https://tex.stackexchange.com/questions/687420 | 0 | I am using a latex template to complete my thesis. **I would like to insert appendix in my thesis, like "Appendix A, Appendix B". I would very appreciate if someone tell me how to insert appendices.**
I tried several methods to insert appendix but they don't work as disired. When using the following command
```
\appendix
\chapter{test}
```
in the "appendices.tex" file, it can not be compiled and output the wrong message below.

I tried the command `\section{test}`, but it also can not be compiled. I also tried to use the package `\usepackage[title, titletoc]{appendix}`. In this case, the appendix can be generated. However, it can not satisfy the format requirement of the thesis, so I guess it would be better to use the command given by the template itself.

https://tex.stackexchange.com/questions/8791 | 247 | Usually I don't mind about LaTeX's compilation speed, because a paper of less than 20 pages is compiled rather fast. However, I am working on a large document - A report with more than 80 pages. Compilation times are starting to slow me down. I saw the couple of answers here on this topic, but most of my graphics are external and I don't use Tikz. As a matter of fact, I'm not sure what's slowing the compilation down, other than the amount of text and required layout.
1. What's your best speeding-tex-up trick, other than externalizing graphics and pre-compiling the preamble?
2. How can I know what's slowing TeX down?
| https://tex.stackexchange.com/users/1527 | Speeding up LaTeX compilation | false | It is slow and will get even slower (which is an empirically well-established issue for all software development and not only for LaTeX). As usual, the ultimately best way may be to improve the architecture and the source code of (La)TeX and its packages and clean up the messy code in the process. That is, rewrite everything from scratch (which seems to be a project attainable only for folks having both finances and decades to spend on typesetting for the rest of their lifetime), starting with the goals and the documentation (i.e, how things should be). Outdated interfaces might be left out in the process, which, ultimately, would lead to a different and incompatible typesetting system.
The way out is to become a serious typesetting developer or to learn to live with what you get, in particular, slow compilation.
Not being a serious LaTeX developer, I have two versions of any of my large books: a draft version and a clean version. A book has two main files (say, draft.tex and clean.tex, where draft.tex defines my own macro `\draft` and inputs clean.tex). The program `latex` compiles the draft version quickly into DVI (sometimes followed by dvips), and `lualatex`/`xelatex` compiles the clean version slowly into PDF. Moreover, the document source is split into many files so that I can edit them while both `latex` and `lualatex`/`xelatex` run in the background. The only disadvantage is that your document source will likely have to contain several occurrences of `\ifdefined\draft…\else…\fi` (most often in the preamble and seldom in the main text), e.g., when loading different fonts and hyperlink-related packages.

Normally just follow the instruction suffices. However if something goes wrong, knowing what is going on under the hood helps you to diagnose the issue.
How to use `mylatexformat`? [basic instruction]
-----------------------------------------------
Say, you have a normal LaTeX document `a.tex`:
```
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align*}
1+2 &= 3
\end{align*}
\end{document}
```
Assume `a.tex` does not contain space, or special character such as `%#{}~`.
First you execute `pdftex -ini -jobname=b "&pdflatex" mylatexformat.ltx a.tex`. This will generate `b.fmt`. (the file name is specified by `-jobname`, if not specified default to `mylatexformat.fmt`)
Then you execute `pdftex "&b" a.tex`. This will generate `a.pdf` as usual.
### Remark on reading `mylatexformat` package documentation
* `-ini` and `-initialize` is the same thing.
* Its instruction on writing `"""abc.tex"""` on the command-line is for Windows only, on Linux/Bash you need
`"\"abc.tex\""`. (basically pass the file name wrapped in *one layer of double quote* to TeX)
* If the first line of `a.tex` is `%&b`, then the 2nd command you don't need to explicitly specify `"&b"` on the command-line,
anything such as `pdftex a.tex` or `pdflatex a.tex` will suffice. Nevertheless [**this method does not work with LuaTeX**](https://tex.stackexchange.com/questions/622002/lualatex-not-parsing-first-line-format-in-texlive).
How to use `mylatexformat`? [advanced instruction]
--------------------------------------------------
### Use XeLaTeX/LuaLaTeX instead of PDFLaTeX
Replace `pdftex` with `xetex` or `luahbtex` respectively. Furthermore you need to replace the preloaded format name `&pdflatex` with `&xelatex` or `&lualatex`.
You can tell that `xelatex` and `lualatex` executable are just `xetex` and `luahbtex` with `xelatex.fmt` and `lualatex.fmt` formats preloaded by seeing what it prints out at the beginning.
Furthermore note that first-line `%&b` (as written in package documentation) will not work in LuaTeX.
For example:
```
% a.tex
\documentclass{article}
\usepackage{amsmath}
\csname endofdump\endcsname
\usepackage{unicode-math} % incompatible with precompiled preamble, see below
\begin{document}
\begin{align*}
1+2 &= 3
\end{align*}
\end{document}
```
Then in the shell:
```
luahbtex -ini -jobname=b "&lualatex" mylatexformat.ltx a.tex
luahbtex "&b" a.tex
```
This only speed up by a small amount, in my experience for an almost-empty document it is 0.6s → 0.4s.
### Do not precompile the whole preamble
If some part of the preamble either:
* changes frequently (so you don't want to include into the format), or
* relies on `\jobname` (for example `\usepackage{currfile}`, or [`pythontex`](https://tex.stackexchange.com/q/279845/250119)), or
* is incompatible with TeX format, such as `\usepackage{unicode-math}` or `\usepackage{fontspec}`, (see "two other classes of things that can not be dumped." in [David Carlisle's answer](https://tex.stackexchange.com/a/83486/250119))
+ For some reason for LuaLaTeX even `tikz` is incompatible.
+ I don't see any easy way to easily tell what package is compatible and what is not, you will just have to try including/excluding it.
then you must exclude it from the preamble.
To do that use `\csname endofdump\endcsname` (the spelling must be exactly like that) -- see `mylatexformat` documentation for
more details. Using this instead of `\endofdump` makes sure the file is compilable (the line is simply ignored) if `mylatexformat`/precompiled preamble is not used (i.e. the file is compiled the normal way).
What is precompiled preamble/format?
------------------------------------
Basically, it is just using TeX's INITeX feature to speed up processing of a fixed preamble part.
TeX supports generating *formats* that can be loaded later.
Refer to TeX by Topic chapter 33 "TeX and the Outside World" for some details.
(Reading TeXbook might be a bit confusing, just keep in mind that typing anything on the command-line is equivalent to typing it on the `**` first line in the TeX prompt.)
In short:
>
> A format file (usually with extension .fmt) is a compact dump of TEX’s internal structures. Loading a format file takes a considerably shorter time than would be needed for loading the font information and the macros that constitute the format.
>
>
>
So you can "define some commands, dump the internal state to a file", then when you "load" that file it's "as if" the commands have been defined similar to at the time how the format was dumped.
For an example:
```
% preamble.tex
\documentclass{article}
\usepackage{amsmath}
\dump
% a.tex
\begin{document}
\begin{align*}
1+2 &= 3
\end{align*}
\end{document}
```
In the shell execute `pdftex -ini "&pdflatex" preamble.tex`, this will
* start with the existing `pdflatex.fmt` format (might be at `/var/lib/texmf/web2c/pdftex/pdflatex.fmt` depends on operating system etc.)
* execute from file `preamble.tex`
* when `\dump` is executed generates file `preamble.fmt`.
The `-ini` is needed to enable the `\dump` command.
After that if `pdftex "&preamble" a.tex` is executed (this means "execute `a.tex` with preloaded format `preamble.fmt`") it will generate `a.pdf` with the correct content. (For an analogue, `pdftex "&pdflatex" a.tex` is equivalent to `pdflatex a.tex`)
What does `mylatexformat` package do?
-------------------------------------
As you can see above, it's rather inconvenient to have to split the file into separate `preamble.tex`.
So `mylatexformat` allow you to put them in the same file and it will automatically detect the split between the preamble and the main file.
How does `mylatexformat` work (regarding the command-line)?
-----------------------------------------------------------
There's 2 steps -- generating the format, and using the format.
In the first step, apart from `-jobname`, the command-line is:
`pdftex -ini "&pdflatex" mylatexformat.ltx a.tex`
Because of historical reasons, it's made such that (almost) anything put on the command-line is equivalent to typing it to the first
line of `**` prompt. So you can also run `pdftex -ini` then on `**` prompt type in `&pdflatex mylatexformat.ltx a.tex`, both are equivalent.
Most of this is familiar. Recall that `pdftex -ini "&pdflatex" mylatexformat.ltx` will start with preloaded format `pdflatex.fmt`
and execute content of file `mylatexformat.ltx`. However, the additional `a.tex` will be **put on the input stream**.
At the very end of `mylatexformat.ltx`, after redefining `\begin` etc. there's
```
%% Trick lookahead to allow mylatex.ltx and the document filename to be
%% given on the same command line. (initex &latex mylatex.ltx {abc.tex})
\expandafter\input\endinput%
\endinput
```
so effectively (some TeX programming knowledge is needed) `\input a.tex` is executed. See also [wipet's answer](https://tex.stackexchange.com/a/672107/250119).
That's why it's useful to pass another pair of quotes in the command-line.
For other details of the implementation (how it separates the preamble from the document) read the documentation.

