 * I thought we didn't support Needed-Class anymore.  Happy ‑ melon  15:24, 29 April 2010 (UTC)
 * But what about all the subcategories of Category:Needed-Class articles? &mdash; Martin (MSGJ · talk) 16:07, 29 April 2010 (UTC)
 * And the subcategories of Current-Class articles, or Merge-Class articles, or any of the other custom classes?? Those classes which we said should be available for projects to use if they wish, but for which we should not bloat banner code for all projects.  There are 74 Needed-Class categories, 63 of which are empty.  I don't agree that we should make any move to better integrate these niche classes when that disadvantages 1,600 projects for the sake of less than a dozen.  Happy ‑ melon  21:31, 29 April 2010 (UTC)
 * Fair enough. I hadn't noticed that so many of them were empty. &mdash; Martin (MSGJ · talk) 10:32, 30 April 2010 (UTC)

talkspace=yes
I think a talkspace=yes, similar to subjectspace=yes, would be useful to have as an optional parameter for this template. It should, if on a talk page, return "talk page" and otherwise return the default value. This would be useful for templates like Last edited by to be more accurate or In use so we can get rid of the switch function there. --The Evil IP address (talk) 18:08, 6 June 2010 (UTC)
 * Sorry I can't understand what you mean. Can you describe the behaviour of the template with this new parameter? &mdash; Martin (MSGJ · talk) 18:46, 6 June 2010 (UTC)
 * Currently, on a talk page, this template shows the subject namespace, for example on an article talk page, it shows "article", on a template talk page it shows "template", and so on. However, there are situations in which it would be good to return "talk page" instead, for example within Last edited by. I'd like to add this template to Db-meta in the next time (which already uses a similar hardcoded function of this template), but since db templates are also used on talk pages, showing "article" or "template" wouldn't make sense there. --The Evil IP address (talk) 13:10, 9 June 2010 (UTC)
 * Ah now I understand. I would be open to such an addition if it can be coded cleanly without affecting the performance for the majority of uses (as this is a very widely used template!) Question: could you not just use  page  in your case? &mdash; Martin (MSGJ · talk) 15:36, 9 June 2010 (UTC)
 * Fixed by using Template:pp-meta/pagetype instead. Prodego  talk  23:59, 12 January 2011 (UTC)

Misleading documentation
According to the documentation there's a parameter "subjectspace - If set to yes then subjectspace pages will be treated the same as talkspace pages."

Without subjectspace: and  produce "" and "".

With subjectspace: and  produce "" and "".

There's an unnamed parameter, "class", but that's "optional" and the documentation suggests that it shouldn't affect the result in this case. Is the intention to require page name (which includes namespace) and namespace specified as separate parameters? Peter&#160;James (talk) 00:01, 22 September 2013 (UTC)


 * I've updated the docs to match what the template does. -- WOSlinker (talk) 00:15, 22 September 2013 (UTC)


 * It's still misleading. "This template is used to identify what kind of page it or its subject page is." - but when used with a page name, it returns "Article" for a template and "Template" for a template talk page. Is there something similar to Template:Pp-meta/pagetype (mentioned above) but allowing a parameter for page name? Peter&#160;James (talk) 08:02, 22 September 2013 (UTC)


 * This template was designed for use by WikiProject banners so it was mainly just tested on talk pages and currently doesn't do very well with non-talk pages. I'll have alook at doing something better in the sandbox soon. -- WOSlinker (talk) 08:33, 22 September 2013 (UTC)


 * I found it in use in Template:Edit protected and Template:Edit semi-protected, where parameter is needed because of a change to MediaWiki:Protectedpagetext. I've had to use TALKPAGENAME in those templates, which isn't ideal but produces the correct result (except in the unlikely event of a request for an edit to a redirected talk page). It may produce incorrect results if this template is changed, although it only affects the message and not the template's function. If improving or replacing this template, it may also be possible to use Module:Redirect to determine whether a page is a redirect, although it currently fails where "#REDIRECT:" (instead of just "#REDIRECT" is used. Peter&#160;James (talk) 10:12, 22 September 2013 (UTC)


