I am adding a new feature to circuitikz to simplify the usage of "user-defined" voltages (and currents and "flow"s). The question is not specific to circuitikz, although the MWE is — sorry for the complication. If I manage a smaller MWE I'll post here. The basic question is: when a TikZ \path command is processed (and a \draw, etc., which are basically the same), is it possible to add a hook to be expanded at the end of it? I mean, after the final ; is found. In the following MWE, I would like to add some code to the addcall key so that I do not need to add the final \DoAdvVoltage. Ideally, the macro should be called after each path is finished, but calling it before of the end of the environment wold be acceptable. The solution should be engine-independent (well, it should work in the engines supported by TikZ). \documentclass[12pt]{article} \usepackage[T1]{fontenc} \usepackage[RPvoltages]{circuitikz} % just an example \ctikzset{voltage=raised, !v sym/.style={no v symbols}} \newcommand{\placesigns}[2]{% place the +- signs at a fixed distance \path (#1voltage.center) ++(-\ctikzgetdirection{#1}:0.5cm) node[]{$+$}; \path (#1voltage.center) ++(180-\ctikzgetdirection{#1}:0.5cm) node[]{$-$}; } % add a command queue to circuitikz \makeatletter \gdef\local@voltages{} \def\addcommand#1#2{%add to \commands the macro \#1{nodename}{#2} \begingroup \edef\@@name{\ctikzvalof{bipole/name}} \edef\@@temp{% \noexpand\pgfutil@g@addto@macro\noexpand\local@voltages{% \expandafter\noexpand\csname #1\endcsname {\@@name}{#2}% }% }% \@@temp \endgroup } \def\DoAdvVoltages{\local@voltages\relax\gdef\local@voltages{}} \makeatother % This works, but just for LaTeX (or not?) % Moreover, I'd like to add this from the addcall keys, so that % I don't call it for *every* tikzpicture! % \AddToHook{env/tikzpicture/end}{\DoAdvVoltages} \ctikzset{addmyv/.style = {v={#1}, !v sym, addcall={#1}}} \ctikzset{addcall/.code ={\addcommand{placesigns}{#1}}} \begin{document} \begin{tikzpicture} \draw (3,0) -- ++(1,0) coordinate(Rbot) to[R=R, name=vR, addmyv={$u_R$}] ++(0,+3) -- ++(-1,0); \draw (Rbot) -- ++(2,0) coordinate(Cbot) to[C=C, name=vC, addmyv={$u_C$}] ++(0,+3) -- ++(-2,0); \draw(Cbot) to [L=L, name=vL, addmyv={$u_L$}] ++(2,0); \DoAdvVoltages \end{tikzpicture} \end{document}

