I am trying to speed up the compilation of a complex project using a format file and tikz externalize. In particular I tried a setup like shown in the follwing MWE: preamble-min.tex \documentclass[a4paper,12pt]{article} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usetikzlibrary{external} \dump main-min.tex: \tikzset{ external/system call={% pdflatex -shell-escape -fmt=preamble-min \ -interaction=nonstopmode -jobname "\image" "\def\tikzexternalrealjob{\texsource}\input{\texsource}"% } } \tikzexternalize[prefix=tikz-cache/] \begin{document} \begin{tikzpicture} \begin{axis} \addplot+[raw gnuplot, mark=none] gnuplot { plot [-5:5] sin(x); }; \end{axis} \end{tikzpicture} \end{document} Compilation Steps: mkdir -p tikz-cache pdflatex -ini -shell-escape -jobname=preamble-min "&pdflatex preamble-min.tex" pdflatex -shell-escape -fmt=preamble-min main-min.tex The compilation stops with: ! Incomplete \iffalse; all text was ignored after line 19. <inserted text> \fi <*> main-min.tex Any ideas how to make this work well and robust? I am using texlive-2025.

I'm using q.uiver.app to make commutative diagrams for a project. There is a feature that allows for the label of an arrow to be displayed directly above it. This creates a white background for the label, which clashes visually with the background box. Here is an example of what it looks like: Here is an example of the code for the commutative diagram, using {description} to overlay the text above the arrow: \[\begin{tikzcd} Q &&& \\ & P && X \\ \\ & {X'} && Y \arrow["{\exists!h}"{description}, dashed, from=1-1, to=2-2] \arrow["p"{description}, from=1-1, to=2-4] \arrow["q"{description}, from=1-1, to=4-2] \arrow["a"{description}, from=2-2, to=2-4] \arrow["b"{description}, from=2-2, to=4-2] \arrow["f"{description}, from=2-4, to=4-4] \arrow["g"{description}, from=4-2, to=4-4] \end{tikzcd}\] I'm using a template for the project; here is what the stylesheet uses to define the lemma/proof boxes: % proofs: proof \definecolor{prooflinecolor}{RGB}{103, 103, 103} % rgba(40, 40, 40, 180) %FORMAT \definecolor{proofbgcolor}{RGB}{247, 247, 247} % rgba(40, 40, 40, 10) %FORMAT \linedbox{@proof}{Proof}{proof}{proofbgcolor}{prooflinecolor} % this numbers the proofs, so we renew the environment to prevent that; but we still allow a title, so you can do e.g. "Proof (of Theorem 1.2.3)" \def\qed{\null\nobreak\hfill\ensuremath{\blacksquare}} % qed square %FORMAT switch \blacksquare to \square for the not-filled-in version \renewenvironment{proof}[1][]{\csname @proof*\endcsname{#1}{}}{\qed\csname end@proof*\endcsname} \def\flushproof{\vspace{-\parskip}} % put this before a proof to make it flush with the result it's proving How do I make this white background transparent? Or, if necessary, how do I set it to a certain colour (so that I can just choose the backdrop colour)?

I was scrolling through reels earlier and came across a really cool animation: https://www.youtube.com/shorts/aQbq_Fpyyb4. Note: You can analyze the gif frame by frame using the method suggested by MS-SPO in the comments, or by using the website ez-gif, or by using custom python scripts. I interchangeably use ez-gif and python for these sorts of things, and in this instance used ez-gif. I did some digging and found this old post, which I modified slightly. % Source - https://tex.stackexchange.com/a/205608 % Posted by Mark Wibrow % Retrieved 2026-03-22, License - CC BY-SA 3.0 \documentclass[tikz, border=5]{standalone} \usetikzlibrary{lindenmayersystems} \tikzset{koch snowflake/.style={insert path={% l-system [l-system={rule set={F -> F-F++F-F}, axiom=F++F++F, step=0.75cm/3^#1, angle=60, order=#1,anchor=center}] -- cycle}}} \begin{document} \begin{tikzpicture} \path[fill=orange,koch snowflake=4]; \end{tikzpicture} \end{document} I am however without a clue as to how to go about producing this gif I found. I am seeking assistance in creating this gif.

