@JosephWright I'm trying to get back into it all, yes! Only seem to have time on the weekends though :(

2:07 AM

@AndrewStacey: I agree with @Jake with his comment about un-deleting your answer. Please.

1 hour later…

Anybody there

Is anyone using the new iOS app? I have to confess I don't understand how to use it. It seems much inferior to the "mobile" website. But maybe I just haven't got the hang of it yet, as the comments on the blog message seem enthusiastic?

4 hours later…

9:29 AM

@Mico: Wanted to thank you for the effort in answering my question about fractions in DanteMT. Unfortunately I never touched LuaLaTeX (never even checked its installation...) and I am also embarassed ;) I kept asking without showing any of the (proprietary) code of the class. Nice 1 of you!

9:56 AM

Hi - What's the easiest way to talk to a TeX.SX member directly? I don't see a private chat option anywhere...

@1010011010 there is no private chat but you can make a new chatroom and invite them to it (or if they have a real name instead of binary digits you can put their name into google and find their email address:-)

@DavidCarlisle I changed my name recently - I can't change it back now. Sorry

@1010011010 click on the **site rooms"" button on the right and theer is a create new button

@1010011010 well you can change it any time but I didn't mean you should, just that it's easier to locate people with real names than fake ones. (although it depends on the name of course not everyone comes on the first google page if you search for their name:-)

Thanks. For somebody who values interactivity I have to say there's room for improvement in the site structure there....

@1010011010 I think there is a discussion on meta somewhere, they consider lack of private channels to be a feature not a lack of feature

10:04 AM

@1010011010 Member-to-member stuff is not encouraged: the network idea is that questions/answers should be 'general' is scope

@1010011010 Mods do have 'direct' communication routes, but for specific purposes

@DavidCarlisle I'd argue that a such barrier of communication is no longer of this time - but each to his own.

@1010011010 yes well it's the price you pay for using a closed system run by a private corporation, we don't get any say in the rules:-)

10:33 AM

@DavidCarlisle I'm a bit confused here. How does the \value command actually work? I defined using \newcommand{<macro>}{\value 5} and inserted the macro to globally set some value but it's constantly yapping about some \@argdef

10:43 AM

@1010011010 it returns the value as a <number> and takes as argument the name of a latex count so \value{equation} is a primutive tex number which you can use as \count6=\value{equation} it doesn't return a printable form. so \value 5 won't do anything useful

@DavidCarlisle What's the go-to solution to assign value 5 to \count6 instantly ? To use \count6=value{5} I'd need \count6 defined.

@1010011010 \count6 5

@1010011010 \count6 is always defined (\count is a Tex primitive)

$ tex '\count6 5 \showthe\count6 \end'
This is TeX, Version 3.1415926 (TeX Live 2013)
> 5.
<*> \count6 5 \showthe\count6
                              \end
?
No pages of output.
Transcript written on texput.log.

@1010011010 ^^^

@DavidCarlisle I think tikz works differently, because it keeps returning: File ended while scanning use of \@argdef.

@1010011010 No, you just used it wrong

Kind of get the impression this won't fly the way I see it.

In my tikzpicture: samples=\count1,

In preamble: \count1 5%

10:56 AM

@1010011010 don't use unallocated count registers unless you know what you are doing:-) odd numbered registers may be set globally at any time by any macro, and count registers 0 to 9 are used by the output routine to hold page number info

@1010011010 back up, say what you are actually trying to do an make an example document in a real question on site....

@DavidCarlisle Will do in a second. I'm just trying to not clutter the front page with trivial questions too much, of which I believe I have plenty.

@1010011010 pah that's only the front page, but this is cluttering up the chat room and taking up space that could be used for @egreg's holiday snaps or discussion of football or cricket.

11:29 AM

Yeah, it's done.

11:39 AM

Hello guys! Long time since I have been here and answered questions, shame!

@1010011010 was away but I see Torbjørn's answered in a comment, see a MWE helps, all the above discussion about count registers was irrelevant:-)

@DavidCarlisle I just don't understand. Since I messed around with this samplesize stuff, I can't use my marginpar macro anymore. That other macro was the actual culprit.

12:31 PM

Hello all

Is @NicolaTalbot online?

12:42 PM

@MarioS.E. she was 9 minutes ago:-) tex.stackexchange.com/users/19862/nicola-talbot

@DavidCarlisle :( I missed her. Well, maybe she comes back

@DavidCarlisle Is it mother's day in the UK too?

Don't let the commercialization consume you!! It's not yet too late!!

12:56 PM

@MarioS.E. Yes, I am now. (I went off to have some lunch.)

