How do I get alignment in systeme when using fractions? \documentclass{book} \usepackage{amsmath} \usepackage{systeme} \begin{document} \[ \systeme{y+z=72,x+\tfrac{2}{3}y+\tfrac{1}{2}z=72} \] \end{document} I could not find an example with fractions in the French documentation of systeme. I tried brackets, but it did not help. \systeme{y+z=72,x+{\tfrac{2}{3}}y+{\tfrac{1}{2}}z=72}

I want to generate a test.hnt file from the following test.tex file: \documentclass{scrartcl} % article works \usepackage{pgfplots} % removing this works \begin{document} Hello World! \end{document} When I run hilatex test.tex I get the following error message about exceeded TeX capacity: ! TeX capacity exceeded, sorry [hash size=45000]. \pgfkeyslet ...ter \let \csname pgfk@#1\endcsname #2 l.4831 } The test.log file contains the following information about the issue: ! TeX capacity exceeded, sorry [hash size=45000]. \pgfkeyslet ...ter \let \csname pgfk@#1\endcsname #2 l.4831 } If you really absolutely need more capacity, you can ask a wizard to enlarge me. Here is how much of TeX's memory you used: 22130 strings out of 475903 562725 string characters out of 5796992 1256262 words of memory out of 5000001 45000 multiletter control sequences out of 45000 559137 words of font info for 37 fonts, out of 8000000 for 255 475 hyphenation exceptions out of 8191 108i,7n,107p,10900b,609s stack positions out of 5000i,500n,10000p,2000000b,100000s This issue does not occur when I use article instead of scrartcl. It does also not occur when I remove pgfplots. (However, both are required in my project.) How can I avoid this issue?

Some LaTeX packages provide nice functionality to compute the optimal margins for a given page size, font and font size. I.e. KOMA-Script does offer the package option DIV=calc and \KOMAoptions{DIV=last}. This, however, leads to rather large margins, if A4 paper is used. I was hence wondering if we can even go one step further and let LaTex also compute the "optimal" paper size (if such a thing exists, but I'm certain that typographers have opinions on this) based on font/font size and the number of columns we use. Of course, this means that if we print the output, we need to cut/trim the paper accordingly.

When drawing a double line, an ugly thin connection between the ends is drawn, as you can see in the image. Is there a way to remove it without manually drawing white over it? Shortening the arrow does not do the job. I am new to Tikz. \documentclass[border=10pt]{standalone} \usepackage{tikz} \begin{document} % Source - https://tex.stackexchange.com/q/759221 % Posted by return true % Retrieved 2026-02-04, License - CC BY-SA 4.0 \begin{tikzpicture} \draw[line width = 2mm, double distance = 4mm, line cap=butt] (0,0) -- (10cm,10cm); \end{tikzpicture} \end{document}

I am writing a document that can be read and shared freely, but not modified one bit. I want it to "break" once it's sha256 key differs or at least, indicate that it has been changed over time. I have come across this question: It is possible to lock up pdf? where it says it is a duplicate of: Digital signature, where the solution is this link: https://answers.onstartups.com/questions/41625/protecting-works-for-being-able-to-prove-later-ive-done-this-on-this-date that seems broken. I am also aware of digsig which seems more like adding the image of a signature rather than actually generating crytographic keys, etc. I see other stuff like using qpdf and secondary software solution. I wondered if it were possible to do this natively using lualatex? I am using Linux Mint and LuaHBTeX, Version 1.22.0 (TeX Live 2025) I am sorry I have no working example to offer because I'm not even sure where to start. I apologise in advance for my rule-breaking.

I’m dissatisfied with the formal letter templates on Overleaf and, frankly, with most of the tutorials I’ve found online. I genuinely enjoy written correspondence, and I want my formal letter format to look truly professional. I’ve created my own template for a confidential formal letter based on what I remember from past training, but it’s been a long time. I’d appreciate feedback to help ensure the format looks polished and professional. I did not know what tag to use, so I used layout. Feel free to correct that if you are more familiar this concept than I. \documentclass{article} \usepackage[margin = 1in]{geometry} \usepackage{fontspec,microtype,lipsum}\setmainfont{Carlito} \setlength{\parskip}{0pt} \setlength{\parindent}{0pt} \begin{document} My Name\\ My address\\ My city and postal code\par \vspace{\baselineskip} \today\par \vspace{2\baselineskip} \textbf{CONFIDENTIAL}\par \vspace{2\baselineskip} Name of recipient\\ Their title\\ Their company\\ Their address\\ Their city and postal code\par \vspace{\baselineskip} Dear Name of recipient,\par \vspace{\baselineskip} \lipsum[1]\par \vspace{\baselineskip} \lipsum[2]\par \vspace{\baselineskip} Sincerely,\\ My name \end{document}

