(Wanders back in for a bit.) Should have actually posted what I was coming here to ask when I popped my head in here last night and nobody was home; let me fix that now: how does one get leading indentation for paragraphs of text within a \parbox contained in a cell of a tabular environment? I tried using indentfirst, but it didn't work. Or would resolving this involve me posting my source in a new question outside of chat?

@RandomDSdevel I think if you ask a question it will certainly answered. They are all sleeping in Europe and America at this moment...

David Carlisle

06:55

@RandomDSdevel just set \parindent but why have you got a parbox in a tabular, rather more usual to have a p column (although they have 0 parindent by default as well)

Ulrike Fischer

@samcarter neat ;-) (and I won't suggest a lot of zeros and ones one the stripes ...)

Paulo Cereda

12:05

@egreg: should I add a background music?

egreg

@PauloCereda Lady Gaga?

Paulo Cereda

@egreg I was thinking more of a Venice song. :)

Paulo Cereda

@egreg LOL

CarLaTeX

@egreg I drank a (very good) spritz in Venice: only 3 euros (not in S. Marco)! In Milan impossible to find at that price.

Paulo Cereda

12:47

@samcarter: Can we have a Spanish Inquisition duck? So can I add in my slides and say that nobody expects it?

Ulrike Fischer

@PauloCereda Should it sit on a cushion or hold it? ;-)

Paulo Cereda

@UlrikeFischer ooh it's a good question. :)

samcarter

Oh lord...

Paulo Cereda

@samcarter ooooh

samcarter

13:01

@egreg I felt sorry for the poor data -- did nothing wrong a was but behind all these bars.

@UlrikeFischer You just gave me a great idea for our counter wizard! Thanks!

Ulrike Fischer

13:21

@samcarter We think it needs a goatee or a beard ...

Don't we have macros that can resize non gfx to a box of a given size but keeping the aspect ratio? Say I have something that needs to be scaled to fix a box of size 2x1, then I can use \resizebox{2cm}{!}{...} if it is something wide, but have to use \resizebox{!}{1cm}{...} if the contents is narrow but tall. What have I forgotten here?

Joseph Wright

@daleif Not sure what you mean: what's wrong with the \resizebox operations?

@DavidCarlisle Would appreciate any thoughts on the colour checkin I've just pushed

daleif

@JosephWright I need these two boxes to also have the same height (or the contents to fit inside that size)

\documentclass{memoir}
\usepackage{graphicx}
\begin{document}

\fbox{\resizebox{1cm}{!}{Test test test}}

\fbox{\resizebox{1cm}{!}{A}}

\fbox{\resizebox{!}{5mm}{Test test test}}

\fbox{\resizebox{!}{5mm}{A}}

\end{document}

Perhaps I should just use a double \resizebox

Joseph Wright

@daleif Yes, so resize them to the same height!

@daleif Ah, perhaps you mean 'resize only if larger than X'?

samcarter

@UlrikeFischer Totally true -- however I am not sure where to put it, the bill interferes with the location...

daleif

13:33

@JosephWright or resize if size larger than given X \times Y (like keepaspectratio in \includegraphics but in general)

Joseph Wright

@daleif Package adjustbox?

daleif

@JosephWright looking at it, it is just not clear about the aspect ratio

Seems to work. \maxboxsize*{1cm}{5mm}{...}

Joseph Wright

\documentclass{book}
\usepackage{expl3,xparse}
\ExplSyntaxOn
\NewDocumentCommand \resizecontent { m m +m }
  {
    \group_begin:
      \hbox_set:Nn \l_tmpa_box {#3}
      \box_autosize_to_wd_and_ht_plus_dp:Nnn \l_tmpa_box {#1} {#2}
      \box_use:N \l_tmpa_box
    \group_end:
  }
\ExplSyntaxOff
\begin{document}
\fbox{\resizecontent{1cm}{5mm}{Test test test}}

\fbox{\resizecontent{1cm}{5mm}{A}}

\end{document}

@daleif ^^^ perhaps?

daleif

No need, the manual says (on the name page): "If required the content is scaled down so that the width and height is equal or smaller than the given values,
but does not change the aspect ratio."

Joseph Wright

@daleif Ah, much the same thing

daleif

13:39

Now I just need to figure out how to typeset a russian char. (trying to recreate an x-word puzzle via tikz).

Done

David Carlisle

14:06

@JosephWright OK although might not be able to look until tomorrow

Joseph Wright

14:17

@DavidCarlisle No rush

David Carlisle

14:44

@egreg tex book lies again then? :-)

\ddanger If \TeX\ sees a character of category~10 (space), the action
depends on the current state. If \TeX\ is in state $N$ or $S$, the
character is simply passed by, and \TeX\ remains in the same state.
Otherwise \TeX\ is in state $M$; the character is converted to a token
of category~10 whose character code is~32, and \TeX\ enters state~$S$.
The character code in a space token is always~32.

egreg

@DavidCarlisle See the discussion on funny space tokens

David Carlisle

@egreg yes but that's uppercasing to change the character code your exanpl eis just using teh character scanner, oh isn't \if?!\message testing space and message?

egreg

15:29

@DavidCarlisle Yes. The right test should be

\catcode`?=10 \catcode`!=10
\def\qm{?} \def\em{!}

\let\$\empty

\if\$?\$!\message{equal}\else\message{not equal}\fi

\ifx\qm\em\message{equal}\else\message{not equal}\fi

\bye

@DavidCarlisle You can answer tex.stackexchange.com/questions/393359

David Carlisle

16:15

@egreg no time actually, tick is yours for the taking:-)

Joseph Wright

@DavidCarlisle, @egreg Spaces keeping us entertained :) (I think I've annoyed someone ...)

