 Not done: this is not the right page to request additional user rights. You may reopen this request with the specific changes to be made and someone will add them for you, or if you have an account, you can wait until you are autoconfirmed and edit the page yourself.

Displaying Category Sortkeys in Category?[edit]

Is there a way while viewing a category to see the sortkeys which caused the ordering in a category? (and adding a tool as the solution would be fine)Naraht (talk) 15:58, 25 February 2019 (UTC)

@Naraht: I only know the API method we told you about at Wikipedia:Help desk/Archives/2019 February 26#Seeing the sortkeys in a category? I have made a script to use it: User:PrimeHunter/Sortkeys.js. Install with this in your common JavaScript:
importScript('User:PrimeHunter/Sortkeys.js'); // Linkback: [[User:PrimeHunter/Sortkeys.js]]

PrimeHunter Thank You. On what pages will it show up and do I need to activate it by clicking something in the Tools?Naraht (talk) 11:01, 3 May 2019 (UTC)
@Naraht: The link will show up on all category pages in the desktop version of the site, assuming your browser has JavaScript enabled. You have to click the link to see the API page with the sortkeys. It gives Sort keys on Category:2019 so it's not pretty for humans. It ignores which part of the category you were looking at.

PrimeHunter I have Javascript turned on (other tools work including one that stops all redirects from going forward), but where will I see the link? Over on tools? Please take a look at my current common.js to make sure that I am using it right...Naraht (talk) 11:17, 3 May 2019 (UTC)
PrimeHunter Thank you found it. Not sure why it is in the middle of my tools though.Naraht (talk) 11:34, 3 May 2019 (UTC)

Suggestion for article[edit]

Just for the sake of a faster Google search: please include the literal words "vertical bar" refering to the character | used in the explanation for [[Category:Category name|Sortkey]] (for me, it was a very useful explanation for understanding why the | in categories, but I had to deduct it from context and someone else could have difficulties in finding this information about wiki coding). I don't dare to edit this article since as you guys can see it right now, my English writing is horrible. Greetings. --Mizukane203 (talk) 15:35, 10 November 2019 (UTC)

Flattening a category[edit]

Is the operation of flattening a category possible? That is, I want to see all pages in a category, as well as its subcategories (with this definition recursively applied to included its subcategories as well, etc.). I use the word flatten analogously to "flattening a nested array" here.--2602:306:C531:7310:7C8C:339:8338:B872 (talk) 20:34, 27 December 2019 (UTC)

Yes, the Wikipedia:PetScan tool can do this. -- John of Reading (talk) 07:47, 28 December 2019 (UTC)
