There's probably a direct way to change the size of script math \sf@size , but how? I'm using \textsubscript or -super-, but it's just a bit too big.

Perhaps doubling would also work.

Yeah, actually even better, since a super- and subscript, or vice versa, don't extend above or below a bracket, requiring more depth or height

A high-severity bug impacting two popular command-line text editing applications, Vim and Neovim, allow remote attackers to execute arbitrary OS commands. Security researcher Armin Razmjou warned that exploiting the bug is as easy as tricking a target into clicking on a specially crafted text file in either editor. Razmjou outlined his research and created a proof-of-concept (PoC) attack demonstrating how an adversary can compromise a Linux system via Vim or Neowim. He said Vim versions before 8.1.1365 and Neovim before 0.3.6 are vulnerable to arbitrary code execution... Vim and Neovim have…

@DavidCarlisle ooh :)

@DavidCarlisle have you heard of spacemacs?

David Carlisle

@PauloCereda ah hide emacs so vim users use it, sounds like a plan...

@DavidCarlisle that's the idea, actually. :) I have it on one of my laptops and it can disguise quite well. :)

Hi

Sometimes, you have to write a document with a limited amount of words

Microsoft Word by default provides a word counter (if I recall correctly)

I've seen this question tex.stackexchange.com/q/534/63097, but I am definitely not satisfied

I was hoping that TexMaker had some intergrated functionality (without having to click on the pdf)

Furthermore, the existing functionality seems to count the words also in the title. Maybe these shouldn't be counted?

This seems to be a very big limitation of these editors

Paulo Cereda

2:37 PM

@yo' oh :)

yo'

@nbro the thing you ask for is quite tough to do. It would be doable with some hacks, and it won't be reliable. It could go wrong e.g. with accented letters, hyphenation can influence the count. Etc.

David Carlisle

@nbro that question comes up every week or so, my preferred answer is to tell people to tell whoever is asking for that number not to be silly, but that answer isn't always popular. A long long while ago, in a word counting thread on comp.text.tex I posted this example, it's not really reasonable to expect an editor to count words here, I think.

2:53 PM

@yo' Couldn't the LaTex compiler provide such functionality?

marmot

@PauloCereda As opposed to full ridge?

Paulo Cereda

@marmot ooh a pun

nbro

@DavidCarlisle Well, as I asked above, couldn't the compiler do this job? The compiler knows what is going to be rendered at the end. The compiler could provide this information to the editor

yo'

@nbro easier said than done really. The most reliable way currently really is pdftotext myfile.pdf | wc -w

David Carlisle

@nbro not really, it has no idea what is a word. Wth luatex you could probably make something plausible but since the number is arbitrary anyway I don't think many people are very inspired to make it robust.

@nbro how many words are in foo-bar $\mathrm{foo}-\mathrm{bar}$ ?

Ulrike Fischer

3:01 PM

@marmot have you time for a forest question?

David Carlisle

@marmot don't be lured into the forest, there be eagles there.

nbro

I don't know. But there could be a sophisticated software that allows the user to choose specific ambigouos cases, where text can be split differently and so the number of words can be different depending on the choice of the split

I guess this could be done, no?

David Carlisle

@nbro sure but that doesn't really fit in a tex typesetting engine, better to do that kind of thing in the generated pdf.

@nbro the source code of tex was more or less frozen in 1989 so basically no it can't feasibly be done in tex, as I say you could probably do something in Lua in luatex (I would expect someone has done something already) but using a generic pdf word counter is likely to be just as good or better, why does it have to be tex-specific?

marmot

@UlrikeFischer In a bit more that two hours, am about to go cycling. ;-)

@DavidCarlisle Only slow marmots get caught by eagles.

