

Invalid syntax, such as /. or /./, is ignored. Since no more than two consecutive full stops are permitted, sequences such as these can be used to separate successive statements:

{{#rel2abs: ../quok/. | Help:Foo/bar/baz }} → Help:Foo/bar/quok

{{#rel2abs: ../../quok | Help:Foo/bar/baz }} → Help:Foo/quok

{{#rel2abs: ../../../quok | Help:Foo/bar/baz }} → quok

{{#rel2abs: ../../../../quok | Help:Foo/bar/baz }} → Error: Invalid depth in path: "Help:Foo/bar/baz/../../../../quok" (tried to access a node above the root node).

#switch

This function compares one input value against several test cases, returning an associated string if a match is found.

{{#switch: comparison string
 | case = result
 | case = result
 | ...
 | case = result
 | default result
}}

Examples:

{{#switch: baz | foo = Foo | baz = Baz | Bar }} → Baz

{{#switch: foo | foo = Foo | baz = Baz | Bar }} → Foo

{{#switch: zzz | foo = Foo | baz = Baz | Bar }} → Bar

#switch allows an editor to add information in one template and this information will be visible in several other templates which all have different formatting.

Default

The default result is returned if no case string matches the comparison string:

{{#switch: test | foo = Foo | baz = Baz | Bar }} → Bar

In this syntax, the default result must be the last parameter and must not contain a raw equals sign.

{{#switch: test | Bar | foo = Foo | baz = Baz }} →

{{#switch: test | foo = Foo | baz = Baz | B=ar }} →

Alternatively, the default result may be explicitly declared with a case string of "#default".

{{#switch: comparison string
 | case = result
 | case = result
 | ...
 | case = result
 | #default = default result
}}

Default results declared in this way may be placed anywhere within the function:

{{#switch: test | foo = Foo | #default = Bar | baz = Baz }} → Bar

If the default parameter is omitted and no match is made, no result is returned:

{{#switch: test | foo = Foo | baz = Baz }} →

Grouping results

It is possible to have 'fall through' values, where several case strings return the same result string. This minimizes duplication.

{{#switch: comparison string
 | case1 = result1
 | case2 
 | case3 
 | case4 = result2
 | case5 = result3
 | case6 
 | case7 = result4
 | #default = default result
}}

Here cases 2, 3 and 4 all return result2; cases 6 and 7 both return result4

Comparison behavior

As with #ifeq, the comparison is made numerically if both the comparison string and the case string being tested are numeric; or as a case-sensitive string otherwise:

{{#switch: 0 + 1 | 1 = one | 2 = two | three}} → three

{{#switch: {{#expr: 0 + 1}} | 1 = one | 2 = two | three}} → one

{{#switch: a | a = A | b = B | C}} → A

{{#switch: A | a = A | b = B | C}} → C

A case string may be empty:

{{#switch: | = Nothing | foo = Foo | Something }} → Nothing

Once a match is found, subsequent cases are ignored:

{{#switch: b | f = Foo | b = Bar | b = Baz | }} → Bar

Uyarı:

Numerical comparisons with #switch and #ifeq are not equivalent with comparisons in expressions (see also above):

{{#switch: 12345678901234567 | 12345678901234568 = A | B}} → B

{{#ifexpr: 12345678901234567 = 12345678901234568 | A | B}} → A

Raw equal signs

"Case" strings cannot contain raw equals signs. To work around this, create a template {{=}} containing a single equals sign: =.

Example:

{{#switch: 1=2

| 1=2 = raw

| 1<nowiki>=</nowiki>2 = nowiki

| 1=2 = html

| 1{{=}}2 = template

| default

}} → html

Note: For a simple real life example of the use of this function, check Template:NBA color. Two complex examples can be found at Template:Extension and Template:BOTREQ.

Replacing #ifeq

#switch can be used to reduce expansion depth.

For example:

{{#switch:{{{1}}} |condition1=branch1 |condition2=branch2 |condition3=branch3 |branch4}}

is equivalent to

{{#ifeq:{{{1}}}|condition1 |branch1 |{{#ifeq:{{{1}}}|condition2 |branch2 |{{#ifeq:{{{1}}}|condition3 |branch3 |branch4}}}}}}

(i.e.

