Happy new year!

But I am still in 2018. :)

marmot

@PauloCereda Oh no! (Me too ;-)

Paulo Cereda

@marmot ooh

marmot

@PauloCereda I guess you will be faster in 2019. Which is not so bad. But being scooped by @DavidCarlisle and @egreg is a rather strange feeling. Luckily it does not happen often. ;-)

Paulo Cereda

@marmot :)

David Carlisle

Happy new year (GMT:-)

Ulrike Fischer

@DavidCarlisle no picture mode fireworks?

marmot

@DavidCarlisle Why only Geese, Marmots and Turtles (GMT)?

@JosephWright Congrats!

Joseph Wright

@PauloCereda :)

@PauloCereda Seemed like a good time for a post

Paulo Cereda

@JosephWright no duck reference, I am sad. :)

Ooh, @MartinScharrer is here :)

Paulo Cereda

ooh

@JosephWright we ducks say ooh a lot :)

Martin Scharrer

@JosephWright Hi

Happy New Year To You All!

Paulo Cereda

13:01

@MartinScharrer Joseph is a very tall duck, I met him. :)

@MartinScharrer Happy new year, pal!

Martin Scharrer

@PauloCereda Thanks, you too, pal!

Paulo Cereda

@MartinScharrer plans for this year? :)

@marmot, @UlrikeFischer, @samcarter: one for you in TikZ: github.com/anvaka/atree :)

@PauloCereda A very stylish tikz Xmas tree! Just a duck is missing at the top :)

egreg

14:21

@PauloCereda Most interesting is the Honda next to the car. ;-)

marmot

15:01

@PauloCereda I guess it is not too difficult to draw something very similar with TikZ or pgfplots. At least this one was straightforward.

@JosephWright @MartinScharrer Happy New Year! Could any of you please remove the last three comments under this post?

Joseph Wright

@marmot Done: best in future to simply flag

marmot

@JosephWright Thanks! Will do.

@CarLaTeX Do you want to answer this one? It has a \pizza macro in it?

AndréC

15:38

@JosephWright Why did you delete these comments, which were in no way aggressive in these post? tex.meta.stackexchange.com/questions/7998/…

CarLaTeX

15:55

@marmot lol! I leave it to you, too difficult to me :)

marmot

@CarLaTeX It's not difficult. Answer: "Add \usetikzlibrary{positioning} and real pizze can be eaten by TeX and LaTeX users alike." ;-)

CarLaTeX

@marmot You already answered in comment, and I see the OP asked if he should delete the question… Let's save pizzas for other dinner occasions :)

marmot

@CarLaTeX OK. (I actually feel that what the OP achieved is a more flexible version of pgf-pie, so I don't think it is useless. But I am not sure.) Are these winter tires on your car? ;-)

CarLaTeX

@marmot Yes, new year's tires :)

marmot

@CarLaTeX And they look odd because 2019 is odd? ;-)

CarLaTeX

16:10

@marmot Is it odd because it contains a 9 (ask @egreg)?

marmot

@CarLaTeX Didn't now 92 is odd but if you say so. ;-)

CarLaTeX

@marmot I think only a final 9 is a problem...

marmot

@CarLaTeX 19-9 isn't odd either.

CarLaTeX

@marmot Only a final 9 in the year...

marmot

@CarLaTeX That's odd.

CarLaTeX

16:17

@marmot I mean odd in the sense of strange, not in the sense of the contrary of even

marmot

@CarLaTeX As long as you do not put pineapple on your pizza, which is a really odd thing to do, you will be fine.

CarLaTeX

@marmot You don't have to worry about that :)

David Carlisle

@marmot you can't put pineapple on pizza as it isn't really pizza until it has pineapple

Vrouvrou

hello, how to reduce the space between the chapter the section and the text in latex ?

Skillmon

@Vrouvrou This depends heavily on the used class and packages. You should ask a question on the main site with a complete MWE.

@Vrouvrou If you're using one of the KOMA classes there are options built in to control those spaces. If you're using the standard classes you could load for example titlesec and customize them with that package.

