By using nicematrix package and command \Block, I'm struggling to reduce the width and height of block colors, separately. Any hint? Below, find the code: \documentclass{article} \usepackage{nicematrix,tikz} \begin{document} \begin{equation*} \begin{bNiceArray}{cccc|c}[columns-width=5pt,margin] \Block[fill=red]{2-4}{} a_{11} & a_{12} & a_{13} & a_{14} & \Block[fill=yellow]{3-1}{} a_{15} \\ a_{21} & a_{22} & a_{23} & a_{24} & a_{25} \\ a_{31} & a_{32} & a_{33} & a_{34} & a_{35} \end{bNiceArray} \end{equation*} \end{document}

I'd like to use a pgfplots axis environment to render some plots. I'd like them to be aligned with the surrounding TiKz graphics. However, I have not yet managed to find the correct options. I'm also only interested in the plotted line itself, so no ticks or axes need to be drawn in addition. So far I have this (failed) example. My goal would be aligning the coordinate system the axis environment such that the two curves are right on top of each other. With the width/height I assumed I could set the exact dimensions, but that already seems to be off. Is there a way to modify this axis-environment to match the coordinate system of the tikzpicture-environment? \documentclass{standalone} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture} \draw[lightgray] (-2, -3) grid (4, 4); \fill[lightgray] (0,0) circle (0.2); % origin \draw[green] plot [red, domain=-2:4, samples=200] (\x, {exp(-abs(\x)^2)}); \begin{axis}[ xtick=\empty, ytick=\empty, hide axis, xmin=-2, xmax=4, axis equal, width=6cm, height=7cm, anchor=south west, at={(-2cm,-2cm)}, ] \addplot [red, domain=-2:5, samples=200] (\x, {exp(-abs(\x)^2)}); \end{axis} \end{tikzpicture} \end{document}

So the same as in code "aaaa", "bbbb" and "dddd" should stick to lists, but "cccc" should be in different paragraph then lists (at least visually). The closest I got is by also adding \leavevmode at the begining: \newenvironment{nospitemize}{% \leavevmode% \begin{itemize}[topsep=-\parskip]% }{ \end{itemize}% \leavevmode% } but that creates too large space between "cccc" and next itemize

I have large latex document which not able to compile to html due to limitation of DVI. One such example: (/mnt/g/public_html/my_notes/solving_ODE/current_version/OUTPUT/12223_Monday_Ma rch_31_2025_04_39_20_AM_3788059/header.tex) (./body.4ct) --- file bodysubsubsection40249.htm --- l.1405711 --- TeX4ht warning --- \Link{tailbodysubsubsection40249.htm}? --- [65531 ! ==> Fatal error occurred: total_pages>=65536, bad output DVI file produced!

I was looking at using \includeonly by compiling each chapter one by one. This will limit the size of the DVI to only each chapter at time. I would need to edit index.tex by hand and change \includeonly until I finish all chapters. Here is MWE \documentclass{book} \ifdefined\HCode \includeonly{1} \fi \begin{document} \title{my title} \author{me} \date{\today} \maketitle % \tableofcontents \include{1} \include{2} \end{document} And 1.tex is \chapter{A} \section{A 1} some text And 2.tex is \chapter{B} \section{B 1} and some text Compiled using make4ht -ulm default -a debug index.tex "mathjax,htm,0" Now I edited index.tex again and changed \includeonly{1} to \includeonly{2} and saved the file. (made sure not to delete index.aux during this process). Then did make4ht -ulm default -a debug index.tex "mathjax,htm,0" But when I look at index.htm it only shows chapter 2. Chapter 1 is lost. I never used \includeonly before since not needed in PDF for me, as no problem compiling large pdf file. Is it possible to use this method to compile each chapter on its own to avoid the DVI limit and still get the final HTML page showing all chapters on it or is this not possible with tex4ht? TL 2026

