@barbarabeeton Of course

@Johannes_B Well, I am living in a small town -- all three cars honked ;-)

@UlrikeFischer It s a bit late for the answer, but I need it actually for calculations for my FillPages-Package. Things like I, II, II, 1, 2, 3, 4, ... are quite common. And this messes up my calculations. It has still some bugs, but soon it will be published. It inserts pages on specific points, that the total page number equals a value dividable by x.

Well, when I'm thinking about it once again, I think you are right. But it makes sense for gobble.

@ChristianHupfer :-D

@Johannes_B Not much done here in chat this morning ;-)

@ChristianHupfer Pretty silent in here.

Attended a little birthday party yesterday, Pulled Pork and Schichtfleisch.

@Johannes_B The correct song for this ;-)

@ChristianHupfer I am not a big fan of DM.

@Johannes_B I am also no fan, but the song suits for the silence :D

@ChristianHupfer We have to break the silence.

@Johannes_B @egreg will love this ;-)

@ChristianHupfer Sure. I do :-)

@Johannes_B I am no fan of electronic music

@ChristianHupfer That is not electronic music, it is a classic ;-)

How was yesterdays event?

@Johannes_B Did not take part

hi guys!

Can you help me with this error:

@AbhishekBhatia Hi.

\begin{equation}
\begin{split}

\end{split}
\label{eqn:phys}

@AbhishekBhatia Hello -- there are not 'only' guys in here ;-)

It shows me the Error: Missing delimiter (. inserted). \end{split}

\right \} perhaps (untested)

@AbhishekBhatia Or \right.

@Johannes_B shows Extra \right. \end{split}

@AbhishekBhatia Maybe the cases environment would be a better match here?

@Johannes_B true, if there should be no right } at all

@ChristianHupfer Removing \right it gives Extra }, or forgotten \right. \end{split}

@AbhishekBhatia I did not say remove \right, I wrote \right \} ;-)

@AbhishekBhatia vvvvv

@Johannes_B Thanks!!! Why did to use \def?

@AbhishekBhatia Because it is shorter for this example. Don't use \def in your documents.

@Johannes_B okay, thanks. Cases does work better.

@Johannes_B wipet would disagree with this :-P

@ChristianHupfer Don't use \def in LaTeX documents. ;-)

@Johannes_B Well, depends on your ill-doings. \def\foo#1/#2 can be quite convenient etc.

@ChristianHupfer tex.stackexchange.com/questions/317708/… Answer: Use InDesign.

@Johannes_B Starting users are overburdened with using the right document class already ;-)

@ChristianHupfer True as well.

@Johannes_B Done with all lab reports -- I hate to read them. Always stupid errors

@ChristianHupfer Just as much as I liked yesterday's shootout.

@ChristianHupfer Examples?

@egreg You mean this one:

spiegel.de/video/…

@Johannes_B No axis ticks, no units, wrong calculations, "Fehlerbetrachtung: Es könnten Messfehler entstanden sein" (OMG, wirklich?;-))

@ChristianHupfer Fehlerbetrachtung: Es herrschte Vollmond, somit sind keine Zusammenhänge zu tatsächlichen physikalischen Gegebenheiiten zu erkennen.

Title page - Wikipedia, the free encyclopedia claims that it is usually verso. However, if I look at the books I have, I think it is recto. As far as I understand it, the third picture shows a title page on right side, i.e., recto.

I am confused.

@wilx "The title page is one of the most important parts of the "front matter" or "preliminaries" of a book, as the data on it and its verso "

@Johannes_B Yes, that is what confuses me.

Because either I am misidentifying or misunderstanding what is a title page or it is different in the European books I own.

@wilx But it basically says: The data on the titlepage and its backside (verso) ... making the titlepage recto

Aaaaaa! Its vs it's.

@JosephWright Can we reopen and close after adding an answer by me? I would be fine with deleting the question as well, since it is ... not very good. tex.stackexchange.com/questions/245967/…

@Johannes_B Oh my god, what beautiful markup ;-)

OK, I am still a bit unsure about how LaTeX understands things... So, if title page is recto, as we have established, what is the first page in PDF document labelled 1? Is it right page or left page? In my current understanding, it should be (or I want it to be) right page. Does LaTeX agree with me?

