The following code raises an error \documentclass[tikz,border=2mm]{standalone} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture} \def\radius{3} \def\smallr{0.3} \def\angleof#1{#1*360/18+3*360/18} \foreach \i in {0,...,17} { \draw ( \angleof{\i}:\radius ) circle (\smallr); } \foreach \i/\labl/\pos in { 1/$1$/center, 2/$2$/center, 3/$3=d$/east, 4/$4$/center, 6/$6=2d$/east, 9/$9=3d$/east, 12/$12=4d$/west, 15/$15=5d$/west, 18/$18=6d$/west } { \node[anchor=\pos] at ({\angleof{\i}}:\radius+\smallr+.25) {\labl}; } \end{tikzpicture} \end{document} The problem is with the second \foreach loop. But the error message is confusing, Package PGF Math Error: Unknown function `west' (in 'west '). I don't see why west would be used as a "function" in any way. What is the correct way of assigning different anchor points in the iteration?

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?

I have tried to manually do this without complete success. I am using here the GS1 package and am using \EANBarcode. (I did not have so much trouble doing this with the pst-barcode package, though I did have other difficulties to contend with.) QUESTION: How may I, if possible, automatically specify that the ISBN and barcode be placed in the lower right-hand corner location from the onset? 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}

Why do I want to create a new mapping for unicode-math? I noticed that Unicode has sans-serif arrow keys in U+1F850 - U+1F859 range, but unicode-math and \symsf seem to only superficially include them. Also, I noticed that the NewCMMath font has additional sans-serif non-bold Greek characters, but it's not being recognized. Is it possible to create a new mapping in \symsf? \documentclass{article} \usepackage{unicode-math} \setmathfont{NewCMMath-Book.otf} \begin{document} Expected glyphs: $\symbol{"E002}\symbol{"E003}\symbol{"E007}\symbol{"E018}\symbol{"E019}\symbol{"E01A}\symbol{"1F850}\symbol{"1F851}\symbol{"1F852}\symbol{"1F853}\symbol{"E043}\symbol{"E044}\symbol{"E048}\symbol{"E059}\symbol{"E05A}\symbol{"E05B}$\\ Actual glyphs: $\symsf{\Gamma\Delta\Theta\alpha\beta\gamma\leftarrow\uparrow\rightarrow\downarrow}\symsfit{\Gamma\Delta\Theta\alpha\beta\gamma}$ \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?

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?

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 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).

I'm having trouble with the nomenclature not showing up when all content enters via an \include statement. It seems the nomenclature cannot be compiled independently, but needs some content before it. A minimal not working example is: % main.tex \documentclass{article} \usepackage{nomencl} \makenomenclature \begin{document} % content \include{content} % nomenclature \nomenclature{\(c\)}{Speed of light in a vacuum} \nomenclature{\(h\)}{Planck constant} \printnomenclature \end{document} where content.tex is file with just the word 'test': % content.tex test A minimal working example would be exchanging \include{content} with test. How can I have my nomenclature show up and neatly separate all preceding sections with \include without having to add extraneous content?

I am using the "related entries" feature of Biblatex to cross-reference and show relationships among the publications in my Biblatex + Biber bibliography. The bibliography uses the default numeric citation style (e.g., "[1]"). For some reason, the citations generated by my related:... macros have extraneous space between the opening square bracket and the first digit of the citation key. Consider the following minimal example: \documentclass{article} \usepackage{biblatex} \begin{filecontents}{test.bib} @article{eger2025transforming, author = {John Eger}, title = {Transforming Science}, journal = {Journal of Foo}, year = 2025, volume = 1, related = {eger2026transforming}, relatedtype = {later}, } @article{eger2026transforming, author = {John Eger}, title = {Transforming Science}, journal = {Journal of Bar}, year = 2026, volume = 1, } \end{filecontents} \NewBibliographyString{later} \DefineBibliographyStrings{english}{later = {Later published as }} \newbibmacro*{related:later}[1]{% \entrydata{#1}{\autocite{\thefield{clonesourcekey}}}} \addbibresource{test.bib} \begin{document} \nocite{eger2025transforming,eger2026transforming} \printbibliography \end{document} The first entry in the bibliography is rendered as [1] John Eger. “Transforming Science”. In: Journal of Foo 1 (2025). Later published as [ 2]. rather than as [1] John Eger. “Transforming Science”. In: Journal of Foo 1 (2025). Later published as [2]. I can't see anything in my related:later macro that would be causing this extra space. Is this a bug in Biblatex or some problem with my code?
