Could anybody tell me if it is possible to do something with vector resources such as those at allvectors.com/human-organs in order to use the images in PDF documents, preferably in vector format but otherwise not? The format is given as EPS but it is actually AI. When I open the file (on Linux), it opens in gv although Okular can also open it. But I'm not sure what to do next since I only want to use one organ at a time and they are all on one sheet.

@cfr I think it's possible to import these vectors into Inkscape and then export the image as .ps, .eps, .pdf or even export the result as a tikzpicture.

@PauloCereda Ah, Inkscape. That sounds more promising. I'll give that a whirl. Thanks.

Good Morning

@Serthy Good morning

Essential LaTeX editor features?

@Johannes_B Also tex.stackexchange.com/questions/339/latex-editors-ides, which shows there is not exactly a dearth of choices available

@JosephWright Morning. Thanks, he might be interested in a little overview. Good idea.

@cfr or you could just use ps2pdf to make it into a a pdf and then include it with \includegraphics, clipping to the desired part of page using the clip or trim etc options.

Good afternoon! Not really a TeX question, but someone might have an opinion.... I am putting together a document with lots of contributors from lots of countries and so lots of different personal and typographic styles. In itemized lists, where each item consists of a single sentence, what punctuation is the best way to end each item? If it's multiple sentences per item, I am guessing there should be fullstops. I never really thought about this before!

PS this document will (eventually) be in British English

@FionaSmith I think it depends on the editor's style. :)

@FionaSmith Sentences should end with full stops I'd say.

Good maen

@ChristianHupfer \u0027\u006c\u006f\u002e

@PauloCereda: mellon! :-P

Some people on the site is being mean to @PauloCereda, by remembering something painful. Seven times painful. ;-)

@egreg Uh-oh. :)

@egreg: apparently Claudio didn't like my Juve image in the meta question. :)

But I do not have a Milan one for him. :P

@PauloCereda I'd have used this image for the example

@egreg Oh no, Roberto Carlos' socks are back to haunt us. :)

@PauloCereda meta.tex.stackexchange.com/questions/4616/…

awww <3

@PauloCereda I am the editor! @DavidCarlisle Good. Thanks. A lot of them seem to use semicolons.

@FionaSmith Ah, so I think you should follow your heart. :)

@egreg: Mean to Paulo, that's against any law ;-)

@FionaSmith well, then they are not sentences:-)

Speaking of English, there's something smelly in this sentence: Unlike the cases when $b$ divides $a$ or $b$ is co-prime with $a$, in the general case, two more things have to be considered:

@tohecz it's probably correct (not that I know any rules of English grammar) but you have to re-read it a couple of the times starting from the inside, working outwards, so rephrasing it wouldn't hurt:-)

perhaps (assuming the preceding context) If $b$ divides $a$ or $b$ is co-prime with $a$, we have finished. In the general case, two more things have to be considered:

@DavidCarlisle thanks, I see your point. However, it's the first sentence of a new section titled The general case, after a section titled The case $b$ divides $a$

@tohecz ah not so good then. i guessed it was immediately following some itemized steps or some such. as I say the original isn't wrong I think, just a bit contorted

@tohecz OK perhaps bring "general" forward: In the general case, where $b$ neither divides, nor is co-prime to, $a$, two more things have to be considered:

@DavidCarlisle looks good :) I as well thought of: Unlike the two particular cases (when $b$ divides $a$ of when they are co-prime), in the general case, two more things have to be considered:

However, I'll end with your suggestion, thanks a lot! :)

@Johannes_B: No further reply from our enumerate-guy on LC?

@ChristianHupfer No, not yet.

@Johannes_B: Well, anyway... I sometimes think not to answer questions from unregistered fellows (although LC works differently, as I suppose)

I guess you all have seen this:

gitlab.brokenpipe.de/stettberger/avremu/tree/master

@topskip Holy cow!

@ChristianHupfer Most of the time i answer something, i learn a bit more.

From the FAQ: "Are you insane?"

@Johannes_B: That's the same for me, but sometimes it's not worth the effort ;-)

@ChristianHupfer A few minutes spent more or less on TeX. I don't keep track.

