Yeah, that's what a lot of people see. But that is deceptive.
tcolorbox is a powerful tool for arrangement tasks (the box layouts can be completely hidden).
You can make arrangement tasks difficult with plain-LaTeX methods and cryptic commands; or you can use tcolorbox.

It took me a long time to see this .... Ohhh no ..... once more a new syntax ... after TikZ, pgfplots, pgfplotstable .... But I've rarely bet on the wrong horse.

@AlexG context now uses a new engine which doesn't know the primitive anymore.

AlexG

@UlrikeFischer Good to know. But what comes next (for me to do)?

Ulrike Fischer

@AlexG ask @MarcelKrüger he managed to create a latex format which works with the new engine (I'm on the road currently so can't check code).

For some reason, this solves it:

@AlexG We should have this sorted soon-ish in expl3

@AlexG Welcome to to our world (@UlrikeFischer, @DavidCarlisle, @MarcelKrüger)

@JosephWright , @UlrikeFischer Thank you, but it's a solely context-related problem. Can expl3 help here?

@UlrikeFischer I even checked the documentation for dvipdfm(x) to see if it special cased white before making that comment. I should have known better.

\draw[very thick] ([yshift=\n*\u]B) -- +(-3mm,0) node[left]{

@samcarter_is_at_topanswers.xyz That is a matter of style, no worries :)

samcarter_is_at_topanswers.xyz

@VincentMiaEdieVerheyen (I don't understand why you can't change the clip)

Anonymous

@samcarter_is_at_topanswers.xyz Because then the rulers, if there are 1 on each side (4 in total) overlap very ugly in the corners.

Anonymous

I mean, we have to use

\clip (-0.1,-0.1) rectangle (1.1,1.1);

instead of

\clip (0,0) rectangle (1,1);

to be able to show the rulers outside of the image.

Anonymous

@samcarter_is_at_topanswers.xyz If you clip it there at the top, how would we be able to also have a top-ruler then, at the top side of the image?

samcarter_is_at_topanswers.xyz

13:31

@VincentMiaEdieVerheyen For something similar with numbers, have a look at the tikz user guide for decorations

@VincentMiaEdieVerheyen You could clip only the vertical ruler at one. For the ruler at the top, you could use another clip value

Anonymous

@samcarter_is_at_topanswers.xyz That makes sense! That would be great as well.

Anonymous

@samcarter_is_at_topanswers.xyz Which solution do you think is most elegant, to clip each ruler seperately, or to find the decorate way for the numbers?

samcarter_is_at_topanswers.xyz

@VincentMiaEdieVerheyen I would clip each ruler separately. You can still combine this with decorate if you want

Anonymous

That sounds great! @samcarter_is_at_topanswers.xyz How do I clip only one ruler?

Anonymous

Inside a scope?

samcarter_is_at_topanswers.xyz

13:37

\begin{scope}
\clip (-0.1,-0.1) rectangle (1.1,1.1);

% draw one ruler here

\end{scope}

@VincentMiaEdieVerheyen Yes, exactly

Gaussler

I quote from the l3 manual: “The e specifier is in many respects identical to x, but with a very different implementation. Functions which feature an e-type argument may be expandable. The drawback is that e is extremely slow (often more than 200 times slower) in older engines, more precisely in non-LuaTeX engines older than 2019”

Question: Does that mean that none of this applies to pdfTeX later than 2019?

More precisely, is it still slower than :x?

Skillmon likes topanswers.xyz

@Gaussler No, e is faster than x as long as the \expanded primitive is available.

@Gaussler Another difference is that you don't have to escape #1 with ##1 in e as you'd have to do in x.

Gaussler

13:39

@Skillmonlikestopanswers.xyz So, in all modern engines, you should just go ahead and use it to your heart’s content?

Anonymous

So, perhaps the decorate way is better after all, without any clipping @samcarter_is_at_topanswers.xyz ?

Skillmon likes topanswers.xyz

@Gaussler Well, the LaTeX team is currently trying to use it sparsely or provide fallback code, but in your own code you can use it as much as you like.

samcarter_is_at_topanswers.xyz

@VincentMiaEdieVerheyen Oh, decorate might then be the better choice

Skillmon likes topanswers.xyz

@Gaussler but there is a minor bug in the pdfTeX and XeTeX engines regarding \expanded.