@wilx The first (in total counting) page should be recto, in my point of view.

@ChristianHupfer OK.

@wilx Now, since \thepage can contain anything (basically), this is not necessarily printing the real page number

@ChristianHupfer I am asking because of the margins and such.

Is it OK to reduce the outer margin if the text has no side notes?

@wilx Principally I would say: Yes, but this depends on your targets, of course

@wilx well, IMHO no. The margin is not there for the margin notes, it's there for the look.

@wilx If the page counter is odd, LaTeX makes a recto page. By definition.

@Johannes_B OK.

@ChristianHupfer By the way, a class file that has comment signs in front of the geometry stuff and does stuff with anymargin.

@yo' That's a personal opinion -- it depends on the document, I would say. If the margins have 0.4 of the full page width I would agree with you

@Johannes_B which class?

@ChristianHupfer The oneside/twoside, openany question.

@Johannes_B Ah, your reply links to another comment however. Don't do that!

@ChristianHupfer I can't help it. I didn't link it to anything.

@AbhishekBhatia -- i know this has already been addressed with cases, but the real source of the error is that \left \{ is before \begin{array} and the \right (which should be \right. is inside the scope of array when it needs to be outside. order matters.

@ChristianHupfer -- not so sure of that -- \cases{...} is defined in amstex.tex, which is certainly a plain tex macro collection, and i think works with opmac.

@barbarabeeton I don't claimed anything, I think

@ChristianHupfer Either my perception has changed, or the questions today are more vague than usual.

@Johannes_B masi mode ;-)

@ChristianHupfer :-)

@ChristianHupfer A questionaire with beamer?

Removing scheme-full, my last step in trying to make colorbrewer work

I have used stackengine for something useful! I am so proud of myself. :)

Would somebody mind testing the following example and tell me if the capital letters of the journal field stay capital or of they are lower cased?

I am sure people made fun of me because of penalties. :)

@Johannes_B Upper case (still on TL2015).

@TorbjørnT. TL15 here as well. latex-community.org/forum/…

@Johannes_B I get an error and lowercase letters. With babel the error goes away and lowercase in english and uppercase in german.

In TL 16, in Tl15 it is uppercase.

@UlrikeFischer The OP didn't mention an error, and is using babel.

@Johannes_B Well as he/she is using babel, there would be no error. The described behaviour is what I get with TL16.

@UlrikeFischer But the described behaviour is the documented behaviour, right?

@Johannes_B Well it is a possible behaviour, if the style use \MakeSentenceCase. I didn't check if biblatex-ieee changed something here, ask @JosephWright´. You can use \DeclareCaseLangs{} to disable it.

I have just 100 MB of free space on my HDD. I need more space.

@UlrikeFischer I linked to this part of chat, i hope the OP reads it :-) Thanks for your help.

@egreg -- would it be likely that anyone would want to use a fraction with \bmod? (tex.stackexchange.com/a/317786) (not nearly as straightforward, and maybe it wouldn't be useful to consider it, but seemed worth asking.)

@barbarabeeton \bmod doesn't take arguments

@PauloCereda I just remembered a couple of the last great successes of the Seleção. ;-)

@egreg -- i know that. but is use of a fraction reasonable there? (i'm thinking from the point of view of documentation; in the amsmath documentation, they're all treated together, and if automatic sizing were to be offered, it would be reasonable to say how to get larger, matching parens when the documentation is updated.

@barbarabeeton Not sure what's the point here: \[\left(a\bmod\frac{b}{c}\right)+d\] works out of the box.

@barbarabeeton It would be no different from [\left(a+\frac{b}{c}\right)+d]

@egreg -- okay. the present documentation in amsldoc for \bmod is "\gcd(n,m\bmod n)", which sort of throws in something that could be misleading. since i may be the one updating that manual, i'd like to avoid confusion. (michael tried pretty hard to create reliable documentation, and i'd hate to overturn that.)