Ulrike Fischer

@marmot there is no hurry, I only want to know how to let the A, B, C here grow down: (I will be away in the evening)

\documentclass{article}
\usepackage[edges]{forest}
\forestset{%
mytree/.style={%
for tree={%
folder,

where level={0}{font=\large}{},
where level={2}{font=\bfseries}{},

@DavidCarlisle this marmot looks sweet on a bicycle built for one. :)

marmot

@UlrikeFischer If you remove `for tree={%
folder,

Ulrike Fischer

@marmot yes, but then the subtitles grow down too. I want horizontal subtitles and from there on downwards. I tried various places to change the directions and had already very interesting layouts ;-(

@marmot as a fall back I will make three trees, and the lines from the title manually ...

marmot

3:18 PM

@UlrikeFischer

i.e. do not add `folder` to `for tree` but just to forest. (Really need to go now.)

Moytaba

4:09 PM

Hi

David Carlisle

@Moytaba hello

Moytaba

I don't know Tex, but I'm curious whether I can solve a problem of mine with it? I have many screen shots of different sizes on a subject, and I want to print them, but when I import them in MS-Word, there's no separator line between them, strangely, I couldn't find a way for adding the line between them either(unless I want to do all of that manually!). I didn't know about the power of Tex until recently, but I encountered this problem and I searched for solutions so I got familiar with Tex.

I know Tex is much more powerful than that, but I just want to make sure if I learn it, I can solve my problem too. (Indeed I'm interested in Tex besides my problem too ;) )

Alan Munn

@Moytaba Sounds like a pretty easy thing to do with LaTeX, especially if the screenshots have sensible names.

Moytaba

@AlanMunn Great!

Sorry for dummy questions, but are all textbooks written with Tex programming?!

David Carlisle

@Moytaba er well you could do it in tex but really you are not using tex at all for that (ie no text typesetting) you may be better with something designed for graphical layout.

@Moytaba I do not understand the question, most textbooks are not typeset with tex at all, some are, it all depends on the author and publisher requirements.

Moytaba

4:14 PM

@DavidCarlisle Thanks but do you know of a special tool that can do that for me? Really I don't need it to be beautiful, I just need them to be printed and be neatly separated.

Alan Munn

@Moytaba I agree with @DavidCarlisle although it depends on how much the automation is more important than the layout.

Moytaba

I used ImageMagick (Linux terminal utility) to convert all of them to a pdf, but still they are on separate pages in the generated PDF.

Alan Munn

@Moytaba For example:

\documentclass{article}

\usepackage{graphicx}
\usepackage[margin=1in]{geometry}
\usepackage{pgffor}
%%%%%%%%%%%%%%%%%%%%%% Enter information below %%%%%%%%%%%%%%%%%%
\graphicspath{{}} % image directory
\newcommand*\ImagePrefix{} % prefix for image files
\newcommand*\numimages{} % number of images
%%%%%%%%%%%%%%%%%%%%% Enter above information %%%%%%%%%%%%%%%%%%

\parindent=0pt

\begin{document}
\foreach \x in {1,...,\numimages}{
\includegraphics[width=\linewidth]{\ImagePrefix\x}
}
\end{document}

David Carlisle

@Moytaba but there are thousands of applications designed to print photo albums in assorted layouts, essentially that is what you are describing, I think?

Moytaba

@DavidCarlisle like what? you mean things like collage?! in my case screen shots are mostly of text. not pictures.

Alan Munn

4:18 PM

@Moytaba I use the code above to make handouts from articles when I teach.

David Carlisle

@Moytaba no idea what people use (I'd probably use tex but I've been using that for 30 years) I just know that all kinds of apps get installed with cameras etc

Moytaba

@AlanMunn That's great! At first there's a YouTube playlist I've found, I'll watch the videos of it and then I'll check this. Thanks a lot.

David Carlisle

@Moytaba if they are screenshots they are presumably bitmaps so essentially pictures not text as far as the software is concerned

Alan Munn

@Moytaba Just remember, though that TeX has a moderately steep learning curve. So if this is a one time thing, it may not be worth it.

Moytaba

@DavidCarlisle yeah yeah by saying that I mean... you know collages are not very careful about keeping the whole images in the borders... I hope I'm getting my point across.

@AlanMunn Wow :))

The blame is on MS-Word and the world of software :P Or on me for not being able to find the right tool (yet)

Thanks guys for all the tips.

Alan Munn

4:22 PM

@Moytaba Well there's an obvious trade-off between a broad user base and automation possibilities.

