I do not manage to use Archivo as the sans font while using ... practically any other serif font. In the MWEs below, I simply used tgpagella. What should one do? Or did I overlook/misunderstand something?

If needed, the .otf above could be tested.

I'm using the code below. I only want urlcolor=blue and citecolor=violet (and maybe some reference colors to equations blue). With hypersetup active, the table of contents becomes red (despite of having written linktoc=none), and also the title, section and subsections in the black-blue field turn red.

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.

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.

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\printbibtabular \end{document} The title ("Higher-Dimensional Algebra V: 2-Groups") is shown, although it should have been replaced by "banana".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.

I installed Context separately. Then I upgraded to texlive 2026. I encountered a lot of problems: fonts and fonts scripts not being recognised, and so many other issues. How do I properly remove Context from texlive 2026?

I've been trying to figure out why I keep getting a space at the beginning of this equation in this coloured box, but don't know how to remove this consistently for all instances I've written this. It seems to be fine for most expressions I write, and if I remove the multiplicative terms after \left( ... \right), it seems to be fine. I've been using \vspace to the times when this happens, but would rather a different option than a case-by-case solution. \documentclass{article} \usepackage{amsfonts,amsmath,amssymb,amsthm} \usepackage[most]{tcolorbox} \begin{document} \newenvironment{mathscolourbox*}[1]{ \begin{tcolorbox}[ colback=#1!10!white, colframe=#1!10!white, top=0pt, bottom=2pt, ams equation*] }% { \end{tcolorbox}} \begin{mathscolourbox*}{cyan} ds^2 = -\left(1-\frac{2GM}{c^2r}\right) c^2 dt^2 + {\left(1-\frac{2GM}{c^2r}\right)}^{-1}dr^2 + r^2\left(d\theta^2+\sin^2\theta \, d\phi^2\right) \end{mathscolourbox*} \begin{mathscolourbox*}{cyan} ds^2 = -\left(1-\frac{2GM}{c^2r}\right) + \left(1-\frac{2GM}{c^2r}\right) + r^2\left(d\theta^2+\sin^2\theta \, d\phi^2\right) \end{mathscolourbox*} \end{document}

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? So in the below MWE, the contents ought to show: An Unnumbered Chapter Chapter Prefix 1 A Numbered Chapter MWE %! TeX Program = lualatex \DocumentMetadata { , lang = en , pdfstandard = ua-2 , tagging = on , tagging-setup = { math/mathml/luamml/load = false } } \documentclass{report} \EditInstance{heading}{chapter} { prefix = Chapter Prefix } \begin{document} \tableofcontents \addcontentsline{toc}{chapter}{An Unnumbered Chapter} \chapter{A Numbered Chapter} \end{document}

I cloned the repository https://gitlab.lisn.upsaclay.fr/texlive/metapost/ and try to compile the file source\texk\web2c\mplibdir\mp.w with cweave like this: $ pwd /metapost/source/texk/web2c/mplibdir $ cweave mp.w $ pdftex mp.tex I got a error message: ! Missing $ inserted. <inserted text> $ <to be read again> _ <argument> \#define MPOST_ DEBUG_ENVELOPE \C #1->\5\5\quad $/\ast \,${\cmntfont #1 }$\,\ast /$ l.158 \M{5}\B\C{\#define MPOST_DEBUG_ENVELOPE } \6 Curiously there is no \M{5}\B\C on the line 158 in the file mp.tex. My question is: how can I compile the file mp.w correctly to a PDF file?

Why doesn't my output \LaTeX fully translate into \mathcal? \documentclass{article} \begin{document} $\mathcal{\LaTeX}$ \end{document} The following errors also occurred: You can't use `\spacefactor' in math mode. \@->\spacefactor \@m {} l.5 $\mathcal{\LaTeX} $ Sorry, but I'm not programmed to handle this case; I'll just pretend that you didn't ask for it. If you're in the wrong mode, you might be able to return to the right one by typing `I}' or `I$' or `I\par'. Missing character: There is no � in font cmex10!

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

Have you noticed that when using negative spacing to overlap mathematical symbols, after typing a few more words, the other mathematicals text also appears to recede into negative spacing? \documentclass{article} \usepackage{newunicodechar} \newunicodechar{⬲}{\longleftarrow\!\!\!\!\!\!\!\!\oplus} \newunicodechar{⟴}{\longrightarrow\!\!\!\!\!\!\!\!\!\oplus} \begin{document} $A ⬲ B ⟴ C$ \end{document}

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.

I fail to modify the following working code to change the printing of ** into %%. How can I do that? I fear that the answer is easy... Don't judge me, please. 🙂 % !TEX TS-program = lualatex \documentclass[varwidth, border = 3pt]{standalone} \usepackage{verbatim} \begin{document} \directlua{ local test = { "1", "**", "\\three", "++++" } tex.print("\\begin{verbatim}") for i, x in ipairs(test) do tex.print("[" .. i ..

I want to reproduce a cannon considering in old style (one of these) considering that I have not seen a specific symbol. Does anyone know if there’s a symbol that resembles one of this image? I have not found anything.

Is there a possibility to only make the hyperref links to figures blue? \documentclass[a4paper,10pt]{article} \usepackage{hyperref} \hypersetup{ colorlinks = true, linkcolor = blue } \usepackage[style=numeric, defernumbers, backend=biber]{biblatex} \addbibresource{sources.bib} \begin{document} \tableofcontents \section{Section 1} Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \subsection{Subsection 1} Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.\\\\ You can now see \hyperref[f1]{Figure 1} \begin{figure}[h] \caption{This is a triangle} \label{f1} \end{figure} \nocite{*} \printbibliography \end{document} and only Figure 1, Figure 2 shall be printed in blue. However, in this case, also the table of contents is printed in blue and - I'm wondering why - the link in the bibliography is printed in pink? How can I make pink to "normal" here?
