Notheme

@TheDJ: Unfortunately adding notheme introduced some glitches (apart from which it looks good): in Template:Extension#Usage, the red link and the error text (invalid) are too dark red, and the brackets of the [toggle] buttons are black instead of white. Am I right in assuming that these glitches will go away if, as proposed in the edit summary, the overrides are removed at the site level? —Tacsipacsi (talk) 16:57, 1 January 2025 (UTC)

I'd have to look into it. The collapsible is actually interesting. It seems to fallback to UA styling, which has explicit color:black for buttons it seems. That might have to be fixed in core. —TheDJ (Not WMF) (talk • contribs) 09:42, 2 January 2025 (UTC)

Setting the buttons to color:var(--color-base,#202122) would be a good idea in general for consistency with other colors and across browsers; but it wouldn’t help in our case, as --color-base is overridden in .notheme to #202122 regardless of the theme. —Tacsipacsi (talk) 00:14, 3 January 2025 (UTC)

Prefix

It seems that the "Parameters" section of this template ignores the configuration prefix setting from extension.json. Alexander Mashin ^talk 04:24, 3 April 2025 (UTC)

Extension adding rights not categorized

The Extension:DeletePagesForGood page states that the extension adds rights, but it is not categorized under Category:Extensions which add rights. Shirayuki (talk) 12:07, 21 April 2025 (UTC)

Changing cat() to tcat()

What are peoples' thoughts of changing the three uses of cat() in Module:Extension (currently used for the categories 'Extensions with manual MediaWiki version', 'Extensions without MediaWiki version' & 'Extensions not in ExtensionJson') to tcat() -- does anyone have any objections? I'm hoping that something like this would make it easier to look/work through those maintenance categories, as it'd deduplicate the multiple listings that currently exist within them for a number of extensions (by moving the translated pages to categories for their languages).

Pinging @P858snake as you tried something like this previously in Special:Diff/6801741 but self-reverted the edit an hour later, & @Samwilson as it looks like you added those categories in 2021. Best, ‍—‍a smart kitten_[meow] 13:51, 9 July 2025 (UTC)

@A smart kitten: Yes, that looks like it'd be fine, I think. I can't remember why we ended up with two categorising functions. Sam Wilson 01:12, 10 July 2025 (UTC)

Boldly Done in Special:Diff/7743936. Let's hope nothing breaks :D ‍—‍a smart kitten_[meow] 18:57, 13 July 2025 (UTC)

Great! I guess the cat() function can be deleted now? Or in a while when no one's noticed anything broken. Sam Wilson 03:02, 14 July 2025 (UTC)

Maybe - given that tcat() calls cat() itself, I guess it depends on whether it's better to move cat()'s logic into tcat() or to keep it separate. ‍—‍a smart kitten_[meow] 13:44, 14 July 2025 (UTC)

False positives

This template erroneously puts some extensions that are present in the non-WMF repository into the Category:Extensions not in ExtensionJson. The reason, I presume, are the spaces in the extensions' names. Examples inlude extensions with names starting with Semantic .
