I have searched for various ways to colorize text that appears in Terminal. In general, they fail miserably with lualatex (and may also fail with others, but I did not check). When I first posted this question, I showed a MWE that partially worked. Thanks to Marcel's comment, I realized that I had mingled Lua and TeX syntax, so that MWE could fail. This is a revised MWE that works well. Since others have asked this question, I provide the good MWE now: \documentclass{article} %% compile with lualatex %% Usage: \directlua{terminal_color("N", "Message")} %% Where N is the terminal color code, such as 32 for green. \directlua{ function terminal_color(color_code, text) texio.setescape(0) texio.write_nl("\string\x1B[" .. color_code .. "m" .. text .. "\string\x1B[0m") texio.setescape(1) end }%% \begin{document} \directlua{texio.write_nl("This terminal text is normal color.")} \directlua{terminal_color("32", "This terminal text is green.")} \directlua{texio.write_nl("Normal terminal color.\string\nReally.")} %% Works. \end{document}

I have included the full document because the behaviour only occurs in this context. In the final \multicolumn row of the table, I am constructing a row that visually consists of several fixed-width boxes separated by vertical rules. I want only the first box in that row to have a background colour, with: a consistent row height, the colour filling the box exactly (no padding), the colour reaching the vertical rule, and no colour bleed into adjacent boxes. At the moment, attempts to enforce row height using struts or rules either do not affect the height or cause alignment/bleed issues when combined with colour. What is the correct and robust way to colour only the first fixed-width box in this kind of composite table row while maintaining consistent height and clean rule alignment? (I am open to restructuring the table if there is a better construction.) % !TeX program = xelatex % !TeX spellcheck = en_GB \documentclass[12pt,addpoints]{exam} % ----------------------------- % Maths % ----------------------------- \usepackage{amsmath, amssymb} \usepackage{bm} % ----------------------------- % Graphics & layout % ----------------------------- \usepackage{graphicx} \usepackage{float} \usepackage{pdfpages} \usepackage{geometry} \usepackage{parskip} \usepackage{multicol} % ----------------------------- % TikZ / plots (kept, but minimal) % ----------------------------- \usepackage{tikz} \usetikzlibrary{math, calc} \usepackage{pgfplots} \usepackage{tkz-base} \usepackage{tkz-euclide} \usepackage{tikz-3dplot} \usepackage{tikzlings} \usepackage{tikzpeople} \usepackage{geometry} % ----------------------------- % Fonts (LuaLaTeX) % ----------------------------- \usepackage{fontspec} \setmainfont{Aptos} \usepackage{unicode-math} \setmathfont{Cambria Math} % ----------------------------- % Tables & colour % ----------------------------- \usepackage{xcolor} \usepackage{array} \usepackage{colortbl} % ----------------------------- % Exam class configuration % ----------------------------- \marksnotpoints \qformat{\textbf{Task \thequestion\hfill (\thepoints)}} % ----------------------------- % Page geometry & header % ----------------------------- \newgeometry{ left=2.25cm, right=2cm, top=1.4cm, bottom=0cm } % ----------------------------- % Utility commands % ----------------------------- \newcommand{\uline}[1]{\rule[0pt]{#1}{0.4pt}} \newcommand\dunderline[3][-1pt]{% \sbox0{#3}% \ooalign{\copy0\cr\rule[\dimexpr#1-#2\relax]{\wd0}{#2}}% } \renewcommand{\arraystretch}{2} \newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}} % ----------------------------- % Footer % ----------------------------- \footer{}{\textbf{End of Questions}}{\scriptsize Page \thepage\ / \numpages} \firstpagefooter{}{}{} \extraheadheight[20pt]{20pt}% addded <<<<<<<<<<<<<<<<<< \definecolor{wordgrey}{RGB}{166,166,166} \usepackage[table]{xcolor} \hyphenpenalty=10000 \exhyphenpenalty=10000 \begin{document} \renewcommand{\arraystretch}{1.8} \setlength{\arrayrulewidth}{1pt} \vspace*{-0.25cm} \noindent \setlength{\arrayrulewidth}{0.5pt} \noindent\hspace*{-0.19cm} \begin{tabular}{|p{3.7cm}|p{12.8cm}|} \hline \fontsize{12pt}{14pt}\selectfont\textbf{Something} & Something \\ \hline \fontsize{12pt}{14pt}\selectfont\textbf{Something} & Something \\ \hline \fontsize{12pt}{14pt}\selectfont\textbf{Time Allowed} & \\ \hline \fontsize{12pt}{14pt}\selectfont\textbf{Something} & \\ \hline \fontsize{12pt}{14pt}\selectfont\textbf{Something } & {\fontsize{11}{13}\selectfont \setlength{\labelsep}{1.7em} \setlength{\leftmargini}{3.6em} \begin{itemize} \item One \item \item \item \item \item \item \end{itemize} } \\ \hline \textbf{Something} & \cellcolor{wordgrey} \fontsize{11pt}{13pt}\selectfont \textbullet\ \hspace{0.4cm} Section \\ \cline{2-2} & \fontsize{11pt}{13pt}\selectfont \textbullet\ \hspace{0.4cm} Section \\ \cline{2-2} \hline \textbf{\mbox{ Something}} & \fontsize{11pt}{13pt}\selectfont \textbullet\ \hspace{0.4cm} \\ \hline \multicolumn{2}{|l|}{\hspace*{3.95cm}\fontsize{12pt}{14pt}\selectfont [ something]} \\ \hline \multicolumn{2}{|l|}{% \fontsize{11pt}{13pt}\selectfont \colorbox{wordgrey}{\makebox[3.0cm][l]{\textbf{1.

