I have this example of table, the main language of document is arabic (RTL script), I changed the language before the table to English to solve the problem of Arabic text not appearing in cells with a colored background in RTL context Text disappears in tabularray with bg color (polyglossia). The problem is that the caption appears in LTR direction with english tablename, so what I need is to apply the command \selectlanguage{english} after caption creation so that the caption still in RTL context. \documentclass{article} \usepackage{xcolor} \usepackage{tabularray} \usepackage{polyglossia} \setmainlanguage{arabic} \setotherlanguage{english} \newfontfamily\arabicfont[Script=Arabic]{Amiri} \begin{document} \begin{center} \selectlanguage{english} \begin{longtblr}{ colspec = {|X[c,m,1.6]|X[c,m,1.4]|X[c,m,1.4]|}, hlines, vlines, cells={cmd=\textarabic}, row{1} = {bg=blue!20, rowsep=5pt,font=\bfseries}, rowsep=8pt } يسار & وسط & يـمين\\ Left & Center & Right \\ \end{longtblr} \end{center} \end{document}

XCharter-Math provides lowercase script letters e,g,o in the range U+2100 to U+2140, they can be accessed by their Unicode name but not as \symscr{e} etc. For other fonts, f.i. NewComputerModern the commands \symscr{e}… work as expected. \symscr{e} also works with XCharter-Math when used with lua-unicode-math. Test file to be compiled with LuaLaTeX: \documentclass{article} \newcount\test \test=0 % 0, 1 or 2 \ifcase\test % This fails: \symscr{} prints italic instead of cursive \usepackage{unicode-math} \setmathfont{XCharter-Math.otf} \or % This works as expected: \usepackage{unicode-math} \setmathfont{NewCMMath-Book.otf} \or % This works as expected too with lua-unicode-math : \usepackage{lum-xcharter} \fi \begin{document} %\showoutput \(\mscre \mscrg \mscro, \symscr{ego}, \symscr{EGO}\)\quad \ifcase\test xcharter \or NCM \or lum-xcharter\fi \end{document} And the outputs: I guess there is something wrong with my font XCharter-Math, hints to fix this bug would be greatly appreciated.

Under macOS, after updating TeXLive packages that, among other things updated biber to the August 14, 2026, version, the biber binary will not run. How fix?

I'm trying to write out some formulas from my Aerospace textbook but when I use \oiiint (with \usepackage{esint}) I get an undefined control sequence. Here are the Tex expressions that I'm having trouble with: \documentclass{article} \usepackage{amssymb} \usepackage{mathtools} \usepackage{amsthm} \usepackage{esint} \begin{document} \[ \oiint_{S} \vec{A} \cdot \mathrm{d}\vec{S} = \oiiint _{\mathcal{V}}\left( \nabla \cdot \vec{A} \right) \mathrm{d}\mathcal{V} \] \[ \frac{\partial}{\partial t}\oiiint _{\mathcal{V}}\rho \,\mathrm{d}\mathcal{V} + \oiint _{S}\rho\vec{V}\cdot \mathrm{d}\vec{S} = 0 \] \end{document} This is what is rendered as well: Here are the Raw Logs: !

I am submitting a revised version of a paper to a journal. The editor has asked for a track changes file. I used latex-diff (Tom-Hejda's solution) in Overleaf, however it doesnt give the desired output with reference list and in-text citations. My files also have a lot of packages in the preamble because of the equations/tables etc that I have used. How can I generate a clean file with references? My Overleaf file: https://www.overleaf.com/read/dyhgkdkzkgcg#b6a2c2

I would like to write a snippet in VS Code LaTeX to obtain comment boxes, according to the following examples Test %%%%%%%%%%%% % % % Test % % % %%%%%%%%%%%% A second Test with several lines respecting indentation %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % % A second Test % % with several lines % % respecting indentation % % % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% I have to confess that a more general snippet, adapted to any mode, would be the best solution, so for Text mode, it would be +----------+ | | | Test | | | +----------+ and for C mode, it would be /*********** * * * Test * * * ***********/ However, since I ask this question on tex.stackexchange, I would be happy with a solution for the LaTeX mode only.