In my current (math) font configuration, symbols are taken from different fonts according to need, which usually looks nice but sometimes may produce terrible result due to mixture. For example, for \widehat, \widetilde and \check: It would seem that they are not properly centered for certain letters (B, C, E, F, G, H, K, M, N, etc.), and the width is also not quite uniform, compared with visual expectation. I know that there exists lua code that can edit the kerning of math characters, for example, space between letters, space between letter and subscripts/superscripts, etc. Could the same kind of code also modify/redefine the center, the baseline, the character width, etc.? Here is the lua code I adopted some time ago from this answer that can modify the kerning between letter and scripts. For modifying kerning between symbols, one could see, e.g., this answer. (Unfortunately I do not quite understand how these code work, for example if I change topright to top in wish to change the relative position for hats and tildes, it actually does nothing effective, so this is clearly not the right keyword/switch to use...) Also, I wonder if these lua code can be combined, for example, if I simply put the code for adjusting kerning between symbols/letters inside the code below (within local mathkerns = ...), then nothing effective happens... \directlua { local mathkerns = { ["Asana-Math"] = { [0x1D439] = {% F topright = { {height=0,kern=30}, }, }, [0x1D443] = {% P topright = { {height=0,kern=90}, }, }, [0x1D447] = {% T bottomright = { {height=0,kern=-120}, }, }, [0x1D449] = {% V bottomright = { {height=0,kern=-120}, }, }, [0x1D44A] = {% W bottomright = { {height=0,kern=-30}, }, }, [0x1D453] = {% f bottomright = { {height=0,kern=-135}, }, }, [0x1D44F] = {% b topright = { {height=0,kern=75}, }, }, }, } local function initmathkern(tfmdata) local values = mathkerns[tfmdata.properties.psname] if not values then return end for cp, value in next, values do local tcp = type(cp) if tcp == 'string' then cp = tfmdata.resources.unicodes[cp] end local char = tfmdata.characters[cp] if char then local mathkern = char.mathkerns if not mathkern then mathkern = {} char.mathkerns = mathkern end for corner, v in next, value do mathkern[corner] = v end end end end fonts.constructors.newfeatures'otf'.register{ name = 'mathkern', description = 'Overwrite mathkern values', initializers = { base = initmathkern, }, } } Here is a MWE. \documentclass{article} \usepackage{kpfonts-otf} \usepackage{unicode-math} \setmathfont{KpMath-Sans.otf}[range={\check}] \setmathfont[RawFeature=mathkern]{Asana-Math.otf}[range={it/{Latin,latin},bfit/{Latin,latin},up/num,bfup/num}] \begin{document} \[ \check{A} \check{B} \check{C} \check{D} \check{E} \check{F} \check{G} \check{H} \check{I} \check{J} \check{K} \check{L} \check{M} \check{N} \check{O} \check{P} \check{Q} \check{R} \check{S} \check{T} \check{U} \check{V} \check{W} \check{X} \check{Y} \check{Z} \] \[ \widehat{A} \widehat{B} \widehat{C} \widehat{D} \widehat{E} \widehat{F} \widehat{G} \widehat{H} \widehat{I} \widehat{J} \widehat{K} \widehat{L} \widehat{M} \widehat{N} \widehat{O} \widehat{P} \widehat{Q} \widehat{R} \widehat{S} \widehat{T} \widehat{U} \widehat{V} \widehat{W} \widehat{X} \widehat{Y} \widehat{Z} \] \[ \widetilde{A} \widetilde{B} \widetilde{C} \widetilde{D} \widetilde{E} \widetilde{F} \widetilde{G} \widetilde{H} \widetilde{I} \widetilde{J} \widetilde{K} \widetilde{L} \widetilde{M} \widetilde{N} \widetilde{O} \widetilde{P} \widetilde{Q} \widetilde{R} \widetilde{S} \widetilde{T} \widetilde{U} \widetilde{V} \widetilde{W} \widetilde{X} \widetilde{Y} \widetilde{Z} \] \end{document}

