I just learn that ``\\`` to force line break in TikZ node text only work in top level.
(Fixing is not very hard, but error message isn't that good)

In MathJax room there was a short discussion on writing expressions with quantifiers.
I would consider it more a discussion about typography than about some LaTeX/MathJax-related technical issue. (I'd say that the aspect which is being discussed is the same for MathJax and LaTeX.)
Maybe some TeX - LaTeX users could have something to add there. Link to the conversation: Spacing in expressions with quantifiers.
And I see that this question on the main site might be related: Best practice for typesetting quantifiers?
 
6:44 AM
@user202729 a tikz node with specified with is a minipage and \\ works wherever it works in a minipage, I don't understand what you mean by top level there
@MartinSleziak i'd never use outer parenthesis around the quantifier, you can compress \in as {\in}
@MartinSleziak I didn't know we had a mathjax room, perhaps the mathjax tag wiki here should mention that
 
By "top level" I mean "not inside any group" (I tried \textbf{line 1 \\ line 2}, which doesn't work while \textbf{line 1} \\ \textbf{line 2} works), but okay
 
@user202729 you must be doing something strange (unless you are in math in which case \textbf is an unbreakable box, but that's unrelated to tikz, \\ in text would be unaffected by \textbf with standard definitions
 
@DavidCarlisle It depends on who is we in that sentence - the room I linked to is associated with Mathematics, not with TeX - LaTeX. (Here are math rooms and TeX rooms.)
Of course, the there is an overlap between the users of these two sites.
 
@MartinSleziak yes I meant the stackexchange network I guess, but the most common reason for getting mathjax questions here is someone has a problem with it posting to one of the mj enabled sites in the network so that would be a good place (since they often get closed here)

I use with [align] (suggested in tex.stackexchange.com/questions/123671/… )
The other option (text width) does work.
Not that it matters much.fontstyle=\bfseries is also okay.
 
@user202729 oh forgot about that, that will be a tabular you can't end a table row inside {..} (so exactly what you said, \\ has to be outside any group:-)
 
8:43 AM
ooh weeping angels are back
 
9:37 AM
Can someone tell me what \pgfsyspdfmark is for? I can't find out much about it. The hits on TeX SE mostly seem to relate to corrupt aux files and suchlike.
 
@LaTeXereXeTaL Cool, that's awesome! I've never seen one, but I remember the design!
@LaTeXereXeTaL That design was indeed very charming! I still have a 2007 MacBook around (first model with an Intel chipset), with a memory upgrade and running Fedora. :) I think it was the last one with the white design + glowing apple in the lid.
@LaTeXereXeTaL I bravely kept MacOS running on my iMac up to High Sierra, I guess. At that point, I had it as a Unix box (living inside the terminal, basically), but then Homebrew dropped support for it, so any further updates to the installed packages had to be compiled from source. My daily routine involved +3 hours of heavy compilation, so I gave up on MacOS and installed Linux. Couldn't be happier. :)
 
10:34 AM
@FaheemMitha without looking I assume it's for adding pdfmarks defined using whatever the backend needs (lualtex/dvips/dvipdfmx etc)
 
@DavidCarlisle Ah. I thought knowing more about it might help with the debugging, but perhaps not.
 
10:45 AM
@DavidCarlisle saw your comment way too late :)
 
@Skillmon no one will believe you, I'm sure you needed such a comment from a tikz gold badge expert to get you started.
 
@DavidCarlisle The main issue was that I had to look up starting from which compat my code will work :)
 
@Skillmon you should have added some command hook calls to ensure it wouldn't run on anything older than tl2021
 
@DavidCarlisle sorry, but I couldn't think of a useful application of hooks here.
 
