I am using \usepackage[xindy]{imakeidx} \makeindex[options=-L russian -C utf8] \makeindex[name=persons2, title=Именной указатель, columns=3 , options=-L russian -C utf8] to generate both subject and name indexes. Commands like \index{частота!круговая} \index[persons2]{Альфвен} write the terms into the PlasmaBook5.idx and persons2.idx files respectively. Next, the commands \printindex \printindex[persons2] located near the end of the book сall the makeindex.exe program directly from the xelatex or lualatex compiler. makeindex.exe generates .ind files on the fly, and the \printindex commands insert them into the text of the PlasmaBook5. Very convenient! Just two months ago, in mid-October, this scheme worked perfectly, but now suddenly the makeindex.exe program stopped generating .ind files with the following error: (D:/Users/KIA/YandexDisk/PlasmaBook5/Common/index2.tex*** - Win32 error 267 (ERROR_DIRECTORY): The directory name is invalid. It's clear that makeindex.exe doesn't find the directory where the .idx file is located, but I don't understand what needs to be changed to fix this problem. I use MikTeX in conjunction with WinEdt. WinEdt is configured to write .idx files to the TeXAux subdirectory. I don't recall changing WinEdt's settings recently. Perhaps a Windows 11 update broke this setup.

I am writing a thesis with upright sans maths and use a lot of fonts and symbols. For this I've declared letters and numbers as symbols, and it works reasonably well. Except that Libertinus has gotten rid of the commands to switch to lining numbers and tabular lining numbers locally: \liningnumsf{...\, \tabularnumsf{\liningfigures{...}} etc. Consider the three points in the following image where I switch to text mode inside maths: numbers are oldstyle, and I wish to make them line up. I think I need a local fix, as it was possible with Libertine, see above. The code: \documentclass{book} % This file shows a configuration for upright sans maths fonts with Libertinus and Libertinus Math \usepackage[LGR,T1]{fontenc}

I want to install the elstob_font to my texmf-local directory. In the TeX folder and elstob-package.pdf in the project, we know that: This package supports Elstob, the variable font for medievalists (and others). The package requires LuaLATEX, since LuaTEX is the only flavor of TEX that supports variable fonts. Elstob is not in CTAN, so you must install the font in your system in order to use it (be sure to get “Elstob,” the variable version, not “ElstobD,” the static font). Place the files elstob.styand elstob.luain the same directory with the document you’re working on. But I want to install this package to my machine.

I use biblatex to lay out my academic CV. I want to have a custom type for grants/funding I have secured and a custom type for research visits I have been on. I have achieved this -- these are Funding and Visit below. Since the visits are often funding by the grants, I then want to use the biblatex 'related' mechanism to associate one with the other, and print this information in the bibliography. In particular, I want to set the related field in funding entries to the key of a related Visit entry, set the relatedtype field to fundingfor, and then have the information printed in the bibliography. I have achieved all this, except that the related information is only printed for the first Funding entry to be printed. Here's an MWE: \documentclass{article} % Declare new types \begin{filecontents}[overwrite]{\jobname.dbx} % Visit \DeclareDatamodelEntrytypes{visit} \DeclareDatamodelEntryfields[visit]{ date,day,endday,endmonth,endyear,month,year, institution, } % Funding \DeclareDatamodelEntrytypes{funding} \DeclareDatamodelEntryfields[funding]{ date,day,endday,endmonth,endyear,month,year, title } \end{filecontents} % Declare bib formatting \begin{filecontents}[overwrite]{\jobname.bbx} \RequireBibliographyStyle{standard} \NewBibliographyString{fundingfor} \DefineBibliographyStrings{english}{% fundingfor = {funding for} } \newbibmacro{visitto}{% \printtext{visit to\addspace}% \printlist{institution}% } \newbibmacro{related:fundingfor}[1]{% \entrydata{#1}{% \usebibmacro{visitto}% }% } \DeclareBibliographyDriver{visit}{% \usebibmacro{bibindex}% \usebibmacro{begentry}% \usebibmacro{visitto}% \usebibmacro{finentry}% } \DeclareBibliographyDriver{funding}{% \usebibmacro{bibindex}% \usebibmacro{begentry}% \printfield{title}% \newblock{\addspace}% \usebibmacro{related}% \usebibmacro{finentry}% } \end{filecontents} % Examples of new types \begin{filecontents}[overwrite]{\jobname.bib} @Funding{fund_foo, title = {ZBig grant}, relatedtype = {fundingfor}, related = {visit_baz} } @Funding{fund_bar, title = {Large award}, relatedtype = {fundingfor}, related = {visit_qux} } @Funding{fund_boo, title = {Sizeable sum}, relatedtype = {fundingfor}, related = {visit_far} } @Visit{visit_baz, institution = {Impressive place} } @Visit{visit_qux, institution = {Prestigious location} } @Visit{visit_far, institution = {Somewhere else} } \end{filecontents} \usepackage[ bibstyle=\jobname, datamodel=\jobname ]{biblatex} \addbibresource{\jobname.bib} \begin{document} \nocite{*} \printbibliography \end{document} Which produces: The entries are structurally identical and obviously the driver is the same for each, so I would expect that if one prints the related data they all should. If I edit the data so that a different Funding entry sorts first (e.g change 'Big Grant' to 'ZBig Grant') it's still whichever is first to print that gets the related information, and none of the others. Why is the happening, and how can I fix it? TIA!