The mark region 'page' contains some infinite negative glue allowing it to

It is possible that you will still get errors caused by other files. It is best to try to update your TeX distribution to TeX Live 2023.
With TeX Live 2023, I get another error, which can be fixed using this configuration file, `config.cfg`:
```
\Preamble{xhtml}
\catcode`\:=11
\makeatletter
\def\chessboard:alt{\ifdefined\o:xskakget:\ifcsname Xskak.\xskak@val@gameid.\xskak@val@movenr.\xskak@val@player.nextfen\endcsname\o:xskakget:{nextfen}\fi\fi}
\makeatother
\catcode`\:=12
\begin{document}
\EndPreamble
```
You can compile your file from the command line, using:
```
$ make4ht -c config.cfg filename.tex
```
With this change, the file should compile without errors:

https://tex.stackexchange.com/questions/687382 | 6 | In microbiology, the first time a species name is used, it should be written the genus and species in full (Escherichia coli). For all other occurences, the genus should be abbreviated (E. coli).
I managed to do this by using the glossaries package.
Nevertheless, when another species is cited, for example Escherichia fergusonii, it should be directly abbreviated E. fergusonii if E. coli has already been cited to avoid repetitions.
What I used so far to automatically abbreviate the genus names:

If the genus has already been used, just the first letter is used (followed by a period and `\nobreakspace`), otherwise the full genus name is used. Then the species name, everything in italics.
I also provide `\species*` that prints the full genus name (and marks it as used anyway).

https://tex.stackexchange.com/questions/687461 | 2 | I am using LuaLaTeX and unicode-math in my documents. I input most of the simple symbols (sum, products, greek letters, quantification, etc.) directly in unicode (using agda-mode for emacs). When I input the unicode character "SCRIPT CAPITAL L" (U+2112), I get in the pdf the equivalent of a `\mathscr L`. How can I tell the package unicode-math that I would like to have a `\mathcal L` instead whenever it encounters a unicode character U+2112?
Ideally, I would like to just pass an option to the package so that all "SCRIPT ..." uses `\mathcal ...` instead of `\mathscr ...`
**EDIT.** To clarify, here is a MWE:
```
\documentclass{minimal}

Mathcal input: $\mathcal L$
Mathscr input: $\mathscr L$
\end{document}
```

https://tex.stackexchange.com/questions/205057 | 2 | I tried to replace the temporary labels TMP1, TMP2 and TMP3 in an .eps file made with ChemDraw v18 on Mac OSX Mojave using the `chemnum` package, so to get an automatic numbering of the compounds, but this did not work for me.
I tried different fonts for the label in the .eps file, or other options for `auto-pst-pdf` with no result.

| https://tex.stackexchange.com/users/63878 | No replacement of temporary labels by chemnum in a ChemDraw eps on Mac | false | The Problem is (independently of the Chemdraw Version: I used v16.0.0 and v22.0.0) because Chemdraw on MacOS has a bug when creating an .eps File so the string doesn't appear on a text Editor (a.k.a.: Ghostscript). The solution I found was:
1. Save the cropped File as a PDF (uncheck the Box: 'Break into pages'[v.22.0.0]. I didn't Found that Option on v.16.0 ).
2. Then convert the File.pdf to File.eps with a converter.
3. (optional) Open the .eps File with a text Editor and you will find the Script with the temporary marker (example.: TMP1).

https://tex.stackexchange.com/questions/686792 | 6 | The [documentation of `xparse`](//texdoc.net/pkg/xparse) states (emphasis mine):
>
> *`r`* Given as `r⟨token1⟩⟨token2⟩`, this denotes a “required” delimited argument, where the delimiters are `⟨token1⟩` and `⟨token2⟩`. **If the opening delimiter `⟨token1⟩` is

>
> *`R`* Given as `R⟨token1⟩⟨token2⟩{⟨default⟩}`, this is a “required” delimited argument as for `r`, **but it has a user-definable recovery `⟨default⟩` instead of `-NoValue-`**.

However in both cases, an error is produced if the parameter is not specified. And I can't see any difference in the error message between `r` and `R`.
* How exactly does this *default marker *`-NoValue-`** intervene?
* And what is the purpose of this additional `{⟨default⟩}`? Any use case?
Is it to avoid additional errors where the corresponding parameter `#N` is used? Or (for `R`) somehow document the parameter with that default value? Any notable difference between `r` and `R` in the end?
Note: I already know about the related optional types `d`/`D`.