 * Right, I've made some changes in the sandbox and now and  produce "" and "". I've also removed the subjectspace option from the sandbox since it's not needed with the changes that I've made. Can you give it a test yourself & if you are happy, we can make it live. -- WOSlinker (talk) 13:30, 22 September 2013 (UTC)
 * It's an improvement for pages not in talk or article space, and does what the "output" section of the documentation says, with the exception of "portal" or "project" class in subjectspace - is that needed? Peter&#160;James (talk) 15:08, 22 September 2013 (UTC)
 * I think that's fine. I've updated the template and the docs. -- WOSlinker (talk) 16:07, 22 September 2013 (UTC)

Module:Pagetype
I've created a Lua implementation of this template at Module:Pagetype. It's much more customisable than this template, and can be used to create other pagetype-like templates with different namespace configurations and custom text values. Have a look at the module documentation for details. The default settings are almost the same as this template, with one important difference - redirects are now detected and displayed as "redirect", no matter what namespace they are in. If this is undesirable I can change it, but it won't be easy to change the redirect detection on a per-namespace basis, due to the way the module hooks into Module:Namespace detect. Please have a look at the module, test it a bit, and see if there are any bugs, or anything you would like to change. You might also want to take a look at the test cases (results). If everything is ok, I plan to update pagetype with this module some time this week. — Mr. Stradivarius  ♪ talk ♪ 14:07, 4 November 2013 (UTC)

Misleading message about redirect
If you put on MediaWiki talk:Spam-blacklist, the box begins with "It is requested that an edit be made to the fully protected redirect at MediaWiki talk:Spam-blacklist/log.". Why "redirect", when MediaWiki talk:Spam-blacklist/log isn't? See. -- Red rose64 (talk) 18:54, 3 April 2014 (UTC)
 * The issue is that when p._main{page='MediaWiki talk:Spam-blacklist/log'} is called, checkRedirects instead checks to see if MediaWiki:Spam-blacklist/log is a redirect (lines 208-211). I'm not sure what the logic behind doing that that way is. Thoughts? Jackmcbarn (talk) 19:16, 3 April 2014 (UTC)
 * Yep, that's a bug in the module. It should use the current page rather than the subject page if talk pages are allowed, but at the moment it only checks args.talk, not args.defaultns.

 * You could either use or you could edit the cfg.defaultNamespaces section of Module:Pagetype/config. -- WOSlinker (talk) 11:56, 3 October 2014 (UTC)
 * Drafts are detected fine - they are one of the extended namespaces. See Module:Pagetype for a quick look at what is in what set. And if you think drafts should be in the default set instead of just the extended set, we can make the change in the module config, as WOSlinker said.

Plurals
Following a request at Wikipedia talk:Short description, which complained that the Short description naively pluralises 'category' as ' categories categorys ', I looked for a fix. As the template calls Template:Pagetype in three places, it seemed hugely inefficient to use logic to test for irregular plurals at each call, so I've implemented a boolean plural parameter in Module:Pagetype/sandbox. That makes use of a couple of extra variables that I've added to Module:Pagetype/config/sandbox (to allow localisation for other Wikis). I've set each respective sandbox to call the relevant sandbox. So: It seems to work without problem on each type of page, including redirects where I've previewed the above code. It fails the same four testcases at Module talk:Pagetype/testcases that were failing before (pages that are now redirects).

As I'm not familiar with the uses of the less common parameters (although there should be no interaction as I've coded the changes at the output of the main function), I'm flagging this up for review and to seek consensus for the changes to be made. --RexxS (talk) 23:16, 24 May 2020 (UTC)

Implement the change I've made at Module:Pagetype/sandbox; specifically, the addition of a caps parameter, that capitalises the first letter of the output. The change is very simple; below line 209, insert the following:

The indentation on the output above is... interesting... but the correct indentation is used in the wikitext.

You can see this working in the test cases, where I've written specific tests for it; it plays nicely with the plural parameter, as you'd expect. It is worthy of note that I've had to separately fix some of the other testcases, as the pages that they depended on have changed since the last time the testcases were used.

Please let me know once this is sorted so I can update the documentation for the new parameter.

