I'm writing a document with lots and lots of nicematrices. I'm setting this option at the beginning of the document: \NiceMatrixOptions{no-cell-nodes} This speeds up compilation considerably (as stated in the nicematrix documentation). The problem is that a few of my matrices need cell-nodes to render correctly. Is it possible to activate cell-nodes for just one nicematrix? One of this looks like this: \documentclass{standalone} \usepackage{nicematrix} \NiceMatrixOptions{no-cell-nodes} \begin{document} $ \begin{bNiceMatrix} a_{11} & a_{12} & \Cdots & a_{1n} \\ a_{21} & a_{22} & \Cdots & a_{2n} \\ \Vdots & \Vdots & \Ddots & \Vdots \\ a_{m1} & a_{m2} & \Cdots & a_{mn} \\ \end{bNiceMatrix} $ \end{document}

New Computer Modern has 8pt and 10pt fonts, e.g., NewCM08-Regular.otf and NewCM10-Regular.otf. How best to express, in the .fontspec file, the desire to use the 8pt font for 8pt or smaller, and the 10pt font everything else? Since "-8" means <8 and "8-" means >=8 (fontspec manual p.25), it seems it's necessary to specify 8 itself explicitly, as in: UprightFont={NewCM10-Regular.otf},% UprightFeatures={% SizeFeatures={% {% Size={-8},% Font={NewCM08-Regular.otf}% },% {% Size={8},% Font={NewCM08-Regular.otf}% },% {% Size={8-},% Font={NewCM10-Regular.otf}% },% }% },% It works but it's irritating. (I also couldn't find any actual statement in the fontspec doc that "first match wins". I hope that doesn't change.) So, my question: is there any shorthand for <=? Every font with multiple sizes (admittedly few) would want this, since it's better to scale down than to scale up. I know fontspec has an OpticalSize concept, but Antonis chose to implement the 8pt as a separate otf file, which seems reasonable. Neither lm nor drm nor the other "sized" otf files I could find have fontspec files for comparison (I guess since they have many more sizes, not so important). Not unlikely I missed something. Finally, here's a trivial LaTeX file to use the 8pt font. Without that middle "exactly 8" stanza above (or if it's after the 8-), the result is a scaled 10pt instead of the 8pt font. \documentclass{article} \usepackage{fontspec} \usepackage[olddefault]{fontsetup} \thispagestyle{empty} \begin{document} {\footnotesize A\par} \end{document}

I wrote the following code : \documentclass[11pt,a4paper,sans]{moderncv} \moderncvcolor{purple} \moderncvstyle{classic} \name{Abc}{Xyz} \email{\link[xyz@gmail.com]{xyz@gmail.com}} \begin{document} \makecvtitle \section{M.Sc Project} \cvitem{Subject}{Episode 111} \cvitem{Supervisor}{\link[Prof. CID]{https://youtu.be/lq-uW8NrlUU?si=ZK5JictkCnpC6Owt}} \end{document} Clicking on the email and clicking on the name of the supervisor takes me to the required links. But, my problem is neither the email nor the name of the supervisor is colored to distinguish it from the normal text. How can this be achieved ?

This post originated wipet's comment here and here: The solution has one disadvantage and should not be used commonly with massive usage of these symbols. Each occurrence of this symbol saves to the PDF file a new code with all coordinates of all curves. This is not the same as if the font is used. Then the font is loaded only once to the PDF file (with curves of used characters) and then each occurence of the symbol in the document is realized as a reference to the font and its slot-code. The PDF is smaller. You can use \pdfxform or you can save the symbols to an external pdf and use \pdfximage primitives. I point out that saving a tikz picture into a box and usage of this box saves computation time needed by tikz which converts svg format to pdf format of curves specification, but it doesn't solve the problems mentioned in my comments above. Ad saving Tikz computation: we need not to use TikZ at all: Load svg image to inkscape and export it to eps format. Then cut the curves specification in the eps output and copy it to the \pdfliteral parameter. TikZ is not needed, the curves have native pdf format. In summary, I see four possible approaches to add custom symbol support: modify the LatinModernMath-Regular-Private.otf, add glyph slots to private area apply svg.path solution to define the symbol put svg.path symbol in a box to use for multiple times use primitive for example \pdfliteral to declare the symbols ... My question was: what is the trade-off here? Is there exists the best-practice? Feature Method1: patch font .otf file Method2: svg.path directly Method3: svg.path with box Method4: \pdfliteral primitive Depends on External Files Yes No No No Supports All Engines only unicode engines all engines all engines all engines(?) Runtime Efficiency High Low High Generated PDF File Size Small Big Big Supports Native Character Operations, e.g. \bm Yes (if coorresponding glyph was added) No (see for example) The same as left Edit Thr rows and columns of the table above could be extended freely, for example: "using a vector image (e.g. pdf)" or "use the xsavebox package or the pdfxform-commands in l3pdfxform to store the box, then it is an xobject and only stored once in the pdf" References: How to tweak the svg-symbol baseline and size to act exactly the same as `\ell`? Is that possible to get symbol-family like \ell for "k" and "h" with computer/latin modern math style? https://tex.stackexchange.com/a/763942/322482 https://tex.stackexchange.com/a/763984/322482 https://github.com/user-attachments/files/29108768/LatinModernMath-Regular-Private.zip