I'm trying to generate texfonts.h from mimetex package. According to documentation I execute next TeX/METAFONT commands: mf "\mode=eighthre; input cmr10" # produces cmr10.83gf gftype -i cmr10.83gf > typeout Most of chars looks as expected (latin letters, capital Gamma and Theta), but capital Delta looks strange. See fragment of typeout file: 1561: beginning of char 0 .<--This pixel's lower left corner is at (0,8) in METAFONT coordinates ****** * * * * * * * * *** .<--This pixel's upper left corner is at (0,0) in METAFONT coordinates 1588: beginning of char 1 .<--This pixel's lower left corner is at (0,8) in METAFONT coordinates * * * * * ** ** * * * * * * .<--This pixel's upper left corner is at (0,0) in METAFONT coordinates 1623: beginning of char 2 .<--This pixel's lower left corner is at (1,8) in METAFONT coordinates ** * * * * * ** * * * * * * * ** .<--This pixel's upper left corner is at (1,0) in METAFONT coordinates If I repeat the same, but use mode=preview, Delta looks ok also. Whether this is sort of bug? If yes, and if I understand correctly, cmr10.mf includes roman.mf, which includes greeku.mf, where description of how to draw Δ is placed. But I can't understand syntax and unable even to determine, whether first step (mf) or second (gftype) cause error. Anyway, seems this files weren't updated recently. I have almost no knowledge about TeX fonts, just want to repeat abovementioned header file. Most of letters for cmr10.83 converted successfully (i.e. I got same hex representation), but not this Delta.

when defining a figure that holds a table of images, how do i ensure even and symmetric padding when using \hline in it? by default, there's no padding before the row that was \hlined. i have the following MRE: \documentclass{article} \usepackage{array} \usepackage{graphicx} \newcolumntype{I}{>{\centering\arraybackslash}m{0.18\linewidth}} % simulate images \newcommand{\fakeimg}{\rule{\linewidth}{2.5cm}} \begin{document} \begin{tabular}{c I I I} & A & B & C \\ row1 & \fakeimg & \fakeimg & \fakeimg \\ \hline row2 & \fakeimg & \fakeimg & \fakeimg \\ \end{tabular} \end{document} this produces the following image, where the rule is stuck tightly to the images on the second row: how do i define the padding in a controlled (tunable) manner so that the optional rule perfectly divides it in half (i want to add the divider only between specific pairs of rows)? i've tried interjecting a bunch of artifical spaces and padding in the rows before/after, but they all break apart when i wish for a small-scale padding of, say, 0.3ex: my attemps yield assymetrical padding where the padding before second row is smaller than padding after the first row.

While writing paper, I found that abnormal vertical blank space appears at the bottom of footnotes in the first column of the cas-dc template. Even after replacing the original paper content with other characters, the issue still persists, and the reproducible code provided below is just an example rather than the only scenario that triggers this problem. I am using TeX Live 2026 on the Windows system and compiling documents with pdflatex, and I aim to identify the root cause of this abnormal blank space and find corresponding methods to avoid it. \documentclass[a4paper,fleqn]{cas-dc} \begin{document} \shorttitle{} \title[mode=title]{consequat.