@Vrouvrou memoir most likely has a built in mechanism to change those, too, but I don't know for sure.

Harald Hanche-Olsen

16:34

@marmot 2019 is even in base 11.

2

marmot

@HaraldHanche-Olsen Good point. So 2019 is not necessarily odd!

boycott.se - yo'

17:19

@HaraldHanche-Olsen that's sort-of a wrong understanding of the notion "even"

David Carlisle

‮9102 ‭@boycott.se-yo' but this is even

Ulrike Fischer

17:46

@DavidCarlisle which output would you expect here:

\documentclass{article}
\begin{document}
\prehyphenchar = 100

{ \prehyphenchar= 200 }

\showthe\prehyphenchar

\end{document}

with lualatex

David Carlisle

@UlrikeFischer it is consistent with this, I guess

\documentclass{article}
\begin{document}
\hyphenchar\font = 100

{ \hyphenchar\font= 200 }

\showthe\hyphenchar\font

\end{document}

(with latex)

Ulrike Fischer

@DavidCarlisle yes.

David Carlisle

@UlrikeFischer I know (I tested first:-) but it is what I guessed:-)

@UlrikeFischer luatex has a manual! The global nature can almost be deduced from: When you assign the values of one of these four parameters, you are actually changing the settings for the current \language, this behaviour is compatible with \patterns and \hyphenation.

Ulrike Fischer

@DavidCarlisle ;-). But I think Will didn't realize it. He use \int_set and not \int_gset in fontspec.

@DavidCarlisle I did read the manual ;-). But I'm not sure if I would had deduced the global nature from this. But I think at the values are tied to language that fontspec shouldn't set them in the font initialization.

David Carlisle

@UlrikeFischer oh it's same as texbook you need to work out the behaviour by testing or reading the source, then interpret the manual.

3

@UlrikeFischer not setting them per font sounds like a good idea

Joseph

17:58

Inspired by @marmot, there is a question nagging me, if it can be answered at all: "Is there anything that can only be done in TeX but not in LaTeX"? -- or should I post it as a question?

Ulrike Fischer

@DavidCarlisle yes, I will wait a bit if the OP from tex.stackexchange.com/q/468140/2388 does it, and if not I will do it.

Joseph

or is it a really silly question?

By the way, happy new year for ye all. :-)

David Carlisle

@Joseph no question is silly, but it's not really answerable, or the answer is "no" (or perhaps even "yes") depending on your definitions.

Joseph

@DavidCarlisle, that's more or less what I thought.

Paulo Cereda

@DavidCarlisle LaTeX ⊆ TeX?

@Joseph Happy new year, pal! :)

Joseph

18:09

@PauloCereda, and for you too!!!

David Carlisle

@PauloCereda or TeX ⊆ LaTeX depending on your definitions:-)

anyone having duck for new years day dinner?

Paulo Cereda

@DavidCarlisle ooh :)

@DavidCarlisle oh no

@DavidCarlisle you are mean

marmot

@ChristianHupfer I beat you. You only got one downvote on meta recently, but I got two. And almost certainly by the same user. (His total downvote # was 0 before you received it, jumped up to 1 then, and is at 3 after my two downvotes.)

David Carlisle

@PauloCereda @DavidCarlisle you are mean

Joseph

@PauloCereda, just came across a fellow claiming that thesis class authors (you know what I mean!) will benefit from a Portuguese translation of gnu.org/software/teximpatient because, well, TeX can do unspecified amazing things that Latex can't.

David Carlisle

18:11

er I think I copied the wrong link

Paulo Cereda

@DavidCarlisle hm?

@DavidCarlisle ooh a flaw

David Carlisle

Jan 12 '16 at 12:15, by David Carlisle

@PauloCereda finished your thesis?

Paulo Cereda

@DavidCarlisle oh no

Christian Hupfer

@marmot I know, I have the 'proof' as screenshots ;-) A little bit of paranoia, I know ;-) But it's sad.

Paulo Cereda

@Joseph oh my!

