I'm using the following code to write boxes. I have two problems: If in my box I only put \vspace{..}, the "name" of the box goes at the very end of the box. If in the box I only put an enumerate/itemize environment, the fist bullet goes right after the name of the box. I can a "\ " before the enumerate but then there is a big space between the first item and the name of the box. Is there any way to avoid these two situations? Many thanks! \usepackage{amsthm} \usepackage{thmtools} \declaretheoremstyle[ headfont=\bfseries\sffamily\color{Blue!70!black}, headpunct=\par, postheadspace = \newline, spaceabove=0.2cm, mdframed={ roundcorner=10pt, linewidth=2pt, rightline=false, topline=false, bottomline=false, leftline=true, linecolor=Red, backgroundcolor=Blue!10, nobreak=false } ]{thmbluebox} \declaretheorem[style=thmbluebox, numbered=no, name=Nameofbox]{reso} %%%Problem 1 \begin{reso} \vspace{5cm} \end{reso} %%%Problem 2 \begin{reso} \begin{itemize} \item Hello \item Hello \end{itemize} \end{reso}

The following MCE works nicely. \documentclass{article} \makeatletter % \@ifclassloaded{article}{% \ExplSyntaxOn \AtBeginDocument{\NewCommandCopy\textbf__orig\textbf} \ExplSyntaxOff % }{} \makeatother \begin{document} \end{document} But, if \@ifclassloaded{article} is uncommented, it doesn't work anymore, complaining that: ! LaTeX Error: Command \textbf already defined. Forcing to continue, we are facing: ! Missing $ inserted. which clearly confirms that \ExplSyntaxOn is ignored. Do you understand what's going on?

I’m using the KOMA-script-class scrbook with the postnotes-package. Placing the postnotes and employing the correct \postnotesection turns out to be a bit trickier than I thought. The manual clearly states: »[P]rominently a \postnotesection is skipped at \printpostnotes if it contains no notes. In other words, if two (or more) calls of \postnotesection occur in immediate sequence, with no \postnote in between, the latter call takes precedence over the former, instead of being accumulated in the queue.« (p. 8) Question: Can I force such an entry anyway for the intended position? MWE: \documentclass{scrbook} \usepackage{postnotes} \counterwithin*{postnote}{part} \usepackage{hyperref} \begin{document} \tableofcontents \addpart{First Part} \postnotesection{\addsec{Notes to Part I}} \addchap{First chapter of the First Part} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \addchap{Second chapter of the First Part} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \addpart{Second Part} \postnotesection{\addsec{Notes to Part II}} \addchap{First chapter of the Second Part} \postnotesection{\subsection*{Notes to Chapter II.1}} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \addchap{Second chapter of the Second Part} \postnotesection{\subsection*{Notes to Chapter II.2}} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \addpart{Third Part} \postnotesection{\addsec{Notes to Part III}} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \addchap{First chapter of the Third Part} \postnotesection{\subsection*{Notes to Chapter III.1}} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \addchap{Second chapter of the Third Part} \postnotesection{\subsection*{Notes to Chapter III.2}} Foo.\postnote{Foo note.} Bar.\postnote{Bar note.} \printpostnotes \end{document} Problem 1: »Notes to Part II« is swallowed, as there are no postnotes before the first \addchap comes. See: Problem 2: The necessary entry in the ToC is also swallowed, for the same reason. See: Background to the problem: The book intended shall be divided in three parts. Content-wise, the first part is a long introduction, and the third part is a long afterword with about 100 postnotes each. The second part, however, contains many smaller chapters with separate postnote-numbering. Some of these chapters in the second part don’t contain any postnotes at all, some quite a lot. I would like a reader flicking through the postnotes to receive a clear hint that the chapter-postnotes belong to Part II – which is why I want to force it. The second most important cue (first being the running page numbers in the headers) shall be the section-wise placement in the Toc.

