I have some lua code that generates coordinates of many triangles/quadrilaterals I then want to draw/fill. See this answer about Penrose tilings for a concrete example. The drawing is actually done in TikZ via the luadraw package, but I am wondering if I can make the code faster by replacing TikZ with l3draw. Rewriting my actual code to remove TikZ and luadraw dependences (and use l3draw or any other drawing tool) is not a complex task, but will ask me some time due to my limited programming skills. So I would prefer to know in advance if this is a good idea or not. Apart possibly performance, is there any other reasons to use l3draw over pgf for this kind of task?

Consider this MWE: \documentclass{article} %\usepackage{luadraw} % Un-comment this line to get an error \usepackage[executable=python]{pyluatex} % May need to substitute: % \usepackage[executable=python3]{pyluatex} % \usepackage[executable=python.exe]{pyluatex} % (Or whatever works on your system) \begin{document} ok \end{document} The above compiles fine for me (using LuaLaTeX, with the --shell-escape option, from a TeXLive distribution in Windows 11 Enterprise). I get a document showing the text "ok" (without the quotes), as expected. However, if I uncomment the usepackage{luadraw} line, then I get an error: This is LuaHBTeX, Version 1.24.0 (TeX Live 2026) system commands enabled. (./test100.tex LaTeX2e <2025-11-01> L3 programming layer <2026-03-20> (c:/texlive/2026/texmf-dist/tex/latex/base/article.cls Document Class: article 2025/01/22 v1.4n Standard LaTeX document class (c:/texlive/2026/texmf-dist/tex/latex/base/size10.clo)) ... ...

Note: if I uncomment the \usepackage{luadraw} and put it after the \usepackage{pyluatex}, then it actually does compile without error. However, if I then replace the ok with something that uses pyluatex, like \py{'ok'}, then I get another error. So simply switching the loading order does not really solve the issue. Note: I recently (April 29, 2026) ran tlmgr update --all, and also re-installed a current version (version 2.8) of luadraw (using l3build install as described at https://github.com/pfradin/luadraw). Question: Is it possible to use both pyluatex and luadraw together in one document? Secondary question: Is this a bug, and if so, is there one package that is at fault? I would be happy to file a bug report somewhere if that is appropriate. Neither package seems to cause problems for me on its own; it is only when both are loaded that I am experiencing a problem.

I want to automatically create an author's index and I'm not sure what I doing wrong. I am using TeXShop to compile. My file will compile in Latex with no errors.

I should create a drawing that illustrates this domain in 3D: T= \{(x, y, z) \in \mathbb{R}^3\colon x^2 +y^2\leq (z-9)^2, 0\leq z\leq 3 \}. It is a double cone with vertex at (0,0,3) if it were x^2 +y^2= (z-9)^2. I may have to change the scale but I don’t want the drawing to look worse. How can I colour the two-sloped cone part that satisfies the inequality x^2 +y^2\leq (z-9)^2? ...and then adding 0\leq z\leq 3? \documentclass{article} \usepackage{tikz} \usetikzlibrary{patterns} \usepackage{tikz-3dplot} \usepackage[active,tightpage]{preview} \PreviewEnvironment{tikzpicture} \setlength\PreviewBorder{2pt} \begin{document} \tdplotsetmaincoords{60}{110} \begin{tikzpicture}[tdplot_main_coords,scale=0.9] \pgfmathsetmacro{\tini}{0.5*pi} \pgfmathsetmacro{\tfin}{1.85*pi} \pgfmathsetmacro{\tend}{2.5*pi} \def\h{10.2} \draw[thick,->] (0,0,0) -- (3.5,0,0) node[below left] {$x$}; \draw[dashed] (0,0,0) -- (-2.5,0,0); \draw[thick,->] (0,0,0) -- (0,3.5,0) node[right] {$y$}; \draw[dashed] (0,0,0) -- (0,-2.5,0); \draw[thick,->] (0,0,0) -- (0,0,12) node[above] {$z$}; \fill (0,0,9) circle (1pt); \node[right] at (0,0,9) {$(0,0,9)$}; \foreach \angulo in {0,2,...,358}{ \draw[cyan,very thick,opacity=0.12,rotate around z=\angulo] plot[domain=0:2,smooth,variable=\t] ({0},{\t},{9 + \t}); \draw[cyan,very thick,opacity=0.12,rotate around z=\angulo] plot[domain=0:2,smooth,variable=\t] ({0},{\t},{9 - \t}); } \foreach \z in {7.6,7.8,...,10.4}{ \pgfmathsetmacro{\r}{abs(\z-9)} \draw[cyan,thick,opacity=0.35] plot[domain=\tini:\tfin,smooth,variable=\t] ({\r*cos(\t r)},{\r*sin(\t r)},{\z}); } \foreach \z in {7.6,7.8,...,10.4}{ \pgfmathsetmacro{\r}{abs(\z-9)} \draw[cyan,thick,opacity=0.35] plot[domain=\tfin:\tend,smooth,variable=\t] ({\r*cos(\t r)},{\r*sin(\t r)},{\z}); } \pgfmathsetmacro{\r}{abs(\h-9)} \draw[red,very thick] plot[domain=0:360,smooth,variable=\t] ({\r*cos(\t)},{\r*sin(\t)},{\h}); \node[red, above right] at ({\r},0,\h) {$z=h$}; \fill[yellow,opacity=0.35] plot[domain=0:360,smooth,variable=\t] ({\r*cos(\t)},{\r*sin(\t)},0); \draw[red,thick] plot[domain=0:360,smooth,variable=\t] ({\r*cos(\t)},{\r*sin(\t)},0); \foreach \angle in {0,45,...,315}{ \pgfmathsetmacro{\x}{\r*cos(\angle)} \pgfmathsetmacro{\y}{\r*sin(\angle)} \draw[gray,dashed,opacity=0.5] (\x,\y,0) -- (\x,\y,\h); } \node[blue,right] at (0,0,11.5) {$x^2 + y^2 = (z-9)^2$}; \end{tikzpicture} \end{document}

