@HeikoOberdiek ... hand me an award an watch carefully!

7:43 AM

@egreg I am facing a curious situation (\label-\ref mechanism is biting!) ... In case you're around, I'd be glad to describe and may be you have some comments.

8:39 AM

@AlanMunn: I edited your answer.

vveliev

thank you :)

do you know any good reference material about how to create environments? that sort-of emplanes why i should use \surroundwithmdframed , or show alternatives.

8:59 AM

@vveliev The command is defined by mdframed. See documentation.

vveliev

thank you

@AlanMunn Re your starred comment. I presume you know about en.wikipedia.org/wiki/EMac

9:18 AM

@kan I am now. How was your trip home?

9:50 AM

@DavidCarlisle: Is there a license issue with tlxtable? Please see:

@MarcoDaniel ltxtable is not shipped with MikTeX. How to install it? — user4035 3 mins ago

10:14 AM

@egreg Oh! Thanks for asking! It was not very pleasant, after the Railways had messed up the coach numbers for passengers travelling with "Reservation Against Cancellation" tickets...

But, gladly, I am now OK!

I was going to ask you how to do the following best:

I have a file labels.tex with \labels for several theorems, say. I also have, refs.tex with references to these labels. But, now, I want to have two kinds of things: (a) a main file where both references and labels co-exist (not a problem!) but also, (b) have refs.tex alone compile to a pdf where the \ref come out with same values they resolve to in the case (a)...

@egreg Have I got the problem across to you?

@kan Package xr? Or zref-xr?

@egreg Thanks for the tip. I'll take a look!

@egreg I think xr nails it!

How to make the following output more beautiful?

\documentclass[preview,border=12pt,varwidth]{standalone}
\usepackage{amsmath}
\begin{document}
\abovedisplayskip=0pt\relax
\begin{align*}
&&6x^2-30x+36&=0\\
&&6(x^2-5x+6)&=0\\
&&6(x-2)(x-3)&=0\\
x-2&=0 & &\text{or} & x-3&=0\\
x&=2 & &\text{or} & x&=3
\end{align*}
\end{document}

I want to make the spaces on the left and right sides of the word "or" get well balanced.

10:34 AM

@ClickMe I would write a small sentence after the third equation. Something like: Now we have to interpret two cases. So it looks really odd.

@MarcoDaniel Then the code?

@ClickMe Don't use those horrible spaces. There's no need to have alignment at the equals sign in the first three lines, so a gather* environment is what I'd use; just \quad around "or".

@egreg and @MarcoDaniel: I got the solution:-) as follows.

\begin{gather*}
\begin{aligned}
6x^2-30x+36&=0\\
6(x^2-5x+6)&=0\\
6(x-2)(x-3)&=0
\end{aligned}\\
\begin{aligned}
x-2&=0 & &\text{or} & x-3&=0\\
x&=2 & &\text{or} & x&=3
\end{aligned}
\end{gather*}

@ClickMe An implication arrow is missing (for me) ;-)

@MarcoDaniel I don't understand it.

10:43 AM

@egreg: Did I use the wrong English word?

@ClickMe In my course I advice students to teach that doing math is not scribbling down as many symbols as you can. Passages should be connected by words. I can understand a schematic solution, but don't put too much emphasis on it.

@MarcoDaniel No. But I wouldn't use an implication arrow even under physical threat. ;-)

@egreg :-)

@all: OK. But now I have a new problem as follows. There is a space on the left. How to remove it?

\documentclass[preview,border=12pt,varwidth]{standalone}
\usepackage{amsmath}
\begin{document}
\abovedisplayskip=0pt\relax
\begin{gather*}
\begin{aligned}
6x^2-30x+36&=0\\
6(x^2-5x+6)&=0\\
6(x-2)(x-3)&=0
\end{aligned}\\
\begin{aligned}
x-2&=0 & &\text{or} & x-3&=0\\
x&=2 & &\text{or} & x&=3
\end{aligned}
\end{gather*}
\end{document}

@ClickMe Don't use standalone. Use article

@MarcoDaniel I need standalone to create a pseudo screenshot.