Joseph

18:13

@PauloCereda, I remember this question being asked so many times... they'll never forget your thesis.

Paulo Cereda

@Joseph The funny thing is that there's a particular remark on my thesis regarding this... hold on...

Joseph

@PauloCereda, yes, teach plain TeX in Portuguese to Brazilian thesis class authors (if such a thing exists) and you'll see top-notch results, presto!

marmot

@ChristianHupfer Yes. But that's how democracy works. It is his right to do that.

Joseph

@PauloCereda, I guess I've read it in your thesis somewhere...

Paulo Cereda

@Joseph there we go again. :)

Christian Hupfer

18:15

@marmot It's my right to ignore him as well.

Paulo Cereda

@Joseph cannot wait to have ABNT for pure plain TeX.

marmot

@ChristianHupfer Yes, sure. In this case it is not just your right but probably the only reasonable option.

Paulo Cereda

Which defeats the very purpose of using plain TeX in the first place. :)

David Carlisle

@PauloCereda you could use this:

A: Is there any software that converts latex file to tex file?

Adding \def\patterns#1{} \catcode`\{=12 \let\newtoks\relax \let\dump\relax \let\+\relax \let\newinsert\relax \input latex.ltx To a LaTeX file makes it a plain TeX file. This is a LaTeX answer I gave to a question earlier today which runs without error in pdftex as modified: \def\patterns#1{}...

Paulo Cereda

@DavidCarlisle sir, you are a living legend

Joseph

18:18

@PauloCereda, that's what I asked the guy, what do you want to do with it, he said, "look, I can do pie charts in tex but not in latex". kkkk I was like: LOL

Paulo Cereda

The Queen should give @DavidCarlisle a Knight title.

@JosephWright ^^ help

@Joseph LOL

Ulrike Fischer

@DavidCarlisle Ich verweigere die Aussage ...

Joseph

"my supervisor asked me to convert something that I wrote with LaTeX into TeX style because he only knows how to use TeX." that's mean.

Joseph Wright

@Joseph Oh great, one of those

Christian Hupfer

@marmot Aggressive people feed their emotions from attention. Ignoring them can (!) help

David Carlisle

18:20

@UlrikeFischer that translates as "yes, but I dare not say" ?

Christian Hupfer

@DavidCarlisle Does duckless fried potatoes with ham, egg, cheese count as well? ;-)

marmot

@ChristianHupfer I know. I am only worried about him being a teacher. Poor kids!

Christian Hupfer

@marmot I am worried he is a 'colleague' of mine ... well not really. He is doing the same 'job' ...

David Carlisle

@ChristianHupfer did you have any pineapple with the ham (they go well together, as is well known)

Ulrike Fischer

@DavidCarlisle No comment. Ask my lawyer.

Christian Hupfer

18:23

@DavidCarlisle No, we dipped the potatoes in plum pudding and arranged with sliced haggis ....

David Carlisle

@ChristianHupfer sounds like an excellent pizza topping to me.

marmot

@ChristianHupfer The profile says: "Junior High School mathematics teacher". (I will always remember my first high school year, where my math teacher also taught religion. If you solved a math problem in a way she did not teach, you got 0 points. I had one exam in which all final answers were correct and I got a 6 since none of the derivations coincided with what she taught us. ;-)

Christian Hupfer

@DavidCarlisle I did not expect something different from Britons :D

Joseph

@PauloCereda, seeing German around, now I've been motivated to study German because of my daughter. Maybe it's "good karma", or just to settle the score. Perhaps now I can read the original Koma doc's.

Paulo Cereda

@Joseph That's a good motivation, surely. :) Then you can help me relearn Koma again. :)

Christian Hupfer

18:25

@marmot Stubbornness is a problem with many teachers, yes, especially with the 'aged' ones

marmot

@ChristianHupfer Yes. In my Facharbeit I also got a mediocre score simply because the teacher did not understand the maths. ;-)

Christian Hupfer

@marmot String theory at that time already? ;-)

Joseph

@DavidCarlisle, I've got a pizza menu in front of me in which there are delicacies like "nutella, strawberry and power milk pizza", "chicken heart pizza", "pork rib pizza"...

