We packaged a font so it can be reusable in different documents (see below). Is it the right way to do it? Comments welcome. The package is then used by simply adding \usepackage{ourfont}. We tried to look at various font packages but it seems to vary much between implementations... In a document (so without modifying the package), we want to disable ligatures for non-italic, or maybe just disable the Discretionary ones, tbd. Again, what is the right way to do this? This font (legally) comes from Adobe and is split into several .otf files for weight/style/optical sizes, hence the complexity of the loading... This is first way we do this, and fontspec seems to offer many solutions. All comments welcome. Thanks. \NeedsTeXFormat{LaTeX2e} \ProvidesPackage{ourfont}[2026-06-28] \RequirePackage{fontspec} \setmainfont{OurFont}[ NFSSFamily = OurFont, Numbers = {OldStyle,Proportional}, Ligatures = {Common,Discretionary}, UprightFeatures = { Font = *, SizeFeatures = { {Size = -8.9, Font = *-Capt}, {Size = 9.0-14.9, Font = *}, {Size = 15.0-22.9, Font = *-Subh}, {Size = 23.0-, Font = *-Disp}, }, }, ItalicFeatures = { Font = *-It, SizeFeatures = { {Size = -8.9, Font = *-ItCapt}, {Size = 9.0-14.9, Font = *-It}, {Size = 15.0-22.9, Font = *-ItSubh}, {Size = 23.0-, Font = *-ItDisp}, }, }, BoldFeatures = { Font = *-Bd, SizeFeatures = { {Size = -8.9, Font = *-BdCapt}, {Size = 9.0-14.9, Font = *-Bd}, {Size = 15.0-22.9, Font = *-BdSubh}, {Size = 23.0-, Font = *-BdDisp}, }, }, BoldItalicFeatures = { Font = *-BdIt, SizeFeatures = { {Size = -8.9, Font = *-BdItCapt}, {Size = 9.0-14.9, Font = *-BdIt}, {Size = 15.0-22.9, Font = *-BdItSubh}, {Size = 23.0-, Font = *-BdItDisp}, }, }, FontFace = {l}{n}{ Font = *-LtDisp, }, FontFace = {l}{it}{ Font = *-LtItDisp, }, FontFace = {sb}{n}{ Font = *-Smbd, SizeFeatures = { {Size = -8.9, Font = *-SmbdCapt}, {Size = 9.0-14.9, Font = *-Smbd}, {Size = 15.0-22.9, Font = *-SmbdSubh}, {Size = 23.0-, Font = *-SmbdDisp}, }, }, FontFace = {sb}{it}{ Font = *-SmbdIt, SizeFeatures = { {Size = -8.9, Font = *-SmbdItCapt}, {Size = 9.0-14.9, Font = *-SmbdIt}, {Size = 15.0-22.9, Font = *-SmbdItSubh}, {Size = 23.0-, Font = *-SmbdItDisp}, }, }, ] \def\rmdefault{OurFont} \renewcommand{\familydefault}{\rmdefault}

I am trying to draw a line in TikZ between two arbitrary points, for example, from $A(0,0)$ to $B(3,5)$, where the gradient (degradation) runs perpendicularly (transversely) to the path itself. The line should be solid black in the exact center and fade smoothly to white/transparent on both the top and bottom edges, looking like a soft or blurred brush stroke. like this: I managed to approximate this by drawing a manual path with calc offsets and calculating the specific shading angle manually: \begin{tikzpicture} % Define coordinates for the horizontal path (center-line) % A is the starting point, B is the ending point \coordinate (A) at (0,0); \coordinate (B) at (6,0); % Create a vertical degradation (fading) using a shaded rectangle. % We define a rectangle centered on the line, where: % - top color fades to white % - bottom color fades to white % - middle color is solid black % Adjust the height (e.g., 0.6cm) to make the bar and blur thicker or thinner. % Adjust the width (the X coordinate of B) to make it longer or shorter. \shade[top color=white, bottom color=white, middle color=black, line cap=butt] ($(A) + (0, 0.3cm)$) rectangle ($(B) + (0, -0.3cm)$); \end{tikzpicture}