I would like to produce a Ȟ ("H" with caron accent) in math mode, specifically, for \mathsf. (This is an uncommon notation used for Čech cohomology in a book.) Perhaps this would be easy for pdfLaTeX. However, when using LuaLaTeX, and when this character is not already provided in the font, I can only get very strange output: Is there some way to mimic this caron accent in this situation? More generally, how can one apply this accent to general math symbols? (In the same book, this accent seems to be used to represent the dual objects, e.g., V with caron accent instead of V^{\vee}, possibly to save some space...) (I tried \check, but it looks different and cannot be properly aligned...) \documentclass{article} \usepackage{kpfonts-otf} \usepackage{unicode-math} \begin{document} Ȟ % \v{H} \( \mathsf{Ȟ} \) \( \mathsf{\v{H}} \) \( \check{\mathsf{H}} \) \end{document}

I get that the screen mode basically adds the RGB values. Is it possible to take the average of the values instead, so that colors don't get lighter? Opacity trick doesn't seem to work because I want full opacity where the images don't overlap.

I am trying to use \setkomafont to set the font of titles and headings, but when I try to use a custom font with \fontspec or \fontfamily, it overrides \bfseries instead of applying them both. So, when I use the command below, it only applies Roboto and the font size: \setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\bfseries\selectfont} Other similar commands that I have tried but didn't work: \setkomafont{title}{\fontfamily{Roboto}\fontsize{20}{24}\bfseries\selectfont} % \setkomafont{title}{\fontfamily{Helvetica}\fontsize{20}{24}\bfseries\selectfont} % \setkomafont{title}{\fontfamily{Montserrat}\fontsize{20}{24}\bfseries\selectfont} % etc, etc When I use each of these commands alone, it also works fine \setkomafont{title}{\fontsize{20}{24}\bfseries\selectfont} % and \setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\selectfont} As expected, the first command applies the bold font and the second command applies the Roboto font. A non-exhaustive list of l tried trying to fix this problem (we're just going to use \fontspec{Roboto} in all of them for simplicities sake I've gone insane enough. Just know that I tried many fonts in both koma-script and fontspec): \setkomafont{title}{{\fontspec{Roboto}}\fontsize{20}{24}\bfseries\selectfont} \setkomafont{title}{{\fontspec{Roboto}}\fontsize{20}{24}\bfseries\selectfont} % \setkomafont{title}{\fontspec{Roboto}{\fontsize{20}{24}\bfseries\selectfont}} % \setkomafont{title}{\fontsize{20}{24}\bfseries\selectfont} \addtokomafont{title}{\fontspec{Roboto}} % \setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\bfseries\selectfont} \addtokomafont{title}{\bfseries} % This one got rid of the font and made it bold instead XDDDDDDDDDDD I also went in Windows Shell to look at the luaotfload-tool package and force it to update after looking through the fontspec manual. I did not find anything being discussed in the KOMA-script manual or the The Not So Short Introduction to LaTeX, but I didn't do a thorough search.

I have been looking at Sockets recently, and have some questions on their behaviour. I have had a look at Practical guidelines for using sockets and Example of using plugs and sockets, as well as ltsockets-doc, and I have played with sockets in a document (mostly for testing). I would like to know if the behaviour I am seeing is expected (and will continue to work), or if it is a factor of how it is (currently) implemented, and I shouldn't rely on it. \documentclass{article} \NewSocket{enkorvaks/format-i}{1} \NewSocket{enkorvaks/format-ii}{1} \NewSocketPlug{enkorvaks/format-i}{formatibold}{Format 1: \textbf{#1}} \NewSocketPlug{enkorvaks/format-ii}{formatiitt}{Format 2: \texttt{#1}} \AssignSocketPlug{enkorvaks/format-i}{formatibold} \AssignSocketPlug{enkorvaks/format-ii}{formatiitt} \ExplSyntaxOn \tl_new:N \l_enkorvaks_formatchoice_tl \tl_set:Nn \l_enkorvaks_formatchoice_tl {format-i} \NewDocumentCommand{\sockettesting}{m}{ \UseSocket{enkorvaks/\l_enkorvaks_formatchoice_tl}{#1} } \NewDocumentCommand{\formatbold}{}{ \tl_set:Nn \l_enkorvaks_formatchoice_tl {format-i} } \NewDocumentCommand{\formattt}{}{ \tl_set:Nn \l_enkorvaks_formatchoice_tl {format-ii} } \ExplSyntaxOff \begin{document} Socket Test: \sockettesting{This should be bold (format 1)} \formattt{} Socket Test: \sockettesting{This should be tt (format 2)} \formatbold{} Socket Test: \sockettesting{This should be bold (format 1) again} \end{document} (yes, this is a trivial use, and doesn't need sockets, but this is an example only) In short, the question is: Can I use token lists (or \newcommands, I guess) as part of the \UseSocket and expect it to work into the future?

