@barbarabeeton It should probably begin and end with β€œ$\aleph_0$ bugs in the code”.
 
8:00 AM
@HaraldHanche-Olsen Unless it is my code of course, when you can miss out the \aleph_ part
 
8:56 AM
suppose I wanted to print some statistics to the terminal during compilation, how can I use escape characters so my *nix shell colourizes the output? When I try to include them in \typeout fontenc cries out because they are not setup for use in LaTeX.
 
9:09 AM
@Skillmon inputenc not fontenc but \typeout{\detokenize{...}} probably works. (but you may need -8bit to stop pdftex showing control character in ^^A notation
 
9:37 AM
@DavidCarlisle do you know an online converter to convert a surrogate pair like D875DC53 to the unicode code point? (I'm trying to understand how (unicode-)math is stored in the pdf).
 
@egreg yes but 2D453 is not a unicode point. So either the calculator is wrong or I don't understand the pdf ;-(
 
9:53 AM
@UlrikeFischer yes
@UlrikeFischer or more helpful answer add them as two "UTF-16 units" here r12a.github.io/app-conversion
 
@DavidCarlisle @egreg I think I found a bug in luatex. A mathematical italic f is mapped in the pdf to this utf16 points:
lualatex:  D875DC53
xelatex:   D835DC53
context:   D875DC53
 
@DavidCarlisle yeah, inputenc, my bad. I'll try \detokenize.
@DavidCarlisle \detokenize it is.
 
10:14 AM
@UlrikeFischer is this in tagging somewhere? presumably the italic f glyph is found?
@UlrikeFischer ah so that's U+2D453 instead of U+1D453 out by one in the most significant digit :-) (@egreg)
 
@DavidCarlisle I wrote to the context list. It is either an engine or a fontloader bug, so Hans should handle it ...
 
@UlrikeFischer he could use harfbuzz
 
@DavidCarlisle ;-). I don't understand r12a.github.io/app-conversion. Where should I copy "D875DC53"? And on which of the button should I then click?
@DavidCarlisle ok I got it by doing some reverse engeneering. It should go in "UTF-16 code units" and one should add spaces D835 DC53.
 
10:33 AM
@UlrikeFischer yes or actually I added spaces and used the utf16 box ^^^ basically you can add more or less anything somewhere and it will do something:-)
@UlrikeFischer that's from Richard Ishida, Internationalization lead at the W3C, I use it a lot:-)
 
@DavidCarlisle yes, it looks very useful. I just marked it.

12:28 PM
Hello everyone,

I have an error driving me crazy. After playing with my code, I receive an error of the existence of fontspec package. So, how can I know what loads it?
 
12:39 PM
@Diaa the log file shows you what file is open, start from the error and go back to the nearest unmatched (
@Diaa but why have you not got fontspec?
 
12:51 PM
@DavidCarlisle Hans found the error (v = instead of k = somewhere ...).
 
@UlrikeFischer :-)
 
@DavidCarlisle and it was a rather new error introduced in april - which explains why no one complained about it. We would have needed @JosephWright pdf-testing to catch this :-)
 
@UlrikeFischer enjoying life at the cutting edge? :-)
 
1:10 PM
@DavidCarlisle a bit ;-)
 
1:24 PM
@UlrikeFischer I don't suppose you had any contact re luaotfload updates?
 
@DavidCarlisle No sadly not ;-( I would have told you if something had happened.
 
1:52 PM
Does anyone know if there are canonical/official Docker images for (past and) present TeX Live versions? (Maybe @egreg, @DavidCarlisle, @JosephWright, or others would know?) I didn't see anything from a quick google search, but maybe I missed something? πŸ™ƒ
 
@AdamLiter Never heard about it
 
@AdamLiter Maybe this one from dante can help? hub.docker.com/r/danteev/texlive
 
Thanks @egreg.
And thanks @samcarter. That link is helpful. I've come across a few other one-off Docker images like that, but I was hoping to find a set of images for at least the last few versions of TeX Live, too. But I'll probably use the one you linked to and some of the others I've found for inspiration when making images for a couple of the recent versions of TeX Live.
 
2:09 PM
@AdamLiter At the last Dante meeting one of the talks was about using tex in docker etc. The repository for the image presented there is github.com/dante-ev/docker-texlive
 
@DavidCarlisle I found that the error came from standalone where it didn't reset its *.sta file that was generated before using lualatex and fontspec.
 
Hey @AdamLiter!
 
@samcarter Thanks! This looks really helpful.
Hi @PauloCereda! πŸ¦† How's it going? Congrats again on the arara release. πŸ™ƒ
 
@AdamLiter In a hurry, as usual, but fine. :) And you? Thanks, glad you like it!
Hmm imgur is down?
 
@PauloCereda Hahah, that's a great picture. I'm good. In a hurry, too. I'm trying to get a lot of stuff done before classes start back up again for me ...
 
2:30 PM
@AdamLiter ooh :)
@DavidCarlisle ^^
 
@marmot Maybe you should undelete your answer tex.stackexchange.com/a/445165/36296 - it seems this is what the OP wants.
 
2:45 PM
@samcarter How about you just add these things? Your answer is clearly better (and you were faster ;-)
 
@marmot Thanks for the offer, but I don't really like the idea to decrease perfectly fine inter word spaces.
 
@samcarter I could tell him in a comment, then I would be the bad boy, errr marmot ;)
 
@marmot Sounds like a good solution - nobody could be angry with marmots :)
@marmot btw: how much longer do we have to wait until your 3D user image? I'm looking forward to it!
@PauloCereda You'll have to be extra nice to your cats today: en.wikipedia.org/wiki/International_Cat_Day
 
@samcarter I thought there is a 30 days period before one can change the profile again. BTW, these days, in which imgur got a cold, are probably the days in which one shouldn't do that anyway. I guess when imgur has recovered would be a good time, what do you think?
 
