I'm trying to put together n files into one with pgfplotstable. This example works: \begin{filecontents}{data1.csv} aaa bbb ccc \end{filecontents} \begin{filecontents}{data2.csv} 111 222 333 \end{filecontents} \begin{filecontents}{data3.csv} aaa111 bbb222 ccc333 \end{filecontents} \documentclass{book} \usepackage{pgfplotstable} \pgfplotsset{compat=1.18} \begin{document} \pgfplotstableread[header=false]{data1.csv}\overallTable \pgfplotstableread[header=false]{data2.csv}\tableTwo \pgfplotstablevertcat{\overallTable}{\tableTwo} \pgfplotstableread[header=false]{data3.csv}\tableTwo \pgfplotstablevertcat{\overallTable}{\tableTwo} \begin{table} \pgfplotstabletypeset[ string type, ]{\overallTable} \end{table} \end{document} It gives what I want: But if I put the \pgfplotstableread and \pgfplotstablevertcat in a \foreach loop, they don't work: \begin{filecontents}{data1.csv} aaa bbb ccc \end{filecontents} \begin{filecontents}{data2.csv} 111 222 333 \end{filecontents} \begin{filecontents}{data3.csv} aaa111 bbb222 ccc333 \end{filecontents} \documentclass{book} \usepackage{pgfplotstable} \pgfplotsset{compat=1.18} \begin{document} \pgfplotstableread[header=false]{data1.csv}\overallTable \foreach \ind in {2,3} {the loop is executed: \ind\newline \pgfplotstableread[header=false]{data\ind.csv}\tableTwo \pgfplotstablevertcat{\overallTable}{\tableTwo} } \begin{table} \pgfplotstabletypeset[ string type, ]{\overallTable} \end{table} \end{document} Even if the loop is executed, I got no errors, and in the log I have: PGFPlots: reading {data1.csv} PGFPlots: reading {data2.csv} PGFPlots: reading {data3.csv}

Can someone help me create a macro like \MyList{A;B;C;D;E;F} which returns “A, B, C, D, E[,] respectively F" independently on how many ”arguments” (2+) that are specified and also support math, e.g. \MyList{\(A\);\(B\);\(C\);\(D\);\(E\);\(F\)} ? (I used the [,] notation since I’m not sure if the Oxford comma is used today.) If the number of arguments is two; \MyList{A;B} I would like it to return “A respectively B”. Edit: I tried using sinuitx but it might not be suitable for this task as it mainly(?) handles numbers. Here is a test \documentclass{article} \usepackage{siunitx} \begin{document} \numlist[parse-numbers=false]{A;2;3} \numlist[parse-numbers=false]{\text{A};2;3} \numlist[parse-numbers=false]{\(A+B\);2;3} \end{document} but it gives an error on the last line and I would like to have ”roman letters” if no ”math mode” is used, and avoid using \text{}.

Can I configure this loop, or a similar loop, to add rows until the end of the text body is reached? A small gap at the end will probably be unavoidable. Could this be achieved with \pdfpos? \documentclass[a5paper]{article} \usepackage[margin=14mm, showframe=true, paperheight=126mm, ]{geometry} \newcounter{mycount} \setcounter{mycount}{0} \def\mylines{}% \loop\ifnum\themycount<7% \addtocounter{mycount}{1} \expandafter\def\expandafter\mylines\expandafter{% \mylines & & \themycount \\ }% \repeat% \begin{document} \section{Table} \begin{tabular}{| c c | c|} \hline \multicolumn{3}{|c|}{Something} \\ \hline A & B & (My Head) \\ \hline a & b & n\\ a & b & n\\ a & b & n\\ \mylines \hline A & B & (My Foot)\\ \hline \end{tabular} \end{document}

I am using the amsart document class in LaTeX. I would like the table of contents to display all sections while including only a single, specific subsection. All other subsections should remain numbered and visible in the document, but should not appear in the table of contents. \documentclass{amsart} \usepackage{hyperref} \begin{document} \title{title} \author{Author Name} \maketitle \tableofcontents \section{First Section} \subsection*{This subsection should NOT appear in the TOC} \subsection{This subsection SHOULD appear in the TOC} \section{Second Section} \subsection*{Another subsection NOT in the TOC} \end{document}

Claim This post is more likely asking for better approach, focused on the arc's plot. And that is similar to, but I don't find the same one: Drawing cyclic quiver Drawing a circular graph using xypic https://tex.stackexchange.com/a/759710/322482 Descrption I found that just with： \draw[<->,shortstyle,violet] (\ang:\RR cm) arc[radius=\RR cm,start angle=\ang,delta angle=\deltaang]; The arc is not exactly centered at (0,0)(the violet part), thus I learnt from here and calculate the \deltaangg with cosline rule manually.

