I'm trying to use pgfmath to help with randomizing exam questions that I give my students. One of the hurdles I've come across is printing fractions correctly. I've defined the following command: \newcommand{\printFrac}[2]{ \pgfmathprintnumber[frac, frac whole=false, frac shift=1, precision=8]{\fpeval{#1/#2}} } While debugging, I've found that this fails with fractions like "10/41" and "16/9": \[10/41: \printFrac{10}{41}\qquad 16/9: \printFrac{16}{9}\] I read about and tried the pgfmath-xfp package, but the error still persists: \pgfmxfpdeclarefunction{myfrac}{2}{#1/#2} \newcommand{\printFrac}[2]{ \pgfmathparse{myfrac(#1,#2)} \pgfmathprintnumber[frac, frac whole=false, frac shift=1, precision=8]{\pgfmathresult} } Is there something obvious I'm missing? Should I be using another method to print out randomly generated fractions?

I'm trying to recreate this image on 5mm grid paper using the original dimensions. It's not a big problem; I'm just looking for some fine-tunings inside the circuitikz-package. I've tested a few keys, but I'm wondering: What is the correct method: to add a longer voltage arrow that's a bit further away from the source? to add a current arrow at the shown position in a package-like way (regular TikZ is clear)? PS: I would also like to reduce the (global setting!) size of the arrowheads and the control points ("poles", I haven't quite understood chapter 6.1 yet); but that might be too much for one thread. MWE: [I've only set a small excerpt here to address the problems. I can easily add the rest later by myself.] \documentclass[margin=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[font=\footnotesize\sffamily, european resistors, circuitikz/resistors/width=0.425,% default 0.8 circuitikz/bipoles/generic/height=0.165,% default 0.3 circuitikz/bipoles/thickness=1.0, % default 2 circuitikz/bipoles/vsource/width=0.35, circuitikz/bipoles/vsource/height=0.35, %circuitikz/bipole/is voltage=false, %circuitikz/voltage/distance from node=5.0875,% old: 0.8 %circuitikz/voltage shift sources adjust=4.525,% default: 0.5 %voltage shift=0.125,% optional ] \draw[gray!25, step=5mm] (-1.5,0.5) grid (4,-4); \draw[] (0,-2) to[vsource, v<=12V, mirror] (0,0) -- (1.5,0); \draw[] (0.5,0) to[R=15, *-*] (0.5,-1) to[R, a=25, -*] (0.5,-2); \end{circuitikz} \end{document}

I'm trying to customise the TOC using built in commands to allow for tagging support, but I'm running in to some behaviour I can't figure out. In the following MWE, the I set \contentsline@text@2@format to \emph and the the line is formatted as expected. But if I set it to \MakeUppercase the label structure breaks (in this case notice the missing space after the subsection number). Am I doing this wrong? I'm struggling to trace the code through to find out why this happens. %!

A few day ago I asked the following question: chemnum: How to create an alias compound label so two IDs print the same number (without breaking numbering)? Previous question: I am using chemnum and referencing compounds via \cmpd{...}. What I want is a simple alias mechanism: \cmpd{A} should define/print compound 1 after \makecmpdalias{A}{B}, \cmpd{B} should also print 1 (B is an alias for A) importantly, the next new compound should continue numbering normally, so \cmpd{C} should print 2 (not 3) similarly D and E should share one number.

I have been trying to coerce Claude to help me, but it is hilariously bad. I am trying to create a new character that looks like d <space> p, where the <space> becomes a connector. The font is charter, math, which I can pull off from newtxmath or mathdesign, which means the input is modestly slanted. \documentclass[12pt]{standalone} \usepackage{XCharter} \usepackage[charter,vvarbb]{newtxmath} \usepackage{amsmath} \begin{document} \fontsize{200}{172}\selectfont \ensuremath{d \kern22pt p} \end{document} I have blown this up here, but I shall need it in my normal font lateron. The result is supposed to look somewhat like: Obviously, one can do quite a bit better than me and my pen, especially, but not only at the lower left corner of my new connector. I will use this, in standard font size, a few hundred times in my document. Is it easy to create such a character? What program should I use? A low learning curve is a lot more important than versatility for further designs in the future. Once I have the character, how do I best use it in my document? Should I try to create its own one-character font, or just create a few PNG files at the right sizes that a \dp\ macro then inserts?

