Suggestions for extensions to be integrated

An extension should be bundled with the installer after it has become extremely widely used. There are various schools of thought concerning other extensions. When deciding whether to integrate an extension into the core, one should consider the likelihood, if any, that extensions will be written that depend upon that functionality, and the prospects that it might be later desired to remove that functionality from the core, which would break those extensions. Extensions with uncommon external dependencies should generally not be bundled with the installer or integrated into the core.

While this page can be used for suggestions and discussion, actual work on bundling extensions in the installer happens on Phabricator, in and subtasks. For creating new tasks see /Checklist.

AbuseFilter

 * This is an immensely helpful tool for preventing spam-edits and should be available to everyone creating a new wiki. It needs Extension:AntiSpoof.--Baumgeist (talk) 17:49, 29 May 2013 (UTC)
 * Any more opinions? --Nemo 07:07, 10 September 2013 (UTC)
 * MacFan4000 (talk) 23:19, 24 July 2017 (UTC)
 * seems helpful to include by default. --TheSandDoctor (talk) 15:54, 27 January 2020 (UTC)
 * . Reh  man  06:15, 9 August 2020 (UTC)

AntiSpoof

 * AntiSpoof has no default rules installed and isn't an obvious thing to find, so is of limited use to just install by default. --brion 21:17, 8 June 2011 (UTC)
 * It is a prerequisite for Extension:AbuseFilter though. --Damian Yerrick (talk) 19:57, 5 December 2012 (UTC)
 * . Reh  man  06:14, 9 August 2020 (UTC)

Chameleon

 * Chameleon skin is a twitter boostrap based skin that can very easily be configured. Many third-party MW installations use it. Often mobile/desktop versions are not wanted, but a responsive design. Chameleon has a responsive design based on the popular Twitter bootstrap and is actively maintained. --Krabina (talk) 08:41, 14 September 2021 (UTC)
 * It is one of the most popular skins --Jeroen De Dauw (talk) 10:55, 14 September 2021 (UTC)
 * Agree. Would use this. - Lbillett (talk) 13:50, 14 September 2021 (UTC)
 * --&#91;&#91;kgh&#93;&#93; (talk) 20:41, 14 September 2021 (UTC)
 * : The most powerful and flexible skin out there. -- Cavila 18:44, 16 September 2021 (UTC)
 * we use this skin essentially in all our wikis. Emwiemaikel (talk) 14:50, 18 September 2021 (UTC)
 * Its not written down anywhere I can find, but I'm pretty sure bundled extensions all need to be hosted on gerrit, and this is hosted on github - as long as its on github --DannyS712 (talk) 17:16, 19 September 2021 (UTC)

CheckUser

 * should not. There are laws in some countries forbidding logging of IPs, etc. — Preceding subst:unsigned comment added by VasilievVV (talk • contribs) 21:49, 2 August 2008‎ (UTC)
 * So it should be disabled by default. Soxred93 00:35, 26 January 2009 (UTC)
 * COPPA forbids collecting e-mail addresses in some circumstances that we don't accommodate (sites targeted at minors must ask for age and get parental approval if age < 13). And we don't provide any way at all for admins to comply with that.  Since when does the law of one country force us to not add a feature for everyone else?
 * What country actually forbids collecting IP addresses from being logged period? Some may require them to be discarded after a period, but CheckUser does that.
 * We already log IPs in rc anyway.
 * So this is an entirely unreasonable reason. All bulletin boards I know of, for instance, have similar functionality enabled by default, and they don't even typically allow you to purge old IPs. —Simetrical (talk • contribs) 12:41, 26 January 2009 (UTC)
 * I agree with Simetrical. It's an out of the box feature available to staff on most comparable software, if anything MW's implementation is extremely conservative and has a lot more oversight. Missing this after coming from forums and other places is kind of jaring. --etesp (talk) 20:57, 13 July 2014 (UTC)
 * MacFan4000 (talk) 23:19, 24 July 2017 (UTC)
 * See also T37653 (closed in 2012, but no major discussion) and Topic:Rgnwdto1i79otf9t (brief discussion in 2013). Quiddity (WMF) (talk) 21:20, 17 July 2019 (UTC)
 * Support bundling, per above. Reh  man  06:10, 9 August 2020 (UTC)