@MarioS.E. No, it's usually during March in the UK

@NicolaTalbot It was last week in Portugal, and today in Peru

@MarioS.E. Happy mother's day to all Peruvian mothers :-)

@NicolaTalbot :) hehehehe

@NicolaTalbot I was thinking about posting a question, but then I had a feeling that I was probably just missing something: I'm using your AMAZING glossaries package along with scrbook. The thing is that when I print any glossary (I'm using both acronyms and Nomenclature) I get a little less space from the top margin to the "List of Acronyms/Nomenclature" title than the regular chapters (i.e., List of Figures, Table of Contents, Foreword, etc.) Have you come up with something like this?

@MarioS.E. I'm glad you like it! I have a feeling there was a question posted some time ago that had something similar. I think it had something to do with \tableofcontents etc being modified so that they weren't using \chapter* so they didn't quite match. Try adding \chapter*{Sample} after \printglossary and see how it compares with the front matter.

@NicolaTalbot Well, actually "foreword" it's an \addchap. Both the Foreword and the List of Tables are correctly aligned, the only ones that are not are the List of Acronyms (\printnoidxglossary[type=\acronymtype,style=long,title={List of Acronyms},toctitle={List of Acronyms}]) and List of Nomenclature (\printnoidxglossary[type=nomenclature,style=long,sort=use,title={List of Nomenclature},toctitle={List of Nomenclature}])

1:08 PM

@WillRobertson Thanks for your answer and for your work. Very much appreciated.

@NicolaTalbot I think I found the problem!! hehehehehehe I was setting the printglossary within \begin{singlespacing} ... \end{singlespacing}

@MarioS.E. That would mess with the spacing :-)

@NicolaTalbot follow-up question then: what's the right way to space the entries in single spacing?

@MarioS.E. Depends on the style.

I'm using style=long

1:18 PM

Relating to this question : tex.stackexchange.com/questions/176533/… I am quite surprised that things like $\alpha$ is not interpreted on tex.stackexchange. LaTeX is parsed on mathematics or physics.stackexchange but not on tex.stackexchange ?

@MarioS.E. In which case we need to ask @DavidCarlisle what's the right way of single-spacing a longtable ;-) I think just doing \renewcommand{\glossarypreamble}{\singlespacing} ought to work.

Q: Why doesn't maths render as maths?

On some other SE sites, code in between dollar signs gets rendered as mathematics (using MathJaX, I believe). This doesn't seem to work here? Why not? And how do I get round it?

@Vincent Deliberate: we don't want that

@Vincent You probably see that \alpha as a symbol (with an extension installed), while all of the 'regulars' here will see the TeX code :-)

@TorbjørnT. Ok, I understand now !

@NicolaTalbot Yes!!!! Perfect! thank you very much!

1:22 PM

@MarioS.E. Great :-)

@NicolaTalbot Taking advantage that you are here, one last question: For nomenclature, is it better to use

\newglossaryentry{ohm}{name=Ohm,type=nomenclature,symbol={\ensuremath{\Omega}},‌description=Unit of electrical resistance}

over `\newglossaryentry{ohm}{name={\ensuremath{\Omega}},type=nomenclature,description‌=Unit of electrical resistance}

@NicolaTalbot I mean, should I create my own style where the entries are sorted by their symbol rather by their name, or should I just change use the name with the symbol?

@MarioS.E. I think it depends on the document.

Are readers more likely to want to look up "Ohm" or "\ensuremath{\Omega}"?

At the end of the day, the glossary (like an index) is there to help the reader, so you have to put yourself in the place of the reader and try to think like someone who isn't familiar with the document.

1:43 PM

@NicolaTalbot Ok, based on that I think they'll be looking for "\ensuremath{\Omega}"

1:55 PM

Hello everyone

Can I define a variable that can be used to decide whether or not \textbf outputs the bold text or just standard text?

I have ~30 words I maybe want to have bolded. In short, is there an easy way to switch on and off the bolding?

@Argo Create a new command for those words, and modify the command depending on whether you want bolding or not.

Hmm that's what I thought. Can't I just redefine \textbf{} ?

Is it normal that the options textwidth and xrightmargin seem to have no effect when using the multicolumn option in a lstlisting ? If yes, how can I change the width of my columns ?

@Argo Perhaps, but that sounds like a bad idea to me.

@Vincent The manual does say The multicolumn option is known to fail with some keys., so perhaps that includes margin settings.

2:20 PM

@TorbjørnT. And how can I find a hack to try to redefine that manually ? (I try to solve this problem tex.stackexchange.com/questions/176533/… for 3 hours now and I haven't made any progress)

3:15 PM

@Vincent No idea I'm afraid.

How can I set a newlength to the height of the \tiny font ?

@TorbjørnT. I am making progress with ugly hacks on tcolorbox ;-)

LaTeX3 project question for the audience: does there yet exist a user guide / user manual for LaTeX3 (along the lines of The LaTeX Companion)? In an attempt to really understand the problems and motives behind LaTeX3 concepts (specifically templating), I've written something of a rather long narrative. Am I duplicating effort?

