| https://tex.stackexchange.com/users/301368 | How I can set angle between edge in given code? | false | What you probably want is the following (but I am not sure which angle you actually want to change, maybe you can add some more information to your question about this):
```
\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[

\end{tikzpicture}
\end{document}
```
The `edge from parent` part should be placed after defining the `child`ren, especially if you add nodes that are to be placed on the edges (see [the manual](https://tikz.dev/tikz-trees#sec-21.6) for another example). For nicer positioning, I would remove the `right` or `left` option from the nodes that are placed on the edges.
To change the angle in such a basic tree (that is, a Ti*k*Z tree that does not use any additional library), you can change the angle of the edges using the `sibling distance` and/or `level distance` options that you can not only add to the whole tree, but also to specific `child`ren. For example:
```
\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[
sibling distance=25em,
every node/.style={
shape=rectangle,
rounded corners,

https://tex.stackexchange.com/questions/692035 | 0 | I've been trying to count a particular character within a string (an argument of a new environment I've defined). I came across [this](https://tex.stackexchange.com/q/336294/96582) question, where one of the [answers](https://tex.stackexchange.com/a/525246/96582) pointed me in the right direction. While I was able to adapt the suggested approach to my needs, a new problem arose: `Missing number, treated as zero. <read again> \xparse function is not expandable`.
To make the suggested code initially work, I had to assign the argument of my new environment to a macro like this `\def\labelvalue{#1}\def\coloncount{\countin*{:}{\labelvalue}}`.
Printing the result works fine and gives the correct result, but unfortunately the above error is thrown when I try to compare the result to an integer, e.g. `\ifnum \coloncount=1`. I found [this](https://topanswers.xyz/tex?q=2020) on the web, which links to the answer I was following, but I didn't get their suggestion to work.
The aim is to define an environment that outputs different texts depending on the label passed. Since the labels are all structured according to the same scheme (rq:x or rq:x:y), it is to be decided which output is to take place depending on the number of colons.
The document is compiled with latexmk and the most recent version of all packages used.

```
I've moved the code that was originally in the main body of the `luacode` environment to a function `M.process`. The `M` table is returned from this library, so it will enable you to use this code in this way:
```
local bibr = require "bibr"
bibr.process("xml code...")
```
I've also made another function, `M.process_file`, which will transform XML file, so you don't need to pass the XML code to your document.
You then need a LaTeX package that will provide commands that can be used in your documents. It can look like this, `bibr.sty`:
```
\ProvidesPackage{bibr}
\NewDocumentEnvironment{processbibr}{+b}{%
\directlua{
local bibr = require "bibr"
bibr.process([[\unexpanded{#1}]])
}
}{}
\NewDocumentCommand\processbibrfile{m}{%
\directlua{%
local bibr = require "bibr"
bibr.process_file("#1")
}
}
\endinput
```
It provides `processbibr` environment and `\processbibrfile` command. The environment can be used if you want to put the XML code in the document, the command for including external XML files.
It can be used like this:
```

In general, I think it is better to use `\processbibrfile`, as you shouldn't run into strange errors that can happen when you include the XML file directly to your TeX file.

in his answer to one of my previous questions: <https://tex.stackexchange.com/a/691806/224317>. To make this code do everything I would like it to do, there needs to be a companion function called `\mapcodes` that maps standard codes like `"03B1` for a Greek alpha to the slot location in the specific font. The only essential difference is that it needs to include a third argument containing the font family and *probably* needs to accept a different type specifier in the first argument. A working version of that is provided by egreg here: <https://tex.stackexchange.com/a/691747/224317>. Now, for the tricky part and the gist of the question.
I would like both of these functions to be able to take single arguments as well as comma-separated lists where applicable. As long as the list is provided "inline", I think they will work as is. I know for a fact that
```
\mapcommands{\alphatwo,\beta}{"03B1,"03B2}
\mapcommands{\gamma}{"03B3}
```
causes no problem, for instance. I presume the second usage is treated as a list of length one. But I also would like to be able to create and name lists with commands of the form
```
\DeclareCommandList{GreekCommands}{\alpha,\beta,\gamma,\delta}
\DeclareCodeList{GreekCodes}{"03B1,"03B2,"03B3,"03B4}
```
analogous to `\defineblock` in egreg's answer and then pass them as follows:
```
\mapcommands{GreekCommands}{GreekCodes}
```
I have experimented, but being new to `expl3` and still a little rough in my understanding of the underlying TeX expansion mechanism, I have not yet achieved success. I am guessing there is either (a) a way to take a generalized argument and then determine its nature, doing something applicable with each case, or (b) a way to do something equivalent to function overloading. It *appears* that `expl3` may provide something like this with variants in the `l3expan` package, but I'm not sure. So while I would like to solve this specific problem, I would also like to understand the differences in these two calling mechanisms in general, how to deal with them, tips for troubleshooting, and so forth.
| https://tex.stackexchange.com/users/224317 | Is it possible to define commands that accept different argument types? | false | The following adds the two macros and support for them to your MWE.
The support is added by introducing two optional stars, if either star is given the next mandatory argument is considered as a named list input instead of a comma separated list.
We could also not require the stars, and instead check whether such a list exists, if you need help with that just leave a comment.

| https://tex.stackexchange.com/users/298086 | How can I set the length of the indentation in the novel document class? | false | `novel.cls` tries **really** hard to prevent you from playing around with various "text lengths" (which include `\parindent`). Two particular ways where this is done:
1. `novel.cls` calls `\gsetlength\parindent{1.5em}` inside an `\AtEndPreamble` (in fact all textlengths are set there); so any changes to `\parindent` in the preamble will be overwritten.
2. `novel.cls` **restores** `\parindent` to the default value at every `\end{ChapterStart}`.
If you **really** want to change the default value, you will need to provide the new `\parindent` *after* `\begin{document}` and also bypass the restoration, by setting the length `\normalparindent`. So, try inserting immediately after `\begin{document}`

https://tex.stackexchange.com/questions/692037 | 0 | Is there an easy way to draw complex images in LaTeX? By this I mean: Have a look at the [following question](https://tex.stackexchange.com/questions/348/how-to-draw-a-torus).
Some answers provide incredible pictures, very elaborated. In the (rudimentary) way I can create figures with tikz or pstricks, it would be impossible for me to come up with the correspondings codes. This made me think: Perhaps there are some tools that help write down the code.
I am aware of things like [tikzcd-editor](https://tikzcd.yichuanshen.de/) or [LaTeXDraw](https://latexdraw.sourceforge.net/). I also know about [InKscape](https://inkscape.org/), although I have never used it myself.
Howerver, none of them seem to be appropriate to draw tori or spheres. Yes, with LaTeXDraw one can draw ellipses and create things that resemble those surfaces, but the quality of these draws is as good as the quality of Paint.
I am thinking more of some type of image recognition software that identifies the geometric object (as well as some text the figure might have) the user has drawn and produce the corresponding code. Does anything like that exist?
| https://tex.stackexchange.com/users/122188 | how to get hand draws into code | true | There are essentially two parts to your question:
1. You need to complete a computer vision task to interpret what user-defined sketches ought to be. There has been some progress in that front, a publicly accessible service in this direction is [Google's autodraw](https://experiments.withgoogle.com/autodraw), but that only really works for 2D sketches. I can imagine 3D being somewhat harder because you are trying to interpret a 3D image from a 2D projection.
2. You also then need an AI assistant to generate code based on the computer vision interpretation. This is allegedly one of the things that ChatGPT and other LLMs can do. So let's give it a try.
Below the cut is the ChatGPT response to the prompt: "How do I draw a torus in TikZ".
(For the curious, no, the code included does not build. To start it is missing `\usepackage{tikz-3dplot}`; and there are several other mistakes. Though not being a TikZ expert I cannot really decide how serious these issues are.)
Using this as an illustration of status-quo, my guess would be that such a tool as you are looking for *does not yet exist*.
---
Drawing a torus in TikZ involves a series of steps to define the 3D shape and then projecting it onto a 2D plane. Here's a step-by-step guide to drawing a torus using TikZ:
Step 1: Load the necessary TikZ libraries
To draw 3D shapes, we need to load the `tikz` package with the `3d` and `calc` libraries.
Step 2: Define the torus parameters
Decide on the major radius (distance from the center of the torus to the center of the tube) and the minor radius (radius of the tube).
Step 3: Calculate the torus points
Calculate the coordinates of the points that form the torus based on its parameters.
Step 4: Draw the torus surface
Using loops, connect the calculated points to form the surface of the torus.
Step 5: Optional - Add shading and coloring
You can add shading and color to enhance the appearance of the torus.
Here's the TikZ code to draw a torus:
```
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{3d, calc}
\begin{document}
\begin{tikzpicture}[scale=1.5, tdplot_main_coords]
% Torus Parameters
\def\R{2} % Major radius (distance from center to center of the tube)
\def\r{0.7} % Minor radius (radius of the tube)
% Calculate the torus points
\pgfmathsetmacro{\StepSize}{5}
\foreach \i in {0,\StepSize,...,360}
{
\foreach \j in {0,\StepSize,...,360}
{
\pgfmathsetmacro{\x}{(\R + \r * cos(\j)) * cos(\i)}
\pgfmathsetmacro{\y}{(\R + \r * cos(\j)) * sin(\i)}
\pgfmathsetmacro{\z}{\r * sin(\j)}
\coordinate (P) at (\x,\y,\z);
\draw[fill=gray!50] (P) circle (0.05); % Optional: Draw points to check the torus points
}
}
% Draw the torus surface
\foreach \i in {0,...,72}
{
\foreach \j in {0,...,72}
{
\pgfmathtruncatemacro{\nexti}{mod(\i+1,73)}
\pgfmathtruncatemacro{\nextj}{mod(\j+1,73)}
\draw[thick, fill=blue!30] ($ (P\i\j)!0.5!(P\nexti\j) $) --
($ (P\nexti\j)!0.5!(P\nexti\nextj) $) --
($ (P\nexti\nextj)!0.5!(P\i\nextj) $) --
($ (P\i\nextj)!0.5!(P\i\j) $) -- cycle;
}
}
% Optional: Draw the torus center and axes
\coordinate (Center) at (0,0,0);
\draw[thick,-latex] (Center) -- (3,0,0) node[anchor=north east]{$x$};
\draw[thick,-latex] (Center) -- (0,3,0) node[anchor=north west]{$y$};
\draw[thick,-latex] (Center) -- (0,0,3) node[anchor=south]{$z$};
\draw[fill=red] (Center) circle (0.05); % Torus center point
\end{tikzpicture}
\end{document}
```
This code will create a 3D visualization of a torus. The `\R` and `\r` values can be adjusted to change the size of the torus. The resulting TikZ picture will be a 3D representation, and you can view it from different angles by rotating it in your PDF viewer.
Remember to compile the document using a LaTeX compiler like `pdflatex`, and you should obtain the output containing the TikZ drawing of the torus.

https://tex.stackexchange.com/questions/359257 | 3 | I use `autonum` package to number the equations only when they are referenced. However, sometimes I want to refer to a range of equations. For example, I have 4 equations and I type `\eqref{eq1}-\eqref{eq4}`. But, the 2 equations in between will not be numbered, since they are not referenced. Is there some way to manually number these equations as well?
Here is a minimal example
```

