Is there any way to get revision information using the magic words for another page such as getting  or   from  ? This would be useful for keeping track of articles in a project for a list of pages. Technical 13 (talk) 15:44, 22 May 2013 (UTC)

_NOEDITSECTION_ on every page?
Hey there, I am using Mediawiki and I have problems with partly editing of pages, so I want to disable the "edit section" Button for the whole wiki. Is this possible?
 * If there was such a thing, I would think it would be listed on Manual:Configuration settings (alphabetical), which it is not. However, depending on which version of MediaWiki you are running you could just set the class (use to be   but was recently renamed   on some wikis like en.wikipedia) for to   in your MediaWiki:Common.css --  Technical 13 (talk) 12:48, 15 June 2013 (UTC)

__DISAMBIG__
Could someone please add the necessary documentation for __DISAMBIG__ (Extension:Disambiguator) here and, if you could be so kind, also at en:Wikipedia:Magic words? Thank you. -- Michael Bednarek (talk) 13:48, 11 July 2013 (UTC)
 * I was under the impression that this page was reserved for core (or at least ships with core extension) magic words and I don't remember seeing Extension:Disambiguator being in that package. Is this going to be a new inclusion in the default package? Technical 13 (talk) 10:26, 17 July 2013 (UTC)
 * When I look up magic words on the EN Wikipedia, I often end up looking at Help:Magic words here on MediaWiki, because that page is linked there, e.g. at en:Help:Magic words. My impression, which may well be wrong, is that MediaWiki documents the MediaWiki software. If that is not so, feel free to remove the entry about  again; in that case, I wonder whether it would be better to remove the mentioned link to MediaWiki at "en:Help:Magic words" as well. -- Michael Bednarek (talk) 12:21, 17 July 2013 (UTC)

Displaying the article's author on the page
Is there any magic word for that? For example displays the username/IP of the last user, who edited the article. How to display the username/IP of the user, who created the article?--185.31.48.30 09:45, 17 April 2014 (UTC)

Adding translatable docu to such a page is horrifying
This diff together with translate tags etc. causes fatals, so I gave up. Sorry for this. The standard nonsense error message "Fatal exception of MediaWiki exception" or what this is called will probably not help digging into the issue. --&#91;&#91;kgh&#93;&#93; (talk) 22:32, 4 July 2014 (UTC)

anchorencode
Did somebody change anchorencode ?

It now seems to strip italic markup, rather than encode it:

->

It just means that on en-wp, we have to clean up a few hundred articles where en:template:SfnRef (which uses anchorencode to generate anchors in footnotes) has anchors that are generated from italicised words. --RexxS (talk) 16:30, 6 July 2014 (UTC)

Variables that affect behaviour
Why are  and   listed under Variables when they do not "return information about the current page, wiki, or date"? Surely, since they "control the layout or behavior of the page", they should be listed at Behavior switches. This has come up at w:en:Help talk:Magic words. --Redrose64 (talk; at English Wikipedia) 10:14, 17 July 2014 (UTC)


 * I surmise it's because "switches" have a special  that doesn't accommodate parameters, whereas DISPLAYTITLE: and DEFAULTSORT: require them. Of the "variables" listed on this Help page, those that take parameters use them only to specify the object about which the "variable" should return information. As DISPLAYTITLE: and DEFAULTSORT: use parameters to set environmental states rather than report them, they are certainly a special case. Maybe they (along with NOEXTERNALLANGLINKS:) should be described as "environment variables", "behavior variables", or "behavior functions", and be placed in their own section or subsection in the page.
 * &#8942;
 * My suggestion at this point would be to rename the current "Behavior switches" section to "Behavior settings", move the current content of that section into a subsection called "Behavior switches", and add a second subsection called "Behavior functions" where DISPLAYTITLE:, DEFAULTSORT:, and NOEXTERNALLANGLINKS: are explained. I would also suggest that the list of "general types of magic words" in the lede be rewritten accordingly, mentioning the differences in effect, as well as in format, of the various kinds of magic words.
 * &#8942;
 * As an aside, I note that the keywords called "variables" on this Help page would probably be more accurately described as "functions", as they are used to return values that report some aspect of the environment, rather than to store arbitrarily-assigned values. But I guess that's a whole 'nother ball o' wax. — Jaydiem (talk) 16:56, 17 July 2014 (UTC)

