https://tex.stackexchange.com/questions/681271 | 1 | How can I make a right "hanging" from last line of a paragraph?
This is useful for tables of content and indexes with long entries.
The following is an example of what I need:
```
Lorem ipsum dolor sit amet ........................... 123
Lorem ipsum dolor sit amet, consectetuer adipiscing
elit. Ut purus elit, vestibulum ut, placerat ac
adipiscing vitae, felis. Curabitur dictum gravida
mauris. Nam arcu libero, nonummy eget, consectetuer
id, vulputate a, magna. .............................. 456
Lorem ipsum dolor sit amet ........................... 789
```
At the moment I'm using the following. But it justifies the text and the numbers at the same right position:
`\par\noindent\raggedright very long text \dotfill 456`

My goal is to align all values based on the decimal points, but I am struggling with the parentheses in the *B* and *\beta* columns. If possible, I would like to avoid splitting the values in parentheses into an additional column.
So far, I have tried `S[table-format=1.2 (1.2)]` but it did not work in the desired way (i.e., no space between parenthesis and preceding number, no decimal point).
Any help is greatly appreciated!
| https://tex.stackexchange.com/users/293998 | Parentheses in siunitx table | true | When you set `uncertainty-mode` to `full`, `siunitx` prints uncertainties as they are provided. In order to insert a gap between quantity and uncertainty, you can reformat `output-open-uncertainty`.
You should not resize tables. Rather try to decrease font size. IMO if you have to set a font lower than `\footnotesize`, it probably means your table needs to be redesigned. I also split your table into two parts in order to apply two slightly different formatting; `Num. Obs.` is an integer and should not be formatted; Hence, I enclosed all integers within two braces `{...}`.
In general, the whole table could be rearranged. The lower part seems like a separate table anyway. If you exclude it from the upper part, then you could move the groups `Variable X` to separate rows and repeated `Intercept`, `Predictor A`, ad n`Predictor B` for each group. That way, you could even fit the table horizontally. Currently, I had to use `sidewaystable` and render the table vertically to fit it in a page.

EDIT to render table horizontally.
First, consider adding the following snippet to preamble to see a frame denoting text boundaries
```
\usepackage{showframe}
\renewcommand*\ShowFrameLinethickness{0.2pt}
\renewcommand*\ShowFrameColor{\color{blue}}
```
I added code with two versions of the table.
If you have to resize it, beware the effect is degrading and is more visible the greater is a scale factor.
I would first make sure everything is minimised including font, column widths, spaces etc.
Then, I would apply `resizebox`.
Here's the first non-scaled version of the table exceeding left and right margins
The second scaled version fits the page.
Everything has been reduced to minimum so negative effects of `resizebox` are also reduced.
In the code, I have moved `tabular`s to saved boxes in order to measure their width.
This is not required if you decide on a scaled version because you will not need to apply negative space.
Just move everything back to the `table` environment.
```

$pdflatex = 'xelatex -synctex=1 --interaction=nonstopmode -shell-escape -file-line-error %O
```
| https://tex.stackexchange.com/users/206194 | Nomenclature not showing using vimtex / latexmk compilation set-up | true | Your `main.tex` has an error, the line
`\ifstrequal{#1}{O}{Other symbols}{}}}%`
has an extra `}` at the end and should be
`\ifstrequal{#1}{O}{Other symbols}{}}%`.
`\RR` is also not defined, so I've added `\newcommand\RR{RR}` but probably you want to load a package.
Your `.latexmkrc` appears to have a dodgy `$pdflatex` call, we also want to replace the `glo` and `gls` with `nlo` and `nls` as
```
@cus_dep_list = (@cus_dep_list, "nlo nls 0 makenomenclature");
sub makenomenclature {
system("makeindex $_[0].nlo -s nomencl.ist -o $_[0].nls"); }
@generated_exts = (@generated_exts, 'nlo');
$pdflatex = 'xelatex --synctex=1 --interaction=nonstopmode --shell-escape --file-line-error %O %S'
```
This then compiles on the command line with `latexmk -pdf main.tex` (requiring `-pdf` as otherwise `latexmk` appears to default to `latex`).
I don't think this `$pdflatex` line is the preferred way to call `xelatex` though, it overwrites `latexmk`'s `pdflatex` and hardcodes flags (fixing `--shell-escape` active is not a great idea). You can just do
```
latexmk -xelatex [flag options to xelatex] file
```
I haven't tested with neovim/vimtex, but it looks like your `latex.lua` does exactly that, in which case
main.tex
```
\documentclass{memoir}
\usepackage{nomencl}

\newcommand\RR{RR}

sub makenomenclature {

@generated_exts = (@generated_exts, 'nlo');
```
should work if you trigger compilation within vimtex. If this doesn't work, try without `build_dir = 'build',` in `latex.lua` first, the `makeindex` call may need to be adapted to take account of the `build_dir`.

I made the following changes:
1. added the `enumitem` package, so you can use the `resume*` option in subsequent `enumerate` occurrences without having to reset the counter
2. changed the number of variables in your `abox` to just one for the title. You don't need to define a variable for the content of the box
3. removed all superfluous brackets as a result of that change
4. added the option `nofloat` to your box definition as you clearly stated you don't want the box to be a floating object
5. removed the `center` environment as that is no longer required to prevent floating
6. since the caption is following the box, but not attached to it, you need to add some vertical space to increase the distance between caption and next paragraph. You can't use the option `before / after skip balanced` from `tcolorbox` (see pages 86-88 in the manual)
The result of these changes:
As to why the vertical spacing is altered at the first `enumerate` when embedded in a `center` environment, I have no clue.

Assuming the work was cited on pages 1, 2 and 3, `backrefstyle=two,` therefore compresses the pages to "1-3" as advertised.
There is also `backrefstyle=three,` which only compresses ranges of three or more, but even that does not help you here. The only option that comes close to you what you want in this instance is `backrefstyle=none,`.
If the only thing you need in addition is an "and" before the last page, you may want to try switching the list format for `pageref` from `list:plain` to `list:delim`.

| https://tex.stackexchange.com/users/260816 | How to make sections in a bibliography | true | To create a bibliography with sections in LaTeX, you can use the `biblatex` package with custom categories for each section. Here's an example:
1. First, install the biblatex` package in your preamble:

\usepackage[backend=bibtex,style=numeric,sorting=none]{biblatex}
```
2. Define your categories:
```
\DeclareBibliographyCategory{historical_review}

```
3. Assign bibliography entries to their respective categories:
```
\addtocategory{historical_review}{Chap0-Handbook,Chap0-RUNGE}
\addtocategory{monitoring}{Chap1-Christodoulopoulos}