https://tex.stackexchange.com/questions/118010 | 6 | The `braket` package defines Dirac's braket notation. To use it in Lyx, I add the line:
```
\usepackage{braket}
```
to the LaTeX preamble. Then Lyx will be able to compile commands like `\bra` and `\ket`. Problem is that the Lyx editor itself won't recognize this commands.
If instead of using the `braket` package I had defined math-macros for the commands `\bra`, `\ket`, etc., I could tell Lyx how these things should look in the editor. That is, I can tell it to put an `\rangle` before the argument (that Lyx knows how to draw) and a `|` after.
Is there a way to use the `\bra`, `\ket`, etc., commands from the `braket` package, and still be able to tell Lyx how these should look in the editor?
EDIT: Right after posting, I discovered [this](https://tex.stackexchange.com/q/80002/19017) question, which mentions the Instant Preview feature of Lyx. Although this kind of fixes my issue, it's not exactly what I want. I want to be able to specify what the command should look like in the editor, in terms of other commands that Lyx already recognizes (in the editor), like I would do with a math-macro.
| https://tex.stackexchange.com/users/19017 | Using braket package with Lyx with WYSIWYG | false | This inconvenience is finally solved in From LyX-2.4.0-beta3 (format 616). You can just fill the LyX box to define how the macro displays in LyX and leave the TeX box empty, and things will work as expected.
As written in the LyX source code:
```
* Format incremented to 616: Do not output LaTeX for a macro if the LaTeX part is empty
- This allows the user to define the LyX display for LaTeX commands
that are already defined (e.g., in user preamble or a package).

Is this legally ok?
| https://tex.stackexchange.com/users/23436 | Classes (.cls) copyright | true | There is no single answer to this question, and legal questions are not answerable here generally, since they depend on particular jurisdictions etc.,
That being said, many classes and packages are released under licences that allow reuse and modification. But you need to check the licence conditions themselves. As a rule of thumb, if the class or package is released under the LPPL licence, then you are free to develop a derived package or class using that code. If a class or package has no licensing information at all, then it's likely that you have no rights to create a modified class or package from that code.
Copyright is a separate issue: most code is copyrighted by the original author(s) and that copyright doesn't disappear just because the code has an open source licence, so when you produce a modified work, you can't just take the code and call it your own. Therefore you should preserve original copyright notices in modified versions of code you modify. You do, however, own the copyright to the modifications you make.

However, as mentioned in the comment by egreg, the math symbols may output some strange Chinese characters in the bookmark. I wonder what cause this and how to avoid this issue?
| https://tex.stackexchange.com/users/54169 | \detokenize in bookmark create strange characters | false | Basically you can't avoid it. `\detokenize` is not a good idea. If you use a catcode 12 backslash in the title, may it be with `\detokenize` or `\string\` or something else, you will break the bookmarks. You get something like `\000\040\alp \000h\000a` and that is simply rubbish.
I see no easy way to change this. At the place where a substitution could be done, hyperref has already replaced some commands by the internal representation which uses catcode 12 backslash too, and so no simple substitution is possible as it would break other commands like `\textbackslash`. One would need a regex and that would slow down the compilation quite a lot for a very small gain.
What you naturally can do, is to pass the content of the math to the `\fake@math` command, and to predefine the set of symbols you use to do something sensible:
```