I'm trying to work two parallel columns of text with the multicol package. When I try to break columns it seems to be ignored. Here's a MWE: \documentclass[b6paper, 10pt, twoside, openright, final]{memoir} \setlrmarginsandblock{1.5cm}{.5cm}{*} \setulmarginsandblock{1.5cm}{*}{1} \checkandfixthelayout{} \usepackage{multicol} \usepackage{xcolor} \usepackage{lipsum} \title{ My Memoir } \author{M} \date{June 28, 2026} \begin{document} \begin{multicols}{2} \parbox[t]{\columnwidth}{% \lipsum[1][1-2] } \vfill\ \columnbreak \parbox[t]{\columnwidth}{% \lipsum[2][1-2] } \vfill\ \end{multicols} \end{document} The text continues on the same paragraph without switching columns. How can I make sure the text switches from the left column into the right column?

I want to adjust the table of contents such that The names of \parts are centered in the toc and appear with page numbers and The name of the toc has two lines that are centered. When I center the \parts, and add page numbers, these are not aligned with the page numbers of my sections. How can I align them properly? When using two lines in the name of the toc, the centering does not work.

A user ask to stack diacritics at small capitals in NewCM. Small Capitals are accessible with scmp from lowercase and with c2sc from uppercase. But stacking fails. When say A is followed by U+0304 (combining macron) with c2sc enabled the letter switches to the plain capital A. When U+0304 is removed the A in small capital is produced. NewCM contains information for stacking at its small capitals too but it seems that there is a but in the engine or something else happens which I do not understand. Here is a MWE: \documentclass{article} \usepackage[default]{fontsetup} \begin{document} \addfontfeatures{RawFeature=+c2sc} \textsc{ā, ī, ū, ṭ, ḍ, ḷ, ṁ, ṃ, ṇ, ṅ, ñ} \textsc{a}̄ \textsc{a} A Ā \end{document} Notice that sc n with tilde works because this character is precomposed in the font. But we can not expect the font to have all characters precomposed. This is why we have stacking. The output is erratic. The line \textsc{a}̄ is not a result of stacking but of negative width of the macron, this is why it is not centered. Notice that you may find another font that gives correct output. But this will happen just because it has the above characters precomposed. Stacking still fails. We cannot precompose everything.

I'm trying to draw straight lines in a matrix using nicematrix, and I achived the code: \documentclass{article} \usepackage{nicematrix,tikz} \begin{document} \begin{equation*} \begin{bNiceMatrix} \CodeBefore[create-cell-nodes] \begin{tikzpicture} %\draw[blue,-] (3-1) -- (4-2) ; %\draw[blue,-] (4-2) -- (3-4) ; \draw[blue,-] (3-1.north west) -- (4-2.south east) ; \draw[blue,-] (4-2.south east) -- (3-4.north east) ; \end{tikzpicture} \Body a_{11} & a_{12} & a_{13} & a_{14} \\ a_{21} & a_{22} & a_{23} & a_{24} \\ a_{31} & a_{32} & a_{33} & a_{34} \\ a_{41} & a_{42} & a_{43} & a_{44} \end{bNiceMatrix} \end{equation*} \end{document} My problem is the straight lines are not centered in the entries of the matrix (see image below); I considered also \draw[blue,-] (3-1) -- (4-2) ; \draw[blue,-] (4-2) -- (3-4) ; instead of \draw[blue,-] (3-1.north west) -- (4-2.south east) ; \draw[blue,-] (4-2.south east) -- (3-4.north east) ; but in this case the two line are not linked. Any hint (desirably keeping the matrix created by nicematrix)? Thanks.