I have a table spanning multiple pages, and it shall have textwidth. So I chose xltabular (to leverage the advantages of tabularx and longtable [note: the number of columns p1, p2, ... is variable in the original]). (And yes, I also need pgfplotstable in the end.) The question is: Is there a simple way to make all the subtables have textheight? Therefore, the distance to the footer should be increased accordingly. Note: I set paperheight=58mm to better illustrate the problem. \documentclass[paper=a5]{scrreprt} \usepackage[margin=14mm, showframe=true, paperheight=58mm, ]{geometry} \usepackage{pgfplotstable} \pgfplotsset{compat=1.18} \usepackage{xltabular} \newcolumntype{Y}{>{\centering\arraybackslash}X@{\hspace{5pt}}} \begin{document} % Create some table-data ===================== \def\OutFilename{\jobname-data.csv} \newwrite\MyFile \immediate\openout\MyFile=\OutFilename % \foreach[count=\No from 0] \n in {1,...,4}{%% \foreach \k in {0,...,\n}{ \immediate\write\MyFile{\n, \k, 0.1111, 0.2222, 0.3333, 0.4444, 0.5555, 0.6666, 0.7777, \k, \No} }%% } \immediate\closeout\MyFile % =================================== \noindent% \pgfplotstabletypeset[ precision=4, skip 0.,% number format header=true, font=\footnotesize, column type=, begin table=\begin{xltabular}{\textwidth}{c c | *{7}{Y} | c l}, end table=\end{xltabular}, col sep=comma, every head row/.style={%% output empty row, before row={% %% Very first Header ======================== \hline n & k & p1 & p2 & p3 & p4 & p5 & p6 & p7 & k & N \\ \hline \endfirsthead %% Header for subsequent pages ================ \hline n & k & P1 & P2 & P3 & P4 & P5 & P6 & P7 & k & N \\ \hline \endhead %% Footer for all pages except last ================ \hline n & k & q1 & q2 & q3 & q4 & q5 & q6 & q7 & k & N \\ \hline \endfoot %% Footer for the very last page ================ \hline n & k & Q1 & Q2 & Q3 & Q4 & Q5 & Q6 & Q7 & k & N \\ \hline \endlastfoot },% end of 'before row' %% },%% end of 'every head row/.style' %% ]{\OutFilename} \end{document}

Good afternoon everyone, I'd like to know how I can make this figure in Tikz, as I want to learn.

The question is similar to this solution, but not the same: \documentclass[tikz, border=1cm]{standalone} \usetikzlibrary{decorations.pathreplacing} % https://tex.stackexchange.com/a/572738/322482 \begin{document} \begin{tikzpicture}[ rounded corners=1pt, path decomposition/.style={% postaction={decoration={show path construction, lineto code={ \draw[#1] (\tikzinputsegmentfirst) -- (\tikzinputsegmentlast); }, curveto code={ \draw[#1] (\tikzinputsegmentfirst) .. controls (\tikzinputsegmentsupporta) and (\tikzinputsegmentsupportb) ..(\tikzinputsegmentlast) ; }, closepath code={ \draw[#1] (\tikzinputsegmentfirst) -- (\tikzinputsegmentlast) {closepath};} } ,decorate}}] \draw[line cap=round, black, double=gray!10, thick, path decomposition={black, double=gray!10,thick}] (3,3) -- (1,1) -- (3,1) -- (1,3); % here below is what I want with only one path \begin{scope}[xshift=3cm] \draw[black, double=gray!10, thick, line cap=round] (3,3) -- (1,1) -- (1.5,1); \draw[black, double=gray!10, thick, line cap=round] (2.5,1) -- (3,1) -- (1,3); \draw[black, double=gray!10, thick] (1.3,1) -- (2.7,1); \end{scope} \end{tikzpicture} \end{document}