https://tex.stackexchange.com/questions/692016 | 4 | I have been a LaTeX user for about two decades now, with a basic knowledge of the internal mechanisms and quirks of TeX. If at the beginning of my learning curve things didn’t appear too complicated, now I feel overwhelmed by the TeX world, especially when trying to bridge TeX with the “outside” world and with the new technologies: modern fonts and encodings, “modern” PDFs and document formats that go beyond the usual “paper” document, combining TeX with modern scripting languages, drawing and beyond, interactions with the web, e-books, online collaboration, … and this is just that comes through my mind right now.
I know that there many users on tex.stackexchange.com that have a wide view over the current TeX world and a more comprehensive understanding about what goes “under the hood”, so that is why I would like ask you for a “*survival guide through the modern jungle of TeX*”: how would you guide someone lost?
If you were to make a guide for the modern TeX world, what would you include in there, what would be the steps that someone like me would have to take in order to get a clearer understanding of the picture, to navigate and explore in all directions and not get lost along the way?
I know that what I'm asking is not too precise, but feel free to contribute anything that you believe is most relevant, from your own perspective and experience.
| https://tex.stackexchange.com/users/10635 | A guide through the modern jungle of TeX | false | This is a partial answer to your question, as it only sees to the internal
workings of (plain) LuaTeX. Other answers may give an overview of the current
state of LaTeX.
### Manuals
There is no single manual for modern TeX. Instead, you will have to consult the following in chronological order:
* For the original (core) TeX, either the TeXBook or [Tex by Topic](https://ctan.org/pkg/texbytopic).
* For the [eTeX](https://ctan.org/pkg/etex) extenstions, the [eTeX manual](https://ctan.org/pkg/etex) and the file `etex.src`.
* For the pdf backend, the [pdfTeX reference manual](https://ctan.org/pkg/pdftex) and the [PDF specification](https://pdfa.org/resource/iso-32000-pdf/).
* For LuaTeX, the [LuaTeX reference manual](https://ctan.org/pkg/luatex), together with the [`ltluatex`](https://ctan.org/pkg/luatexbase) and [`luaotfload`](https://ctan.org/pkg/luaotfload) support packages, as well as the file `luatex.ini` from which the plain LuaTeX format is generated.
Every manual on this list expands on (and assumes you know) the previous one.
For a concise diachronous overview of control sequences, you might like [this
document[pdf]](https://petr.olsak.net/ftp/olsak/optex/tex-nutshell.pdf) by Petr Olšák.
### Outdated parts
In the above (and here on SE) you should ignore anything that talks about:
* The `dvi` format or PostScript (`ps` and `eps`): use PDF instead.
* Fonts in the `tfm` format: use TrueType (`ttf`) or OpenType (`otf`)
fonts instead.
* Text encodings: just use unicode (utf-8) and a modern font.
### Vector graphics
The popular [`tikz`](https://www.ctan.org/pkg/pgf) can make use of all modern PDF features. Consider using [`pgfplots`](https://www.ctan.org/pkg/pgfplots) for plots and diagrams.
To these, LuaTeX adds the option of using MetaPost directly. For doing so, you have the choice between [`luamplib`](https://www.ctan.org/pkg/luamplib) and [`minim-mp`](https://www.ctan.org/pkg/minim-mp). Their feature sets are not identical, so the choice will have to depend on the specifics of your use-case. The latter can also be used as a stand-alone MetaPost compiler.
### Mathematical typesetting
This part is especially fragmented. Plain TeX has at least three counterparts to LaTeX’s `unicode-math`:
* The luatex-plain format that comes with the ConTeXt distribution contains quick-and-dirty support for unicode mathematics (in the file `luatex-math.tex`) that *might* be good enough for your needs.
* The [OpTeX extended plain format](https://petr.olsak.net/optex/) includes a more comprehensive approach baked-in (but then you will have to use the rest of OpTeX, too); it comes with a [summary of mathematical typesetting[pdf]](https://petr.olsak.net/ftp/olsak/optex/optex-math.pdf) that is worth reading even if you will never use OpTeX.
* Otherwise, the [`minim-math`](https://www.ctan.org/pkg/minim-math) package provides comprehensive and
format-agnostic mathematics support.
### PDF features
* For hyperlinks and bookmarks, see either [`navigator`](https://www.ctan.org/pkg/navigator) or [`minim-pdf`](https://www.ctan.org/pkg/minim-pdf).
* For generating tagged PDF and PDF/A, see [`minim-pdf`](https://www.ctan.org/pkg/minim-pdf).
* For XMP inclusion, see [`minim-xmp`](https://www.ctan.org/pkg/minim-xmp).

https://tex.stackexchange.com/questions/688346 | 0 | I am somewhat new to LyX, and while I've been using it for long enough to know my way around it, there is one feature about it that is becoming ever more irritating; as a student, I mainly use it for writing math courses and need to do so as fast as possible to keep up with the pace. The crux of the problem is that, as you know, TeX code in the math editor is triggered by the \ character. Unfortunately, I happen to have being French as a hobby, and consequently my keyboard layout is the standard French one. Turns out, whoever chose \ as the standard character for writing code very much did NOT have french people in mind, as its position on French keyboards is absolutely atrocious. Should you want to know, it is written by the combination AltGr + 8 (Alt Gr being a key just to the right of the spacebar, in case your keyboard doesn't feature it). That is to say, to type every single TeX command, I have to stretch out my right hand as much as possible, while blocking my thumb under the center of my palm. It's awkward, it makes me lose absurd amounts of time, and brings me physical pain due to carpal tunnel syndrom; in short, I hate it with a burning passion (try it, you'll see what I mean).
Which is why I would like to know if there is a way to type \ with some shortcut of my choice, and still have LyX behave as if I typed it as usual. I have tried modifying my .bind files to achieve that, but to no avail; it seems that, while it would be very easy to do with any other character, the unique status of \ (including in .bind files) won't let me do it.
`\bind "<My-Shortcut>" "insert-unicode 0x005C"` gave me hope for a few seconds, as it does type \ in text mode, but sadly, it doesn't do anything in math mode.
`\bind "<My-Shortcut>" "math-insert \\\"` prints [\"] in math mode for some reason, which is progress, but not really interesting because of the double quotes (I'm not sure where those come from). The same instruction, with any other number of backslashes, or with 3 but without the final double quotes, only creates an empty math editor box.
Lastly, I would like to mention that changing the language of my keyboard (with Shift+Alt for example) is not really a valid option; admittedly, \ is very conveniently placed on english keyboards, but 1- I would still be writing in French, so I need to have access to accents and 2- my actual, physical keyboard would still be in French, so I would have to memorize the entire english layout which doesn't sound like I'd be saving time.
This being the situation, do you know of any way to achieve that? Thank you very much for your help in advance!

Simple question. I want to use LaTeX with Inkscape on mac. I already use a tex editor so I should have most of the LaTeX stuff I need. However when I go to "Extensions>Render>", there's not a LaTeX option there as other online sources suggest.
As a fudge I tried using the application Latexit to generate SVG/EPS images to import but I can't seem to get import of those to work either.
| https://tex.stackexchange.com/users/82643 | How to use LaTeX with Inkscape (MAC OS X) | false | I just tested to run the following code in **terminal** on **Mac OS Ventura** using **inkscape version 1.3**.
```
open -a /Applications/inkscape.app/
```
The LaTeX rendering and function plot rendering all worked as intended.
If you use inkscape frequently, you can save time by creating the **alias** for the command above in **terminal**.
---
**Step 1:** Determine which shell you are using. Common ones are `bash` and `zsh`. You can check by running:
```
echo $SHELL
```
---
**Step 2:** Open appropriate shell configuration.
For `bash`, enter `nano ~/.bashrc`.
For `zsh`, enter `nano ~/.zshrc`.
---
**Step 3:** Create the alias.
```
alias inkscape="open -a /Applications/inkscape.app"
```
To save the alias, you can press **Ctrl + X**, then **Y** to save the changes.
---
**Step 4:** To apply the changes to your current terminal session, run the following command.
For `bash`, `source ~/.bashrc`.
For `zsh`, `source ~/.zshrc`.
---
Finally, you can open the inkscape with `pdflatex` and function plotting functioning well in **terminal** by just type the key word alias `inkscape` to open the inkscape application.

But the main point is to understand the search order: The code will at first use `kpsewhich` to search for the image and only if this fail check the pathes given by `\graphicspath`. That means that pictures in the current folder and in the texmf tree are found first and so preferred.

However, I want my students to still know that it is a line integral, so I would like to keep the "C" in addition to the limits of integration. The problem is that I cannot find a way to do so. I have tried experimenting with `\limits` but that does not work either. Here are some of my attempts:
`\int_C \limits_{a}^{b}` (I really thought this one was going to work.)

A line integral over the curve *C* *can* be computed as an ordinary integral once you know a parameterization of the curve; but in the latter integral there's no remaining explicit trace of the curve *C*.
Anyway, this should do what you want. Note the name I gave to the command.

