I am developing a document in ConTeXt and I would like to create custom, decorative page numbers using MetaPost. My goal is to design intricate graphics (e.g., shapes or frames) that incorporate the current page number, and to apply this design automatically as the page number in the footer or header of my document. Could you please guide me on: How to define a MetaPost graphic that acts as a page number in ConTeXt? How to pass the current \currentpage value to a MetaPost buffer or a standalone MetaPost module within the header/footer setup? What is the recommended approach in ConTeXt to handle this synchronization between the page counter and the MetaPost rendering? I am working with LMTX/MkIV. Any advice or a minimal working example would be highly appreciated. Thanks in advance!

Can this code be fixed so I can choose between answers and solutions? It also produces blank pages (that don't go away when I remove newpage command after Qs and As). \newcounter{sheetnumber} \newenvironment{problemsheet}{ \stepcounter{sheetnumber} \bigskip \centerline{\bf \Large \ifQ {Sheet} \else \ifA {Answers for sheet} \fi \fi \arabic{sheetnumber}: \ \sheetname} \addcontentsline{toc}{section}{ \ifQ {Sheet} \else \ifA {Answers for sheet} \fi \fi \arabic{sheetnumber}: \ \sheetname} %% Number questions as sheetnumber.questionnumber eg 1.1, 1.2, ... \begin{enumerate}[label=\arabic{sheetnumber}.\arabic*.] %% Uncomment lines below to continue question numbering across sheets % \ifnum\value{sheetnumber}=1 % % First sheet - start numbering questions from 1 % \begin{enumerate}[series=questions] % \else % % Subsequent sheet - continue numbering questions from previous sheet % \begin{enumerate}[resume=questions] % \fi }{\end{enumerate}\ifQ \newpage \else \ifA \newpage \fi \fi} \long\def\ignore#1\endignore{} \long\def\ignoreQ#1\endquestion{\fi} \long\def\ignoreS#1\endsolution{\fi} \long\def\ignoreA#1\endanswer{\fi} \long\def\ignoreT#1\par{\fi} \def\beginquestion#1{\ifQ\item {\sl #1.}\else\ignoreQ\fi} \def\endquestion{\par\goodbreak} \def\beginsolution{\ifS\ifQ\addtocounter{enumi}{-1}\else\fi\item {\sl Solution.\/\ }\else\ignoreS\fi} \def\endsolution{\goodbreak} \def\beginanswer{\ifA{{ \ifQ \addtocounter{enumi}{-1} %\else \ifS \addtocounter{enumi}{-1} \fi\fi} \item {\sl Answer:\/\ } \else \ifS \addtocounter{enumi}{-1} \fi\fi} \item {\noindent } } \else \ignoreA \fi} \def\endanswer{} \newcommand{\textfixed}[1]{\ifT \item[#1] \else\ignoreT\fi} \newcommand{\arrowvec}[1]{\ensuremath{\overrightarrow{\mathrm{#1}}}} %%%%%% ************

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 need to create a flowchart of my dissertation and it seems the forest package suits well. Though, I manage to go down the first fork, I cannot create in the same loop the inverted v. There is no math in this tree, only text. Can someone please help?

TLDR: I would like to output dates thus: 2026 Jun 02 Tue I am aware that there are inbuilt date and time formats in datetime2. There is also very comprehensive documentation — but I don't have time to read it, let alone digest it. From looking at answers to other similar questions, it's very complicated. I modified the answer here to: \number##1 \DTMenglishshortmonthname{##2} \DTMenglishordinal{##3} but now there's no space after the year. In datetime2 v1.5.7: date and time formats, there is \DTMdisplaydate{〈year 〉}{〈month 〉}{〈day 〉}{〈dow 〉}, showing how to input a day of week (dow), but I can't find how to output a calculated day of week. In the example above there are formats like \DTMenglishordinal. But how can I know what various options there are for these? How would I guess that there even was an option called 'English short ordinal'? Has anyone written an article with many examples?

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'm creating a large complex scrbook document, ~65,000 words and over 90 images and chapters - single page chapters with title, image and short text, plus extensive endnotes (postnote), references and index. The Latex code, packages, etc is split between several files and folders, each chapter in a separate file and images in a single folder. All the text has been imported and half the images. Even in draft mode - \usepackage[draft]{scrbook} - it takes about 35 seconds to render. Unchecking 'automatically load included files' makes almost no difference. I have ADHD so make lots of typos only spotted by running 'build & view'. At this stage I only want to check for errors as I go. Any suggestions to speed things up?

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.

I've noticed that when I say "this is code," in KaTeX it fails to display correctly. Is there a way to make it display in a lower-level format? I'm using the KaTeX of official online version. If the Sans serif Bold italic is usable, I hope it can be applied to NewCMSans10-BoldOblique.otf.

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 use xetex to create pdf documents out of LaTeX files. In the interest of general accessibility I would like the pdf file to contain some meta information about the file like the title or the language of the document. This is fairly similar to this question but this is from 2011. Additionally I don't want to manually set the title or the language for the pdf metadata, the LaTeX document already knows what the title is (specified by \title) and what language the document is written in (specified by \setdefaultlanguage) so the pdf meta information should just take this information from the LaTeX directly. The linked question has a way to do this for the title but that was written in 2016 and the comments below show that this feature was already being discontinued back then. So how can I tell xetex to fill as much meta information of the pdf document with the meta information the LaTeX document already has?

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? 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].

I am using \includegraphics{photo.jpg} to upload a photo in a 10% gray background. For 10% gray background INSIDE border \fill[gray!10] ($(current page.north west) + (1cm,-1cm)$) rectangle ($(current page.south east) + (-1cm,1cm)$); To upload the photo (with white background, I used \node at ($(current page.south)+( 6cm,5.2cm)$) { \includegraphics{sig_digital.jpg} }; This produced the following photo: We can see the background is not matching, the photo has white background. I have one option, I can make the background to be white. But I want to keep the background gray while adjust the photo background.

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'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.