I'd like to add another interesting usecase I just found for a required argument default marker/value.
Let's assume I want to split one argument and be able to pass 1, 2 or 3 values :
```
\test{1, 2, 3}
\test{1, 2}
\test{1}
```
Using:
```
\NewDocumentCommand{\test}{ >{ \SplitArgument{2}{,} } m }{\impl #1}
```
`\impl` will respectivelly receive
```
\impl{1}{2}{3}
\impl{1}{2}{-NoValue-}
\impl{1}{-NoValue-}{-NoValue-}
```
optional arguments will fail here as the arguments are passed no matter what, with `{}`.
```
\NewDocumentCommand\impl{m m m}{%
\#1 = #1,
\#2 = \IfValueTF{#2}{#2}{default},
\#3 = \IfValueTF{#3}{#3}{default}
}
```
outputs:
```
#1 = 1, #2 = 2, #3 = 3
#1 = 1, #2 = 2, #3 = default
#1 = 1, #2 = default, #3 = default

https://tex.stackexchange.com/questions/534331 | 1 | I'm new to latex but would really like to use it to write my dissertation (chemistry, obviously). Labwork is nearly done, but that seems to be the lower hurdle right now :D
Right now, I'm trying to use the chemnum package to get nice labels for all compounds. Theoretically, it should replace "TMP"-markers (which are given in an external eps file created by the chemdraw software) with automated numberings. However, I fail to even get the example file running using TeXstudio:
<https://de.overleaf.com/latex/templates/automatically-numbering-compounds-in-chemical-schemes/kybckmsxnshs>
In my case, the markers are not replaced, but instead under all six exemplary compounds the text "TMP1" or "TMP2" is written. Also the font inside the pictures is screwed up in respect to the model pdf from above.
What am I doing wrong? And while we're at it: how do I make my own TMP-labels? is it fine to just write "TMP" as a textblock in chemdraw?
Thanks in advance!

\section{Introduction}
Simulations for the geophysical phenomena of a fluid flow over weirs, under gates and submerged elands were studied in several theoretical and experimental works. These works deal with model problems of free-surface fluid flow over a topography or under floating submerged bodies. the theoretical problem is a
nonlinear boundary value problem which may be in certain cases, constrained by initial conditions (see \cite{ABWZ,1}).
The two-dimensional fluid flow over an obstacle or under a floating body, within the frame of the linearized theory of motion, has been investigated by several authors, for instance \cite{2,3,4,5}. The mathematical theory used in these investigations is inadequate to describe the important nonlinear aspects of the phenomenon. Using a certain procedure the solution for the velocity potential of the nonlinear problem is expressed as a power series in a certain small parameter \cite{1}. The above-mentioned linearized theory assumes the first term of such a series as a first approximation of the solution. the radius of convergence of this series is shown by Gouyon \cite{6} to be of the same order as that of the ratio of the free surface amplitude to the wave length. Hence, this theory is inadequate to deal with the propagation of long waves.
Different numerical techniques were developed to solve the nonlinear system of equations to which the original problem is reduced. Yeung \cite{7} present an exhaustive review of the numerical techniques which are widely applied to this system.
Analytical techniques, within the frame of the shallow-water theory, were used by several authors to investigate free-surface flows over certain non-horizontal bottoms, see \cite{8,9,10}.
Guli \cite{8} and Abou-dina and Helal \cite{10} studied the problem of the reflection and transmission of an incident progressive wave over a topography in shallow water using both of the Lagrangean an Eulerian description of the problem, respectively.
In the present work, we investigate the effect of a fixed vertical submerged barrier on the propagation of an incident wave inside a homogeneous fluid. Euler’s description is used and the problem is studied within the frame of the two-dimensional shallow water theory. The fluid is supposed to occupy an infinite channel of constant depth and the horizontal extent of the submerged barrier
is assumed to be small, see fig. \eqref{fig1}.
The analysis enables to separate progressive waves from local perturbations and shows the absence of reflected waves in the first order of approximation. These results are similar to those obtained for the case of nonhorizontal topograpgy by Ogilvie \cite{3}, Guli \cite{8} and Abou-Dina and Helal \cite{10}. The second order approximation of the solution is found to be the superposition of progressive wave and local perturbations. Analytical expressions are calculated for the local perturbations of the second order. For approximations of order higher than two, the expressions for the progressive waves contain a secular term
which increases monotonically with time and distance. This unacceptable result is due to certain aspects of the mathematical used procedure. For this reason, the procedure is modified by utilizing a suitable transformation of variables. The modification reduces the determination of the transmitted wave to be the
solution of the equation of Korteweg and de Vries ($\textbf{KdV}$).
As an illustration, the special case of the incident uniform flow is considered and the stream lines of the resulting flow are drawn.

Simulations for the geophysical phenomena of a fluid flow over weirs, under gates and submerged elands were studied in several theoretical and experimental works. These works deal with model problems of free-surface fluid flow over a topography or under floating submerged bodies. the theoretical problem is a
nonlinear boundary value problem which may be in certain cases, constrained by initial conditions (see \cite{ABWZ,1}).
The two-dimensional fluid flow over an obstacle or under a floating body, within the frame of the linearized theory of motion, has been investigated by several authors, for instance \cite{2,3,4,5}. The mathematical theory used in these investigations is inadequate to describe the important nonlinear aspects of the phenomenon. Using a certain procedure the solution for the velocity potential of the nonlinear problem is expressed as a power series in a certain small parameter \cite{1}. The above-mentioned linearized theory assumes the first term of such a series as a first approximation of the solution. the radius of convergence of this series is shown by Gouyon \cite{6} to be of the same order as that of the ratio of the free surface amplitude to the wave length. Hence, this theory is inadequate to deal with the propagation of long waves.
Different numerical techniques were developed to solve the nonlinear system of equations to which the original problem is reduced. Yeung \cite{7} present an exhaustive review of the numerical techniques which are widely applied to this system.
Analytical techniques, within the frame of the shallow-water theory, were used by several authors to investigate free-surface flows over certain non-horizontal bottoms, see \cite{8,9,10}.
Guli \cite{8} and Abou-dina and Helal \cite{10} studied the problem of the reflection and transmission of an incident progressive wave over a topography in shallow water using both of the Lagrangean an Eulerian description of the problem, respectively.
In the present work, we investigate the effect of a fixed vertical submerged barrier on the propagation of an incident wave inside a homogeneous fluid. Euler’s description is used and the problem is studied within the frame of the two-dimensional shallow water theory. The fluid is supposed to occupy an infinite channel of constant depth and the horizontal extent of the submerged barrier
is assumed to be small, see fig. \eqref{fig1}.
The analysis enables to separate progressive waves from local perturbations and shows the absence of reflected waves in the first order of approximation. These results are similar to those obtained for the case of nonhorizontal topograpgy by Ogilvie \cite{3}, Guli \cite{8} and Abou-Dina and Helal \cite{10}. The second order approximation of the solution is found to be the superposition of progressive wave and local perturbations. Analytical expressions are calculated for the local perturbations of the second order. For approximations of order higher than two, the expressions for the progressive waves contain a secular term
which increases monotonically with time and distance. This unacceptable result is due to certain aspects of the mathematical used procedure. For this reason, the procedure is modified by utilizing a suitable transformation of variables. The modification reduces the determination of the transmitted wave to be the
solution of the equation of Korteweg and de Vries ($\textbf{KdV}$).
As an illustration, the special case of the incident uniform flow is considered and the stream lines of the resulting flow are drawn.

\end{figure}
The origin of the Cartesian system of coordinates is fixed in the submerged obstacle. the axis \textbf{Ox} points along the direction of the incident-wave velocity, the axis \textbf{OY} is vertical upwards and the plane \textbf{Oxz} coincides with the free surface at rest. The bottom of the channel is impermeable and horizontal
\section{Main problem}
Consider an incident upstream wave inside a fluid layer with free surface and finite depth in an infinitely long channel. The bottom of the channel is horizontal

https://tex.stackexchange.com/questions/121743 | 1 | I have used the following command to change the color of references in the text to blue:
```
\hypersetup{ colorlinks,

however; the parentheses, semicolons and commas sometimes appear in black.
The only way I was able to fix this was by using the `\textcolor{blue}{\citeN{sampref1}}` so that all the text would appear in blue. But this is frustrating to do for more that 100 of references that I have.
Is there a solution for this problem?

https://tex.stackexchange.com/questions/687437 | 0 | I am trying to write a script that using texcount will output only the number of characters including spaces. I made a batch script which works, no problems there.
The problem is trying to run it in latex shell escape in overleaf using the \immediate\write18 environment. The problems seems mostly to be with how latex handles the special characters used in the batchscript. The script/latex code is as follows:
```
\newcommand{\quickcharcount}[1]{%
\immediate\write18{
texcount -1 -sum -merge -char -q main.tex > chars.txt
texcount -1 -sum -merge -q main.tex > spaces.txt
for /f "skip=1" %%G IN (spaces.txt) DO if not defined line set "nSpace=%%G"
for /f "skip=1" %%G IN (chars.txt) DO if not defined line set "nChar=%%G"
for /f "tokens=1*delims=:" %%G in ('findstr /n "^" spaces.txt') do if %%G equ 2 set "nSpace=%%H"
for /f "tokens=1*delims=:" %%G in ('findstr /n "^" chars.txt') do if %%G equ 2 set "nChar=%%H"
set /a "sum=nChar+nSpace"
echo %sum% > count.sum
}%
\input{count.sum}
}
```
Does anyone have experience with this, and know how to solve the problem?
EDIT:
I was told it was not possible with a bat script, so I have now written it as a shell script. But I am still struggling with getting it to work inside latex. You said it was somewhat restrictive with overleaf, so could this also be the reason here?
```
#!/bin/bash
char=$(texcount -1 -sum -merge -char -q main.tex)
space=$(texcount -1 -sum -merge -q main.tex)
nChar=${char%(*}
nSpace=${space%(*}

You have defined `\quickcharcount` to have 1 argument you don't use so I defined it with no arguments.
A newline in the source is a space so all your script is on one line.
You could use `^^J` to write a newline but here I just use the bash command
separator `;` You also need `\@percentchar` as `%` is a comment.

Deleting the block after the third `\else` (outlined on the left) does change the font, but it also messes up any linking settings and prints the glossary on a page in front of the title page and not lined up nicely, but in one block of text. By messing up linking, I mean that there are now blocks around the TOC entries, for instance.

| https://tex.stackexchange.com/users/120477 | Change geometry of last page | true | Generally, it would be useful to know the reason for the changed page layout of the last page. For example, if there will be a special content at that page, the change of the top margin could be bound to that content. Or if the content of the last page should just be bottom aligned, this also could have another solution. But because your question was more general, about changing the setting of `top` with `geometry` package for the last page, here is a suggestion for exactly this:
```
\documentclass[twoside]{scrartcl}
\usepackage[showframe]{geometry}
\usepackage{lipsum}
\makeatletter
\AddToHook{shipout/after}{%
\ifnum \c@totalpages=\numexpr\@abspage@last-1\relax

\global\@colht=\textheight % maybe not needed

After at least two LaTeX runs it results in:
For also changing the left or right margin or the height of the page header additional global changes of lengths could be needed, but this wasn't the question.
Just one additional note: Loading `geometry` already changes the margins of `scrartcl`. If you don't want this, you can use either KOMA-Script option `usegeometry` or `geometry` option `pass`.

https://tex.stackexchange.com/questions/687549 | 0 | As external software generates figures without labels similar to the figures included in the example, I am unable to reference them. However, I need to reference them in my text using e.g. `\ref{fig:1}`. ChatGPT proposed me a solution included below that will automatically add a label with an increasing number from a separate counter in the label, counting across sections that my figures are otherwises numbered within. Therefore, the links work and show the correct figure number, but when clicking them, you will always end up on the figure with the correct number in the first section (e.g., clicking figure 2.2 will send you to 1.2, 2.1 to 1.1).
I believe I am getting something wrong with the counters. Very happy for any advice. MWE below:

The hyperref package doesn't like this and produces a warning. Is there something simple I can do to prevent the warning? (I prefer to have no warnings.) I do want hyperref to create links for normal footnotes.
A more general question (which should answer the specific one): Is there a command that locally disables hyperref from creating a link?

