I created the spelling and grammar checking project at Wikipedia:Typo Team/moss. If you are responding to an edit related to special characters, language tags, or manual of style compliance, HTML cleanup or markup issues, it might have been motivated by some report generated by that project. -- Beland (talk) 03:52, 9 July 2021 (UTC)

Hi, just wanted to let you know that I have decided not to pursue this merge. I did a lot of work to reduce keyboard layout/keyboard technology/computer keyboard triplication, ending with clearing out the last of these to make it a redirect. It has all been undone and I don't have the inclination to pursue it to the bitter end, I just don't care that much. I can't see why the RTM that we have discussed would have any different result. If you want to go ahead anyway, feel free. --John Maynard Friedman (talk) 10:56, 26 August 2021 (UTC)

Coherent style for formulas

In Nilpotent Lie algebra, you introduced recently the awful formula {{math|''n'' ∈ <math>\mathbb{N}</math>}}. I have changed it into <math>n\in\mathbb{N}</math>. Please, avoid mixing latex and html rendering in the same formula.

Happy new year. D.Lazard (talk) 09:42, 31 December 2021 (UTC)

@D.Lazard: Yeah, it's definitely more readable when it's all in LaTeX. I've just been going through making articles compliant with MOS:BBB, which only requires changing over the blackboard bold characters. I had been converting relatively simple formulas to LaTeX completely, but it got a bit time consuming, and some longer formulas were quite daunting. MOS:MATH doesn't say anything about not mixing the two, so my thinking was that the mixed style was at least MOS-compliant, and we could go back and convert the rest of the markup later. I was hoping some other editors skilled in LaTeX would be able to help with that. Would you be able to help with some conversions? I see 88 articles with mixed markup (not all of which are from my edits) and several hundred articles with ℝ, ℤ, or ℂ. We could also add a note to MOS:MATH saying not to mix LaTeX and HTML, and resolve to do blackboard-bold-motivated conversions in one step rather than two? -- Beland (talk) 18:59, 31 December 2021 (UTC)

Well, I added the note to MOS:MATH and put the mixed markup pages on my personal cleanup todo list. It may be a few months before I get to all of them, as there are thousands of articles in my cleanup queue. -- Beland (talk) 22:36, 2 June 2022 (UTC)

Did a few of these today. Note to myself, use edit summary:

per [[MOS:FORMULA]], do not mix LaTeX and {{math}} in the same expression

List of possible chemical formulas that don't use subscripts

Hello! I have recently been fixing typos from moss and I see there is a list of possible chemical formulas that don't use subscripts. I was wondering a couple of things:

• what do the numbers on the left of the entries mean?　For example 16/5 - H3S10

• are they for reference only, or would it be in any way helpful to investigate and tag them with their common names, if they are indeed chemical formulae?

Thanks and happy typo hunting 😄 rbstrachan (talk) 19:41, 5 August 2022 (UTC)

Greetings! The first is the number of instances this possible formula was found, and the second is the number of pages. So in this instance, H3S10 was found 16 times across 5 pages. It looks like Graeme Bartlett already determined it is not a chemical formula and made a redirect for H3S10, so I took that off the list. That's a preferred way to fix items that are not chemical formulas if they have articles. The spell checker won't care if you make it a link or not, but it might help readers to do so.

Yes, the general intention is to investigate each, determine if they are actually a chemical formula, and update the markup accordingly. There's a full list of suggestions of what to do at Wikipedia:Typo Team/moss#Chemical formulas.

The idea of using the common name to link these to articles is interesting, and something I hadn't really thought about. The spell checker doesn't really care if there's a link or not; it only looks at the display text. So, it will complain about both "H20" and "H2O" ("[[water|H2O]]") because the manual of style says it should be H₂O (using {{chem2}}). Turning that into a link would make it H₂O, which is a bit ugly but potentially helpful to the reader. Sometimes there's a very technical context, and the problem text shows up in chemical equations or something, where putting words (like "water") wouldn't make sense. In that case, we probably don't need a link anyway, and fixing the typography is all that's needed. Sometimes having the name instead of the formula would make the article easier to read, so switching it out and making it a link would be an improvement; you'd have to use your judgement.

I suspect most or all of these either aren't chemical formulas or don't have chemical substance articles we can point to, so the suggestion to add links to chemical articles might apply more to Wikipedia:Typo Team/moss#Known chemical formulas that don't use subscripts, where there usually is an article.

Poking at the "Possible" list just now, I had a bit of trouble figuring out which articles the spell checker was complaining about. I put a note at the top explaining how to use the "insource://" trick, which should be sufficient until I can get those included in the report automatically (or we empty out this list). Thanks for your interesting question and your ongoing cleanup work! -- Beland (talk) 08:09, 8 August 2022 (UTC)

(talk page stalker) Just out of curiosity, is there a comparable list of chemical formulas that don't contain numbers (like HNO and NaCl), and therefore could be mistaken for words? BD2412 T 22:39, 8 August 2022 (UTC)

That's an interesting question! While thinking about it, I thought of another, related question.