Pages in category + sub categories
Is there a deeper penetrating {{ Pagesincategory that will also count the pages in the subcategories? That would be wonderful. Kmath87 (talk) 22:02, 8 August 2014 (UTC)
 * Not built in to the parser, Kmath87, no. You will have to use a recursive template, some kind of E:Loops, Lua (scribunto if I spelled that right), or javascript via the api if you want to have a count of all pages in a category & subcats. Technical 13 (talk) 12:14, 9 September 2014 (UTC)

What is the opposite of ?
If I know the page ID number, how do I find the page?

I see that, if I have the page name, the will give me the number, I'd just like to do it the other way around.

Magic Word ' | '
When I created the template for this magic word, I was having an issue using it with tables when I passed them in parameters for templates. I was using the syntax for specifying why I created the template. One thing to note is that the '|' character must come immediately after the closing tag. Otherwise, the white space messes up the parsing of the character when being used in tables; at least for what I was using it for. A newline simply doesn't cut it. --Erutan409 (talk) 14:48, 5 October 2014 (UTC)

Creation date
How can i get the "creation date" of a page? ... There exist some MAGICWORD?... or there exist a parser for get the creation date of a page?
 * I don't think that's possible by current Magic words. Bennylin (talk) 10:01, 10 December 2014 (UTC)

 * My current workaround on includes\parser\CoreParserFunctions.php (MW 23.1) is by adding the third argument ($argC) and one line of code. So now I could call the thumbnail for page 2 of the PDF . I'm not sure this is the best solution though. Bennylin (talk) 09:58, 10 December 2014 (UTC)

language magic word
It would appear that  where   is an ISO 639-3, three letter language code, either doesn't work as it should or that the documentation, such as it is, that suggests that ISO 639-3 language codes should work, is incorrect:

As a check, switching to ISO 639-1 works:

So, the questions are:
 * 1) Should  return a language name for three character ISO 639-3 language codes?
 * 2) If no, shouldn't the documentation state that  only supports ISO 639-1?
 * 3) If yes, where is the error and how does it get fixed?

—Trappist the monk (talk) 19:09, 10 January 2015 (UTC)


 * 1.1 no: The docu shouldn't say only, e.g.,  gives  . Some ISO 639-3 three letter codes have older ISO 639-1 two letter codes. From the work on RFC 4646 (predecessor of RFC 5646) I recall that ar and zh were the worst cases. Check out section 2.2.2 in 5646 about "macrolanguage zh". Admittedly arb also doesn't work, maybe the logic is "support only the shortest code". –Be..anyone (talk) 07:28, 13 January 2015 (UTC)


 * I'm confused. We aren't talking about language sub-tags; the documentation for   makes no mention of sub-tags.  The documentation says that it "[returns the] full name of the language for the given language code"  where 'language code' is vaguely defined as ISO 639-3.  Because   is a legitimate ISO 639-3 code (see at registration authority: ara)   should return Arabic which the language name assigned by the registration authority, shouldn't it?


 * —Trappist the monk (talk) 14:01, 14 January 2015 (UTC)
 * ISO 639 macrolanguage != language, if there is a problem it would be arb, not ara. –Be..anyone (talk) 08:45, 15 January 2015 (UTC)

Missing magic word
I just figured out that  outputs the current month in a non-zero padded format (shown here: ). The only problem is I am unsure of how to add it to the table without breaking the  tags, as each one is numbered.

EXPENSIVE tag
What does it mean when a magic word is tagged as 'expensive' ([EXPENSIVE])? For example, the  magic word. In the description column, it says:
 * [Expensive] Number of pages (including subcategories and files) in the given category. (Category:Help used for demonstration)

