The unicode-math package re-defines ellipsis to be the ellipsis character in whatever font you're using, instead of spaced dots. This looks bad in my opinion, and violates the guidance on ellipses in every style guide I own. A solution for \ldots is provided here: variations-in-ldots. But that solution does not fix \cdots, \vdots, or \ddots. I managed to find a solution for \cdots that works in this MWE, but seems to fail in other instances that I haven't figured out a reliable way to reproduce. And I can't figure out a solution for \vdots or \ddots at all. \documentclass{article} \usepackage{unicode-math} \AtBeginDocument{ % From https://tex.stackexchange.com/questions/120627/variations-in-ldots \renewcommand\mathellipsis{\mathinner{\ldotp\ldotp\ldotp}} \renewcommand\cdots{\mathinner{\cdotp\cdotp\cdotp}} % sometimes works %\renewcommand\vdots{\mathinner{\vdotp\vdotp\vdotp}} % doesn't work %\renewcommand\ddots{\mathinner{\ddotp\ddotp\ddotp}} % doesn't work } \begin{document} $\dots, \ldots, \cdots, \vdots, \ddots$ \end{document} Found an example of where my solution for \cdots didn't work. It's when \dots is used instead of \cdots explicitly to centrally place dots: \documentclass{article} \usepackage{unicode-math} \AtBeginDocument{ \renewcommand\mathellipsis{\mathinner{\ldotp\ldotp\ldotp}} \renewcommand\cdots{\mathinner{\cdotp\cdotp\cdotp}} % sometimes works } \begin{document} $x+\dots+ y$ % Do not get spaced dots $x+\cdots+ y$ % Do get spaced dots \end{document}

For the graphics I use on my physics exercise sheets made with TikZ I often use the same objects (hooks, masses, carts, pulleys, force gauges,...). So instead of copy-pasting and modifying the code of these objects I think it makes sense to make them into a ready to use object. There are three ways I know of to make that happen: TeX macros, pics and shapes. There are some features I wish the implementation of these objects to have and need some advice on how to implement it in order to have those features: An object should have multiple anchors so I can easily use certain points for further construction and choose which anchor to use for the placement (so there is no need to calculate that stuff manually). The hook for example could be placed at it's base or the actual hook and either one should be available afterwards for further placement of objects or paths. A default style should be set, i.e. the fill color or shading of the mass body, that can be overwritten. If placed inside a scope that changes shift, rotation, scale, line width,... these changes should automatically also apply to the object as a whole. I want to be able to construct new objects from already existing objects, i.e. I want to be able to use the hook as part of the mass, force gauge and cart. Right now I'm leaning towards defining new shapes, even tho I haven't used low level pgf before. As far as I can see 1 and 3 are no problem with shapes. I feel like 2 could also be achieved (any hints are appreciated - maybe defining a new style that uses that shape?). I however have no Idea if or how to make 4 work in defining a new shape. Pics on the other hand would make 2 and 4 easy as far as I can imagine. But they don't respond to the settings of a scope (3). Also anchors (1) are not natively supported but using tikzmark one answer to this question Anchoring TiKZ pics suggests this could be achieved as well (although I imagine it to be not quite as powerful as a new shape and takes two compilation runs if I understood correctly). Any thoughts, hints or pieces of advice are very welcome. I hope I described the setting clear enough. Edit The following Example is not meant to be beautiful but hopefully helps to illustrate the issue: \documentclass[tikz]{standalone} \usetikzlibrary{calc} \usetikzlibrary{tikzmark} \begin{document} \tikzset{ hook/.pic={ \draw[double=gray!80, double distance=1.4pt] (0,0) .. controls (0,-1.5) and (0,{1/sin(45)-2.5}) .. ($(45:1)+(0,-2.5)$) arc(405:140:1); \node[inner sep=2mm] (-hole) at (0,-2.5) {}; } } \tikzset{ cart/.pic={ \shadedraw[left color=blue, right color=blue!50] (-3,0) rectangle (3,2); \shadedraw[left color=black, right color=gray] (2,-.8) circle (.8); \shadedraw[left color=black, right color=gray] (-2,-.8) circle (.8); \pic[transform shape,rotate=90,scale=.5] (h) at (3,1) {hook}; \coordinate (-front-wheel) at (2,-1.6); \coordinate (-back-wheel) at (-2,-1.6); \node[inner sep=2mm] (-hook) at (h-hole) {}; } } \begin{tikzpicture} \draw (0,0) -- (8,0) -- (8,2); \pic[pic anchor=(-back-wheel),scale=.5] (cart) at (.5,0) {cart}; \pic[rotate=270,xscale=-1,scale=.25] (hook) at (8,0|-cart-hook) {hook}; \draw[ultra thick, line cap=round] (cart-hook) -- (hook-hole); \end{tikzpicture} \end{document} So using a pic with tikzmark (and transform shape as I've discovered) seems to check all the requirements. Can this also be achieved with a custom shape? As in this solution I dislike a few things: tikzmark needs two compilation runs no border anchors can be defined (at least I don't know how) It seems to me all anchors are defined every time a pic is inserted and not calculated when needed as with shapes. I'm not sure about the impacts on compilation time.