 * The code works fine, but is there a use case for it? As an aside,  is a compact way of doing ucfirst (that's %'lower-case-L' in the pattern). --RexxS (talk) 20:27, 18 June 2020 (UTC)
 * The intended use case would be to have templates that either categorise pages, or link to categories of pages, shown correctly with the capitalisation of the first letter of the category. In the first case, which was actually what prompted me to propose this change, there's not much practical difference, because MediaWiki doesn't care about first letter capitalisation, and categories are processed through it. In the second, however, there's a visible difference for people looking at the link. It's no big deal, but it's a nice thing to have, and for the few lines of code it takes to support it, I figured why not Thanks for the tip about ucfirst - I'd not thought of just using a gsub, good shout!

The first is a dab while the second is an article. What am I doing wrong? --Gonnym (talk) 10:42, 2 July 2020 (UTC)


 * I don't think there is any way to check if a page is a disambig automatically, so what you are doing above is passing in the class value and because the class value you've passed is "dab", it outputs "page". If you have passed "start" for example then it would have output "article".
 * , which produces:
 * You can see what's possible against the Title object in the LUA reference manual and you'll see that there are items to check for redirects but nothing for disambig. Also see phabricator T71441.-- WOSlinker (talk) 13:42, 2 July 2020 (UTC)
 * Yeah I know there is no direct access, but I thought there was some backend manipulation the page content. So I'm not sure what the point is of the dab class. If I already know what the page type is, why would I send the page type, or even use this template in the first place? I feel like I'm missing something here. --Gonnym (talk) 13:51, 2 July 2020 (UTC)
 * A couple of hacks come to mind that could determine whether a page is a dab page:
 * Using a call to a Scribunto module that fetches the content of the page,, and then looks for the disambiguation template in it. Heavy and expensive.
 * If you're checking from Wikidata from an entity, use the fact that  returns false if the page is not a redirect; and   returns nil if the page has no Wikidata sitelink. If an article page has no Wikidata sitelink and is not a redirect, it is almost certainly a dab.
 * There are possibly others, but I'm not aware of any 100% guaranteed way that doesn't depend on some assumptions. --RexxS (talk) 15:49, 2 July 2020 (UTC)
 * , thanks. I've been looking into the page:content before I came here. Can you explain to me what's the purpose of the dab parameter? --Gonnym (talk) 16:04, 2 July 2020 (UTC)
 * There's more than just the disambiguation template to look for, there's some of the following templates that are also used for that purpose as well. -- WOSlinker (talk) 16:40, 2 July 2020 (UTC)
 * The main purpose of the Pagetype template is to be used on the project banners to show either "article" or "page" in the banner text. -- WOSlinker (talk) 16:33, 2 July 2020 (UTC)
 * As an example, if this template is used inside a WikiProject template, it can read the class parameter (passed into the WikiProject template) like this:  and then might be used to create a category name that the article should belong to, given that if the class is given as dab or n/a, the template will then return "page" instead of "article". There is the ability to specify custom text for either dab or n/a, depending on the naming convention required for the category name. Does that make sense? --RexxS (talk) 20:42, 2 July 2020 (UTC)
 * Yes, thanks! --Gonnym (talk) 22:25, 2 July 2020 (UTC)

 * I have implemented disambiguation page detection at Module:Pagetype/sandbox. At the moment, this still outputs the default "page" for disambiguation pages. Disambiguation detection works like redirect detection - it is on by default, and is checked before looking at defaultns or explicit namespace arguments. This means that if we are going to change the module to produce "disambiguation page" for disambiguation pages, with the current implementation this would be independent of the value of defaultns. (It can be done by editing the  value in Module:Pagetype/config/sandbox.) Using "disambiguation page" could be a breaking change for some users, as previously disambiguation pages specified by the first positional parameter have been output as "page". Before changing it, we should probably check to see whether anything is likely to break, and have a wider discussion. In the meantime, you can always change it on a per-template basis by using disambiguation page.  My edits to the sandbox have also removed the dependency on Module:Namespace detect, and I also changed Module:Pagetype/testcases to use Module:Mock title so that the test cases won't break if anyone edits any pages mentioned in them. Let me know if you spot any issues with any of this, and if not I'll go ahead and deploy the sandbox version to the main module. Best — Mr. Stradivarius  ♪ talk ♪ 07:34, 27 August 2023 (UTC)

