There must be something wrong with the following code as it gives no errors but the wrong results. Changing the \getpagerefnumber to \getabspagerefnumber causes a huge number of errors.

I am looking for a specific LaTex font which I loved very much (especially for the lambda it produces) I have already asked a question for the lambda but my preamble was restricted by my institution. But now I just want to use that lambda for my own documents. I'm attaching my previous questions and efforts here: Using lambda in different font than that of the document I want this document to recreate specifically. If anyone knows the font then please do let me know.

So I was playing around with latex2sympy2 - a Python library to convert LaTeX to SymPy objects. I tried to run this code: from latex2sympy2 import latex2sympy latex_code = r"\begin{bmatrix} a & b \\ c & d \end{bmatrix}" print(latex2sympy(latex_code)) and ran into this: Exception: I expected something else here \begin{bmatrix} a & b \\ c & d \end{bmatrix} ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ It took me a while to figure out that the problem was d. I checked every letter instead of d and it worked correctly, run this so that you can see that yourself: from latex2sympy2 import latex2sympy for i in range(65, 91): if i == 69: continue # every letter except E print(chr(i), latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & %s \end{bmatrix}" % chr(i))) for i in range(97, 123): if i == 100: continue # every letter except d print(chr(i), latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & %s \end{bmatrix}" % chr(i))) # d try: print(latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & d \end{bmatrix}")) except Exception as e: print(f"{type(e).__name__}: {str(e)}") # E try: print(latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & E \end{bmatrix}")) except Exception as e: print(f"{type(e).__name__}: {str(e)}") I'm not good at LaTeX, though, please don't blame me. How do I fix that? I have no clues.

I'm trying to arrange a collection of nodes using \graph, which will be used to define a series of spath3 knot strands. However, the default cartesian placement strategy doesn't work very well for my purposes, as nodes chains that I intend to "tee off" from other nodes. It's possible to get what I want with the following code, but it's obviously rather fragile: \documentclass{article} \usepackage{etoolbox} \usepackage{tikz} \usetikzlibrary{calc, knots, positioning, graphs, graphdrawing} \usetikzlibrary{spath3} \begin{document} \begin{tikzpicture} \graph[nodes={draw, as={}}]{ a -> b -> c, {[placement/width=1, placement/depth=1, grow down] b -> d -> f -> g}, {[placement/width=2, placement/depth=2, grow right] f -> p}, }; \end{tikzpicture} \end{document} How can I achieve the same effect by specifying the node rather than the width and depth?

There is a highly popular post from 2014 showcasing Nice scientific pictures show off but a lot has changed with LaTeX over the last 12 years. What is your best science picture to show off now that wasn't possible 12 years ago? Constraints for each answer: The Picture & Code: Show off a beautiful scientific illustration that utilizes features, packages, or engine capabilities (e.g., LuaLaTeX memory handling, modern pgfplots limits, Luametafun) that remove barriers which routinely stopped typical users from doing this 12 years ago (such as hard memory crashes, lack of default ecosystem support, or prohibitive manual workarounds). The Evolution: You must explicitly explain what technological progress or package developmentover the last decade made this picture possible today. AI usage is allowed, but must be acknowledged per community guidelines.

In the following minimal example, I placed each Arabic word on a separate line to make it clear that first the exclamation mark follows the fifth (final) Arabic word. Using "bidi=basic", the 5 Arabic words appear in the desired order (RTL), but that 1st excl.mark appears between the first Arabic word and the English word "There's", whereas it ought to appear between the word "Example:" and the fifth Arabic word (i.e. the excl.mark should be included within the RTL context of the Arabic phrase). \documentclass{article} \usepackage[english,bidi=basic]{babel} \babelprovide[onchar=ids fonts]{arabic} \babelfont{rm}{FreeSerif} \begin{document} \pagestyle{empty} \paragraph{Example:} يا ناس ما كان باس ! There's nothing wrong! \end{document} The placement is the same when I put the entire Arabic phrase on one line, with the excl.mark immediately after the last Arabic letter. I understand why this is happening. Is there a way to force that excl.mark to be included within the RTL scope of the Arabic phrase? (Edited to add: With all the Arabic on one line, most (all?) bidi-capable displays make the same mistake: the "default" LTR context causes the excl.mark to appear to the right of the Arabic phrase; usually this can be fixed by putting the Unicode RLE character U+202b in front of the first Arabic letter, and "Pop Directional Formatting" U+202c after the excl. mark. Doing that in the .tex file has no effect.)