Moytaba

@AlanMunn yes that's right

Sometimes I feel I'm an automation junkie (another word for lazy) :)

Alan Munn

'Automating' comes from the roots 'auto-' meaning 'self-', and 'mating', meaning 'screwing'.

David Carlisle

@AlanMunn hope no one sees the typical tex document I posted in a comment above:-)

@DavidCarlisle So you use the pen name Eunice Burr Couch I see.

@AlanMunn she didn't use an authentic 1st century catcode regime, so I had to transcribe it as above.

5:15 PM

Hello, everyone.

Do we have an equivalent to "else if" in plain TeX, or separate \if control sequences (each followed by \fi) have to be specified for similar effect?

* I stand corrected: not "each followed" but "each terminated".

marmot

@bp2017 \ifnum\X=2\relax \typeout{x=2}\else\typeout{x!=2}\fi

David Carlisle

@bp2017 no. just \else\if (but there is \cases for numeric tests =0,1,2,3...

bp2017

I did

ifdim#1=5pt
it's five: #1
\else\ifdim#1=4pt
it's four: #1
\fi

but it didn't work. I guess \ifdim behaves differently from \if then?

David Carlisle

@bp2017 you are missing a \fi at the end

bp2017

@marmot, @DavidCarlisle, thank you. (Also forgot to copy here the starting backslash.)

barbara beeton

5:54 PM

@AlanMunn -- Hmmmmph. This person provided the full source text, and proofread the output to make sure it matched correctly. (But she did voluntarily ask David whether he would consider coding it.)

Alan Munn

@barbarabeeton Yes, @DavidCarlisle seemed to be overselling his contribution. :)

barbara beeton

@AlanMunn -- To be fair, he did format it in such a way that it's nicely rectangular.

Alan Munn

@barbarabeeton It also suits the original xii.tex name a lot better.

barbara beeton

@AlanMunn -- You really should hear it sung, in person. But for that, you'd have to be in Providence on the second Monday after Thanksgiving. (Lots more sung in Latin on the same evening, mostly by the audience, and with seasonal readings in Latin, Greek and Sanskrit mostly by people who understand what they're reading.)

Alan Munn

@barbarabeeton Don't forget my thesis. youtube.com/watch?v=x8qB-PUw2AQ

barbara beeton

6:10 PM

@AlanMunn -- Yup. That's them. (But better in person, and it's a little different every year.)

bp2017

I expected "capacity exceeded" error (since infinite expansion) but "undefined control sequence" error was generated instead. I wonder why.

\def\z#1%
{ \edef\zz
{ %\z{4pt} % ERROR: UNDEFINED CONTROL SEQUENCE (SAME AS LINE BELOW)
\edef\zz{} % I ASSUME \z WOULD EXPAND INSIDE \edef TO \edef\zz{}\zz#1 (THIS LINE IMITATES THIS EXPANSION)
}
\zz
#1
}
\z{5pt}

Alan Munn

@bp2017 \edef expands its argument, so \z is not defined at that time.

bp2017

@AlanMunn, but \z is commented in my example and is not "given order/command" to expand, \edef\zz{} doesn't contain \z.

Alan Munn

@bp2017 Sorry I meant to type \zz. The inner \zz isn't defined when you do the \edef.

@bp2017 Or maybe I'm misunderstanding the actual code you're running.

Joseph Wright

6:39 PM

@bp2017 You need a 'holder' \zz definition

@DavidCarlisle, @egreg, @UlrikeFischer I'm thinking of moving all the expl3 options to l3sys, as they are 'runtime dependent': make sense?

bp2017

@AlanMunn, I think \zz of \edef\zz inside another \edef\zz is treated like an expansion of \zz (not definition), and (as you said) \edef\zz has to complete before \zz is available for expansion. I figured this would be a simpler example:

\edef\zz
{ \edef\zz{}
}
\zz

resulsts in same error

Joseph Wright

7:03 PM

@bp2017 Yup: you have not defined \zz at the point you try to expand it

Paulo Cereda

@DavidCarlisle ooh

Alan Munn

@PauloCereda Hey, belated Happy Birthday! I assume you are too far north to have lost power?

