I'm trying to customise listings captions using tikz, but the background of the code listing is drawn afterwards, covering the tikz caption. How can I ensure the caption to be drawn after/over the code? This is what I want to achieve: The Minimal Working Example (MWE) below shows where I got so far. In the orange examples (adding 4ex before and -5ex after) the tikz picture is properly aligned with the frame/background of the code; however, it's drawn below. Moreover, the vertical space between the previous text and the listing is the same in the cyan and red examples, but it's slightly increased in the orange examples, which I don't understand. On the other hand, the magenta examples use just -1ex before (no forced vertical spacing after) and are properly aligned with the frame/background of the code; but they require several \noparskip to avoid excessive vertical space from the previous text/title, which I neither understand. \documentclass[twoside,openright,11pt]{report} \usepackage[a4paper,margin=2cm]{geometry} \usepackage{filecontents} \edef\restoreparindent{\parindent=\the\parindent\relax} \RequirePackage{parskip} \restoreparindent \newcommand*{\noparskip}{\par\vspace{-\parskip}} \usepackage{fontawesome} \usepackage[dvipsnames,table]{xcolor} \usepackage{tikzpagenodes} % Loads tikz \usetikzlibrary{calc} \usepackage{caption} \usepackage{listings} \lstset{ language=C, basicstyle=\ttfamily, backgroundcolor=\color{gray!5}, frame=single, framerule=0pt, framesep=1ex, xleftmargin=1ex, xrightmargin=1ex, } \captionsetup[lstlisting]{ font={footnotesize,bf}, justification=raggedleft, singlelinecheck=false } \newcommand*\lstc[1]{\noparskip\lstinputlisting[firstline=5, caption = \faFileCodeO~\lstname]{#1}} \DeclareCaptionFormat{rulebox}{% \parbox{\linewidth}{% \makebox[\linewidth]{% \leaders\hrule height 0.5pt\hfill~#1#2#3% }% }% } \DeclareCaptionFormat{tikzrule}{% \begin{tikzpicture}[remember picture, overlay] \node[blue, anchor=east] (P) {#1#2#3}; \draw[blue] (current page text area.west|-0,0) -- (P); \end{tikzpicture} } \DeclareCaptionFormat{tikzrulebox}{% \begin{tikzpicture}[remember picture, overlay] \node[green, draw, anchor=north east] (P) {#1#2#3}; \draw[green] (current page text area.west|-0,0) -- (P.north west); \end{tikzpicture}% } \DeclareCaptionFormat{tikzruleboxpoff}{% \vspace*{4ex} \begin{tikzpicture}[remember picture, overlay] \node[cyan, draw, anchor=north east] (P) {#1#2#3}; \draw[cyan] (current page text area.west|-0,0) -- (P.north west); \end{tikzpicture}% } \DeclareCaptionFormat{tikzruleboxpoffn}{% \vspace*{4ex} \begin{tikzpicture}[remember picture, overlay] \node[red, draw, anchor=north east] (P) {#1#2#3}; \draw[red] (current page text area.west|-0,0) -- (P.north west); \end{tikzpicture}% \vspace*{-4ex} } \DeclareCaptionFormat{tikzruleboxpoffnd}{% \vspace*{4ex} \begin{tikzpicture}[remember picture, overlay] \node[orange, draw, anchor=north east] (P) {#1#2#3}; \draw[orange] (current page text area.west|-0,0) -- (P.north west); \end{tikzpicture}% \vspace*{-5ex} } \DeclareCaptionFormat{tikzruleboxnoff}{% \vspace{-1ex} \begin{tikzpicture}[remember picture, overlay] \node[magenta, draw, anchor=north east] (P) {#1#2#3}; \draw[magenta] (current page text area.west|-0,0) -- (P.north west); \end{tikzpicture}% } \begin{filecontents}{main.c} #include <stdio.h> #include <stdlib.h> int main () { printf("Hello!\n"); return 0; } \end{filecontents} \begin{document} \hrule \section*{Section title} \hrule \captionsetup[lstlisting]{format=rulebox} \lstc{main.c} \vspace*{5ex} \captionsetup[lstlisting]{format=tikzrule} \hrule TikZ Rule \hrule \lstc{main.c} \vspace*{5ex} \captionsetup[lstlisting]{format=tikzrulebox} \hrule TikZ Rule Box \hrule \lstc{main.c} \vspace*{5ex} \captionsetup[lstlisting]{format=tikzruleboxpoff} \hrule 4ex TikZ Rule Box \hrule \lstc{main.c} \vspace*{5ex} \captionsetup[lstlisting]{format=tikzruleboxpoffn} \hrule 4ex TikZ Rule Box -4ex (with rule) \hrule \lstc{main.c} \hrule 4ex TikZ Rule Box -4ex (no rule) \noparskip% \lstc{main.c} \newpage \captionsetup[lstlisting]{format=tikzruleboxpoffnd} \hrule 4ex TikZ Rule Box -5ex (with rule) \hrule \lstc{main.c} \hrule 4ex TikZ Rule Box -5ex (no rule) \noparskip% \lstc{main.c} \vspace*{5ex} \captionsetup[lstlisting]{format=tikzruleboxnoff} \hrule TikZ Rule Box N off (with hrule) \hrule \noparskip% \lstc{main.c} \hrule TikZ Rule Box N off (no hrule) \noparskip% \noparskip% \lstc{main.c} \end{document}