Any suggestions on the code?

I have always used \documentclass{article} \usepackage{fontspec} \setmainfont{Times New Roman} \newfontfamily\semibold[Ligatures={TeX, Common}]{Times LT Std Semibold} \usepackage{imakeidx} \makeindex[program=texindy, options=-L english -C utf8, title=Index] \begin{document} Some text\index{Important Topic|textbf}. Some text\index{Not Important Topic}. \printindex \end{document} to be processed with xelatex -shell-escape main.tex, which sets the page of the entry in boldface using the standard font used by \textbf{}. How can I set the page in a particular (semibold) font? Or, for that matter, any other font?

I would like text to be above a horizontal arrow in longtblr, with the following constraints longtblr package Define start and stop points of arrow relative to column borders - i.e. enable the table is dynamic if width of columns change Minimal space between arrow bar and the text Text in column A centred between rows 2 and 3 A screen grab of the desired outcome is attached. Here is a minimal example illustrating what I currently have: \documentclass{article} \usepackage{tabularray} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{longtblr}{ colspec={|c|c|c|}, vlines, hlines, row{3} = {ht=0pt}, % arrow row height } % --- First row --- A & B & C \\ % --- SECOND row: merge columns 2 and 3 --- 1 & \SetCell{c=2} 2 & \\ % --- Arrow row (thin) --- & \SetCell{cmd=\tikz[remember picture]\node (Bstart) {};} & \SetCell{cmd=\tikz[remember picture]\node (Cend) {};} \\ \end{longtblr} % --- Draw the arrow --- \begin{tikzpicture}[overlay, remember picture] \draw[red, thick, <->] ($(Bstart.west)+(-\pgflinewidth/2,0)$) -- ($(Cend.east)+(\pgflinewidth/2,0)$); \end{tikzpicture} \end{document}

Sorry everyone. I just did an update, which was probably a mistake, and encountered another problem with hyperref. For years I've been using a workaround which I borrowed from a journal, and it worked. Well, I understand that this is an undocumented feature, but there seems (seemed?) to be no other way to have everything numbered consecutively. Here's a minimal example: \documentclass{amsart} \usepackage{hyperref} \newtheorem{theorem}{Theorem}[section] \makeatletter \let\c@equation\c@theorem \let\theequation\thetheorem \makeatother \begin{document} \section{1} \begin{equation} a=b\label{1} \end{equation} \newpage \section{2} \begin{equation} c=d\label{2} \end{equation} \newpage \eqref1 \eqref2 \end{document} Both links lead to eqn. 1.1, and the log reports multiple anchors with the same name. What would the new hack be? Or is there a documented way now to have all theorems, lemmas, ... and equations numbered consecutively within sections and, at the same time, have \autoref work correctly?

