Switches on templates - Please help

Hello. I'm a beginning wiki editor, and I have a wikia account which is just starting. I was wondering how to create a template that will categorize a page a particular way when asked. It's Guild Wars related, if you would like yo know. Here's how it breaks down.

There is a base template, say {{guild}}. I want it able to be discernible with several different categories. Something like {{Guild|PvX}} will automatically place it in the [[Category:PvX Guilds]]. At basic level, I would like to do so with these:

• PvE
• PvX
• PvP

It would be awesome if I could get subsets of each category too:

• PvE
  • Recruiting
  • Inactive.... And so on.

My question to you is how should I best do this? Thanks for listening. --67.119.193.93 (talk) 03:44, 7 August 2008 (UTC)

It's not difficult, for example this should do the basic job without the 2nd level ("Recruiting", etc.):

[[Category:{{{1|}}}Guilds]]

{{{1|}}} means "use the value of the first (un-named) parameter; if not supplied, output nothing". The disadvantage of this approach is that you have to remember the values, as the template doesn't check it.

I think a template is an unnecessarily complicated approach because you have to remember the valid values and code the template call {{Guilds|PvE}} correctly. Once you have the top-level category page, e.g. "Guilds", you could just put a link to it on your user page. Then you can look it up, copy the appropriate sub-category and paste it into the article. -- Philcha (talk) 05:02, 7 August 2008 (UTC)

you should also look through Parser Functions - the #switch: command might be useful for the kind of thing you're after. --Ludwigs2 21:53, 7 August 2008 (UTC)

Look at {{Non-free Scout logo}}. --—— Gadget850 (Ed) ^talk - 22:47, 7 August 2008 (UTC)

Hey cool, the switch works out for me - but when I try to place a second switch (recruiting = recruiting), the category gets messed up as "Category:RecruitingPvX Guilds" with the words jumbling together. Any way to fix this? Here's the code:

[[Category:{{#switch: {{{1|}}}|PvE = PvE|PvP = PvP|PvX = PvX}} Guilds]]

While the malfunctioning one is this:

[[Category:{{#switch: {{{2|}}}|Recruiting = Recruiting}}{{#switch: {{{1|}}}|PvE = PvE |PvP = PvP |PvX = PvX }} Guilds]]

Thanks. --People of Antioch (talk) 21:36, 8 August 2008 (UTC)

it's (again) not clear what result you're looking for here. remember, a category is just a wikipedia page that is used as a category list, and all you're trying to do with the switch is construct the correct page name character by character. so if what you've given above shouldn't have the words run together, then put a space in - e.g.:

[[Category:{{#switch: {{{2|}}}|Recruiting = Recruiting}} {{#switch: {{{1|}}}|PvE = PvE |PvP = PvP |PvX = PvX }} Guilds]]

it would really help if you could give an idea of the exact page structure that you're trying to reference. --Ludwigs2 00:44, 9 August 2008 (UTC)

Just a simple way of categorizing a page. It's located here. I tried spacing out the characters, but (it may just be a wikia thing) it doesn't seem to work out that way. I'm a little unclear on what you want me to clarify on, however (sorry!). --People of Antioch (talk) 02:38, 9 August 2008 (UTC)

PoA - I go to that page, and it doesn't say a darned thing about 'recruiting', 'inactive' or any other special page. you are telling us that the formula you're making doesn't create the right page names, but you are not telling us what the correct page names should be. basically you're saying "fix it, it's broke", but you're not telling us what 'it' is.

you can try using and underscore "_" or a non-breaking space "$nbsp;" instead of the space I used; that might work. --Ludwigs2 05:10, 9 August 2008 (UTC)

Oh! How stupid of me. It should be "Category:Recruiting PvX Guilds", "Category:Recruiting PvP Guilds", or "Category:Recruiting PvE Guilds". Anyway, the underscore worked out for me. Thanks for your help and the new bookmarks (cheat sheets ^_^) you gave me. People of Antioch (talk) 16:45, 9 August 2008 (UTC)

Hide/Show

I have a template which defaults to show and i'd like it to default to hide? Operating (talk) 20:51, 2 September 2008 (UTC)

errrr... can you be more specific? maybe a link to the tempalte would help. --Ludwigs2 22:01, 2 September 2008 (UTC)

Ah yes. Its here Template:Laurel and Hardy. It takes up a lot of room, and seems to be permanently on show. I've tried looking at it logged in and out of my account, to test whether it does default to show. Perhaps i'm missing something. Operating (talk) 22:32, 2 September 2008 (UTC)

I've fixed it. all it needed was the 'state=collapsed' parameter. --Ludwigs2 23:38, 2 September 2008 (UTC)

Ah good. Regards. Operating (talk) 23:47, 2 September 2008 (UTC)

Template:WP Criminal

I'm wanting to add a listas parameter to this template, as one does not exist on it at the moment, which makes it more difficult to manage as well as counter to other biography template functions. However, I'm totally clueless about how to edit templates. Help? Thanks! Wildhartlivie (talk) 00:06, 15 September 2008 (UTC)

what is this 'listas' parameter supposed to do? I have no idea how this tempalte is used, or what the change you're trying to make is. --Ludwigs2 01:08, 15 September 2008 (UTC)

It's a default sort function that is used in Template:WP Biography. The biography subject's name is put in the project template as listas=Dow, John so that it is properly alphabetized by last name in category listings. I'm not sure why Template:WP Criminal doesn't have this parameter, but it's routinely used on that project. Wildhartlivie (talk) 03:37, 15 September 2008 (UTC)

 Done ah, gotcha. I've added it in; may take a while to work its way through the system. if it doesn't work quite right let me know, but it should be non-problematic. --Ludwigs2 17:18, 15 September 2008 (UTC)

Thanks so much! Wildhartlivie (talk) 17:22, 15 September 2008 (UTC)

Template help

How might I make a template that does both of the following:
This:

{{TemplateThatNumbersNames|Joe|John|Mary}}

would yield:

Number	Name
1	Joe
2	John
3	Mary

while:

 {{TemplateThatNumbersNames|Joe|John|Mary|Sam|Sandra|Sue|Dave|Marcus Brutus}}

would then yield:

Number	Name
1	Joe
2	John
3	Mary
4	Sam
5	Sandra
6	Sue
7	Dave
8	Marcus Brutus

Basically, the template forms new rows for each new name, and numbers each new row accordingly. Is a template like this possible to create? Thanks for your help, αЯβιτЯαЯιŁΨθ ^(talk) 23:06, 29 September 2008 (UTC)

it's certainly possible to do this (there's a for-type loop template somewhere...) but I can't see the advantages of doing it. it would be just as easy to add in the rows by hand, or construct them using a good text editor and regexp. what's your bigger goal, here? --Ludwigs2 23:51, 29 September 2008 (UTC)

Thanks for asking Ludwigs2. I was hoping to create a template that could list and organize articles created by a user that is easy to use. I made one for myself, but as you can see, the source code is very long (about 5kB) and it is difficult to add articles onto. My hope was to create a chart like this through a template, by simply typing:

{{TemplateNameHere|Article 1|Article 2|Article 3|etc...}}

That way, it could easily be used by other users as well. So, in what way can this be done (refering back to my original question: {{TemplateThatNumbersNames|Joe|John|Mary}})? Thanks again for your help, αЯβιτЯαЯιŁΨθ ^(talk) 00:13, 30 September 2008 (UTC)

I may not be quite understanding what you're after, but it sounds like what you're after is a category page just for the articles you've created. either that, or a bot that will extract them out of your edit history...? let me give it some thought. --Ludwigs2 00:38, 30 September 2008 (UTC)

I used the code from Template:WikiProject Ships and tried my best to make some sense of it by editing out the bits i didn't need and replacing the pictures.