I want to implement given formatting requirements, however, I feel overwhelmed by the number of parameters and their dependencies, and, thus, I don't know which to begin with, as I feel like all of them need to be considered simultaniously. Furthermore, there are even more formatting requirements to fulfill, yet, the following should be the most essential ones, which is why I want to implement these first and condensed them in a table: I use the KOMA-script class scrreprt and would have used the parskip=full- option to seperate paragraphs from each other. If there is any info missing, please tell me and I'll provide it. And if some requirement seems odd, please also let me know. Thanks in advance!

I have created a custom ⍟ symbol using TikZ, which works well, except that it ignores the colour of the surrounding text. MWE: \documentclass{article} \usepackage{tikz} \usepackage{scalerel} \newsavebox{\whitecircstar}\sbox{\whitecircstar}{\kern.075em\tikz{\node[draw, circle,line width=.36pt, inner sep=0]{$*$};}\kern.075em} \newcommand{\ostar}{\mathbin{\scalerel*{\usebox{\whitecircstar}}{\odot}}} \begin{document} \textcolor{red}{Before $\ostar$ After} \end{document} Output: How can I make \ostar the same colour as the surrounding text? My understanding was that . was a special symbol for the current colour in xcolor, but adding color=. to the node arguments had no effect.

I am a Windows 10 user with MiKTeX installed. Today I installed VS Code and added LaTeX Workshop. I noticed the pdf viewer in VS Code (that I use to see the compiled pdf file from my LaTeX project) has already defined shortcuts. By experimentation, they seem to coincide with those of the mozilla firefox pdf viewer (this list is not exhaustive), but I cannot find an official vscode's nor LaTeX Workshop's shortcut list for the pdf viewer (I cannot find anything in VS Code's nor LaTeX Workshop's settings). My two questions are: Q1. Where can I find such a list? Q2. Is there a way to edit the shortcuts of the VS Code pdf viewer? It happens that the VS Code pdf viewer uses Alt + LeftArrow (resp., Alt + Rightarrow) to jump to previous position (resp., forward position); for example, this is useful when using internal pdf links. However, these shortcuts are also used by VS Code navigation. (Answering to anyone who thinks this question should rather be in Stack Overflow rather than in TSE: The pdf viewer is really managed by LaTeX Workshop, not VS Code, it syncs the pdf file with the .tex file via SyncTeX.) EDIT: After several prompts in the Stack Overflow AI Assist (henceforth SOAIA), it proposed to deactivate alt+left and alt+right for VS Code internal navigation while the LaTeX Workshop pdf viewer is active (so that only the latter detects the keybinding). This seems reasonable. To achieve this, one has to edit the keybindings.json file and add: [ { "key": "alt+left", "command": "-workbench.action.navigateBack", "when": "activeWebviewPanelId == 'whatever-latex-workshop-pdf-viewType-is'" }, { "key": "alt+right", "command": "-workbench.action.navigateForward", "when": "activeWebviewPanelId == 'whatever-latex-workshop-pdf-viewType-is'" } ] So now we need to find whatever-latex-workshop-pdf-viewType-is. I cannot find this. SOAIA is telling me to run the commands Developer: Toggle Keyboard Shortcuts Troubleshooting or Developer: Toggle Developer Tools to find out the correct viewType but I don't one what with it once run.