This might be a bit of a far-fetched question but I was wondering about programming a method of handling one of the last steps of completing a document where I currently scan each page and insert an \adaptlayout[lines=...] to handle irregular looking paragraph breaks. For example, one instance has a three-line paragraph near the end of a page, that leaves two blank lines at the bottom and pushes the paragraph to the next page. So, I either leave it, lengthen the page by one line, or shorten the previous page by one line. Regardless of how one chooses to handle such instances, is there a place to write such logic that could compare the difference in the number of blank lines at the end of facing pages and make such an adjustment, such that if the document was later modifed due to an overlooked typo or font change, one wouldn't have to redo that step? Is it even possible to execute code after the document has reached this point of completion? It might be a ridiculous thought because, following each insertion of an \adaptlayout[lines=...], the document would require a new run since every page thereafter until a section starts on new page would change and need re-evaluated. Thank you.

My university's thesis formatting guidelines are extremely stringent about margins, which means when a footnote gets split across pages (because the \footnotemark is on the bottom line of the page, so including the entire footnote would push the mark onto the next page), there's not much I can do to fix it. I can't, for example, expand the text box slightly, or insert some additional whitespace at the bottom. Proofreaders have found this confusing. So with the better typographical solutions being off-limits, I would like to at least indicate to the reader that the footnote continues on the next page. Is it possible to indicate some sort of symbol, such as a rightward-pointing arrow, at the point where a footnote has been split across pages, to indicate that it's continued elsewhere? I know some periodicals do this when an article is split across pages. MWE adapted from here: \documentclass[oneside]{book} \usepackage{lipsum} \usepackage[splitrule]{footmisc} \begin{document} \lipsum[1-3] \lipsum[1] New paragraph, which is really long, so long in fact that it spans more than one line. New paragraph, which is really long, so long in fact that it spans more than one line. \footnote{Here's a really long footnote that will probably be longer than one line, which could help to show the problematic behaviour. Here's a really long footnote that will probably be longer than one line, which could help to show the problematic behaviour. Here's a really long footnote that will probably be longer than one line, which could help to show the problematic behaviour. Here's a really long footnote that will probably be longer than one line, which could help to show the problematic behaviour.} % \lipsum \end{document} Current result: What I would like: some kind of symbol (perhaps a ➤?) at the end of the first page, showing that the footnote continues elsewhere and isn't just broken off. \usepackage[splitrule]{footmisc} indicates on the next page that there's a continuation, but I would like a marker on the first page as well. This question, this question, and this question ask the same thing, but none of them includes a MWE; I'm hoping that providing one will help find an answer.

I have a large book (750 pages) in a single file. One single file has advantages, like search/replace the entire TeX file without need of fancy multifile search features. But multiple files have the advantage of \includeonly feature: preserve counters (which preserves typesetting), faster compilation of fewer pages when fine-tuning. I wonder if there is a implementation of such \includeonly-like feature in single file documents, so I could (for instance) compile one chapter per time, preserving counters. Any thoughts? Edit: Another solution could be a set of macros that saves and restores the state of counters, like \includeonly does. If this is not implemented, maybe I could do it, but I prefer a ready-to-use solution, if any. M"W"E: if I omit or change argument of \includeonlyParts, I would get feature like \includeonly. \documentclass{report} \usepackage[T1]{fontenc} \providecommand{\savecounters}{} \providecommand{\restorecounters}{} \providecommand{\breakdoc}[1]{} \providecommand{\includeonlyParts}[1]{} \includeonlyParts{breakpoint-2} \begin{document} \breakdoc{breakpoint-1} \chapter{First} text \breakdoc{breakpoint-2} \chapter{Second} \breakdoc{breakpoint-3} \chapter{Third chapter} \end{document}

I like to use something like \,mathrm d t for the differential in an integral. That is, upright d for the differential symbl, with a bit of spacing before it, and then the variable t: However, the final t is too close to the d (I think they end up that close partly because the "d" is roman and the "t" is italic. Also, I'm using mathptmx in this example, but the question is in general). If I include \, between them, they become too separated: How can I easily get a fraction of the \, spacing in math mode? Ideally, for consistence, without manually specifying units like millimeters. For instance, something like \,[.4] (?) meaning "40% of the spacing provided by \,".

