I think in 2019 I built the following image with Adobe Illustrator for my book. Now, since there are so many images in pdf, I am slowly creating them in TikZ code. I wanted to know if there is something to create a trail for the blue particle similar to the main image or any other idea you have. Thank you. \documentclass{article} \usepackage{tikz} \usetikzlibrary{arrows.meta} \tikzset{rhtip/.tip={Triangle[line width=1pt, fill=white, length=9pt, width=9pt]}, pics/clock/.style args={#1/#2}{ code={ \def\dist{0.38} \draw[thin] (0,0) circle (\dist); \draw[line width=.7pt] (0,0) -- ({0.16*cos(90-30*#1-0.5*#2)}, {0.16*sin(90-30*#1-0.5*#2)}); \draw[line width=.7pt] (0,0) -- ({0.28*cos(90-6*#2)}, {0.28*sin(90-6*#2)}); } } } \begin{document} \begin{tikzpicture}[scale=.8] \draw[->] (0,0) -- (4.8,0) node[right] {$x$}; \draw[->] (0,0) -- (0,4.8) node[above] {$z$}; \draw[->] (0,0) -- (1.8,1.1) node[above] {$y$}; \node at (-0.4,4.3) {$\Sigma$}; \shade[ball color=cyan] (2.7,1.2) circle (0.2); \draw[brown!80!black,line width=2pt,-rhtip] (2.9,1.2)--(3.8,1.2) node[midway,above left] {$\mathbf{u}$}; \pic at (2.5,2.5) {clock={1/10}}; \node[blue!60!black] at (3.35,2.9) {$C(u)$}; \begin{scope}[shift={(5,1)}] \draw[->] (0,0)--(4.5,0) node[right] {$x'$}; \draw[->] (0,0)--(0,4.8) node[above] {$z'$}; \draw[->] (0,0)--(1.8,1.1) node[above] {$y'$}; \node at (-0.4,4.3) {$\Sigma'$}; \draw[magenta,line width=2pt,-rhtip] (0,3.6)--(1.8,3.6) node[midway,above] {$\mathbf{v}$}; \draw[green!60!black,line width=2pt,-rhtip] (2.1,1.3)--(3.7,1.3) node[midway,below] {$\mathbf{u}'$}; \pic at (2.5,2.5) {clock={2/20}}; \node[blue!60!black] at (3.55,2.9) {$C'(u')$}; \end{scope} \end{tikzpicture} \end{document}

This post is the follow-up of my previous question and jlab's answer, together with the comment: You can't use custom arrows with \hreac. It's why I redefined an existing one. Here below is the code to show "You can't use custom arrows with \hreac." % https://tex.stackexchange.com/a/764525 % https://tex.stackexchange.com/a/484655 \documentclass{article} \usepackage{chemfig} \ExplSyntaxOn \definearrow3{===}{% \CF_arrowshiftnodes{#3}% \path[allow ~ upside ~ down](\CF_arrowstartnode)--(\CF_arrowendnode)% node[pos=0,sloped,yshift=\CF_arrowdoublesep](\CF_arrowstartnode @u0){}% node[pos=0,sloped,yshift=-\CF_arrowdoublesep](\CF_arrowstartnode @d0){}% node[pos=1,sloped,yshift=\CF_arrowdoublesep](\CF_arrowstartnode @u1){}% node[pos=1,sloped,yshift=-\CF_arrowdoublesep](\CF_arrowstartnode @d1){};% \draw (\CF_arrowstartnode @u0)--(\CF_arrowstartnode @u1);% \draw (\CF_arrowstartnode @d1)--(\CF_arrowstartnode @d0);% \CF_arrowdisplaylabel{#1}{0.5}+\CF_arrowstartnode{#2}{0.5}-\CF_arrowendnode% } \ExplSyntaxOff \begin{document} \schemestart A\arrow{===}B \schemestop \hreac A >{===} B \endhreac \end{document} The custom arrow style === here, was allowed in \schemestart...\schemeend, but NOT within \hreac...\endhreac: \CF_error ...e {Package \CFname \space Error: #1.} l.28 >{===} ?

