When compiling context latex which has formula with equation number, the XML generated is missing the equation number. Is there a way to keep equation number in the XML? MWE \setupbackend[export=yes] \starttext \startplaceformula \startformula \startalign \NC A \EQ B \NR[eq:b] \stopalign \stopformula \stopplaceformula \stoptext The pdf from context 1.tex is Here is the XML <document context="2026.04.10 18:55" date="2026-07-27 14:37:47-05:00" file="1" language="en" title="1" version="0.36" xml:lang="en"> <formula> <formulacontent image="1-image-exported-1" n="1"> <math data-lmtx-blob="1" data-lmtx-meaning="𝐴 times group equals 𝐵 end group  " display="block" displaystyle="true" xmlns="http://www.w3.org/1998/Math/MathML"> <mrow><mrow><mi>𝐴</mi><mrow><mo>=</mo><mi>𝐵</mi></mrow><mtext/></mrow><mtext> </mtext></mrow> </math> </formulacontent> </formula> </document> Notice the mathml has lost equation number which is (1). What I mean is that there is no explicit XML tag for the equation number produced. Something like <formulatag>(1)</formulatag> Or such similar XML tag that goes with the mathml to help the XSLT sheet translate the formula with the equation number correctly. Putting the formula number is custom attribute "n=1" makes it hard to parse in XSLT compared to specific XML tag. mathml as far as I know do not support equation number built in (mlabeleddtr not supported anymore). So in place of this, context should generated explicit XML tag for this in place. texlive 2026 >context --version mtx-context | ConTeXt Process Management 1.06 mtx-context | mtx-context | main context file: /usr/local/texlive/2026/texmf-dist/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2026.04.10 18:55 mtx-context | main context file: /usr/local/texlive/2026/texmf-dist/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2026.04.10 18:55

How can I filter a spline surface by a plane in Asymptote? import graph3; unitsize(1cm); currentprojection = orthographic(0,2,1); // Function to generate a point on the unit sphere triple sphere(real azimuth, real polar) { return ( cos(polar) * cos(azimuth), cos(polar) * sin(azimuth), sin(polar) ); } // Helix function triple helix(real t) { return ( 2 * cos(t), // x-coordinate 2 * sin(t), // y-coordinate t // z-coordinate ); } // Define the helix path path3 thehelix = graph(helix, 0, 4*pi); draw(thehelix); // Helicoid function triple helicoid(pair uv) { real t = uv.x; real theta = uv.y; return ( helix(t).x + sphere(t,theta).x, helix(t).y + sphere(t,theta).y, helix(t).z + sphere(t,theta).z ); } // Create the surface of the helicoid surface thehelicoid = surface(helicoid, (0, -3pi/2), (4*pi, 0pi), Spline); draw(thehelicoid, surfacepen=material(white, emissivepen=0.2 white)); triple myplane(pair uv) { return ( uv.x, uv.y, uv.x+2*uv.y+5 ); } surface themyplane = surface(myplane, (-5, -5), (5, 5), Spline); draw(themyplane, surfacepen=material(white, emissivepen=0.2 blue)); I want to remove the the portion of the helix which is beyond the boundary of the half-space on one side of the plane.

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'm using fibeamer and it seems that some symbols (like \leqslant for instance) that seem not changed according to the font, that is, by comparing the symbol "<" with fibeamer font and the same symbol with regular font (Computer Modern I presume), there are differences. However, the same does not occur with \leqslant. There is a way to overcome this?

I was just wondering what LaTeX package (if it's LaTeX at all) the following large straight parentheses and vertical integral symbols are from.

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.