Somehow the color `cell{1}{1} = {\Tcolor},` breaks. Why?
`cell{1}{1} = {green},` works...
EDIT: I guess in my attempt to create a MWE I shortened it too much. There is a need for a function instead of a simple color:
```

| https://tex.stackexchange.com/users/281557 | Why does tabularray not accept colors from commands? | true | The `cell{<i>}{<j>}` key can accept several types of values; for instance, according to the manual, you can do
```
cell{1}{1}={cmd=\fbox}
```
Thus the managing of values is necessarily complex. When a value is just a string that's not another key, it is interpreted as a color name for the background.
You can use `bg=<color>` and, in this case, you can use a macro.

https://tex.stackexchange.com/questions/692095 | 1 | I have a LaTeX-Project that is split into multiple files using the package `subfiles`. The project has the following structure:
```
main.tex
.latexmkrc
lib/custom-class.cls
lib/custom-package.sty
foo/bar.tex
foo/image.png
baz/...
```
I use `latexmkrc` to include the class- and package-files in `lib` in `TEXINPUTS`:
```
ensure_path( 'TEXINPUTS', 'lib//' )
```
The project builds correctly when I build `main.tex`, but when I build one of the subfiles (e.g. `for/bar.tex`) I get the error
```
File `custom-class.cls` not found.
```
I realise this is because `.latexmkrc` is not used when building in a subdirectory. I found a [discussion](https://github.com/James-Yu/LaTeX-Workshop/issues/1895) on the GitHub-Page of the VSCode-extension LaTeX-Workshop (which I am using) and the best solution there seems to be to just copy and paste `.latexmkrc` into the subdirectories – the issue is that I have many (20 or so) subdirectories and I want to avoid having to change all these files whenever I change the main `.latexmkrc`, especially since I am not the only one working on this project. Is there any other way, or can I, perhaps, create a `.latexmkrc` in each of the subdirectories that just imports the main `.latexmkrc`?
Thanks for any pointers.
| https://tex.stackexchange.com/users/269090 | latexmkrc and subfiles | true | Try adding the following lines at the very beginning of the main file:
```
\makeatletter
\def\input@path{{lib/}{../lib/}}

If you are submitting to an AIP journal, you should use `revtex` which loads the correct bibtex file. AIP has [even published templates for Overleaf](https://publishing.aip.org/resources/researchers/author-instructions/#latex).
If you, for some reason, just want to use the AIP bibliography styles, the one that revtex loads is either `aipnum4-2.bst` or `aipnum4-1.bst` (depending whether you are basing it on `revtex4.1` or `revtex4.2`). Both can be found on CTAN.

The commands I just mentioned work with "simple" parameters. In a line of code, I've used the `%` symbol to highlight a problem; when I try to nest one of those commands with itself it throws an error. Could you help me figure out the problem?
| https://tex.stackexchange.com/users/301449 | Can I nest the \newcommand command with itself? | false | If it's not too late to change syntax, I advocate an optional argument for `\TCConjunto`

Sorry for `\emptyset`, but my eyes bleed when I see the plumber's symbol `\varnothing` used for the empty set.
With `\IfNoValueTF` we check whether the optional argument is present; with `\IfBlankTF` we check whether the supplied argument is empty (better, consists only of zero or more blank spaces).

https://tex.stackexchange.com/questions/687546 | 1 | How can I suppress the links to the last page on each page? Consider the following example:
```
\documentclass[colorlinks]{moderncv}
\usepackage{lipsum}
\name{}{}
\begin{document}
\lipsum
\end{document}
```
Here we have the page numbering 1/2 and 2/2, but the last 2 is marked red because it is a link. How can I suppress the behavior so that I have 1/2 and 2/2 only?
| https://tex.stackexchange.com/users/136549 | moderncv: suppress links to last page | false | You can simply add something like
```
\fancyfoot[r]{\color{color2}\pagenumberfont\strut\thepage/\pageref*{lastpage}}
```
after your `\begin{document}` line. The `*` after the `\pageref` will only print the page number, without a link.

https://tex.stackexchange.com/questions/437447 | 2 | I know about `\newcommand[<arg_num>]{#1 ... #n}` to define a simple macro with up to nine arguments. (More if you link multiple `newcommands` together)
I recently started to look at `xparse` for some additional features such as multiple optional arguments, as well as `keyval` -- which works as I want it to, as long as each option is just one keyword.
What I would ultimately like to have is a way to address certain options by name and assign values and strings like so:
```
\MyCommand[
opt1="this is val1",
opt4="this is val4",
optN="this is valN"
]{argument1}
```
Or maybe even:
```
\MyCommand{
arg1="this is val1",
arg4="this is val4",
argN="this is valN"
}
```
(I know that `"this is val"` is not LaTeX syntax, maybe `{this is val}`?)
I am still fairly new to LaTeX, and I am not sure how to properly search for this. So I hope someone here can point me in the right direction.

| https://tex.stackexchange.com/users/228936 | TikZ coordinate | false | Your first point (`bullet`) is inside a `node` for which you didn't define any size or shape, so it's adjusted to its content (the bullet) and has the default rectangular shape.

See the code below (with a larger `inner sep` to help you visualize it).

| https://tex.stackexchange.com/users/210048 | How do \left | and \right | actually work? | false | For Latin Modern, one can look at the vertical line `U+007C`. Screenshot from FontForge:
Here we can see, that there is the base glyph and then no less than seven variants (`divides.v1`, `divides.v2` and so on, up to `divides.v7`). If one needs larger, there will be a larger, extensible one built with one `divides.bt` at the bottom, one `divides.tp` at the top, and as many `divides.ex` as needed. The recipe on how to glue them together is given there as well, look at the numbers.
Other fonts might (will, likely) have a different number of variants, and some might lack an extensible recipe. No guarantees.

Although it's an imperfect proxy of LaTeX usage, we can estimate the relative growth of LaTeX along with the growth of the number of Overleaf users:
* **2019 March 27:** [4 million users](https://www.overleaf.com/blog/wow-four-million-people-now-use-overleaf)
* **2019 November 28:** [5 million users](https://www.overleaf.com/blog/celebrating-over-five-million-users-and-a-quarter-million-daily-actives)
* **2020 July 1:** [6 million users](https://www.overleaf.com/blog/reaching-six-million-users-in-an-unprecedented-six-months)
* **2021 July 1:** [8 million users](https://www.overleaf.com/blog/eight-million-users)
* **2021 December 21**: [9 million users](https://www.overleaf.com/blog/nine-years-nine-million-users)
* **2022 June 8**: [10 million users](https://www.overleaf.com/blog/wow-ten-million-users)
* **2022 November 23**: [11 million users](https://www.overleaf.com/blog/starting-a-new-era-with-11-million-users-and-100-million-projects)
So, Overleaf grows by roughly 2 million users per year, which has a certain sense to it—after all, every year, newly matriculated undergrads and grad students are introduced to LaTeX for the first time, and therefore create new accounts at a more or less constant rate.

There are [**28 TeX user groups**](https://www.ntg.nl/lug/) spread across the world, and Overleaf users account for at least [**189 different countries**](https://www.overleaf.com/blog/wow-ten-million-users).

[Similarweb](https://www.similarweb.com/website/tex.stackexchange.com/#geography) gives **23%** of all TeX StackExchange visits as from the **United States**, followed by **8% from Germany** and **6.6% from India**, although there's probably some selection bias because this is an English-speaking site.
Overall, it's pretty safe to say that LaTeX is used globally, although I'd still imagine usage is more skewed towards Anglophone communities, given that macro names, error messages, documentation, the *TeXbook*, etc. are all in English.

