Deformed and undeformed configurations of the beam Hello everyone, I am trying to reproduce this image using LaTeX TikZ. I have written the code below, but I am encountering difficulties when drawing the curved line through the thickness (the yellow line).

When I generate diagrams with matplotlib/seaborn, I find it difficult to set up the padding and what not for it fit properly and have proper consistency across diagrams. Does anyone use this stack and get things running porperly? What I am doing now is gnerating csvs and directly doing tikz but I would like to avoid that.

I upgraded from TeXLIVE 2023 to TeXLIVE 2026 recently (along with Fedora 43 to 44), and I could have sworn that the following used to work: \documentclass{article} \usepackage{fontspec} \setmainfont[Ligatures=TeX]{XCharter} \begin{document}\noindent Għajnsielem\\ OR\\ G\hwithstroke ajnsielem \end{document} Now, when I run this with lualatex, I get six errors like this: Missing character: There is no ħ (U+0127) in font [XCharter-Roman.otf]:mode=node;script=latn;language=dflt;+tlig;! and the missing character is a box. (n.b., Għajnsielem is a municipality in Malta, but I picked it primarily because I knew it had that character in it.) I suspect I have a font file missing or something that didn't survive the upgrade, but I wanted to make sure it is something with my operating system's packaging of XCharter or other font packages before I chase this down a rabbit hole. I thought I at least got a character there, not a box, in the past, and I don't remember there being a warning message or error, either, from the old version.

I would like to create in my Europass document \documentclass[italian,a4paper]{europasscv} \usepackage[italian]{babel} \usepackage[most]{tcolorbox} \DeclareRobustCommand\ebseries{\fontseries{eb}\selectfont} \DeclareTextFontCommand{\texteb}{\ebseries} \definecolor{marine}{HTML}{214493} \ecvname{Cristiano Euro} \newtcolorbox{mybox}{ enhanced, boxrule=0pt,frame hidden, borderline west={3pt}{-10pt}{marine}, colback=white, sharp corners } \begin{document} \begin{europasscv} \sffamily \ecvpersonalinfo{} \ecvbigitem{Posizione ricoperta}{ingegnere} \ecvsection{ingegnere} \ecvtitle{2011 – in corso}{C-Med} \ecvitem{}{\begin{mybox} Buyer con 4 anni di esperienza nel settore strategico degli acquisti, focalizzata sull’ottimizzazione delle condizioni di acquisto di C-Med.

The following MWE produces an error with TeXLive 2025: % !TeX program = lualatex \documentclass{article} \usepackage{microtype} \usepackage{titletoc} \begin{document} \end{document} Error: !

Workaround (works but disables only the toc protrusion patch): \usepackage[nopatch=toc]{microtype} Is there a more targeted fix, or is this a known bug?

Could I have, in a .bbx file for BibLaTeX, a : \DeclareNameFormat{author} clause for author names in small capitals ? \textsc{\MakeUppercase{\namepartfamily}} doesn't.

When using the book documentclass, the \tableofcontents tries to avoid leaving a chapter title alone at the end of a page. When loading the bigfoot package, this behaviour is removed. In the following code, the title of chapter 6 is left alone at the end of the first page. Commenting out the line \usepackage{bigfoot} moves the chapter title to the next page. Is there a way to retain the default behaviour while also loading the bigfoot package? \documentclass[oneside]{book} \usepackage{bigfoot} \begin{document} \tableofcontents \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} %\subsection{Subsection title} \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \chapter{Chapter title} \section{Section title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \subsection{Subsection title} \end{document}

I am using the natbib citation management package with the aug08 bibliography style. When I use \cite{something} or \citealp{something} in line with the content, the letters of the citation call-out are in italics. How do I keep them from being italic globally? below is the minimal working example \documentclass[12pt]{report} \usepackage[letterpaper,left=1in,right=1in,bottom=1in,top=1in]{geometry} \usepackage[T1]{fontenc} \usepackage[authoryear]{natbib} \begin{document} \cite{bretherton2005} (\citealp{bretherton2005}). \bibliography{thesis} \bibliographystyle{agu08} \end{document}

