I am trying to get a diff between two versions of my thesis. The first command I tried using is: git latexdiff -v --main thesis.tex -o diff.pdf --flatten --latexmk --latexopt -shell-escape defended HEAD This failed. When I inspected the log, I discovered one of the errors to be: ! Missing $ inserted. <inserted text> $ l.1172 } %DIFDELCMD < }%%% I've inserted a begin-math/end-math symbol since I think you left one out. Proceed, with fingers crossed. Here is an excerpt of the diff.tex where that's from: %DIFDELCMD < \begin{minted}[breaklines]{json} %DIFDELCMD < { %DIFDELCMD < %%% \DIFdel{"interval": }%DIFDELCMD < { %DIFDELCMD < %%% \DIFdel{"start_millis": 0, "end_millis": 13 }%DIFDELCMD < }%%% \DIFdel{, "all": }%DIFDELCMD < { %DIFDELCMD < %%% And here is an excerpt form the old file thesis.tex: \begin{minted}[breaklines]{json} { "interval": { "start_millis": 0, "end_millis": 13 }, "all": { The problem appears to be that underscores were counting as a math symbol once they were taken out of the minted environment and put in a \DIFdel command. I can't just escape the underscores like \_ in the original input, because then the backslashes show up in the PDF. So I asked ChatGPT, which led me to try setting the VERBATIMLINEENV and --append-safecmd options: git latexdiff -v --main thesis.tex -o diff.pdf --flatten --latexmk --config "VERBATIMLINEENV=minted" --append-safecmd=mintinline --append-safecmd=inputminted --latexopt -shell-escape defended-fixed HEAD But that doesn't work, either. Here is one of the error messages that produces: ! Package pgfkeys Error: I do not know the key '/minted/cmd/alsolanguage', to w hich you passed 'DIFcode', and I am going to ignore it. Perhaps you misspelled it. And the diff.tex: %DIFDELCMD < \begin{minted}[breaklines]%%% %DIFAUXCMD NEXT \DIFmodbegin \begin{minted}[breaklines,alsolanguage=DIFcode] %DIF < { %DIF < "interval": { %DIF < "start_millis": 0, %DIF < "end_millis": 13 %DIF < }, %DIF < "all": { It looks like it is trying to pass the alsolanguage option to minted, which doesn't support it. I don't know if this is the fatal error that is causing the pdf not to compile. Here is the next error: ! Argument of \end has an extra }. <inserted text> \par l.1244 \end {minted} I've run across a `}' that doesn't seem to match anything. For example, `\def\a#1{...}' and `\a}' would produce this error. If you simply proceed now, the `\par' that I've just inserted will cause me to report a runaway argument that might be the root of the problem. But if your `}' was spurious, just type `2' and it will go away. I don't know if this next error is caused by the first one or not. What are my options here? I want the differences in the minted block to show up. Minimal Reproducible Example a.tex: \documentclass{article} \usepackage{minted} \begin{document} \begin{minted}{text} something_here \end{minted} \end{document} b.tex: \documentclass{article} \usepackage{minted} \begin{document} \end{document} Commands: latexdiff a.tex b.tex > diff.tex pdflatex -shell-escape diff.tex Output: ! Missing $ inserted. <inserted text> $ l.50 } %DIFDELCMD < \end{minted} ?

I noticed that when I start from a custom environment, and then decide to do something slightly non-trivial with its content (like hide it, or typeset in a different color), I end up switching to a custom macro with an argument. Consider, for example, these questions: Hide custom environment content based on boolean Environment hiding its content I have no idea how to make the content of an environment disappear without using packages like comment or version or scontents. On the other hand, this is trivial to do with a custom macro: just (re)define the macro as a no-op: \newcommand\comment[1]{}. It looks to me that any environment could be replaced with a macro, to have \theorem{...} instead of \begin{theorem}...\end{theorem}, etc. On the other hand, I do not know how to make an environment that, for example, duplicates or discards its content, or puts it in a box. What are the advantages of environments over macros that offset the inconveniences? P.S. IMO the environ package takes the correct approach.