I have a .tex file that used to compile (here is the full file), but since an upgrade of my Debian system, which I assume pulled in some new version of LaTeX packages, it fails to build with this error when I run xelatex on it: ! LaTeX Error: Command \scr@tso@lstlisting@linefill undefined. That looks like some internal issue in koma-script/tocbasic.sty, but my understanding of LaTeX isn't enough to know what to do about it. That sty file looks like it checks for this command being undefined and then defines it, yet here I am with the error. I'd be grateful for a proper solution, of course, but also satisfied with a crude hack to suppress this error so that my pdf file builds again. Edit: This is a minimal reproduction. Seems that both listings and arabxetex have to be present to trigger the error. \documentclass{scrbook} \usepackage{listings} \usepackage{arabxetex} \begin{document} \end{document} Further edit: The suggested fix of adding a line like this... \makeatletter \def\scr@tso@lstlisting@linefill{} \def\scr@tso@lstlisting@pagenumberformat#1{} \makeatother ... avoids this issue, but somehow affects pdfpages in a way that breaks \includepdf.

I found this old question, which shows how to unconditionally capitalize words in section titles. However, title case normally does not capitalize every word, but, i.e., the Chicago Manual of Style recommends to not capitalize articles and conjunctions (among other exceptions). Is there maybe a package that achieves this? It's probably not to hard to code this with latex3, since in the end we have to capitalize every word which is not in some sort of ignore-list, but if someone has already done the work I would be happy to use it. Getting this to work well with toc entries and hyperref, might or might not be difficult.