Disambiguator

 * Ship in tarball, not merge, when Special:Disambiguations is removed from core. --Moejoe000 (talk) 10:58, 14 January 2013 (UTC)
 * Core is better. --Nemo 12:13, 14 January 2013 (UTC)
 * I originally implemented it in core, but was told it should be built as an extension instead. Personally, I thought it would make more sense in core, but I was under the impression that consensus was otherwise, per https://bugzilla.wikimedia.org/show_bug.cgi?id=35981. Let's discuss further in the bug. Kaldari (talk) 23:20, 15 January 2013 (UTC)
 * I also think it makes more sense in core. Btw, some discussion has occurred on wikitech-l. --Waldir (talk) 15:52, 6 February 2013 (UTC)
 * Moved to "bundle" section because the functionality was removed from core and this will obviously not be reverted any time soon. --Nemo 07:07, 10 September 2013 (UTC)

DynamicPageList

 * [disablable] — a.k.a. DynamicPageList. — Preceding subst:unsigned comment added by VasilievVV (talk • contribs) 21:49, 2 August 2008‎ (UTC)
 * A nice feature for sure, but may not be something that would be useful as a bundled extension. Probably useful for mid-to-larger wikis. Reh  man  06:04, 9 August 2020 (UTC)

DynamicSidebar
Quite a useful feature to be bundled. Reh man  10:09, 9 August 2020 (UTC)

Echo

 * I think it would be ideal to include this extension to notify visitors and users alike of (temporary) important things.
 * Although this is probobly worth integrating into core. MacFan4000 (talk) 23:19, 24 July 2017 (UTC)
 * This is definitely an essential extension for every online mediawiki, community system without fast notice will be bad. --LazyKnight (talk) 18:33, 22 December 2017 (UTC)
 * I strongly agree this is greatly needed. -- Examknow ( Lets Chat ) 23:08, 4 March 2019 (UTC)
 * this should definitely be integrated. --TheSandDoctor (talk) 15:55, 27 January 2020 (UTC)
 * . Reh  man  05:31, 9 August 2020 (UTC)
 * --Krabina (talk) 08:56, 14 September 2021 (UTC)

FlaggedRevs

 * With more and more gaming wiki's out there, I think this could be ideal for user pages, (for instance character pages) where someone else than the owner of the character might suggest a revision and the owner uses it or rejects it. For more CMS oriented wiki's this could also be very useful.

ApprovedRevs

 * I would suggest ApprovedRevs as an alternative. It is much simpler to set up and use.

HitCounters
The Hit counters feature, removed from core. Requires the extension to be created first, see T74420. --Nemo 21:15, 14 January 2015 (UTC) P.s.: The change is 221059. On the RfC, report and ML, I count 12 persons who wish to keep the feature and nobody but the 2 proposers who want to actively remove it.
 * Agreed. We should integrate it. -- ☠ MarkAHershberger ☢ (talk) ☣ 18:58, 17 November 2016 (UTC)
 * +1 Baxi69 (talk) 19:01, 17 November 2016 (UTC)
 * +1 --Subfader (talk) 19:21, 17 November 2016 (UTC)
 * Other interesting data: the extension is installed on standalone wikis out of a total of  wikis using 1.25+, i.e. 3 %. This percentage, projected to all the standalone wikis, would make this extension the 41st most popular. Considering the extension is very new and rather hard to install and that some wikis are probably stuck on 1.24 because of  the lack of this feature in the tarball, this may easily be the most popular extension recently created. Nemo 19:55, 17 November 2016 (UTC)
 * Highly speculative. --2003:72:6D24:DB00:B57A:5017:F0BC:133A 16:21, 4 June 2017 (UTC)