Consider the following MWE. \documentclass{beamer} \usepackage{tikz} \begin{document} \begin{frame} \begin{onlyenv}<2>% \tikz [remember picture, overlay] \node (A) {A};% \hskip 5em \tikz [remember picture, overlay] \node (B) {B};% \tikz [remember picture, overlay] \draw (A) -- (B);% \end{onlyenv}% \end{frame} \end{document} It produces the expected output (an empty page followed by one where A and B are connected by a line), but produces two unusual warnings. Package pgf Warning: Returning node center instead of a point on node border. D id you specify a point identical to the center of node ``B''? on input line 17. Package pgf Warning: Returning node center instead of a point on node border. D id you specify a point identical to the center of node ``A''? on input line 17. The warning is surprising because usually in TikZ, writing (A) is equivalent to writing (A.center). Indeed, the warnings only seem to appear in this rather particular case where the drawing is split over several tikzpictures (using remember picture), both points ((A) and (B)) have the same coordinates ((0,0) in this example) and there is an overlay where the picture is not drawn (here the first one). Why is there a warning here? Is this a bug? If so, in TikZ or in beamer? Is there an easy way to avoid it (without changing the drawings)?

I have something like \parbox[b]{0.924\textwidth}{ SPACE\dotfill\quad\\bar\quad\SPACE } I want the space on the left to be a fixed amount of physical space so that the beginning of the dotfill lines up with that of another parbox which has \hangafter=1 and \hangindent=1em. However, I want the space at the right to be variable such that the expansion of \bar is flushright in the box. The problem is that \dotfill chooses one dot too few rather than one too many (which is good) if the expansion of \bar is not flushright. I can fool around with inserting space manually but that’s finicky.

Just out of interesst, I asked myself how to configure a muxdemux such that it has the exact same dimensions as an european resistor (european inductor), but with three muxdemux-pins on the underside. (Note: The exact target image is attached.) Here is my approach: \documentclass[border=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european resistors, IPP/.style={muxdemux, muxdemux def={Lh=0.8, Rh=0.8, NL=1, NR=1, NB=3, NT=0, w=2}, %muxdemux label={B2=abc, BL1=1, BL2=2, BL3=3,}, %external pins width=0.4, circuitikz/muxdemuxes/fill=gray!25, }, ] \node [IPP, align=center](A) at (0,0) {}; \draw[] (-1,0.5) to[R, fill=gray!25] +(2,0); \end{circuitikz} \end{document}

Is there a way to raise an integral sign slightly and bring the limits together with it? For example, in \documentclass{report} \begin{document} \[ \int_0^1 \sqrt{a+b\sqrt{a+b\sqrt{a+b\sqrt{x}}}} dx \] \end{document} the integral can benefit from being enlarged and moved up a small bit, even if it going to take it out of alignment with part of the formula.

I want to make the following diagram: But this: \documentclass[a4paper,12pt]{article} \usepackage[compat=1.1.0]{tikz-feynman} \usepackage{xcolor} \definecolor{uctgreen}{rgb}{0,0.45,0} \newcommand\uct[0]{{\color{uctgreen}{u}\color{red}{c}\color{blue}{t}}} \tikzfeynmanset{ every diagram={very thick}, } \begin{document} \resizebox{5cm}{5cm}{ \begin{tikzpicture}[yscale=0.7, xscale=1.4] \begin{feynman} % ~~~ defining the vertices ~~~~~~ \vertex (i1) ; \vertex[below right=of i1] (v1); \vertex[ right=of v1] (v2); \vertex[above right=of v2] (o1); % ~~~ Z-related ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \vertex at ($(v1)!.5!(v2) - (0,15mm)$) (v3); % middle, below \vertex[below=1cm of v3] (v4); % <<< Z "length" % ~~~ lower part ~~~~~~~~~~~~~~ \vertex[below left = 2cm of v4] (i2); % one way to modify \vertex[below right= 2cm of v4] (o2); % ~~~ drawing this diagram ~~~~~~~~~~~~~~~~~~~~~ \diagram*{ {[edges={fermion}](i1) --[edge label=s] (v1) --[edge label=\uct] (v2) --[edge label=d] (o1)}, (v1) --[photon, half right, edge label'=W] (v2), (v3) --[photon, edge label'=Z] (v4), {[edges={fermion}](i2) --[edge label'=$\nu$] (v4) --[edge label'=$\nu$] (o2)}, }; \end{feynman} \end{tikzpicture} } \end{document} produces this: How can I add labels to both sides of the W and make the W-Z vertex match up?