Help needed with parameter as if/else variable

Hi - hope this is the right place to ask. I've just made a template {{NZYearbook}} to use in reference sections for articles referencing the New Zealand official yearbook. I've used the year of the yearbook (which is published annually) as a parameter, so that it returns "New Zealand official 1977 yearbook"" (or whichever year. I'm also trying to make that parameter act as a if/else variable - the yearbook's publisher up to 1994 was the New Zealand Department of Statistics, from 1995 on it was Statistics New Zealand. I can't seem to work out how to make the parameter use one of these if it's 1994 or under, and the other if it's 1995 or over. Any help would be gratefully appreciated, thanks in advance. Grutness...wha? 09:13, 14 November 2008 (UTC)

Fixed, I think. looks like you might have had a non-breaking space (or seomthing like that) gumming up the works. --Ludwigs2 00:02, 29 December 2009 (UTC)

Problem with if scripts

I'm a user on the Danish version of Uncyclopedia ([1]). I've been trying to get this template to work in a few days, but somehow it just won't do as I want. It's meant to create a table with two rows and a picture to the right. In the upper row, there is going to be security marks for a product, while the lower row is going to have up to four columns with product descriptions.

The problem lies in the upper row, as the lower row already works. Se the result here: [2]

Here's the script (most of it is in English; only security mark descriptions are in Danish). You should look at the script of this page, as Wiki puts everything into one line here:

Template usage on Userpages

Hi, i've created a template at Template:TUGS-Member, to be placed on a user's userpage if they contribute to the TUGS WikiProject. For some reason, when this is done a message flags up telling me that the page should be moved to the user's talk page. But it shouldn't, that's not what its for. The only option round it is to add parameter "|category=no", but we don't want to do this either as this would remove them from Category:WikiProject TUGS participants - as well as mean that the user would have to add the category parameter on to the template every time it was added by a new user. Some examples of the template flagging up a problem can be seen at User:FelixCheng, User:Rusty5, User:PercytheGreen. What is the problem? --^{SteelersFanUK06} ReplyOnMine! 17:13, 20 November 2008 (UTC)

redirect to a template with the addition of a parameter

Hi. I made a new template called template:Infobox EU legislation, which is designed to merge template:EU regulation and template:EU directive. To make this merge come about I need some sort of a redirect from template:EU regulation and template:EU directive to template:Infobox EU legislation, but with the addition of another parameter ("regulation=1" for template:EU regulation and "directive=1" template:EU directive). The addition of the parameter is not a problem, but how do a forward the original parameters of template:EU regulation? I'm currently trying to establish something at template:EU regulation.

Various Cher templates

An editor has made a bit of a mess of templates for Cher songs and I can't quite sort it out. I'm not sure if he originally created Template:Cher songs, but he moved it to Template:Cher songs part 1 and also created Template:Cher songs Part 2. In the process, he also created Template:Cher singles (1965-1982)(navbox), which had errors, so he abandoned it (I've since nominated it for deletion). One of the problems, besides few of the songs in the templates having the template, is that with the templates on the Cher page when one clicks view on either template, it goes through a redirect from Template:Cher songs instead of directly to the correct template. Then today, he decides he wants to change the name of the Template:Cher songs Part 2, so he creates a new template, Template:Cher songs (1987-2009, which had an obvious error, so rather than request a name change/move the page, he created yet another new template, Template:Cher songs (1987-2009). Then he went in to the Cher page and changed the template name. I've nominated the new one with the error for nomination and redirected the second new one to the original Template:Cher songs Part 2. I changed back the template name on the Cher page to the orginal Part 2 template. The problem is, I'm overwhelmed. I don't know enough about all of this to fix the current templates on the Cher page so that one isn't redirected through the old, single template. When all of this is sorted out, I'll put the appropriate template on the song pages. Meanwhile, the editor split the Cher discography page into two separate pages, Cher singles discography and Cher albums discography but didn't changed the links in any of the templates (though I've fixed this).

Personally, I am not a fan of the ever-growing template farms at the bottom of articles. I'd be happy to dispose of the majority of the ones I see.

When parameters do not expand

Parameters do not get expanded when they are inside nowiki tags or XML-style extension tags.

Is there any sensible way to work around this? For example:

{{Template:Query|Q=rep_StockStatus}}

where the template code is:

<include nopre noesc src="https://my.domain.com/FetchData?q={{{Q}}}" />

which should expand to:

<include nopre noesc src="https://my.domain.com/FetchData?q=rep_StockStatus" />

but does not, the PHP code doesn't get parsed data, it sees https://my.domain.com/FetchData?q={{{Q}}}, which is pretty useless.

Kenpem (talk) 01:03, 4 February 2009 (UTC)

errr... I'm thinking that's probably not allowed by the parser. wikipedia pages don't allow certain kinds of HTML (mostly links and such) at all, and probably doesn't allow direct php code processing. this is to keeps spammers and hackers from hijacking links and pages for their own purposes. --Ludwigs2 01:40, 19 February 2009 (UTC)

Help with templates having seemingly erroneous symbols?

Not sure how to explain this, but what I can do is point you to, for example, Template:NBA game log section, which shows at the top this: |}
Now I'm wondering why that's there, since I can't find any mistake in the text of the template's article. And I've seen this in other templates and can't get rid of it - but I believe it should not be there. Please help! thanks ~ GoldenGoose100 (talk) 21:16, 1 March 2009 (UTC)

well, that particular construction looks like a broken table (those characters are how tables usually end). in the particular case of the Template:NBA game log section, it's because someone placed 'noinclude' tags around the opening {| of the first table. I have no idea why they would do that - let me see if I can straighten it out, and you can see the changes in the template page history. --Ludwigs2 21:51, 1 March 2009 (UTC)

ugh, well, it looks like this template was built by someone who doesn't 'get' portable code. what's happening (as near as I can tell) is that this template is of a set of connected templates, such that when all of them are put together they make one big table in the target article. start of the table is in one template, end of the table is in another, other templates have center pieces... ugly, ugly design, but I suspect it's way too involved to fix without a whole lot of effort. --Ludwigs2 22:01, 1 March 2009 (UTC)

Well... thanks for your effort in trying Ludwigs - peace ~ GoldenGoose100 (talk) 17:58, 2 March 2009 (UTC)

Looks like the <noinclude>...</noinclude> should have been <includeonly>...</includeonly>. The {| is not supposed to be part of the template, but the author wanted the table row to display neatly on the template page. Looks like the table header should be {{NBA game log start}}, then the table rows are built with {{NBA game log section}} and then the table is closed with {{NBA game log end}}. If you want to clean this up:

• Create a documentation page for {{NBA game log section}} and merge the documentation for all three templates
• Add {{documentation}} to all three templates, redirecting the other two to the first.
• Wrap all the templates in <includeonly>...</includeonly> so they look ugly on the template pages
• Create examples in the documentation

Templates like this are rather messy, but they do have the advantage of allowing neophytes to edit the article without understanding table code. --—— Gadget850 (Ed) ^talk - 18:36, 2 March 2009 (UTC)

there is that; but the programmer in me screams 'there has to be a better way'. ah well... --Ludwigs2 21:47, 2 March 2009 (UTC)

Easy template problem

#Restrictions on parameter values

For [4], it might not be necessary to mention any variations with named parameters, as this section starts out with unnamed parameters. Really minor point though.