Let's hope there are no real hyperref warnings in the text, because they would be silenced as well.

```
This renders “foo” as expected, but the node at `(0,1)` shows:
```
every pic quotes/.try,’,bar
```
I expected “'bar”.
Is this a bug or am I missing something?
Actually, I’m trying to pass 3 arguments to the pic style and according to the manual the quotes functionality should be good for 1 or 2 (to start with).
| https://tex.stackexchange.com/users/15894 | Is \tikzpictextoptions not supposed to contain the text after the quotes only? | false | The `'` is a special character that is taken care of by the `quotes` library so that a syntax like
```
"Foo"' Bar
```
is possible without having to do
```
"Foo" {', Bar}
```
which makes it easy to [`swap`](https://tikz.dev/tikz-shapes#tikz/swap) a node(/label/pin) with one key without having to use `,` and `{}`. The `'` will always be sneaked in with an extra `,`.
On `every pic quotes` being part of the `\pictextoptions`, I'd argue this is an oversight of the manual (where even `'` isn't really transformed in the example). This behaviour is consistent with all other `quotes` cases
* `every pin quotes`,
* `every label quotes` and
* `every edge quotes`.
Where the latter is the only on defined by default with [`auto`](https://tikz.dev/tikz-shapes#tikz/auto).
This would also be the only one where `'` = `swap` would make sense out of the box unless your pic's node is also along a path segment.
Of course, you can always change the definition of `'` or `swap` inside `every label/pin/pic quotes` so that the shorthand `'` has a more useful meaning when used with labels, pins or a pic's text.

| https://tex.stackexchange.com/users/289569 | How to set Arial Narrow font for my entire document with font size 10.5pt? | true | ### Setting the Font
First, check that you have Arial Narrow installed. **TeX on Windows cannot find fonts unless they are installed for all users.** To test how XeTeX looks it up, run `fc-match "Arial Narrow"` from the command line. To test how LuaTeX looks it up, run `luaotfload-tool --find "Arial Narrow"`. If you install a font the default way, without Administrator permission, Windows puts it in a hidden directory that TeX engines don’t know about. If you did that by accident, make a copy of the font file, uninstall it from the Control Panel, and reinstall for all users.
You might also be able to load the font by its filename, which is the recommended way. If you have the file `C:\Windows\Fonts\ARIALN.TTF`, this should work for you:
```
\usepackage{fontspec}
\defaultfontfeatures[ARIALN]{
UprightFont=*,
BoldFont=*B,
ItalicFont=*I,
BoldItalicFont=*BI,
Extension=.ttf }
\setmainfont{ARIALN}
\setsansfont{ARIALN}
```
If you happen not to have it, Arial Nova Condensed is available *gratis*.
### Setting the Font Size
What TeX calls `10pt` is the slightly-smaller European point. What Word and most other software calls a “point,” TeX calls a `bp`, or “big point.” One way to get what Microsoft Word calls “10.5-point” is:
```
\usepackage[fontsize=10.5bp]{scrextend}
```
You could also load the `scrartcl` class instead of `article`, to get the extra features of Koma-Script
However, if “10.5pt” is really a workaround for `10pt` being smaller in TeX than Word, and what you actually want is what Word calls 10 points, say `10bp`. (Similarly, if you want 2 cm, you should say `2cm`, not `0.8in`).
### Other Bugs in Your Document
You seem to be copying someone else’s preamble. Worse, you seem to be copying from somebody who copied from somebody else. You ended up with several packages twice, or that are incompatible with each other.
Some changes you need are:
* Load `\usepackage[svgnames]{xcolor}`, once, before `fontspec`, to get `NavyBlue`.
* Don’t load `fontenc` or `newtxtext` (which load 8-bit fonts from last century) with `fontspec`.
* Don’t load `newtxmath` here. It loads math mode (which I doubt a document that starts this way would need) in a legacy format, and also loads a font that clashes horribly with Arial Narrow. If you need to use math mode along with `fontspec`, [you can pick from one of the samples here.](https://tex.stackexchange.com/questions/425098/which-opentype-math-fonts-are-available)
* Set the color of your headers once, with `\addtokomafont` if you’re using the `scrartcl` document class, or a package such as `titlesec` otherwise. Don’t put a `\color` command in each individual section title.
* The package option to get letter-size paper is `letterpaper`, not `letter`.
* Remove any package you aren’t actually using.

\catcode32=13\def {o} \bye
```
how does TeX know to tokenize the space after `\def` as an active character?
**Details:** The correct result is `o`. First, we set spaces (ASCII 32) to be active characters (category 13); then, we define them to print `o`; then, we add a space, printing `o`, and finish.
How does the parser recognize the end of the literal number `13`? A literal number can't contain an unexpandable control sequence, like `\def`. But it *can* contain an expandable control sequence like `\if`, and we can't know which this is until we finish reading it and look it up. So, until we reach the end of parsing the `\def` token, we don't know where the end of `13` is.
It gets hairy here. Multi-character control sequences absorb the following space. So before the `\catcode` assignment ran, the `\def` would have absorbed the following space. But to run the `\catcode` assignment, we have to tokenize up to the end of the `\def` token.
So, how does TeX know not to eat that space?
| https://tex.stackexchange.com/users/259978 | How does TeX know whether to eat this space if its catcode is about to change? | false | From experimenting with things such as
```
\catcode`Z=13Z
```
and
```
\def\defZ{W}\catcode`Z=13\defZ{XY}
```
I feel that in trying to terminate the catcode assignment TeX scans ahead with current pre-existing catcode regimen. So it will see `\def<space>` decide that `\def` terminates the assignment, then resume its scanning and catcode assignments (unlike in a `\futurelet` which would have frozen the catcode) so the space is now active.
Not an authoritative answer because not based on actually going to the TeX sources...
---
The following example
```
{\catcode`Z=13 \gdefZ{WWW}}\catcode`Z=13ZZ
```
which prints out ZWWW shows that at least here the catcode 11 Z (the first one after 13) is not reinterpreted as catcode13.
This must be added to my earlier babblings (the additional babble being that some catcode may get frozen; in OP, it is farther away though, but let's wait for the correct answers).

1. While in the process of gathering tokens that form the second TeX-⟨*number*⟩-quantity of the `\catcode`-assignment, that TeX-⟨*number*⟩-quantity is found to be an ⟨*integer constant*⟩ consisting of a sequence of ⟨*digit*⟩-tokens with leading ⟨*digit*⟩-tokens `112` and `312`.
2. As the ⟨*digit*⟩-token `312` is considered a component of the ⟨*integer constant*⟩ and thus not suitable for terminating the process of gathering tokens belonging to the ⟨*integer constant*⟩, more tokens are to be tokenized and expanded if expandable, until finding a token suitable for terminating the process of gathering tokens belonging to the ⟨*integer constant*⟩ as not considered a component of the ⟨*integer constant*⟩.
3. Thus, in the course of forming more tokens probably belonging to the second TeX-⟨*number*⟩-quantity of the catcode-assignment, TeX gathers characters denoting the next token.
4. Hereby TeX encounters the character `\` which has category code 0 (escape) and realizes that characters denoting a control sequence token are to be gathered. After realizing this, TeX encounters the character `d` and due to the character `d` having category code 11 (letter) realizes that characters denoting a control word token are to be gathered.
5. So, TeX also gathers the character `e` and the character `f` which both have category code 11 (letter).
6. Then TeX encounters the space character, which at that time has category code 10 (space). Characters not of category code 11 (letter) at the time of tokenizing are not considered components of names of control word tokens. Thus the space character terminates the process of gathering characters denoting a control word token and TeX appends the control word token `\def` to the token stream and switches the reading-apparatus to state S (skipping blanks).
The token `\def` is not considered a component of an ⟨*integer constant*⟩, thus the process of gathering tokens belonging to the ⟨*integer constant*⟩/the process of gathering tokens belonging to the second TeX-⟨*number*⟩-quantity of the catcode-assignment is terminated and the catcode-assignment is performed.
Thus, when processing the space character, which terminated gathering characters for the `\def`-token, takes place, the category code of the space character is 13 (active). As state S (skipping blanks) only affects characters of category code 10 (space), the space character gets tokenized as an active character token.
If you like to get familiar with how in TeX the stage of tokenization/processing single characters of a line of .tex-input is intertwined with other stages of processing (stage of expansion / stage of performing assignments), try to figure out why
`\catcode`\.=0\def.macro{replacement}\macro\bye`
works out while
`\catcode`\.=0.def.macro{replacement}\macro\bye`
yields error-messages about `.macro`/`\macro` being undefined.

