The following M(not)WE fails because of the \Cdots used. Is there a quick fix of this bug? The log file indicates the error below if I uncomment the failing sub matrix command. Package nicematrix Error: Impossible delimiter. (nicematrix) It's impossible to draw the right delimiter of (nicematrix) your \SubMatrix because all the cells are empty (nicematrix) in that column. (nicematrix) This \SubMatrix will be ignored.

While using [spanish]babel with a KOMA-script class (I've tried with scrartcl and scrbook) I get the following error: LaTeX hooks: Generic hooks cannot be added to '\@startsection'. How can I fix this? Here is my MWE. \documentclass{scrartcl} \usepackage[spanish]{babel} \begin{document} Buenos días. \end{document}

For quite some span of time, I was sure to have solved that problem. I got the build time from the original PDF file, e.g. via pdfinfo. Then i made the next build with SOURCE_DATE_EPOCH using exactly that time. Also FORCE_SOURCE_DATE must be set. This worked with lualatex and PDF 1.7. Now, adding pdfa/A, tagging, PDF/UA and moving on to PDF2.0, it does not work any more. Some experiments show, the critical feature is tagging. It is a great feature and i dont want to do without it. I search for a way to keep reproducibility even if tagging is present. Well, in fact, reproducibility is no longer trustable, sometimes it works. I observe that sometimes the lengths of the files differ minimally. Visually, they are the same, also XMP data seems the same. But my old simple concept of bytewise equivalence is gone. I tried with uncompress as suggested by DavidCarlisle, << /Type /Namespace /NS (data:,AC8956-1B7-A6A9-1928-C381ECC1E1C) >> << /Type /Namespace /NS (data:,5F48FB81-AC9C-B85B-A0B9-890FA89F45CC) >> is the first difference. The next is in a sequence of xref 0 17537 0000000002 65535 f 0007003671 00000 n 0000000003 00000 f But i cannot interprete these... and remarkable that even the trailer IDs coincide. In my dark thougths I even read the PDF spec and found that the trailer ID may depend on the location of the PDF also... So maybe there is another problem I do face only if there are more developers compiling in different environments. Maybe latex compilers dont use location to create the trailer ID, do they? Any advice on a sound foundation for reproducibiliby also in the future? Future is >PDF1.7, and PDF/A, PDF/UA, including tagging.

Is there a reference on how to make tables better, or a more standard way of pre-contemplating them? I was trying to tabulate the elementary linear transformations, and noticed that my table was rather unaesthetic. My hope is that someone could guide me on how I could better pre-contemplate these tables, so that they don't come out looking like this: \documentclass[letterpaper]{book} \usepackage{nicematrix} \usepackage{booktabs} \usepackage{tikz} \usepackage{microtype} \usepackage{mathtools} \usepackage{unicode-math} \newcommand{\temp}{% \begin{tikzpicture} \draw (-1,-1) rectangle (1,1); \node at (0,0) {Blah.}; \end{tikzpicture}% } \begin{document} \begin{table} \centering \begin{tabular}{lll} \toprule Linear transformation & Example Matrix & Geometric effect \\ \midrule Scale & \({\begin{bNiceArray}{cc} t & 0 \\ 0 & 1 \end{bNiceArray}}\) & \temp \\ \midrule Shear & \({\begin{bNiceArray}{cc} 1 & t \\ 0 & 1 \end{bNiceArray}}\) & \temp \\ \midrule Swap & \({\begin{bNiceArray}{cc} 0 & 1 \\ 1 & 0 \end{bNiceArray}}\) & \temp \\ \bottomrule \end{tabular} \caption{The elementary matrices are blah blah blah.} \label{table:chap-elem-mat} \end{table} \end{document}

Activating line numbers on a latex document, causes text highlighted using the \hl command to disappear.