@barbarabeeton There's a big difference: \bmod by itself doesn't produce parentheses, which is the duty of \pod and \pmod; neither \mod does.

@egreg -- yes, that's obvious, but i'm not looking at it from the code point of view, but how best to document it for a user. maybe just something to the effect that if fences need to be made larger, it has to be done manually (whether with \Big and friends or with matched delimiters is then irrelevant).

@barbarabeeton I'm not seeing any issue: if you need larger fences for \gcd(a\bmod \frac{b}{c}) the standard method applies. The fences here are explicit.

@barbarabeeton Maybe just a note that \bmod essentially works like a binary operation symbol, which people seem to ignore, actually: I see instances of wrong \bmod and \pmod all the time.

@egreg -- i agree. i'm just trying to mentally rework section 5.2 of amsldoc, where all are lumped together. (and yes, they're often misused. just don't want to add to that confusion.)

@egreg <3

@PauloCereda /me still sobbing

@egreg /hugs

Pesky Germans!

@PauloCereda Black Forestrians in particular. ;-)

@egreg ooh definitely. :) @ChristianHupfer

@Johannes_B: Is that H? ;-)

@PauloCereda No cookie parcels for you any longer :D

@ChristianHupfer You are firing at me with my own weapons. This is a comment completely out of context. :-) What are you referring to?

@egreg For you neither :-P

@Johannes_B Nur damit Du siehst we beknackt das ist :-P

@ChristianHupfer oh :(

@Johannes_B: Der Vogel hier: tex.stackexchange.com/questions/317806/…

@ChristianHupfer Ah, ok. Grießbrei :-)

@ChristianHupfer I know one thing: It cannot be the user that was bugging me on FB, but it is the same caliber (if that is a valid expression in english).

@Johannes_B Ask @DavidCarlisle on that term -- he's knows some English, I've heard ;-)

@ChristianHupfer I was asked yesterday how many languages i am speaking.

@Johannes_B And the answer was....?

@ChristianHupfer Laura answered before i could say anything with All of them. (see fb msg)

@ChristianHupfer I have left the link about an hour ago to another question. If s/he wold have clicked and read, there wouldn t be a need to ask another question.

Duplicate, I think

@PauloCereda Alright, one cookie parcel per decade then <3

@ChristianHupfer oh

;(

@PauloCereda A parcel per quarter? <3 <3

@ChristianHupfer :)

my car has broken down :(

@yo' Oh no!

@yo' Did your car use the latest LaTeX engine update? ;-)

@ChristianHupfer heavens no!

SPAM SPAM SPAM

@ChristianHupfer thanks thanks thanks (please, remove the onebox above by adding some contents to the message, it's better not to onebox spam)

@yo' Too late :-(

@ChristianHupfer nevermind, this one does not contain malicious links, company names and stuff. But it's good to remember this for the next time :-)

@yo' Yes, my master ;-) (Deep breathing sound)

@ChristianHupfer oh no :(

Please, does anybody know how should the eszett be treated in a caps-only font? What is correct from Unicode's point of view?

@yo' Tricky question. I would say u+1e9e. Some parts of german official thingies agree, cartographic names have to keep the eszett in capital letters. German orthography would say ß -> SS, which is a leftover from using another writing system.

@Johannes_B Well, the font has identical glyphs present in uppercase and lowercase slots (meaning A and a look the same), and it has the eszett glyph (a wrong one actually, looks like lowercase eszett, which is plain wrong) in the lowercase slot u+00df, but not in the uppercase one.

@yo' What kind of magic are you working on?

@Johannes_B not me, the Czech Scout Movement. I tell you, the font is ... one of the ugliest that someone considered professional. I'm only trying to save the case.

@yo' :-)

@Johannes_B There are also (rarely however) surnames having ß ... like Janßen etc.

@ChristianHupfer Strauß.

@Johannes_B Groß ;-)

@ChristianHupfer I once stand on an ostrich egg. That thing was huge.

Meißen

Hello, I need some help again with \expex pack for interlinear text. I do not know if the command \gla accept linebreak... I want to put a poem in the field of \gla. And if anyone know a method to avoid the use of \begingl - \endgl in each verse

Off-topic?