The following is a minimal example to demonstrate a problem I'm having with changing my margins in a book so that one two-page spread has a certain amount of whitespace in the margins, and the next two-page spread has different margins. \documentclass[12pt]{book} \RequirePackage[paperheight=9.0in,paperwidth=6.0in,bindingoffset=0.3in,inner=0.5in,outer=0.5in,bottom=0.5in]{geometry} \usepackage{lipsum} \newenvironment{widermargins}% {\expandafter\newgeometry{outer=1.2in,bottom=1.2in}}% {\restoregeometry} \begin{document} \thispagestyle{empty}\null\newpage % \begin{widermargins} \lipsum[1-4] \end{widermargins} \vfill\pagebreak % \lipsum[5-11] \end{document} Compiled with pdflatex, this generates a five-page document with a two-page spread on pp. 2-3 and another spread on pp. 4-5. The first spread is supposed to have bigger margins than the second spread. What I observe is that on pp. 4-5, the lengths of the pages are unbalanced. The left-hand page still seems to have the bigger bottom margin left over from the first two-page spread. The smaller bottom margin does finally kick in on the right-hand page, so the text column on the right is longer than the one on the left. If anyone can help me to fix this, I would appreciate it very much.

Disclaimer This question is a bit of "do it for me" but there is a histrory behind it, see this question. User Jasper offered me a solution without using pgfplots. I plan to add a bounty as soon as it is possible. Question I want to create diagram with a 3D line plots. The main feature is to have several x axes that share the same y axis. Each x axis has its own F (or z) axis. There are only data points on specific y values (in the example below at +30, +15, 0, -15). In addition, the y axis is reversed (+ and - direction reversed). I need a grid in each F-x plane. Important ist also, that all F axes share the same min and max. Each axis should have a label and the diagram should have a title. The data is given in separate csv files, see example below. The MWE contains the data and plots the data (for testing) using pgfplots. Goal: The goal is to have a plain tikz solution and maybe in addition, a solution based on luadraw or lua-tikz3dtools respectively. I am looking for a easy-to-use custom interface for my plot task. If the result looks as it is created with pgfplots, then I am happy. S!#i, I forgot a key feature (not shown in the hand drawing) In addition to the x-F plots described above, there is ONE plot in the y-F plane (= from left to right). This works, because all F axes share the same min and max. \begin{filecontents*}{y_F_data.csv} y,F -15,20 -14,8 30,-4 \end{filecontents*} \documentclass{article} \usepackage{pgfplots} % ------------------------------- \begin{filecontents*}{x_zero.csv} x,F -30,12 -29,8 30,-4 \end{filecontents*} \begin{filecontents*}{x_neg_one.csv} x,F -30,12 -29,8 30,-4 \end{filecontents*} \begin{filecontents*}{x_pos_one.csv} x,F -30,12 -29,8 30,-4 \end{filecontents*} \begin{filecontents*}{x_pos_two.csv} x,F -30,12 -29,8 30,-4 \end{filecontents*} % ------------------------------- \begin{document} \begin{tikzpicture} \begin{axis}[ axis lines = center, title = {$x_0$}, xlabel = {$x_0$}, ylabel = {$F_0$}, xmin = -30, xmax = 30, ymin = -100, ymax = 100, ] \addplot table [x=x, y=F, col sep = comma] {x_zero.csv}; \end{axis} \end{tikzpicture} \begin{tikzpicture} \begin{axis}[ axis lines = center, title = {$x_{-1}$}, xlabel = {$x_{-1}$}, ylabel = {$F_{-1}$}, xmin = -30, xmax = 30, ymin = -100, ymax = 100, ] \addplot table [x=x, y=F, col sep = comma] {x_neg_one.csv}; \end{axis} \end{tikzpicture} \begin{tikzpicture} \begin{axis}[ axis lines = center, title = {$x_{1}$}, xlabel = {$x_{1}$}, ylabel = {$F_{1}$}, xmin = -30, xmax = 30, ymin = -100, ymax = 100, ] \addplot table [x=x, y=F, col sep = comma] {x_pos_one.csv}; \end{axis} \end{tikzpicture} \begin{tikzpicture} \begin{axis}[ axis lines = center, title = {$x_{2}$}, xlabel = {$x_{2}$}, ylabel = {$F_{2}$}, xmin = -30, xmax = 30, ymin = -100, ymax = 100, ] \addplot table [x=x, y=F, col sep = comma] {x_pos_two.csv}; \end{axis} \end{tikzpicture} \end{document}

I’m defining datas in LaTeX with a custom command that stores both a label and a number: \documentclass{article} \usepackage{parskip} \newcommand{\data}[3]{% \expandafter\newcommand\csname #1\endcsname[1][]{#2##1}% \expandafter\newcommand\csname #1Number\endcsname{#3}% } \newcommand{\getnumber}[1]{% \mbox{\textbf{(\csname #1Number\endcsname)}}% } \begin{document} \data{tempA}{aaa}{1} \data{tempB}{bbb}{2} \data{tempC}{ccc}{3} \data{tempD}{ddd}{4} \data{tempE}{eee}{5} \data{tempF}{fff}{6} Data: \tempA \newline Number: \getnumber{tempA} \end{document} For a single compound, \getnumber{tempA} outputs (1). Now I want to create a command that takes a list of compound names and outputs a range summary of their numbers. For example: \getnumberrange{tempA,tempB,tempC,tempF} % should produce (1-3,6) I’m not sure how to iterate over a list of command names, retrieve their numbers, and compress consecutive numbers into ranges. How can I implement this in LaTeX?

I'm writing a thesis with loads of maths. The body text is set in Libertine (that is, with serifs), and all maths is set in Biolinum (meaning sans serifs) and upright. To make writing and reading the source code easier, and to have proper maths kerning in particular, I would like to set Biolinum in upright shape as the default maths font. I use libertinust1math already. The MWE explains it: \documentclass{article} \usepackage[LGR,T1]{fontenc} \usepackage[oldstyle,proportional,ttscale=0.875]{libertine} \renewcommand*\ttdefault{lmtt} \usepackage{libertinust1math} \usepackage[libertinus,biolinum,greek=up,scale=1]{libgreek} \usepackage[normalweight=autolight,boldweight=autosemibold,onlysansmath]{mdsymbol} \usepackage{mathtools} \begin{document} \mathversion{sans} \begin{enumerate} \item \verb|$ChS_{(M)}^2$| should look like $\textsf{ChS}_{(\textsf{M})}^\liningnumsf{2}$. \item \verb|$\mathit{ChS}_{(\mathit{M})}^2$| should look like $\textit{\sffamily ChS}_{(\textit{\sffamily M})}^\liningnumsf{2}$, just with the proper maths kerning, of course. \item \verb|$\mathnormal{ChS}_{(\mathnormal{M})}^2$| as well as \verb|$\mathsf{ChS}_{(\mathsf{M})}^2$| should look like $\textsf{ChS}_{(\textsf{M})}^\liningnumsf{2}$ again (same as first line). \item \verb|$\mathbf{ChS}_{(\mathbf{M})}^2$| should look like $\textbf{\sffamily ChS}_{(\textbf{\sffamily M})}^\liningnumsf{2}$. \item \verb|$\mathbf{\rmfamily ChS}_{(\mathbf{\rmfamily M})}^\mathrm{2}$| should look like $\textbf{\rmfamily ChS}_{(\textbf{\rmfamily M})}^\liningnums{2}$. \item \verb|$\mathrm{ChS}_{(\mathrm{M})}^\mathrm{2}$| should look like $\textrm{ChS}_{(\textrm{M})}^\liningnums{2}$. \end{enumerate} Numbers 1--4 are Biolinum (meaning \textit{sans serifs}). Numbers 5--6 are Libertine (meaning \textit{with serifs}). \end{document} I suspect this can perhaps be done using the \SetMathAlphabet command, like in \SetMathAlphabet{\mathrm}{normal}{\encodingdefault}{cmss}{\sfdefault}{n} \SetMathAlphabet{\mathbf}{bold}{\encodingdefault}{cmss}{\bfdefault}{n} but I don't know how to do it exactly. Important: I use pdflatex and cannot switch. PS >> The solution is modifying \usepackage{libertinust1math} to \usepackage[sansmath]{libertinust1math} in egreg's answer below. Then also the numbers are sans. Throughout. But one can switch the numbers back to serifs for the \mathrm style with the Tex command \rm. Alright for me as I (almost) don't use serifs in maths mode. UPDATE >> The sansmath option isn't actually a solution because it destroys the \upvarphi that I need. Furthermore: I have two pieces of news, one good, one bad. They both concern egreg's answer (now updated) in its previous state. First the good one. The code \DeclareSymbolFont{letters}{T1}{LibertinusSans-TLF}{m}{n} \DeclareMathAlphabet{\mathit}{T1}{LibertinusSans-TLF}{m}{it} \DeclareMathAlphabet{\mathsf}{T1}{LibertinusSans-TLF}{m}{n} \DeclareMathAlphabet{\mathbf}{T1}{LibertinusSans-TLF}{b}{n} \DeclareMathAlphabet{\mathrm}{T1}{LibertinusSerif-TLF}{m}{n} does work nicely and produces the required outcome, so that one has upright sans maths and can switch between variants as well. However, the sans numbers come from a different font. They look rather good, austere, much better in any case than AMS sans numbers. But they're still not Libertinus Sans. I've found the solution at Changing Number Font Into Sans Serif (by egreg), and applied it. Numbers in maths mode are then from Libertinus Sans. However, and this is the bad news, many symbols don't work anymore with the above code added. MWE, updating the MWE from above: \documentclass{article} \usepackage[LGR,T1]{fontenc} \usepackage[oldstyle,proportional]{libertinus} \usepackage{libertinust1math}% [sansmath] option destroys \upvarphi \usepackage[libertinus,biolinum,greek=up,scale=1]{libgreek} \usepackage{mathtools} \usepackage{amssymb} \renewcommand*\ttdefault{lmtt} \DeclareSymbolFont{letters}{T1}{LibertinusSans-TLF}{m}{n} \DeclareMathAlphabet{\mathit}{T1}{LibertinusSans-TLF}{m}{it} \DeclareMathAlphabet{\mathsf}{T1}{LibertinusSans-TLF}{m}{n} \DeclareMathAlphabet{\mathbf}{T1}{LibertinusSans-TLF}{b}{n} \DeclareMathAlphabet{\mathrm}{T1}{LibertinusSerif-TLF}{m}{n} % the following provides the correct sans numbers, see egreg's answer at https://tex.stackexchange.com/questions/185172/changing-number-font-into-sans-serif \DeclareSymbolFont{sfnumbers}{T1}{LibertinusSans-TLF}{m}{n} \SetSymbolFont{sfnumbers}{bold}{T1}{LibertinusSans-TLF}{b}{n} \DeclareMathSymbol{0}\mathalpha{sfnumbers}{"30} \DeclareMathSymbol{1}\mathalpha{sfnumbers}{"31} \DeclareMathSymbol{2}\mathalpha{sfnumbers}{"32} \DeclareMathSymbol{3}\mathalpha{sfnumbers}{"33} \DeclareMathSymbol{4}\mathalpha{sfnumbers}{"34} \DeclareMathSymbol{5}\mathalpha{sfnumbers}{"35} \DeclareMathSymbol{6}\mathalpha{sfnumbers}{"36} \DeclareMathSymbol{7}\mathalpha{sfnumbers}{"37} \DeclareMathSymbol{8}\mathalpha{sfnumbers}{"38} \DeclareMathSymbol{9}\mathalpha{sfnumbers}{"39} \begin{document} $\alpha\beta\pi\Pi\Delta\phi\upvarphi$ --- works $12345\text{text}67890abcDEF$ --- works $\mathnormal{12345\text{text}67890abcDEF}$ --- works $\mathsf{12345\text{text}67890abcDEF}$ --- works $\mathrm{12345\text{text}67890abcDEF}$ --- works $\mathbf{12345\text{text}67890abcDEF}$ --- works $\mathit{12345\text{text}67890abcDEF}$ --- works $\exists\forall (X\in x) [ab]+cd\rightarrow\Leftrightarrow\cup\cap\wedge\subsetneq\boxplus \{\,\} \geq\times\equiv\dots=\Cup\Cap$ --- works (although the \verb|\exists| and \verb|\forall| operators are rather ugly) \medskip $, ; . ... : < > \otimes\oplus\odot\otimes\subseteq\subset\top\bot\models$ --- \textbf{ERROR} \medskip The examples below all work: \begin{enumerate} \item \verb|$ChS_{(M)}^2$| $ChS_{(M)}^2$ should look like $\textsf{ChS}_{(\textsf{M})}^{2}$. \item \verb|$\mathit{ChS_{(M)}^\mathnormal{2}}$| $\mathit{ChS_{(M)}^\mathnormal{2}}$ should look like $\textit{\sffamily ChS}_{(\textit{\sffamily M})}^{2}$ (with proper maths kerning) \item \verb|$\mathnormal{ChS_{(M)}^2}$| $\mathnormal{ChS_{(M)}^2}$ should look like $\textsf{ChS}_{(\textsf{M})}^{2}$ \item \verb|$\mathbf{ChS_{(M)}^2}$| $\mathbf{ChS_{(M)}^2}$ should look like $\textbf{\sffamily ChS}_{(\textbf{\sffamily M})}^{2}$. \item \verb|$\mathrm{ChS_{(M)}^2}$| $\mathrm{ChS_{(M)}^2}$ should look like $\textrm{ChS}_{(\textrm{M})}^{\rm 2}$. \end{enumerate} \end{document} (I cannot add an image of the compilation result; the button is greyed out.) Comma becomes semicolon, full stop becomes colon, the less and greater symbols are wrong, and a lot of other symbol commands produce various accented letters. Curiously, if you look very closely at the semicolons and colons you will see that they are ever so slightly different between comma/semicolon and full stop/colon. I have tried to remedy this on my own, but no success so far.

\documentclass{article} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{graphicx} \usepackage{chemstyle} \usepackage{chemnum} \begin{document} \begin{scheme} \replacecmpd{first:compound} \replacecmpd{second:compound} \includegraphics[width=\linewidth]{hexa} \end{scheme} \refcmpd{first:compound}, \refcmpd{second:compound} \end{document} This works fine for referencing individual compounds. However, I would like to reference a range of compounds, e.g., "2–10". But this does not automatically translate to "2–10"; it just prints the internal labels like TMP2–10. Is there a way to make chemnum automatically output a numeric range when referencing multiple compounds? Or is there a recommended workaround to display compound ranges correctly without manually typing each number? Any guidance would be greatly appreciated.

I'm trying to produce a tagged PDF using the DocumentMetadata tagging function, but I can't get it to typeset with that key defined. I'm using TexShop version 5.57 and LuaLatex 2025.3.8. The MWE below typesets with no errors, but if I uncomment the tagging line, I get the error "LaTeX Error: The key 'document/metadata/tagging' is unknown and is being (LaTeX) ignored." How can I get the tagging key turned on? \DocumentMetadata{ lang = en, pdfstandard = ua-2, %tagging = on } \documentclass{article} \title{An Example with Document Metadata} \author{Author Name} \date{\today} \usepackage{hyperref} \hypersetup{pdftitle={A Tagged PDF Test}} \begin{document} \maketitle \section{Introduction} This document uses the new DocumentMetadata command to set accessibility and PDF standard information. \end{document}

I'm trying to create a LaTeX figure with a caption that lists multiple subitems inline, separated by semicolons, like this: \documentclass[11pt]{report} \usepackage{geometry} \usepackage{graphicx} \begin{document} \begin{figure}[h!] \centering \includegraphics[width=0.5\textwidth]{example-image-a} \caption{ \textbf{a)} aaa; \textbf{b)} bbb; \textbf{c)} ccc. } \label{fig:example} \end{figure} \begin{figure}[h!] \centering \includegraphics[width=0.5\textwidth]{example-image-b} \caption{ \textbf{a)} ddd; \textbf{b)} eee; \textbf{c)} fff. } \label{fig:example} \end{figure} \end{document} This works, but the labels (a), b), c)) are written manually. I would like to automatically generate these labels in the caption, so that if I add more items, the lettering continues (d), e), etc.), all in one line, separated by semicolons, and the last item ends with a period instead of a semicolon. My goal: Automatic a), b), c) …. Inline, separated by ; with a final . at the end. Compatible with \caption.

I am using TeXstudio 4.9.0 on Fedora Linux. Say I have the following file: \documentclass[12pt,a4paper]{article} \usepackage[margin=2cm]{geometry} \title{Title} \author{Author} \begin{document} \maketitle Hello World! \end{document} When I press F6 (Compile), compilation succeeds: Process started: pdflatex -synctex=1 -interaction=nonstopmode "test".tex Process exited normally But when I press F5 (Build & View), TeXstudio reports the following: Error: Could not start the command: Compile & View So pdflatex clearly runs and produces the PDF, but TeXstudio fails at the view stage. My Build configuration is as follows: And my Commands configuration is as follows: Any help addressing this issue would be appreciated. Note 1: I started having this problem when I activated version control: Note 2: TeXstudio now works normally again after clicking Options > Restore Default Settings.

I am trying to build my circuit diagrams containing repeating structures, leveraging the \tikzset macro and a pic inside it. For instance, for an amplifier in feedback configuration, I'd write: \tikzset{ PDCIR/.pic = { \node[myop,scale=0.8] (-O) at (0,0) {}; \node[anchor=east] at (-O.+) {$V_{cm}$}; \path ($(-O.-)+(-2,0)$) coordinate (-PDsrc); % FORCE node creation before current source \draw (-PDsrc) -- ++(0,0) to[I, l=$PD_n$, sources/scale=0.5] (-O.-); \draw (-O.out) -- ++(0,2) coordinate (-x) to[R, l_=$R_f$, resistors/scale=0.6, resistors/thickness=4] (-O.- |- -x) -- (-O.-); } } (This is a pretty convoluted version that came out during interaction with ChatGPT, my original version did not have those pre-fixed names, nor too many explicit coordinate declarations...) This and other simpler versions work fine when instantiated through: \pic[scale=0.8] at (0,-6) {PDCIR}; But break the code when I try: \pic[scale=0.8] (PDC) at (0,-6) {PDCIR}; The error is: ! Package pgf Error: No shape named `pgfcirc@resistor1467start' is known. See the pgf package documentation for explanation. Type H <return> for immediate help. ... l.119 \pic[scale=0.8] (PDC) at (0,-6) {PDCIR2} I want to label my instances so that I can refer to their anchor points, for instance the output node of the opamp inside PDCIR - I am thinking this should be some very basic and easy operation, but I am really having difficulty understanding what could possibly go wrong. Is that some sort of bug, as this answer would seem to point to?

I am using upright sans greek (Biolinum) for maths via libgreek. Everything is working fine, except that I am unable to use \varphi which gives phi in italics and, I think, in Libertinus font, so not even Biolinum.

In Word or Visio I can access the glyphs with Insert/Symbol and selecting the correct one from the character table. This is what the phi should look like: Any ideas how to do it in Tex? PS >> libgreek does not seem to have \varphi defined, so this may already be a fault of Biolinum, I guess. I need the phi in two or three places only, so a per-case solution (using the unicode id of the glyph, for example) would be fine.

I use this solution to get a shaded quotation environment---and it works marvelously, except when the quotation is to the side of a wrapfigure'd image. In such a scenario, the shading sits on top of the picture, as the following MWE shows. \documentclass[a5paper,12pt,dvipsnames*,twoside]{article} \usepackage{lipsum} % for dummy placeholders... \usepackage{graphicx} \usepackage{framed} \usepackage{quoting} \usepackage{wrapfig} \usepackage{xcolor} % --- Make quotation environment have a background colour. --- % Requires packages framed, quoting. \colorlet{shadecolor}{lightgray!20} \renewenvironment{quotation} {\begin{shaded*}\quoting[leftmargin=0pt, vskip=0pt]} {\endquoting\end{shaded*}} \begin{document} % \maketitle \date{\vspace{-10em}} \section{Introduction} \label{sec:intro} \begin{wrapfigure}{L}{0.48\textwidth} \includegraphics[scale=0.25]{dependency.png} \caption{The internet's foundations.} \label{fig:xkcd_dependency} \end{wrapfigure} \lipsum[4][1] \begin{quotation} \noindent\lipsum[4][3] \end{quotation} \end{document} My question, then, is the obvious one: how can I prevent this from happening? I.e., how can I limit the scope of shading to the length of the text? Thank you in advance for your help. EDIT: Neither the answer by @samcarter_is_at_topanswers.xyz nor that @kabenyuk work when the quoted text goes beyond the end of the image: To contrast, here is the result with the original quotation environment:

I am new to latex. I need to create a text that has a bunch of entries that have the same structure, so I thought I would create a macro for it. However there are 7 moving parts, so it needs 7 arguments. It's becoming hard to read, hard to know which argument number I'm on. So I want to name the arguments (not so much in the definition of the macro, but at least when it's used). I tried searching on the net, but found no easy solution, and it gets very quickly highly unreadable (using xparse and things like that) for non-latex experts. I found out, using luatex, I can include lua code, which seems way more readable. So I switched to luatex. The usage that I am proposing is as follows. I'm open to other usages, but it should be at least easily readable, prone to extra spaces (and newlines), and close to the latex syntax. values can themselves have newlines, and latex code (such as \textbf). curly braces (the character ending the value) should be able to be escaped in the values. \myfunction { arg1 = {value1}, arg2 = {value2}, arg3 = {value3}, arg4 = {value4}, arg5 = {value5}, arg6 = {value6}, arg7 = {value7} } The way I tried to parse it is as follows. \documentclass{article} \usepackage{luacode} \begin{luacode} function parse_args(input) local result = {} local pattern = '(%w+)%s*=%s*{%s*([^}]+)%s*}' for key, value in input:gmatch(pattern) do result[key] = value end return result end function my_function(input) local args = parse_args(input) for key, value in args do tex.print(key .. " : " .. value .. "\\") end \end{luacode} \newcommand{\myfunction}[1]{% \directlua{ my_function([===[#1]===]) }% } \begin{document} \myfunction { arg1 = {value1}, arg2 = {value2}, arg3 = {value3}, arg4 = {value4}, arg5 = {value5}, arg6 = {value6}, arg7 = {value7} } \end{document} This doesn't work, I'm getting weird issues, it seems to closing bracket in the pattern string is interpreted as latex code and I get a closing bracket error within the string. I'm open to either making my code work with minimal changes, or to provide a whole other solution, if it's elegant and easy to read.

\begin{table}[ht] \centering \setlength{\extrarowheight}{10pt} \setlength{\arraycolsep}{10pt} % \begin{tabular}{ |c|c|c|c|c|c| } \hline & $\bm{II}$ & $\bm{IX}$ & $\bm{ZI}$ & $\bm{ZX}$ & \textbf{others} \\ \hline $\bm{II}$ & $\frac{1}{4}$ & $\frac{1}{4}$ & $\frac{1}{4}$ & $-\frac{1}{4}$ & $0$ \\ \hline $\bm{IX}$ & $\frac{1}{4}$ & $\frac{1}{4}$ & $\frac{1}{4}$ & $-\frac{1}{4}$ & $0$ \\ \hline $\bm{ZI}$ & $\frac{1}{4}$ & $\frac{1}{4}$ & $\frac{1}{4}$ & $-\frac{1}{4}$ & $0$ \\ \hline $\bm{ZX}$ & $-\frac{1}{4}$ & $-\frac{1}{4}$ & $-\frac{1}{4}$ & $\frac{1}{4}$ & $0$ \\ \hline \textbf{others} & $0$ & $0$ & $0$ & $0$ & $0$ \\ \hline \end{tabular} \end{table} This is my code, but it shows that: This is not the table I want. All the fractions are not centered. I've tried many methods but none of them worked. How can I adjust it to make the table more attractive?

To make my library (robust-externalize) more robust, I need to check if a list of macro contains internal macros like \foo@bar (I may also need to do that for latex3 macros, but let's start simple). I could parse the string directly, but first I may have false positive (if an @ symbol is present, but not in a macro) and it might not be super efficient and I need super-fast code since this will be called a lot. Is it possible instead to directly check this property on the list of macro itself? MWE: \documentclass[]{article} \begin{document} \def\mylistofmacrosA{Hey \iam a normal list of \foomacro.} \def\mylistofmacrosB{Hey \iam a normal list of \foomacro with the @ symbol as a letter.} \makeatletter \def\mylistofmacrosC{Hey \iam a list of \foo@macro that contain the at symbol inside macros.} \makeatother \NewDocumentCommand{\isUsingInternalMacros}{m}{ TODO: Write "Yes" or "No" } \isUsingInternalMacros{\mylistofmacrosA} % => No \isUsingInternalMacros{\mylistofmacrosB} % => No \isUsingInternalMacros{\mylistofmacrosC} % => Yes \end{document}

How can I make the bars start at the horizontal line, instead of having a small gap between the bar and the line? (I do not need to keep the 0 mark at the y-axis.) \documentclass{article} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{width=12cm,compat=1.9} \begin{document} \begin{tikzpicture} \begin{axis}[ ymin=0, x tick label style={ /pgf/number format/1000 sep=}, enlargelimits=0.05, legend style={at={(0.5,-0.1)}, anchor=north,legend columns=-1}, ybar interval=0.7, ] \addplot[color=darkgray,fill=lightgray] coordinates { (1990,638) (1980,899) (1970,894) (1960,808) (1950,769) (1940,714) (1930,644) (1920,598) (1910,536) (1900,420)}; \end{axis} \end{tikzpicture} \end{document}

As of TexLive 2025, I started running into an error with the following MnWE: \documentclass{scrartcl} \usepackage{calc} \setcapwidth{\maxof{\textwidth}{0.8\textwidth}} \begin{document} This fails with texlive 2025. \end{document} /Volumes/Data/apps/texlive/2025/texmf-dist/tex/latex/koma-script/typearea.sty) ) (/Volumes/Data/apps/texlive/2025/texmf-dist/tex/latex/tools/calc.sty) ! Missing number, treated as zero. <to be read again> \maxof l.5 ...capwidth{\maxof{\textwidth}{0.8\textwidth}} This seems to be related to a switch to LaTeX3-style command definitions. A workaround is to precompute the value before passing it to \setcapwidth. Is there a better solutions? \documentclass{scrartcl} \usepackage{calc} \setlength{\dimen255}{\maxof{\textwidth}{0.8\textwidth}} \setcapwidth{\dimen255} \begin{document} This works. \end{document}

First, I find the LaTeX documentation lacking, in this case Tabularray Typeset Tabulars and Arrays with LATEX3. The issue as to whether I could preset certain table formats in a STY file is not covered. I am trying to setup my LaTeX template such that users who are not familiar with LaTeX, such as Word users, will find it easier to use. One thing that I thought that I could do is to preset certain formats in my STY file but I am having no such luck. I used the code, with some extras, shown on page 39 of 222 of Tabularray Typeset Tabulars and Arrays with LATEX3 in my STY file: %test \NewTblrTheme{fancy}{ \SetTblrStyle{firsthead}{bg=acornBlue, fg=white, font=\bfseries} \SetTblrStyle{firstfoot}{fg=blue2} \SetTblrStyle{middlefoot}{\itshape} \SetTblrStyle{caption-tag}{acornBlue} } I used a small code segment from their example in my TEX file (it references the STY file: \usepackage{controls}): \begin{longtblr}[ theme = fancy, caption = {A Table}, entry = {Short Caption}, label = {tblr:test}, note{a} = {It is the first footnote.}, note{$\dag$} = {It is the second footnote.}, remark{Note} = {Some general note}, remark{Source} = {Made up by myself}, ]{ colspec = {XXX}, width = 0.85\linewidth, rowhead = 1, rowfoot = 1, row{odd} = {gray9}, row{even} = {brown9}, row{1} = {acornBlue}, row{Z} = {blue7}, } \hline Head & Head & Head \\ \hline Alpha & Beta & Gamma \\ \hline Phi & Chi & Psi \\ \hline Foot & Foot & Foot \\ \hline \end{longtblr} This produces the following result: I realized that the formatting, cell colors, are overriding that specified in the STY file, so I delete them: \begin{longtblr}[ theme = fancy, caption = {A Table}, entry = {Short Caption}, label = {tblr:test}, note{a} = {It is the first footnote.}, note{$\dag$} = {It is the second footnote.}, remark{Note} = {Some general note}, remark{Source} = {Made up by myself}, ]{ colspec = {XXX}, width = 0.85\linewidth, rowhead = 1, rowfoot = 1, } \hline Head & Head & Head \\ \hline Alpha & Beta & Gamma \\ \hline Phi & Chi & Psi \\ \hline Foot & Foot & Foot \\ \hline \end{longtblr} and recompile from scratch and get the following reult: It appears that the STY file cannot be used to preset certain formats that would then free my users from having to do that for every table that they create. I tried changing \SetTblrStyle{firsthead} to: \SetTblrStyle{rowhead} and SetTblrStyle{row{1}} but got the same result. So, is the STY file supposed to allow me to preset certain table cell formats, such as bg and fg colors, etc.?

Where can I find the full list of options for \ctikzset? I couldn't find something like this in the documentation from CTAN, or in the Github repository, and for the life of me I cannot figure a consistent pattern between examples that are in the documentation. For instance if I pick up a line from examples and change it from bipoles to tripoles it sometimes works, sometimes throws and error and sometimes does nothing whatsoever. Or, otherwise, how do people figure out what the syntax for what they want to do is? As an example, the last problem I encountered that lead me to write this is adjusting the font size of transistors. Conveniently the document has the section titled Labels and Annotations under Labels, Voltages and Currents. Here it gives the example for bipoles, \ctikzset{bipole label style/.style={font=\tiny}} Which works as it should, however, it concerns bipoles only. My attempt of modifying it to: \ctikzset{tripole label style/.style={font=\tiny}} does nothing. neither does my other extrapolation attemps like quadpole, multipole, tripole/transistors, multipole/transistors, tripoles/.style, tripoles/transistors/nigfete/.style and so on. None of these do nothing and doesn't give an error either, unlike some other attemps which did give errors at least. At this point, I don't know if I'm missing the correct syntax or whether this feature exists in the first place. This happens to be my last frustration (that I'm yet to solve). However countless times in the past I have searched for similar modifications, it always boils down to finding the magic words for ctikzset and I don't know where to look. MRE \documentclass[8pt, a4paper]{article} \usepackage[american]{circuitikz} \begin{document} \begin{figure*} \begin{circuitikz} \ctikzset{bipole label style/.style={font=\tiny}} %<- From the doc. \ctikzset{tripole label style/.style={font=\tiny}} %<- My guess \draw (0,0) to[R, l=$R$] (2,0); \draw (0,2) node[nigfete]{$Q$}; \end{circuitikz} \end{figure*} \end{document}

I'd like to perfectly center a box in a page, but tikz with (current page.center) needs 2 compilations. Since this code is going to be called a lot in a library that aims precisely to improve efficiency, I'd rather optimize this. Any solution that involves only one compilation? \documentclass[beamer]{standalone} \usepackage{tikz} \begin{document} \begin{standaloneframe}% \begin{tikzpicture}[overlay, remember picture] \node[anchor=center, at=(current page.center)]{\fbox{\onslide<2>{My} content}}; \end{tikzpicture} \end{standaloneframe}% \end{document} EDIT So far no solution works for me (either not pixel-perfect, or needs too many compilations), hence I don't think this is a duplicate of the linked question. Here is what I get with @samcarter's solution (fixed since the fbox was added only to the tikz and not to his solution). \documentclass[beamer]{standalone} \usepackage{tikz} \begin{document} \begin{standaloneframe}[s] \vfill \centering\strut \fbox{My content}% \begin{tikzpicture}[overlay, remember picture,red,inner sep=0pt,outer sep=0pt] \draw (current page.south west) -- (current page.north east); \draw (current page.north west) -- (current page.south east); \node[at=(current page.center)]{\fbox{My content}\strut}; \end{tikzpicture}% \vfill \end{standaloneframe} \end{document} This kind of shift is too large for my needs as I need pixel-perfect centering (of the whole box not its baseline). And things get even worse with, e.g., a rule like \fbox{My content \rule{3cm}{3cm}}: \documentclass[beamer]{standalone} \usepackage{tikz} \begin{document} \begin{standaloneframe}[s] \vfill \centering\strut \fbox{My content \rule{3cm}{3cm}}% \begin{tikzpicture}[overlay, remember picture,red,inner sep=0pt,outer sep=0pt] \draw (current page.south west) -- (current page.north east); \draw (current page.north west) -- (current page.south east); \node[at=(current page.center)]{\fbox{My content \rule{3cm}{3cm}}\strut}; \end{tikzpicture}% \vfill \end{standaloneframe} \end{document}

Footnotes within tcolorbox followof different numbering scheme that those in regular text.

