Village Pump proposal for enabling this by default for most editors
Please see Wikipedia:Village_pump_(proposals)#Proposal:_enable_HotCat_for_all_editors_by_default. --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 02:56, 25 September 2012 (UTC)
 * The discussion has been closed, with the most popular option being: enable HotCat for all registered accounts. The discussants also liked the idea (if feasible) to add a confirmation page and/or a help page, to be displayed for first time editors who remove a category, to reduce a chance of an accidental mistake. --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 16:57, 2 October 2012 (UTC)
 * Hooray! I missed the notice the first time around, but am glad to hear there is consensus for broadly enabling this excellent gadget. Thanks for reporting back, Piotr! -Pete (talk) 22:11, 30 October 2012 (UTC)

Unfortunately, I don't know how to get in touch with the developers; somebody suggested starting a bugzilla report, but I don't think it has been done. If anybody knows how to contact the developers, please do so, I linked all the community discussions (including fixing archive links) above. PS. I've asked about this at the MediaWiki_talk:Gadgets-definition, as suggested at VP.--Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 17:35, 15 November 2012 (UTC)
 * Piotrus, HotCat is not part of the MediaWiki software, so opening a bugzilla bug won't help. I am its main developer and maintainer. It seems to me that the result of that discussion was "just turn it on for anybody who's logged in", without additional hassles like extra confirmation screens and so on. Right? If so, I think it's a simple configuration thing. Somebody just needs to add the  flag to it in MediaWiki:Gadgets-definition. I'll do it tomorrow morning (UTC) if nobody else has done so yet; I don't have the time right now, and I want to be present when that happens so that I can intervene if anything goes wrong. Lupo 18:14, 15 November 2012 (UTC)
 * On closer look, I see a number of people in that discussion who wanted an extra confirmation on category deletions. Hmmm... be prepared in this case to see the default enablement be undone if unmotivated category removals really turn out to be problem. Lupo 18:22, 15 November 2012 (UTC)
 * You are right that turn it on by default is the common vote, extra confirmation would be nice, but if it would delay the implementation of the turning it on by more than few days, I wouldn't worry about it too much. --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 19:19, 15 November 2012 (UTC)
 * Actually, I am in the camp of people who think that this one-click behavior, which is so convenient for experienced editors, is a trap for new editors. I will therefore enable it for all logged-in accounts, but I'll force non-autoconfirmed users to always go through the diff screen. That shows them the effect of what they do in HotCat, and it is saved only if they explicitly click the "save page" button. Strikes me as a simple way to teach the effects of various HotCat functions, and will help avoid the worst blunders. A new user becomes autoconfirmed if his account is older than four days and he has made at least 10 edits. After that, they'll have the one-click behavior. I do think that this is much better and avoids embarrassment for new editors, and it'll help avoid newbies getting bitten. Lupo 22:00, 15 November 2012 (UTC)
 * Fair enough. --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 01:08, 16 November 2012 (UTC)

Done now. Announcements left at WP:AN, WP:VPT, and at MediaWiki talk:Gadgets-definition. Lupo 09:03, 16 November 2012 (UTC)

Quick question?
Is this feature enabled by default (or did I somehow add it to my preferences without realizing it)? Bwrs (talk) 06:16, 10 January 2013 (UTC)
 * See above. Lupo 09:37, 10 January 2013 (UTC)

Can I use this on my own wiki?
I really like this feature and am wondering how it works, and if I can install it via MediaWiki:Monobook.js or is it an extension? Xtreme2000 (talk) 22:25, 11 January 2013 (UTC)
 * It's not an extension, just javascript. If you want to install it for your whole wiki, there are instructions at commons:Help:Gadget-HotCat.  If you just want it for your own use, you should be able to just copy commons:MediaWiki:Gadget-HotCat.js into your Special:MyPage/Common.js on your wiki. – Philosopher Let us reason together. 19:07, 12 January 2013 (UTC)

Confirmation screens, please
If is per-user configurable whether the new UI elements edit the page immediately or display some sort of confirmation screen? If so, please let the default be to show a confimation screen, independently of seniority. I saw strange new bluelinks at the bottom of a page, poked at them in curiosity to find out what they did and before I knew what was going on I had edited the page! I happened to be observant enough to check my contributions and rollback the edit, but even a small non-observant fraction of the who-knows-how-many autoconfirmed users could do considerable accidental damage, I think.

The common UI convention on the web is that blue links are harmless retrieval operations, whereas transactions that actually do stuff involve clicking on a button widget. Deviations from this pattern really ought to be opt-in. –Henning Makholm (talk) 01:39, 17 November 2012 (UTC)

Seconded: as someone who often browses on my slow touchscreen phone in an area with poor signal, I've just been delighted to discover how to hide the danger of one-click rollbacks from my watchlist. Confirmation screens seem an excellent way to avoid either fat-finger (/slow touchscreen) mistakes or ignorant confusion, with the option for confident users to disable them as a preference if they think fit. Pam D  07:13, 17 November 2012 (UTC)


 * Yeah, actually, I agree with you. I guess in particular the (-) link for category deletion is still a trap. The (+) link is not a problem, I think: it gives you an edit box, so it's rather clear that you will be changing something, and that edit box has a "cancel" button. I'll program something in so that the (-) link doesn't save on its own, but goes through an intermediary diff screen, where the user will have to explicitly click "save page".


