I want to merge columns using the side-by-side rule in tcolorbox. How can I create something like the image below using tcolorbox? | contents -1 | figure | | contents -2 |

Is it possible to test within a before option command whether or not the item to be written is at the top of the page? For example, I tried in \setuphead before={\doiftopofpageelse{...true...}{...false...}} and it is always true even when the head item is not being written at the top of the page. Thank you. For example, every seciton below show "top of the page". Why? \setuplayout[height=4.7in,width=4in] \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, before={\blank[0mm]}, beforesection={\doiftopofpageelse{\hrule{top of page}}{\hrule{not top of page}}}, after={\blank[5mm,]}, style={\tfa\it}, ] \starttext \showframe \startsection[title={Title One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two}] \input{ward} \stopsection \startsection[title={Title Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext

Not sure if this is the correct way to write things in French, but I usually prefer format like pp.~1--10 for page ranges. Based on the solutions to this question on pp. and this question on dash, now I have the following configuration: \DefineBibliographyStrings{french}{% pages = {pp\adddot}, } \DefineBibliographyExtras{french}{% \protected\def\bibrangedash{% --\penalty\hyphenpenalty}} which seems to work as expected. May I ask if it is indeed the "right" way to achieve this nowadays? Below is a MWE: \documentclass{article} \usepackage[french]{babel} \usepackage{biblatex} \usepackage{filecontents} \begin{filecontents}{\jobname.bib} @article{dash, author = {Dashing, Walter Very}, year = {1942}, title = {Dashing Past a Hyphen}, journaltitle = {Life}, volume = {42}, number = {42}, pages = {123--321}, } \end{filecontents} \addbibresource{\jobname.bib} \DefineBibliographyStrings{french}{% pages = {pp\adddot}, } \DefineBibliographyExtras{french}{% \protected\def\bibrangedash{% --\penalty\hyphenpenalty}} \begin{document} \cite[142--242]{dash}. \printbibliography \end{document}

I am writing a website using WordPress with MathJax. In my LaTeX documents, I use TikZ to construct equations that include graphics embedded in the math (for example, superscripts or subscripts connected by lines drawn with TikZ). I would like to display equations of this kind on my website as well. An example of the desired output is shown in the image below. While this works fine in LaTeX, I do not know how to achieve a similar result on a website using MathJax (or related tools such as tikzjax). Is this possible in principle? If so, what would be the recommended approach? Any help or pointers would be greatly appreciated. The following code produces the equation shown in the image in a LaTeX environment using TikZ. \documentclass[a4paper,15pt,riqno]{bxjsreport}%{bxjsarticle} \usepackage[ipa]{zxjafont} \usepackage{tikz-cd} \usetikzlibrary{calc} \usepackage{amsmath} \usetikzlibrary{tikzmark} \begin{document} \begin{align} a^{\tikzmarknode{X}{x}} +b^{\tikzmarknode{Y}{y}} =c^{\tikzmarknode{Z}{z}} \end{align} \tikz[remember picture,overlay]{ \coordinate (Xp) at ($(X.north)+(0,0.3ex)$); \coordinate (Yp) at ($(Y.north)+(0,0.3ex)$); \coordinate (Zp) at ($(Z.north)+(0,0.3ex)$); \path let \p1 = (Xp), \p2 = (Yp), \p3 = (Zp) in coordinate (TopX) at (\x1,{max(\y1,\y2,\y3)+2ex}) coordinate (TopY) at (\x2,{max(\y1,\y2,\y3)+2ex}) coordinate (TopZ) at (\x3,{max(\y1,\y2,\y3)+2ex}); \draw (Xp) -- (TopX); \draw (Yp) -- (TopY); \draw (Zp) -- (TopZ); \draw (TopX) -- (TopY) -- (TopZ); } \begin{align} d_{\tikzmarknode{X}{p}} +e_{\tikzmarknode{Y}{q}} =f_{\tikzmarknode{Z}{r}} \end{align} \tikz[remember picture,overlay]{ \coordinate (Xp) at ($(X.south)+(0,-0.3ex)$); \coordinate (Yp) at ($(Y.south)+(0,-0.3ex)$); \coordinate (Zp) at ($(Z.south)+(0,-0.3ex)$); \path let \p1 = (Xp), \p2 = (Yp), \p3 = (Zp) in coordinate (BottomX) at (\x1,{min(\y1,\y2,\y3)-2ex}) coordinate (BottomY) at (\x2,{min(\y1,\y2,\y3)-2ex}) coordinate (BottomZ) at (\x3,{min(\y1,\y2,\y3)-2ex}); \draw (Xp) -- (BottomX); \draw (Yp) -- (BottomY); \draw (Zp) -- (BottomZ); \draw (BottomX) -- (BottomY) -- (BottomZ); } \end{document}