@DavidCarlisle ooh
 
10:49 AM
@Skillmon \AddToHook{whatever}{\typeout{if this doesn't work, I have no sympathy}]
 
@Skillmon hi mr. rabbit! miss you! <3
@DavidCarlisle ooh
 
@PauloCereda Hi, Mr. Duck! Sorry for being relatively inactive lately :) Got some real life stuff that needs to be sorted :(
 
 
1 hour later…
12:15 PM
@PauloCereda I just recalled another funny "language mix up" case, related to the "pauladas". Not long ago a new cosmetics store opened just a couple of blocks from my house. And they decided that it might be fancy to go with a French sounding name. So they went with "Le Batom". When I saw it the first time I just cracked! And still laugh every time I pass by. I can even imagine the slogan: "Come and get your eyelids purple!" :-)
@AlanMunn ^^
 
12:40 PM
@gusbrs hahaha excellent
 
12:52 PM
@PauloCereda scenes from provincial life :)
 
@gusbrs colourful landscapes :)
 
@PauloCereda well, it makes for some curious situations and cases. In the case at hand, it is even funnier because it is meant as a fancy store. It is clearly pumped up for the local standards. As for me, I'm probably just "that highbrow guy" (em terra de cego...).
 
@gusbrs :D
 
@PauloCereda ;-)
 
@gusbrs One day my dad and I were walking in the food court of a mall in a nearby city. My dad suddenly said, Nossa, o que é isso? Eu quero comer potatões! It was a decked potatoes food service. :)
@gusbrs this one was curious: One day, while I was working, my dad turned to me and said, Filho, o que é BibTeX? I shed a tear, Sério, pai?! Nossa, vou te explicar direitinho! Then I realized he was reading an article that said big tech and not BibTeX. :)
 
1:04 PM
@PauloCereda I don't know what "decked" potatoes are supposed to be. But I presume your dad got the right meaning just taking a different path. :)
 
@gusbrs life finds a way, specially when stomach and hunger are involved. :)
 
@PauloCereda This is what I call "wishful hearing"...
 
@gusbrs My dad says lots of funny things. :)
 
@PauloCereda Oh yeah! And you bet "Le Batom" is making success, everyone understands what they thought they were saying. :D
 
@gusbrs hahaha
 
1:08 PM
@PauloCereda :)
 
@gusbrs mind if I ask which city are you located in MG?
Or its whereabouts
 
Of course, Juiz de Fora. "carioca do brejo! ;-)
 
@gusbrs uia
@gusbrs pó pô pó? Pó pô :)
 
@PauloCereda Or "Av. Brasil, 204553"
@PauloCereda Pó! Nuuuu!
 
@gusbrs hahaha
@gusbrs modi comprá um lidileite :)
(^^ I speak like this)
 
1:16 PM
@PauloCereda I can imagine! Of course, being myself a paulistano, I'd say you have an accent. ;)
 
@gusbrs I tried my best to hold my accent while in SP, but one day it didn't work: I asked a colleague to hold the elevator door, Ô moça, seguRa a poRRRta do elevadoRRR!
 
@PauloCereda "porta" is the killer! hahaha
@PauloCereda I must be off now. Cheers!
 
@gusbrs true :)
@gusbrs Have an awesome day!
 
1:38 PM
@PauloCereda Você deveria falar português com um sotaque europeu perfeito, como eu,
 
@DavidCarlisle ooh
 
1:52 PM
@PauloCereda O que os romanos já fizeram por nós?
 
2:47 PM
@DavidCarlisle o aqueduto?
 
2:59 PM
@PauloCereda Quantos aquedutos brasileiros os romanos construíram?
 
@DavidCarlisle oh
 
3:17 PM
@DavidCarlisle no picture mode? (I especially like the pac-man, btw)
 
@Rmano should we suggest he should write about some more recent arithmetic and use xistercian instead?
 
@Skillmon oh yes, would be nice ;-).
 
@Rmano it was a bit pacman-ish I admit, perhaps the ancient Egyptians had video games
 
@DavidCarlisle MANY THANKS for the {\in} suggestion (compressing the spaces around the element symbol)!
 
3:32 PM
@RyanG I hoped that worked in mathjax as well as tex, I didn't actually check:-)
 
@Rmano I can't decide - does 1000 look like a flower or like a cat?
 
@DavidCarlisle It does. Woohoo!
 