Paulo Cereda

@AlanMunn thank you! No worry, it's still in the range. :)

Alan Munn

@PauloCereda Where C is in Buenos Aires has lots of hospitals, so power came back first there. :)

Paulo Cereda

Alan Munn

@PauloCereda Yes, it was back on by around 1:30 local time.

Paulo Cereda

7:24 PM

@AlanMunn interesting

Alan Munn

@PauloCereda Do you know how far it reached into RS? Was PoA affected?

Paulo Cereda

@AlanMunn let me check, hold on. :)

@AlanMunn Brazil wasn't affected, the report says.

Only Argentina and Uruguay.

Alan Munn

@PauloCereda I see. The reports I read said that social media (world's most reliable source) said the south of Brazil was also affected.

Paulo Cereda

@AlanMunn I will check further.

Alan Munn

@PauloCereda I suspect that those reports were incorrect. Maybe some places very close to the border got affected.

Paulo Cereda

7:28 PM

@AlanMunn Ah:

> O jornal argentino Clarín afirmou que o corte de energia também afetou pontos do sul do Brasil e do Chile. A Companhia Estadual de Energia Elétrica (CEEE) e a RGE, porém, afirmaram que o apagão não teve reflexo no Rio Grande do Sul.

Then I read about a blackout in Porto Alegre, but it had a different cause.

bp2017

@JosephWright, I'm trying to understand how nested \edef works as iteration (in one of the answers that were provided to me), so I am trying to simplify and build on that simplification the original "loop".

Do we have logical operators in plain TeX that can be used with \if-series of commands, like \ifnum#1<5 AND #1>0?

Alan Munn

@PauloCereda ok

Paulo Cereda

@AlanMunn I will keep looking. :)

Alan Munn

@PauloCereda Don't worry, that sounds definitive.

David Carlisle

8:01 PM

@JosephWright seems OK to me

@bp2017 I have an answer on nested edef somewhere I'll see if I can find it, there is no primitive and or or but of course you can define macros for them

bp2017

@DavidCarlisle, I eventually came up with this sample, but I need to understand it better

\def\z#1%
{%
\ifnum#1<6
\edef\zz
{%
\noexpand\z{\the\numexpr#1+1}
}
\zz
#1 % value of #1 insize respective \z
\else
#1 % 6
\fi
}
\z{3}

David Carlisle

@bp2017 this was the answer I had in mind

57

A: Advantages and disadvantages of fully expandable macros

I think it is best not to compare the expandable/not expandable distinction to concepts from other languages. The main issues relating to expansion are really particular (some would say peculiar) to the execution model of TeX. TeX has two main modes of operation.All assignments and boxing operat...

@bp2017 6 5 4 3 (where did that code come from?, the zz gives some clues...)

@bp2017 simpler to write it without the \edef:

\def\z#1%
{%
\ifnum#1<6
\expandafter\z\expandafter{\the\numexpr#1+1}
#1 % value of #1 insize respective \z
\else
#1 % 6
\fi
}
\z{3}

@AlanMunn isn't São Paulo in Argentina? :-)

Skillmon

@DavidCarlisle not a good loop. Less than 5000 recursions make it break already.

Ulrike Fischer

8:21 PM

@JosephWright looks ok..

David Carlisle

@Skillmon would serve you right.

bp2017

8:37 PM

@DavidCarlisle, thank you. It'll take me some time to read and comprehend the answer you linked to. At this time \noexpand inside \edef which expands (and yet doesn't expand?) to outer \def (containing that \edef) reminds me very much of the \show command (and if \noexpand is removed, reminds me of the \showthe command).

David Carlisle

@bp2017 not really related to \show. \noexpand\foo just expands to \foo (but the expansion of \foo is suppressed )

AlexG

@DavidCarlisle Yes, it is. Ok, the official spelling is different: goo.gl/maps/vohAf6GZmVDJ1LMh9

bp2017

@DavidCarlisle, and yet "operations" inside \foo are "executed" inside \foo with \noexpand. Otherwise it's hard to explain how the loop in example above is being able to iterate. But I haven't read the answer (which was linked) yet (I'll have time to study it in an hour or so).