@SeanAllred No guide as such: needs working code first

@SeanAllred Note issues with template system: designed in mid-1990s when original plans were too ambitious. Now, that's no longer the case and we are hoping to have another go at 'LDB', probably in the guise of 'LaTeX Style Sheets'

@DavidCarlisle Any comment on that?

Or (timezone dependent!) @WillRobertson?

@JosephWright Not necessarily. History teaches us that goals are met when goals are set—a user guide can act as a collection of these goals. Does any such list already exist?

@JosephWright What I'm seeing (or rather, not seeing from this side of the fence) is a set of ideals that LaTeX3 wishes to attain. For F/OSS this is often difficult to come up with (since nobody would want to step on toes), but it's very helpful to have.

@JosephWright (Thanks for you comments at any rate :))

@SeanAllred There are some things in latex-project.org/papers, plus Frank has other docs

@SeanAllred I can forward a big list of e-mails if you like!

3:22 PM

@JosephWright Haha! You've actually already forwarded me those. I made it about half-way through before my thesis took over my life; perhaps it's high time to pick them up again.

@SeanAllred Summary: the idea is to have a way of describing document design that is sufficiently flexible and rich to cover the use cases for LaTeX while also working with the way TeX 'does stuff'. Discussion in the past predates e.g. CSS but also recognises the differences in requirements (for example, pages!).

@SeanAllred Current thinking in my mind: some form of CSS-inspired (but probably not CSS-like) syntax to describe design and relationship between elements

@SeanAllred Frank wants use cases to model from rather than writing code first and finding it does not work for a good subset

@JosephWright Were such a syntax implemented, would it be TeX-interpreted?

@SeanAllred I think I've mentioned in the past some of the issues with templates

@SeanAllred Yes

@SeanAllred Current 'base' requirement is pdfTeX 1.40

@JosephWright It seems that Frank and I would have similar thoughts on how to tackle the problem. I always find that when I dive head-first into code, I discover I've written a solution to a question nobody asked.

@SeanAllred He's got lots of experience!

Then again, nowadays I've got quite a bit myself despite having no formal computing background

E.g. currently rewriting build scripts in Lua :-)

3:27 PM

@JosephWright A lot of experience you pick up 'on the job' as it were.

@JosephWright Ooh! Ooh! Build scripts for what?

@SeanAllred LaTeX3 releases

@SeanAllred Currently we use a mix of Makescripts on *nix and batch files on Windows

@SeanAllred Plan is to have one set of scripts: minimise mess-ups when I do a release!

@JosephWright I can see where bringing the two together under a common umbrella would simplify things :)

@SeanAllred Yes: Frank recently had to rewrite the LaTeX2e ones (as Windows batch files), and I'm looking to pick up some of what he did there in terms of 'isolating' the code while testing, etc. Also looking to use one 'master' file plus small add-ons rather than the current copy-paste situation.

@SeanAllred Well, I've had to code around Lua's platform-neutrality a bit :-)

@JosephWright As with any lightweight language. Python has similar… quirks. It can get in the way when you just want it done this way.

@SeanAllred Not too much of an issue: detect the language then use bits of our existing scripts via os.execute :-)

Will probably check in a first version later today

I need @DavidCarlisle to test on Cygwin

3:33 PM

@JosephWright For me at least, it bothers me when I have to bop out to the shell like that. A necessary evil, though.

@SeanAllred Well in a buildscript it's expected anyway

@SeanAllred Somewhere we need to run TeX!

@JosephWright I look forward to seeing it! A couple of my students did a introductory project on Lua a few weeks ago; it'd be cool to see a real use case that isn't overly gigantic. (Some games are built with Lua.)

@JosephWright Well see that's when you write a function run_tex_with_params(params) that lets you hide from the shell :)

@SeanAllred Currently about 450 lines for the 'master' file with around 50 in the one config file I've created

@JosephWright Big, but definitely manageable. Are you just waiting on David's test before you check in?

@JosephWright Whelp, I gotta run. I'll think on the LaTeX Style Sheets idea on my 2hr+ drive home (:() and compare my thoughts to the email thread and any other resources I can get my hands on. Thanks for the chat!

@SeanAllred No, I'll check in once I have the functionality working at my end, then see how he gets on

4:01 PM

@JosephWright just got back:-)

@JosephWright something like that

@MarioS.E. I hope not (or I forgot:-)

@NicolaTalbot tables are not spaced at all (there is no space between the rows) you can use (or not) \arraystretch as for a normal tabular

I'm getting a strange error when using pageref

I have a bunch of labels to included pdfs (\includepdf) and references to those

All of them work just fine, except the last one.

@DavidCarlisle Phew

Here's the source:

Uddrag ses i bilag på side~\pageref{SO13}.

