Hot

I am trying to achieve something like this in TikZ: The black path should go straight up and the red one should go down bent to the right, both must look like a coil. I have tried to do this using bezier curves and arcs, but the coil decoration of the bent path looks very strange, it's pointy in some parts. What am I doing wrong? MWE: \documentclass{article} \usepackage{xcolor} \usepackage{tikz} \usetikzlibrary{decorations.pathmorphing} \begin{document} \begin{tikzpicture} \draw[-latex, decorate, decoration = {coil, aspect = 1.2}, color = red] (0,2) arc (90:-90:1); \draw[-latex, decorate, decoration = {coil, aspect = 1.2}] (0,0) -- (0,2); \draw[-latex, decorate, decoration = {coil, aspect = 1.2}] (3,0) -- (3,2); \draw[-latex, decorate, decoration = {coil, aspect = 1.2}, color = red] (3,2) .. controls (4,2) and (4,0) .. (3,0); \end{tikzpicture} \end{document}

Now I tried to solve this for several hours/days now, even with LLM support, but could not find a solution that just works even though the problem seems simple enough: For my CV, I wanted to have sections in small-caps, and the font I use on Overleaf (SourceSansPro) does support this. The rendered PDF looks great, exactly what I had in mind. However, with ATS software automatically screening CVs, They need to survive the pdf-to-text (poppler) conversion. I test this on Ubuntu with the simple pdftotext -layout shell command. With my simple and ordered article, this works fine out of the box. I used accsupp to hide some symbols and the footer, which also works good. However, the smallcaps are nasty. Out of the box ordering is fine, but they get converted to f.e. "EXPERiENCE", that is all caps but ONLY the letter i as lowercase. This simply does not look professional (or should I say "PROFESSiONAL"), and might influence some person's or machine's judgement when presented with the extracted text. My goal is to get either "Experience" or "EXPERIENCE", as long as it is consistent. You will not believe how many hours I tried to fix this, my best tries: Use accsupp again. A fix that will not work for copy-paste, but atleast for pdftotext (which would be fine enough for me). But this messes with the reading order: The sections may appear after the block text at time. fake smallcaps. The spacing between the larger initial and the rest gets converted to a space though, so you will get something like "E XPERIENCE". manually tweaking a capital I down to look like smallcaps i. I've had it as far as to get they height and width perfectly, but gave up after finding out the distance to next and previous letters needs adjustment as well. I fear adding hspace or kern will again be interpreted as space, and hope someone here has a better nonhack solution anyway. I would also be interested (optional) why this was implemented in Latex this way. But first and foremost: Does anyone know a clean solution to this? % # minimal example for my CV \documentclass[10pt,a4paper]{article} % XeLaTeX \usepackage{fontspec} \newfontfamily\sectionfont{SourceSansPro}[ Extension=.otf, UprightFont=*-Light, Letters=SmallCaps] \usepackage{lipsum} \usepackage[explicit]{titlesec} \titleformat{\section}[block]{\sectionfont\LARGE}{}{0em}{ \addfontfeatures{LetterSpace=1.8}\spaceskip=1.35\fontdimen2\font% #1% \hspace{0.55em}\leaders\hbox{\rule[0.513em]{0.077ex}{0.077ex}\hskip 2.1pt}\hfill\null}% dotted line \titlespacing*{\section}{0pt}{0.85em}{0.50em} \begin{document} \section{Experience} \lipsum[1] \section{Activities} \lipsum[2] \end{document}

Although you can define \mathsfit or \mathsfbfit using \DeclareMathAlphabet, it \mathsfit doesn't work within \bm or \boldsymbol.

I would like to have enumext and enumext* share a counter in my tagged pdf. The best I've found so far is to use start={1+\value{enumXi}} or start={1+\value{enumXvii}}, depending on which environment came before. But that requires that I track which environment came before.

I have noticed that after a recent TexLive update, the behaviour of the sansmath package has changed. The two example below illustrate: The instructions: \documentclass{article} \usepackage{sansmath} \begin{document} \sansmath This is normal text. \begin{tabular}{ll} One & Two \\ \end{tabular} and the rest of the document follows. \end{document} result in the contents of the tabular environment to be italized (as if it is in a math environment). This is new, unexpected behaviour. If the \sansmath is omitted, then the content of the tabular environment is not placed in italics: \documentclass{article} \usepackage{sansmath} \begin{document} This is normal text. \begin{tabular}{ll} One & Two \\ \end{tabular} and the rest of the document follows. \end{document} I will greatly appreciate any advice on how to revert to the behaviour of \sansmath to what is expected: it impacts only math environments.