If so, the key is on p. 18 of the manual "B. Per-Gate Styling". To demonstrate I put the n in red, and shifted it along the x-direction. This package requires some "encapsulation" of tikz-formatting-options: the kind of syntax you'd use when defining own styles etc.

https://tex.stackexchange.com/questions/692222 | 1 | I have the challenge of needing to start a *clean page* in a *two-column* (Xe)LaTeX document, yet *without the fush* semantics of `\clearpage`.
Consider the following example, which is the closest I got to achieving the desired output:
```
\afterpage
{
\clearpage
\begin{tikzpicture}[remember picture,overlay,x=\paperwidth,y=\paperheight]%
...
\end{tikzpicture}
\clearpage
}
```
This waits until the current page has ended, and then fills in a `tikzpicture`, such that I can draw on an empty following page. After this drawing, the regular document resumes - just like pasting a picture page into the regular document.
However, the following problems exist:
* Due to the `\clearpage`, the above code forces all prior floats to be flushed. This is actually undesired since I have plenty of floats and I don't want the tikzpicture to interfere with the placement. I would like to **avoid the flushing**.
* If I replace `\clearpage` with `\newpage`, I can avoid the flushing but this approach is unsuitable for a two-column document, since there `\newpage` changes its meaning to starting a new column.
* If I replace `\clearpage` with `\newpage~\newpage` I must always make sure to only trigger it after even columns.
* If I *remove* the first `\clearpage`, the `tikzpicture` actually does start on a new page as desired; however, the subsequent document content is placed below the `tikzpicture`.
I assume that two different solution approaches may be possible but I did not manage to succeed with either one:
* Find a two-column `\clearpage` without flush
* Use `\afterpage{\tikz{...}\magic\newpage~\newpage}` where `\magic` assures that no other content appears on the page.
Any suggestions or thoughts would be most appreciated.
| https://tex.stackexchange.com/users/301493 | Start a new page in two-column mode without \clearpage | false | The `\null` is because you can't have two `\newpage`s (or `\newcolumn`s) in a row.

I'd like to point out LaTeX has plenty of math environments including their inner variants, which you can nest, which let you format and organise very complex expressions. It's all explained in the documentation of the package [amsmath](https://www.ctan.org/pkg/amsmath). I would also recommend reading documentation of [mathtools](https://www.ctan.org/pkg/mathtools), which loads [amsmath](https://www.ctan.org/pkg/amsmath) and adds many improvements and additional solutions.

I was wonder is it possible to make the latexmk ouput more better like the error message with a red color and the warning message with the yellow color or other way to make it more easy to figure out where is going wrong. is there any improment way to make it possible?
| https://tex.stackexchange.com/users/69600 | is it possible to make latexmk ouput with color | false | Yes, it is possible but you will have to modify your `latexmkrc` or use an independent program to pipe the output through. The example is explained [in this blog post](https://blog.mje.nz/2019-07-23-coloured-latexmk-output/), you have two options:
1. modifying latexmkrc
2. Using bespoke solution in Python or similar to cooler outputs
latexmkrc
=========
```
{
no warnings 'redefine';
use Term::ANSIColor;
my $old_warn_running = \&main::warn_running;
sub color_warn_running {
print STDERR color('green');
$old_warn_running->(@_);
print STDERR color('reset');
}
if (-t STDERR) {
# Only use color if a terminal is attached
*main::warn_running = \&color_warn_running;
}
}
```
Python-based solution
=====================
```
#!/usr/bin/env python3
"""Filter output of pdflatex.
Usage: filter.py <latex engine> <options> <file>
"""
import os
import subprocess
import sys
import colorama
from colorama import Fore, Style
colorama.init()
def main(cmd):
# Disable pdflatex line wrap (where possible)
env = dict(os.environ, max_print_line="1000000000")
# Run pdflatex and filter/colour output
pdflatex = subprocess.Popen(

for line in iter(pdflatex.stdout.readline, b''):
line = line.decode('utf8').strip()
if line.startswith('(/') or line.startswith('(./'):
# Start loading file
pass
elif line.startswith(')'):
# Finish loading file
pass
elif line.startswith('!'):
# Error
print(Fore.RED + line + Style.RESET_ALL)
elif line.startswith('Overfull') or \
line.startswith('Underfull') or \
'warning' in line.lower() or \
'missing' in line.lower() or \
'undefined' in line.lower():
# Warning
print(Fore.YELLOW + line + Style.RESET_ALL)
else:
print(line)
if __name__ == '__main__':

You would then add `$pdflatex = "./filter.py pdflatex %O %S";` to your `latexmkrc`.

The C57BL/6J mouse was placed in the center of this arena, facing the SIZ, and could freely explore the chamber. After 2.5 min, the mouse was removed, and an unfamiliar CD1 mouse was placed in the cage. During this second trial, the C57BL/6J mouse’s reaction to the CD1 mouse was registered. Locomotion and time spent in the SIZ were recorded. The immobility time within the SIZ (indicating potential freezing behavior) was registered to adjust the C57BL/6J mouse’s time interacted with the CD1 mouse.

https://tex.stackexchange.com/questions/692277 | 13 | I have a personal dislike of the CM typewriter italic design. (Sorry,
DEK :). It's fine for what it is, but I just find it distractingly fancy.) For TUGboat, I always want to replace it with typewriter slanted.
My question is, is there a way to do such a fundamental substitution at
the LaTeX level? (I don't want to distribute different
.fd files for TUGboat. That would be much too error-prone for authors, aside from
being generally crazy. :)
Trivial example:
```
\documentclass{article}
\begin{document}
\textit{\texttt{Italic typewriter that I want to be slanted.}}
\end{document}
```
For this tiny case, it's obviously no problem to replace \textit with
\textsl in the TeX source. But in practice there are plenty of times
when it is not so simple, because the \textit, or \emph, or whatever, is buried inside macros, the result of running BibTeX or other subprograms, etc.
Many packages (e.g., listings) have their own configuration methods that can suffice. I just wondered if there was a way to do it globally. It would save me a lot of time and effort. --thanks, karl.

https://tex.stackexchange.com/questions/504558 | 7 | I have a macro to draw rather complicated diagrams in tikz which makes use of pgfkeys in order to be as flexible as possible on arrows, labels and their styles. I allow all the commands of the library *cd*. What I would need is a parameter/option, such as `Rrightarrow` of the *ams* package, that I can pass as pgfkey which could draw triple (or even quadruple) arrows, precisely like I can pass the parameters `leftarrow`, `Rightarrow`, `equal`, `squiggly`, ...
The following topics [Triple lines in tikz](https://tex.stackexchange.com/questions/38431/triple-lines-in-tikz) and [Costum arrow shaft in tikz](https://tex.stackexchange.com/questions/230098/custom-arrow-shaft-in-tikz) contain some beautiful code going in that direction, but I am not able to squeeze them into a tikz-cd arrow-style option. I think I understand the code of the (second answer of the) second link, where in order to provide a 3-arrow or a 4-arrow, two different arrows are overlapped. Since the arrows of my macro are fixed, I cannot use this solution. I think the code of the first link could be used to provide a satisfying solution but: I don't know a lot of tikz yet (I have always used tikzcd), in the comments there they seem to imply that adding a arrow tip to a triple line is hard. I tried to play a bit with the code, modifying what I think should be chanced, but I haven't managed to produce anything concrete.
| https://tex.stackexchange.com/users/25158 | Triple arrows in tikz and tikz-cd | false | There is now a beautiful package, [tikz-nfold](https://ctan.org/pkg/tikz-nfold) by Jonathan Schulz, providing a simple solution to this problem. You can specify the TikZ arrow style `scaling nfold=3` (or simply `nfold=3` if you want a fixed arrow width) to draw a triple arrow, and similarly for higher arrows.
In my experience, this produces more aesthetically pleasing arrows than other solutions, and is compatible with the various other TikZ styles that are common in commutative diagrams.
Example:
```
\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{nfold}
\begin{document}
\begin{tikzcd}
A \arrow[r, Rightarrow, scaling nfold=3] & B \\
C \arrow[r, Rightarrow, nfold=3] & D

In tikz you can easily draw double-arrows, which is about the same as using `\ar@2` in xypic. I also use triple and quadruple arrows in xypic, with `ar@3` and `ar@4` (the last one is a custom shaft).
My question is:
How is it possible to draw triple/quadruple arrows in Tikz?
I am willing to try and define custom arrow shafts if need be, but I can't find how to do that in the tikz manual (which is quite formidable by the way).