Anonymous

13:41

@samcarter_is_at_topanswers.xyz OK, I will try to copy the text as per this screenshot. Hopefully it will yields something useful.

Skillmon likes topanswers.xyz

@Gaussler This bug shouldn't affect your documents at all, but you'll get an out-of-memory error if you try to run \expanded several hundred times directly after each other (I stumbled upon that during some benchmarking, in a normal document this shouldn't ever be needed as often)

samcarter_is_at_topanswers.xyz

@VincentMiaEdieVerheyen better copy from the user manual then from the screenshot, then you can copy&paste :)

Gaussler

@Skillmonlikestopanswers.xyz I am currently developing my semantex package, which sounds like a place where you might end up doing exactly that

It’s quite expansion-heavy

So I might wait a bit before e’ing too much

@VincentMiaEdieVerheyen \AddToShipoutPictureBG{\put(\LenToUnit{.5\paperwidth}, 0){\makebox[0pt][c]{<stuff>}}} should do.

@VincentMiaEdieVerheyen I misunderstood what you wanted with \myhcenter. That one centres only with respect to the current position, not on the page.

@Skillmonlikestopanswers.xyz Great, this is is great. Thanks.

Now to fiddle with the vspace, I have to use another tabular? xD

I don't think I can put the \begin{tcbitemize} inside a tabular? @Skillmonlikestopanswers.xyz

Oh, I found a way

@Skillmonlikestopanswers.xyz Would you know a way to print text, right-aligned, at the top-right of the page?

like raggedright? to print something on every page?

@MarcelKrüger TeX Live is the usual place

@MarcelKrüger Or just mail it to Karl: in the end, that's what's important

@MarcelKrüger You're fast :D

So maybe there is a better alternative to \begin{tcbitemize} after all, just to divide something into 2 columns?

@DavidCarlisle?

17:49

I am not coming with you.
Can you post a question with a working minimal example on the main page, listing all (remaining) problems?

A few things stand out:
- In my opinion, eso-pic can be avoided completely if tcolorbox is used.

- "Header" and "Footer" can be placed more easily.

@VincentMiaEdieVerheyen sorry not following this at all far too many disconnected fragments to look at.

Anonymous

OK I will try to do that cis. Maybe one of these days. I am still fiddling a bit with the rulers ... perhaps I want to divide them into two seperate boxes, per picture ... I don't know what is the scientific concensus on this ...

By the way, when I export from PDF to GIF using

convert -alpha deactivate -verbose -delay 50 -loop 0 -density 400 paper.pdf file.gif

then even at 400 density, the output is lame

Otherwise: I see, you use eso-pic to generate a "Header" and a "Footer" manually; I think due to you set
`\geometry{paperwidth=15cm, paperheight=30cm}`, so you do not have a header and footer from your documentclass.
Mmmh, ok. Why not.

@MarcelKrüger May I ask what the issue was (not that I know anything about the internals...)

Anonymous

The issue that I describe here https://chat.stackexchange.com/transcript/message/55398619#55398619 is also reported here https://tex.stackexchange.com/questions/247506/how-to-draw-a-bicolor-tcolorbox-without-frame, it is that narrow ghost lines remain when using tcbitemize

i now circumvent this by making everything white ... but this is not ideal

Skillmon likes topanswers.xyz

@VincentMiaEdieVerheyen that message wasn't directed to you but to @MarcelKrüger who had a patch for a bug in two of the TeX engines.

Anonymous

ok :)

Marcel Krüger

@Skillmonlikestopanswers.xyz When TeX stores a token list e.g. for a macro definition, it stores a reference counter prepended to the token list. \expanded used a way of scanning the token list which also prepended the reference counter, but then passed it to the input stack in a way that the reference counter isn't needed. Therefore the reference counter is not tracked by the input handling code. But the expanded code never released the reference counter...

cis

Here I can't say better or worse.

Flat-rate:

tcolorbox is an extensive application that does a lot of calculations for dimensions in the background.

parbox is plain LaTeX style, for whose use you have to have the appropriate dimensions ready or calculate yourself.

Marcel Krüger

18:29

@Skillmonlikestopanswers.xyz The counters are stored in main memory which in TeXLive defaults to 50000000 slots. So after that, the leaked counters occupy the entire allocated allocated main memory.

Skillmon likes topanswers.xyz

@MarcelKrüger ah, I'd have guessed something like that (some allocation in TeXs memory not being freed correctly).

