Is there a vertical version of \Leftrightarrow available?

@Szabolcs palatino + mathpazo

Oh, yes, pxfonts package too!

Yes, apparently newpx is the latest package tex.stackexchange.com/a/119549

\Updownarrow---should have been obvious.

Q: How to iterate through all user-defined control-words?

\documentclass[preview,border=12pt,varwidth]{standalone} \usepackage{pgffor} \def\Person#1{% \ifcsname#1\endcsname \else \expandafter\def\csname #1\endcsname{#1}% \fi \csname#1\endcsname } \begin{document} \Person{Alan} took a shower when \Person{Batman} was cooki...

@AlanMunn, @DavidCarlisle and @egreg (and possibly @Batman). ^^

:)

12:35 AM

@PauloCereda jfbu's answer has too many \expandafter's

@egreg uh-oh.

@egreg: tex.stackexchange.com/search?q=user%3A4427+score%3A0 :)

@PauloCereda Serial voting reversed?

@PauloCereda Now a full fledged LaTeX3 version has appeared.

12:51 AM

@egreg I fixed it. :)

@egreg Very nice!

2 hours later…

3:17 AM

@StephanLehmke Your recent color answers seem to be spot-on!

5 hours later…

8:02 AM

@AlanMunn Nice, isn't it? I had more or less this hack in DocScape since 2006. So it wasn't much of a hassle to adapt the code.

8:15 AM

We'll have another package on the launchpad site soon.

@egreg a l3seq answer is missing ;-)

isn't \texttt suppose to allow one to make section name verbatim? When I write

\subsection{\texttt{invlaplace(exp((a*s)^(1/2)), s, t)}}

I still get an error
<inserted text>
$
l.18 ...exttt{invlaplace(exp((a*s)^(1/2)), s, t)}}

?

I was following this tex.stackexchange.com/questions/83893/verbatim-inside-a-command

I used the other method shown, and this worked:

\cprotect\subsection{\verb|invlaplace(exp((a*s)^(1/2)), s, t)|}

but strange that \texttt did not work, as it said it is supposed to.

8:35 AM

@Nasser I guess the first error is ! Missing $ inserted.

You are using ^ outside the mathmode. If you want to print it, you must escape the symbol:

\documentclass{article}

\begin{document}
\tableofcontents
\section{foo}
\subsection{\texttt{invlaplace(exp((a*s)\^{}(1/2)), s, t)}}
\end{document}

2 hours later…

10:39 AM

Very interesting and old issue: tex.stackexchange.com/questions/145309/footnote-index -- I am wondering that there is no solution.

@MarcoDaniel There is one! ;-)

@Nasser That could depend on your font settings.

@egreg Oh. I missed that ;-)

11:12 AM

@MarcoDaniel Unsolvable? ;-)

11:28 AM

@JosephWright I just got the siunitx badge: (probably mostly due to dcolumn answers:-)

11:56 AM

@PauloCereda I got “Serial upvoting reversed”.

@egreg Oh no!

@egreg: I'm so sorry, it was probably because of me. :(

@PauloCereda I think so. You don't need to. Or do it one a day, like prescriptions. ;-)

@egreg Plan B: start serial downvoting David. :)

12:21 PM

@egreg such simple?

12:50 PM

How can I find what the styling is of the theoremstyles of the amsthm package ?

1:15 PM

Perhaps you should have asked your publisher or read the author guide (if available) before inserting all the forbidden stuff. — Thorsten Donig 3 mins ago

Stating the obvious isn't particularly helpful...

1:26 PM

@MarcoDaniel When you know the reason, yes. ;-)

1:56 PM

@PauloCereda Your gif looks at me ;-)

@MarcoDaniel It keeps looking. :)

I wonder why an edit to an answer to a question which was closed as a duplicate two years ago gets approved...

tex.stackexchange.com/posts/37583/revisions

What else will happen now the question has been pulled up...

@StephanLehmke This question has a lot of views. So for me such question can also be improved.

@MarcoDaniel Wouldn't it be better to improve the question it is a duplicate of? If the answer which was improved here is unique to this question maybe it should be migrated to the other question?

1 hour later…

3:16 PM

Hello I have a question

how do I do the numbering like here:

user image

How do I place the number (2) on the left ?

@user43418 Add the leqno option to the document class.

@TorbjørnT. Thank you

@MarcoDaniel You are indeed right. The closed question not only seems the more popular one, but also the answers seem to be more sophisticated and helpful than those of the question it is supposed to be a duplicate of. This looks like an undesirable inconsistency to me, especially as it is probably a common problem for users. Could some moderator please look into this? Maybe one could merge the questions somehow? @JosephWright @stefankottwitz

1 hour later…

4:42 PM

@StephanLehmke You called?