LOL

i think so, it's something very specific of each editor gui... he/she could even use VIM or something with large font size.

@PauloCereda BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

@PauloCereda: I will have to rethink my cookie distribution scheme, apparently ;-)

Ok i have no idea whatelse to do with this colorbrewer... Just did a fresh install out of "box" TexLive 2016, and still get the same error. :(

@DavidCarlisle: quack! :)

@DavidCarlisle Hello, have you any opinion on this, please?

@PauloCereda Hello. Do you know if I can use the "bend" command in tikzcd to create a "U" shaped arrow?

@PedroTamaroff Hi! :) Oh I am so sorry, TikZ is definitely not my cup of tea... :(

Oh, OK.

Hopefully the folks in here might be able to provide a nice answer for you. :)

@yo ^?

@yo' I don't see why it should be different than in other fonts: for unicode the lowercase is U+00DF and uppercase is U+1E9E. From the design I prefer for small caps a look like "SS" instead of some sort of larger ß, but this is naturally a decision of the font designer.

Found something here.

@UlrikeFischer well, you're probably right. I just wasn't sure how German people prefer it, I have a feeling that all-caps fonts are specific.

@UlrikeFischer Most u+1e9e i have seen so far have been really really ugly.

@yo' Most germans don't know about a capital eszett.

@Johannes_B yeah, so what would they expect from an all-caps font?

@yo' I would sayL Nothing. If the font is suitable and the capital eszett matches the rest, they wont even notice.

@yo' I once had a wild argument that football is spelled Fußball with a bunch of guys, because some yellow papers like to do all caps DAS FUSSBALLWUNDER VON XYZ. Which, according to german orthography is correct, but Fussball is not.

yellow papers is wrong, what is it called?

@Johannes: when I started to learn German (because of the lovely teacher girl, of course), she told me I could replace ß by ss all the time, but not vice-versa...

I don't know anymore. :)

@PauloCereda That's wrong, even with the new (rubbish !!!!!) German spelling rules

@ChristianHupfer Thought so, but I hadn't paid too much attention either. :)

@PauloCereda I wonder what you paid attention to ;-)

@ChristianHupfer oy I am a very respectful duck. :)

@PauloCereda Proofs, please ;-)

@Johannes_B yellow pages

@ChristianHupfer \begin{proof} ... \end{proof}

@yo' Ah.

^^ :)

@yo' facebook.com/versaleszett/?fref=ts

@Johannes_B Das Sehryellowpages. :)

@PauloCereda :-)

El pato

@yo' Sure a small "a" looks like "A" in small caps, but this design and not related to unicode code points.

@PauloCereda Listen, any ducks that live on/in/at ponds and write \begin{proofs} are no reliable source ;-)

^^ This is what happens currently. Obvoiously eszett is wrong (the glyphs is minuscule), and ESZETT is wrong (the glyph is missing and a a substitute is used). But what should actually happen?!

@ChristianHupfer :)

@yo' Just substitute with SS. Nobody will notice, and if, they won't care.

Germans are used to bad typography.

@Johannes_B how do you mean it? Put "SS" as a glyph in both unicode positions? But isn't there then a problem with line-breaking?

@yo' Everything concerning the capital eszett is not really defined, right now. You pretty much can do what you want. Map ß to SS, as the kernel does by default. What unicode actually does, no idea. Ask @Joseph, he implemented something for the L3 kernel. :-)

@Johannes_B OK. Thanks.

@yo' Out of ten germans, 9.7 haven't noticed that there officially is no capital eszett.

@yo' ask a German:-)

@Johannes_B lol. I really care about 2 things: (1) what is official Unicode Consortium opinion. (2) What do German typographers such as you or @Ulrike think.

@DavidCarlisle any idea if Unicode Consortium has any opinion on this? Is it possible to find it anywhere?

@yo' I am not a typographer :-) Ask Erik Spiekerman or Nadine Roßa (<- she cares :-) )

@Johannes_B I'll write her, thanks!

