A MWE is probably better than lengthy explanations: \documentclass[tikz,10pt]{standalone} \usetikzlibrary{positioning} % savedbox with a sketch \newsavebox{\sdbox} \sbox{\sdbox}{% \begin{tikzpicture}[scale=0.35] \node (rbox) [fill=red] at (1,0) {}; \node (bbox) [fill=blue] at (1,1) {}; \end{tikzpicture}% } \begin{document} \begin{tikzpicture}[scale=0.5,font=\small] % blocks \node (comp) {computer}; \node[right = 1cm of comp] (sb) {\usebox{\sdbox}}; % arrow \draw[->] (rbox) -- (comp); \end{tikzpicture} \end{document} Upon compilation, you'll notice that the arrow does not link the node (rbox) from its absolute position after the node (sb) is drawn, as it should go from the red rectangle to the computer box. Would it be possible to achieve that goal?

How do I directly input foreign scripts into LuaLaTeX equations? I'm using LuaLaTeX with the unicode-math package. I have text mode setup that uses fallback font for any glyphs not covered. I also want to do the same for math mode, but with different font choices. I'm currently unable to input a foreign script like Kanji and Thai without adding commands like \text{} around it, despite having fonts that support Kanji and Thai. I want to be able to input scripts like Kanji and Thai into equations without extra commands as long as I have the proper font for it. \documentclass{article} \usepackage{unicode-math} \directlua{ luaotfload.add_fallback ("textFallback", { "SimSun:mode=harf;", } ) } \setmainfont{Arial}[RawFeature={fallback=textFallback}] \setmathfont{Latin Modern Math} \begin{document} This is a sample text. この文章は日本語です。 $∀天∈ℝ, ∀ค∈ℝ, 天+ค∈ℝ$ \end{document} Edit: Added clarification and included the Thai script.

I'm a physics teacher and I'd like to share here my way to write "dynamical" exercises. After posting a couple of questions more or less related, I've read comments implying that my way of doing could be improved. When I say "dynamical" I mean that the variables of my problem (\mass, \speed, ...) are coded in the questions. I don't wanna hard-code for the following reasons: If I write everything with, say, m=3kg, and then I wanna change to m=2kg, I don't wanna rewrite everything. I can reuse the questions very fast with different values, e.g. for exams or for the students to practise. Below a MWE of a "typical" problem. Please, do not focus on the Physics, but on the LaTeX ideas, mainly: Could I improve the way I store variables and compute other quantities? For the units, which command should I use: mathrm; text ; textup; ... ? Anything else? I want to make clear that, even if in this example I use basic maths (mainly the 4 operations), I typically need all the usual fonctions (powers, log, sqrt, exp, trigo), so any solution that you suggest should handle all these functions. \documentclass{article} \usepackage{xfp} % provides \fpeval \usepackage{amsmath} \begin{document} \def\mass{3} \def\speed{10} \def\distance{1} \edef\Ekin{\fpeval{0.5*\mass*\speed^2}} \edef\force{\fpeval{0.5*\mass*\speed^2/\distance}} A mass $m=\mass\, \mathrm{kg}$ starts moving from rest.

I have customized a MyReport.cls file with a custom optional parameter "Reference", which functions as follows: It defaults to None.

I want to change the arrow style of NPN when I use circuiTikz. I read the manual of CircuiTikz. All I found is that: I can only change the arrow position in 4.15.5.2 \ctikzset{transistors/arrow pos=end} It do change the position of arrow. Then, I tried to change the arrow style. I tried the following ways: \draw (7, 0) node[npn, scale=2.0, flow arrow/.style={->, >=Stealth}] (T) {}; \ctikzset{bipoles/npn/arrow/.style={>=Stealth}} None works! Could you kindly give me a solution? Thanks!

With TeX Live 2024 cleveref can compress cross-references including subequations parent numbers, like so: \documentclass{article} \usepackage{amsmath} \usepackage{cleveref} \begin{document} \begin{subequations}\label{eqn:one} \begin{align} a\label{eqn:onea}\\ b\label{eqn:oneb} \end{align} \end{subequations} \begin{align} c\label{eqn:two}\\ d\label{eqn:three} \end{align} \cref{eqn:one,eqn:two,eqn:three} \end{document} The \cref command gives as desired eqs. (1) to (3) However, with TeX Live 2025 and 2026, the compression does not occur and I get eqs. (1), (2) and (3) Is there a way to obtain the compressed output with TeX Live 2025 and 2026, without explicitly requiring a range (e.g., with \crefrange)? (This question is similar to this one, but the answer seems to indicate that I shouldn't get the compressed output with TeX Live 2024, which I do.)