Paulo Cereda

@marmot Damn you Nambu-Goto!

David Carlisle

@Joseph don't tell @CarLaTeX or she may not survive far into 2019

marmot

18:29

@ChristianHupfer No, it was as simple as epicycles and such things. (Looking back I actually do not understand how one can write several pages on these things.)

Paulo Cereda

@Joseph @DavidCarlisle ooh Nutella pizza is good

Joseph

there is also "fried pork belly [torresmo] pizza"

marmot

@PauloCereda You can use Polyakov instead.

Paulo Cereda

@Joseph HOLY COW TORRESMO YES

@marmot ooh Russian

marmot

@PauloCereda No, no square root. (So sad that Polchinski passed away, his books are really good.)

Joseph

18:31

@PauloCereda, why haven't I though of this before? so perfect! must come with some lemon.

Paulo Cereda

@marmot I have a collection of Russian books (translated to English, of course). TCS and Mathematics are great.

@Joseph A million dollars idea. :)

CarLaTeX

@Joseph @DavidCarlisle I see no pizzas on that menu

Christian Hupfer

@marmot Well, we don't teach epicycles in Math; I mention them only short in Physics, when talking about the geocentric system of the classic and middle ages world until Kopernikus.

Joseph

@CarLaTeX, well, it's practically across the street from where I live. although I just ask the usual bacon and chicken, it's delicious

marmot

@PauloCereda Sure, there are many brilliant Russian mathematicians. One of them prefers picking mushroom over picking up the Fields medal. ;-)

Paulo Cereda

18:34

@marmot oh that one I don't know, what happened?

marmot

@ChristianHupfer Yes, sure. We also didn't get this stuff taught. That's why one could write a Facharbeit on this.

Harald Hanche-Olsen

Grigori Perelman

Grigori Yakovlevich Perelman (Russian: Григо́рий Я́ковлевич Перельма́н, IPA: [ɡrʲɪˈɡorʲɪj ˈjakəvlʲɪvʲɪtɕ pʲɪrʲɪlʲˈman] (listen); born 13 June 1966) is a Russian mathematician. He has made contributions to Riemannian geometry and geometric topology. In 1994, Perelman proved the soul conjecture. In 2003, he proved Thurston's geometrization conjecture. The proof was confirmed in 2006. This consequently solved in the affirmative the Poincaré conjecture. In August 2006, Perelman was offered the Fields Medal for "his contributions to geometry and his revolutionary insights into the analytical and geometric...

marmot

@HaraldHanche-Olsen You beat me by one second! ;-)

Paulo Cereda

@HaraldHanche-Olsen Danke! :)

CarLaTeX

@Joseph Never seen a bacon and chicken pizza

Joseph

18:38

@CarLaTeX, next time I order one I'll take a picture. ; -)

Paulo Cereda

@Joseph She will faint. :)

CarLaTeX

@Joseph Are you telling me you're going to eat it again? Omg!

Joseph

@CarLaTeX, sure, its borders are also filled with "catupiry" cheese: en.wikipedia.org/wiki/Catupiry. Yummy.

I'm sure I already shared some more bizarre pizza flavors, but here it goes, for a blasting New Year ahead, full of new culinary experiences: dailymail.co.uk/femail/food/article-3306019/…

CarLaTeX

@Joseph Better don't know what foreigners do with our pizza

Joseph

@PauloCereda, when people take my attention off LaTeX and German and say there's something on TV...

David Carlisle

18:53

@PauloCereda I see your new president uses a British car

marmot

19:13

@DavidCarlisle `Maybe he wants the steering wheel also to be far right?

boycott.se - yo'

19:38

@DavidCarlisle No, it's not.

David Carlisle

@boycott.se-yo' You sure?

@marmot where else would you put a steering wheel?

marmot

@DavidCarlisle Well, if you drive on the right (as opposed to wrong;-) side of the road, you may prefer having it on the left.