I'm playing with a book cover (a novel) with the title separated on three lines. The first part is left aligned to the page, the middle part is centered, and the last part is (should be) right aligned. Currently, my title page is almost right, but I'm experiencing an horizontal glitch that I don't understand. Here's the MWE code that shows the issue. What is wrong with it? \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt]{geometry} % Option showframe pour montrer les bordures. \raggedbottom \hyphenpenalty=2000 \exhyphenpenalty=2000 \usepackage{titlesec} \usepackage{graphicx} \usepackage[dvipsnames]{xcolor} \usepackage{float} \usepackage[titles]{tocloft} \usepackage[dvipsnames]{xcolor} \usepackage{transparent} \usepackage{tikz} \usetikzlibrary{calc} \titleformat{\chapter}[display] {\normalfont\huge\bfseries\centering} {\chaptertitlename\ \thechapter}{20pt}{\Huge} \begin{document} \frontmatter \begin{titlepage} \definecolor{lightbrown}{RGB}{177, 149, 93} \definecolor{darkred1}{RGB}{60, 25, 0} \pagecolor{darkred1} \begin{tikzpicture}[remember picture, overlay] \draw[line width = 1in,color = white] ($(current page.north west) + (0.25in,0.25in)$) rectangle ($(current page.south east) + (0.25in,-0.25in)$); \draw[line width = 0.25pt,color = black] ($(current page.north west) + (0.75in,-0.25in)$) rectangle ($(current page.south east) + (-0.25in,0.25in)$); \draw[line width = 1pt,color = white] ($(current page.north west) + (1in,-0.5in)$) rectangle ($(current page.south east) + (-0.5in,0.5in)$); \end{tikzpicture} \centering {\textcolor{lightbrown}{\Huge\sffamily Author's name}} \vfill \raggedright {\textcolor{lightbrown}{\fontsize{58}{0}\selectfont\sffamily\textbf{{WOORLDS}}}} \\[2.5\baselineskip] \centering {\textcolor{lightbrown}{\fontsize{48}{0}\selectfont\sffamily\textbf{{of}}}} \\[2.5\baselineskip] \raggedleft {\textcolor{lightbrown}{\fontsize{58}{0}\selectfont\sffamily\textbf{{WOORMS}}}} \\[2\baselineskip] \vfill \centering \vfill \vfill \vfill {\textcolor{brown}{\Large\selectfont\sffamily Copyright Notice}} \end{titlepage} \pagecolor{white} \end{document} Also, the middle part should be well centered, horizontally AND vertically between the first and last part of the title. I'm not sure the code is properly done. Any advice on this would be greatly appreciated. Here's a preview of what this code is doing (don't mind about the weird title. This is just for the the MWE): As you could see on the picture, the last part of the title ("WOORMS") have more space to its right that the left of the fist part ("WOORLDS"). Also, I'm not sure that the middle part ("of") is well centered, vertically and horizontally.

What I want to achieve is something like: Noted that the "glow" here is somewhat like a "shadow" path out of the border. However, I have tried blur shadow={shadow xshift=0pt,shadow yshift=0pt,shadow scale=1.05}: \documentclass[tikz,border=5pt]{standalone} \usetikzlibrary{shadows.blur,spy} \begin{document} \begin{tikzpicture}[spy using outlines={circle, magnification=3, size=3cm}] \draw[fill=gray!25,draw,rounded corners,blur shadow={shadow xshift=0pt,shadow yshift=0pt,shadow scale=1.05}] (40:4) arc[start angle=40,end angle=140,radius=4] -- (140:2) arc[start angle=140,end angle=40,radius=2] -- cycle; \draw[fill=white] (0,2.75) -- ++(.5,-.25) -- (0,3.5) -- ++(-.5,-1) -- cycle; \spy[red] on (140:2) in node at (-2,-1); \spy[blue] on (40:2) in node at (+2,-1); \end{tikzpicture} \end{document} The shadow glow is not what I was after: Is that possible to provide the shadows for such ideal glow for irregular shape?