I'm working on a document about an obscure writing system, which means I often need to insert images of the glyphs I'm talking about. So far I've been putting them inline, using the following code: \usepackage{calc} % Calculate the proper height for inline signs \usepackage{graphicx} \graphicspath{{./images/}} \newlength{\normaldepth} \makeatletter \DeclareRobustCommand{\inlinesign}[1]{% \setlength{\normaldepth}{\depthof{p}}% \raisebox{-\normaldepth}{% \includegraphics[height={\f@size pt}]{#1}% }% } \makeatother This makes them extend downward as far as a p and upward as far as a b, which is generally a good size for inline characters. However, some of these glyphs are much more elaborate than English letters, so this is sometimes difficult to see: I would like to make them extend into the inter-line spacing both above and below, to give them just a little bit more space to breathe. Since I seldom have more than three inline signs per paragraph, the odds of one being directly above another are small; I'm willing to live with the risk of that happening. How can I adjust my code to extend into the line spacing: adding twice the line spacing to the \includegraphics height, and subtracting it from the \raisebox depth? MWE: \documentclass[12pt]{article} \usepackage{calc} % Calculate the proper height for inline signs \usepackage{graphicx} \graphicspath{{./images/}} \newlength{\normaldepth} \makeatletter \DeclareRobustCommand{\inlinesign}[1]{% \setlength{\normaldepth}{\depthof{p}}% \raisebox{-\normaldepth}{% \includegraphics[height={\f@size pt}]{#1}% }% } \makeatother \begin{document} Lorem ipsum dolor sit amet, consectetur adipiscing elit.

I have defined a counter (firstcounter) and, in the first column, item numbers display as I'd expect. However, in the middle column with the same code (but a secondcounter to avoid interaction with the first list), I have changed \only<1-> to \only<1-4> and it breaks the numbering. The right hand column (with two separate counters, thirdcounter and fourthcounter), 'works' but unsatisfactorily; I feel I should not need an extra counter for each resumption of enumeration. Can someone explain to me what I'm doing wrong? \documentclass{beamer} \newcounter{firstcounter} \newcommand{\setfirst}{\setcounter{firstcounter}{\value{enumi}}} \newcommand{\contfirst}{\setcounter{enumi}{\value{firstcounter}}} \newcounter{secondcounter} \newcommand{\setsecond}{\setcounter{secondcounter}{\value{enumi}}} \newcommand{\contsecond}{\setcounter{enumi}{\value{secondcounter}}} \newcounter{thirdcounter} \newcommand{\setthird}{\setcounter{thirdcounter}{\value{enumi}}} \newcommand{\contthird}{\setcounter{enumi}{\value{thirdcounter}}} \newcounter{fourthcounter} \newcommand{\setfourth}{\setcounter{fourthcounter}{\value{enumi}}} \newcommand{\contfourth}{\setcounter{enumi}{\value{fourthcounter}}} \begin{document} \begin{frame} %left column \begin{minipage}{0.3\textwidth} \only<1->{ \begin{enumerate} \item 1st \item <2-> 2nd \item <3-> 3rd. \item <4-> 4th \setfirst \end{enumerate} } \only<5->{ \begin{enumerate} \contfirst \item 5th. \item <6-> 6th. \item <7-> 7th. \setfirst \end{enumerate} } \only<8->{ \begin{enumerate} \contfirst \item 8th. \item <9-> 9th. \item <10-> 10th. \end{enumerate} } \end{minipage} % middle column \begin{minipage}{0.3\textwidth} \only<1-4>{ \begin{enumerate} \item 1st \item <2-> 2nd \item <3-> 3rd. \item <4-> 4th \setsecond \end{enumerate} } \only<5->{ \begin{enumerate} \contsecond \item 5th. \item <6-> 6th. \item <7-> 7th. \setsecond \end{enumerate} } \only<8->{ \begin{enumerate} \contsecond \item 8th. \item <9-> 9th. \item <10-> 10th. \end{enumerate} } \end{minipage} % right column \begin{minipage}{0.3\textwidth} \only<1-4>{ \begin{enumerate} \item 1st \item <2-> 2nd \item <3-> 3rd. \item <4-> 4th \setthird \end{enumerate} } \only<5->{ \begin{enumerate} \contthird \item 5th. \item <6-> 6th. \item <7-> 7th. \setfourth \end{enumerate} } \only<8->{ \begin{enumerate} \contfourth \item 8th. \item <9-> 9th. \item <10-> 10th. \end{enumerate} } \end{minipage} \end{frame} \end{document} These are all the same lists and should have the same numbering.