I was just wondering what LaTeX package (if it's LaTeX at all) the following large straight parentheses and vertical integral symbols are from. These are my (very many) current latex packages and commands and stuff: \usepackage{graphicx} \usepackage{pgfplots} \graphicspath{{images/}} \usepackage{pgfplots} \usepackage{pdfpages} \usepackage[margin=2.5cm]{geometry} \usepackage{microtype} \usepackage{array} \usepackage{newtxtext} \usepackage{amssymb} \usepackage{amsmath} \pdfmapfile{=mtpro2.map} \usepackage[lite,subscriptcorrection,looser]{mtpro2} \usepackage{placeins} \usepackage{enumitem} \usepackage{delarray} \setlength{\parindent}{0pt} \newcommand{\qmarks}[1]{\hfill\mbox{\textbf{#1}}} \renewcommand{\thepage}{--\,\arabic{page}\,--} \usepackage{accents} \DeclareFontFamily{OMX}{cmex}{} \DeclareFontShape{OMX}{cmex}{m}{n}{<-> cmex10}{} \DeclareSymbolFont{thindelims}{OMX}{cmex}{m}{n} \DeclareMathDelimiter{(}{\mathopen} {operators}{"28}{thindelims}{"00} \DeclareMathDelimiter{)}{\mathclose}{operators}{"29}{thindelims}{"01} \renewcommand{\arraystretch}{1.2} \delimiterfactor=1000 \delimitershortfall=0pt \DeclareFontFamily{OML}{ntxmi}{} \DeclareFontShape{OML}{ntxmi}{m}{it}{<-> ntxmi}{} \DeclareSymbolFont{newtxletters}{OML}{ntxmi}{m}{it} \DeclareMathSymbol{z}{\mathalpha}{newtxletters}{`z} \DeclareMathSymbol{u}{\mathalpha}{newtxletters}{`u} \DeclareMathSymbol{v}{\mathalpha}{newtxletters}{`v} \DeclareSymbolFont{thinsymbols}{OMS}{cmsy}{m}{n} \DeclareMathRadical{\ssqrt}{thinsymbols}{"70}{thindelims}{"70} \DeclareSymbolFont{newtxpi}{OML}{ntxmi}{m}{it} \let\oldpi\relax \DeclareMathSymbol{\oldpi}{\mathord}{newtxpi}{"19} \renewcommand{\pi}{\ensurepath{\oldpi}} \DeclareMathSizes{12}{12}{9}{7}

I wrote my question in a comment within the following Asymptote code. My goal is to do a matrix multiplication (rotation, Rodriguez) on a sphere I made in Asymptote, without changing the camera. Rodriguez rotation is angle by axis, as opposed to Euler, which is by standard axes in a specific order. Also, any explanation as to why this is rather slow? I think it would be even clearer to pose this as a multiplication on an arbitrary triple. import three; unitsize(5cm); currentprojection=orthographic(1,2,3); /* draw((0,0) -- (1,1)); label("\(a\)", (0,1), (-1,-1)); draw((0,0)..controls (0,1) and (1,1)..(1,0)); */ triple SP(triple point){ return ( point.x / (1 - point.z), point.y / (1 - point.z), 0 ); } triple ISP(triple point){ real temp = point.x^2 + point.y^2; return ( 2 * point.x / (1 + temp), 2 * point.y / (1 + temp), (-1 + temp) / (1 + temp) ); } for(int i=-10; i<=10; ++i){ for(real j=-10; j<=10; j += 0.1){ if(j!=10){ draw(ISP((i,j,0)) -- ISP((i,j+1/10,0))); draw(ISP((j,i,0)) -- ISP((j+1/10,i,0))); /* My motivation in asking this question is to perform a general axis-angle (Rodriguez) transformation to this Riemann sphere, without changing the camera projection. I want to use a matrix multiplication, hopefully through a build in method with operator overloading and everything. */ } } }

This is a follow-up to the question posed here: How to Place a Tcolorbox Inline Next to a Title? Consider the following code which incorporates the suggestion of Ulrike Fischer: \documentclass[12pt]{book} \usepackage{scalefnt,color} \usepackage[many]{tcolorbox} \begin{document} \thispagestyle{empty} {\color{red} \scalefont{2.00}{\textbf{\textsl{TITLE1}}}}\\[20pt] \scalebox{1.87}{\textbf{\Huge{Title2}}} \tcbox[nobeforeafter,colback=yellow,width=0.75in,height=0.75cm]{Inline tcolorbox} %\tcbox[nobeforeafter,colback=yellow,width=1.75in,height=0.75cm]{Inline tcolorbox} \end{document} Which seems to produce the desired output: However, when I try to adjust width=0.75in to, say, width=1.75in, there appears to be no change in the width of the tcolorbox. Moreover, if I delete width=0.75in and run the code, the output appears to be very much the same as that displayed. QUESTION: Am I doing something wrong? The log file indicates "Process exited normally". How should I encode a change of width in the inline tcolorbox? Thank you.

