I'm reproducing this educational graphic for my Algebra 1 students: I'm drawing fractions manually (separate nodes for numerator, bar, denominator) rather than \frac{}{} so I can control individual font sizes and colors. Two spacing problems I can't fix: 1. The fraction bar crashes into the 2 superscript on the denominator 5² 2. (where a ≠ 0) has no breathing room below the denominator aⁿ Both stem from the bar and note being placed at hardcoded absolute y-coordinates with no structural relationship to the surrounding nodes. MWE (problem area marked): % ── PROBLEM 1: bar hardcoded at y=1.88, unrelated to midfive.north ── \node[font=\bfseries\fontsize{38}{38}\selectfont] (midfive) at (11.70,1.03) {5}; \node[font=\bfseries\fontsize{22}{22}\selectfont] at ($(midfive.north east)+(0.08,0.10)$) {2}; \draw[line width=1.8mm] (11.18,1.88) -- (12.22,1.88); % bar too close to "2" % ── PROBLEM 2: note hardcoded at y=0.78, unrelated to aden.south ── \node[font=\bfseries\fontsize{41}{41}\selectfont] (aden) at (5.76,1.52) {a}; \node[font=\bfseries\fontsize{24}{24}\selectfont] at ($(aden.north east)+(0.10,0.12)$) {n}; \node[font=\bfseries\fontsize{15}{15}\selectfont] at (4.22,0.78) {(where a $\neq$ 0)}; Full MWE: \documentclass[tikz,border=0pt]{standalone} \usepackage{fix-cm} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{lmodern} \usepackage[scaled=0.98]{helvet} \renewcommand{\familydefault}{\sfdefault} \usepackage{xcolor} \usetikzlibrary{calc} \definecolor{bggray}{HTML}{ECECEC} \definecolor{purpleA}{HTML}{6B2FEA} \definecolor{purpleB}{HTML}{8B43F5} \definecolor{purpleText}{HTML}{7A34F0} \definecolor{greenText}{HTML}{43D400} \definecolor{redExample}{HTML}{FF2946} \definecolor{textMain}{HTML}{202020} \newcommand{\Avar}{\textcolor{purpleText}{\textbf{a}}} \newcommand{\Nvar}{\textcolor{greenText}{\textbf{n}}} \newcommand{\NegNvar}{\textcolor{greenText}{\textbf{-n}}} \begin{document} \begin{tikzpicture}[x=1cm,y=1cm] \path[use as bounding box] (0,0) rectangle (16,9); \fill[bggray] (0,0) rectangle (16,9); \shade[left color=purpleA,right color=purpleB] (0,6.82) rectangle (16,9); \node[text=white, font=\bfseries\fontsize{28}{30}\selectfont] at (8,8.18) {Negative Exponent Rule}; \node[anchor=north west, text=textMain, align=left, text width=15.0cm] at (0.56,6.47) {% {\bfseries\fontsize{12.6}{18}\selectfont Any nonzero number, \Avar, raised to a negative exponent, \NegNvar,\\[5pt] equals one over that number raised to the positive exponent, \Nvar.} }; \draw[black, line width=1.1mm, rounded corners=1.2mm] (1.02,0.35) rectangle (7.42,4.34); \node[text=purpleText, font=\bfseries\fontsize{53}{53}\selectfont] (abase) at (2.08,2.56) {a}; \node[text=greenText, font=\bfseries\fontsize{26}{26}\selectfont] at ($(abase.north east)+(0.18,0.16)$) {-n}; \node[text=textMain, font=\bfseries\fontsize{34}{34}\selectfont] at (4.18,2.62) {=}; \node[text=textMain, font=\bfseries\fontsize{36}{36}\selectfont] at (5.78,3.42) {1}; \draw[line width=2.0mm] (5.12,2.63) -- (6.44,2.63); \node[text=purpleText, font=\bfseries\fontsize{41}{41}\selectfont] (aden) at (5.76,1.52) {a}; \node[text=greenText, font=\bfseries\fontsize{24}{24}\selectfont] at ($(aden.north east)+(0.10,0.12)$) {n}; \node[text=textMain, font=\bfseries\fontsize{15}{15}\selectfont] at (4.22,0.78) {(where \Avar\ $\neq$ 0)}; % PROBLEM 2 \fill[redExample] (8.86,3.10) rectangle (14.78,4.20); \node[text=white, font=\bfseries\fontsize{21}{21}\selectfont] at (11.82,3.65) {Example}; \node[text=textMain, font=\bfseries\fontsize{44}{44}\selectfont] (fivebase) at (9.62,1.70) {5}; \node[text=textMain, font=\bfseries\fontsize{24}{24}\selectfont] at ($(fivebase.north east)+(0.08,0.12)$) {-2}; \node[text=textMain, font=\bfseries\fontsize{34}{34}\selectfont] at (10.58,1.85) {=}; \node[text=textMain, font=\bfseries\fontsize{34}{34}\selectfont] at (11.70,2.53) {1}; \draw[line width=1.8mm] (11.18,1.88) -- (12.22,1.88); % PROBLEM 1 \node[text=textMain, font=\bfseries\fontsize{38}{38}\selectfont] (midfive) at (11.70,1.03) {5}; \node[text=textMain, font=\bfseries\fontsize{22}{22}\selectfont] at ($(midfive.north east)+(0.08,0.10)$) {2}; \node[text=textMain, font=\bfseries\fontsize{34}{34}\selectfont] at (13.18,1.85) {=}; \node[text=textMain, font=\bfseries\fontsize{34}{34}\selectfont] at (14.35,2.53) {1}; \draw[line width=1.8mm] (13.86,1.88) -- (14.84,1.88); \node[text=textMain, font=\bfseries\fontsize{36}{36}\selectfont] at (14.35,1.00) {25}; \end{tikzpicture} \end{document} What is the canonical way to: Position a manually-drawn fraction bar so it reliably clears a denominator's superscript, using node anchors rather than hardcoded y-coordinates?

