I'm trying to typeset a project using TeX Gyre Pagella (Math). When I try to produce the limit of a function (see MWE), the space between the "lim" and "f" is far too small. Is there a way to increase this space (for all instances of the limit) outside of manually using \, or other spacing commands? For transparency, I'm using XeLaTeX on Overleaf. I don't know whether a local instance of XeLaTeX will produce the same result. \documentclass{minimal} % \usepackage{amsmath} \usepackage{unicode-math} \setmainfont{TeX Gyre Pagella} \setmathfont{TeX Gyre Pagella Math} \begin{document} We say that \begin{equation*} \lim_{x \to a} f(x) = L \end{equation*} if, insert $\varepsilon$ and $\delta$ definition here. \end{document} Similar results are produced using TeX Gyre Termes (see images). Interestingly, newpx (which apparently loads Pagella) does not have this problem. (But I have other opinions about it which are not within the scope of the question anymore.)

I would like to compile the following simple example of a LaTeX document with the tool arara, taken from its quickstart guide: % arara: pdflatex \documentclass{article} \begin{document} Hello world! \end{document} Let us refer to this file as main.tex and locate it in the directory project/src. When I now call arara from directory project/src, everything works as expected: >> arara main.tex __ _ _ __ __ _ _ __ __ _ / _` | '__/ _` | '__/ _` | | (_| | | | (_| | | | (_| | \__,_|_| \__,_|_| \__,_| Processing "main.tex" (size: 94 B, last modified: 2026-10-22 14:02:02), please wait. (PDFLaTeX) PDFLaTeX engine .............................. SUCCESS Total: 0.254 seconds All output (and auxiliary) files are created properly and saved to the directory project/src. Now, suppose there is another directory project/out. I want pdflatex to put all the output (and auxiliary) files into this directory. Thus, I need to use the -output-directory flag. Moreover, I want to call arara from directory project. I simply changed line 1 of main.tex into % arara: pdflatex: { options: [ '-output-directory=./out/' ] } Running arara from project (with corrected path to main.tex), pdflatex cannot find the main.tex file: >> arara src/main.tex --verbose __ _ _ __ __ _ _ __ __ _ / _` | '__/ _` | '__/ _` | | (_| | | | (_| | | | (_| | \__,_|_| \__,_|_| \__,_| Processing "main.tex" (size: 139 B, last modified: 2026-10-22 14:02:16), please wait. ----------------------------------------------------------------- (PDFLaTeX) PDFLaTeX engine ----------------------------------------------------------------- This is pdfTeX, Version 3.141592653-2.6-1.40.29 (TeX Live 2026) (preloaded format=pdflatex) restricted \write18 enabled. entering extended mode !

Both solutions are not appropriate for my setting. How can I call arara from project, having main.tex in project/src? I use arara in version 7.2.0 and pdflatex in version 3.141592653-2.6-1.40.29.

