This might be a dumb question, but is the keepaspectratio option redundant for \includegraphics if no other option is passed? I.e. in:

\includegraphics[keepaspectratio]{filename}

is keepaspectratio redundant?

@DavidCarlisle XML? Wasn't that the compromise between human readable and machine readable by making it inaccessible to both?

@Skillmon I work on xml documents every day, and I believe I'm human.

@FaheemMitha yes you have to specify both width and height before it does anything

hi, what is the font used in the TeX/ LaTeX typography?

@EnthusiasticEngineer texlive comes with several thousand fonts, and xetex and luatex can use any font installed on your system in addition to the ones that come with texlive.

@DavidCarlisle thank you, and what is the name of the font in its logo... is it serif series?

@EnthusiasticEngineer it uses the current font it isn't a graphic logo if you select a font then \LaTeX uses that font, just shifts the letters a bit.

@EnthusiasticEngineer : \DeclareRobustCommand\TeX{T\kern-.1667em\lower.5ex\hbox{E}\kern-.125emX\@}

@DavidCarlisle thank you :)

@DavidCarlisle Ok.

@EnthusiasticEngineer the default font is Computer Modern Roman.

@Skillmon very nice font, I love it

I wish I could write a LaTeX package like the ones on CTAN (even a small one), but I don't have enough knowledge on it...

The stupid hats are back :(

@DavidCarlisle oh no

@PauloCereda you already have a stupid blue hat

@DavidCarlisle oh /cries

@DavidCarlisle I haven't earned any hats yet :( /cries

@DavidCarlisle I got one already too - probably for something I did nearly 12 month ago

@UlrikeFischer apparently I have posted a starred chat message within 12 hours of the start of 2020 UTC time which seems quite impressive given the date.

@DavidCarlisle yes, I got this too. Either they can look into the future or someone forgot to adapt the date in the code ...

@UlrikeFischer did you like the "I have used two of David Carlisle's packages and things don't work (ps I have completely broken a core latex command at the same time, but I won't mention that)" question?

@DavidCarlisle which one?

@UlrikeFischer the longtable/landscape/\clearpage one (you left a comment)

@DavidCarlisle ;-) I was still on my smartphone in the morning and couldn't really test what this clearpage command is meant to do and so commented only on the empty pagestyle. But I always wonder how this "I'm new to latex" people get hold of such code.

@UlrikeFischer By copypasta, I presume. How else?

@HaraldHanche-Olsen but why aren't they scared stiff when seeing this code with all the \if and @?

@UlrikeFischer They probably are scared stiff. So much so, that they don't dare question it and much less remove it, thinking it must be important since someone put it there.

I don't remove parts from my car either, even if I don't know what they're for.

@HaraldHanche-Olsen ;-) .

@HaraldHanche-Olsen but if a passing stranger passes you a ticking package and suggests you strap it to the engine, would you trust them implicitly and do as suggested?

Friends, I published a Twitter poll here twitter.com/paulocereda/status/1203989046374096896 but I would be very grateful to hear your opinions as well, if possible.

Would you favour a command line application like arara to have localised messages (i.e, speak your language) or do you prefer using English as default?

[ ] Yes, localised messages
[ ] No, English is enough

@PauloCereda hehe 100% agreement with me

@daleif Thank you! :)

@DavidCarlisle Not here! (Disabled immediately)

@JosephWright they have taken my hat away :)

@PauloCereda Não entendo a pergunta como está em inglês.

@DavidCarlisle oh

That ingenious OS called Windows. Today: Connecting a second monitor, but it is only recognized as long as the monitor is turned off, as soon as I turn it on, Windows doesn't find it anymore :(

@PauloCereda I tried to set the tick, but it didn't work in this chat, and Twitter tries to sell me an account for my vote to suffice. So here is my vote including reasoning: No, English is enough, localised messages only help for people who have no glimpse of English and aggravate scripting and helping.

@DavidCarlisle No, but that's a bad analogy. This person probably got the code from a friend who got it from a friend who … (you get the drift), and who wouldn't want to trust their friends?

@DavidCarlisle so obviously it's your fault.

@Skillmon Thank you very much, mr. rabbit! :)

@PauloCereda well personally I don't need localised messages and english messages are better for asking help or when searching in the documentation or in the internet. On the other side I wouldn't like to miss some of the arara localisations, and localizations can be helpful for people who don't understand any english.

@UlrikeFischer Fair point, thank you! :)

@UlrikeFischer was it intentional to once use the British English spelling and once the American for the word localisation/localization?

@Skillmon I'm trying to be readable on both sides of the atlantic.

@UlrikeFischer <3

@Skillmon ooh

@barbarabeeton twitter.com/DickKingSmith/status/1203738476027482117

@PauloCereda Ohh, you have a new favourite on twitter, don't you! :)

@mickep :D

@PauloCereda -- Tee hee! Love that punk haircut! Little ones haven't got it yet.

@barbarabeeton <3

@Lupino no interface to it but you can do \makeatletter\setlength\@mathmargin{3cm}\makeatother ... \makeatletter\setlength\@mathmargin{1cm}\makeatother to have different indents

@DavidCarlisle thanks, i found \mathindent=6mm\relax but this is universal for both numbered and unnumbered equations. customer wants unnumbered equations woth no indention, and numbered with 6mm margin… I tell them, its not possible, right?

@Lupino mathindent isn't consulted after the preamble (it just sets \@mathmargin) but as I say you can set \@mathmargin locally to get different settings but you would have to switch manually the indent between unnumbered and numbered forms

@DavidCarlisle i'm writing a cls, so i'm always in the preamble ;) i found a way by redefining \mathdisplay and utilizing \ifst@rred…\fi that works. So far.

...only for equation, not for align. dangit.

@Lupino align* is as below so you should be able to patch \start@align

\newenvironment{align*}{%
  \start@align\@ne\st@rredtrue\m@ne
}{%
  \endalign
}

@DavidCarlisle i found that too. is there a single macro one could patch that covers all displayed equations?

@Lupino not really \start@align, \start@gather etc are most obvious places. You'd have to be careful about not breaking mathtools versions as well

@DavidCarlisle thanks so far :) i think i will deny the request; too dangerous for such a minor issue.

@DavidCarlisle btw, are you still maintaining xmltex?

@Lupino define "maintaining" :-)

@DavidCarlisle that's easy: if it's broken, it's your fault

@HaraldHanche-Olsen I'm reliably informed it's never his fault.

@FaheemMitha for xmltex, that is certainly true.

Thank goodness for AppleCare...

@AlanMunn Oh dear

@AlanMunn ops

@AlanMunn what did you do to it?

@UlrikeFischer @JosephWright @HenriMenke possibly final slices of dragon for a while alphalph askinclude bitset catchfile listingsutf8 pdfescape picture selinput

@DavidCarlisle Yay!

@DavidCarlisle no more steaks?

@JosephWright it was nice to be able to address the epstopdf issue from the texlive list in 5 minutes, and not have to spend an hour and a half repackaging the whole lot:-)

@DavidCarlisle Yup :)

@DavidCarlisle Dropped it. But I now have a brand new replacement for $50.00. And I can do this again one more time before 2021. :)

@PauloCereda Just received your season's greetings - thank you! <3 I sent you something a while ago, but I don't suppose you'll get it for a year or so, knowing the postal service to Brazil. P.S. I also got a colleague to translate the Portuguese for me. ;)

@MarcelKrüger pdf and log sent ...

Does \let\foo\@undefined really free some of TeX's memory?

@Skillmon Memory usage is exactly the same with and without the re-definition (according to tex's log files).