The APA 7 standard for student papers requires tables and figures to be moved to the end of the document. I have several small tables in my document and they each appear at the end of the document on a separate page. This seems silly as one page could easily fit all my tables. Is this intended behaviour to accommodate some APA requirement I am unaware of? If not how might I go about modifying my script so that tables and figures are compiled on the same page if they fit? Below is a minimal working example to show the issue. \documentclass[stu]{apa7} \usepackage{lipsum} \title{Assignment Title} \begin{document} \maketitle \lipsum \begin{table} \caption{first small table} \begin{tabular}{lcccc} \toprule &A1&A2&A3&A4\\ \midrule B1&25&159&27&11\\ B2&67&117&75&9\\ \bottomrule \end{tabular} \end{table} \begin{table} \caption{second small table} \begin{tabular}{lcccc} \toprule &A1&A2&A3&A4\\ \midrule B1&25&159&27&11\\ B2&67&117&75&9\\ \bottomrule \end{tabular} \end{table} \end{document}

In my document I collect data and process it in a macro. The macro has various sections of the table (here shown section staff and costs). Each section has a "header row" I want to specially highlight. The main part of the section is collected using a DTLforeach-run (here just some hard coded numbers, I omitted the part to sum up e.g. the costs, too). I would like to visually show the separation of the staff and costs section using a horizontal line. But \SetHline{-}{red,0.5pt} is not working and \SetCell{font=\footnotesize\bfseries,halign=l} breaks to whole document. \documentclass{scrartcl} \usepackage{xcolor} \usepackage{tabularray} \UseTblrLibrary{siunitx} \UseTblrLibrary{functional} \ExplSyntaxOn \tl_new:N \l__tmp_body_staff_tl \tl_new:N \l__tmp_body_costs_tl \NewDocumentCommand{\requestedFundingTable}{o}{ Table~ #1 :\par \tl_clear:N \l__tmp_body_staff_tl \tl_clear:N \l__tmp_body_costs_tl \tl_put_right:Ne \l__tmp_body_staff_tl { \SetRow{red!20} % not working % \SetCell{font=\footnotesize\bfseries,halign=l} % fatal error Staff & Qty & Sum \\ } \tl_put_right:Ne \l__tmp_body_costs_tl { \SetHline{-}{red,0.5pt} % not working \SetRow{red!20} % not working % \SetCell{font=\footnotesize\bfseries,halign=l} % fatal error Direct~ Costs & \SetCell[c=2]{c} Sum & \\ } % further processing in between \tl_put_right:Ne \l__tmp_body_staff_tl { category & 12 & 123 \\ } \tl_put_right:Ne \l__tmp_body_costs_tl { category & \SetCell[c=2]{c} 1234 & \\ } \begin{tblr}[ long, expand= \l__tmp_body_staff_tl \l__tmp_body_costs_tl, ]{ colspec = { *{1}{X[4,m]} *{2}{X[r, si={table-format=4}]} }, row{1,2} = {guard}, } CATEGORY & \SetCell[c=2]{c} year & \\ \tl_use:N \l__tmp_body_staff_tl % \SetHline{1-10}{red,1pt} % would work here \tl_use:N \l__tmp_body_costs_tl \end{tblr} } \ExplSyntaxOff \begin{document} \requestedFundingTable[A1] \requestedFundingTable[A2] \end{document}