Good day, thank you very much for taking the time to read this. I am working on a mathematics book for high school students, which is quite extensive (between 500 and 1000 pages). The project contains numerous equations and graphics using TikZ, annotate-equations, etc. My goal is to speed up the compilation time. My workflow is based on Windows, MiKTeX with Perl, VS Code with LaTeX Workshop, and LuaLaTeX with latexmk. To accelerate the compilation, I am using the memoize package, which externalizes not only graphics but also equation environments like align, etc. However, I am facing the following issues: Memoize does NOT externalize starred equation environments such as \begin{equation*}, \begin{align*}, etc. Only the unstarred versions (\begin{equation}, \begin{align}) appear as externalized. The displaymath environment [ ... ] is not being taken into account for externalization. In the actual project, I get a huge number of .memo files without their corresponding PDFs, which suggests that the externalization process is not being completed. What could be the problem? How should memoize be correctly configured? How can I ensure that all starred equation environments, including the displaymath [ ... ] shorthand, are properly externalized? \documentclass{book} \usepackage{docmute} \usepackage{memoize} \mmzset{ memo dir=Chapters/main, auto={tikzpicture}{memoize}, auto={tcolorbox}{nomemoize}, auto={mynote}{nomemoize}, % Entornos estándar y amsmath auto={displaymath}{memoize, capture=vbox}, auto={equation}{memoize, capture=vbox}, auto={eqnarray}{memoize, capture=vbox}, auto={align}{memoize, capture=vbox}, auto={gather}{memoize, capture=vbox}, auto={alignat}{memoize, capture=vbox}, auto={multline}{memoize, capture=vbox}, auto={flalign}{memoize, capture=vbox}, } \usepackage{tikz} \usepackage{tcolorbox} \usepackage{amsmath, amssymb, amsthm} \begin{document} Document Body ... \begin{align} a + b & = c \\ d + e & = f \quad \text{Align environment NOT (*)} \end{align} \begin{align*} 5x + 6y & = -55m \\ -9z + 2w & = -99n \quad \text{Align environment with (*)} \end{align*} \begin{equation} -5x^2+4y^2=-3 \quad \text{Equation environment with NOT (*)} \end{equation} \begin{equation*} -5x^2+4y^2=-3 \quad \text{Equation environment WITH (*)} \end{equation*} \[ y=mx+b \quad \text{Display Math environment } \] \begin{multline} y=-4x^2+8x+8+4444444444 \quad \text{Multline environment NOT (*)} \end{multline} \begin{multline*} y=-8x^2+8x+8+8888888888 \quad \text{Multline environment WITH (*)} \end{multline*} \end{document} I would greatly appreciate any help you can provide.

Simple (I hope) question. Does not need MWE. I use LuaLaTeX, although I expect that this question is generally applicable. If a font does not have a requested Unicode character, does (Lua)LaTeX insert a .notdef glyph there, or does it insert U+FFFD (if the font has U+FFFD) ? Does this depend on circumstances (such as math/text mode, etc.) ? I am not worried about intentionally contrived situations that would never occur in a real document. Reason I ask: I design and use my own fonts, which have U+FFFD. Since this is a valid Unicode location, I can do font-related tricks with it, such as using OpenType features to show different glyphs, depending on the problem. But I cannot do them with .notdef, because it is not a valid Unicode location. I dimly recall reading (here at SE) that U+FFFD is used, if found, but I cannot find that thread. Search returns XeTeX-specific info, and I do not use that.

