The following is my MWE: \documentclass{article} \usepackage{mathtools} % Loads amsmath and defines \shortintertext % Logarithms \DeclareMathOperator{\lb}{lb} \NewCommandCopy{\oldlog}{\log} \newcommand*{\implicitbaselog}{% Uncomment only one of the following lines \oldlog % Uncomment to set ambiguous logarithm as default % \lb % Uncomment to set binary logarithm as default % \lg % Uncomment to set common logarithm as default % \ln % Uncomment to set natural logarithm as default } \newcommand*{\useambiguouslog}{\renewcommand*{\implicitbaselog}{\oldlog}} \newcommand*{\usebinarylog}{\renewcommand*{\implicitbaselog}{\lb}} \newcommand*{\usecommonlog}{\renewcommand*{\implicitbaselog}{\lg}} \newcommand*{\usenaturallog}{\renewcommand*{\implicitbaselog}{\ln}} \RenewDocumentCommand{\log}{e{_}}{ \IfNoValueTF{#1}{\implicitbaselog}{\oldlog_{#1}} } \begin{document} \begin{alignat*}{4} \shortintertext{With default definition of \texttt{\textbackslash implicitbaselog}: } \log x &= \oldlog x, && && && \\ \shortintertext{after \texttt{\textbackslash usebinarylog}: } \usebinarylog \log x &= \lb x \; &&\text{ and } && \; \log_3 x &&= \oldlog_3 x, \\ \shortintertext{after \texttt{\textbackslash usecommonlog}: } \usecommonlog \log x &= \lg x \; &&\text{ and } && \; \log_4 x &&= \oldlog_4 x, \\ \shortintertext{after \texttt{\textbackslash usenaturallog}: } \usenaturallog \log x &= \ln x \; &&\text{ and } && \; \log_5 x &&= \oldlog_5 x, \\ \shortintertext{after \texttt{\textbackslash useambiguouslog}: } \useambiguouslog \log x &= \oldlog x \; &&\text{ and } && \; \log_6 x &&= \oldlog_6 x. \end{alignat*} \end{document} Essentially, I would like to simply use \useambiguouslog, \usebinarylog, \usecommonlog, and \usenaturallog to change how \log is typeset in the document whenever it is not followed by a subscript indicating a specific base. Is there a way to improve my solution? Thank you in advance.

Using latexml (LaTeXML version 0.8.8) I am not able to compile an existing latex document which has listings inside tabular. I asked google AI but it does not know why. Here is MWE \documentclass[12pt]{article} \usepackage{latexml} \usepackage{listings} \lstdefinestyle{MMA}{% language=Mathematica,% basicstyle=\ttfamily\normalsize, } \begin{document} \begin{tabular}[c]{|p{3in}|p{3in}|}\hline \begin{lstlisting}[style=MMA] num = (s+1)(s+2); \end{lstlisting}% & \begin{lstlisting}[style=MMA] Clear["Global`*"]; ode=y'[x]==Sin[x] \end{lstlisting} \\\hline \end{tabular} \end{document} compiled with lualatex gives But with latexml >latexml --dest=A.xml A.tex latexml (LaTeXML version 0.8.8) processing A.tex Error:unexpected:\vtop Attempt to end mode text at A.tex; line 16 col 0 Error:unexpected:\vtop Attempt to end mode text at A.tex; line 22 col 0 Error:unexpected:\endgroup Attempt to close non-boxing group at A.tex; line 23 col 0 Warning:unexpected:\end{document} Attempt to end document with open groups, environments or conditionals at A.tex; line 25 col 0 Error:unexpected:<endgroup> Attempt to pop last locked stack frame at String; line 1 col 0 Error:malformed:ltx:listing <ltx:listing> isn't allowed in <ltx:p> at A.tex; line 15 col 0 Error:malformed:ltx:listing <ltx:listing> isn't allowed in <ltx:p> at A.tex; line 21 col 0 Conversion complete: 1 warning; 6 errors Is there a workaround for this? Why does latexml give this error on valid Latex code? Update Thanks to fix below. This is what I get now in HTML I just need now to figure how to remove those annoying little blue arrows

Consider the code: \documentclass{article} \usepackage{xcolor,graphicx} %\usepackage{transparent} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{figure} [!htb] \centering \includegraphics[width=8em,height=12em]{example-image} \end{figure} \begin{figure} [!htb] \centering \begin{tikzpicture} \node (a) at (0,0) {\includegraphics[width=8em,height=12em]{example-image}}; \filldraw[draw=red,fill opacity=.55,fill=green!65!black] (a.north west) rectangle (a.south east); \end{tikzpicture} \end{figure} \end{document} which produces Notice that in the second image there is a lighter shade of green between the outer red frame and in the inner black frame. QUESTION: How may I change the color of the region between the two frames from "lighter shade of green" to, say, red? I compile the code with xelatex. Thank you.

