Hot

I am trying to generate a quiz where I can generate a file answers.txt containing the id of each question, the x,y location on the page, the width,height and the answer. The macro side effects are brutal and I have no idea what is going on. The following minimal non-working example shows the error. I can try to save out the location of each one, but if I try to also print out width,height that give an error. \documentclass{article} \usepackage{xparse} \usepackage{tikz} \usepackage{zref-savepos} \newwrite\ansfile % Answer box size \newlength{\answ} \newlength{\ansh} \setlength{\answ}{36pt} \setlength{\ansh}{18pt} \newcounter{question} \newcounter{ansbox} % Parallel arrays stored as token lists \newtoks\AnsIDs \newtoks\AnsX \newtoks\AnsY \newtoks\AnsW \newtoks\AnsH \newtoks\AnsText \NewDocumentCommand{\question}{mm}{% \stepcounter{question}% \par\noindent\textbf{Q\thequestion\ (#1 pts)} #2\quad } \NewDocumentCommand{\ans}{m}{% \stepcounter{ansbox}% \edef\labelname{Q\thequestion-A\theansbox}% \zsavepos{\labelname}% \tikz[baseline]{\draw (0,0) rectangle (\answ,\ansh);}% % store in arrays \AnsIDs=\expandafter{\the\AnsIDs \labelname,}% \AnsX=\expandafter{\the\AnsX \zposx{\labelname},}% \AnsY=\expandafter{\the\AnsY \zposy{\labelname},}% \AnsW=\expandafter{\the\AnsW \strip@pt\answ,}% \AnsH=\expandafter{\the\AnsH \strip@pt\ansh,}% \AnsText=\expandafter{\the\AnsText #1,}% } \AtBeginDocument{% \immediate\openout\ansfile=answers.txt } \AtEndDocument{% % write arrays to file \def\IDList{\the\AnsIDs}% \def\XList{\the\AnsX}% \def\YList{\the\AnsY}% \def\WList{\the\AnsW}% \def\HList{\the\AnsH}% \def\TList{\the\AnsText}% \newcount\i \i=0 \loop \ifnum\i<\value{ansbox} % extract first item from each comma list \edef\currID{\expandafter\@firstofone\expandafter{\expandafter\@car\IDList\@nil}}% \edef\IDList{\expandafter\@gobble\IDList}% \edef\currX{\expandafter\@firstofone\expandafter{\expandafter\@car\XList\@nil}}% \edef\XList{\expandafter\@gobble\XList}% \edef\currY{\expandafter\@firstofone\expandafter{\expandafter\@car\YList\@nil}}% \edef\YList{\expandafter\@gobble\YList}% \edef\currW{\expandafter\@firstofone\expandafter{\expandafter\@car\WList\@nil}}% \edef\WList{\expandafter\@gobble\WList}% \edef\currH{\expandafter\@firstofone\expandafter{\expandafter\@car\HList\@nil}}% \edef\HList{\expandafter\@gobble\HList}% \edef\currA{\expandafter\@firstofone\expandafter{\expandafter\@car\TList\@nil}}% \edef\TList{\expandafter\@gobble\TList}% % write to file \immediate\write\ansfile{\currID\space \currX\space \currY\space \currW\space \currH\space \currA}% \advance\i by 1 \repeat \immediate\closeout\ansfile } \begin{document} \question{10}{What is $2+2$?} \ans{4} \question{5}{What is $3+5$?} \ans{8} \end{document}

An MWS is as follows. \documentclass{ctexart} \usepackage{amsmath} \makeatletter %change English parenthesis for Chinese parenthesis \def\tagform@#1{\maketag@@@{（\ignorespaces#1\unskip\@@italiccorr）}} %\newcommand{\eqref}[1]{\textup{\tagform@{\ref{#1}}}} \makeatother \begin{document} 测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字。我们有如下结论： \begin{equation} y=x^2+7x+9\text{。} \end{equation} 测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字。 \end{document} To change English parenthesis for Chinese parenthesis in equation numbers, I revised the definition of \tagform@ is amsmath. While since there are some spaces after the Chinese parenthesis, the Chinese parenthesis are not aligned to the right side. So is there anyway to fix this?