I have a collection of xsim exercises, each of which has a solution and shortsolution implemented. In my exercises-collection document, I want to print the solutions or shortsolutions (depending on a toggle) chapter by chapter (or section by section). To define the shortsolutions, I mainly use the definition from the xsim-manual: % new property: \DeclareExerciseProperty{shortsolution} % new environment: \NewDocumentEnvironment{shortsolution}{+b} {% \edef\ExerciseType{\csname g_xsim_exercise_type_tl\endcsname}% \edef\ExerciseID{\csname g_xsim_exercise_id_tl\endcsname}% \SetExerciseProperty{shortsolution}{#1}% } {} % we'll use a description list for the list of short solutions: \newcommand\printshortsolutions{% \begin{description} \ForEachUsedExerciseByType{% \GetExercisePropertyT{shortsolution} {\item[Short Solution ##3]####1}% }% \end{description} } While \printsolutions[chapter={true}] works as expected, the option \printshortsolutions[chapter={true}] unfortunately does not work. Here, the short solutions of all chapters are printed every time.

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 am using LuaLaTeX together with tcolorbox and the new lualineno package. The intended behaviour is to apply line numbering exclusively to the upper part of a tcolorbox (the box body), while leaving the title unaffected. With the minimal example below, line numbering behaves differently depending on whether the box has a title. \documentclass{article} \usepackage{tcolorbox} \usepackage{pgffor} \usepackage{lualineno} \newcounter{lineno} \lualineno{% define = { name = default toks = {\stepcounter{lineno}} left = {\tiny\thelineno \kern.8em} } } \begin{document} Some text before the box. \begin{tcolorbox}[ % title = Test, before upper = {\lualineno{set = default}}, after upper = {\lualineno{unset}} ] \foreach \n in {1,...,30}{ \noindent This is line \n. \\ } \end{tcolorbox} Some text after the box. \end{document} Observed behavior: Without a title (title commented out): Line numbers appear correctly outside the box. With a title (title = Test uncommented): Line numbers disappear. No compilation error or warning is produced. If the box is made breakable, I observe a related but slightly different effect: with a titled breakable box, line numbers disappear in the first segment of the box (before the page break). Adding a title should not affect line numbering inside the box. I would expect identical numbering behavior with or without a title. Is this interaction between tcolorbox and lualineno expected? Should lualineno be applied differently when titles are used? Any explanation of the underlying mechanism or guidance on proper usage would be greatly appreciated.

I have code sections in my text that are highlighted with lstlisting. The line breaks are working and I get a (desired!) \hookrightarrow int the output text. So from this input TeX: My code: \begin{lstlisting} This is a long long long long long long long long long long long long long long long long long long line of code \end{lstlisting} I get this in the output PDF: Now I want to be able to copy and paste the code from the PDF to an editor. I was able to follow https://tex.stackexchange.com/a/649475/243557 to remove the (desired!) \hookrightarrow with the help of \usepackage{accsupp} from the clipboard on text copy. But the line break is still in the text. So if I copy+paste the above code from the PDF to my editor of choice I get the following result (works with Adobe Acrobat Reader): Note the line of code and the LF. Now my idea was to use the ANSI escape code for backspace in the ActualText={} of postbreak=\raisebox{0ex}[0ex][0ex]{\BeginAccSupp{ActualText={<BS-char-here>}}\ensuremath{\color{gray}\hookrightarrow\space}\EndAccSupp{}}, to somehow delete the line break from the clipboard text. I added the non visible BS-code directly but this did not result in the desired outcome (did not build). I also don't want to delete all line breaks just the ones that were added by lstlisting. Is this the right way to go or could I use some other technique to do the job. Notes: Code in a parallel documents is unfortunately not an option. Its a big PDF file with different code snippets. Furthermore, the PDF is our only allowed "source of truth". I know that the PDF reader plays an important role in this matter. But I'm fine if it is working with Adobe. Edit: Here is my listings setup: \documentclass{article} \usepackage{xcolor} \usepackage{listings} \usepackage{accsupp} \lstset{ % Highlight line break due to textwidth % https://tex.stackexchange.com/questions/116534/lstlisting-line-wrapping postbreak=\raisebox{0ex}[0ex][0ex]{\BeginAccSupp{ActualText={}}\ensuremath{\color{gray}\hookrightarrow\space}\EndAccSupp{}}, breakatwhitespace = true, breaklines = true } \begin{document} My code: \begin{lstlisting} This is a long long long long long long long long long long long long long long long long long long line of code \end{lstlisting} \end{document} In a previous version I hat the input as Markdown. This is because I use Pandoc to convert to TeX and then to the PDF file. But the first step is not important for this problem and I replaced the Markdown with the converted TeX-Input.

I'm trying to make a CV based on this Overleaf template.