**EDIT**: AS @louis wants an example for a way to have the bibliography items inside LaTeX-script here is a solution:
You can create a custom bibliography with sections directly within your LaTeX document using the `enumitem` and `hyperref` packages. Here's how:
1. First, add the `enumitem` and `hyperref` packages to your preamble:
```
\usepackage{enumitem}
\usepackage{hyperref}
```
2. Create a custom bibliography list:
```
\newlist{bibsection}{enumerate}{1}
\setlist[bibsection]{label={[\arabic*]},itemsep=0.5\baselineskip,leftmargin=*,align=left}
```
3. Define your bibliography items within sections:
```
\begin{bibsection}
\section*{Historical review of capacity in optical telecommunication networks}
\item B. Mukherjee et al.,
\textit{Springer Handbook of Optical Networks},
Springer Cham, 10/2020,
ISBN: 978-3-030-16249-8,
\href{https://doi.org/10.1007/978-3-030-16250-4}{doi:10.1007/978-3-030-16250-4}
\item P.K. Runge,
\textit{An experimental 50 Mb/s fiber optic PCM repeater},
Trans. Comm., Vol COM-24, No. 4, 04/1976,
\href{https://doi.org/10.1109/TCOM.1976.1093308}{doi:10.1109/TCOM.1976.1093308}
\section*{Monitoring in optical networks}
\item K. Christodoulopoulos et. al,
\textit{Toward efficient, reliable, and autonomous optical networks:

IEEE J. Opt. Commun. Netw., Sept. 2019, Vol 11, No. 9,
\href{https://doi.org/10.1109/JLT.2020.2984270}{doi:10.1109/JLT.2020.2984270}
\end{bibsection}
```
This code snippet creates a custom enumerated list for your bibliography and separates the items by sections. The result is a bibliography that resembles the one in your original question, without the need for a `.bib` file.
Tough, I would highly recommend to outsource the `.bib` file whenever possible. This makes debugging much easier and might help to keep the original document file in a more structured way!
EDIT II : It seems their was a misunderstanding regarding the question. The following solution provides a way to add a custom Reference section, while creating custom bibitems.
To create a custom bibliography with sections in LaTeX without using a `.bib` file, you can use the `etaremune` package for reverse enumeration and the `hyperref` package for clickable DOIs. Here's how:
1. Add the `etaremune` and `hyperref` packages to your preamble:
```
\usepackage{etaremune}
\usepackage{hyperref}
```
2. Create custom commands for easy citation and reference:
```
\newcommand{\customcite}[1]{[\ref{#1}]}

---
I am using the following command line to rotate a line that I use to dimension the radius of a circle, as mentioned in an answer to [the above mentioned](https://tex.stackexchange.com/questions/88913/how-to-label-or-dimension-a-circle-radius-in-tikz) post:
```
\draw[-latex, rotate around={45:(0,0)}] (0,0) -- (6,0) node [midway,fill=white] {$\text{Text}$};
```
The problem is, I am not using `(6,0)` but a point `(p)` that is calculated with polar coordinates. As soon as I replace `(6,0)` by `(p)`, the rotation doesn't work.
---
How do I workaround the fact that `rotate around` apparently doesn't work for points in polar coordinates?
---
Edit: I added the exact code I used to calculate the point with polar coordinates (it's called `last1`):

| https://tex.stackexchange.com/users/209759 | Dimensioning the radius of a circle: `rotate around` doesn't work with polar coordinates? | true | I have to admit that it took me a while to get what you mean, so I try to restate it with my own words:
The problem is that `\draw[-latex, rotate around={45:(0,0)}] (0,0) -- (4,0);` would work (the resulting line is rotated by 45 degrees). Similary, `\draw[-latex, rotate around={45:(0,0)}] (0,0) -- (0:4);` would work. But as soon as you replace one of the coordinates of your path with a previously defined coordinate, the transformation does not work anymore. So `\draw[-latex, rotate around={45:(0,0)}] (0,0) -- (last1);` would actually not result in a rotated line, although the coordinate `(last1)` is defined as `(0:<x>)`.
This problem seems to be the same as in [this other question](https://tex.stackexchange.com/q/98924/47927%5D). The reason for this is that the coordinate was defined outside the scope of the transformation (in fact it is not exactly a scoping issue but a feature that applies an inverse transformation on anchor points and which is quite sensible in most cases\*; thanks to Qrrbrbirlbel!). I can actually understand that this behaviour is quite peculiar, at least not directly obvious.
So, what you need to do is to explicitly transform the previously defined coordinate. Since the other coordinate of your path is `(0,0)`, you don't need to transform the rest of the path: You can write `\draw[-latex] (0,0) -- ([rotate=45]last1);` and will get a line rotated by 45 degrees.

| https://tex.stackexchange.com/users/24406 | Rotation of letter which aligns with the text line? | true | An improvement to Sebastiano's fine answer.
The rotated “e” should, in my opinion be sligthly nudged up and a small kern added to the right.
If you look the “be” example, you see that the space between the two letters is larger than between the simply rotated “e” and the “e”.
The other problem is that “e” overshoots the x-height and we need to move it up a bit to compensate.
```

Different shifts might be needed with other fonts. Here the same parameters are used with `ebgaramond`.
Here we see that “e” overshoots both the x-height and the baseline; moreover the kerning doesn't seem necessary. With
```
\raisebox{-0.01ex}{...}
```
and no final kern we get

https://tex.stackexchange.com/questions/681346 | 1 | I converted a font some time ago and now there is an update to this font. As the new font files are provided by a different company, there are slight differences, especially with symbols. However I figured out all differences in the glyph positions and set them up accordingly in a modified encoding file. There is a problem however: When I try to access the symbols, e.g. through `\textuparrow` PDFtex tells me:
```
Package textcomp Info: Symbol \textuparrow not provided by
(textcomp) font family MYFONT-TLF in TS1 encoding.
(textcomp) Default family used instead on input line 525.
```
But when I put a simple
```
\DeclareTextSymbolDefault{\textuparrow}{TS1}
\DeclareTextSymbol{\textuparrow}{TS1}{94}
```
in the preamble, PDFtex does not complain anymore.
What am I doing wrong here, what sort of misconception do I have and what can I change to make this work without adding the above code to my MYFONT.sty file as manual definitions? I checked `textcomp.sty` which has this strange `\tc@check@symbol2` in front, is this maybe my issue:
```
\DeclareTextCommandDefault{\textuparrow}%
{\tc@check@symbol2\textuparrow}
```
As `ts1enc.def` just goes straight with:
```
\DeclareTextSymbol{\textuparrow}{TS1}{94}
```
| https://tex.stackexchange.com/users/156791 | Why does textcomp not load the glyph from my font but replaces it? | true | As pointed out in <https://ctan.math.washington.edu/tex-archive/macros/latex/base/ltnews36.pdf> referencing to <https://www.latex-project.org/help/documentation/fntguide.pdf> since 2021/06/01 one must declare which subset of glyphs is contained in a TS1 encoded font.
So based on the respective subset, one can select e.g. `\DeclareEncodingSubset{TS1}{MYFONT-*}{1}` or any other number as appropriate.

Inspect the mwe.log file. Notice that `fontspec` by itself does not load `luatexbase`.

```
\sys_if_engine_luatex:T{
\RequirePackage{luatexbase} % already included by fontspec, but needed here
\RequireLuaModule{polyglossia}
}
```
Apparently, "already included by fontspec" is incorrect.
Or is there something I do not grasp?
How I discovered this: I have been playing around with code from various packages,
to see what they do. I came across `priority_in_callback` which is in `luatexbase`.
Interestingly, there are other references to `luatexbase` that work, even when
`luatexbase` is not loaded! That is a mystery.
| https://tex.stackexchange.com/users/287367 | polyglossia loads luatexbase | true | That comment was true when written. But post 2015, most of luatexbase was renamed and recoded as ltluatex and included in to the format so fontspec does not need it. All the Lua parts of ltluatex are in a module still called `luatexbase` for compatibilty.
The current `luatexbase` package is re-written to mostly be `ltluatex` which is pre-loaded by the format, but defines a few extra functions for compatibility with the original version of the package.

https://tex.stackexchange.com/questions/681364 | 3 | I got it from [overleaf](https://www.overleaf.com/learn/latex/Multi-file_LaTeX_projects#The_subfiles_package) that the `subfiles` package is best loaded last in the preamble.
Besides, it is known that hyperref is recommended to loaded last too. In another [answer](https://tex.stackexchange.com/a/53193/292473), I got that
>
> Load `varioref` first, then `hyperref`, then `cleveref`
>
>
>
so what's the best or recommended order to load these packages mentioned above?
| https://tex.stackexchange.com/users/292473 | The best/correct order of loading hyperref, cleverref and subfiles packages | true | Recommended order for the packages you mentioned:
`Subfiles` - This package should be loaded first. It is designed to help manage multi-file LaTeX documents by allowing you to compile each file individually as well as the main document as a whole. So it's generally a good idea to load the subfiles package first so that it can properly handle any subfiles included in the document.
In addition, subfiles doesn't typically interact with the other packages you mentioned (cleveref, hyperref, and varioref), so its position in the loading order should not affect their behavior.
If you are using subfiles to manage a multi-file document, it is important to load it before any packages that modify the way files are included or referenced, such as `xr` or `import`.
`Varioref` - This package should be loaded first, as it modifies the way LaTeX handles cross-referencing.
`Hyperref` - This package should be loaded after varioref, as it also modifies cross-referencing and creates hyperlinks in the document. It is normally loaded last, but due to cleveref it is not.
`Cleveref` - This package should be loaded last, as it depends on both varioref and hyperref. It provides additional features for cross-referencing, such as automatic formatting of reference types.
If you look at the [`cleveref` guide](http://tug.ctan.org/tex-archive/macros/latex/contrib/cleveref/cleveref.pdf#page=25):
>
> The following are not bugs. They are either intentional behaviour, unavoidable