 * For larger wikis, this may not be helpful. However, this is very useful for smaller wikis who don't necessarily have caching, or more detailed analytics running. -- Prod (talk) 20:51, 18 November 2016 (UTC)
 * +2 Every public wiki and nearly every private wiki I "control" wants to keep this feature. For a lot of them this was not even debatable. So great to have this extension and even better to have it integrated. --&#91;&#91;kgh&#93;&#93; (talk) 20:01, 19 November 2016 (UTC)
 * +1 Platonides (talk) 19:34, 21 November 2016 (UTC)
 * -2 In the meantime several MediaWiki versions, also LTS versions, have been released without this extension. The extension is hard to install, which if you ask me, makes it basically useless. In 1.28+ it cannot be installed at all. If installed after months or years without it, the numbers will all be incorrect anyway. Also there are way better solutions for visitor tracking so there is no need to further bloat the Core with this poor man's counter. If you really want to count page hits, a third party tool like Google Analytics or Piwik is way more useful. --2003:72:6D24:DB00:B57A:5017:F0BC:133A 16:18, 4 June 2017 (UTC)
 * +1. Bennylin (talk) 22:40, 20 November 2017 (UTC)

MassMessage
Wikimedia uses it and it is very useful to me. 67.244.49.134 20:07, 18 December 2016 (UTC)
 * I don't think that MM is that widely useful to be included in the tarball. Plus it requires a fully functioning job queue to be useful. Legoktm (talk) 01:52, 19 December 2016 (UTC)
 * Many installs use it. MacFan4000 (talk) 23:19, 24 July 2017 (UTC)
 * . Reh  man  06:16, 9 August 2020 (UTC)

MathJax
Mediawiki is very good instrument to arrange the mathematical results. Consider to include some MathJax; it seems to be best among various supports of the formula typing. Domitori (talk) 14:53, 6 April 2013 (UTC)

MobileFrontend
This will provide a Mediawiki frontend to mobile devices. The current frontend seems much too complicated to use there. --Kebap (talk) 12:58, 2 August 2013 (UTC)
 * YIKES! i've made a bootstrap skin for funtoo.org that takes nothing more than the skin, no extra extensions, works on phone tablet, and pc.  bootstrap skin requires no separate m.subdomain.com addresses.  all unified =)  | funtoo skin screen shots  it's designed to be very straight forward and very maintainable.


 * MacFan4000 (talk) 23:19, 24 July 2017 (UTC)

Newest Pages
Very simple extension found on some wiki now. Not a critical feature perhaps, but it would make sense for this to be an option alongside $wgRCMaxAge and friends, with sane defaults. On a wiki with few dozens pages, showing new pages of the last 30 pages only doesn't make sense. On the other hand, someone may argue we should just raise the defaults for $wgRCMaxAge. --Nemo 08:41, 30 December 2014 (UTC)

NewUserMessage

 * Should be included in core : it helps to create a basic community by giving indications about the wiki and is very simple to configure. Already used in wikimedias wikis. --Jibec (talk) 20:05, 26 November 2012 (UTC)
 * The Welcome Notification in Extension:Echo accomplishes a similar function. I would hold off on merging this with core until we have a clearer picture of what we're going to be doing for new users via Echo and Flow. Kaldari (talk) 23:43, 15 January 2013 (UTC)
 * Do not merge (maybe to be bundled): this extension does a very particular thing. It may be interesting for public wikiks, but there are a lot of different approaches to achive effects (extension Echo as Kaldari mentioned, personal welcomes, using a bot, just use a welcome message after account creation,...). --Moejoe000 (talk) 10:03, 16 January 2013 (UTC)
 * Neutral on this, I'm unsure though I like the extension and I think future possible broader solutions must not block improvements possible in the present. Moved to bundle section. --Nemo 07:07, 10 September 2013 (UTC)
 * Neutral on bundling, but disagree with merging to core. Reh  man  05:35, 9 August 2020 (UTC)

Popups
This feature would be useful in many use cases. Reh man  10:09, 9 August 2020 (UTC)
 * since both extensions it is dependend on are already bundled, this is an obvious step --Krabina (talk) 08:54, 14 September 2021 (UTC)