I am trying to achieve the following look for my chronos timeline: This is the "date centric" style and I have tried to define a new colour scheme like so: \documentclass[a4paper,12pt]{article} \usepackage[dvipsnames,svgnames]{xcolor} \usepackage{chronos} \chronosnewcolourscheme{newcols}{% event/above={Rhodamine,Cerulean}, event/below={Cerulean,Rhodamine}, } \begin{document} \begin{figure} \centering \begin{chronos} [ date centric, colour scheme=newcols, timeline={ dates=1974:1990, }, ] \chronosevent {date={1978}, as is, yshift=5pt, special date={1978}, name=A, name content=Theory A, } \chronosevent {date={1984}, as is, name=B, name content=Theory B, yshift=30pt, } \end{chronos} \end{figure} \end{document} With this code, the colours of the event lines/text stay unchanged, so I understand that I need to make adjustments to the "date centric" style too, but what exactly needs to be changed?

I need to draw a cornered bracket over several lines in a table. I want it to look somewhat like this: You can see the bracket on the right. I also have a table with three columns, just like in the picture. The first columns are the line numbers, the second latin text, the third are abbreviations about the lines' metre. I have all this working just fine except for the bracket. I first tried to get help from AI and this is the result: \documentclass{article} \usepackage{tikz} \usetikzlibrary{tikzmark} \newcounter{verstabsystem} \NewDocumentCommand{\startsystem}{}{% \stepcounter{verstabsystem}% \xdef\verstabSysCurrent{\theverstabsystem}% \makebox[0pt][l]{\strut\tikzmark{verstabSysStart\verstabSysCurrent}}% } \NewDocumentCommand{\endsystem}{}{% \makebox[0pt][l]{\strut\tikzmark{verstabSysEnd\verstabSysCurrent}}% \begin{tikzpicture}[remember picture, overlay] \draw[thick] ([xshift=-0.3em]pic cs:verstabSysStart\verstabSysCurrent) -- ++(-0.3em,0) -- ([xshift=-0.3em]pic cs:verstabSysEnd\verstabSysCurrent) -- ++(0.3em,0); \end{tikzpicture}% } \begin{document} \begin{table} \begin{tabular}{rcl} 1 & text & \startsystem \\ 2 & text & an sy\textsuperscript{10} \\ 3 & text & \\ 4 & text & \endsystem \\ 5 & text & \\ 6 & text & \\ \end{tabular} \end{table} \end{document} Which produces: As you can see, the bracket is there, but there are a few issues with it that I have been unable to solve: It has the shape of an opening bracket [, but I need a closing one ]. The vertical line is not vertical. I first thought that the verticalness issue was due to there being text in the same line, but that happens even when there is none. I believe that the solution would be to move the horizontal line to the right so it is at the same height as the bottom one and then connect the right ends of both lines with a vertical one. How may this be achieved? Thanks in advance!!

This is a follow-up question of https://tex.stackexchange.com/a/163355. After numerous experiments with the lettrine package in the task of preparing a collection of poems for a friend who is unfamiliar with LaTeX, I have found the superb piece of code from Steven B. Segletes, and was delighted primarily because only the \startverse command does the job. However when long verses exceed the settings as in the example below, there is a space created between the lines 2 and 3 of the poem. I have been able to eliminate the problem by removing the "verse" package from the preamble, and also to some extent by changing the length of the minipage, in the code \begin{minipage}{4in}. But I wish to better understand the role of the {4in} minipage lenghth. (I wonder if a size depending on the textwidth would be more adequate and why the verse package affects the results. \documentclass[12pt, a5paper,draft]{book} \usepackage{scalerel} \usepackage[english]{babel} \usepackage[numberpoems, clearpageafterpoem]{poetrytex} \usepackage{showframe} \usepackage{stackengine} \usepackage{verse} %Following code borrowed from Steven B.

I'm trying to define some custom theorem environments with tcolorbox, while keeping the usual amsth syntax \begin{my_env}[My Optional Title] \label{my_optional_label} stuff \end{my_env} instead of tcolorboxs \begin{my_tcb_env}{My Optional Title}{my_optional_label} stuff \end{my_tcb_env} one.