My goal is to get a rectangle like the one below, but with text in the nested rectangles. Line types could be for example the following: I saw tikz: Multiple splits of rectangle, but it does not answer the question on the line types. Beyond that, I am a beginner using Tikz, and I'd like the answer explained, since the linked answer is complex to understand. Thanks!

Not sure what is wrong with my minipage figures, this is the same kind of layout that I have used in the past with no problems, but for some reason now it is not working. I am trying to have all four figures have the same width, with all the captions also aligned on the same line. The following code \documentclass[12pt, a4paper, twoside, openright]{article} \usepackage{graphicx} \usepackage{float} \usepackage{caption} \begin{document} \begin{figure}[h!] \centering \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_1.png} \caption{Quartier 1}\label{fig:q1} \end{minipage}\hfill \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_2.png} \caption{Quartier 2}\label{fig:q2} \end{minipage} \hfill \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_3.png} \caption{Quartier 3}\label{fig:q3} \end{minipage} \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_4.png} \caption{Quartier 4}\label{fig:q4} \end{minipage} \end{figure} \end{document} returns the following result:

I have an issue with the following code, kindly provided by egreg some time ago answer by egreg. It worked well, but I recently noticed an unwanted behavior. I am not sufficiently familiar with expl3 to fix it myself, nor do I fully understand how the code works. \ExplSyntaxOn \NewDocumentCommand{\pc}{m} % projective coordinates { \seq_set_split:NVn \l_tmpa_seq \c_colon_str { #1 } ( \seq_use:Nn \l_tmpa_seq { \mspace{1\medmuskip}{:}\mspace{1\medmuskip} } ) } \ExplSyntaxOff \documentclass{article} \usepackage{amsmath} \begin{document} \[ \begin{aligned} &(a:b:c) & & (1:-1:2) & &\qquad\verb|standard|\\ &\pc{a:b:c} & & \pc{1:-1:3} & &\qquad\verb|with \pc command|\\ &(a:-b:c) & & (1:-2:3) & &\qquad\verb|standard|\\ &\pc{a:-b:c}& & \pc{1:-2:3} & &\qquad\verb|with \pc command| \end{aligned} \] \[ \pc{a,b,c,d}\quad \pc{a;b;c;d,e,f:g:h:i,l} \] \end{document} Here is the output of the minimal working example: The actual issue appears when a coordinate other than the first is negative (for example \pc{a:-b:c} or \pc{1:-2:3}), where the spacing/output differs from the standard notation. As an aside, I also do not understand why commands such as \pc{a,b,c} or \pc{a;b;c:d} produce the output they do. Could someone explain what is happening here, and how to modify the macro so that it behaves correctly in all cases?

This example \hfuzz=10000pt \hsize=0pt \noindent\hskip0pt thirteen --- dimensional \bye is equivalent to \hfuzz=10000pt \hsize=0pt \noindent\hskip0pt thirteen\hskip0pt---\nobreak\hskip0pt dimensional \bye Why in the first case space is equivalent to \hskip0pt and in second case --- to \nobreak\hskip0pt (i.e., why in the second case \nobreak is not needed before space) ? BTW, in the following example if we delete \nobreak before second \space, the breaking decision after --- is changed. \hfuzz=10000pt \hsize=7.29cm \noindent Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