In the MWE below, the TikZ picture is a ‘roadmap’ showing how various lemmas combine in a proof (vastly simplified from my original), and I would like to have the hyperlinked \refs to the lemmas (which are spread over multiple pages in my original). But with alt={...}, VeraPDF complains that Link annotations that target different locations shall be in separate Link or Reference structure elements If I remove alt={...}, the PDF passes validation. If I change \ref to \ref* to remove the hyperlinks, the PDF passes validation. If there is only one hyperlink in the TikZ picture, the PDF passes validation. The same problem occurs replacing on alt={...} with artifact. I understand that tagging is in development, but is there any quick fix or workaround that allows multiple hyperlinks in a TikZ picture with alt text? (Or is there perhaps some fundamental incompatibility with tagging multiple hyperlinks inside a TikZ picture?) MWE: \DocumentMetadata{ pdfversion=2.0, pdfstandard=UA-2, lang=en-GB, tagging=on, } \documentclass{article} \usepackage{unicode-math} \usepackage{hyperref} \usepackage{tikz} \newtheorem{lemma}{Lemma} \title{Test} \begin{document} Roadmap of proving the theorem: \begin{tikzpicture}[alt={Roadmap}] \node (A) at (0,0) {$A$}; \node (B) at (2,0) {$B$}; \node (C) at (4,0) {$C$}; \draw[->] (A) edge node[auto] {Lem.~\ref{lem:ab}} (B); \draw[->] (B) edge node[auto] {Lem.~\ref{lem:bc}} (C); \end{tikzpicture} \begin{lemma} \label{lem:ab} If $A$, then $B$. \end{lemma} \begin{lemma} \label{lem:bc} If $B$, then $C$. \end{lemma} \end{document}

I'm using the physics package and noticed an inconsistent behavior of its automatic delimiter feature. According to the package documentation, automatic bracing is extended to functions such as \exp, \log, \ln, \det, and \Pr. However, I found that parentheses and square brackets behave differently. Here is a minimal example: \documentclass{article} \usepackage{physics} \begin{document} \[ \exp[\frac{1}{x}] \] \[ \log[\frac{1}{x}] \] \[ \ln[\frac{1}{x}] \] \[ \det[\frac{1}{x}] \] \[ \Pr[\frac{1}{x}] \] \[ \exp(\frac{1}{x}) \] \[ \log(\frac{1}{x}) \] \[ \ln(\frac{1}{x}) \] \[ \det(\frac{1}{x}) \] \[ \Pr(\frac{1}{x}) \] \end{document} However, with the shorthand syntax, I observe the following behavior: \exp[...] → square brackets are automatically resized. \det[...] → square brackets are automatically resized. \Pr[...] → square brackets are automatically resized. \log[...] → square brackets are not resized. \ln[...] → square brackets are not resized. On the other hand, parentheses work correctly for all five functions: \exp(\frac{1}{x}) \log(\frac{1}{x}) \ln(\frac{1}{x}) \det(\frac{1}{x}) \Pr(\frac{1}{x}) all produce automatically sized parentheses. The physics manual only shows examples with parentheses, so I'm not sure whether the behavior for square brackets is intended. Also, if I use \ln\qty[\frac{1}{x}] and \log\qty[\frac{1}{x}], it can produce automatically sized parentheses. Question: Is this an intentional design choice, or is it a bug/inconsistency in physics? If intentional, why do \exp, \det, and \Pr accept automatic square brackets while \log and \ln do not?

I am experiencing a unexpected interaction between the New Computer Modern fonts and the bullets used for itemize environments. They are replaced by squared bullets and I didn't see any reference about it the documentation.

How can I draw a water molecule using tikz like the ones in the image below with "H" in hydrogen atoms and "O" in oxygen atom?