This is a follow-up to this question. I have a user-defined command which allows numbering & referencing of a single line in a starred, multiline equation environment, replacing the need to use an un-starred environment with \nonumber at the end of every other line. My first-attempt definition caused problems around ordering when using \labelcref, which the original question sucessfully resolved. The solution was the following command: \makeatletter \newcommand*\my@make@df@tag@@[1]{% \cref@old@make@df@tag@@{#1}% \let\cref@old@df@tag\df@tag \expandafter\gdef\expandafter\df@tag\expandafter{% \cref@old@df@tag \def\cref@currentlabel{% [equation][\arabic{equation}][]#1% }% }% }% \newcommand*\my@make@df@tag@@@[1]{% \cref@old@make@df@tag@@@{#1}% \let\cref@old@df@tag\df@tag \expandafter\gdef\expandafter\df@tag\expandafter{% \cref@old@df@tag \toks@\@xp{\p@equation{#1}}% \edef\cref@currentlabel{[equation][\arabic{equation}][]\the\toks@}% }% }% \newcommand{\TAG}[1]{% \refstepcounter{equation}% \begingroup \let\make@df@tag@@\my@make@df@tag@@ \let\make@df@tag@@@\my@make@df@tag@@@ \tag{\theequation}% \endgroup \label{#1}% }% \makeatother (credit to @Ulrich Diez for the solution and @Ziv for the appendix patch). This command worked perfectly with the \documentclass{article} used in the original question's MWE. Unfortunatley, I have since found that with \documentclass{book} the previous bug returns. Is there a patch to the original solution, or a new solution, that will fix this?

Since the following line: is going too close to the right margin of the page, I changed the text size of the four larger-text fractions from normal to footnotesize: $$\cos(\alpha) = \frac{\frac{1}{2\tan(36^\circ)}}{\frac{3+\sqrt{5}}{4}} = \begin{footnotesize}\frac{\raisebox{-2pt}{1}}{2\tan(36^\circ)}\bm{\cdot}\frac{\raisebox{-2pt}{4}}{3\!+\!\sqrt{5}} = \frac{\raisebox{-2pt}{4}}{2(3\!+\!\sqrt{5})\!\tan(36^\circ)}\end{footnotesize} \rightarrow m\angle\alpha = \arccos\!\raisebox{-3pt}{$\Bigl($}\!\begin{footnotesize}\frac{\raisebox{-2pt}{4}}{2(3\!+\!\sqrt{5})\!\tan(36^\circ)}\end{footnotesize}\!\raisebox{-3pt}{$\Bigr)$} \approx\!58.2825^\circ$$ But the only characters that were reduced were the numerators I lowered closer to the fraction bar. To shrink the text in the denominators, should I put them inside raisebox too and just "raise" them 0pt? Or is it better to just put the whole thing in single-$ math mode and just use \dfrac instead of \frac since it doesn't really need to be centered anyway (since it takes up the entire width)? Edit: Changing $$ $$ to \[ \] didn't help.

I am working with optex 1.17, which comes with TeXLive 2023. I am creating slides, but I am having a problem with the counter at the beginning, on the cover slide.

The following MWE is indicated to produce an accessible PDF, using lualatex in TeXLive-2026, however it produces 26 adaptable failures when checked on the axesCheck web tool. \DocumentMetadata{ lang=en-US, pdfstandard=ua-2, tagging=on, tagging-setup={math/setup={mathml-AF,mathml-SE}} } \documentclass{article} \usepackage{unicode-math} \begin{document} \title{Accessible \LaTeX} \author{I. M. Author} \date{\today} \section{Accessible Math Example} The quadratic formula is: \begin{equation} x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \end{equation} \end{document} I have tried the compilation with and without the unicode-math package and the result is the same. Removal of the equation produces a PDF that is WCAG-compliant, using the same web tool. A foo-luamml-mathml.html file is produced from the lualatex compilation of foo.tex and, when opened in a browser, appears to correctly render the equation. Nonetheless, the issue is to produce a WCAG-compliant PDF. The above MWE also follows the example shown on the LaTeX Tagging Project web page. The downloaded PDF from that example also fails the WCAG-compliance check. What am I missing or misunderstanding?