I'm trying to create a LaTeX document where I have several images stacked vertically, with no extra vertical space between them, and only one caption for all images (appearing under the last image). The problem is that each \IMG creates a separate figure, so each image gets its own caption and there’s extra vertical space between images. What I want: Multiple images stacked vertically with no extra vertical space. Only one caption for all images (appearing under the last one). Allow overlays on the images (x, y, text). This is how it should look like: The code what I got from taiwan12 with little modification (link: https://tex.stackexchange.com/a/760076/287423) : \documentclass{report} \usepackage{graphicx} \usepackage{float} \usepackage{xcolor} \usepackage{xparse} \ExplSyntaxOn % variables \tl_new:N \l_taiwanxii_image_tl \tl_new:N \l_taiwanxii_caption_tl \tl_new:N \l_taiwanxii_shortcaption_tl \tl_new:N \l_taiwanxii_label_tl \tl_new:N \l_taiwanxii_pos_tl \fp_new:N \l_taiwanxii_scale_fp \fp_new:N \l_taiwanxii_overlayscale_fp \clist_new:N \l_taiwanxii_x_clist \clist_new:N \l_taiwanxii_y_clist \clist_new:N \l_taiwanxii_text_clist % keys \keys_define:nn { taiwanxii } { image .tl_set:N = \l_taiwanxii_image_tl, caption .tl_set:N = \l_taiwanxii_caption_tl, shortcaption .tl_set:N = \l_taiwanxii_shortcaption_tl, label .tl_set:N = \l_taiwanxii_label_tl, pos .tl_set:N = \l_taiwanxii_pos_tl, scale .fp_set:N = \l_taiwanxii_scale_fp, overlayscale .fp_set:N = \l_taiwanxii_overlayscale_fp, x .clist_set:N = \l_taiwanxii_x_clist, y .clist_set:N = \l_taiwanxii_y_clist, text .clist_set:N = \l_taiwanxii_text_clist, } \NewDocumentCommand{\IMG}{m} { % reset \tl_clear:N \l_taiwanxii_image_tl \tl_clear:N \l_taiwanxii_caption_tl \tl_clear:N \l_taiwanxii_shortcaption_tl \tl_clear:N \l_taiwanxii_label_tl \tl_clear:N \l_taiwanxii_pos_tl \tl_clear:N \l_taiwanxii_pos_tl \clist_clear:N \l_taiwanxii_x_clist \clist_clear:N \l_taiwanxii_y_clist \clist_clear:N \l_taiwanxii_text_clist \tl_set:Nn \l_taiwanxii_pos_tl {H} \fp_set:Nn \l_taiwanxii_scale_fp {1} \fp_set:Nn \l_taiwanxii_overlayscale_fp {1} \keys_set:nn { taiwanxii } { #1 } % shortcaption \tl_if_empty:NT \l_taiwanxii_shortcaption_tl { \tl_set_eq:NN \l_taiwanxii_shortcaption_tl \l_taiwanxii_caption_tl } \use:e { \exp_not:N \begin{figure}[\l_taiwanxii_pos_tl] } \centering \sbox0{\includegraphics[scale=\fp_use:N \l_taiwanxii_scale_fp]{\l_taiwanxii_image_tl}} \usebox0 \int_zero:N \l_tmpa_int \clist_map_inline:Nn \l_taiwanxii_x_clist { \int_incr:N \l_tmpa_int \tl_set:Nn \l_tmpa_tl {##1} \tl_set:Nx \l_tmpb_tl { \clist_item:Nn \l_taiwanxii_y_clist { \int_use:N \l_tmpa_int } } \tl_set:Nx \l_tmpc_tl { \clist_item:Nn \l_taiwanxii_text_clist { \int_use:N \l_tmpa_int } } \rlap{ \hspace{\dimexpr \l_tmpa_tl\wd0-\wd0\relax} \raisebox{\dimexpr \ht0-\l_tmpb_tl\ht0\relax}{ \makebox[0pt][l]{ \raisebox{-\height}{ \scalebox{\fp_use:N \l_taiwanxii_overlayscale_fp}{ \fcolorbox{black}{white}{ \shortstack[c]{\l_tmpc_tl} } } } } } } } \caption[\l_taiwanxii_shortcaption_tl]{\l_taiwanxii_caption_tl} \label{fig:\l_taiwanxii_label_tl} \end{figure} } \ExplSyntaxOff \begin{document} \listoffigures \IMG{ image = example-image, caption = Caption I, shortcaption = Caption, label = figA, pos = H, scale = 0.6, x = {0.0,0.5,0.2,0.7,0.8}, y = {0.0,0.2,0.3,0.65,0.9}, text = {AA\\BB,AABB,A,B,C}, overlayscale = 0.75, } \IMG{ image = example-image, caption = Caption II, shortcaption = Caption, label = figB, pos = H, scale = 0.6, x = {0.2,0.5}, y = {0.2,0.3}, text = {AABB,A}, overlayscale = 1, } \end{document}

I apologized if this is a duplicate. What is the best way to draw such figures with tikz (or other packages)? For the time being just the potato like figure. I do not care for the vectors and the infinitesimal mass element. I do not want someone to do the work for me. Just some advice or suggestions.