In the following Minimal Working Example (MWE), I'd like to keep track of the totvalue of chapcnt within each part (since chapcnt is set to 0 at the beginning of each part). Currently, \totvalue{chapcnt} returns the number of chapters in the last part (the maximum after it is last reset in the document). \documentclass[twoside]{report} \let\latexthesection\thesection \renewcommand*{\thesection}{\arabic{section}} \usepackage{titlesec} \titleclass{\part}{top} \titleformat{\part}{\Huge\bfseries\color{blue}}{\thepart}{10pt}{} \titleclass{\chapter}{top} \titleformat{\chapter}{\Huge\bfseries\color{green}}{\thechapter}{10pt}{} \usepackage{tikz} \usetikzlibrary{calc} \usepackage{totcount, eso-pic, xifthen} \regtotcounter{partcnt} \newcounter{partcnt} \regtotcounter{chapcnt} \newcounter{chapcnt} \AddToShipoutPictureBG{% \begin{tikzpicture}[overlay] \ifthenelse{\isodd{\value{page}}}% {\def\corner{east}\def\sign{-}}% {\def\corner{west}\def\sign{+}} \pgfmathsetlengthmacro{\parttabheight}{\paperheight/\totvalue{partcnt}} \pgfmathsetlengthmacro{\parttaboffset}{(\thepartcnt-1)*\parttabheight} \fill[blue] ($(current page.north \corner)+(0,-\parttaboffset)$) rectangle ++(\sign.40,-\parttabheight); % FIXME Chapters should be counted within the part, thus keeping one chapter totvalue per part to adjust the chaptabheight in each part. \ifthenelse{\thechapcnt>0} { \pgfmathsetlengthmacro{\chaptabheight}{\parttabheight/\totvalue{chapcnt}} \pgfmathsetlengthmacro{\chaptaboffset}{(\thechapcnt-1)*\chaptabheight} \fill[green] ($(current page.north \corner)+(\sign.20,-\parttaboffset-\chaptaboffset)$)% rectangle ++(\sign.40,-\chaptabheight); }{} \end{tikzpicture} } \newcommand*{\unpart}[1]{ \part*{#1} \stepcounter{partcnt} \setcounter{chapter}{0} \setcounter{chapcnt}{0} \thepartcnt~\thechapcnt } \newcommand*{\unchapter}[1]{ \chapter*{#1} \stepcounter{chapcnt} \thepartcnt~\thechapcnt } \begin{document} \unpart{FirstPart} \unchapter{P1:FirstUNChapter} \section{A Numbered Section} \section{Another Numbered Section} \unchapter{P1:SecondUNChapter} \chapter{P1:ThirdNChapter} \stepcounter{chapcnt} \thepartcnt~\thechapcnt \unchapter{P1:LastUNChapter} \unpart{SecondPart} \unchapter{P2:FirstUNChapter} \unchapter{P2:SecondUNChapter} \unchapter{P2:ThirdUNChapter} \end{document} In the fourth page below the green rectangle is drawn outside of the blue rectangle because it's using 3 as the total number of chapters. The last part hast 3 chapters but the first one has 4. The chaptabheight of the chapters in the first part should be computed using 4, and the chaptabheight of the chapters in the second part should be computed using 3.

