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.

To increase the space between words (before trying ConTeXt), I was doing the equivalent of: \definecommand Wspc 1.4 \setupbodyfont[libertinus,12pt,serif,regular] {\switchtobodyfont[libertinus] \fontdimen2\font=\Wspc\fontdimen2\font} I see in this tex.se answer that it is referred to as an "ugly hack" and is not recommended. Is there a more acceptable way to increase the word spacing for the body font of the document? Thank you.

It appears that \setupinitial and \placeinitial are the method used to generate drop caps. May I ask a couple general questions, please. In the first example with the "I", how can the second and third lines be shifted to the right? I suppose, instead, the distance could be increased and the first line shifted to the left. In the second and third examples, is it possible to slope the distance to follow the "A" and "W" slopes? In the "I", the three lines of text appear to be aligned vertically; but, with the "A" and "W", the first line ("E") appears to be a bit more to the left than the other two lines. Why is this? Can the LibInit font be defined as 12pt such that the value of n in \setupinitials will set its size? I tried to do so, but it was either turned to bold or appeared as 12pt at the bottom of the third line. Thank you. (I received a lot of help the past couple days and thank you for that. I don't expect an answer to these four points, I just wanted to explain what I would like to do and, perhaps, someone can point me to where I can learn to do so.) \mainlanguage[en] \setuplayout[textwidth=4.0in] \setupbodyfont[libertinus,12pt,serif,regular] \definefont [LibInit] [name:LibertinusSerifInitials-Regular*default at 54pt] \definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupalign[justified,hyphenated,hanging,hz] \starttext \setupinitial[n=3,m=1,font=normal,hoffset=7pt,distance=-0.2em] \placeinitial {\LibInit I}Ellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.

In the following code, the \sum in \smashoperator appears too big. But if I put \textstyle\sum in \smashoperator, then it gives the error "*.tex: error: 290: Limit controls must follow a math operator. ...extstyle\sum_{\alpha\in D_{1}\cup D_{2}}}". I don't know what to do and need help.

When using LaTeX, to keep Libertinus font looking crisp, I used the microtype package with expansion and shrink "turned off". \usepackage[expansion=false,shrink=0]{microtype} Now, attempting to set the same document in ConTeXt to learn, I'm having the same issue with the font looking thicker and blurry than that in the former LaTeX document with the mentioned package and settings. Does \showfontexpansion still function? I'd like to see the default settings before attempting to alter them; but just including this command in the .tex file doesn't show anything in the PDF produced. Also, does \noexpansion still function? Using it appeared to change nothing in my document and I cannot find documentation for either of these commands on the contextgarden site, although they are mentioned at https://wiki.contextgarden.net/Command/setupfontexpansion. I ask because I'm trying to read the the ConTeXt book Typographic Programming and several of the commands shown are not in the manual that lists all the commands. For example, \setupfonthandling is one of them. Thank you.

I'm wondering if there are predefined symbols chromosomes-dna in pdfLaTeX or done in TikZ similar to those used in biology textbooks. Here two examples: (credit from wikipedia https://en.wikipedia.org/wiki/Chromosome#/media/File:Chromosome.svg)

I'm currently creating a presentation with the beamer package. Since the comment-environment doesn't work there, which is quite annoying, I want to ask if there is someone who has like a self-created usepackage or kind of hacks that provide the \begin{comment}...comment...\end{comment} - environment- function. There is already a similar question to this problem, but this solution creates a frame (of course without the comment but its a frame). I don't want the frame, so is there an option to 'hide' entire frames (so they aren't shown in the presentation)? \documentclass{beamer} \usepackage{comment} \begin{document} \begin{frame}[fragile] % fragile option random text \begin{comment} hidden text \end{comment} \end{frame} \end{document} This creates a frame without the hidden text, but I dont want the appearence of the frame in the presentation.

I apologize for asking what might be a very stupid question but ... is there a difference between installing ConTeXt from the install page and download page of the Pragma ADE site? I used the method on the install page, but there appear to be more files in the download zip; and the use of the phrase "minimalistic installation" in the pdf instructions made me wonder if that refers to the "amount" of ConTeXt installed or just the simplicity of the installation of it. If I followed the instructions in the archive from the install page, did I get the full installation or might I be missing something? It (LMTX version) looks to be about 366 MiB after running sh install.sh. Running Manjaro Linux on local desktop.

I managed to set the value of the bibtex field URL if the field stableurl is defined. I usually do not use the content of the field, since I believe organizations should provide DOIs. But some publisher insists. So I want to map the field stableurl to url and by doing so make it visible. The next step would be to add a value for last access and it should be \today. I could not manage to set the urldate value. My code sets it for all items.

I found that latex engines create various pieces of meta-data, some in Info dictionary, a lot in XMP data and some custom data like the banner tagging data. All pieces of data i am aware of can be displayed with pdfinfo using no option, -custom or -meta or -struct(-text). I know that the latex engines themselves write meta data, that the package hyperref writes further and \DocumentMetadata is another source. So if this is all, I really know the complete set of metadata written. It turns out that pdfinfo can visualize all of it. Can anyone confirm, that there is no more than that? I ask because for privacy I would like to avoid that the PDF file contains invisible data i am not aware of.