If possible, if chemfig could provide more user-friendly interface to custom arrow, that would be better.

I am trying to create a two-column nomenclature section in LaTeX. My goal is to have the nomenclature entries fill the first column and then continue automatically in the second column on the same page (similar to the normal behavior of a two-column document). I am currently using the following code: \input{nomenclature} \begin{multicols}{2} \printnomenclature[0.06\textwidth] \end{multicols} The code successfully creates two columns, but the nomenclature only fills the first column. Instead of continuing to the second column on the same page, it starts a new page. I have attached an example showing the issue. Could anyone please suggest how to fix this problem or recommend a better approach? Thank you very much for your help. Here is one one of my example with the same problem: \documentclass[10pt,twocolumn,a4paper]{article} \usepackage{nomencl} \makenomenclature \usepackage{multicol} \begin{document} \title{Test} \author{} \date{} \maketitle % Problematic part \begin{multicols}{2} \printnomenclature[0.06\textwidth] \end{multicols} \nomenclature[Y]{AR}{Aspect Ratio} \nomenclature[Y]{EOC}{Extended Outlet Channel} \nomenclature[Y]{HEx}{Heat Exchanger} %Roman \nomenclature[A]{$a$}{Dimensionless thermal diffusivity} \nomenclature[A]{${A_{cr,d}}$}{As-designed cross-sectional area of channels in the HEx} \nomenclature[A]{${A_{s,d}}$}{As-designed surface area of the channels in the HEx} \nomenclature[A]{${A_{s,Iso,eff.}}$}{Isolation effective surface area} \nomenclature[A]{$A_j$}{Eigenfunction coefficient} \nomenclature[A]{Bi}{Biot number} \nomenclature[A]{$c_{p,m}$}{Specific heat capacity under constant pressure} \nomenclature[A]{$c_{s}$}{Mean adiabatic speed of sound} \nomenclature[A]{$D_h$}{Hydraulic diameter} % Greek \nomenclature[G]{$\alpha$}{mean heat transfer coefficient (Biot number calculations)} \nomenclature[G]{$\alpha_{CWHF}$}{mean heat transfer coefficient with the constant wall heat flux calculation methodology} \nomenclature[G]{$\alpha_{CWT}$}{mean heat transfer coefficient with the constant wall temperature calculation methodology} \nomenclature[G]{$\Delta p$}{pressure drop} \nomenclature[G]{$\Delta\xi$}{standard error of the arithmetic mean} \nomenclature[G]{$\zeta$}{measured quantity} \nomenclature[G]{$\Theta$}{Dimensionless temperature} \nomenclature[G]{$\theta$}{Alternative dimensionless temperature notation (if used)} \nomenclature[G]{$\lambda$}{mean heat conductivity (Biot number calculations)} \nomenclature[G]{$\lambda_m$}{mean heat conductivity} \nomenclature[G]{$\lambda_j$}{Eigenvalue (j-th mode)} \nomenclature[G]{$\mu_m$}{mean dynamic viscosity} \nomenclature[G]{$\Phi_j$}{Eigenfunction (j-th mode)} \nomenclature[G]{$\xi$}{arithmetic mean} \nomenclature[G]{$\rho$}{mean density} \nomenclature[G]{$\sigma$}{standard deviation} % Subscripts \nomenclature[L]{$0$}{Reference (2D thermally fully developed length calculations)} \nomenclature[L]{$avg.$}{Average} \nomenclature[L]{$b$}{Bulk} \nomenclature[L]{$con$}{Contraction} \nomenclature[L]{$expn$}{Expansion} \nomenclature[L]{$h$}{Hydraulic} \nomenclature[L]{$hyd$}{Hydrodynamic} \nomenclature[L]{$i$}{individual data point over time} \nomenclature[L]{$in$}{Inlet} \nomenclature[L]{$j$}{individual measurement position at one axial position} \nomenclature[L]{$m$}{Mean} \nomenclature[L]{$out$}{Outlet} \nomenclature[L]{$w$}{Wall} \nomenclature[L]{$\infty$}{Infinity} \end{document} I also created one additional TEX file to create nomenclature: TEXFile name(without .tex extension)= latexmkrc add_cus_dep('nlo', 'nls', 0, 'makenomenclature'); sub makenomenclature { system("makeindex -s nomencl.ist -o \"$_[0].nls\" \"$_[0].nlo\""); }

