Below is my MWE: \documentclass{article} \usepackage{hyperref} \newcommand{\nocontentsline}[3]{} \newcommand{\tocless}[2]{\bgroup% \let\addcontentsline=\nocontentsline#1{#2}% \egroup} \begin{document} \tableofcontents \newpage \section{test} \subsection{test1} \subsubsection{test2} \subsubsection{test3} \subsection{test4} \pdfbookmark[3]{test5}{mark1} \tocless\subsubsection{test5} \subsection{test6} \section{test7} \tocless\subsection{test8} \newpage a \end{document} The code above makes the toc without sections (and sub...sections) that have \tocless command before them. Thanks to \pdfbookmark subsubsection "test5" appears in pdf outline. I want to have it automatically bookmarked in \tocless, I think I would need to add a counter and the like (to increment "mark1"). However the most difficult part is [3] in \pdfbookmark, as it needs to be appropriate for command (subsection -> 2, subsubsection -> 3). I think my question boils down to: Can I - from command (subsection, subsubsection) - get correct number (2, 3). If not, is it possible at all to automate adding it to pdf outline without appearing in toc. In my use case documentclass is set to book, however I am interested in broader picture if possible.

Sorry if anything I ask or provide is inappropriate; I am new to TeX Stack Exchange. I am writing a Traditional Chinese LaTeX document. Sometimes I will need commentary in either align or equation, which is, of course, in Chinese. I usually use \text{} for the commentary, but they look cluttered and hard to read. However, removing the \text{} around the commentary simply makes the commentary disappear in the output. Is there a workaround? Re-defining \text{} won't help me, 'cause it'll still look cluttered. For reference I am on https://overleaf.com, using XeLaTeX. \documentclass{article} \usepackage{xeCJK} \setCJKmainfont{Noto Sans CJK TC} \usepackage{amsmath} \begin{document} This works: \begin{align} 1 + 1 &= 2 \text{ 一個人和一隻狗合起來是兩個東西}\\ 2 + 3 &= 5 \text{ 兩個人和三隻狗合起來是五個東西} \end{align} This doesn't: \begin{align} 1 + 1 &= 2 \quad 一個人和一隻狗合起來是兩個東西\\ 2 + 3 &= 5 \quad 兩個人和三隻狗合起來是五個東西 \end{align} \end{document} EDIT By "cluttered" I mean the code, not the output. Also, I would like to clarify that without \text{}, the commentary simply doesn't get displayed in the output at all, and I am looking for a way to de-clutter my code while getting the output to also work.

Earlier this year I reported what appears to be a regression in LuaLaTeX's \mathit behaviour that was introduced in TeX Live 2026. The original discussion with the LuaTeX developers is here: https://tug.org/pipermail/luatex/2026-April/008187.html In short, the commonly recommended practice of using \mathit{} for multi-letter identifiers produces visually displeasing results with LuaLaTeX v1.24.0 (TeX Live 2026): \documentclass{standalone} \begin{document} \begin{tabular}{ll} \verb!|\emph{different}|! & |\emph{different}| \\ \verb!|$\textit{different}$|! & |$\textit{different}$| \\ \verb!|$\mathit{different}$|! & |$\mathit{different}$| \\ \verb!|$different$|! & |$different$| \\ \end{tabular} \end{document} As far as I understand, the underlying issue has since been fixed in LuaTeX v1.25.8. However, TeX Live generally does not update the LuaTeX binary during the lifetime of a TeX Live release, so this fix is unlikely to reach most TeX Live 2026 users until the next annual release. Assuming a user is required to use LuaLaTeX (for other reasons), what is the recommended workaround in the meantime? I would prefer not to change all occurrences of \mathit in my sources for what appears to be a temporary regression, and downgrading to TeX Live 2025 also seems like an undesirable solution. Alternatively, is there a practical way to use a newer LuaTeX binary with an existing TeX Live 2026 installation? (I have tried to do so, but I have not managed to get it working.) Thanks!

I am trying to write a simple chemical reaction like this one: I have the MWE below. Can anyone help, please? \documentclass{article} \usepackage{chemfig} \begin{document} Nuclear reaction: \[ \schemestart \chemfig{^{235}U} \arrow{->} \chemfig{^{231}Th} \+ ^4\alpha \schemestop \] \end{document} with the error: !