I have a long document (600+ pages) that has been using \clearpage and \afterpage to force some page breaks and figure placement, and breakable tcolorboxes as example environments. This document occasionally gets into states where a fresh compile of the document completes without errors, the second compilation fails with ! LaTeX Error: Not in outer par mode. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.128 \clearpage and the third and subsequent compilations succeed. Based on comments on my closed question \clearpage causes "not in outer par mode error" on second pass, I've found ways to reduce the use of \afterpage and to use non-float objects that otherwise behave like figures when I do need \afterpage, and have also tracked down my specific problem to an interaction between Floats in afterpage. Special footnote handling that uses shipout to move the footnote outside of the box. The presence of a long table of contents. (see demonstration code below) -- While I now understand more about what source-code patterns can produce these errors, I would stil like to better understand how the processing of the document leads to the specific error behavior. The error message (and other documentation of when the error is expected to appear) seems to indicate that the compiler is reading a \clearpage command at a point in the document which some internal state variable registers as being inside of a float. Combined with this error appearing on the second pass (when the TOC moves pages around) and its absence if the \tableofcontents call is removed, a parsimonious interpretation would be that either the location of the page breaks forced by \clearpage or the page numbers on which the floats appear are being retained from the previous pass, and so are triggering the error, even though \clearpage command does not appear inside float environment in the source code. Once the page locations have stabilized, the error goes away. Comments on my previous question suggested that this is not the correct model for how the error plays out at compilation time. What is a better way to understand the behavior of these kinds of errors that show up on intermediate compilations, but go away if I compile enough times? -- Code for generating the kind of errors that I'm encountering. This document should compile successfully on the first pass, error three times on the second and third passes, and then compile correctly on subsequent passes. \documentclass[11pt]{book} \usepackage{afterpage} \usepackage[many]{tcolorbox} \tcbuselibrary{magazine} % Not directly relevant here, but gets me a foreach function for the examples %%%%%%%% %%%%%%%% % Code for typesetting footnotes from tcolorboxes outside of the box, and in the main footnote sequence \newif\iffootaux \newcounter{footaux}% for \csname \newcounter{auxpage}% to handle frontmatter etc. \setcounter{auxpage}{1} \makeatletter \def\footnoteaux{\@ifnextchar[\@xfootnoteaux{\stepcounter{footnote}% \footnotemark[\thefootnote]\@footaux[\thefootnote]}} \def\@xfootnoteaux[#1]{\footnotemark[#1]\@footaux[#1]} \def\footaux{\@ifnextchar[\@footaux{\@footaux[\thefootnote]}} \def\@footaux[#1]#2{\protected@write{\@auxout}{\let\theauxpage\relax}{\string\newfootnote{\theauxpage}{#1}{#2}}} \newcommand{\newfootnote}[3]{% #1 = \theauxpage, #2 = \thefoontnote, #3 = text \ifnum#1=1\relax \footnotetext[#2]{#3}% \else \stepcounter{footaux}% \expandafter\xdef\csname footauxpage\thefootaux\endcsname{#1}% \expandafter\xdef\csname footauxnumber\thefootaux\endcsname{#2}% \expandafter\protected@xdef\csname footauxtext\thefootaux\endcsname{#3}% \fi} % to run at the end of every page (debug version) \newcommand{\addfootaux}{\loop \@ifundefined{footauxpage\thefootaux}{\footauxfalse}{% \count1=\csname footauxpage\thefootaux\endcsname\relax \advance\count1 by -1 \ifnum\count1=\value{auxpage}% \expandafter\let\expandafter\footauxnumber\csname footauxnumber\thefootaux\endcsname \expandafter\let\expandafter\footauxtext\csname footauxtext\thefootaux\endcsname \footnotetext[\footauxnumber]{\footauxtext}% \footauxtrue \else \footauxfalse \fi} \iffootaux \global\expandafter\let\csname footauxpage\thefootaux\endcsname\relax \global\expandafter\let\csname footauxnumber\thefootaux\endcsname\relax \global\expandafter\let\csname footauxtext\thefootaux\endcsname\relax \stepcounter{footaux}% \repeat \stepcounter{auxpage}} \makeatother \AtBeginDocument{\setcounter{footaux}{1}}% reset counter after \newfootnote \AddToHook{shipout/after}{\addfootaux} %%%%%%%% %%%%%%%% \newtcbtheorem[number within=section, number freestyle={\noexpand\thesection.\noexpand\arabic{\tcbcounter}}]{example}{Example}{ detach title, before upper={\tcbtitle.\quad \let\footnotetext=\footaux \let\footnote=\footnoteaux }, enhanced jigsaw, sharp corners, frame hidden, lines before break=4, borderline west={.5pt}{3pt}{black}, right=0pt, toprule=0pt, rightrule=0pt, bottomrule=0pt, leftrule=.5pt, colback=white, colframe=black, breakable=true, opacityback=0, colbacktitle=white, opacitybacktitle=0, coltitle=black, titlerule=0pt, fonttitle=\bfseries, parbox=false, label type=example, }{exp} % Demonstration text \usepackage{lipsum} % Credit to musarithmia for Sator square % https://tex.stackexchange.com/a/208857 % Retrieved 2026-01-17, License - CC BY-SA 3.0 \newcommand{\satorsquare}{ {\huge\bfseries%\hfil% \begin{tabular}{|c|c|c|c|c|} \hline S & A & T & O & R\\ \hline A & R & E & P & O\\ \hline T & E & N & E & T\\ \hline O & P & E & R & A\\ \hline R & O & T & A & S\\ \hline \end{tabular}}} \begin{document} \title{Afterpage hammering to cause crash} \maketitle \tableofcontents % Generate enough text that the table of contents moves things across pages \foreach \n in {1,...,35} { \section{C} \lipsum[\n]%\footnote{This is a footnote from outside an example} } % Generate progressively longer examples with afterpaged figures \foreach \n in {1,...,3} { \typeout{On Example \n} % Put a float into an afterpage \afterpage{ \begin{figure} {\centering \satorsquare{} \caption{figure}{This is a Sator square} \label{fig:onesatorsquare\n} } \end{figure} } % Force a clearpage \clearpage % Typeset text in a breakable tcolorbox \begin{example}{Example}{exp\n} \lipsum[1-3] \lipsum[\n-\n+\n] \end{example} } % Generate progressively longer examples with afterpaged figures and footnotes handled with shipout \foreach \n in {1,...,3} { \typeout{On Example 3+\n} % Put a float into an afterpage \afterpage{ \begin{figure} {\centering \satorsquare{} \caption{figure}{This is a Sator square} \label{fig:onesatorsquare\n} } \end{figure}} % Force a clearpage \clearpage % Typeset text in a breakable tcolorbox with a footnote that is placed outside the box \begin{example}{Example}{exp\n} \lipsum[1-3]\footnote{This is a footnote from inside an example} \lipsum[\n-\n+\n] \end{example} } \end{document}

My problem Some of the lines in the PDF of my LaTeX document are different thicknesses. This applies to lines generated using the commands frac, \overline and underline (I'm not sure about the latter). Sometimes the thickness is correct, and sometimes it is much too thick. The thickness varies throughout the document and depending on the zoom level. My main issue is that it persists after printing the document. This problem don't affect lines generated by \rule or \hline. Here is an example: Some details I use LuaLaTeX. I use TexLive on Linux.

I tried to fix this issue with ChatGPT but unfortunately I couldn't get it to work properly. I am trying to build a document in which I can input the number of exercises in an exam which then adjusts the header of a table. For example: If I input a number of 7 exercises, I want the header to have 7 columns in which I can later enter the achieved score of the students. Unfortunately I always get the error "Missing \endgroup inserted." and I somehow figured it has to do something with the combined use of \multidoand \tabularx.