Using LuaLaTeX for a text in English that includes Cantonese characters and their IPA transliteration, all works fine, except that one diacritic symbol used for some final consonants (P, T, K) merge with the following tone symbol. The result is unreadable. Here is the MWE: \usepackage[english]{babel} \usepackage{fontspec} \babelfont{rm}{TeX Gyre Pagella} \babelprovide[import=yue]{cantonese} \babelfont[cantonese]{rm}[Renderer=Harfbuzz]{Noto Sans HK} \babelfont[tipa]{rm}[Renderer=Harfbuzz]{FreeSans} \usepackage[dvipsnames]{xcolor} \DeclareRobustCommand\gdg[1]{\textcolor{CadetBlue}{\foreignlanguage{cantonese}{#1}}} \DeclareRobustCommand\gdgp[1]{\textcolor{MidnightBlue}{\foreignlanguage{tipa}{[\,{\footnotesize #1}\,]}}} \begin{document} This transliteration without the issue: \gdg{廣州} \gdgp{kʷɔːŋ² tsɐu¹} Here is one example of the problematic case: \gdg{百越} \gdgp{paːk̚³ jyːt̚⁶} \end{document} After compilation, the unreleased stop diacritic, also known as "combining left angle above", UNICODE U+031A, directly merges into the following tone number in superscript. Hence my question: is there a possibility to include a space that would apply only after this diacritic stop symbol and not before any tone number? Thank you in advance for any help or suggestion

I want to add some tagged section headings within frames with ltx-talk. It seems like using the exisiting section templates would be a neat way of doing this. But I am having trouble getting the section tagging structure to close correctly at the end of the frame. I can't find a way to inject sockets to close things without redefining internal ltx-talk macros. And so far, I haven't closed things correctly in all situations even if I do redefine. This seems to work in most cases I try, but seems risky: \cs_set_protected:Npn \__talk_frame_process:nn #1#2 { \__talk_decode_parse:n {#1} \bool_if:NT \l__talk_decode_mode_bool { \__talk_frame_process_aux:nn {#1} { #2 \par \UseTaggingSocket{sec/end}{6} \UseTaggingSocket{sec/end}{5} } } } What is a good way of doing this?

I just upgraded my MacTeX-2025 to MacTeX-2026 and now the texi2dvi command is not available anymore. I am pretty sure, I could use it before, but it seems to be completely gone. I also don’t find it in '/usr/local/texlive' and '/Library/TeX/texbin'. Has this been removed on purpose or is my install bad for some reason?

I am on MacOS (Tahoe and in while Golden Gate...). I have MacTeX (i.e. Texlive, basically) and it works. The only thing that troubles me is that I have to keep many many packages which I do not use. On other MacOS machine I have MikTeX and what is good about it is that you only have (mostly) only the packages you use, as you know. Now I do have space on the Mac where I have MacTeX but still it troubles me to have a few GB wasted. I was thinking about installing BasicTeX and then adding the packages I need. I am a fairly advanced tex user and I am also sure that I need quite a few more packages than BasicTeX will provide. I could install MikTeX but it still uses Rosetta and it is not clear to me what will happen when Apple will drop support for it. I am asking to fellow tex users who had experience about BasicTeX on Mac: Would the GUI interface for packages still be there, or I'll need to install via terminal tlmgr command? Under the assumption that I need (for sure) many packages more than provided by BasicTeX would this solution be workable, under your experience?

Let $G$ be a graph with vertex set $V(G)=\{1,2,\dots,n\}$ and edge set $E(G)=\{e_1, e_2,\dots,e_m\}$. We use the notation $i\sim j$ to mean that the vertices $i$ and $j$ are adjacent. The\textbf{\textit{ adjacency matrix}} of $G$, denoted by $A(G)$, is defined as $A(G)=[a_{ij}]_{n\times n}$, where \\ \\ \indent \indent \indent \indent \indent \indent \indent \indent \indent \indent $a_{ij}=\begin{cases} 1, & \text{if } i \sim j\\ 0, & \text{otherwise.} \end{cases}$ \\ \\ The \textit{\textbf{Laplacian matrix}} of $G$, denoted by $L(G)$, is defined as $L(G) := D(G)-A(G)$, where $D(G)$ is the diagonal matrix with degrees of the vertices of $G$ as diagonal entries. It is well-known that $L(G)$ is symmetric and positive semidefiniite and rank of $L(G)$ is $n-k$ where $k=k(G)$ is the number of connected components in $G$. Since $L(G)$ is symmetric and positive semidefinite so all the eigenvalues of $L(G)$ are real and non-negative. Moreover, $0$ is the smallest eigenvalue of $L(G)$ as for $v=(1 \ \ 1\ \dots \ 1)^T \in \R^n$, \ \ $L(G)v=0v$. \par Suppose that $0=\lambda_1\leq \lambda_2 \leq \cdots$ \section{Preliminaries} \section{Work done} Maximum 03 pages \section{Further study} Maximum 01 page \begin{thebibliography}{33} \bibitem{F1} Castelaz, A.~Commutivity degree of finite groups.~Thesis,~Department of Mathematics,~ Wake Forest University,~North Carolina,~5-8, 2010. \bibitem{C1} Cerf, V.,~Fernandez, E.,~Gostelow, K.,~and~Volausky, S.~ Formal control and low properties of a model of computation.