 * It is actually user configurable. Put the following line into your common.js:


 * That will make all HotCat changes go through a diff screen. But as I said, I'll change the behavior of that (-) link. Lupo 09:37, 17 November 2012 (UTC)

✅. Clicking on the (-) link will now not save directly, but show an edit page, with the changes. The user has to explicitly save the edit. Note that due to the way all this gadget stuff works, it is perhaps necessary to reload your browser's cache to get the fix right away.

Experienced users can override this behavior and get the old "one-click-deletion" back by adding the following line to their common.js:

HTH, Lupo 10:55, 17 November 2012 (UTC)
 * Reasonable, but please add the tip for experienced user to the main HotCat how to page. --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 18:43, 19 November 2012 (UTC)

I'm not sure this confirmation stuff is working quite right. I just inadvertantly added a category to someone's Talk page using the hotcat widget (my intent had been to add a new section). I don't think I got a confirmation, or if I did, it certainly wasn't clear enough! jhawkinson (talk) 11:09, 18 January 2013 (UTC)

So it wasn't just me - someone did change the configuration! Can a developer please update the documentation accordingly? (Just added that line of script to my .js page.) – Philosopher Let us reason together. 18:41, 18 January 2013 (UTC)

Question
How do I get it so that when I edit multiple categories at once using the multiedit button, I don't have to go through the confirmation screen? I see that there is a section above for the "-" link which I have done, but I also don't want to have to confirm when using the multiedit link. StringTheory11 (t • c) 17:23, 19 January 2013 (UTC)
 * See, above. – Philosopher Let us reason together. 06:49, 20 January 2013 (UTC)
 * Hmm, that code doesn't appear to be working. It didn't change anything. StringTheory11 (t • c) 01:33, 21 January 2013 (UTC)
 * Oh. I know the base HotCat code and the base MediaWiki code have changed since then, so maybe the changes broke it.  – Philosopher Let us reason together. 06:08, 21 January 2013 (UTC)
 * Still works for me at User:GoingBatty/vector.js. GoingBatty (talk) 01:21, 23 January 2013 (UTC)
 * I copied and pasted the code for your javascript page and now it works. Maybe I copied and pasted wrong the first time or something. Oh well, it's working now. StringTheory11 (t • c) 05:10, 23 January 2013 (UTC)

Adding and removing categories
I just added the category "Archaeological sites on the National Register of Historic Places in Alaska" to the new Beluga Point Site with HotCat. When I then tried to remove the redundant category "National Register of Historic Places in Alaska", HotCat doesn't remove the category. Instead, it takes me to the edit screen and requires I Save Page manually to remove it. Is this the way HotCat is supposed to operate now? — Maile (talk) 19:48, 27 January 2013 (UTC)
 * Yes. See above. Was introduced when the gadget was enabled by default. That section above also tells you how to get back the one-click-deletion behavior in case you wanted that. Lupo 16:45, 29 January 2013 (UTC)

unblock
Can we get Category:Unblock blacklisted? As far as I can tell, it's only ever used incorrectly. --jpgordon:==( o ) 23:57, 27 January 2013 (UTC)
 * Hello? --jpgordon:==( o ) 17:18, 4 February 2013 (UTC)

Functionality disappeared
I'm not getting the HOTCAT function -- I'm not seeing the up and down arrows. I tried changing the line in my javascript page to the one shown, but it didn't help. Am I missing something? --Auntof6 (talk) 11:23, 8 March 2013 (UTC)
 * You added that to your monobook.js, so I presume you were using monobook? And you did make your browser re-load the Javascript after the change? Lupo 10:45, 11 March 2013 (UTC)
 * Yes, I use monobook. I cleared the cache, in fact this has persisted across multiple browser sessions. --Auntof6 (talk) 00:53, 21 March 2013 (UTC)
 * What browser are you using? Maybe this is something browser-related. Works for me in Safari 6.0.3, Chrome 25, and in Firefox 19.0.2. Didn't try any others now. Lupo 22:23, 21 March 2013 (UTC)
 * Ah, no, now I see it: the line "&lt;!-- importScript('User:Lupin/popups.js'); -->" in your User:Auntof6/monobook.js is causing this. That line is not valid JavaScript, anything after it will not be executed. Delete that line, and use "window.hotcat_use_category_links" instead of "var", then reload your browser's cache, and it should work. Lupo 22:29, 21 March 2013 (UTC)
 * I think I did what you said, but I'm still having the problem. --Auntof6 (talk) 10:09, 23 March 2013 (UTC)
 * OK, I figured it out. Thanks for your help. --Auntof6 (talk) 10:28, 26 March 2013 (UTC)