But now I would like to add to the code or have the option of selecting a title image in the presentation.tex file, which is automatically adapted to the frame and of course also to the selected aspectratio.
In other words, in the presentation.tex e.g.. For example, the command:
`\titlepicture{file}`
and it automatically appears in the right place via innertheme.

https://tex.stackexchange.com/questions/681376 | 1 | The package hf-tikz is great for putting a frame around an equation. Although I am not absolutely sure there seems to be a "new" error massage when using this package: "Missing character: There is no ; in font nullfont!"
I stripped my complex beamer-file down to actually a minimal LaTeX-file which also gives the error message:
```
\documentclass{article}
\usepackage{hf-tikz}
% \font\nullfont=cmr10
\begin{document}
\begin{displaymath}
\tikzmarkin{eq}
c^2 = a^2+b^2
\tikzmarkend{eq}
\end{displaymath}
\end{document}
```
The resulting PDF-file is ok with no errors, but the error message makes me a bit nervous because the question is always what happens after the next update? My system is a MINT Linux 21.1 with an underlying Ubuntu 22.04 and a full installation of Texlive 2022.
If I uncomment the line "% \font\nullfont=cmr10" a semicolon appears at the end of the coloured box. From other postings about the "Missing character..." error message I learned that setting the nullfont to a visible font allows to find the error in the underlying LaTeX code. It seems that there is an error in the package hf-tikz or that the syntax of tikz has changed a little bit and the older package hf-tikz has not been adapted to these changes.
Any idea how to overcome the problem?
| https://tex.stackexchange.com/users/294065 | LaTeX-Package hf-tikz: Error message "Missing character: There is no ; in font nullfont!" | true | In this case the message is harmless. It was always in the log but appears now also on the terminal because `\tracinglostchars` has been set to 2 in a current LaTeX.
But it would be better if hf-tikz would avoid it by delimiting the `\tikz` arguments by braces instead of using the semicolon syntax, as with it there is always the danger to end up with one stray semicolon too much:
```
\documentclass{article}
\usepackage{hf-tikz}
\renewcommand\tikzmarkend[2][]{%
\tikz[remember picture with id=#2]{#1}} %{#1} instead of #1;
\begin{document}
\begin{displaymath}

| https://tex.stackexchange.com/users/234365 | Problem with equation inside figure | true | As @samcarter\_is\_at\_topanswers.xyz has already noted in a comment, blank lines aren't allowed in a display math environment. The fact that your test document supposedly compiles successfully on Overleaf is almost certainly due to Overleaf doing an excellent [!] job hiding LaTeX warning and other messages from users.
I'd go further than just eliminate the blank lines, though. Specifically, I'd (a) use inline math mode instead of display math mode and (b) employ a `tabular` environment instead of an `array` environment because the words in the 4x3 array should be typeset in text mode, not math mode.
A separate issue: Is it essential that the tabular/array material be surrounded by round parentheses? Would simple vertical lines on either side of the tabular/array material do just a well? If so, you could get rid of the math-y setup entirely and replace `\begin{tabular}{lll}` with `\begin{tabular}{|lll|}`, as is demonstrated in the lower half of the following screenshot. (For that matter, does the table really need to be surrounded by either parentheses or vertical lines?)

https://tex.stackexchange.com/questions/385399 | 1 | I am trying to draw a Cayley graph for Z\_8 and need some arrows.
My problems :
1. The names of nodes come exactly on the coordinators, is there a way of setting it to appear beside the coordinator not on it. Or, how can I move it manually up and down?
2. Because I fullback the nodes, the tips of arrows don't appear clearly. How can I solve it, even If I had to put the tip in the middle of the arrow.
I appreciate any help or suggestions.

https://tex.stackexchange.com/questions/681400 | 1 | In a beamer presentation I am using `\footcite{}` in order to give some citations. Unfortunately, I have recognised the following problem which I am not able to solve:
I have a slide containing multiple overlays and only a single citation, i.e.
```
\begin{frame}
\frametitle{<Title>}
\visible<1->{
Some text with a citation\footcite{citekey}
}
\visible<2->{ Some more text whithout a citation
}
\visible<3>{
again some more text
}
\end{frame}
```
When I look at the slides I have the following citation in the first overlay:
>
> CITENUMBER AUTHOR “TITLE”. In: BOOK, Page..
>
>
>
The Authors and the title of the book are highlighted in blendedblue (beamer standard).
But on the next overlay (i.e. same slide) I only have
>
> CITENUMBER AUTHOR “TITLE”
>
>
>
and nothing is highlighted in blendedblue here.
So, any idea how to ensure that citations are equal on every overlay?
| https://tex.stackexchange.com/users/294085 | Beamer \foocite{} and multiple overlays leads to multiple citation styles | true | You can avoid the problem by using `\footfullcite` instead of `\footcite`. This will ensure that biblatex will always print the full citation.

| https://tex.stackexchange.com/users/13009 | How to display the footnote in the bottom of the slide while using \columns? | false | I had the same problem, and I'm using pandoc so I wanted the solution to work by default on all footnotes with a `renewcommand` (just as asked by @jadelord in a comment below @andreas post). But it is nothing simple, because of all the layers that beamer adds to `footnote` and `renewcommand` in order to manage overlay specifications (and pandoc sends an overlay specification to `footnote`). Ideally, the pandoc code should be updated. The only solution I found is to copy/paste the `footnote` `renewcommand` from beamer source code and force the `frame` option. Here is my code for the record.
```

Please help!
| https://tex.stackexchange.com/users/18624 | Missing $ inserted issue | false | If you are handling complex tex when using new packages might incur even more problems, I find a simple solution by replacing the underscore in the bib files' DOI link with `\textunderscore`, like this:
```
doi = {10.1007/978-3-319-45738-3\textunderscore9}
```
It should solve your issue in a second.

https://tex.stackexchange.com/questions/681168 | 1 | Is there a way to get in a `NiceTabular` the text stretched up to the column width?
```
\documentclass{beamer}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{wl{20em}}
Sunt cumque voluptatem quasi \\
quam commodi culpa quaerat sunt
\end{NiceTabular}
\end{document}
```
I know about `\makebox[\mywidth][s]{my text}` but isn't there any simpler solution with tabulars?
As I often use `tikz`, the solution should also work with `\node`. `NiceTabular` does well.
| https://tex.stackexchange.com/users/145290 | NiceTabular with stretched text | false | **EDIT**
With the latest version of `nicematrix` (v. 6.17 of 2023/03/31), you can use in `{NiceTabular}` the columns standard columns `w{s}{...}` and `W{s}{...}` (of the package `array`) with the expected output.
```
\documentclass{beamer}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{w{s}{20em}}
Sunt cumque voluptatem quasi \\
quam commodi culpa quaerat sunt
\end{NiceTabular}
\end{document}
```
The output is the same as with `{tabular}` (see below).
---
You probably want to use the column type `w{s}{...}` of `{tabular}` (as defined by the package `array`).
```
\documentclass{beamer}
\usepackage{array}
\begin{document}
\begin{tabular}{w{s}{20em}}
Sunt cumque voluptatem quasi \\
quam commodi culpa quaerat sunt
\end{tabular}
\end{document}
```
Since `{NiceTabular}` of `nicematrix` is an extension of `{tabular}` (of `array`), the same should work with `{NiceTabular}`. However, it does not. That may be considered as a bug. I will try to solve that bug (I'm the author of `nicematrix`).

