Back from the waterfalls, water dam and stuff. However, the best was the buddhist temple, and a small zoo --- I saw.araras for the first time IRL! @PauloCereda

^^ this quite sums up my experience with arara

@JosephWright I see what you mean about "explosion". Let's give it some time and thought, I have to first see what I gotta do with all of it.

@JosephWright btw, I just realized I also use cd "./subfolder" && pdflatex "./file-in-subfolder", which is significantly different from pdflatex --output-directory "./subfolder" "./subfolder/file-in-subfolder". Not sure how to deal with this sort of stuff (like running two commands in a single \ShellEscape call...

Hi folks. I want to make the following a no-op.

\node [font=\bfseries, align=center] at (14,-3){\includegraphics[width=.25\textwidth]{\Sigfile}};

TeXnician

@Skillmon Personally I would not use a dedicated package, but probably, because I would use tcolorbox in reality. I don't know if I would mind the "weight" of the package. But maybe a non-TikZ-user would be a better indicator whether it would be useful.

Faheem Mitha

Currently I'm just commenting this out, but I was wondering if making \Sigfile empty would achieve the same effect.

I guess I could try it.

TeXnician

@Skillmon Thanks for the reminder, I thought it was there but haven't found it in the documentation that fast.

Faheem Mitha

No, it seems \includegraphics is not ok with an blank space. Unsurprisingly.

manooooh

@PauloCereda LOOK
^^^^ !! My sister came from Morro de San Pablo, Brazil and gave me this beautiful key ring. Do not you think it's beautiful? `:)))))`.

Do you know that place? She returned to Argentina today after being five days, says she liked it a lot because in one of the islands where the streets were not asphalted, but covered something like wooden planks. She also told us something that caused us a lot of grace: there are no taxis as you usually know them, but they are like a kind of... taxi wheelbarrow? where they carry merchandise, objects, and even a woman!! Hahaha. Have you see…

Could someone please send me the screenshot of the now-deleted answer, here: tex.stackexchange.com/questions/442744/…? Thanks.

@Blue Better ask @samcarter why she deleted it. She is a regular on the chat; expect an answer when she's back.

@Blue Hi! I deleted the answer because it really was a dirty hack and I later noticed that it causes a couple of problems. If you want to see the code, I paste it here:

\documentclass[aps,twocolumn,groupeaddress,showkeys]{revtex4-1}
\usepackage[utf8]{inputenc}
\usepackage{pgfplots}
\usepackage{tabularx}
\usepackage[colorlinks=true,linkcolor=blue,citecolor=blue,urlcolor=blue]{hyperref}

Can someone give me a pointer on doing something as follows? I know I've done such things before, but I can't find the code.

If something is defined (could be a macro, could be something else), then a macro does one thing, if not, does another thing.

In my case, I want one of those cases to be a no-op.

samcarter

@Blue The problem with my \hfill approach is that the ; is pushed to the very end of the line (btw why are you concluding your thank you notice with a full stop if your class automatically inserts a , afterwards? Without the . it would fit in a line and the problems would not exist in the first place )

Faheem Mitha

If I have something very similar on hand, I can usually easily adapt it. But TeX is very thorny for non-experts, even to write something as simple as this.

samcarter

@Blue And the problem with your '\linebreak workaround is that the ; is pushed to the next line which does not look good either.

@Blue It would also be helpful if you could answer the question by @cfr tex.stackexchange.com/questions/442744/… about the numbers before the names.

@FaheemMitha Have a look at the etoolbox package. It provides several commands to deal with cases like this.

Faheem Mitha

@TeXnician Yes, I'm looking at it. Specifically the boolean commands.

TeXnician

@FaheemMitha There are also commands for dealing with commands and existence checks…

Faheem Mitha

@TeXnician I was trying \ifbool. Did you have something else in mind?

TeXnician

@FaheemMitha Yes. I thought you wanted \ifdef, but as I don't know your use case I think you should read the documentation.

Faheem Mitha

12:27 PM

@TeXnician I thought I could use a boolean instead. In this case it seemed a natural thing to do.

I just happened upon

TeXnician

@FaheemMitha That's fully up to you and I was just giving my interpretation of your question here. If you want a detailed answer which may relate to a given MWE it is better to ask the question on the main site, but otherwise it's your decision what to choose and which advise to follow.

Q: TeX questions on StackOverflow

Before you close this question as a duplicate: I know that the common sense in the meta answers is "TeX questions on Stackoverflow are on-topic there and we separately answer questions, even if they are duplicates on SO". The motivation for this post is the following: Lately there have been some...

So, how are TeX questions on SO handled now? Is there some protocol for getting them moved?