I'm writing a thesis, and as part of my initial attempt to organise myself I ultimately made a small database which I want to include as one of my appendices. I've exported all the tables into .txt format, and I'm using DataTool to import them a page at a time. However, I'm having a lot of trouble formatting them. What I want is ultimately for it to look nice and for the columns to all fit into their page. I'd also really like to fix the page number orientation on the landscape page, but I've been struggling to even make the table cooperate. The Thesis style uses the base class "Book". Swapping to \documentclass{book} breaks a whole lot thanks to the new commands introduced, so I'm supplying the full Thesis.cls file here.

I want to recreate a chapter title page like this one (French math textbook): The design has: A grey background band at the top with the word "Chapitre" in blue serif italic. A blue horizontal banner containing: The chapter number inside a white double-framed box, slightly overlapping the banner (sticking out to the left). The chapter title in white, centered. A blue vertical bar on the left edge of the page (partially visible). Below, several centered "info boxes" (Niveau, Volume horaire, Degré d'importance) with a white fill, thin black frame, and a thick black offset shadow behind them. I tried with tcolorbox but I can't get: the number box to overlap the banner edge like in the picture, the offset shadow on the info boxes.

For that, I have the user command latexmk -cd -pdf -synctex=1 -interaction=nonstopmode -file-line-error -outdir=../pdf -auxdir=../aux %.tex as user0 and my main tex files look like this: % !TeX program = user0 \documentclass{article} \begin{document} content, includes other tex files that are in a subfolder of tex \end{document} Everything works, but if I have an error I do not get the usual error message that tells me what error I have and in which line. What can I do so that I still get error messages?

I would like to use forloop (or multido or another alternative if suggested) so that I can generate a series of short coding quizzes where each quiz uses verbatim (or fancyvrb or listings or another alternative). But when I try to do this: \documentclass{article} \usepackage{forloop} \newcounter{x} \begin{document} \forloop{x}{1}{\value{x} < 7}{% \begin{verbatim} def f(x): return x + 1 \end{verbatim} } \end{document} I get an error: File ended while scanning use of \@xverbatim The same basic problem has occurred when I have tried using multido rather than forloop; likewise fancyvrb or listings instead of verbatim. Is there anyway around this limitation?

Consider the code: \documentclass[12pt]{book} \usepackage{tabularx,lipsum} \begin{document} \thispagestyle{empty} \begin{tabularx}{\linewidth}{c>{\arraybackslash}X} \emph{Heading:} \emph{(to go on second line)} \hskip 15pt & \lipsum[13] \end{tabularx} \end{document} which produces QUESTION: How may I place Heading: (on the second line) over two lines: Heading and (on the second line)? (\vspace{5pt} or \vspace*{5pt} neither seem to work; and, \\[5pt] gives me an overflow message.) Thank you.

I'm having issues with a specific bibliographic entry. While all other citation call-outs in the document work fine, one shows up as sacco˙neurite˙2020 instead of as "(Sacco et al., 2020)" when I use \cite{sacco_neurite_2020}. Here, sacco_neurite_2020 is the correct key that is in Zotero and also in references.bib. The full entry in references.bib is the following: @article{sacco_neurite_2020, chapter = {Adult Brain}, title = {Neurite {Orientation} {Dispersion} and {Density} {Imaging} for {Assessing} {Acute} {Inflammation} and {Lesion} {Evolution} in {MS}}, volume = {41}, copyright = {© 2020 by American Journal of Neuroradiology.