@topskip Now, provide a run visualizer and you'll get people from the theory of microprocessors actually use it for teaching :)

I would like to have some boxes of shaded background with title and a couple of paragraphs of text/math in them. These can be "reminder" boxes, more advanced calculations or just some "aside"s. I'm sure a package exists for something like, I don't have strict requirements on formatting, just want to have the box set apart.

Can you recommend packages for this?

@Szabolcs: mdframed or tcolorbox ...

@ChristianHupfer Thanks!

Anybody got an idea how to put a double (back and forth) harpoons in a tikz-cd diagram?

@Szabolcs also todo package

In math mode, can I put two aligned next to each other?

never mind, had a mistake elsewhere

does anybody understand this link: tex.stackexchange.com/questions/125274/…

i'm getting the following error in my code pertaining to the references: dpaste.com/3EWDZHB

i thought that link might be relevant

@DavidCarlisle are you good with references?

Bibtex?

@egreg: paulmccartney.com/news-blogs/news/… Note the last show in SP. :)

@PauloCereda Unfortunately, on 22 November we'll have Italy-South Africa in Padova. Rugby, you know. And on Tuesday and Wednesday I have lectures.

@egreg Oh no. :( But I do believe we have great news as well:

Probabilmente all'inizio la candidatura di San Paolo del Brasile per ospitare la prossima Supercoppa Italiana fra Napoli e Juventus avrà fatto sorridere i tifosi delle due squadre. Ma con il passare delle ore crescono invece le possibilità che la gara che mette di fronte la vincitrice dell'ultimo Scudetto e la squadra che ha conquistato la Coppa Italia si giochi nella metropoli verdeoro.

Il match si disputerebbe all'Allianz Parque, il nuovo stadio del Palmeiras che sta per essere ultimato e che costituisce una sorta di gioiello dell'architettura moderna: l’impianto ospiterà 43.600 spettato…

If I have a citation command inside of a section heading, is there a way to get the expanded citation to show up as the section heading in the PDF file rather than just seeing the citation key?

@PauloCereda That's very interesting!

@egreg If the game is really confirmed, I'll really try to go. :)

@JG doesn't look related, the dpaste link just says you have two groups started that are not closed at the end of the document so \begin{aaa}\begin{aaa}\stop would make that error

@DavidCarlisle I just figured it out. I needed to comment out the inconsolata font

thank you for looking at it

@AdamLiter you shouldn't be seeing the internal cite key, \section{zzz \cite{foo}} should make zzz [1] or whatever

@topskip Probably a friend of Bruno's

@DavidCarlisle I'm seeing the internal key. I'm using a different bib style, though, so maybe that's why?

Also, even with @egreg's usebib and \section[\usebibentry{potts2003}{author} (\usebibentry{potts2003}{year})]{\citet{potts2003}}, I just get () in the PDF file properties.

@AdamLiter oh you mean the pdf bookmarks not in the main header?

@DavidCarlisle Yeah, sorry for not clarifying.

@AdamLiter pah!, bound to be buggy, he knows nothing

@DavidCarlisle :P

@AdamLiter in that case basically it comes down to Heiko's pdfstring macros knowing enough about whatever citation package you are using

@AdamLiter usebib doesn't support the author field.

@egreg Ah, just saw that. I also realized I wasn't declaring \bibinput, however, when I try to do so it can't find my .bib file.

@AdamLiter Implementing the rules about authors would require implementing BibTeX.

@egreg I see. I really need to take the time to switch to biblatex one day ...

@AdamLiter The search path of \usebib is the same as for TeX files, not the one for .bib files.

@AdamLiter The best is if the .bib file is in the same folder as the main file.

@egreg Okay. Yeah, putting it in the same folder led to it finding the .bib file.

@AdamLiter For the application you have in mind, biblatex is the only tool; usebib is mostly a hack for accessing some of the fields, say title and url; the syntax rules for author are too complex.

Not impossible, of course, but tedious to implement.

@egreg Yeah, I think I will just type it out for the moment in the optional argument and try to find some time to transition to biblatex. :P Thanks!

@AdamLiter, see: as I said:-)

Would others check I've got this right?

@DavidCarlisle Haha, does that mean you can solve my problem, then? :P

@tohecz Did you figure out already?