Congrats to the re-writer of the page. Last time I was looking for something (here or on Mediawiki), I had a really hard time to find anything in the documentation.

BTW for version 1.2.6, wasn't it initially thought that, in general, templates were to be substituted? -- User:Docu

good point on the first; I'll fix that. and than you.

I don't know anything about the MediaWiki history, so... --Ludwigs2 01:25, 12 March 2009 (UTC)

Should references to "WikiMedia" be changed to "Wikipedia"? It reads "WikiMedia" as this page was written for/at m:Help:Template. -- User:Docu

eh, honestly I was thinking of moving big chunks of this over to m:Help:Template (since the original here was just a copy of that page anyway, and the issues are the same). I'd considered porting it to mw:Help:Templates, but HappyMelon seems to think that would violate licensing terms; plus, I'm having a hard time figuring out what the relationship between the three pages is supposed to be. . long story short, I said MediaWiki mostly because I was thinking in general terms as I edited. does that make any sense? --Ludwigs2 22:24, 12 March 2009 (UTC)

It does. It would be easier if we had just one version at mw:Help:Template. We'd spend less time figuring out which version is how outdated .. -- User:Docu

To include any work from here in mw:Help:Template, you must release your edits to Public Domain. A simple statement here will suffice. Another issue is that there are many differences between vanilla MediaWiki, the English Wikipedia and the Wikipedia sister projects.

DL Template Help

I am trying to edit this template in order to fix some redirects. Could someone please give me a hand and help explain how I would go about doing that?MusicInTheHouse (talk) 19:18, 18 April 2009 (UTC)

I'm not sure what you mean. do you want to merge this template with another template and redirect the other over? do you want to fix double redirects to this template? --Ludwigs2 21:24, 18 April 2009 (UTC)

There are links on the templates that link to redirects and other templates too. I just don't know how to edit templates and was hoping someone could quickly explain how I go about editing templates such as the one above. When I click on edit for example none of the countries or links appear just programming sentences or whatever they are. I appreciate any help then I'd be on my way.MusicInTheHouse (talk) 21:56, 18 April 2009 (UTC)

Ugh. I just followed one of the redirects back (Republic of Ireland, which redirects to Ireland), and fixing it directly is risky. what happens is that {{Driving licences in Europe}} calls {{Europe topic}} - a master template for those kinds of templates - and Europe topic calls {{Iso2country}} through a redirect from {{i2c}} to get specific page names for European country links. because of the way this is structured, changing the page name on the Iso2country template could make redlinks or break templates across a broad range of pages, and I don't know enough to mess with it. I suggest you leave a note on template_talk:Iso2country, or on the talk pages of one of the people that created that template. if you're having an immediate problem with double redirects, point me to where it's happening and I'll fix it, but anything more long term is going to have to come from them. --Ludwigs2 01:12, 19 April 2009 (UTC)

Thanks for the explanation. I didn't realise it was that complicated. I will do as you say, but as the main Republic of Ireland page is due to be moved soon I shall wait until that is sorted out until I ask people to fix it for consistency's sake.MusicInTheHouse (talk) 13:06, 19 April 2009 (UTC)

Help with an aspect of making a template

Hi, I hope this is in the right place! I recently made a template located here, and was wondering how I could make the three subsections of "Associates" align to the right, so that each sub-list begins un-staggered. I think that I have seen this used on templates before, but I could not find an example to copy when searching for pages I hoped would have complex templates on... Antienne (talk) 02:16, 2 May 2009 (UTC)

what do you mean by the three subsections of "Associates" align to the right, so that each sub-list begins un-staggered? I don't see anything I would call 'staggered' in the first place, and aligning the entire contents of that cell to the right would look... odd. please be as specific as possible in describing what you're after. --Ludwigs2 02:29, 2 May 2009 (UTC)

are you after something like this? --Ludwigs2 02:31, 2 May 2009 (UTC)

Hi, sorry for being unclear: I am trying to make it line up like edit I have made in the following image: http://img224.imageshack.us/my.php?image=97042928.png The coloured box is unimportant, but the example I recall seeing on WP somewhere I think used a coloured box like that. It is also unimportant whether the sub-headings are aligned to the right like the main headings, as long as the lists themselves all begin at the same point (evenly). I hope this is clearer.

Unquoting a parameter value

The 'lc' and 'uc' functions are very useful for changing case. Is there a simple method for removing quotes from a parameter value? Thanks! Plastikspork (talk) 21:09, 9 May 2009 (UTC)

easy one

I'd like to add an optional page parameter to a ref. template, {{SOWL}}. Help:Extension:ParserFunctions does not seem to cover this that I can see, though I'm probably only off by a pipe or two. Can someone take a look? Thanks, kwami (talk) 07:03, 11 May 2009 (UTC)

Could you give an example? Do you want something like {{SOWL|page=12}}? Checking the edit history, it looks like this problem has been resolved? Plastikspork (talk) 15:29, 11 May 2009 (UTC)

Yes, perfect. Could you tell me what the general function of the pipe in {{{1|}}} is? Thanks! kwami (talk) 16:18, 11 May 2009 (UTC)

Sure. In general, if you see {{{1|foo}}}, this will be replaced by the 'first unnamed parameter', if it exists, and foo if it does not exist. So, in your template, if someone writes {{SOWL|12}} then the {{{{1|}}} is replaced by 12. However, if they write {{{SOWL}}} then the {{{{1|}}} is replaced by nothing. You can do the same thing for "named parameters". For example, if you wanted to allow for {{SOWL|page=12}}, then you could use {{{page|}}}. And finally, if you wanted to allow for both optional methods for specification of a page number, you could use {{{page|{{{1|}}}}}}. The only reason for using named parameters would be if you wanted to have multiple options and didn't want people to have to specify them in the correct order. Plastikspork (talk) 18:51, 11 May 2009 (UTC)

Thanks! And here I was trying to work in #if. kwami (talk) 18:55, 11 May 2009 (UTC)

You could have used an '#if' statement, but that would have been unnecessarily complicated in this particular case. However, it could work to use something like {{#if:{{{1|}}}|{{{1}}}}}}, instead of {{{1|}}}. Plastikspork (talk) 20:59, 11 May 2009 (UTC)

Foreign exchange-rate converter

Does anybody know if one already exists to translate foreign currencies in articles into current USD equiv? I looked around but all I could find is one that just does it for Indian Rupees, and the template to describe FX markets (but not do any calculations). If there is not one for all major currencies, I'd like to take a stab at creating one... but I just don't want to spend a lot of time on it if there is already an established template.