AndréC

@marmot @ChristianHupfer I do with you what you recommend about me without doing it: I ignore you Happy New Year :-)

David Carlisle

@marmot the important issues of the day:

WHO WON??????? — David Carlisle 6 hours ago

marmot

@DavidCarlisle I think it was Trump. ;-)

David Carlisle

19:52

@marmot does he have a nice sweater?

marmot

@DavidCarlisle Really beautiful. The best sweater of the world! Believe me!

David Carlisle

@marmot Imported specially from China?

marmot

@DavidCarlisle Pssssht!

boycott.se - yo'

20:07

@DavidCarlisle well, a number is even if it's divisible by 2, not if it's positional notation ends in an even digit.

@HaraldHanche-Olsen he's great! :)

Harald Hanche-Olsen

@boycott.se-yo' Well, if the base is even, the two are equivalent. But in an odd base, a number is even if and only if there is an even number of odd digits.

boycott.se - yo'

@HaraldHanche-Olsen exactly :-)

Harald Hanche-Olsen

@boycott.se-yo' Fun fact: Both Even and Odd are perfectly ordinary male names in Norway.

boycott.se - yo'

@HaraldHanche-Olsen lol

marmot

@HaraldHanche-Olsen Is there a rule that the first one has to have the name Odd and the second Even? ;-)

Harald Hanche-Olsen

20:22

@boycott.se-yo' And there is this story of a Norwegian named Odd who had emigrated to the US, he was so tired of people making jokes about his name he decreed that his gravestone should not carry his name. So when people see this stone in the graveyard, carrying only a birth date and a death date, they say, “Now, that's odd.”

@marmot If the parents are computer scientists, the first one will be Even, the second Odd. If they're mathematicians, it's the other way 'round.

marmot

@HaraldHanche-Olsen I see. This will prevent mathematicians from marrying computer scientists, and vice versa, I guess. ;-)

Harald Hanche-Olsen

@marmot What a sad thought!

@marmot But if they have female children, no problem.

marmot

@HaraldHanche-Olsen Hmmh, does that mean they need to divorce if the kids turn out male? That would be really sad. (But I guess Norway has a bit more than just two male names... so if they are clever enough, and one of them sure is, no problem. ;-)

Harald Hanche-Olsen

@marmot Um, yes, we have a few more male names to choose from. My own, for example. It means something like “mighty leader of armies”. Which, applied to me, is rather ridiculous.

marmot

@HaraldHanche-Olsen You could lead an army of bees.... ;-)

Harald Hanche-Olsen

20:33

@marmot Males are at the bottom of the social hierarchy of bees. Anyway, my avatar is a fly, not a bee. Though it mimics a bee, in order to dissuade others from eating it.

marmot

@HaraldHanche-Olsen Too bad. I was hoping you could help with the honey liquor production.

Harald Hanche-Olsen

@marmot Sorry. I plan to start brewing beer, though. I started buying the equipment, and will probably brew my very first batch soon.

@marmot It might be fun to try to brew some mead, however.

marmot

@HaraldHanche-Olsen I will be happy to help you with the tasting. ;-) (Need to leave.)

Harald Hanche-Olsen

@marmot Well, see you later. Ciao!

Skillmon

What is the reason for doing \noalign{\ifnum`}=0\fi instead of \noalign\bgroup?

Harald Hanche-Olsen

20:49

@Skillmon Both seem rather odd to me. Context?

Joseph Wright

@Skillmon See Appendix D

@Skillmon Master counter: see Appendix D

Harald Hanche-Olsen

@JosephWright Ooh, I see … need to look at that when more awake than now …

Skillmon

@HaraldHanche-Olsen say you want to define some macro in a tabular doing stuff which requires a \noalign and then some parsing, e.g. with \@ifnextchar[.

Harald Hanche-Olsen

@Skillmon Yeah, but bedtime is too close for such shenanigans (for me). Looks intriguing, though. I'm outta here, g'night!

David Carlisle

21:08

@boycott.se-yo' agreed, so 9102 is even, even if it's written right to left;-)

@Skillmon favourite grouping construct of tabular hackers:-)

caverac

Happy new year people! My best wishes for all of you

boycott.se - yo'

@DavidCarlisle sorry, I completely lost you now.