{{#ifeq:{{{1}}}|condition1 |<!--then-->branch1 |<!--else-->{{#ifeq:{{{1}}}|condition2 |<!--then-->branch2 |<!--else-->{{#ifeq:{{{1}}}|condition3 |<!--then-->branch3 |<!--else-->branch4}}}}}}

)

This parser function takes a date and/or time (in the Gregorian calendar) and formats it according to the syntax given. A date/time object can be specified; the default is the value of the magic word {{CURRENTTIMESTAMP}} – that is, the time the page was last rendered into HTML.

{{#time: format string }}

{{#time: format string | date/time object }}

{{#time: format string | date/time object | language code }}

The list of accepted formatting codes is given in the table to the right. Any character in the formatting string that is not recognized is passed through unaltered; this applies also to blank spaces (the system does not need them for interpreting the codes). There are also two ways to escape characters within the formatting string:

A backslash followed by a formatting character is interpreted as a single literal character
Characters enclosed in double quotes are considered literal characters, and the quotes are removed.

In addition, the digraph xx is interpreted as a single literal "x".

{{#time: Y-m-d }} → 2014-08-01

{{#time: [[Y]] m d }} → 2014 08 01

{{#time: [[Y (year)]] }} → 2014 (14UTCamFri, 01 Aug 2014 00:13:09 +0000)

{{#time: [[Y "(year)"]] }} → 2014 (year)

{{#time: i's" }} → 13'09"

The date/time object can be in any format accepted by PHP's strtotime() function. Both absolute (eg 20 December 2000) and relative (eg +20 hours) times are accepted.

{{#time: r|now}} → Fri, 01 Aug 2014 00:13:09 +0000
{{#time: r|+2 hours}} → Fri, 01 Aug 2014 02:13:09 +0000
{{#time: r|now + 2 hours}} → Fri, 01 Aug 2014 02:13:09 +0000

The language code in ISO 639-3 (?) allows the string to be displayed in the chosen language {{#time:d F Y|1988-02-28|nl}} → 28 februari 1988
{{#time:l|now|uk}} → п'ятниця
{{#time:d xg Y|20 June 2010|pl}} → 20 czerwca 2010

If you've calculated a Unix timestamp, you may use it in date calculations by pre-pending an @ symbol.

{{#time: U | now }} → 1406851989
{{#time: r|@1406851989}} → Fri, 01 Aug 2014 00:13:09 +0000

Uyarı:

The range of acceptable input is 1 January 0111 → 31 December 9999. For the years 100 through 110 the output is inconsistent, Y and leap years are like the years 100-110, r, D, l and U are like interpreting these years as 2000-2010.

{{#time: d F Y | 29 Feb 0100 }} → 01 Mart 0100
(correct, no leap year), but
{{#time: r | 29 Feb 0100 }} → Tue, 01 Mar 0100 00:00:00 +0000 (wrong, even if 100 is interpreted as 2000, because that is a leap year)
{{#time: d F Y | 15 April 10000 }} → Error: Invalid time.
{{#time: r | 10000-4-15 }} → Sat, 15 Apr 2000 10:00:00 +0000

Year numbers 0-99 are interpreted as 2000-2069 and 1970-1999, even when written with leading zeros:
{{#time: d F Y | 1 Jan 0069 }} → 01 Ocak 0069

{{#time: d F Y | 1 Jan 0070 }} → 01 Ocak 0070

The weekday is supplied for the years 100-110 and from 1753, for the years 111-1752 the r-output shows "Unknown" and the l-output "<>". As a consequence, the r-output is not accepted as input for these years.

Full or partial absolute dates can be specified; the function will "fill in" parts of the date that are not specified using the current values:

{{#time: Y | January 1 }} → 2014

Uyarı:

The fill-in feature is not consistent; some parts are filled in using the current values, others are not:

{{#time: Y m d H:i:s | June }} → 2014 06 01 00:00:00 Gives the start of the day, but the current day of the month and the current year. {{#time: Y m d H:i:s | 2003 }} → 2003 08 01 00:00:00 Gives the start of the day, but the current day of the year.