@samcarter hmmm... a flower in a pot
 
@Rmano I do have history with mspaint artwork

A: Multiple captions under a single figure

David CarlisleYou can have as many \caption as you need in a figure \documentclass{article} \usepackage{graphicx} \begin{document} \listoffigures \begin{figure}[thp] \begin{minipage}{.5\textwidth} \centering \includegraphics{man} \caption{man} \end{minipage}% \begin{minipage}{.5\textwidth} \centering \in...

 
@Rmano don't forget to water the numbers - otherwise the equations won't work :)
 
3:42 PM
@samcarter you should show the latest hieroglyph translation...

@UlrikeFischer as you wish :)
 
@samcarter يبدو صحيحا
 
@DavidCarlisle oh no :)
 
4:02 PM
@samcarter ;-)
 
@UlrikeFischer During the first lockdown, the Frick Collection had a video format "Travel with a curator" in which they showed photos from previous trips. The bear could make "Travel with a bear" stories :)
 
5:02 PM
Hello everyone! Sorry for bothering you, I'm looking for a way to compile tex documents to get both a pdf file and html pages as an output. Is there anything like that, that you know of?
An example of that could be bookdown.org, but I have a few things against it, one of which is, it doesn't take latex as an input, but files written in R markdown, afaik
 
@MarcelKrüger I just saw on the texlive list, that someone has a problem with the new \pdfgentounicode=1: the cmap breaks if one converts the pdf with ps2pdf to another pdf.
 
5:54 PM
@Ottavio Have you already tried tug.org/tex4ht ?
 
6:19 PM
@samcarter I haven't, I'm gonna look it up, thanks!
 
6:32 PM
@UlrikeFischer I've seen, but there isn't much we can do about it. There already is a GhostScript bug report about it, but tl;dr: The GhostScript developer would like all CMap's to map to single codepoints (which would make the documents worse for all other consumers) and considers the issue to be rather unimportant anyway. I left a comment there to support our approach, but it doesn't sound like we should expect a fix anytime soon.
 
@MarcelKrüger ah, well "We (not unreasonably I feel) expect that a single character code should map to a single Unicode code point" is an interesting point of view ;-)
 
@samcarter LOL
 
7:07 PM
@UlrikeFischer and @MarcelKrüger -- Even the Unicode Technical Committee has wavered on that point, by providing "variation selectors". Most recent addition to those is the "addition" by this method of calligraphic script to the "formal" script shown in the Unicode charts. The "same" letter in both scripts can have different meanings in a single math paper, and actual examples of this usage was what forced the UTC to make that decision. Might that argument have any weight?
 
@barbarabeeton I don't think that one need subtil arguments here. The general idea that there is an one-to-one relationship from glyphs in a font to unicode code points is simply wrong as lots of ligatures proves.
 
@UlrikeFischer -- and Unicode doesn't have a ligature for "fj". Quite short-sighted, in my opinion. (Oh, I've got lots of objections to some Unicode decisions. Getting the math alphanumerics accepted was a struggle, but they had to give in when faced with actual practice in math and technical literature. That argument is not particularly subtle!)
 
@barbarabeeton well imho it was wrong to add the fi and ff ligature as unicode code points. Making a ligature is a "shaping" decision, and not related to the meaning.
 
7:24 PM
@UlrikeFischer they came in from legacy enclodings and were probably politically necessary to get an agreed encoding at all
 
@DavidCarlisle yes, and we can live with them like with other historical remains. But one wouldn't get discussions like the one on the gs list if they weren't there ;-).
 
@UlrikeFischer -- Those are "legacy" items. As are quite a few items in the U+2300 block, in particular the vertically split integral, sum, and fences. Unfortunately, the membership of the UTC is a bit short on actual scientists. And @DavidCarlisle is correct about the politics.
 
7:50 PM
@UlrikeFischer yes that wasn't the response I expected:-)
 
8:25 PM
@UlrikeFischer @JosephWright planning to merge github.com/latex3/latex2e/pull/342 ? (looking down list of PRs)
 
@DavidCarlisle hm, my last comment was that it is fine, I wonder if I meant it ;-)