I'm trying to make a worksheet where students need to fill out parts of a long division statement. I usually use the longdivision package, but realized that I can't cover up parts of it for students to fill out. Any suggestions? I've attached an image for reference.

I want to create a blood glucose monitoring log with longtblr. The core requirement is: after I input glucose numbers inside table cells, the weekly and monthly statistical results (max value, min value, average value) can be automatically recalculated and updated every time I compile the document. My original code uses static text for statistics, which means I have to rewrite all stats manually every time I add new glucose data. This is inefficient. I hope to use LaTeX built-in calculation packages to extract all valid numbers from table cells and generate statistics automatically.

Every time I add or modify glucose values inside table cells, I have to manually recalculate and rewrite all max/min/average lines, which is tedious and error-prone. I need an automatic calculation mechanism: extract all decimal glucose numbers from specific table columns (Fasting, 1h postprandial, 2h postprandial), filter empty cells out, then compute maximum, minimum and average automatically. The computed weekly and monthly statistics should refresh automatically every time I compile the PDF, without manually editing statistic text blocks. The table uses longtblr for multi-page breaking and colored column backgrounds; please keep the original table layout, coloring and Chinese support (ctex package). Numbers inside cells have time suffix like 6.7(8:56); the parser only needs to extract the float value before the parenthesis and ignore time text. What packages/methods are suitable? Is it possible to use xfp, expl3 or pgfmath to collect numbers from longtblr cells and do batch statistics? If longtblr cannot expose cell contents to global macros, what alternative structure can I adopt to separate raw data storage and table display while retaining auto-statistics?

I would like to write two commands, \bframe and \eframe, so that \bframe Lorem ipsum \eframe is equivalent to \begin{frame} Lorem ipsum \end{frame} However the straightforward solution \newcommand{\bframe}{\begin{frame}} \newcommand{\eframe}{\end{frame}} leads to the error File ended while scanning use of \beamer@collect@@body, which I cannot understand.

I'm trying to do the following in LuaLaTeX: having the main font be Arial; having the upper case letters in math font be Arial (if posible, not a strong requierement); having the lower case letters in math font be latin modern; having the numbers in math font be in Arial. To achieve these goals, I found out that the package mathastext could be a solution (as mentionned in a previous post), if used with the option "noletters". However, this option doesn't work as intended (or maybe I didn't understand what it was meant to do).

I have been working with google AI on this for one hr, the AI even gave up and suggested I try tex stackexchange. I simply want to add caption to an image. Easy, right? but the trick part is that part of the caption is verbatim and in small font.

Here are two trials out of dozen or so and none of them worked. \starttext \placefigure {verview of EJB security concepts. {\tpx ejb\_sec\_1.vsd}}%caption {\externalfigure[dummy][width=0.7\textwidth]} \placefigure {verview of EJB security concepts. {\tpx\type{ejb_sec_1.vsd}}}%caption {\externalfigure[dummy][width=0.7\textwidth]} \stoptext Both give long compile errors. This below works \starttext \placefigure {verview of EJB security concepts. \type{ejb_sec_1.vsd}} {\externalfigure[dummy][width=0.7\textwidth]} \stoptext But I want the text ejb_sec_1.vsd to be in small/tiny font. And this is where google AI could not figure how to do it. It tried to explain to me why this works in Latex something related to immediate macro expansion but in context it is passing things to lua engine and all that. All of it was over my head. Is there a simple way to do this in context? TL 2026 on linux