 * I think changing the default would break too many things. Changing to automatic disambiguation page detection has already broken the categories used by Template:Short description, and it is difficult to tell what else might break by changing the default wording from "page" to "disambiguation page". — Mr. Stradivarius  ♪ talk ♪ 13:19, 29 August 2023 (UTC)
 * The WikiProject classification for some disambiguation pages such as Dragon Quest Heroes moved from being "NA-importance" by default to "Unknown-importance" as of today; since no change was made to Wikiproject banner shell, I think that this change may have affected that template/module. In looking at what moved and what didn't, it appears that "set index articles" are now no longer "NA" by default, while "normal" disambiguation articles are still handled correctly. I'm presuming that the fix needs to be applied to Wikiproject banner shell, not here, but replying here since there was an active discussion. -- Pres N  02:21, 30 August 2023 (UTC)
 * I tracked the problem down to Module:WikiProject banner. It uses Module:Pagetype here, and then compares the result to the string "article" here. This should probably be changed to a namespace check. — Mr. Stradivarius  ♪ talk ♪ 02:55, 30 August 2023 (UTC)
 * I think it's actually that Module:Disambiguation only looks for disambiguation templates, but set index pages have set index templates, so they don't get counted by the module as a disambiguation page, so Module:Pagetype is saying they're "article". Either Module:Disambiguation should treat those like disambig pages, or else Module:Pagetype should call a Module:Set index with its own regex patterns to handle set index pages. -- Pres N  11:48, 30 August 2023 (UTC)
 * Hm, you are right:  produces "article". This means that the recent change to Module:Pagetype won't have affected it (unless it was passing "dab" as the first positional parameter, which not many pages do). So there must be another reason for the change from "NA-importance" to "Unknown-importance". By the way, I don't think that set index articles not being detected as disambiguation pages by Module:Disambiguation is an error. From WP:SETINDEX: A set index article (SIA) is a list article about a set of items of a specific type that also share the same (or similar) name (italics mine). Also, there's an entire section WP:SETNOTDAB explaining that set index articles are not disambiguation pages. — <span style="color: #194D00; font-family: Palatino, Times, serif">Mr. Stradivarius  ♪ talk ♪ 13:26, 30 August 2023 (UTC)
 * Hmm. Given the definition and examples at that page (e.g. List of peaks named Signal), I see the argument for pagetype treating them as "article" rather than "disambiguation". I also don't think the pages I was looking at are really SIAs by that definition, but should be disambiguation pages. I'll adjust in that direction, and we can leave pagetype as it is. Still not sure what caused banner shell to stop treating them as disambiguation (I don't see anything in the code change that would cause it), but if its more correct this way then that's fine. -- Pres N  13:52, 30 August 2023 (UTC)

 * I'm still confused how it did, but there were some SIAs where the talk page template said "|class=Disambiguation" with no importance listed, and yesterday they moved from defaulting as NA-importance to being Unknown-importance. It was consistent on the 1.0 Bot assessment logs. It appears that the current state of things is the correct and intended way, and whatever was treating SIAs as disambiguation pages instead of lists was wrong, so nothing further to do here. -- Pres N  21:41, 30 August 2023 (UTC)

Detecting pages with Template:Wiktionary redirect and other soft redirects

 * Could you also add test cases to Module:Pagetype/testcases? There should be test cases there as well so that future updates to the code don't break the functionality you are adding. I designed the test cases so that you can specify an arbitrary "group name" (just a short description of the general kind of thing the test is testing), the arguments to the template, and the expected result. If you add more tests like that to the  table they should just work. Also, please add any titles you use in the tests to the   call at the top of the test cases and mock any fields that you will use. This ensures that the tests won't break if someone edits the actual wiki page in the future. You can see Module:Mock title for the different options you can use, but probably I guess you just need to copy the entry for "Alien" (a disambiguation page) and change the content. — <span style="color: #194D00; font-family: Palatino, Times, serif">Mr. Stradivarius  ♪ talk ♪ 00:26, 20 January 2024 (UTC)