Ok. Hear me out. I had this problem in the earlier versions of TeXLive, but was never able to fully understand where it is coming from, and what exactly is the solution. The only workaround was to perform a clean install of TeXLive. I am on Windows 11 64bit, TeXLive 2026. I tend to update my TeXLive occasionally to catch up with the possible updates on the packages that I am interested. Just couple of days ago, I checked the updates again using tlshell.exe (TLShell TeX Live Manager), and the update list that is shown in the following picture came up. A typical update of packages in TeXLive is not like this. Note that all the updateble packages have the version number of 79618. Also note that there is an update of "tlmgr" My first question is: What kind of update is this? Is this some sort of a major update of the TeXLive system for the purpose of some sort of a clean-up, instead of individual package updates? I have updated "tlmgr" first, and updated all the packages. But then, I have this problem of "Back end gone. Last command: info --data name,remoterev,rcat-version, category,shortdesc" Then the tlshell.exe quits on me... I have tried many many things to get rid of this error, but did not work, so just out of curiosity, I uninstalled TeXLive and did a clean installation. To my surprise, the error still occurs. So, this is telling me that the TeXLive update that was recently rolled-out has an issue. Am I right? I had this issue last year and could not solve it back then. So I am really wondering what exactly this problem is about. If anybody can direct me to a page with an explanation and a possible solution, that would be also fine. Also, what is the suggested action here when we see this sort of update list? Should we just wait for TUG to fix the problem for a couple of days, without performing an update? Or is this related to my own TeXLive setup?

(This is a follow-up of How to ignore space in sorting order of biblatex + biber?.) At least in French, spaces should be ignored in sorting order of strings.

I would like to have a tikzcd within tikzpicture. The reason for this is I want to have a standard commutative diagram from tikzcd, but then also put lines, text, and shapes in the "background" of the diagram using tikzpicture treating the diagram as static and without interacting with the diagram at all (allowing for overlap, for example). A solution for tikzpicture within tikzpicture is using \newsavebox, but this doesn't work for tikzcd within tikzpicture. Specifically, \UseRawInputEncoding \documentclass[11pt]{article} \renewcommand{\baselinestretch}{1.05} \usepackage{tikz-cd} \begin{document} \newsavebox{\mybox} \sbox{\mybox}{ \begin{tikzpicture} \end{tikzpicture} } \end{document} compiles, but \UseRawInputEncoding \documentclass[11pt]{article} \renewcommand{\baselinestretch}{1.05} \usepackage{tikz-cd} \begin{document} \newsavebox{\mybox} \sbox{\mybox}{ \begin{tikzcd} A \arrow[r] & B \end{tikzcd} } \end{document} does not compile and throws the following error. Moreover, \UseRawInputEncoding \documentclass[11pt]{article} \renewcommand{\baselinestretch}{1.05} \usepackage{tikz-cd} \begin{document} \newsavebox{\mybox} \sbox{\mybox}{ \begin{tikzpicture} \begin{tikzcd} A \arrow[r] & B \end{tikzcd} \end{tikzpicture} } \end{document} does not compile and throws the following error. How can I have a tikzcd within tikzpicture?

Thanks to https://tex.stackexchange.com/a/764554/18401, I can easily have a (TikZ) node followed by a line, the total width of them being fixed (40mm below). In the following MCE, I use code from the link above (not optimizing in order to make it clearer) and: for the first case, I use: the east anchor, draw to the right, the west anchor of the node considered for the total width, and the result is as expected; for the second case, I want to exchange the node and the line (not mirroring them), so my code exchanges: east anchor → west anchor, draw to the right → draw to the left, west anchor → east anchor of the node considered for the total width. But, for the second case, there is slight shift (about 1pt) to the right I can't explain. How to get rid of it? \documentclass{article} \usepackage{tikz} \usepackage[showframe]{fgruler} \usepackage{geometry} \geometry{ paperwidth=60mm, paperheight=50mm, margin=1cm, marginparwidth=0mm, textwidth=40mm, } \newcommand{\test}[3]{% \noindent% \tikz \draw[line width=2pt] (0,0) node[line width=0pt,inner sep=0pt,draw, anchor=#1, ] (foo) {Foo} -- ([shift=(#2:40mm)]foo.#3);% } \begin{document} \test{east}{right}{west} \test{west}{left}{east} \end{document}