I had one thought of what the term 'expensive' means, which was that it ate up a lot of server memory? Or just in general, related to servers? Also, what makes some magic words 'expensive' and others not? Codyn329 (talk) 00:37, 12 March 2015 (UTC)
 * Check out Special:TrackingCategories and Category:Pages with too many expensive parser function calls, it's a tilt - game over effect. Articles be Turing Machines. Admittedly implementing the Ackermann function with templates is fun. –Be..anyone (talk) 17:34, 13 March 2015 (UTC)

urlencode
Is it possible to use this, to construct a link to an external webpage? An example would be greatly appreciated. --&#91;&#91;User:Bmrberlin&#124; Bernd M.&#93;&#93; (talk) 11:26, 31 March 2015 (UTC)
 * There are three examples in the 2nd column of three, and there's a cheat sheet in the 3rd column: In essence urlencode always does the same thing, percent-encode Unicode, e.g., the input á u+00E1 is encoded as %C3%A1 for UTF-8 C3A1=C000+0300+0080+0021, with C=1100 for length two bytes, 3=0011 for some high bits, 8=10(00) for two bits indicating a tail byte, and 21=(00)10 0001 for six low bits. Putting hi+lo together that is (bits) 0011 10 0001 = (hex) E1 = u+00E1 as expected.
 * For the space character u+0020 you have to say what you want. Default or QUERY encodes spaces as + suited for, e.g., google queries. WIKI encodes spaces as _ as you would need it for a . And PATH percent-encodes spaces as %20, suited for everything else, also known as URL-encoding. –Be..anyone (talk) 22:27, 31 March 2015 (UTC)

Hello!

I'm trying to pass a code snippet to a template. The code snippet uses ... < /syntaxhighlight>. I would then link to urlencode that code snippet, but urlencode: ... < /syntaxhighlight> doesn't work - presumably because syntaxhighlight somehow pulls the text out of the processing flow?

 * I did not fully understand your plan.
 * What is a “code snippet” and where is the problem?
 * Yes, your assumption is right: syntaxhighlight pulls the content out of the source text around.
 * The parser will put the stuff between  tags aside and transclude it later into the HTML document.
 * It is not possible to wrap something into  tags first and process the content later. The other way around works.
 * I fail to guess your expectation, is there a link supposed to be clickable, or shall the URL be displayed as code?
 * Note that for security reasons no external server must contribute code, but internal pages only and may be transcluded.
 * As far I read your intention try something like that:
 * Displaying generated URL, simply use, why coloured syntaxhighlight?




 * A clickable link with coloured syntaxhighlight as linktext, got passed a pipe-escaped code snippet, but no line breaks:

 * Greetings --PerfektesChaos (talk) 03:46, 6 May 2017 (UTC)


 * I'll try to summarize all requirements we have:
 * - Source code (actually "Overpass QL" language) is passed to template as a parameter
 * - Source code is rendered with syntax highlighting, preserving any new line characters
 * - An additional icon with hyperlink is generated, hyperlink includes source code as URL parameter. All newline characters need to be preserved!
 * - If you click on the hyperlink, you'll see exactly the same source code as shown on the wiki page.
 * See this page with the template in action: https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_API_by_Example
 * Bjohas wanted to find out some way to get rid of the sometimes insane escaping, like  instead of  . This would have the advantage, that a user can just copy & paste some source code as a template parameter and doesn't have to bother with escaping.

 * Template programming functionality is as best as possible yet.
 * Your real problem is easy escaping of  since those curly brackets are colliding with Wiki syntax.
 * The solution is quite easy:


 * The enclosing nowiki-tags when providing the  parameter will be stripped off before their content is passed as   inside the programming.
 * However, they will prevent  getting evaluated too early. It is intended that this should happen in advance usually. When returning, their remainders won’t get expanded any longer.
 * Should work. Enjoy.
 * Entire code should be able to be wrapped this way without touching anything inside.
 * The basic idea when this thread has been opened was fine: enclosing the program code into something to prevent from evaluation.
 * However, syntaxhighlight is a very powerful thing that does a lot of analysis and produces sophisticated output with error messages and highlighting. That is parked outside the wikitext and merged later when the HTML document is composed.
 * 15 years old nowiki has the same disabling effect, but on low level, just hiding its content once from parsing, and bye.
 * Greetings --PerfektesChaos (talk) 17:01, 6 May 2017 (UTC)