Consider this MWE \documentclass[12pt]{article} \usepackage{amsmath} \usepackage{autobreak} \begin{document} \begin{align*} \begin{autobreak} A= (x + a + b +c+d+e+f+g) +y +z +(x + a + b +c+d+e+f+g) +e +d \end{autobreak} \end{align*} \end{document} Compile with lualatex gives I do not know how to make the output something like this (*), i.e. shift second and the rest of the lines more to the left. Using \MoveEqLeft from mathtools made it worst \documentclass[12pt]{article} \usepackage{amsmath} \usepackage{autobreak} \usepackage{mathtools} %\MoveEqLeft \begin{document} \begin{align*} \MoveEqLeft \begin{autobreak} A= (x + a + b +c+d+e+f+g) +y +z +(x + a + b +c+d+e+f+g) +e +d \end{autobreak} \end{align*} \end{document} Without modifying the lines themselves inside the autobreak manually by rewriting them, is it possible to obtain the desired output shown above in (*) by adding something in preamble or some other option for autobreak? Lualatex, TL 2026

A minimal working sample is as follows. \documentclass{article} \usepackage{amsmath} \usepackage[colorlinks=true]{hyperref} %\makeatletter %\def\tagform@#1{\maketag@@@{(\ignorespaces#1\unskip\@@italiccorr)}} %\DeclareRobustCommand{\eqref}[1]{\textup{\tagform@{\ref{#1}}}} %\makeatother \begin{document} \begin{equation}\label{eq} 1+2=3 \end{equation} TEXT \eqref{eq} TEXT \end{document} As you see, when using \eqref on the equation number, it produce only colorful equation number but black parenthesis, and also it produce a hyperlink only on equation number but including no parenthesis. Then how to make the parenthesis around equation number be colorful and hyperlinked too when using \eqref? I hope, the color could change when I reset linkcolor in hyperref. is it possible to redefine some setting to make the equation number be around with parenthesis when using \ref? In this case I think the parenthesis must be colorful and hyperlinked too.

The following MWE compile correctly, but if luacolor is uncommented the triangle is black instead of red. % !TEX TS-program = lualatex \documentclass{article} \usepackage{memoize} %\usepackage{luacolor} \usepackage{tikz} \begin{document} \begin{tikzpicture} \fill[red] (0,0)--(1,1)--(2,0)--cycle; \end{tikzpicture} \end{document} Is there a workaround? Or is this a bug in memoize and/or luacolor? (luacoloris needed for kerning reasons, that do not show in the above MWE.)

I'm trying to modify the theorem environment in ltx-talk so that it visually resembles the theorem environment in beamer. I was able to do so using talkthemetcolorbox. However, my attempt breaks the uncover overlay specification in a way that I don't quite understand. (MWE example below) \DocumentMetadata{tagging = on} \documentclass[aspect-ratio=4:3]{ltx-talk} \usepackage{talkthemetcolorbox} %Create a custom tcolorbox style for theorems \newtcolorbox{mythmbox}[1]{ title=#1, boxrule=0pt, enhanced, } \newtheorem{theorem}{Theorem} \RenewDocumentEnvironment{theorem}{D<>{all} +m}{ \begin{uncoverenv}<#1> \begin{mythmbox}{Theorem (#2)} }{ \end{mythmbox} \end{uncoverenv} } \begin{document} \begin{frame} Text \pause \begin{theorem}<3->{Pythagoras} The square of the hypotenuse is equal to the sum of the squares of the other two sides: \[ a^2 + b^2 = c^2 \] \end{theorem} Text \end{frame} \end{document} The code above changes the theorem environment visually as I desire, but it doesn't have the intended uncover behavior. (e.g. I see the theorem on all three slides). However, the code does have the right visual theorem environment and respects the overlay if I replace uncoverenv with onlyenv. (e.g. I see the theorem only on slide 3, but the spacing on slide 2 is not what I desire). It also has the right uncover behavior, but the wrong visual theorem environment if I replace D<>{all} +m with d<>{all} +m. (e.g. I see the theorem only on slide 3 , and the spacing on slide 2 is right, but there is no tcolorbox).