I want to automatically transliterate titles and author names I'm citing if they're written in another script. For example, given an author named مَحْمُود, I would like to be able to cite them inline as "(مَحْمُود maḥmūd 2020)". Supposing this author wrote a paper titled أَبْجَد هَوَّز, I would like to be able to cite it inline as "أَبْجَد هَوَّز ʾabjad hawwaz (مَحْمُود maḥmūd 2020)". Ideally the compiled bibliography should show these transliterations as well. I've written a Lua module transliteration.lua that exports a function transliterate() such that, for example, transliterate('مَحْمُود') returns the string 'maḥmūd'. However, I can't figure out where or if it's even possible to call my transliteration.transliterate() function within my paper in order for it to correctly apply to biblatex citations. This seems to interact in a complex way with the need to compile multiple times in order to format references correctly. Is there a combination of control sequences and compilation steps that will net exactly the citation formats I've described above? Is there a low-level way to override how names and titles and such are generated such that I can continue to use the default \cite(s), \parencite(s), \autocite(s), \citeauthor, etc. commands without redefining my own? This differs from prior transliteration questions like Auto transliteration in that I don't wish to directly write text in the other script. A question that seemed related was biblatex: Use field value in tex document before compilation but I couldn't figure out how to apply it to my situation. Below is a non-functioning example that demonstrates a rudimentary (and incorrect) understanding of \latelua, \expandafter, \DeclareCiteCommand, etc. (For demonstration, this is generic string substitution without reference to a specific script except in the comment about babel.) I am compiling this with the VSCode Latex Workshop extension's latexmk (lualatex) recipe, which as of writing runs latexmk -synctex=1 -interaction=nonstopmode -file-line-error -lualatex -outdir=%OUTDIR% %DOC%. -- transliteration.lua local exports = {} exports.transliterate = function(text) text = text:gsub("bb", "cc") text = text:gsub("aa", "bb") return text ..

I was wondering why there's a different polarity used in EU vs american symbols for voltage sources. As one can see the eu version and the american version have oposite polarity, which make's it hard once you start mixing circuits with a EU base and american base. example: \documentclass[a4paper,11pt]{article} \usepackage{circuitikz} \usepackage{siunitx} %\sisetup{locale = DE} % komma als decimaalteken (optioneel) \begin{document} \begin{circuitikz}[american] \draw (0,0) to[V=10V] (2,0); \end{circuitikz} \begin{circuitikz}[european] \draw (0,0) to[V=10V] (2,0); \end{circuitikz} \begin{circuitikz} \draw (0,0) to[V=10V] (2,0); \end{circuitikz} \end{document} So I get a polarity swap between EU and american If a read the manual it should not invert (image/code 1 vs 3 )

I am making the following table using LaTeX. One way to do it is to make a separate row for the "Top Header" header. However, this results in space below that header and the "sub headers": \documentclass{article} \usepackage{booktabs} \begin{document} \begin{table} \centering \begin{tabular}{ll rr} \toprule (1) & (2) & (3) & (4) \\ \midrule & & \multicolumn{2}{c}{Top Header} \\ \cmidrule(lr){3-4} Main & Main & \\ Header 1 & Header 2 & Sub 1 & Sub 2 \\ \midrule 0.01 & 0.25 & 0.05 & 0.00 \\ 0.02 & 0.25 & 0.11 & 0.03 \\ 0.05 & 0.25 & 0.16 & 0.09 \\ \bottomrule \end{tabular} \end{table} \end{document} An alternative way is to include "Top Header" on the same line as the top line of the "Main Headers", but the use of \cmidrule creates awkward space for the two "Main Headers": \documentclass{article} \usepackage{booktabs} \begin{document} \begin{table} \centering \begin{tabular}{ll rr} \toprule (1) & (2) & (3) & (4) \\ \midrule Main & Main & \multicolumn{2}{c}{Top Header} \\ \cmidrule(lr){3-4} Header 1 & Header 2 & Sub 1 & Sub 2 \\ \midrule 0.01 & 0.25 & 0.05 & 0.00 \\ 0.02 & 0.25 & 0.11 & 0.03 \\ 0.05 & 0.25 & 0.16 & 0.09 \\ \bottomrule \end{tabular} \end{table} \end{document} A third way, with no \cmidrule gets the vertical spacing right, but I do want a to use \cmidrule to get a line under "Top Header": \documentclass{article} \usepackage{booktabs} \begin{document} \begin{table} \centering \begin{tabular}{ll rr} \toprule (1) & (2) & (3) & (4) \\ \midrule Main & Main & \multicolumn{2}{c}{Top Header} \\ Header 1 & Header 2 & Sub 1 & Sub 2 \\ \midrule 0.01 & 0.25 & 0.05 & 0.00 \\ 0.02 & 0.25 & 0.11 & 0.03 \\ 0.05 & 0.25 & 0.16 & 0.09 \\ \bottomrule \end{tabular} \end{table} \end{document} How can I get columns 1 and 2 to behave as in the first table, but columns 3 and 4 to behave as in the second table? In other words, I'd like the headers to take up two lines, as in the second table, and I'd like to use the \cmidrule command for columns 3 and 4, but I don't want the the extra space in between "Main" and "Header 1" and "Main" and "Header 2" that we see in the second table.