I use texlive 2025 and try to set a footnote into scrletter's signature. The following code seems to work, but isn't: The footnotemark/footnotetext-pair appears but the footnote's numbering is off by +1 and the implementation is ugly (due to the loose distribution of code: footnotemark and footnotetext) \documentclass{scrartcl} \usepackage{scrletter} \setkomavar{signature}{Alfred E. Neumann\footnotemark{}} %<- works, but ugly \begin{document} \begin{letter}{You} \opening{Dear You,} Hello World! \closing{Best regards,} \footnotetext{MAD} %<- uhhh, that's really ugly! 😉 \end{letter} \end{document} Thus I tried to get rid of the distribution of code, using this: \documentclass{scrartcl} \usepackage{scrletter} \setkomavar{signature}{Alfred E. Neumann\footnote{MAD}} %<- preferred solution \begin{document} \begin{letter}{You} \opening{Dear You,} Hello World! \closing{Best regards,} \end{letter} \end{document} But I can't get it to work: only the footnote mark appears, but the footnotetext doesn't. The mark is off by +1, too. Could someone please help me and demonstrate how to solve this? Thanks!

I saw a cool optical illusion while surfing the web. It depicts objects which appear to move, but aren't, due to a repeating pattern within the static fill. I want to reproduce it in TikZ.

I'm trying to use a pic to produce diamonds of a fixed width and height (specified by a parameter) and of specified line and fill colors. My first attempt was based on code I copied and pasted from Google in response to the search "can tikzpicture pic macros have arguments." Google responded with what seemed to be just what I needed (under a heading of "Default Values and Keyword Arguments"). But I have not been able to get my tweak of it to work. (But having typed that last sentence, I've now tried the code verbatim as Google provided it, and I got a pgfkeys error. Sigh). In my attempts, I have gotten the default values to work: if I change the default values, then those changes are reflected in the output. But for some reason when I pass my pic key-value pairs, they seem to have no effect. Oh, and when (by way of debugging) I try commenting out the lines that set the defaults, I get error messages about the resulting "undefined control sequences." I've also looked at various answers here on SE and tried adjusting my code to resemble theirs. No such adjustments have made any difference. Nor, I'm sorry to say, has the PGF/TikZ manual been of any help. I'm confident that the problem is some fairly simple thing that I'm too bone-headed to find. So here's a MWE: \documentclass{article} \usepackage{tikz} \usetikzlibrary{shapes.geometric} \tikzset{ pics/mydiamond/.style={ code={ \node[ draw, diamond, color=\mydiamondcolor, fill=\mydiamondfill, minimum width=\mydiamondradius*2, minimum height=\mydiamondradius*2, align=center] (0,0) {}; } }, % Set defaults pics/mydiamond/.cd, color/.store in=\mydiamondcolor, color=purple, fill/.store in=\mydiamondfill, fill=yellow!30, radius/.store in=\mydiamondradius, radius=2mm, } \tikzset{blue thing/.style={color=blue,fill=blue!20}} \begin{document} These three diamonds should be of different sizes and colors, \begin{tikzpicture} \draw (0,0) pic {mydiamond}; \draw[radius=5cm, color=red, fill=green] (1,0) pic {mydiamond}; \draw (2,0) pic {mydiamond={radius=10cm, color=blue, fill=white}}; \end{tikzpicture} But they are not. Nor do such diamonds seem to pick up on .styles (\begin{tikzpicture} \draw (0,0) pic[blue thing] {mydiamond}; \end{tikzpicture}, see what I mean?), although things like garden-variety nodes and geometric shapes (\begin{tikzpicture} \draw[blue thing] (0,0) node {Blue Thing!}; \end{tikzpicture} and \begin{tikzpicture} \draw[blue thing, radius=2mm] (1.2,0) circle; \end{tikzpicture}) do. \end{document} The output I get from that MWE is As my MWE illustrates, among the variants I've tried is taking the key-value pairs out of the brackets appended to the \draw command and putting them into ={} appended to the pic name. But no dice.