I have several TikZ pictures. These are a set of rectangles with some nodes inside, creating a grid on a page. These are spaced by \hspace horizontally and \vspace vertically. It mostly works unless \hspace is just after the \vspace. When I want to push a TikZ picture toward right margin after \vspace, \hspace doesn't work. I think it is related to a switch from vertical to horizontal mode, but I haven't mastered it yet. I removed the nodes from TikZ code, but what matters (and does not work) is left intact. \documentclass[a4paper]{article} \usepackage{geometry} \geometry{a4paper,top=10mm,bottom=27mm,hmargin=10.0mm} \usepackage{tikz} \usepackage{graphicx} \pagestyle{empty} \setlength\parindent{0pt} \begin{document} \begin{tikzpicture} \draw[rounded corners=2pt] (0,0) rectangle (60.00mm,60.00mm); \end{tikzpicture}\hspace{5mm} \begin{tikzpicture} \draw[rounded corners=2pt] (0,0) rectangle (60.00mm,60.00mm); \end{tikzpicture}\hspace{5mm} \begin{tikzpicture} \draw[rounded corners=2pt] (0,0) rectangle (60.00mm,60.00mm); \end{tikzpicture}\vspace{5mm} \hspace{65mm}\begin{tikzpicture} \draw[rounded corners=2pt] (0,0) rectangle (60.00mm,60.00mm); \end{tikzpicture}\hspace{5mm} \begin{tikzpicture} \draw[rounded corners=2pt] (0,0) rectangle (60.00mm,60.00mm); \end{tikzpicture}\vspace{5mm} \end{document} Edit: I replaced code snippet with complete document for better clarity.

In the following setup, I have a couple of images that forms part of a very large figure. The float ends up on a page of floats (on its own), because of the size. I plan on drawing some elements in the background, simulated by the background fill being the example images via \AddToHookNext{shipout/background}{<background drawing>}: \documentclass{article} \usepackage{lipsum,tikz} \begin{document} \lipsum[1-2] \begin{figure} \centering \tikz [remember picture] \node [inner sep = 10pt] (image-a) {\includegraphics[width = 0.5\linewidth]{example-image-a}}; \bigskip \tikz [remember picture] \node [inner sep = 10pt] (image-b) {\includegraphics[width = 0.5\linewidth]{example-image-b}}; \bigskip \tikz [remember picture] \node [inner sep = 10pt] (image-c) {\includegraphics[width = 0.5\linewidth]{example-image-c}}; \caption{A large figure} \AddToHookNext{shipout/background}{% \begin{tikzpicture}[remember picture, overlay] \filldraw [draw = red, fill = red!10!white, thick] (image-a.south west) rectangle (image-a.north east); \filldraw [draw = blue, fill = blue!10!white, thick] (image-b.south west) rectangle (image-b.north east); \filldraw [draw = green, fill = green!10!white, thick] (image-c.south west) rectangle (image-c.north east); \end{tikzpicture}} \end{figure} \lipsum[3-10] \end{document} Using this approach, however, puts the background drawing on the page where the original figure is processed, rather than where the actual figure is placed. How can I adjust the code so that the background content is placed correctly on the page where the float ends up? Ideally I'd like to keep the code as part of the figure as it semantically belongs with the figure, rather than placing it at some other bizarre place in the document just to make sure it fits there.