I achieved a good-looking result with the following definitions: \definecolor{definitioncolor}{HTML}{0072B2} % Blue \definecolor{theoremcolor}{HTML}{D55E00} % Vermillion \definecolor{examplecolor}{HTML}{F0E442} % Yellow \definecolor{propositioncolor}{HTML}{D55E00} % Vermillion \definecolor{corollarycolor}{HTML}{D55E00} % Vermillion \definecolor{lemmacolor}{HTML}{D55E00} % Vermillion \definecolor{constructioncolor}{HTML}{CC79A7} % Reddish Purple \tcbset{ breakable, commonbox/.style={ boxrule=0.3pt, left=10pt, right=10pt, top=8pt, bottom=8pt, arc=3pt, outer arc=3pt, %colback=white, colbacktitle=white, coltitle=black, colframe=black!12, % Very subtle border enhanced, }, } % Theorem \NewTColorBox[auto counter, number within=section]{thm}{+O{}}{% commonbox, title={\textbf{Theorem} \thetcbcounter\IfBlankTF{#1}{}{ --- #1}}, colframe=theoremcolor, colback=theoremcolor!10, } % Definition \NewTColorBox[use counter from=thm]{dfn}{+O{}}{% commonbox, title={\textbf{Definition} \thetcbcounter\IfBlankTF{#1}{}{ --- #1}}, colframe=definitioncolor, colback=definitioncolor!10, } % Definition \NewTColorBox[use counter from=thm]{construction}{+O{}}{% commonbox, title={\textbf{Construction} \thetcbcounter\IfBlankTF{#1}{}{ --- #1}}, colframe=constructioncolor, colback=constructioncolor!10, } and so on. The problem now is that whenever I \begin{dfn}[My definition] \label{my_definition} stuff \end{dfn} and then try to \ref{my_definition}, I end up with the section number, not the definition number. The same goes for the other environments. This is in some sense expected, but I don't know how to change my code to make it work properly.

I have a rather long LaTeX document. I compile it with XeLaTeX. It additionally contains knitr chunks. Some of the R code that is executed during this process takes a very long time to run because it's doing things like fitting a bunch of multinomial models and making API calls to Open Street Maps and the General Social Survey. Sometimes, I just want to compile the pure LaTeX portions of the document to make sure I didn't format something wrong or just to be able to read a paragraph that I just edited in PDF format instead of in plain text. In other words, I don't want to wait for the knitr chunks to run just to see how a modified table looks or to read a few paragraphs. The only way I know of to do this is to comment out every knitr chunk in the document. I can easily comment out just the very first chunk that runs my R scripts in the first place, but then the document breaks and can't be compiled due to all the knitr chunks and in-line knitr stuff. Alternatively, I could comment out all these later portions of code, too, but this is a book-length document, so that would be exceedingly tedious, more tedious than just waiting for the R scripts to all run. Is there an option or something built into the knitr package that would allow me to compile the LaTeX document but skip literally every knitr portion of the document? For example, say I have the following very small document: \documentclass{article} \title{Some title} \author{Some person} \date{Some date} \begin{document} <<run_script>>= source("stats_stuff.R") @ Here is some text. This number, \Sexpr{calculated_num}, comes from an object generated by my R script. <<plot>>= plot_from_R @ Now I am done with this document. \end{document} And say I have this in stats_stuff.R: calculated_num <- 5 + 7 plot_from_R <- boxplot(sample(1:20, 5)) My goal is to be able to do something simple like add an argument to run_script so bypass the knitr stuff in the document. Is that possible?

I have this MWE: \documentclass{article} \usepackage{amsmath} \newcommand{\AnschauungMultiline}[2]{% \left\langle\hspace{-1.8mm}\left\langle \vphantom{\begin{matrix} A \\ A \end{matrix}} #1 \mathrel{:} #2 \right\rangle\hspace{-1.8mm}\right\rangle } \begin{document} \[ \AnschauungMultiline{x}{ \begin{aligned} \forall y\biggl( g(&0)\in y \wedge H(0)\in y \wedge \forall n \Bigl((g(n)\in y\to g(n+1)\in y)~\\[-1mm] &\wedge (H(n)\in y\to H(n+1)\in y)\Bigr) \to x\in y\biggr) \end{aligned}} \] \end{document} How may I obtain outer double angle delimiters whose tops align with the top of the upper written line $g(0)\in y\wedge H(0)\in y \ldots$, and whose bottoms align with the bottom of the lower written line $\wedge (H(n)\in y\to H\ldots$? It would be very useful if the solution allows regulation for fine adjustment.