I defined a function \__foo:w #1+#2+#3, like the MWE below \documentclass{article} \begin{document} \ExplSyntaxOn \cs_new:Npn \__foo:w #1 + #2 + #3 \q_stop { \textbf{#1},~ \textit{#2} \tl_if_blank:eF {#3} { ,~ \texttt{#3} } } \__foo:w tex + live + 2026 \q_stop % \__foo:w tex+live \q_stop \ExplSyntaxOff \end{document} But if users use \foo:w tex+live, due to the second delimiter + could not be founded, then error arises: File ended while scanning use of \foo:w <inserted text> Certainly, I know I can use l3seq, but I think it is not an elegant way. Is there a way to allow the usage \__foo:w tex+live \q_stop? Note \textbf, \textit, \texttt are just for demoing; in fact, I will use other personal defined functions.

Objectives: remove top left cell all contents are vertically and horizontally centered well balanced padding in each cell make it relatively much more beautiful \documentclass[12pt,border=12pt]{standalone} \usepackage{amsmath,array,tikz} \usetikzlibrary{math} \newcommand{\graph}[2][]{ \begin{tikzpicture}[baseline=(current bounding box.center)] \draw[blue,thick,->] (-1.5,#2)--(1.5,#2) node[right]{$x$}; \draw[red,thick,domain=-1.5:1.5,samples=100] plot(\x,{#1\x*\x/2}); \end{tikzpicture} } \renewcommand{\arraystretch}{1.8} \setlength{\tabcolsep}{18pt} \begin{document} \begin{tabular}{| >{\centering\arraybackslash}m{2.2cm}| >{\centering\arraybackslash}m{5.2cm}| >{\centering\arraybackslash}m{5.2cm}|} \cline{2-3} & $\mathbf{a>0}$ & $\mathbf{a<0}$ \\ \hline $\mathbf{D<0}$ & \graph{-1/2} & \graph[-]{1/2} \\ \hline $\mathbf{D=0}$ & \graph{0} & \graph[-]{0} \\ \hline $\mathbf{D>0}$ & \graph{1/2} & \graph[-]{-1/2} \\ \hline \end{tabular} \end{document} Any improvements are always welcome!

I found that "itemize" works inside "longtblr" when it is wrapped with a "minipage": \usepackage [ a4paper, left = 0.2cm, right = 0.2cm, top = 0.1cm, bottom = 0.2cm, ] {geometry} \usepackage{tabularray} \usepackage{lipsum} \newcommand{\rowgap}{10pt} \begin{document} \begin{center} \DefTblrTemplate{firsthead, middlehead,lasthead}{default}{} \begin{longtblr}[presep=-4pt,postsep=0pt] {colspec = {p{3.2cm}X},width=\textwidth,colsep=0pt,rowsep=0pt} 1 December 1871 & Some intro text:\\ & \lipsum[1-3] \\[\rowgap] 15 June 2016 & Some text:\\ & \begin{minipage}[t]{\linewidth} \begin{itemize} \item \lipsum[7] \item \lipsum[8] \item \lipsum[9] \end{itemize} \end{minipage} \\[\rowgap] 30 March 2051 & Other intro text:\\ & Hello man! \\[\rowgap] \end{longtblr} \end{center} \end{document} That code produces the following output: However, if one of the "itemize" entries is made longer, for example, \item \lipsum[7] \item \lipsum[8] \item \lipsum[9-11] the "minipage" prevents the "itemize" environment from breaking across pages. As a result, the entire list is moved to the second page instead of being split between the first and second pages, producing the following output: My question: inside a "longtblr", how can I split an "itemize" list — wrapped in a "minipage" — across pages? Should I wrap my "itemize" list in a different environment that allows it to split across pages? If so, which one? Are there any other solutions for using "itemize" inside "longtblr"? EDIT (9 July 2026): Thanks, everyone, for your comments! I realize I didn't explain why I chose to use a table here. My intention is to take advantage of some features that — to my understanding — are specific to the table environment. For example, the ability to highlight particular rows and columns by applying different colors: \documentclass[11pt,english]{article} \usepackage [ a4paper, left = 0.2cm, right = 0.2cm, top = 0.1cm, bottom = 0.2cm, ] {geometry} \usepackage{tabularray} \usepackage{lipsum} \newcommand{\rowgap}{10pt} \usepackage{xcolor} \definecolor{MyColor1}{rgb}{0.22,0.45,0.70} % light blue \definecolor{MyColor2}{rgb}{0.55,0.75,0.65} % mint green \begin{document} \begin{center} \DefTblrTemplate{firsthead, middlehead,lasthead}{default}{} \begin{longtblr}[presep=-4pt,postsep=0pt] {colspec = {p{3.2cm}X},width=\textwidth,colsep=0pt,rowsep=0pt} 1 December 1871 & Some intro text:\\ & \lipsum[1-3] \\[\rowgap] \SetRow{bg=MyColor1!20} 15 June 2016 & Some text:\\ & \begin{minipage}[t]{\linewidth} \begin{itemize} \item \lipsum[7] \item \lipsum[8] \item \lipsum[9] \end{itemize} \end{minipage} \\[\rowgap] \SetRow{bg=MyColor2!20} 30 March 2051 & Other intro text:\\ & Hello man! \\[\rowgap] \end{longtblr} \end{center} \end{document} Which gives this output: I was therefore wondering whether \begin{description} ... \end{description} can provide the same functionality. So far, I have not been able to find a way to reproduce this feature within the "description" environment.