Minipages are so common that I can't believe this hasn't been answered before, however I googled for about an hour and I came up with nothing, so here I am. I noticed that the minipage environment has some sort of default inner padding (about 2.5 mm or 1/10 in), which I would like to remove. How can I do it, using options or another elegant way, without using some odd negative \hspace or something similar? To explain what I'm talking about, I made the MWE below comparing a minipage to a tcolorbox. Se how the tcolorbox of the same declared length of the minipage is shorter due to the absence of padding, and see how a tcolorbox of the same visual length of the minipage is actually 5 mm wider in its declaration. Notice also how the pink minipage with the envelope is narrower than the envelope itself, so the envelope doesn't get properly centred by \centering and it stays within the pink area only thanks to the margin. The left margin can be clearly seen also in the yellow minipage. \documentclass[a4paper,11pt]{article} \usepackage{fontawesome7} \usepackage{xcolor} \usepackage{tcolorbox} \setlength{\parindent}{0pt} \begin{document} \colorbox{lightgray}{ \begin{minipage}{8.6cm} \colorbox{pink}{ \begin{minipage}{2mm}\centering \faEnvelope{} \end{minipage} } \colorbox{yellow}{ \begin{minipage}{7.35cm} lperson@email.org \end{minipage} } \end{minipage} } \vskip 2mm \begin{tcolorbox}[boxsep=0pt,top=4pt,left=0pt,right=0pt,bottom=4pt,arc=0pt,colback=lightgray,frame empty,width=9.1cm] actual minipage width \end{tcolorbox} \vskip 2mm \begin{tcolorbox}[boxsep=0pt,top=0pt,left=0pt,right=0pt,bottom=0pt,arc=0pt,colback=lightgray,frame empty,width=8.6cm] \begin{tcolorbox}[boxsep=0pt,top=0pt,left=0pt,right=0pt,bottom=0pt,arc=0pt,colback=pink,frame empty,width=6mm,,after=\hspace{0mm}]\centering \faEnvelope{} \end{tcolorbox} \begin{tcolorbox}[boxsep=0pt,top=0pt,left=0pt,right=0pt,bottom=0pt,arc=0pt,colback=yellow,frame empty,width=7cm,before=\hspace{0mm}] lperson@email.org \end{tcolorbox} \end{tcolorbox} \end{document} This is the visual result of the code above:

The manual for TikZ-CD has a section called "3.3 Drawing diagrams directly with TikZ" that shows how to use the TikZ-CD styles "outside Tikz-CD". For example, "shift left" and "shift right" are styles defined in tikzlibrarycd.code.tex, and by default they only work inside a \begin{tikzcd}...\end{tikzcd} block; the tricks from section 3.3 should make "shift left" and "shift right" work inside a \begin{tikzpicture}...\end{tikzpicture} block, but the last example below shows that that doesn't work, or at least don't work inside a \draw, with the syntaxes that I've tried...

I want to use a lighter series of a font by default with babel, but I get annoying warnings: LaTeX Font Warning: Font shape `TU/lmr/ul/n' undefined (Font) using `TU/lmr/m/n' instead on input line 7. LaTeX Font Warning: Font shape `TU/lmss/ul/n' undefined (Font) using `TU/lmss/m/n' instead on input line 7. LaTeX Font Warning: Font shape `TU/lmtt/ul/n' undefined (Font) using `TU/lmtt/m/n' instead on input line 7. This code without babel is ok: \documentclass{article} \usepackage{fontspec} \newfontfamily{\notosans}{Noto Sans}[ NFSSFamily = notosans , FontFace = {ul}{n}{Font=Noto Sans Thin} ] \renewcommand*{\familydefault}{notosans} \renewcommand*{\seriesdefault}{ul} \begin{document} zzz \end{document} But this code with babel gives warnings: \documentclass{article} \usepackage{babel} \babelprovide[import, main]{english} \babelfont{notosans}[FontFace = {ul}{n}{Font=Noto Sans Thin}]{Noto Sans} \renewcommand*{\familydefault}{\notosansdefault} \renewcommand*{\seriesdefault}{ul} \begin{document} zzz \end{document} Having to define dummy series for every font seems like it should not be necessary. Is there a way around this?

Clearly I'm missing something basic. I have a token list (expanded, I think) to \foo, that I want to use as an argument to the \SplitList macro, but apparently it is not expanded enough... \documentclass{article} \usepackage[papersize={5.5in,8.5in},margin=0.6in]{geometry} \usepackage{pgffor} \newcounter{expnum} \newtoks\revsett \NewDocumentCommand{\tohsett}{ >{\SplitList{,}}m }{\ProcessList{#1}{\tohsettaux}} \NewDocumentCommand{\tohsettaux}{m}{\stepcounter{expnum}\preit{#1}} \def\preit#1{\edef\bar{\global\revsett={#1,\the\revsett}}\bar}% reverses order \parindent0pt \begin{document} \toks0={1,2,3} \edef\foo{\the\toks0} This does not work, picks up only one argument:\\ \tohsett{\foo}\theexpnum, \the\revsett \revsett={} \setcounter{expnum}{0} This works, finds all three arguments...\\ \tohsett{1,2,3}\theexpnum, \the\revsett \revsett={} ...as does this\\ \foreach \n in \foo {\preit{\n}}\the\revsett \thispagestyle{empty} \end{document} I feel dumb, overlooking something embarrassingly basic...