I am trying to reproduce some images from old lecture notes, in particular notes by Prof. Gorni dating back to the 1993/94 academic year (pag. 4), or in other notes, like this picture At that time I had no knowledge of LaTeX at all. I do not know whether those figures were produced using PSTricks or with XFig/WinFig via psfrag, but my goal is to reproduce them in TikZ, correctly coloring the relevant half-planes. I am not completely sure whether it is possible (or appropriate) to modify the domain by introducing a square with a gray background or a path, but I have nevertheless quickly put together a minimal working example. \documentclass[a4paper,12pt]{article} \usepackage{amsmath} \usepackage{tikz} \usetikzlibrary{arrows.meta,decorations.markings,backgrounds} \usepackage{geometry} \geometry{margin=2.5cm} \begin{document} \begin{center} \begin{tikzpicture}[scale=1.5] \draw[->] (-0.2,0) -- (2,0) node[right] {$x$}; \draw[->] (0,-0.2) -- (0,2) node[above] {$y$}; \def\a{1.75} \begin{scope}[on background layer] \fill[gray!25] (-\a,\a) -- (\a,\a) -- (\a,-\a) -- (-\a,\a) -- cycle; \end{scope} \draw[thick,white] (-\a,-\a) rectangle (\a,\a); \draw[thick] (-1.5,1.5) -- (1.5,-1.5); \node at (-1.25,0.55) {$y=-x$}; \draw[thick] ({sqrt(2)},0) arc (0:90:{sqrt(2)}); \fill (0,{sqrt(2)}) circle (0.6pt); \fill ({sqrt(2)},0) circle (0.6pt); \node[left] at (0,{sqrt(2)}) {$\left(0,\sqrt{2}\right)$}; \node[below] at ({sqrt(2)},0) {$\left(\sqrt{2},0\right)$}; \end{tikzpicture} \end{center} \end{document} The problems I am facing (also because I have never attempted anything like this before) are the red rectangles (I wonder if there is a simple option to place the arc vector in a central position):

Good afternoon, I am trying to type my first book in ConTeXt. My intent is to produce a bibliographic section at the end of each chapter. Regarding the citations, I would like that: First, they appear as superscripts. Second, each citation for each chapter has appended a letter of the alphabet—say "A" for chapter one, "B" for chapter two etc. In addition, I would like that the superscript citation appears also as an entry into the bibliography—like this: The bibliography file where I setup the appearance has this code: \unprotect \loadbtxdefinitionfile[aps] \setupbtx[aps:list][ authorconversion=invertedshort, stopper:initials={.\btxspace}, separator:names:2={\removeunwantedspaces\btxsemicolon}, separator:names:3={\removeunwantedspaces\btxsemicolon}, separator:names:4={\removeunwantedspaces\btxsemicolon}, ] \setupbtx[aps:list:numbering][ left={(}, right={)}, ] \setupbtxlist[ distance=0pt, width=2.5em, align=flushleft, ] \setupbtx[aps:list:volume][style=italic] \setupbtx[aps:list:title:electronic][style=,] \starttexdefinition mutable protected btx:aps:author \btxdoif {author} { \btxflush{author} } \stoptexdefinition \starttexdefinition mutable protected btx:aps:title \btxdoifelse {title} { \texdefinition{btx:aps:composed-title}{title} \btxperiod } { \removepunctuation } \stoptexdefinition \starttexdefinition mutable protected btx:aps:journal-volume-year \btxdoif {journal} { \btxspace \btxstartstyleandcolor[aps:list:journal] \btxflush{expandedjournal -> journal} \btxstopstyleandcolor \btxdoif {year} { \btxspace \bold{\texdefinition{btx:aps:year}} \btxcomma } \btxdoif {volume} { \btxspace \btxstartstyleandcolor [aps:list:volume] \btxflush{volume} \btxstopstyleandcolor \btxcomma } \btxdoif {pages} { \btxspace \btxflush{pages} } } \stoptexdefinition \starttexdefinition mutable protected btx:aps:editionset \removeunwantedspaces \removepunctuation \btxdoif {edition} { \btxcomma \begingroup\pushoverloadmode \def\highordinalstr##1{##1} \ordinalnumber{\btxflush{edition}} \popoverloadmode\endgroup \btxspace \btxlabeltext{aps:edition} \btxsemicolon } \doif {\currentbtxcategory} {techreport} { \btxsemicolon \btxdoifelse {type} { \btxusecommand [\currentbtx:type] { \btxflush{type} } } { \btxlabeltext{technicalreport} } } \btxdoif {volume} { \btxcomma \btxoneorrange {volume} { \btxlabeltext{aps:Volume} } { \btxlabeltext{aps:Volumes} } \btxspace \btxflush{volume} \btxcomma } \btxdoif {number} { \removeunwantedspaces \removepunctuation \btxspace \btxflush{number} \btxcomma } \btxdoif {pages} { \btxoneorrange {pages} { \btxlabeltext{p} } { \btxlabeltext{pp} } \btxnbsp \btxflush{pages} \btxcomma } \stoptexdefinition \starttexdefinition mutable protected btx:aps:publisher-wherefrom-year \removeunwantedspaces \removepunctuation \btxsemicolon \btxdoifelse {institution} { \btxdoif {address} { \btxflush{address} \btxcolon } \btxflush{institution} \btxcomma } { \btxflush{publisher} \btxdoifelse {address} { \btxdoif {publisher} { \btxcolon } \btxflush{address} \btxcomma } { \btxdoif {publisher} { \btxcomma } } } \texdefinition{btx:aps:year} \stoptexdefinition \protect \usebtxdefinitions[aps] \usemodule[bibtex] \enabletrackers[publications, publications.crossref, publications.details, publications.cite, publications.strings] \definebtxrendering[bibrendering][aps][dataset=main] \usebtxdataset[default][Parts/Bibliography/Bibliografia.bib] \defineconversion[dynamicAlpha][\Characters{\getmarking[chapternumber]}-\numbers] \setupbtx[default:cite][ alternative=superscript, numberconversion=dynamicAlpha, ] \setupbtx[default:list][ numberconversion=dynamicAlpha, ] \setupbtxrendering[default][ specification=aps, dataset=default, criterium=chapter ] Thank you in advance for the attention and the help.