I want to load luaotfload.sty with TeXInfo and here is my minimal code: \input texinfo @documentencoding UTF-8 @setfilename sample.info @settitle sample @include luaotfload.sty @bye If I use PDFTEX=luatex texi2pdf inn.texi, it produces the following: : Undefined control sequence. l.3 %% by Elie Roux <elie.roux@telecom -bretagne.eu> ? If I understand correctly, TeXInfo treats @ as a special character and turns the words following it into TeX control sequences, but the issue is that it should ignore TeX comments, which it is not. This could be a bug, but I thought I might have missed something very obvious.

I think in 2019 I built the following image with Adobe Illustrator for my book. Now, since there are so many images in pdf, I am slowly creating them in TikZ code. I wanted to know if there is something to create a trail for the blue particle similar to the main image or any other idea you have. Thank you. \documentclass{article} \usepackage{tikz} \usetikzlibrary{arrows.meta} \tikzset{rhtip/.tip={Triangle[line width=1pt, fill=white, length=9pt, width=9pt]}, pics/clock/.style args={#1/#2}{ code={ \def\dist{0.38} \draw[thin] (0,0) circle (\dist); \draw[line width=.7pt] (0,0) -- ({0.16*cos(90-30*#1-0.5*#2)}, {0.16*sin(90-30*#1-0.5*#2)}); \draw[line width=.7pt] (0,0) -- ({0.28*cos(90-6*#2)}, {0.28*sin(90-6*#2)}); } } } \begin{document} \begin{tikzpicture}[scale=.8] \draw[->] (0,0) -- (4.8,0) node[right] {$x$}; \draw[->] (0,0) -- (0,4.8) node[above] {$z$}; \draw[->] (0,0) -- (1.8,1.1) node[above] {$y$}; \node at (-0.4,4.3) {$\Sigma$}; \shade[ball color=cyan] (2.7,1.2) circle (0.2); \draw[brown!80!black,line width=2pt,-rhtip] (2.9,1.2)--(3.8,1.2) node[midway,above left] {$\mathbf{u}$}; \pic at (2.5,2.5) {clock={1/10}}; \node[blue!60!black] at (3.35,2.9) {$C(u)$}; \begin{scope}[shift={(5,1)}] \draw[->] (0,0)--(4.5,0) node[right] {$x'$}; \draw[->] (0,0)--(0,4.8) node[above] {$z'$}; \draw[->] (0,0)--(1.8,1.1) node[above] {$y'$}; \node at (-0.4,4.3) {$\Sigma'$}; \draw[magenta,line width=2pt,-rhtip] (0,3.6)--(1.8,3.6) node[midway,above] {$\mathbf{v}$}; \draw[green!60!black,line width=2pt,-rhtip] (2.1,1.3)--(3.7,1.3) node[midway,below] {$\mathbf{u}'$}; \pic at (2.5,2.5) {clock={2/20}}; \node[blue!60!black] at (3.55,2.9) {$C'(u')$}; \end{scope} \end{tikzpicture} \end{document}