I found that the behaviour of the voltage/distance from node-key varies depending on the component, as can be seen in the mwe below. Is there a fix that I am missing? Also, when I set voltage/distance from node=0 there is still some distance to the actual center of the node (marked in red). I have no idea where this is coming from (maybe a TikZ-thing?). I thought, maybe the inner sep of the nodes was not being accounted for, but after some testing, I found that the distance differs from the standard inner sep of nodes. Does someone have an idea? \documentclass{standalone} \usepackage{tikz} \usepackage[straightvoltages]{circuitikz} \begin{document} \begin{tikzpicture} \draw (0,0) to[R,name=R,v=U,voltage/distance from node=0] (2,0); \draw (0,-1) to[open,name=v,v=U,voltage/distance from node=0] (2,-1); \draw (0,-1.25) to[open,v=U,voltage/distance from node=0,open voltage position = legacy] (2,-1.25); \draw[red] (0,0 |- R-Vfrom) -- (R-Vfrom) node[midway,below] {?}; \draw[red] (0,-1) -- (v-Vfrom) node[midway,below] {?}; \end{tikzpicture} \end{document}

If the content is varied so that different ``cells'' have different heights the horizontal alignment of the array of aligned environments no longer aligns grid rows.

Related: This question follows from my previous one about dynamic page margins, where flowfram was suggested as a solution approach from MS-SPO @ms-spo. I'm trying to use the flowfram package to create a LaTeX document with different page layouts matching different background PDFs, as suggested in this comment on my previous question. My setup works well except for one issue: when a paragraph spans across pages with different frame widths, the text on the new page continues using the previous page's frame width, causing misalignment; please see the png attachment! MWE: \documentclass{article} \usepackage{lipsum} % ===== Load packages ===== \usepackage[margin=0pt]{geometry} % Disable geometry's margin control \usepackage{eso-pic, graphicx} \usepackage{flowfram} % ===== Define three page layouts ===== % 1.

Odd pages layout (except first) \newflowframe[3,5,7,9,11,13,15,17,19,21,23,25,27,29,31]{% \dimexpr\paperwidth-66mm\relax}{% width \dimexpr\paperheight-70mm\relax}{% height 62mm}{% left (x-coordinate) 38mm% top (y-coordinate from bottom) }[oddpage] % 3.

What I've tried: The flowfram manual mentions using \framebreak to handle this: "If the flow frames are not all of the same width, the change in \hsize will not come into effect until the end of the paragraph. Provide a command to simulate a paragraph break..." However, I'm not sure: Where to insert \framebreak (at potential break points? automatically?) How to use it properly (the manual mentions grouping for \parfillskip and \parskip) If there are better alternatives for handling this Questions: How should \framebreak be used in practice to fix cross-page paragraph width issues? Is there a way to automate this, or must I manually insert break points? Are there alternative approaches within flowfram to handle different frame widths across pages? automatically?