Page reload
Am I missing something or has the process changed? When adding a cat I thought it used to save without submitting a form and refreshing the page? Now it is going through a full page reload. I just tried it in chrome 12.0.742.112 and FF 5.0.1, both Windows 7 --CutOffTies (talk) 11:59, 29 July 2011 (UTC)
 * It always did that. Lupo 22:13, 7 August 2011 (UTC)
 * I would really appreciate if it didn't, and used AJAX instead. Gryllida&#9998;&#9997; 22:26, 29 March 2013 (UTC)

WP:FOOTERS violation
See. I don't think that HotCat should change the order of footers if the previous order satisfied WP:FOOTERS but the new order does not. -- Red rose64 (talk) 18:09, 3 April 2013 (UTC)
 * HotCat does not do that. Talk to the user who made the edit. (Note that users can do whatever they like on the diff screen.) Lupo 20:23, 3 April 2013 (UTC)

Non-existent cats
I don't think that HotCat should allow the addition of non-existent (redlink) cats,. -- Red rose64 (talk) 14:41, 3 April 2013 (UTC)
 * Why not? The extra 's' in that case probably was a typo by the user in the category editor. Lupo 20:28, 3 April 2013 (UTC)
 * Doesn't HotCat validate the input then? I was under the impression that it did, given this thread above. -- Red rose64 (talk) 20:46, 3 April 2013 (UTC)
 * To some extent it does. It even displays visual cues as to whether the category entered exists or not. But why should it forbid adding a non-existing category? Some people work like that; if they try to add a category and find it doesn't exist yet, they add it all the same, then click the red link to create the category page. Lupo 21:03, 3 April 2013 (UTC)

Why can't HotCat handle categories with dashes in them?
When I want to add a category using HotCat, I often copy-paste in the title of the category rather than typing it. But when the category title has a dash in it (as in Category:Germany–United States relations), that doesn't work - it pastes as the nonexistent Category:Germany-United States relations. Is it possible to add such categories using HotCat, and if so, how should I do it? Robofish (talk) 22:13, 6 April 2013 (UTC)
 * Category:Germany–United States relations has an N-dash as the "–". You apparently entered a normal minus sign "-". Unfortunately, the server's search engine does not treat these as equivalent, and last time I looked, there was no way to tell it to return results for both; so HotCat cannot display both in its suggestion list. (Unless HotCat treated this on its end and made several search queries to the server, one for "-" and one for "–", and if there are more than one dash, even more queries, one for every possible combination of dashes.)
 * HotCat also cannot handle this by simply replacing any minus sign by an n-dash before making the query, as that might also be wrong. Especially on other projects (remember, this script runs on many WMF wikis, not just here at the English Wikipedia) that use other typographic conventions.
 * If you enter an n-dash in the category editor of HotCat (or paste it, for instance by pasting "Germany–" (has an n-dash at the end) without the quotes), then HotCat will show the categories in its suggestion list, and will also enter the category with the n-dash.
 * The problem here is two-fold:
 * The English Wikipedia has decided to embed a nit-picky typographic convention in article titles. Although there should be redirects using plain dashes (minus signs) to the "real" categories using n-dashes, it appears that this isn't always the case. If there are such redirects, then the categories could be found by humans and by HotCat irrespective of whether the user types a dash or an n-dash; and HotCat would even resolve the redirect and enter the category with the n-dash, as desired. For Category:Germany-Japan relations, there is such a redirect, so if you enter "Germany-Japan relations" (with a dash) in HotCat, it will actually add the category Category:Germany–Japan relations (with n-dash).
 * The server's search engine doesn't treat the various dashes as equivalent. Maybe someone should open a bugzilla request to ask for this.
 * As for your particular pasting problem, I have no idea where that comes from. HotCat certainly doesn't replace n-dashes by dashes or anything like that. In fact, I just pasted the category name Category:Germany–United States relations from (a) this wiki page, selecting part of the link, (b) going to that category page and selecting the category name from (b1) the browser's address bar, (b2) the page title on the category page. In all cases, the n-dash was correctly pasted, and HotCat would also insert the category with the n-dash. I also double checked that the redirect case (Germany-Japan with simple dash) does indeed work: it does.
 * Lupo 12:39, 7 April 2013 (UTC)
 * BTW, the normal search box you see on every Wikipedia page also has problems with dashes vs. n-dashes. Entering "Category:Germany-" (simple dash) doesn't show me any category containing a dash; all results start with "Germany ". Entering "Category:Germany–" (with n-dash) does show the true categories starting with that prefix. Lupo 13:26, 7 April 2013 (UTC)
 * See also the section on en-dashes above. Lupo 13:28, 7 April 2013 (UTC)

DEFAULTSORT
Is there any way to set HotCat so that DEFAULTSORTs can be added?Naraht (talk) 16:07, 11 April 2013 (UTC)
 * HotCat contains no code dealing with DEFAULTSORTs. The only way to make it offer support for editing/adding DEFAULTSORTs (or its localized variants) would be to write such code, which I don't have the time for. Lupo 10:09, 16 April 2013 (UTC)