I am thinking something like this in an article:

• Text in edit mode: ... the bridge cost {{fx|JPY|300000000000}} to build ...
• Text in article  : ... the bridge cost ¥ 300 billion (US$3.02 billion today) to build ...

The reason for the word "today" in the conversion results would be to make sure people knew this was not a static number, but may not be necessary if it seems obvious to everyone. I would use public data from the US Fed and update it weekly (hopefully automated at some point). Any/all feedback welcome.

• I think you're on a hiding to nothing creating piece of calculating algorithm to convert 1965 GBP into today CZK. Not only do exchange rates change on a daily basis, there's also the historical parities to consider (ie what measure to use to convert). Accountants have been stuck for ages not being able to agree what measures to use for converting "yesterday money" into "today money". I think we are better off sticking to what the sources say about measuring historical cost of things in today's money (or just static cost using the exchange rate prevailing at the time the event happened. Ohconfucius (talk) 08:35, 14 May 2009 (UTC)

• I hear what you are saying about historical exchange rate issues... but I was really hoping this would be a good excuse to jump into programming templates. Perhaps if it is more used for current/recent events and it is heavily disclaimered that it is based on direct current FX conversion, not counting inflation or TVM? Or still pointless? Also, one point to clarify, this was just going to be from foreign currency into US$ as is suggested currency to use in WP:$ - but your point is still just as relevant.    7   ^{talk | Δ |}   08:55, 14 May 2009 (UTC)

• I am biased towards static conversions. Quite often nowadays, a source will cite the local currency and a USD or EUR equivalent for any given transaction. If you had a magical calculating template, there is a risk that the calculated value may deviate from the source value- this could certainly be the case if the exchange rate used was dynamic (changing every day). I think we should forget trying to obtaing TVM/PPP type adjustments as being too problematic.

  Notwithstanding, technical issues which should be considered are burdens on the processing bandwith; the programming template must take into account when an event occurred, and then send that information to the enquiry database to choose the correct exchange rate, which will probably be a NY closing rate prevailing on that date (historical rate), any other rate would be meaningless. Of course, such data (even the very old) is now widely available, but we will be at the mercy of external databases; otherwise we would have to consider the impact on computing hardware WMF, so as not to be reliant. Ohconfucius (talk) 09:19, 14 May 2009 (UTC)

7, this is a great idea that, unlike many templates, isn't a solution in search of a problem. But before going further, let's be careful about the specs. First, is the idea to display any part in blue? If so, please think twice, because the result will be blue bits repeated throughout an article, which is tedious and not recommended by the style guides. Second, I think "today" is good as a nice, neat, short explanation—says it all. Third, weekly manual updating seems unduly frequent in these low-inflation days; I was expecting six-monthy or even yearly. Would there be a facility to limit the decimal places? US dollars today as the benchmark is fine by me. Please think of asking around a few WikiProjects for advice. MilHist and especially Hurricanes (damage done in previous years often converted) might be interested; I've reviewed many FA nominations that bring up the issue of equivalents.Tony (talk) 09:59, 14 May 2009 (UTC)

• Fabulous concept. I hope you can pull it off. Like Tony stated, it should generate black text.

  It would also need to have good error-checking so if a date exceeded the available historical range for one or both currencies in the conversion, it would immediately generate a big red-text error alert.

  How would it work? It could convert currencies to a historical index of “1” relative to some convenient date, like 1 January 2000. Then it would just divide the “to” currency’s factor by that of the “from” factor. I should think that data lookup tables would be impractical or impossible. So to be accurate, I would think that that historical currency data from tables would have to be described as variable-degree polynomials, like Y = Nx³ + Nx² + Nx + b. On second thought, scratch that; data lookup tables ought to be the way to go. Tables binned at yearly increments wouldn’t work well during periods of rapid hyperinflation, but I don’t see that is being a serious problem. All you would have to do is normalize each currency’s table to a “2000-equivalent” value and (again) divide the “to” currency’s 2000-equivalent factor by that of the “from” factor.

  Echoing a concern expressed by Ohconfucius, above: One potential stumbling block with this tool is it would take a knowledgeable shepherd to update the currency tables each time a new year’s data becomes available. Without such a person, such a tool would quickly grow to generate a lot of error codes. A work-around for such a shortcoming would be for the tool to not have an option to convert to a “today” value, but only to a specified date for which there is data; which is to say, it doesn’t generate an error code for the editor when they first try it. Such usage would look like The Germans spend ℳ5,100,000 on their V2 rocket (equivalent to $230,000,000 in 2008) (rather than “equivalent to $230,000,000 today”). It could be called “Historical currency converter” or “hcc”. Such syntax could look like {{hcc|germ-mark|5.1|1944|us-dollar|2008|2}}. The “2” at the end would stand for the significant digits to be used in the conversion.

  You could also go dollar-to-dollars or marks-to-marks, like this: {{hcc|us-dollar|2.1|1944|us-dollar|2009|2}} and the template would return the value “26”.

  For instance, one could code

  The U.S. spent $2.1 billion on the Manhattan Project (equivalent to {{hcc|us-dollar|2.1|1944|us-dollar|2009|2}} billion in 2009).

  …to generate this: The U.S. spent $2.1 billion on the Manhattan Project (equivalent to $26 billion in 2009). Super cool. I wish you well. Greg L (talk) 17:00, 14 May 2009 (UTC)

nothing like it in Category:Currency conversion templates. ---— Gadget850 (Ed) ^talk 17:17, 14 May 2009 (UTC)

• “7” (initiator of this thread): If you want to pursue this, I would suggest that you solicit a volunteer template author to code the smarts (which should be relatively simple). Your contribution would be to do all the “donkey work” (enter the tables). One thing you two would have to do is make it so it is easy (well documented) for “mere-mortal editors” to create subpages with tables for new currencies. Greg L (talk) 17:29, 14 May 2009 (UTC)

  P.S. Unless, that is, you are a template author yourself. I assumed you weren’t since you didn’t know if such a currency converter was already available. But, I don’t know if expertise in writing templates necessarily means that one must necessarily have familiarity with what all is on Wikipedia. Greg L (talk) 17:33, 14 May 2009 (UTC)

(←)Thanks to all for the feedback. I'm not a template programmer but was a geek (clipper, delphi, vc++, vb, sliverstream, etc...) in a prior life, so I will definitely seek support from others to make it a properly-coded reality. The more I think about this the more I think it may make sense to have two templates:

• one for straight FX (current or expected future cost): ... the bridge will cost {{fx|JPY|300000000000}} to build ...
• one for historical conversions : {{hcc|germ-mark|5.1|1944|us-dollar|2008|2}}

I realize people may say that this should be a single template (since you can accomplish the FX by using todays date in the complicated HCC template) but I've got two reasons why I think they should be separate: first - I think overly complex (# of parms) templates discourage users trying to accomplish simple tasks, and second -it will be a lot easier for me to get my feet wet coding the simple FX one first and it can be used as a base for the second. Will give it a start over the weekend and post in my user space for review / discussion. Thanks again.    7   ^{talk | Δ |}   00:57, 15 May 2009 (UTC)

Note, you can create a single front-end template to multiple backend templates. See, for example, {{convert}}, which is one of the more impressive undertakings. Plastikspork (talk) 16:30, 15 May 2009 (UTC)

• Or Table_of_nuclides_(combined) (l-o-n-g first-time load time). It is an extreme example of templates referring to templates. Greg L (talk) 01:07, 16 May 2009 (UTC)

Update:

(←)OK - here's a very rough draft. Clearly I'm no template pro, but most of it worked as expected. I haven't yet put the documentation in to a separate "doc" folder - but will do that shortly. Also, no real error checking in here yet (other than defaulted values where possible).