In the following Minimal Working Example (MWE), the section and subsection title formats are modified using titlesec's titleformat along with tikz. In order to handle odd and even pages, command sectitleformat receives arguments #6 and #7, which are {\innermargin}{\outermargin} for odd pages and {\outermargin}{\innermargin} for even pages. Is it possible to avoid defining and using \innermargin and \outermargin, and instead know/compute those margins using tikz's calc/positioning without explicitly passing those two arguments to sectitleformat? So, instead of using sectitleformat four times, I'd like to use it twice only (\sectitleformat[]... and \sectitleformat[numberless]...). \documentclass[twoside,openright,11pt]{report} \usepackage{geometry} \geometry{ showframe, a4paper, hmargin=18mm, bindingoffset=5mm, } \def\innermargin{\dimexpr\oddsidemargin+1in} \def\outermargin{\dimexpr\evensidemargin+1in\relax} \usepackage{MnSymbol} \usepackage{tikz} \usetikzlibrary{calc} \usepackage[explicit]{titlesec} \newcommand*\sectitleformat[7][]{ \titleformat{name=#2, page=#1}{\large\bfseries}{}{0pt}{ \begin{tikzpicture}[remember picture, overlay] \draw[draw=blue, thick] ($(current page.west|-0,0)+(#6,0)$) -- ++(#4,0) node [anchor=west] (S) {#3##1}; \draw[blue, thick] (S) -- ($(current page.east|-0,0)+(-#7,0)$); \end{tikzpicture} } } \newcommand*\sectitleformats[4]{ \sectitleformat[odd]{#1}{#2~$\filleddiamond$~}{#3}{#4}{\innermargin}{\outermargin} \sectitleformat[odd, numberless]{#1}{}{#3}{#4}{\innermargin}{\outermargin} \sectitleformat[even]{#1}{#2~$\filleddiamond$~}{#3}{#4}{\outermargin}{\innermargin} \sectitleformat[even, numberless]{#1}{}{#3}{#4}{\outermargin}{\innermargin} } \sectitleformats{\section}{\thesection}{.5cm}{fill} \sectitleformats{\subsection}{\thesubsection}{.75cm}{fill} \begin{document} \section{Numbered sec} \subsection{Numbered subsec} \section*{Numberless sec} \subsection*{Numberless subsec} \newpage \section{Another Numbered sec} \subsection{Another Numbered subsec} \section*{Another Numberless sec} \subsection*{Another Numberless subsec} \end{document}

I have searched this question, and have found so many, many different answers (a number of which I have tried unsuccessfully), that I feel as if it is the same as having no answer. What I am trying to do is fairly simple. I want every "normal" paragraph to be automatically and consecutively numbered through a document, eg, [1], [2]. By "normal" paragraph, what I mean is what would normally be a plain, unadorned paragraph from the body of a document that would be entered in most cases as plain text after a blank line. For example, my LaTeX source would look like this: \documentclass{article} \begin{document} \section{Section Heading} This is the first paragraph of my first section. It should have [1] at the beginning. This is the second paragraph of my first section. It should have [2] at the beginning. Following is a bullet list which should not be numbered: \begin{itemize} \item First list item \item Second list item \end{itemize} This is the third paragraph of my first section, should have [3] at the beginning. \subsection{Subsection Heading} This is the first paragraph of my first subsection. It should have [4] at the beginning. Here is a quote which should not be numbered: \begin{quote} This paragraph is a quotation from somewhere else. \end{quote} This is the next paragraph of my first subsection. It should have [5] at the beginning. \section{Another Section} This is the first paragraph of my second section. It should have [6] at the beginning. And so on. \end{document} Some of the code I've tried numbered EVERYTHING, including title pages, TOC, footnotes, captions etc. etc. However, I ONLY want the regular paragraphs numbered this way. What I want the output to look like is this: Section Heading [1] This is the first paragraph of my first section. It should have [1] at the beginning. [2] This is the second paragraph of my first section. It should have [2] at the beginning. Following is a bullet list which should not be numbered: First list item Second list item [3] This is the third paragraph of my first section. Subsection Heading [4] This is the first paragraph of my first subsection. It should have [4] at the beginning. Here is a quote which should not be numbered: This is the quotation. [5] This is the next paragraph of my first subsection. It should have [5] at the beginning. Another Section [6] This is the first paragraph of my second section. It should have [6] at the beginning. And so on. An example of what I want is Canadian court decisions, which usually look like this: https://www.canlii.org/en/on/onscdc/doc/2026/2026onsc3525/2026onsc3525.html If there is a simple answer to this that I have missed, would be much appreciated! Thanks