I want to set the main text font to Arial using:\setmainfont{Arial} but I don't want the font used by \mathbf to be affected by Arial. I want \mathbf to keep the original default font. How can I achieve this? The following is my code: \documentclass{ctexart} \usepackage{amsmath,amssymb} \setmainfont{Arial} \begin{document} Hello world! with \verb|\setmainfont{Arial}| $\mathbf{N}_{+}$ \end{document} which gives: Noted that \mathbf also changed the N, which was not I was after, I want the Hello world! to be sans serif with Arial, while the \mathbf{N} gives the default bold N symbol with latinmodernmath.otf, the serif one as below:

ps. I had help with google AI working on this, but it could not figure how to do it either. I am translating a document from LaTeX to ConTeXt. In LaTeX, I use \begin{figure}[H] (from the float package) to entirely disable floating. It forces the image to stay exactly where it is written, and guarantees that any text written below the figure code stays below it on the page (instead of flowing backward to fill vertical gaps). I am trying to achieve this same behavior in ConTeXt using the export=yes backend, but my text written after the figure keeps jumping above it if the image is pushed to a new page. Here is my context code, and below that the latex code and screen shot showing the difference. context: \setupbackend[export=yes] \setupwhitespace[big] \starttext And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text \startplacefigure[ title={This is the figure caption}, reference={fig:myimage}, location={force,none} %location={here,always} ] \externalfigure[image][width=0.95\textwidth] \stopplacefigure THIS TEXT SHOULD ALWAYS BE BELOW the image above. \stoptext compiling using context B.tex gives Here is the latex compiled with lualatex \documentclass[12pt,oneside]{book} \usepackage{graphicx} \usepackage{float} \begin{document} And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text And this is some text. some random text \begin{figure}[H] \centering \includegraphics[width=0.95\textwidth]{example-image-a} \end{figure} THIS TEXT SHOULD ALWAYS BE BELOW the image above. \end{document} This is the PDF I have tried location={force}, location={here,always}, and location={force,none}, but none of them match the absolute non-floating behavior of [H]. If the image is large, the trailing text still flows backward to the previous page. How can I turn off floating entirely for a \startplacefigure block while preserving the automatic numbering, caption title, and cross-reference hook? TL 2026 on Linux. ps. google AI also asked me to add this to my question: "Mentions export=yes: This is critical because some custom box hacks in ConTeXt bypass the exporter. Telling them you need the XML export ensures they provide a solution that safely preserves your tags for your Python script."

I know I can change the latex. But I have important reason for using \begin {array}{>{\displaystyle }r @{\;} >{\displaystyle }l} instead of say align or something else (too long to explain here, it depends on context I am using this latex code in). This is only a MWE to show the difference. So I do not want to change the latex code. ps. It should be possible to correct this using new mathjax configuration in my .cfg, but I am not sure how. I think I know of only one person who would know how to do this 🙂 Update Here is screen shot showing difference between fonts used by V 3.5 and V 4.0

I am using context. When I add this line to the .tex file in order to export an XML file: (If I do not add this, no XML will be generated) \setupbackend[export=yes] and say my file is called A.tex, context automatically creates a folder called A-export/ and then puts the created XML file inside this folder. I am using python to convert the XML to HTML. But the problem is that my image folder is now one level above where the XML file is. Here is the tree I have A.tex images/image_1.pdf %this folder has all images A-export/A.xml In my .tex code I have \externalfigure[images/image_1][width=0.75\textwidth] So when I cd to A-export folder and try to convert A.xml to A.htm, all references inside A.xml point to images/image_1 but this is not the correct path now, as this is relative to the parent folder. Question is: Is there a way to tell context NOT to create A-export/ at all, and just put the XML file and any other files it generates using the command content A.tex in same folder? This will make life much simpler. This way I can use my python convert script and not have to manually copy things around or adjust image file paths in XML each time? TL 2026 on Linux

