I now have a file with the following contents. Normally, I can run pdflatex main to compile. When compiling for the second time, the previous auxiliary file will be loaded, and everything is normal. I have a clear demand now, that is, by configuring latexmkrc file, when running latexmk command, it is the same as running pdflatex main directly. At present, when running latexmk, the default rule will be triggered, resulting in that even if running latexmk for the second time, the directory will not be generated. % main.tex \documentclass{article} \begin{document} \tableofcontents \section{111} \subsection{222} \section{333} \end{document} $pdf_mode = 1; $max_repeat = 1; @default_files = ('main'); >latexmk Initial Win CP for (console input, console output, system): (CP936, CP936, CP936) I changed them all to CP936 Rc files read: latexmkrc Latexmk: This is Latexmk, John Collins, 15 June 2025.

However, the scene I have encountered at present is that I can only execute latexmk command, so I need to configure latexmkrc file to achieve the same effect.

I want a smartly breakable longtblr, but I have to manually assign a breaking point now.

My problem is that in a two-column book, when the marginnote is placed as the last word (or near the last word) of the left column line end, the note jumps to the right margin instead of being placed on the left margin.

My goal for the new year is to learn how to add and multiply numbers in tikz.

I would like to give two case-based equations and have them aligned. I've tried several different ways of doing it and always end up with something like this: \begin{equation}\begin{aligned} A & = \left\{\begin{matrix} bb \, , & q=0 \\ c \, , & q\ge1 \end{matrix}\right. \\ D & = \left\{\begin{matrix} ee \, , & q=0 \\ f \, , & q=1 \\ gggggg \, , & q\ge2 \end{matrix}\right. \end{aligned}\end{equation} The issue is that I want to have the bracket outside the matrix, so it can fit the size of the separate cases, and I also want to have the conditions aligned with one another, but I cannot do this unless they are not separated into two matrices for the brackets. I also need to have the expressions on the left side of the cases centered properly. Also, I would like to have the different cases to be left-aligned How can I have all three - the centered expressions on the left with properly-sized brackets, the aligned conditions, and the left-aligned cases?

I want to draw a square in LaTeX where the inside has a watercolor-like fill and a hand-drawn appearance. Is it possible to draw this with LaTeX?

The unicode-math package re-defines ellipsis to be the ellipsis character in whatever font you're using, instead of spaced dots. This looks bad in my opinion, and violates the guidance on ellipses in every style guide I own. A solution for \ldots is provided here: variations-in-ldots. But that solution does not fix \cdots, \vdots, or \ddots. I managed to find a solution for \cdots that works in this MWE, but seems to fail in other instances that I haven't figured out a reliable way to reproduce. And I can't figure out a solution for \vdots or \ddots at all. \documentclass{article} \usepackage{unicode-math} \AtBeginDocument{ % From https://tex.stackexchange.com/questions/120627/variations-in-ldots \renewcommand\mathellipsis{\mathinner{\ldotp\ldotp\ldotp}} \renewcommand\cdots{\mathinner{\cdotp\cdotp\cdotp}} % sometimes works %\renewcommand\vdots{\mathinner{\vdotp\vdotp\vdotp}} % doesn't work %\renewcommand\ddots{\mathinner{\ddotp\ddotp\ddotp}} % doesn't work } \begin{document} $\dots, \ldots, \cdots, \vdots, \ddots$ \end{document} Found an example of where my solution for \cdots didn't work. It's when \dots is used instead of \cdots explicitly to centrally place dots: \documentclass{article} \usepackage{unicode-math} \AtBeginDocument{ \renewcommand\mathellipsis{\mathinner{\ldotp\ldotp\ldotp}} \renewcommand\cdots{\mathinner{\cdotp\cdotp\cdotp}} % sometimes works } \begin{document} $x+\dots+ y$ % Do not get spaced dots $x+\cdots+ y$ % Do get spaced dots \end{document}