I have seen some nice examples from the Millennial font package. However, I couldn't find it anywhere in the Internet. I've tried http://www.math.unl.edu/~shartke2/computer/latex/Millennial-20110819.tar.bz2 but Professor Stephen Hartke, the package's author leaved UNL in 2015 so, although some files are available from Internet Archive like the character's test, the page is gone and so the package there. Even on Reddit I couldn't get a valid link, so I'm humbling asking if anyone here hold a copy of it that you could share. I know it's old and there are modern alternatives to it but, for some of my purposes, this T1 package would come in handy.

I'm trying to get my printout to match my page settings in ConTeXt. My printer sets margins of 0.17 inches and I cannot set them to 0. So, I reduced the leftedge, rightedge, backspace, topspace, top, and bottom by 0.17, which reduced the text width and height by 0.34. The \showlayout lists the expected values for each dimension; and I set \definepapersize[book][width=8.16in,height=10.66in][letter]. My question is, What is the correct way to set the positioning of the print on the paper? In the printer settings, I set PDF Options Scale to "None; print original size"; and that seems to result in the correct widths and heighths when measured with a ruler. (The default is "Fit to printable area" which I thought might result in no scaling since the page size should now be the same as the printable area; but that scales it down to slightly smaller dimensions.) However, the text does not appear to be positioned correctly horizontally. I'm trying to have facing pages using \setuppagenumbering[alternative=doublesided] but on one side the width of the inner margin (the distance from paper edge to text) differs a little from that on the opposite page. The left page is about 1/16 inch more than the target of 1.5 inches and the right page about 1/16 inch less. Is this just a printer issue or is there a setting, such as location that requires a value? I've been using location=doublesided. Thank you. \mainlanguage[en] \definepapersize[book][width=8.16in,height=10.66in][letter] \setuppapersize[book] \setuppagenumbering[alternative=doublesided] \definelayout[main][ location=doublesided, backspace=1.33in, topspace=0.83in, top=0.83in, topdistance=0in, width=fit, height=fit, headerdistance=0.125in, footerdistance=0in, header=15pt, footer=0in, bottom=0.83in, bottomdistance=0in, leftmargin=0in, leftmargindistance=0in, leftedge=1.33in, leftedgedistance=0in, rightmargin=1.375in, rightmargindistance=0.125in, rightedge=0.33in, rightedgedistance=0in] \setupbodyfont[libertinus,12pt] \setupindenting[yes,medium,next] \setupwhitespace[quarterline] \setupinterlinespace[2.8ex] \starttext \setuplayout[main] \showlayout[pt,in] \showframe {The text width is \the\textwidth, \the\rightedgewidth} \stoptext

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 trying with: \documentclass[]{article} \usepackage[numbers,super,sort&compress,comma]{natbib} \begin{document} Test\cite{ref1,ref2,ref3,ref4,ref5,ref6,ref7,ref8,ref9,ref10} \begin{thebibliography}{99} \bibitem{ref1} Entry 1 \bibitem{ref2} Entry 2 \bibitem{ref3} Entry 3 \bibitem{ref4} Entry 4 \bibitem{ref5} Entry 5 \bibitem{ref6} Entry 6 \bibitem{ref7} Entry 7 \bibitem{ref8} Entry 8 \bibitem{ref9} Entry 9 \bibitem{ref10} Entry 10 \end{thebibliography} \end{document} For HTML conversion, I'm trying with make4ht filename and the output was: If I remove the option super, then it works correctly: But I'm in need to use options numbers,super,sort&compress,comma, how can I meet this? Please advise.

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.

I noticed that paragraphs within the scope of a wrapstuff environment have larger horizontal distances between the title and the content. See for example \documentclass[b5paper]{article} \usepackage{graphicx} \usepackage[margin=2cm]{geometry} \usepackage{lipsum} \usepackage{wrapstuff} \begin{document} \begin{wrapstuff}[l,width=16em] \includegraphics[width=16em]{example-image} \end{wrapstuff} \paragraph{paragraph name}\lipsum[4] \paragraph{paragraph name}\lipsum[4] \end{document} The difference is very obvious and ugly in certain cases. What is the cause for this and how to solve the problem?

I noticed that when I start from a custom environment, and then decide to do something slightly non-trivial with its content (like hide it, or typeset in a different color), I end up switching to a custom macro with an argument. Consider, for example, these questions: Hide custom environment content based on boolean Environment hiding its content I have no idea how to make the content of an environment disappear without using packages like comment or version or scontents. On the other hand, this is trivial to do with a custom macro: just (re)define the macro as a no-op: \newcommand\comment[1]{}. It looks to me that any environment could be replaced with a macro, to have \theorem{...} instead of \begin{theorem}...\end{theorem}, etc. On the other hand, I do not know how to make an environment that, for example, duplicates or discards its content, or puts it in a box. What are the advantages of environments over macros that offset the inconveniences? P.S. IMO the environ package takes the correct approach.