I am trying to solve the same problem as the OP of this question, that is, set up some way to distinguish between equations and diagrams in a document and have it automatically be recognized by cleveref. The top answer there works beautifully... that is, as long as you don't load amsmath. If you do load it, then \cref will start referring to diagrams as equations again. For sake of self-containedness, here's an MWE based on that in the linked answer: \documentclass{article} \usepackage{tikz} \usetikzlibrary{cd} %\usepackage{amsmath} \usepackage{hyperref} \usepackage[noabbrev]{cleveref} \newcounter{diagram} \newenvironment{diagram}[1][]{% \begin{equation}% \begin{tikzcd}[#1]% \setcounter{diagram}{\value{equation}}% \addtocounter{diagram}{-1}% \refstepcounter{diagram}% }{% \end{tikzcd}% \end{equation}% } \crefname{diagram}{diagram}{diagrams} \creflabelformat{diagram}{(#2#1#3)} \begin{document} \begin{diagram}\label{diag:a} A \ar[r] & B \end{diagram} The above is \cref{diag:a}. \end{document} This produces the diagram together with "The above is diagram (1).", as desired. If you uncomment line 5, it instead produces the diagram with "The above is equation (1)." I'd be grateful for a solution with a similar use pattern that works in the presence of amsmath. In particular, I'd like to avoid the triple nesting \begin{diagram} \begin{equation} \begin{tikzcd} % ... \end{tikzcd} \end{equation} \end{diagram} that is common to the other answers at the linked question, if possible.

I noticed that the \lastpagenumber is always one higher than the actual amount of pages (for example, showing 2 in a one page PDF instead of 1). It does not depend on the number of pages, I have seen this in one, two and three page PDFs. This is my MWE: \setuppagenumbering[location=,] \starttext Current: \pagenumber \\ Last: \lastpagenumber \stoptext This also applies to \totalnumberofpages, \lastpage. My version is 2026.02.19 11:49. Thanks in advance!

Is it possible to right align the left upper and lower indices that characterize atomic properties using \chemfig? Example: \chemfig{^{14}_6C} prints out the following: However, I would like to have the following: How to get it? EDIT: adding a MWE \documentclass[border=1mm]{standalone} \usepackage{chemfig} \begin{document} \chemfig{^{14}_6C} \end{document}

Here is what I want to do in LaTeX but in Python, data = [ ('path/to/file1', 'Caption for file1.', 'fig:label1'), ('path/to/file2', 'Caption for file2.', 'fig:label2'), ('path/to/file3', 'Caption for file3.', 'fig:label3'), ('path/to/file4', 'Caption for file4.', 'fig:label4') ] for entry in data: print( f'\\begin{{figure}}[htbp]\n\ \\centering\n\ \\includegraphics[width=0.8\\textwidth]{{{entry[0]}}}\n\ \\caption{{{entry[1]}}}\n\ \\label{{{entry[2]}}}\n\\end{{figure}}' ) This will result in the following text over the console, \begin{figure}[htbp] \centering \includegraphics[width=0.8\textwidth]{path/to/file1} \caption{Caption for file1.} \label{fig:label1} \end{figure} \begin{figure}[htbp] \centering \includegraphics[width=0.8\textwidth]{path/to/file2} \caption{Caption for file2.} \label{fig:label2} \end{figure} \begin{figure}[htbp] \centering \includegraphics[width=0.8\textwidth]{path/to/file3} \caption{Caption for file3.} \label{fig:label3} \end{figure} \begin{figure}[htbp] \centering \includegraphics[width=0.8\textwidth]{path/to/file4} \caption{Caption for file4.} \label{fig:label4} \end{figure} How do I do this but in LaTeX? I know how to run simple loops like shown here: https://www.dickimaw-books.com/latex/admin/html/docsvlist.shtml \newcommand*{\mylist}{Parrot,Canary,Zebra,Arara,Duck}% \makeatletter \@for\thisitem:=\mylist\do{\thisitem. } \makeatother However, I not sure how to run a loop over a list of lists and index the inner list.