StructuredDiscussions
Simpler discussion threads like StructuredDiscussions is a major feature for wikis. If this cannot be integrated in core, it should at least come as an easy-to-install option in the bundle. Reh man  10:09, 9 August 2020 (UTC)
 * Oppose - unmaintained, so many problems and bugs, not easy to revert, not a benefit to enable imo --DannyS712 (talk) 07:12, 11 December 2020 (UTC)

TemplateSandbox
Can see how a template will really show up. Should be useful for lots of wikis. -- Prod (talk) 17:23, 20 April 2013 (UTC)
 * MacFan4000 (talk) 23:19, 24 July 2017 (UTC)
 * Neutral. I believe most non-Wikimedia wikis may not find this that useful. Hence bundling with the installed may not be a good idea. Reh  man  05:48, 9 August 2020 (UTC)

Thanks
Used by WMF. Very easy to use. 2002:43F4:3186:1234:716B:2BF2:8A30:F8DC 22:07, 29 January 2017 (UTC)
 * Probobly worth integrating into core. MacFan4000 (talk) 23:19, 24 July 2017 (UTC)
 * Probably worth integrating indeed. --TheSandDoctor (talk) 15:57, 27 January 2020 (UTC)
 * . Reh  man  05:35, 9 August 2020 (UTC)
 * --Krabina (talk) 08:55, 14 September 2021 (UTC)

Validator

 * Validator is a generic parameter handling tool. As a lot of parameter handling is happening in both core and extensions, it would greatly increase simplicity and consistency, as well as add a lot of useful things such as auto documentation generation. I'm quite sure most core devs will go "we don't need this". Try it, and then tell me it's not vastly better then hard-coding all the stuff over and over again for every use-case. --Jeroen De Dauw 03:29, 8 January 2011 (UTC)
 * Since this is not currently used by core or production stuff, no reason to ship it just yet. To the extent that things in it are useful for other extensions, those things probably belong in core; doesn't make sense as its own extension. --brion 21:17, 8 June 2011 (UTC)
 * Such a meta extension should only be included by default when and if it has wide usage in my opinion. Bawolff (talk) 17:46, 26 November 2012 (UTC)
 * It's now the 18th most popular extension according to WikiApiary (excluding farm wikis), if that helps with the decision. --etesp (talk) 20:57, 13 July 2014 (UTC)
 * --Krabina (talk) 08:53, 14 September 2021 (UTC)

Variables

 * I've found this handy for making complex templates more efficient and readable. It's a fairly straightforward and popular extension which could benefit many wikis. --etesp (talk) 20:57, 13 July 2014 (UTC)
 * This one isn't compatible with the direction the parsing of pages is headed in, since literally its entire functionality relies on creating and using global page state. In addition, it's largely superseded by Scribunto/Lua - if you need to use this extension to implement some template, chances are good you'll have a much cleaner and lighter end result by implementing the functionality in a module instead. 「 ディノ 奴 千？！」? · ☎ Dinoguy1000 12:02, 9 April 2018 (UTC)
 * Disagree with bundling, as it would most probably not be enabled for same reasons WMF did not enable. Alternatives to this function exist. Reh  man  05:50, 9 August 2020 (UTC)
 * . Without this extension my wiki would not be able to function. And no, Scribunto/Lua isn't a replacement, even if my host allowed me to install it (which it doesn't). Cavila 18:46, 16 September 2021 (UTC)

WikiLove
Used by WMF. Very easy to use. 2002:43F4:3186:1234:716B:2BF2:8A30:F8DC 22:07, 29 January 2017 (UTC)

LoginNotify
A useful extension which notifies you when someone logs into your account. Enabled by WMF wikis. Reh man  10:09, 9 August 2020 (UTC)

NoTitle

 * how about putting Extension:NoTitle somewhere on here? Wikademia (copied from discussion page--Moejoe000 21:06, 18 May 2011 (UTC))
 * Moved here. Is a very trival feature. Wikipedia uses a JaveScript workaround (for main pages). Removing just the Title in HTML seems really better. --Moejoe000 07:07, 10 June 2011 (UTC)
 * The way this extension does it isn't much cleaner, it inserts a tag in the head section for scripts to declare   on the first heading. On the other hand, removing it may break bad scripts. Krinkle 15:39, 13 June 2011 (UTC)
 * I was suggesting to add the feature, not the particular implementation of the extension--Moejoe000 06:54, 14 June 2011 (UTC)