I am currently formatting my thesis. The first draft is written in Computer Modern, and after another project that used non-LaTeX fonts through XeLaTeX, I was impressed by just how well-rounded the CM font system and especially the serif font is: Expressions written in math mode don't stand out at all, even when containing a mixture of roman and greek letters, numbers, and mathematical operators. To me, it is remarkable how every CM character perfectly harmonizes with its neighbors; its single lines are thin, which doesn't make a body of text seem fragile, but elegant and precise. However, no matter how much I re-discovered my appreciation for Computer Modern, it has one major disadvantage: I don't want to say that it's overused, but its choice in modern documents may seem rather bland or uninspired, since it is THE LaTeX default font (I have the same problem with Calibri, Aptos, and Times New Roman in Microsoft Word, but a huge difference to Word's default fonts is that CM is actually a very pretty font; it would be blasphemous to associate it with Calibri). I tried many different fonts in the LaTeX font catalogue (many seem too "bold" or not "uniform" enough to me), as well as possible approaches regarding XeLaTeX/LuaLaTeX. In many cases, math mode uses alternative fonts, which leads to very little harmony between math mode and text mode; in the rare case that the very same font is actually used for text mode and math mode and concludes a broad set of characters, pure text is quickly appealing to me, but mathematical expressions aren't. I just fail to find a font that approaches math mode and its harmony with text mode with the same perfection as CM does. Do you have any suggestions for fonts that have the same elegant, perfectionist feel as Computer Modern, but don't scream "I am a [very, very beautiful] default font!"?

Is there an elegant way to define subitems as arrows? I've tried the following code, however, it is quite a circumstance to have to add [$\Rightarrow] for every subitem \documentclass[hyperref={pdfpagelabels=false}]{beamer} \usepackage{lmodern} \usepackage[english]{babel} \usepackage[T1]{fontenc} \usepackage{amsmath, amsfonts, amssymb} \usepackage{amsthm} \usepackage{beamerthemeshadow} \begin{document} \section{Section 1} \begin{frame} \begin{itemize} \item Item 1 \begin{itemize} \item[$\Rightarrow$] Subitem 1 \end{itemize} \end{itemize} \end{frame} \end{document}

Is there a way to force the printing of the bibliography in subsections using beamer class?

How do I paste a long code here? For example when I click on "Code Sample" and paste the code, only the first line is inside the code block. Then I have to shift every other line by 4 spaces in order to get them into the block. Is there an effective way to do this?

Claim: I don't want to use pgfplots in this post. For the sake of I have already have a bunch of non-pgfplots code as below, I don't want to switch to pgfplots solution. The code is as below: \documentclass[tikz]{standalone} \usepackage{fourier-otf} \begin{document} \begin{tikzpicture} \draw[-latex] (0,0) -- (12,0) node[right] {Team}; \draw[-latex] (0,0) -- (0,26/4) node[above] {Number}; \foreach \y in {0,5,10,15,20,25} \draw (0,{\y/4}) -- (-0.1,{\y/4}) node[left] {\y}; \foreach \y in {5,10,15,20,25} \draw[gray!30] (0,{\y/4}) -- (11.5,{\y/4}); \foreach \name[count=\n] in {A,...,K} { \draw (\n,0) -- (\n,-0.1) node[below] {\name}; } %%%%%%%%%%%%%%%%%%% % \draw[thick] plot[mark=*, mark size=2pt, mark options={fill=black}] coordinates { % (1,16/4) (2,4/4) (3,12/4) (4,6/4) (5,5/4) (6,16/4) (7,17/4) (8,8/4) (9,8/4) (10,15/4) (11,11/4) % }; % \foreach \i[count=\n] in {16,4,12,6,5,16,17,8,8,15,11} { % \node[above=3pt] at (\n,\i/4) {$\i$}; % } %%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%% \foreach \i[count=\n] in {16,4,12,6,5,16,17,8,8,15,11} { \node[fill=black,circle,inner sep=2pt,label={above:$\i$}] (tmp-\n) at (\n,{\i/4}) {}; } \draw foreach \i[count=\last] in{2,...,11} {(tmp-\last) -- (tmp-\i)}; % %%%%%%%%%%%%%%%%%%%% \end{tikzpicture} \end{document} I would prefer the syntax of plot only in tikz: \draw[thick] plot[mark=*, mark size=2pt, mark options={fill=black}] coordinates { (1,16/4) (2,4/4) (3,12/4) (4,6/4) (5,5/4) (6,16/4) (7,17/4) (8,8/4) (9,8/4) (10,15/4) (11,11/4)}; \foreach \i[count=\n] in {16,4,12,6,5,16,17,8,8,15,11} { \node[above=3pt] at (\n,\i/4) {$\i$}; } However, I didn't find some way to label when plot. Thus I have to repeat the data \foreach \i[count=\n] in {16,4,12,6,5,16,17,8,8,15,11}{...} for the second time, which is not considered as a good practice. Any suggestions on how to do this similar without pgfplots? I don't want two forloop/plots as possible.