I am a little bit confused with the new babel-german v3.0, where the naming convention has a breaking change: post-1996 convention is now the default one. Is it OK to still use ngerman in current documents? Would it be different with using the new german option? Should the replacement of ngerman be german or german-de/german-germany? The documentation suggests that "it is always advisable to use a more precise option such as german-de". Thus perhaps it should be safer and more stable to use german-de instead of german. For package authors passing/detecting language options, should there be any caution with this new change? (For example, shall one need to detect the version and apply different rules separately?) Thanks so much!

Hi I tried looking for solutions online, but found nobody with this error, so I think it justifies this question. I wanted to copy the rather common template I've seen from various lecture notes and books. The template in question is the pure and applied undergrad text from the AMS monograph website: https://www.ams.org/arc/books/book-produce.html An example of the template on a chapter page I want to emulate is this one: This was taken from the template given in the link on the AMS website, once downloaded. Yet when I try do use the exact same template in Overleaf, I get pretty much the same thing, but without any page numbering: I highly doubt this is an Overleaf issue, so that's why I wanted to ask here. I would appreciate any assistance/instructions on how to turn on page numbering (from what I can see it is already enabled). Thanks.

I learned about the https://context-on-web.eu/ site just a few hours ago and am a bit confused about the results I am getting; and thought perhaps there is a version difference of some kind. I've been trying to find a solution to this question and thought I might try joining the ConTeXt mailing list and ensure the MWE works in this web tool. The strange thing is that it works fine and generates the desired result that I have not been able to get on my desktop installation. (There is one issue of the \blackrule not working in the web version.) I tried updating my desktop version which appeared to succeed but, when I tried to process the document, there was an error of mtx-context | error, no format found with name: cont-en, aborting. So, I deleted it and re-installed from the zip file. Now, the document processes but still has the old error; yet the exact same script pasted in the web tool does not error and generates the expected/desired result. My question is, What is difference between the web version and the most recent download from https://www.pragma-ade.com/install.htm? I'm running Manjaro Linux OS 64 bit.

This structural organization causes a failure in a previously working solution base on redefining \minted@cachedir.

I have been working (with some co-authors) on a review article. As of now the document is written entirely in LaTeX (OverLeaf) using my own standard preamble. The PI would now like the paper to be formatted to look like a Nature Human Behavior Article. I tried downloading Natures standard template from their website but doing the transfer across was very messy and I kept getting compliation erros. What is the best way for me to transfer over this work into the required style?

I am preparing a project that involves representing the Italian Parliament using a semicircle made of colored dots, as shown in the following image: I have tried to create something using the wheelchart package (page 19 of the manual), which allows generating similar charts. However, I am unable to automatically increase the number of dots per row. For example, in the figure there are 12 dots per row, but I would like a more customizable (for example 7 balls for every radius) and automatic solution to control this. I prefer big dots and not balls. \documentclass{article} \usepackage{tikz} \usepackage{wheelchart} \begin{document} \begin{tikzpicture} \pgfkeys{ /wheelchart, discrete, discrete pic={\shade[ball color=\WCvarB] (0,0) circle[radius=2pt];}, discrete sort=angle, discrete space at borders=false, start angle=180, total angle=180, value=\WCvarA } \wheelchart{ 120/blue/, 45/green/, 40/red/, 25/orange/, 10/purple/, 5/teal/ } \end{tikzpicture} \end{document}

I'm looking for something really simple, to remove completly the bar form the long s. I don't know how to do it properly.