This \newcommand only works in the simplest cases and breaks as soon as multiple aliases are defined or new compounds are introduced later. \documentclass{article} \usepackage{chemnum} \newcommand\makecmpdalias[2]{% % ensure target exists (without printing) \cmpd*{#1}% % define alias label (without printing) \cmpd*{#2}% % copy printed representation from #1 to #2 \setcmpdlabel{#2}{\cmpdproperty{#1}{counter-representation}}% % undo the counter step caused by defining #2 \addtocounter{cmpdmain}{-1}% } \begin{document} \makecmpdalias{A}{B} \makecmpdalias{D}{E} \makecmpdalias{F}{H} \cmpd{A} \cmpd{B} \cmpd{A,B} \cmpd{C} \cmpd{D} \cmpd{E} \cmpd{F} \cmpd{G} \cmpd{H} \cmpd{I} \end{document} I am using chemnum and referencing compounds via \cmpd{...}. What I want is a simple alias mechanism: \cmpd{A} should define/print compound 1 after \makecmpdalias{A}{B}, \cmpd{B} should also print 1 (B is an alias for A) importantly, the next new compound should continue numbering normally, so \cmpd{C} should print 2 (not 3) similarly D and E should share one number. Expected output: 1 1 1 and 1 2 3 3 4 5 4 6 Actual output with my attempt: So the numbering becomes out of order (C becomes 3, then D/E become 2)....

I would like to make a set of frames that behave like overprint, but where the frame number increases automatically and where beamerpauses is set such that \beamerdefaultoverlayspecification{<alert@+|+->} formats things automatically. Below I give an example that compiles and does show the output that I want for this particular document, but I've hacked things (i.e., experimented and copy/pasted things that I don't even understand) so much I'm hoping there is a better way. That is, I fear I am abusing the overprint environment and I should be doing things fundamentally a different way. Is there a more "natural" Beamer way to do this, but still with automating the things I want (i.e., avoiding hardcoding of overlay numbers as much as possible and keeping the body of the document as simple as possible even if a long preamble is needed)? Also, I do not want to copy/paste/repeat any content. I would prefer hackish, if necessary, over duplicate content across frames. \documentclass{beamer} \setbeamertemplate{footline}[frame number]{} \beamerdefaultoverlayspecification{<alert@+|+->} % THE REST OF THIS PREAMBLE INJECTS INCREMENTING THE FRAME NUMBER FOR EACH % \onslide AND IT ALSO SETS THE "BEAMERPAUSES" COUNTER APPROPRIATELY. \makeatletter \newcount\my@onslide@first % Compute the first (minimum) overlay number that Beamer decodes from <#1>, % respecting + and . forms, without consuming a pause. \def\my@onslide@getfirst#1{% \begingroup % save state that the decoder mutates globally \count@\beamer@minimum \@tempcnta=\value{beamerpauses}% % prevent the probe decode from advancing beamerpauses \let\my@orig@stepcounter\stepcounter \def\stepcounter##1{% \edef\my@tmp{##1}% \edef\my@bp{beamerpauses}% \ifx\my@tmp\my@bp % no-op \else \my@orig@stepcounter{##1}% \fi }% % run Beamer's overlay-spec decoder \beamer@masterdecode{#1}% % capture the decoded minimum overlay \global\my@onslide@first=\beamer@minimum\relax % restore mutated globals \global\beamer@minimum=\count@\relax \global\setcounter{beamerpauses}{\the\@tempcnta}% \endgroup } % Wrap \onslide (star + nonstar), only when a <...> spec is present \let\my@orig@onslide\onslide \def\onslide{% \@ifstar{\my@onslide@wrapstar}{\my@onslide@wrapnostar}% } \def\my@onslide@wrapnostar{% \@ifnextchar<{\my@onslide@withspec}{\my@orig@onslide}% } \def\my@onslide@wrapstar{% \@ifnextchar<{\my@onslide@withspecstar}{\my@orig@onslide*}% } \def\my@onslide@withspec<#1>{% \my@onslide@getfirst{#1}% % automate the trick here: % https://tex.stackexchange.com/questions/329956/beamer-keep-text-position-in-consecutive-frames-or-how-to-get-overprint-to-inc \only<\the\my@onslide@first>{\stepcounter{framenumber}}% % make it so that the default overlay increment works. \setcounter{beamerpauses}{\the\my@onslide@first}% \my@orig@onslide<#1>% } \def\my@onslide@withspecstar<#1>{% \my@onslide@getfirst{#1}% \only<\the\my@onslide@first>{\stepcounter{framenumber}}% \setcounter{beamerpauses}{\the\my@onslide@first}% \my@orig@onslide*<#1>% } \makeatother \begin{document} \begin{frame} Definitition: Let $X$ be a rv.

