@DavidCarlisle hey david, you around?

got a question about the answer you gave me for this question: tex.stackexchange.com/questions/391885/…

it works great, but i am wondering if i am asking for too much if i'd like to be able to write an operator (say for the sake of example, @), simply using the the character for the operator itself in math mode (e.g. write 2 @ 1, instead of writing 2 \myat 1), but still have it behave like \myat, and not the usual @

would that even be possible?

i was searching around for ways to make it happen, and my best guess is that i use some sort of "find and replace" macro to automatically expand every appearance of a particular character, but then i have to make sure that non-math-mode appearances of the character are not affected

hmm, maybe this answer would be useful: tex.stackexchange.com/questions/127464/…

what is the purpose of @ in latex macros?

cfr

@barbarabeeton Could you explain why the example on page 5 of the amsthm documentation starts with \begin{thm} but ends with \end{theorem}? Is this intended? It just seems very unusual.

@user89 It marks them as internal. Generally, such macros are expected in class and package code, but not in the body of documents. David is saner than me and probably asleep.

user89

@cfr right you are, i got a pretty good answer by looking up the purpose of \makeatletter

@cfr -- thanks for asking. it is definitely a bug that needs to be corrected! i'll make a note and look at it again tomorrow, when i can actually do something about it.

Hey all, I'm looking for some quick help imitating a certain configuration in one of my textbooks. Would it be appropriate to post a picture here in chat and ask for some advice?

I've tried searching for it already, but I don't think I know the proper wording to get good results. (I'm fairly new to LaTeX)

@ryan I think it's better to build an MWE and ask on the main site. This is not the correct place for an elaborate question... :)

ryan

@CarLaTeX, will do, thanks!

CarLaTeX

@ryan You're welcome, this way it could be useful also to other people in the future :)

Q: \makeatletter explained

I am using the following code in my beamer document to make the frame title's appear in the table of contents: \documentclass{beamer} \usetheme{default} \usepackage{bookmark} \usepackage{etoolbox} \usepackage{graphicx} \makeatletter \apptocmd{\beamer@@frametitle}{ \addtocontents{toc} {\protec...

@user89 you don't need to do that

@JosephWright is it? I'd seen discussion about a new bar on meta but this one looks same to me:-) (oh are you seeing the mod preview of it)

Still trying to make this code (tex.stackexchange.com/a/391948/67761) compatible with Alan Munn's elegant code (tex.stackexchange.com/a/392086/67761)

David Carlisle

@VincentVerheyen alan (and I) assumed you wanted \tooltip{a}\includegraphics{..} but the tooltip definition you have has two arguments so the syntax is \tooltip{a}{\includegraphics{a}} with an extra set of {} around the include

wow

you figured that out quickly :)

when I add the extra brackets,

your code still compiiles

but it doesn't give the desired position on the page such as tex.stackexchange.com/a/391948/67761 does

David Carlisle

@VincentVerheyen have you defined tooltip?, I just put in a stub definition (as did Alan)

Anonymous

@DavidCarlisle If you mean: are the images outputted? Yes, they are, so in that way I have re-defined tooltip.

Anonymous

Your code on itself compiles greatly.

David Carlisle

@VincentVerheyen I just defined \tooltiop{a} to print [ttip-a] at that point,

But how could I use the code between the first instance of

and the last instance of

David Carlisle

@VincentVerheyen no I mean we just answered the question you asked how to take abc and loop applying a then b then c to some code, the actual code you use inside the loop is up to you.

@DavidCarlisle I understand that the question has been answered perfectly by both of you

David Carlisle

@VincentVerheyen that code just defines \tooltip as a command with two arguments, so use that and then use that two argument \tooltip inside the loop

Anonymous

I wish I did, but I can't follow.

I have now put your code

@DavidCarlisle somehow this doesn't make the tooltip interactive

@CarLaTeX Good morning. here it is hot - Come here that in Milan it is almost always raining in autumn and winter. :-)

David Carlisle

7:46 AM

@VincentVerheyen of course not you have defined \tooltip to do nothing: \def\tooltip#1{#1}

@JosephWright you are the in privileged few:-) ^^^

Joseph Wright

@DavidCarlisle :)

David Carlisle

@VincentVerheyen you need the definition of the toolip from the first question and use with two arguments so \tooltip{tooltip \tmp}{\includegraphics{file-\tmp} or whatever you need.

Joseph Wright

And I can't believe some places still use fax machines. The electrical signals waste so much time going AROUND the Earth when neutrino beams can go straight through!

@Sebastiano Unfortunately my job is in Milan :)

@JosephWright Just saw: miktex is on github: github.com/MiKTeX

yo'

@egreg only for mods I think

egreg

11:27 AM

@yo' I see. The transition is taking very long, it seems.

yo'

@egreg yeah

Skillmon

11:44 AM

I just found that using \NewDocumentCommand{\myverb}{ v }{ #1 } and then \myverb{a : a} produces two whitespaces after the colon.

yo'

@Skillmon Try \NewDocumentCommand{\myverb}{ v }{#1}

ah sorry, that's a nonsense (well, maybe it's not)

Skillmon

@yo' it is, why should those whitespaces (which should be ignored in xparse) insert a space in the middle of #1?

The output then is a : a

yo'

@Skillmon it's not two spaces. It's \nonfrenchspacing taking action

\documentclass{article}

\usepackage{xparse}

\NewDocumentCommand{\myverb}{ v }{#1}

\begin{document}

\centering\tt

\nonfrenchspacing

X\myverb{a : a}X

X12345X

\frenchspacing

X\myverb{a : a}X

\end{document}

@Skillmon And xparse does not trim spaces, it's \ExplSyntaxOn that makes them ignored

Skillmon

@yo' you're right, sorry. And yes, it's the \nonfrenchspacing. Wonder why this is the default.

yo'

@Skillmon It's language specific. I for instance pretty much prefer nonfrenchspacing documents

Skillmon

11:54 AM

@yo' but it's disturbing/irritating to use on verbatim input by default.

Joseph Wright

@UlrikeFischer Yes: I'm not sure which 'bits' of MiKTeX this is!

yo'

@Skillmon no. It would be irritating if xparse tried to solve it the issue itself.

Skillmon

@yo' if you say so :)

yo'

@Skillmon LaTeX is good because you know what it does.

LaTeX is good, because who know what it does?

Ulrike Fischer

@JosephWright As far as I can see, everything. And Christian just made a commit about my last bug report ;-) github.com/MiKTeX/miktex-packaging/commit/…

Skillmon

12:31 PM

@yo' and obviously I didn't, so it was bad

Torbjørn T.

@egreg Well, they did mention "weeks" as a timeframe, didn't they? I see in meta.stackexchange.com/questions/300829 that it now says "Assuming no significant issues are discovered we will roll out to all sites within the next couple weeks"

yo'

1:48 PM

@Skillmon well, if you asked on the site with a proper MWE, I would have upvoted the question and @egreg would probably provide a 5-page answer on the issue :D

Skillmon

@yo' most likely :)

@UlrikeFischer I meant that it's not like the TeX Live SVN: no (almost) daily checkins of TeX packages