For the graphics I use on my physics exercise sheets made with TikZ I often use the same objects (hooks, masses, carts, pulleys, force gauges,...). So instead of copy-pasting and modifying the code of these objects I think it makes sense to make them into a ready to use object. There are three ways I know of to make that happen: TeX macros, pics and shapes. There are some features I wish the implementation of these objects to have and need some advice on how to implement it in order to have those features: An object should have multiple anchors so I can easily use certain points for further construction and choose which anchor to use for the placement (so there is no need to calculate that stuff manually). The hook for example could be placed at it's base or the actual hook and either one should be available afterwards for further placement of objects or paths. A default style should be set, i.e. the fill color or shading of the mass body, that can be overwritten. If placed inside a scope that changes shift, rotation, scale, line width,... these changes should automatically also apply to the object as a whole. I want to be able to construct new objects from already existing objects, i.e. I want to be able to use the hook as part of the mass, force gauge and cart. Right now I'm leaning towards defining new shapes, even tho I haven't used low level pgf before. As far as I can see 1 and 3 are no problem with shapes. I feel like 2 could also be achieved (any hints are appreciated - maybe defining a new style that uses that shape?). I however have no Idea if or how to make 4 work in defining a new shape. Pics on the other hand would make 2 and 4 easy as far as I can imagine. But they don't respond to the settings of a scope (3). Also anchors (1) are not natively supported but using tikzmark one answer to this question Anchoring TiKZ pics suggests this could be achieved as well (although I imagine it to be not quite as powerful as a new shape and takes two compilation runs if I understood correctly). Any thoughts, hints or pieces of advice are very welcome. I hope I described the setting clear enough. Edit The following Example is not meant to be beautiful but hopefully helps to illustrate the issue: \documentclass[tikz]{standalone} \usetikzlibrary{calc} \usetikzlibrary{tikzmark} \begin{document} \tikzset{ hook/.pic={ \draw[double=gray!80, double distance=1.4pt] (0,0) .. controls (0,-1.5) and (0,{1/sin(45)-2.5}) .. ($(45:1)+(0,-2.5)$) arc(405:140:1); \node[inner sep=2mm] (-hole) at (0,-2.5) {}; } } \tikzset{ cart/.pic={ \shadedraw[left color=blue, right color=blue!50] (-3,0) rectangle (3,2); \shadedraw[left color=black, right color=gray] (2,-.8) circle (.8); \shadedraw[left color=black, right color=gray] (-2,-.8) circle (.8); \pic[transform shape,rotate=90,scale=.5] (h) at (3,1) {hook}; \coordinate (-front-wheel) at (2,-1.6); \coordinate (-back-wheel) at (-2,-1.6); \node[inner sep=2mm] (-hook) at (h-hole) {}; } } \begin{tikzpicture} \draw (0,0) -- (8,0) -- (8,2); \pic[pic anchor=(-back-wheel),scale=.5] (cart) at (.5,0) {cart}; \pic[rotate=270,xscale=-1,scale=.25] (hook) at (8,0|-cart-hook) {hook}; \draw[ultra thick, line cap=round] (cart-hook) -- (hook-hole); \end{tikzpicture} \end{document} So using a pic with tikzmark (and transform shape as I've discovered) seems to check all the requirements. Can this also be achieved with a custom shape? As in this solution I dislike a few things: tikzmark needs two compilation runs no border anchors can be defined (at least I don't know how) It seems to me all anchors are defined every time a pic is inserted and not calculated when needed as with shapes. I'm not sure about the impacts on compilation time.