10:48 AM

@ClickMe @MarcoDaniel Those passages should mean "this line is equivalent to the next one". That's why alignment at the equals sign is not needed (actually it's wrong, in my opinion).

@ClickMe Then use tabular or array.

@egreg What do you suggest?

@egreg How about this one?

\documentclass[preview,border=12pt,varwidth]{standalone}
\usepackage{amsmath}
\begin{document}
\abovedisplayskip=0pt\relax
\begin{gather*}
6x^2-30x+36=0\\
6(x^2-5x+6)=0\\
6(x-2)(x-3)=0\\
\begin{aligned}
x-2&=0 & &\text{or} & x-3&=0\\
x&=2 & &\text{or} & x&=3
\end{aligned}
\end{gather*}
\end{document}

Here's how I'd do it

\begin{gather*}
6x^2-30x+36=0\\
6(x^2-5x+6)=0\\
6(x-2)(x-3)=0\\
x-2=0 \quad\text{or}\quad x-3=0\\
x=2   \quad\text{or}\quad x=3
\end{gather*}

Sosi

Hi everyone!

10:52 AM

@egreg I see.

\documentclass[preview,border=12pt,varwidth]{standalone}
\usepackage{amsmath}
\begin{document}
\abovedisplayskip=0pt\relax
\begin{gather*}
6x^2-30x+36=0\\
6(x^2-5x+6)=0\\
6(x-2)(x-3)=0\\
x-2=0 \quad \text{or} \quad x-3=0\\
x=2 \quad \text{or} \quad x=3
\end{gather*}
\end{document}

But the output is still strange as follows.

@ClickMe That's a problem with standalone

@ClickMe There is nothing strange. ;-) Run pdfcrop

@MarcoDaniel I don't like pdfcrop, it is not smart enough to trim.

@MarcoDaniel Thanks for the edits to my answer. I learned a lot about your package by cooking up that answer.

@AlanMunn Now you can correct the grammar ;-)

11:02 AM

@AndrewStacey Hi Andrew, yes it spoiled the joke a bit. :)

@ClickMe Than you can try:

Sosi

Guys, I'm using TexMaker to write. Is there anyway for me to visualize how a small change in my text outputs, other than compiling everything (i.e. other than Latex > Latex > BibTex > Latex)?

\documentclass[preview,border=12pt,varwidth=4cm,]{standalone}
\usepackage{amsmath}
\begin{document}
\abovedisplayskip=0pt\relax
\begin{gather*}
6x^2-30x+36=0\\
6(x^2-5x+6)=0\\
6(x-2)(x-3)=0\\
x-2=0 \quad \text{or} \quad x-3=0\\
x=2 \quad \text{or} \quad x=3
\end{gather*}
\end{document}

mdframed, md= Marco Daniel, framed = Marco Daniel's own implementation of a framed package. Mindblown.

Sosi

Often I just want to make a small change, but then I have to wait for the whole thing to compile, which becomes cumbersome after a while

11:03 AM

@MarcoDaniel How did you get the number?

@PauloCereda Did you just realise this now?

@PauloCereda Yes ;-) you can blame Herbert. I wrote the package for my thesis and Herbert wanted that I upload the package.

@ClickMe Try and error. It's a good method ;-)

@MarcoDaniel Oh my ghost.

@AlanMunn Actually, some days ago. :) I do not have a good insight. :)

I have sent an e-mail to the standalone author.

11:05 AM

@MarcoDaniel I blame you. :)

However the new package is christened to xframed

Hey, we could write a TeX game similar to the Pokémon franchise, but instead of Pokémons, we can duel with packages. :)

@ClickMe @MartinScharrer: You got mail ;-)

longtable used bug. It's super effective!