• Template draft: User:7/Template:fx

• Sample page with the template called for each currency : User:7/Template:fxtest

The good news is that I found this existing template:Inflation which can be combined with this simple FX template to make a Historical Conversion Calculator.

One thing I couldn't get to work was a sub-template to keep the rates separate from the code. For example, I have an excel macro that will easily pull the rates from the Fed's website and put them into this format: User:7/Template:fx/fxarray, and I was hoping that I could just put this {{User:7/Template:fx/fxarray}} into the middle of the main template code to have it transcluded (is that the right word to use), but it doesn't seem to work. Probably a simple fix. Any feedback or modifications are welcome. Thanks.    7   ^{talk | Δ |}   13:34, 16 May 2009 (UTC)

I was hoping there would be other comments in the meantime because I didn't want to be the first and last word on this subject. However, I still have some serious misgivings about the underlying concept and I really don't think you should spend any more time on this just yet. Even if such a template is adopted, I believe it needs to used with a great deal of restraint. On Monday, I will write a fuller explanation as to the inherent problems which I hinted at above. Ohconfucius (talk) 13:59, 16 May 2009 (UTC)

• Indeed. Ohconfucius and another editor recognized early on what the hazard was with User:7’s proposal. The issue of “when” is crucial in calculating conversions to other currencies. For instance, how can a Japanese Yen value quoted in 1988 be converted to USD using today’s conversion rate? I’ve unfortunately got a feeling that I am either galactically clueless or there is something amiss here. As far as I know, the only proper way to correctly do conversions is per the way I described with my “historical currency converter” method, above. It’s more than an issue of requiring the editor stick to the rigor of specifying a year for both the “from” and “to” currencies; this information is mandatory to pull off such a stunt without colossal-size errors often occurring. Greg L (talk) 03:15, 17 May 2009 (UTC)

• Ohconfucius gave me sound advice in the beginning about problems with historical exchange rates, and I respect that advice. His was the first, but was not the last comment as other editors chimed in that this could be useful. Therefore, and this is a key point, I think that the straight {{template:fx}} template can/should only be used in current and or future looking articles, and the second template (which is yet to be created, but I like the suggested name of {{hcc}} for "historical currency conversion") will use a combination of this current FX data and the template:inflation to inflate historical prices. If I am still missing the point then please clarify what risks remain. Thanks.    7   ^{talk | Δ |}   04:59, 17 May 2009 (UTC)

• That makes sense to me, User:7. Let’s see if Ohconfucius is seeing a problem with fx that we’re missing. Greg L (talk) 05:09, 17 May 2009 (UTC)

• I'm nervous that the template could be taken as a fait accomplis, rendering an accurate equivalent for quite different cost/price structures. The loaf of bread, by our conversion, might have cost $3 in Afghanistan in 1970, but a kilo of lamb $600. Who knows? At the very least, I'd like to see a recommended scope (in time and to and from which currency jurisdictions), in which the template's calculations might be safely used. Tony (talk) 08:44, 17 May 2009 (UTC)

• User:7 wrote of …current and or future looking articles… I’m not so sure about the “future” part. I think the only proper way to express an exchange rate is to always specify the date at which the conversion applied. For instance, one should write The Japanese government was planning on spending 70 billion yen in extra spending on new bullet train in 2009 (then US$730 million). Without a specific date, “current” and “future” soon becomes obsolete. Wikipedia is not supposed to have editorial content that rapidly becomes incorrect. I see nothing wrong with User:7 making what he is proposing. However, I think WP:MOSNUM will require some very explicit guidance on its proper use. Greg L (talk) 23:08, 17 May 2009 (UTC)

But that is better done with an explicit citation (for the conversion factor; multiplication is not original research) than by a template. Septentrionalis PMAnderson 02:13, 18 May 2009 (UTC)

• I tend to agree with you PMA. I see serious pitfalls with a template like this. An editor might be quoting a value from an event that happened in 2003. Then, when they use a template in authoring an article today, it would be using a conversion for 2008 or 2009. I just don’t think a template like fx—as currently envisioned by User:7—will work as a practical matter when you think about how editors in the real world will really use the thing.

  To User:7: Note that PMAnderson and I rarely see eye-to-eye on anything. That we have the same opinion on this should mean a lot to you. if you are intent on pursuing a currency converter, something as I described with “hcc”, which enforces chronological rigor with both the “from” and “to” currencies, is the only way I can foresee that a template won’t frequently be accidentally misused. Greg L (talk) 02:45, 18 May 2009 (UTC)

Your opinions do mean a lot to me, and I appreciate your feedback. I agree with all the points you have made, and I had thought about the maintenance nightmare involved with going around and looking for any article using the fx template where the article was over X years old for potential conversion to the hcc template.
As I said originally the two reasons for starting with the simple straight fx template were 1) simplicity for the user of the template and 2) tackling a simple template as my first one. Well, now 2 is done and template programming isn't so bad (but I still can't figure out my sub-template question above) but I still think point 1) simplicity is important. I know there are templates out there I am tempted to avoid because they take too many parameters. So, how about this to accomplish both simplicity and correct historical conversions:

• template:hcc will be created and will use template:inflation to PV the number and then use fx converting functions similar to what I have in the FX template now to change to US$. Any historical articles should use this template.
• tempatate:fx will be a subst template which is replaced with hcc template and the current year so that the user has a simple entry and it never becomes obsolete. Current/near-future looking articles can use this template. Then I only update the fx template once a year with the current year number and the users still get their simple template.
• Was also planning to incorporate a named ref tag at the end of the conversion referring readers to the template docs so they could understand the dates/times/rates used in the conversion.

And actually, as I write this, there is another pitfall that just came to mind. Technically I think the right way to represent this a historical foreign currency number would be to convert it to USD at a historical rate and then inflate it in the USD form. However I don't have easy access to historical FX data so the proposals I was writing above were to inflate in original currency per template:inflation and then to convert at current fx... That's not accurate at all. Any potential solutions, or is this a dead-end?.    7   ^{talk | Δ |}   03:14, 18 May 2009 (UTC)

• (←outdent). User:7: here is a US CPI table that goes back to 1913. Similar data is available—I believe—that goes back even further and averages the twelve months into a single value for a given year. Note also that Wikipedia’s own article on CPI has links to CPIs for other countries here. In my mind, the hard part in all of this is locating the best sources for each country’s data. From thereon, the process of creating tables and normalizing all the values to unity (1) for year 2000 is awfully straightforward.

  For a template to prove popular, it needs to be convenient and editors need to have confidence that their articles will look the same a year or two from now. Accordingly, one should convert as follows: The U.S. spent $2.1 billion on the Manhattan Project (equivalent to $26 billion in 2009). and should not write …equivalent to $26 billion today), because when 2010 roles around and User:7 has been hired by Microsoft and is too busy to horse around with updating a table on Wikipedia, the article would be incorrect in 2010.