And here's the error:

4:39 PM

@DavidCarlisle Seems like inserting \singlespacing before the longtable did the trick.

@DavidCarlisle Back from visit to my sister: her elder son had his First Communion today. But just for the intermission during Juve's game. ;-)

@NicolaTalbot If you'd have redefined \doublespacing to be \LaTeXError{don't mess up my document}{} you wouldn't have needed \singlespacing

@DavidCarlisle It wasn't me using it :-P

@NicolaTalbot I'm sure not:-)

@DavidCarlisle I was going to remark that I hadn't used double-spacing in earnest since my PhD thesis, but I've just remembered that I had to use double-spacing or one-half-spacing in all my creative writing manuscripts. (It being a requirement of literary agents, fiction publishers, etc.) I can now get to format my novel according to my own requirements. (So I won't have any excuse if there are any formatting issues!)

5:08 PM

@TorbjørnT. Finally I got the solution (still need to be improved, but it is a good basis): tex.stackexchange.com/questions/176533/…

How could this many issues be reported?

^^^ unanswered longtable test files extracted from gnats reports going back to 1995:(

@DavidCarlisle :-)

@JosephWright are you on the texlive list?

5:47 PM

How sweet is a goal at 3 seconds from the final whistle. :D

3 hours later…

8:30 PM

@DavidCarlisle On most of them

@JosephWright I was just going to ask if you'd noticed the xindy thread, although Heiko seems to have sorted it

8:49 PM

@JosephWright 50 new test files for longtable this weekend:-)

Gonzalo report: 622 points to the goal!

@egreg 3 or 4 days, presumably :)

@tohecz I'd say three. :)

@egreg two ticks? quite likely :) How are you, btw?

@egreg If he tried a bit harder he could do it in two:-)

8:59 PM

@tohecz I'm fine, thanks; ate too much at my sister's. :)

@egreg ah those invitations :) How many courses did you get?

@tohecz Not a formal meal, just many things around.

@egreg ah ok

@egreg @Paulo Oh, I keep forgetting to tell! I am going to Queen's university, Kingston for my graduate school...

@kan Cool! Congrats, have fun in Canada. :)

9:11 PM

@PauloCereda Thanks! Looking forward to it.

@DavidCarlisle Maybe only one, if he gets 800+ like yesterday.

@kan It's a bit colder than India. ;-)

@egreg Yeah! Only just a bit on the off side; like -20 or sth...

:-)

@kan Just forget the –

@egreg And, you're in the pleasant part of India...

Though, they don't speak French...

@kan It's a bit more difficult when in full summer you have 10 degrees. ;-)

9:23 PM

@egreg: but there are mooses! :)

@PauloCereda Hi! How do you do? :)

@tohecz Things are not good at the moment, sadly. I'm terribly sick, with lots and lots of work and a code to write I don't even know how to start. :( But anyway. And you, buddy?

9:40 PM

@PauloCereda I'm fine. I spent two days walking in the Czech-Austrian countryside and two days hardworking, so I'm pretty tired at the moment.

10:02 PM

@PauloCereda I hope you'll get better, pal!

10:17 PM

whoever downvoted this, why?? I can understand vim users downvoting my emacs answers, but I'm a bit bemused by this one. — David Carlisle 20 secs ago

@PauloCereda ^^

Peek-a-boo. I wonder: what does this chat do? Edit: Ok, so enter equals submit. Got it. =P

I'm just browsing the website and thought I'd check out what this chat is. And since I'm here, this seems like a nice place to ask: If I edit a question to which people have already replied, will they be notified, or do I have to leave a comment for each answer?

@eiterorm they won't be notified

10:33 PM

Ok. Good to know. Thanks.

10:54 PM

Hi

I have latex file when I want to view pdf (compile it) it said "file not found"
what is the reason ?

@barznjy you need to give some clues, have you run pdflatex on the file, otherwiise there is no pdf to view

I do the following procedure:
F6 then F11 then F6 then F6 then F7

I am using TexMaker editor

all steps looks fine, but when I want to view PDF i.e. F7 it give me that message

@barznjy Those key bindings are editor specific, they could do anything, I've never used that editor, so cant help:-)

@David Thanks

@barznjy but step back before you can view the pdf you need to make it, so in the pdflatex step either it makes a pdf or it will have made an error message. so if the pdf viewer can't find a pdf you should have an error in the log from the step before

11:08 PM

@David actually I have one warning message, which is Foreign command\...

@tohecz Thank you, my friend. :)

@DavidCarlisle Not me. :)

@PauloCereda It's probably egreg he's well known for liking \left\right

ackage amsmath Warning: Foreign command \atopwithdelims;
(amsmath) \frac or \genfrac should be used instead
(amsmath) on input line 168.

@barznjy that's just a mild slap on the wrist for using tex primitive syntax instead of the correct amsmath commands, it doesn't stop the pdf being made