https://tex.stackexchange.com/questions/681418 | 44 | I'm currently reading [Sparks of Artificial General Intelligence: Early experiments with GPT-4](https://arxiv.org/pdf/2303.12712.pdf). This paper by Microsoft employees experiments with the capabilities of GPT-4, a successor of ChatGPT. One task is to draw a unicorn with tikz.ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
They claim:

Who wants to prove them wrong?
edit: Please don't include PNG / JPG / other pixel image formats. MS-SPO is the only one allowed to do that (as a grandfathering-rule) - kudos for finding the loophole in this question and for thinking outside of the box

The same code without changing anything in it works perfectly in the entirely book code I'm working on. I just copied that section from the book code to create a minimum working example for another question and was stuck by the pgf Error. So I can't ask the real target question yet.

\begin{exercice}\label{exercice:deterministeVersNonDeterministe}
Transformez l'automate non déterministe \code{A = (Q,$\Sigma,\delta$,s,F)} de la figure~\ref{exemple:afnd} en un automate fini déterministe \code{A' = (Q',$\Sigma',\delta'$,s',F')}.\\
Construction de l'automate fini déterministe \code{A'}:\\
\begin{enumerate}
\item Si \code{Q} $= \{1, 2, 3\}$ est l'ensemble des états de l'automate \code{A} alors:\\
\code{Q'} est l'ensemble des sous ensembles de \code{Q}.\\
\code{Q'} $= \{\varnothing, \{1\}, \{2\}, \{3\}, \{1,2\}, \{1,3\}, \{2,3\}, \{1,2,3\} \}$.\\
\item $\Sigma$ ne change pas. Donc $\Sigma' = \Sigma$.
\item Si $\delta$ est la fonction de transition de \code{A}, alors $\delta'$ est la fonction de transition de \code{A'}. $\delta'$ est la fonction de transition suivante, et est un sous ensemble de \code{Q'} $\times \Sigma \times$ \code{Q'}:
\begin{multicols}{2}
$\delta = \{\\
\delta(\varnothing, a)=\varnothing$\\
$\delta(\{1\}, a)=\varnothing$\\
$\delta(\{2\}, a)=\varnothing$\\
$\delta(\{3\}, a)=\{1,2\}$\\
$\delta(\{1,2\}, a)=\varnothing$\\
$\delta(\{1,3\},a)=\{1,2\}$\\
$\delta(\{2,3\},a)=\{1,2\}$\\
$\delta(\{1,2,3\}, a)=\{1,2\}$
\columnbreak
\vline \hspace{1cm}
$\delta(\{\varnothing,b\})=\varnothing$\\
$\delta(\{1\},b)=\{2,3\}$\\
$\delta(\{2\},b)=\varnothing$\\
$\delta(\{3\},b)=\varnothing$\\
$\delta(\{1,2\},b)=\{2,3\}$\\
$\delta(\{1,3\},b)=\{2,3\}$\\
$\delta(\{2,3\},b)=\varnothing$\\
$\delta(\{1,2,3\},b)=\{2,3\}\}$
\end{multicols}
\item \code{s} ne change pas. \code{s} étant l'état initial de \code{A}, il demeure l'état initial de \code{A'}. Si \code{s'} est l'état initial de \code{A'}, alors \code{s' = s = 1}.
\item \code{F} étant l'ensemble des états finaux de \code{A} alors \code{F'} est l'ensemble des états finaux de \code{A'}.
Les états finaux du nouvel automate \code{A'} sont tous des sous ensembles des états contenant l'état $3$.
Donc \code{F'} $= \{\{3\},\{1,3\},\{2,3\},\{1,2,3\}\}$\\
D'où le diagramme des transitions suivant:
\begin{center}
\begin{tikzpicture}[>=Stealth, shorten >=1pt, auto, node distance=2.5cm, initial text = Début]
\node[state](2)[right=of 1]{$\varnothing$};
\node[state, accepting](3)[right=of 2]{$3$};
\node[initial, state](4)[below=of 1]{$1$};
\node[state](1)[above left=of 4]{$2$};
\node[state, accepting](5)[right=of 4]{${\{2, 3\}}$};
\node[state](6)[right of=5]{${\{1, 2\}}$};
\node[state, accepting](7)[below=of 5]{${\{1, 3\}}$};
\node[state, accepting](8)[below=of 6]{${\{1, 2, 3\}}$};
\path[->] (1) edge node {a} (2);
\path[->] (1) edge [swap] node {b} (2);
\path[->] (2) edge [loop above] node {a, b} (2);
\path[->] (3) edge node {b} (2);
\path[->] (3) edge node {a} (6);
\path[->] (4) edge node {a} (2);

\path[->] (7) edge node {b} (5);
\path[->] (7) edge node {a} (6);
\path[->] (8) edge node {a} (6);
\path[->] (8) edge node {b} (5);
\end{tikzpicture}
\end{center}
Si on supprime les états qui ne peuvent être atteints, on obtient l'AFD suivant:
\begin{tikzpicture}[>=Stealth, shorten >=1pt, auto, node distance=3cm, initial text = Début]
\node[initial, state](A){$\{1\}$};
\node[state](B)[above right=of A]{$\varnothing$};
\node[state, accepting](C)[below of=B]{$\{2, 3\}$};
\node[state](D)[right of=C]{$\{1, 2\}$};
\path[->] (A) edge node {a} (B);
\path[->] (B) edge [loop above] node {a, b} (B);
\path[->] (A) edge node {b} (C);
\path[->] (C) edge [bend right] node {a} (D);
\path[->] (C) edge node {b} (B);
\path[->] (D) edge [bend right] node {b} (C);
\path[->] (D) edge node {a} (B);
\end{tikzpicture}
Le langage que cet automate accepte est le suivant:\\
\begin{center}
$\{b(ab)^n$ : $n \in \mathbb{N} \, \}$
\end{center}

| https://tex.stackexchange.com/users/5645 | Draw a unicorn in TikZ | false | You can view the following code from two perspectives:
1. as a cheap trick
2. as an inventive solution.
---
Ad #1: That view should be obvious.
---
Ad #2: It provides the properties of an inventive solution:
* it IS TIKZ
* AND it IS NOT-TIKZ
* i.e. it's a resolution of a contradiction
* done by separation in code
* which can be perceived as the principle of "separating between part and whole" (overall it's tikz as a whole, but not-tikz in it's part(s))
Take that, AI ...

| https://tex.stackexchange.com/users/5645 | Draw a unicorn in TikZ | false | Approach:
* find a drawing
* digitize it, i.e. draw relevant coordinates and lines
* artistic touch: use thicker lines
Some directions for further improvements:
* modify arrow tips, e.g. triangular or curved
* use some kind of fill or texture, e.g. to mimick charcol strokes
* do some fine tuning, e.g. for the ears

https://tex.stackexchange.com/questions/681440 | -1 | I would like to set it in my beamertheme.sty so that when using enumerate or itemize, the symbols are dashes (--) by default. Unfortunately, I have not found a hint in the beamer documentation (chapter 12.1). Is there an additional package I can use for this, or have I missed an option?