Consider the code: \documentclass[12pt,onecolumn,openany,final]{book} \usepackage[hmargin=0in,vmargin=0in,top=0in,paperwidth=4.25in,paperheight=6.625in]{geometry} \usepackage{pstricks,psvectorian} \usepackage{scalerel,scalefnt} \usepackage{color,cabin} \definecolor{RomeRed}{RGB}{142,0,28} \definecolor{RomeYellow}{RGB}{255,179,0} \setmainfont{Cabin} % Interletterspacing Letters \def\theLetterSpace{0.5pt} \def\theWordSpace{1.5\LocalLetterSpace} \newlength\LocalLetterSpace \newcommand\spaceout[2][\theLetterSpace]{% \setlength\LocalLetterSpace{#1}\expandafter\spaceouthelpA#2 \relax\relax} \def\spaceouthelpA#1 #2\relax{% \spaceouthelpB#1\relax\relax% \ifx\relax#2\else\ \kern\theWordSpace\spaceouthelpA#2\relax\fi } \def\spaceouthelpB#1#2\relax{% #1% \ifx\relax#2\else \kern\LocalLetterSpace\spaceouthelpB#2\relax% \fi } \begin{document} \thispagestyle{empty} \pagecolor{RomeRed} \noindent\begin{pspicture}(-5.3975,0)(5.3975,16.8275)% \renewcommand*{\psvectorianDefaultColor}{RomeRed}% \psframe[fillcolor=RomeRed,fillstyle=solid](-5.3975,0.3175)(5.08,16.51)% \psframe[linecolor=RomeRed](-5.3975,0.3175)(5.08,16.51)% draws frame. \rput[tc](0.07,14.00){\textcolor{white}{\Huge{\selectfont\scalefont{1.11} \vstretch{1.35}{\textbf{{\spaceout[3.25pt]{COLOR {\it(CHANGE)}}}}}}}} \end{pspicture}% \end{document} which gives the output: I would like to change the color of (CHANGE) from white to RomeYellow, but I have not been able to do it. I think it should be easy but I do have some other stuff going on which may be causing the difficulty. I have used \textcolor{RomeYellow}, \color{RomeYellow}, and \color{RomeYellow} alternately in different locations but to no avail. QUESTION: How may I color the italicized portion of the title to the color RomeYellow? I am compiling with xelatex.

I am using the siunitx package and want to format a measurement with its uncertainty, for example: 31.76 ± 0.34 g I have tried the following: \SI{31.76(34)}{\gram} However, this produces (31.76 ± 0.34) g, with the uncertainty enclosed in parentheses. I have also tried: \SI{31.76 +- 0.34}{\gram} but this produces (31.76 ± 0.34) g, with the entire expression enclosed in parentheses. How can I use siunitx to produce 31.76 ± 0.34 g without parentheses around either the uncertainty or the entire expression? I would prefer a solution that uses siunitx commands rather than manually formatting the units.

My example below: \documentclass{article} \usepackage{multicol} \begin{document} \begingroup \parindent=0pt \interlinepenalty=10000 \begin{multicols}{2} A\\ B\\ C \par \rule{.7\linewidth}{.6pt}\\ D\\ E\vskip23pt F \end{multicols} \endgroup \end{document} results in the following: But if I change \vskip23pt to \vskip24pt, then the column break will shift position, and the result will be: I did all this just to show that \interlinepenalty=10000 is working correctly—that is, there is no page break between the \rule and the letter “D”. The problem arises when the code becomes a bit more complicated: \documentclass{article} \usepackage{multicol} \begin{document} \def\x#1{\par{\centering \rule{.7\linewidth}{.6pt}\\ #1\par}} \begingroup \parindent=0pt \interlinepenalty=10000 \begin{multicols}{2} \x{A\\ B\\ C} \x{D} \x{E} \x{F} \end{multicols} \endgroup \end{document} Which generates: My question is: why did a column break occur between \rule and the letter “D” in this case?

I came across an inconsistent vertical spacing if a tblr with long option directly follows a section. If due to other generic content there is a pagebreak before the section, the vertical spacing between tblr and the section title can get screwed up. Weirdly, this is only true for a rather specific value for the vspace in the MWE. If it's at 15 cm, everything fits nicely on one page and the spacing is correct. If it's set to 18 cm or more, again the spacing on the next page is correct. Is this a bug I should report, or is this solvable? \documentclass[a4paper,11pt]{article} \usepackage{tabularray} \begin{document} \section*{Some Section} \begin{tblr}[long,label=none,presep=0mm,headsep=0pt,footsep=0pt]{width=\linewidth,colspec={l|X},stretch=0,rowhead=0,rowfoot=0} {Bla} & {Blub}\\ \end{tblr} \section*{Another Section} \begin{tblr}[long,label=none,presep=0mm,headsep=0pt,footsep=0pt]{width=\linewidth,colspec={l|X},stretch=0,rowhead=0,rowfoot=0} {Bla} & {Blub}\\ \end{tblr} \vspace{16cm} %try 15cm (fits on same page without issue) and 18cm (next page, no issue) \section*{Yet Another Section} \begin{tblr}[long,label=none,presep=0mm,headsep=0pt,footsep=0pt]{width=\linewidth,colspec={l|X},stretch=0,rowhead=0,rowfoot=0} {Bla} & {Blub}\\ \end{tblr} \end{document}