Navbox problem with HotCat?
Apologies if this has been queried before, I couldn't see it on a quick scan through earlier discussions... I note that HotCat doesn't seem to work with my browser when there is more than one navigation box template at the bottom of an article (and sometimes not when there is just one). Is this a known bug? I realise my browser is not the newest (Safari 5.1.7) but I would expect it's new enough that others will be facing the same problem. Thanks in advance... Grutness...wha?  01:52, 24 April 2013 (UTC)
 * Never heard of that. Got an example page? And what does "Doesn't seem to work" mean exactly? Lupo 06:00, 24 April 2013 (UTC)

Le Mouv' is a perfect example. By "doesn't work", I mean the categories alone are listed at the bottom - no [-], [+], and [±] buttons, so if I want to add categories I have to physically edit the last section of the article. Please compare the attached images. Grutness...wha?  12:46, 24 April 2013 (UTC)


 * Works for me (Safari 5.1.7 on MacOS 10.6). Note that the first four categories in Le Mouv' are transcluded anyway. But your screenshot shows that the "(++) is also missing, so it's clear that HotCat didn't load for you. However, I cannot reproduce this. Is there anything in Safari's error log relating to JavaScript? (I do get two errors about 404 responses on monobook/bullet.gif and chick/main.css, but these are unrelated.) What other gadgets do have enabled? Lupo 13:17, 24 April 2013 (UTC)
 * BTW, the two navboxes are shown collapsed for me, not expanded. Collapsing is done, AFAIK, also via JavaScript, so it seems the Navbox-JavaSCript also doesn't load for you. Or did you expand them manually?
 * I would start with blanking User:Grutness/monobook.js I don't trust ANY of those contents at this moment. —Th e DJ (talk • contribs) 19:17, 24 April 2013 (UTC)
 * Ha! Blanking monobook.js seems to have done the trick. The main thing in there hasn't worked for a while anyway, so it's no loss. Thanks! Grutness...wha?  01:13, 25 April 2013 (UTC)

Catdiffuse
Can categories which are supposedly to be diffused be removed by default from appearing? – H T  D  18:59, 27 April 2013 (UTC)
 * HotCat currently has only a blacklist to exclude some categories from its suggestion list by name. (The blacklist is a single regular expression.) Doing category exclusion based on the content of a category page (such as it containing special templates) is currently not implemented and is be possible only at the cost of additional calls to the server, which will slow things down. Lupo 19:34, 27 April 2013 (UTC)
 * Well I guess that's fair enough. – H T  D  17:17, 28 April 2013 (UTC)

Problem!
Hey, I love your tool, especially when it provides a drop down (or roll up?) menu of possible Category names.

But I'm running into one problem: I often remove Categories that are supposed to be applied to Wikipedia Pages but, for some reason, are applied to User Pages (for example, Category:Wikipedia_templates). But when I tried to remove the Category from a User Page (User talk:Huangcjz for example), it is not possible to remove it, there is only the possibility to add new Categories. I went into Edit for the page and when I scrolled to the bottom of the page, no Categories appear at all, so I couldn't delete it that way either. I'm mystified but this has happened to me on other Pages, too, the inability to remove Categories while there is the ability to add new ones.

FWIW, when I've remove a misapplied Category, I leave a note to the Editor. It's just confusing, if you are looking at the Category page, to find User Pages mixed in with Template pages. Thanks for any help you can provide! ;-) Liz  Read! Talk! 21:57, 25 August 2013 (UTC)
 * HotCat is only enabled in certain namespaces - it would be great if someone could list them on HotCat. GoingBatty (talk) 01:03, 26 August 2013 (UTC)


 * You can't use HotCat to fix this problem. The fix is more complicated. Most of these user pages are in Category:Wikipedia templates because they transclude a template or other page that is in that category. For example, the page you gave as an example User talk:Huangcjz, transcludes WikiProject London Transport/The Metropolitan/Issue 16. That Wikipedia namespace page in turn transcludes Portal:London Transport/Selected pictures, a page in Portal namespace. That, in turn, transcludes Portal:London Transport/box-header-plain. That, in turn transcludes Template:Box-header-plain (Portal:Box-header-plain redirects there). Aha! Now the culprit has been tracked down: the first line in Template:Box-header-plain was Category:Wikipedia templates. Moving the category to the bottom, as I did with this edit, did the trick, because that put the category inside the  . . .  tags. Now, there's one more thing to clear specific pages like User talk:Huangcjz from the category right away: make a null edit to the page, to purge the page's server cache. The last step is optional, as the system will automatically purge its cache eventually. Thanks for pointing out the problem. Cheers, Wbm1058 (talk) 14:24, 26 August 2013 (UTC)

