@PauloCereda Is there anything that can be tested? Happy to try things out on my end…
 
 
3 hours later…
@IamwhoIsayIam Must I think be a 'local issue'
 
7:28 AM
@JosephWright @JosephWright: Yes. It is a local issue. Someone blocked imgur.com for unknown reason. :-)
I have removed my question on meta.

Q: Comma in math mode

TarassIn some countries one use comma as decimal separator instead of a dot. I ususally use: %%%% Une vrai virgule pour les décimaux \DeclareMathSymbol{@}{\mathord}{letters}{"3B} and $3@2$ to obtain 3,2 instead of $3,2$ that gives 3, 2 <- a uggly useless space after comma I just find this : \math...

We've been asked this before: anyone?
 
@TorbjørnT. No, I'm thinking of something else
 
@JosephWright Ah, ok, sorry.
 
@TorbjørnT. I'm sure we've had a simple solution to allow the spacing to be correct
@TorbjørnT. Ah, someone found it:

Q: Space after comma in units package

ThomasI have a problem with using the units package. In my thesis I used it sometimes in math environment, sometimes not. Now I realized that there is an addition space after the comma in math mode. I think this is a problem of European and American writing of decimal comma and decimal point. Can you ...

 
9:54 AM
@egreg I can only assume you've choked on your morning coffee as I expected to see a 1000 line polemic on the evils of \left :-) tex.stackexchange.com/questions/173717/…
 
10:09 AM
@DavidCarlisle The issue has already been discussed and the answer tells not to use them. ;-)
 
11:01 AM
@WillRobertson Actually, I'm rewriting everything from scratch since @David has the unique ability of breaking others' code. :)
On a more serious note, I'm writing some helper code in Lua in order to make our lives easier. :)
 
@PauloCereda Cool
 
@JosephWright I'm weird. I don't fix stuff, I rewrite stuff. :)
 
@PauloCereda What's the code for?
 
@JosephWright Unit testing, basically. The idea is to have a couple of "methods" (can't remember the exact Lua name for it) that help us analyze output and internals. I'm not inside the lion's mouth yet, but I'm getting there.
@egreg: any good game today on TV?
 
@PauloCereda world snooker championships in Sheffield?
 
11:17 AM
@DavidCarlisle Yup
@DavidCarlisle Good match between Robertson and Allen
 
11:28 AM
@DavidCarlisle BBC broadcast?
 
@PauloCereda Of course
@PauloCereda Can't beat Auntie
 
@PauloCereda yes always bbc and always in Sheffield, don't trust dodgy foreign cities to build the required buildings in time each year:-)
 
@JosephWright I don't have BBC. :(
 
@DavidCarlisle You want \DeclareDocumentCommand { \NewDocumentCommand } { > { \CheckSingleToken } +m +m +m }, I think
@PauloCereda :-(
 
@JosephWright It's a pitty. I'd give away all CNN channels by just one BBC.
 
11:34 AM
@JosephWright anything to make Peter Grill happy:-)
@PauloCereda surely you can find a proxy that lets you er, seem to be in the UK?
 
@DavidCarlisle Ah yes. :) But I'd like to watch it in my living room. :)
 
@PauloCereda carry your tablet:-)
 
@DavidCarlisle You have a point. :)
That's one of the reasons I want to get either an Apple TV or a Chromecast.
 
@PauloCereda or visit the UK
 
@DavidCarlisle I can visit you. :)
 
11:37 AM
@PauloCereda then you can either work through 15 year old bug reports, or play with lego
 
@DavidCarlisle Lego it is. :)
@David: so uncle Joseph never lent his PS3 to M?
 
looks like someone wants the new latex release: tex.stackexchange.com/questions/173754/…
@JosephWright can you use the email of the user ^^^ or is that an abuse of your powers? It might be good to send him a stripped showkeys.sty and asking him to test...
@JosephWright actually I'll just comment suggesting he sends the doc to me
 
12:10 PM
@PauloCereda No, tomorrow is the day: we play Sassuolo.

Q: Does a dot or period (.) get italicized or capitalized?