The following file (which comes from an article in the TeXnische Komödie about the schulma-physik package), say subfile.tex, compiles like a charm: \documentclass{article} \usepackage[compatibility]{circuitikz} \usetikzlibrary{circuits.ee.IEC} \makeatletter % Ergänzungen von Schaltzeichenformen auf der Grundlage von pgflibraryshapes.gates.ee.IEC.code.tex \pgfdeclareshape{leere diode} {% \inheritsavedanchors[from=rectangle ee]% \inheritanchor[from=rectangle ee]{center}% \inheritanchor[from=rectangle ee]{north}% \inheritanchor[from=rectangle ee]{south}% \inheritanchor[from=rectangle ee]{east}% \inheritanchor[from=rectangle ee]{west}% \inheritanchor[from=rectangle ee]{north east}% \inheritanchor[from=rectangle ee]{north west}% \inheritanchor[from=rectangle ee]{south east}% \inheritanchor[from=rectangle ee]{south west}% \inheritanchor[from=rectangle ee]{input}% \inheritanchor[from=rectangle ee]{output}% \inheritanchorborder[from=rectangle ee]% % \backgroundpath{ \pgf@process{\pgfpointadd{\southwest}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}} \pgf@xa=\pgf@x \pgf@ya=\pgf@y \pgf@process{\pgfpointadd{\northeast}{\pgfpointscale{-1}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}}} \pgf@xb=\pgf@x \pgf@yb=\pgf@y % Move tip back a little bit \advance\pgf@xb by-.5\pgflinewidth % Triangle triangle: \pgfpathmoveto{\pgfqpoint{\pgf@xa}{\pgf@ya}} \pgfpathlineto{\pgfqpoint{\pgf@xa}{\pgf@yb}} \pgf@yc=.5\pgf@ya \advance\pgf@yc by .5\pgf@yb \pgfpathlineto{\pgfqpoint{\pgf@xb}{\pgf@yc}} \pgfpathclose }% \beforebackgroundpath{ { \pgf@process{\pgfpointadd{\southwest}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}} \pgf@ya=\pgf@y \pgf@process{\pgfpointadd{\northeast}{\pgfpointscale{-1}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}}} \pgf@xb=\pgf@x \pgf@yb=\pgf@y \pgf@yc=.5\pgf@ya \advance\pgf@yc by.5\pgf@yb \pgfusepathqstroke \pgftransformshift{\pgfqpoint{\pgf@xb}{\pgf@yc}} \pgf@yc=.5\pgf@yb \advance\pgf@yc by-.5\pgf@ya \pgftransformscale{\pgf@sys@tonumber{\pgf@yc}} \pgfkeysvalueof{/pgf/generic diode IEC/before background} } }% } \makeatother \tikzset{ leere diode graphic/.style={ circuit symbol open, circuit symbol size=width 1.25 height 1.25, transform shape, shape=leere diode, /pgf/generic diode IEC/before background={ \pgfpathmoveto{\pgfqpoint{0pt}{-1pt}} \pgfpathlineto{\pgfqpoint{0pt}{1pt}} \pgfusepathqstroke }, }, } \begin{document} \begin{tikzpicture}[circuit ee IEC,circuit symbol unit=5.5pt] \tikzset{set diode graphic=leere diode graphic}\draw (0,0) to[diode] (1,0); \end{tikzpicture} \end{document} But if it is compiled via another file—say, mainfile.tex—using the standalone package: \documentclass[french]{article} \usepackage[subpreambles]{standalone} \begin{document} \input{subfile.tex} \end{document} the second compilation fails with the following error: (./subfile.tex !