I accidentally pressed some unknown key combination in Overleaf, and since then I can no longer type numbers or Chinese punctuation marks (e.g. 123, ；, 。, ‘) in one specific .tex file. English letters still work normally. Environment: Windows 11 Chrome Chinese IME What I have checked: The same file can be edited normally on another collaborator's computer. If I copy the file to a local TeX editor, numbers and Chinese punctuation can be entered normally. The problem only occurs in Overleaf on my computer. Has anyone seen a similar issue or knows which editor shortcut/keybinding might have been triggered accidentally?

I am trying to reproduce the following header style for exercises in a LaTeX document using TikZ. The header consists of two rectangles side by side: A blue rectangle on the left with rounded corners An orange rectangle on the right with rounded corners Each rectangle has a circle on its inner edge (right edge of the blue one, left edge of the orange one). The two circles overlap and their intersection should appear as a white lens-shaped area (vesica piscis effect), as if the circles were drawn on top of the rectangles and cut through both. The exercise number is placed inside the blue circle area, and the word "Exercice" appears in the orange rectangle. I tried using even odd rule and \clip with \begin{scope} but I cannot get the intersection to look clean — either one circle hides the other, or the background rectangle shows through.

Packages on CTAN are tagged according to their licence; this information is displayed on each package's page along with other basic metadata such as its name, version, maintainer, and topics. I know that I can browse or search for all packages assigned to a given topic using the topics index or using the extended search form. Is there any similarly easy way of finding all CTAN packages with a given licence? Here's what I've tried so far: I checked the master licence list, but if I click on one of the licences in the list, the page I'm taken to gives me only basic information about the licence and (in some cases) some statistics about the number of packages that use that licence. I checked the extended search form form. It doesn't have a dedicated field for the licence. If I do search for a licence name, then it returns only the individual licence pages described above, not the packages that use that licence. I checked the XML API and JSON API. They provide endpoints for listing all licences, and for listing all packages, but not for listing packages by licence. The entries returned by the "List of licenses" endpoints list only a unique ID, name, and free/non-free status for each licence, but not which packages use that licence. The entries returned by the "List of Packages" endpoints list only a unique ID, name, and brief description for that package, but not its licence. I could use the XML or JSON API to get a full list of packages, extract the unique IDs to construct the URL for each package's page on CTAN, download each of those pages, and then scrape the licence data. But there are currently almost 7000 packages, so scraping the site in this way will take a long time, and I'm not sure that the site operators would appreciate all that traffic. (My use case, in case anyone is wondering, is finding packages that are available on CTAN but that are not distributed with TeX Live due to licensing restrictions. I'm curious as to what sort of functionality I and other TeX Live users might be missing out on, and might decide to code freely licensed replacements for any seemingly useful non-free packages.)

A MWE is probably better than lengthy explanations: \documentclass[tikz,10pt]{standalone} \usetikzlibrary{positioning} % savedbox with a sketch \newsavebox{\sdbox} \sbox{\sdbox}{% \begin{tikzpicture}[scale=0.35] \node (rbox) [fill=red] at (1,0) {}; \node (bbox) [fill=blue] at (1,1) {}; \end{tikzpicture}% } \begin{document} \begin{tikzpicture}[scale=0.5,font=\small] % blocks \node (comp) {computer}; \node[right = 1cm of comp] (sb) {\usebox{\sdbox}}; % arrow \draw[->] (rbox) -- (comp); \end{tikzpicture} \end{document} Upon compilation, you'll notice that the arrow does not link the node (rbox) from its absolute position after the node (sb) is drawn, as it should go from the red rectangle to the computer box. Would it be possible to achieve that goal?

