quack

@DavidCarlisle oh no

baa!

@JosephWright Did something change in l3build? I don't think any directory names of beamer changed, did they?

@samcarter_preparing_for_xmas Yes, something in l3build I think: I was busy over the weekend but should manage to work around it today for a beamer release, then can try to fix properly

@Plergux quack <3

@PauloCereda kid was cleaning up his room yesterday and found this...

@PauloCereda This is getting suspicious :p

@Plergux OOH

@Plergux Lovely

@samcarter_preparing_for_xmas Ah, got it: Windows vs Unix issue

@JosephWright That's easy to solve: ask @PauloCereda for help for installing Fedora :)

@samcarter_preparing_for_xmas ooh <3

@JosephWright welcome to the party

@samcarter_preparing_for_xmas Er, other way around: works on Windows, not elsewhere

@JosephWright Works on windows? That's something one does not hear often!

@JosephWright this is a bug, not a feature. :)

@samcarter_preparing_for_xmas I must have some pattern wrong somewhere

@UlrikeFischer I'm almost there with the color stack business: just trying to work out how to get the 'right' results for page changes

@JosephWright what do you mean? When do you get wrong results?

@UlrikeFischer I have a mail for you :)

@UlrikeFischer I'd got my test file wrong, from debugging: it's all now working as-expected

@samcarter_preparing_for_xmas beamer is out: I think I should get CTAN to update the authors (you and me nowadays?)

@PauloCereda github.com/pgf-tikz/pgf/issues/954

:56425325 Exactly what I thought :)

@JosephWright done. :)

@JosephWright it's consistent. :)

@PauloCereda Yup

@JosephWright the "beamer support group"?

@UlrikeFischer Hmm, could be: haven't seen Louis for over a year, looking at the log

@JosephWright That's great news! Thanks for building the new release! About the authors: Please feel free to add me. Do you have any contact with L. to see if he is still in the game?

@samcarter_preparing_for_xmas I've heard nothing :(

@samcarter_preparing_for_xmas Let me know by mail how you want to appear (unless of course it's just as 'samcarter')

@JosephWright ooh

Stop the presses

@CarLaTeX, @egreg ^^

@PauloCereda :)

@JosephWright as samcarter, that's my ctan profile ctan.org/author/samcarter

@samcarter_preparing_for_xmas Ah, great

@PauloCereda That's the Right Thing To Do! ;-)

@Rmano :)

@PauloCereda This should be international law!

@egreg :)

Google Mail is down! :)

@PauloCereda ? Not here...

@Rmano It's down for us...

Well, not down in the strict sense, but login issues. :)

@Rmano tis down here too

@Rmano gmail drive, youtube, ...

twitter.com/…

@DavidCarlisle ooh we can procrastinate

I mean oh no

@PauloCereda or work

@DavidCarlisle oh no

Hmmm ... would be a nice idea to add in the notice on filecontents package documentation where to find the new docs? I suppose it's in source2e...

@Rmano Mostly ltnews30, I think

@PauloCereda oh well, I'll just have banana instead. :p

@Plergux ooh pointed stick

@DavidCarlisle yep, also here now. Several please login windows around. This morning Moodle exploded, too... in the middle of an exam...

@Rmano everyone has latex.ltx in their emacs don't they?

@DavidCarlisle of course (just looking for the name of the overwrite flag, which results to be surprisingly overwrite)

@DavidCarlisle what's emacs?

OH NO IT'S WORKING AGAIN

@PauloCereda Advanced nano: github.com/rougier/nano-emacs ;)

@PauloCereda it's not the PDF reader that comes up when you say texdoc source2e

@DavidCarlisle, @UlrikeFischer Panic over with page number colour: I'd missed a few lines of color.sty

@TeXnician ooh

@samcarter_preparing_for_xmas ctan.org/pkg/beamer

@PauloCereda like vim, but usable.

@JosephWright that's panic on a high level, I constantly get errors because I forget the #1 #2 for :Npn-definitions.

@UlrikeFischer :)

@DavidCarlisle you are mean

@JosephWright yeah!

@JosephWright that's because colour is misspelt

@PauloCereda but I can write a color package without lines missing

@DavidCarlisle ooh

@PauloCereda lol

@DavidCarlisle a package with no lines has no lines missing, it sounds mathematically correct. :)

@PauloCereda that almost describes indentfirst

@Rmano Had the same problem recently chat.stackexchange.com/transcript/41?m=56334228#56334228 :)

@PauloCereda heh heh heh.... any thing in the universe can be connected to Monty Python. :p

@Plergux ooh Notlob

@PauloCereda "I'm sorry, I have a cold." :p

@Plergux a pet halibut

@PauloCereda You're a looney!

@Plergux ooh let's spot them

@PauloCereda Whoops, that was not a looney. It was a "televison personality" :p

@Plergux LOL

@JosephWright you broke beamer?

@PauloCereda ?

@UlrikeFischer Someone in the TL list. :)

@PauloCereda oh "not found". And no info about which tex system is used ...

@UlrikeFischer Crystal ball, it was easier to assume @DavidCarlisle @JosephWright broke it. :)

@PauloCereda ??

@JosephWright see texlive list

@DavidCarlisle I only updated it this morning ...

@JosephWright you are a timelord, so it could mean yesterday. :)

Interesting how some people delete their questions when you inform them that as long as their MWE contains information we do not have access to we cannot help. Especially when you're using both a custom class and tex file, that is not provided.

@daleif Oh great

@daleif (sitting here, just hoping it's none of the relatively few people using unpublished templates of mine)

It was using UPMThesis.

