I am using the book class. My main file includes the following toc styling commands: \documentclass{book} \usepackage{nonumonpart} \usepackage{tocloft} \usepackage{calc} \usepackage[titletoc,title]{appendix} \renewcommand{\cftpartfont}{\LARGE\bfseries} \renewcommand{\cftchapfont}{\large\bfseries} \setlength{\cftchapnumwidth}{1.1875in}\renewcommand{\cftchappresnum}{Chapter }\renewcommand{\cftchapaftersnum}{:\phantom{mm}}\cftpagenumbersoff{part}\renewcommand\cftchapafterpnum{\par\addvspace{6pt}} \setlength{\cftbeforepartskip}{17pt} Borrowing from Werner's answer here. I included the following code to change the ToC's printing from "Chapter" to "Appendix": \let\oldappendix\appendix \renewcommand{\appendix}{% \oldappendix \addtocontents{toc} % Update \cftchappresnum within the .toc {\protect\renewcommand{\protect\cftchappresnum}{\appendixname\space}} } \renewcommand{\contentsname}{\underline{Table of Contents}}\setlength\cftbeforetoctitleskip{24pt}\setlength\cftaftertoctitleskip{24pt} \begin{document} ... \include{ch12} \appendix \pagenumbering{arabic} \renewcommand\thepage{A\arabic{page}} \include{appendixA} \pagenumbering{arabic} \renewcommand\thepage{B\arabic{page}} \include{appendixB} \end{document} It changes for Appendix B but not Appendix A: Does anyone know why it's not overriding the "Chapter" for Appendix A, and/or how to change that?

I’ve found that the secret behind BaKoMa’s incremental compilation seems to be hidden in itex.dll, which is located in the BaKoMa installation directory. There’s a reverse-engineering repository available at https://github.com/morluto/rea. Has anyone tried using Claude or ChatGPT to help implement incremental compilation?

I want to write bold and italic letters for math vectors. I found on here that the \bm package would handle this. And it does but the letters look like this: This is when I'm writing \bm{\dot{x}(t)}. This project is the first time I'm using LaTeX locally and not in Overleaf. Any idea why it looks like multiple instances on top of each other?

I want to typeset the moves of a game in two columns in the following way. e4 e5 Nf3 Nf6 I know how to typeset, for instance 1... e5. I want to know how to typeset e4 ... I need three dots insted of the black move. Can anyone help me? Thanks a lot.

I am looking for a way to highlight the end of a mathematical calculation. Not to say it's important, like \boxed does, but merely to clarify what one has ended with. See the red in the following image: So it can be translated to the following (considering \asresult{} draws the red line as above): \documentclass{article} \usepackage{amsmath, tikz} \newcommand{\diff}{\mathrm{d}} % differential pebble \newcommand{\asresult}[1]{ % result highlight %... } \begin{document} The derivation of the derivate of the exponential, under such new tools, needs a re-route first: \begin{align*} e^{\diff x} &= \sum_{k=0}^\infty \frac{\diff x^k}{k!} \\ &= \asresult{1 + \diff x} \\ (\diff e^x)(t) &= \lim_{h \to 0} e^{x(t+h)} - e^{x(t)} \\ &= e^{x(t)} \lim_{h \to 0} e^{x(t+h) - x(t)} - 1 \\ &= e^{x(t)} (e^{\diff x(t)} - 1) &= \asresult{e^{x(t)} \diff x(t)} \end{align*} And with that, one deduces $\cfrac{\diff e^x}{\diff x} = e^x$, QED. \end{document} How can I add this \asresult?

How can I link a part toc into the part header page? I am trying to implement part specific and chapter specific toc on their relative title headers. The code for the chapter toc is based directly on pp 414-417 of memman.pdf and works well. I (naively) thought that repeating the code but replacing chapter with part would result in a corresponding part toc. My implementation of this does not seem to hook the part and the toc together. The attached code shows the wanted main toc, and chapter specific toc; but does not show the part toc. I expected a toc very similar to that for chapter on the title page. My example below shows the code for the chapter and the part toc. The part toc portion has been bounded by &**********. I have removed a lot of code concerning toc formatting, so the formats may be off. To aid me I have used: memoir: Chapter TOCs (Part 1) memoir: Chapter TOCs (Part 2) memoir: Chapter TOCs (Part 3) These have been very helpful, but when they venture into Tex code, rewriting parts of memoir, and @ symbols and the like, they are way above my competence. \documentclass{memoir} \usepackage{lipsum} \makeatletter \newcounter{tocmarker} \renewcommand\mempreaddchaptertotochook{\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand\mempreaddparttotochook {\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand{\mempostaddchaptertotochook}{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth \newcommand\chaptertoc{ \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}} \let\changetocdepth\@gobble \normalchangetocdepth{-10} \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{2}} \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}} \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}} \par\bigskip \@afterheading } %******************************* \renewcommand\mempostaddparttotochook{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth % for later \newcommand\parttoc{ \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}} \let\changetocdepth\@gobble \normalchangetocdepth{-10} \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{1}} \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}} \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}}% \par\bigskip \@afterheading } \makeatother %******************************* \begin{document} \tableofcontents* \part{Rewrite v2} \parttoc \chapter{Chapter} \chaptertoc \section{Section} \lipsum \end{document}