I'm trying to learn how to set up tagging for a document with a custom structure. For example, consider a document containing a quotation from the Bible. This has built in structure with things like chapters, verses, (potentially headings), different layouts, and maybe a reference at the end. At a minimum, I need to use the new block code to set up the blocks. But I'm guessing I also need to tag other elements like chapters and verses. But there's still minimal examples out there of how to do all this. If I want to to support tagging in my scripture package, I need to make good design decisions up front. And I don't really know what I'm doing. Here's a MWE example showing a basic structure for a quote from the Bible along with my best guesses relating to tagging.

For my use case I think it makes sense to have headings and paragraphs as the main structural elements rather than chapters and verses since modern Bibles can place chapter breaks within paragraphs and verses can split across paragraphs.

What I want to replicate is something as below: My very first (failed) attempt is as below: \documentclass[tikz,border=5pt]{standalone} \definecolor{myyellow}{RGB}{224,239,158} \definecolor{myteal}{RGB}{47,89,85} \begin{document} \begin{tikzpicture}[ cover/.style={line width=3pt,myyellow,fill=myteal}, myrect/.pic={\draw[cover] (0,0) rectangle (3,3) --cycle;} ] \foreach \i in {0,45,...,315} {\pic[rotate=\i] {myrect};} % \foreach \i in {0,10,...,350} {\pic[rotate=\i] {myrect};} \end{tikzpicture} \end{document} The last layer's order should be at the behind of the first one, which is not easy to be handle within the forloop \pic. Here below is my workaround: \documentclass[tikz,border=5pt]{standalone} \definecolor{myyellow}{RGB}{224,239,158} \definecolor{myteal}{RGB}{47,89,85} \begin{document} \tikzset{cover/.style={line width=3pt,myyellow,fill=myteal},myrect/.pic={\draw[cover] (0,0) |- (3,3) --++(0,-\fpeval{3*(2-sqrt(2))}) --(45:3)--cycle;}} \begin{tikzpicture} \pic{myrect}; \end{tikzpicture} \begin{tikzpicture} \foreach \i in {0,45,...,315} {\pic[rotate=\i] {myrect};} % \foreach \i in {0,10,...,350} {\pic[rotate=\i] {myrect};} \end{tikzpicture} \end{document} However, if I want to extend the angle step: \foreach \i in {0,10,...,350} {\pic[rotate=\i] {myrect};} that is not quite easy to get the code: \draw[cover] (0,0) |- (3,3) --++(0,-\fpeval{3*(2-sqrt(2))}) --(45:3)--cycle; exactly, the ++(0,-\fpeval{3*(2-sqrt(2))}) here. Any suggestions to solve the layer order issues?

This math is auto-generated by CAS. When using stix2 font, with lualatex, the letters on two rows of array are almost touching each others, making it little hard to read. Here is MWE. \documentclass[12pt]{article} \usepackage{amsmath} \usepackage{unicode-math} \setmainfont{STIX Two Text} \setmathfont{STIX Two Math} \begin{document} Since $n\neq -2$ then the solution of the reduced Riccati ode is given by \begin{align*} w & =\sqrt{x}\left\{ \begin{array}[c]{cc} c_{1}\operatorname{BesselJ}\left( \frac{1}{2k},\frac{1}{k}\sqrt{ab} x^{k}\right) +c_{2}\operatorname{BesselY}\left( \frac{1}{2k},\frac{1}% {k}\sqrt{ab}x^{k}\right) & ab>0\\ c_{1}\operatorname{BesselI}\left( \frac{1}{2k},\frac{1}{k}\sqrt{-ab}% x^{k}\right) +c_{2}\operatorname{BesselK}\left( \frac{1}{2k},\frac{1}% {k}\sqrt{-ab}x^{k}\right) & ab<0 \end{array} \right. \tag{1}\\ y & =-\frac{1}{b}\frac{w^{\prime}}{w}\nonumber\\ k &=1+\frac{n}{2}\nonumber \end{align*} \end{document} lualatex gives Notice how the bottom of 1/2k in first line is almost touching the letters on the second line. This is not the case with other fonts I tried: Removing the 3 lines so it now uses default CM font \usepackage{unicode-math} \setmainfont{STIX Two Text} \setmathfont{STIX Two Math} and compiling again, this is the result And replacing the 3 lines with this to try mlmodern \usepackage[T1]{fontenc} \usepackage{mlmodern} \DeclareSymbolFont{largesymbols}{OMX}{cmex}{m}{n} This is the result I can't change the code itself. But why stix2 lines seem to be too close to each others making it little hard to read. Is this just the nature of the stix2 font? Is there something one can add to preamble to help with this?