Task Consider the following: One needs to store a over time varying amount of pgfkeys entries with a nested data structure. All the entries have the same structure, but the content may vary. So one defines a macro to handle the pgfkeys structure initialization automatically when the user sets the data. Artificial Example: Inventory (MWE) \documentclass[parskip=full]{scrreprt} \usepackage{pgffor} \usepackage{pgfkeys} % DESCRIPTION: Set up inventory entries manually \pgfkeys{ /handlers/.is setter/.code=\pgfkeysedef{\pgfkeyscurrentpath}{% \noexpand\pgfqkeys{\pgfkeyscurrentpath}{##1}% },% /inventory/.cd, Manual 5 Speed/.is setter, Manual 5 Speed/inventory id/.initial = XXXXXXXXXX, Manual 5 Speed/product/.is setter,% Manual 5 Speed/product/manufacturer/.initial = EMPTY, Manual 5 Speed/product/product id/.initial = EMPTY, Manual 6 Speed/.is setter, Manual 6 Speed/inventory id/.initial = YYYYYYYYYY, Manual 6 Speed/product/.is setter,% Manual 6 Speed/product/manufacturer/.initial = EMPTY, Manual 6 Speed/product/product id/.initial = EMPTY } % DESCRIPTION: Logic for creating pgfkey "database" entry automatically and setting them to user specified data % ARGUMENTS: #1 = entry product, #2 = entry data \newcommand{\generateEntry}[2]{ % DESCRIPTION: Creating the pgfkeys "family" and intialize with default values \pgfkeys{ /handlers/.is setter/.code=\pgfkeysedef{\pgfkeyscurrentpath}{% \noexpand\pgfqkeys{\pgfkeyscurrentpath}{##1}% },% /inventory/#1/.cd, inventory id/.initial = ZZZZZZZZZZ, product/.is setter,% product/manufacturer/.initial = EMPTY, product/product id/.initial = EMPTY } % DESCRIPTION: Setting the data to the one specified by the user \pgfqkeys{/inventory/#1}{#2} } % DESCRIPTION: Macro for testing whether it is a problem with wrapping \pgfqkeys in an additional macro \newcommand{\setEntryData}[2]{ \pgfqkeys{/inventory/#1}{#2} } \begin{document} % DESCRIPTION: Setting the data of the manually added entry % with \pgfqkeys and "{}" notation % STATUS: WORKS AS EXPECTED \pgfqkeys{/inventory/Manual 5 Speed}{ inventory id = 6, product = { manufacturer = Herbert Motors, product id = 433M5 } } % DESCRIPTION: Setting the data of the manually added entry % with \pgfqkeys wrapped in macro and "{}" notation % STATUS: WORKS AS EXPECTED \setEntryData{Manual 6 Speed}{ inventory id = 11, product = { manufacturer = Herbert Motors, product id = 433M6 } } % DESCRIPTION: Generate and set data for automatic entry % with "/" notation % STATUS: WORKS AS EXPECTED \generateEntry{Automatic 4 Speed}{ inventory id = 21, product/manufacturer = Jane's Speedshop, product/product id = JS4A } % DESCRIPTION: Generate and set data for automatic entry % with "{}" notation % STATUS: FAILS FOR NESTED KEYS \generateEntry{Automatic 5 Speed}{ inventory id = 42, product = { manufacturer = Jane's Speedshop, product id = JS5A } } % DESCRIPTION: Visualize the data stored in the pgfkeys \section*{Inventory} \foreach \entry in {Manual 5 Speed, Manual 6 Speed, Automatic 4 Speed, Automatic 5 Speed}{ \textbf{\entry}:\\ inventory id: \pgfkeysvalueof{/inventory/\entry/inventory id}\\ manufacturer: \pgfkeysvalueof{/inventory/\entry/product/manufacturer}\\ product id: \pgfkeysvalueof{/inventory/\entry/product/product id} \\[0.25cm] } \end{document} This produces the following output: Issue When using the {...} notation to set the data of automatically generated entries, the data is not stored (see Automatic 5 Speed in MWE). The / notation seems to work. What was tried so far The problem seems to be related to the .is setter pgfkeys handler. It seems like the nested structure is not created, but a single key with e. g. product/manufacturer as id (with the / being interpreted as a letter, not a separator). So far, the following has been tried: Changing .code to .ecode Modifying the expansion from \noexpand to other possibilities Those experiments always resulted in errors and the compilation failing. Question Is there a simple way to achieve the desired behavior with pgfkeys (e.g. via .is family)? Suggestions of other methods are also welcome. However, solutions with pgfkeys would be preferred, since the rest of the data handling in the real project is already based upon pgfkeys.

I would have thought that if I declare \let\stdeqref\eqref, then the \stdeqref macro and the \eqref macro would be interchangeable. But here is an example where it fails! Moreover, this failure is (somehow) caused by the microtype package?! What is going on, and how to fix it? \documentclass{article} \usepackage{microtype} \usepackage{amsmath} \let\stdeqref\eqref \begin{document} \begin{equation}\label{a} A \end{equation} This is good spacing: \eqref{a}\allowbreak\eqref{a} This is bad spacing: \stdeqref{a}\allowbreak\stdeqref{a} But the bad spacing becomes good if we remove microtype! \end{document} The reason I'm asking is that I would like to redefine the \eqref macro in a way which uses the usual \eqref macro as a subcomponent, via the usual strategy I've seen time and time again on this site: \let\stdeqref\eqref \renewcommand\eqref[1]{Something fancy containing \stdeqref{#1} etc.} but that doesn't work anymore if \let isn't behaving as expected . . .

Thank you.

