== Losing list formatting ==

This template seems to be losing the formatting of bulleted lists. See example. 

{{Transclude excerpts as random slideshow 
 | Scuba gas planning 
 | paragraphs =3
 | files =
 | fileargs =
 | more =
 | errors = 
}}

The template {{tl|Transclude lead excerpt}} seems to do it right. See example.

{{Transclude lead excerpt
 | Scuba gas planning 
 | paragraphs =3
 | files =
 | fileargs =
 | more =
 | errors = 
}}

so the module is working. Cheers, &middot; &middot; &middot; [[User:Pbsouthwood|Peter (Southwood)]] [[User talk:Pbsouthwood|<sup>(talk)</sup>]]: 12:07, 28 July 2018 (UTC)
:This is from a limitation of the gallery syntax, where the caption can't contain any new lines, so the module changes them to {{tag|br|open}} tags. It might be possible for the module to change a wikitext list into a html list with {{tag|ul}} and {{tag|li}} tags.

== Option for title display ==

Would it be possible to extract the title of the selected excerpt and display it at the top of the rendering? Some excerpts are not very obvious about their topic, and particularly with the slideshow arrangement, it would help to identify what the excerpt is about. In the case of a section, the full section title would probably be most generally useful. &middot; &middot; &middot; [[User:Pbsouthwood|Peter (Southwood)]] [[User talk:Pbsouthwood|<sup>(talk)</sup>]]: 17:11, 28 July 2018 (UTC)
:For lead excerpts at least, it sounds more like a content issue that should be addressed at the individual articles – lead sentences should be making it obvious what the topic of the article is ([[MOS:LEAD]]). If they do that properly, than showing the page title as well is superfluous. For sections, showing the article title and section makes sense, but should probably be done at [[Module:Excerpt]] rather than here. - <u>'''[[User:Evad37|Evad]]''37'''''</u>&nbsp;<span style="font-size:95%;">&#91;[[d:w:User talk:Evad37|talk]]]</span> 03:40, 29 July 2018 (UTC)
:True, but most portals created using the new structure are going to include ''some'' articles with badly formed leads, and having the title displayed may reduce confusion in the reader. It is not reasonably practicable to check every lead, and new articles will be added which will be included automatically.

== Annotated links in lists ==

{{U|Evad37}} I think I may be repaying your helpfulness by creating more work. Sorry about that. 

I have made a template {{tlx|Annotated link}} which is useful in lists to annotate the item using the short description from the linked article. This obviously changes the format and now this template does not recognise the links any more - they are now inside <code><nowiki>{{Annotated link|Article title}}</nowiki></code>, where ''article title'' represents the link. 

Can this be managed without excessive overhead? An example can be seen in [[Portal:Underwater diving]] in box Diving modes, which gets a list from [[Outline of underwater diving#Modes of underwater diving]], which now has examples of the Annotated link template. &middot; &middot; &middot; [[User:Pbsouthwood|Peter (Southwood)]] [[User talk:Pbsouthwood|<sup>(talk)</sup>]]: 08:12, 13 September 2018 (UTC)

== Read more ==

{{ping|Evad37}} We have a few slideshow items just saying "Read more... Read more...".  (Sadly, the output is being [[WP:AN#Arbitrary_break_(CSD_criterion_X3)|ridiculed]] as proof by example that all portals are "shit".)

I've tracked this down and made a couple of changes in the sandbox.  They affect makeGalleryArgs when excerpt consists of just "Read more".  Firstly, a blank lead sets readmore_start_index to 1, so <code>mw.ustring.sub(excerpt, 1, readmore_start_index-2)</code> equals sub(excerpt, 1, -1) which is the whole string, and fails to remove the "Read more".  I've changed the -2 to -1, and kept the leading space in readmore_text to compensate.  Secondly, #excerpt needs to be checked again after removing "Read more" in case it just dropped below 10.

Please can you cast your eye over the code to see that it still looks reasonable?  I've added a testcase for it [[Template:Transclude excerpts as random slideshow/testcases#Blank lead|here]].  The sandbox also includes your new constants which could be a good idea, depending where the best trade-off is between run time and content.