How can the blank space above \SectionTitle III be forced at the top of page 2 as it is on the top of page 1? I've tried using \blank[5mm,force] directly but with no change. Am I mis-using the \define command or \definedelimitedtext? I'm just trying to declare this command because it needs to be used many, many times in this document (and it is not a "real" section linked to headers or the TOC). It works, as is, when there is a pagebreak but not when the text flows such that the title starts at the top of a new page. Thank you. \setuplayout[height=4.5in,width=4in] \definedelimitedtext[ST][ spacebefore={5mm,force,fixed}, spaceafter=5mm, ] \define[1]\SectionTitle{% \startST \startalignment[middle] \tfa\it#1 \stopalignment \stopST} \starttext \showframe \SectionTitle{I. Title One} A paragraph of the to fill the line to observe the spacing. \SectionTitle{II. Title Two} \input {ward} \SectionTitle{III. Title Three} A paragraph of the to fill the line to observe the spacing. \SectionTitle{IV. Title Four} Paragraph. \stoptext Added In looking at this further, perhaps the space is being added but the distance is being counted from the end of the previous paragraph and not the top of the page; because the previous page does not reach the bottom since the last paragraph ends one line before the last possible print line. Something that appears closely related and confusing to me is that if change the body to \starttext \showframe \SectionTitle{I. Title One} A paragraph of the to fill the line to observe the spacing. \SectionTitle{II. Title Two} \input{ward} A new line of text to fill the space to reach the very last line. A new paragraph. \SectionTitle{III. Title Three} \stoptext the result is as expected below But, if remove the short "A new paragraph" just before section III, the result is as below; and what confuses me is why the last two lines of the last paragraph of page 1 are now moved to page 2. The same occurs if use \blank[5mm, force] \midaligned{III. Title Three} \blank[5mm] in that, once try to force the space at the top, the two lines of the previous paragraph move also. Is it possible to "separate" the before space from the previous paragraph? Thank you. Also, if, instead of trying to define a command to style a title that isn't a section in any real way, it is defined as a section or subsection that can be excluded from the TOC and headers, then all works as expected. For example, \setuplayout[height=4.5in,width=4in] \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, before={\blank[5mm,force]}, after={\blank[5mm]}, style={\tfa\it}, ] \starttext \showframe \startsection[title={Title One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two}] {\input{ward} A new line of text to fill the space to reach the very last line.} \stopsection \startsection[title={Title Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Four}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext renders This is what I expected would happen for my attempt at defining \SectionTitle command.

I'm compiling a 25-chapter book using XeLaTeX and memoir in (for my first time) twocolumn mode. Each chapter is a separate file loaded via \include{}. Individual chapters compile correctly with \includeonly{}, but compiling the full book produces errors and layout failures that don't appear in either single-chapter or single-column mode. Specific symptoms: \enlargethispage throws "page is already too large" at locations where it works fine in single-chapter compilation \input of a file containing a float environment triggers "not in outer par mode," but pasting the same content inline works Float placement (figure*, table*, strip from cuted) becomes unpredictable — floats migrate to wrong pages with no obvious cause and can't be forced back without abandoning the float environment altogether. Environment: XeLaTeX + memoir class cuted package for strip environment placeins, dblfloatfix, float, afterpage, longtable, mdframed, tcolorbox, rotating, nowidow multicol (for one specific 3-column text block) What I've tried: Removing \enlargethispage at problem locations (works around the error but doesn't explain it) Replacing \input with literal content (works, but defeats the purpose) Adjusting float placement specifiers (inconsistent results) My question: For those who have successfully produced print-ready books in two-column memoir: what combination of packages, settings, and workflow practices gives you deterministic results with full-width floats? I'm less interested in debugging my specific errors than in learning whether there's a more robust foundation I should be building on.