Keyboard shortcuts
Is there a way to click the (+) symbol with a keyboard shortcut instead of having to click on it with the mouse? It would be really great if there was. Ithinkicahn (talk) 19:20, 30 September 2013 (UTC)

Not initialising for pages without a category
When I load a page without a category, HotCat doesnt initialise. e.g. User:Kmccark. Special:NewPages is another source of pages like this. e.g. Rahman Mostafiz right now. John Vandenberg (chat) 01:18, 8 November 2013 (UTC)

Odd issue

Improve categories

Problem with FF29 when HotCat and WikEd both enabled
There is a problem being reported at User talk:Cacycle/wikEd which might be HotCat related. Thincat (talk) 22:11, 9 May 2014 (UTC)
 * Known problem; is being worked on. See Village pump (technical)/Archive 126. Might take a little while; we'll have to figure out how to best avoid the conflict, and where to fix it: in wikEd or in HotCat? Lupo 22:16, 9 May 2014 (UTC)

Hotcat not working (again)
Hi, I was trying to use HotCat recently but discovered that the categories at the bottom of every page I look at don't have the pluses and minuses next to them like usual, making it impossible to use HotCat. Also, I have it turned on in my preferences, so I know that's not it. Does anyone know why this is happening or if it has also happened to them? Jinkinson  talk to me  18:45, 16 May 2014 (UTC)
 * Nvm, it's working again. Jinkinson   talk to me  19:24, 16 May 2014 (UTC)
 * See WP:VPT. BTW, it's not just here, I also briefly lost all gadgets at the Commons. Lupo 19:29, 16 May 2014 (UTC)

Check/X icons for existence when adding a cat not distinct
The / icon next to the input box is an important indicator. When working quickly, it's easy not to notice that it's an X (and therefore to add a redlink due to typos or autocomplete not having caught up) rather than the checkmark. One quick improvement would be to make these more visually different from each other: maybe red vs blue background instead of both purplish? A functional improvement would be a confirmation dialog if one is adding a cat that doesn't exist, and to offer to open it in the wikipedia editor so one can create it. DMacks (talk) 15:31, 23 June 2014 (UTC)
 * For example, P no red.svg/P yes green.svg are more obviously different. I think red/green are not accessible as a difference, so P no red.svg/P yes.svg would meet that UI guideline. These icons are the only indication of a status, so it's important to keep them as accessible as possible. The current ones are also a problem for low-visibility users) and also don't use alt-text to indicate what they mean. DMacks (talk) 16:13, 23 June 2014 (UTC)
 * That can be configured. Just set in Mediawiki:Gadget-HotCat.js/local_defaults, and then HotCat should use the red icon. Lupo 18:52, 23 June 2014 (UTC)
 * Thanks! . DMacks (talk) 19:19, 23 June 2014 (UTC)

Layout in relation to stub tags
Would there be a practical way to make HotCat place categories before stub tags rather than after, as prescribed at WP:STUB? This may only be a problem for uncategorized pages. I came across it when placing a category on an uncategorized stub, and I had to manually put the category tag in the right place. Perhaps this wouldn't be practical, however, such as if HC couldn't distinguish between a stub tag and a navbox. --BDD (talk) 21:48, 3 April 2014 (UTC)
 * Not practical. First, I don't have the time to do larger code modifications, and second, it would need to be configurable because HotCat is used on many wikis, and they all may have different guidelines. Lupo 20:57, 23 June 2014 (UTC)

Prevent adding certain categories?
Is there any way to tell HotCat that particular maintenance categories should not be added to pages directly, because it is preferred to use a template that includes the category link? For example, if you read the description page for, one of the first things you see is a big bold notice asking you not to add it manually to any pages, but to use Disambiguation instead. However, HotCat users generally don't look at the category description pages and don't see this notice. So, is there any way within HotCat to prevent users from adding this category and similar maintenance categories? --R'n'B (call me Russ) 21:37, 20 May 2014 (UTC)
 * Yes, HotCat has a blacklist. See the help page. It could be configured here at the English Wikipedia to exclude such categories. Currently, only stub categories are excluded. Lupo 15:42, 23 June 2014 (UTC)
 * Thanks. I take it the relevant line is . Would there be any objection to changing it to  ? --R'n'B (call me Russ) 15:52, 23 June 2014 (UTC)
 * Not from me. That's fine. Lupo 18:48, 23 June 2014 (UTC)
 * BTW: what about Category:Airport disambiguation? Maybe you have to include that, too. But make sure you don't blacklist Category:Disambiguation categories: that one is already handeld by HotCat. Lupo 18:57, 23 June 2014 (UTC)
 * I think I'll just start with "... disambiguation pages" for now and see. I haven't seen the airport category causing any problems (yet). --R'n'B (call me Russ) 19:05, 23 June 2014 (UTC)
 * That's fine. Actually, I think Category:Disambiguation categories could be blocked, too. HotCat uses that one differently, but we don't want users to add it explicitly. But that'd be low-priority; it's just one category. Lupo 20:55, 23 June 2014 (UTC)
 * Since there are several disambiguation categories, how about excluding any category with "disambiguation" in it? GoingBatty (talk) 13:13, 5 July 2014 (UTC)
 * For that matter, every category in Category:Wikipedia maintenance categories sorted by month and Category:Wikipedia categories sorted by month (and most of the direct subcategories of those categories) shouldn't be added by HotCat. Anomie⚔ 11:29, 8 September 2014 (UTC)
 * Not easily doable, especially since those are whole category trees. Lupo 15:37, 8 September 2014 (UTC)