4:56 PM

I guess an ex cathedra answer is required for tex.stackexchange.com/questions/145335/…, so one of the team will get some free rep :-)

5:24 PM

@JosephWright The following questions look slightly askew:

13

Q: LaTeX figures side by side

Possible Duplicate: Two figures side by side I want to place 2 images side by side in LaTeX. I have 2 .png files and I don't understand how to do it in LaTeX. I have tried many ways but could not get a good result.

graphics floats positioning

Q: Two figures side by side

How can I put two figures side-by-side? Not two sub-figures, but two actual figures with separate "Fig.: bla bla" captions. A figure is supposed to spread over the entire text width, but I have two figures which are narrow and long, and I need to save the space in order to withstand the pages li...

floats captions subfloats

@StephanLehmke What's up?

I was just told the following (by someone handling the LaTeX issues for a journal):

The first is closed as duplicate of the second, but the first has about 10x the views and apparently better answers. Shouldn't one get them together somehow?

@StephanLehmke Comes down to the question of whether we want to merge things. Generally the feeling has been 'no'. Ask about it on meta.

keep in mind that you can't change margins, font sizes and other
settings provided by LaTeX Author Package for the publications in IMS
journal Annals of Applied Statistics. In that case your changes will
be dropped. So, such packages as changepage better not use.

I commented out changepage, and it still compiles. Probably dumb question, but does that mean I was not using changepage?

It has been so long that I can't remember what I was trying to use changepage for.

5:32 PM

@JosephWright I'll wait on a little bit. If there are any more edits to the closed question, it would be an indication it should really be the open one.

6:00 PM

@JosephWright "stick to plain tex and latex 2.09" both are guaranteed to be stable

@DavidCarlisle First part of my answer, more or less

> If you want 'will never change again', then plain TeX is probably your best bet

@DavidCarlisle Or do you want to answer?

@JosephWright probably better if you do it really you are closer to the action to remember which bits are more or less done

@DavidCarlisle OK: was my guess

6:26 PM

@DavidCarlisle Care to check my answer?

6:52 PM

@JosephWright looks OK (I voted for it:-)

7:03 PM

@JosephWright Free rep. ;-)

Hi folks, what causes the 6 errors when invoking the following with pdflatex -shell-escape?

\documentclass{book}
\usepackage{filecontents}
\begin{filecontents*}{template.tex}
\documentclass[preview,border=0pt,graphics]{standalone}
\usepackage{graphicx}
%\makeatletter
%\define@key{Gin}{width}{}
%\define@key{Gin}{scale}{}
%\define@key{Gin}{height}{}
%\makeatother
\begin{document}
\includegraphics[\varone]{\vartwo}
\end{document}
\end{filecontents*}

\usepackage{graphicx}



\let\temp\includegraphics

\renewcommand\includegraphics[2][]{%
	\temp[#1]{#2}%
	%\immediate\write18{latex -jobname=#2 "\def\noexpand\varone{#1} \def\noexpand\vartwo{#2} \noexpand\input{template}" && dvips #2 && …

The objective of the above code is to create a PDF version for each imported EPS figure and save each with its own name separately.

@PauloCereda Want to see a photo of a duck cake?

@NicolaTalbot Yes please! :)

@NicolaTalbot Oh my! It's lovely!

7:18 PM

@PauloCereda It's great! I picked it up from the bakery today. The book launch is tomorrow after mass! :-)

@NicolaTalbot Yay! Take more photos of the book launch, please. :)

@PauloCereda Will do :-)

@PauloCereda Have you seen the world's cutest frog?

@NicolaTalbot LOL

@PauloCereda It's like a squeaky toy!

7:34 PM

@NicolaTalbot Indeed! :)

8:01 PM

@DavidCarlisle @NicolaTalbot The end of an era: Sachin Tendulkar.

@DavidCarlisle The 'stable' question reminds me (again) we need to sort \tl_to_lowercase:n

8:23 PM

@AlanMunn maybe @PauloCereda could do a blog article reprising hos career

@DavidCarlisle He could illustrate it with a duck holding a cricket bat ;-) (Not that Sachin Tendulkar got many of those!)

@NicolaTalbot Or holding a basketball.

@NicolaTalbot 14 apparently, in Test matches.

8:47 PM

@AlanMunn Not bad for 200 test matches!

