Square root and other questions
Hello,

I had 2 questions about the &#123;&#123;#expr:}} and the &#123;&#123;#ifexpr:}} parser functions: 80.230.37.167 14:38, 26 November 2012 (UTC)
 * 1) Is it possible to add a square root to those functions? using the sign √ in a formula doesnt work to me.
 * 2) Also, what do the != and the <> logic keys do?
 * Oh, i see that != make negative solutions possitive, but i still need the square root thing.
 * 80.230.37.167 14:49, 26 November 2012 (UTC)
 * ! in front of any conditional punctuation means NOT, so != is NOT EQUAL. As far as your question about sqr roots, you could build a (set of) template(s) like http://meta.wikimedia.org/wiki/Template:Root -- 141.114.97.70 15:08, 26 November 2012 (UTC)

 * Templates were never supposed to be some kind of "programming language", and the whole idea of Tim Starling's parser functions was to offer a faster alternative to template hacks ignoring this rule. State of the art is to use Scribunto math in the module namespace, if the parser functions are not good enough for your purposes. –Be..anyone (talk) 00:36, 13 December 2014 (UTC)

#time and full month names
Hi, I am apparently not seeing any indication of what any underlying support files are called.

The F operator returns a full month name, so 12 produces "December".

Which file houses the actual "December" string?

At my home wiki, it is returning the wrong string.

Thanks, Varlaam (talk) 05:41, 30 November 2012 (UTC)


 * On "my" wiki, I believe it uses MediaWiki:December and/or MediaWiki:December-gen, but I'm not entirely sure. If you would like to link your an example on your home wiki so I can see what it is returning, I would be happy to take a look and try to help you fix it. -- ShoeMaker   ( Contributions &bull; Message )   22:42, 2 January 2013 (UTC)

Test for existence of Month or Day in Date string?

  returns   returns I'm assuming you are hoping to use this as part of a template that will have values passed in to it, is that correct? If so, what is your list of arguments, what do you hope the template can do, and do you have a link to the template creation sandbox or wherever that you have started to make this so I can take a peek and hopefully understand what you want. -- ShoeMaker  ( Contributions &bull; Message )   22:52, 2 January 2013 (UTC)

Unwanted whitespace in article from #switch
I'm using a template whose entirety is just a switch statement to transclude one of two possible subtemplates. However, ParserFunctions seems to be adding an extra line of whitespace before the result of the switch statement when I use it this way. Is there a way to remove this whitespace?--Idran (talk) 01:46, 28 June 2013 (UTC)


 * Hello Idran. You should first check if the template adds the white space (line break). If you want to be strict on what gets transcluded via the template make sure you put everything that needs to be transcluded between  tags. Below an example.

Any Template documentation

 * Bla bla 1
 * Bla bla 2
 * Bla bla 3


 * If you don't do that you could easily transclude a line break to a page. --Jongfeli (talk) 08:34, 28 June 2013 (UTC)


 * I disagree with Jongfeli. en:Help:Transclusion has an informative section on how transclusion and the various include tags work.  Idran if you could post the markup from your template here, I would be happy to help you make it work as you expect.  I'm thinking the #switch might not be needed if there are only two outcomes and maybe an #ifeq would work better. Technical 13 (talk) 12:13, 28 June 2013 (UTC)


 * Actually while I was copying the code of the templates here, I noticed exactly what the problem was; I had an includeonly section in the subtemplates that I hadn't realized was adding an unwanted linebreak, and I didn't notice it because I was focusing my attention on the template itself.

 * Thanks for the answer. Now I got it, but in the current text, it is not clear that it only works for a single space.

 * Actually, on most wikis you have two problems with this attempt at an evaluation. First,  evaluates to   with an upper case B and second there is no "_". To workaround this, you need to use get the lowercase version of the pagename (   &rArr;   ), then you need to combine that with getting the Encoded version of FULLPAGENAME...   &rArr;  .

I've added a note that it strips underscores for spaces, as this actually is rather important behaviour if you want to use it in, say, an #ifeq - we don't want people putting in both cases for comparison because of an undocumented feature.þ

CSS selectors vs #ifexist
The documentation contains the following note of interest:
 * For some use cases it is possible to emulate the ifexist effect with css, by using the selectors  (to select links to unexisting pages) or   (to select links to existing pages).