I'm using the enumext package to create multiple-choice questions. In my case, the answer labels are boxed letters, produced using the wrap-label key. The issue is that the boxed letters appear too close to each other vertically. I would like to know the correct way to increase the vertical spacing between the boxed labels, without unnecessarily changing the text spacing or breaking the column alignment. Here a MWE: \documentclass[a4paper,12pt]{article} \usepackage{amsmath, amssymb} \usepackage{graphicx} \usepackage{enumext} \begin{document} \begin{enumext}[label=\textbf{Domanda} \arabic*.,wrap-label=\textbf{#1},list-indent=0pt, save-ans=test] \item Lion \setenumext[keyans]{label=\Alph*,font=\small,nosep,wrap-label={\fbox{\makebox[\height]{##1}}}} \begin{keyans}[columns=2,nosep,mini-env={0.4\linewidth}] \item \item \item \item \miniright \includegraphics[scale=.4]{example-image.png} \end{keyans} \end{enumext} \end{document}

I'm using a template in Overleaf to make a mock article for practice, but it used natbib instead of biblatex so I attempted to replace the package and did all of the suitable replacements (like \citep to \parencite) But, it produced this "ugly" bibliography like below.

Is it possible to use circuitikz-shapes as cells inside a TikZ-matrix? (I mean, as cells <*> & <*> & <*> ... \\, how to place nodes afterwards is already clear.)

According to the manual, section 3.1.4.1 "Components size", bipoles/length (default 1.4cm) is the central parameter; "which can be interpreted as the length of a resistor (including reasonable connections): all other lengths are relative to this value."

In the listings package, \lstset{numbers=right,stepnumber=3,numberfirstline} gives right-aligned line numbers and numbering every third line.

I recently learned that it's possible to set fully custom page dimensions using geometry. However as far as I can tell, you can only do rectangular document shapes. Is it possible to use the geometry package or some other method to make the document itself circular?

The following code produces the output shown. It uses an enviroment inside which there is a description list with just one item. Note the blank line before \item. With that, or with instead, {} or \mbox{}, the code compiles as expected. However, removing that blank line before \item causes error "Something's wrong--perhaps a missing \item when compilation reaches the line \end{oneproperty}.

I'm typesetting my math document in Times New Roman using XeLaTeX and the fontspec package. I'm using mtpro2 as the math font, but I've noticed that certain letters, such as u, v and w, look quite different from their TNR italic counterparts (maybe because it's advertised as a Times-compatible font). Considering I'm already using the fontspec package, I tried ditching mtpro2 entirely and using other math fonts. I consulted the LaTeX Stack Exchange master list of maths fonts and tried XITS Math, TeX Gyre Termes Math and STIX Two Math. However, these fonts lack some features that I really like about mtpro2, such as round brackets (especially for matrices) and the letter z identical to the letter z in TNR. mtpro2 is here to stay. Next, I found the 'mathastext' package, which enables alphanumeric glyphs from the text font to be used in maths environments. For example, \usepackage[basic, italic]{mathastext} replaces all the alphanumeric characters in the maths font with the corresponding characters in the text font. However, this approach led me to another issue: the spacing between letters is awful, especially the subscripted ones. Since my only issue is with the letters u, v, and w, is there a way to just replace those three and use the rest of the mtpro2 glyphs? The code I'm using for my document is really bog standard: \documentclass{memoir} % Throw an error if this is not XeLaTeX. \usepackage{ifxetex} \RequireXeTeX \usepackage[lite]{mtpro2} \usepackage[no-math]{fontspec} \setmainfont{Times New Roman} \begin{document} \end{document} Any help would be appreciated.

I want to create an en amp with a pin length of 0 - alternatively: a pin length with a clearly defined value, for example 5mm.