I want to set the main text font to Arial using:\setmainfont{Arial} but I don't want the font used by \mathbf to be affected by Arial. I want \mathbf to keep the original default font. How can I achieve this? The following is my code: \documentclass{ctexart} \usepackage{amsmath,amssymb} \setmainfont{Arial} \begin{document} Hello world! with \verb|\setmainfont{Arial}| $\mathbf{N}_{+}$ \end{document} which gives: Noted that \mathbf also changed the N, which was not I was after, I want the Hello world! to be sans serif with Arial, while the \mathbf{N} gives the default bold N symbol with latinmodernmath.otf, the serif one as below:

I am trying to solve the same problem as the OP of this question, that is, set up some way to distinguish between equations and diagrams in a document and have it automatically be recognized by cleveref. The top answer there works beautifully... that is, as long as you don't load amsmath. If you do load it, then \cref will start referring to diagrams as equations again. For sake of self-containedness, here's an MWE based on that in the linked answer: \documentclass{article} \usepackage{tikz} \usetikzlibrary{cd} %\usepackage{amsmath} \usepackage{hyperref} \usepackage[noabbrev]{cleveref} \newcounter{diagram} \newenvironment{diagram}[1][]{% \begin{equation}% \begin{tikzcd}[#1]% \setcounter{diagram}{\value{equation}}% \addtocounter{diagram}{-1}% \refstepcounter{diagram}% }{% \end{tikzcd}% \end{equation}% } \crefname{diagram}{diagram}{diagrams} \creflabelformat{diagram}{(#2#1#3)} \begin{document} \begin{diagram}\label{diag:a} A \ar[r] & B \end{diagram} The above is \cref{diag:a}. \end{document} This produces the diagram together with "The above is diagram (1).", as desired. If you uncomment line 5, it instead produces the diagram with "The above is equation (1)." I'd be grateful for a solution with a similar use pattern that works in the presence of amsmath. In particular, I'd like to avoid the triple nesting \begin{diagram} \begin{equation} \begin{tikzcd} % ... \end{tikzcd} \end{equation} \end{diagram} that is common to the other answers at the linked question, if possible.

I'm trying to display three logos for the first slide of a presentation, that have various sizes and dimensions. I'm trying to align them vertically, but I do not manage to set the option of my tblr environment right. I found a silimar question on this forum, but the solution proposed (vertically center the last column only) is not working in my case. The example of this previous topic works well, but when I try to use it with my images, the other cells are no longer vertically centered but aligned at the bottom... Here is a MWE, I my beamer I use \includegraphics instead of the TikZ macros here, but the results is the same. \documentclass{article} \usepackage{tikz} \usepackage{tabularray} \newcommand{\logoA}{\tikz \draw [fill=red!50] (0,0) rectangle (2,1);} \newcommand{\logoB}{\tikz \draw [fill=blue!50!yellow] (0,0) rectangle (3,1);} \newcommand{\logoC}{\tikz \draw [fill=green!50] (0,0) circle (1.2cm);} \begin{document} \begin{tblr}{colspec = {Q[c,m]Q[c,m]Q[c,m]}} \hline \logoA & \logoB & \logoC \\ \hline % hline only for visualize the border of the table \end{tblr} \end{document}

I noticed that the \lastpagenumber is always one higher than the actual amount of pages (for example, showing 2 in a one page PDF instead of 1). It does not depend on the number of pages, I have seen this in one, two and three page PDFs. This is my MWE: \setuppagenumbering[location=,] \starttext Current: \pagenumber \\ Last: \lastpagenumber \stoptext This also applies to \totalnumberofpages, \lastpage. My version is 2026.02.19 11:49. Thanks in advance!

What is the command to use in mtpro2 (here the v. lite https://ctan.org/pkg/mtp2lite) the heavy bold \mathsf{F}? Actually I not remembering this.