There are various packages that will conveniently give extensible arrows with sub/superscripts. I'm aware of: amsmath (only for basic arrows) mathtools extarrows chemarrow You can of course do the same thing with TikZ or similar. I want something similar, but with no arrowheads at all. What's the best way to achieve that? I can do it with TikZ, but the mildly annoying part would be matching the standard arrow height and width. Should I figure out how to use the internal \arrowfill@ command in amsmath? My application is essentially marking a chain of edges connected in a graph, with various labels on the edges. Here's one attempt using a text em-dash. You can see that the em-dash isn't the same as the math-mode arrow. \documentclass[12pt]{amsart} \begin{document} \[ x \overset{\mathcal{U}}{\mathbin{\text{---}}} y \overset{\mathcal{U}}{\longrightarrow} z\] \end{document}

I am compiling a LaTeX document in VS Code using the LaTeX Workshop extension on Windows 11. My document uses: chemnum / chemstyle nomencl biblatex mhchem Originally my latexmk tool was configured with: -pdf However, this produced incorrect compound labels when using chemnum with a scheme environment (temporary labels such as TMP1, TMP2 were not replaced). Following advice from a previous question, I changed the compilation pipeline to: -pdfps, (see my previous question: VS Code LaTeX Workshop: how to configure settings.json when using both chemnum and nomencl?) This indeed fixes the chemnum labeling issue. However, now I cannot include PNG graphics. For example: \begin{figure} \centering \includegraphics[scale=0.8]{random.png} \caption{random} \label{fig:random} \end{figure} produces the error: Cannot determine size of graphic (no BoundingBox) (This also does not work with [width=0.5\textwidth] or when using a .pdf image instead of .png.). In the real document there are several PNG graphics. I would also like all PNG images to be included with a fixed scale=0.8. I found the following related question, but it is quite old, so perhaps there is a more up-to-date solution: Cannot determine size of graphic settings.json { "latex-workshop.latex.tools": [ { "name": "latexmk", "command": "latexmk", "args": [ "-synctex=1", "-interaction=nonstopmode", "-file-line-error", "-pdfps", "%DOC%" ] }, { "name": "makenomenclature", "command": "makeindex", "args": [ "%DOCFILE%.nlo", "-s", "nomencl.ist", "-o", "%DOCFILE%.nls" ] } ], "latex-workshop.latex.recipes": [ { "name": "latexmk → nomencl → latexmk", "tools": [ "latexmk", "makenomenclature", "latexmk" ] } ], "latex-workshop.latex.recipe.default": "latexmk → nomencl → latexmk", "latex-workshop.latex.autoBuild.run": "never", } aromatic-compounds.eps https://drive.google.com/file/d/1faCOOvd5xcVAF_KZqhx7vAI0Mqh7pmF6/view?usp=sharing main.tex \documentclass{article} \usepackage{geometry} \usepackage{graphicx} \usepackage[version=4]{mhchem} \usepackage{chemstyle} \usepackage{chemnum} \usepackage[backend=biber]{biblatex} \addbibresource{bib.bib} \usepackage{nomencl} \makenomenclature \begin{document} \nomenclature{A}{a} \printnomenclature \section{First} \cite{knuth1984texbook} \begin{scheme} \replacecmpd{benezen} \replacecmpd{toluene} \includegraphics[scale=0.8]{aromatic.eps} \caption{Aromatic-compounds} \label{aromatic-compounds} \end{scheme} \begin{figure} \centering \includegraphics[width=0.5\textwidth]{random.png} \caption{random} \label{fig:random} \end{figure} \refcmpd{benezen, toluene} \printbibliography \end{document} bib.bib @book{knuth1984texbook, title={The texbook}, author={Knuth, Donald Ervin and Bibby, Duane}, volume={15}, year={1984}, publisher={Addison-Wesley Reading} }

Thanks.

I'm drawing a 3D rectangle (which should be a plane, represented by the letter "H"). At the top left corner, at 'C', I want to project a $H$ in mathematical font onto the plane. I've used a cm matrix for this. The position is correct, but I've noticed that the serifs of the 'H' are parallel, despite using $H$, so it doesn't look like mathematical font. What do I need to do?

