Colours for dark mode

A module sets colours for table headings by using colour names such as 'white', 'black' or hex values for text, background and cell border. This is fine for normal skins but how should it be coded to say "use the inverse colour in dark mode"? Dark mode is picking up the names and using those as absolute, where I think what I want it to say is "unless colour is specified use skin defaults for text and background" (the default for border is 'none' so that's not a problem).

Isn't styling something that could be / should be done with template styles css?

—Trappist the monk (talk) 16:17, 28 October 2024 (UTC)

if i understood template styles, quite possibly. Nthep (talk) 16:29, 28 October 2024 (UTC)

This probably should have been asked on WP:VPT since it has nothing to do with modules.

mw:Recommendations for night mode compatibility on Wikimedia wikis are the official recommendations from WMF about how to deal with dark mode consideration. The relevant section is this one.

You can probably be assisted further by providing a specific template/module of interest where you are trying to be dark-mode conscious. Izno (talk) 17:59, 28 October 2024 (UTC)

And I gather this is about Module:Rugby league match squad. While you can do something of the "if this isn't defined, use the basic colors", you still need to cover your bases when it is defined. Basically you have these options in that case:

1. Remove custom color support with its obvious downside. Branding is not that important, and that's almost exclusively the reason that a module like this uses color.
2. Apply hue-rotate using a TemplateStyles sheet. This will result in the branding color being incorrect but the table will be dark rather than light.
3. Forcibly override any colors inserted using TemplateStyles and !important while in dark mode. Anything using !important is usually considered to be technical debt, but at least your table is dark.
4. Live with light mode colors for both light and dark. Which preserves the branding information but makes someone using dark mode have to put goggles on. :)

That's it. That's the story. You won't get everything you want all in one nice package. :( Izno (talk) 18:08, 28 October 2024 (UTC)

@Izno thanks. I'd go for #1 but as I seem to be in a minority about colours among rugby editors, I can see it being reverted. I'll see what I can work out about template styles (have to say that what there is on the subject here and on media wiki isn't very helpful) and look at #3. Nthep (talk) 09:03, 29 October 2024 (UTC)

@Izno Thanks again. I managed to adapt Module:Rugby league match squad/sandbox and it's calling template to use TemplateStyles ({{Rugby league match squad/sandbox/styles.css}} which seems to work ok on my sandbox [1].

I'm conscious that the module isn't the greatest piece of coding and is at serious risk of becoming an unitelligible mish-mash of code and styling. I see that TemplateStyles can be called from a module using frame:extensionTag (mw:Help:TemplateStyles#How_can_Lua_modules_interact_with_styles?) and my thought is could all the styling could all be pulled out into TemplateStyles using function p.templateStyle( frame, src )? Nthep (talk) 21:23, 5 November 2024 (UTC)

You can do something like this at the very end of main():

return table.concat ({
		frame:extensionTag ('templatestyles', '', {src='Rugby league match squad/sandbox/styles.css'}),
		return_t
		});

Yes, I would recommend placing the styles all in the sheet, at least those which can be. The above is the function call version, barring that I moved the TemplateStyles page just now. The object call version of it looks like

frame:extensionTag { name = 'templatestyles', args = {src='Module:Rugby league match squad/sandbox/styles.css'}}

(which I prefer since it names the arguments to extensionTag). I normally just concatenate it like your general string, but of course you may need tostring the return item depending on what you're concatenating e.g.

local templatestyles = above_bit return templatestyles .. return_t

Thank you both for the replies, I will have a mess around and see where I get to. Doubtless I will be back with more questions. Nthep (talk) 10:52, 6 November 2024 (UTC)

Please help me in creating a page Module:Sandbox/பொதுஉதவி. பொதுஉதவி (talk) 05:48, 1 November 2024 (UTC)

I've gone ahead and made the page at Module:Sandbox/பொதுஉதவி. I assume the title blacklist was the only issue? Aidan9382 _(talk) 08:33, 1 November 2024 (UTC)

Using #invoke in mainspace, as an alternative to templates

I've come across List of common misconceptions, which uses {{#invoke:cite web|}} instead of using {{cite web}} (and other CS1 templates) directly. Is this a good idea, or discouraged? --Yodin^T 18:15, 17 November 2024 (UTC)

It's a necessary evil when working with huge articles that would otherwise exceed the post-expand include size. Otherwise it's discouraged. * Pppery * _{it has begun...} 18:18, 17 November 2024 (UTC)

Output unreadable with "2-ary truth table" template

The template uses Lua whose output is unreadable with Wikipedia's "Vector (2022)" dark mode skin.

As you can see, Template:2-ary_truth_table uses Lua whose output is unreadable with Wikipedia's "Vector (2022)" dark mode skin. Chai T. Rex (talk) 07:39, 26 November 2024 (UTC)

@Chai T. Rex It already has a Wikipedia:TemplateStyles stylesheet, Template:2-ary truth table/style.css, so it's a question of editing that to include some dark mode options. Is it just the text colour in the third column that's the issue? Nthep (talk) 13:38, 26 November 2024 (UTC)

Yes, the third column is unreadable. Chai T. Rex (talk) 21:06, 26 November 2024 (UTC)

If there is no further help here, ask at WP:VPT what is needed in that css page. Johnuniq (talk) 01:32, 27 November 2024 (UTC)