I use \note{} frequently when preparing Beamer presentations, but a note often becomes too long to fit on a single page, leading Beamer to truncate the remaining text. Is there a way to allow a note to span multiple pages automatically? Ideally such a feature would work similarly to the allowframebreaks option for frames. A minimal working example: \documentclass{beamer} \usepackage{lipsum} \setbeameroption{show notes} \begin{document} \begin{frame}{Example Frame} This is a sample frame. \end{frame} \note{ \lipsum[1-6] % intentionally long note } % Desired (but not supported): % \note[allowframebreaks]{ % \lipsum[1-6] % } \end{document}

I have the following code: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture} \draw[fill=gray!25,draw,rounded corners=8pt] (40:2) -- (40:4) arc[start angle=40,end angle=140,radius=4] (140:4) -- (140:2) arc[start angle=140,end angle=40,radius=2] (40:2) -- cycle; \end{tikzpicture} \end{document} which I think would get a rounded sector, but in fact: Any paraphase on this? Maybe related ?

Using BibDesk with Biblatex on a huge .bib file, every entry has a "date-added" field. Is it possible to use this one as the source of the "urldate" field for "online" entries?

I want to write a command that takes 2 optional arguments (using xargs package) and depending on whether they are empty or not, print 3 different things, like so: \newcommandx{\foo}[2][1,2]{ \ifthenelse{\equal{#1}{}} {\fooA} { \ifthenelse{\equal{#2}{}} {\fooB{#1}} {\fooC{#1}{#2}} } } But when using either \foo[a] or \foo[a][b], I get the error Argument of \xargs@grab@opt has an extra }. I know it has something to do with \ifthenelse not being expandable, but I don't understand latex at that level. Is there some 'easy' way to solve this?

When polyglossia is loaded it seems that \AtBeginDocument fails to do its work. The following code \documentclass[12pt]{article} \usepackage{fontsetup} \usepackage{polyglossia} \setmainlanguage{english} \setotherlanguage{greek} \AtBeginDocument{\addfontfeatures{StylisticSet=6,StylisticSet=7}} \begin{document} θυμήθηκα \addfontfeatures{StylisticSet=6,StylisticSet=7} θυμήθηκα \end{document} produces So the \AtBeginDocument did not work (the thetas must be different as in the second line). Now if you comment out the lines of polyglossia, things work as expected, that is both lines produce the same output as in the second line of the picture above. What is wrong with the above code or with polyglossia?

I defined a command: \newcommand{\hexacc}[2]{% \BeginAccSupp{method=hex,unicode,ActualText=#2}% #1% \EndAccSupp{}% } How to make it so that when I put \hexacc{A}{1000}\hexacc{V}{2137} (this is just an example), it respects the original kerning while still having a distinct A and V part I can copy separately so that I can later reuse my custom \hexacc{A}{1000} as, say, \customA and the same for other letters, and have \customA\customV respect the original kerning of AV? The A and V example was just an example, I want it to work for any letter

I want to create a multi part parallelogram input block for a flowchart. There is no multi part trapezium shape that exist so for now I used a standard rectangular multi part shape with the xslant option to make it look like a parallelogram. I defined a style that I can easily reuse. The problem is that the text is also slanted, and if possible I would like it normal. Is there a way to apply xslant only to the shape and not to the text ? I tried creating a second node only for the text but the problem is that the paralellogram doesn't resize properly to fit the text. My MWE : \documentclass[class=article]{standalone} \usepackage[]{xcolor} \usepackage{tikz} \usetikzlibrary{shapes} \tikzstyle{io} = [rectangle split, rectangle split parts=2, xslant=0.4, draw, rectangle split part fill={blue!50,blue!20}, text centered, minimum width=4.25cm, minimum height=2cm] \begin{document} \begin{tikzpicture} \draw (0,0) node[io,name = ,align = center]{Parameters\nodepart{two} $\alpha$, $\eta$}; \end{tikzpicture} \end{document} Thanks for your help.