  As for the concerns of Ohconfucius, below, he is a Wikifriend of mine so I don’t want to kick sand at his argument. I do see there is a “Manufacturer cost index in addition to a CPI. However, other countries have provide CPI for their currencies. For instance, Sweden has this CPI from 1290 to 2006. CPI seems like a sufficiently probative metric and the data is available for many currencies. I think this is doable and would be of benefit to Wikipedia if properly implemented. It is, however, no small undertaking and one certainly must be dedicated and meticulous to pull it off. Greg L (talk) 04:16, 18 May 2009 (UTC)

• "As for the concerns of Ohconfucius, below, he is a Wikifriend of mine so I don’t want to kick sand at his argument." I don't mind, Greg. This is all in the spirit of open discussion as there is no interest to this debate being one sided. The key is that our shared views here help to advance the cause. It may end up with something which works and is accepted once the concerns have been addressed. Ohconfucius (talk) 06:13, 18 May 2009 (UTC)

Counter-argument as promised

Prices move in relation to each other according to supply and demand - this is the classic definition of how the market mechanism works; the price of different things also vary at different rates through time. This is not to be conflated with link between the general trend of prices (as measured by the Consumer price index) and the money supply.

As prices may move differently, it is often appropriate to use different 'inflators' depending on what the subject is. You can see from a quick visit to this website that they give six methods/indices which could be used to calculate, for example, one of Handel's annual pensions (₤200 per annum in 1713) of USD $303 - equates to (at least) $8,342.30 in 2008 using the CPI-based calculation method, but turns out to be (at least) $157,100.91 in today's money using a wage-inflator. Depending on what benchmark is used for the adjustment because rates of inflation (or evolution of cost of living or purchasing power) may differ between countries or between categories of individuals, the 'adjusted value' may differ considerably. The Handel example illustrates my point very well, as the difference here is a factor of 18. It can be seen that we get a very wide ranging result for Handel's pension.

Paradoxically, the only index generally used to de/inflate is the retail prices index, which is based on a basket of commodities which reflect the cost of living. Even so, governments have been known to understate this for political reasons. Except in the most broad and general cases, the CPI will never result in the correct figure. There are official data about the cost of building houses, upon which house insurance calculations are generally based; if a reader wants to know the equivalent cost today of building a Dreadnought, or how much in today's money the QE2 cost, we would use a specific index for shipbuilding, instead of using the CPI.

Journalists and economists often compare then-to-now costs - we see these in newspapers often enough. Usually, such figures are pretty wild estimates which may vary depending on the hypotheses used. Physical storm damage is a real cost of repair/reinstatement can be measured with some accuracy; others are opportunity costs. It is here where we get differences of several orders of magnitude. I have no problem with comparative valuations as such so long as figures are sourced/attributed.

There are people armed with copious data and powerful algorithms who calculate such things for a living, so it's a can of worms for us mere mortals here on WP to decide, except on a very general level, and I don't trust the average WP editor to be able to be able to handle when such a template would be used.

Template/Switch question

Technical support question - Separate from the merits of the FX template in the discussion above, can anyone help me understand why this concept won't work for templates within templates. (would still like to understand why it doesn't work even if we decide the template itself is not that useful).

Question: For ease of maintaining lookup tables I wanted to have one template which contains the code and another subtemplate which contains the data that I am working with. It works fine when the data and the code are together, but I can't get it to work when the code just opens another template with double curly brackets for the data.

Here's an example:

• Template that works properly (with data included): User:7/Template:fx

• Sample output page with the template called for each currency : User:7/Template:fxtest

• Template that doesn't work (with data in separate file): User:7/Template:fx-doesntwork

• Sample output page with the broken template called for each currency : User:7/Template:fxtest-doesntwork (it is returning Not-a-Number because the switch formula is returning "undefined" which seems to be the only thing the switch formula can see when the other data is in a subtemplate.)

Not sure if this is a template question or a switch question, but I suspect a template guru will figure it out in about 4 seconds.

The reason I wanted to do it this way is that I have an excel macro that will easily down and format all the data that I need so that I can store/update it separately here: User:7/Template:fx/fxarray, and I was hoping that I could just put this {{User:7/Template:fx/fxarray}} into the middle of the main template code to have it transcluded (is that the right word to use?), but it doesn't seem to work. Any thoughts on how to fix? Thanks.    7   ^{talk | Δ |}   03:31, 18 May 2009 (UTC)

Question

Do you have the following possibility: including an article on a page, but with only a certain number of characters? --82.171.95.220 (talk) 15:52, 27 May 2009 (UTC)

I'm not sure what you are asking. Can you provide an example? Plastikspork (talk) 17:14, 27 May 2009 (UTC)

I think he may be talking about transcluding part of an article. We don't do this in mainspace for a number of reasons, but it is used for some portals. For example, List of counties of Lithuania uses content in <onlyinclude>...</onlyinclude> tags to show a portion on Portal:Featured content. Note that the portal pulls the featured items from a random list, so List of counties of Lithuania may not be the one that actually shows. ---— Gadget850 (Ed) ^talk 18:15, 27 May 2009 (UTC)

Is it possible to limit the number of variables that get processed or displayed?

The Video games project uses a template ({{VG reviews}}) to display reviews scores given by publications. Though it is not a requirement in articles, it is used in a large number of them. A common problem is that editors tend to include every review score they can get their hands on, basically bloating the table to impractical lengths.

My question is if there is a way to limit the number of scores that get displayed? For instance, if an editor inputs 11 or more scores, only the first 10 will show up. I realize that a set amount of numbered parameters could be used, but the current set up works rather well. Mainly because the current parameters properly format publication names and links.

Is such a thing possible? (Guyinblack25 ^talk 20:56, 1 June 2009 (UTC))

It looks like the template has rev1/rev1Score through rev8/rev8Score, limiting the scores to eight. This does not prevent someone from stacking scores in one set of parameters using breaks. If you want to reduce that number, discuss it on the template talk. ---— Gadget850 (Ed) ^talk 10:38, 15 June 2009 (UTC)

Actually those are meant to supplement the commonly used review sites like 1UP.com, IGN, and Nintendo Power. "Rev1"–rev8 would be for reviews from publications that are not commonly used, like newspapers and other media that is not gaming centered on video games.

There's about 50 possible publications that can be added to the table, which when all are used is too much. I'm looking to keep all the possible publications, but limit the number that will be displayed. If it's not possible that's ok, I'm just trying to see what the options are. (Guyinblack25 ^talk 14:35, 15 June 2009 (UTC))

Please review my changes

After these changes, I'd like to ask for review. This page should both give information to those struggling with the very concept of transclusion, and to those seeking the technical details. I'd place myself among those who grasp the basic concept well, but still grapple with the ancient mysteries...

So what I've done is try to explain how the parser lists template transclusions for any given Preview (i.e. it does NOT show which actual templates were called from the page/section you actually edited, instead it enumerates EVERY template invocation required to render the preview); how it acts when viewing a page from history (where I'm pretty sure it doesn't seek the historic version of the template and all sub-transclusions thereof) (and this was already alluded to in "Revision history of pages containing templates", way down there where most people would have long stopped reading); and a little discussion of what exactly the performance implications are, and the NewPP report.