I would like to add a very large picture on a title page, covering the whole page with a large offset (picture pasted to the upper-left side of the page), blended on the page background (below the title, author's name and other text elements), with some transparency effect, and background blending effect. How should we achieve this? The picture is supposed to be partly shown on the page, about half of it showing on the upper-left side, like an "intrusion" on the page (sorry for the bad english description. I hope you get the picture). Here's a MWE to be modified, showing a title page prototype: \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt]{geometry} \usepackage{titlesec} \usepackage{graphicx} \usepackage[dvipsnames]{xcolor} \usepackage{float} \usepackage{fancyhdr} \usepackage[titles]{tocloft} \usepackage{shadowtext} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \frontmatter % Title Page : \begin{titlepage} \definecolor{lightbrown}{RGB}{177, 149, 93} \definecolor{darkbrown1}{RGB}{58, 41, 26} \definecolor{darkbrown2}{RGB}{50, 30, 0} % Frame : \begin{tikzpicture}[remember picture, overlay] \draw[line width = 1in,color = white] ($(current page.north west) + (0.25in,0.25in)$) rectangle ($(current page.south east) + (0.25in,-0.25in)$); \draw[line width = 0.25pt,color = black] ($(current page.north west) + (0.75in,-0.25in)$) rectangle ($(current page.south east) + (-0.25in,0.25in)$); %\draw[line width = 1pt,color = darkbrown1] ($(current page.north west) + (1in,-0.5in)$) rectangle ($(current page.south east) + (-0.5in,0.5in)$); \end{tikzpicture} \shadowoffsetx{2.5pt} \shadowoffsety{3.5pt} \shadowcolor{gray!80} \definecolor{pagetitre}{RGB}{150,120,100} \pagecolor{pagetitre} \centering \vspace*{\baselineskip} \vfill {\textcolor{black}{\fontsize{26}{0}\selectfont\sffamily\textbf{\shadowtext{Some Nice Title Here}}}} \\[2.5\baselineskip] {\textcolor{black}{\huge\sffamily\scshape Someone}} \vfill \vfill \includegraphics[width=11cm]{example-grid-100x100pt} \vfill {\textcolor{black}{\Large\selectfont\sffamily\scshape Some copyright notice}} \end{titlepage} \pagecolor{white} Blabla \end{document} So how can I add a very large picture blended with the page background colour, with some transparency effect, and a large up-left offset? The large picture should fit inside the frame defined with the tikzpicture environment, and stay below all text on the title page.

I am trying to include an image in the center part of the header (between the course name and semester, and the professor's name. I have tried but it keeps moving, or hiding text behind.

in my bibliographies I often have references to older literature in various languages, for which English translations exist, like: @BOOK{Pto-00, AUTHOR = {{{\foreignlanguage{greek}{Κλαύδιος Πτολεμαῖος}} [Klaúdios Ptolemaíos]}}, sortname = {Ptolemaios}, shortauthor = {Ptolemaíos}, TITLE = {{{\foreignlanguage{greek}{μέγιστη σύνταξις}} [megíste sýntaxis] [\textnormal{{\foreignlanguage{arabic}{المجسطي}}} al-maǧisṭī] [Almagest] }}, sorttitle = {Almagest}, YEAR = {2nd Century AD}, address = {Alexandria (EG)}, related = {Pto-84}, relatedtype = {translatedbyas}, langid = {greek}, } @BOOK{Pto-84, AUTHOR = {{{\foreignlanguage{greek}{Κλαύδιος Πτολεμαῖος}} [Klaúdios Ptolemaíos]}}, TITLE = {Ptolemy's Almagest}, translator = {Toomer, G.J.}, editor = {Toomer, G.J.}, YEAR = {1984}, PUBLISHER = {Duckworth}, address = {London (UK)}, url = {https://classicalliberalarts.com/resources/PTOLEMY_ALMAGEST_ENGLISH.pdf}, } Unfortunately, I could not find in the bibLaTeX manual a list of the relatedtype-options (editedby, editedbyas, translatedby...) and their respective use. It would help me to make more effective use of this facility. Does anybody know of such a thing?

I am using the vscodeicons and vectorlogos packages to include small icons in my document. Consider this MWE: \documentclass{article} \usepackage{vscodeicons,vectorlogos} \begin{document} Inline \vscodeicon[filetype]{wolfram} version Geogebra \vectorlogo[icon]{geogebra} \end{document} To my eyes, the icons appear slightly shifted downwards with respect to the surrounding text. Are they already correctly aligned in the packages, or would it be better to tweak them (e.g., with \raisebox or package options such as height=auto/dstrut=false) so that they sit exactly on the baseline like the surrounding text? If some adjustment is recommended, what would be a robust way to align them in inline text without breaking the line spacing?

Any suggestions on how to support such two-sided harpoon arrow with label?

I am typesetting the following matrix equation (MWE): \documentclass[preview]{standalone} \usepackage{iftex} \ifLuaTeX \usepackage{unicode-math} \else \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{amsmath} \fi \begin{document} \[ \begin{pmatrix} \underline{v}_1^T \\ \underline{v}_3^T \\ \underline{v}_3^T \end{pmatrix} = \begin{pmatrix} v_{11} & v_{12} & v_{13} \\ v_{21} & v_{22} & v_{23} \\ v_{31} & v_{32} & v_{33} \end{pmatrix} \] \end{document} When I compile with pdflatex, the matrix elements on the l.h.s. look good to me. In particular, both the subscripts (indices) and the superscripts (T) are properly set and readable: However, when I compile with lualatex, the subscripts overlap with the succeeding line: I've also created a gif for a better comparison: My question is: How can I avoid the overlap? (My wish would be to consistently raise the subscripts. I'd like to avoid increasing the row distance, because then the rows on the l.h.s. would not properly align with the rows on the r.h.s.)