I'm new to luadraw and I'm trying to recreate the diagram below: Here is my code so far, and the result: % !TEX TS-program = LuaLaTeX \documentclass{standalone} \usepackage[3d]{luadraw} \begin{document} \begin{luadraw}{name=wedge} local a, b, c = 8, 6, 4 local xmax, ymax, zmax = a+1, b+1, c+1 local g = graph3d:new{ window3d = {0,xmax,0,ymax,0,zmax}, viewdir = {30,60}, size={10,10,0} } local xIntcpt, yIntcpt, zIntcpt = M(a,0,0), M(0,b,0), M(0,0,c) local P = M(4,0,0) local Q = interDD({P,vecJ},{xIntcpt,yIntcpt-xIntcpt}) local R = interDD({P,vecK},{xIntcpt,zIntcpt-xIntcpt}) g:Dscene3d( g:addPolyline({ {Origin,xmax*vecI}, {Origin,ymax*vecJ}, {Origin,zmax*vecK}, }), g:addPolyline( {xIntcpt,yIntcpt,zIntcpt}, {close=true,color="cyan"}), g:addFacet( {P,Q,R}, {color="cyan",opacity=0.5} ), g:addPolyline( {P,Q,R}, {close=true,color="cyan",style="dashed"} ), g:addLabel( "\\(x\\)",P,{pos="NW",dist=0.1}, a,xIntcpt,{pos="NW",dist=0.1}, b,yIntcpt,{pos="N",dist=0.1}, c,zIntcpt,{pos="NW",dist=0.1} ) ) g:Show() \end{luadraw} \end{document} The issue, as you can see, is that the point (0,6,0) is out of frame. I tried increasing ymax, that seems to have no effect. I tried changing the width in the size option, but that only stretches the diagram horizontally. I have tried different viewdir options, but they all cut the diagram off at one edge. I'm sure it's something basic that I'm missing, but I'm too much of a novice to notice. Any clues?

I need to align the \closing{} of the letter package with the body of the letter, on the left, while keeping the \signature{} but this code is actually removing the \signature{} from the rendered document: \documentclass[a4paper]{letter} \signature{Your Name} \address{Your Address} \date{\today} % I renew the closing command here, before beginning the document: \renewcommand{\closing}[1]{\par\noindent#1\par} \begin{document} \begin{letter}{Recipient Name \\ Recipient Address} \opening{Dear Sir or Madam,} This is the body of the letter.

When using fractions in \polylongdiv, the vertical spacing turns out rather awkward. If no fractions are used for the coefficients, the spacing is fine. I have tried to adjust the vertical spacing using arrayrowsep=..., but without any visible change.

I have a working exercise/solution engine based on that from the tcolorbox documentation and it works perfectly. There is one thing I would like to change if possible. In my MWE, I create three exercises and their corresponding solutions and I also create new autorefnames for their respective counters. The exercises are in two different sections but all the solutions are in a new section and that causes the solution numbers typeset when I cite them with \autoref to reflect the new section, not the sections of the corresponding exercises. In other words, the names of the solutions to Exercise 1.1 and Exercise 2.1 typeset as Solution 3.1 and Solution 3.2 whereas I would like them to be Solution 1.1 and Solution 2.1 respectively even if they are in the third section. I think my question is: can I make a solution's number retain the value of the number of its corresponding exercise even when the solution is in a different section of the document? I have experimented and nothing I have tried works. This is for a larger book project and I can live with the situation but I want to know if my question has a relatively simple answer.

I would like to use Initials in a nice poetry book and need for German Umlaute (Ä Ö Ü) those designs.

I need all binomial coefficients for n=1..100 and k=1..100 several times, so I wrote a code with xint: \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; I measured out for that: ******************************************** *** TOTAL COMPILATION TIME REPORT: *** (l3benchmark) + TOC: 2.27 s ******************************************** This is OK, but I asked myself: Is there any way I can store the array (in a file?) so that it doesn't have to be recalculated on every new run? \documentclass[paper=a5, paper=landscape]{scrarticle} \usepackage[margin=10mm]{geometry} \usepackage{xintexpr} \usepackage{amsmath} \begin{document} \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; %Test: \xinteval{BinomialArray[100-1,50-1]} works Test: $\dbinom{100}{50}=\xinteval{abinomial(100, 50)}$ % Show complete array - on your own risk :() %\newpage %\begingroup %\tiny %BinomialArray = \xintthealign\xintexpr BinomialArray\relax %\endgroup \end{document}