I am experiencing a persistent issue with page headers when using longtable. Section and subsection titles normally appear correctly in the header, but as soon as a longtable is introduced, the header stops updating. All subsequent pages keep showing the previous header, even after new \subsection commands. This does not happen with figures or normal tables, only with longtable. Reordering content confirms the issue: if figures come before the longtable, headers are correct; if they come after, headers are broken. I understand that longtable interferes with marks, but I have not found a robust solution that works in practice. Note that this behavior appears only when longtable spills onto mutliple pages. \documentclass{article} \usepackage{geometry} \usepackage{fancyhdr} \usepackage{longtable} \usepackage{booktabs} \pagestyle{fancy} \fancyhf{} \fancyhead[L]{\small\scshape\rightmark} \fancyfoot[C]{\thepage} \renewcommand{\sectionmark}[1]{% \markright{\thesection\quad #1} } \renewcommand{\subsectionmark}[1]{% \markright{\thesubsection\quad #1} } \makeatletter \patchcmd{\LT@array}{\@mkboth{}{}}{}{}{} \makeatother \begin{document} \section{Test section} \subsection{First subsection} Some text. \newpage \subsection{Subsection before longtable} Some text. \newpage \subsection{Longtable here, header never shows up} \begin{longtable}{ll} \toprule A & B\\ \midrule \endfirsthead \toprule A & B\\ \midrule \endhead 1 & 2\\ 3 & 4\\ 5 & 6\\ 1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ 3 & 4\\ 5 & 6\\1 & 2\\ \bottomrule \end{longtable} \newpage \subsection{Header must update} This header updates. \end{document} With resulting issue: I have tried using with no success: % Page style \newpagestyle{main}{ \setheadrule{.55pt} \sethead{\small\scshape\rightmark}{}{} \setfoot{}{\thepage}{} } % Subsection marks \renewcommand{\subsectionmark}[1]{% \markright{\thesubsection\quad #1} } \usepackage{etoolbox} \renewcommand{\subsectionmark}[1]{% \markright{\thesubsection\quad #1}% } \makeatletter \patchcmd{\LT@array}{\@mkboth{}{}}{}{}{} \makeatother Expected behavior: The page header should update to the current subsection title after a longtable, exactly as it does after figures or standard tables. Question: Is there a robust and recommended way to use longtable without breaking page headers? Or is this a fundamental limitation of longtable and marks?

There is a lot of information on how to make beautiful documents with LaTeX. However, I am thinking about setting up a note taking workflow and I purposely want to make things look messy. I suppose what I want to signal is that rough notes look messy, and that as I develop ideas into papers, as the narrative and reasoning get stronger and better, I can improve the aesthetics, so that beautiful content looks beautiful and rough content looks rough. What sort of settings do you all recommend for messy LaTeX output? I'm thinking bad line breaks, bad page breaks, ragged margins, poor or perhaps just thoughtless placement of floats, different fonts/colours for different environments (and even random switches in font/colour, within certain parameters ... the notes should still be readable, of course). I would like to mimic a "messy aesthetic" for note taking, which is easy enough to do with pen and paper. Marginal notes rotated. I'm sure there are hundreds of possibilities. It might be an interesting project to think of a spectrum, most messy look for most messy thinking, through some mid-range mess for improved thinking, eventually to most beautiful for most well-thought out and correct thinking. I plan to use Emacs org-mode or org-roam (which is already well on its way in the mess category 🙂 ) with export to LaTeX and then to PDF. But I also use pure LaTeX regularly. Edit: for an idea of what I'm looking for, here are a couple of Pinterest boards. https://www.pinterest.com/ideas/messy-school-notes-aesthetic/895918930715/ https://in.pinterest.com/search/pins/?q=notes%20messy%20aesthetic&rs=typed Note that all the examples are with physical pen and paper; I would like to simulate such a thing with LaTeX -> PDF.

I know that MathJax is a not-entirely-faithful subset of TeX, and that converting packages from LaTeX to MathJax is non-trivial and involves JavaScript. The MathJax documentation does exist, but it is difficult to parse for someone not immersed in it (which is common). It is also not obvious what one needs to do to implement a particular TeX macro so it works in MathJax. Can anyone recommend a "walk-through," example, or good description of how to translate a LaTeX package into a MathJax extension?

We try to reference a line in a shy algorithm and the algorithm itself with zref-clever. Running pdflatex twice on \documentclass{article} \pagestyle{empty} \usepackage{hyperref} \usepackage{algorithm2e} \usepackage{zref-clever} \zcRefTypeSetup{algocf}{ name-sg=Alg.\@, Name-sg=Alg.\@ } \zcRefTypeSetup{AlgoLine}{ Name-sg=line, name-sg=line } \zcRefTypeSetup{algocfline}{ Name-sg=line, name-sg=line } \zcRefTypeSetup{line}{ Name-sg=line, name-sg=line } \begin{document} \begin{algorithm}\LinesNumbered \caption{My great algorithm}\label{algLabel} \KwOut{The oh so great output of my great algorithm} command1\; command2\nllabel{lineLabel}\; command3 \end{algorithm} \zcref[S]{algLabel} contains \zcref{lineLabel}. \end{document} yields As we see, the second type name is “Alg.”, whereas we'd expect “line”. If we comment out hyperref, we get “Alg. 1 contains line 2.” as expected. So far we failed to get different type names for the two references in the presence of hyperref, so you can blame it. At the same time, given that algorithm2e has been unmaintained for about 8½ years and zref-clever for slightly over 1 year, you can blame them, too. Anyway, what is the technical root cause of the failure? Any bugfix, patch, or workaround?

I'm having a difficult time understanding the vertical alignment of columns of tables created via tabular. My Code \documentclass{article} \usepackage{array} \begin{document} \begin{tabular}{ | p{2.5cm} | m{2.5cm}| b{2.5cm} | } \hline cell1 dummy text dummy text dummy text& cell2 & cell3 \\ \hline cell4 & cell5 dummy text dummy text dummy text & cell6 \\ \hline cell7 & cell8 & cell9 dummy text dummy text dummy text\\ \hline \end{tabular} \end{document} This example is pretty much taken directly from the Overleaf Tables documentation, with the difference being the varying column alignments. I'd expect the code above to produce Expected table with the text in the first column top-aligned, the text in the second column middle-aligned, and the text in the third column bottom-aligned. However, the code above actually produces Actual table I know it's possible (and easier) with the tabularray package, but I'd like to understand why. Why do my actual table's columns have seemingly incorrect vertical alignments?

I'm trying to plot a rational function, but I constantly get dimensions too large, even if the plot frame is within the page and the function is within limits. \documentclass{book} \usepackage{pgf,tikz,pgfplots} \pgfplotsset{compat=1.15} \begin{document} \begin{tikzpicture}[declare function={r(\x)=(-\x*\x*\x*\x+600*\x*\x*\x-135000*\x*\x+10125000*\x)/(2109375*(30000-200*\x));}] \begin{axis}[ x=0.05cm,y=1cm, xmin=0, xmax=160, ymin=0, ymax=1, xlabel={\(x\)}, ylabel={\(y\)} ] \draw[domain=0:160,smooth,samples=100] plot ({\x},{r(\x)}); \end{axis} \end{tikzpicture} \end{document} What could be wrong? TIA. This is how the graph looks in Mathematica

I am designing a book cover using bookcover documentclass and would like to add a 4"x4" pdf graphics file in the center of the cover.