I tried all answers in Spacing around \left and \right and none of them work. I use code generate by computer CAS. And all the code generates \left(...\right). So not possible to do any manual editing of latex code generated. Only issue is that something like f\left(x\right) adds extra space between function name f and the parentheses. I am not talking about any space inside parentheses, but the space outside between function name and starting (. I only want this space to be the same as if code was written using f(x). Nothing else change. First, here is MWE showing the issue \documentclass[12pt]{article} \usepackage[T1]{fontenc} \usepackage{kpfonts,baskervald} \usepackage{amsmath} \begin{document} \begin{align*} \int \frac{dy}{g(y)} &= \int f(x) \, dx\\ \int \frac{dy}{g\left(y\right)} &= \int f\left(x\right) \, dx \end{align*} \end{document} Compiled with lualatex gives Notice how the space after function name is larger when using \left(...\right) which is the second equation. I'd like the space after function names and starting ( in the second equation to be same as first equation as it looks better. Below are all my tries. Some of them fix the space after g and not after f and some solution fix the space after f but not after g. But there is no solution which produce same exact output for second equation as the first one. Try 1 (accepted answer in the above link) \documentclass[12pt]{article} \let\originalleft\left \let\originalright\right \renewcommand{\left}{\mathopen{}\mathclose\bgroup\originalleft} \renewcommand{\right}{\aftergroup\egroup\originalright} \usepackage[T1]{fontenc} \usepackage{kpfonts,baskervald} \usepackage{amsmath} \begin{document} \begin{align*} \int \frac{dy}{g(y)} &= \int f(x) \, dx\\ \int \frac{dy}{g\left(y\right)} &= \int f\left(x\right) \, dx \end{align*} \end{document} Gives Notice the space after g in second equation have become too small.

I want to use siunitx for alignments within a currency table. Perhaps euros are not a scientific unit - but I haven't seen why this might be a problem. I want to use a different font. Anyway there seems to be a strange mixture which leads to a weird result. \documentclass[12pt]{article} \usepackage[margin=2.5cm]{geometry} \usepackage{fontspec} \setmainfont{Bitter}[Ligatures=TeX,Scale=MatchLowercase] \usepackage{tabularx, multirow} \usepackage[locale = DE]{siunitx} \begin{document} \begin{tabular}{S} \textbf{Betrag} \\ 120,00 €\\ -12,00 €\\ \large\textbf{108,00 €}\\ \end{tabular} \end{document} Only the header and the last line are in "Bitter" font. Addtionally I don't understand why the euro sign has an extra space in the 3rd line. The result of the given MWE has two weird aspects: The ammount 120€ and -12€ are NOT in the main font. Is there a way to keep it? the euro sign after -12 has a strange additional space. Is there a way to correct it? (to have only ONE extra space)?

I’m relatively new at diagram drawing in latex. How would I go about drawing an upper half sphere with an elliptic curve plotted along it (to resemble the real projective plane)? I want it to look something like this where you have the upper-half sphere drawn and shaded in a solid light grey, and the intersection of the equation X^3-3XZ^2+3Z^3-Y^2Z=0 with the upper-half sphere, the point (0,1,0) annotated with infinity, and the viewing angle rotated as in the image (and possibly the curve in another colour). I really don’t like the usual 3D look but prefer the way the following attached images look. I’d greatly appreciate your help!

Lately I have been using ltex (in VS Code) quite a lot for spell checking my LaTeX files. One question I have is: is it possible to configure it to behave better with beamer overlay specifications. For instance: when I write \uncover<.(1)->{text} currently, I get a warning Do you wish to insert an arrow? But clearly, this is not intended inside an overlay specification <>. Is it possible to disable warnings specifically inside such specifications? (adding "\\uncover<>": "ignore", to my "ltex.latex.commands": does not help. I guess it does not understand the <> delimiters. (see also a similar question I asked about chktex Chktex: disable warnings on beamer overlay specifications)

The fontsetup package provides with a \convolution operator command to access a big star symbol from the New Computer Modern fonts. However, fontsetup works only with XeLaTeX and LuaLaTeX. How does one access this glyph from the NewCM fonts with ConTeXt? The \convolution command is defined in fspdefault.tex as \DeclareMathOperator*{\convolution}{\mathchoice{\char"E037}{\char"E036}{\char"E038}{\char"E039}}.

How can I display the intersection of the following two surfaces in LaTeX? I have used the following codes as a default but I am not getting acceptable output. Is it possible to create a form to find its intersection points in LaTeX? Thanks a lot. \documentclass[border=3.14mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.16} \begin{document} \begin{tikzpicture} \begin{axis}[domain=0.01:30,xlabel=$x$] \addplot3[surf,domain={0:1},color=green]{x^3+y^3}; \addplot3[surf,domain={0:1},color=red]{(x*(1-y^2)^(.5)+y*(1-x^2)^(.5))^3}; \end{axis} \end{tikzpicture} \end{document}

Lately I have been using chktex quite a lot for ensuring consistency of my LaTeX files. One question I have is: is it possible to configure it to behave better with beamer overlay specifications. For instance: when I write \visible<.(1)>{text} currently, I get a warning 36. You should put a space in front of parenthesis But clearly, this is not intended inside an overlay specification <>. Is it possible to disable warnings specifically inside such specifications (without disabling this warning in the entire file or on a line-based basis)?