Does anyone know if either of these two Pinocchio fonts (or a reasonable facsimile thereof) is available in LaTeX (font cataglogue)? Does anyone know the name of these two fonts by which the word "Pinocchio" is typeset in white?

I want to be able to easily comment out selected parts of my document, e.g., „Sentence two“ in the following example. It seems that, LaTeX interprets a newline as a space (except if the previous line ended with a comment) ignores double spaces (ex. 6) and thus also newlines preceded by a space (ex. 2) Does this hold for every scenario? Is there anything I should be aware of? Or can I replace all of my spaces by newlines? So example 3 is the best way to go? \documentclass{article} \begin{document} % 1. Normal written Sentence one. Sentence two. Sentence three. % 2. Space at end of every row Sentence one. Sentence two. Sentence three. % 3. No spaces at end of row Sentence one. Sentence two. Sentence three. % 4. Comment at end of every row Sentence one.% Sentence two.% Sentence three. % 5. Space and comment at end of every row Sentence one. % Sentence two. % Sentence three. % 6. Double spaces (bonus) Sentence one. Sentence two. Sentence three. \end{document}

Me and my friends are currently following a LuaLaTeX/PDF-UA accessibility workflow that recommends wrapping floating elements such as figures and tables using \tagstructbegin and \tagstructend. However, we have encountered an issue with tables. When we wrap a table with “\tagstructbegin{tag=Part}” and “\tagstructend”, veraPDF reports structure-tree errors and the document fails PDF/UA validation. However, if we remove the tag structure entirely, the table passes veraPDF validation and is read correctly by screen readers (VoiceOver in our testing). Because of this, we are unsure which approach is correct. Should we remove the manual tag structure for tables, or is there a recommended way to use tagpdf with tables that avoids these validation errors? Below is a simplified example of the table structure we are using: \tagstructbegin{tag=Part} \begin{table}[H] \caption{Sample data for Cu powder pattern} \makebox[\textwidth][c]{ \begin{tabular}{|c|c|c|c|c|} \hline $sin^2\theta$ & $sin^2\theta/0.1369$ & $(sin^2\theta/0.1369)*3$, rounded & hkl \\ \hline 0.1369 & 1 & 3 & (111)\\ 0.1809 & 1.32 & 4 & (200)\\ 0.3642 & 2.66 & 8 & (220)\\ 0.5012 & 3.66 & 11 & (311)\\ 0.5455 & 3.98 & 12 & (222)\\ \hline \end{tabular} } \label{XRD:table2} \end{table} \tagstructend The VeraPDF error report is: "When present, the Caption element shall be the first or the last child of the structure element". Thanks for your help!

Without the \DocumentMetadata, everything works fine. I also tried tagging=off but that makes no difference.