I am using TeXworks to compile a file that is a mixture of Gregorian chant and regular music scores. In order to use the GregorioTeX package, I have to use a modified LuaLaTeX processing tool with the following arguments: --shell-escape $synctexoption $fullname The Gregorian chant works just fine, but my issue occurs when I try to use MusixTeX to include a metered song. The music does not wrap properly, and it looks clunky. Reading through the MusixTeX documentation file here, it appears that I need to use musixflx to fix this issue. However, I have no idea how to do that. I think I need to include it somehow in the processing tool's arguments, but I'm unsure. Is there a way to use musixflx while also running the necessary commands for GregorioTeX? Also, do I need to download anything to use musixflx, or is it part of the MusixTeX package? Here is a sample set of code: % !TEX program = LuaLaTeX+se \documentclass[12pt, twoside]{article} \usepackage[paperheight=8.5in,paperwidth=5.5in,margin=.5in]{geometry} \usepackage{tabularx} \newcolumntype{Y}{>{\raggedleft\let\newline\\\arraybackslash\hspace{0pt}}X} \usepackage[autocompile]{gregoriotex} \usepackage{import} \usepackage{tikz} \usetikzlibrary{tikzmark} \usepackage{fontspec} \setmainfont{Times New Roman} \setlength{\parindent}{0pt} \setlength{\parskip}{6pt} \newenvironment{nscenter} {\par\nopagebreak\centering} {\par\vspace{-6pt}\noindent\ignorespacesafterend} \usepackage{changepage} \usepackage{xcolor} \usepackage{verbatim} \usepackage{amssymb} \usepackage{enumitem} \usepackage{textcomp} \input musixtex \input musixlyr \input musixdbr \setclef{1}{\treble} \nobarnumbers \def\voltadot{} %\grechangedim{spacebeneathtext=2cm} \usepackage{fancyhdr} \fancyhf{} \renewcommand{\headrulewidth}{0pt} \fancyfoot[LE,RO]{\thepage} \pagestyle{fancy} \geometry{footskip=-3pt} \begin{document} \begin{nscenter} \textbf{Sample} \end{nscenter} \textsc{\textcolor{red}{Intro}} \hspace{2em}Below, I would like to include a metered song, rendered in modern musical format.

This is not a MWE at this point but I'd like to first ask if anything may have changed since August 2024 or so that might make this package and command no longer work as they did at that time. I have the PDF document on my desk that the .tex file and LaTeX (using Kile) produced at that time; but, it will not generate again because of errors like main.tex:102:too deeply nested.\begin{quotationnbr} every where quotationnbr is used.

Because I discovered that NewCMMath has a bold version, I set the \bm command in unicode-math. However, whenever I try to use \bm{\symsf{A}} or similar to other \bm{\symxx} fonts, it fails; However, it works for pure letters. \documentclass{article} \usepackage{unicode-math} \setmathfont{NewCMMath-Regular.otf} \setmathfontface{\bm}{NewCMMath-Bold.otf} \begin{document} $\symsf{ABCabc}, \symscr{ABCabc}$\\ with bm command: $\bm{\symsf{ABCabc}, \symscr{ABCabc}}$\\ ideal glyphs: $\symbfsf{ABCabc}, \symbfscr{ABCabc}$ \end{document} \documentclass{article} \usepackage{unicode-math} \setmathfont{NewCMMath-Regular.otf} \setmathfontface{\bm}{NewCMMath-Bold.otf} \begin{document} $\bm{ABCabc123\alpha\beta\gamma}$ \end{document}

Recently, I came across a multiplication table in Visual Group Theory (Fig. 4.6). I tried to reproduce it, including asking AI assistants (ChatGPT, Claude), but without success. It seems that AI struggles to handle the subtle blanks in this table. I believe TikZ could produce something similar, but the result would feel unnatural. Is it possible to construct this in the form of a table? The closest result I've achieved so far is as follows. It uses the package nicematrix . \documentclass{article} \usepackage{nicematrix} \usepackage{tikz} \usepackage{amsmath} \begin{document} \begin{NiceTabular}{c*{4}{c}}[ hvlines, corners = NW, ] & $N$ & $R$ & $B$ & $RB$ \\ $N$ & $N$ & $R$ & $B$ & $RB$ \\ $R$ & $R$ & $N$ & $RB$ & $B$ \\ $B$ & $B$ & $RB$ & $N$ & $R$ \\ $RB$ & $RB$ & $B$ & $R$ & $N$ \\ \end{NiceTabular} \end{document} The book also contains more intricate tables of this kind(same elements have a same color), and I'm curious how those might be reproduced as well.