I am new to listings package. I am on macOS using the complete TeXLive install 2026 and nvim. In the file /usr/local/texlive/2026/texmf-dist/tex/latex/listings/lstlang2.sty are three versions of Lua defined with nr like 5.0 - do I have to add this to my tex request for language Lua? A path error is excluded: kpsewhich lstlang2.sty # Output: /usr/local/texlive/2026/texmf-dist/tex/latex/listings/lstlang2.sty Permission error is excluded: ls -l /usr/local/texlive/2026/texmf-dist/tex/latex/listings/lstlang2.sty -rw-r--r-- 1 root wheel 106030 Nov 20 2025 /usr/local/texlive/2026/texmf-dist/tex/latex/listings/lstlang2.sty Here a minimal (non) working example: \documentclass{article} \usepackage{listings} % \input{listings-lua.prf} % Define Lua manually (bypassing the broken auto-loader) % \lstdefinelanguage{Lua}{ % keywords={and,break,do,else,elseif,end,false,for,function,if,in,local, % nil,not,or,return,true,then,until,while}, % sensitive=true, % morecomment=[l]{--}, % morestring=[b]\", % morestring=[b]' % } \begin{document} \begin{lstlisting}[language=Lua] print("Hello, Lua!") \end{lstlisting} \end{document} Compiling with lualatex in zsh.

In beamer, I want all the solution environments' contents to appear in normal beamer mode but disappear in handout mode. Typically this can be achieved by something like \documentclass[handout]{beamer} \begin{document} \begin{frame} \begin{example} example text \end{example} \begin{solution}<2-|handout:0> solution text \end{solution} \end{frame} \end{document} However, adding handout:0 for every solution environment is tedious. Is there any automatic may?

I already know \left<opening operator> <content> \right<closing operator> automatically scales up the operators to adapt to the <content> size. I have the opposite problem: I want to scale a set of parentheses down, specifically in a superscript. Take the symbol below in (1) which I use to refer to a specific curve in my paper. I sometimes want to take the first derivative of it, which needs a \prime in superscript, leading to (2). % (1) The regular curve symbol. \NewDocumentCommand{\curve}{m}{% \phi_{\vphantom{m}\smash{f}}^{\text{\upshape gen}}% \IfBlankF{#1}{(#1)} }% % (2) Its derivative \NewDocumentCommand{\curvederivative}{m}{% \phi_{\vphantom{m}\smash{f}}^{\text{\upshape gen}\prime}% \IfBlankF{#1}{(#1)} }% However, these can easily be confused. I want to add parentheses around the \prime in order to make the difference stand out. The problem is the parentheses have a lot of height, but no depth (quite the change compared to the "gen" text, only having depth). This version also adds some height to the surrounding line in text mode... % (3) My attempt with parentheses... \NewDocumentCommand{\curvederivativeparen}{m}{% \phi_{\vphantom{m}\smash{f}}^{\text{\upshape gen}(\prime)}% \IfBlankF{#1}{(#1)} }% Is there an automatic way to scale the parentheses down to the size of the content (in that case, only the \prime symbol)? I know I can play around with \scalebox and \raisebox, but I don't want to fiddle with the lengths if the content changes...

I try to use Emacs + AUCTeX + Miktex to compile the following code which fails to output the index I expect. The options of the engine is: (add-to-list 'TeX-command-list '("XeLaTeX" "%`xelatex -shell-escape -aux-directory=./tmp -recorder %(mode)%' %t" TeX-run-TeX nil t)) Then I remove the option -aux-directory=./tmp and the index is created. But temporary files created during compilation are now all located in root path which is very annoying. How to get my index automatically created with imakeidx and meanwhile put all the temporay files in a given path? \documentclass{article} \usepackage[nonewpage]{imakeidx} \makeindex[columns=3,intoc,title=My Index] \begin{document} The first index needed\index{index}\\\clearpage The second index needed\index{second} \printindex \end{document}

I'm writing a lemma with italics font style where I need enumeration in lowercase Roman numerals. I tried different ways and the best I could do is to use the package enumerate like this: \usepackage{enumerate} \begin{document} \begin{lemma} For any graph G, \begin{enumerate}[(i)] \item L(G) is symmetric. \item L(G) is positive semidefinite. \item etc. \end{enumerate} \end{lemma} \end{document} But the problem I'm facing is the tilts of parentheses are more than that I like. Actually I want like this: Any help would be appreciated.

Today I tried to use biber (within TeXShop) and I got this error in the console: usage: lipo <input_file> <command> [<options> ...] command is one of: -create[_album] -info -detailed_info -thin <arch> -extract <arch> [-extract <arch> ...] -remove <arch> [-remove <arch> ...] -replace <arch> <file_name> [-replace <arch> <file_name> ...] -verify_arch <arch> ... -archs options are one or more of: -arch <arch> <input_file> -o <output_file> -segalign <arch> <alignment> /Library/TeX/texbin/biber: extracting arm64 binary with lipo failed (wstatus=256) All of the error makes no sense to me. But when I google that last line, it says that it "does not contain the arm64 architecture slice." I'm wondering if this is an error having to do with the upcoming updates in the OS (???). If anyone has a solution or even a description of what is going on, I'd appreciate the help.