@MarcelKrüger thanks for the explanation!

@cis and @VincentMiaEdieVerheyen I'd say that tcolorbox is that fancy party service that organizes your birthday, \parbox is just a hut in your garden. It gets the job it is made for done perfectly, but nothing more than that.

cis

@Skillmonlikestopanswers.xyz Hehe... :()

It is true that in tcolorbos you sometimes have to fight against given formats or have to turn off auto formats first (such as "forced frames").
On the other hand, the whole thing has a mostly simple syntax.

Anonymous

@cis I see, then I might want to study that package a bit more and learn how to use it well.

I don't understand why C in the following gets printed on a new row, whereas A and B are on the same row, in a different column:

\tcbitem \large A \\
\tcbitem \large B \\
\tcbitem \large C \\
\end{tcbitemize}

@cis oh, these days I look like I don't like tcolorbox, when actually the opposite is the case, I use it in my own documents and like it, I just also like knowing how to do things on your own... And I don't like using tools that do everything, when you don't need everything but just \parbox.... :)

Anonymous

\begin{tcbitemize}[size=tight, halign=center, raster equal skip=0pt, raster width=0.2\textwidth, boxrule = 0pt, frame hidden, colframe=gray, colback=white, colbacklower=gray,
raster left skip=-1mm, raster right skip=-1mm,% including this to solve horizontal alignment issues
]
\tcbitem \large A \\
\end{tcbitemize}

Produces the ghost lines as described in https://tex.stackexchange.com/questions/247506/how-to-draw-a-bicolor-tcolorbox-without-frame

Only if you change everything from gray to white, they will dissapear on a white background ...

Do you have the same?

cis

The ghostlines can partially remain in the preview, depending on the TeX editor (not with my TeXworks).
In the main reading program, e.g. AdobeReader, they should be gone.

Anonymous

@cis If I use GraphicsMagick for example to convert the PDF output to a GIF, they also remain in the GIF output ...

cis

I understand, so you should set
colframe=white,
not colframe=gray as you have done in your MWE.

Anonymous

Yes, I am making all white for now ... but I guess I will have to change all whenever the background would change ... not ideal.

Other than that, the columns are enjoyable now :)

@cis What did you do here please? Help me understand what this is for? :)

And how would I print a footer on a page with \begin{tcbitemize}

cis

@VincentMiaEdieVerheyen This is hard, but the method is used by the author himself:

\documentclass[a4paper, landscape]{article}
\usepackage[showframe=true]{geometry}
\usepackage[most]{tcolorbox}

\begin{document}

\centering\mbox{\begin{tcbitemize}[
%center,
%before=\centering, after=\par\bigskip, % doesn't work at tcbitiemize
%hbox,
size=tight,
raster columns=2,
halign=center, raster equal skip=0pt,
raster width=0.5\textwidth,
boxrule = 2pt,
raster left skip=-1mm, raster right skip=-1mm,% including this to solve horizontal alignment issues
]
\tcbitem \large A %\vspace{1.5em}\\

In my opinion, the simplest would be if the document had a footer, this could be done in the classic way with a page layout package (scrlayer-scrpage)

But since header / footer were turned off with geometry, I would use eso-pic as in the other cases.

@UlrikeFischer what else could I say:-)

@DavidCarlisle you could add a few pictures ;-)

David Carlisle

@UlrikeFischer like that?

cis

@VincentMiaEdieVerheyen Command back!

It is simply `raster halign=center % centers the whole environment`

\documentclass[a4paper, landscape]{article}
\usepackage[showframe=true]{geometry}
\usepackage[most]{tcolorbox}

\begin{document}
\begin{tcbitemize}[
raster halign=center, % centers the whole environment
size=tight,
raster columns=2,
halign=center, raster equal skip=0pt,
raster width=0.5\textwidth,
boxrule = 2pt,
raster left skip=-1mm, raster right skip=-1mm,% including this to solve horizontal alignment issues
raster equal height=rows, % <--- Maybe wanted
]
\tcbitem \large A \vspace{1.5em}\\ a%<-- this is expanded inside the item

PS: If there is a use of \mbox{....... or \centering or .....
due to a tcolorbox one should become skeptical; because normally there are keys that set something like that.

Ulrike Fischer

@DavidCarlisle perfect ;-)