I use latex generated by computer algebra systems. So I can't change it as each time the program run, it will be overwritten. Also Scientific word generates such latex. All math tex work OK with lulatex. My understanding so far, is that same tex code works as is in context as with lualatex because context uses same tex engine also as lualatex. And I only need to change the surrounding latex commands to context commands. i.e. change \begin{align*} to \startformula and so on. But the tex generated will still work. Here is example where it does not work. First lualatex \documentclass[12pt,oneside]{book} \usepackage{amsmath} \begin{document} \[ x^{\prime \prime } =50 \sin \left (5 t \right )%autogenerated \] \end{document} compiled gives Here is context file \starttext \startformula x^{\prime \prime } =50 \sin \left (5 t \right ) \stopformula \stoptext Compiled using context gives If some tex code do not work same way as in Lualatex, then using context will not work for me, as 90% of the tex code I use is generated by other programs. Would someone clarify this aspect of context?

in lualatex this MWE (thanks to answer Why making integral sign upright works for some fonts but not others?) \documentclass[12pt,oneside]{book} %\usepackage{amsmath} %loaded by unicode below \usepackage{unicode-math} \setmainfont{STIX Two Text} \setmathfont{STIX Two Math}[StylisticSet=8] %sets integral sign up \begin{document} Regular text automatically uses STIX Two Text. \[ \int_a^b f(x) \, dx = F(b) - F(a) \] \end{document} Gives How to get same result in context?

Your integral sign is now completely upright: \startformula \int_a^b f(x) \, dx = F(b) - F(a) \stopformula \stoptext Compiled using context A.tex gives I've been talking with google AI on this for last 30 minutes and it gave me about 20 different codes to try, none of them worked.

I want to use some lua code, which gives me a string, and then be able to define macros (the latex way) using the result. I would have thought something like this would work: \documentclass{article} \newcommand\foo\directlua{ tex.print("foobar") } \begin{document} % Expected 'foobar', got an error. \foo \end{document} But instead I get an error saying 'missing begin document'. What's going on? Context For context: I have a general macro, defined with Lua, which fetches and prints external information. I want to use this macro to parametise some documents, with the option to override the parameter using a user macro. Something like this: \documentclass{article} % This would go in the .cls file \makeatletter % Default value \let\@email\externaldata{email} % Command for overring \newcommand{\email}[1]{\xdef\@email{#1}}% \makeatother \begin{document} % \@email can still be printed here without the user having to use % \email, because of the externally-sourced fallback. \end{document} Where \externaldata is my (custom, local) macro for getting the externally-defined data. This is why I don't just define the macros inside the Lua code. TIA!

How can I have the same alignment for the open access icon from the biblatex-ext package even when used in a quote or itemize environment? The open access icon is aligned properly when using a plain fullcite or in the bibliography and sits on the baseline of the first line. When used in a quote or itemize environment however, the alignment is off.

Following up this question: I am using Sam Carter's answer to get the spacing right. I modified the "ingredients part" of the xcookybooky package to fit my needs - now there are two tables (using tabular resp. tblr) and an image in this part. If I do this, the wrapfig of the ingredients does not work as intended. Either all steps are "short" or all are "long" but the first ones should be short, the ones after the ingredients long. How can that be changed? Since I modified the package, I tried to add the lines for this part manually in the following MWE - this does not give the same problem but a (maybe) related: No matter which number ist insert after \wraptable, the line of step 4 are too long.

Edit: essentially duplicate of redefining \label and \ref when using hyperref, noting that one more redefinition is needed with amsmath (Using custom \locallabels command with custom \eqref command). I'm trying to redefine \label and \ref to automatically append label by \themycounter: (where mycounter is a counter I use to avoid overlapping labels in a larger project made from multiple pieces). The approach in MWE below works well when hyperlinks is not loaded. As soon as I uncomment \usepackage{hyperlinks} the setup breaks, as if Latex was ignoring my attempt at redefining \ref (in the example below, with hyperlinks loaded \ref{0:e1} works). How should I fix it (and why is it broken in the first place)? MWE: \documentclass{article} %\usepackage{hyperref} \newcounter{mycounter} \let\oldlabel\label \renewcommand{\label}[1]{\oldlabel{\themycounter:#1}} \let\oldref\ref \def\ref#1{\oldref{\themycounter:#1}} \begin{document} \begin{equation}\label{foo} 1=1 \end{equation} \ref{foo} %\ref{0:foo} <-this creates a correct reference with hyperlinks loaded \end{document}