@TeXnician Yes, I understand.

TeXnician

@FaheemMitha Yes, if they are fresh enough mark them for migration. Otherwise it's hard…

Faheem Mitha

@TeXnician But presumably someone needs to do that.

Joseph Wright

@DavidCarlisle, @UlrikeFischer I've nearly sorted PDF-based testing in a more fluid way than at present. I plan to do some more cleanup (e.g. making the list of tests themselves flexible), then update l3build.

Faheem Mitha

So, are the functions in etoolbox considered a "modern" way of doing things? Or just LaTeX per usual?

Ulrike Fischer

@JosephWright ah good. What is tested/compared?

Stefan Kottwitz

3:43 PM

@FaheemMitha The etoolbox functions are tools for LaTeX and eTeX at that time (2007--2011). Since then, there were a few fixes or small additions. Joseph took over maintenance since it was abandoned. But of cause he is focused on LaTeX3, that should be considered as modern.

Joseph Wright

@UlrikeFischer Binary comparison: generated PDF versus reference PDF

Faheem Mitha

@StefanKottwitz Hmm. So what would be the LaTeX 3 way of handling what I described above? Or should I ask a question?

Joseph Wright

@UlrikeFischer We've looked at 'extracting' bits of the PDF to do a text-based check, but that is painful

@FaheemMitha Handling what?

@StefanKottwitz Reasonable summary: etoolbox is pretty good as far as it goes, but the need for cs... all over the place shows up the limitations

Faheem Mitha

@JosephWright Just a bit of code I was trying to write:

\newbool{showcountersig}
\setbool{showcountersig}{true}
% \setbool{showcountersig}{false}

\NewDocumentCommand{\CounterSig}{ m O{faheem_sig1_imagemagick.png} }
{
  \ifbool{showcountersig}
  {\node [font=\bfseries, align=center] at #1 {\includegraphics[width=.25\textwidth]{#2}}}
  {}
}

Using \ifbool.

Joseph Wright

@FaheemMitha In the same style, one could use \bool_if:NT with a boolean such as \l__fm_showsig_bool

Faheem Mitha

3:51 PM

@JosephWright I see. Would there be significant differences between the two approaches?

Joseph Wright

@FaheemMitha Not really in this case

Faheem Mitha

@JosephWright Ok.

Faheem Mitha

4:08 PM

So it looks like this Brexit thing is really happening.

Ulrike Fischer

@JosephWright I wonder how stable the binary output is.

Joseph Wright

@UlrikeFischer With the reproducible build stuff set up, they shouldn't change unless one explicitly requests they do. Of course, one might want to just check the tags, but I think that is a job for specialist PDF tools.

@UlrikeFischer We (team) did look at testing 'bits' of PDFs: you can arrange to put markers into the stream and then examine things as text, but to be honest I think that's more useful done manually for set-up, than in automated checks

Ulrike Fischer

@JosephWright I'm wondering about fonts and if there are (small) difference between the various OS. But we will see ...

Joseph Wright

5:06 PM

@UlrikeFischer I'll find out soon enough

yo'

7:48 PM

So, I'm in @PauloCereda's house just now :)

Joseph Wright

@yo' Cool!

yo'

@JosephWright indeed!

Paulo Cereda

@yo' Quack. :)

@JosephWright He is literally in the other side of the room. :)

Faheem Mitha

8:06 PM

@yo' So, does he have lots of pet ducks? I'm thinking a pond.

samcarter

@yo' Did you meet the famous cat? And does the house look like this: en.wikipedia.org/wiki/Big_Duck ?

barbara beeton

8:59 PM

@yo' and @PauloCereda -- hello! have a good time. give arara a good workout.

Alan Munn

@PauloCereda This is a major road in Toronto: goo.gl/maps/U6nmnJkJdxG2

Ulrike Fischer

@barbarabeeton is there are gallery of the various "TUG graphics" (from the TUG conferences) somewhere?

Joseph Wright

@UlrikeFischer Ooh, interesting idea

Ulrike Fischer

@JosephWright my husband -- who is an historian -- asks such questions ;-)

barbara beeton

@UlrikeFischer -- not as such, but most of them are on the covers of the relevant tugboat proceedings issues. (i'll make the suggestion to create a gallery.) but that's only the "official" pictures for the conferences. i think the pictures that were given to various tex "worthies" weren't ever all collected in retrievable form. and i'd really have to dig to identify them all. i'll try.

Joseph Wright

10:13 PM

@UlrikeFischer Indeed, seems there are issues (see github.com/latex3/l3build/issues/10 and github.com/latex3/l3build/issues/21). I suspect the only sensible tests for us will be ones where parts of the PDF can be extracted.