When I try to put a tikzpicture inside a marginnote, I get this error: Equations.tex: error: 132: Argument of \pgfplots@addplotimpl@expression has an extra }. I guess there may be a conflict with another package/options as when I try a MWE with just the marginote, it works, see below. I cannot paste here my whole preambule as it would be too long. What could a possible source of this error? (For context I'm trying to get something similar as can be seen in this discussion. Sadly the code is nowhere to be found in the discussion...) \documentclass[a4paper,11pt]{article} \usepackage[top=2cm,bottom=2cm,right=4cm,left=2cm,marginparsep=0.5cm]{geometry} \usepackage{marginnote} %%%Tikz \usepackage{tikz} \usepackage{pgfplots} \begin{document} A marginote, all good \marginnote{ \begin{tikzpicture} %[x=1cm,y=1cm,auto,rotate=90,transform shape] \begin{axis}[ width=4.5cm, height=3cm, % hauteur xmin=-2, xmax=10, ymin=0, ymax=12, xtick= \empty, ytick= \empty, extra x ticks = {0,2}, extra x tick style={tick style={draw=none}}, extra y ticks = {2, 8,10}, extra tick style={tick style={draw=none}}, axis line style={thick, shorten >=-20pt, shorten <=0pt}, %extra x tick labels={0,0.5,...,10}, %grid style={very thin, dotted, color=gray}, grid=none, % grille verticale et horizontale axis x line=center, axis y line=center, ylabel=$x(t)$, ylabel style={anchor=south,yshift = 0.75cm}, xlabel=$t$, xlabel style={anchor=west,xshift = 0.75cm}, axis line style={>=stealth,->}, ] \addplot+[domain=0:10,color=cyan, thick, smooth,samples=400,mark=none] (\x,{4/(1+5^(-2*\x))}); \addplot+[only marks,mark = *, cyan, mark options={fill=white} ] coordinates { (2,5) (0,4)}; \draw [dashed, cyan] (axis cs:{2,0}) -- (axis cs:{2,5}) -- (axis cs:{0,5}); \draw [dashed, orange] (axis cs:{0,10}) -- (axis cs:{10,10}); \end{axis} \end{tikzpicture}} But does not work \end{document} Edit: The solution was here, the key was to use \shorthandoff. I'm not sure why and what this command does though, so the solution may not be robust.

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.

I am using ConTeXt ver: 2026.04.27 13:56 LMTX fmt: 2026.5.12 int: english/english on \setupinteraction[state=start,focus=standard] \definereferenceformat[zcref][label=reference:*] \setuplabeltext [en] [reference:section=Section~, reference:formula=Formula~] \setuphead [section] [textstyle=\bf, bodypartlabel=ABC, ] \starttext \startsection [title=Math, reference=sec:math] We want to refer to \zcref[sec:math]. \startformula 1 + 1 = 2 \numberhere[eq:one] \stopformula See \zcref[eq:one]. \stopsection \stoptext In particular, I use the option bodypartlabel=ABC to edit the label printed. However, there is no ABC on the PDF. Could you explain on this phenomenon? How can we check if the option bodypartlabel is deprecated?

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}

TeXstudio 4.9.5 (git 4.9.5) When using QT version 6.11.0 and compiling with Qt 6.11.0 R, the following error message appears. What is the solution?

When compiling to HTML I need to use \begin{Verbatim} TEXT \end{Verbatim} And when compiling to PDF, I need to use an environment defined using listing, called TEXTinline The thing is, I do not want to duplicate TEXT and do this \ifdefined\HCode \begin{Verbatim} TEXT \end{Verbatim} \else \begin{TEXTinline} TEXT \end{TEXTinline} \fi The above works, but it means I have to duplicate TEXT which can be very large in 2 places in the latex file. I'd like to just do \begin{myBOX} TEXT \end{myBOX} And inside the myBOX envi, it does the selection as earlier. The problem is that \if ....\else...\fi can not be inside \newenvironment{myBox} definition. Tried but could not make it work. So do not know what to do. Here is MWE with another attempt which also do not work \documentclass[12pt]{article}% \usepackage{listings} \usepackage{fancyvrb} \lstdefinestyle{TEXT}{% basicstyle=\ttfamily\small, breaklines=true, columns=fullflexible } \lstnewenvironment{TEXTinline}{% \lstset{style=TEXT}}{} % THIS DOES NOT WORK \ifdefined\HCode \newenvironment{myBox}{ \begin{Verbatim} }{ \end{Verbatim} } \else \newenvironment{myBox}{ \begin{TEXTinline} }{ \end{TEXTinline} } \fi \begin{document} \begin{myBox} I want to draw 3 cubes \end{myBox} \end{document} Using lualatex for PDF.