TitleKey

 * Might want to merge this straight into the page table (as long as we get that easy schema upgrade ability on Wikimedia first...). — Preceding subst:unsigned comment added by VasilievVV (talk • contribs) 21:49, 2 August 2008‎ (UTC)
 * Integrating TitleKey would be beneficial to new mediawiki users. Its use case is confusing, because so much seems to work already without it, making it hard to see whether it is a legacy extension or not. What I mean: this adds substantially to the "learning curve" of installing a usable mediawiki installation. The main reason to not include it in core seems to be that it is a little bit of a hack for something (case-insensitive search and suggestions) that should work without the need to install another extension and a special table - correct? Can this then be fixed? G.Hagedorn 08:53, 30 October 2011 (UTC)

WikiEditor (already bundled)
WikiEditor is already bundled, but would make more sense if it is part of the core (and doesn't require separate installation). Reh man  10:09, 9 August 2020 (UTC)

 * CharInsert is going to be pretty much obsoleted by the new edit toolbar, which has a much cleaner system for special chars / edittools. --brion 19:42, 19 August 2009 (UTC)
 * I'm pretty sure the implementation of this could be improved dramatically. —Simetrical (talk • contribs) 12:42, 26 January 2009 (UTC)
 * Perfect is the ememy of good? Even though it has been adopted widely, it not being perfect would prevent it from being added to core, even though no one touched it since June 2006? (14584)? siebrand 15:16, 26 January 2009 (UTC)
 * Yeah, sure. It could be cleaned up in core as well as anywhere.  Just saying. —Simetrical (talk • contribs) 02:02, 27 January 2009 (UTC)
 * This extension should be obsoleted by WikiEditor. And anyway: the current version of this extension could be re-written completely in JavaScript (with the effect that users that do not have JavaScript enabled do not see unusable links) --Moejoe000 18:01, 8 May 2011 (UTC)

I'd much rather see us work out a proper configuration database which can have a clean, safe UI written on top of it; supporting multiple wikis with cascading configuration options from global -> group -> individual site is a must. --brion 19:40, 19 August 2009 (UTC)

 * I wouldn't bother with this by default necessarily, though some people like it. The tree widget is rarely used directly, so it's not needed for content compatibility. --brion 21:17, 8 June 2011 (UTC)
 * It's pretty useful. E.g., compare how easy it is to browse documents in this Category listing compared to this CategoryTree listing. The latter is much more navigable, because you can see the full filenames. I also think CategoryTree has reached a degree of popularity sufficient to justify its inclusion in the core; the wikisphere seems to have settled on it as a standard.

Gadgets

 * Gadgets are super-useful, but it's still a bit awkward to actually share gadgets from site to site. Might not hurt to slip it in for 1.18, but it'll be way more useful in future versions. --brion 21:20, 8 June 2011 (UTC)
 * Sorry, I have to oppose here: (the current implementation of) this extension does not provide anything by default - one has to modify system texts to install gadgets. Persons who know how to do that, can also install the extension manually. If also configuration of Gadgets is easy, I would also suggest to bundle. --Moejoe000 09:46, 30 October 2011 (UTC)

Interwiki

 * (at least the option to view available interwikis, see also InterwikiList) - merged in, reverted in - "please continue working on it, it'd be a nice thing to have for third-party installations if the UI is cleaned up." (ref)
 * It has since been cleaned up quite a lot. I think it should be added to MW core. SPQRobin 20:38, 11 June 2011 (UTC)
 * I agree, it's a simple extension to view and modify interwikis without having to mess in the database and also keeps track of everything in a logging table. Since the interwiki table is populated by default it makes sense to have this in core. Krinkle 12:44, 4 July 2011 (UTC)
 * Still doesn't work for WMF wikis -- any implementation of this needs to work with $wgInterwikiCache. ^demon 17:16, 7 July 2011 (UTC)
 * Also, a lot of the complaints I see from the previous merge still exist in the extension: those need resolving. ^demon 17:18, 7 July 2011 (UTC)
 * I made it work with the interwiki cache, and cleaned up the code. Editing the data is disabled when the cache is used. Are there any other issues left? SPQRobin 16:18, 20 July 2011 (UTC)