 * Thanks a lot for the detailed feedback! We have tried the nowiki approach before. Unfortunately, it has one major shortcoming: the source code is no longer passed on to the URL parameter: https://wiki.openstreetmap.org/wiki/User:Mmd/TurboExample - so our initial requirement  If you click on the hyperlink, you'll see exactly the same source code as shown on the wiki page. is no longer fulfilled using this approach. Not sure if there's some way to get around this limitation? Mmd-osm (talk) 07:29, 7 May 2017 (UTC)


 * Sorry, my approach has the same pitfall like syntaxhighlight, since nowiki also gets some kind of escaping and is not available for a parser function. I never noticed that yet.
 * Then, the only way to relieve your burden a bit is as follows:
 * Create an auxilary template:bracketed (or any other name).
 * Implement that as follows:

Good luck --PerfektesChaos (talk) 15:02, 7 May 2017 (UTC)
 * Transclude
 * At least slightly more readable.
 * The last remainig syntax with no extra template would be:
 * Many thanks for the suggestions - that's helpful! The developer of https://github.com/tyrasd/overpass-turbo has included an 'escaping mechanism' that essentially does this https://github.com/bjohas/mediawikiencode. Many thanks. Bjohas (talk) 10:43, 8 May 2017 (UTC)

On the letter-case of Variables
Hi, I'm recently working on a parser on wikitext, and have read this page so that I can decide whether a "transclusion" is actually a variable or parser function.

Variables, per definition, are uppercase words surrounded by double braces, so  are variables. On the contrary, I believe, parser functions (esp. those starting with ) are case-insensitive.

However, some "variables" are suprisingly case-insensitive, for example,  will still be parsed to  ; while others, e.g.   are not (e.g.  ). Though I can hard-code a list for these built-in variable and parser function names, I just couldn't figure out why some "variable"s should be case-insensitive, as it's against the definition in Help:Magic words.

Another problem that confuses me: in Help:Magic words, it's said that behavior switches, variables, and parser functions are three kinds of magic words, but in Manual:Magic words, magic words are defined as "… a technique for mapping a variety of wiki text strings to a single ID that is associated with a function. Both variables and parser functions use this technique." I was thinking about a name to indicate either variables or parser functions, while to distinguish from behavior switches, because variables and parser functions share the similar traits (e.g. the first argument is started with colon, not pipe). Now I'm using something like "Magic Template" but not sure whether it's suitable. Any suggestions? Thank you!

: bug
On pl wiki and (probably) some others doesn't count new pages, but counts deleted pages. Sławek Borewicz (talk) 19:45, 20 February 2018 (UTC)
 * I can confirm half of what you are reporting. There's been a lot of [//pl.wikipedia.org/wiki/Specjalna:Ostatnie_zmiany?hidepageedits=1&hidecategorization=1&hideWikibase=1&limit=50&days=7&urlversion=2 page creation and deletion] lately on plwiki, so I was able to monitor the statistics (more or less) "live" as pages were created and deleted. What I saw is this:
 * the page count decreased when pages were deleted (and, as far as I could tell, it seemed to be decreasing by the correct amount each time),
 * the article count decreased only sometimes when pages were deleted (which would be expected if some deleted pages counted as articles and some didn't),
 * the article count increased but the page count did not change when an article (with links) was created, and
 * the page count did not increase when a new page was created outside of the main namespace.
 * The last two things do seem to be a bug and not just due to lag. I watched for more than 25 minutes and never saw the page count go up despite multiple page creations in that time. I guess this deserves a Phabricator task (i.e., bug report). - dcljr (talk) 21:17, 20 February 2018 (UTC)
 * Turns out, this was a known bug that has been fixed.

JS to make "wgRevisionId" a magic word
Hi,

I'm using Extension:Approved Revisions [1] and I have a need to be able to display the revision ID of the page revision currently being viewed. From the MW Manual page on Javascript [2] I see that the variable "wgRevisionId" contains this information and is exposed to mediawiki for use, but it is not clear to me how to do so. I would like to create a magic word [3] called  that outputs the revision ID of the revision being viewed such that it can be used in other parser logic

For example:

Can someone please help me identify the way to make a magic word that contains the value of "wgRevisionId"?