Although the mainfile.sta file contains the entire preamble of the subfile.tex file—including the \makeatletter and \makeatother commands—it appears that the @ character is not treated as a letter. Do you understand why, and do you know how to solve this problem?

This is a follow up to my question. The accepted answer has enabled me to resolve that question. When I implement that answer, a further issue arises. If I add a second part to the test document, the toc entry for the previous part is added to the toc for the last chapter of the previous part. The answer code (without dummy text) produces the header pages: These are all as required, and expected. If I add a second part to the document: \documentclass{memoir} \usepackage{lipsum} \makeatletter \newcounter{tocmarker} \newcounter{ptocmarker} \renewcommand\mempreaddchaptertotochook{\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand\mempreaddparttotochook {\cftinserthook{toc}{pstop-\theptocmarker}} \renewcommand{\mempostaddchaptertotochook}{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth \newcommand\chaptertoc{% \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}}% \let\changetocdepth\@gobble \normalchangetocdepth{-10}% \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{2}}% \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}}% \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}}% \par\bigskip \@afterheading } % %******************************* \renewcommand\mempostaddparttotochook{% \stepcounter{ptocmarker}\cftinserthook{toc}{pstart-\theptocmarker}} \let\normalchangetocdepth\changetocdepth % for later \newcommand\parttoc{% \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}}% \let\changetocdepth\@gobble \normalchangetocdepth{-10}% \cftinsertcode{pstart-\theptocmarker}{\normalchangetocdepth{1}}% \cftinsertcode{pstop-\theptocmarker}{\normalchangetocdepth{-10}}% \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}}% \par\bigskip \@afterheading } % manual p81 \renewcommand*{\beforepartskip}{\null\vskip4cm} \renewcommand*{\afterpartskip}{\par\vskip1cm% \@afterindentfalse\@afterheading \parttoc } \makeatother %******************************* \begin{document} \tableofcontents* \part{Rewrite v2} \chapter{Chapter} \chaptertoc \section{Section} \part{Rewrite v2 Part II the exorcism} \chapter{Chapter2 of II} \chaptertoc \section{Section} \end{document} This header pages produced are shown below.

I want to add a post-scriptum to a letter so I wrote this : \documentclass[12pt]{lettre}% \usepackage[utf8]{inputenc} \usepackage{french} \usepackage[OT1]{fontenc} \usepackage{mltex} \institut{identite} \begin{document} \begin{letter}{address} \conc{FCT PhD Studentships} \opening{Dear professor,} Body \closing{Yours sincerely,} \ps P.S.

I am trying to create a bibliography which contains references between certain entries. E.g., in entry [2] I would like to have a text saying "conference version of [1]" (where [1] refers to another entry of the same bibliography. One way of achieving that seems to be to add something like note = {conference version of \cite{JournalVersion}} I am, however, looking for a cleaner/more structured way of achieving this. It seems to me that the field related should be the solution here -- and it does work, if I want to reference the other entry by, e.g., title. However, I have not been able to get it to work using the reference itself. My current MWE is !BIB program = biber \documentclass{article} \usepackage{biblatex} \begin{filecontents}{literature.bib} @article{JournalVersion, author = {Graf, Lukas}, title = {Title A}, journal = {Journal}, year = {2020}, } @InProceedings{ConferenceVersion, author={Graf, Lukas}, title={Title B}, booktitle={Conference Proceedings}, year={2019}, related = {JournalVersion}, relatedtype = {conferenceof} } @InProceedings{ConferenceVersionVar, author={Graf, Lukas}, title={Title C}, booktitle={Conference Proceedings}, year={2019}, note = {conference version of \cite{JournalVersion}} } \end{filecontents} \addbibresource{literature.bib} \newbibmacro*{related:conferenceof}[1]{conference version of % \entrydata*{#1}{% \usebibmacro{title} \printtext[labelnumberwidth]{\printfield{labelnumber}}% }% } \begin{document} \nocite{*} \printbibliography \end{document} Using biber and pdflatex, this produces the following output: Here, entry [3] shows how the desired output looks like (but it is achieved using the note-field), entry [2] is the one where I tried (and failed) to implement an approach using the related-field. I additional reference [1] here by title, to test whether the related-field itself works.