How do I directly input foreign scripts into LuaLaTeX equations? I'm using LuaLaTeX with the unicode-math package. I have text mode setup that uses fallback font for any glyphs not covered. I also want to do the same for math mode, but with different font choices. I'm currently unable to input a foreign script like Kanji and Thai without adding commands like \text{} around it, despite having fonts that support Kanji and Thai. I want to be able to input scripts like Kanji and Thai into equations without extra commands as long as I have the proper font for it. \documentclass{article} \usepackage{unicode-math} \directlua{ luaotfload.add_fallback ("textFallback", { "SimSun:mode=harf;", } ) } \setmainfont{Arial}[RawFeature={fallback=textFallback}] \setmathfont{Latin Modern Math} \begin{document} This is a sample text. この文章は日本語です。 $∀天∈ℝ, ∀ค∈ℝ, 天+ค∈ℝ$ \end{document} Edit: Added clarification and included the Thai script.

I'm a physics teacher and I'd like to share here my way to write "dynamical" exercises. After posting a couple of questions more or less related, I've read comments implying that my way of doing could be improved. When I say "dynamical" I mean that the variables of my problem (\mass, \speed, ...) are coded in the questions. I don't wanna hard-code for the following reasons: If I write everything with, say, m=3kg, and then I wanna change to m=2kg, I don't wanna rewrite everything. I can reuse the questions very fast with different values, e.g. for exams or for the students to practise. Below a MWE of a "typical" problem. Please, do not focus on the Physics, but on the LaTeX ideas, mainly: Could I improve the way I store variables and compute other quantities? For the units, which command should I use: mathrm; text ; textup; ... ? Anything else? I want to make clear that, even if in this example I use basic maths (mainly the 4 operations), I typically need all the usual fonctions (powers, log, sqrt, exp, trigo), so any solution that you suggest should handle all these functions. \documentclass{article} \usepackage{xfp} % provides \fpeval \usepackage{amsmath} \begin{document} \def\mass{3} \def\speed{10} \def\distance{1} \edef\Ekin{\fpeval{0.5*\mass*\speed^2}} \edef\force{\fpeval{0.5*\mass*\speed^2/\distance}} A mass $m=\mass\, \mathrm{kg}$ starts moving from rest.

I found a section formatting style on TeX Stack Exchange that I really like. The only issue is that it applies the same formatting to sections, subsections, and subsubsections, whereas I would like a clearer hierarchy with sections having boxed number + colored underline; subsections having colored number + underline; subsubsections having colored number and text (no underline). My current implementation is below. It mostly works, but for some reason, there is a gap in the underline between the section number box and the title. I am using titlesec and ulem for the underlining. \documentclass{article} % === Required packages === \RequirePackage[explicit]{titlesec} \RequirePackage{soul} \RequirePackage{xcolor} \definecolor{titlepagecolor}{rgb}{.13, .36, .38} % === Underline helper === \newbox\TitleUnderlineTestBox \newcommand*\TitleUnderline[1]{% \bgroup \setbox\TitleUnderlineTestBox\hbox{\colorbox{titlepagecolor}\strut}% \setul{\dimexpr\dp\TitleUnderlineTestBox-.3ex\relax}{.3ex}% {\color{titlepagecolor}\ul{\mbox{#1}}}% \egroup } % === (sub)Section numbers === \newcommand*\SectionNumberBox[1]{% \colorbox{titlepagecolor}{% \makebox[2.5em][c]{% \color{white}\strut\csname the#1\endcsname }% }% \hspace{0.5em}% } \newcommand*\SubsectionNumberColored{% {\color{titlepagecolor}\thesubsection}% } % === Section === \titleformat{\section} {\Large\bfseries\sffamily\color{titlepagecolor}} {\SectionNumberBox{section}} {0pt} {\TitleUnderline{#1}} % === Subsection === \titleformat{\subsection} {\large\bfseries\sffamily} {} {0pt} {% \TitleUnderline{% \SubsectionNumberColored\hspace{0.8em}#1% }% } % === Subsubsection === \titleformat{\subsubsection} {\normalsize\bfseries\sffamily} {} {0pt} {\textcolor{titlepagecolor}{\thesubsubsection\hspace{0.8em}#1}} \begin{document} \section{Section} \subsection{Subsection} \subsubsection{Subsubsection} \end{document}

There is no command rotated Khitan text format in LaTeX. \documentclass{article} \usepackage{xeCJK} \setCJKmainfont{NotoSerifKhitanSmallScript-Regular.ttf} \xeCJKDeclareCharClass{CJK}{"18B00 -> "18CD5} \begin{document} 𘬐𘬑𘬒 Doesn't type rotated Khitan text \end{document} References: How can xeCJK expand its support to include "new standard Unihan characters"?