@yo' The capital eszett (by the way, i also sent you a fb msg with that link, don't wonder) is a thing of post-2k. Right now, you cannot just hit a keyboard button to get a capital eszett. If you do Shift+ß you get a question mark. I had an email from a person from the consortium, that decides about german spelling, and she wrote: If the capital eszett is acknowledge by the majority of people, it will be included in the german alphabet.

So, please use it (if you find a suitable font). Prepare banners and stuff so people notice the lack.

@Johannes_B I haven't got any message :(

@yo' Imho the best looking version is the "STRAUSS" but then I'm rather traditional ... and again don't confuse the code point and the graphical representation. In traditional tex T1-encoded fonts the "SS" you get from an uppercase ß is a single glyph!

@UlrikeFischer ok, thanks. And is there any case where eszett behaves "weird" with hyphenation?

@yo' So another Tom got the message :-)

@yo' youtube.com/watch?v=F_nfFKAe6NM

@Johannes_B I know that vid.

@yo' Sehr gut :-)

@Johannes_B and I agree with that vid personally, but ... but. (You see, you and Ulrike have different opinions and both are Germans and both have a thing for typography.)

@yo' The swiss ... they just got rid of eszett completely. So it is a matter of usefulness/taste/whatEver.

@yo' I have to agree with @Ulrike, that STRAUSS looks best. The rest looks like ... "Ehm, boss, the glyph. Ehm. i don't have it here in this box. What should i do?" "Just take one from that box. I don't care."

mail to Nadine Roßa sent. I'll see what she replis

@yo' Unicode doesn't seem to list capital sharp s and sharp s as upper or lowercase versions of each other. But personally I think it's clearly β → Β :-)

@yo' @UlrikeFischer Can anyone help me out with some bending in TikzCD?

@PedroTamaroff you have asked before, I saw it. Have you got a MWE? If so, why don't you ask a question? :-)

@yo' Hm, I just want to bend an arrow. Yes, I have a MWE.

I want to replace the only vertical arrow there by a curved arrow on the side.

@PedroTamaroff well, a MWE should start with \documentclass and end with \end{document}, but ok, I can look into that now.

@PedroTamaroff Have you tried \arrow[bend left]{d}{\partial} or \arrow[bend left=90]{d}{\partial} ?

That looks nicer, but I want the arrow to look like a U-turn.

@PedroTamaroff see the 2nd option

So it has to go horizontally for a while, then bend down, the go horizontally again.

@PedroTamaroff that's really too complicated for 11pm :D

Ah, yes. That's better.

I'm happy with that option. =)

@PedroTamaroff ok. You're welcome

@yo' I agree with the video that a code point for a capital ß is useful. But the look is a different question. lowercase and uppercase can be quite different (see e.g. greek, or "g" versus "G", and so the idea that the uppercase ß has to look like the lowercase is not very convincing.

@UlrikeFischer yeah, the type drawers have to design the letter, but IMHO the important thing is people realizing that it's useful. Also, note that for both S and Z, the lc and uc are similar, so they could be similar for an eszett, too

Somenone can help me with this: tex.stackexchange.com/questions/317831/… ??

@UlrikeFischer That is the difficult part. You know that A is uc a, and B is uc b. You learned that in school. In the cyrillic script, an i looks like an n to us, unless you know what it looks like. Now, imagine a new letter in the alphabet that everybody knows (lc), but nobody knows (uc). Imagine the uc eszett to look like a spiral or an appple, people would get confused. But if it looks just (a bit) like a big lc eszett, i think it is easier.

@Johannes_B Most german are quite used to see an SS for uppercase ß, so I don't think it would confuse them if the glyph looks like this.

@UlrikeFischer SS, yes. But a completely different thing.

@UlrikeFischer As said a bit above, my friends trying to convinve me that the sport is called Fussball, made me a bit ... pro-capital-sharp-S

@Johannes_B I personally share this point of view. Let's stick to something known. Maybe in 20 or so years, a better alternative will be found.

@egreg but my answer is more informative;-)

@DavidCarlisle No.

@egreg well I'll vote dup anyway

In any case, you should answer the other question, if you think you have a better answer.

@egreg bah humbug

I am hungry...

@PauloCereda Get a cookie