Awal GargWhen we italicize text with the dot (.) or period symbol, does it actually change the (.). So, is . different from . Can anyone tell which of them is italicized? And same way for capitalization. . different from . Does it matters? P.S. I am not sure if I should ask this here, ...

 
@DavidCarlisle Saw that
 
12:58 PM
Morning
 
@AwalGarg if you'd asked here it could be answered (italicised:yes, capitalised:perhaps) but if you ask in general there is no answer, it depends on the system
@hftf it's 2 in the afternoon, but hello:-)
 
I'm just wondering if it's appropriate/correct to add my own solution (under Update 2) as an answer here? I already awarded the bounty so it's not about that.

Q: Why does PGF/TikZ 3.0 draw my simple layered graph as non-planar by default?

hftfI have two questions: If I’m reading §30.4 “Crossing Minimization” of the PGF/TikZ 3.0 manual correctly, the layered graph drawing algorithm should have crossing minimization enabled by default. So why doesn’t the algorithm automatically choose a planar embedding for this graph? What is the bes...

The reason I'm not sure is it doesn't seem significantly different from the second answer.
 
@hftf if you think an answer helps someone who lands there by search, never hurts to give a self-answer
 
@DavidCarlisle Alright, thanks! (And good afternoon, then :p)
 
 
2 hours later…
3:16 PM
I need a green tick to be palindrome. I'll look for a question answered by DPC.
 
@egreg It's a shame we've not managed to get SPQR to join :-)
@egreg Perhaps he'll ask a question for you to answer ;-)
 
@JosephWright That would be nice from him! So it's impossible. ;-)
 
3:30 PM
@egreg I could downvote a few of yours if it would help
 
3:43 PM
@DavidCarlisle I remember now why xparse doesn't currently check for single tokens! There are a few xparse-related things in my mind, so perhaps a bit of revision is in order.
 
@JosephWright example?
 
@DavidCarlisle The reason we don't currently have a test is that the 'processors' code isn't really suited to it: it happens in the 'wrong' place and can't for example 'bail out'.
All fixable, of course
 
Hello everyone
 
@Argo hi
@JosephWright ah I thought you meant a use case where you wanted multiple tokens
 
I'm getting this strange error when typesetting:

pdfTeX error: pdflatex (file ./oxidation.pdf): xpdf: reading PDF image failed
 
3:48 PM
@Argo well it means the file's there but pdflatex thinks it hasn't permision to read it or can't read it. Can you view that pdf in your pdf viewer, or has it got corrupted?
 
There are only jpg files I can open just fine
 
@DavidCarlisle Ah: no :-)
 
@Argo only jpg? are you not doing \includegraphics{oxidation.pdf} to include a pdf?
 
Hmm I'll try making pdfs instead
 
@Argo It's hard to help if you don't show code (preferably with a question on site) but I can't guess from your fragments of information what you are trying to do. If you ask latex to include a file which isn't there, it won't work:-)
 
4:00 PM
It's a simple \includegraphics command
The document is part of a larger one using the subfile package
 
@Argo but you're speaking in riddles. If I have a file oxidation.pdf i'd expect \includegraphics{oxidation.pdf} to work, and if I haven't such a file, it won't work.
 
oxidation.pdf does not exist
oxidation.tex is the document
I get the error, no pdf is created
 
@Argo well pdfTeX error: pdflatex (file ./oxidation.pdf): xpdf: reading PDF image failed indicates that pdftex is trying to read it not write it. at least, it looks that way, you haven't shown the full error message, so again I'm guessing.
 
Hello everybody! Does anyone know if there is an easier method to get the kerning between two letters, than saving both in a box and then subtracting the two chars respectively?
 
@DavidCarlisle Riddle me that, Batman. :)
 
@HenriMenke look in the font metrics?
 
@DavidCarlisle How can I read these out using TeX? In my use case I want to get the kern between "T" and "w".
 