While converting chemical formulae written with HTML <sub> tags to use the {{chem2}} template, should element names such as In, Fe, etc. and chemical formulas that don't contain numbers, such as HNO and NaCl as you mentioned, also be converted?

On one hand, I'm not sure that it's worth adding the bulk of a template for things that don't technically need them and which don't benefit from a visual improvement to the way they are displayed. On the other hand, it may reduce the number of false positives for projects like WP:TT/M.

One of the main reasons that I can see for converting HTML tags to the {{chem2}} template is to make it possible to search Wikipedia for chemical formulae without having to resort to regex. Having said that, since elements and most basic chemical formulas don't contain numbers, they don't contain <sub> tags, so making them use the {{chem2}} template would not do anything to make them more easily searchable.

In regards to both of our questions I do vaguely remember reading somewhere that the Moss scripts ignore capitalised words, and as elements and chemical formulas (should) always start with a capital, these may not be issues in the first place. 😅

😊 — rbstrachan (talk) 23:34, 8 August 2022 (UTC)

That's right, for spell-checking purposes moss ignores capitalized words made of only letters, on the assumption they are proper nouns. (These problem formulas are actually pulled from a list of ignored but suspicious words.) Even when I stop doing that (because I want to verify the spellings of proper nouns) most of the ones without numbers would have articles or redirects, so they would still be ignored. The only reason they became an issue for moss is that not using subscripts violates Wikipedia:Manual of Style/Chemistry#Symbols and Unicode subscripts violate MOS:SUBSCRIPT.

There may be other reasons to wrap these formulas, though, such as for accessibility. It doesn't look like they are currently adding alt text, but if you use "auto=yes" with {{chem2}}, it does link each element symbol to the article on that element. I'm not sure if that's something we should be doing everywhere or nowhere? It might be worth checking with Graham87 (who uses a screen reader and who helped figure out how to handle fractions) or Wikipedia:WikiProject Accessibility or Wikipedia:WikiProject Chemistry to see if anyone has any particular preferences. -- Beland (talk) 01:36, 9 August 2022 (UTC)

Watch out for Hebrew letters

Hebrew is written right to left, unlike English which is written left to right. So the character following a Hebrew letter like Aleph will appear to its left rather than to its right. This causes a problem when the Hebrew letter is intended to be part of an English text rather than a Hebrew text. You have twice ignored this fact when replacing ℵ₀ with א₀ at Cardinality of the continuum.

More generally, you should always look at the resulting text as it is displayed to the ordinary user and make sure that it is what you want it to be. JRSpriggs (talk) 14:45, 31 January 2023 (UTC)

@JRSpriggs: Ah, thanks for the note! I hadn't noticed that I had made the same edit before. That's surprising that the character and the HTML entity have different text direction behavior; I'll be on the lookout for that in the future. -- Beland (talk) 16:35, 31 January 2023 (UTC)

Edits to 744

Hello Beland. Thank you for your help on the page for 744 (number). I don't know that MOS:BBB (1) is needed here, only a couple of "special characters" I am going to keep with {{math}} rather than LaTeX, and while a very select few phones and other displays might have trouble with it, it's really not an issue, I have a burner phone and it reads just fine (on the other hand low quality Android devices will generally not read <math> in a note, and I think it's the same for other phones with similar operating systems, for some reason. Mine does not read it, iPhones do not have an issue with this). My intention is to dichotomize the <math> to main text and {{math}} to the notes, that way there is a breathing space for readers to see another style, and connect it with a note for like-information that helps contextualize the main text. Also, for your most recent edit 2 you accidentally left a "}}" which took out part of the note into main text (around line 166 in 2 to be specific). Those subscripts that you took out that were in {{math}} tags still and blended with LaTeX, you left in when you had originally converted only the special characters, see 1. Thank you again, and happy editing! Radlrb (talk) 17:16, 12 March 2024 (UTC)

@Radlrb: Ah, thanks for catching that syntax error! This page is a little overwhelmingly long, and I didn't spot it when checking my changes. I'm a bit unclear on what you mean that MOS:BBB isn't "needed"? Do you mean you're planning to convert expressions like <math>\mathbb{Z}</math> to regular bold like Z, or you're planning to use raw Unicode characters like ℤ? The former is fine, but the latter would violate the English Wikipedia Manual of Style. -- Beland (talk) 22:28, 12 March 2024 (UTC)

@RadlrbI can help you. Langalakh (talk) 17:32, 12 May 2024 (UTC)

@Radlrb what's that I'm confused. Langalakh (talk) 22:48, 12 May 2024 (UTC)

Please stop converting thin spaces to ordinary spaces in mathematical typography.