For a LaTeX class I'm currently working on, based on a graphic designer work, I need to change the \chapter command (roughly) as follows: the chapter title has to be typeset on a (odd) dedicated page, with a dedicated geometry, the two following pages, which contain the beginning of the chapter text, have to be typeset with a dedicated geometry, the following pages (until the next chapter) have to be typeset with the default geometry. The following MCE is a (clearly fragile) attempt to do so, which: works as expected with simple paragraphs (Lorem ipsum), doesn't work with a “real” document (\blinddocument), as shown: pages 3-7: the default geometry is restore starting on page 6, versus pages 9-13: the default geometry isn't restore starting on page 12. Do you understand what's going on and how to get the expected result? \documentclass{book} \usepackage{geometry} \usepackage{lipsum} \usepackage{fgruler} \usepackage{afterpage} \usepackage{blindtext} \geometry{ % Default geometry (small margin, just for the example) showframe, paperwidth=200mm, paperheight=250mm, margin=1cm } \renewcommand{\chapter}[1]{% \cleardoublepage \newgeometry{% Dedicated geometry for the chapter title (dedicated) page % (\newgeometry induces clearpage) tmargin=5cm, centering, } \thispagestyle{empty} \begin{center} \Huge\bfseries#1 % Chapter title \end{center} \newgeometry{% Dedicated geometry for the two pages following the chapter % title (dedicated) page tmargin=3cm } \afterpage{% On the following page \afterpage{% On the following page… \aftergroup\restoregeometry % … restore the default geometry } } } \begin{document} \fgruler*[type=in]{alledges} \lipsum[1] \chapter{Test} \lipsum[1-35] \blinddocument \lipsum[1-35] \end{document}

I am trying to place two TikZ figures side-by-side , but I am running into layout issues. In my document structure, I cannot use \resizebox or scale the figures, because there are too many elements that would conflict with my existing layout and typography constraints. For the same reason, I also want to avoid changing the x and y unit scales inside the TikZ pictures. My goal is to keep both figures at their natural size and still arrange them horizontally on the same line, respecting the page geometry. However, despite trying different approaches, the result is not satisfactory: the figures either overlap, break the margins, or force unwanted scaling. Is there a reliable way to force two TikZ pictures to stay side-by-side without resizing them and while respecting the page layout constraints? \documentclass{article} \usepackage[top=2.5cm,bottom=2.2cm, left=3.2cm,right=1.5cm,headsep=10pt,a4paper]{geometry} \usepackage{graphicx} \usepackage{subcaption} \usepackage{tikz} \usetikzlibrary{arrows.meta} \tikzset{ rhtip/.tip={ Triangle[ fill=white, line width=0.8pt, length=8pt, width=8pt ] } } \begin{document} \begin{figure}[htbp] \centering \begin{subfigure}{0.48\textwidth} \centering \begin{tikzpicture}[x=0.6cm,y=0.6cm, font=\large] \draw[->] (0,0)--(6,0) node[right]{$x$}; \draw[->] (0,0)--(0,4) node[above]{$y$}; \node[below left] at (0,0){$O$}; \node[draw,circle] at (-1,3){$\Sigma$}; \begin{scope}[shift={(1.1,1.1)}] \draw[->] (0,0)--(6,0) node[right]{$x'$}; \draw[->] (0,0)--(0,4) node[above]{$y'$}; \node[below right] at (0,0){$O'$}; \node[draw,circle] at (1.5,3){$\Sigma'$}; \end{scope} \draw[-rhtip, line width=2pt, red!80!black] (6.2,3)--(7.5,3); \node[below] at (6.85,2.8){$\mathbf{v}$}; \end{tikzpicture} \caption{$\Sigma'$ in moto rispetto a $\Sigma$} \end{subfigure} \begin{subfigure}{0.48\textwidth} \centering \begin{tikzpicture}[x=0.6cm,y=0.6cm, font=\large] \draw[->] (0,0)--(6,0) node[right]{$x$}; \draw[->] (0,0)--(0,4) node[above]{$y$}; \node[below left] at (0,0){$O$}; \node[draw,circle] at (-1,3){$\Sigma$}; \begin{scope}[shift={(1.1,1.1)}] \draw[->] (0,0)--(6,0) node[right]{$x'$}; \draw[->] (0,0)--(0,4) node[above]{$y'$}; \node[below right] at (0,0){$O'$}; \node[draw,circle] at (1.5,3){$\Sigma'$}; \end{scope} \draw[-rhtip, line width=2pt, orange!80!black] (7.5,3)--(6.2,3); \node[above] at (6.85,3.1){$-\mathbf{v}$}; \end{tikzpicture} \caption{Velocità relativa opposta} \end{subfigure} \caption{Due sistemi di riferimento inerziali in moto relativo rettilineo uniforme.} \end{figure} \end{document}