@HenriMenke you have to be careful with that as the difference in with between fi and {f}{i} is due to ligature not kern
@HenriMenke you can't read them from tex:-) (probably can in luatex) doing what you said is the best you can do
 
@HenriMenke Here's the kerning pairs starting with T in cmr10
(CHARACTER C T
   (CHARWD R 0.722224)
   (CHARHT R 0.683332)
   (COMMENT
      (KRN C y R -0.027779)
      (KRN C e R -0.083334)
      (KRN C o R -0.083334)
      (KRN C r R -0.083334)
      (KRN C a R -0.083334)
      (KRN C A R -0.083334)
      (KRN C u R -0.083334)
      )
   )
The unit is 10pt
 
@DavidCarlisle Thank you very much!
 
4:10 PM
@HenriMenke see @egreg's doing what I said (as usual:-) that is running tftopl on the tfm file
 
@HenriMenke I did tftopl cmr10 | less
 
@egreg You predicted my question :-)
@egreg Thank you too!
 
@HenriMenke tftopl is kind enough to add as comments the ligatures and kerns pertaining to a character
 
@egreg funny go for months without mentioning tftopl then twice in two minutes:-) tex.stackexchange.com/questions/173806/…
 
Alright found the solution
I had an image called oxidation
The file was called oxidation.tex
 
4:21 PM
@Argo that figures:-)
 
Yeah
pdtex was looking for itself
 
@A.Ellett \begingroup\edef\x{\endgroup is one of @egreg's favourite tricks
 
@DavidCarlisle And Heiko's
 
@egreg Was just about to say that!

Q: How should I type author names in a bib file?

Juan A. NavarroCan someone please explain in a clear and concise way how am I supposed to enter the names of authors in a BibTeX file? I have entries with something like @article{someid, author = {Juan A. Navarro P\'erez, Ra\'ul de la Garza and Andr\'es Espinoza}, ... but somehow the output seems kind...

Does Vanden's answer here need editing to be more 'canonical' (he's not been seen since 2012, so can't really ask him!)
 
5:15 PM
@JosephWright when you told me you're with a team actually debugging beamer, what should we expect as an outcome?
 
This is funny! In this question tex.stackexchange.com/q/173810/3954 some user provides the same non-valid answer as I initially did (then I provided an answer meeting the OP's requirement); when I comment this to him in his answer, he edits his answer to provide the exact same solution (using \raisebox) as I had already done.
 
@GonzaloMedina you've got a clone! :-o
@GonzaloMedina Needed to say, on many SE sites, he would be at -4 or more for such behaviour ...
 
@tohecz so it seems!
@tohecz I was tempted to downvote, but I reserve my downvotes for more serious issues.
 
@GonzaloMedina but he's deleted it now:-)
 
@DavidCarlisle Then everything is OK. I wouldn't even mind had he explained that he was taking the same idea as in my answer....
Now that I see you here, @DavidCarlisle and @tohecz, do you know of any disastrous consequences of using the abhomination ` \\ ` followed by \par? I mean, not the underfull \hboxes that it will cause nor the ugly separation between paragraphs, but really disastrous effects in a document.
 
5:37 PM
@GonzaloMedina An empty page maybe, in certain circumstances, but I'm not sure, @David is certainly more experienced in what happens with `\` at a page break.
 
@GonzaloMedina it makes a "white" line so it looks a bit like vertical space but actually it's an hbox of full width, and in particular it won't be discarded at a page break and will mess up latex's attempts to merge space between evironments (addvspace)
 
@DavidCarlisle But will this undesired effect with \addvspace be a consequence of using the bad combination before the environments?
 
@GonzaloMedina yes any effects are pretty local to the place \\ is used, t doesn't have any global effects
 
@DavidCarlisle I see. So if ` \\ \par` is only used between "normal" text paragraphs no real disasters will occur?
 
@GonzaloMedina yes you'll get really bad page breaks, with the start of the paragraph after the break having a spurious white line above it
 
5:52 PM
@DavidCarlisle Indeed! Thanks.
 
@JosephWright (and others) What should we do with this one?
 
@egreg Been deleted
 
@JosephWright I didn't realize it. It was still open and I had to go out.
 