Task Consider the following: One needs to store a over time varying amount of pgfkeys entries with a nested data structure. All the entries have the same structure, but the content may vary. So one defines a macro to handle the pgfkeys structure initialization automatically when the user sets the data. Artificial Example: Inventory (MWE) \documentclass[parskip=full]{scrreprt} \usepackage{pgffor} \usepackage{pgfkeys} % DESCRIPTION: Set up inventory entries manually \pgfkeys{ /handlers/.is setter/.code=\pgfkeysedef{\pgfkeyscurrentpath}{% \noexpand\pgfqkeys{\pgfkeyscurrentpath}{##1}% },% /inventory/.cd, Manual 5 Speed/.is setter, Manual 5 Speed/inventory id/.initial = XXXXXXXXXX, Manual 5 Speed/product/.is setter,% Manual 5 Speed/product/manufacturer/.initial = EMPTY, Manual 5 Speed/product/product id/.initial = EMPTY, Manual 6 Speed/.is setter, Manual 6 Speed/inventory id/.initial = YYYYYYYYYY, Manual 6 Speed/product/.is setter,% Manual 6 Speed/product/manufacturer/.initial = EMPTY, Manual 6 Speed/product/product id/.initial = EMPTY } % DESCRIPTION: Logic for creating pgfkey "database" entry automatically and setting them to user specified data % ARGUMENTS: #1 = entry product, #2 = entry data \newcommand{\generateEntry}[2]{ % DESCRIPTION: Creating the pgfkeys "family" and intialize with default values \pgfkeys{ /handlers/.is setter/.code=\pgfkeysedef{\pgfkeyscurrentpath}{% \noexpand\pgfqkeys{\pgfkeyscurrentpath}{##1}% },% /inventory/#1/.cd, inventory id/.initial = ZZZZZZZZZZ, product/.is setter,% product/manufacturer/.initial = EMPTY, product/product id/.initial = EMPTY } % DESCRIPTION: Setting the data to the one specified by the user \pgfqkeys{/inventory/#1}{#2} } % DESCRIPTION: Macro for testing whether it is a problem with wrapping \pgfqkeys in an additional macro \newcommand{\setEntryData}[2]{ \pgfqkeys{/inventory/#1}{#2} } \begin{document} % DESCRIPTION: Setting the data of the manually added entry % with \pgfqkeys and "{}" notation % STATUS: WORKS AS EXPECTED \pgfqkeys{/inventory/Manual 5 Speed}{ inventory id = 6, product = { manufacturer = Herbert Motors, product id = 433M5 } } % DESCRIPTION: Setting the data of the manually added entry % with \pgfqkeys wrapped in macro and "{}" notation % STATUS: WORKS AS EXPECTED \setEntryData{Manual 6 Speed}{ inventory id = 11, product = { manufacturer = Herbert Motors, product id = 433M6 } } % DESCRIPTION: Generate and set data for automatic entry % with "/" notation % STATUS: WORKS AS EXPECTED \generateEntry{Automatic 4 Speed}{ inventory id = 21, product/manufacturer = Jane's Speedshop, product/product id = JS4A } % DESCRIPTION: Generate and set data for automatic entry % with "{}" notation % STATUS: FAILS FOR NESTED KEYS \generateEntry{Automatic 5 Speed}{ inventory id = 42, product = { manufacturer = Jane's Speedshop, product id = JS5A } } % DESCRIPTION: Visualize the data stored in the pgfkeys \section*{Inventory} \foreach \entry in {Manual 5 Speed, Manual 6 Speed, Automatic 4 Speed, Automatic 5 Speed}{ \textbf{\entry}:\\ inventory id: \pgfkeysvalueof{/inventory/\entry/inventory id}\\ manufacturer: \pgfkeysvalueof{/inventory/\entry/product/manufacturer}\\ product id: \pgfkeysvalueof{/inventory/\entry/product/product id} \\[0.25cm] } \end{document} This produces the following output: Issue When using the {...} notation to set the data of automatically generated entries, the data is not stored (see Automatic 5 Speed in MWE). The / notation seems to work. What was tried so far The problem seems to be related to the .is setter pgfkeys handler. It seems like the nested structure is not created, but a single key with e. g. product/manufacturer as id (with the / being interpreted as a letter, not a separator). So far, the following has been tried: Changing .code to .ecode Modifying the expansion from \noexpand to other possibilities Those experiments always resulted in errors and the compilation failing. Question Is there a simple way to achieve the desired behavior with pgfkeys (e.g. via .is family)? Suggestions of other methods are also welcome. However, solutions with pgfkeys would be preferred, since the rest of the data handling in the real project is already based upon pgfkeys.