I'm trying to make a ltx-talk theme in the CI of our university. E.g., the CI request a line over the footer and a logo in the head, beside a two line header text. However, I'm afraid I haven't fully grasp the concept of templates. What exactly I have to declare or to overwrite? Do I need a new template type (but this would contradict the concept of templates, since the "idea" of a footer is still there), or a new interface, or template, or instance, and if so, how I can ensure that it is used? EDIT I'm not sure whether it will help, because my question is rather conceptional, but I was asked to provide my current code. This is my theme so far: \ProvidesExplPackage{talkthemetuc}{2026-06-16}{0.3.2}{TUC ltx-talk theme} \definecolor{tuccolor_tuc}{HTML}{005F50} \definecolor{tuccolor_inf}{HTML}{4A8246} % ... lots of other color definitions ... \definecolor{tuccolor_info}{HTML}{555555} \definecolor{tuccolor_warning}{HTML}{FF9900} \definecolor{tuccolor_danger}{HTML}{FF0000} \keys_define:nn {talkthemetuc}{ fakcolor .code = { \colorlet{tuccolor}{tuccolor_#1} \colorlet{structure}{tuccolor_#1} } } \ProcessKeyOptions[talkthemetuc]\relax \geometry{ tmargin = 1.8cm, headsep = 0.8cm, } \NewDocumentCommand \tucurl { = { short-tucurl } O { {#2} } m } { \keys_set:nn { talk / metadata } {#1} \tl_gset:Nn \@tucurl {#2} } \keys_define:nn { talk / metadata } { tucurl .tl_gset:c = @tucurl , short-tucurl .tl_gset:c = @shorttucurl } % header settings \EditInstance{header}{std}{ background-color = tuccolor, color = white, height = 1.8cm } % footer \DeclareInstance{footer-element}{tucurl}{talk}{} \EditInstance{footer-element}{framenumber}{ font = \small, left-hspace = 5pt \hfill, % this is a hack } \EditInstance{footer-element}{tucurl}{ font = \small, left-hspace = 5pt \hfill, % again } \EditInstance{footer-element}{author}{ font = \small, left-hspace = 1pt ·, % ... and again } \EditInstance{footer-element}{date}{ font = \small, } \EditInstance{footer}{std}{ color = black, separator = {\hspace{1pt}}, element-order = {date,author,framenumber,tucurl}, right-hspace = 3mm, left-hspace = 3mm, } And here is a one page presentation: \DocumentMetadata{tagging=on} \documentclass{ltx-talk} \usepackage[fakcolor=inf]{talkthemetuc} \title[Example]{Example Presentation} \subtitle{Shift from beamer to ltx-talk} \author[Joe Doe]{Prof. Joe Doe} \institute[TUC]{My University} \date{\today} \tucurl{www.a-nice.url} \begin{document} %\tuctitleframe % not yet implemented \begin{frame*} \frametitle{Motivation} \begin{itemize} \item The faculty color is a theme option. \item For multiple language version, we use the langselect package \item To set URL, use \verb!\tucurl{}! \end{itemize} \end{frame*} \end{document} The image shows the elements I've asked for:

I have noticed some weird behaviour: When using the biblatex-ext-tabular package and \clearname{author} (or \usebibmacro{tabular:omitsortname}), \DelcareFieldFormat{title}{...} does not seem to have any effect: \documentclass{article} \usepackage[style=ext-authoryear]{biblatex} \usepackage{biblatex-ext-tabular} \addbibresource{biblatex-examples.bib} \DeclareFieldFormat{title}{banana} \defbibtabular{bibtabular}{}{}{\driver{\clearname{author}}\\} \begin{document} \cite{baez/online} \printbibtabular \end{document} The title ("Higher-Dimensional Algebra V: 2-Groups") is shown, although it should have been replaced by "banana". (Of course, that's not a meaningful example, but sensitive formatting instructions are ignored as well.) Any idea, why?