How can I read out numbers from a list, say \def\pList{0.1, 1/6, 0.25, 0.4} (or array, say \def\pListArray{{\pList}}), with xint? Background: I want to keep fractions, like 1/6 in it's original form (not decimal value 0.1666 here). On the other hand, I need to calc 1-<value> too, and I want, in the case of 1/6 the value 5/6 (=1 - 1/6). I have a main document with a lot of xint content and calculations; therefore, for consistency reasons, it should be done with xint (it's clear that there are other packages or methods for this); and: There must be a method in the xint-package that I can't find in the manual. Does anybody know? \documentclass[margin=5pt, varwidth]{standalone} \usepackage{tikz} \usepackage{xintexpr} \begin{document} \def\pList{0.1, 1/6, 0.25, 0.4}% List \def\pListArray{{\pList}} \section{The pList} \pList \section{pgfmath-test for fraction-readout (bad)} p=\pgfmathprint{\pListArray[0]}, q=\pgfmathprint{1-\pListArray[0]} good.

I'm considering buying a laptop with the Snapdragon X/X+ chip (such as Dell Inspiron 5441 or HP Omnibook 5). I believe the OS will be Windows 11 ARM. I heard of compatibility issues with certain apps and games, so I am asking to double check : Will I be able to install MikTex and work with Texniccenter as usual ? I know I can work on overleaf, but it's important for me to be able to work offline. Thanks very much !

\bmod seems to behave differently in text style and script style (here is just an example, in reality I am writing it on the arrow of a commutative diagram). Am I using this command in a wrong way? (I learned \bmod from here.) \documentclass{article} \begin{document} \( \bmod{\mathcal{N}} \) \( x^{\bmod{\mathcal{N}}} \) \end{document}

Adopting the code from this answer and the linked answers, I would like to be able to adjusting the kerning between math characters (notably the spacing around parentheses/brackets). However, the code seems not to be always effective. For instance, in the following example, the configuration between (/[ and 𝑓 is working, but the kerning between characters (like 𝑓 and 𝑓, 𝑐 and 𝑓) does not work; if one uncomment the line \setmathfont[RawFeature=+mathcharkern]{Asana-Math.otf}... (i.e., using symbols from one font, and using characters from another font), then the specified kerning between 𝑐 and 𝑓 appears to work; but the kerning between (/[ and 𝑓 now fail to work, and the kerning between characters 𝑓 and 𝑓 still don't work. Is there perhaps something wrong in my configuration? Why cannot this code work as expected in general, and how to make it work in all situations? \documentclass{article} \usepackage{showkerning} \RequirePackage{luacode} \begin{luacode*} fonts.handlers.otf.addfeature { name = "mathcharkern", type = "kern", data = { ["("] = { ["𝑓"] = 300, }, ["["] = { ["𝑓"] = 300, }, ["𝑓"] = { ["𝑓"] = 500, }, ["𝑐"] = { -- c ["𝑓"] = 500, }, }, } \end{luacode*} \usepackage{unicode-math} \setmathfont[RawFeature=+mathcharkern]{KpMath-Regular.otf} % \setmathfont[RawFeature=+mathcharkern]{Asana-Math.otf}[range={it/{Latin,latin},bfit/{Latin,latin},up/num,bfup/num}] \begin{document} % \addfontfeature{+mathcharkern} \( (ff) \) \( [ff] \) \( cf \) \end{document} Modified code based on Clea F.