The pdf produced by the first example below is much larger (3x) than that of the second. Both are PDF version 1.7, and neither are tagged (according to pdfinfo). What accounts for the difference in size, and can the pdf of the the first example be made smaller with another argument to DocumentMetadata? \DocumentMetadata{pdfversion=1.7} \documentclass{article} \begin{document} \section{One} This is section one. \section{Two} This is section two. \end{document} \documentclass{article} \begin{document} \section{One} This is section one. \section{Two} This is section two. \end{document}

I noticed what appears to be a clash between cleveref and empheq packages when I define labels for cleveref so that references to inequalities are labelled as such and not as equations. Consider the following MWE: \documentclass{article} \usepackage{empheq} \usepackage{cleveref} \crefname{ineq}{ineq}{ineqs} \begin{document} \begin{equation} \label[ineq]{label1} % \label{label1} a < b \end{equation} \cref{label1} \end{document} It produces LaTeX Warning: Reference `label1' on page 1 undefined on input line 15. and Now if I comment \usepackage{empheq}, the warning disappears and the correct output is generated: Alternatively, if I comment \label[ineq]{label1} and uncomment \label{label1}, the warning also disappears, but then the inequality is incorrectly labelled as an equation: The conclusion is that there is a clash between cleveref when labels are defined and empheq. (In my document, I need empheq to label individual equations in the cases environment.) How can I resolve or work around this problem? (I'm running pdfTeX, Version 3.141592653-2.6-1.40.28 (TeX Live 2025) on macOS Sequoia 15.7.1.)

I'm using xsim with the following: \renewcommand\printsolutions{% \def\currentchapter{}% \def\currentsection{}% \def\lastchapter{}% \def\lastsection{}% \ForEachUsedExerciseByType{% \let\lastchapter\currentchapter \let\lastsection\currentsection \edef\currentchapter{\ExercisePropertyGet{##1}{##2}{chapter-value}}% \edef\currentsection{\ExercisePropertyGet{##1}{##2}{section-value}}% \ifx\lastchapter\currentchapter\else \section*{Poglavlje \ExercisePropertyGet{##1}{##2}{chapter}} \fi \ifx\lastsection\currentsection\else \subsection*{Zadatci \ExercisePropertyGet{##1}{##2}{section}} \fi \XSIMprint{solution}{##1}{##2}% }% } which does exactly what I want - prints solutions where I need them to be, grouped by chapters and sections: However, not all exercises have solutions. In fact, there are sections with no solutions at all, leading to empty groups like for example "Zadatci 0.4". I would like to avoid empty collection, i.e. when there are only unsolved exercises in particular section, then that section should not appear in \prinsolutions. My guess is that \IfExistSolutionTF command should be used, but am not so proficient to make that work.

I often work on two closely related TeX documents at the same time and would like to place one TeXstudio editor window on each of my two displays. However, on macOS, TeXstudio opens multiple .tex files as tabs within a single window rather than in separate windows. Is there a way to open multiple TeXstudio editor windows or run multiple TeXstudio instances on macOS? I am using TeXstudio 4.9.1 on macOS Tahoe 26.2.

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}

I am trying to create a cover image for my ebook, but it actually creates it twice: as a cover, and then again as a first page in the document followed even with text on the same page. Following the proposal here: Need to avoid duplication of cover image in Kindle book (tex4ebook) I tried to update my cfg file accordingly, but it still doesn't work for me. So probably I still make a mistake somewhere. How should the cover image be properly defined? Here is an MWE: \documentclass{book} \usepackage{graphicx} \usepackage{tex4ebook} \begin{document} \thispagestyle{empty} \coverimage{cover.png} \newpage \textbf{This text should be shown on a new page after the cover image. However, while a cover is created, the same image from the cover is then shown a second time on page 1 with this text right below.} \tableofcontents \chapter{Chapter 1} Some text. \chapter{Chapter 2} More Text. \end{document} And here the config-file: \Preamble{xhtml} \special{t4ht+@File: cover.png} \CoverMetadata{cover.png} \begin{document} \EndPreamble