Unicode control characters
Hi, sometimes, a category is added with an extra invisible Unicode Control character (like Left-to-Right mark) at the end of the category name. Would it be possible to automatically remove it in HotCat ? Example: Joseph Brodsky (fix). --NicoV (Talk on frwiki) 12:41, 5 July 2014 (UTC)
 * That might be difficult to do correctly, and might need to be configurable per wiki. While page titles (and thus link targets) as stored in the database cannot contain BiDi overrides and strange Unicode spaces, links as written in the wikitext may contain such characters. Consider the following examples:

‫ لغة C++ هي لغة برمجة تستخدم...

‫ لغة C++&lrm; هي لغة برمجة تستخدم...


 * (Examples taken from Left-to-right mark and modified to use links.) Both links go tho the article C++, but the second does contain an LRM at the end. So, in general I think it would not be a good idea if HotCat tried to remove any of these invisible characters in the wikitext. It already does handle those characters when looking for categories in the wikitext, but for insertion, I fear that removing such things might lead to unexpected display issues. Lupo 12:20, 7 September 2014 (UTC)
 * Hi. I forgot to add this page to my watchlist, so I didn't see your answer earlier. I understand your explanation, I wonder if it applies to categories or not. Apparently (according to this discussion), it often happens that unnecessary LRM are added when copy/pasting category names with HotCats. --NicoV (Talk on frwiki) 15:41, 2 October 2014 (UTC)

Not working in Firefox
A few days ago HotCat stopped working for me in Firefox; it still does so in Chrome so it's not account-specific. I am still using F28, and I haven't upgraded my plugins, through some like NoScript do autoupdate a lot. Any idea what may be responsible? Should I start testing plugins one by one? --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 14:35, 7 July 2014 (UTC)
 * Works for me with Windows 7 and Firefox 30. GoingBatty (talk) 17:36, 7 July 2014 (UTC)
 * Not working for me now: Win 7, FF32.--ukexpat (talk) 03:19, 7 September 2014 (UTC)
 * What does "not working" mean? Maybe try with your /common.js and /vector.js blanked... If it then works, you know that the problem is somewhere in that code. Any error message in the error console of FF? It works for me on FF32, OS X 10.7.5, monobook. Lupo 12:33, 7 September 2014 (UTC)
 * There seems to be a compatibility issue with delsort.js (or maybe the importScript functionality). That's the only thing I have in my common.js, and as long as that's the case, HotCat will behave as if it just wasn't there (FF 43.0 on XP). --Latebird (talk) 14:54, 22 December 2014 (UTC)
 * Your User:Latebird/common.js is broken. importScript is asynchronous, so the call to defineLink in the second line runs before the script is loaded and that function exists. If there are errors in your /common.js, gadgets may not work. Lupo 17:57, 23 December 2014 (UTC)
 * In that case the instructions on User:Fox Wilson/delsort would be incorrect. Does MediaWiki really stop loading gadgets after anything went wrong in common.js? --Latebird (talk) 12:26, 24 December 2014 (UTC)
 * Yes, those instructions are wrong. That won't work reliably.
 * It's not that the gadget wasn't loaded, but it's not started. Gadgets that want to support configuration in the user module (that is, in a user's common.js or skin.js; like HotCat) start only once the user module is loaded. Unfortunately, if the user module has errors and raises an exception (in your case, I'd expect an entry in the error log about "defineLink not defined" or some such), the resource loader never considers the module loaded and thus the gadget never starts. Lupo 12:17, 25 December 2014 (UTC)

Disable HotCat in Draft namespace?
Since article categories do not belong on pages in the Draft namespace (see Drafts & WP:DRAFTNOCAT), should HotCat be disabled in the Draft namespace? Thanks! GoingBatty (talk) 18:41, 29 January 2015 (UTC)
 * That could be configured in /local_defaults. Just return true for namespaceNumber 118 (and 119, if Draft talk shall also be excluded) in the HotCat.disable function override. Lupo 20:38, 29 January 2015 (UTC)
 * I went from HotCat to the documentation page on Wikimedia Commons to several other places before ending up at MediaWiki:Gadget-HotCat.js/local_defaults, but I still don't see how to make the change you are suggesting. Could you please be more specific?  Thanks!  GoingBatty (talk) 00:47, 30 January 2015 (UTC)
 * Replace