These have all arisen in the context of the very complex {{convert}} template, which exemplifies almost all of the changes I've made.

My request here is for those more knowledgable to evaluate the factual accuracy of my changes; eliminate overlaps with "advanced" template help whilst still preserving links; and possibly creation of a separate section dealing with performance implications and the new pre-processor report in the HTML. Thanks! Franamax (talk) 23:48, 18 July 2009 (UTC)

Parameters to show a different text

I'm trying to make a template with several different outputs. For example, if you use {{Template | Date}} it will transclude 24 July, 2004, but if you use {{Template | Time}} it will show 13:04 specified by the template.

I imagine the template code itself would be something like:

| Date = 24 July, 2004

| Time = 13:04

Is there a way to do this? Smurfy 15:07, 19 July 2009 (UTC)

You can do something like this:

{{#if:{{{date|}}}|{{{date}}}|{{#if:{{{time|}}}|{{{time}}}}}}}

If the date parameter is non-blank, then show the date; else show the time if it is non-blank. ---— Gadget850 (Ed) ^talk 17:56, 19 July 2009 (UTC)

Adding text after calculation

How can I add a text, say unit miles, after the result of

{{#expr: ( 27 * 46 / pi ) round 2 }}

from with in the template? In other words, I want the template to return the word miles too as a part of its result in an article. — Preceding unsigned comment added by 76.69.90.229 (talk • contribs)

You can just write the word miles after the expression

{{#expr: ( 27 * 46 / pi ) round 2 }} miles

Does that work for you? Plastikspork (talk) 05:12, 23 July 2009 (UTC)

Yes it worked. Thanks! —Preceding unsigned comment added by 76.69.90.229 (talk) 23:03, 23 July 2009 (UTC)

Bar chart template

I would like to create a bar chart similar to this one on the Dutch wiki: http://nl.wikipedia.org/w/index.php?title=FC_Twente&action=edit&section=23

Can anyone inform me how to proceed with this? Does an equivalent template exist in English (copy & pasting the Dutch one doesn't work)?. Thx. --Wolbo (talk) 15:35, 29 July 2009 (UTC)

I translated it at User:Gadget850/Sandbox7. Had to replace "sjablooninfo" with the English version at {tl|Informative template}}, then the example uses "BalkVerticaal2" which is the actual template. Balk Verticaal trqanlates as Vertical Bar, but there is a different template there. Perhaps "Bar chart vertical" would be good. ---— Gadget850 (Ed) ^talk 17:49, 29 July 2009 (UTC)

Template trouble

A group/list template with more than 20 groups (Template:National personifications) won't show the 21st group. If this is a general constraint on group/list templates, what other kind of template could be used instead? RandomCritic (talk) 10:27, 17 August 2009 (UTC)

Yes, {{navbox}} has a limit of 20 groups. You could use something other than navbox, or split the box. Plastikspork _―Œ^(talk) 16:39, 17 August 2009 (UTC)

That navbox is really a long list; it could use some rework. ---— Gadget850 (Ed) ^talk 17:08, 17 August 2009 (UTC)

You could, perhaps, introduce subgroups, or make it two column? Or, perhaps just a bullet separated flat list. Plastikspork _―Œ^(talk) 17:42, 17 August 2009 (UTC)

Perhaps {{Navbox with columns}} would be a better choice. ---— Gadget850 (Ed) ^talk 13:55, 20 August 2009 (UTC)

Advice wanted for template

I have created a template, but for some reason it needs to be substd - otherwise if I put it on a user's page and they edit, it goes to the template page for editing! How can I amend the template so that it doesn't need to be subst'd?

The template is {{User:Phantomsteve/afd-notice}} and an example of when I use it can be see at User:Phantomsteve/Test-bed#section 2 for the un-subst'd version (if you click on "edit" for AfD for "test" article, then it goes to the template - I want to keep the header (I'm guessing that's where the problem lies)! User:Phantomsteve/Test-bed#section 2 is where I substd it - if you click on edit for AfD for "test" article, then obviously it'll edit the text on the page.

I've used other templates with variables which do not need to be subst'd, but they don't use level headers.

Any advice on how I can use this template without subst'ing it (or if I can be told definitively that it can't be done without subst) I would appreciate! -- PhantomSteve (Contact Me, My Contribs) 12:20, 20 August 2009 (UTC)

Help required

I have created template:lfc, to do a similar thing to template:fc when writing fotball club names. As women's football clubs, in the UK anyway, are usually Clubname Ladies, while their official and wiki names will be Clubname L.F.C. I'd like the template to also add 'Ladies' after the Clubname.

So for example, if I type {{subst:lfc|Arsenal}}, at the moment the template will give me [[Arsenal L.F.C.|Arsenal]], which is almost right, except I want it to give me [[Arsenal L.F.C.|Arsenal Ladies]]. Am a novice at this, so apologies if this is a really basic question, but hopefully someone can either show me how to do this, or just fix the template for me.

Thanks, 8lgm (talk) 16:18, 21 August 2009 (UTC)

Proof, I'm a novice I guess... My attempt is about to be speedy deleted as template:Lfc already exists and does the'almost there' bit. Would still like a further template to add the Ladies bit afterwards though. 8lgm (talk) 16:21, 21 August 2009 (UTC)

How do I get my signature to automatically expand in a subst:ed template?

I want to be able to subst a template and have it insert my live signature. However, if I put the code:

Never mind, I just figured it out. I need to use:

<includeonly>{{subst:signature}}</includeonly>

Template to mimic piped magicword

Hi all - I need some help with finding some way to mimic piping in {{PAGENAME}}. Is there any way either to use the magoc word or to create a template which mimics it so that it works in the same way as the pipe trick for article names?

For instance, say I wanted to start standardised stubs about small towns with the following titles...

• Xxxtown
• Xxxtown, Foo Province
• Xxxtown, Bar Province
• Xxxtown, Snert Province

...and wanted to have all of them start with the text:Xxxtown is a town in Flubbistan.