Im curious to know if there is a more efficient way to have triangles repeat themselves in one another without needing to run the \draw command for each line of the triangle; similar to Sierpinski's triangles is essentially what it is but in a different way for nesting. So far i've been doing the \draw command as such \documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} [scale = 3] \draw[thick] (0,0) -- (2,0) -- (1,1.73205) -- cycle; \draw[thick] (0,0) -- (1,0.8) (2,0) -- (1,0.8) -- (1,1.73205) -- (1,0.8); \draw[thick] (1,0.8) -- (1.566667,0.769); \end{tikzpicture} \end{document} Ive provided an example above of what it should look like however I need to define what the colors mean and some rules it has. Meaning of Colors: Black = 1st Generation triangles, Blue = 2nd Generation triangles, and Red = 3rd Generation triangles as well each generation has a specific intersection where all the points meet ( for example black has a intersection in the middle where all points meet ) I should also say that each generation has its own "sub section" where the rule above applies to each sub section and these sub sections are divided by the lines of the previous generation. ( for example a 3rd generation sub section can have a different intersection than another 3rd generation sub section this is so each has one intersection which will for the sake of simplicity be set in the center for all generations) if you have any questions on this to better help me feel free to ask and I apologize if some of it seems confusing it is a rather "niche" section of discrete geometry relating to triangles and other two dimensional shapes ( side note i'd like this concept to be done with other two dimensional shapes as well so if theres a way to set the starting shape to say a circle or another shape that would be amazing; and it would follow the same rules I have revealed here).

If I create a minimal drawing using the standalone class, I get a warning: \documentclass[tikz]{standalone} \begin{document} \begin{tikzpicture} \draw circle (1); \end{tikzpicture} \end{document} $ pdflatex [filename] [blah blah] [1 Non-PDF special ignored! <special> papersize=57.30548pt,57.30548pt A similar warning is emitted when using LuaTeX instead of PDFTeX. This message can safely be ignored, of course, but if I recall correctly, it was not there in past versions, and I thought I'd ask if someone knows why it occurs and whether it should occur. I don't know when this started happening, but I also do not remember it happening prior to a particular TeXLIVE upgrade (which would have been from TeXLIVE 2022 -> 2025, iirc, which Fedora was waiting on for quite a while so they could reorganize the packages).

When attempting to plot pH-metric titration curves for weak/polyprotic acids and bases using piecewise Henderson-Hasselbalch approximations, sharp breaks and discontinuous artifacts often appear near equivalence points. Is there a robust, automated way in TikZ and pgfplots to plot continuous curves using exact charge and mass balance equations, while also supporting geometric constructions such as the tangent method (méthode des tangentes)?