The code is partially taken from egreg's this answer. I want to typeset the following three languages with three fonts: English: EB Garamond Chinese: FandolSong Greek: Old Standard Noted that I want to write an "English and Chinese" mixed article(which means that it need to switch frequently) to introduced the third language——Greek. As below: \documentclass{book} \usepackage{fontspec} \usepackage{polyglossia} \setmainlanguage{english} \setmainfont{EB Garamond}% English \newfontfamily{\chinesefont}{FandolSong}% Chinese \setotherlanguage{greek} \newfontfamily{\greekfont}{Old Standard}% Greek \begin{document} I want to typeset an article, whose main text is the combination of English, Chinese, which is used to introduced the Greek letters. I want three fonts for them. So, I want to use English and Chinese, switching frequently. And use Greek fonts in whole paragraph. \bigskip English: English Saṃskṛtāvāk Chinese: {\chinesefont 英语、中文 01234 这是一个测试} Greek: {\greekfont τὸν πόλεμον τῶν Ἀθηναῖος} It works well. However, what I want in the real case, is as follows: \bigskip An paragraph of English and Chinese, which shifts frequently. 我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。 {\chinesefont 我是英语} English {\chinesefont 和中文} Chinese {\chinesefont 混排。} is okay, but extremely difficult to switch... Then a paragraph of Greek letters. \textgreek{Θουκυδίδης Ἀθηναῖος ξυνέγραψε τὸν πόλεμον τῶν Πελοποννησίων καὶ Ἀθηναίων, ὡς ἐπολέμησαν πρὸς ἀλλήλους, ἀρξάμενος εὐθὺς καθισταμένου καὶ ἐλπίσας μέγαν τε ἔσεσθαι καὶ ἀξιολογώτατον τῶν προγεγενημένων, τεκμαιρόμενος ὅτι ἀκμάζοντές τε ᾖσαν ἐς αὐτὸν ἀμφότεροι παρασκευῇ τῇ πάσῃ καὶ τὸ ἄλλο Ἑλληνικὸν ὁρῶν ξυνιστάμενον πρὸς ἑκατέρους, τὸ μὲν εὐθύς, τὸ δὲ καὶ διανοούμενον.} It's hard for \texttt{polyglossia} to support an English font together another Chinese font. Is that any ideas? \end{document} I can't set Chinese and English fonts seperately, so frequently switch is quite difficult. I have also tried Fallback, but it doesn't work: \setmainfont[Fallback=FandolSong]{EB Garamond} If somebody get familiar with ctex-bundle, to set Chinese fonts and English fonts seperately, we could use: \usepackage{ctex} \setmainfont{EB Garamond} \setCJKmainfont{FandolSong} However, polyglossia is a little bit conflict with ctex(That maybe my another question or issues). So, this post, I was only after for a ployglossia(or babel) solution.

The content in some of my frames extends too far down, even when there is vertical space above that could be used. Here is an example. I would prefer for it to use the vertical space at the top before extending off the page. Is there a clean way to accomplish (at least part) this without doing a manual negative vspace? \documentclass{beamer} \useoutertheme{smoothbars} \begin{document} \section{Summation operator and the mean} \begin{frame} \begin{theorem} Is the following equality necessarily true? \[ \sum^{n}_{i=1}\left(ax_{i}+by_{i}\right)=a\sum^{n}_{i=1}x_{i}+b\sum^{n}_{i=1}y_{i} \] \end{theorem} % \begin{theorem} Yes, it is true. But what's the intuition for it? \end{theorem} \begin{itemize} \item Whenever you're stuck proving a general statement, it's often useful to try a special case. For example, what if $n$ equals 2? \begin{block}{} Then the question reduces to the following: \begin{align} \left(ax_{1}+by_{1}\right)+\left(ax_{2}+by_{2}\right) & \,\,\,=\,\,\,a(x_{1}+x_{2})+b(y_{1}+y_{2})\\ & \Longleftrightarrow\\ \left(ax_{1}+ax_{2}\right)+\left(by_{1}+by_{2}\right) & \,\,\,=\,\,\,a(x_{1}+x_{2})+b(y_{1}+y_{2}) \end{align} \end{block} \item We're summing the same numbers, just in a different order! \end{itemize} \end{frame} \end{document} Here is the result that I get: I understand there is no so much vertical space at the top, but I would still rather have the "Theorem" text start just after the mini frames, rather than content go off the page. Maybe what I'm asking for is "vfill" behavior, where it stretches or squeezes depending on the situation?

I searched for something similar, but I didn't find anything. \documentclass{report} \usepackage{amsmath} \usepackage{mathtools} \DeclareMathOperator{\diff}{d} \begin{document} \[\int x\diff x\] \end{document} I want to get "dx" and not "d x". I was looking at ways to eat spaces after the command, but nothing, I would like to avoid adding the "x" as a parameter to the \diff operator. I would like you know if there is a way.