David Carlisle

@bp2017 no, the code gets run after the edef, that's the whole point (although as I say the edef isn't needed there)

@AlexG That explains why @PauloCereda speaks Spanish so well.

@bp2017 given \z{4} the edef defines \zz to be \z{5}space so the immediately following call to \zz effects the recursion.

bp2017

9:15 PM

What's confusing is difference between

\edef\zz
{%
\noexpand\z{\the\numexpr#1+1}
}

and

\def\zz
{%
\z{\the\numexpr#1+1}
}

David Carlisle

@bp2017 add \show\zz after the definition, the difference should be obvious then

bp2017

It's confusing because \noexpand, by its name/meaning, assumes no expansion of \z inside \edef which expands everything), which is same if \z were present inside \def. But then it behaves differently.

David Carlisle

@bp2017 as I said, if #1 is 4 then the first is the same as \def\zz{\z{5}} the second is the same as \def\zz{\z{\the\numexpr4+1}} which are not the same at all

@bp2017 no, as I say \noexpand\z just expands to \z but then the expansion of \z within the edef is suppressed, after the definition is completed that is just the normal token \z though, and no record of \noexpand is in the definition.

bp2017

So why do we need \edef for this particular case then, if \edef doesn't expand \z with \noexpand? (I guess I need to re-read everything and try to make sense of it).

David Carlisle

@bp2017 it expands the \the

bp2017

9:22 PM

@DavidCarlisle, oh, so that's what the matter is.

Now it's starting to make sense to me.

David Carlisle

@bp2017 as I said above in one case you get \z{5} (as \the was expanded) and inthe other you get \z{\the\numexpr4+1} (because it isn't expanded)

marmot

@DavidCarlisle Shouldn't it be \teh? ;-)

@marmot It's not far from where I grew up. I suspect that they are squirrels not true marmots.

marmot

@DavidCarlisle I was hoping they will make it to the LaTeX level, and not get stuck at the Word level.

David Carlisle

@marmot they are just being modest: they only mention Word in the title but the internal document properties reveal a tex ancestory

David Carlisle

@PhelypeOleinik given that they messed up tens of thousands of \\ in previous times, that is not impossible....

@DavidCarlisle I wasn't around when that happened, but I've seen some discussions about it.

David Carlisle

9:59 PM

@PhelypeOleinik they knew how it happened and they had corrupted the back end store but rather than fix it with a global edit they made us fix it through the web interface which throttles access to 5 seconds per edit which mean it took days rather than seconds (and only then after @ShreevatsaR had tuned a javascript access so we could do edits at that rate)

Ulrike Fischer

@marmot partly. I decided to "outsource" the title and to use two parallel forest trees:

@UlrikeFischer would have been simpler in picture mode

@DavidCarlisle Ouch. I thought it was one or another post which was messed up. So it was sort of on purpose on their end?

Ulrike Fischer

@DavidCarlisle the task was "not lots of draw instructions" (and the tree can grow ...)

David Carlisle

@PhelypeOleinik no it was literally tens of thousand of posts.

@PhelypeOleinik it was a messed up regex normalization which changed every \\ to \ in the whole site. But the trick was it messed up the back end stored markdown but not the cached html that is normally displayed, so it only came to light months later as people edited it, then they did a global change changing http to https for images and that made them regenerate every page with an image then all the broken \\ showed but that was a year after the initial error

@DavidCarlisle I think I can see some outliers in that graph...

@DavidCarlisle Seems pretty stupid to do that kind of substitution for no good reason...

David Carlisle

@PhelypeOleinik probably random data input error: clean the data and redraw a cleaner curve:-)

Going to eat dinner now (no duck :-)

@PhelypeOleinik maybe you will get some another day:-)

@marmot that makes a star layout from the title to the subtitles. I'm looking for an horizontal folder layout, a bit like this (but the title should be more above the line:

@marmot I think I'm not expressing myself very well ;-). Now the title and the subtitles are perfect, but the abc are not vertical. ;-) I need the top of the second and the bottom of your first solution. Somehow the tree should grow on the first level to the right and then down.