 * Okay thanks. I suspect a bug in Module:Mock title rather than this module &mdash; Martin (MSGJ · talk) 16:38, 22 January 2024 (UTC)
 * I found the issue. You added the string  to Module:Pagetype/testcases, and as the module treats Module talk:Pagetype/testcases as the current page, it looks through the content of Module:Pagetype/testcases, finds that string, and assumes that the module must be a soft redirect. This wasn't a problem with disambiguation templates as the check for those was limited to the main namespace, but soft redirect detection is done in every namespace. I'm in two minds as to how to fix this. The obvious way would be to also check the page's content model before doing the template check, but checking the content model increments the expensive function count for pages other than the current page, which might cause problems in templates that depend on this module. The alternative is to exclude namespaces that typically have different content models, like module space, and userspace JS/CSS pages . This will be more of a pain to code and will be wrong for pages that have their content model changed manually, but it will avoid breaking dependent templates. I think the latter solution will be better, as I think there is a high probability of pages being broken by the increase in expensive function count if we choose the former. (This is just an assumption, however; I haven't checked in detail.)  While I am thinking about it, there is also a similar problem with <nowiki ></nowiki> tags; it is possible to write <nowiki >&#123;&#123;soft redirect&#125;&#125;</nowiki> on a wiki page, and this will not be parsed as a soft redirect, but this module will treat it as one. To avoid false positives in discussions etc. where people are talking about soft redirects, we should also detect whether template invocations are contained in <nowiki ></nowiki> blocks or not. — <span style="color: #194D00; font-family: Palatino, Times, serif">Mr. Stradivarius  ♪ talk ♪ 07:15, 23 January 2024 (UTC)
 * Actually, userspace CSS/JS pages should not be excluded, as they are actually categorised if you add a comment like  to them.

 * Thanks for looking into this. Alternatively we could just restrict the soft redirect detection to mainspace.

Sounds like a coder's nightmare! &mdash; Martin (MSGJ · talk) 09:04, 23 January 2024 (UTC)

Pages under discussion
When a redirect is proposed for deletion, it stops being detected as a redirect. Would it be possible to fix this, perhaps by looking for the literal text #REDIRECT on the page? There might be other cases, e.g. disambiguation pages too &mdash; Martin (MSGJ · talk) 11:47, 3 May 2024 (UTC)


 * Currently we just check if the title object itself considers the page a redirect for calculating that. Searching for just the literal string  by itself would be a bad idea (this page itself would pick up if we did that), and searching for #REDIRECT in the correct context probably wouldn't be a great idea for the same reason (easy to false flag). If the only issue is redirect pages that are under discussion, the simplest solution would be to just add a check for the RfD template onto the existing parseContent system, which shouldn't be difficult to implement. Does that sound like it'd fix your issue? Also, I'm unsure what you mean when you reference disambiguation pages. Aidan9382 (talk) 21:33, 5 May 2024 (UTC)

To do this, I think you would need to keep track of each title object that is altered when being hooked. I will have a think about how best to do this. At the moment, I think normal title objects which have mock titles hooked in one of their properties will remain altered after the patching function exits. Also, a similar hooking process needs to be implemented for Title.subPageTitle( text ), as that method returns other title objects.

I think I would prefer pagetype to identify this as an interface page rather than a non-existent page. &mdash; Martin (MSGJ · talk) 14:32, 17 May 2024 (UTC)
 * 1) MediaWiki:Filetype-missing - valid message but has not been created to override default
 * 2) MediaWiki:Duplicate-args-warning - has been created to override default
 * 3) Mediawiki:Fghghghg - invalid and non-existent


 * Perhaps  can be used to distinguish between some of these types &mdash; Martin (MSGJ · talk) 15:01, 17 May 2024 (UTC)
 * Proposed amended code on sandbox. A valid system message will be treated as an interface page even if it does not exist locally &mdash; Martin (MSGJ · talk) 09:34, 20 May 2024 (UTC)

Also added a fix for files hosted on Commons, which were being classified as non-existent pages. All testcases are now working, so will deploy this later &mdash; Martin (MSGJ · talk) 12:06, 21 May 2024 (UTC)