For certain reasons I have to use TeXShop version 3.62 in a project. It works fine with Sequoia 15.7.7, but will it work if I upgrade to Tahoe?

Good evening everyone, I am facing a problem when I designate crystallographic faces with the Miller notation (via the miller package). Typing the following code: \documentclass[varwidth=15cm, border=1pt, 11pt]{standalone} \usepackage{amsmath} %\usepackage{physics} \usepackage{fontspec} \usepackage{miller} \setmainfont{STIX Two Text} \usepackage[math-style=upright,mathbf=text,mathbf=sym,mathrm=text,mathrm=sym]{unicode-math} \setmathfont{STIX Two Math} \begin{document} \begin{equation*} \hkl(110)\equiv\hkl(11-20) \end{equation*} \end{document} Leads me to this: I am struggling in getting the bar over the "2" closer to the number. Can the distance between these two be set? Thank you in advance for your help.

The folarrow package, available for amscd, xy-pic, and tikz-cd, provides the possibility of placing a marking or description at the center of the arrow's tail. I wonder whether it is possible to obtain markings of the same size, both for the tail and the arrow, with one, two, or four bars, similarly to the three-bar marking provided by folarrow. \documentclass{article} \usepackage{tikz-cd,amssymb} \usepackage{folarrow} \begin{document} \begin{tikzcd} A \arrow[r, foliated] \arrow[rd, "\smallsetminus" marking] & B \arrow[d, "///" marking] \\ & C \end{tikzcd} \end{document}

Here is a MWE where the caption of a longtable is being tagged as a table row (TR) and as a header row (TH) using lualatex (and lualatex-dev) with tagging=on. This leads to Regularity errors in the Adobe Acrobat checker. [I'm running the latest MikTeX updates with latex-tools updated as well.] Am I doing something incorrectly, or is there a longtable conflict with the tagging tools? It's listed as compatible at latex3.github.io/tagging-project/tagging-status/.

The following picture shows what I want. I add cbx:cnparens to replace cbx:parens. But maybe I don't replace all of cbx:parens, then which are not replaced? By the way, don't change other cite commands, such as \cite and \cites. Note that caspervector-ay bases on authoryear-comp.

Is there a way to get an abbreviation label centered over an AVM like the D over the AVM in the SPR list shown here? The code I had to do this using the AVM package was as follows (and admittedly I don't really understand it and usually just copy pasted it): \begin{avm} \avml\hfil D \\[-1ex] \[ COUNT & $+$ \\ \] \avmr \end{avm}

The example in 2. Introduction on page 5 of the xskak document suggests to define variations as alternatives to a move defined in the starting board, as for example 3...a6 being a kind of standard first Black move in the Ruy Lopez, and 3...Bc5, 3...Nd4, etc. being variations of it. While this works, it is somewhat illogical. Who is to say which one of the possibilities is to be regarded the "standard" first continuation move? Also, the situation becomes increasingly messy as one progesses down the tree of moves and has to deal with nested variations. Attempting not to define the initial "standard continuation" as in \mainline{1.e4 e5 2.Nf3 Nc6 3.Bb5} leads to the error: White, not Black to move (a6). Purely by chance I found that \mainline{1.e4 e5 2.Nf3 Nc6 3.Bb5 *} or putting some other character where Black's first move should be, improved the issue but needs fixing by getting rid of the spurious ZZ*.

Looking over many examples of LaTeX code in macro definitions, I often find a % at the end of a line --- so that no extraneous spaces are somehow imported into the macro by the end of line character. However, at the same time, I notice that these same macros often have many lines starting wit indentations --- presumably to make the code readable. How come the code can be indented at all? Why should every line in the macro have any opening spaces at all? Isn't the point of % to avoid extraneous spaces? Why do we care about that at the end of the line, but do not care about it at the beginning of the line?