I need a reliable tool or compilation hook that can preprocess and flatten index.tex into a single, monolithic .tex file reflecting exactly what the compiler sees in memory before typesetting begins. The file index.tex uses \input and \subimport on documents which in turn could also pull in other latex files. Tool has to support \input and \subimport but \include is not needed as not used. Standard lightweight parsing scripts like flachtex or latexexpand or latex-flatten fail because they either do not support \subimport or do not hook into the system's active TeX Live binaries (like kpsewhich) to resolve paths to find the \input Instead, they force messy file system workarounds like manual folder flag passing or symbolic links, which is terrible software design and unmaintainable. Is there a robust, native preprocessor script or an engine hook (e.g., via LuaLaTeX or latexmk) that relies on the actual TeX Live environment variables to completely inline all inputs, sub-imports, and path-resolved dependencies into a single output file? Compiling the flattened index.tex should give the same PDF file as the original un-flattened index.tex. lualatex on texlive 2026. Update Here is an example folder_A/index.tex \documentclass[12pt]{article} \usepackage{import} \usepackage{standalone} \usepackage{amsmath} \begin{document} \input{A.tex} %<--- this is on $TEXINPUTS path somewhere TEXT 1 \subsimport*{./my_child/}{B.tex} TEXT 2 \end{document} and folder_A/my_child/B.tex is \documentclass[12pt]{article} \usepackage{amsmath} \begin{document} $ \sin x = 0$ some other text \end{document} and A.tex somewhere on $TEXTINPUTS path is This text from A.tex file \begin{align*} A &=B \end{align*} index_flatten.tex should be the following \documentclass[12pt]{article} \usepackage{import} \usepackage{standalone} \usepackage{amsmath} \begin{document} This text from A.tex file \begin{align*} A &=B \end{align*} TEXT 1 $ \sin x = 0$ some other text TEXT 2 \end{document} Command to do the above should use $TEXINPUTS and $TEXMFHOME to find \input files. so only need to do flatten_everything index.tex > index_flatten.tex

I'm trying to typeset an English document which contains the following text: The first of these Chinese characters is really problematic, and I've yet to identify a font which contains it. It is Unicode code point U+2B4DE (𫓞), which is an obscure, archaic character in the CJK Unified Ideographs Extension C block. It's normally replaced with 林 (U+6797) today, but I want to use the original character at least on the first use. Is anyone aware of a font that contains this sort of obscure characters? I typically use Noto Serif SC (or TC) when embedding fragments of Chinese in English text, and it's pretty good, but it doesn't seem to support this character. If not, is there any way of assembling the character manually from the 金 signific and 林 and 㐭 radicals which make it up, either in LaTeX or, possibly better, at a Unicode level using combining characters somehow? This question is not a duplicate of ‘Why doesn't my Chinese character display properly?’. I know why it doesn't display: my font doesn't support it. I'm also familiar with the solutions to that question: namely, to try a different font, in one of several different ways. What I'm looking for is either (a) a recommendation for a font that has sufficient coverage, or (b) a technique for composing the character manually from its individual radicals. Neither of those topics are addressed in that question.