Unfortunately, all keys are broken except for one row: \verb$1$, \verb$2$, \verb$3$, \verb$+$ and \verb$-$. Tom presses a sequence of $n$ random keystrokes; at each stroke, each key is equally likely to be pressed. The calculator then evaluates the entire expression, yielding a result of $E$. Find the expected value of $E$, in terms of $n$. (Negative numbers are permitted, so \verb$13-22$ gives $E = -9$. Any excess operators are parsed as signs, so \verb$-2-+3$ gives $E=-5$ and \verb$-+-31$ gives $E = 31$. Trailing operators are discarded, so \verb$2++-+$ gives $E=2$. A string consisting only of operators, such as \verb$-++-+$, gives $E=0.) \end{problem} for the problem, but the last line has the following error message: LaTeX Error: Command \end{mdframed} invalid in math mode. \ (button saying suggest fix using AI) \ Missing $ inserted. \ Missing } inserted. \ Extra }, or forgotten \endgroup.

I need to use \ProcessList and \SplitArgument with \IfBoolean. Using only \ProcessList does work, but I need to get at the arguments before and after the / -- thus the need for \SplitArgument. The asterisk seems inextricably attached to the second argument in \fooauxai and I cannot seem to pry it loose. As indicated, I've tried some \expandafter experiments. Suggestions? \documentclass{article} \usepackage[papersize={5.5in,8.5in},margin=0.6in]{geometry} \usepackage{xparse}%% for <u> %% |=====8><-----| %% %% This works \NewDocumentCommand{\test}{ >{\SplitList{;}}m }{\ProcessList{#1}{\fooaux}} \NewDocumentCommand{\fooaux}{ m }{\fooauxa#1|} \NewDocumentCommand{\fooauxa}{ s u{|} }{% \def not possible due to need for boolean \IfBooleanTF{#1}{\textcolor{red}{#2}}{#2} } %% |=====8><-----| %% %% This does not work \NewDocumentCommand{\testi}{>{ \SplitList{;}}m } {\ProcessList{#1}{\fooauxi}} %% Tried this but to no avail: %% \NewDocumentCommand{\fooauxi}{ >{\SplitArgument{1}{/}}m } {\expandafter\fooauxai#1|} \NewDocumentCommand{\fooauxi}{ >{\SplitArgument{1}{/}}m } {\fooauxai#1} \NewDocumentCommand{\fooauxai}{ s m m }{% \IfBooleanTF{#1}{\textcolor{red}{(#2)}}{(#2)}-(#3) } %% |=====8><-----| %% \begin{document} \thispagestyle{empty} \begin{tabular}{lll} 1& From \verb+\test+& \test{a/1;*b/2;c/3}\\ 2& From \verb+\testi+& \testi{a/1;*b/2;c/3}\\ 3& Desired& (a)-(1) \textcolor{red}{(b)}-(2) (c)-(3) \end{tabular} \end{document}

In an expl3 package a Lua module shall be used because Lua simplifies programming some functions. The Lua module shall call some expl3 functions from the package. But this does not work in all cases. In the following example only \MyDocumentCommandA works, not \MyDocumendCommandB. \begin{filecontents*}{mypackage.sty} \ProvidesExplPackage{mypackage}{2025-12-27}{1.0}{My package} \directlua { myluamodule = require ('myluamodule') } \cs_new:Npn \mypackage_command:n #1 { \int_to_Roman:n {#1} } \NewDocumentCommand \MyDocumentCommandA {m} { \directlua { myluamodule.functionA ( #1 ) } } \NewDocumentCommand \MyDocumentCommandB {m} { \directlua { myluamodule.functionB ( #1 ) } } \end{filecontents*} \begin{filecontents*}{myluamodule.lua} local myluamodule = {} myluamodule.functionA = function (nr) tex.sprint("bla blub ") tex.sprint("\\ExplSyntaxOn") tex.sprint("\\mypackage_command:n{"..nr.."}") tex.sprint("\\ExplSyntaxOff") end myluamodule.functionB = function (nr) tex.sprint("\\section{") myluamodule.functionA(nr) tex.sprint("}") end return myluamodule \end{filecontents*} \documentclass{article} \usepackage{mypackage} \begin{document} \MyDocumentCommandA{75} \MyDocumentCommandB{85} \end{document} The error message is: ! Undefined control sequence. <argument> bla blub \ExplSyntaxOn \mypackage _command:n{85}\ExplSyntaxOff l.43 \MyDocumentCommandB{85}