In the file where I load the packages for my book, I noticed that introducing \usepackage{mleftright} \mleftright changes the shape of the delimiters when I use mtpro2 Lite. I no longer remember why I added the \mleftright command. I also checked that, if I remove \mleftright but keep \usepackage{mleftright} nothing changes. Moreover, I expected the "new" curly braces to appear only when I use \ccases (the version with the braces that I prefer), while the standard cases environment should still use the default mtpro2 delimiters. However, in the last example I still get the new braces even though I am using cases rather than \ccases. Could you explain why this happens? \documentclass{book} \usepackage{mathtools} \usepackage{newtxtext} \usepackage[lite]{mtpro2} \usepackage{mleftright} \mleftright \begin{document} Il sistema associato ad $R$ è il seguente: \begin{equation}\label{rotassz} \ccases{\begin{aligned} x&=x'\cos \psi -y'\sin \psi \\ y&=x'\sin \psi +y'\cos \psi \\ z&=z' \end{aligned}} \end{equation} \begin{equation}\label{sisto1} \ccases{\begin{aligned} x_1&=a_{11}x'_1+a_{12}x'_2+a_{13}x'_3+a_{14}x'_4\\ x_2&=a_{21}x'_1+a_{22}x'_2+a_{23}x'_3+a_{24}x'_4\\ x_3&=a_{31}x'_1+a_{32}x'_2+a_{33}x'_3+a_{34}x'_4\\ x_4&=a_{41}x'_1+a_{42}x'_2+a_{43}x'_3+a_{44}x'_4 \end{aligned} } \end{equation} \[ \delta_{jk}= \begin{cases} 0 & \text{per $j\ne k$} \\ 1 & \text{per $j=k$} \end{cases} \] \end{document} Without \mleftright command:

I am learning context and found this problem below and looking for workaround.

Please write LaTeX code using pdflatex to reproduce "MODULO 2" with an approximate outline style similar to the image, sized to 12.4 cm wide and 5.3 cm high, without using TikZ.

Turning on LaTeX3’s experimental Tagged PDF support with the newpx fonts sometimes causes spacing between characters to be incorrect, especially when there are digits next to commas. Am I doing something wrong, or is there a workaround? The LaTex3 Project’s tagging status page lists newpx as compatible with tagging. The problem disappears if either tagging is turned off or if a different typeface (e.g. Computer Modern) is used. I am using TeXLive 2026 with pdftex.

I noticed that when I try to type unicode-math "⦦", the angle symbol is smaller than "∠" and "∟". Is there a way to draw another angle symbol that is outwardly slanted and the same size as "∠" and "∟"? \documentclass{article} \usepackage{unicode-math} \setmathfont{NewCMMath-Regular.otf} \begin{document} $∠∟⦦$ \end{document}