LocalisationUpdate
It's about time we start supporting localisation well in all MediaWiki installations. As far as I know, LU has already been updated to use will soon work (thanks to 34496, while WMF used a custom hack) with gerrit/git reliably enough; the problem would be that as is it needs cron (like which was discarded). If we had this, we could also use some special system messages, or qqq messages, to spread crucial information or docs (see also 41578). --Nemo 21:28, 10 November 2012 (UTC) ✅ MediaWiki 1.21, 65649
 * I'm somewhat doubtful this is really needed for proper localization support. We ship the localizations with MediaWiki. Well it is certainly nice for WMF wikis to have up to the minute localization updates, I don't see why it is critical for up to the moment updates of the localizations in general. Bawolff (talk)
 * Have you considered that most wikis are not updated for months or years and that sometimes not even 1.x.y releases include localisation updates? WMF wikis are those which need LU less now, thanks to the bi-weekly update. Could you please elaborate on why updated localisation is not so useful in your opinion? I don't know where to start replying. Thanks, Nemo 17:55, 26 November 2012 (UTC)
 * I don't see the need for bundling LocalisationUpdate. I think it would be much better to find a way to encourage updating the whole MediaWiki installation of outdated wikis rather than focusing on updating their localisations. If we offer LocalisationUpdate *from now on*, that won't have any effect for wikis that are already using older versions at this moment anyway. And non-WMF wikis are usually in major languages that are already very well localised. SPQRobin (talk) 19:31, 8 January 2013 (UTC)
 * Do you have any stat for the last claim? About updating, by default security updates don't necessarily include localisation updates. Updating MediaWiki is not a solution to have an up to date localisation, unless one uses git of course. We should go towards a usable experience for tarball users. Nemo 19:44, 8 January 2013 (UTC)
 * No, I don't, but it's quite logical (see also sites using MediaWiki). Or, the other way around, look at translatewiki:Translating:MediaWiki/statistics/1.20: I don't think there are many non-WMF wikis at all in languages with less than 80-90% localised. About updating, I'm not really talking about security updates, I'm also talking about wikis using versions like 1.15, 1.16 etc, I think it would be better to focus on wikis upgrading more regularly rather than solely keeping their localisations up to date. SPQRobin (talk) 18:55, 14 January 2013 (UTC)
 * You should use this list and extract language info from there, not rely on assumptions. "Why don't you focus on X instead" is not a valid argument, anyway it's also wrong here because in these days I am working on contacting those thousands of wikis which need to upgrade.
 * I'd rather like to hear reasons why bundling LU would do harm or not do good. --Nemo 20:01, 14 January 2013 (UTC)
 * I just give my opinion, I said "I think it would be better to focus on...". And please, even from the linked list it is, imho, quite obvious that when you take away all English, German, Italian, Spanish, ... wikis you will have only few wikis left in "rare" languages. SPQRobin (talk) 00:14, 16 January 2013 (UTC)
 * Why don't security updates include localization updates? I think they should. The fact that many wikis don't update actually makes me like the idea of including this extension a bit more. A separate conversation from if we want to bundle this is how we would make it work. It needs cron, and I'm opposed to bundling any extension that cannot be automatically set up via the web installer. Bawolff (talk) 23:15, 17 January 2013 (UTC)
 * Can you file a bug with a proposal on how to make the installer set such things up? It was needed for TorBlock too. In the case of LU, running the script once in a while is still a valid use case. Security releases usually include localisation updates, but it depends on Siebrand being notified in advance and having enough time for it the days before. --Nemo 09:05, 18 January 2013 (UTC)