 * by


 * in MediaWiki:Gadget-HotCat.js/local_defaults. (Warning: above code untested.) That should do it. Lupo 06:46, 30 January 2015 (UTC)
 * Thanks - edit request made at MediaWiki talk:Gadget-HotCat.js/local defaults. GoingBatty (talk) 15:42, 31 January 2015 (UTC)


 * I strongly oppose this request as it makes it harder for established editors to remove improperly placed categories on those pages. —  16:05, 31 January 2015 (UTC)
 * Why's that? I never use HotCat - when removing a cat from most pages, I just edit the last section, mark the cat links, and press . No problem. In the case of drafts, I might insert a colon instead of deleting the cat, just as I would on a miscategorised user page, but in either case, it's not a task that requires the use of HotCat. -- Red rose64 (talk) 16:19, 31 January 2015 (UTC)
 * You don't, but I find it easier to use hotcat to remove categories. I can tap-tap and done...  I don't have to wait for the edit page to load on my mobile browser.  Just a couple taps instead of edit, scroll down, find the categories I want to remove, remove them and hope I didn't mess up anything else in that tiny 1"x2" edit window I get on my mobile, click save. I'd be happy to help make it opt-in for use of hotcat in those namespaces if requested.  I'm all for making it work better for everyone. —   17:18, 31 January 2015 (UTC)
 * I made this request after seeing an edit using HotCat to change the categories on a draft page. After reading Technical 13's first comment, I looked at the pages in Category:AfC submissions with categories before letting BattyBot change them to category links, and noticed that none of the pages had the categories added by HotCat.  I agree with Redrose64 that changing them to category links is more beneficial for the editor than removing them completely.  GoingBatty (talk) 17:37, 31 January 2015 (UTC)
 * I'd be willing to make the adjustments so that hotcat can add the prefixing  to make them links (I still prefer to remove them, and that is my personal preference as I've found often enough they shouldn't be in those categories to begin with), but I still oppose taking this tool away from editors and draft reviewers.  I do agree the first step should be a modification that takes hotcat away from editors in those namespaces that aren't at least autoconfirmed.  I don't care if this is done in the script itself or in the gadget definition, but will need to know how the community would like to handle it before I suggest possible code to do it that way.  I'll also note that the above code does not prevent IPs from using it. —   18:04, 31 January 2015 (UTC)
 * wgUserName is null for non-logged-in editors, so yes, the above code prevents non-logged-in users from using HotCat in normal operation. Lupo 22:53, 31 January 2015 (UTC)
 * BEANS, it can be overridden without much work at all. Anyways, which way does everyone want to go to permit established users to still be able to use this to remove or change existing categories on these pages? —  23:17, 31 January 2015 (UTC)
 * Re: beans... which is why I wrote "in normal operation". You can't prevent everything. But it's a bit of a moot point, since the gadget is not default-enabled. Lupo 23:56, 31 January 2015 (UTC)
 * I don't think that removal of cats should be restricted. Is it possible to code HotCat in such a way that adding or amending a cat is namespace-restricted, but simple removal may be done in all namespaces? -- Red rose64 (talk) 23:39, 31 January 2015 (UTC)

Removing categories?
Useful tool. The instructions seem to say it will remove categories with one click on the minus sign, but when I try to remove a category, it opens the edit page. Is there something I am doing wrong, or is this how it works? I am trying to change about a 1000 or more articles to be correctly placed in a single subcategory to replace two categories, and it would be much faster to not open the edit window. Windows 7 and Chrome or Firefox, and iPad with Safari. Thank you for the help. MicroPaLeo (talk) 20:39, 11 February 2015 (UTC)

Can specific suggestions on specific pages be excluded?
It appears that every couple of years, someone will add Category:Ethnic German people to Category:Swiss-German people because of a HotCat suggestion. However, this specific HotCat suggestion on this specific page is wrong (see e.g. Germans and sources quoted there such as Ethinc groups of Europe – though of course the burden of proof is really the other way round). In fact, many Swiss-Germans would very strongly oppose such a categorization. To us, it might feel as inadequate as a categorization of all English-speaking U.S. citizens as ethnic English just because they speak English.

Of course, this is only a minor annoyance. I can easily undo it by hand. But seeing as this issue seems to recur, I wonder whether it can be prevented. --mach 🙈🙉🙊 19:19, 20 April 2015 (UTC)

Suggestions not (always) working
For me, when I try to add a category using HotCat, as often as not when I type stuff in, it doesn't display any suggestions (just a blank pop-up window), even though I know there are categories that it should be suggesting (i.e. categories that exist).

cult of personality blp?
Maybe there's some logical reason for this, but it seems very odd to me that when categorizing a blp by typing in "living people" HotCat suggests "Living Colour albums" instead, every single time. Given that there are what.. hundreds of thousands of blp articles and less than a dozen Living Colour albums this just seems very weird to me, but I also know absolutely nothing about the underlying code used to generate suggestions. Beeblebrox (talk) 00:42, 24 October 2015 (UTC)
 * Beeblebrox, HotCat always produces what is first alphabetically or numerically when you start entering something. For example that's why 1961 essays and 1961 disasters come up as I start typing 1961 establishments and 1961 disestablishments....William, is the complaint department really on the roof? 23:21, 25 October 2015 (UTC)