So, how does TeX know not to eat that space?
| https://tex.stackexchange.com/users/259978 | How does TeX know whether to eat this space if its catcode is about to change? | false | It's simple, actually.
1. The `\catcode` token alone tells TeX that a category code assignment is to be performed;
2. in this case, TeX looks for an 8-bit ⟨number⟩ (it's 21-bit for XeTeX or LuaTeX);
3. upon having found it, TeX looks for an ⟨optional equals⟩ (gobbling a space after `=`, if both are present);
4. TeX looks for a 4-bit number.
How the ⟨number⟩ can be specified is too long to describe. In your case, both the required ⟨number⟩s are explicit constants, and a category 10 space would be gobbled after the sequence of digits.
It's also important to remember that an entire line of input is read, and the end-of-record is replaced by the `\endlinechar`, after throwing out trailing spaces, but the characters haven't yet been tokenized: TeX tokenizes the input only when it needs to.
So the following code lines are completely equivalent:
```
\catcode32=13\def {o} \bye
\catcode32 =13\def {o} \bye
\catcode32= 13\def {o} \bye
\catcode32=13 \def {o} \bye
\catcode32 = 13\def {o} \bye
\catcode32 =13 \def {o} \bye
\catcode32 = 13 \def {o} \bye
```
Indeed, the input
```
{\catcode32=13\def {o} }\par
{\catcode32 =13\def {o} }\par
{\catcode32= 13\def {o} }\par
{\catcode32=13 \def {o} }\par
{\catcode32 = 13\def {o} }\par
{\catcode32 =13 \def {o} }\par
{\catcode32 = 13 \def {o} }\par
\bye
```
produces seven o's. Your case is the first one, where `\def` cannot be interpreted as a digit: the token is put aside to be reread after the assignment has been performed.
Let's examine
```
\catcode32=13 \def {o} \bye
```
that's what you probably want to know about (the other two with a space after 13 are similar). When TeX has scanned the `=`, it proceeds to look for a 4-bit ⟨number⟩. It finds `1`, so it knows that an explicit constant follows. Next comes `3` and further comes a space. No category code assignment has yet been done, so this space is given category code 10 and terminates the lookup for digits. Now TeX know what category code to assign, it performs the assignment and discards the category 10 character that follows.
Maybe you can ask what would happen with
```
\catcode32=13 \def {o} \bye
```
Exactly the same, because after scanning a category code 10 character, TeX enters the state “skipping blanks”, so the following category 10 characters are ignored. This action of skipping blanks happens before the assignment of category code is performed, because TeX wants to “normalize” the input stream.
Exercise: predict the output of
```
\catcode32=13\def {o} \ \bye
```
(there are two spaces after the backslash).

why are these do not render the same?
| https://tex.stackexchange.com/users/231103 | what does [length] after a `\\` mark mean | false | To begin with, LaTeX commands can take both required and optional arguments. Required arguments are (generally) enclosed by curly braces, while optional arguments are enclosed by square brackets.
Next, if the string
```
mmmmm\\[-0.33em]
```
occurs inside an `array` or a `tabular`-like environment, the sub-string `\\` is the instruction to insert a line break and `[-0.33em]` represents an *optional* argument to the `\\` instruction. If the argument, which is supposed to be a length, is a positive, additional vertical whitespace -- in the amount of that argument -- will be inserted; it it's negative, that amount will be subtracted from the default amount of vertical space that's inserted by `\\`.
(Aside: If you use `\\` *outside* of `array` and `tabular`-like environments, it's quite likely that you're doing something wrong...)
In contrast, `\hspace` is a text-mode command that serves to insert or subtract *horizontal* space. Incidentally, to LaTeX, `\hspace{0pt}` is *not* the same as "doing nothing" -- inserting "zero-length whitespace" can have significant and (if used correctly) very handy use cases.
In short, there's no reason to believe that `\\[-0.33em]` and `\hspace{-0.33em}` would, let alone *should*, produce the same outcome.

**Details:** The correct result is `o`. First, we set spaces (ASCII 32) to be active characters (category 13); then, we define them to print `o`; then, we add a space, printing `o`, and finish.
How does the parser recognize the end of the literal number `13`? A literal number can't contain an unexpandable control sequence, like `\def`. But it *can* contain an expandable control sequence like `\if`, and we can't know which this is until we finish reading it and look it up.

It gets hairy here. Multi-character control sequences absorb the following space. So before the `\catcode` assignment ran, the `\def` would have absorbed the following space. But to run the `\catcode` assignment, we have to tokenize up to the end of the `\def` token.
So, how does TeX know not to eat that space?
| https://tex.stackexchange.com/users/259978 | How does TeX know whether to eat this space if its catcode is about to change? | true | It is true that if the token processor creates a token and it is sent to the expand processor, then the once assigned catcode cannot be changed (there are several exceptions like `\string`, `\detokenize` etc. but is out of our current focus).
But your example
```
\catcode32=13\def {o} \bye
```
doesn't meet the second part of the sentence: the space after `\def` is waiting for processing at the token-processor level. It is not sent to the expand processor. The token processor recognizes the space after `\def` twice. Firstly, when `\def` control sequence is constructed (space has catcode 10 in this time). Then the token processor switches to the "skipping spaces" state, it sends the `\def` to the expand processor, and it keeps the space character for further processing. Expand processor cannot expand `\def`, so it tells the main processor that the number reading is finished, and the main processor finalizes the `\catcode` assignment and runs `\def`. It deactivates expand processor at this place and asks to the token processor to move the next token. The token processor gets waiting for space and creates a token from it using current catcode 13. Its "skipping spaces" state is finished because the created token isn't space with category 10. It sends the token space/13 to the main processor.
The main lesson learned from it is: the token processor doesn't definitely create the pair character/catcode until it is sent to the next level of processing (expand processor, main processor).

specifies five columns: four `c` columns and one `l` column. In the first row:
```
\thead{Risk level} &\thead{Precision} & \thead{Recall} & \thead{f1-score} & \thead{Support}\\
```
you are indeed using these five columns. But all other columns like:
```
& High & .95 & .93 & 1.00 & 60\\
```
are using six columns: an empty one before the first `&` and five columns with contents.
So you either have to specify one more column or remove the empty column in each row but the first. Looking to the contents, IMHO removing the empty column would be best. I would additionally recommend to use `S` columns of package `siunitx` for all columns but the first one:
```
\documentclass{IEEEtran}

\renewcommand{\theadfont}{\footnotesize\bfseries}
\usepackage{lipsum} % for dummy text filler
\begin{document}
\begin{table}

\bottomrule
\end{tabular}
\end{table}

```
For example for the last column it could be useful, to specify the decimals. See the `siunitx` manual for more information.

https://tex.stackexchange.com/questions/7588 | 12 | I’d like to install a package (microtype 2.5 beta 4) under TeX Live that isn’t available in the official repository.
Now, I know that it’s usually enough to put the package under `~/texmf/tex/latex/` but I was wondering if I couldn’t use `tlmgr` to do the grunt work for me.
In particular, I noticed that `tlmgr` has a `--repository` option that can be used to pass it a local repository path. However, the following command unfortunately fails (understandably, since there is no TeX Live database file `texlive.tlpdb` there to read from):
```
wget http://xetex.tk/mediawiki/images/1/1c/Microtype.tds.zip
unzip Microtype.tds.zip
tlmgr --repository=./Microtype.tds/ update microtype
```
I was wondering if there was still a possibility to make this work.
| https://tex.stackexchange.com/users/42 | Install downloaded package via tlmgr | false | This is how I add manually a new package (ex: xyz) on Linux Fedora:
`sudo dnf install 'tex(xyz.sty)'`.
For the Debian-based distros it should be something like (I've not tried):
`sudo apt-get install 'tex(xyz.sty)'`.
This puts the package under the system-wide home for Tex packages and not user based one. For Fedora it is:
`/etc/share/texlive/texmf-dist/tex/latex/`.

How can I prevent this warning message?
Could be related to [How to ignore "Wrong length of dash may have been used." inside \cite and \newcite](https://tex.stackexchange.com/q/350485/127048) but I am not drawing any line, it was just string in a text.
| https://tex.stackexchange.com/users/127048 | ChkTeX: Wrong length of dash may have been used | false | So, I found three ways of getting rid of the warning (all producing different outputs):
`100K100$-$873` - for a minus symbol
`100K100~-~73` - for space-dash-space
`100K100{-}873` - for just a normal dash
Probably the third is what you were aiming for... as it displays the same text as `100K100-873`
~ is the inline space symbol, which means "here should be one (and only one) space"

https://tex.stackexchange.com/questions/687654 | 0 | I am reading data for a supplementary info from different CSV files using the csvsimple package.
To display things nicely, I have written my own csvstyle, as all the CSV files have the same format.
For certain tables, the data is too long and requires multiple pages. This works easily by changing the csvstyle to use `long tabularray` instead of `tabularray`.
A problem occurs now, when I want to add a caption to this long table: if I wrap the `\csvreader` and the `\caption` in e.g. `\begin{table}`, the table does not do any page breaks anymore; if I use e.g. `\begin{longtable}` instead of `\begin{table}`, compilation does not work anymore, each row gets another header row, and things like that, depending on the wrapper.
What is the correct procedure to add a caption here?
Below, a minimum reproducible example with the \begin{table}, that does not do page breaks.

https://tex.stackexchange.com/questions/687714 | 2 | There are two no operation functions in LaTeX3 called `\prg_do_nothing:` and `\scan_stop:`. What is the difference between them? Which one is preferable?
| https://tex.stackexchange.com/users/241621 | \prg_do_nothing: vs \scan_stop: | true | They do different things. The functions `\prg_do_nothing:` is expandable, and is documented as expanding to nothing at all. This means that for example
```
\tl_set:Nx \l_tmpa_tl { \prg_do_nothing: }
\tl_if_empty:NTF \l_tmpa_tl ...
```
will take the `true` branch.
On the other hand, `\scan_stop:` is not expandable, so the same setup
```
\tl_set:Nx \l_tmpa_tl { \scan_stop: }
\tl_if_empty:NTF \l_tmpa_tl ...
```
takes the `false` branch. The `\scan_stop:` function also acts as a terminator for various low-level TeX constructs, which `\prg_do_nothing:` does not.
Which you want depends on your use case. If you are working by expansion and need a marker that will 'disappear', `\prg_do_nothing:` is the right choice. If you need a marker that will *typeset* nothing but that will surive `x`/`e`-type expansion, you want `\scan_stop:`.