Edits such as special:diff/1219321937, which in part converted some explicit thin spaces in mathematical typography to ordinary spaces, are not helpful. If another editor explicitly chose a size of space to stick into a formula, you should assume they did so for an intentional reason and not automatically second-guess that decision. Often regular spaces leave formulas written using plain wikimarkup (e.g. in {{math}} templates) looking incorrect, and explicit hair spaces or thin spaces make the formula appear more correctly. –jacobolus (t) 01:53, 17 April 2024 (UTC)

@Jacobolus: In my experience, thin and hair spaces usually aren't necessary, and can sometimes cause excess whitespace. This is a good reason to keep markup simple, along with reducing the skill burden of learning wikitext so we can attract and retain editors. The version of Tensor with those removed renders correctly for me. Sometimes different operating systems and web browsers and fonts render characters like these in an overlapping way; I would consider that a bug in that stack which should be reported and fixed. But once that happens, we don't need to keep these characters around forever. Does the version without thin and hair spaces render incorrectly for you? It looks like Cedar101 may have been the first editor to introduce this character in 2017; pinging them to see if they are (still) having typographical problems. -- Beland (talk) 02:12, 17 April 2024 (UTC)

I am extremely dubious of the evidence-free claim that editors of very mathematical pages are deterred by the presence of occasional explicit unicode characters. But I can tell you for certain that good editors are highly discouraged by having their careful deliberate choices trampled by lazy automated regressions.

The version of Tensor with the full-sized spaces is definitely worse than the version with thin spaces, and it is clear why the thin spaces were originally chosen. If you feel like it you are welcome to rewrite the whole page using LaTeX instead, which looks better and has simpler markup, but please stop automatically breaking people's intentional choices in mathematical typography. –jacobolus (t) 03:27, 17 April 2024 (UTC)

@Jacobolus: Ah, your comment pointed out that I added space rather than removing it, which I missed. I would have expected the latter to generate complaints about overlapping text characters. I'm surprised that the complaint is that there was too much space; a full space is normally a safe substitution. It turns out I actually get overlapping characters myself with no space there, so I'll see what I can do to get that fixed. In the meantime, I'll use {{thinsp}} since those are generally a sign that someone is intentionally using a thin space in wikitext. (And it's nice that templates can have documentation to explain what they mean and why they are being used.) HTML entities are often automatically imported from other environments rather than being inserted intentionally.

A high difficulty of editing can result from an accumulation of small difficulties, which new editors sometimes must confront all at once to make useful contributions. Much of the point of wikitext is to spare editors from having to learn HTML, though it's reasonable to expect deeply involved math editors to know LaTeX. But it seems a bit much to expect, say, a math professor who already knows LaTeX to learn wikitext and HTML syntax if one of those isn't really necessary. Perhaps the added difficulty is more pronounced for articles where there isn't already a lot of complicated mathematical markup, but that is most of them. -- Beland (talk) 16:34, 17 April 2024 (UTC)

Wikitext is built on HTML, and HTML entities are a basic feature. Using {{thinsp}} instead of   is not substantially beneficial. The template is not inherently more accessible, being a weird english-wikipedia-ism that someone has to go do a search to learn about instead of a common standard used across the web.

If you are writing a new page, feel free to use either one. But please don't do automatic replacements of one for another (not sure if you were planning on it). At best it creates pointless watchlist spam. From what I can tell this kind change does not have (and should not have) the backing of any sitewide policy. –jacobolus (t) 17:12, 17 April 2024 (UTC)

@Jacobolus: I generally assume that editors have to learn how to use Wikipedia templates, because they are used in pretty much every article, usually quite frequently. Wikification, where we replace web-standard HTML tags (which do work without modification) with Wikipedia-specific markup, is a general directive, and indeed the whole point of Wikipedia:WikiProject Wikify. That wouldn't be necessary if we weren't trying to save people from learning HTML. I wasn't planning to mindlessly swap thin space HTML entities for templates, but at some point I will probably do a pass through the entire project to remove inappropriate ones. As you can see, most of the existing instances are not in math articles, are not fixing problems with overlapping characters, and do not align with our usual style. -- Beland (talk) 17:28, 17 April 2024 (UTC)

This seems like a huge waste of time. Most of the examples of thin spaces from your link seem deliberate, and don't seem to be harming anything. –jacobolus (t) 17:33, 17 April 2024 (UTC)

@Jacobolus: Well, the first instance, on Kazakhstan, actually is breaking the citation template, causing the string "&thinsp," to show up in the article. Even if it was working properly, a non-ASCII space would be polluting downstream data for citation consumers. (For example, journal web sites that list all Wikipedia references to papers on that paper's page.) The Pirate Bay is also polluting a citation template.

In the second article, Moon, the usage violates MOS:UNITNAMES, which specifies a full, non-breaking space between a number and a unit abbreviation. It looks sloppy to have different amounts of whitespace in different measurement expressions.

In the third article, Amazon (company), the usage violates MOS:$, which specifies no space after "US$" and a full, non-breaking space before "million". It looks sloppy to have different amounts of whitespace in different instances of currency expressions. Apartheid is breaking the same rule.

And so on. -- Beland (talk) 22:21, 17 April 2024 (UTC)