I've got a bunch of figures which are PGFPlots elements side by side, as such: \begin{figure}[ht]% \centering% \begin{subfigure}{.49\textwidth}% \centering% \sizedplot{../path/to/plot-dir/bunny-multires}{p1-rmse.tikz}% \end{subfigure}\hfill% \begin{subfigure}{.49\textwidth}% \centering% \sizedplot{../path/to/plot-dir/bunny-multires}{p1-times-graph.tikz}% \end{subfigure}\\[1pt]% % Note: the `bunny-multires-plot` key is defined as the "legend name" in p1-rmse.tikz: \pgfplotslegendfromname{bunny-multires-plot}% \caption{Blah, blah, blah.}% \label{fig/bunny-multires}% \end{figure}% Where the \sizedplot command is defined as such: \NewDocumentCommand{\sizedplot}{s O{\textwidth} m m}{% \bgroup% \def\basepath{#3}% \def\fullpath{\basepath/#4}% \mmznext{meaning to salt={\fullpath}}% \begin{memoize}% \IfBooleanTF{#1}% If star, do not resize to #2. {\begin{tikzpicture}\input{\fullpath}\end{tikzpicture}}% {\resizebox{#2}{!}{\begin{tikzpicture}\input{\fullpath}\end{tikzpicture}}}% \end{memoize}% \egroup% }% This indirection is mainly due to the fact I include data from CSV files relative to the path of the plots, like: \addplot table [options] {\basepath/losses.csv}. When doing this, and enabling external compilation through the use of the memoize package, both graphs (the subfigure elements) are detected as the same "source", leading to one of the graphs (often the second one in the order they were defined) being copied in both sub-figures after memoization + recompilation. What could go wrong here? I've added -- as shown above -- the full path as a source for the salt in memoize's options, hoping they would thus get detected as two different graphs, but nothing seems to make that specific use case work. If I only have one TikZ / PGFPlots image in a figure environment, it compiles just fine.

Instead, it only receives this bit of code to generate the hash: Code: \IfBooleanTF {\BooleanFalse }{\begin {tikzpicture}\input {\fullpath }\end {tikzpicture}}{\resizebox {\textwidth }{!}{\begin {tikzpicture}\input {\fullpath }\end {tikzpicture}}} And since it is the same for both pictures, this means the second graph (encountered later) will be saved under the "common" hash when compiling for the first time, leading to the graphs being the same on the final PDF... Now that I've discovered the cause, I need to dig deeper into why it happens 🙂

While using ce in the body, the - signs for the charge looks smaller. However, while using it in a math environment, the minus sign gets elongated and becomes more pronounced, which looks completely different than the previous one. I am using New CM, with lualatex. Is there a bypass for that? \ce{B-} \(\ce{B-}\), \ce{B+} \(\ce{B+}\), \ce{B^{2-}} \(\ce{B^{2-}}\), \ce{B^{2+}} \(\ce{B^{2+}}\)

I have a problem with the formatting of index entries. If an index entry has multiple page references and the list of page numbers wraps onto a new line, the continuation line starts flush left. Instead, I would like the continued page numbers to be either aligned under the first page number (i.e. in the middle) or right-aligned. In some cases, even the first line does not place the page numbers flush with the right margin (unfortunately, I am not able to reproduce it here). For example, I currently get: De Civitate Dei, 1 3 whereas I would like sth. like De Civitate Dei, 1 3 This is my ist-file: quote '+' headings_flag 0 heading_prefix "" heading_suffix "}\\nopagebreak\n" symhead_positive "Symbole" numhead_positive "" delim_0 "\\nobreak\\hfill " delim_1 "\\nobreak\\hfill " delim_2 "\\nobreak\\hfill " delim_n "\\nobreak, " suffix_2p "f." preamble "\\begin{theindex}\n\n" postamble "\n\n\\end{theindex}\n" item_0 "\n\n \\indexspace\n\n \\item " item_1 "\n \\indexspace\n \\subitem " item_2 "\n \\indexspace\n \\subsubitem " What I want is: a continuation indent for wrapped page-number lines. So the page numbers stay in a fixed “column”, and if they wrap, the second line is indented under that column, not flush left, like here: This is my MWE: \documentclass{scrbook} \usepackage{imakeidx} \usepackage{hyperref} \usepackage{showframe} \makeatletter \renewcommand{\@idxitem}{\par}% remove \hangindent40\p@ \makeatother \makeindex \makeatletter \patchcmd{\idx@@heading}{\section*}{\chapter*}{}{} \makeatother \makeatletter %\renewcommand\@idxitem{\par} \renewcommand\@idxitem{\par\vspace{13pt}} \renewcommand\subitem{\par} \renewcommand\subsubitem{\par} \makeatother \begin{document} \section{First section} Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Is it possible to set the font style of the node labels in tikz-cd? Pay attention: the node labels, not the arrow labels or the node itself. I tried with every label/.append style={font=\scriptstyle,}, but it doesn't work.