I'm writing a novel which has a few footnotes. In some special cases, I only have two or maybe three (max !) footnotes on the same page. I would like to get the same dagger symbol for all footnotes on each page, if there's only a single footnote, and the dagger and double-dagger on the pages that get two footnotes at bottom. How can I achieve this? Usually, for technical documents, I use the default numbers. But I need to change that to daggers and double-daggers only, with a recount on each page. In the very rare case where I would need a third footnote on the same page, I would prefer the old style paragraph symbol, or another better one. If possible, I would prefer to not load any new package, since my full document preamble is already pretty heavy... Here's a MWE to play with, which currently isn't doing what I'm looking for: \RequirePackage[l2tabu,orthodox]{nag} \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} % Option : stretch=50 \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt]{geometry} % Option showframe pour montrer les bordures. \raggedbottom \setlength{\parindent}{1.5em} \linespread{1.1} \usepackage[bottom]{footmisc} \usepackage{titlesec} \usepackage{graphicx} \usepackage[dvipsnames]{xcolor} \usepackage{float} \usepackage{fancyhdr} \usepackage[titles]{tocloft} \usepackage[unicode,colorlinks,linkcolor=Blue,urlcolor=Red,citecolor=blue,pdftitle={title},pdfauthor={Author},pdfsubject={Subject},pdfkeywords={Words},pdfproducer={pdfLaTeX},plainpages=false,hyperindex=true,pdfpagelabels,linktocpage=true]{hyperref} % Footnote symbol: \renewcommand{\thefootnote}{\fnsymbol{footnote}} \begin{document} Blablabla\footnote{Bla bla.}.

Here is my MWE: % !TEX program = lualatex \documentclass{article} \usepackage[no-math,otfmath]{newpx} % Loads unicode-math \setmathfont{Asana Math} \setmathfont{STIX Two Math}[version=stix-two-math] % \setmathfont{STIX Two Math}[ % range={ % \assert, % \Dashv, % \dashv, % \models, % \vDash, % \vdash, % } % ] \begin{document} \section{Asana Math} {\Huge\[\assert\vdash\dashv\]} {\Huge\[\models\vDash\Dashv\]} \section{STIX Two Math} \mathversion{stix-two-math} {\Huge\[\assert\vdash\dashv\]} {\Huge\[\models\vDash\Dashv\]} \end{document} In my personal documents, I often use Asana Math as the primary OpenType math font and STIX Two Math as the secondary OpenType math font (for glyphs which the former lacks or which I simply prefer). Judging from the glyphs in other fonts seen in List of symbols defined by the package [unicode-math], it seems that Asana Math's glyphs for \models (U+022A7 ⊧) and \vDash (U+022A8 ⊨) may have been, perhaps unintentionally, swapped. I am aware I can simply uncomment lines 6–15 in my MWE in order to use STIX Two Math's glyphs. I wanted to ask if there was a way to unswap the corresponding Asana Math glyphs, or swap the corresponding symbol definitions if the math font currently used for those symbols is Asana Math so as not to affect their original definitions when other math fonts are used instead in the document.

Following the "cite" feature of this Math.SE question using bibtex, I get: @MISC {5023954, TITLE = {A reference request for quasisimple groups being one-headed.}, AUTHOR = {Nicky Hekster (https://math.stackexchange.com/users/9605/nicky-hekster)}, HOWPUBLISHED = {Mathematics Stack Exchange}, NOTE = {URL:https://math.stackexchange.com/q/5023954 (version: 2025-01-17)}, EPRINT = {https://math.stackexchange.com/q/5023954}, URL = {https://math.stackexchange.com/q/5023954} } This seems incorrect, and I don't know how to correct it. Please would you recommend how I can get it to be like MSE sample citation?