CURRENTWEEK/YEAR when 31 Dec is on a Monday
Hello from Monday, 31 Dec 2018, where CURRENTWEEK returns 1 and CURRENTYEAR returns 2018, resulting in nonsense when used together. I'm guessing that CURRENTWEEK is handled like ISO week dates but CURRENTYEAR is Gregorian, resulting in weird behavior on this edge case. -PFWOz (talk) 19:02, 31 December 2018 (UTC)


 * Dug through some 10-year-old bug tickets and the workaround is to use . T18838:


 *  Use combination instead of  or 2024/. 


 * This should be made much clearer in the documentation, which suggests for more thorough time formatting, but not for improved correctness. Some details on how these magic words are calculated would help when trying to determine whether that's actually necessary. -PFWOz (talk) 19:07, 31 December 2018 (UTC)

False example for PAGENAME encoding of apostrophe
Help:Magic words shows an example which is currently false:

The code actually produces "No translation". Numeric char encoding to &amp;#39; does happen but #switch (same with #ifeq) will match &amp;#39; to any of ' (a pure apostrophe), &amp;apos; and &amp;#39;. The first match in the switch is chosen. "Show changes" on  will show that   produces L&amp;#39;Aquila if page name is "L'Aquila". It can cause problems in other situations. PrimeHunter (talk) 12:33, 12 January 2019 (UTC)

It is a wiki...

Anyway, when it was written it was 100% right, but things in the parser have changed since then, which is easy enough to prove by installing an older mediawiki version, or finding a public wiki, e.g. on wikia's wikis it shows "L&#39;Aquila". The only way to keep the example always true is to make it dynamic by identifying a parser function or lua function that will always match its behaviour, and transcluding that.

The rest of the comment is rather irrelevant, as far as the misguided "switch" parser function is concerned. It mostly follows the rules of programming languages, if multiple values match then it picks the first one, and that's clearly documented even for non-programmers.

Also, the warning comes with bug reports, so if any of them gets fixed it affects the example. So technically it isn't false.

Help:Magic_words - plural description should be more descriptive
- I think that plural description should be more descriptive: MarMi wiki (talk) 00:11, 14 June 2019 (UTC)
 * Is Form 1 a singular form of plural (then some more examples would be handy), or it's just a singular (only 1 single item)?
 * Is it only for words like is/are, or it's for singular (form 1, number 1)/paucal (form 2 or 3, numbers ending with digit 2-4)/plural (form 2 or 3, numbers ending with digit 0-1 [without number 1] and 5-9) forms of nuons (like Russian example may suggest [don't know Cyrillic/Russian that well])? (Numbers are for Poland).
 * Form 1 has numbers 1, 21, 31,... What about 11?
 * Does it even work on non-english sites? From my tests (based on is/are examples) it seems that it doesn't ( should return empty value, but it doesn't). Okay, it works on Russian wikipedia, but in strange way: returns are,  returns third. Shouldn't first return empty value?


 * As I wrote in edit summary, the description came from translatewiki:Thread:Portal_talk:Ru/Plural_changes_in_many_languages, so "21, 31, ..." should NOT be removed. It is written about some languages (ab, av, ba, etc.).
 * For example, English ordinal numbers have similar rule. 1st, 11th, 21st, 31st, etc. -Shirayuki (talk) 11:57, 14 June 2019 (UTC)
 * But what if it's not an ordinal number? Then it will work wrongly (in Polish): 1 szablon (template), 11 szablonów (templates), 21 szablonów (templates), 31 szablonów (templates), etc. Unless it's meant only for ordinal numbers (then there should be two magic words: ordinal and plural)? MarMi wiki (talk) 12:12, 14 June 2019 (UTC)
 * I think that plural description needs to specify if it's only for general broad singular/plural differentiation (jeden szablon/one template, wiele szablonów/many templates) or more detailed singular/plural differentiation based on numbers (1 szablon/template, 2 szablony/templates, ..., 4 szablony/templates, 5 szablonów/templates, ..., 9 szablonów/templates, etc.). MarMi wiki (talk) 13:10, 14 June 2019 (UTC)
 * Maybe someone knows where I can see couple of uses of this magic word in actual action? It would help to determine if it's fine as it is, or it needs some changes for my language.
 * Another note: is it choosing the mode depending on parameter count? Ex. 3 parameters (number + 2 words) - English (general broad) mode, 4 - Russian (more detailed) mode?. MarMi wiki (talk) 13:59, 14 June 2019 (UTC)