https://tex.stackexchange.com/questions/669436 | 1 | Does anybody know how to plot a non-central t distribution using `pst-fun` from pstricks or tikz. For the central t, `pst-fun` has the function `psTDist`, but I can find a way to add a $\delta$ ncp to it.
For the central t is quite straigt foward:
```
\documentclass[border=5mm]{standalone}
\usepackage{pst-plot,pst-func}
\begin{document}
\psset{xunit=1cm,yunit=7.5cm}
\begin{pspicture}(-5.25,-0.05)(5.25,0.5)
% Valor de corte z
\newcommand\z{1.3}
%Dist
\psTDist[nue=9,yunit=1]{\z}{4}
\end{pspicture}
\end{document}
```
I wonder if I need just to generate the non-central t-distribution and plot the points overlapping.

https://tex.stackexchange.com/questions/681452 | 13 | I recently noticed that a new primitive, `\deferred`, was added to luatex ([relevant texlive git changes](https://github.com/TeX-Live/texlive-source/commit/c8ef93f19a2564ae4ea8b6f2bb435329f8322f7a#diff-acfe7b8f6b0f56936b13e5e55fc424a41e171309fe34ae151ef2c5aa92e3380b)). The [luatex manual](https://tug.org/svn/texlive/trunk/Master/texmf-dist/doc/luatex/base/luatex.pdf?revision=65866&view=co) is austere in its examples and explanations for most things, and I see essentially nothing about `\deferred` other than a mention as a *prefix* on page 47 (not sure if this is the same thing) and its appearance in the big list of primitives on page 207.
What does `\deferred` do? My naïve guess based on the git changes is that it's some counterpart to [`\immediate`](https://tex.stackexchange.com/q/20444/208544), possibly related to the new "late special" feature. Beyond what it does, does anyone have an example document in which the new primitive is used to do something not previously possible?
**P.S.** If your texlive is not new enough, you can see that it is actually a proper "command" with [this example](https://texlive.net/run?%25%20!TEX%20lualatex%0A%5Cdocumentclass%7Barticle%7D%0A%5Cbegin%7Bdocument%7D%0Aabc%20%5Cdeferred%7B%7D%0A%5Cend%7Bdocument%7D) on texlive.net.

I think it means, for example
* `\pdfextension literal shipout direct {<tokens>}` (using the new option `shipout`) and
* `\deferred\pdfextenion literal direct {<tokens>}` (using the new primitive `\deferred` acting as a prefix)
do the same thing.
Thus perhaps in LuaTeX Reference Manual it's better to use `\deferred` instead of the current `deferred`.

| https://tex.stackexchange.com/users/5645 | Draw a unicorn in TikZ | false | Approach:
* prepare a (simple) pixelated drawing
* place nodes like pixels, filled with some color
Details:
* most colors predefined
* `\pix` introduced as shorthand notation
* shown: classical lines with `\node ... {};`
* later: shorthands, with `;` being absorbed: `\pix{}{}{}`
Some ideas for refinement:
* node shapes yould be circle, triangle etc. to modify the pixels appearance
* pixels of same color could be placed by `for` loops
* a row or column of colored pixels could be coded for programming and decoded for drawing by tikz

https://tex.stackexchange.com/questions/681395 | 3 | I have been trying to use `\flushbottom` in my documents instead of the lazy `\raggedbottom` to produce documents with higher typographic quality (hopefully). I am wondering if there is a parameter similar to `\tolerance`, but for deciding page breaks.
I want LaTeX to do the following regarding page breaking (or maybe I think I do): If the page cannot be filled, then LaTeX should attempt to fill it by (1) maximally stretching/shrinking the vertical glue no more than its max stretch/shrink and (2) after doing (1), page break at that point even if it leaves extra white space at the bottom of the page.
The closest solution to this issue that I've found involves adding flexible vertical glue on the bottom of page, but that isn't quite what I would like.
[Avoid parskip overstretching](https://tex.stackexchange.com/questions/612098/avoid-parskip-overstretching)
| https://tex.stackexchange.com/users/278534 | Is there a parameter like "vertical" \tolerance? | true | Interesting puzzle, but not impossible to solve.
It is true that there is no vertical tolerance because pages are cut off the scroll one by one, but we can determine the badness of each page made this way. And what you are asking for is that the badness is not exeeding 100.
LaTeX doesn't offer hooks into that part of the output routine, but here is a little implementation that implements your rule:
```
\documentclass{article}
\usepackage{kantlipsum}
\flushbottom
\setlength\textheight{8\baselineskip}
%\showoutput
\AddToHook{cmd/@makecol/before}{%
\setbox0\vbox to\ht255{\unvcopy255}%
\typeout{==> Badness of this page body: \the\badness}%
\ifnum \badness > 100
\typeout{===> ... setting ragged}%
\setbox255\vbox{\unvbox255 \vfill}%
\else
\typeout{===> ... ok}%
\fi
}
\begin{document}
\kant[1][1-4]
\kant[2][1]
\kant[3][1]
\kant[4][1]
\kant[5][1]
\kant[6][1]
\end{document}
```
The badness is calculated as 100 times the cube of the the ratio by which the glue has to stretch or shrink, so 100 means it has stretched less or equal to the amount it is allowed to stretch.
However, you will find that this is way too conservative, you should probably allow for stretching twice or even more (2.5/3?) than that, so a value of 800 or 1600 or ... is more appropriate.
---
Actually, rereading your rule: you want to apply the stretch to the maximum and then fill, so it gets a little more complicated. In that case you would need to also measure the natural height of 255 without stretch, and then use that to figure out how much space is missing that you need to fill and the badness value to figure out how much glue you need to add at the bottom to get to a badness of 100 (instead of simply using `\vfill`as I did above). Excerise for the reader :-)