I am trying to explore how robust Typst is as an alternative to LaTeX by trying to convert some documents from LaTeX to Typst. One limitation I ran into is fonts, as some fonts standard to some mathematical circles aren't built into the Typst compiler. Moreover, Typst only accesses external fonts through .ttf and .otf files, which means any fonts that don't have versions with these files aren't gonna be able to make the jump, or at least not easily. Case in point, the mathrsfs font, used for things like Schwartz spaces or spaces of distributions in Distribution theory, or Lagrangian and Hamiltonian density in Quantum Field Theory, doesn't have .otf or .ttf files, as seen here. Now, as outlined in this post, there is a way to convert it from .pfb to .otf using Font Forge. However, kerning doesn't work for basic characters or subscripts/superscripts. Thus, did the conversion from .pfb to .otf destroy built-in kerning information, or does LaTeX store kerning information somewhere else, because kerning works just fine in LaTeX with \mathscr? EDIT: Okay, I've learned that the .afm files also provided in the same location are what hold the kerning information for the font. However, that leaves me more confused, because looking at, e.g. rsfs10.afm, we have: StartFontMetrics 2.0 Comment Copyright Conversion from mf curves by Metafog (c) 1995 Richard Kinch Comment Panose 3 0 5 5 4 0 0 9 0 2 FullName rsfs10 FontName rsfs10 FamilyName rsfs10 Weight Roman Notice Copyright (c) Taco Hoekwater, 1998.

I suppose it could be the sizing of the bounding boxes, but if that's so, why is Typst having issues?

I know that I can make circular diagrams with the nice smartdiagram package, but arrows do not fit perfectly in a imaginary circle. In fact, the diagram is far from a circle when there are only two or three nodes: \documentclass{standalone} \usepackage{smartdiagram} \begin{document} \smartdiagramset{ connection color=red, module shape= circle, circular distance=2cm, uniform color list=white for 6 items, uniform arrow color=true, arrow color=black} \smartdiagram[circular diagram:clockwise]{foo, bar} \end{document} I know also that there are several examples in this site about making circular diagrams without this package, but translating these examples to diagrams with a different numbers of nodes is complex, so I tried an automated solution with tikz (without really knowing what I was doing, I have to admit) so that I only have to modify a list of nodes in \mylist and little more to obtain the result: \documentclass[border=2mm]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[ > = Stealth, every node/.style = {circle, draw, thick, minimum width=1cm, align=center} ] \def\mylist{foo, bar, baz} % play with this \foreach \x [count=\i from 1] in \mylist {\xdef\n{\i}} \def\radio{2cm} % and this if needed \foreach \texto [count=\i from 0] in \mylist{ \pgfmathsetmacro\ang{-\i*360/\n} \node (n\i) at (\ang:\radio) {\texto}; } \foreach \dummy [count=\i from 0] in \mylist{ \pgfmathsetmacro\j{int(mod(\i+1,\n))} \pgfmathsetmacro\angini{-\i*360/\n} \pgfmathsetmacro\angfin{-\j*360/\n} \pgfmathsetmacro\outang{mod(\angini - 90 + 720, 360)} \pgfmathsetmacro\inang {mod(\angfin + 90 + 720, 360)} \draw[->, thick, line width=1.4pt] (n\i) to[out=\outang, in=\inang, looseness=.9] (n\j); % and with the looseness } \end{tikzpicture} \end{document} Mainly it works. The problem is that like in smartdiagram, the arrows don't perfectly follow an imaginary circle, that was the idea behind getting involved in this business. Playing with looseness is possible to correct a bit the curvature of the arrows, but it's tedious and the result is never perfect. So, the result should be ideally near to the image below (that I modified manually in Inkscape) and still require minimal settings to adapt the code to diagrams of n nodes. Fixes of the MWE as well as alternative approaches are welcome. Edit Thank you all for the excellent suggestions. This time, I am truly sorry I can only accept one.

The question is rather simple. How to obtain the following big asterisk symbol? I apologize if it is duplicate. Thank you very much.

I want to do something like this : display binary operation evaluation in different ways (decomposing the binary evaluation in two unary evaluation, etc) with a much simple syntax, i.e. : Here I use postfix and infix notation for function applications, for example : in row 7 of this table, (c1 → c2) can be decomposed into c2 (c1 → _) , in which (c1 → _) is the first unary application (marked with blue framed box), c2 (c1 → _) is the second one (marked with blue framed box); and Homo stands for the Hom functor, Expo stands for Exponent operation in Cartesian Closed Category. However the compilation tooks so much time, I think I use too much \csname...\endcsname, \@ifnextchar and so on. Seeking for better solution like expl3 or LuaLaTeX.

What I’m trying to accomplish is best illustrated as follows: The first line (“Monday, December 22, 2025, 16:00 EST”) is right-aligned to the text width (possibly by \hfill, but not a hard requirement). The second line (“New York City, New York”) needs to be left-aligned to the left edge of that first line. In other words, the start of the M in “Monday” and N in “New York” are vertically aligned. How can this be done?
