@JosephWright Nice!

@CarLaTeX get 500 more and I'll forgive you the misplaced comma

Finally.

@AlexG where is the comma so that we can complain about it??

@UlrikeFischer It got lost somehow ;)

@JosephWright vvvvv

@AlexG get 3840 more and I'll forgive you the missing comma

@JosephWright If you want to easily test our pre-release, arara (the cool TeX automation tool) offers a handy directive option: Just include branch: developer in your favourite engine and that's it: you are running our pre-release!

We ducks are very good at testing kernels. :)

@samcarter ooh twitter.com/markarayner/status/1575119491897475072

152 seconds down form 160 seconds for pdflatex-dev compilation. Could be into the noise, but...

TEXINPUTS=../tex/: pdflatex circuitikzmanual.tex  160.58s user 1.14s system 99% cpu 2:41.91 total
TEXINPUTS=../tex/: pdflatex-dev circuitikzmanual.tex  152.01s user 1.21s system 99% cpu 2:33.39 total

@Rmano ooh squirrels are very good at noise detection. :)

@Rmano delete the tikz and use picture mode it will be down to 2s

@PauloCereda :P

@DavidCarlisle why have documentation in the first place? :)

@PauloCereda timing tests?

@DavidCarlisle ooh

@DavidCarlisle I'll work for it

zooooooooooooom

@PauloCereda we should put a bit fire into the discussion by asking if it it better to use jitsi on windows and share an emacs screen or to use zoom on linux with vim.

@UlrikeFischer ooh

@PauloCereda everyone could use microsoft teams

@DavidCarlisle oh no

@PauloCereda my life is in Teams post covid

@DavidCarlisle oh my

@DavidCarlisle Doesn't Teams basically kill PCs if too many people has their camera turned on at once?

@daleif i thought that was mostly the case for macs.

@daleif well, it's a bit better now, at least the linux version. Nicer in winter, you have an excuse to have the room at an higher temperature than the government-imposed 19 ºC

@daleif on my windows laptop, teams is slow even without any meeting running ... so sad

@Rmano There is also a fridge in my office, that helps on the temp.

@JasperHabicht Interesting It does not seem that slow on my Linux, granted it uses a heck of a lot of RAM

\ducksay fails if used inside a tabular :(

@Skillmon The duck wants to be released from the barring table...

@mickep :) No, I rather suspect some strange bug. Just not yet sure whether in ducksay or in expl3.

@Skillmon this here works:

\documentclass{article}
\usepackage{ducksay}
\begin{document}

\begin{tabular}{l}
\baselineskip\normalbaselineskip
\ducksay{blub}
\end{tabular}
\end{document}

@UlrikeFischer yep, that's the issue :(

@UlrikeFischer thank you for taking a look (and of course, beating me in finding the culprit)

@Skillmon but I don't know yet where it is actually used.

@UlrikeFischer in calculating the necessary box delimiters for the speech bubble.

Inside of \ducksay_shipout: (which should probably be \__ducksay_shipout:, ducksay is a mess, basically every expl3-function should be internal)

@Skillmon ah, I hadn't seen that some code is in another file.

        \int_set:Nn \l_ducksay_msg_height_int
          {
            \int_max:nn
              {
                \fp_eval:n
                  {
                    ceil
                      (
                        (
                          \box_ht:N \l_ducksay_msg_box
                          + \box_dp:N \l_ducksay_msg_box
                        )
                        / ( \arraystretch * \baselineskip )
                      )
                  }
                + \l_ducksay_vpad_int

@UlrikeFischer yep, part of the home-brew rollback (before the rollback support was added to LaTeX -- or at least before I knew about it)

Guess I need to use \normalbaselineskip throughout ducksay, or at least if \baselineskip is 0pt.

@Skillmon yes. And I agree that it is a bit of a pain, that it is zero in a tabular, I got bitten by it too.

@UlrikeFischer do you know if \normalbaselineskip is always up to date, or should I prefer something like \ifdim\baselineskip=\z@\normalbaselineskip\else\baselineskip\fi?

@Skillmon it is set in \set@fontsize so every font size change, whether that is every place you consider an update needed depends

@Skillmon \normalbaselineskip is imho more reliable if you want "the normal baselineskip".

@Skillmon \normalbaselines will set lineskip as well

@DavidCarlisle well, let me rephrase: Is there any place in which \baselineskip gives the correct result while \normalbaselineskip doesn't?

But I guess not, so I'll simply use \normalbaselineskip.

@Skillmon define "correct" If the user has gone \setlength\baselineskip{3in} just before the table, do you want 3in or \normalbaselineskip which is say 15pt

indentfirst ? tex.stackexchange.com/questions/659993/…

@DavidCarlisle well, if he did that just before the table then inside the tabular \baselineskip would be reset to 0pt, so \normalbaselineskip is the best bet here... But I guess I'll use the \ifdim approach to use \baselineskip as much as possible...

@DavidCarlisle certainly. And expkv so that he can never write normal code again!

Just realised that while nesting dimension registers into \fpeval one can't directly nest \dimexpr and has to use \the\dimexpr...

@DavidCarlisle ooh

If I listen to Rosamunde long enough, can I be German? :)

@barbarabeeton still using tex.ac but we lost the uk, you know

@StefanKottwitz -- The "formula" I have is "texfaq,org/FAQ-xxx". Are you saying that it's something else?

@StefanKottwitz brexit strikes again

@PauloCereda German, Italian, Brazilian, English --- you are hoarding nationalities!

@Rmano no one will have him

@StefanKottwitz -- Thanks for updating lots of other links. I only tackled the ones I'm familiar with. (I think there should probably be a French entry, but didn't have enough energy to dig.)

@barbarabeeton it will be something else, texfaq.org ist the standard

@barbarabeeton I added the French forum

@StefanKottwitz -- Great! Thanks.

I read in the TeXbook today that in the exercises environments that are found along the book, an instruction that "prohibit[s] beginning a new page just after that line". Anyone knows what this command is? It is written on page 10.

@tush \endinput

@StefanKottwitz I want to avoid page breaks inside some thmtools environments. Do you think that this command can be helpful?

It prevents beginning a new page... ;-) more seriously, a LaTeX way may be \nopagebreak[4] or the needspace package

@DavidCarlisle tex.stackexchange.com/questions/660029/…

@JosephWright ?

I'm getting tired just watching @DavidCarlisle's edits appear in real time. (six in the time it took to write that sentence)

@LaTeXereXeTaL just experimenting

@DavidCarlisle I thought it might have been a bot.

@LaTeXereXeTaL well a bot assisted human

BTW, I was recently asked to assess some edits for quality and had to skip them because I wasn't at all familiar with the subject matter and had no basis for assessing the edits.

@LaTeXereXeTaL this is a mechanical edit changing the url of the tex faq from one that doesn't work to one that does

@DavidCarlisle Ahh interesting. I assumed it was mechanical or automated somehow based on the speed.

@DavidCarlisle -- And one of the reasons I was doing it by hand was to avoid burying the "active" list ...