I have updated MikTex, and now I get this error when I compile my tex files with pdflatex: ! Use of \??? doesn't match its definition. <argument> \??? ! Latex Error: Misplaced '=' in key-value input on line 59. The pdf file produced looks good, it has the hyperlinks that I expect. When I comment out the hyperref package, no error is thrown, but then of course, the expected hyperlinks the hyperref package produces are not there. I have found a post referring to a similar issue, where a re-installation has solved the problem. However, this did not work for me. Here is a minimum working example: \documentclass[a5paper,fontsize=9pt, twoside, DIV=17, BCOR=1mm]{scrbook} \usepackage [bookmarks, colorlinks=true, linkcolor=blue, citecolor=magenta, urlcolor=cyan, pdfpagelayout=TwoPageRight, pdfpagelayout=SinglePage, pagebackref, pdfusetitle ] {hyperref} \usepackage[chorded, noshading]{songs} \baselineadj=-1.8ex plus 0.3ex minus 1.0ex \versesep=0.5ex plus 0.5ex minus 0.5ex \renewcommand{\colbotglue}{0pt plus .5\textheight minus 0pt} \songpos{3} \settowidth{\versenumwidth}{10.} \setlength{\songnumwidth}{7.5ex} \newcommand{\sieben}{\textsuperscript{7}} \begin{document} \chapter{Preface} \label{label} \chapter{Songs} \begin{songs}{} \beginsong{The drunken sailor} [ by = {Traditional} ] \beginverse \[d]What shall we do with the drunken sailor, \[C]what shall we do with the drunken sailor, \[d]what shall we do with the drunken sailor \[C]early in the \[d]morning? \endverse \beginchorus \[d]Hooray!

LaTeX Error: Misplaced '=' in key-value input on line 59 l.59 \endsong If you say, e.g., `\def\a1{...}', then you must always put `1' after `\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it. Any ideas for a fix or a workaround? Thanks in advance for your help!

This post is similar to this one, but not exactly the same... With the following code: \documentclass{article} \usepackage{amsmath} \usepackage{tikz} \usetikzlibrary{matrix} \setlength{\fboxsep}{0pt} \begin{document} \[ \begin{tikzpicture} \matrix (magic) [ matrix of math nodes, nodes={circle,draw=magenta,minimum size=1cm}, left delimiter=(, right delimiter=) ] { 1 \\ & 1 \\ & & \ddots \\ & & & \fbox{$\ddots$} \\ & & & & 1 \\ }; \draw[teal,dashed] (magic-1-1.center) -- (magic-5-5.center); \end{tikzpicture} \] \end{document} What I want was the following: only typeset three dots, thus \Ddots with nicematrix was not so flexible; I want the "slope" of \ddots was parallel with the teal,dashed line; I want to ellnimate the extra height of the bounding box of \ddots(why?It looks not good...) It recalled the classical \rvdots here, and we know: $ latexdef \ddots \ddots: macro:->\protect \ddots \ddots : macro:->\mathinner {\mkern 1mu\raise 7\p@ \vbox {\kern 7\p@ \hbox {.}}\mkern 2mu \raise 4\p@ \hbox {.}\mkern 2mu\raise \p@ \hbox {.}\mkern 1mu} I guessed slightly modify the commands could help?

I don't think it will look so good if the dots look different in different cases. at least, that is not how it usually would work in latex? \documentclass{article} \usepackage{amsmath} \usepackage{nicematrix} \usepackage{tikz} % \usepackage{kpfonts-otf} \begin{document} \[ \begin{pNiceMatrix} 3 & & & \\ & 555 & & \\ & & \ddots & \\ & & & 66666 \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix}\qquad \begin{pNiceMatrix} 3 & & & \\ & 555 & & \\ & & \Ddots & \\ & & & 66666 \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix} \] \[ \begin{pNiceMatrix} a & & & \\ & b & & \\ & & \ddots & \\ & & & d \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix}\qquad \begin{pNiceMatrix} a & & & \\ & b & & \\ & & \Ddots & \\ & & & d \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix} \] \[ \begin{pNiceMatrix} x & & & & \\ & x+y & & & \\ & & \ddots & & \\ & & & \sqrt{x-y} & \\ & & & & \dfrac{x}{y} \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix}\qquad \begin{pNiceMatrix} x & & & & \\ & x+y & & & \\ & & \Ddots & & \\ & & & \sqrt{x-y} & \\ & & & & \dfrac{x}{y} \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix} \] \end{document} With latin-modern-math: With kpfonts-otf:

I am using the luacas package to handle symbolic math and compute coordinates. Currently, to display the vector $\vec{AB}$ from two points $A$ and $B$, I have to subtract and print each component individually like this: \documentclass[12pt]{article} \usepackage{amsthm} \theoremstyle{definition} \newtheorem{ex}{Example} \usepackage{luacas} \usepackage{esvect} \begin{document} \begin{ex} \begin{CAS} A = {sqrt(2), -2/7, 3/5} B = {sqrt(8), -14/29, 3*sqrt(3)} \end{CAS} \[\displaystyle A=\left(\print{A[1]};\print{A[2]};\print{A[3]} \right), \quad B=\left(\print{B[1]};\print{B[2]};\print{B[3]} \right).\] \[ \vv{AB}=\left(\print{simplify(B[1]-A[1])};\print{B[2]-A[2]};\print{B[3]-A[3]} \right) .\] \end{ex} \end{document} This approach makes the code repetitive and messy. I would like to simplify the workflow by computing the vector directly within the CAS environment and printing it in one go, like this: \begin{CAS} A = {sqrt(2), -2/7, 3/5} B = {sqrt(8), -14/29, 3*sqrt(3)} vAB = B - A \end{CAS} \[\vv{AB} = \print{vAB}\] However, doing this directly does not work as expected. I got the massage: [string "A = {sqrt(Integer('2')), -Integer('2')/Intege..."]:1: attempt to perform arithmet ic on a table value (global 'B') stack traceback: [string "A = {sqrt(Integer('2')), -Integer('2')/Intege..."]:1: in local 'exe' ...26/texmf-dist/tex/lualatex/luacas/test/luacas-parser.lua:329: in function ' CASparse' [\directlua]:1: in main chunk. \luacode@dbg@exec ...code@maybe@printdbg {#1} #1 } l.15 \end {CAS} ? Is there a way to define a custom function, a macro, or use a specific luacas command/method so that I can compute $vAB = B - A$ (or simplify it) and print it cleanly without accessing each index manually?

The obvious way to typeset castling would be 0-0 (and 0-0-0 for long castling), but \chessboard shows no sign of it, and the move record shows ZZ0-0. I have tried all sorts of options, to no avail.

I'm compiling a document with make4ht (MathJax output) that contains several worked examples on indeterminate forms. In these examples, some exponents are themselves fractions or expressions, and I need to enlarge only those particular exponents, not all of them. The usual LaTeX approach — wrapping the exponent in \textstyle or \displaystyle — works fine with pdflatex, but has no effect when compiling with make4ht. Here is a minimal example: \documentclass[fontsize=18pt, paper=letter]{scrartcl} \usepackage{lmodern} \usepackage[T1]{fontenc} \usepackage{mathtools} \usepackage{amssymb,amsthm} \usepackage{latexsym,stmaryrd} \begin{document} $\displaystyle \lim_{u\rightarrow 0} \left(\dfrac{\sin u}{u}\right)^{\textstyle u^{-2}} $\\ $\displaystyle \lim_{u\rightarrow 0} \left(\dfrac{\sin u}{u}\right)^{\displaystyle u^{-2}} $\\ \end{document} I compile with: make4ht text.tex "mathml,mathjax,svg,Gin-dim" Questions: Is there a way to make make4ht preserve \displaystyle / \textstyle inside an exponent so MathJax honors it? If not, is there a recommended way (custom macro, MathJax config, CSS with a unique class, etc.) to enlarge a single exponent without affecting the rest? Is this a known limitation of make4ht's math handling? If so, is there a workaround that is robust across MathJax versions? I'm attaching two screenshots showing that the two formulas render identically despite the different style commands. Any help is appreciated. Thanks! This screenshot shows the PDF output generated with pdfLaTeX using TeX Live 2026 on Ubuntu Linux. As you can see, the exponent containing the limit is displayed at a reasonable size and is clearly readable. However, in the HTML output generated by make4ht, the same exponent appears considerably smaller after MathJax finishes rendering the expression. My goal is to make the HTML rendering look as close as possible to the pdfLaTeX output, particularly regarding the size of complex exponents. test.html https://wimate.org/test

Here's an other fun-competition: replicate the drawing below somehow (boy, kite, tree, i.e. WITHOUT the blue lines, intended for Mr. Pythagoras) describe your approach good enough so others can repeat it (at least try to) Forgot to put my thought in writing: Where somehow means including quite exact reproductions, as many of the first AI-answers showed, but not limited to. E.g. just using strokes would be fine as well. Use yor imagination. IF you use AI for code creation, please consider giving more, at least enough details. As indication see e.g. Explorer's answer, which improved and evolved via comments to add what's missing. Minimum I'd expect in this case: prompt (if it's just a single shot) history of prompts (if it was more an interactive work) AI-machine/-provider, AI-models used other tools used, like oh-my-pi etc. required setups etc. In the original post the drawing was included via graphicx, but wasn't uploaded. So let's take the opportunity to replicate it with your favorite approach for or with LaTeX.