This question is a followup of a previous question of mine that David kindly answered with the following example: \documentclass{article} \usepackage{csquotes} \def\test#1{% \setbox0\hbox{#1}% \usebox{0}% \directlua{ local nn=0 for n in node.traverse_glyph(tex.box[0].head) do nn=n.char end if nn==8221 then tex.print("\string~yes") else tex.print("\string~no") end }} \begin{document} \begin{enumerate} \item \test{“Foo”} \item \test{\enquote{Bar}} \item \test{xyz} \end{enumerate} \ExplSyntaxOff \end{document} I'd like to expl3-ify this MCE and here is the first step which works nicely: \begin{filecontents*}[overwrite]{myfile.lua} function closing_double_quote(glyph) local nn=0 for n in node.traverse_glyph(glyph) do nn=n.char end if nn==8221 then tex.print("yes") else tex.print("~no") end end \end{filecontents*} \documentclass{article} \usepackage{csquotes} \ExplSyntaxOn \lua_now:n{ require('myfile') } \cs_new_protected:Nn \__mymodule_closing_double_quote:n { \setbox0\hbox{#1} \usebox{0} : \c_space_tl \lua_now:n{ tex.write(closing_double_quote(tex.box[0].head)) } } \begin{document} \begin{enumerate} \item \__mymodule_closing_double_quote:n {“Foo”} \item \__mymodule_closing_double_quote:n {\enquote{Bar}} \item \__mymodule_closing_double_quote:n {xyz} \end{enumerate} \end{document} What remains is: \setbox0\hbox{#1} \usebox{0} that could be expl3-ified as follows: \hbox_set:Nn \l_tmpa_box { #1 } \box_use:N \l_tmpa_box But what would be the equivalent of box[0] in the Lua code: tex.write(closing_double_quote(tex.box[0].head))

Is it possible to set the vertical space between two subtables as in Table 2 in the following MWE, but using something more "automatic" than setting a \vspace manually? \documentclass{book} \usepackage{subcaption} \subcaptionsetup[table]{position=top} \begin{document} \begin{table}[ht]\centering \caption{Table caption} \begin{subtable}{\linewidth}\centering \caption{First subtable caption} \begin{tabular}{cc} \hline a & b \\ c & d \\ \hline \end{tabular} \end{subtable} \begin{subtable}{\linewidth}\centering \caption{Second subtable caption} \begin{tabular}{cc} \hline e & f \\ g & h \\ \hline \end{tabular} \end{subtable} \end{table} \begin{table}[ht]\centering \caption{Table caption} \begin{subtable}{\linewidth}\centering \caption{First subtable caption} \begin{tabular}{cc} \hline a & b \\ c & d \\ \hline \end{tabular} \end{subtable}\vspace{10pt} \begin{subtable}{\linewidth}\centering \caption{Second subtable caption} \begin{tabular}{cc} \hline e & f \\ g & h \\ \hline \end{tabular} \end{subtable} \end{table} \end{document} Maybe this is a trivial question, but I found only the \vspace (or similar) answers.

I'm trying to use \definelistalternative to alter the way a part is displayed in the Table of Contents. That appears to be working but I'm having trouble with the conversion of the \currentlistentrynumber to the text provided in the \defineconversion[Parts] line in this example. I know that the \convertnumber{Parts}{...} works because it is used in the first chapter using hard-coded integers and it returns First, Second, or Third. But the \convertnumber{Parts}{\currentlistentrynumber} throws an error (strangely at the numberalign=flushright under the chapter level of setuplist); and I assume that is because \currentlistentrynumber is not treated as its integer value. I tried passing it to a custom command \ConvertPartNbr declared in this example, but the error is the same. How can I get to the value of \currentlistentrynumber in order to convert it? It is under \startsetups [PartsTOCsu], at line %{Part \convertnumber{Parts}{\currentlistentrynumber}{.}}% currently commented out. Thank you. Also {Part \convertnumber{Parts}{\currentlistentrynumber}} and {Part \expandafter\convertnumber{Parts}{\currentlistentrynumber}} both throw the error of csname overload > warning, protection level 3, control sequence 'P', properties 'permanent', file './mwe4.tex', line 6 csname overload > warning, protection level 3, control sequence 'convertnumber', properties 'permanent', file './mwe4.tex', line 6 !