This will ensure your page number is always at the top leftmost corner, sharing the same baseline as your running chapter header (dashed blue line for comparison):
**How it works:**
In this new code, instead of having a header left side and header right side for even pages, I simply empty the header right side. On the left side, I construct a box exactly the same width of the header, and I flush everything to the right (`\raggedleft`). On the first line, I insert the page number (`\thepage`), a horizontal space (`\hfill`), and the running chapter head (`\leftmark`). This creates the appearance of a distinct "left side" and "right side," and ensures the page number and first line of the running head are always on the same line.

Above is the code I am trying to use but for some reason, it is not showing up on the compiled pdf.
So, I am using the online version of overleaf so I don't think the issue is with my version. Also, below is the entire code I am currently using:
```
\documentclass{article}

\title{CPSC}

\date{July 2023}
\begin{document}
\maketitle
\section{Question 1}
Hello
\begin{figure}
\centering
\includegraphics[width=\linewidth]{Cute Goat In Pink.jpg}
\caption{Daredevil}
\label{fig:my_label}
\end{figure}
Goodbye
\end{document}
```
Unfortunately, the only thing showing up is hello and goodbye.
As for the picture name, that is how it is saved. I tried replacing it with another one that is in all small letters with no spaces and still had the same issues.
The log files in the pdf are showing absolutely no errors which is making me even more confused. And I copied this code directly from Overleaf so theoretically, it should work.
| https://tex.stackexchange.com/users/301549 | Image is showing up on visual editor but not on compiled pdf | true | `figure` is a floating environment. This means, if the image + caption does not fit to the current page (depending on the [floating parameters](https://tex.stackexchange.com/q/39017/277964)) it can be moved to the next page. This seems to be also the case here.
Note, that the default placement of `article` if `tbp` (top, bottom, page). So a `figure` somewhere at the page will not be printed, where it has been placed in the source, but only at the top or bottom of this or the next page or at a page on its own.
Additionally you've placed the float inside a paragraph. Note, that even if you'd change the float parameters using `\begin{figure}[!htbp]` it would not be printed between “Hello” and “Goodbye” but at first after “Goodbye“, because LaTeX will not print it before the end of the current line.
So to have a replacement image between “Hello” and “Goodbye”, I would not only have to change the floating options, but also add a paragraph (empty line) before “Goodbye”:
```

```
If your image is higher than the replacement `example-image`, you may also need to reduce the size by changing `\includegraphics` option `width=\linewidth`.
But if you don't want the image to float, another solution could be to [not use a floating `figure`](https://tex.stackexchange.com/q/8625/277964).

https://tex.stackexchange.com/questions/692048 | -2 | How may one define a symbol as `\sqsubset` but without the top line, and another symbol as `\sqsubset` but without the bottom line?
Edit 1:
At this point I use `\[x\bm{\sqsubset} y\longeq x \ \raisebox{-0.1pt}{\rotatebox[origin=c]{270}{L}} \ y\wedge x \ \raisebox{-2pt}{\rotatebox[origin=c]{270}{\reflectbox{L}}} \ y\]` , under graphicx and bm, and amsmath etc.
The problem is to have `\raisebox{-0.1pt}{\rotatebox[origin=c]{270}{L}}` and `\raisebox{-2pt}{\rotatebox[origin=c]{270}{\reflectbox{L}}}` as similar as possible to `\bm{\sqsubset}`.
The solution I have may be satisfactory, but it is not optimal.

The only difference between the standard version of the command and the one defined in `rapport3` is the addition of a `\parskip\z@`. So we can undo that change before loading `tocloft` and then reimplement it afterwards:

https://tex.stackexchange.com/questions/692340 | 0 | I'm just asking if it is possible to insert LaTeX into a social networking app? If so, how?
| https://tex.stackexchange.com/users/301582 | How to insert LaTeX into an application | false | If you are simply talking about LaTeX code without the possibility of having it typeset into input, you can include that just about anywhere because it is usually only ASCII characters, occasionally accompanied by Unicode characters.
As far as I currently know, including a full LaTeX implementation into something like a social media platform has not been done and indeed may not be possible. The reason is rather deceptive in that many developers say they "support LaTeX" when in fact what they really mean is that they support a LaTeX-like command syntax (i.e. commands that begin with a backslash character). This alone does not mean actual LaTeX is in use. I elaborate on this in my answer <https://tex.stackexchange.com/a/648198/218142>.
As an example from social media, consider the [Mathstodon.xyz](https://mathstodon.xyz/about) instance. The term "LaTeX" is advertised but it really uses [MathJax](https://www.mathjax.org/), a JavaScript library that indeed mimics a lot of LaTeX's capability. You can examine the source code for Mathstodon on their GitHub home <https://github.com/christianp/mastodon>.
Similarly, [Jupyter Notebook](https://jupyter.org/) sometimes claims support for LaTeX, but it too uses MathJax. You can export a notebook to TeX, but I have never experimented with that and have no idea how good the generate code is. Still, processing that code requires a local TeX Live (or similar) installation.
Using actual LaTeX requires an extensive backend including a processing engine. On my current TeX Live 2023 installation, the `pdftex` engine is 5.3MB in size and that engine would need to be present somewhere in the machinery for every user to make use of it.
If you count WordPress blogs as "social media" then I know of one plugin that does indeed use an actual LaTeX distribution, [Quick LaTeX](https://www.holoborodko.com/pavel/quicklatex/). It works by piping the LaTeX markup to a server where it is processed natively by a TeX Live distribution and then returned to the blog as an image. Still, unlike the other systems I describe it allows for LaTeX packages and genuine LaTeX markup. This model may be worth looking into but I have no knowledge about whether or not it would scale to a social media platform with millions of users.
The only large scale software package I use, and that I am aware of, that uses a locally installed LaTeX distribution is [Manim Community](https://www.manim.community/), a fork of the Python-based animation system used by [3Blue1Brown](https://www.3blue1brown.com/). Indeed, it requires a local TeX Live or other suitable TeX/LaTeX distribution (I haven't tested it with MikTeX).
In summary, due to the extensive backend requirements, to my knowledge it is not (yet?) possible to integrate full LaTeX capability into something like a social media platform. I hope someone someday finds a way to do it because I think it would be immensely useful.

I tried shrinking the nine lines of definition into one for loop but it didn't work. My intention was that as a loop iterates through 1 to 9, it would expand `\alphalph{\iteration}` first, which would be combined with `\myvarx` to become `\myvarxa`, `\myvarxb`, ..., `\myvarxi`. In the same way `#\iteration` would expand to `#1` to `#9`. However I probably got the syntax wrong.
```

\functestb{1}{2}{3}{4}{5}{6}{7}{8}{100}

```
```
! Illegal parameter number in definition of \functestb.
```
Then I replaced `#\iteration` with a constant to see if I got the rest of the code right. Nope. What is the right way to achieve what I want? The reason I am not directly accessing `#1` to `#9` is because I will write a more complex command in which the nine numbers given need to be saved and changed multiple times. I am open to alternatives such as passing a list as a parameter or generating a list inside the command if it is possible to do so in LaTeX.

https://tex.stackexchange.com/questions/692275 | 1 | Been away for ~10 days -- came home to find a couple of packages on my LaTeX install (MikTeX latest, Win 10 pro) needed updating, including newtx, which I use as the primary font for many of my documents.
I tried compiling a document that pre-upgrade compiled without warning/error. But, post-update, I now get the following when rendering from the .ps -> .pdf file using ps2pdf:
```
Querying operating system for font files...
Can't find (or can't open) font file %rom%Resource/Font/%rom%R.
Can't find (or can't open) font file ntxsym.
Didn't find this font on the system!
Substituting font Courier for ntxsym.
```
Did a quick search, and was surprised to find not a single mention of 'font file ntxsym' anywhere. So, perhaps *not* surprised ps2pdf couldn't find the font file, since even the almighty and omnipotent Google search engine hasn't either. ;-)
Any suggestions? Thanks in advance...
| https://tex.stackexchange.com/users/16184 | can't find "ntxsym" font file | false | In this case, the problem as described arose as an artifact of changes in how newtx interprets/uses AMS symbol arguments I was passing to newtx. I had been successfully using the following as part of my preamble (my larger documents usually have anywhere from 20-30 packages involved, so sussing out weird interactions can be time consuming).
```
% use AMS math package for more control over equations
\usepackage{amsmath,amssymb}
\usepackage{mathtools}
% use following for better formed clones of Times
\usepackage{newtxtext}
\usepackage[cmintegrals,cmbraces,nosymbolsc]{newtxmath}
\usepackage[scr=rsfso]{mathalfa}
```
The problem was that recent changes to newtx, in particular newtexmath which supports its own AMS symbol set,conflicted in some funky way with the amssymb package. So, tweak
```
\usepackage[cmintegrals,cmbraces,nosymbolsc]{newtxmath}
```
to
```
\usepackage[cmintegrals,cmbraces,noamssymbols]{newpxmath}
```
and...problem solved.