I am working with ConTeXt LMTX 2026 and trying to customize an itemgroup (or itemize) to display the numbers inside colored circles. I have tried several approaches, including \framed, MetaPost graphics, and \defineconversion with Unicode symbols. However, I am facing consistent issues where either the numbers don't render inside the shapes, or the itemize environment overrides the custom formatting. Here is the basic structure I am currently using that works for standard underlining:

I am currently working on a document that uses both Greek and English. For these two languages, I would like to use two different fonts, namely EB Garamond and GFS Neohellenic. I would also like to use old style numbers. For some reason, I am not able to get both options working. Here's an example of what I mean: \documentclass{article} \usepackage{fontspec} \setmainfont[Numbers=OldStyle,Language=English]{EBGaramond-Regular} \setmainfont[Script=Greek]{GFSNeohellenic-Regular} \usepackage{lipsum} \begin{document} \lipsum[1] \begin{quote} Ἥκω Διὸϲ παῖϲ τήνδε Θηβαίαν χθόνα‎\\ Διόνυϲοϲ‎, ὃν τίκτει ποθ‎' ἡ Κάδμου κόρη‎\\ Ϲεμέλη λοχευθεῖϲ‎' ἀϲτραπηφόρωι πυρί‎·\\ μορφὴν δ‎' ἀμείψαϲ ἐκ θεοῦ βροτηϲίαν‎\\ πάρειμι Δίρκηϲ νάμαθ‎' Ἱϲμηνοῦ θ‎' ὕδωρ‎.\\ (Eur. \textit{Bacch.} 1-5)\end{quote} \end{document} This gives the following output: Then, when I flip the two font options around, this happens: \documentclass{article} \usepackage{fontspec} \setmainfont[Script=Greek]{GFSNeohellenic-Regular} \setmainfont[Numbers=OldStyle,Language=English]{EBGaramond-Regular} \usepackage{lipsum} \begin{document} \lipsum[1] \begin{quote} Ἥκω Διὸϲ παῖϲ τήνδε Θηβαίαν χθόνα‎\\ Διόνυϲοϲ‎, ὃν τίκτει ποθ‎' ἡ Κάδμου κόρη‎\\ Ϲεμέλη λοχευθεῖϲ‎' ἀϲτραπηφόρωι πυρί‎·\\ μορφὴν δ‎' ἀμείψαϲ ἐκ θεοῦ βροτηϲίαν‎\\ πάρειμι Δίρκηϲ νάμαθ‎' Ἱϲμηνοῦ θ‎' ὕδωρ‎.\\ (Eur. \textit{Bacch.} 1-5)\end{quote} \end{document} When I try to use a different font, however, a different problem occurs: \documentclass{article} \usepackage{fontspec} \setmainfont[Numbers=OldStyle,Language=English]{EBGaramond-Regular} \setmainfont[Script=Greek]{New Athena Unicode} \usepackage{lipsum} \begin{document} \lipsum[1] \begin{quote} Ἥκω Διὸϲ παῖϲ τήνδε Θηβαίαν χθόνα‎\\ Διόνυϲοϲ‎, ὃν τίκτει ποθ‎' ἡ Κάδμου κόρη‎\\ Ϲεμέλη λοχευθεῖϲ‎' ἀϲτραπηφόρωι πυρί‎·\\ μορφὴν δ‎' ἀμείψαϲ ἐκ θεοῦ βροτηϲίαν‎\\ πάρειμι Δίρκηϲ νάμαθ‎' Ἱϲμηνοῦ θ‎' ὕδωρ‎.\\ (Eur. \textit{Bacch.} 1-5)\end{quote} \end{document} What happens in the last picture is almost what I would like to happen, except for the fact that the numbers are not in old style and that the Latin font is not EB Garamond... Does anyone know how to fix this?

If this is not possible, perhaps someone could advise an efficient way to do it manually. Before posting this question, I was able to make vertical shifts; however, I was no able to do so horizontally where the entire ISBN and barcode picture moved in unison. I compile with xelatex. Thank you.