| 25 | https://tex.stackexchange.com/users/47927 | 681468 | 316,186 |
https://tex.stackexchange.com/questions/681452 | 13 | I recently noticed that a new primitive, `\deferred`, was added to luatex ([relevant texlive git changes](https://github.com/TeX-Live/texlive-source/commit/c8ef93f19a2564ae4ea8b6f2bb435329f8322f7a#diff-acfe7b8f6b0f56936b13e5e55fc424a41e171309fe34ae151ef2c5aa92e3380b)). The [luatex manual](https://tug.org/svn/texlive/trunk/Master/texmf-dist/doc/luatex/base/luatex.pdf?revision=65866&view=co) is austere in its examples and explanations for most things, and I see essentially nothing about `\deferred` other than a mention as a *prefix* on page 47 (not sure if this is the same thing) and its appearance in the big list of primitives on page 207.
What does `\deferred` do? My naïve guess based on the git changes is that it's some counterpart to [`\immediate`](https://tex.stackexchange.com/q/20444/208544), possibly related to the new "late special" feature. Beyond what it does, does anyone have an example document in which the new primitive is used to do something not previously possible?
**P.S.** If your texlive is not new enough, you can see that it is actually a proper "command" with [this example](https://texlive.net/run?%25%20!TEX%20lualatex%0A%5Cdocumentclass%7Barticle%7D%0A%5Cbegin%7Bdocument%7D%0Aabc%20%5Cdeferred%7B%7D%0A%5Cend%7Bdocument%7D) on texlive.net.
| https://tex.stackexchange.com/users/208544 | What does the new luatex primitive \deferred do? | true | Exactly as muzimuzhi said: `\deferred` is a LuaTeX alternative to the `shipout` keyword. That is, both should do the exact same thing.
The `shipout` keyword was implemented in pdfTeX (and ~~copy-pasted~~ ported to XeTeX, e(u)-pTeX, and Aleph) because we needed a “late expansion” for `\special`. When Hans implemented it for LuaTeX, he probably thought a `\deferred` prefix is better because it's symmetric to `\immediate`. muzimuzhi already answered your question spot-on, so here's an explanation of what `\deferred` or the `shipout` keyword are for:
When you use `\special`, it fully expands the argument (pretty much like `\expanded`), then adds the expanded token list as a whatsit node to the output list. That node is then written as-is to the output `.pdf` or whatever format the engine produces.
The problem with that, is that when TeX is reading your `\special`, it doesn't know it what page that `\special` will be placed, so using things like `\thepage` will sometimes give the wrong information.
In the example (pdfTeX) document below, we are typesetting one long paragraph across three pages: at the time TeX reads the `\special` (when it is building the horizontal list for the paragraph), it is still processing the first paragraph in page 1 (first it builds the list of nodes, then it breaks the list into lines, then those lines across pages), so `\count0` (the page number) is 1, so it colours the text red.
If you switch to `\special shipout` it will hold the token list unexpanded until the page shipout (when everything is in its final position in the page), and only then it expands the token list, and evaluates the value of `\count0`. At this point, TeX already knows it's on page , so it colours blue.
```

All of this was already possible without these extensions, but it required you to run TeX multiple times to make TeX write your `\special` on the page, then find out where it ended up, and then use that information (stored in a temporary file) to do the right choice later. This extension lets you do all in one go, without extra data structures and build steps.

https://tex.stackexchange.com/questions/565010 | 1 | I'm using a `Glyph` tip from `tikz-cd` to get arrows like `\looparrowright` and friends.
However I would like to change the color. `latex` compiles the following MWE correctly, but `xelatex` leaves the loop black while coloring the rest of the arrow red.
```
\documentclass{standalone}
\usepackage{amsmath,amssymb}
\usepackage{tikz-cd}
\tikzset{
loop/.tip={Glyph[glyph math command=looparrowleft, swap]},
loop'/.tip={Glyph[glyph math command=looparrowleft]}
}
\begin{document}
\begin{tikzcd}
A \ar[r, loop->, red] & B \\
% This arrow is red, but the loop part of the tip is black.
\end{tikzcd}
\end{document}
```
| https://tex.stackexchange.com/users/185446 | Set the color of a tikz-cd Glyph arrow tip with xelatex | false | This seems to be related to the [same old XeLaTeX problems](https://github.com/pgf-tikz/pgf/issues/750) PGF/TikZ has when it comes to colors.
As an alternative to fixing `\pgftext` or somehow sneaking another color `\color` command inside, here's an arrow tip `Loop` that draws something similar. This uses only arc (with radius `inset`) in a loop with diameter `length` (± linewidth fuzziness). The `\looparrowleft` glyph you use seem to use a Bézier curve instead of an arc with a fixed radius. If that is expected, a few adjustments and fiddling around with good controls values are needed.
You can fill the loop part, you can `swap` it and `reversed` with in my opinion pretty good results.

https://tex.stackexchange.com/questions/669436 | 1 | Does anybody know how to plot a non-central t distribution using `pst-fun` from pstricks or tikz. For the central t, `pst-fun` has the function `psTDist`, but I can find a way to add a $\delta$ ncp to it.
For the central t is quite straigt foward:
```
\documentclass[border=5mm]{standalone}
\usepackage{pst-plot,pst-func}
\begin{document}
\psset{xunit=1cm,yunit=7.5cm}
\begin{pspicture}(-5.25,-0.05)(5.25,0.5)
% Valor de corte z
\newcommand\z{1.3}
%Dist
\psTDist[nue=9,yunit=1]{\z}{4}
\end{pspicture}
\end{document}
```
I wonder if I need just to generate the non-central t-distribution and plot the points overlapping.
Thansk!

(red lines indicate page layout)
As you can see, your table is wider than available space for text in page. To correct this, you have two options:
* increase `\textwidth` by use of `geometry` package
* enables automatic split cells contents in all cell in table. For this you should define `m` column type or use `tabularx` table, where redefine `X` columns to
```
\renewcommand\tabularxcolumn[1]{m{#1}}
```
or use `tabularray`package.

Actually, my main purpose is to expand the table to the column width without changing the font size.

| https://tex.stackexchange.com/users/5645 | Draw a unicorn in TikZ | false | Let's apply some `Artistic Intelligence` on my [line-stroke-drawing](https://i.stack.imgur.com/my8iX.png). To give it a `cubistic touch` let's introduce some colored areas by:
1. just filling some strokes
2. introducing new colored shapes
Though it builds on the previous approach the concept is slightly different, using other properties `tikz` provide in two different ways.
Are the results pleasing? When to stop, where to continue? Humans decide, humans know, ...

| https://tex.stackexchange.com/users/5645 | Draw a unicorn in TikZ | false | Let's criticise my previous [drawing with line strokes](https://tex.stackexchange.com/a/681437/245790).
From research and knowledge:
* unicorns come with color
* rainbow-like colors are an important ingredient
* unicorns are fiction, held dearly by many
How to reflect these issues? One way to do it is using `tikz` features to process pathes. Let's apply `Artistic Intelligence` again.

https://tex.stackexchange.com/questions/681215 | 3 | In my document, I have a table, I want to use `\setlength{\tabcolsep}{18pt}` but since there is one more table, this also affects the other, which I don't want to change. Therefore I thought of creating another ".tex" file which has only 1 table and then including it in the main file, but this didn't work. What can I do? Actually, my main purpose is to expand the table to the column width without changing the font size.
```
\setlength{\tabcolsep}{18pt}

https://tex.stackexchange.com/questions/681512 | 4 | I would like to hold some text in a global variable, which i'm using as the content of a `tabular`. I'm using `expl3`, and `tikz` to place the `tabular`. The problem is that in an expl3 environment tikz is not working as expected.
Here after reading solutions to similar problems i got my code working.
```
\documentclass{beamer}
\mode<presentation>
\usepackage{tikz,tabularray}
\ExplSyntaxOn
\tl_new:N \tl_tmpa
\ExplSyntaxOff
\ExplSyntaxOn
\NewDocumentCommand{\mycontent} { m }
{
\tl_clear:N \tl_tmpa
\tl_put_right:Nn \tl_tmpa {
\begin{tblr}{|l|}
\hline
#1
\hline
\end{tblr}
}
\let\mytikznode\tl_tmpa
}
\ExplSyntaxOff
\NewDocumentCommand{\myframe} {}
{
\begin{frame}
\begin{tikzpicture}[remember picture,overlay]
\node at (current page.north)
[shift={(0,-4)}, anchor=north]{
\mytikznode
};
\end{tikzpicture}
\end{frame}
}
\begin{document}
\mycontent{ a a a \\
b b b \\}
\myframe
\end{document}
```
If I move the two statements `\begin{tblr}{|l|}` and `\end{tblr}` in `\myframe` and leave
```
\hline
#1
\hline
```
in `\mycontent` and not touching anything else, the build fails. Also without doing `\let\mytikznode\tl_tmpa` and using `\tl_tmpa` instead of `\mytikznode` in `\myframe` the build fails. I still don't see where is coming from the problem. I'm posting it to get some clarity and if possible get the code more concise.
| https://tex.stackexchange.com/users/145290 | expl3 and tikzpicture | true | The deeper the nesting, the more cautious you need to be with expansion. In this case, you need to expand the contents of the `tblr` environment before it is being parsed. The `tabularray` package provides an `expand` option exactly for such cases (see section 3.2.3 Expand Macros First in the [`tabularray` manual](http://mirrors.ctan.org/macros/latex/contrib/tabularray/tabularray.pdf)).
More concretely, in your case you would need to replace `\begin{tblr}{|l|}` by `\begin{tblr}[expand=\mytikznode]{|l|}`:
```
\documentclass{beamer}
\mode<presentation>
\usepackage{tikz, tabularray}
\ExplSyntaxOn
\tl_new:N \tl_tmpa
\ExplSyntaxOff
\ExplSyntaxOn
\NewDocumentCommand{\mycontent} { m } {
\tl_clear:N \tl_tmpa
\tl_put_right:Nn \tl_tmpa {
\hline
#1
\hline
}
\let\mytikznode\tl_tmpa
}
\ExplSyntaxOff
\NewDocumentCommand{\myframe} {} {
\begin{frame}
\begin{tikzpicture}[remember picture,overlay]
\node at (current page.north)
[shift={(0,-4)}, anchor=north]{
\begin{tblr}[expand=\mytikznode]{|l|}
\mytikznode
\end{tblr}
};
\end{tikzpicture}
\end{frame}
}
\begin{document}
\mycontent{ a a a \\
b b b \\ }
\myframe
\end{document}
```
---
Actually, you can simply stay in expl3 mode. There is no need to `\let\mytikznode\tl_tmpa` then (you only need to take care about spaces in Ti*k*Z options). Also, better adhere to the established naming conventions of the expl3 syntax:
```
\documentclass{beamer}
\mode<presentation>
\usepackage{tikz, tabularray}
\ExplSyntaxOn
\tl_new:N \l_userx_temp_tl
\NewDocumentCommand{\mycontent} { m } {
\tl_clear:N \l_userx_temp_tl
\tl_put_right:Nn \l_userx_temp_tl {
\hline
#1
\hline
}
}
\NewDocumentCommand{\myframe} {} {
\begin{frame}
\begin{tikzpicture}[remember~picture,overlay]
\node at (current~page.north)
[shift={(0,-4)}, anchor=north]{
\begin{tblr}[expand=\l_userx_temp_tl]{|l|}
\l_userx_temp_tl
\end{tblr}
};
\end{tikzpicture}
\end{frame}
}
\ExplSyntaxOff
\begin{document}
\mycontent{ a a a \\
b b b \\ }
\myframe
\end{document}

=====
This question regards the following workflow: markdown file (input) -> pandoc -> PDF (output)
Pandoc version:
```
$ pandoc --version
pandoc 2.9.2.1
Compiled with pandoc-types 1.20, texmath 0.12.0.2, skylighting 0.8.5
```
Problem description
===================
Expected behavior: Every chapter in a PDF book gets a chapter number. At the start of the first chapter I get a "Chapter 1" text before the chapter's title.
Behavior I get: No chapter numbering.
Minimum Working Example (MWE)
=============================
metadata.yaml
-------------
```
---
papersize: a4
documentclass: book
top-level-division: chapter
number-sections: true
---
```
book.md
-------
```
% Book Title
Book subtitle