I am preparing a presentation in Beamer and using biblatex for my references. My slides contain a mixture of inline and displayed mathematics, and I have noticed that some equations appear with different spacing or font sizes depending on the surrounding environment. For example, I would like the following: Inline math should have a consistent appearance throughout the presentation. Displayed equations should have the same spacing whether they appear inside a block or directly on the frame. Using biblatex should not interfere with the formatting of mathematical expressions. The solution should work with standard Beamer themes. MWE: \documentclass[10pt]{beamer} \usetheme{Frankfurt} \usepackage{amsmath} \usepackage{mathtools} \usepackage{filecontents} \begin{filecontents}{\jobname.bib} @book{lamport, author = {Leslie Lamport}, title = {LaTeX: A Document Preparation System}, year = {1994}, publisher = {Addison-Wesley} } \end{filecontents} \usepackage[backend=biber,style=numeric]{biblatex} \addbibresource{\jobname.bib} \begin{document} \begin{frame}{Math example} Some inline math such as \(a^2+b^2=c^2\) is followed by a citation \cite{lamport}. \begin{block}{Displayed equation} \[ \int_{0}^{1} x^2\,dx=\frac13. \] \end{block} Outside the block: \[ \sum_{k=1}^{n} k=\frac{n(n+1)}{2}. \] \end{frame} \end{document} Is there a recommended way to ensure that inline and display math are formatted consistently throughout a Beamer presentation while continuing to use biblatex for citations?

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}

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!"?

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:

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.

Although I wrote a LaTeX-like design for Taiwanese train station signs, the resemblance is still somewhat lacking. https://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/ROC_Taiwan_Railways_Administration_Logo.svg/960px-ROC_Taiwan_Railways_Administration_Logo.svg.png \documentclass{article} \usepackage{xeCJK,amssymb} \usepackage[ paperwidth=5in, paperheight=3in, margin=0.2in ]{geometry} \usepackage{graphicx} \usepackage{tikz} \pagestyle{empty} \begin{document} \begin{tikzpicture}[remember picture,overlay] \node[anchor=north west, xshift=0in, yshift=0in] at (current page.north west) { \includegraphics[width=0.5in,height=0.5in]{960px-ROC_Taiwan_Railways_Administration_Logo.svg.png} }; \end{tikzpicture} \begin{tikzpicture}[remember picture,overlay] \node[align=center, text=black, yshift=0.25in] at (current page.center) { {\fontsize{28pt}{34pt}\selectfont Miaoli} \\[0.2em] {\fontsize{32pt}{38pt}\selectfont 苗栗} }; \end{tikzpicture} \begin{tikzpicture}[remember picture,overlay] \node[ draw, line width=0.8pt, minimum size=0.9in, inner sep=0pt, align=center, font=\fontsize{12pt}{12pt}\selectfont ] at ([xshift=1.25in, yshift=0.25in]current page.center) { 苗栗縣\\ 苗栗市 }; \end{tikzpicture} \begin{tikzpicture}[remember picture,overlay] \node[anchor=south west, xshift=0.2in, yshift=0.2in] at (current page.south west) { {\Large 豐富 Fengfu} }; \node[anchor=south east, xshift=-0.2in, yshift=0.2in] at (current page.south east) { {\Large 南勢 Nanshi} }; \end{tikzpicture} \begin{tikzpicture}[remember picture,overlay] \draw[green!60!black, line width=1.2pt] ([yshift=0.65in]current page.south west) -- ([yshift=0.65in]current page.south east); \node[anchor=west, text=green!60!black] at ([yshift=0.78in]current page.south west) {\large $\blacktriangleleft$ 3.9 公里 (km)}; \node[anchor=east, text=green!60!black] at ([yshift=0.78in]current page.south east) {\large 6.6 公里 (km) $\blacktriangleright$}; \end{tikzpicture} \end{document} A better version should be: Source: http://trstour.com/miao-li.htm

The following MCE: \documentclass[french]{article} % \usepackage{fnpct} \usepackage{babel} \pagestyle{empty} \begin{document} Foo\footnote{Bar.}\footnote{Baz.}. \end{document} compiled with current lualatex, typesets the footnotes according to the French typographic rules: Bar. Baz. But, if fnpct is loaded, that's not the case since the footnotes are typeset as follows: ¹Bar. ²Baz. At least with TeX Live 2025, we got the expected result even when fnpct was loaded. Here's what has changed since then: LuaHBTeX 1.22.0 (TL 2025) → 1.24.0 (TL 2026) keyval.sty 2022/05/29 v1.15 → 2026-05-17 v1.15 expl3.sty 2025-10-24 → 2026-05-26 l3backend-luatex.def 2025-10-09 → 2026-02-18 babel.sty 2025/10/22 v25.14 → 2026/06/14 v26.9 french.ldf 2025-08-15 v4.0e → 2026-06-06 v4.1a Do you know how to nowadays retrieve the previous, expected, behavior? Edit With current TL 2026, the result is the same with pdftex and with lualatex but, with TL 2025, the result is the expected one: not with pdflatex with lualatex.