First of all, how do we name a boolean variable? I tried \l_myvar_bool by similarity with what i found in an online tutorial. Why do we need \l_? For toggling the variable value i used \bool_set_inverse:N. I think here it's fine. I might have done it right. For printing I used \cs_meaning:N. It prints \char", don't know why. I don't want it. I need a better command. So I'd like to improve this piece of code. \documentclass[a4paper]{article} \setlength{\parindent}{0pt} \ExplSyntaxOn \bool_new:N \l_myvar_bool \NewDocumentCommand{\togglebool}{ }{ \bool_set_inverse:N \l_myvar_bool \cs_meaning:N \l_myvar_bool } \ExplSyntaxOff \begin{document} \togglebool \togglebool \togglebool \end{document}

I am a beginner at using LATEX. I have a question about increasing/decreasing the radius/curve/bulge of the voltage arrow. I am creating a very simple RLC series circuit along with a DC voltage source. I have attached my code below: \begin{circuitikz} \draw (0,0) to [american voltage source, invert, l=$V_s$] (0,6) to [R, l=$R_1$] ++(2.5,0) to [L, l_=$L$] ++(2.5,0) to [C, l=$C$, i=$i_C$, v^<=$v_C$] ++ (0,-6) to [short] ++(-5,0); \draw (2.5,6) to [R, l=$R_2$, *-*] ++(0,-6); \draw (0,0) node[ground, label=west:G] (GND) {}; \end{circuitikz} The output of this code is: As you can see, the text C and the arrow of v_c are sort of overlapping each other. I can easily overcome this issue by bringing the label C to the left or by bringing the voltage arrow to the left. However, I would like to know how I can manipulate the curvature of the arrow itself. I went through the CircuiTikZ User Manual, and questions such as this, this, this, and this but I was unable to solve the issue. I look forward to the opinion of the advanced LATEX users.

I am required to break the links within url{} to my references only after / or //, not after any other symbol that also might occur in a link. As can be seen in this post, this was achieved by adding \def\UrlBigBreaks{\do\/} to my code. Fixing this issue made another problem apparent though, as there would be no line break within certain links but right before them, leaving most of the line blank. How can this problem be resolved? By given guidelines, the list of references is to be formatted left-aligned without hyphenation, yet, links can include a line break after said symbols, thus replacing \raggedright globally by \RaggedRight of \usepackage{ragged2e} unfortunately isn't an option. Setting it locally by wrapping \url{} with \RaggedRight like {\RaggedRight\url{}} seems to make no difference. Potential alternative phrasing for title question: How can I locally allow hyphenation for certain passages in a text that globally doesn't allow hyphenation? Please see the following MWE and its output: \documentclass{article} \usepackage[hidelinks]{hyperref} \def\UrlBigBreaks{\do\/} %\usepackage{ragged2e} \begin{document} { \raggedright %\RaggedRight \begin{thebibliography}{} \bibitem[Smith 2026]{reference} \textsc{Smith}, John (2026) \textit{HMP} : \textit{Hippopotomonstrosesquippedaliophobia} [online].

It looks like the TeX Gyre Pagella font is missing italic parentheses: \documentclass{article} \usepackage{fontspec} \begin{document} \emph{(foo)} \setmainfont{texgyrepagella} \emph{(foo)} (\emph{foo}) \end{document} Am I missing something?

I found this code (bottom of page) which makes the integral sign upright, which I like more than slanted integral sign \usepackage{scalerel} \let\oldint\int \DeclareMathOperator*{\uint}{\scalerel*{\rotatebox{8}{$\textstyle\oldint$}}{\oldint}} \renewcommand{\int}{\uint} I noticed it works on some fonts but not others. Why is that? Is there a way to make either the above code works on all fonts, or a better way to make the integral sign upright for all fonts? Below I give examples where it works and examples where it does not, depending on which font is used. I use only lualatex Here is without adding the code \documentclass[12pt]{article} \usepackage{amsmath} \begin{document} \[ \int \sin x \, dx \] \end{document} When adding the above code to the preamble, here is the output Here is an example when using different font than default it no longer works \documentclass[12pt]{article} \usepackage{amsmath} \usepackage{scalerel} \let\oldint\int \DeclareMathOperator*{\uint}{\scalerel*{\rotatebox{8}{$\textstyle\oldint$}}{\oldint}} \renewcommand{\int}{\uint} \usepackage{unicode-math} \setmainfont{STIX Two Text} \setmathfont{STIX Two Math} \begin{document} \[ \int \sin x \, dx \] \end{document} Here is an example where it worked when trying another font. First without the code \documentclass[12pt]{article} \usepackage{amsmath} \usepackage[T1]{fontenc} \usepackage[math]{anttor} \begin{document} \[ \int \sin x \, dx \] \end{document} When adding the code, it changes OK Is there a better method than the above trick which works for all fonts?