6:13 PM
I'm thinking of buying Knuth a bunch of beer for his next birthday
I f***ing love (la)tex
 
@Argo Cool! :) Sadly, most users love f****ing LaTeX and its way of doing things. :)
 
I'm about to finish this large document (~80-100 pages) together with a friend
(Chemistry, for those interested)
Subfiles just works
References just works
Numbering of everything just works
Even at 80 pages
 
@Argo Could you edit that, please
 
@JosephWright I put some asterisks. Am I safe? :)
 
@PauloCereda Yes, that's OK
 
6:18 PM
@JosephWright <3
 
Sorry, it's too late now
 
@Argo OK, I've done it then
 
Thanks
 
@Argo Which area?
 
@JosephWright Regex replacement complete. :)
@JosephWright Exploding things, hopefully. :)
 
6:19 PM
Organic
 
@Argo Total synthesis?
 
Not quite, I'm still in highschool (19 years old). Exam project though, so we made a synthesis & analysis of vanillin from eugenol
 
@Argo Ah
@Argo Sort-of, though
@Argo LaTeX's relatively rare pre-university
 
Yeah it's only me and a mate who's using it in my class. I discovered it last year and after reading a bit, it seemed to be the de-facto way of writing academic stuff. Since my plan studying chemistry at uni I figured it was a good idea to start using it.
 
@Argo :-)
@Argo You'll be in a minority in chemistry
@Argo I'm regarded as something of a nutcase for not using Word
 
6:25 PM
ahah @JosephWright that's also the point not in chemistry...
 
@JosephWright Sure it's just for that? ;-)
 
@GonzaloMedina Well no, but ...
 
@JosephWright Marco is already reading the TeXbook to his son. :)
 
I've made my last long (+20 pages) document in word. It's a complete nightmare.
I'm pretty much ready to laugh in silence at my classmates who will be spending hours tomorrow assembling 20 different parts of .docx made with different versions of MS Word to provide maximum incompatibility as well as manually fixing numbering of section, tables, figures, equations, footnotes, font, crossreferences, bibliography, table of contents, table of figures and all that jazz. Ah yes, tomorrow is going to be a good day when I can typeset my document twice and be done with it.
 
6:49 PM
@Argo It'd have been faster for them to transcript it into LaTeX...
 
It's probably a bit too late for them now
 
 
1 hour later…
8:07 PM
is it possible to automatically assign \insertsection for the frametitle?
 
@PauloCereda and teaching him to use emacs I hope
 
@PauloCereda Given the Knuth's writing style, The TeXbook makes a perfect goodnight fairy-tale :)

@egreg so who did you get to downvote your listings answer? :-)
 
@DavidCarlisle I don't know; a comment says it makes an invalid .sty file, which I don't believe to.
 
@egreg convenient for you though:-)
 
@DavidCarlisle But it didn't matter: I got the +2 just a few hours later.
@DavidCarlisle I'm in a 2-5 cycle.
 
@egreg oh I though you were out of parity for the palindrome. I used to be in a palindrome cycle but then another vim user downvoted my emacs answer and pushed me out:(
 
9:04 PM
@DavidCarlisle In three months I'll be out too. ;-) Well I just need to go in a 3-8 cycle, so I can downvote two answers. I have some ideas about which ones. ;-)
 
 
1 hour later…
10:19 PM
@DavidCarlisle This will give his kid nightmares. :)
@tohecz LOL
 
10:47 PM
@PauloCereda No, he will get asleep and dream of boxes and glue.
 
@egreg ooh! :)
 
@PauloCereda And count penalties and demerits, when he's not able to sleep.
 
@egreg \stepcounter{sheep} :)
 
@PauloCereda That's too easy! \advance\sheepcount\@ne
 
@egreg We should encourage @Nicola to write a TeX book for children. :)
 
10:50 PM
Or with modern methods, \int_gincr:N \g_sleep_sheep_int
 
@egreg L3-sheep. :)
 
@egreg \def\sheep{\sheep}\sheep keeps them entertained for hours

@DavidCarlisle \def\sheep{\typeout{A sheep}\sheep}\sheep graciously fills up the disk.