How to return an array from a command? or rather How to expand a command to some generated array? The code below generates the correct array into \OutArray inside \Transmogrifier, but I don't know how to return it to calling \ResultArray. I know one option to access the values is to define an empty array, give the array as an argument to the command, have the command generate the elements to that array and access them when the command is finished. This is not what I am looking for. My question is more to expand my understanding and increase the tools I have in my disposal. \documentclass[tikz]{standalone} \begin{document} \newcommand*{\SomeOperation}[2]{% \fpeval{#1*#2}% }% \newcommand*{\Transmogrifier}[2]{% \pgfmathparse{dim(#1)}% or \pgfmathdim{#1}% \edef\ArrayLength{\pgfmathresult}% \xdef\OutArray{{}}% \foreach \i in {0,...,\fpeval{\ArrayLength-1}}% {% \pgfmathparse{array({#1},\i)}% or \pgfmatharray{{#1}}{\i}% \ifnum \i=0% \xdef\OutArray{\SomeOperation{\pgfmathresult}{#2}}% \else% \xdef\OutArray{\OutArray,\SomeOperation{\pgfmathresult}{#2}}% \fi% }% \xdef\OutArray{{\OutArray}}% How to "return" \OutArray? %\typeout{OutArray: \OutArray}% }% \begin{tikzpicture} \def\TestArray{{1,2,3}}% \typeout{TestArray: \TestArray}% \newcommand*{\ResultArray}{% \Transmogrifier{\TestArray}{2}% }% %\ResultArray% Temp for testing \typeout{ResultArray: \ResultArray}% \end{tikzpicture} \end{document} Desired outcome in the log file: TestArray: {1,2,3} ResultArray: {2,4,6}

I used to have Alegreya font installed (presumably from google since it inception). As I migrated to a new system MikTeX said the Alegreya font I installed is not a TTC.

The xmp description can be set for example using hyperref: \DocumentMetadata{ lang=en-US } \documentclass{article} \usepackage{hyperref} \hypersetup{ pdfsubject={This will end up as the english subject.} } \begin{document} test \end{document} exiftool then reveals: Description : This will end up as the english subject. Description (en-US) : This will end up as the english subject. Language : en-US coming from the XMP block [...] <dc:description> <rdf:Alt> <rdf:li xml:lang="x-default">This will end up as the english subject.</rdf:li> <rdf:li xml:lang="en-US">This will end up as the english subject.</rdf:li> </rdf:Alt> </dc:description> [...] which seems to suggest that the Description may also be set for other languages. How can I for example set the description for something like de-DE?

In my example I want to calculate integers / getting the sum of entries based on various filtering options. Instead of using datatools macros, I’d like to get it done with LaTeX3/expl3-commands. The problem is the part: \int_set:Nn \l_tmpb_int { \dfgCountPosition[#1]{#2}{f} } which tells me in the log: ! Missing number, treated as zero. <to be read again> \xparse function is not expandable l.94 .../d): \dfgTotalPosition{PostDoc} but as far as I can see there is no \int_set:Nx for using an expansion therefor this is not the solution.

Layout of figures and tables will be adjusted by the publisher during the production process, so authors should not concern themselves with placement to avoid disappointment and wasted effort. Simply place the LATEX code close to where the figure or table is first mentioned in the text and leave exact placement to the publishers.

I’m trying to define a LaTeX command that creates a figure containing multiple subfigures from a comma-separated list of image names. I’d like a macro with this interface: \multipleIMG{<images per row>}{<comma-separated list of image files>}{<main label>}{<main caption>} Requirements: Use the full available width (\linewidth). No horizontal and vertical gaps between images. Each row should be centered as a whole (even the last row if it’s not full). All images must have the same width (based on <images per row>). Create sublabels automatically as <main label>_1, <main label>_2, … (1, 2, 3, …). I’m using subcaption. I don’t want visible subcaptions, only labels for referencing (\phantomcaption is fine). Example input: \multipleIMG{3}{location-1,location-2,location-3,location-4,location-5}{fig:first}{Five Figure} This should produce 3 images in the first row, then 2 centered images in the second row, all with equal widths, and labels: fig:first_1, fig:first_2, fig:first_3, fig:first_4, fig:first_5 So that I can reference both the main figure and a subfigure like: \ref{fig:first}, \ref{fig:first_1} Here is an MWE showing the layout I want (hard-coded manually for 5 images). I want to replace this manual code with \multipleIMG. \documentclass{report} \usepackage[demo]{graphicx} \usepackage{subcaption} \usepackage[colorlinks=true]{hyperref} \begin{document} \begin{figure}[htbp] \centering \newlength{\imgw} \setlength{\imgw}{\dimexpr\linewidth/3\relax} \makebox[\linewidth][c]{% \begin{subfigure}{\imgw} \includegraphics[width=\linewidth]{} \phantomcaption \label{fig:first_1} \end{subfigure}% \begin{subfigure}{\imgw} \includegraphics[width=\linewidth]{} \phantomcaption \label{fig:first_2} \end{subfigure}% \begin{subfigure}{\imgw} \includegraphics[width=\linewidth]{} \phantomcaption \label{fig:first_3} \end{subfigure}% } \vspace{-\baselineskip} \makebox[\linewidth][c]{% \begin{subfigure}{\imgw} \includegraphics[width=\linewidth]{} \phantomcaption \label{fig:first_4} \end{subfigure}% \begin{subfigure}{\imgw} \includegraphics[width=\linewidth]{} \phantomcaption \label{fig:first_5} \end{subfigure}% } \caption{Five Figure} \label{fig:first} \end{figure} \ref{fig:first}, \ref{fig:first_1} \end{document}