with `xelatex` version `XeTeX 3.14159265-2.6-0.999992 (TeX Live 2020/Debian)`, I have the following problems:
* the vertical borders are not perfectly aligned
* I can't use psutils release 1 patchlevel 17 prior to use pdftops
`gs` can read the PDF file correctly, but not `pstops` nor `psresize`.
The PDF file prints, but cropped (expected behavior).
Using `pdf2ps` helps. It makes the file compatible with `pstops`, but I have to specify the paper size to avoid cropping the top border:
```
pdf2ps -paper=A4 frame-2.pdf frame-2.ps
```
Using `pstops "@0.8(21mm,29.7mm)" -pA4 frame-2.ps frame-2ss.ps` produces a file that
* prints as desired on A4 paper.
* is not shown properly centered by `gs`.

I tried shrinking the nine lines of definition into one for loop but it didn't work. My intention was that as a loop iterates through 1 to 9, it would expand `\alphalph{\iteration}` first, which would be combined with `\myvarx` to become `\myvarxa`, `\myvarxb`, ..., `\myvarxi`. In the same way `#\iteration` would expand to `#1` to `#9`. However I probably got the syntax wrong.
```

```
```
! Illegal parameter number in definition of \functestb.
```
Then I replaced `#\iteration` with a constant to see if I got the rest of the code right. Nope. What is the right way to achieve what I want? The reason I am not directly accessing `#1` to `#9` is because I will write a more complex command in which the nine numbers given need to be saved and changed multiple times. I am open to alternatives such as passing a list as a parameter or generating a list inside the command if it is possible to do so in LaTeX.

As you see, the function gets any definition you like and the values are given as a list.
The trick is to replace `#<digits>` with `\seq_item:N \l_tmpa_tl { <digits> }`, so we have a syntax similar, but not restricted to nine parameters, to a macro definition.

I check in the web and also StackExchange but I only find very complicated examples including so much other things not directly related to key-value syntax.
So, how can I just put such a minimal key-value command?
| https://tex.stackexchange.com/users/30933 | Simple key-value example | false | With `expkv-cs` minimal key=value macros are very easy to implement.
In this case we may also want different behaviour if a key was given or not. This can be achieved relatively easy by one level of indirection, where the first level contains the default value if nothing was supplied, and the second level adds markup/formatting instructions if a key was used. This way we don't need any tests in the macro replacement but can directly use the values (even if they are empty). For this purpose the following uses `-internal` for the real keys, but adds wrappers around those which add stuff like `\par\noindent` or similar.
```

https://tex.stackexchange.com/questions/692381 | 3 | I work with a small company (10 people). I've been a LaTeX user for roughly 20 years. We have been trying to implement LaTeX as the primary document preparation system in our company with varying levels of success. The group of people who usually end up preparing documents (proposals, reports, invoices, letters, etc.) are all familiar with LaTeX.
We need to prepare documents that can be shipped both in PDF form and in printed form. The company has a standard letterhead (a header and footer) with which documents should be prepared. All documents go in this letterhead. The PDF is shipped on email. Then the same document is printed on pre-printed stationery and sent across, when required.
We started by implementing a package that will generate the headers based on a custom command in the document source (something like `\GenerateForPrint`). We used `fancyhdr` for this. Lately we adopted KOMA-script, because of the flexibility. While going through the KOMA-script docs, we figured that we were implementing this as a bunch of hacks that muck with things like page dimensions and margins. We have had problems in the past with our "package", which we now realise is because of these crude hacks we put in.
We want to understand the right way of doing this. How should the base template be? Should it be a package or a document class or?

(Not the legal/letter paper size, but a real, old-school letter, possibly in A4 format. Correct me, if I am wrong.) There are multiple ways to do this, obviously.
How extensive und numerous are your commands? A package is basically just a collection of (La)TeX commands, so this might be an obvious choice. That said, KOMA letters (Are you using either `scrletter` or `scrlttr2`?) support so-called `.lco`files, which can be loaded at run time, like so:
```
\LoadLetterOption{myprint}
%\LoadLetterOption{myemail}
```
… which would import `~/texmf/tex/latex/myprint.lco` by default. This allows for a quick and relatively painless implementation of a coherent corporate identity. Take a look at this [commented example from Washington State University](https://github.com/komascript/notepaper-wsu/tree/main) to get an idea and get you started.

| https://tex.stackexchange.com/users/199920 | What's the difference between different LaTeX versions like LiveTex, KaTex MacTex etc? | false | TeX live isn't "LaTeX verison", it is a **TeX distribution**. It includes TeX interpreter (in various modifications: pdfTeX, XeTeX, LuaTeX) and additional software: macros, fonts, drivers, additional tools. One of such additional software is LaTeX: a set of macros used by TeX interpreters. TeX is able to read macros. When a TeX interpreter reads a set of LaTeX macros then somebody calls it as LaTeX interpreter. But there are various different sets of macros for TeX: plain TeX, OpTeX, ConTeXt. There is no only LaTeX. All this software is part of the TeX live distribution.
MacTeX is another TeX distribution.
KaTeX and MathJax have no common with TeX, they only use TeX-like syntax for math formulas in html language.

https://tex.stackexchange.com/questions/692387 | 0 | While designing a custom title page for a beamer presentation I want to position a logo in the top right corner using the same marging like the rest of the page.
According to the [beamer documentation](https://www.ctan.org/pkg/beamer) page 76 the default value for the left/right margin size is 1cm.
But I don't want to rely on a default value, I want to use whichever value might have been set with `\setbeamersize{text margin right=whatever}`.
Ideally I would want to do this:
```
\hspace*{\getbeamersize{text margin right}}%
```
But there is no command `\getbeamersize`. How do I get the margin in a document using the beamer class?

https://tex.stackexchange.com/questions/692405 | 2 | Packages can specify that they need a specific version of LaTeX using [`\NeedsTeXFormat`](https://tex.stackexchange.com/questions/160802/what-date-should-i-specify-in-the-optional-argument-of-needstexformat), which takes something like `LaTeX2e`, and an optional release-date which the latex-version used must be newer than.
Since packages cannot specify an exact release date or an "older-than" release date, can I download the newest release of the specified LaTeX-version (e.g. `LaTeX2e`) and have a guarantee that all packages that NeedTeXFormat `LaTeX2e` work with this?
In other words, do releases of LaTex-versions have backward compatibility?
Also, according to [this answer here](https://tex.stackexchange.com/a/13550/293514), when I compile a document with say pdflatex, it uses a file `latex.ltx`. Am I right in assuming that the latex-version and release date one can specify in `\NeedsTeXFormat` refers to the version and release date of the `latex.ltx` file?
| https://tex.stackexchange.com/users/293514 | Do packages work only with a specific version of LaTeX? | true | There are literally thousands of packages on ctan many have not changed for decades and have worked with all latex releases over that time. Some sometimes need to adjust to a change in the format. It all depends.
Most packages using `\NeedsTeXFormat` do so as they use a new command not available in older formats, but they expect to work for later formats, and that is what the command checks, it does not check that a format with exactly that date is in use, just that a format no later than that date is in use.