Background: I transfer a document to LaTeX using class book. Its content doesn't change, so pages are "fixed", besides variations in vertical space I might introduce by accident using packages titleps and titlesec. Observations: Now the document has a handful of very long titles in \chapter{} and \section{}. Though this spoils the TOC after typesetting, that's not an issue here. My issue is: on some pages the text in the headers will be tooo long. However, I don't want to make them shorter manually, also to preserve the original way of expressing things from the author. Idea: Have long titles for \chapter{} and \section{} in body text AND have them truncated when typeset in the header. So if this is a long title working fine enough inside the document: \section{A very complex thing discussed for various aspects, like this one and that one} The header then should read, where appropriate A very complex thing disussed fo... (strict truncation) or A very complex thing disussed ... (more thoughtful truncation). So all I need to do is to pick the title (i.e. its token list or string) select a shorter range display said result best probably done via expl3 My problem It looks like there is an obstacle from package titleps itself. I can retrieve the whole text, but can't select a range from it. This might be an expansion-related problem, which I have not enough experience with. If I see it correctly, terms like \chaptertitle, \sectiontitle are automatically defined via the \csname approach: $ texdef -t latex -s -p titleps sectiontitle % titleps.sty, line 140: \let\sectiontitle\@empty % latex.ltx, line 158: \def\@empty{} From titleps.sty \let\parttitle\@empty \let\chaptertitle\@empty \let\sectiontitle\@empty \let\subsectiontitle\@empty \let\subsubsectiontitle\@empty \let\paragraphtitle\@empty \let\subparagraphtitle\@empty \newcommand\iftitle[1]{% \expandafter\ifx\csname #1title\endcsname\@empty \expandafter\@secondoftwo \else \expandafter\@firstoftwo \fi} MWE The idea is to delegate the truncation process to macro \shrt, which will later turn into a more useful truncation functionality, with proper case decisions. But for now it should just make text shorter, when asked to do so in \sectionhead. If there's a better approach, please let me know. \documentclass[10pt]{book} \usepackage[pagestyles,explicit]{titlesec} \usepackage[ % allowing a more concise screenshot later paperheight=12cm, paperwidth=16cm, left=25mm, right=20mm, top=15mm, headheight=10mm]{geometry} \usepackage{parskip} %\newcommand\shrt[1]{#1} % kind of quick default; comment out % THIS kind of works for body text, but not for \sectiontitle \ExplSyntaxOn % \tl_new:N \txt \newcommand\shrt[1]{% % mixed remains from several runs % \tl_set:Nn \txt #1% % assign #1 first? % \txt% %>\tl_range:nnn {\tl_use:N \txt}{1}{6}<} >\tl_range:nnn {#1}{1}{6}<% > < are just left/right indicators } \ExplSyntaxOff % ~~~ Just to get used to this package again ~~~~~~~~~ %\titleformat{\chapter}[display] %{\normalfont\huge\bfseries}{\chaptertitlename\ \thechapter} % Chapter 1 usw. %{20pt}{\Huge#1} %\titleformat % {\chapter} % cmd % [hang] % shape % {\bfseries\Large} % format % {\thechapter.} % label % {1em} % sep % {\shrt{#1}} % before code // chapter-title % []% after code \titleformat {\section} % cmd [hang] % shape {\bfseries} % format {\thesection.} % label {1em} % sep {#1} % before code // section-title [] % after code \newpagestyle{main}{ \sethead[\thepage][\chaptertitle][(\thesection] % even {\thesection)}{ \shrt{\sectiontitle% <<< idea: make it shorter, when too long }}{\thepage}} % odd \pagestyle{main} % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \begin{document} \chapter{Test for the chaptertitle} \section{What's up?} 1234567890 \shrt{1234567890} \newpage \section{What's up now?

While LaTeX has a similar mechanism for inputting single characters, it doesn't mention something like \symttit{ABC€} where you only need to switch ABC in \symttit, meaning you don't need to switch € in \symttit in Monospace Italic style. Replacing characters in the argument - even within other commands unicode-math font character new mapping in \symsf I also used the above reference programs to switch font characters in a similar way: \documentclass{article} \usepackage{unicode-math} \ExplSyntaxOn \NewDocumentCommand{\symttit}{m} { \group_begin: \cs_set:Npn A { \texttt{\textit{A}} } \cs_set:Npn B { \texttt{\textit{B}} } \cs_set:Npn C { \texttt{\textit{C}} } \symit{#1}% Make a unavailable \symttit glyphs in fallback fonts \group_end: } \ExplSyntaxOff \begin{document} \texttt{\textit{ABC}} vs $\symttit{ABC}$ \end{document} However, it does not support switching between Monospace Italic style by inputting a single character within \symttit. The full name of the LaTeX command is required to switch to other character types (like the previous mechanism of converting \symsf{\alpha} to Greek letters).

I'm using Latex with Zotero. I want to cite a book from a book series. The book has an author and an editor, and the book series has a separate title (the Dover Thrift Editions) and its own editor. When I add an Editor and a Series Editor role as in the MWEB below, I get the following in the bibliography: "Ed. by Janet B. Kopito, Red. by Susan L. Rattiner". The Red. (redacted) does not reflect the role of the series editor properly. Also, the name of the series is currently not part of the entry in the .bib file. How can I add the information for this publication such that it is displayed completely and accurately? MWEB: \begin{filecontents*}{\jobname.bib} @book{frost2019, title = {New {H}ampshire}, author = {Frost, Robert}, editor = {Kopito, Janet B.}, editora = {Rattiner, Susan L.}, editoratype = {redactor}, } \end{filecontents*} \documentclass{article} \usepackage[% autolang=other, backend=biber, style=numeric, defernumbers=true, autocite=superscript, giveninits=false, uniquename=false, language=english ]{biblatex} \addbibresource{\jobname.bib} \begin{document} \cite{frost2019} \printbibliography \end{document}