This question is a matter of curiosity, rather than a problem. Just yesterday, my texlive-bin was updated. Current version says that luatex (actually luahbtex is version 1.21.0. I do not get the binaries from TeXlive: Mya Android system, with Linux-like Termux app, gets a custom-build via Termux, because the file paths (and some other things) are different. Typically, I get the texlive-bin programs a few weeks later than they are released to others. Otherwise, the non-binaries come from TeXlive. As texlive-bin was being instllaed, the Terminal told me that it would be using Lua 5.2 for support; it was already in my system. But my own documents rely on Lua features that were unavailable until Lua 5.3. Nevertheless, all good. Behold: \documentclass{article} \directlua{ if (_VERSION >= 'Lua 5.3') then texio.write('LUA GOOD') else texio.write('LUA BAD') end } \begin{document} Hello, World. \end{document} It tells me LUA GOOD, even though Lua is version 5.2. I deduce that the Lua built into luahbtex is 5.3 or later. Others have asked whether the Lua is internal or external, and it has been answered: internal. But if I try to remove Lua (any version) from my system, it cannot be removed unless I also remove texlive-bin. Evidently, the installer believes that system Lua support is needed, even though the system version and built-in version do not match. Is there a reason for that? Or is it just how the installer script was written?

This very simple code doesn't work, but I don't know what needs fixing. \documentclass{article} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usetikzlibrary{patterns} \begin{document} \begin{tikzpicture} \begin{axis}[ [ xmin=0, xmax=100, y tick label style={/pgf/number format/1000 sep=}, symbolic y coords={Lecture, Jeux vidéo, Sport, Smartphone}, ytick=data ] \addplot[ xbar, fill=lightgray, ] coordinates { (10, Lecture) (50, Jeux vidéo) (30, Sport) (90, Smartphone) }; \end{axis} \end{tikzpicture} \end{document}

Context All I want is to be able to plot nice 3D plots of functions of 2 variables. In another question of mine, it became clear to me that pgfplots is limiting my ability to do so. It was suggested to me to try out Asymptote. No problem, I am willing to learn... but I can't get it to compile on my setup. I've spent more time than I'm willing to admit on this and I need help. My Setup I am on Windows 11, I use TexStudio 4.9.1 and Tex Live (fresh install) and this is my Asymptote version and location C:\Users\USER>asy --version Asymptote version 3.04 [(C) 2004 Andy Hammerlindl, John C. Bowman, Tom Prince] ENABLED OPTIONS: V3D 3D vector graphics output WebGL 3D HTML rendering OpenGL 3D OpenGL rendering SSBO GLSL shader storage buffer objects GSL GNU Scientific Library (special functions) FFTW3 Fast Fourier transforms Eigen Eigenvalue library XDR External Data Representation (portable binary file format for V3D) CURL URL support LSP Language Server Protocol Readline Interactive history and editing GC Boehm garbage collector threads Render OpenGL in separate thread DISABLED OPTIONS: Sigsegv Distinguish stack overflows from segmentation faults C:\Users\ORION>where asy C:\texlive\2025\bin\windows\asy.exe I use this line for compilation: pdflatex.exe --shell-escape -synctex=1 -interaction=nonstopmode %.tex I am aware that I should be compiling 3 times (the file is called test.tex): pdflatex test.tex asy test-1.asy pdflatex test However the first pdflatex compilation fails. The problem I am trying to run the simple code: \documentclass[12pt]{article} \usepackage{asymptote} \begin{document} This is a test \begin{asy} size(5cm); draw((0,0)--(1,1)); \end{asy} \end{document} and here is a snippet of the error log (at the end): (c:/texlive/2025/texmf-dist/tex/latex/latexconfig/epstopdf-sys.cfg File: epstopdf-sys.cfg 2010/07/13 v1.3 Configuration of (r)epstopdf for TeX Live )) \openout3 = `test-1.asy'. ) Runaway argument? ! File ended while scanning use of \next. The file I am trying to compile is called test.tex and it produces a test-1.asy file which contains the following code: \end{asy} ^ C:\Users\***\test\test-1.asy: 13.2: invalid token '\' \end{document} ^ C:\Users\***\test\test-1.asy: 14.1: invalid token '\' \end{document} ^ C:\Users\***\test\test-1.asy: 14.2: syntax error: error: could not load module 'C:\Users\***\test\test-1.asy' I find it weird that it starts with \end{asy} and I suspect this is what causes the "runaway argument" error when compiling. What I have tried Deleting all but the .tex file in the working folder and recompile. I asked Crixet about this and it told me to play around the [inline] option with \usepackage{asymptote}. It changed nothing. It asked me to look into the test.pre file, which only contains: \InputIfFileExists {\jobname -1.pre}{}{} It says there should be no space between \jobname and -1.pre and that this causes asymptote not to find the test-1.asy file. I'm not 100% about this and even if it is true, why there is a space there is beyond me. I tried running the code using a command prompt with pdflatex test.tex within the folder but get the same error, so this does not seem to be caused by TexStudio. At first I was using MikTex. I had the same issue and heard that "MikTex had an outdated Asymptote package" and "I should switch to TexLive" which I did (after having uninstalled MikTex). So it seems like the issue isn't with MikTex or Tex Live either. I have the same setup (TexStudio + MikTex) on a laptop with Kubuntu and the same code works fine. I could use this but it is not optimal for my workflow. It seems to me like other people are able to run this fine on Windows, so I don't see why I couldn't. What I'm looking for I am at a loss as to what causes this issue. Also, I'm okay with understanding Latex "code" but anything outside like running command line, changing TexStudio configuration, etc. is not something I'm experienced with. So please, if you reply, explain like I'm five, because saying things that might seem obvious like "Make sure asymptote is on path" is really not clear to me. Thanks in advanced for all the help.