Is there a way to continue a path we draw using \draw with a plot, just as we do for instance also with arc or similar commands? In the example below I have a straight line, but I'd like the plot to append directly to that line, as indicated by the red dots. I can of course do that e.g. with plot[shift={(1,1)},...], but that means that I have to repeat that second coordinate in the path, which makes it again more cumbersome to use if we want to change something later (and the second straight line segment then points to the original endpoint without the shift). So this is more a question about "ergonomically" using this plot command inside other paths. E.g., I also like using the ++ syntax to precisely extend a path a certain distance horizontally, without having to repeat the previous y-coordinate, and I was wondering whether there is something similar we can do with the plot command inside such a path. \documentclass{standalone} \usepackage{tikz} \usepackage{xcolor} \usepackage{pgfplots} \pgfplotsset{compat=1.17} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[domain=0:4] \draw[black!10!white, dashed] (0, 0) grid (4, 2); \draw (0, 1) -- (1, 1) node[left] {} plot[domain=0:1, samples=100] function{sin(6.3*x)} node[right] {} -- ++(1, 0); \end{tikzpicture} \end{document}

My question is essentially the same as this question, but I'm asking again because the answer provided is not very resilient. In particular, it doesn't work for the kind of diagram I want. I want to use Tikz to draw a diagram with lots of nodes and arrows; essentially, a flowchart. The diagram should start with a single node which is centered on the page (in the MWE below, this is the "Hello there" box). If I try to just use the \centering command, the whole picture gets centered, which is not what I want. The answer I linked above suggests using the \useasboundingbox command. However, this doesn't seem to do what I want. Here is my minimal working example: \documentclass[a4paper, 11pt]{article} \usepackage{tikz} \begin{document} This is a line of text which has been written with no purpose other than to help illustrate how the figure below appears on a page. \begin{figure}[ht] \centering \begin{tikzpicture}[rect/.style={rectangle, draw=black, thin}] \node[rect] (box1) at (0,0) {Hello there}; % Location 1 \node[rect] (box2) at (5,-1) {Hi}; % Location 2 \end{tikzpicture} \end{figure} This is a line of text which has been written with no purpose other than to help illustrate how the figure above appears on a page. \end{document} The linked answer suggests using the command \useasboundingbox (box1.south east) rectangle (box1.north west);. If I put this command at location 2, then the bounding box includes both boxes "Hello there" and "Hi", and the box "Hello there" is not centered (see below). If I put this command at location 1, then the bounding box only includes the "Hello there" box; this centers it the way I want, but then the box "Hi" ends up overlapping with the text below (see below). How can I make the "Hello there" box be centered on the page?

I want to implement given formatting requirements, however, I feel overwhelmed by the number of parameters and their dependencies, and, thus, I don't know which to begin with, as I feel like all of them need to be considered simultaniously. Furthermore, there are even more formatting requirements to fulfill, yet, the following should be the most essential ones, which is why I want to implement these first and condensed them in a table: I use the KOMA-script class scrreprt and would have used the parskip=full- option to seperate paragraphs from each other. If there is any info missing, please tell me and I'll provide it. And if some requirement seems odd, please also let me know. Thanks in advance!

The MWE's output looks like this (1st page cropped): At this point, the two only remaining areas where I need help are: Does the code that should eliminate the added vertical spacing around the section headings which parskip effects look correct and effective? Is there a way to check the respective sizes of beforeskip and afterskip? In theory, they should be correct as they were set manually, yet, when I compare the font size of chapter and the line spacing of section (they should be the same) measured with a ruler on a monitor (I know ... but it aint stupid if it works) they are not the same, or am I misunderstanding their theoritical (not code) definition here? If these (bonus) questions justify a new post, please let me know. Just thought they benefit from the overall context of the original question and are still somewhat linked to it. Thanks once again!

I have created a custom ⍟ symbol using TikZ, which works well, except that it ignores the colour of the surrounding text. MWE: \documentclass{article} \usepackage{tikz} \usepackage{scalerel} \newsavebox{\whitecircstar}\sbox{\whitecircstar}{\kern.075em\tikz{\node[draw, circle,line width=.36pt, inner sep=0]{$*$};}\kern.075em} \newcommand{\ostar}{\mathbin{\scalerel*{\usebox{\whitecircstar}}{\odot}}} \begin{document} \textcolor{red}{Before $\ostar$ After} \end{document} Output: How can I make \ostar the same colour as the surrounding text? My understanding was that . was a special symbol for the current colour in xcolor, but adding color=. to the node arguments had no effect.

My goal is to get a rectangle like the one below, but with text in the nested rectangles. Line types could be for example the following: I saw tikz: Multiple splits of rectangle, but it does not answer the question on the line types. Beyond that, I am a beginner using Tikz, and I'd like the answer explained, since the linked answer is complex to understand. Thanks!