Broad context: I am working on a presentation with other people in a git repository. I am writing a beamer theme that contains an EPS file. I am trying to make that theme reusable in other documents. I wrote my theme in a different directory, and compile with TEXINPUTS=assets/packages//: so lualatex can find it. I can't really install the package locally. Problem: the package cannot find its EPS image (see log below). It works with JPG or PNG, so this is most likely linked to epstopdf. Some solutions I have considered: Not using EPS. I really want to use EPS because other formats look horrible in my case. Stop that package nonsense and use \usepackage and \graphicspath with relative paths. I'd like to keep this theme generic however. Actually that's my main goal here. You will find a MRE below. I removed beamer from the equation.

Using the range option in unicode-math to override specific symbol ranges, I would have expected that both the script selection commands (\mathbb etc.) and direct input via Unicode characters (e. g. ℝ) would produce the same result from the overriding font. However, this does not seem to be the case: \documentclass{article} \usepackage{unicode-math} \setmathfont{TeX Gyre Pagella Math} \setmathfont{Latin Modern Math}[range={bb}] \begin{document} \noindent Unicode input: $ℝ$ \noindent mathbb input: $\mathbb{R}$ \end{document} Output: I saw the question “Tell unicode-math how to translate unicode symbols (script vs calligraphic)”, but initially thought that the behavior there was due to complications of \mathcal and \mathscr representing the same Unicode codepoints. Am I correct in assuming that range will actually never affect the output for Unicode characters appearing literally in the TeX source, and that these will always try to use the main math font that was defined without range?

When there is a displayed equation (say \begin{align*} first thing below section or subsection, the space between the section header and the equation is much larger than if the displayed equation was in middle with some text above it. Is there a way to make the space the same above the displayed equation, even if the equation is right below a section header? I tried adding this to preamble \setlength{\abovedisplayskip}{6pt} \setlength{\belowdisplayskip}{6pt} \setlength{\abovedisplayshortskip}{0pt} \setlength{\belowdisplayshortskip}{6pt} But the above had no effect. I can ofcourse add \vspace command with negative value above the displayed equation if it is first thing below section title, but this looks like a hack to me. Here is MWE. Compiled with lualatex using TL 2026 \documentclass[12pt]{article} \usepackage{amsmath} \begin{document} \section{Existence and uniqueness analysis} \begin{align*} y^{\prime}&=\left(x -2\right)^{2}\\ y \left(2\right) &= 1 \end{align*} This is a line here This is a line here This is a line here This is a line here \begin{align*} y^{\prime}&=\left(x -2\right)^{2}\\ y \left(2\right) &= 1 \end{align*} This is a line here This is a line here This is a line here This is a line here \begin{align*} y^{\prime}&=\left(x -2\right)^{2}\\ y \left(2\right) &= 1 \end{align*} \end{document} I also tried adding this to preamble but it had no effect \setlength{\abovedisplayskip}{3pt plus 1pt minus 2pt} \setlength{\abovedisplayshortskip}{0pt plus 1pt} \setlength{\belowdisplayskip}{3pt plus 1pt minus 2pt} \setlength{\belowdisplayshortskip}{3pt plus 1pt minus 2pt} Is there a global solution, I can add to preamble with having to manually use \vspace and such? Screen shot from actual latex pdf file I have: I do not like that extra vertical space above the first equation. I can rewrite things so first thing below section title is not an equation. But Latex should have solution not to add this extra space I thought.

Does anyone know if there are LaTeX codes for the old 17th- and 18th-century symbols for involution (powers) (kind of like an @ sign) and evolution (roots) (a sort of extended w)? Thanks. Thanks for all your assistance. According to Cajori's A History of Mathematical Notations (1928), p. 353 and pp. 213-214, the notation for involution and evolution go back to Johann Heinrich Rahn in his Teutsche Algebra (1659). However, Rahn used an Archimedean spiral to signify involution (he called it "involviren") (see https://old.maa.org/press/periodicals/convergence/math-origins-the-logical-ideas). Rahn's work was translated into English in 1668 by Thomas Brancker as *Added * and the Archimedean spiral was indeed replaced by the omicron-sigma ligature (with no explanation given; perhaps the typesetter had the ligature on hand). Ward, along with other English writers followed Brancker's notation. According to Cajori (p. 211), the sign for evolution is apparently a ligature of two epsilons.

The new template based section heading definitions which support tagging include a prefix option which is added before the section number. What is the correct way to include this in the TOC?