Currently I use this to make verbatim display with rounded frame and yellow background, which works well, but I have to use \begin{tcolorbox}[myBox] \begin{verbatim} ..... \end{verbatim} \end{tcolorbox} But I'd like to be shorten this and be able to just write \begin{myVerbatim} ..... \end{myVerbatim} I can't make normal latex environment using \newenvironment{myVerbatim}[1]{% \begin{tcolorbox}[myBox] \begin{verbatim} }{% \end{verbatim} \end{tcolorbox} } Because what I am passing is verbatim. So I tried to use fancyvrb and its \DefineVerbatimEnvironment{myVerbatim}{Verbatim}{ but I am not able to get the exact look I currently have using tcolorbox and verbatim. From what I found it seems fancyvrb does not support rounded corners for frame and also does not support background color. fillcolor is not same. I do not want to use listings package in any way in all of this. (causes issue with tex4ht) Below I show my current tcolorbox implementation and my fancyvrb one. The question is: Is it possible to obtain the same look but using \DefineVerbatimEnvironment ? \documentclass[12pt]{article} \usepackage{tcolorbox} \usepackage{xcolor} \usepackage{verbatim} \tcbuselibrary{breakable} \definecolor{bg}{RGB}{255,255,226} \tcbset{ myBox/.style={ colframe=gray, colback=bg, boxrule=0.5pt, boxsep=4pt, arc=4pt, left=0pt, right=0pt, top=0pt, bottom=0pt } } \begin{document} \begin{tcolorbox}[myBox] \begin{verbatim} some 3^2 verbatim % text \sin x def hello_world_and_my_var(): print("Underscores work fine inside standard verbatim!") return True \end{verbatim} \end{tcolorbox} %I'd like to just do the following instead %\begin{myVeratim} % ................ %\end{myVerbatim} \end{document} Compiled using lualatex Here is the best I can do using fancyvrb \documentclass[12pt]{article} \usepackage{fancyvrb} \usepackage{xcolor} \definecolor{bg}{RGB}{255,255,226} % Define the custom verbatim environment \DefineVerbatimEnvironment{myVerbatim}{Verbatim}{ frame=single, % Adds the outer border framerule=0.5pt, % Sets border thickness rulecolor=\color{gray}, % Sets border color fillcolor=\color{yellow}, % Sets the yellow background color framesep=4pt, % Adjusts internal padding (matches boxsep) } \begin{document} \begin{myVerbatim} some 3^2 verbatim % text \sin x def hello_world_and_my_var(): print("Underscores work fine inside standard verbatim!") return True \end{myVerbatim} \end{document} Gives Which is not exactly the same. The solution I am looking for is to generate similar output as the first one above, but using \begin{myVerbatim}....\end{myVerbatim} to reduce typing. But with restrictions no use or loading listing package no use of external temporary files Any solution that does this will be great. It does not have to use fancyvrb either For an example, solution such as \newtcblisting{myVerbatim}{ colback=yellow!20, % background color colframe=gray, % border color boxrule=0.5pt, % border thickness arc=4pt, % rounded-corner radius boxsep=4pt, % padding left=4pt, right=4pt, top=4pt, bottom=4pt, listing only } Will not work, as this causes listing package to be loaded.