I am working on a personalized CV-class and I have need to add a horizontal header line manually positioned, that not use TikZ and not shift horizontally or vertically text and gray box like the image below I already use a grey background with \AddToShipoutPictureBG \AddToShipoutPictureBG*{% \AtPageUpperLeft{% \raisebox{-.29\paperheight}{% \color{gray!15}\rule{\paperwidth}{.29\paperheight}% }% }% } I have tried \noindent\hrulefill or with \hskip-1em\vtop{\vskip0.5cm\hsize=2in \hrulefill} or \makebox but it does not permit me to create a rule without shift vertically/horizontally text and gray box. Here a minimal working example using another similar class. You can see that the rule \noindent\hrulefill that moves the text downwards: \documentclass[italian,a4paper]{europasscv} \usepackage[italian]{babel} \usepackage{graphicx,array,booktabs,fontawesome6,xcolor,tikz} \usepackage{eso-pic} \DeclareRobustCommand\ebseries{\fontseries{eb}\selectfont} \DeclareTextFontCommand{\texteb}{\ebseries} \ecvname{%\fontseries{b}\selectfont %\textbf{ \sffamily{\ebseries Marco Bellini } %} } \ecvaddress{\!Via delle Rose, 25 40123 Apuleia} \ecvmobile{\,(+39) } \ecvtelephone{(+39) } \begin{document} \AddToShipoutPictureBG*{% \AtPageUpperLeft{% \raisebox{-.29\paperheight}{% \color{gray!15}\rule{\paperwidth}{.29\paperheight}% }% }% } \begin{europasscv} \noindent\hrulefill \sffamily \ecvpersonalinfo{} \ecvbigitem{Posizione ricoperta}{ingegnere} \ecvsection{ingegnere} \ecvtitle{2011 – in corso}{Impresa edile Zante} \ecvitem{}{Bla bla bla} \ecvtitle{2024}{Docente a contratto} \ecvitem{}{Matematica II} \ecvitem{\ecvhighlight{Attività o settore}}{Dipartimento di Scienze Chimiche – Università degli Studi di Modena.} \end{europasscv} \end{document} What is the best way to add a line as per my instructions?

I am using this code in luadraw to cut a sphere with a plane and move one of the cut parts to another position. Currently, the surface of the sphere is not really smooth. If I increase the number in this line local S = sphere(Origin, R, 60, 60) to a larger value, the compilation becomes slower. How can I make the sphere smoother? \documentclass[border=5pt]{standalone} \usepackage[svgnames]{xcolor} \usepackage[3d]{luadraw} \begin{document} \begin{luadraw}{name=sphere_clip3d_fixed} local R = 3 local g = graph3d:new{window={-R-2, R+1, -R-1, R}, viewdir={110, 60}, size={10, 10}} Hiddenlinestyle = "dashed" local S = sphere(Origin, R, 60, 60) local Box = parallelep(M(-5,-5,1.5), 10*vecI, 10*vecJ, 10*vecK) local S_top = clip3d(S, Box) local S_bottom = clip3d(S, Box, true) local vector = 2*vecK + 5*vecJ local S_top_shifted = shift3d(S_top, vector) local I_bottom = border(S_bottom) local I_top_shifted = border(S_top_shifted) g:Dscene3d( g:addFacet(S_bottom, {draw="ball color=orange", color="orange", backcull=true}), g:addFacet(S_top_shifted, {draw="ball color=orange", color="orange", backcull=true}), g:addPolyline(I_bottom, {color="Navy", hidden=true}), g:addPolyline(I_top_shifted, {color="Navy", hidden=true}) ) g:Show() \end{luadraw} \end{document}

Why does the LaTeX example 𝑨 \mathbf{\mathit{A}} become italic but not bold italic font?, or 𝙂 \mathsf{\mathbf{\mathit{G}}} remain sans serif and bold italic? I'd like to use the sans serif italic/bold italic options from the \usepackage{isomath} to represent this. It must have the function of stacking LaTeX math fonts, It would be better to mix and match LaTeX math font formats randomly. For example in font format glyphs display: 𝑨 \mathbf{\mathit} and 𝕬 \mathbf{\mathfrak}/ 𝗔 \mathbf{\mathsf}please use \bm{} + \mathit/\mathfrak/\mathsf in working this command style 𝓐 \mathbf{\mathscr} or 𝓐 \mathscr{\mathbf} please use \pmb{} + \mathscr in working this command style