I want to add a topright math kern (aka cut-in or staircase kerning) to DOUBLE-STRUCK CAPITAL R (Hex value: 0x211D, Code point: U+211D). I tried the method as shown in this answer of mickep, but it does not seem to work here. \documentclass{article} \usepackage{fontsetup} \directlua{ local kerns = { ["NewCMMath-Book"] = { [0x211D] = { topright = { { kern = -500 } } }, } } local function addkerns(tfmdata) if tfmdata.mathparameters then local kerns = kerns[tfmdata.properties.fontname] if kerns then local characters = tfmdata.characters for unicode, specification in pairs(kerns) do local character = characters[unicode] if character and not character.mathkerns then character.mathkerns = specification end end end end end fonts.handlers.otf.features.register { name = "mathkerns", description = "additional math kerns", default = true, initializers = { position = 1, base = addkerns, node = addkerns, } } } \usepackage{lua-visual-debug} % The absence of a red rectangle between the doublestruck R and the superscript n seems to indicate that math kerning is not being used, if I understand correctly. \begin{document} \(\symbb{R}^n\) \end{document} While I am using LuaLaTeX with unicode-math, answers for other engines such as ConTeXt and OpTeX are also welcome, if the resulting code is different. Edit: I have tried loading the fonts manually, but that also does not seem to work. \documentclass{article} \directlua{ local kerns = { ["NewCMMath-Book"] = { [0x211D] = { topright = { { kern = -100 } } } } } local function addkerns(tfmdata) if tfmdata.mathparameters then local kerns = kerns[tfmdata.properties.fontname] if kerns then local characters = tfmdata.characters for unicode, specification in pairs(kerns) do local character = characters[unicode] if character and not character.mathkerns then character.mathkerns = specification end end end end end fonts.handlers.otf.features.register { name = "mathkerns", description = "additional math kerns", initializers = { position = 1, base = addkerns, node = addkerns, } } } \usepackage{unicode-math} \setmainfont{NewCM10-Book.otf} \setmathfont[ StylisticSet={3}, BoldFont = NewCMMath-Bold.otf, RawFeature=+mathkerns ]{NewCMMath-Book.otf} \usepackage{lua-visual-debug} \lvdset{glyph={show=true}} \begin{document} \(\symbb{R}^n\) \end{document}

I would like node B to have exactly the same width as node A, without explicitly specifying a fixed dimension, with the following constraints: The two nodes are not adjacent in the source code. I do not want to hard-code a width (e.g., minimum width=3cm). Node A will always be at least as wide as node B. I would prefer a solution that does not rely on manually computing dimensions via \path let unless necessary. Here is a minimal example illustrating what I currently have: \documentclass{article} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture} \node [draw] (A) {Some text}; \path let \p1 = (A.south west), \p2 = (A.north east) in node [draw, minimum width=\x2-\x1-\pgflinewidth, minimum height=\y2-\y1-\pgflinewidth, below right] at ([yshift={\pgflinewidth}]A.south west) {more}; \end{tikzpicture} \end{document}

I'm trying to set up some parameters of nodes from lua code. I don't understand why the first version works but not the second. \documentclass[border=10pt]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} \node [ color=\directlua{ tex.print("red") } ] {A}; \node [ \directlua{ tex.print("color=red") } ] {B}; \end{tikzpicture} \end{document} To me it looks like that these two directlua sections should produce the exact same output, but B fails with the following error message: ! Package pgfkeys Error: I do not know the key '/tikz/color=red' and I am going to ignore it. Perhaps you misspelled it.

I'm trying to use \qedhere with the ams classes to set a proof endmark at the end of an align environment. But doing so removes the number from that equation! This problem doesn't happen with a single numbered equation. Here are some examples. In the last one, I have a sort of hack from this question that adds a paragraph break and then a negative \vspace. But, the spacing isn't quite right and I wouldn't want to manually adjust it for each different environment. I've also seen a similar suggestion for a multi-line display. Is there not a better way? \documentclass{amsart} \begin{document} \begin{proof} Numbered equation, qedhere at right. \begin{equation} x+y\qedhere \end{equation} \end{proof} \begin{proof} Align environment; qed on newline \begin{align} x & = 2\\ y & = 3 \end{align} \end{proof} \begin{proof} Align environment; using qedhere blocks the final equation number \begin{align} x & = 2\\ y & = 3\qedhere % <---- want a number here too \end{align} \end{proof} \begin{proof} Align environment; paragraph break and negative vspace \begin{align} x & = 2\\ y & = 3 \end{align} \par\nopagebreak\vspace{-\baselineskip}\mbox{} \end{proof} \end{document} Note: Several related questions, like this one for the cases environment, have comments suggesting that it's just bad style to end a proof with a displayed equation. Leaving that aside, I'm really interested in different endmarks for different environments. The proof environment is just the simplest way to display the issue with \qedhere and align. Note 2: I also see suggestions that ntheorem handles endmarks better. I've used ntheorem for many years, but it hasn't been updated since 2011. I'm looking for a better solution using the new begin/end environment hooks. I had hoped \qedhere in the appropriate hook could do the job.