I would have thought that if I declare \let\stdeqref\eqref, then the \stdeqref macro and the \eqref macro would be interchangeable. But here is an example where it fails! Moreover, this failure is (somehow) caused by the microtype package?! What is going on, and how to fix it? \documentclass{article} \usepackage{microtype} \usepackage{amsmath} \let\stdeqref\eqref \begin{document} \begin{equation}\label{a} A \end{equation} This is good spacing: \eqref{a}\allowbreak\eqref{a} This is bad spacing: \stdeqref{a}\allowbreak\stdeqref{a} But the bad spacing becomes good if we remove microtype! \end{document} The reason I'm asking is that I would like to redefine the \eqref macro in a way which uses the usual \eqref macro as a subcomponent, via the usual strategy I've seen time and time again on this site: \let\stdeqref\eqref \renewcommand\eqref[1]{Something fancy containing \stdeqref{#1} etc.} but that doesn't work anymore if \let isn't behaving as expected . . .

I'm using the enumext package to create multiple-choice questions. In my case, the answer labels are boxed letters, produced using the wrap-label key. The issue is that the boxed letters appear too close to each other vertically. I would like to know the correct way to increase the vertical spacing between the boxed labels, without unnecessarily changing the text spacing or breaking the column alignment. Here a MWE: \documentclass[a4paper,12pt]{article} \usepackage{amsmath, amssymb} \usepackage{graphicx} \usepackage{enumext} \begin{document} \begin{enumext}[label=\textbf{Domanda} \arabic*.,wrap-label=\textbf{#1},list-indent=0pt, save-ans=test] \item Lion \setenumext[keyans]{label=\Alph*,font=\small,nosep,wrap-label={\fbox{\makebox[\height]{##1}}}} \begin{keyans}[columns=2,nosep,mini-env={0.4\linewidth}] \item \item \item \item \miniright \includegraphics[scale=.4]{example-image.png} \end{keyans} \end{enumext} \end{document}