Paulo Cereda

@JosephWright ooh Frank

I like annoying Frank too

:D

Joseph Wright

@PauloCereda Possibly, but not the person I have in mind

@PauloCereda I'm tempted to star that ;)

Paulo Cereda

@JosephWright let's annoy him regardless. :D

@JosephWright I'd star it too. :)

David Carlisle

16:31

@JosephWright I blame git:-)

Joseph Wright

@DavidCarlisle :)

egreg

17:23

@DavidCarlisle Made CW

David Carlisle

@egreg thanks, back later this evening, will be offline for a bit. pineapple pizzas to be eaten

Joseph Wright

18:01

@DavidCarlisle Have fun

@DavidCarlisle, @egreg Please check my latest attempt to explain spaces :)

Paulo Cereda

18:15

@JosephWright: are we planning our annual meeting? :)

CarLaTeX

18:43

@PauloCereda Are you a fan of "Big Bang Theory", too?
https://tex.stackexchange.com/questions/393382/is-there-a-latex-implementation-of-bazins-punctuation-marks#comment977525_393382

Paulo Cereda

@CarLaTeX Actually, no. :) I don't like the show. :)

CarLaTeX

@PauloCereda Why do you know bazinga, then?

Paulo Cereda

@CarLaTeX I know a lot of things. :)

CarLaTeX

@PauloCereda Duck are clever! :):):)

Paulo Cereda

@CarLaTeX We are. :D

Joseph Wright

19:02

@PauloCereda Er, yes: I need to book it

Paulo Cereda

@JosephWright uh-oh. :)

RandomDSdevel

20:29

@DavidCarlisle How'd I manage to forget about p column specifications?! Now the solution seems obvious. Thanks!

David Carlisle

@PauloCereda just got back, it wasn't me that had duck:-)

RandomDSdevel

@DavidCarlisle: Hmm, the obvious fix doesn't seem to be working; maybe the \flushleft environments I'm using within the table cells are messing things up somehow, but I'm not sure I can see how that would be the case… (Scratches head.)

David Carlisle

@RandomDSdevel flushleft adds vertical space, you probably want \raqggedright\arraybackslsh but hard to tell, you would be better asking a question on site really.

RandomDSdevel

20:45

Yeah, I figured I was testing my luck trying to work through anything more complicated than something just a line or two long here in chat.

@DavidCarlisle: I thought I'd try \raggedright\arraybackslsh before heading over to the main site, but I get an 'Undefined control sequence' error for the second of those two LaTeX commands; is it in a package I haven't included?

David Carlisle

@RandomDSdevel oh \usepackage{array} you pretty much need that for any non trivial tabular environment

RandomDSdevel

Ah, makes sense.

@DavidCarlisle: That did the trick! Looking at the documentation of package array, though, I'm not sure I need the functionality of \arraybackslash, at least not for my use case. Let's see if removing it changes anything…

(I'm only putting one paragraph of text in each column.)

David Carlisle

@RandomDSdevel if you use \raggedright in the last column you will find out why we introduced it...

RandomDSdevel

Yep, I don't see any difference.

(perhaps I'm missing some context here, though…?)

David Carlisle

@RandomDSdevel how are you ending your table rows, with \\ ?

RandomDSdevel

21:00

I've only got one row.

David Carlisle

@RandomDSdevel or rather you have the context but everyone else is missing it as you didn't ask as a question on site with a proper example:-)

@RandomDSdevel there is absolutely no point in a one row table the whole point of a table is to align things in columns.

RandomDSdevel

(Laughs.) I knew it was around here somewhere… It just goes to show how often I misplace things.

@DavidCarlisle: And, yes, just using something that made text columns would probably be a better idea, but I'm still in that same tutorial I was in the other day, and it hasn't introduced anything of the sort just yet — plus, this part of it's on tables, so I was using tabular environments. The next few exercises are less silly, I think…

David Carlisle

@RandomDSdevel \parbox{3cm}{a b c}\parbox{3cm}{a b c} would make two side by side paragraphs each 3cm wide, no table is needed

RandomDSdevel

@DavidCarlisle Of course. I'll keep that in mind for future reference.

(Though that makes me wonder what one would do to just type out a bunch of text without having to manually reflow all text in those columns while editing…; ah, that's rather irrelevant to what I've been doing, so I'll just research that later when I need it.)

David Carlisle

@RandomDSdevel manually reflow?

RandomDSdevel

21:16

@DavidCarlisle: If you end up making one of the columns so long that its text goes off the page.

I'm guessing there's an environment for automatic wrapping of text between columns or something, maybe in a package somewhere, but, again, I don't need to look for it just yet.

David Carlisle

@RandomDSdevel if you want text to flow from one column to another they are not separate paragraphs so parbox (or tabular) are the wrong thing use multicol package and just have a single text flow in multiple columns

RandomDSdevel

…and there's the package! I should try and remember that it exists for when I need it.

(None of my columns need wrapping right now, of course, so I think I'm done here.)

Thanks again, @DavidCarlisle.

(Wanders off.)