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:

Consider the code: \documentclass[12pt]{book} \usepackage{scalefnt,color,yfonts} \usepackage[many]{tcolorbox} \begin{document} \thispagestyle{empty} {\color{red} \scalefont{2.00}{\textbf{\textsl{TITLE1}}}}\\[20pt] \scalebox{1.87}{\textbf{\textgoth{\Huge{Title2}}}} \tcbox[colback=yellow,width=0.75in,height=1.25cm]{Inline tcolorbox} \end{document} which produces QUESTION: How may I place the tcolorbox inline to the right of the second title? (I thought \tcbox would do that.) Thank you.

What I have: A master's dissertation written in LaTeX on Overleaf, using the document class ABNTeX2. It already have equations, declared as such: \documentclass[ 12pt, oneside, a4paper, english, spanish, esperanto, brazil, ]{abntex2} \usepackage{amsmath} \begin{document} \begin{equation} R^2 = 1 - \frac{\sum_{i=1}^{n} (\text{Real value}_i - \text{Predicted value}_i)^2}{\sum_{i=1}^{n} (\text{Real value}_i - \text{Average value})^2} \label{eq:r2} \end{equation} \end{document} What I need: I need that equations like that be automatically listed by a \listofequations command like a list of tables or a list of figures. The equations must have a name set up when they are declared, so something meaningful can be shown on the list instead of the equation LaTeX code.

By compiling the following code via Lua LaTeX, I get the message: ! LaTeX Error: Command `\eth' already defined. My code is: \documentclass[a4paper,12pt]{report} \usepackage{unicode-math} \setmainfont{Carlito} \setmathfont{LeteSansMath} \usepackage{amssymb} \usepackage{latexsym} \usepackage{amsmath} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage[mathscr]{eucal} \usepackage{verbatim} \usepackage{graphicx} \usepackage{fancyhdr} \usepackage{fancybox} \usepackage{array} \usepackage{bm} \usepackage{a4wide} \usepackage{enumitem} \usepackage{lipsum} \begin{document} \lipsum \end{document}

I'm using Carlito font, but in math mode, the not equal sign (\neq) seems to have the vertical bar displaced to the right. I wonder, how this can be fixed?

I’ve looked but haven’t found a package that provides it; I know it’s not exactly standard notation, but I use it regularly and would like to have it in LaTeX.

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?

I'm testing a manuscript for LaTeXML compatibility ahead of submission to the arXiv, and I've run into the following curious issue with tikz-cd when compiled in LaTeXML. In short, node names involving the \overline command are systematically misaligned—in particular, the horizontal misalignment of overlined nodes, especially when their names are longer, is extremely disruptive. Here's a minimal example illustrating this behaviour: \documentclass{article} \usepackage{tikz-cd} \begin{document} % both node names are centered \[ \begin{tikzcd} Q \\ R \arrow[from=1-1,to=2-1] \end{tikzcd} \] % the name of node 1-1 is now right- and bottom-aligned \[ \begin{tikzcd} \overline{Q} \\ R \arrow[from=1-1,to=2-1] \end{tikzcd} \] \end{document} Here are screencaps of the resulting diagrams side by side: I'm hoping there's a quick workaround for this behaviour. My manuscript involves a number of commutative diagrams where \overline is used repeatedly, some of which are quite large. Note that the above code compiles perfectly in LaTeXML without any errors or warnings. EDIT: For whatever it's worth, here's what you get from the following code: \[ \begin{tikzcd} \overline{Q} & Q \\ Q & \overline{Q} \arrow[from=1-1,to=2-1] \arrow[from=2-1,to=2-2] \arrow[from=1-1,to=1-2] \arrow[from=1-2,to=2-2] \end{tikzcd} \] EDIT 2: The same diagrams but with \tikzcdset{nodes=draw, every diagram/.append style={baseline=(\tikzcdmatrixname-1-1.base)}} as suggested: EDIT 3: For the morbidly curious, here's an example of the actual misery I'm trying to fix:
