Why do I want to create a new mapping for unicode-math? I noticed that Unicode has sans-serif arrow keys in U+1F850 - U+1F859 range, but unicode-math and \symsf seem to only superficially include them. Also, I noticed that the NewCMMath font has additional sans-serif non-bold Greek characters, but it's not being recognized. Is it possible to create a new mapping in \symsf? \documentclass{article} \usepackage{unicode-math} \setmathfont{NewCMMath-Book.otf} \begin{document} Expected glyphs: $\symbol{"E002}\symbol{"E003}\symbol{"E007}\symbol{"E018}\symbol{"E019}\symbol{"E01A}\symbol{"1F850}\symbol{"1F851}\symbol{"1F852}\symbol{"1F853}\symbol{"E043}\symbol{"E044}\symbol{"E048}\symbol{"E059}\symbol{"E05A}\symbol{"E05B}$\\ Actual glyphs: $\symsf{\Gamma\Delta\Theta\alpha\beta\gamma\leftarrow\uparrow\rightarrow\downarrow}\symsfit{\Gamma\Delta\Theta\alpha\beta\gamma}$ \end{document}

I submitted a paper using the 'clean' IEEE conference template and got this confusing message. The paper is a little less than 6 pages. My references are less than 0.4 of the entire page on page 6 (i.e., just the right column with some space left at the bottom). EDAS accepted the paper after I fixed gutter = .24 problem. What is the message 'reference section starts on page 6.6' when I don't have anything beyond 6? I did not do anything fancy with the IEEE template, like squishing vertical spaces, etc. Literally took the template, inserted my content, compiled it, and uploaded it to EDAS. Any insight on EDAS behavior would be really appreciated. This is my 1st paper and first encounter with EDAS.

(For a LaTeX beginner, colleague of mine, since I don't have a Mac.) Is there a way to view in the Font Book the fonts included with a fresh installation of MacTeX?

I want to have my reference show (Skollag, 2010:800) when I do \parencite{...} and I want the reference to show in my \printbibliography as: Skollag (SFS 2010:800). Utbildningsdepartementet. https://www.riksdagen.se/sv/dokument-och-lagar/dokument/svensk-forfattningssamling/skollag-2010800_sfs-2010-800/#top I dont know what type of @type to make it and the ones I have tried dont fit the formating required.

I'm trying to build a logbook for my sailing vessel, I found some Templates, but they were so far from what I was looking for that I decided to start from scratch. The final result should be similar to this example: I started writing it and it took me some time to figure out how to make XeLaTeX create not only the document, but also the PDF in landscape format. After I figured that out I noticed that the Word "Test" (which I used as content) was a bit off the expected position, so I used showframe to get this visualisation of the main text area which is not really what I want (obviously). How do I make the Text area fit the page size? Code so far: \documentclass[12pt,landscape,a4paper]{article} \setlength{\pdfpagewidth}{\paperwidth} \setlength{\pdfpageheight}{\paperheight} \usepackage[]{showframe} \begin{document} Test \end{document}

I am a beginner at using LATEX. I have a question about increasing/decreasing the radius/curve/bulge of the voltage arrow. I am creating a very simple RLC series circuit along with a DC voltage source. I have attached my code below: \begin{circuitikz} \draw (0,0) to [american voltage source, invert, l=$V_s$] (0,6) to [R, l=$R_1$] ++(2.5,0) to [L, l_=$L$] ++(2.5,0) to [C, l=$C$, i=$i_C$, v^<=$v_C$] ++ (0,-6) to [short] ++(-5,0); \draw (2.5,6) to [R, l=$R_2$, *-*] ++(0,-6); \draw (0,0) node[ground, label=west:G] (GND) {}; \end{circuitikz} The output of this code is: As you can see, the text C and the arrow of v_c are sort of overlapping each other. I can easily overcome this issue by bringing the label C to the left or by bringing the voltage arrow to the left. However, I would like to know how I can manipulate the curvature of the arrow itself. I went through the CircuiTikZ User Manual, and questions such as this, this, this, and this but I was unable to solve the issue. I look forward to the opinion of the advanced LATEX users.

I am required to break the links within url{} to my references only after / or //, not after any other symbol that also might occur in a link. As can be seen in this post, this was achieved by adding \def\UrlBigBreaks{\do\/} to my code. Fixing this issue made another problem apparent though, as there would be no line break within certain links but right before them, leaving most of the line blank. How can this problem be resolved? By given guidelines, the list of references is to be formatted left-aligned without hyphenation, yet, links can include a line break after said symbols. Please see the following MWE and its output, especially Reference 1: \documentclass{article} \usepackage[hidelinks]{hyperref} \def\UrlBigBreaks{\do\/} \begin{document} {\raggedright \begin{thebibliography}{} \bibitem[Reference 1]{reference1} Available at \url{https://tex.stackexchange.com/one/two-three/four_five_six} \bibitem[Reference 2]{reference2} Available at \url{https://tex.stackexchange.com/seven-eight-nine/ten_eleven/twelve} \end{thebibliography} } \end{document} Context: This is a follow-up question to a question that I posted some time ago.

I want to recall a previous Corollary in a proof, but the corollary is included in \uncover<4-> and the link takes me back to the first version of the slide, where the corollary is not visible yet. I used hypertarget ad hyperlink instead of \cref (which is the one I knew) because I had some trouble with it. This is what Overleaf said, by the way: Package cleveref Warning: hyperref package loaded with implicit=false option - disabling cleveref's hyperref support.

I don't know what else to do, but I sense the items inside the cells are not vertically centered. I know some eyes might not notice that from far view, but I'm meticulous myself, apologise my ADHD. You can see, x is centered, but not with y which goes lower and those numbers which go too high up. This is the code that I go with: {\renewcommand{\arraystretch}{1} \begin{tabular}{|c|c|c|c|c|c|c|c|} \hline $x$ & $0$ & $1$ & $2$ & $3$ & $4$ & $5$ & $6$ \\ \hline $y$ & & & & & & & \\ \hline \end{tabular} } How to make it perfectly centered vertically?

The tip of arrow heads in TikZ usually extends on exactly the specified coordinate, for example in \draw[->] (0,0) -- (1,1);. Is it possible to align the center of the end mark automatically at the specified coordinate? This is useful for plotting piecewise defined functions using * or o as arrow heads such as in https://commons.wikimedia.org/wiki/File:Discontinuity_jump.eps.png. Another way to achieve a similar result is by calculating the coordinates of the points and adding the points manually by \filldraw[fill=white] (1,0.5) circle (0.75pt);. To illustrate what I would like to have: The center of the two circles should be in the middle of the two blue lines of the MWE. It would also be great if we could define certain x-values to set marks at exactly desired points.

I want to reduce the line spacing within an item or items. In example 2, \setstretch{1} has a side effect that the vertical space between the first item and its preceding text (2A) is also narrowed (compare with 1A without the command). Strangely, the space between the last item and its following text remains the same (1B and 2B). In other words, \setstretch{1} command affects the space between the first item and its preceding text. Shouldn't it be independent from the line spacing command? (enumitem package manual on page 3 says that the space before the first item depends on \topsep + \parskip [+ \partopsep] which is the same as the space after the last item.) How can I make the two spaces (1A and 2A) same while using \setstretch{1} command? Or, is there any other valid solution for this? (Of course, I know a not-a-beautiful one that I can manually add a space.)

I'm trying to stylize the mathematical fraction in such a way that both the numerator and the denominator will automatically shrink to roughly fit the line height and preferably the digits will be expanded horizontally to occupy more horizontal space. Being away from the TeX for the last 2-3 years I've consulted an AI-assistent first and it suggested using the afrc (Alternative Fractions) and the font Adobe Caslon Pro which it said supported the afrc but that didn't work out and I gave up asking the AI. "Almost" MWE \documentclass{article} \usepackage{fontspec} \defaultfontfeatures{Ligatures={TeX,Common}} \setmainfont{Adobe Caslon Pro}[] % it's installed on my system \begin{document} gimme {\addfontfeatures{RawFeature=+afrc}1/10} of your money % afrc -> Alternative Fractions \end{document}

I am asked to produce a document where a figure caption is placed above the figure, and left-aligned (even though it is just a one-line caption). By using the subcaption package and the \captionsetup command it works fine when the figure contains only one image. However, when the figure contains several sub-figures, the sub-captions are always left-aligned, like the main caption. I would like to have the main caption left-aligned but the sub-captions (which are very short) centred below each sub-figure. The following MWE illustrates the problem. Figure 1 is the standard. Figures 2 and 3 have the main caption left-aligned as required, but also the sub-captions come out left-aligned. \documentclass{article} \usepackage[document]{ragged2e} % For left-aligned (ragged right) text \usepackage{subcaption} \usepackage{graphicx} \usepackage{lipsum} \begin{document} \lipsum[66] \begin{figure}[h] \caption{Centered caption above figure} \label{fig:f01} \centering \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{1st}\label{subfig:1st}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{2nd}\label{subfig:2nd}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{3rd}\label{subfig:3rd}\end{subfigure} \end{figure} \lipsum[66] \begin{figure}[h] \captionsetup{singlelinecheck=off,justification=raggedright} \caption{Left-aligned caption above left-aligned figure} \label{fig:f02} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{1st}\label{subfig:1stb}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{2nd}\label{subfig:2ndb}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{3rd}\label{subfig:3rdb}\end{subfigure} \end{figure} \lipsum[66] \begin{figure}[h] \captionsetup{singlelinecheck=off,justification=raggedright} \caption{Left-aligned caption above centered figure} \label{fig:f03} \centering \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{1st}\label{subfig:1stc}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{2nd}\label{subfig:2ndc}\end{subfigure} \begin{subfigure}{0.30\textwidth}\includegraphics[width=\textwidth]{example-image-duck}\caption{3rd}\label{subfig:3rdc}\end{subfigure} \end{figure} \end{document} Thank you for your suggestions.

I am using VS Code with LaTeX Workshop and LTeX+ for spell checking. LTeX+ generates by default a ton of info messages like this: (Most of them false positives) I would like for it to stop generating these info messages. Here it is explained that a solution is to add "ltex.diagnosticSeverity": "hint" to the settings.json file. Nonetheless, as it is explained in the documentation, this makes any spotted spelling error not be underlined and rather only subtly marked. I would like for the errors in my code to still be underlined with a squiggly line (like with the default "ltex.diagnosticSeverity": "information" value). How could I achieve this?

What I want to replicate originally is something as below: Now my key point is the arrow of the following style, similar to the single arrow shape in shapes.arrows: \documentclass[tikz,border=5pt]{standalone} \usetikzlibrary{arrows.meta,positioning,shapes.arrows,decorations.markings} \begin{document} \begin{tikzpicture}[ node distance=2cm and 1cm, shrink/.style={shorten >=#1cm,shorten <=#1cm}, myarrow/.style={ shrink=.75,thick,-Stealth, postaction=decorate, decoration={ markings,mark=at position .5 with { \draw[shrink=0,-] (-10pt,-10pt) -- (10pt,10pt); } } }, mysinglearrow/.style={ shape=single arrow,minimum height=1.5cm,inner sep=3pt,draw,line width=1.2pt, } ] \node[draw] (betaII) {AAAAAAAA}; \node[draw] (betaI)[below left=of betaII]{BBBBBBBBB}; \node[draw] (normal)[below right=of betaII]{CCCCCCCCC}; \draw[myarrow] (betaII.west) -- (betaI.north); \draw[myarrow] (normal.north) -- (betaII.east); \draw[myarrow] (betaI) -- (normal); \node[mysinglearrow,rotate=45] at (-1.75,-1.5) {}; \end{tikzpicture} \end{document} However, that is not behave as a "arrow", but a shape. I dislike the syntax: \node[mysinglearrow,rotate=45] at (-1.75,-1.5) {}; Here below is the simplified version, based on the similar solution code here: % Source - https://tex.stackexchange.com/a/662285 \documentclass[tikz,margin=1cm]{standalone} \usetikzlibrary{arrows.meta} \tikzset{ doubleTriangle/.style args={#1 and #2 colored by #3 and #4}{ -Triangle, line width=#1,#3, postaction={ draw, -Triangle,#4, line width=#2, /utils/exec=\pgfmathsetlengthmacro{\doubleTriangleShortenStart}{((#1)-(#2))/2}, /utils/exec=\pgfmathsetlengthmacro{\doubleTriangleShortenEnd}{1.2*(sqrt(3))*((#1)-(#2))}, shorten <=\doubleTriangleShortenStart, shorten >=\doubleTriangleShortenEnd, }, }, } \begin{document} \begin{tikzpicture} \node[draw,below left] at (0,0) {A}; \node[draw,above right] at (5,5) {B}; \draw[doubleTriangle=1cm and 0.7cm colored by black and white] (0,0) -- (5,5); % \draw[doubleTriangle=1cm and 0.7cm colored by black and white,shorten >=.5cm,shorten <=.5cm] (0,0) -- (5,5); \end{tikzpicture} \end{document} which gives: Noted that the arrow's width is not the same. What I was after as an arrow style, is something as below: Any suggestions on how to make more elegant syntax of this arrow style?

When \wideoverbar is applied to a wide input, e.g., \wideoverbar{\alpha\alpha}, \wideoverbar{\alpha\alpha\alpha}, the bar is visually very snug up against the input, and this looks correct to me. However, when \wideoverbar is applied to a narrow input like \alpha, the depicted bar is raised significantly. I think \wideoverbar looks significantly better than \bar and \overbar in general, and would like to use it on narrow contents for reasons to do with both aesthetics and consistency. So, I am looking to get the behavior of wide inputs with narrow inputs. As some examples, \wideoverbar{\alpha} is spaced poorly, \wideoverbar{\alpha\alpha} is spaced well, \wideoverbar{\alpha.} is spaced well, but \wideoverbar{\alpha\!.} is spaced poorly. \wideoverbar{..} is spaced poorly, but \wideoverbar{...} is spaced well. Evidently, there is some "switch" on the vertical height of the bar which somehow depends on the width of the contents. I am using Lualatex with Unicode math + Libertinus math, in case that is relevant. For reference, here is a minimized compilable example of what I am working with: % !TEX program = lualatex \documentclass{acmart} \begin{document} $\wideoverbar{\iota}$, $\wideoverbar{\iota\iota}$, $\wideoverbar{\iota\iota\iota}$, $\wideoverbar{\iota\iota\iota\iota}$ \end{document} I find the vertical spacing on the right highly preferable. I had previously posted the question on reddit.

Consider the following example: \DocumentMetadata{% tagging = draft % } \documentclass{article} \begin{document} a \newpage \begin{enumerate} \item b \end{enumerate} c \end{document} If I compile this document using latexmk with no .aux file, I get the following error: ! Package tagpdf Error: there is no open structure on the stack Type <return> to continue. ... l.16 ? Notes: Line 16 appears to be the blank line between \end{enumerate} and c. With tagging = on or tagging = off it compiles fine, but tagging = draft yields an error. Using lualatex <filename> directly instead of latexkmk -lualatex <filename> it compiles fine. If there is an .aux file left over from a previous run (like if I run once using tagging=on and then switch to tagging=draft, or if I run once using lualatex and then switch to latexmk -lualatex) it compiles fine. (Using Tex Live, updated as of May 28, 2026, in Windows 11 Enterprise.) Questions: Is this expected behavior? If not, should a report be filed? If so, where? (To latexmk, or the tagging project, or both, or somewhere else?) Work-arounds in case anyone else ever encounters this issue: Evidently there are many ways to avoid it (see items 2, 3, 4 above).

I have a collection of exercise files that I later assemble into worksheets/tests. A simplified example looks like this: \begin{subexercises} \subexercise Hello \subexercise World \subexercise ! \subexercise ? \end{subexercises} \subexercise is a custom wrapper around \item that also handles additional formatting (margin notes, points, etc.). I would now like to selectively include only certain subexercises without editing the source files each time. For example, with something like \renewcommand{\subexselect}{1,4} I would want the output to contain only a) Hello b) ? So the numbering should remain continuous even though some subexercises are skipped. I also would like to keep the \item-like syntax \subexercise Hello instead of changing all files to something argument-based like \subexercise{Hello} because I already have many existing exercise files and like the syntax better (and partly also because I'm interested in how to achieve this and maybe learning something new that way). What I tried 1. Using conditionals inside \subexercise I experimented with \if...\fi constructs and tried to place balancing \iftrue / \fi pairs into begin/end hooks of the environment. I could not get this to work reliably. 2. Using pgfparser to gobble unwanted items I then tried parsing tokens until the next \subexercise and discarding them when the current item should not be printed. This almost works, except for the final item because there is no following \subexercise token to stop the parser. I also tried using \end{subexercises} as an alternative stop condition, but I could not figure out how to do this properly since it is not a single token. It works with an additional stop-marker at the end of the environment but having to manually insert this marker at the end of the environment is bad. Here is a minimal example of that attempt (when not including 4 in the list I get an emergency stop): \documentclass{article} \usepackage{enumitem} \usepackage{pgfparser} \newlist{subexercises}{enumerate}{1} \setlist[subexercises]{label=\alph*)} \newcommand{\subexselect}{} \newcounter{subexcount} \setcounter{subexcount}{0} \newcommand{\subexercise}[1][]{% \stepcounter{subexcount}% \ifnum\pdfmatch{\thesubexcount}{\subexselect}=1% \item \else \pgfparserparse{subex}% \fi } \pgfparserdef{subex}{all}\subexercise{\pgfparserswitch{final}\pgfparserreinsert} \pgfparserset{subex/silent=true} %\newcommand{subexend}{} %\pgfparserdef{subex}{all}subexend{\pgfparserswitch{final}} %\pgfparserdeffinal{subex}{} \begin{document} \renewcommand{\subexselect}{1,4} \begin{subexercises} \subexercise Hello \subexercise World \subexercise ! \subexercise ? %subexend \end{subexercises} \end{document} Question How can this kind of selective inclusion be implemented while preserving the \item-like syntax, i.e. not replacing subexercise by a macro that takes the body of the \item as argument?