For certain tagged documents I need the following: Periods after numbers both in numbered headings and in ToC entries. Centered single-line chapter titles, no extraneous vertical space. No extraneous vertical space between chapters in List of Tables / Figures. The word “Part” / “Chapter” / “Appendix” in ToC lines for part and chapter. Up until the June 2026 release of LaTeX, I achieved the above by modifying bits copied from book.cls: \def\numberline#1{\hb@xt@\@tempdima{#1.\hfil}} %% Add period after numbers in ToC \def\@chapter[#1]#2{ ... 4 lines unchanged code ... \addcontentsline{toc}{chapter}{\@chapapp\space\thechapter.\hspace{1em}#1}% %% Custom ToC ... 7 lines unchanged code ... %%\addtocontents{lof}{\protect\addvspace{10\p@}}% %% No extra blank lines in LoF %%\addtocontents{lot}{\protect\addvspace{10\p@}}% %% No extra blank lines in LoT ... 6 lines unchanged code ... } \def\@makechapterhead#1{% %%\vspace*{50\p@}% %% Eliminate vertical space {\parindent \z@ \centering \normalfont %% Centered ... 2 lines unchanged code ... \huge\bfseries \@chapapp\space \thechapter. %% Add period after number %%\par\nobreak\vskip 20\p@ %% Eliminate newline and vertical space ... 4 lines unchanged code ... %%\vskip 40\p@ %% Eliminate vertical space }} %% Similarly modified versions of \@makeschapterhead, \@part, \@spart In the presence of \DocumentMetadata (the PDF needs to be tagged), the LaTeX June 2026 release uses the template mechanism for sectioning commands. The old fragile approach shown above no longer works. I can now achieve my first three goals by editing appropriate key-value pairs as in the following MWE: \DocumentMetadata{lang=en-us,tagging=on} \documentclass[oneside]{book} \makeatletter \def\numberline#1{\hb@xt@\@tempdima{#1.\hfil}} \EditInstance{heading}{chapter} { , after-penalty-vspace = 0pt , after-vspace = \baselineskip , prefix = \@chapapp , number-format = \thechapter. , heading-decls = \centering \parindent0pt \bfseries \Huge , contents-extra = } \EditInstance{heading}{part} { , number-format = \thepart. , heading-decls = \centering\bfseries\Huge } \DeclareInstanceCopy{headformat}{part}{std} \DeclareInstanceCopy{headformat}{chapter}{std} \makeatother \begin{document} \tableofcontents \mainmatter \part{My part} \chapter{My chapter} \section{My section} \appendix \chapter{My appendix} \end{document} Kudos to the developers for providing this more convenient and robust approach! As for the ToC lines for part and chapter, is there a key-value pair that controls how \addcontentsline gets called?, or how should I control those lines? I currently have the output but want the following output: My current (totally fragile) “solution” is to modify a copy of \__head_handle_marks_etc: \cs_set:Npn \__head_handle_marks_etc:nnnnn #1#2#3#4#5 { ... 23 lines of unchanged code ... \str_case:VnF{\l__head_name_tl} { {part}{\partname\space\thepart.\space} %% Custom ToC for Part {chapter}{\@chapapp\space\thechapter.\space} %% Custom ToC for Chapter } {\protect\numberline{ \use:c{ the \l__head_name_tl } } } %% Original code is fallback for Sections etc ... 8 lines of unchanged code ... } Is there a better way?

Is there a way to use custom reference format for one specific section in zref-clever? \documentclass{article} \usepackage{zref-clever} \usepackage{hyperref} \begin{document} \section{Regular section}\label{sect:I} \section{Named section}\label{sect:namedsectionII} \section{Regular section}\label{sect:III} When I reference \zcref{sect:I}, \zcref{sect:III} or any other section, I need it to be displayed as usual, but when I reference \zcref{sect:namedsectionII} specifically, I need the reference to look like ``somename,'' instead of ``section 2'' every time I reference it, with the hyperref link still leading to ``section 2.'' I know I can just use hyperref like this: \hyperref[sect:namedsectionII]{somename}, but I want to use the same zref-clever syntax for all the sections, be able define `somename' once, and, if necessary, turn this custom formatting off in one place. \end{document}

I have the following \documentclass[12pt,a4paper]{article} \usepackage{amsmath,amssymb} \usepackage{geometry} \usepackage{lipsum} \geometry{margin=2cm} \setlength{\parindent}{0pt} \renewcommand{\arraystretch}{1.25} \newsavebox{\leftbox} \begin{document} \begin{lrbox}{\leftbox} \begin{minipage}[t]{0.33\textwidth} \textbf{Given:}\hspace{2.5cm}\textbf{SI:} \vspace{2mm} \begin{tabular}{@{}l|l@{}} $m_1=120$ g & $0.12$ kg\\ $m_2=50$ g & $0.05$ kg\\ $c_1=4200\ \dfrac{\text{J}}{\text{kg}\cdot^\circ\text{C}}$ &\\ $c_2=920\ \dfrac{\text{J}}{\text{kg}\cdot^\circ\text{C}}$ &\\ $R=2\ \Omega$ &\\ $U=5$ V &\\ $\Delta t=12^\circ\text{C}$ &\\ $\eta=20\%$ &\\ \hline \multicolumn{2}{@{}l@{}}{\textbf{Find:}}\\ \multicolumn{2}{@{}l@{}}{$U-?$} \end{tabular} \end{minipage} \end{lrbox} \noindent \usebox{\leftbox} \hfill \begin{minipage}[t][\dimexpr\ht\leftbox+\dp\leftbox\relax][t]{0.64\textwidth} \textbf{Solution:} \vspace{2mm} \lipsum[1] \vfill \end{minipage} \lipsum[1-2] \end{document} which gives me this However I would like to write text in the right minipage as a continuous text without the need to break it (now it is causing problems with overlapping). I also would like to automatically left align the word 'SI' with the letters below it. It obviously comes from the fact that neither 'SI' or 'Given' are in the table, but that's on purpose - I need 'Given', 'SI' and 'Solution' to be on the same level vertically. How do I do that?