Consider the following minimal example where I want to draw a rectangle behind a sequence of numbers (to highlight them): \documentclass{article} \usepackage{tikz} \usetikzlibrary{backgrounds,calc} \NewDocumentCommand{\tikzmark}{ m }{\tikz[overlay, remember picture] \node (#1) {};} \newcounter{seq} \NewDocumentCommand{\seqstart}{}{% \stepcounter{seq}% Start a new sequence \tikzmark{seq-start-\theseq}}% Set start marker \NewDocumentCommand{\seqend}{}{% \tikzmark{seq-end-\theseq}% Set end marker \tikz[remember picture, overlay] \scoped [on background layer] \fill [fill=blue!10!white] ($(seq-start-\theseq.south west) + (-0.5pt,1pt)$) rectangle ($(seq-end-\theseq.south east) + (0.5pt,1.1\normalbaselineskip)$);% } \begin{document} \[ 12, 15, 8, 11, 4, 7, 0, 3, 16, 19, 12, 15, 8, 11, 4, 7, 0, 3, \ldots \] \[ \seqstart{}12, 15, 8, 11, 4, 7, 0, 3, 16, 19\seqend{}, 12, 15, 8, 11, 4, 7, 0, 3, \ldots \] \end{document} The idea is that \seqstart would set a (counter-driven) \tikzmark representing the start of the sequence to be marked. Then \seqend would set a \tikzmark at the end and highlight it using the background layer. The counter allows for multiple such sequence marking within a larger document. However, the output shows that the rectangle highlighting a part of the sequence is not being drawn on background layer as requested. Why is that? How can I ensure the rectangle is drawn on the background layer behind document/text elements? The backgrounds library documentation (in the tikz documentation, section 45) mentions that on background layer can only be used inside a {scope} or \scoped, which is done above.

First off, here is my setup because I am certain that must be part of the problem. I'm using: texlive 2025 VS Code with these extensions: LaTeX by Mathematic Inc LaTeX Workshop by James Yu I have a LaTeX document that used to build just fine. I recently tried switching over to using the tcolorbox package instead of the soul package for highlighting in that document. As part of that process, I was getting some errors, and from reading various posts online for similiar issues I suspected I had an outdated texlive distribution so ended up trying to update everything with this on my command line: tlmgr update --all This appeared to fix the errors with tcolorbox, but I then realized that tcolorbox does not break across lines nicely so switched back to using soul. But now my document will not build. It is stuck in an infinite loop or something, the status at the bottom of VS code has the spinning circular arrows next to "Build" and it just spins forever. I have narrowed the problem down to when I use \hl inside of a longtable. Minimum working code is below. If I uncomment the commented line, I get the building-forever behavior. \documentclass{article} \usepackage{longtable} \usepackage{soul} \usepackage{xcolor} \begin{document} \sethlcolor{yellow}\hl{Test text} \begin{longtable}{ll} Column 1 & Column 2\\ % \hl{Test text} & Entry 2 \\ \end{longtable} \end{document} I have completely removed and re-installed my texlive installation and am still getting the same result. When I click "Kill LaTeX compiler process" twice to stop the infinite build, I get a popup saying "Recipe terminated with error".

In this answer https://tex.stackexchange.com/a/133357 to a question regarding TikZ I found the following comment inside a \tikzset: % Use csname so catcode of @ doesn't have do be changed. This leaves me wondering if using \csname has any advantage over changing the catcode of @ by wrapping \tikzset with \makeatletter - which inside a package wouldn't even be neccesary since inside a package @ is of catcode letter by default. Is the use of \makeatletter potentially problematic (in general or inside pgfkeys)? If so: In which cases is it advisable to use \csname instead of \makeatletter? As far as I can imgine it (practically?) should be just a matter of taste, otherwise using such code inside a package where @ is of catcode letter would be problematic?!

I love LaTeX, but I also love french typography and I noticed that babel does not really add a thin space before the colon/semicolon: \documentclass{article} \usepackage[french]{babel} \addto\extrasfrench{% \renewcommand{\FBcolonspace}{\nobreak\thinspace}% } \begin{document} \large Le canard: un animal avec deux pattes. \end{document} Built with: latexmk -lualatex test.tex If I manually do it, the result is visually much better. \begin{document} \large Le canard\nobreak\thinspace: un animal avec deux pattes. \end{document} Is there a way to tweak babel to do it right?

In the graph below the red "dots" get distorted due to unequal scaling.

Is it possible to log the contents of \l_tmpa_box without altering pdfTeX's exit code?

In texmaker how can you put a character (or more) between dollars automatically, just like you can do with emphasis. For example: x=y -> select and execute a command -> $x=y$

I wrote a command that puts a string in italics either in math mode or in text mode. I use it for typing "types". They have to be in italics in my theory and so it is not just \textit but the command says something about the content. Now, for some situations my macro has strange effects. While \emphputs a following comma close to the italicized "f", my command does not. Is there a way to achieve this? Edit: The italics should come out as normalfont italics even if the environment is small caps: \textsc{\type{inf}}. \documentclass{scrartcl} \newcommand{\type}[1]{\ifmmode\mathit{#1}\else\textnormal{\textit{#1}}\fi} \begin{document} \noindent \emph{inf},\\ \type{inf}, \end{document}

Since I am starting to use LuaLaTeX as compiling engine and I cannot use xypic with pdf option in LuaLaTex, I wonder if there is a good way to make tikz produce loop curves like the one produced by xypic. Also luamplib code is welcome.

