$\mathbf{x^{*}}$

is the above wrong?

Command \textbackslash invalid in math mode

the error it shows

Today I started learning to use minted and I eventually had to create a symlink to pygmentize as described in tex.stackexchange.com/a/281188/218142 in order to build my document. pygmentize is installed as part of my Anaconda distribution. Do all TeXShop users have to do this or is there something set incorrectly somewhere on my system?

And shouldn't the symlink point to /usr/local/texlive/2021/bin/universal-darwin instead?

@LaTeXereXeTaL Ah, yes, I think you do need to do that

@LaTeXereXeTaL macOS doesn't add the PATH for GUI applications, so TeXshop (and others) have to 'manually' add things. It knows about /Library/TeX/texbin/, so that gets added, but other places ... less so

@LaTeXereXeTaL On the positive side, I've now set up Pygments :)

Anyone else seeing

! Undefined control sequence.

when trying to use minted?

For a simple example (from the manual):

@JosephWright No. Your example works fine here (Linux, TL2021 fully updated).

@TeXnician What version of Pygments do you have?

I get

joseph@palladium texbin % pygmentize -V
Pygments version 2.9.0, (c) 2006-2021 by Georg Brandl, Matthäus Chajdas and contributors.

@JosephWright I get the same.

@TeXnician Hmm, must have been a stray file: I've cleaned up my test area and the issue has gone. Thanks

@barbarabeeton It must be those pesky rich people. I hear they do well of other people's work.

of -> off

@MarcelKrüger What happened with GitHub Action and releases?

@barbarabeeton @PauloCereda ^^ Dress rehearsal for the TUG Conference

@JosephWright Oh I forgot to write you. luaotfload has a working setup for it now, but it currently requires the list of installed TeX Live packages to be duplicated. That seems bad, especially since I'm thinking about a smaller caching improvement which would end up with a third copy of the package list, so I want to move the list into another file instead. So the setup in luaotfload dev works, but it will be improved further after the TUG conference.

@MarcelKrüger Ah, right: I'll stick with the standard GH Actions one for the present, then

@JosephWright is there already an interface in expl3 to set the \escapechar?

@Skillmon No: I think if we can avoid that, we will

@JosephWright then I'll use it directly (have a loop which does branching based on string representation, so I'll need \tl_to_str:n to yield the "correct" escape char).

@Skillmon I guess one for LaTeX-L? The aim, more or less, has been to not expose \escapechar

@JosephWright well, life would be better if no one ever mangles with it, but unfortunately that's not guaranteed.

@JosephWright I don't think it needs to be in expl3.

@UlrikeFischer Building l3backend for CTAN

@JosephWright oh, I forgot, I wanted to run the pdfresources tests with it, doing it now.

@UlrikeFischer Ah, cool

@JosephWright but it looks ok. 2/3 are through without problems.

@JosephWright I think I know how one could allow arbitrary tokens inside \__tl_act:NNNn (it currently depends on an end marker), but the performance would be worse than it currently is... Yay or nay?

@Skillmon I think Yay: ideally we want minimal restrictions on tokens, even if they cost us a little

@Skillmon Same as the argument for having TF safe against \fi, etc.: there is a cost but it means you don't have to worry about special cases

@JosephWright will have to test things, will make heavy use of \if_false: { \fi: and \if_false: } \fi: :)

@Skillmon I'd say it's fine: the tl_act mechanism is already not that fast, and it's meant for cases where it's more important to have close control than to hit maximum performance

@MarcelKrüger Hmm, something not right using the 'vanilla' release system :) github.com/josephwright/siunitx/runs/…

@JosephWright Not sure what makes it more standard than the others, especially since it isn't listed on github.com/actions/create-release, but it doesn't support wildcards...

@MarcelKrüger I think it's the one you mentioned ;)

@MarcelKrüger Ah, that would be an issue

@MarcelKrüger I'll wait for you to sort stuff, then

@UlrikeFischer Beethoven is taking notes?

@samcarter_looks_forward_TUG'21 I think his name is Beethoven, but all here call him "Der Sekretär" ;-). He is very eager to record everything.

@JosephWright @samcarter_looks_forward_TUG'21 you saw that they changed the shedule?