Is there a built-in mechanism in plain TikZ to cache intermediate calculations locally within a plot expression? I mean I could just use a foreach loop and pgfmathsetmacro, but that's quite intensive. Is this built in to plot? If not, should/could it be? \documentclass{article} \usepackage{tikz} \begin{document} \tikz \draw[domain=0:1] plot ( \x, { (\x-2)^2 % there is an (\x-2) term here - (\x-2)^3 % and it is duplicated here } ) ; \end{document}

I am encountering issues when trying to make an environment with the tcolorbox package that creates a vertically-aligned in-line box enclosing an itemize environment. The purpose was to mimic an \fbox around an itemize in a minipage (hence the prescribed width). Below is code for a MWE: \documentclass{standalone} \usepackage{tcolorbox} \usepackage{enumitem} \newenvironment{mybox}[1] { \begin{tcolorbox}[ on line, left=0em, right=0em, top=0em, bottom=0em, box align=center, width=#1, ] \begin{itemize}[ nosep, leftmargin=*, labelsep=0em, ] }{ \end{itemize} \end{tcolorbox} } \begin{document} This text is slightly above the centre of the box \begin{mybox}{3cm} \item True \item False \end{mybox} \end{document} However, there appears to be some misalignment with the outside text, as if there is additional space placed above the tcolorbox. Compare with the minipage method: \fbox{\begin{minipage}{3cm} \begin{itemize}[ nosep, leftmargin=*, labelsep=0em, ] \item True \item False \end{itemize} \end{minipage}}

I'm using tkz-euclide to draw the following diagram, which is not properly centered: \documentclass{article} \usepackage{tikz} \usepackage{tkz-euclide} \begin{document} \begin{tikzpicture} \tkzDefPoints{0/0/A, 5/0/B} \tkzCalcLength(A,B) \tkzGetLength{dAB} \tkzDefCircle[R](A, 0.4*\dAB) \tkzGetPoint{P1} \tkzInterLC(A,B)(A,P1) \tkzGetPoints{}{C} \tkzDefCircle[R](B, 0.4*\dAB) \tkzGetPoint{P2} \tkzInterLC(A,B)(B,P2) \tkzGetPoints{D}{} \tkzInterCC(A,C)(C,A) \tkzGetPoints{E}{} \tkzInterCC(D,B)(B,D) \tkzGetPoints{F}{} \tkzInterLL(A,E)(B,F) \tkzGetPoint{G} \tkzDrawSegment[thick](A,B) \tkzDrawArc[gray, delta=10](A,C)(E) \tkzDrawArc[gray, delta=10](B,F)(D) \tkzDrawArc[gray, delta=10](C,E)(A) \tkzDrawArc[gray, delta=10](D,B)(F) \tkzDrawSegments[gray, add=0 and .1](A,G B,G) \tkzDrawSegments[thick, blue](A,G B,G) \tkzLabelPoint[below left](A){$A$} \tkzLabelPoint[below right](B){$B$} \tkzLabelPoint[below left](C){$C$} \tkzLabelPoint[below right](D){$D$} \tkzLabelPoint[above left](E){$E$} \tkzLabelPoint[above right](F){$F$} \tkzLabelPoint[above](G){$G$} % \tkzDrawPoints(P2) % \draw[red] (current bounding box.south west) rectangle (current bounding box.north east); \end{tikzpicture} \end{document} Uncommenting the code at the bottom shows the issue is with the point P2: It's only used for calculation and not drawn, but the bounding box is drawn to include it anyway, pushing the diagram left. Is there a way to instruct tikz to ignore this point so the diagram is centered appropriately? Is there a better way to use tkz-euclide to avoid this issue?

\hfill does not seem to work correctly with the typewriter font. In the example below, if I comment out \renewcommand{\familydefault}{\ttdefault}, the date is aligned flush with the right margin, as expected. However, when I switch to the typewriter font, it no longer reaches the right margin. Am I missing something? \documentclass[12pt,a4paper]{article} \usepackage[margin=4cm]{geometry} \usepackage{lipsum} \renewcommand{\familydefault}{\ttdefault} \begin{document} \bigskip\bigskip \hfill New York, 23 July 2026 \bigskip \lipsum[5][4-6] \end{document} Compare the two figures:

I wrote some install script for texlive using of course tlmgr under the hood. Nowhere I can find a documentation comprising return values also. I tried to analyze the script.. but was not really sure about the results. A link to documentation would be helpful since maybe even tlmgr may evolve. Reviewing the code, roughly speaking, the return value must be read in terms of bits $F_WARNING = 1 (Bit 0) $F_ERROR = 2 (Bit 1) $F_NOPOSTACTION = 4 (Bit 2) I think in most cases $F_ERROR bit set signifies an error, accordingly $F_WARNING set indicates a warning and $F_NOPOSTACTION... well I cannot figure out what a post action is. I am not quite sure about my analysis is really valid in any case and I dont know what a postaction is. Maybe someone reads this who is able to add a piece of documentation.

What I have: A master's dissertation written in LaTeX on Overleaf. It already have figures with custom definitions, and the caption show the correct name. However, they are all listed as "Figura N" on their respective lists, instead of using the custom name they show on the captions.

I am using titlesec/titletoc to give my article a section type \subpart between \section and \part. But there's an alignment problem with the page number in the table of contents, which makes three-figure page numbers cause an overfull hbox. Would be very grateful for some assistance. Attempted MWE below. N.B.

I am using context --export=yes to generate structural XML from my TeX documents to process later via saxon and XSLT. While the math display equations render perfectly in the PDF output, the generated XML flattens multiple formulas into one single continuous string, completely discarding row-break data. This makes it not possible to write an XSLT template to generate HTML since there is no XML tag to tell XSLT where to start new formula when there are multiple formulas as in this example. Source Example: \setupbackend[export=yes] \starttext \startformula \sin x \alignhere = B \breakhere A \alignhere = C \stopformula \stoptext The pdf is The XML generated <formula> <formulacontent image="1-image-exported-1" n="1"> <math data-lmtx-blob="1" data-lmtx-meaning="sin 𝑥 equals 𝐵 times 𝐴 equals 𝐶" display="block" displaystyle="true" xmlns="http://www.w3.org/1998/Math/MathML"> <mrow> <mi>sin</mi> <mi>𝑥</mi> <mo>=</mo> <mi>𝐵</mi> <mi>𝐴</mi> <mo>=</mo> <mi>𝐶</mi> </mrow> </math> </formulacontent> </formula> Notice that \breakhere is completely gone. converting this to HTML via saxon and xslt, the two formulas will show on one line, since there is no XML tag to tell where the breakhere is to guide the HTML generation. Is there a clean native configuration, an engine hook, or a specialized math function map in LMTX that tells the export processor to structure separate equation lines using custom XML hooks or native MathML container structures (like <mtr> and <mtd>)? I prefer not to use matrices because they alter math font character spacing properties. I worked on this with google AI for 2 hrs and we could not find solution.

I came here from another question. After adopting the solution an answer, using zhnumber, titlesec, and ctex, I can create headings that employ Chinese (Traditional, but shouldn't matter here) numerals such as 壹、這是第壹章 instead of 1 這是第壹章 However, while this works for section-level headers in the body of the document, it is not reflected in the Table of Contents. Is there a way to fix this? For reference I use Overleaf, XeLaTeX, and the xeCJK package.

Let's consider the following three examples: Example1. with newtx: \documentclass{article} \usepackage{newtx} % \usepackage{newtxtext} % \usepackage{newtxmath} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} Both the number in text or math was turned "Times": Example2. with newtxtext: \documentclass{article} % \usepackage{newtx} \usepackage{newtxtext} % \usepackage{newtxmath} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} Only the text was turned "Times", and that was the expected behaviour. Example3. with newtxmath: \documentclass{article} % \usepackage{newtx} % \usepackage{newtxtext} \usepackage{newtxmath} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} That was confusing for me, if and only if newtx was loaded, the numbers in math would be changed to "Times"-style, that was out of my expectation. Is the behaviour of newtxmath that didn't change the number in math that expected and how can it be changed?