I'm writting report in "Tufte-style" with scrreprt koma-script class. I'm quite happy with the result, but I cannot figure out how to put a figure in full width of the page. I want to keep using koma-script (instead of tufte-style class) because my document contains numerous formating options. To make the report looking like Tufte-style and avoid some conflicts in the margin section, I use : sidenotesplus (provides fullwidth environment with \begin{figure*}…\end{figure*}) marginfix (to avoid conflicts like overlapping, or shifting out of page in margin) Here is the MWE (I only keep 1/3 of all packages, but the misbehavior keep happening). First remark : Claude suggests me calling the addmarginenvironnement. It works, but that does not solve the root issue. Second remark: I thought of a conflict between koma-scriptand geometrypackages. I tried to disable geometryand setup the typearea and margin dimensions with koma options -> same result with the figure shifting on right.

I've been writing some commands that I use to randomize writing exam questions. I currently have the following code for generating "variables" containing (possibly non-zero) random integers: \newcommand{\randIntLower}{1} %Lower bound on rand ints \newcommand{\randIntUpper}{5} %Upper bound on rand ints \newcommand{\randIntTemp}{} %Used for defining values in randInts \newcommand{\randInts}[2][]{% % #1 = option (default: []; Use nz for nonzero) % #2 = list of variables % Uses \randIntLower and \randIntUpper as bounds (change with renewcommand if needed) \foreach \var in {#2}{% \ifstrequal{#1}{nz}{% % nonzero method: produces +/- nonzero random integers \pgfmathparse{int(ifthenelse(rand > 0, 1, -1)*random(\randIntLower,\randIntUpper))}% \expandafter\xdef\var{\pgfmathresult}% }{% \pgfmathrandominteger{\randIntTemp}{\randIntLower}{\randIntUpper}% \expandafter\xdef\var{\randIntTemp}% }% }% } This gives me something like this: \randInts[nz]{\randOne,\randTwo,\randThree} %\randOne -> 4 %\randTwo -> -2 %\randThree -> 4 This code works well enough, with the exception that I might get repeat random numbers. I've also been running into some of the limitations of pgfmath, so I'm now trying to rewrite the above using LaTeX3 syntax (hopefully fewer issues with calculations, and optional arguments aren't as positional). My hope is to have something that behaves as such: \randInts[nz]<1>(5){randOne, randTwo, randThree} %\randOne -> 4 %\randTwo -> -2 %\randThree -> 4 \randInts*[nz]<1>(5){randOne, randTwo, randThree} %\randOne -> 4 %\randTwo -> -2 %\randThree -> 6 It grieves me to say this, but I've been trying to write this with the help of Github's CoPilot. I have been reading whatever Latex3 documentation I could find (e.g. xparse, expl3, l3kernel), but for now, this is what I've got: \ExplSyntaxOn% % Flag: whether to generate ±nonzero \bool_new:N \l__randints_nonzero_bool % Parsed bounds \int_new:N \l__randints_min_int \int_new:N \l__randints_max_int \bool_new:N \l__randints_unique_bool \clist_new:N \l__randints_used_clist \int_new:N \l__randints_range_len_int \int_new:N \l__randints_slots_int % \randInts[nz?]<min>(max){name1,name2,...} % - [nz] or [nonzero]: produce ±(magnitude), where magnitude in [min,max] % - <min> and (max) are *separate* optional delimited args; defaults are 1 and 5 % - names are bare (no leading \); defines \name globally to the drawn integer \cs_new_protected:Npn \__randints_pick_unique:nn #1 #2 { \int_set:Nn \l_tmpa_int { \int_rand:nn { #1 } { #2 } } \prg_do_while:nn { \clist_if_in:NnTF \l__randints_used_clist { \int_to_arabic:n { \l_tmpa_int } } { \prg_return_true: }{ \prg_return_false: } } { \int_set:Nn \l_tmpa_int { \int_rand:nn { #1 } { #2 } } } } \cs_new_protected:Npn \__randints_pick_unique_signed:nn #1 #2 { % Loop until we find a nonzero signed value not yet used \int_zero:N \l_tmpa_int \prg_do_while:nn { % pick magnitude \int_set:Nn \l_tmpb_int { \int_rand:nn { #1 } { #2 } } % reject zero magnitude \int_compare:nNnTF { \l_tmpb_int } = { 0 } { \prg_return_true: } { % pick sign and form signed value \int_set:Nn \l_tmpc_int { \int_rand:nn { 0 } { 1 } } \int_set:Nn \l_tmpc_int { \int_eval:n { ( \l_tmpc_int * 2 - 1 ) * \l_tmpb_int } } \clist_if_in:NnTF \l__randints_used_clist { \int_to_arabic:n { \l_tmpc_int } } { \prg_return_true: } { \int_set:Nn \l_tmpa_int { \l_tmpc_int } \prg_return_false: } } } { } } \NewDocumentCommand \randInts { s o D<>{\randIntLower} D(){\randIntUpper} m } { % Determine nonzero mode from [ #2 ] \bool_set_false:N \l__randints_nonzero_bool \IfNoValueF{#2}{ \tl_if_eq:nnT {#2} {nz} { \bool_set_true:N \l__randints_nonzero_bool } } % starred variant -> unique values (no repeats): #1 is boolean from `s` \IfBooleanTF{#1} { \bool_set_true:N \l__randints_unique_bool } { \bool_set_false:N \l__randints_unique_bool } % Normalize order (so <7>(3) becomes [3,7]) \int_set:Nn \l_tmpa_int { \int_min:nn { \l__randints_min_int } { \l__randints_max_int } } \int_set:Nn \l_tmpb_int { \int_max:nn { \l__randints_min_int } { \l__randints_max_int } } \int_set_eq:NN \l__randints_min_int \l_tmpa_int \int_set_eq:NN \l__randints_max_int \l_tmpb_int % If unique requested, check availability and clear used list \int_set:Nn \l__randints_range_len_int { \int_eval:n { \l__randints_max_int - \l__randints_min_int + 1 } } % compute available slots for uniqueness \int_set:Nn \l__randints_slots_int { \l__randints_range_len_int } \bool_if:NTF \l__randints_unique_bool { \bool_if:NTF \l__randints_nonzero_bool { \int_set:Nn \l__randints_slots_int { \int_eval:n { 2 * \l__randints_range_len_int } } \int_compare:nNnT { \l__randints_min_int } <= { 0 } { \int_compare:nNnT { \l__randints_max_int } >= { 0 } { \int_set:Nn \l__randints_slots_int { \int_eval:n { \l__randints_slots_int - 2 } } } } } { \int_set:Nn \l__randints_slots_int { \l__randints_range_len_int } } \int_compare:nNnTF { \clist_count:n {#5} } > { \l__randints_slots_int } { \PackageError{exam}{Not~enough~unique~integers}{Requested~more~unique~integers~than~available~in~range.} } { \clist_clear:N \l__randints_used_clist } } { \clist_clear:N \l__randints_used_clist } % Generate for each bare name and define \name globally \clist_map_inline:nn { #5 } { \bool_if:NTF \l__randints_nonzero_bool { % \pm nonzero: sign * magnitude (support unique/starred) \bool_if:NTF \l__randints_unique_bool { \__randints_pick_unique_signed:nn { \l__randints_min_int } { \l__randints_max_int } \cs_gset:cpn { ##1 } { \int_to_arabic:n { \l_tmpa_int } } \tl_set:Nx \l_tmpa_tl { \int_to_arabic:n { \l_tmpa_int } } \clist_put_right:Nn \l__randints_used_clist { \l_tmpa_tl } } { \cs_gset:cpn { ##1 } { \int_eval:n { ( \int_rand:nn {0}{1} * 2 - 1 ) * \int_rand:nn { \l__randints_min_int } { \l__randints_max_int } } } } } { % Plain integer in [min,max] or unique selection if starred \bool_if:NTF \l__randints_unique_bool { % pick a unique random value via recursion \__randints_pick_unique:nn { \l__randints_min_int } { \l__randints_max_int } \cs_gset:cpn { ##1 } { \int_to_arabic:n { \l_tmpa_int } } \tl_set:Nx \l_tmpa_tl { \int_to_arabic:n { \l_tmpa_int } } \clist_put_right:Nn \l__randints_used_clist { \l_tmpa_tl } } { \cs_gset:cpn { ##1 } { \int_rand:nn { \l__randints_min_int } { \l__randints_max_int } } } } } } \ExplSyntaxOff% The issues I'm running into are that prg_do_while does not actually exist. The other recommendation that Co-Pilot had was to do a recursive call, but this seems like a worse idea. So, my questions are: What is the syntax for the while loop? How should I write this code? Am I over-complicating this whole problem? EDIT Based on @David Carlisle's and @egreg's suggestions, I came up with the following code: \ExplSyntaxOn \NewDocumentCommand \newrandInts { s o D<>{\randIntLower} D(){\randIntUpper} m O{1} }{ % \randInts[nz?]<min>(max){name1,name2,...}[t] % - [nz]: produce pm(magnitude), where magnitude in [min,max] % - <min> and (max) are *separate* optional delimited args; defaults are 1 and 5 % - clist of names; defines \name globally to the drawn integer % - optional randInt multiplier t (defaults to 1) \tl_clear_new:N \l__my_number_tl \seq_clear_new:N \l_numbers_seq \tl_if_eq:nnT {#2} {nz}{ \int_step_inline:nnn {-#4}{-#3} { \seq_put_right:Nn \l_numbers_seq { \fp_eval:n{ ##1 * #6 } } } } \int_step_inline:nnn {#3}{#4} { \seq_put_right:Nn \l_numbers_seq { \fp_eval:n{ ##1 * #6 } } } \seq_shuffle:N \l_numbers_seq \clist_map_inline:nn { #5 } { \IfBooleanTF{#1}{ \seq_pop_left:NN \l_numbers_seq \l__my_number_tl \cs_gset:cpx { ##1 } { \tl_use:N \l__my_number_tl } }{ \cs_gset:cpx { ## 1 } { \seq_rand_item:N \l_numbers_seq } } } } \ExplSyntaxOff I use the code like this: \newrandInts*[nz]{a,b,c,d}[3] \a, \b, \c, \d % prints nonzero random integers between -5 and 5 % multiplied by 3 without repeats: % -3, -9, 3, -6 \newrandInts{a,b,c,d}[0.1] \a, \b, \c, \d % prints random integers between 1 and 5 % multiplied by 0.1 with repeats possible: % 0.3, 0.5, 0.4, 0.1 The multiplication by a scalar was a bit of an afterthought because my current workflow is define random integers, then scale them up.