The tip of arrow heads in TikZ usually extends on exactly the specified coordinate, for example in \draw[->] (0,0) -- (1,1);. Is it possible to align the center of the end mark automatically at the specified coordinate? This is useful for plotting piecewise defined functions using * or o as arrow heads such as in https://commons.wikimedia.org/wiki/File:Discontinuity_jump.eps.png. Another way to achieve a similar result is by calculating the coordinates of the points and adding the points manually by \filldraw[fill=white] (1,0.5) circle (0.75pt);. To illustrate what I would like to have: The center of the two circles should be in the middle of the two blue lines of the MWE. It would also be great if we could define certain x-values to set marks at exactly desired points.

I am preparing a Beamer using Overleaf. I would like to have a long block where statements appear as I proceed. Everything except \uncover<4-> seems to work well. I mean that when "Per il principio del massimo modulo..." appears, the block becomes longer. This is the only instance where it occurs. I'll add two screens; the difference is not that easy to catch from them but it is clear from the presentation. Why is this the case? How can I solve this issue?

I want to reduce the line spacing within an item or items. In example 2, \setstretch{1} has a side effect that the vertical space between the first item and its preceding text (2A) is also narrowed (compare with 1A without the command). Strangely, the space between the last item and its following text remains the same (1B and 2B). In other words, \setstretch{1} command affects the space between the first item and its preceding text. Shouldn't it be independent from the line spacing command? (enumitem package manual on page 3 says that the space before the first item depends on \topsep + \parskip [+ \partopsep] which is the same as the space after the last item.) How can I make the two spaces (1A and 2A) same while using \setstretch{1} command? Or, is there any other valid solution for this? (Of course, I know a not-a-beautiful one that I can manually add a space.)

I'm trying to stylize the mathematical fraction in such a way that both the numerator and the denominator will automatically shrink to roughly fit the line height and preferably the digits will be expanded horizontally to occupy more horizontal space. Being away from the TeX for the last 2-3 years I've consulted an AI-assistent first and it suggested using the afrc (Alternative Fractions) and the font Adobe Caslon Pro which it said supported the afrc but that didn't work out and I gave up asking the AI.

I am asked to produce a document where a figure caption is placed above the figure, and left-aligned (even though it is just a one-line caption). By using the subcaption package and the \captionsetup command it works fine when the figure contains only one image. However, when the figure contains several sub-figures, the sub-captions are always left-aligned, like the main caption. I would like to have the main caption left-aligned but the sub-captions (which are very short) centred below each sub-figure. The following MWE illustrates the problem. Figure 1 is the standard. Figures 2 and 3 have the main caption left-aligned as required, but also the sub-captions come out left-aligned. \documentclass{article} \usepackage[document]{ragged2e} % For left-aligned (ragged right) text \usepackage{subcaption} \usepackage{graphicx} \usepackage{lipsum} \begin{document} \lipsum[66] \begin{figure}[h] \caption{Centered caption above figure} \label{fig:f01} \centering \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{1st}\label{subfig:1st}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{2nd}\label{subfig:2nd}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{3rd}\label{subfig:3rd}\end{subfigure} \end{figure} \lipsum[66] \begin{figure}[h] \captionsetup{singlelinecheck=off,justification=raggedright} \caption{Left-aligned caption above left-aligned figure} \label{fig:f02} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{1st}\label{subfig:1stb}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{2nd}\label{subfig:2ndb}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{3rd}\label{subfig:3rdb}\end{subfigure} \end{figure} \lipsum[66] \begin{figure}[h] \captionsetup{singlelinecheck=off,justification=raggedright} \caption{Left-aligned caption above centered figure} \label{fig:f03} \centering \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{1st}\label{subfig:1stc}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{2nd}\label{subfig:2ndc}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{3rd}\label{subfig:3rdc}\end{subfigure} \end{figure} \end{document} Thank you for your suggestions.