I tried looking into the `test.log` but couldn't find any meaningful debug info.
1. What is the proper way to pipe the output of a command like `mktemp` into another command?
2. What is a good general way to debug obscure-looking latex compile errors?
3. I've seen [references](https://tex.stackexchange.com/questions/137111/how-to-actually-close-a-write-stream) to a `\tempfile` command, but I just get: `! Undefined control sequence. \mktemp -> \tempfile` when trying to use it. Where is this `\tempfile` command defined?
I should note that I have modified my `textmf.cnf` to allow the commands `qrencode` and `mktemp`:
```

https://tex.stackexchange.com/questions/687705 | 0 | We are aware that Microsoft Word has a feature called ink Equation that allows the user to write a formula with a light pen, even if the formula is complex, and then convert it into a real equation with an acceptable font. Obviously, this is an excellent option, since it is not necessary to use multiple commands to write a lengthy equation; instead, one can simply write the equation as seen.
My query is: Is there a latex editor that includes this feature? If the answer is affirmative, which editor has this capability?
| https://tex.stackexchange.com/users/94003 | ink Equation in Latex | true | Ok, the request is for a primer in websearch.
It's an `iterative process`:
* you start somewhere
* you refine your search
* you select best solutions
### Potential shortcuts
Whatch the right side under `Related`, showing links within this place. E.g. inspecting these lead you to either a solution or: new search terms. `Take notes` and watch the *Related* there, as well ...
[What are the Open source WYSIWYG Independent Web Equation Editors available on LaTeX/MathML](https://tex.stackexchange.com/questions/5146/what-are-the-open-source-wysiwyg-independent-web-equation-editors-available-on-l?rq=1)
[Visual Equation Editor to LaTeX Code](https://tex.stackexchange.com/questions/18155/visual-equation-editor-to-latex-code?rq=1)
### Iterations
Start somewhere, e.g. using your title as search term:
[ink Equation in Latex](https://www.google.com/search?q=ink%20Equation%20in%20Latex) . Almost the first entry leads me to [Mathpix](https://mathpix.com/equation-to-latex) , which probably is already what you are looking for.
Check out the other links listed from this search term alone.
### Refinements
* consult your notes, for synonyms, technical terms, nerdy slang etc.
* same for the websites you followed by aboves links
* use the search engines proposals as well, see screenshots
* and of course try *alternative mathpix* and similar as serach term
As is:

TRY your findings in this sites search box as well, e.g. <https://tex.stackexchange.com/search?q=mathpix>, which leads to e.g. [Tikz tools like mathpix ？](https://tex.stackexchange.com/questions/501659/tikz-tools-like-mathpix)

How to find what I want by a websearch?
Answer | gpt-3.5 Model
To find what you want by a web search, you can use filters to narrow down your results. Here are some tips to help you out:
Use site or domain filters to search for results from a specific website or domain.
Try filtering results based on where your search terms appear in the page, such as the title, text, or URL.
Use SafeSearch to remove explicit results.
Filter by file type to find specific formats like .pdf, .xls, or .ppt.
Use usage rights to find pages that have license information attached to them.
In addition, you can try using alternative search engines like SearX, which offers unbiased results from several sources and allows for customization and hosting on your own server.

https://tex.stackexchange.com/questions/687710 | 3 | I'm trying to store the text output of a shell command `mktemp` and reuse it later in another latex command. I'm attempting to do this using `\savebox` and `\usebox` as below. When using `\usebox` outside a command, the saved text is printed correctly. However, when used inside other commands like `\write18` and `\includegraphics`, the `\usebox` command appears to not be macroexpanded correctly:
```
\newcommand{\mktemp}[0]{
\input{|"mktemp"}
}
\newcommand{\hrefqr}[2]{%
\tracingall
\newsavebox{\tmp}
\savebox{\tmp}{\mktemp}
%% verify that \tmp is the same file and not repeated mktemp calls
\usebox{\tmp} \\
\usebox{\tmp} \\