I am trying to vertically center text in an figure in relation to the graphic inserted in the environment Here is the figure environment code I am using \begin{document} ... \begin{figure}[h] \includegraphics[scale=0.15]{test.jpg} \begin{minipage}[c][\columnsep][c]{1.0\linewidth} \hspace{2em} {\Large \today} \end{minipage} \end{figure} \newpage \includepdf[pages=-]{pdf.pdf} \newpage \end{document} This is the result: I can't entirely tell, but from playing with the position options the height of the figure environment may be different from the height of the images. Also this is a problem I am less worried about but for some reason if the figure goes off the page, it goes to the page after the inserted pdf from \includepdf rather than to the next page.

I have just started using the 3d library in TikZ (and I'm quite new to the tikz package itself). I am modelling a physics problem; I want to draw a sphere that represents my system. The particularity of that sphere is to have regions delimited by parallel circles around the North and South poles; I would like to color these regions in a different shade than the rest of the sphere. I have been looking everywhere and I can't find how to do this (if it is possible); using \path and \fill doesn't seem to work. Sorry if it's a stupid question, thanks for your help! Here is my code (I'm also showing the θ,φ parametrization in my sketch; in commentary, my failed attempts for coloring the North Pole): \documentclass{article} \usepackage{tikz} \usepackage{tikz-3dplot} \usepackage{pgfplots} \begin{document} \begin{tikzpicture}[scale=3,tdplot_main_coords] \def\rvec{1.2} \def\thetavec{55} \def\phivec{35} \def\thetaRC{10} \shadedraw[tdplot_screen_coords,ball color = white] (0,0) circle (\rvec); \coordinate (O) at (0,0,0); \tdplotsetcoord{C}{\rvec}{\thetavec}{\phivec} \tdplotsetcoord{UD}{\rvec}{\thetaRC}{90} \tdplotsetcoord{UG}{\rvec}{\thetaRC}{-90} \draw[thick,->] (0,0,0) -- (1.7,0,0) node[anchor=north east]{$x$}; \draw[thick,->] (0,0,0) -- (0,1.7,0) node[anchor=north west]{$y$}; \draw[thick,->] (0,0,0) -- (0,0,1.7) node[anchor=south]{$z$}; \draw[-stealth,very thick,color=green!60!black] (O) -- (C) node[above right=-2] {P}; \draw[dashed, color=green!60!black] (O) -- (Cxy); \draw[dashed, color=green!60!black] (C) -- (Cxy); \tdplotdrawarc[color=green!40!black]{(O)}{0.4}{0}{\phivec}{anchor=north}{\(\varphi\)} \tdplotsetthetaplanecoords{\phivec} \tdplotdrawarc[color=green!40!black,tdplot_rotated_coords]{(0,0,0)}{0.7}{0}{\thetavec}{anchor=south west}{\(\theta\)} \draw[dashed] (\rvec,0,0) arc (0:360:\rvec); \draw[thick] (\rvec,0,0) arc (0:110:\rvec); \draw[thick] (\rvec,0,0) arc (0:-70:\rvec); %\tdplotdrawarc[fill=green!40!black]{(0,0,.995*\rvec)}{.0998}{0}{360}{anchor=south west}{\(\theta\)}; %\path[fill=red,fill opacity=0.5] (0,0,\rvec) -- plot[variable=\t,domain=0:360] (xyz spherical cs:radius=\rvec,longitude=\t,latitude=90-\thetaRC); \end{tikzpicture} \end{document}
