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 \typeoutfontenc cries out because they are not setup for use in LaTeX.
@Skillmon inputenc not fontenc but \typeout{\detokenize{...}} probably works. (but you may need -8bit to stop pdftex showing control character in ^^A notation
@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).
@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:-)
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?
@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 :-)
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? π
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.
@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
@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 ...
@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?
@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 ...
@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)
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....
@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.
@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. ;-)
@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.