Question
I don't know if there's a bug in HotCat or if something's malfunctioning at the server level, but I'm finding HotCat to be inconsistently reliable lately — it seems sometimes to fail to actually register an edit. Just as an example, I just tried to add the article The State of Marriage to, and had to repeat the edit three times before the article actually got added to the category. Bearcat (talk) 20:21, 2 July 2015 (UTC)
 * This is happening again. It's quite bad now - frequently I have to try four or five times to add a category to an article before it happens. -- Ser Amantio di Nicolao Che dicono a Signa?Lo dicono a Signa. 17:51, 15 November 2015 (UTC)

Request change in behavior...
Not sure if this can be done, but I'd like to see a change in behavior. I'm going through and changing a large number of pages from "Organizations established in 1972" to "Student organizations established in 1972" (and for other dates) So I need to change the 'O' at the beginning to 'Student o'. So the logical way to do that is to put my cursor after the O, hit backspace and start typing. The *problem* is that when I delete the O at the beginning of the string, it immediately capitalizes the 'R' and moves the cursor to the end of the string. What I have to do instead it move to the start of the String, start Typing "Student o" and then hit delete. Can we change the behavior so we don't have the instant capitalization and jump to the end?Naraht (talk) 15:00, 9 May 2016 (UTC)

Requested improvement: catimprove
When an editor adds a category to an article tagged as uncategorised, that tag gets removed. Please can Hotcat replace it by catimprove, in cases where the added categories are only any of the types:
 * Category:Living people
 * Cagegory:nnnn births or deaths
 * Category:Alumni of xyz college.

None of these categories provide adequate categorisation for a person, alive or dead, and anyone who has a Wikipedia article should always come within some category associated with their occupation or other source of supposed notability. Hotcat is helping editors to edit unhelpfully here, by removing the "uncategorised" but not, at present, adding "catimprove", so that the article will no longer come to the attention of editors eager to add categories which are lacking. Can it please be improved? as an editor with whom I've recently discussed this. Pam D  17:58, 23 July 2016 (UTC)

HotCat enabled by default
I increasingly feel HotCat should be enabled by default on new accounts to encourage discovery. Having autocomplete makes it by far the most intuitive way to add categories, something that most new accounts have no clue about - certainly I didn't when I joined. It would be nice if there was something like it for WikiProjects, too. Blythwood (talk) 13:02, 25 September 2016 (UTC)


 * I too think that HotCat should be enabled by default...for all Wikipedia users. Do you have an idea who to contact to get this done? Otherwise I'll request this at Village pump (proposals). I hope you're okay with me moving your unrelated comment into a new section.
 * Also there is something like it for WikiProjects as well: User:Kephir/gadgets/rater. Actually most of my work on Wikipedia wouldn't be possible (or at least a hell lot slower) without these 2 tools. My hope is that both get built into Wikipedia as preferences that are enabled by default.
 * --Fixuture (talk) 17:46, 29 September 2016 (UTC)

Adding a category to multiple pages
Is it possible to use HotCat to add a category to a all the pages in a list? For example I got these files: And I want to add the category commons:Category:Wrist clasps in the Portable Antiquities Scheme to all of them. Is it possible to do that with HotCat (without manually adding it to each item, of course) or I have to use AWB with a robot account? Fructibus (talk) 18:27, 5 October 2017 (UTC)

Subcategories
Is it possible to have HotCat warn when the category being added is a parent category of a category already assigned to the article? For example, the article is already part of Category:Japanese people stubs and the user wishes to add Category:Japanese people. Will HotCat suggest "Japanese people" in that context? --Big_iron (talk) 19:41, 11 December 2017 (UTC)
 * While it's usually wrong to add a parent category, in this example it's right, as the article will be removed from the stub category when it ceases to be a stub. Pam  D  23:15, 11 December 2017 (UTC)

 * Accoridng to MediaWiki:Gadget-HotCat.js, the script is maintained on Commons, so that's where the troubleshooting needs to take place. <span style="border-bottom:2px dotted #0f8; font-family:Seravek, serif;">Senator2029 “Talk” 06:33, 4 June 2018 (UTC)
 * I’m having the same issue. It happens when removing categories or doing multiple things at once but not when simply adding categories. Inter qwark talk  contribs 3:13 am, Today (UTC+2)

Categorization and stub templates
As per WP:SECTIONORDER, categories are supposed to go above stub templates, but HotCat automatically adds categories below stub templates. Is there a way the program can be rewritten to automatically place categories above stub templates, either when adding a single category or multiple cats at a time?

Edit summary when removing sort key
If you remove a sort key, for example  from , it gives the following edit summary:. But wouldn't a summary like  or something similar be much better? 88.113.105.159 (talk) 18:54, 19 March 2019 (UTC)