% April 1, 2023
# Introduction
This should have been Chapter 1.
Lorem Ipsum. Hello world!
# Chapter problem
This is chapter 2. Why is there no Chapter Numbering?
## Section
There is no section numbering either.
```
Command to replicate
--------------------
I use the following command to generate the PDF:
```
pandoc --metadata-file=metadata.yaml book.md -o book.pdf
```
Question
========
What am I doing wrong? I assumed that pandoc would automatically number each chapter, but it apparently does not. Is there a way to force pandoc to number each chapter?
| https://tex.stackexchange.com/users/294170 | Missing chapter numbering in pandoc | true | You should pass the `--number-sections` option to `pandoc` like this:
```
pandoc --metadata-file=temp.yaml --number-sections temp.md -o temp.pdf
```
To experiment replace the target `temp.pdf` by `temp.tex` and use `--standalone` then inspect the tex file for `secnumdepth`.
CAVEAT: I am with pandoc `2.18`.
EDIT: actually here is how to do it with yaml file:
```
---
papersize: a4
documentclass: book
top-level-division: chapter
numbersections: true
---
```
Watch out how the variable is named and used.
So basically, you only had a typo of using `number-sections` in place of `numbersections`... the latter is the yaml variable the former is for the `-number-sections` command line toggle.

| https://tex.stackexchange.com/users/56838 | Error compiling code due to text in the title of a chapter that is encoded in math mode | true | From some Sherlock Holmes level enquiry in the [distant path](https://fr.comp.text.tex.narkive.com/tfyLhMeX/metric-tfm-file-not-found-comment-resoudre-ce-probleme) it looks as if in the past there was a guilty file `ubbold.fd` in `.../texmf-dist/tex/latex/jknapltx/` where I am using some kind of TeXLive base TeX installation. From what I decipher there, this might explain `bbold25` showing in error message.
On my TeXLive 2023 I don't have one in this directory. I have a `Ubbold.fd` in `texmf-dist/tex/latex/bbold`. And this one should not cause problem. The `bbold` package provides a `\mathbb` command.
I advise you add `\listfiles` to your preamble and report what is shown in log after `*File List*`. (mainly to know what kind of distribution you are using, is it up-to-date?)
Perhaps you have some such old `ubbold.fd` in some `texmf-local`? or in a `texmf` in your `$HOME`?
It may be that adding a file named `ubbold.fd` like this
```
\DeclareFontFamily{U}{bbold}{}
\DeclareFontShape{U}{bbold}{m}{n}
{ <5> <6> <7> <8> <9> gen * bbold
<10> <10.95> bbold10
<12> <14.4> bbold12
<17.28> <20.74> <24.88> bbold17
}{}
\endinput
```
in the directory of the project could fix this.
Perhaps. Maybe to be sure also save it as `Ubbold.fd`. I am on a Mac, which is not case-sensitive. Perhaps LaTeX NFSS normalizes anyhow by making things lowercased but I have not checked.

work fine when the numbers are minor that 15999, but when multiply 15999x15999 fail or when the numbers (any) mayor that 15999.
How can I do to use great number? In the deep, not more great only 101325. The problem I think that not is `siunitx` package, because I use bigger numbers without problem.
Thanks a lot!

| https://tex.stackexchange.com/users/216257 | Calculator package with great number? | false | First: the `\SI` macro in `siunitx` is obsolete and should be replaced with `\qty`.
Second, for such a use case you should probably use the LuaLaTeX compiler, so that you can make the computations in Lua and have them printed in LaTeX.
```
\documentclass{article}
\usepackage{luacode}
\usepackage{siunitx}
\directlua{
a = 15999
b = 15999
c = 1e8
d = 3.4e12
}
\begin{document}
First ratio : \qty{\directlua{tex.print(a/b)}}{m}
Second ratio : \qty{\directlua{tex.print(c/d)}}{Hz}
\end{document}
```
As you can see, everything you type in the `\directlua` macro is Lua code. Then, inside the Lua code, the `tex.print` function sends the value of its argument to LaTeX.
Also, if you have several `\directlua` macros, they are treated as part of the same block of code, so you can reuse variables from one to the other.
If you want to format the numbers, you can do it in Lua using the usual string-formatting functions before sending them back to LaTeX.

What works best for now, I figured, is to simply use the git command line and not fiddle with the LyX GUI.

Checking the log is tedious and ultimately unrewarding, because not even in there can I find the actual line which contained the undefined control sequence.
**Can this awful behavior be helped in any way?**
| https://tex.stackexchange.com/users/2199 | Unhelpful, misleading errors in amsmath environments | false | The reason of the error, as explained in other answers, is that `align` is not a "real" environment, rather

Of course, this implementation output quality is nowhere comparable to, but it preserves line number in error messages and also synctex information. For draft compilations/debugging, I think it may be useful.
Note: this is not very well-tested. It may create other errors that the original environment does not.
For a comparison of output quality (it's **supposed to be bad**! Do not use in final document):
Left is normal output, right is output with the hack. (you can also notice tag numbers are missing)
---
Given the complicated things that amsmath do with its content, I think doing multiple passes for measurement is **required**.
Detail of what amsmath do:
However I can think of 2 workarounds:
* use the technique I described in [How can I capture and rescan TeX source code while preserving synctex data?](https://tex.stackexchange.com/q/631887/250119) to preserve line number of error message/synctex information.
* use multiple compilation passes and aux file to store information etc.
---
Using that idea, at the moment *another* hack is possible with my `cprotectinside` package:
```
%! TEX program = lualatex
\documentclass{article}
\usepackage{amsmath}
\usepackage{cprotectinside}
\cprotectinsideEnableSyncInner
\begin{document}
\errorcontextlines=10
\cprotectinside{|}{
\begin{align}
|%
a_{11}& =b_{11}&
a_{12}& =b_{12}\\
a_{21}& =b_{21}&
a_{22}& =b_{22}+c_{22}
|
\end{align}
}
\end{document}
```
(it also preserves synctex if lualatex is used, and error messages at least point to the correct *lines*, although filename may be a bit confusing. Note that it requires a new version on GitHub that is not published on CTAN)

| https://tex.stackexchange.com/users/294191 | Formatting Help Needed for Math Problem Set in LaTeX | false | I think user Teepeemm gave you the answer already. I could use an itemize environment at the end of your file to get a better math display, or vertically align your matrices in subsection 3, and so on. But if you REALLY WANT to format things manually, you could look at the commands provided by TeX back in the day. For example, `\!` and `\;` gives you predefined white space:
`x-2\!=\!\frac{y+3}{2}\;=\;\frac{z-1}{4}`
`\mkern` gives you a blank space of a given width:
```
2\mkern 30mu y-z=1
```
`\scriptstyle` changes the default font style
```
$${\scriptstyle
A=\left[\begin{array}{llll}
1 & 5 & 4 & 4 \\
3 & 4 & 1 & 6 \\
0 & 0 & 1 & 5
\end{array}\right], \quad B=\left[\begin{array}{ccc}
5 & -5 & 0 \\
0 & 1 & 0
\end{array}\right], \quad C=\left[\begin{array}{lll}
1 & 0 & 3 \\
0 & 1 & 2
\end{array}\right], \quad D=\left[\begin{array}{lll}
1 & 3 & 2 \\
3 & 9 & 5
\end{array}\right]}
$$
```
And many more, so you can check them out in your favourite texbook if you're interested. But then again, that comes with a price that LaTeX might not like that too much.

https://tex.stackexchange.com/questions/681589 | 2 | I'm trying to issue TeX warnings from within `\directlua` with accurate line numbers (pointing to the offending line in the `.tex` document).
When I compile the MWE below with lualatex, `\TestTex` issues a warning that correctly points to line 40. However, `\TestLua` and `\TestLuaIndirect` both issue warnings pointomg to line 1.
Any help would be much appreciated. Thank you!

| https://tex.stackexchange.com/users/170958 | Throwing warnings inside \directlua | true | Basicaislly `sprint` creates a new "file-like layer" in the input stack (imagine that a `\input{tmpfile}` is executed, and the warning itself is on line 1 of the temporary file). You want to unroll it "as if it's executed from a macro".
Speaking of which, `\ExplSyntaxOn` inside any `{...}` is almost-always wrong: [macros - Why doesn't \makeatletter work inside \newcommand? - TeX - LaTeX Stack Exchange](https://tex.stackexchange.com/questions/201348/why-doesnt-makeatletter-work-inside-newcommand)
One possible workaround follows, use `\futurelet` to force unroll the input stack, similar to the case in my question/answer [luatex - How can I make macros called from tex.print tail-recursive? - TeX - LaTeX Stack Exchange](https://tex.stackexchange.com/questions/640922/how-can-i-make-macros-called-from-tex-print-tail-recursive). Note that the `sprint` must be the **last** one in the `\directlua` block for this to work.
```
\documentclass{article}
\ExplSyntaxOn
\msg_new:nnn { test } { test-warning } { #1 ~ \msg_line_context: }
\NewDocumentCommand { \TestTex } { }
{
\msg_warning:nnn { test } { test-warning } { tex ~ warning }