@percusse yes, quite, it's a workaround but it works nicely :)

@tohecz :)

\[
	\tikzcdset{xharp/.style={harpoon,shift left=0.2ex}}
	\begin{tikzcd}[column sep=3em]
		\ol{\Z_b[\beta]_\f}
		\ar[r, "D"]
		\ar[d, xharp, "\bm h"]
	&
		\ol{\Z_b[\beta]_\f}
		\ar[d, xharp, "\bm h"]
	\\
		\AA^\omega
		\ar[u, xharp]
		\ar[r, "\text{(shift)}"]
		\ar[d, xharp, "(*)"]
	&
		\AA^\omega
		\ar[u, xharp]
		\ar[d, xharp, "(*)"]
	\\
		\inverselim \Z[\beta]/\beta^n\Z[\beta]
		\ar[u, xharp]
		\ar[r, "\text{(shift)}"]
	&
		\ar[u, xharp]
		\inverselim \Z[\beta]/\beta^n\Z[\beta]
	\mathrlap,\end{tikzcd}

(shift left is the trick I use)

@tohecz Ah, I thought you are looking for -left to

@percusse I'm not sure what's left to, but I'm sure that this approach works and looks exactly the right way :)

@tohecz

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}[>=left to]
\draw[<->] (0,0) -- (1,1);
\end{tikzpicture}
\end{document}

@AdamLiter Maybe I'll rewrite usebib with expl3 and implement support for the author field.

@percusse well, tikz-cd doesn't seem to be as straightforward in using tikz's native arrows. Anyways, gotta go!

and thanks!

@egreg That would be nice! But there's certainly no need to do it just on my account. I have been meaning to find time to switch to biblatex for the last year, so hopefully it happens sometime soon ...

@PauloCereda How do I test the list's length? I tried if (isList(element) and length(element) == 3) and if (isList(element) and size(element) == 3) and various other random guesses. (Who needs a manual when you can have more fun with zen programming ;-) )

Another day, another beamer blog post: texdev.net/2014/10/13/beamer-overlays-beyond-the-visible

Anyone here some experience with converting tikz to html? What is the best route ? Svg images maybe ?

@Kasper Perhaps use latex + dvisvgm to create an svg file.

cool, thanks guys

@NicolaTalbot element.size() does it. :)

@NicolaTalbot: Try if (isList(element) && element.size() == 3) { :)

How do you guys call a n-tuple with n = 3?

Trio, triplet, triad, trinity? :)

@PauloCereda: triple?

@ChristianHupfer You tell me, I dunno. :)

@PauloCereda: It's even in German 'tripel' ..., ok, almost the same word ;-) (of course it's no original German word, I suppose, it has Latin origin)

@ChristianHupfer In Portuguese, we have trio.

@PauloCereda: trio, that was a German pop group in the early 80ties :D

@PauloCereda triple (adj.) or trio (n.), used same as double/duo. Trio and duo almost always refer to a performing group unless it's used fancifully (like a "trio of chocolate cakes")

@AndrewCashner Ah I see, so triple it is. :) Thank you Andrew (and you too, @Christian). :)

@PauloCereda I forgot, triple can also be a verb

@PauloCereda I suppose in technical math settings where it is possible to have "a duple" you could also have "a triple" as a noun

meant "a triple"

@Andrew: do not worry, it's just for a internal class name. :) I just wanna be fancy with the name. :)

@PauloCereda after that it's quadruple, quintuple, sextuple, etc., so basically just Greek words

@AndrewCashner :)

@PauloCereda Speaking of language, I especially enjoyed this comment (tex.stackexchange.com/questions/205338/…). I can't imagine anyone writing "for the love of God" in an English post here, but somehow in Spanish it didn't seem rude.

@AndrewCashner Indeed! :) My Spanish is terribly rusty, but it's a great comment from Fran. :)

@PauloCereda Maybe he made up his Spanish grammar as he went on. ;-)

good night

@egreg :)

@AndrewCashner Good night! :) Thanks again.

@egreg As long as he doesn't tease @percusse with azulfondo, everything is fine. :)

@PauloCereda Yesterday Estonia-England 1:0; today Malta-Italy 0:1. Not really great scores.

@egreg I wonder if @DavidCarlisle is worried. :)

@egreg: globoesporte.globo.com/futebol/times/santos/noticia/2014/10/… See if you can play the video. :) You'll love the scene.

@PauloCereda New heights in simulation!

@egreg :)