\href{#1}{#2 \includegraphics[]{\usebox{\tmp}}}
}
\begin{document}
\hrefqr{www.example.com}{This is example.com}
\end{document}
```
From the logs:
```
\write->qrencode www.example.com -o \usebox {\tmp }
\usebox ->\protect \usebox
\usebox #1->\leavevmode \copy #1\relax
#1<-\tmp
\leavevmode ->\unhbox \voidb@x
runsystem(qrencode www.example.com -o \protect \unhbox \voidb@x \copy \tmp \rel
ax )...executed safely (allowed).
```
And later:
```
! LaTeX Error: File `\usebox {\tmp }' not found.
```
from the expansion of:
```
#1<-This is example.com \includegraphics []{\usebox {\tmp }}
```
What am I doing wrong?
| https://tex.stackexchange.com/users/87864 | usebox macro not expanded? | true | You can't store text in a box and retrieve it by macro expansion. When you do `\savebox{\tmp}{some text}` the argument is stored in the box register as *already typeset*.
Here's a working implementation. I create a directory, rather than a file, and in it I create `temp.png`, otherwise `\includegraphics` wouldn't be able to determine its size. See <https://stackoverflow.com/a/59638023>.
If your version of `mktemp` supports `-suffix`, you can use it, see later for details.

https://tex.stackexchange.com/questions/687467 | 0 | I am currently trying to use the latest version of `ClassicThesis` (with `ArsClassica` style), but I have some problems with the look of some elements in the table of content.
In the showcase example that is provided [on the home page of this package](https://bitbucket.org/amiede/classicthesis/wiki/Home), in the table of contents we can see that parts, chapters, appendix and bibliography are all uppercase, but if I compile that project, they will not be as such. How can I make them look like they appear in the example `.pdf`, i.e. uppercased?
Here is an example that you can easily compile:
```
\documentclass[twoside, openright, titlepage, numbers = noenddot,
headinclude, footinclude, cleardoublepage = empty,
abstract = on, BCOR = 5mm, paper = a4, fontsize = 11pt]{scrreprt}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\usepackage[eulerchapternumbers, eulermath, beramono, palatino, style = arsclassica]{classicthesis}
\begin{document}
\frenchspacing
\raggedbottom
\tableofcontents
\chapter{I am a chapter} % This should be uppercase!
\lipsum[1]
\section{I am a section}
\lipsum[1]
\subsection{And I am a subsection}
\lipsum[1]
\end{document}
```
I downloaded and compiled the example project provided with `version 4.2` and everything looks as it should, but since I am not an expert in LaTex programming, I do not know how to force the same behavior in its latest version.
| https://tex.stackexchange.com/users/298246 | Chapters in ClassicThesis' table of content are not uppercase | true | Thanks to @user691586, I managed to fix the style of both chapters and bibliography with the following:
```
\newcommand{\tocFixedChapter}[1]{\chapter{\spacedlowsmallcaps{#1}}}
\renewcommand{\tocEntry}[1]{\protect\numberline{}{\spacedlowsmallcaps{#1}}}
```
Now the result is also coherent with the `ArcClassica` package!
This problem can be considered solved. Thanks!

* instead of repeating your equation multiple times with and without the boxes, use the `overlay-beamer-styles` library to define on which overlays the fill colour shall be visible
* I suggest to have a look at the `tikzmarks` library. This way you wouldn't have to reinvent the wheel
* a lot of the packages you load are unnecessary. You should clean up your preamble and only load the package which you need for your presentation.

1. How `TeX` "deals with spaces"?
=================================
The rules applied to spaces (except inside `verbatim`/`math` mode or when `\obeyspaces` is in effect) are listed in this [Martin Scharrer's answer](https://tex.stackexchange.com/a/34847/262081).
For deeper explanations and "traps" regarding how `TeX` "deals with spaces":
* [Mico's answer](https://tex.stackexchange.com/a/566580) (for beginners this answer is quite complete, very pedagogical and plenty of practical examples).
* [TH.'s answer here](https://tex.stackexchange.com/a/7459/262081).
* [egreg's answer](https://tex.stackexchange.com/a/74541/262081) (introducing also the three TeX *modes*: horizontal, vertical or math).
* [another egreg's answer](https://tex.stackexchange.com/a/19955/262081) introducing the use of `\relax`, `\ignorespaces` and also the issues related to spaces after a constant number (and much more!).
* [This blog](https://texhacks.blogspot.com/2009/10/spaces-in-tex.html) introducing the different *states* of TeX when reading input.
* Chapter 8 of *The TeXbook*.
2. Practical recommendations concerning the use of the percent symbol
=====================================================================
1. Use a `%` when you want `TeX` "[to exclude everything that's on the remainder of the current input line from further processing](https://tex.stackexchange.com/a/566580)" (including the "invisible" end-of-line character), useful for writing a comment for e.g.
2. **No need to use `%` sign in preamble** (except in macro definition, see below). So NO need of `%` after the closing `}` of a macro definition.
3. **No need to use `%` sign between two consecutive undelimited arguments** ([details here](https://tex.stackexchange.com/a/19955/262081)):
Then `\parbox {3cm} {text}` is equivalent to
```
\parbox
{3cm}
{text}
```
4. In macro definition [[details here](https://tex.stackexchange.com/a/74541/262081)]:
**A `%` will prevent from possible extra spaces** before AND after the word `bar` in the following example (unless the macro is used in math mode):
```
\newcommand{\foo}{%
bar%
}
```
Which is equivalent to `\newcommand{\foo}{bar}` **OR**:
```
\newcommand{\foo}{%
bar}
```
But it is not optimal because in some cases (depending on the context at the macro "call"), there will be no spurious spaces "added" before and/or after the word `bar` in the output, then the `%` signs will be unnecessary (but not problematic).
*So, if you really wants to optimise/minimise the use of the `%` sign in your macro definition, then take a look at this [egreg's answer](https://tex.stackexchange.com/a/74541/262081) and see also [ShreevatsaR's answer](https://tex.stackexchange.com/a/420561/262081) for good practice regarding macro writing.*
5. **Never put a `%` sign just after a constant number** but always PUT a space or a new line or a `\relax` instead (for e.g. - hereafter the `_` symbol stands as a space character - do `\ifnum\mycounter<13_` or `\mycount=123_` or `\mycount=123\relax` but NOT `\mycount=123%`), [details here](https://tex.stackexchange.com/a/19955/262081) and [here](https://tex.stackexchange.com/a/107697).
* *About the use of `\relax` (especially in "incomplete glue assignment") an possible issues see [this answer](https://tex.stackexchange.com/a/19955/262081) and also [this one](https://tex.stackexchange.com/a/420531/262081).*
6. **Put a `%` between two consecutives `\end{subfigure}` and `\begin{subfigure}`** or `\end{minipage}` and `\begin{minipage}` if you want to avoid undesired space (which could induce non aligned `subfigure` or `minipage`, e.g. and detailed explanation [here](https://tex.stackexchange.com/a/407620/262081)) BUT an `\hfill` will do the trick (even "better/cleaner") also ([see here](https://tex.stackexchange.com/a/605499/262081)).
7. **No need to put a `%`** after a control sequence (e.g. `\foo`) because the space is already ignored.
8. **In LaTeX3 syntax**, spaces are ignored in macro definition unless you explicitly specify the space with a `~` character (see [Leo Liu's answer](https://tex.stackexchange.com/a/19927/262081)).

| https://tex.stackexchange.com/users/297655 | How to I add \textit into a table and color to different parts of my table? | false | I don't know how the "iceberg" color is defined. In the code below, I load the `xcolor` package with the option `svgnames` in order to access a prefefined color labelled "Linen". I suggest using the `p` column type, which allows automatic line breaking, for the combination of the three underlying columns.
Since there's nothing in the code that's specific to the `longtable` environment, I've chosen to employ a basic `tabular` environment.
```
\documentclass{article} % or some other suitable document class
\usepackage{array} % for \extrarowheight macro
\setlength\extrarowheight{2pt} % for a less-cramped "look"

================================
1. In the middle of a control sequence.
\ta%
u
will not be reconstituted into `\tau`. A control sequence must be input as an unbroken unit.
2. After a number or <dimen> that is being used in an assignment. TeX will continue reading until the next token is definitely not numeric, or in the case of a <dimen> not `plus` or `minus`. Use `\relax` instead.
These exceptions are already covered, but "buried", so a more prominent reminder is warranted.
Another possibility, not as easily identified and often not mentioned in user documentation, is insertion of "padding" by a package, as in this example.
```
\documentclass{article}
\usepackage{tcolorbox}
\newcommand{\pink}[1]{\colorbox{red!20}{#1}}

This isn't usual, but action by a package should be considered when more likely possibilities fail to cure the problem.

The default highlighting in emacs works somewhat differently for `$…$` and `\(…\)` in the scope of `\emph{…}`:
The difference in highlighting is not only a question of taste (similar to the question of whether you like a BMW or a Mercedes more) but also important due to <https://tex.stackexchange.com/a/59195>. Apart from these details, there's not too much of a difference for a human typesetter. Personally, I switched from `$…$` to `\(…\)` a few years ago and probably make less errors since then (though I got more proficient, I tend to think that the increased quality is also due to this switching).

https://tex.stackexchange.com/questions/86976 | 6 | I am trying to define only the non-zeros elements in a sparse matrix, thus using some `\vdots` where the entries are zeros and specifying the row when needed (using the `blockarray` command, with `\usepackage{blkarray}` in the preamble). My matrix only has 2 columns (or 4), so I can't center the `\vdots` like I would like (the problem would be solved if the matrix had an odd number of columns). Here's an exemple:
```
$\begin{blockarray}{ccc}
\begin{block}{[cc]l}
\vdots \\
a & b & /K-1 \\
c & d & /K \\
\vdots \\
\end{block}
\end{blockarray}$
```
As you can see in this example, while I specified to center the entries inbetween `[` and `]`, the `\vdots` are centered on the first column. If I replace `cc` by any combination of `r`, `c`, and `l` it is still not satisfying. Also if I put the `\vdots` between any number of `&` on the right and/or on the left it still doesn't work.
The other solution I have (but not satisfactory either) is to add another column:
```
$\begin{blockarray}{cccc}
\begin{block}{[ccc]l}
&\vdots& \\
a & & b & /K-1 \\
c & & d & /K \\
&\vdots& \\
\end{block}
\end{blockarray}$
```
But as you can see now the non-zeros entries are too far apart and the result is not really pretty.

\begin{document}

% does not work (see error below):

\end{document}

% probably meant to type \&.
```
To get at least the row labels displayed at the correct side of the matrix, I
wanted to use the starred version of `\bordermatrix`, but that did not work (as
opposed to given in Voss's mathmode guide). Also, the matrix entries are not
right aligned. How can I create such a matrix? Is there a way to do this with `amsmath`?
**UPDATE**
Thanks to the link by Werner, a minimal example is this:
```
\documentclass{article}
\usepackage{blkarray}
\newcommand{\matindex}[1]{\mbox{\scriptsize#1}}
\begin{document}
\[
A=\begin{blockarray}{rrl}
\matindex{1} & \matindex{2} & \\
\begin{block}{(rr)l}
\,100 & b\phantom{\,} & \matindex{row 1} \\
2 & 12 & \matindex{row 2} \\
e & f & \matindex{ABDC} \\
\end{block}
\end{blockarray}
\]
\end{document}
```
It's just a quick hack to get a bit more horizontal space between the parentheses and the matrix entries.

Note that `minimum width` affects the circumcircle, whereas `inner sep` affects the incircle.

Alternatively I could accept reformating, but I don't know how to do it. I mean make journal title display like book title (for example `Journal title` without quotation marks in cursive), and make journal name field display with plain text without cursive.
It's out of the scope of the question but I also can't figure out how to remove comma between author name and surname. It displays `Doe, J.` but should be `Doe J.`.

| https://tex.stackexchange.com/users/289855 | Removing comma from journal title in biblatex | true | This comma placement is typical for American English: Following punctuation is moved inside quotation marks even if it does not "logically" belong there. See <https://en.wikipedia.org/wiki/Quotation_marks_in_English#American_style>.
This behaviour is usually only enabled for `biblatex`'s American localisation and not the generic `english`, but `biblatex-ieee` requests it explicitly with `\uspunctuation` (see [l. 34 in `ieee.bbx`](https://github.com/josephwright/biblatex-ieee/blob/7f67eea42f55ee0c27c8358dd7cd64bf47ad4a4c/ieee.bbx#L34).) You can counter that with a simple `\stdpunctuation`.
Usually `\uspunctuation` and `\stdpunctuation` should be used inside `\DefineBibliographyExtras`, but since `biblatex-ieee` uses it outside, we will counter it outside as well.