I'm typesetting my math document in Times New Roman using XeLaTeX and the fontspec package. I'm using mtpro2 as the math font, but I've noticed that certain letters, such as u, v and w, look quite different from their TNR italic counterparts (maybe because it's advertised as a Times-compatible font). Considering I'm already using the fontspec package, I tried ditching mtpro2 entirely and using other math fonts. I consulted the LaTeX Stack Exchange master list of maths fonts and tried XITS Math, TeX Gyre Termes Math and STIX Two Math. However, these fonts lack some features that I really like about mtpro2, such as round brackets (especially for matrices) and the letter z identical to the letter z in TNR. mtpro2 is here to stay. Next, I found the 'mathastext' package, which enables alphanumeric glyphs from the text font to be used in maths environments. For example, \usepackage[basic, italic]{mathastext} replaces all the alphanumeric characters in the maths font with the corresponding characters in the text font. However, this approach led me to another issue: the spacing between letters is awful, especially the subscripted ones. Since my only issue is with the letters u, v, and w, is there a way to just replace those three and use the rest of the mtpro2 glyphs? The code I'm using for my document is really bog standard: \documentclass{memoir} % Throw an error if this is not XeLaTeX. \usepackage{ifxetex} \RequireXeTeX \usepackage[lite]{mtpro2} \usepackage[no-math]{fontspec} \setmainfont{Times New Roman} \begin{document} \end{document} Any help would be appreciated.

The code is partially taken from egreg's this answer. I want to typeset the following three languages with three fonts: English: EB Garamond Chinese: FandolSong Greek: Old Standard Noted that I want to write an "English and Chinese" mixed article(which means that it need to switch frequently) to introduced the third language——Greek. As below: \documentclass{book} \usepackage{fontspec} \usepackage{polyglossia} \setmainlanguage{english} \setmainfont{EB Garamond}% English \newfontfamily{\chinesefont}{FandolSong}% Chinese \setotherlanguage{greek} \newfontfamily{\greekfont}{Old Standard}% Greek \begin{document} I want to typeset an article, whose main text is the combination of English, Chinese, which is used to introduced the Greek letters. I want three fonts for them. So, I want to use English and Chinese, switching frequently. And use Greek fonts in whole paragraph. \bigskip English: English Saṃskṛtāvāk Chinese: {\chinesefont 英语、中文 01234 这是一个测试} Greek: {\greekfont τὸν πόλεμον τῶν Ἀθηναῖος} It works well. However, what I want in the real case, is as follows: \bigskip An paragraph of English and Chinese, which shifts frequently. 我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。 {\chinesefont 我是英语} English {\chinesefont 和中文} Chinese {\chinesefont 混排。} is okay, but extremely difficult to switch... Then a paragraph of Greek letters. \textgreek{Θουκυδίδης Ἀθηναῖος ξυνέγραψε τὸν πόλεμον τῶν Πελοποννησίων καὶ Ἀθηναίων, ὡς ἐπολέμησαν πρὸς ἀλλήλους, ἀρξάμενος εὐθὺς καθισταμένου καὶ ἐλπίσας μέγαν τε ἔσεσθαι καὶ ἀξιολογώτατον τῶν προγεγενημένων, τεκμαιρόμενος ὅτι ἀκμάζοντές τε ᾖσαν ἐς αὐτὸν ἀμφότεροι παρασκευῇ τῇ πάσῃ καὶ τὸ ἄλλο Ἑλληνικὸν ὁρῶν ξυνιστάμενον πρὸς ἑκατέρους, τὸ μὲν εὐθύς, τὸ δὲ καὶ διανοούμενον.} It's hard for \texttt{polyglossia} to support an English font together another Chinese font.

I have also tried Fallback, but it doesn't work: \setmainfont[Fallback=FandolSong]{EB Garamond} If somebody get familiar with ctex-bundle, to set Chinese fonts and English fonts seperately, we could use: \usepackage{ctex} \setmainfont{EB Garamond} \setCJKmainfont{FandolSong} However, polyglossia is a little bit conflict with ctex(That maybe my another question or issues). So, this post, I was only after for a ployglossia(or babel) solution.

For example, what if $n$ equals 2? \begin{block}{} Then the question reduces to the following: \begin{align} \left(ax_{1}+by_{1}\right)+\left(ax_{2}+by_{2}\right) & \,\,\,=\,\,\,a(x_{1}+x_{2})+b(y_{1}+y_{2})\\ & \Longleftrightarrow\\ \left(ax_{1}+ax_{2}\right)+\left(by_{1}+by_{2}\right) & \,\,\,=\,\,\,a(x_{1}+x_{2})+b(y_{1}+y_{2}) \end{align} \end{block} \item We're summing the same numbers, just in a different order! \end{itemize} \end{frame} \end{document} Here is the result that I get: I understand there is no so much vertical space at the top, but I would still rather have the "Theorem" text start just after the mini frames, rather than content go off the page. Maybe what I'm asking for is "vfill" behavior, where it stretches or squeezes depending on the situation?