```
In presentation mode, the `\mergeFrame` does nothing. In article mode, it sets up a line-gobbler until it sees `\begin{block}` (included). It then lets the content show up, until it sees `\end{block}`, which it replaces with `\end{preuve}`. Therefore, in article mode, LaTeX saw a single `preuve` environment. We `\refstepcounter{framenumber}` when going out from gobbling mode, although this should not be very relevant in article mode.

https://tex.stackexchange.com/questions/692430 | 0 | My goal is to quote two paragraphs using the `amsart` document style, with both paragraphs in the quotation being formatted in ordinary paragraph style, i.e. with the crown line indented.
The LaTeX Book on p. 26 says that the "quotation" environment is for quoting material that is entire paragraphs, and shows an example with the formatting I desire. The [AMS-LaTeX guide](http://homepages.math.uic.edu/%7Ehurder/math589/TeX/amshelp.pdf) does not describe quotations at all.
Testing shows that in `amsart` the "quotation" environment does not indent the first line of the quotation, but if the quotation contains an empty line the first line following it will be indented.
That is, the first paragraph is not paragraph-formatted but the second paragraph is paragraph-formatted. (The "quote" environment produces the same formatting, contra the LaTeX Book which says that "quote" is for non-paragraph-formatted text.)
Presumably there is a known way to do this but I haven't been able to find the documentation.

https://tex.stackexchange.com/questions/692443 | 9 | Both `ltluatex.tex` (from the LaTeX kernel) and `luatexbase.sty` (as an add-on package) share the same Lua namespace, namely `luatexbase`; they also share functions with the same name. However, these functions are not compatible – in particular, `luatexbase.add_to_callback` differs.
What is the recommended, future-proof way to find out whether the stuff from `ltluatex.tex` is used? Or to say it differently, I want to reject `luatexbase.sty`.
| https://tex.stackexchange.com/users/20911 | `ltluatex.tex` vs. `luatexbase.sty` | true | As with any latex package you can prevent it loading via
```
\@namedef{ver@luatexbase.sty}{}
```
so latex thinks it is already loaded.
But there should be no need
The current `luatexbase.sty` was written at the same time as `ltluatex`, by the same people, it is intended as a compatible extension, replacing the original `luatexbase.sty` that pre-dates `ltluatex`.
The extended `luatexbase.add_to_callback` has an extra optional `priority` argument but if it is not used, the behaviour is as in `ltluatex` and either way the actual registering of the callback is done via the `ltluatex` version (saved as `luatexbase.base_add_to_callback`). The extended version just re-orders the callback list if `priority` is used. All the internal tables recording the callbacks are the ones defined by `ltluatex`.

There are many things I do not understand:
**QUESTION 0:** Why does `\pgfkeyssetvalue{/myclass/optionX}{#1}` and `\pgfkeys{/myclass/optionX = #1}` lead to different results?
**QUESTION 1:** Why printing `\pgfkeysvalueof{/myclass/optionX}` and `\myclass@optionX` lead to different results while I would expect the `.store in` to make the two equivalent?
**QUESTION 2:** Why `defineA(A2)` change also the value of `\myclass@optionB`? I would have expected the `optionB = \myclass@optionA` during the definition of `pgfkeys` to just be an initialization instead of having a permanent link between the two.
**QUESTION 3:** Is there a way to define the `pgfkeys` to that `\pgfkeysvalueof{/myclass/optionX}` and `\myclass@optionX` are synonymous always correspond to the same value, including for example a change through `\pgfkeyssetvalue{/myclass/optionX}` or a `\pgfkeys{/myclass/optionX = XN}`?
**QUESTION 4:** How to initialize the `pgfkeys` so that `optionB = \myclass@optionA` only initialize `\myclass@optionB` with the value of `\myclass@optionA` (but if `\myclass@optionA` is changed later, it does not change the value given by `\myclass@optionB`) as in:
```
\printoptions % => [A = (, A0)] [B = (, A0)]
\setA{A1}
\printoptions % => [A = (A1, A0)] [B = (, A0)]
\defineA{A2}
\printoptions % => [A = (A1, A2)] [B = (, A0)] % Difference here: B stays the same!!!!
\setB{B1}
\printoptions % => [A = (A1, A2)] [B = (B1, A0)]
\defineB{B2}
\printoptions % => [A = (A1, A2)] [B = (B1, A0)]
```
More generally, I think I am missing the big picture of what is going behind the association of `pgfkeys` and `macros`, so any big picture explanation will be appreciated.
| https://tex.stackexchange.com/users/17200 | Pgfkeys associated with macros lead to unexpected results | false | This attempts to be the "big picture" answer, even though this answer just focuses on a single aspect of `pgfkeys`, namely how to store values given to keys for later use: `.store in` and `\pgfkeyssetvalue`/`.initial`.
In general `pgfkeys` has two ways to store values:
1. Storing the value inside the key path
2. Storing the value in some macro
You can achieve the first by using the `.initial` handler to define the key (`\pgfkeys{/foo/.initial = 1}`), and then access the value by using `\pgfkeysvalueof` or `\pgfkeysgetvalue`. This simply hides the macro in a non-obvious name and adds a level of indirection, the advantage being that the same name to set the key is used to get its value, instead of another macro name.
The second is what `.store in` sets up, so `\pgfkeys{/foo/.store in = \foo}`. This sets things up such that each time the key is set the definition of `\foo` is changed to expand to the given value. The advantage is that you get more control over where stuff is stored, and have an easier life expanding it. The drawback is yet another name for the same thing.
When you use `\pgfkeyssetvalue{/foo}{bar}` you're only assigning to the first storage, you don't call the code that was set up by the `.store in` handler, so the assignment is not made to `\foo`, but only to the key path `/foo`.
Which of the two you prefer (and which is to be preferred) isn't dictated, `pgfkeys` gives this choice to the user. And while this choice *per se* isn't something bad, it sometimes (like in your case), leads to confusion. I'd advice to select one of the mechanisms and stick to it for one project (that doesn't mean another project by the same author can't use the other approach).
Personally I'd prefer the second approach, as I don't see the gain of that level of indirection (and my own key=value implementation -- *advertisement block:* `expkv` -- doesn't support the other). Others (like [@Qrrbrbirlbel](https://tex.stackexchange.com/questions/663260/pgfkeys-associated-with-macros-lead-to-unexpected-results#comment1649757_663260)) prefer the first approach.

https://tex.stackexchange.com/questions/692455 | 0 | Originally, I intended to use the command $\not\mathcal{R}$ as the negation of a binary relation, but there is a problem with that concatenation of commands. So I did what anyone would do in a situation like this, which is create my own symbol.Searching for information on this page, I came across the following code:
```
\newcommand{\TCNegacion}[1]{%
\mathrel{\fbox{\ooalign{$#1$\cr\hidewidth\raisebox{0.5ex}{\rotatebox[origin]{80}{\rule{0.5cm}{0.5pt}}}\hidewidth\cr}}}
}
```
This code solves the initial problem, but it generates another one, namely the concatenation of commands `$y\TCNegation{\mathcal{T}} g$` is not to my liking. I'd like to rotate it a bit more to better visualize the negation, but I lose the alignment of the characters involved.
Is there a better way to fix the initial problem?
Is it possible to improve the code?
| https://tex.stackexchange.com/users/301449 | Is there a problem with the $\not\mathcal{R}$ command? | false | You could tweak this some more but I'd use the slanted `\not` not a rule, with optional per-character offset

https://tex.stackexchange.com/questions/665946 | 1 | I am creating an image grid with many images by using the PGF `groupplots` library. I am using a for-loop with `\pgfplotsforeachungrouped`.
Each filename is structured as follows: `preamble_title_percent.jpg`. I want to extract the title and the percent value by splitting the filename. Consequently, I can use the title and percent as values in `\nextgroupplot`. How can I do it?
Unlike an ordinary `\foreach` in PGF, `\pgfplotsforeachungrouped` only works with two arguments. That's why, I guess, it is the only way to extract the title and percent on the fly within `\edef`.
Pseudo-code:
```
\pgfplotsforeachungrouped \filename in {

{
\edef\temp{
# How can I split the filename here?