In this example I'm using the same table, but in reality the number of rows may vary. The tables used in \input are produced automatically and as read-only, so the longtable cannot be replaced by another environment, nor the 'preamble' edited (the code producing the tables may be, in any case). The point is that I need both table and subsection to pass to the next page if they don't fit in the current page, that's why I used \vspace*{\fill}. Is there another way of doing this? Does \vspace interfere with longtable? As I said, the code producing the tables may be edited (not my code, BTW), so a solution involving tinkering with the table code is possible, except for the constraint of using longtable, which is a must. Apart from a solution (i.e. removing those lines) I'd like to understand why this happens. I know longtable is supposed to break tables along pages, but I don't understand why the 'preamble' produces the above pictures. EDIT: Just to be absolutely clear as to what I'm aiming for, this is what the document looks like if I remove the longtable preamble: I do need tables and subsection titles to go to the next page if they don't fit in the current one. (/EDIT) Thanks!

Lualatex, TeXlive 2026, Linux. Compiling via command line. Technical question. MWE: \documentclass{article} %% Compile with lualatex. \usepackage{fontspec} \setmainfont{LibertinusSerif} %% Or any OpenType font. \begin{document} Hello, World. \end{document} Even though \fontspec requires packages xparse and luaotfload, I do not see those files included in either the Terminal output, or the log file. But obviously they are used. The same with fontenc if using only OpenType with UTF-8. In fact, I can comment-out the associated \RequirePackage lines in the various fontspec files, and all is good. I recall reading that xparse has been in the l3kernel (or related files) for several years. I can see why fontenc is not needed for the situation here. My question: Is it the case that luaotfload is now in the l3kernel when lualatex is the compiler? How I discovered this: Using my own custom document class, I experimented (cargo cult) with code that invoked luaotfload, but forget to \RequirePackage{luaotfload}. Nevertheless, my code worked, just as if I had loaded the package.

Hello, I want to understand the spacing after a minipage. As you can see in the image, after a minipage, it doesn't behave like two normal paragraphs. Please help me understand What does that space (marked '??' in the image) consist of? Is there anyway to make it automatically behave like two normal paragraphs or I can only fix it manually by adding \vspace? Thank you! Here is the MWE: \documentclass[12pt, a4paper]{article} \usepackage[ top = 1.6cm, bottom = 1.6cm, left = 1.8cm, right = 1.8cm ]{geometry} \setlength{\parskip}{10pt} \setlength{\parindent}{0pt} \linespread{1.2} \usepackage{enumitem} \setlist[enumerate, 1]{ label=\textit{\alph*.}, parsep=0pt, topsep=0pt, partopsep=0pt, itemsep=10pt } \begin{document} This is a plain text whose sole purpose is for the reader and composer of this document to see how the lines of text are spaced and to test the various spacing parameters that LaTeX offers. This text needs to be a little bit longer so I am currently typing nonsense.

Since I found \ddot{A} and \dddot{A}, can I create \rring{A} or \rrring{A}, that is, a double ring, and a triple ring like Å but with two or three extra dots? There seems to be a usage like this: How to denote the fifth derivative in Newton’s notation?, However, I tried a similar usage(by adding \scriptscriptstyle), but many error messages popped up. \documentclass{article} \usepackage{amsmath} \makeatletter \long\def\rring#1{% {\mathop {#1}\limits ^{\vbox to-1.4\ex@ {\kern -\tw@ \ex@ \hbox {\normalfont {\scriptscriptstyle \circ\!\circ}}\vss }}}% } \long\def\rrring#1{% {\mathop {#1}\limits ^{\vbox to-1.4\ex@ {\kern -\tw@ \ex@ \hbox {\normalfont {\scriptscriptstyle \circ\!\circ\!\circ}}\vss }}}% } \makeatletter \begin{document} $\rring{A}\rrring{a}$ \end{document} The error message is as below: ! Missing $ inserted. <inserted text> $ l.19 $\rring{A} \rrring{a}$ ?