As you see, braces around the items are removed, which can have bad consequences in case wrong input such as `\bfseries Test3` is used (with or without braces). To be safe from such input errors, you can use a two-step approach: we split the list at commas and then surround each item by braces.

https://tex.stackexchange.com/questions/687834 | 2 | I am using the nice package `lua-widow-control` to slightly improve the appearance of the document. However, the warning messages "Widow/Orphan/Broken Hyphen NOT removed on page ..." was too long (contain too many lines), and when the document becomes lengthy, a large number of such warning messages can sometimes drown out other important warnings. I wonder if there is some way to change these messages from the level "Warning" into "Info" when the document is not finalized?
Below is an example of such a warning message.
```

| https://tex.stackexchange.com/users/194994 | lua-widow-control: is it possible to change warnings into infos | true | The message comes from
```
--- When we are unable to remove a widow/orphan, print a warning
---
--- @return nil
local function remove_widows_fail()
warning("Widow/Orphan/Broken Hyphen NOT removed on page " .. pagenum)
```
in `texmf-dist/tex/luatex/lua-widow-control/lua-widow-control.lua`
as such it is a locally defined function call (`warning`) inside the `local` declaration. So by design you can't really patch that from the outside.
You could however copy that file to the current directory (or anywhere earlier in the path) then around line 242 you see
```
warning = function(str) luatexbase.module_warning(lwc.name, str) end
info = function(str) luatexbase.module_info(lwc.name, str) end
```
and if you change `_warning` to `_info` then `warning()` will be like `info()` and only write to the log

https://tex.stackexchange.com/questions/687763 | 0 | I am using the `listings` package for displaying source code, and want to reformat the numbering to use the `oldstylenums`.
The problem comes when using `microtype`, as it throws errors for every line of code in the listing like this
```
Argument of \MT@res@a has an extra }. import
Paragraph ended before \MT@res@a was complete. import
Extra \else. import
```
* Disabling `microtype` makes LaTeX compile.
* Not reformatting the numbering makes LaTeX compile.
* Disabling `hyperref` makes LaTeX compile.
Is there a way to reformat the numbers without getting a `microtype` error, nor disabling one of the two fundamental packages `microtype` and `hyperref` for my document?
Here is my minimal, non-working example. Doing any of the above points will make it run.
```

```
| https://tex.stackexchange.com/users/281886 | Error between microtype, hyperref, and listings when setting oldstylenums for listings | true | Thank you to Ulrike Fischer for the comment above.
I thus found the working solution to be to define the number function outside the style call:
```
\newcommand\epicNumbers[1]{\oldstylenums{#1}}
```
and then calling that function inside the `lstdefinestyle` call, like this:
```
\lstdefinestyle{PythonStyle}{
language=Python,
...,
numberstyle=\ttfamily\scriptsize\color[rgb]{0.5,0.5,1.0}\epicNumbers,
...,
}
```

Since you are creating the super/subscripts using math mode, you need to change the math sizes. This is [accomplished through the `\DeclareMathSizes{}{}{}{}` command](https://tex.stackexchange.com/questions/8434/how-to-scale-math-font-only). In the example below I changed script size to 3pts and scriptscript size to 2pts.
(As an aside, since you didn't specify a fancy font, we are using Computer Modern, which doesn't allow arbitrary scalings; to fix that we load [`fix-cm`](https://ctan.org/pkg/fix-cm?lang=en).)

With that you also need a `\nobreak` to ensure the subsequent content stays with the "heading."

https://tex.stackexchange.com/questions/687863 | 1 | Is there a way to extend a `\vline` slightly beyond the boundary of the surrounding box? In the case I have in mind, I'm attempting to have a continuous vertical line between several items in an `enumerate` environment. This is what I've got going so far:
```
\begin{enumerate}
\item
\begin{enumerate}
\item[] \parbox{0.47\linewidth}{\textbf{Version 1}}
\hfill\vline\hfill
\parbox{0.47\linewidth}{\textbf{Version 2}}
\item \parbox[t]{0.47\linewidth}{Text that may cross to \\ a second line}
\hfill\vline\hfill
\parbox[t]{0.47\linewidth}{Text that may cross to \\ a second line}
\end{enumerate}
\end{enumerate}
```
This works well for lining up the vertical lines, but naturally there's a small gap between each line. I know I could use `\rule`, but then I'd have to manually set the height for every single item since they sometimes cover more than one line.
I'm open to other general solutions for the vertical line, but I'd like to use `enumerate` still because items will sometimes be cross-referenced elsewhere in the text and I'd like those to work as hyperlinks. For example, I know this would be easy to do using `tabular`, but then I'd either lose cross-referencing or have to jump through some hoops to make it happen.
| https://tex.stackexchange.com/users/154038 | Extend vline slightly beyond surrounding box? | true | **UPDATE** after comment.
This example uses `tikz` and the `tikzmark` library to draw a continuous vertical line.
*(You don't need to understand tikz code)*
The command
`\DrawVerticalRule[<color of the line>]{<name of the top mark>}{<name of the bottom mark>}`
(color is optional, default = black) will draw the vertical line between two tikzmarks.
Before using `\DrawVerticalRule`, you must manually
add the two `\tikzmark{<unique name>}`, before the beginning of each sentence. In the case of the bottom mark, it must be inserted after the last `\\`, with no white-space before the first word of the line.
Notice that `\hfill` was added between the parboxes to add some space between them, and prevent the vertical line from touching the end of a long sentence.
The line will have an x-offset of `1ex` to the left and will extend above or below each first letter by 1pt. The chosen line width is 0.8pt.

https://tex.stackexchange.com/questions/123758 | 10 | This is a question that arose in the comments here: [Change Section titles to Small Caps only in ToC](https://tex.stackexchange.com/questions/123549/change-section-titles-to-small-caps-only-in-toc/123551?noredirect=1#comment277105_123551)
I normally hide footnotes from the TOC by doing this:
`\section[title]{title\footnote{This is a footnote.}}`.
This works in a lot of document classes (memoir, article, ...), but not in all of them. `amsbook`, for example, uses the optional argument only for the running heads so the footnote mark still ends up in the TOC. So what is the 'universal solution'?
| https://tex.stackexchange.com/users/32655 | How to hide a footnote in a section title from the table of contents | false | Several updates have occurred since the above answer and there is now a "Universal" solution which works with most packages (This works with the following:
```
\documentclass[a4paper,12pt]{book}
\usepackage[T1]{fontenc}
\usepackage{titlesec}
```
Use `\chapter[TOC_Title]{Title in chapter\protect\footnote{This is a footnote that will only appear in chapter.}}`

https://tex.stackexchange.com/questions/687780 | 0 | By default, TeX inserts a strut in lines with a height and depth of `0.7\baselineskip` and `0.3\baselineskip` respectively. These are the minimum height and depth of the lines.
My question: Is there any way to modify these default settings for the `\strut` in lines? Let's say that I want to make the minimum height of each line equal to `\f@baselineskp` (the current height of the single line space) and to have a minimum depth of 0. I am not sure if this is good typography; I'm just looking into testing it out.
I've tried to change the default `\strut` height and depth without success. See my MWE:
```
\documentclass{article}
\makeatletter
%Attempt 1: I attempt to redefine \set@fontsize from the latex2e kernel. This fails to compile.
%\def\set@fontsize#1#2#3{%
% \@defaultunits\@tempdimb#2pt\relax\@nnil

% \@defaultunits\@tempskipa#3pt\relax\@nnil

% \fi
% \@font@info{Changing size to \f@size/\reserved@a

%
%Attempt 2: Doesn't work for some reason.

\Blinddocument
\end{document}
```
EDIT: I will leave this question up in case someone finds it helpful. I looked through `source2e.pdf`, particularly `ltpara.dtx`, and figured out the following solution:
Just add a strut at the start of each paragraph to ensure that it has a minimum height. For example, `\AddToHook{para/begin}{\rule{\z@}{\f@baselineskip}}` sets a minimal height equal to the current line height and`\AddToHook{para/begin}{\rule{\z@}{\f@size\p@}}` sets a minimal height equal to the current font size.
| https://tex.stackexchange.com/users/278534 | How to change the default strut parameters? | true | I've answered my question by adding a strut at the beginning of every paragraph via hooks.
This ensures that each line has a minimum height. For example, `\AddToHook{para/begin}{\rule{\z@}{\f@baselineskip}}` sets a minimal height equal to the current line height and `\AddToHook{para/begin}{\rule{\z@}{\f@size\p@}}` sets a minimal height equal to the current font size. If the paragraph touches the top of page, change the value of `\topskip` to ensure that that line has the same minimum height as the other lines.

I am just very curious about this, I only know how to type up basic mathematics.