Towns without disambiguators, I could simply use PAGENAME; disambiguated names I'd need to find some way to stop the province name appearing in the article. Is there any way that PAGENAME can do that, and if not, how would I go about creating a template to do it? Grutness...wha? 08:18, 18 September 2009 (UTC)

I don't entirely follow what you are trying to do. If you feed the Xxxx to the template, you can always append the "town, Bar Province", and set up the piping that way. If you feed in the full name, then it's basically not possible to just grab the first part. When I say basically not possible, I mean without using some deprecated and less than reliable tricks. Plastikspork _―Œ^(talk) 20:57, 18 September 2009 (UTC)

It's the second thing I'd like to do. To put this in context, someone recently used a bot to create 800 articles on rivers in New Zealand. Some of them are simply in the form "Foo River", others - where dabbing is needed- are in the form "Foo River, New Zealand". I was wanting to "boilerplate" some standard information onto all of them, but can't use PAGENAME unless I then re-edit any with the disambiguator in the title. I was just looking for any way round that. If there isn't one, that's fine, I was just trying to save myself some work. Grutness...wha? 23:48, 18 September 2009 (UTC)

Are you trying to create a page with links to all of these articles, and you want to have piped versions for the ones which end in ", New Zealand"? If you point me to a page with all the links, I can run a script to pipe them all when necessary. Plastikspork _―Œ^(talk) 19:11, 19 September 2009 (UTC)

No - as I explained, I'm trying to replace the current text of the articles (one plain sentence: "The PAGENAME is a river of New Zealand") with a more detailed paragraph which reads "The {{Subst:PAGENAME}} is located in xx Region, in the xx Island of New Zealand. It runs xxdirection to reach the xxriver xx kilometres xxdirection of xx." It's easy enough to change the xxs before saving the article, as well as making any other necessary additions, but if the page title is disambiguated I need to save and reopen the edit window to change the piped name to the correct name. Grutness...wha? 22:06, 19 September 2009 (UTC)

I found Template:Title disambig text, which is kind of the reverse of what you want. I can't find something that automatically removes the disambig tag rather than extracting it, but you can cobble something together quite easily from Template:Str find and the other templates in that category. (Or I can run a script for you, if you supply me with all the data.)--Kotniski (talk) 15:32, 21 September 2009 (UTC)

I agree that the best solution is probably to run a script on all transclusions. The problem with templates like 'str find' is they aren't the most robust. Plastikspork _―Œ^(talk) 15:39, 21 September 2009 (UTC)

I was thinking they'd be OK for subst'ing, though of course that's another problem; you'd have to define subst'ing versions of any subtemplates that are in use. Looks like it's a job best handled by a script.--Kotniski (talk) 15:43, 21 September 2009 (UTC)

Thanks for the help and suggestions. I think I'm probably far enough through the task that trying to cobble things together would probably be as much work as the task I'm trying to avoid, though, so I'll keep doing it by hand. Cheers, Grutness...wha? 00:33, 22 September 2009 (UTC)

Indentation question

Resolved

 – with a solution to the original question! -- PhantomSteve (Contact Me, My Contribs) 16:22, 23 September 2009 (UTC)

Is there any way to make sure that a template keeps the current indentation?

For example, if I use :: {{user:phantomsteve/my-template}}, then all new lines within my-template are indented as per :: - and if I had a line in the template which was indented a level (e.g. : Indent this line) then it would be indented as if it was :::? -- PhantomSteve (Contact Me, My Contribs) 14:31, 21 September 2009 (UTC)

I rather doubt that this is possible.--Kotniski (talk) 15:33, 21 September 2009 (UTC)

If you want to keep the same level of indentation, then don't add indentation in your template? If you want to breakout of some indentation, then add a newline? Plastikspork _―Œ^(talk) 15:35, 21 September 2009 (UTC)

It seems the question is about keeping the level of indentation as defined outside the template as a starting point for the indentation of any new lines that occur within the template. People's ingenuity sometimes surprises me, but I would guess that you just can't do this.--Kotniski (talk) 15:39, 21 September 2009 (UTC)

It is possible, but you have to indent using a different mechanism. Basically, you use <dl> and <dd> for the indentation. To get it perfectly right, just look at the resulting html from : and ::. Plastikspork _―Œ^(talk) 16:21, 21 September 2009 (UTC)

Postscript - as I say, people's ingenuity surprises me (Plastikspork's in this case) - based on his suggestion, I seem to have got it working. (I can't imagine what this could be useful for, but still, good to know it can be done.) This is using User:Kotniski/Templatedemo:

Collapse/Uncollapse Help Request

I'm not sure where to seek out help with this so I'll try it here: On the Contemporary Philosophy entry there are 3 templates so they all collapse by default. Does anyone have a suggested way to make it so that the Analytic Philosophy template and the Continental Philosophy template remain uncollapsed by default. - Atfyfe (talk) 05:09, 14 November 2009 (UTC)

I assume you mean Contemporary philosophy, and are referring to the navboxes at the bottom? just add state = uncollapsed to each of then to have them open at startup. looks like {{Analytic Philosophy|state = uncollapsed}}

Fault-tolerant delimited list template?

Is there a template available that will create a delimited list out of its parameters, skipping any parameters that happen to be null? I've tried {{Linktext}} and {{do list}} but they both fail if the first parameter is null. For instance:

{{Linktext | pref=en | lim=, | | 2 | 3 | 4 }} produces the following:

[[en:|]], 2, 3, 4

Similarly, {{do list | delim=, | | 2 | 3 | 4 }} produces nothing at all because it stops once it hits a null parameter, as shown below:
Template:Do list

I'm trying to create a template that includes a comma-delimited list, and sometimes some of the elements of that list will be null (including the first item of the list). Any suggestions? Thanks! SnottyWong talk 22:04, 23 December 2009 (UTC)

Need some help with IF

Hello, I'd like to add a feature to add a feature to {{Infobox NFLactive}} but I'm not quite sure how to do it. That template chooses colors from certain templates—{{NFLPrimaryColor}}, {{NFLSecondaryColor}}, {{NFLAltPrimaryColor}}, and {{NFLAltSecondaryColor}}—based on the value of parameter currentteam. What I want is that for some teams (some values of currentteam), that template does not use the alt color templates ({{NFLAltPrimaryColor}} and {{NFLAltSecondaryColor}}) but only the main color templates ({{NFLPrimaryColor}}, {{NFLSecondaryColor}}). Which means that those lines (colspan="2" style="text-align:center; {{NFLAltPrimaryColor|{{{currentteam}}}}};" | <span style="{{NFLAltSecondaryColor|{{{currentteam}}}}};">Personal information</span>) have to have an IF-THEN, I think. How would that look like in code? --bender235 (talk) 13:10, 28 December 2009 (UTC)

easiest way to do this is with a bit of a trick. create a parameter called (say) 'usealt', and rewrite the line above as follows, so that the name of the template called becomes a variable:

colspan="2" style="text-align:center; {{NFL{{{usealt|Alt}}}PrimaryColor|{{{currentteam}}}}};" | <span style="{{NFL{{{usealt|Alt}}}SecondaryColor|{{{currentteam}}}}};">Personal information</span>

with this, {{Infobox NFLactive}} - where usealt is omitted - will insert the default 'Alt' and make the template call read NFLAltPrimaryColor; using {{Infobox NFLactive|alt=}} will set usealt to the empty string, and make the template call read NFLPrimaryColor.

haven't actually tested it, but it should work.--Ludwigs2 14:41, 28 December 2009 (UTC)

I was already aware of the way, but I don't want to use it because it means we'd have to change a couple of hundreds of player profiles on Wikipedia. I wanted to do it by just changing one template ({{Infobox NFLactive}} that is), implementing some sort of a if-then construct. Do you have any idea how to do that? --bender235 (talk) 14:54, 28 December 2009 (UTC)

Okay, I have an idea now, but I'm not quite sure how to programm it. I could create a seperate template with a #switch function, that returns "Alt" or "" based on the input parameter (that would be currentteam). Is that possible? --bender235 (talk) 23:16, 28 December 2009 (UTC)

Okay, I successfully programmed it on my own. This problem is solved. --bender235 (talk) 23:44, 28 December 2009 (UTC)