What I want to replicate originally is something as below: Now my key point is the arrow of the following style, similar to the single arrow shape in shapes.arrows: \documentclass[tikz,border=5pt]{standalone} \usetikzlibrary{arrows.meta,positioning,shapes.arrows,decorations.markings} \begin{document} \begin{tikzpicture}[ node distance=2cm and 1cm, shrink/.style={shorten >=#1cm,shorten <=#1cm}, myarrow/.style={ shrink=.75,thick,-Stealth, postaction=decorate, decoration={ markings,mark=at position .5 with { \draw[shrink=0,-] (-10pt,-10pt) -- (10pt,10pt); } } }, mysinglearrow/.style={ shape=single arrow,minimum height=1.5cm,inner sep=3pt,draw,line width=1.2pt, } ] \node[draw] (betaII) {AAAAAAAA}; \node[draw] (betaI)[below left=of betaII]{BBBBBBBBB}; \node[draw] (normal)[below right=of betaII]{CCCCCCCCC}; \draw[myarrow] (betaII.west) -- (betaI.north); \draw[myarrow] (normal.north) -- (betaII.east); \draw[myarrow] (betaI) -- (normal); \node[mysinglearrow,rotate=45] at (-1.75,-1.5) {}; \end{tikzpicture} \end{document} However, that is not behave as a "arrow", but a shape.

When \wideoverbar is applied to a wide input, e.g., \wideoverbar{\alpha\alpha}, \wideoverbar{\alpha\alpha\alpha}, the bar is visually very snug up against the input, and this looks correct to me. However, when \wideoverbar is applied to a narrow input like \alpha, the depicted bar is raised significantly. I think \wideoverbar looks significantly better than \bar and \overbar in general, and would like to use it on narrow contents for reasons to do with both aesthetics and consistency. So, I am looking to get the behavior of wide inputs with narrow inputs. As some examples, \wideoverbar{\alpha} is spaced poorly, \wideoverbar{\alpha\alpha} is spaced well, \wideoverbar{\alpha.} is spaced well, but \wideoverbar{\alpha\!.} is spaced poorly. \wideoverbar{..} is spaced poorly, but \wideoverbar{...} is spaced well. Evidently, there is some "switch" on the vertical height of the bar which somehow depends on the width of the contents. I am using Lualatex with Unicode math + Libertinus math, in case that is relevant. For reference, here is a minimized compilable example of what I am working with: % !TEX program = lualatex \documentclass{acmart} \begin{document} $\wideoverbar{\iota}$, $\wideoverbar{\iota\iota}$, $\wideoverbar{\iota\iota\iota}$, $\wideoverbar{\iota\iota\iota\iota}$ \end{document} I find the vertical spacing on the right highly preferable. I had previously posted the question on reddit.

Consider the following example: \DocumentMetadata{% tagging = draft % } \documentclass{article} \begin{document} a \newpage \begin{enumerate} \item b \end{enumerate} c \end{document} If I compile this document using latexmk with no .aux file, I get the following error: ! Package tagpdf Error: there is no open structure on the stack Type <return> to continue. ... l.16 ? Notes: Line 16 appears to be the blank line between \end{enumerate} and c. With tagging = on or tagging = off it compiles fine, but tagging = draft yields an error. Using lualatex <filename> directly instead of latexkmk -lualatex <filename> it compiles fine. If there is an .aux file left over from a previous run (like if I run once using tagging=on and then switch to tagging=draft, or if I run once using lualatex and then switch to latexmk -lualatex) it compiles fine. (Using Tex Live, updated as of May 28, 2026, in Windows 11 Enterprise.) Questions: Is this expected behavior? If not, should a report be filed? If so, where? (To latexmk, or the tagging project, or both, or somewhere else?) Work-arounds in case anyone else ever encounters this issue: Evidently there are many ways to avoid it (see items 2, 3, 4 above).