I searched for something similar, but I didn't find anything. \documentclass{report} \usepackage{amsmath} \usepackage{mathtools} \DeclareMathOperator{\diff}{d} \begin{document} \[\int x\diff x\] \end{document} I want to get "dx" and not "d x". I was looking at ways to eat spaces after the command, but nothing, I would like to avoid adding the "x" as a parameter to the \diff operator. I would like you know if there is a way.

In the following code, the \sum in \smashoperator appears too big.

Using the BaskervilleF font with instructions from here, \mathit{ff} produces fb instead of ff. Normal text, \textit and normal math modes are unaffected. MWE (commented lines are from the BaskervilleF instructions but don't seem to affect the issue): \documentclass[letterpaper,12pt]{book} \usepackage[utf8]{inputenc} % for baskerville font \usepackage[T1]{fontenc} \usepackage{baskervillef} %\usepackage[varqu,varl,var0]{inconsolata} %\usepackage[scale=.95,type1]{cabin} \usepackage[baskerville, varbb]{newtxmath} %\usepackage[cal=boondoxo]{mathalfa} \begin{document} normal: diff math: $diff$ it: \textit{diff} mathit: $\mathit{diff}$ \end{document} I'm not sure if that's an intended feature of the font, but either way it makes for confusing equations. Removing newtxmath solves it but changes the style of math too much. Is there a way to fix that while keeping the math font style and the normal ligatures of 'ff' in the text?

All is in the title: I have a current document with (plain) numbered pages and I would like to interleave blank pages but only after current page 3, that is, put one blank page between every plain page, starting from page 3 (so keep my current pages 1, 2, 3 unchanged, then start interleaving blank pages). These blank pages should be either numbered or not numbered but keeping the numbering of the plain pages coherent (i.e., I don't want to go from plain page 4 to 6). I can not use newpage since of course, I don't exactly know where the page breaks might occur regarding the content. Thanks in advance for help !

About 15 years ago, I had created a drawing using GeoGebra that looks similar to the attached image. The source .ggb file from GeoGebra is available here, and I'm happy to share it with anyone interested. I was wondering if it's possible to replicate this drawing exactly using TikZ-PGF. I have the .ggb file and I'm wondering if there's a way to convert it or if TikZ can reproduce the same graphic. Additionally, I found a more recent package, named pst-sphericaltrochoid, which might be useful for generating spherical trochoid curves, and the package is documented in the PDF manual from December 25, 2025. Moreover, I would like to have this drawing animated in LaTeX. When export in tikz-pgf using Geogebra the output is not the expected result like the image (with animations). I never done a drawing with animate package or similar. \documentclass[10pt]{article} \usepackage{pgfplots} \pgfplotsset{compat=1.15} \usepackage{mathrsfs} \usetikzlibrary{arrows} \pagestyle{empty} \begin{document} \definecolor{ffwwqq}{rgb}{1,0.4,0} \definecolor{zzttqq}{rgb}{0.6,0.2,0} \definecolor{xdxdff}{rgb}{0.49019607843137253,0.49019607843137253,1} \begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=1cm,y=1cm] \begin{axis}[ x=1cm,y=1cm, axis lines=middle, grid style=dashed, xmin=-24.649425971185988, xmax=51.05123247996474, ymin=-17.77843276444837, ymax=20.90166759086156, xtick={-20,-15,...,50}, ytick={-15,-10,...,20},] \clip(-24.649425971185988,-17.77843276444837) rectangle (51.05123247996474,20.90166759086156); \draw [line width=0.8pt] (0,0) circle (8cm); \draw [line width=0.8pt] (4.690951292494638,6.480353074597315) circle (2cm); \draw[line width=4pt] (-22.73456951795283,17.710240168806287) -- (-9.968859829731798,17.710240168806287); \draw[line width=4pt] (-22.73456951795283,15.157098231162069) -- (-9.968859829731798,15.157098231162069); \begin{scriptsize} \draw [fill=xdxdff] (4.690951292494638,6.480353074597315) circle (0.5pt); \draw[color=xdxdff] (4.137249375752443,7.338101047126645) node {$A$}; \draw [fill=black] (-17.202761986390385,17.710240168806287) circle (2.5pt); \draw[color=black] (-16.096400480077897,19.40169670249558) node {$k = 1.3$}; \draw [fill=zzttqq] (2.345168103332513,5.359058630909856) circle (1pt); \draw[color=zzttqq] (4.392563569516864,6.316844272068956) node {$Pianeta$}; \draw [fill=black] (-17.06092076763237,15.157098231162069) circle (2.5pt); \draw[color=black] (-16.479371770724526,16.848554764851364) node {$v = 5$}; \draw [color=ffwwqq] (0,0) circle (4.5pt); \draw[color=ffwwqq] (1.264964695902711,1.4658745905449386) node {$Sole$}; \end{scriptsize} \end{axis} \end{tikzpicture} \end{document} My idea is to animate the drawing using the animate package for my students of an high school, with the ability to modify parameters and see how the drawing changes in real time. Could I add interactive buttons to allow users to modify the parameters of the animation? If anyone has experience animating drawings in LaTeX, I'd be happy to receive suggestions on how to implement it. Also, how can I animate package this drawing and add interactive buttons to control the parameters?