I am using the book class. My main file includes the following toc styling commands: \documentclass{book} \usepackage{nonumonpart} \usepackage{tocloft} \usepackage{calc} \usepackage[titletoc,title]{appendix} \renewcommand{\cftpartfont}{\LARGE\bfseries} \renewcommand{\cftchapfont}{\large\bfseries} \setlength{\cftchapnumwidth}{1.1875in}\renewcommand{\cftchappresnum}{Chapter }\renewcommand{\cftchapaftersnum}{:\phantom{mm}}\cftpagenumbersoff{part}\renewcommand\cftchapafterpnum{\par\addvspace{6pt}} \setlength{\cftbeforepartskip}{17pt} Borrowing from Werner's answer [here][1]. I included the following code to change the ToC's printing from "Chapter" to "Appendix": \let\oldappendix\appendix \renewcommand{\appendix}{% \oldappendix \addtocontents{toc} % Update \cftchappresnum within the .toc {\protect\renewcommand{\protect\cftchappresnum}{\appendixname\space}} } \renewcommand{\contentsname}{\underline{Table of Contents}}\setlength\cftbeforetoctitleskip{24pt}\setlength\cftaftertoctitleskip{24pt} \begin{document} ... \include{ch12} \appendix \pagenumbering{arabic} \renewcommand\thepage{A\arabic{page}} \include{appendixA} \pagenumbering{arabic} \renewcommand\thepage{B\arabic{page}} \include{appendixB} \end{document} It changes for Appendix B but not Appendix A: [![answer][2]][2] Does anyone know why it's not overriding the "Chapter" for Appendix A, and/or how to change that? EDIT: After using \begin{appendices} \addtocontents{toc}{\def\protect\cftchappresnum{\appendixname{} }} \pagenumbering{arabic} \renewcommand\thepage{A\arabic{page}} \include{appendixA} \pagenumbering{arabic} \renewcommand\thepage{B\arabic{page}} \include{appendixB} \end{appendices} it now prints: Appendix Chapter A: Appendix Appendix B: so now I just need to suppress the second word each time.

I’ve found that the secret behind BaKoMa’s incremental compilation seems to be hidden in itex.dll, which is located in the BaKoMa installation directory. There’s a reverse-engineering repository available at https://github.com/morluto/rea. Has anyone tried using Claude or ChatGPT to help implement incremental compilation?

I am looking for a way to highlight the end of a mathematical calculation. Not to say it's important, like \boxed does, but merely to clarify what one has ended with. See the red in the following image: So it can be translated to the following (considering \asresult{} draws the red line as above): \documentclass{article} \usepackage{amsmath, tikz} \newcommand{\diff}{\mathrm{d}} % differential pebble \newcommand{\asresult}[1]{ % result highlight %... } \begin{document} The derivation of the derivate of the exponential, under such new tools, needs a re-route first: \begin{align*} e^{\diff x} &= \sum_{k=0}^\infty \frac{\diff x^k}{k!} \\ &= \asresult{1 + \diff x} \\ (\diff e^x)(t) &= \lim_{h \to 0} e^{x(t+h)} - e^{x(t)} \\ &= e^{x(t)} \lim_{h \to 0} e^{x(t+h) - x(t)} - 1 \\ &= e^{x(t)} (e^{\diff x(t)} - 1) &= \asresult{e^{x(t)} \diff x(t)} \end{align*} And with that, one deduces $\cfrac{\diff e^x}{\diff x} = e^x$, QED. \end{document} How can I add this \asresult?