@egreg 19 seconds, I suppose I should delete:(

@DavidCarlisle And with a moooore detailed answer. ;-)

@DavidCarlisle You also have an \expandafter too many. :P

@egreg well it's gone now:-)

How to invoke dvips and ps2pdf when latex call makes use of -out-directory as follows ?

latex -jobname=#2 -aux-directory=trash -out-directory=output \unexpanded{"\def\varone{#1} \def\vartwo{#2} \input{template}"} && dvips #2 && ps2pdf -dAutoRotatePages=/None #2.ps

I tried the following but it does not work.

latex -jobname=#2 -aux-directory=trash -out-directory=output \unexpanded{"\def\varone{#1} \def\vartwo{#2} \input{template}"} && dvips ./output/#2 && ps2pdf -dAutoRotatePages=/None ./output/#2.ps

@DonutE.Knot should work but an alternative would be to add cd output as a command step afer latex and before dvips. Or (simpler) not use -out-directory (in over 25 years of using tex Ive never felt the need to redirect the output in that way:-)

8:57 PM

@DavidCarlisle I added a third version, with \let\crefname\relax in the code for each cycle.

@DavidCarlisle Because I want to tidy up the file structures.

@DonutE.Knot tidy up afterwards:-)

@DonutE.Knot whenever people redirect the output they end up breaking stuff and asking on sites like this how to get latex or bibtex (or dvips or whatever) to find the file they just redirected, it's for at best a cosmetic improvement and it complicates all tex processing which makes so much use of communication via auxiliary files

@DavidCarlisle after adding cd output, everything just works fine. Congratulation. Thanks!

by the way -output-directory rather than -out-directory, the prev code has a typo.

@DonutE.Knot whatever, it's a bad idea whatever it's called:-)

@DavidCarlisle But it is strange, my trash (specified by -aux-directory) is always empty, the auxiliary files are moved to output instead.

9:07 PM

@DonutE.Knot is there an aux-diirectory flag? pdftex--help doesn't list it

@DavidCarlisle OK. I have to recheck it. I got it from latex-community.org/viewtopic.php?f=5&t=3596.

@DavidCarlisle I think there is for MiKTeX

@egreg I've used miktex as often as I have used --output-directory

@DavidCarlisle I too.

But I had a good usage for --output-directory connected with the gmp package; however, at the time the option didn't work with mpost.

I blame Taco, of course.

9:28 PM

@egreg It's always good to have someone to blame

@egreg :-)

@JosephWright I couldn't blame a bug in longtable or colortbl, unfortunately.

@egreg You could try ;-)

9:46 PM

I'm palindrome in Math.SE. :)

@egreg Cool

@egreg 1 ;-)

10:01 PM

@JosephWright No, a bit more. ;-)

But I'm very far from Legendary there.

A pity there's not a badge for being rep capped 500+ times.

@egreg Wouldn't be awarded a lot

@JosephWright Well, I'm at -28 answers for the tenth gold tag badge: tex-core

@egreg All right for some

@egreg No gold tag badges here

@JosephWright Too much time in the laboratory.

@egreg Probably

10:09 PM

@JosephWright Making things explode is funner, I guess.

@egreg When it's expected, yes

@egreg I blew up my fumehood as an undergrad

@JosephWright mathematics is safer

@JosephWright Making a mistake doing math is less threatening

@DavidCarlisle Physically, I guess so, but not so sure intellectually :-)

@egreg Depends: that business with the metric versus imperial units for the Mars lander didn't go so well ...

@JosephWright That's applied math.

10:12 PM

@JosephWright work in finite fields, units less important then

@DavidCarlisle I like units ;-)

@egreg "There's a much neater way:" but no tick:-)

@DavidCarlisle :( People often prefer doing things the wrong way.

@egreg Thanks for filling in the details about about \parshape on the linguex question.

@egreg I explained what was wrong with the code, you just said what he should have done instead:-)

10:29 PM

@AlanMunn Been there, done that. ;-)

11:14 PM

Back from the mass. What did I miss? :)

@PauloCereda Just that David got a tick for the wrong answer.

@egreg Oh my! :)

@PauloCereda But I posted an answer 19 seconds before David's and I got the tick.

A: When are you not on TeX.SX?

I think I'm not into TeX.sx when... well... I have no idea. :) After all, last time I wasn't here was April 23, 2011, according to my profile. :)

oopsie, into = on.

11:36 PM

@PauloCereda do you plan to post your beautiful gource video to youtube? :)

@cmhughes Hi Chris! :) I'm not sure, I'm doubt. :)

@PauloCereda ok :) it is beautiful :)

@PauloCereda ignore the sour grapes

@cmhughes :)

@DavidCarlisle LOL