MWE: \documentclass[12pt]{article} \textwidth=3.5in \begin{document} \thispagestyle{empty} \begin{equation} \left( \frac{A}{B} \right) \end{equation} \vspace{35pt} \noindent How to enclose text extending over multiple lines with parentheses (\emph{as if} it were a fraction)? \end{document} The output: I would like to enclose text which extends over two or more lines by an appropriately sized set of parentheses. I have tried using \left( and \right) as if I were in a mathematical environment, such as shown in in the fractional expression. However, this does not work when in a text environment. Using $...$ does not help either. How may I enclose the given text, which extends over two lines, entirely with one set of appropriately sized parentheses?

The motivation Pfaff, Johann Friedrich: Methodus generalis, aequationes differentiarum partialium, nec non aequationes differentiales vulgares, utrasque primi ordinis inter quotcunque variabiles, complete integrandi The Problem \documentclass[a4paper,10pt]{article} \usepackage{amsmath} \usepackage{mathtools} \usepackage{unicode-math} \setmainfont{STIX Two Text} \setmathfont{STIX Two Math} \newcommand{\tprime}{\char"2034} % ‴ \newcommand{\qprime}{\char"2057} % ⁗ \begin{document} Prime notation: $x^{\prime},x^{\dprime},x^{\tprime},x^{\qprime}$ \end{document} Obviously, the desired result would be for the triple prime to look like the double prime with one more prime, and to look like the quadruple prime with one less prime. This appears to be a feature of unicode since it appears in browsers, in Kate, in Emacs, (differently un-uniform) in xterm. Is there a way to produce a uniform set of prime, double prime, triple prime, quadruple prime using LuaLaTeX? Preferably with STIX Two. Post Script. I was unaware that $x'''$ would work. I learned to author LaTeX using LyX which is WYSIWYM not WYSIWYG. I rarely compiled what I was writing. My reality was what I saw in LyX.

I ask this question only out of curiousity's sake. I am not actually planning on defining a new command called \cmd because the usual \cs macro has superior syntax. (\cmd<command name, including backslash> and \cs{<command name, omitting backslash>} would print the name of a command.) When defining and testing \cmd, I found a strange error where \cmd\par would issue an error even if \cmd is \long (+m in \NewDocumentCommand). So I think that the argument should accept \par tokens. After some trial and error, I randomly changed \texttt to \ttfamily and the error went away. My question is: Why did this fix the error? I don't understand why \texttt wouldn't work correctly in this case. I provide a MWE below to demonstrate the issue: \documentclass{article} \ExplSyntaxOn \NewDocumentCommand \cmdtesti { +m } { \__module_cmd_test_i:N #1 } \cs_new_protected:Npn \__module_cmd_test_i:N #1 { \group_begin: \ttfamily \token_to_str:N #1 \@ % works correctly when #1 is \par \group_end: } \NewDocumentCommand \cmdtestii { +m } { \__module_cmd_test_ii:N #1 } \cs_new_protected:Npn \__module_cmd_test_ii:N #1 { \texttt { \token_to_str:N #1 \@ } % This gives an error if #1 is \par. } \ExplSyntaxOff \begin{document} \cmdtesti\command % no error \cmdtestii\command % no error \cmdtesti\par % no error % \cmdtestii\par % gives an error % \cmdtestii{\par} % gives an error \end{document}

Si ha \[ |f(x,y)| = \left| \frac{x^3 + 3x^2y + y^4}{x^2+y^2} \right| \leq |x|+3|y|+|y|^2 \] e quando $(x,y)\to(0,0)$ l'ultima diseguaglianza tende a $0$ e anche la funzione di partenza lo sarà. Quindi \[ \lim_{(x,y)\to(0,0)} f(x,y) = 0 = f(0,0), \] cioè $f$ è continua in $(0,0)$. \end{document} and I want to strike out the entire exercise, while preserving any environments created with amsart, as in the image below.

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?

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 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?

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}