I want to plot the surface in this image: This "MWE" does not run, though it conveys what I'm trying to do. \documentclass[tikz,border=1cm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture}[ declare function={ f(\x,\y)=sqrt((\x/2)^2+(\y)^2-1); g(\x,\y)=f(\x,\y)/abs(f(\x,\y)); h(\x,\y)=1/(((\x-10)^2+(\y-2)^2)^2+1); i(\x,\y)=g(\x,\y)+h(\x+\y); j(\x,\y)=i(\x,\y)+1/((\x)^2+(\y+10)^2-1); } ] \begin{axis}[ hide axis, view={-30}{30}, scale=3, unit vector ratio=1 1 1 ] \addplot3[ surf, color=black, opacity=0.2, samples=10, samples y=10, domain = 1:15, domain y = 0:\fpeval{2*pi}, z buffer=sort, ] ( {x}, {y}, {j(x,y)} ); \end{axis} \end{tikzpicture} \end{document} When we tessellate a surface domain by taking a Cartesian product of sequences along both dimensions and triangulating the resulting grid, the result will ultimately neglect important features in nontrivial illustrations. In this particular case, there are small regions of exceptionally high detail, and a nonlinear ridge, while most of the surface is undetailed. Why in the world would we waste so many triangles on those regions, slowing down everything, when we could instead strategically sample the domain, and Delaunay triangulate? This questions seeks that. I want, and have been studying for some time, a domain tessellation technique which does this: samples along the boundaries of the domain like sewing along a seam. We would then be able to use a post triangulation filter to remove any simplices which are outsite this seam. samples point singularities explitly, as well as along singularity curves as though they were a seam. ALSO samples a "seam" around asymptotic regions, so that a boolean filter can remove post-triangulation simplices which are within the asymptotic region. This "seam" should be dependent on the strength of the asymptote, in terms of how closely we sample it. AND very importantly, it will strategically sample according to curvature, so that nondetailed regions aren't wastefully samples, allowing us to logistically sample regions of higher curvature. Samples important calculus based points, curves, and regions, such as maxima and minima (including when they are along ridges, as in my example), and inflection ploints (including the same), etc. In my view, this is one of the biggest problems facing modern mathematics illustration as a practise.