@daleif puh, not my fault :)

@Skillmon ooh rabbits <3

Hi, see this question: tex.stackexchange.com/q/574974/4736 . It is about having multicols with different widths. This is a quite frequent question. The answers and packages (at least their concepts) all are from pre-LuaTeX age. As far as I understood LuaTeX, we can tamper with some internals of TeX. Or are the new hooks of LaTeX3 a good starting point for enhancing the multicol package? -- Before you ask, sorry, I'm only a user...

@KeksDose doing that with automatic page breaking is hard even with luatex. It really isn't the tex way.

@DavidCarlisle I remember a speech at either at the TUG meeting in Darmstadt 2015 or a Dante meeting around that time, a description of the use of LuaTex were such cases: why do columns have to run vertically? landscape, two columns of random width and running in an 45° angle over all pages. Hm, okay, where to place the footnotes, then. But merely some columns of different width and no special treatment for footnotes? However, if you say, it is difficult, I better forget about it.

@KeksDose positioning the columns anywhere at any angle is easy, but changing the width mid-pararaph means setting a \parshape before the paragraph starts that specifies so many lines at the first width and then the remainder of lines at the new width, so you need some multi-pass algorithm that detects which paragraphs occur at places where the line width changes. ...

''' That isn't impossible, but combining that with multicol's multi-pass algorithm to determine where to break the columns to balance the column length doesn't make it any easier.

Hi all, and especially L3 experts. How do I invoke the firstaid fix for my pgfmorepages.sty package? I can see on my system that the relevant file is there (latex2e-first-aid-for-external-files.ltx) and it has the fix for the package in it, but it doesn't seem to be being invoked when I run a simple test file.

@AndrewStacey hi!

@AndrewStacey you shouldn't need to do anything, firstaid is loaded automatically. Can you show an example that doesn't work?

@UlrikeFischer That was what I'd thought should happen, but then I got this issue opened github.com/loopspace/pgfmorepages/issues/5 and after updating TL today then I still get the undefined error. MWE in next comment.

\documentclass{article}
\usepackage{pgfmorepages}
\usepackage{lipsum}

\begin{document}

\lipsum[1-4]{}

\end{document}

This causes an undefined command error in all engines (pdflatex, xelatex, lualatex)

Oh, hang on. I have an idea as to what the problem is. You've just copied the pgfpages fix into the pgfmorepages one. They call \pgfhookintoshipout at slightly different times. pgfpages calls it at the end of the package whereas pgfmorepages calls it via an AtBeginDocument hook. So when your firstaid patch gets run then \pgfpages@originalshipout isn't defined and thus \shipout gets set to undefined. So I think that you need to remove the first line from your hook.

Dammit, time for something I've been wanting a long time but never taken time to learn. Got to go into the pgfplots manual and figure out how to put in peak labels with a title OTHER then their x-value

Oh that looks simple

@AndrewStacey yes, but I don't get an error if I run latex-dev and I don't know why ;-(.

@AndrewStacey at best open an issue in the latex github.

@UlrikeFischer Will do. I'll post this there, but for the record here as well then I get that the hook should be:

\AddToHook{file/after/pgfmorepages.sty}[firstaid]{%
  \cs_set_nopar:Npn \pgfhookintoshipout {
    \cs_set_eq:NN \pgfpages@originalshipout \tex_shipout:D
    \cs_set_eq:NN \tex_shipout:D \pgfpages@interceptshipout
  }
}

@StefanKottwitz Hi, very kind Stefen I had to use the translator as usual. Sorry I don't know English as well as you do. There are certain expressions that I do not fully understand. I have understood your reasoning and will try to be much more careful and to flag better the answers or questions that are misleading, incomplete, or meaningless. Best regards and good work. Thank you and no apologies whatsoever. You are doing your job professionally. Best regards.

Good evening to each user...All the best. Sebastiano

@Sebastiano Hi Sebastiano!

@Sebastiano By the way, a flag cannot replace a comment. For example, when there are 3 flags on an answer (low quality, bit offtopic, not good practice) but nobody commented, what shall moderators do? Typing the comments? There are not many options (deleting or keeping), the other options (commenting, voting, editing and suggesting an edit) are done by us fellow users.

Of cause it's good to raise awareness.

And yes, commenting may lead to a backlash, so it's a free own decision anyway.

@StefanKottwitz I have understood what you have written. Certainly being a moderator is not a very simple role. It requires the right equilibrium and the knowledge to read the mind of the users. Even if I am connected I am preparing tomorrow's lesson :-)... Today Google crashed and I anticipate the work for tomorrow and the following days. A hug and always great.

@Sebastiano Just talking :-)

@Sebastiano Ooh, Equilibrium and Minority Report, good movies :-D

@Sebastiano After Corona months, 2020 is in the endgame, adding google&youtube crashing, how can this be topped.

Not to mention the lockdowns. (big one in Germany now)

@StefanKottwitz Ahahaha are you having fun? :-) This 2020 has given me bad news...I'm really hoping for something good to come from Father Christmas or the Epiphany. :-)

@AndrewStacey @UlrikeFischer but the answer shouldn't really be that first-aid gets fixed, should it? yes temporarily that is what we would do to help out, but first aid is to temporarily fix issues not to fix them for good. I'll expect to take all of them out by next release.

@StefanKottwitz And I hope there will be lots of nice surprises. I don't want the bad ones ahahah.

@FrankMittelbach but we explicitly took these patches in, until real configuration point for the shipout exists.

@UlrikeFischer oh well, yes you are right those are the two packages that dive deep :-( ... ok then the release after .-) ... so sure then a fix fix to first aid it is for now.

@AndrewStacey @UlrikeFischer can of worms: to test it one needs to load it into the test suite (should have thought about that) but that then needs pgfcore which, surprise, isn't called that for loading , so ... slowly getting there I guess