As a follow-up to a previous question, how can I prevent TikZ from cutting off the edge of the path if the edge of the object goes beyond the edge of the fading pattern? Here is a minimal working example: \documentclass{article} \usepackage[svgnames]{xcolor} \usepackage{tikz} \usetikzlibrary{fadings} \begin{document} \begin{tikzpicture} \begin{scope} \path [scope fading=east] (1,1) rectangle (3,3); \draw [FireBrick,very thick] (0,0) rectangle (2,2); \end{scope} \draw [dotted] (1,1) rectangle (3,3); \begin{scope}[yshift=-4cm] \path [scope fading=east] (1,1) rectangle (3,3); \draw [Gray,very thick] (-1,-1) rectangle (2,2); \end{scope} \draw [yshift=-4cm,dotted] (1,1) rectangle (3,3); \begin{scope}[yshift=-4cm,xshift=5cm] \path [scope fading=east] (1,-1) rectangle (3,3); \draw [Gray,very thick] (-1,-1) rectangle (2,2); \end{scope} \draw [Gray,very thick,yshift=-4cm,xshift=5cm] (0,2) -- (-1,2) -- (-1,-1) -- (0,-1); \end{tikzpicture} \end{document} which produces, in XPDF, Note that the red one works fine, because the edge of the fading (which extends about 25% beyond the edge of the object) is still 100% transparent there, but the gray one does not work because it extends past the edge of the fading. It should look like the one on the lower right, at least on the left-hand side of the square. Note that it would also be an issue for fadings that don't fade all the way out going off the right of the fading, or for very large radial fadings that fade to transparent well before the edge of the object being faded. If the paths were filled, I could simply fill the left part of the pattern with the solid color and clip without having to re-draw it, but if it's just a draw shading, part of it gets cut off and I don't know how to get it back short of drawing it again. Note: some PDF viewers (including my usual ones, Evince and Papers), do not display any of these images correctly, because they don't handle faded drawn paths correctly. This is a viewer problem, but XPDF seems to do better.

A manuscript I am typesetting to be published includes a long, wide table that I think would be best formatted as a multi-page longtable environment inside a landscape environment. The printed book will use \marginnote to give the manuscript page number. This works fine, except on the landscape page where the \marginnote overlaps the text. Here is a MWE showing the problem (which manifests without the longtable): \documentclass[a4paper,oneside]{book} \usepackage{marginnote} \usepackage{pdflscape} \usepackage{lipsum} \newcommand\pg{\marginnote{\textbf{Page}}} \begin{document} \pg \lipsum[1] \lipsum[2][1-4] \pg \lipsum[2][5-] \begin{landscape} \pg \lipsum[3] \end{landscape} \end{document} Is there any way to make a \marginnote work inside a landscape environment? The marginnote manual says: The marginnote package needs to know the real width of the text area to find the right margin. While some environments (e.g., of the framed package) change \textwidth, marginnote defines its own text width macro. If you change the text area after \begin{document} you should add \edef\marginnotetextwidth{\the\textwidth} after changing the text area. You may want to do this globally using \xdef instead of \edef. Most users will never need to change \marginnotetextwidth. I've tried adding this line (both with \edef and with \xdef) inside the landscape environment, but it makes no difference. Setting it to \the\linewidth shifts the \marginnote somewhat to the right, but it still overlaps the text. Hardcoding a \marginnotetextwidth of about 332mm inside the landscape environment broadly works in this test example, but I don't understand why, as this is substantially larger than the dimensions of the A4 paper (210mm × 297mm). In cases it matters, I'm using xelatex, but it also happens with pdflatex.