David Carlisle

@boycott.se-yo' the original comment was 9102 annotated with some bidi over-ride characters:-)

boycott.se - yo'

@DavidCarlisle ah ok. I, for some reason, thought the number 2019 was discussed. Sorry for that.

David Carlisle

@boycott.se-yo' no need to apologise, my use of 9102 was intended to deceive:-)

Skillmon

22:10

@DavidCarlisle Yep, still I don't really get why \bgroup isn't preferable, though.

David Carlisle

@Skillmon because it doesn't work:-)

Joseph Wright

@Skillmon Master counter

@Skillmon What @DavidCarlisle said :)

David Carlisle

@Skillmon you need a literal { not \bgroup so you can "scan past" & and other halign constructs, but you can not have an unmatched { in a macro hence the dance with \ifnum and `}

@Skillmon actually that explanation would suggest \iftrue{\else}\fi ought to work, but it doesn't always due to the master counter weirdness @JosephWright mentioned.

Joseph Wright

@DavidCarlisle Like I said earlier, Appendix D

David Carlisle

@JosephWright sure, but every question here could be answered with "Appendix D" :-)

7

@JosephWright any thoughts on normalising l3build linebreaks (so the latexbug test suite passes here?)

Joseph Wright

22:21

@DavidCarlisle Meanwhile, I'm close to automating all of the table generation for the FPU follow-on article (@barbarabeeton might be interested in that)

@DavidCarlisle The absolute path issue?

David Carlisle

@JosephWright yes or at least length of absolute path causing linebreaks at different places

Joseph Wright

@DavidCarlisle We are back with setting the line length to something massive, I guess :(

David Carlisle

@JosephWright that thought did occur to me

Joseph Wright

@DavidCarlisle Great!

David Carlisle

@JosephWright always (so breaking a lot of current tlg) or as an l3build variable so can just make it big enough when needed?

Joseph Wright

22:24

@DavidCarlisle Yeah, probably as a variable

David Carlisle

@JosephWright it's not really an issue in the core tests as everything copied locally there

Joseph Wright

@DavidCarlisle Very true

David Carlisle

@UlrikeFischer would be happy I think, as it affects the luaotfload tests I think

@JosephWright do you have to set it in the environment?

Joseph Wright

@DavidCarlisle I'll have to check: I think we can set it as an env. var, which can be done within the script

David Carlisle

@JosephWright yes that's what I think I remembered we tried before.

Skillmon

22:34

@JosephWright Yes, I'm reading, but it takes a while reading while sitting around your family who are watching a movie (concentration is a valuable thing)

Ulrike Fischer

@DavidCarlisle @JosephWright well for luatex I would prefer a callback that force the filenames on a new line. Imho that would be safer then longer linewidth. E.g. something like this:

\documentclass{article}
\usepackage{luacode}
\begin{luacode}
local function sanitizefilename (category,filename)
 filename= string.gsub(filename, ".+texmf","")
 texio.write_nl(filename)
 texio.write_nl("")
end

luatexbase.add_to_callback('start_file', sanitizefilename, 'sanitizefilename')


\end{luacode}

\usepackage{tikz}
\begin{document}
blujb

\end{document}

David Carlisle

@UlrikeFischer yes, but if you need a long length to get consistent xetex results, the lua callback may not help so much. For luaotfload that's not an issue of course...

Ulrike Fischer

@DavidCarlisle it is naturally not a solution if you want to compare with other engines. But if you do engine/luatex specific tests, that's imho the easiest. Perhaps there could be an option to activate such a callback?

David Carlisle

@UlrikeFischer yes I have a callback enabled in test2e.tex (which the core tests use instead of regression-test.tex) could just define your callback as a macro in regression-test then any test using it could use \STARTFILENEWLINE or whatever

Ulrike Fischer

22:50

@DavidCarlisle would be fine.

marmot

23:30

@DavidCarlisle The ducks were all busy so we had my sister in law over for dinner.