Happy Xmas all together. This question is about pgfplots, specifically about plotting line plots ins 3D. Ideally, I woudl have three x axes labelled x_1, x_2 and x_3, one y axis and one z axis (called F for force). I managned to ge the belwo MWE but from there, I am stuck (did not try ChatGPT yet!). I attached two hand drawings to show the desired outcome. It is ok to fake the three x axes as long there is a easy to understand logic / syntax. Remark: In my real world example, the y axis is reversed but I did not want to overcomplicate the question. (typo: y = -15 should say y = +15 and vice versa) \documentclass{article} \usepackage{pgfplots} \pgfplotsset{ width = \textwidth, compat = 1.18, } \begin{document} \begin{tikzpicture} \begin{axis}[ view = {60}{30}, title = {MWE}, xlabel = {$x$}, ylabel = {$y$}, zlabel = {$F$}, xmin = -30, xmax = 30, ymin = -30, ymax = 30, zmin = -100, % F zmax = 100, grid = major, axis lines = center, ] % Plots \addplot3 [ red, domain = -30:30, % for x I assume samples = 100, samples y = 1, % not sure what this does ](5,x,x^2); \end{axis} \end{tikzpicture} \end{document}

Is it possible to test if a float is at (say) the top of a page? The use case is the following: for a class I'm working on, the floating figures (are customized thanks to a floatrow style in order to) have (their captions in the left margin and) horizontal lines just above and below them and I'd like to remove e.g. the top lines of the figures that happen to be at the top of the pages (especially because there is already an horizontal line at the top of each page that separates the header and the text). Here is a MCE: \documentclass{article} \usepackage{floatrow} \usepackage{mwe} \usepackage{fancyhdr} \pagestyle{fancy} \fancyhead[L]{I'm a header} \DeclareMarginSet{hangleft}{% \setfloatmargins{\hskip-3cm}{\hfil}% } \DeclareFloatVCode{ruleabove}{% \par\rule{\hsize}{.8pt}\vskip4pt\par% } \DeclareFloatVCode{rulebelow}{% \par\vskip2pt\rule{\hsize}{.8pt}\par% } \DeclareFloatStyle{ruled}{ rowprecode=ruleabove, rowpostcode=rulebelow, } \floatsetup{objectset=justified} \floatsetup[figure]{ style=ruled, margins=hangleft, capposition=beside, capbesideposition={top,left}, floatwidth=0.85\textwidth } \begin{document} \lipsum[1-5] \begin{figure}[ht] \includegraphics[width=\linewidth]{example-image} \caption{A very very very very very very very very very very very very very very very very very very very very very long caption} \end{figure} \lipsum[1-5] \end{document}

I am processing 1000's of input where section title can contain random text. Hence I am using this set up \cprotect\section{\verb| the title read from file|} And the above works for any title (which do not ofcourse already have | in it). But why does it fail for this title below which do not have | in it? \documentclass[12pt]{article}% \usepackage{cprotect} \begin{document} %%%%%%%%%%%%%%%%%%%%% \cprotect\section{\verb|Adding footnote to the table leads to the error: !

It is easy for me to workaround this, I just add extra check in the program that the title read do not have { or } in it and remove these for now, like it does for |. I was just wondering why } can not be inside \verb when in section. It seems the parser of the section title looked at the first } inside the the closing for the section itself and not part of the inner title. TL 2025

Using TeXlive 2025/Linux, up-to-date: I expect that when I use luatexbase.add_to_callback then whatever is already in the callback should remain in effect, with my own code added. But apparently that is not the case. I have tried tweaking the callback by adding a priority number (values tried: -1000, 0, 1, 2, 1000) but no obvious difference. In this MWE, the undefined \dingle command throws an error, and the Terminal correctly informs me that the name of the undefined command is \dingle. But if I uncomment the callback, the error fails to show me the command name. Why is that? I expect that it should show the command name as usual, then perform my added function. In actual usage, I have an external *.lua file, but that makes no difference. \documentclass{article} % Compile only with lualatex. \directlua{% to see difference, uncomment the following line: % luatexbase.add_to_callback('show_error_hook', function() texio.write_nl('BOO HOO') end, 'boo_hoo') } \begin{document} Hello, World.\par % Next command is undefined, throws error: \dingle \end{document} RE-EDIT: This is in light of the accepted answer, below. In my workflow (popular fiction, no math), the writers know very little *TeX, but type (mostly) plain text into a template (custom document class). The rare need for *TeX is for things such as \textit for italics. The PDF goes to a human editor who knows no *TeX at all, but will apply highlights and sticky notes, as editors do. Then, back to the writer. Re-cycle as needed. There is no point in submitting an erroneous PDF to the editor. It wastes valuable time, if the content of the PDF was not what the writer intended. So, my custom class traps most errors and warnings, and modifies the PDF metadata if something went wrong. Then, the editor can glance at the metadata in any PDF reader, and send it back when the metadata identifies the PDF as bad. Also, I work with PDF/X-1a:2001, and the metadata conformance identifier will be omitted when an error was trapped (this is not shown here). For example, if an unknown command is typed, the error will offer the default possibility of simply ignoring the unknown command, and continuing. Sometimes ignoring the error will still produce a valid PDF, although the content of the PDF is not what the writer intended. In this example, the mis-typed \txtit can be ignored, and the PDF is valid. But its metadata producer string identifies it as BAD CODE. \documentclass{article} % Compile only with lualatex. \directlua{% badstuff = false luatexbase.add_to_callback('show_error_hook', function() badstuff = true texio.write_nl(status.lasterrorcontext) end, 'boo_hoo') } \AtEndDocument{% \def\goodresult{1}% \directlua{% if badstuff == true then tex.sprint('\\def\\goodresult{0}') end }% \ifnum\goodresult=0\relax% \pdfextension info{/Producer (BAD RESULT)}% \fi }% \begin{document} % Mis-spelled \txtit should be \textit.

I just noticed the lua-unicode-math package. Question I compile all my .tex documents using lualatex and therefore my question is as follows: What are the main differences between lua-unicode-math and unicode-math and when should I use which package?