With MediaWiki r86805 - Code Review, a four-digit number is always interpreted as a year, never as hours and minutes:
{{#time: Y m d H:i:s | 1959 }} → 1959 08 01 00:00:00

A six-digit number is interpreted as hours, minutes and seconds if possible, but otherwise as an error (not, for instance, a year and month):
{{#time: Y m d H:i:s | 195909 }} → 2014 08 01 19:59:09 Input is treated as a time rather than a year+month code.
{{#time: Y m d H:i:s | 196009 }} → Error: Invalid time. Although 19:60:09 is not a valid time, 196009 is not interpreted as September 1960.

The function performs a certain amount of date mathematics:

{{#time: d F Y | January 0 2008 }} → 31 Aralık 2007

{{#time: d F | January 32 }} → Error: Invalid time.

{{#time: d F | February 29 2008 }} → 29 Şubat

{{#time: d F | February 29 2007 }} → 01 Mart

{{#time:Y-F|now -1 months}} → 2014-Temmuz

The total length of the format strings of the calls of #time is limited to 6000 characters [1].

Time Zone issue

There is a bug in this #time parser function (more specifically in PHP DateTime) that does not allow the passing-in of non-integers as relative time zone offsets. This issue does not apply when using an on-the-hour time zone, such as EDT. For example:

{{#time:g:i A | -4 hours }} ==> 8:13 PM

However, Venezuela is on a -4.5 hours time offset from UTC, and thus using its time zone will not normally allow the correct calculation of a relative time zone offset. Here's what happens:

{{#time:g:i A | -4.5 hours }} ==> 9:13 AM

To workaround this issue, simply convert the time into minutes or seconds, like this:

{{#time:g:i A | -270 minutes }} ==> 7:43 PM
{{#time:g:i A | -16200 seconds }} ==> 7:43 PM

(Tim Starling, the developer of this function, provided the exact syntax for this solution.)

#timel

This function is identical to {{#time: ... }}, except that it uses the local time of the wiki (as set in $wgLocaltimezone) when no date is given.

{{#time: Y-m-d }} → 2014-08-01

{{#timel: Y-m-d }} → 2014-08-01

{{#time: Y F d h:i:s}} → 2014 Ağustos 01 12:13:09

{{#timel: Y F d h:i:s}} → 2014 Ağustos 01 12:13:09

#titleparts

This function separates a pagetitle into segments based on slashes, then returns some of those segments as output.

{{#titleparts: pagename | number of segments to return | first segment to return }}

If the number of segments parameter is not specified, it defaults to "0", which returns all the segments from first segment (included). If the first segment parameter is not specified or is "0", it defaults to "1":

{{#titleparts: Talk:Foo/bar/baz/quok }} → Talk:Foo/bar/baz/quok

{{#titleparts: Talk:Foo/bar/baz/quok | 1 }} → Talk:Foo

{{#titleparts: Talk:Foo/bar/baz/quok | 2 }} → Talk:Foo/bar

{{#titleparts: Talk:Foo/bar/baz/quok | 2 | 2 }} → bar/baz

{{#titleparts: Talk:Foo/bar/baz/quok | | 2 }} → bar/baz/quok

Negative values are accepted for both values. Negative values for number of segments effectively 'strips' segments from the end of the string. Negative values for first segment translates to "start with this segment counting from the right":

{{#titleparts: Talk:Foo/bar/baz/quok | -1 }} → Talk:Foo/bar/baz Strips one segment from the end of the string. See also {{BASEPAGENAME}}.

{{#titleparts: Talk:Foo/bar/baz/quok | -4 }} → Strips all 4 segments from the end of the string

{{#titleparts: Talk:Foo/bar/baz/quok | -5 }} → Strips 5 segments from the end of the string (more than exist)

{{#titleparts: Talk:Foo/bar/baz/quok | | -1 }} → quok Returns last segment. See also {{SUBPAGENAME}}.