How can I link a part toc into the part header page? I am trying to implement part specific and chapter specific toc on their relative title headers. The code for the chapter toc is based directly on pp 414-417 of memman.pdf and works well. I (naively) thought that repeating the code but replacing chapter with part would result in a corresponding part toc. My implementation of this does not seem to hook the part and the toc together. The attached code shows the wanted main toc, and chapter specific toc; but does not show the part toc. I expected a toc very similar to that for chapter on the title page. My example below shows the code for the chapter and the part toc. The part toc portion has been bounded by &**********. I have removed a lot of code concerning toc formatting, so the formats may be off. To aid me I have used: memoir: Chapter TOCs (Part 1) memoir: Chapter TOCs (Part 2) memoir: Chapter TOCs (Part 3) These have been very helpful, but when they venture into Tex code, rewriting parts of memoir, and @ symbols and the like, they are way above my competence. \documentclass{memoir} \usepackage{lipsum} \makeatletter \newcounter{tocmarker} \renewcommand\mempreaddchaptertotochook{\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand\mempreaddparttotochook {\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand{\mempostaddchaptertotochook}{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth \newcommand\chaptertoc{ \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}} \let\changetocdepth\@gobble \normalchangetocdepth{-10} \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{2}} \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}} \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}} \par\bigskip \@afterheading } %******************************* \renewcommand\mempostaddparttotochook{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth % for later \newcommand\parttoc{ \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}} \let\changetocdepth\@gobble \normalchangetocdepth{-10} \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{1}} \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}} \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}}% \par\bigskip \@afterheading } \makeatother %******************************* \begin{document} \tableofcontents* \part{Rewrite v2} \parttoc \chapter{Chapter} \chaptertoc \section{Section} \lipsum \end{document}

For certain reasons I have to use TeXShop version 3.62 in a project. It works fine with Sequoia 15.7.7, but will it work if I upgrade to Tahoe? Sorry, I guess I asked the wrong question. The TeXShop version does not seem to be important in this project. The relevant question should probably be "Will TeXLive 2016 work with MacOS Tahoe?" Obviously, I run into problems when I try TeXLive 2025 on Sequoia. So, why is this a problem? It works fine for me as it is, but I have a collaborator who does not have administrator rights on his computer. He has to use the OS that his employer has chosen, in this case Tahoe.

Good evening everyone, I am facing a problem when I designate crystallographic faces with the Miller notation (via the miller package).

Here is a MWE where the caption of a longtable is being tagged as a table row (TR) and as a header row (TH) using lualatex (and lualatex-dev) with tagging=on. This leads to Regularity errors in the Adobe Acrobat checker. [I'm running the latest MikTeX updates with latex-tools updated as well.] Am I doing something incorrectly, or is there a longtable conflict with the tagging tools?

Looking over many examples of LaTeX code in macro definitions, I often find a % at the end of a line --- so that no extraneous spaces are somehow imported into the macro by the end of line character. However, at the same time, I notice that these same macros often have many lines starting wit indentations --- presumably to make the code readable. How come the code can be indented at all? Why should every line in the macro have any opening spaces at all? Isn't the point of % to avoid extraneous spaces? Why do we care about that at the end of the line, but do not care about it at the beginning of the line?

I have updated MikTex, and now I get this error when I compile my tex files with pdflatex: ! Use of \??? doesn't match its definition. <argument> \??? ! Latex Error: Misplaced '=' in key-value input on line 59. The pdf file produced looks good, it has the hyperlinks that I expect. When I comment out the hyperref package, no error is thrown, but then of course, the expected hyperlinks the hyperref package produces are not there. I have found a post referring to a similar issue, where a re-installation has solved the problem. However, this did not work for me.