@MarcoDaniel eXtreme framed. <3

@MarcoDaniel I think you should stick with mdframed (unless the new package is totally incompatible with it).

11:09 AM

@MarcoDaniel: I think you should rename it onions.

@AlanMunn No. I am providing a file xframed-mdframed.def which allows the user to load xframed but using all defined mdframed environments as usual.

\usepackage{onions}

That would be awesome.

I think I better shut up now. :)

@PauloCereda You are so creative. For my next project you can choose the name.

Andrew Stacey

@PauloCereda \usepackage{duck,onions} \cook{duck}{onions}

@PauloCereda The package that makes you cry.

11:10 AM

@MarcoDaniel Trust me: don't do this. :)

@AndrewStacey Oh no! :)

@AlanMunn Literally. :)

@Andrew: BTW expect an email from me later on. I have news. :)

Andrew Stacey

@PauloCereda In-tree-guing. I'll look out for it. (*Checks spam fritter ... I mean, filter*)

@egreg Does xr allow documents with include?

@kan Hmm. I really don't know; I never use \include /with Bela Lugosi voice

@Tiina Welcome to the chatroom!

Thanks :)

@Tiina Welcome

12:00 PM

This is like a wonderland

@egreg I think it does! I was afraid, because, it comes from @David and he is punitive: punishing them if they deserved. Since using include is a sin, I was not really sure.

how did they make it, merge the stackXXXX websites together :D

@PauloCereda :-)

I need help to understand the question ;-)

But mister, this is not what I am asking. — Murat Arat 1 min ago

@MarcoDaniel good point ;)

@MarcoDaniel Because of the mister part. :)

@PauloCereda LOL

12:08 PM

I am bitten: I have met this error often and I forgot how I resolved this one: No Counter 0 defined.

Any help?

Holy TeX, when I first read \documentclass{minimal}, my brain glitched and I read \documentclass{nickminaj}. Oh dear.

hei, the article should be inprocedings right, then what about the standard?

I found an example from IEEE, the zip that includes the IEEEtran.bst too, but the example doesn't look the same

did anyone read my article published in the tex community? =)

@egreg yeah some are unbearable

12:23 PM

@Rico Nope :-) Which article?

robjhyndman.com/hyndsight/colors-in-latex/…

@Tiina Sorry. I can't understand your issue? What do you want to achieve?

@MarcoDaniel I added one entry (a standard) in .bib which is an example in IEEEexample.bib, but it was not displayed in the article. I thought the syntax was wrong. but now it seems the only problem is I didn't cite it.... so no problem!

@Rico just joking. Colors in LaTeX don't mean too much for me :)

Is Marc van Dongen deleting answers again?

@percusse What?

@percusse hehe ;) I don't use them too, I was asked to write about it so i did ;)

@MarcoDaniel Somebody was searching for this a few days ago tex.stackexchange.com/a/39299/3235

And then I noticed a few of them vanished too but maybe just house keeping.

@Rico I liked your layout and font selection though. Very nice and comfortable.

That cloud thing is kind of getting in the way though :)

Q: How to deal with the size of the exponential type function's argument?

3:09 PM

Can we reopen this one as OP is still editing the question to formulate his point in a cleaner fashion?

I have the following function in a report of global size 12 : $Q= \rho V c_{p} \left( T -T_{\infty} \right) [ 1-e^{\frac {h A_s}{\rho V c_{p}}t}]$ As one would expect, the exponential function's argument appears very tiny: Is there any way (within the limits of good practice) to deal with t...

3:37 PM

@MarcoDaniel I think the Matlab and Mathematica examples would look great in the mdframed manual.

4:25 PM

@percusse Currently I am fixing some issues. I modified the manual too and I think you are right this is a good example.

David Carlisle

4:42 PM

@MarcoDaniel its LPPL, so shouldn't be a problem.