== Bizarre behavior ==

In [[Portal:Earth sciences]], this template is broken in a very strange way. It is supposed to select from one of the links on [[Portal:Earth sciences/Selected articles]], but always loads [[Geography of Indonesia]], even though that article is not one of the links (although it used to be). No amount of twiddling with parameters or page reloading makes any difference. I use exactly the same syntax in [[Portal:Geophysics]], and it works fine there. <span style="font-family:Comic Sans MS; color:grey;">[[User:RockMagnetist|RockMagnetist]]([[User talk:RockMagnetist|talk]])</span> 22:56, 23 May 2019 (UTC)
:{{ping|RockMagnetist}} It's actually picking [[List of volcanoes in Indonesia]], which is the last entry on the ''Selected articles'' list.  Removing that entry fixes things, though I'd prefer not to do that as it's a featured list.  The volcano list starts with an &lt;onlyinclude> section, instructing any transcluding page to hide the rest of the article.  Constructing the portal puts this wikitext onto the same page as the other selected articles, so the portal duly hides the rest of the page, including the other selected articles.  If you think that this portal stands any chance of not being killed off then I'll look into enhancing [[Module:Excerpt]] to deal with this syntax.

== Why use Module:Excerpt/portals? ==

Hey! During some recent testing after a portal page was coming up under a tracking category due to a page being edited in a weird way, I noticed that this module explicitly used a /portal version of the Excerpt module. My question is - why? After some investigating (see [[Special:Diff/1094308845|this page]] <small>(will break at some point, if it has, use [https://web.archive.org/web/20220621211538/https://en.wikipedia.org/wiki/User:Aidan9382/SafeEnvironmentTesting this])</small>), and I noticed that the module covers less edge cases, trips up easier, and is even considered "deprecated", so I'm unsure why its still in use for these templates. Is there something this sub-module covers thats critical to these templates but not found in the main module? If so, what? If a conversion to the main module is possible, that would probably be a good move. If not, then I could potentially work on sorting any issues between them. [[User:Aidan9382|Aidan9382]] <sub>([[User talk:Aidan9382|talk]])</sub> 21:19, 21 June 2022 (UTC)
:If you can make the slideshow work with [[Module:Excerpt]] then I don't see any reason not to.  As you're probably aware, the history is that [[Module:Excerpt]] was created for portals (I wrote much of the code) then extended for articles (mainly by {{u|Sophivorus}}).  The two namespaces have conflicting requirements – for example, portals strip references but articles retain them – and it proved more practical to develop their functionality separately.  If one module can do both jobs, so much the better.  I wasn't aware that [[Module:Excerpt/portals]] was "deprecated".  Is that simply because it's used in portals which some editors would like to delete, or is there something specific about the code that needs attention? [[User:Certes|Certes]] ([[User talk:Certes|talk]]) 23:11, 21 June 2022 (UTC)
::Well, I'm not particularly sure ''why'' its deprecated, but thats what it was saying within the code of [[Module:Excerpt/portals]]. I'd imagine its more akin to "out of date" than "deprecated", but I don't know. Features like stripping references are currently implemented within [[Module:Excerpt]], so a swap may be possible, however I'm not gonna guarantee anything until I've read the entire thing and what its used for. If it is possible to convert, I probably will, but if not, it's not like /portals is falling apart, so its fine.

Still if you'd rather remove the notice, by all means do it! :-) @[[User:Aidan9382|Aidan9382]] Merging /portals into the main module would require adding an extra method or two to reproduce the missing behavior, for example the slideshows.

The game begins on the day of the shootings and follows Harris and Klebold after their suicides to fictional adventures in [[Christian views on Hell|perdition]].