I am working with the "exam" class by Philip Hirschhorn (version 2.704) and I am experiencing some trouble with the spacing of lists, itemize in my case, in solution environments. I see strong differences between the spacing in the "solutionbox" and the other solution environment but I am not proficient enough in lower level Latex or Tex to figure out the reason and potential solutions myself. I could make the lists behave the same by using "enumitem" with \setlist[itemize, 1]{nosep}. As far as I understand, this means that the list settings are actually changing between the different environments. I am interested in an explanation of the underlying mechanisms. Here is a minimum working example for you \documentclass[11pt, answers]{exam} \renewcommand{\solutiontitle}{% \textbf{Solution:}% \par% \noindent% } \begin{document} \textbf{Start of Document} \begin{questions} \question This is a solutionbox environment \begin{solutionbox}{5cm} The solution is either \begin{itemize} \item A \textbf{or} \item B \end{itemize} But it could also be C in a new paragraph. Or D in another new paragraph. \end{solutionbox} \question This is a solution environment \begin{solution} The solution is either \begin{itemize} \item Z \textbf{or} \item Y \end{itemize} But it could also be X in a new paragraph. Or W in another new paragraph. \end{solution} \end{questions} \textbf{End of Document} \end{document} You can see the difference in this screenshot montage it looks like the line spacing is identical but some lengths in the list environment are modified, such as \itemsep or \parsep The behavior of the solution environment is identical with the other solution environments (solutionorbox, etc.) as far as I see. The documentation says that the solutionbox environment is implemented differently from the other environments. I guess that this is part of the reason. Thanks in advance, Simon

I’m trying to define a custom language in LaTeX using \lstdefinelanguage so that keywords and variables in MusicBrainz Picard scripts are highlighted similarly to Picard’s built-in script editor (see MusicBrainz Picard Script Reference below). Here’s what I have so far: My Code \documentclass{article} \usepackage{listings} \usepackage{xcolor} \lstdefinelanguage{PicardScript}{ sensitive=true, morecomment=[l]{\#}, morestring=[b]", morekeywords=[1]{% $if,$if2,$left,$right,$num,$replace, $gt,$lt,$eq,$ne,$and,$or,$not,$len, $lower,$upper }, morekeywords=[2]{% \%artist\%,\%albumartist\%,\%album\%,\%title\%, \%date\%,\%originaldate\%,\%tracknumber\%, \%discnumber\%,\%totaldiscs\% }, keywordstyle=[1]\color{blue}\bfseries, keywordstyle=[2]\color{orange}, stringstyle=\color{red}, identifierstyle=\color{black}, commentstyle=\color{gray}\itshape } \lstset{ basicstyle=\ttfamily\tiny, numbers=left, numberstyle=\tiny\color{gray}, stepnumber=1, numbersep=5pt, showstringspaces=false, breaklines=true, tabsize=4, frame=single, commentstyle=\color{gray}\itshape } \begin{document} \begin{lstlisting}[language=PicardScript] $if2(%albumartist%,%artist%)/ ($left($if2(%originaldate%,%date%),4)) $replace(%album%,:,)/ $if($gt(%totaldiscs%,1),$num(%discnumber%,2)-)$num(%tracknumber%,2) - %artist% - %title% \end{lstlisting} \end{document} My Output: I would like the LaTeX output to match the coloring style of the Picard script editor. How can I modify my \lstdefinelanguage definition to better replicate the Picard script editor’s keyword coloring? MusicBrainz Picard Script Reference: Link: https://picard.musicbrainz.org/

The following MWE produces a nice square root sign provided by MTPro-II \documentclass{report} \usepackage{amsmath} \usepackage{mtpro2} \begin{document} \[ \SQRT{\begin{pmatrix} 1 & 0 & 0 \\ 0 & 4 & 0 \\ 0 & 0 & 9 \end{pmatrix}} \] \end{document} This works fine under pdflatex and xelatex producing the nice slanted surd portion of the square root sign But when processed with lualatex it goes back to the old CM square root sign Can anyone shed light on what is going on?

I have the following code: \documentclass[tikz,border=5pt]{standalone} \begin{document} \ExplSyntaxOn \keys_define:nn {mykey} { foo .tl_set:N = \l_tmpa_tl } \keys_set:nn {mykey} { foo = {O\quad K},%<- } \begin{tikzpicture} \draw[dotted] (0,0) -- (2,0); \node[inner~sep=0pt] at (1,0) {\l_tmpa_tl}; \end{tikzpicture} \begin{tikzpicture} \draw[dotted] (0,0) -- (2,0); \node[fill=white,inner~sep=0pt] at (1,0) {\l_tmpa_tl}; \end{tikzpicture} \ExplSyntaxOff \begin{tikzpicture} \draw[dotted] (0,0) -- (2,0); \node[fill=white,inner sep=0pt] at (.7,0) {O}; \node[fill=white,inner sep=0pt] at (1.3,0) {K}; \end{tikzpicture} \end{document} For the sake of the template settings, the text O\quad K should be put as a token list, as a whole, but I need the third picture's result. Is that possible to just fill=white to just shade the "text area"? Edited: Since cfr commented for the original template case, I would provide more information. Claims: The original package is exam-zh package It depends on xeCJK, so xelatex is must I was not sure that whether it's CJK fonts settings works on every OS. See here. What I want, is to achieve something sealline style as below: It appeared in the leftmargin of exam paper: Now I have the following code: \documentclass{exam-zh} \usepackage{zhlipsum} % \ExplSyntaxOn % % Line 1487 in exam-zh.cls % % https://github.com/xkwxdyy/exam-zh/blob/main/exam-zh.cls#L1487-L1496 % \cs_set:Npn \__examzh_sealline_odd_text_around_line: % { % \node [ anchor = east ] % at ([xshift = -\g__examzh_sealline_odd_text_xshift_dim, yshift = \g__examzh_sealline_odd_text_yshift_dim]current~page~text~area.west) % { % \g__examzh_sealline_odd_text_format_tl % \__examzh_sealline_odd_spread_box:nn { \g__examzh_sealline_odd_text_width_dim } % { \g__examzh_sealline_odd_text_tl } % }; % } % \ExplSyntaxOff \examsetup{ sealline={ show=true, circle-show=false, line-type={loosely-dotted}, text={密封线},%<- the text here is put as `\g__examzh_sealline_odd_text_tl' text-format={\huge\bfseries}, line-thickness={2.5pt}, text-xshift={.375cm} } } \begin{document} \zhlipsum[name=zhufu] \end{document} That is the original case. Noted that 密封线, the l3keys sealline/text is put into \g__examzh_sealline_odd_text_tl ands \g__examzh_sealline_even_text_tl here(why I say as a whole). Which need to be processed by \__examzh_sealline_odd_spread_box:nn here. I want to change the present settings of exam-zh's setting code to the minimal extent.(Of course, I can type text={}, leave it empty, and follow \__examzh_sealline_odd_circle: here to draw multiple \node[fill=white] {密}s) But that change too much the package's setting. So, I simplified it to my origianl post😊.