{{#titleparts: Talk:Foo/bar/baz/quok | -1 | 2 }} → bar/baz Strips one segment from the end of the string, then returns the second segment and beyond

{{#titleparts: Talk:Foo/bar/baz/quok | -1 | -2 }} → baz Start copying at the second last element; strip one segment from the end of the string

The string is split a maximum of 25 times; further slashes are ignored and the 25th element will contain the rest of the string. The string is also limited to 255 characters, as it is treated as a page title:

{{#titleparts: a/b/c/d/e/f/g/h/i/j/k/l/m/n/o/p/q/r/s/t/u/v/w/x/y/z/aa/bb/cc/dd/ee | 1 | 25 }} → y/z/aa/bb/cc/dd/ee

If for whatever reason you needed to push this function to its limit, although very unlikely, it is possible to bypass the 25 split limit by nesting function calls:

{{#titleparts: {{#titleparts: a/b/c/d/e/f/g/h/i/j/k/l/m/n/o/p/q/r/s/t/u/v/w/x/y/z/aa/bb/cc/dd/ee| 1 | 25 }} | 1 | 2}} → z

Uyarı: You can use #titleparts as a small "string parser & converter", but consider that it returns the first substring capitalized.

{{#titleparts: one/two/three/four|1|1 }} → One

{{#titleparts: one/two/three/four|1|2 }} → two

If lower case is needed, use lc: function to control output.

{{lc: {{#titleparts: one/two/three/four|1|1 }} }} → one

You can prepend a 'dummy' slash at the beginning of the string to get the correct first substring capitalization (uppercase or lowercase). Use |2 instead of |1 for first segment to return.

{{#titleparts: /one/two/three/four|1|2 }} → one

{{#titleparts: /One/two/three/four|1|2 }} → One

Uyarı: Certain characters that are illegal in a page title will cause #titleparts to not parse the string.

{{#titleparts: {one/two} | 1 | 1 }} → {one/two}. Does not produce the expected: {one

Uyarı:

{{#titleparts: [[page]]/123 | 1 | 2 }} → page/123

Uyarı: This function does not degrade gracefully if your input exceeds 255 characters. If the inputted string is 256 characters long or more, this function will simply toss the string back at you.

Strings parsing

An extension is available for additional string parsing, see Extension:StringFunctions.

General points

Substitution

Parser functions can be substituted by prefixing the hash character with subst::

{{subst:#ifexist: Help:Extension:ParserFunctions/tr | [[Help:Extension:ParserFunctions/tr]] | Help:Extension:ParserFunctions/tr }} → the code [[Help:Extension:ParserFunctions/tr]] will be inserted in the wikitext since the page Help:Extension:ParserFunctions/tr exists.

Uyarı:

The results of substituted parser functions are undefined if the expressions contain unsubstituted volatile code such as variables or other parser functions. For consistent results, all the volatile code in the expression to be evaluated must be substituted. See Help:Substitution.

Redirects

Especially {{#time:…|now-…}} could be handy in redirects to pages including dates, but this does not work.

Escaping pipe characters in tables

Parser functions will mangle wikitable syntax and pipe characters (|), treating all the raw pipe characters as parameter dividers. To avoid this, most wikis create the template Template:! with its contents only a raw pipe character (|) or use the {{!}} magic word which is available since MW 1.24. This 'hides' the pipe from the MediaWiki parser, ensuring that it is not considered until after all the templates and variables on a page have been expanded. It will then be interpreted as a table row or column separator. Alternatively, raw HTML table syntax can be used, although this is less intuitive and more error-prone.

You can also escape the pipe character for display as a plain, uninterpreted character using an HTML entity: | .

Description	You type	You get
Escaping pipe character as table row/column separator (most wikis)	{{!}}	\|
Escaping pipe character as a plain character	\|	\|

Stripping whitespace

Whitespace, including newlines, tabs, and spaces, is stripped from the beginning and end of all the parameters of these parser functions. If this is not desirable, comparison of strings can be done after putting them in quotation marks.

{{#ifeq: foo            |            foo | equal | not equal }}

→ equal

{{#ifeq: "foo           " | "           foo" | equal | not equal }}

→ not equal

For preventing trimming then- and else-parts, see m:Template:If. Some people use also <nowiki> </nowiki> instead of spaces.