I want to make an environment which takes two mandatory arguments, a title and a url, and prints a box, with the title at the top, a QR code of the url on the left, and the url itself at the bottom. The contents of the environment should be printed in the right of the box, wrapping under the qr code if long enough. I've got close. The MWE below creates a command which does this. But: It's not an environment. The tcolorbox tools available make it harder to create an environment with preset content. The qr code is printed, but leaves a thick margin at the top, between the QR code and the box. If the text is short, the QR code doesn't 'push' the bottom of the box down to accommodate it. (all demonstrated by the MWE below). The main issue seems to be floating (or otherwise managing) the QR code inside the box. I'm not sure how to approach this; below I used wrapfig2 because another question I found had success it. It compiles, but it doesn't quite work. How can I achieve what I want? \documentclass{article} \usepackage[skins]{tcolorbox} \usepackage{qrcode} \usepackage{wrapfig2} \usepackage{lipsum} % <title> <link> <description> \NewTotalTColorBox{\mweqrbox}{ m m m }{ enhanced,colback = white,colframe=black,coltitle=black, sharp corners,boxrule = 0.4pt, fonttitle = \itshape, attach boxed title to top text left = { yshift = -0.5\baselineskip-0.5pt, yshifttext = -0.25\baselineskip }, boxed title style={ tile, size = minimal, left = 0.5mm, right = 0.5mm, colback = white, before upper = \strut }, title={#1}, subtitle style = { fontupper = \scriptsize\ttfamily, colback = white, colframe = white, top=0pt, nobeforeafter }, lower separated=false }{% \begin{wrapfigure}{l} \qrcode{#2} \end{wrapfigure} #3 % Description % this is useful because otherwise, with a short description, the % subtitle cuts through the middle of the QR code. \tcblower \tcbsubtitle{#2} } \begin{document} \mweqrbox{Foo}{https://example.com/some/long/path#fragment}% { Some text here.

I am trying to create a tabularx table with centered content. Everything works as long as each cell is one column wide. But as long as I add multicolumn cells, the centering is skewed.

I am currently working on a new book and would like to store two different sets of endnotes at the end of the document. One Should go under the Title "Botanical Relevance" and one "Noteworthy Mentions". I have managed at least to set the titles, but I cannot wrap my mind around the formatting. The idea is to predefine two sets of endnotes (one \alph and one \ arabic) with manyfoot and store them in two separate endnote libraries at the end of the document. The endnote libraries should preferably be called with a command like "\theendnotesB" and "\theendnotesN". I tried using "\let\footnoteB=\endnote" and changing it to "\let\footnoteN=\endnote" after having called the first endnote library, but the attempt failed. Any help appreciated.

Maybe it is a matter of taste, but I think the space between integral sign and integrand is way too large when the kpfonts-otf package is in use: \documentclass{scrartcl} \usepackage{kpfonts-otf} %\usepackage{unicode-math} % loaded automatically by kpfonts-otf \removenolimits{\int} \removenolimits{\oint} \begin{document} \begin{equation} I = \int_0^x S ds \end{equation} \begin{equation} I = \oint_0^x S ds \end{equation} \end{document} This has already been discussed in this question, but I still think the space is not correct. [I am not sure, whether the tags are ok. Pls modify them if necessary.]

I am typesetting an Arabic document using XeLaTeX and the polyglossia package. I am trying to build a table using the tabularray package. The Problem: Whenever I apply a background color to a specific row using the bg key (e.g., row{1} = {bg=blue!20}), the Arabic text inside that row completely disappears in the output PDF. The text in the other rows (which do not have a background color) renders perfectly fine. It seems like a layering or grouping issue where the bidi package (loaded by polyglossia) conflicts with tabularray's drawing engine, causing the colored box to either cover the text or push the RTL text out of bounds. I have already tried: Removing font=\bfseries from the row settings. Using manual \textbf{} inside the cells. Wrapping the text in \mbox{}. Using \SetCell{bg=blue!20} instead of row{1}. None of these solved the issue; as long as the background color is present, the text vanishes. Minimum Working Example (MWE): \documentclass{article} \usepackage{xcolor} \usepackage{tabularray} % RTL Setup \usepackage{polyglossia} \setmainlanguage{arabic} \setmainfont{Amiri} % Standard Arabic font for testing \begin{document} \begin{center} \begin{longtblr}{ colspec = {|X[c,m,1.6]|X[c,m,1.4]|X[c,m,1.4]|}, hlines, vlines, row{1} = {bg=blue!20, rowsep=5pt}, % The text in this row disappears rowsep=8pt } \textbf{النهاية} & \textbf{التفسير الهندسي} & \textbf{التمثيل البياني} \\ Text appears here & Text appears here & Text appears here \\ \end{longtblr} \end{center} \end{document}