Since #ifexist can be quite expensive indeed, I'd love to learn more about this. What are those use cases and how are those selectors used? Best, Cavila (MW 1.22, MySQL 5.5.37-0, Php 5.4.4-14 squeeze, SMW 1.9.2, SF 2.7) 07:57, 6 February 2015 (UTC)


 * In any case where you can use styling to achieve the effect you would have used #ifexist for. A missing page icon, for instance.
 * Also note that this is no more or less "expensive" than #ifexist (which is hardly expensive in the first place), it just simply doesn't increment the expensive parser functions count. --137.147.38.65 10:49, 6 February 2015 (UTC)

Remainder
Is it possible to use the #expr function to obtain a remainder from a division operation?

CycloneGU (talk) 18:38, 2 May 2015 (UTC)

UPDATE: I figured out another way to do it by using something like (that's  by the way), but I would still like to know if it can just be pulled directly so complex formulas don't have to be performed. I did it by using a floor, then remultiplying by the division number and doing simple subtraction. A remainder function would avoid this; I mean, seems so much easier and can be programmed like my example if not already present. It can then be documented. CycloneGU (talk) 20:29, 2 May 2015 (UTC)

Template user config files
It's funny why this statement has not been removed:

"# 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.]"

A switch can act as a template's configuration file ("to add info in one template... visible in several other templates"). The format of such a config file is a single switch statement in a subpage, called from the template. Because white space is ignored around the | and =, the subpage makes for easy grouping of configuration elements. Even if each line is displayed with a pipe, it is intuitive enough for editors to view or editing the set of template elements. With partial transclusion tags, the display of such a config file can render the switch statement in sections of case/result groupings, each with there own exposition and procedures.

Certainly the part about "all have different formatting" is unclear, because formatting is already provided by wikitext. "Processing" might be more accurate, but still too vague. How about "A #switch function with partial transclusion tags can effect a config file that enables any editor unfamiliar with template coding to view and edit template configuration elements. Examples include w:Template:NBA color, where any user can change the colors of a sports team, and w:Template:Val, where any user can add there own markup and link to the numeric units they want in their article."

Checking the existance of a section (I'm trying with #ifexist)
I need to get the information if a section with a regular name exists in a given page.

I've been trying to do that with, where <-- something --> was changed to a lot of things like #Section Name, #Section_Name. I've seen the function does not work with interwiki links but I couldn't figure out how to solve this problem.

The idea is to check if the page has evolved every time a new section is created (wich correspond to a new level). Each section should be named "Level 1", "Level 2" and so on.

I thought about using variables to do that too, but it seems it needs more effort to get thing running right.

If I can get this information, all the rest of my work can continue quite easily.

 When I write in the danish wiki, I will get correct local time (+01 in winter, +02 in summer). But when I write this in the faroese wiki, I will get winter time (+00) also when it should be summer time (+01). Can anybody help? Benadikt (talk) 08:16, 27 May 2017 (UTC)
 * Set timezone in preferences --wargo (talk) 08:41, 27 May 2017 (UTC)
 * No. Timezone setting should not effect the wiki content. This is because fowiki uses UTC timezone (like enwiki), which doesn’t have daylight saving time. You can ask to change it to an appropriate one (such as Europe/London) on Phabricator. Developers might ask for local consensus—changing timezone effects not only #timel parser function, but also the signature timestamps, history pages by default etc. --Tacsipacsi (talk) 09:53, 27 May 2017 (UTC)
 * Thank you very much, I will try to contact the administrators of fowiki first, and then Phabricator. Benadikt (talk) 10:22, 27 May 2017 (UTC)
 * Hello, I am administartor and Bureaucrat on the Faroese Wikipedia, we are only two administrators and there are not so many active users. I agree with Benadikt, we should of course use local Faroese time on the Faroese Wikipedia. I would be glad, if you could help us to change it. Kind regards --EileenSanda (talk) 13:34, 7 June 2017 (UTC)
 * Please gain local consensus – if there are few active users, of course you don’t need many votes. Just please leave a note on the village pump and give a few days for the folks to support (or oppose) it. This way your request will certainly not be declined. When the consensus is clear, I will help you post the request on Phabricator. --Tacsipacsi (talk) 18:47, 7 June 2017 (UTC)

#if test string is result of tag extension
I'm trying to use #if with the tested string being the result of a tag extension. In this case the test result always is "not empty" even when the extenstion returns an empty string, e.g.

The result is always "not empty" even when  returns an empty string. What's the problem? --88.217.31.114 12:32, 15 June 2017 (UTC)

Checked the result of the tag extension using #len:

The result is always "5", no matter what. But actually printing the result reveals nothing, e.g.

ab

results in ab5

What's going on there? --88.217.31.114 13:13, 15 June 2017 (UTC)