Of course the disadvantage is that the catcode is fixed.
An alternative is to print a token directly:
```
\documentclass{article}
\ExplSyntaxOn
\msg_new:nnn { test } { test-warning } { #1 ~ \msg_line_context: }
\NewDocumentCommand { \TestTex } { }
{
\msg_warning:nnn { test } { test-warning } { tex ~ warning }
}
\NewDocumentCommand { \TestLuaIndirect } { }
{
\directlua
{
token.put_next(token.create('TestTex'))
}
}
\ExplSyntaxOff
\begin{document}
Test.
\TestTex
\TestLuaIndirect
\end{document}
```
Refer to [Can the Lua part of LuaTeX know about tokens?](https://tex.stackexchange.com/questions/45293/can-the-lua-part-of-luatex-know-about-tokens?noredirect=1&lq=1) and `texdoc luatex` for some documentation.

https://tex.stackexchange.com/questions/84983 | 8 | With the simple `equation` environment;
```
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
a \foo b
\end{equation}
\end{document}
```
you can see a helpful error message, which editors like Kile understands;
```
! Undefined control sequence.
l.5 a \foo
b
```
Making it report `5: Undefined control sequence a \foo`
But if you do the same in an amsmath environment, such as the popular `align`
```
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
a \foo b
\end{align}
\end{document}
```
you get the unhelpful error (and it comes up twice);
```
! Undefined control sequence.
<argument> a \foo
b
l.6 \end{align}
```
which makes Kile report; `6: Undefined control sequence \end{align}`.
Checking the log is tedious and ultimately unrewarding, because not even in there can I find the actual line which contained the undefined control sequence.
**Can this awful behavior be helped in any way?**
| https://tex.stackexchange.com/users/2199 | Unhelpful, misleading errors in amsmath environments | false | TeX is unable to report more information about undefined control sequence. Suppose the following example:
```
\def\process#1{{\preprocess #1}}
\def\preprocess{\def\foo{Hello}}
\process{
There is
a text
with \foo.
More
lines.
}
\let\preprocess=\relax
\process{
There is
a text
with \foo.
More
lines.
}
\bye
```
The first usage of `\process` runs without errors, the second usage will cause the error:
```
! Undefined control sequence.
<argument> There is a text with \foo
. More lines.
\process #1->{\preprocess #1
}
l.20 }
```
You can see, that TeX cannot check, if all control sequences in scanned argument is defined during scanning it and before the argument is used. The meaning of control sequences can be changed before the usage of the argument somewhere in the depths of macros.
Of course, the error message "undefined control sequence" could contain the problematic control sequence printed itself, but such a message format goes against other error message formats reported by TeX. TeX adheres to the principle: All error messages keeps uniform style.
Everything else is a problem of log scanners if they are used.

https://tex.stackexchange.com/questions/681095 | 1 | I am using the compiled version of `Kile` since a while (version 2.9.94). As my projects I am working on are large and take a longer time to compile, I am using `subfile{}` to speed up the compilation (which works quite nicely). However, in the `structure` tree of Kile, these files are not displayed and I have to manually open the files into Kile in order to edit them. Is there any possible way to get the files which are included via the `subfile` keyword are shown up in the `structure` tree as well? I read something that I can activate the inclusion of such files in `Kile -> Settings -> Build` somewhere but I could not find anything there.
Note: When I change the `subfile` to `include` it directly gets visible in the `structure` tree of Kile.
| https://tex.stackexchange.com/users/116084 | Allow Kile to show subfiles in the structure tree | true | It seems that, due to the fact that `subfile` mimics separate latex documents itself, that Kile cannot recognize them. However, I found an easy workaround by simply creating a `Project` in Kile and add all the files manually. That's good enough and resolves my issue.

* combine two [previous](https://tex.stackexchange.com/a/681500/245790) drawings I [posted](https://tex.stackexchange.com/a/681437/245790) here as `tikz pics`
* shift the two `\pic`s against each other via the "constant" `\newcommand\shft[0]{1}`
Relevant code section:
```
\tikz{
\pic at (-\shft,0) {beauty};
\pic [xscale=-1] at (+\shft,0) {uni};
}
```
For `shft=1`, this is the result:
But it's also fun to see what happens for 0, 2, 2.5, 3, 3.5, 4 and 5. Wrt. `AI` they can be generated easily, but not all will be appreciated as nice, esthtic or beautiful. Some may appear disturbing, or like taken from a test from psychology. The last one even qualifies for "telling a story by one picture". Or in techno-speak: `shft` introduces a lot of `noise` for us humans.