Summary of magic word plural after some tests: And I think Russian example needs to be updated - it doesn't match the order of numbers in Form 1/2/3. Russian example is correct - form 2 is in the third parameter (not counting the first number), and form 3 is in the second. Form order doesn't match the parameter order, which may be a little confusing. MarMi wiki (talk) 15:48, 14 June 2019 (UTC)
 * It's for simple one/many differentiation (English mode) AND for singular (form 1, number 1)/paucal (form 2 or 3, numbers ending with digit 2-4)/plural (form 2 or 3, numbers ending with digit 0-1 [without number 1] and 5-9) forms of nuons (given numbers may be wrong depending on given word) ("Russian" mode)
 * It works on Polish wikipedia (but numbers given in documentation for Form 1/2/3 doesn't match - they should be translatable too)
 * Used mode depends on number of parameters: number + 2 parameters (words) - simple English mode, with number + 3 parameters - advanced "Russian" (adapted to Polish) mode. MarMi wiki (talk) 14:49, 14 June 2019 (UTC)

Template name
Is there a magic word similar to that doesn't change when it's transcluded as a template? For example, say this magic word was called. If I created a template called, containing something like "This template is called ", it would transclude as "This template is called Title". I can't use for this, because it automatically changes to the page title. Gfdgsgxgzgdrc (talk) 00:31, 16 June 2019 (UTC)
 * I don’t know of any, but why would it be useful? is useful because the template can query the name of the page it’s used in—the template’s creator doesn’t know where the template will used. But the title of the template you’re just editing is known to you, so you can simply hardcode it. —Tacsipacsi (talk) 23:27, 16 June 2019 (UTC)

SUBPAGENAME : PAGENAME should be replaced by BASEPAGENAME for assertion to be coherent with display
Hi all, In paragraph https://www.mediawiki.org/wiki/Help:Magic_words#Page_names we use PAGENAME. On the FR translated page I get: SUBPAGENAME fr Titre de la sous-page ("bar" pour "Aide:Titre/foo/bar"). Si aucune sous-page n'existe, la valeur de est renvoyée. If I look at PAGENAME I read 'Magic words/fr' which is not coherent since I expect only 'Magic words' (as for EN pages).

Then Translations:Help:Magic words/125/fr should be: SUBPAGENAME 	fr 	Titre de la sous-page ("bar" pour "Aide:Titre/foo/bar"). Si aucune sous-page n'existe, la valeur de   est renvoyée. => Can anyone substitue the value of $code please using BASEPAGENAME instead of PAGENAME   ?

FR version displays: PAGENAME 	Magic words/fr 	Titre complet de la page (incluant tous les niveaux des sous-pages) sans l'espace de noms.

BASEPAGENAME 	Magic words 	Titre de la sous-page de niveau immédiatement supérieur sans l'espace de nom ("Titre/foo pour "Aide:Titre/foo/bar")...

SUBPAGENAME fr Titre de la sous-page ("bar" pour "Aide:Titre/foo/bar"). Si aucune sous-page n'existe, la valeur de est renvoyée.

Thanks.

I'm searching for a magic word or a function that can tell if a page or file is in a specific category. I have not found anything so far. --D-Kuru (talk) 10:36, 25 August 2019 (UTC)
 * This is because it could have unpredictable results in edge cases. Let’s say we have a such function named . What should the below code produce on the page “Page”?   If the page is in the category, the function returns nothing, so the page doesn’t get placed in the category, so the function returns the code placing it in the category, so it’s in the category, so it doesn’t get placed in it… —Tacsipacsi (talk) 15:06, 25 August 2019 (UTC)
 * Thanks for the fast reply!
 * I don't think that you need a specific output on the page itself (unlike eg. PAGESINCAT). I would have used just the return value (be it a boolean or a string) as some kind of the opposite of a template that includes a category. The use in my project would have been to check if file A.jpg is in Category:Hello and Category:Goodbye and if this is the case include a template, a warning, a category or whatever.
 * Your example would indeed be bad. You could display a warning though, when the function is used like that (like there is for template loops).

 * Do you want to use this feature on Commons or your own wiki?