Let's consider the following MWE \documentclass{report} \usepackage{cleveref} \begin{document} \appendix \chapter{Title}\label{t} This is a \namecref{t} \end{document} Now compile it using TeXLive 2026 and 2023. Then compare them. TeXLive 2026 TeXLive 2023 Well, I don't understand why in TeXLive 2023 (or 2022) appears appendix while in TeXLive 2024 and above is chapter. I also noticed another thing. Inspecting foo.aux I found \newlabel{t@cref}{{[chapter][1][]A}{[1][1][]1}{}{}{}} in TexLive 2026 \newlabel{t@cref}{{[appendix][1][2147483647]A}{[1][1][]1}} in TeXLive 2023 As always I compiled this MWE with latexmk -Werror -halt-on-error -file-line-error -lualatex ./foo.tex I tried also with -pdflatex but I got the same result.

I started learning (and using) LaTeX almost two years ago. But I see now that AI can produce the code for whatever I may want in a few seconds. This has demotivated me to continue learning more about LaTeX. Should I continue learning it ? If yes, why ? Just for the sake of enjoyment ? Or, are there more practical reasons ?

I have been using VS Code in order to type up my documents in Latex, and the terminal to compile/render them. In VS Code, I have various code snippets, such as "Real Numbers": { "prefix": "RR", "body": "\\mathbb{R}", "description": "Real numbers" }, that populate \mathbb{R} whenever I type RR. However, I could have also created a new command \RR in my tex file via \newcommand that does the same thing. I was wondering if y'all had any insight into when it would be better to use one over another. Question: Are there practical reasons to prefer using \newcommand over code fill snippets, or vice versa for certain applications?

I would like to add dimension arrows like the ones shown here. What is the most elegant way to do this in common? (Note that I am showing an example here; however, a good general method would be interesting.) So, for instance, the dimension arrows and labels should be placed evenly and systematically. Here is my own rather clumsy attempt: \documentclass[margin=5pt, tikz]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} %% Values \pgfmathsetmacro{\R}{2.0} \pgfmathsetmacro{\a}{1.9} \pgfmathsetmacro{\b}{sqrt(\R^2 - \a^2) + \R} \pgfmathsetmacro{\x}{\R+(sqrt(2)*sqrt(\R*(2*\R-\b)) +\b -2*\R)-\b} \begin{tikzpicture}[scale=1.5, font=\footnotesize, >={Triangle[length=0pt 2*4,width=0pt 4]}, ] %% Coordinates on the main segment \coordinate[label=below:$M$] (M) at (0,0); \coordinate[label=below:$O$] (O) at (-\R,0); \coordinate[label=below:$A$] (A) at (\R,0); \coordinate[label=below:$C$] (C) at (\R-\b,0); %% Draw main segment OA \draw[] (O) -- (A); %% Solution elements on the main segment \coordinate[label=below:$X$] (X) at (\x,0); % Dimension arrows \foreach \P in {C,M,X,A}{%% \path[draw=none, shorten <=1em] (\P) -- +(0,-1.125) coordinate[pos=0.3] (\P-1) coordinate[pos=0.6] (\P-2) coordinate[pos=0.8] (\P-3) coordinate[pos=1.0] (\P-4); }%% \draw[shorten <=1em] (X) -- (X-2); \draw[<->] (C-1) -- (X-1) node[midway, fill=black!1]{$r$}; \draw[shorten <=0.25em] (M-1) -- (M-2); \draw[<->] ([yshift=0.5em]M-2) -- ([yshift=0.5em]X-2) node[midway, below]{$x$}; \draw[shorten <=1em] (C) -- (C-4); \draw[shorten <=1em] (A) -- (A-4); \draw[<->] (C-3) -- (A-3) node[midway, fill=black!1]{$b$}; %% Draw points on the axis (solution) \foreach \P in {A, X} \draw[fill=black!1] (\P) circle (1.5pt); %% Draw points on the axis (task) \foreach \P in {C, M} \draw[fill=black!1] (\P) circle (1.5pt); \draw[fill=black!1] (O) circle (1.5pt); \end{tikzpicture} \end{document}