I'm using the metre package which unfortunately makes it impossible to use amsmath because of some conflict. I don't really know where the incompatibility lies but this has never before been a problem because I never needed any of the amsmath commands while using metre in the same document. Now, however, I need an environment like \begin{align} ... \end{align}. Is there any way that I can use this in spite of the conflict? What I need is to be able to write sequences like these: where the vertical lines are aligned with each other. A minimal not-working example is below for how I would do it if there was no conflict. I know that the use of \text within the align-environment is a bit crude, but I don't really mind that. \documentclass{article} \usepackage[en]{metre} \usepackage{amsmath} \begin{document} \begin{align*} \text{\metra{\m\a\m\a\m\a\m\a\C}} &\text{\metra{\m\bb\C\m\a\m\b\bm}} \\ \text{\metra{\a\m\a\m\a\C}} & \text{\metra{\m\bb\C\m\a\m\b\bm}} \end{align*} \end{document} Here is an actual MWE for the symbols themselves but not aligned how I would want them to be aligned: \documentclass{article} \usepackage[en]{metre} \begin{document} \metra{\m\a\m\a\m\a\m\a\C\m\bb\C\m\a\m\b\bm} \\ \metra{\a\m\a\m\a\C\m\bb\C\m\a\m\b\bm} \end{document} I am aware that for this MWE it would be sufficient to just make everything flush right, but this is insufficient in other contexts like this one: Thanks in advance for any help!

I am using the package metre. It has the environment \metra{} used for typesetting latin (and greek) metre notation. This environment has almost all the special characters I need, except one: I need a character that looks somewhat like a fermata 𝄐 but preferrably in the same style as the other metrical symbols. This could, I believe, be achieved by simply taking the character breve that is produced by \documentclass{article} \usepackage[en]{metre} \begin{document} \metra{\a\m\b\bm} \end{document} and have it flipped upside down and a dot put underneath. In a book, this is what it looks like: It's the last symbol of each of the lines in the box. Does anyone know how this could be achieved? I even tried contacting the package's creator but his email address does not seem to exist anymore. My MWE produces the symbols in this picture (the ones inside the brackets): Thanks in advance!

Example: \documentclass[a4paper]{article} \overfullrule=10mm \usepackage{tabularx} \begin{document} %\maketitle This document is for experimenting around \texttt{tabularx}. \begin{tabularx}{\linewidth}{|p{5cm}p{5cm}}%p{5cm} %\begin{minipage}{\linewidth} \begin{tabular*}{\linewidth}{|p{2cm}}% long text to be \newline long text to be \newline long text to be \newline long text to be \newline long text to be \newline % \the\hsize % \the\linewidth % \the\textwidth long text to be \end{tabular*} %\end{minipage} & %\begin{tabularx}{0.25\linewidth}{|X}% 2nd %\end{tabularx} \end{tabularx} \end{document} The resulting PD shows two columns but vertical alignment seems to be centered. Because of the p specification I expected top level. What is strange, if I remove the inner tabular environment, keeping the content, then the alignment is correct again. What happened and how to recover? You know, this is just a MWE; of course I need some inner tabular.

Example: \documentclass[a4paper]{article} \overfullrule=10mm \usepackage{tabularx} \begin{document} This document is for experimenting around \texttt{tabularx}. \begin{tabularx}{\linewidth}{|XX}%p{5cm} \begin{minipage}{\linewidth} \begin{tabularx}{\linewidth}{|X}% long text to be \newline long text to be \newline long text to be \newline long text to be \newline long text to be \newline % \the\hsize % \the\linewidth % \the\textwidth long text to be \end{tabularx} \end{minipage} & %\begin{tabularx}{0.25\linewidth}{|X}% 2nd %\end{tabularx} \end{tabularx} \end{document} results in: !

If I replace the inner tabularx by tabular (dropping \linewidth and changing X) it works. I would even like to use without minipage, but that it does not work with minipage, it means that minipage encapsulation is not very strict. I will have a look I think I remember an example where nested tabularx worked.

(Sorry again for the vague title of this question (which is a follow-up of another question of mine), I can't think of a more appropriate one.) Suppose I'd like to augment the key set of keytheorems with a Title key which isn't exactly an alias of its title (or its alias name) key but which makes uppercase the first character of its value before passing it to keytheorems' title (or name). In the following MCE, I rely for this on an auxiliary token list which, unfortunately, is not limited to the definition of each defined theorem: only the last value it took is used each time one of the defined theorems is used, so instead of: Abc 1.