I want to create a command \isthisprime{<number>} where it decides whether <number> is or is not prime, and if it is, it also returns the order of the prime (eg, 2 is the first, 3 is the second, and so on). Here is my attempt at a code (excuse my choice of naming the counters): \documentclass{article} \usepackage{amsmath} \usepackage{enumitem} \usepackage{lipsum,blindtext} \newcount\div \newcount\divs \newcount\somnum \newcount\yes \newcount\yess \newcount\numberofprimes \newcommand{\isthisprime}[1]{% %Decide if #1 is prime \div=2 \yes=0 \ifnum#1<2 \yes=1 \fi \loop \ifnum\div<#1 \ifnum#1=\numexpr(#1/\div)*\div\relax \yes=1 \fi \advance\div by 1 \repeat \numberofprimes=0 \somnum=2 \yess=0 \divs=2 %Checking every number less than or equal to #1 \ifnum\yes=0 \loop \ifnum\somnum<\numexpr#1+1\relax \loop%checking if somnum is prime \ifnum\divs<\somnum \ifnum\somnum=\numexpr(\somnum/\divs)*\divs\relax \yess=1 \fi \advance\divs by 1 \repeat \ifnum\yess=0 \advance\numberofprimes by 1 \fi \yess=0\divs=2\advance\somnum by 1 \repeat \fi \ifnum\yes=0 #1 is a prime with index~\the\numberofprimes. \else #1 is not a prime. \fi } \begin{document} \isthisprime{101}\newline \isthisprime{102} \end{document} The idea: the first part of the code decides whether or not <number> is a prime; if it is we set the counter \yes=1, otherwise it remains equal to 0. So if \yes=1 we check every number less than or equal to <number> to see if it is prime or not. At every occurrence of prime, we increase the counter \numberof primes. Hence \numberofprimes will determine the order of <number>, if it prime that is. The part where it decides whether or not the input is prime or not is fine. However, it cannot find its order. It just says that the order is 1 if the input is prime. It cannot see what is wrong with my code, so I would appreciate any advice! Thank you in advance.

I have a (far from ideal) collection of macros that I \include in the preambles of my documents. It's very useful in giving my documents uniform semantic representation. For example, contravariant vector component functions all have a common appearance which I control globally. The down-side to this is that when I want to post an except to math.stackexchange.com, for example, I have to manually convert all of my LaTeX code into standard LaTeX which is independent of my preamble. Obviously the Tex-engine (e.g., lualatex) converts my macros into a form that TeX understands which is equivalent to standard LaTeX. Is there a tool that will take my customized LaTeX documents and convert them into standard LaTeX? Here's an example. (Please don't question the sanity of my notation. I have professionals for that.) \documentclass[a4paper,10pt]{article} \usepackage{amsmath} \newcommand{\CONST}[1]{\mathrm{#1}} \newcommand{\dd}{\CONST{d}} % differential d \newcommand{\DD}[2]{\frac{\dd#1}{\dd\CONST{#2}}} % derivative \newcommand{\PD}[2]{\frac{\partial #1}{\partial\CONST{#2}}} % partial derivative \begin{document} Written using my macros: \begin{align*} \dd f & = \PD{f}{x}\dd x + \PD{f}{y}\dd y.\\ \DD{f}{t} & = \PD{f}{x}\DD{x}{t}+\PD{f}{y}\DD{y}{t} \end{align*} What I want the tool to output: \begin{align*} \mathrm{d} f & = \frac{\partial f}{\partial \mathrm{x}} \mathrm{d} x + \frac{\partial f}{\partial \mathrm{y}} \mathrm{d} y.\\ \frac{\mathrm{d} f}{\mathrm{d}\mathrm{t}} & = \frac{\partial f}{\partial \mathrm{x}}\frac{\mathrm{d}x}{\mathrm{d}\mathrm{t}} +\frac{\partial f}{\partial \mathrm{y}}\frac{\mathrm{d}y}{\mathrm{d}\mathrm{t}} \end{align*} \end{document}

I'm trying to draw these two diagram in a slide but I cannot do it. Anyone can help me please.