We packaged a font so it can be reusable in different documents (see below). Is it the right way to do it? Comments welcome. The package is then used by simply adding \usepackage{ourfont}. We tried to look at various font packages but it seems to vary much between implementations... In a document (so without modifying the package), we want to disable ligatures for non-italic, or maybe just disable the Discretionary ones, tbd. Again, what is the right way to do this? This font (legally) comes from Adobe and is split into several .otf files for weight/style/optical sizes, hence the complexity of the loading... This is first way we do this, and fontspec seems to offer many solutions. All comments welcome. Thanks. \NeedsTeXFormat{LaTeX2e} \ProvidesPackage{ourfont}[2026-06-28] \RequirePackage{fontspec} \setmainfont{OurFont}[ NFSSFamily = OurFont, Numbers = {OldStyle,Proportional}, Ligatures = {Common,Discretionary}, UprightFeatures = { Font = *, SizeFeatures = { {Size = -8.9, Font = *-Capt}, {Size = 9.0-14.9, Font = *}, {Size = 15.0-22.9, Font = *-Subh}, {Size = 23.0-, Font = *-Disp}, }, }, ItalicFeatures = { Font = *-It, SizeFeatures = { {Size = -8.9, Font = *-ItCapt}, {Size = 9.0-14.9, Font = *-It}, {Size = 15.0-22.9, Font = *-ItSubh}, {Size = 23.0-, Font = *-ItDisp}, }, }, BoldFeatures = { Font = *-Bd, SizeFeatures = { {Size = -8.9, Font = *-BdCapt}, {Size = 9.0-14.9, Font = *-Bd}, {Size = 15.0-22.9, Font = *-BdSubh}, {Size = 23.0-, Font = *-BdDisp}, }, }, BoldItalicFeatures = { Font = *-BdIt, SizeFeatures = { {Size = -8.9, Font = *-BdItCapt}, {Size = 9.0-14.9, Font = *-BdIt}, {Size = 15.0-22.9, Font = *-BdItSubh}, {Size = 23.0-, Font = *-BdItDisp}, }, }, FontFace = {l}{n}{ Font = *-LtDisp, }, FontFace = {l}{it}{ Font = *-LtItDisp, }, FontFace = {sb}{n}{ Font = *-Smbd, SizeFeatures = { {Size = -8.9, Font = *-SmbdCapt}, {Size = 9.0-14.9, Font = *-Smbd}, {Size = 15.0-22.9, Font = *-SmbdSubh}, {Size = 23.0-, Font = *-SmbdDisp}, }, }, FontFace = {sb}{it}{ Font = *-SmbdIt, SizeFeatures = { {Size = -8.9, Font = *-SmbdItCapt}, {Size = 9.0-14.9, Font = *-SmbdIt}, {Size = 15.0-22.9, Font = *-SmbdItSubh}, {Size = 23.0-, Font = *-SmbdItDisp}, }, }, ]

I am trying to draw a line in TikZ between two arbitrary points, for example, from $A(0,0)$ to $B(3,5)$, where the gradient (degradation) runs perpendicularly (transversely) to the path itself. The line should be solid black in the exact center and fade smoothly to white/transparent on both the top and bottom edges, looking like a soft or blurred brush stroke. like this: I managed to approximate this by drawing a manual path with calc offsets and calculating the specific shading angle manually: \begin{tikzpicture} % Define coordinates for the horizontal path (center-line) % A is the starting point, B is the ending point \coordinate (A) at (0,0); \coordinate (B) at (6,0); % Create a vertical degradation (fading) using a shaded rectangle. % We define a rectangle centered on the line, where: % - top color fades to white % - bottom color fades to white % - middle color is solid black % Adjust the height (e.g., 0.6cm) to make the bar and blur thicker or thinner. % Adjust the width (the X coordinate of B) to make it longer or shorter. \shade[top color=white, bottom color=white, middle color=black, line cap=butt] ($(A) + (0, 0.3cm)$) rectangle ($(B) + (0, -0.3cm)$); \end{tikzpicture}