3:00 PM
@samcarter yay
 
@marmot mmmm, maybe pouring a couple of bottles of cold meds over the imgur servers will help :)
 
@samcarter Or honey liquor. I just don't want to share it with imgur, I prefer sharing it with my fellow marmots. ;-)
 
@marmot :)
 
3:18 PM

@PauloCereda @samcarter ^^^^
 
@AdamLiter I know nothing:-)
 
@UlrikeFischer That is great! However now I am wondering what the name for this fear is :)
 
@AdamLiter For the team stuff, we don't use fixed images but rather install vanilla TL and cache: we want to know that code in third party packages doesn't get broken ...
 
3:35 PM
Do you see images?
 
@egreg Some people can, some people cannot.
 
@samcarter What I thought. Umph.
 
@egreg And still no official reply on any of the meta posts :(
 
3:57 PM
@samcarter I cannot.
 
@egreg -- for one link this morning, it failed at first, but then appeared by itself. for two links, still no images. and yet another, appeared without a prompt. very erratic.
 
@JosephWright Thanks for the info. I think you could in principle do the same thing with Docker and just run tlmgr update in the Docker container before compiling or testing anything. There's probably no good reason to (dis)prefer this, though. But I was thinking about Docker because I'm considering building out some images for recent versions of TeX Live in order to test example code for a LaTeX tutorial that I have.
Then I could show people who view the tutorial which versions of TeX Live they can expect the examples to work with.
(With the caveat, of course, that people should update to the latest version. But I find that many new LaTeX users don't often do that ...)
 
@AdamLiter Sure: it's just that for us, Docker isn't necessary (if we wanted a 'fixed' version on Travis-CI, we'd use the Ubuntu packages, as they are cached too)
 
@JosephWright Yeah, that makes sense. Thanks for the info and discussion! 😊
 
 
1 hour later…
5:22 PM
@PauloCereda I can see your avatar, David's and Joseph's, but not mine, samcarter's and barbara's.
 
5:36 PM
@egreg How about mine? (I can see yours...)
 
@marmot No animal in sight
@marmot But I know it's quite difficult to see marmots.
 
This doesn't answer my question, marmots are *beings*!
Perhaps even odder: in the answers to [this question](https://tex.stackexchange.com/q/445167/121799), I can only see the output of current_user's answer....
 
@marmot No images at all
 
@egreg Did you drink? ;-)
 
@marmot No. :-)
@marmot No train during holidays
 
5:41 PM
@egreg You should. It's pretty hot these days.
 
@marmot Do marmots drink a lot?
 
@egreg Only special wheat beer and honey liquor, but not a lot. ;-)
@egreg Can you see the pic in tex.stackexchange.com/q/445199/121799 ? I can.
 
@egreg -- i can see all avatars, but i've still got the session up that i opened yesterday. so it's only today's connections, but oddly, one of those is present on the screen from its posting, and one will respond to a click. several others get the "page isn't redirecting" response to a click. and as for the question linked by @marmot, absolutely no images at all. definitely troubles.
 
6:18 PM
@PauloCereda That is too bad! How shall I sent you duck pictures if you cannot see them? Ducksay package to the rescue!

@samcarter yay, someone except myself used it!
 
@Skillmon Your package is a lifesaver in times without images :)
 
7:21 PM
I just noticed, that texdoc ducksay only displays the readme :(

@samcarter
 
I can see avatars and images that I previously couldn't if I hard refresh with Shift + F5. If anyone is still struggling with this issue.
 
8:08 PM
Images are back for me! :-D
 
@egreg the quick rise and fall of ascii art
 
@Skillmon Well, just for a couple of minutes. :-O
 
8:40 PM
Oh no, my avatar got eaten by a black hole. Nasty black hole I should say.
 
9:07 PM
@marmot come out of the hole, and squeak
 
@DavidCarlisle My avatar is not a photon, so how could my avatar possibly escape from a black hole?
 
@DavidCarlisle I heard you are to blame that marginnote no longer works in lists ;-).
 
@UlrikeFischer ?
@marmot you are supposed to be the expert in tunneling, you work it out.
 
@DavidCarlisle someone suggested to add \@parboxrestore ... and this is the result:
\documentclass{article}
\usepackage{marginnote}
\usepackage{lipsum}

\begin{document}

\begin{itemize}
\item abc \marginnote{test}\lipsum*[1]  % too high
\end{itemize}

\end{document}
 
@DavidCarlisle I guess that if you could prove that the Hawking radiation contains marmot avatars, you could make a major contribution to the solution of the information paradox. I'm listening. ;-)
 
9:19 PM
@UlrikeFischer hmm not in the mood to trace this week, (although I see it changed) is it just parboxrestore? \everypar weirdmess?
 
@DavidCarlisle I didn't really tried to trace it, I wasn't in the mood either, but it works again if one use the option noparboxrestore which restores the old behaviour. I already told Markus. He will look at it when back.
 
@UlrikeFischer OK I'll look next week
 
9:37 PM
@DavidCarlisle but only after the utf8 question. Not that I understood what it was about but it sounded like a bug ;-).
 
@UlrikeFischer which utf8 q?
 
@DavidCarlisle the pull requests github.com/latex3/latex2e/pulls,
 
@UlrikeFischer ah yes those that is a feature, yes.
@UlrikeFischer you've got mail