I'm trying to customize item labels within an enumerate list on the fly, using the item options. However, I don't fully understand how it works. The code below produces unexpected results, and different patterns emerge for the first layer of the list and the second layer of the list. I'm trying to do this without using the enumitem package, if possible. I know how to manually edit the items, but want the counter to be more automated in the inner list. Here is a minimum working example: \documentclass{article} \begin{document} \begin{enumerate} \item[\theenumi.] Why is this 0, instead of 1? \begin{enumerate} \item[\theenumii.] Why is this blank? \item[\theenumii.] Why is this blank? \item[\theenumii.] Why is this blank? \end{enumerate} \item And this adds one to the counter \item And this adds one to the counter \end{enumerate} \begin{enumerate} \setcounter{enumi}{1} \item[\theenumi.] Now this is 1, as expected. \begin{enumerate} \setcounter{enumii}{1} \item[\theenumii.] And this is a, as expected. \item[\theenumii.] Why doesn't this add one to the counter? \item[\theenumii.] Why doesn't this add one to the counter? \end{enumerate} \item And why does this still add one to the counter? \item And why does this still add one to the counter? \end{enumerate} \end{document} Here's the output:

This question might be off-topic, but the reason I ask it here is that I want to eventually create a module for a LaTeX package to enable the use of conic gradients via PDF Type 6 shadings which are also known as Coons Patch Mash Tiling. Also, please do not read this as "fix my issue for me" question. Rather, I appreciate any pointers to where I could be wrong. I understand that this topic is highly specialised, so I don't expect anybody to actually fix it completely or even partially. Now, as far as I understand, such shadings are essentially encoded as object stream in a PDF with the following object structure as basis (of course the object number and the contents of the stream and its length are different in a real document): 1 0 obj << /ShadingType 6 /ColorSpace /DeviceRGB /BitsPerCoordinate 16 /BitsPerComponent 8 /BitsPerFlag 2 /Decode [ 0 100 0 100 0 1 0 1 0 1 ] /Length 0 >> stream 00... endstream The stream defines the patches. Each path can be thought of a (distorted) rectangle of which the four sides are described as cubic Bézier curves. Therefore, each of the four edges of the patch has four control points, which means that there are twelve such points needed to describe a patch. Also, each corner of the patch is assigned a color. Now, in a mesh, the patches are attached to each other so that they share a common edge. To identify the shared edge, a flag is added to each patch which describes which edge is shared. A 0 flag identifies the initial patch, a 1 flag means that the right edge of the previous patch is used as the left edge of the current patch. There are more flags, but we only need these two for this case. If edges are shared, the relevant control points and colors are omitted in the description of the patch in the stream. So, if we take the sizes as described by /BitsPerCoordinate, \BitsPerComponent and /BitsPerFlag (let us assume 16, 8, and 2 respectively, also let us assume RGB), we get the following binary representation of the a patch with flag 0: Flag: 2 bits Points: 12 points, 16 bits for the x coordinate, 16 bits for the y coordinate Colors: 4 colors, 8 bits for the red part, 8 bits for the green part, 8 bits for the blue part For a patch with flag 1, we get: Flag: 2 bits Points: 8 points, 16 bits for the x coordinate, 16 bits for the y coordinate Colors: 2 colors, 8 bits for the red part, 8 bits for the green part, 8 bits for the blue part Maybe I got something wrong here already, which might explain why things don't work. Anyways, my question is why the following does not result in the desired output. My idea for a conic shading was to create patches that look like slices of a pie. Like this: I first tried without the rounded edge and just set the control points to be equal to the relevant corner, hoping that this would result in a triangle-shaped rectangle. So my patches would adhere to the following logic: Patch 1: Flag = 0 Points: (50, 50) (50, 50) (100, 50) (100, 50) (100, 50) (50, 100) (50, 100) (50, 100) (50, 50) (50, 50) (50, 50) (50, 50) Colors: (255,0,0) (191,0,64) (191,0,64) (255,0,0) Patch 2: Flag = 1 Points: (50, 100) (0, 50) (0, 50) (0, 50) (50, 50) (50, 50) (50, 50) (50, 50) Colors: (128,0,128) (128,0,128) Patch 3: Flag = 1 Points: (0, 50) (50, 0) (50, 0) (50, 0) (50, 50) (50, 50) (50, 50) (50, 50) Colors: (64,0,191) (64,0,191) Patch 4: Flag = 1 Points (50, 0) (100, 50) (100, 50) (100, 50) (50, 50) (50, 50) (50, 50) (50, 50) Colors: (0,0,255) (0,0,255) But, the output is totally not what it should look like although I think that the stream is correct. Acrobat also complains about something being wrong. It looks like this: 21 0 obj << /ShadingType 6 /ColorSpace /DeviceRGB /BitsPerCoordinate 16 /BitsPerComponent 8 /BitsPerFlag 2 /Decode [ 0 100 0 100 0 1 0 1 0 1 ] /Length 350 >> stream 20002000200020003FFFE0003FFFE0003FFFE00020003FFFE0003FFFE0003FFFE00020002000200020002000200020003FC0002FC0102FC0103FC00018000FFFF00008000000080000000800080008000800080008000800080008000800080800080400020002000000020000000200000002000200020002000200020002000200010002FD0002FD80000000FFFF8000FFFF8000FFFF8000800080008000800080008000800080000000FF0000FF endstream endobj So, my question is: What am I missing?