@DavidCarlisle ... Than it's a bug of MikTeX ;-)

David Carlisle

@MarcoDaniel it's packaged in a slighly unusual way (a single .tex file no dtx/ins so miktex probably didn't notice it existed at all:-)

@DavidCarlisle :-) Maybe you can provide an update ;-) The single tex file contains the material of a dtx file ;-)

LaTeX 3 need a better floating point arithmetic than LaTeX 2.\varepsilon does have

@DominicMichaelis What are we looking for?

thin blue lines

you find them at 6400 % zoom

@DominicMichaelis Just a sec

@DominicMichaelis That's using the pgfmath engine, nothing to do with LaTeX2e :-)

@DominicMichaelis Acroread?

4:59 PM

@DominicMichaelis Also, PDF rounding can be an issue

@percusse yeah adobe reader 10 or 11

SumatraPDF output

here i see blue lines too

@DominicMichaelis Yes. But you don't want them?

nope they just appear by rounding issues. I wan to construct the cantor set in 2 d. I started with a blue square and taking away the mid squares by covering them with white squares

mafp

5:05 PM

@percusse The system asks me to revert to chat, so: What do you think about an informal rule to not close questions during the first 24 hours?

@mafp I would say let's not push users until we get a confirmation from them (or they really act in a noncompromising way)

@DominicMichaelis There are some aliasing issues inherently blocking your way for getting arbitrary precision. You should avoid upsampling/downsampling in the reader rendering.

Set the zoom level to 6001% and zoom to the left upper part you'll see that few blue lines disappear.

@percusse Thanks

@DominicMichaelis if you want to have a sharper rendering you need to add blue rectangles instead of covering them with white which is more tedious to formulat I can imagine

Q: Continuous numbering of custom float with caption package

reopen votes needed:

I defined a custom environment that allows me to define mathematical problem statements and puts them in a box. Since I have quite a few of them in my report, I decided to properly caption them, which also allows me to refer back to the problems with cleveref. Here is my code [1]: \usepackage{x...

Is it possible to remove the "Glossary" headline from glossaries? Seems like nothing I do will remove it. I tried \renewcommand*{\glossarymark}[1]{}

at siunitx how can i change the language ?

@percusse In the great MATLAB command window battle I ended up in the question as the final solution but you ended up being the accepted answer. Go figure. :)

cgnieder

7:49 PM

@DominicMichaelis you mean automatically? Either load the translator package with the right babel language as option or use the language as class option.

I tried ngerman as class option but that didn't work

Now i used Locale=DE

This works as expected:

Silly question - surely tex.stackexchange.com/questions/115280/… is a duplicate?

@LostBrit no idea..

@Tiina maybe that should read "please tell me that <link> is a duplicate"? It just seems to be one of those fundamental questions that must have been answered way back when ...

@LostBrit Well that's what my comment was supposed to suggest. But poor Abdu seems very lost, and Heiko and Svend jumped in to answer. Having some duplicates isn't too bad.

hei, does anyone know that if I have a .bib and it has some string defined in another .bib, how should I bridge them?

@egreg Well in this case it was, but how do you stop people from answering?

Q: split doesn't want to split \left and \right

This is surely a duplicate, instead. :)

In short, I have : \begin{equation} \begin{split} a = & \left | \dfrac{b}{c} \\ & + \dfrac{d}{e} \right | \end{split} \end{equation} and it complains that I want to split \left and \right, if I remove those everything is ok. Please suggest what to do in this case? Thanks, Irakli

@AlanMunn It isn't a trivial table, after all.

And Svend's table is nice.

8:54 PM

@egreg Well it could have warranted an attempt at least, rather than just a picture. That to me is what makes it RTFM.

@AlanMunn ah, young people today :)

@LostBrit Do I sound that grumpy? :)

@AlanMunn no, I checked myself before writing RTFM to that question. Besides, I needed 15 characters.

@LostBrit Good. We really don't like to do that to anyone here; it's what makes the site so friendly.

@egreg it is nice. Booktabs is a work of genius. I'll forgive anyone for an answer that uses it...