I'm trying to work two parallel columns of text with the multicol package. When I try to break columns it seems to be ignored. Here's a MWE: \documentclass[b6paper, 10pt, twoside, openright, final]{memoir} \setlrmarginsandblock{1.5cm}{.5cm}{*} \setulmarginsandblock{1.5cm}{*}{1} \checkandfixthelayout{} \usepackage{multicol} \usepackage{xcolor} \usepackage{lipsum} \title{ My Memoir } \author{M} \date{June 28, 2026} \begin{document} \begin{multicols}{2} \parbox[t]{\columnwidth}{% \lipsum[1][1-2] } \vfill\ \columnbreak \parbox[t]{\columnwidth}{% \lipsum[2][1-2] } \vfill\ \end{multicols} \end{document} The text continues on the same paragraph without switching columns. How can I make sure the text switches from the left column into the right column?

I want to adjust the table of contents such that The names of \parts are centered in the toc and appear with page numbers and The name of the toc has two lines that are centered.

A user asked how to stack diacritics on small capitals in NewCM. Small capitals are accessible via scmp from lowercase and via c2sc from uppercase, but stacking fails. For example, when A is followed by U+0304 (combining macron) with c2sc enabled, the letter switches to the plain capital A. When U+0304 is removed, the small capital A is produced correctly. NewCM contains information for stacking diacritics on its small capitals as well, but it seems there is a bug in the engine, or something else is happening that I do not understand. Here is an MWE: \documentclass{article} \usepackage[default]{fontsetup} \begin{document} \addfontfeatures{RawFeature=+c2sc} \textsc{ā, ī, ū, ṭ, ḍ, ḷ, ṁ, ṃ, ṇ, ṅ, ñ} \textsc{a}̄ \textsc{a} A Ā \end{document} Notice that small-cap n with tilde works because this character is precomposed in the font, but we cannot expect the font to have all characters precomposed, which is why we need stacking. The output is erratic. The line \textsc{a}̄ does not result from stacking but from the negative width of the macron, which is why it is not centered. Note that you may find another font that produces correct output, but this will only be because it has the above characters precomposed. Stacking still fails. We cannot precompose everything.

I'm trying to draw straight lines in a matrix using nicematrix, and I achived the code: \documentclass{article} \usepackage{nicematrix,tikz} \begin{document} \begin{equation*} \begin{bNiceMatrix} \CodeBefore[create-cell-nodes] \begin{tikzpicture} %\draw[blue,-] (3-1) -- (4-2) ; %\draw[blue,-] (4-2) -- (3-4) ; \draw[blue,-] (3-1.north west) -- (4-2.south east) ; \draw[blue,-] (4-2.south east) -- (3-4.north east) ; \end{tikzpicture} \Body a_{11} & a_{12} & a_{13} & a_{14} \\ a_{21} & a_{22} & a_{23} & a_{24} \\ a_{31} & a_{32} & a_{33} & a_{34} \\ a_{41} & a_{42} & a_{43} & a_{44} \end{bNiceMatrix} \end{equation*} \end{document} My problem is the straight lines are not centered in the entries of the matrix (see image below); I considered also \draw[blue,-] (3-1) -- (4-2) ; \draw[blue,-] (4-2) -- (3-4) ; instead of \draw[blue,-] (3-1.north west) -- (4-2.south east) ; \draw[blue,-] (4-2.south east) -- (3-4.north east) ; but in this case the two line are not linked. Any hint (desirably keeping the matrix created by nicematrix)? Thanks.

I'm trying to do the following in LuaLaTeX: having the main font be Arial; having the upper case letters in math font be Arial (if posible, not a strong requierement); having the lower case letters in math font be latin modern; having the numbers in math font be in Arial. To achieve these goals, I found out that the package mathastext could be a solution (as mentionned in a previous post), if used with the option "noletters". However, this option doesn't work as intended (or maybe I didn't understand what it was meant to do).

I have just started using the 3d library in TikZ (and I'm quite new to the tikz package itself). I am modelling a physics problem; I want to draw a sphere that represents my system. The particularity of that sphere is to have regions delimited by parallel circles around the North and South poles; I would like to color these regions in a different shade than the rest of the sphere. I have been looking everywhere and I can't find how to do this (if it is possible); using \path and \fill doesn't seem to work. Sorry if it's a stupid question, thanks for your help!