Ledonne had spent many years conceptualizing games, but never created one due to his lack of game design and programming knowledge. He was inspired to create a video game about Columbine by his own experience being bullied and the effect the shooting had on his life. The game represents a critique of how traditional media sensationalized the shooting (in particular the role of video games), as well as parodying video games themselves. ''Super Columbine Massacre'' was created with [[ASCII (company)|ASCII]]'s game development program [[RPG Maker 2000]] and took approximately six months to complete. Ledonne initially published the game anonymously, releasing an [[artist's statement]] about the work after his identity was revealed. ''Super Columbine Massacre'' was released for free online and attracted little attention until 2006, when widespread media coverage fueled hundreds of thousands of downloads.

If the random transclusion happens to bring in [[:Super Columbine Massacre RPG!]], it includes this:
<pre>
<gallery class="switcher-container" mode="slideshow">
...
File:Blank.png|<span class="switcher-label" style="display:none"><span class="randomSlideshow-sr-only">Image #</span></span><div style="text-align:left;">{{Columbine High School massacre}}
...
</pre>
(where # is a number from 1 to 10), which distills further to
<pre>
<gallery>File:Blank.png|{{Columbine High School massacre}}</gallery>
</pre>
which is [[Special:LintErrors/multiline-html-table-in-list|Multiline table in list]] lint error. [[Template:Transclude list item excerpts as random slideshow]] needs to recognize templates that should not be brought in, and not bring them in. —[[User:Anomalocaris|Anomalocaris]] ([[User talk:Anomalocaris|talk]]) 08:46, 19 December 2022 (UTC)
:{{ping|Anomalocaris}} Thanks for the notice. Not too long ago I was doing related work on this module (and associated modules) to try and clear a seperate linter error ([[Special:LintErrors/bogus-image-options|bogus image options]]), as well as introducing some formatting changes to help display some wikitext. Some of the discussion can be seen at [[Module talk:Excerpt#Image caption fails to display correctly|Module talk:Excerpt]] and [[Module talk:Random slideshow#bogus file option lint errors|Module talk:Random slideshow]]. These linter issues have been happening for some time, though this one is new to me, so I'll look into fixing that (or finding what causes it at least). If this is a substantial issue in the meantime, or if I'm unable to find a satisfactory solution (I doubt this is a simple fix), It's probably safe to put it in the blacklist of [[Module:Excerpt/portals#L-43|Module:Excerpt/portals]], which should fix the issue for now.

:Note that I'm fairly sure blacklisting templates is the normal approach taken in scenarios like this anyways judging from [[Module talk:Excerpt]], so for now I've just blacklisted it anyways. [[User:Aidan9382|Aidan9382]] <sub>([[User talk:Aidan9382|talk]])</sub> 09:36, 19 December 2022 (UTC)
::Yes, blacklisting the template will omit the template's expansion from the portal if that's what's wanted here. [[User:Certes|Certes]] ([[User talk:Certes|talk]]) 09:50, 19 December 2022 (UTC)

== Handling onlyincludes ==

I've come back to the goal of trying to fix all the [https://en.wikipedia.org/wiki/Special:LintErrors/bogus-image-options?namespace=100 bogus file options] errors in the portal namespace caused by this module and its family, and I've managed to cut nearly every page out. However, the situation for [[Portal:Victoria]] was a little complicated. Some of the pages listed ([[2018 Geelong Football Club season|1]], [[2019 Geelong Football Club women's season|2]]) had an {{tag|onlyinclude}} tag in them, which was causing the module to try transclude something it really can't handle. Luckily, both of the articles using the tags weren't being transcluded at all, so it was safe to remove the tags. However, what's the best approach when this isn't an option? Based off my memory I don't think theres anything that can just bypass the onlyincludes in the code, and I've never seen this kind of situation before, so I'm not sure what a more proper fix would be here. Any ideas? [[User:Aidan9382|Aidan9382]] <sub>([[User talk:Aidan9382|talk]])</sub> 19:43, 23 January 2023 (UTC)

:[[Module:Excerpt/portals#L-575]] has code to handle onlyinclude, if that helps. [[User:Certes|Certes]] ([[User talk:Certes|talk]]) 20:01, 23 January 2023 (UTC)