I'm thinking about migrating several large documents from cleveref to zref-clever. I have read Migration from cleveref to zref-clever as well as the manual, but several questions remain. One of them is: How I can control whether references to equations include "equation" or "equations" before the label(s), independently of whether references to figures and tables include "figure" and "table"? (The reasoning is that equations are numbered with parentheses whereas figures and tables are numbered without parentheses. Thus, it is clear that "see (1)" means equation (1) whereas "see 1" would be ambiguous because it could mean either Figure 1 or Table 1.) My understanding is that I need to use the option noname when referring to each equation. To avoid having to type the option in each reference, I could define a new command: \documentclass{article} \usepackage{zref-clever} \newcommand{\zcrefeq}[1]{\zcref[noname]{#1}} \begin{document} \begin{equation}\label{eq:1} a = b \end{equation} \begin{figure}[h] \caption{Some figure.} \label{fig:1} \end{figure} We have \zcrefeq{eq:1} and \zcref{fig:1}. \zcref[S]{eq:1} is the first equation. \end{document} Is there a more elegant way of doing this by setting an overall option or a reference format option?

First of all "Merry Christmas" to everyone. I'm trying to get decimal output with luacas and don't get it. \documentclass[paper=a4,fontsize=12pt]{scrartcl} \usepackage{luacas} \begin{document} \directlua{ a=3 b=8 c=a/b tex.print('$',c,'$') } \end{document} The code above gives the expectet 0.375. Changing to \documentclass[paper=a4,fontsize=12pt]{scrartcl} \usepackage{luacas} \begin{document} \begin{CAS} a=3 b=8 c=Rational(a,b) \end{CAS} $\print{a}$ $\print{b}$ $\print{c}$ $\print{c.numerator}$ $\print{c.denominator}$ \end{document} gives 3, 8, the fraction 3 over 8, 3 and 8. In the manual there is the funtion :asnumber() given but \documentclass[paper=a4,fontsize=12pt]{scrartcl} \usepackage{luacas} \begin{document} \begin{CAS} a=3 b=8 c=Rational(a,b) d=c:asnumber() \end{CAS} $\print{a}$ $\print{b}$ $\print{c}$ $\print{c.numerator}$ $\print{c.denominator}$ $\print{d}$ \end{document} gives Lua-Error and the $\print{d}$ is ignored. I also tried something like d=Rational:asnumber(c) or used the funktions ZZ(), QQ() and RR() but without any success. Also $\print{c:asnumber()}$ fails. Trying to print the decimal with $\directlua{tex.print(string.format("\csstring\%.3f",c))}$ gives also a Lua error ('c' is a table but a number is expected by 'string.format()'). I'm not having any ideas how to solve it any more. Thank you for your help.