@UlrikeFischer No??

Is anyone around who uses texlive from a linux package manager? I'm trying to bring the install instructions in the beamer user guide a bit more up to date and am wondering if someone could check of these new instructions are correct: github.com/samcarter/beamer/commit/…

@JosephWright the times changed in part. I'm now at midday, and Frank interview is saturday evening. Not sure what else all changed.

@MarcelKrüger I'll stick to building locally until this settles down, then :)

@UlrikeFischer Tomorrow also changed. I think there was a tour, now on needs to know Spanish or Portuguese ....

@UlrikeFischer Nice job for Beethoven, keeps him busy :)

@UlrikeFischer Maybe he can help with the transcription of the interviews?

@UlrikeFischer Hmm, tricky

@JosephWright Why?

@UlrikeFischer I've been moved a bit earlier, I think: I was already a bit worried about whether I can be around for questions. I'll see what I can do

@JosephWright threatening @DavidCarlisle?

@UlrikeFischer No :)

@UlrikeFischer In other news, I've sent the update to CTAN (plus siunitx to keep Frank and @samcarter_looks_forward_TUG'21 happy)

/me putting the cake in the fridge so it is nice and cool when the party starts :)

@samcarter_looks_forward_TUG'21 I can cheat, add a small API improvement and call it 3.1 ;)

@JosephWright no cake for you in this case :)

@samcarter_looks_forward_TUG'21 I have a load of requests, I will have to decide when to start on them

@JosephWright this shows how useful the package is for users!

@UlrikeFischer ooh

@UlrikeFischer -- love the hairdo!

@barbarabeeton and remark the well placed tex lion ...

Why use the latex tag if this is the one tool they absolutely don't want? academia.stackexchange.com/questions/172987/…

@samcarter_looks_forward_TUG'21 People are strange

@CarLaTeX yeah.

@samcarter_looks_forward_TUG'21 Weird: for most people, LaTeX comes down the list, even if they are routine LaTeX users (I've always meant to learn Illustrator ...)

@JosephWright Microsoft Paint is good for an academic conference poster, provided that the poster has a prominent statement that it's done using a Microsoft product.

@JosephWright It's working perfectly for me now too.

@samcarter_looks_forward_TUG'21 Weird question. What's wrong with Beamer?

I've used it. It's not "cumbersome".

Terrifying as some aspects of TeX can be, simple end user stuff shouldn't be something to run away from.

Though last I heard Beamer was orphaned, along with Till Tantau's other stuff. Not currently a user, though.

@JosephWright Down the list, meaning low in preference?

@FaheemMitha it doesn't produce posters.

@UlrikeFischer Oh. I thought it did. I guess I was mistaken.

I thought I created a poster with it once.

@FaheemMitha well perhaps you should check the status. The current maintainer are samcarter and Joseph.

@UlrikeFischer Oh.

There's something called beamerposter. Maybe that's what I was thinking of.

@UlrikeFischer mmm, then I need to use a time machine and use something else for my previously with beamer produces posters :)

@FaheemMitha Yes

@FaheemMitha no idea :) I presume it depends on what the content is, but for my poster, which were mostly images of plots, some headline and some bit of text, beamer worked nicely as it made using columns easy.

@JosephWright I guess if I would not use beamer, I would inkscape as the next best thing.

@samcarter_looks_forward_TUG'21 well you always can tweak things ;-). But it is not meant for it.

@UlrikeFischer It might not be meant for it, but compared to other latex classes I think it rather well suited. No automatic page breaks is good for a one page document and head- and footline without margins allows for the most commonly used poster designs.

I'm currently testing variable fonts for luaotfload and got this pages of pretty much all weight variants of Source Serif Variable. There's a certain beauty to how the text fades in over the page, I'm somewhat tempted to write an automated solution to add something like that to ordinary documents.

@MarcelKrüger wow. Is that with the harfbuzz or with the node renderer?

@UlrikeFischer HarfBuzz. There it took (with fonts cached) about 10 Minutes to build, the node renderer needed 20 Minutes for only half as many fonts (which HarfBuzz compiled in 3 Minutes), so I didn't even try it. (The image has 1401 font variants)