This post is similar to this one, but not exactly the same...

I am using the luacas package to handle symbolic math and compute coordinates. Currently, to display the vector $\vec{AB}$ from two points $A$ and $B$, I have to subtract and print each component individually like this: \documentclass[12pt]{article} \usepackage{amsthm} \theoremstyle{definition} \newtheorem{ex}{Example} \usepackage{luacas} \usepackage{esvect} \begin{document} \begin{ex} \begin{CAS} A = {sqrt(2), -2/7, 3/5} B = {sqrt(8), -14/29, 3*sqrt(3)} \end{CAS} \[\displaystyle A=\left(\print{A[1]};\print{A[2]};\print{A[3]} \right), \quad B=\left(\print{B[1]};\print{B[2]};\print{B[3]} \right).\] \[ \vv{AB}=\left(\print{simplify(B[1]-A[1])};\print{B[2]-A[2]};\print{B[3]-A[3]} \right) .\] \end{ex} \end{document} This approach makes the code repetitive and messy. I would like to simplify the workflow by computing the vector directly within the CAS environment and printing it in one go, like this: \begin{CAS} A = {sqrt(2), -2/7, 3/5} B = {sqrt(8), -14/29, 3*sqrt(3)} vAB = B - A \end{CAS} \[\vv{AB} = \print{vAB}\] However, doing this directly does not work as expected. I got the massage: [string "A = {sqrt(Integer('2')), -Integer('2')/Intege..."]:1: attempt to perform arithmet ic on a table value (global 'B') stack traceback: [string "A = {sqrt(Integer('2')), -Integer('2')/Intege..."]:1: in local 'exe' ...26/texmf-dist/tex/lualatex/luacas/test/luacas-parser.lua:329: in function ' CASparse' [\directlua]:1: in main chunk. \luacode@dbg@exec ...code@maybe@printdbg {#1} #1 } l.15 \end {CAS} ? Is there a way to define a custom function, a macro, or use a specific luacas command/method so that I can compute $vAB = B - A$ (or simplify it) and print it cleanly without accessing each index manually?

I have defined a custom command for my images, which have different sizes and aspect ratios. \documentclass[a4paper,12pt]{scrreprt} % writing things \usepackage[T1]{fontenc} \usepackage{inputenc} \usepackage[ngerman]{babel} \usepackage{paralist} % document class things \usepackage[headsepline=1pt,autooneside=false]{scrlayer-scrpage} \usepackage{scrhack} % images \usepackage{graphicx} \usepackage[figurename=Abb.,tablename=Tab.]{caption} \usepackage{float} \usepackage{here} \usepackage[section]{placeins} % rest \usepackage{lipsum} \usepackage{hyperref} \usepackage[all]{hypcap} % commands \newcommand{\n}{\newline} \newcommand{\bild}[4][width=\textwidth]{ \begin{figure}[!hbt]\centering \makebox[\textwidth][c]{ \includegraphics[#1]{#2} } \caption{#3}\label{#4} \end{figure} } \clearmainofpairofpagestyles \cfoot[\pagemark]{\pagemark} \ohead{\scshape\rightmark} \automark{chapter} \renewcommand{\chaptermark}[1]{\markright{\ #1}} \begin{document} \thispagestyle{empty} \pagenumbering{Roman} \tableofcontents \listoffigures \pagestyle{scrheadings} \cleardoubleoddpage \pagenumbering{arabic} \chapter{first}\label{first} Lipsum.\n So so so... \chapter{one} \section{one} \lipsum\ref{b0} \bild{picture-15x21}{Picture.

Always keep the aspect ratio. EDIT: Actually, I'd like to have "0.5 * (\textheigt - height of the two captions)" instead of 0.45\textheight so that two graphics fill one page. But I think this is either too complex to write, too fault-prone to use or not realisable.

None of the 3 approaches I tried seems to work.