My goal is to have zero-padded page numbers in the footer and in the table of contents. I use the code from this answer. However, it breaks with the hyperref package, only when the total page number has one digit, with the following error: test.tex: error: 86: Use of \??? doesn't match its definition. \newpage. I know that the padding is not needed in this case, but I would like the code to be more robust and also to understand why it breaks in that case. Here is a minimal working example. You can comment out/in \manypages to toggle between the code that breaks or not. \documentclass{article} \usepackage{lastpage} \usepackage{fancyhdr} \usepackage{hyperref} \hypersetup{ colorlinks = true, allcolors = blue } % From https://tex.stackexchange.com/a/730655/228589 \ExplSyntaxOn \NewDocumentCommand{\paddedcounter}{m} { \AtBeginDocument { \cs_if_exist:cF {maxdigits#1} { \cs_gset:cpn {maxdigits#1} {8} } } \AtEndDocument { \iow_now:ce {@mainaux} { \token_to_str:N \maxdigits{#1}{\fp_eval:n{logb(\value{#1}+0.1)+1}} } } \cs_gset:cpn {the#1} { \padded{#1} } } \NewDocumentCommand{\maxdigits}{mm} { \cs_gset:cpn {maxdigits#1}{#2} } \NewExpandableDocumentCommand{\padded}{m} { \prg_replicate:nn { \use:c { maxdigits#1 } - \tl_count:e { \arabic{#1} } } { 0 } \arabic{#1} } \ExplSyntaxOff \paddedcounter{page} \pagestyle{fancy} \fancyhead{} \renewcommand{\headrulewidth}{0pt} \fancyfoot[C]{\thepage\ / \pageref*{LastPage}} \newcommand{\manypages} { \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage \section{Some section} \newpage } \begin{document} \thispagestyle{fancy} \begin{center} {\Huge Some title} \end{center} \tableofcontents \newpage \manypages \end{document}

I want to colour the harakat (diacritics) of a text in Pashto. I use Luatex, and I want to switch this function on and off.

I am designing a square (or “squarish” actually) map protractor in TikZ. So far, I have managed to draw the degree ticks along the four sides by clipping radial lines between two closed paths using the even odd rule like I saw in this answer. The ticks are generated in a \foreach loop. To avoid drawing long ticks on top of short ones, I separated them into two loops using a conditional test. I am not sure whether this separation is actually necessary for correct SVG export/printing, but that is how I implemented it. Below is a MWE: \documentclass[tikz]{standalone} %,convert={outfile=\main.svg} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usetikzlibrary{intersections, pgfplots.fillbetween} \pgfdeclarelayer{pre main} \pgfdeclarelayer{main} \pgfsetlayers{pre main, main} \usetikzlibrary{shapes} \begin{document} %all of this is needed to easily clip between two closed paths using even odd rule \makeatletter \def\@appendnamedsoftpath#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\expandafter\expandafter\def\expandafter\expandafter\expandafter\@temppatha\expandafter\expandafter\expandafter{\expandafter\@temppatha\@temppathb}% \pgfsyssoftpath@setcurrentpath\@temppatha } \def\@appendnamedpathforactions#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\def\expandafter\@temppatha\expandafter{\csname @temppatha\expandafter\endcsname\@temppathb}% \let\tikz@actions@path\@temppatha } \tikzset{ use path for main/.code={% \tikz@addmode{% \expandafter\pgfsyssoftpath@setcurrentpath\csname tikz@intersect@path@name@#1\endcsname }% }, append path for main/.code={% \tikz@addmode{% \@appendnamedsoftpath{#1}% }% }, use path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions\expandafter\let\expandafter\tikz@actions@path\csname tikz@intersect@path@name@#1\endcsname}% }, append path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions \@appendnamedpathforactions{#1}}% }, use path/.style={% use path for main=#1, use path for actions=#1, }, append path/.style={% append path for main=#1, append path for actions=#1 } } \makeatother \begin{tikzpicture} \pgfmathsetmacro\bigside{7} \pgfmathsetmacro\smallsidedelta{0.5} %cuts \draw[rounded corners=12pt, name path=outside] (0,0) rectangle (\bigside,\bigside); \draw[dotted, rounded corners=12pt, name path=inside] (\smallsidedelta,\smallsidedelta) rectangle (\bigside-\smallsidedelta,\bigside-\smallsidedelta); %remove before cutting or printign.

When numbers get big, they don't have enough space to fit unless the labels become too small to read (actual printing size of the protractor will be something like 7x7 or 8x8cm). So they need to be shifted in such a way that they fit. 355 in the provided image is a clear example of what I mean. I can consider shifting them radially as well, but they need to stay to the outside of the dotted line, which I can make a little smaller. I really don't know where to start and didn't manage to find anything online. Thank you for your time!