I have a complicated environment that scans for presence of tokens and "patches" them by adding some tokens before. I implemented this using macros with arguments delimited by the tokens I want to patch. Once the patching is done, I'd like to respect the token stream as much as possible (i.e. make it as close to the original as possible). However, whenever the text between the delimiters is exactly of the form "{ text }", the braces are sadly removed. I'd like to find a way to avoid this behavior. I had a look here but I'm afraid this will change the token stream too much, so I'm wondering if there is a simpler fix. Edit: Better MWE based on David's reply. Goal: Implement such a patch command so that the token stream after \patch is as close as possible (identical?) to the original one. \documentclass{article} \def\Z{Z} % Does not work with first def of \A \def\patch\A#1\Z{patched:\A#1\Z} % Does not work with second def of \A \def\patch\A#1{\xpatch\A{{#1}}} \def\xpatch\A#1\Z{patched:\A#1\Z} \begin{document} First def of A :\def\A#1{(A #1)} \A{arg} \Z \patch\A{arg} \Z \A{arg}\Z \patch\A{arg}\Z Second def of A:\def\A[#1]{(A #1)} \A[arg] \Z \patch\A[arg] \Z \A[arg]\Z \patch\A[arg]\Z \end{document} Output (first def of \A) (A arg) Z patched:(A arg) Z (A arg)Z patched:(A a)rgZ Thanks a lot for your help!

I am using the book class and tocloft package. The following code: \include{ch2} \addcontentsline{toc}{part}{Part II: 2-Dimensional Geometry} produces: in the t.o.c., which is a little more vertical space than I'd like. Is there a way of adding a spacing argument to the \addcontentsline command that determines its vertical position relative to the automatically generated subsection, or another simple way of reducing the spacing? (ideally not requiring a custom command)

The question was originated from the previous question and the comment: The offset implementation of A763043 would shift the path before decorations which means yshifting in the markings wouldn't be necessary, they would however be moved towards the postactions of the offsetting.

I am trying to get a matrix with an overbrace and sidebrace which looks like the following; I tried the following code so far, \documentclass[12pt]{article} \usepackage{epsfig} \usepackage{amssymb} %\usepackage[dvips]{color} \usepackage{amsmath} \usepackage{amsthm} \[ \begin{array}{ccc} \overbrace{\text{Col 1}}^{\text{Label A}} & %\overbrace{\text{Col 2 \quad Col 3}}^{\text{Label B}} & %\overbrace{\text{Col 4}}^{\text{Label C}} \\ \begin{bmatrix} a_{11} & a_{12} & a_{13} \\ a_{21} & a_{22} & a_{23} \\ a_{31} & a_{32} & a_{33} \end{bmatrix} \end{array} \] \end{document} But it is not giving the desired output. Kindly help.

I have a textbook, and from it I have derived slides. To ensure that the slide contents match the book's I use catchfilebetweentags. I'm now working on the book's new edition and this package still correctly fetches the material between the tags, but it now omits spaces where the source file book.tex has line endings. Here is the derived file slides.tex. \documentclass{article} \usepackage{catchfilebetweentags} \newcommand{\catchfilefn}{book.tex} \begin{document} Introductory text \ExecuteMetaData[\catchfilefn]{firsttag} \ExecuteMetaData[\catchfilefn]{secondtag} \end{document} Here is the source file book.tex. \documentclass{book} \usepackage{blindtext} \begin{document} \blindtext %<*firsttag> Contents of first tag. This is a sentence with a line break in the middle. %</firsttag> \blindtext %<*secondtag> Contents of \textit{second} tag. One word has an\index{test} index entry. %</secondtag> \blindtext \end{document} In the output slides.pdf there is no space between the tag. and This. Similarly there is no space between a and line. Linewise for tag. and One, and an and index. I have used this package for years and not seen this behavior (its last update on CTAN is 2011). I have today's TeX Live.

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}

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'm trying to make a worksheet where students need to fill out parts of a long division statement. I usually use the longdivision package, but realized that I can't cover up parts of it for students to fill out. Any suggestions? I've attached an image for reference.