I would like to reproduce the following commutative diagram, consisting of square boxes with mathematical expressions located near the corners, rather than mathematical expressions connected by an arrow. Since this type of diagram only develops vertically, as if it's a single column, I think it is possible to create a command that uses TikZ to draw a square and accepts four arguments, one for each edge of the square. However, I am having difficulty stacking these squares. Can you help me? Thank you EDIT: These are the instructions I'm using for making the square box. These are normally located inside a command that takes four argument, one for each corner. \begin{tikzpicture} \draw[thick] (0,0) rectangle (2,2); \node[left] at (0,2) {$f(t)$}; \node[left] at (0,0) {$e^{at}f(t)$}; \node[right] at (2,2) {$F(s)$}; \node[right] at (2,0) {$F(s-a)$}; \end{tikzpicture} These result in the following figure:

A few years ago I asked a question in this forum about how to format today's year per the Hebrew calendar with polyglossia. I received an answer that I was happy with at the time, and therefore accepted it. However, now when I try to run the code provided in that answer (by storing the code in a file named Main.tex, and running the command xelatex Main.tex), the compilation fails, and I get the following error message: ! Undefined control sequence. \HebrewYearName ... =#1\relax \if@hebrew@fullyear \else \advance \@tempcnta ... l.74 \ThisHebrewYear Why does the compilation fail, when it used to compile successfully? How can I fix it? P.S. I use MikTex on Windows 11 Pro. I don't know what version of MikTex is in use. (BTW, how can I find out what version of MikTex I'm using?)

I'm trying to compile a LaTeX document that I wrote several years ago, and that used to compile successfully with lualatex. The document and its preamble are very long, but I managed to cut them down to the bare minimum that shows the problem I face while compiling the original document. \documentclass{scrbook} \usepackage{fontspec} \usepackage{unicode-math} \setmathfont{XITS Math} \begin{document} Hello world \end{document} The above code is stored in a file named Main.tex. When I run the command lualatex Main.tex, the compilation fails, and the following error message appears near the end of Main.log. ! Package fontspec Error: (fontspec) The font "XITS Math" cannot be found I tried compiling Main.tex using pdflatex instead, but this too failed. Why does the compilation fail? How can I fix the problem? P.S. I use MikTex on Windows 11 Pro. I don't know how to check which MikTex version I use.

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 .. ' (this parenthetical indicates that the translit function ran)' end return exports \documentclass{article} \usepackage{biblatex} \directlua{tr = require("transliteration.lua")} \begin{filecontents}[overwrite]{test.bib} @misc{test, author = "aa", title = "bb", year = 2020} \end{filecontents} \addbibresource{test.bib} \DeclareCiteCommand{\translitciteauthor}{}{\directlua{tex.print(tr.transliterate("\\printnames{author}"))}}{}{} \begin{document} 1 % runs function but does not transliterate % additionally, if including babel and using an RTL script, this throws a "missing number, treated as zero" \directlua{tex.print(tr.transliterate("\\citeauthor{test}"))} 2 % runs function but does not transliterate \directlua{tex.print(tr.transliterate("\\expandafter{\\citeauthor{test}}"))} 3 % does nothing \latelua{pdf.print(tr.transliterate("\\citeauthor{test}"))} 4 % runs function but does not transliterate \translitciteauthor{test} \end{document}

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.

How do I choose the anchor so that the line starts exactly at the edge at a path-source to[american current source]? \documentclass[margin=5pt, multi=circuitikz]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[] %\ctikzset{bipoles/border margin=0.0}% no effect \draw[] (0,0) to[american current source, o-o, name=GS] (2,0); \draw[->] (GS.north east) -- +(45:1); \end{circuitikz} \end{document}

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.

Suppose I am writing an exercise with a amsart enviroment like the one shown in the MWE below, \documentclass[12pt,a4paper]{article} \usepackage{geometry} \usepackage{amsmath} \usepackage{amssymb} \begin{document} Studiare in $(0, 0)$ la continuità, l'esistenza delle derivate parziali e la differenziabilità della funzione \[ f(x, y) = \begin{cases} \dfrac{x^3 + 3x^2y + y^4}{x^2 + y^2} & \text{se } (x, y) \neq (0, 0) \\ 0 & \text{se } (x, y) = (0, 0). \end{cases} \] Studiamo la continuità in $(0,0)$. 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. I'm searching something without use tcolorbox (mdframed or similar) using simple commands (without package) to create an "oblique rule" .

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 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.