I am trying to represent a JSON in my document which for documentation purpose has french descriptions inside of strings (which I would like to keep here as the "placeholders" they are). But I don't exactly understand how the string coloring works in listings(utf8) and it seems to move all the accents to the beginning of their words, which isn't ideal. Here's a "minimal" "working" example \documentclass[11pt]{article} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{xcolor} \usepackage{listingsutf8} \lstset{ inputencoding=utf8, extendedchars=\true, showstringspaces=false, } % The code for JSON is copied from https://gist.github.com/ed-cooper/1927af4ccac39b083440d436d018d253 % obviously I don't understand it fully, and the documentation of listings says absolutely nothing about how coloration of strings work (which is the problem here) \definecolor{jsondelim}{RGB}{20,105,176} \definecolor{jsonnumb}{RGB}{106, 109, 32} \definecolor{jsonstring}{rgb}{0.64,0.08,0.08} \lstdefinelanguage{json}{ numbers=left, numberstyle=\small, frame=single, rulecolor=\color{black}, showspaces=false, showtabs=false, breaklines=true, postbreak=\raisebox{0ex}[0ex][0ex]{\ensuremath{\color{gray}\hookrightarrow\space}}, breakatwhitespace=true, basicstyle=\ttfamily\small, upquote=true, morestring=[b]", stringstyle=\color{jsonstring}, literate= *{0}{{{\color{jsonnumb}0}}}{1} {1}{{{\color{jsonnumb}1}}}{1} {2}{{{\color{jsonnumb}2}}}{1} {3}{{{\color{jsonnumb}3}}}{1} {4}{{{\color{jsonnumb}4}}}{1} {5}{{{\color{jsonnumb}5}}}{1} {6}{{{\color{jsonnumb}6}}}{1} {7}{{{\color{jsonnumb}7}}}{1} {8}{{{\color{jsonnumb}8}}}{1} {9}{{{\color{jsonnumb}9}}}{1} {\{}{{{\color{jsondelim}{\{}}}}{1} {\}}{{{\color{jsondelim}{\}}}}}{1} {[}{{{\color{jsondelim}{[}}}}{1} {]}{{{\color{jsondelim}{]}}}}{1} } % --- end of copied json \begin{document} \begin{lstlisting}[language=JSON] "A string with accents - Du texte accentué - Note that accents move to the beginning of a word - Le déplacement des accents est avéré" \end{lstlisting} \end{document} It displays the string somewhat properly (in "red"), except the accents are (a) in front of their respective words (b) in black : Do any one have experienced this and has got ideas ?