When using the longtblr environment to typeset a table over multiple pages, the table is horizontally centred on the page. How can I have the table aligned flush with the left margin of the page? Minimum working example: \documentclass{article} \usepackage{tabularray} \begin{document} \begin{longtblr}[entry=none,label=none]{colspec={ll}} A & B \\ C & D \end{longtblr} \end{document}

Just wondering what is happening between fboxs on separate paragraphs, which prevents them from lining up as follows: \documentclass{article} \setlength{\parskip}{0pt} \setlength{\fboxsep}{0pt} \begin{document} \fbox{\strut Line One} \vspace*{-\baselineskip} \fbox{\strut Line Two} \end{document}

In my document, tabularray is my main table engine, but I also have a few macros that use classic tabular with \arrayrulecolor (from colortbl) for colored rules. The problem is that loading colortbl breaks any tblr environment containing pmatrix cells, with amsmath loaded. Minimal example \documentclass{article} \usepackage{amsmath} \usepackage{colortbl} \usepackage{tabularray} \begin{document} % This breaks as soon as colortbl is loaded: \begin{tblr}{hlines,vlines,colspec={ccc}} $\begin{pmatrix}a\\b\end{pmatrix}$ & $\begin{pmatrix}c\\d\end{pmatrix}$ & $\begin{pmatrix}e\\f\end{pmatrix}$ \\ \end{tblr} % This works fine (no nested array environment): \begin{tblr}{hlines,vlines,colspec={ccc}} $u_n$ & $v_n$ & $w_n$ \\ \end{tblr} % This also works fine (native tabular): \arrayrulecolor{red} \begin{tabular}{ccc} \hline $\begin{pmatrix}a\\b\end{pmatrix}$ & $\begin{pmatrix}c\\d\end{pmatrix}$ & $\begin{pmatrix}e\\f\end{pmatrix}$ \\ \hline \end{tabular} \end{document} Error ! Missing number, treated as zero. <to be read again> > l.XX \end{tblr} My file list *File List* article.cls 2025/01/22 v1.4n Standard LaTeX document class size10.clo 2025/01/22 v1.4n Standard LaTeX file (size option) colortbl.sty 2026/05/01 v1.0l Color table columns (DPC) array.sty 2026/02/24 v2.7b Tabular extension package (FMi) color.sty 2026-05-17 v1.3f Standard LaTeX Color (DPC) color.cfg 2016/01/02 v1.6 sample color configuration luatex.def 2025/09/29 v1.2f Graphics/color driver for luatex mathcolor.ltx tabularray.sty 2025-11-27 v2025C Typeset tabulars and arrays with LaTeX3 amsmath.sty 2026/05/19 v2.18d AMS math features amstext.sty 2024/11/17 v2.01 AMS text amsgen.sty 1999/11/30 v2.0 generic functions amsbsy.sty 1999/11/29 v1.2d Bold Symbols amsopn.sty 2022/04/08 v2.04 operator names l3backend-luatex.def 2026-02-18 L3 backend support: PDF output (LuaTeX) supp-pdf.mkii *********** What I've tried Swapping load order (tabularray before/after colortbl): no effect Loading colortbl via \usepackage[table]{xcolor}: no effect Use \UseTblrLibrary{amsmath} Notes The bug only affects tblr cells containing pmatrix (or presumably any amsmath array-based environment with \\ inside). I prefer keeping both engines: tabularray for complex tables, and tabular+colortbl for dynamically generated tables (loop-based content with \foreach etc., which tblr handles poorly). Posted here too: https://github.com/TeXackers/tabularray/issues/664 Is there a way to neutralize colortbl's patch selectively, or to protect pmatrix inside tblr cells?

I want to have a custom counter for examples, and then display it alongside with the value of the chapter counter where the example counter appears. Here is a MWE of what I currently have: \documentclass{amsbook} \begin{document} \newcounter{example} \chapter{One} \chapter{Two} \refstepcounter{example} \label{firstexample} \refstepcounter{example} \label{secondexample} Here are example \ref{firstexample} and example \ref{secondexample}. \end{document} The MWE above gives the output Here are example 1 and example 2. What I want instead is Here are example 2.1 and 2.2. What is the best/simplest ways to go about this? THANKS!