::Let me clarify - that exact code ''is'' my problem. The slideshow attempts to grab some text to display for the article, but instead of getting the lead, it grabs the onlyinclude section, which isn't what we want, and also leads to linter errors in this specific scenario due to how complicated the sections are. Is there a way around that from a code side of things, or do we simply just have to re-format the article to work with the situation? [[User:Aidan9382|Aidan9382]] <sub>([[User talk:Aidan9382|talk]])</sub> 20:21, 23 January 2023 (UTC)
:::I suppose we need to look at why the article uses onlyinclude.  I naively assumed that it would be for the rare occasions when we should only include the text within the tag and ignore the rest.  We need to ask "what else transcludes the article?" and "how does onlyinclude help those transclusions?"  In these examples, the answers were "nothing" and "it doesn't, so get rid of it".  In general, onlyinclude may not be the best solution to whatever problem it was trying to solve.  For example, [[Portal:The Simpsons]] was unable to transclude the lead of [[The Simpsons]], because the article had onlyinclude around the episode count so that other articles could just transclude the entire article to get an up-to-date number.  (D'oh!)  We fixed that by ripping out the inappropriate noinclude tag and using {{tlx|Template parameter value|The Simpsons|Infobox television||num_episodes}} in the transcluding pages.

::::Yeah alright, that makes sense. Thanks for the example, too. I'll keep that in mind for the future. [[User:Aidan9382|Aidan9382]] <sub>([[User talk:Aidan9382|talk]])</sub> 21:06, 23 January 2023 (UTC)

== Another rendering / invalid file options error with [[Template:Transclude list item excerpts as random slideshow]] ==

In [https://en.wikipedia.org/w/index.php?title=User:Jonesey95/sandbox&oldid=1240141507 this version of my sandbox], I have used  [[Template:Transclude list item excerpts as random slideshow]] to pull in a group of five articles. The article [[2022 Clackmannanshire Council election]] causes significant rendering errors, showing me things like <code>UNIQ--templatestyles-00000010-QINU</code> instead of an excerpt. The excerpting also causes Linter "bogus file options" errors. Can someone please look at this error? 

This is a simplified case of a problem that is happening in Portal pages, including [[Portal:Scotland/Featured]]. I can provide a screen shot if necessary. It may appear only sometimes in the Portal pages, depending on which articles are excerpted. Pinging {{U|Evad37}}, who has been helpful in the past in tracking down these edge cases. – [[User:Jonesey95|Jonesey95]] ([[User talk:Jonesey95|talk]]) 19:31, 13 August 2024 (UTC)
:Note: In a [[Module_talk:Excerpt_slideshow#Template:Transclude_list_item_excerpts_as_random_slideshow_pulls_in_unwanted_templates|discussion above]], {{U|Aidan9382}} blacklisted a template that was causing trouble. In this case, it may be a table that is causing trouble. If that is the case, can we exclude tables from the excerpts? – [[User:Jonesey95|Jonesey95]] ([[User talk:Jonesey95|talk]]) 19:37, 13 August 2024 (UTC)
::This seems to be the same issue that was had in {{slink||Handling onlyincludes}} above, where an <code><nowiki><onlyinclude></nowiki></code> tag is causing the module to target text that it isn't designed to handle (in this and the above case, a table, which don't work with the gallery format this creates). Unfortunately, I'm not sure what the best solution here is. I think in this module's context, it would make sense for it to ignore onlyincludes, since this module is generally just interested in extracting the lead.

:::I've implemented what I suggested above, which fixes the specific case you provide as well as 2 portals with a current linter error (unsure about the 3rd's issue). Bogus file options is very much a game of whack-a-mole when it comes to portals since the page selection tends to be randomised, but this should help a decent bit with avoiding the weirder cases.

::::Thank you. The randomization of excerpts can indeed make error-finding and error-fixing a little tricky. I'll keep an eye on the Linter error list. – [[User:Jonesey95|Jonesey95]] ([[User talk:Jonesey95|talk]]) 15:15, 19 August 2024 (UTC)