I normally use memoir to print my books. I am now editing a scholarly journal. Can I use memoir for this task? The main problem seems to redefine author for each chapter, Bibliography is at the end, I prefer a comprehensive list at the end of the journal. I saw the proc class but memoir seems much more developed.

Easy as that. biblatex-philosophy capitalizes all names, including the von-part, though, depending on the language, only some of them should be capitalized, and then, I want to choose it by myself. @Article{DeCampos:Unwritten, author = {de Campos, Rogério G.}, % "de" is to be omitted from sorting, should be wrtten in small letters sortname = {Campos, Rogério G.}, title = {Dotrinas I-don't-know}, langid = {brasilian}, journaltitle = {Peitho}, date = 2022, volume = 13, pages = {185-198}} versus @Article{DiBrasi:Brasilicata, author = {Di Brasi, Brasiliero}, title = {Dottrina Brasiliana}, langid = {italian}, journaltitle = {Brasilicata}, date = 2024, volume = 2, pages = {7-49}}

I am trying to draw lines around a number of nodes. I very much like the definition of \convexpath definition given here, but it is not working well on my setup (MacTex 2014 with all available updates). I tried to compile Claudio Fiandrino's first solution, but what I get is the following, which is clearly not what I should be getting. Any ideas would be much appreciated.

When I need to write a sequence of dots without using TikZ, I often define a simple macro based on \bullet or another symbol that produces two or three dots (which they can be increase and decrease in size). However, I would like to generalize this idea so that I can obtain a sequence of n dots (horizontal, diagonal, vertical). In particular, I would like the solution I define to work well in different mathematical contexts: a sequence of dots arranged horizontally on a line, a vertical sequence for example under a brace or associated with \vdots, and even a diagonal arrangement for something like \ddots. I would also like this sequence of dots to automatically adapt to different math style sizes, meaning it should work properly in \displaystyle, \scriptstyle, \scriptscriptstyle, etc. Ideally, it should be possible to scale the symbols elegantly using packages like scalerel or equivalent techniques, so that the macro can be used in subscripts, superscripts, or expressions of different sizes without visual issues. Another requirement is that these sequences of dots should be able to be grouped in pairs, triplets, quadruplets, etc., and that such groups can be represented under a brace or curly bracket to visually highlight those groupings within the formulas. The goal is to have a parameterized macro that generates an arbitrary sequence of dots with uniform spacing and consistent behavior in various mathematical contexts, simple to use and not dependent on TikZ or other packages. Is there a well-established way to approach this problem? \documentclass{article} \usepackage{mathtools,amssymb} \newcommand{\Dots}[1]{% \mathpunct{\ifnum#1>0 \cdot\fi}% \ifnum#1>1 \mathpunct{\cdot}\fi% \ifnum#1>2 \mathpunct{\cdot}\fi% \ifnum#1>3 \mathpunct{\cdot}\fi% \ifnum#1>4 \mathpunct{\cdot}\fi% \ifnum#1>5 \mathpunct{\cdot}\fi% } \begin{document} $a\Dots{1}b$ $\Dots{2}$ $\Dots{3}$ $\Dots{4}$ $\Dots{6}$ \end{document} Something like this where the size of the bullet can be changed:

I found this post and I'm trying to retrieve the version shown in the image below. Does anyone know how I can get that specific version?

I have a full TeX Live installation with latest packages. Some packages I use have github or gitlab repositories. Sometimes I write small fixes in my preamble for some packages. I'd like to submit them back to the git repos of the packages, so that they can be merged and released on CTAN, for other to benefit from the fixes. For my own local documents I just git init and commit/push to my private repos, that's easy. But for fixes for \usepackage packages (or classes): should I just go to my /usr/local/texlive/... folder and do a git init in the package folder to be able to push to my personal remote github/gitlab account and open a pull request to the main repository? This doesn't feel right as it pollutes the TeX Live installations. I could copy-paste the whole package somewhere else and include it in my documents (for testing and directly using my changes) - but then I don't use the official version from TeX Live anymore and maybe miss other important releases. And I also have to copy-paste stuff around - uncomfortable, error-prone. How do other people comfortably contribute to 3rd party packages without polluting the local TeX installation or their own documents, and avoiding endless copy-paste situations? Disclaimer: this question is not about how to use git or upload directly to CTAN! I'd like to know how I can comfortably contribute to existing packages that have public git repositories and are maintained by someone on CTAN already.

So, I've chosen \newcolumntype{Y}{>{\centering\arraybackslash}X} for them. The rest are c-columns.

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.

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.