What package I have to use if I want to get French text in superscript? I want to write "57ème croche sur 92" with the term "ème" in superscript.

I use countwords to count the number of words in some LaTeX documents. The package counts words into a standard LaTeX counter. I then use totcount to display this wordcount at the beginning of the document. The number is generally in the thousands. Totcount provides a single macro \total{<counter>} for printing the eventual value of a counter, but it doesn't do any intelligent formatting, like dividing thousands with a comma/space (and fair enough -- very few situations call for counters in the thousands!). I would like to print the eventual value of the counter at the beginning of the document in a nicely formatted way. How can I do this? Based on other discussions of formatting counters, I have tried using numprint and siunitx, but neither of these work -- MWEs below. TIA!

I want to draw the graph of z = x^2 + y^2, and I am using tikz for that. I used the following command: \begin{tikzpicture}[ x={(1cm,0cm)}, y={(-0.6cm,-0.35cm)}, z={(0cm,1cm)}, line join=round, line cap=round, scale=1, ] % Axes \draw[->] (0,0,0) -- (2,0,0); \draw[->] (0,0,0) -- (0,2.5,0); \draw[->] (0,0,0) -- (0,0,4); % Graph \draw[thick,smooth,variable=\t,domain=-1.8:1.8] plot ({\t},{0},{\t*\t}); % Circle that gives a 3d impression \draw[thick,smooth,variable=\t,domain=0:360] plot ({1.8*sin(\t)},{1.8*cos(\t)},{3.24}); \end{tikzpicture} However, the circle does not "fit" the graph: How can I adjust this?

I have a complicated environment that scans for presence of tokens and "patches" them by adding some tokens before. I implemented this using macros with arguments delimited by the tokens I want to patch. Once the patching is done, I'd like to respect the token stream as much as possible (i.e. make it as close to the original as possible). However, whenever the text between the delimiters is exactly of the form "{ text }", the braces are sadly removed. I'd like to find a way to avoid this behavior. I had a look here but I'm afraid this will change the token stream too much, so I'm wondering if there is a simpler fix. Edit: Better MWE based on David's reply. Goal: Implement such a patch command so that the token stream after \patch is as close as possible (identical?) to the original one. \documentclass{article} \def\Z{Z} % Does not work with first def of \A \def\patch\A#1\Z{patched:\A#1\Z} % Does not work with second def of \A \def\patch\A#1{\xpatch\A{{#1}}} \def\xpatch\A#1\Z{patched:\A#1\Z} \begin{document} First def of A :\def\A#1{(A #1)} \A{arg} \Z \patch\A{arg} \Z \A{arg}\Z \patch\A{arg}\Z Second def of A:\def\A[#1]{(A #1)} \A[arg] \Z \patch\A[arg] \Z \A[arg]\Z \patch\A[arg]\Z \end{document} Output (first def of \A) (A arg) Z patched:(A arg) Z (A arg)Z patched:(A a)rgZ Thanks a lot for your help!