As what my knowledge could tell, It's possible to create a triangle with only 2 coordinates to make real angles to be exact, and using path to create long rays and naming the intersection of those rays and finally connect them with \draw. MWE: \documentclass[tikz, border=10pt]{standalone} \usepackage{siunitx} \usetikzlibrary{intersections} \begin{document} \begin{tikzpicture}[scale=2] \clip (0,0) rectangle (5,2.1); \coordinate (A) at (0,0); \coordinate (C) at (5,0); \path[name path=AB] (A) -- ++(37:4); \path[name path=BC] (C) -- ++(137:4); \path[name intersections={of=AB and BC, by=B}]; \draw[thick] (A) -- (B) -- (C) -- cycle; \end{tikzpicture} \end{document} There is a noticable difference if I comment \clip in the 6th line. Without it, it's going to be a white space... It's impractical to calculate the height of the object if I make another drawing with more complicated shape. So, is it possible to autocrop the exceeding lines? What I meant by exceeding lines is like the cyan lines in the figure below. It's because they contribute to white space if I change \draw to \path: So, if possible, I want TikZ to automate cropping the intersection, in other words, getting rid of those exceeding lines without estimating like how much the height is (would consume loads of time if I make other complicated figures with intersections). To illustrate what I actually want, roughly I want something like this: Yes, I deliberately cropped it poorly to give an example as to what it shows if I gave them an incorrect clipping, which I wish I didn't need to clip it, but instead, I wish TikZ only read the intersection point and two given coordinates to draw.

I am creating an accessible PDF using tagpdf as follows: \DocumentMetadata{ lang = fr-FR, pdfversion = 2.0, pdfstandard = ua-2, pdfstandard = a-4f, %or a-4 tagging = on, tagging-setup={math/setup=mathml-SE} } \documentclass[a4paper,11pt]{article} % Page layout \usepackage[margin=2.5cm]{geometry} \usepackage{pdfpages} % General information \author[]{YamiOmar88} \title{Some Title} \date{} % remove semantic paragraphs: \AssignTaggingSocketPlug{para/semantic/begin}{noop} \AssignTaggingSocketPlug{para/semantic/end}{noop} \begin{document} % --- Poster pages (NOT accessible, marked as artifacts) --- \tagstructbegin{tag=Artifact, alt={Tableau de bord non accessible}} \includepdf[pages=1, fitpaper=true, artifact]{example-image.pdf} \includepdf[pages=1, fitpaper=true, artifact]{example-image.pdf} \tagstructend \end{document} I include pages from another PDF file using the pdfpages package and the command \includepdf. Here, for this example I'm always including the same page #1 and using a sample image to be able to compile it. When I look at my tags I see this: <Document> <Private> <Figure> <p> <Figure> <p> As I declared the artifact, the <Private> tag shows the appropriate alt-text. However, the <Figure> tags contain the path to the image as alt text. How can I change that? I do not want that path to be made public. And what are the <p> tags? Where did they come from? Note: The code is compiled with LuaLaTeX using MiKTeX 26.2. My LaTeX version is LaTeX2e <2025-11-01>, L3 programming layer <2026-01-19>.

But in this particular file I'm working, it would make more sense for it to be at the same level as the <Sect> tag instead of inside it. Is this possible? In other words, I want this: <Document> <p> <p> <Sect> <H1> <p> <Private> instead of this: <Document> <p> <p> <Sect> <H1> <p> <Private> Note: The code is compiled with LuaLaTeX using MiKTeX 26.2. My LaTeX version is LaTeX2e <2025-11-01>, L3 programming layer <2026-01-19>.

I wish to draw something like this: I can draw the two lines, though it is difficult to be precise. However I don't know what to do next as for the dashed line and the arrow line. The dashed lines are perpendicular to MK and JL, but the arrow line are parallel to those lines. And the difficult part is connecting the dashed line with the arrow line. I failed to draw the 90 degree sign, it looks too big and ugly. My attempt: \documentclass[tikz,border=3pt]{standalone} \usepackage{amsmath} \usetikzlibrary{calc,intersections,angles,quotes,arrows.meta} \begin{document} \begin{tikzpicture}[line cap=round,line join=round,>=Stealth] % ---------- circle ---------- \def\r{3.0} \coordinate (O) at (0,0); % points on the circle chosen by polar coordinates % (this is the important part) \coordinate (J) at (86:\r); \coordinate (M) at (142:\r); \coordinate (L) at (232:\r); \coordinate (K) at (332:\r); % circle \draw[black,line width=0.9pt] (O) circle (\r); % ---------- cyan lines ---------- \colorlet{mycyan}{cyan!70!blue} % main solid chords \path[name path=JL] (J) -- (L); \path[name path=MK] (M) -- (K); \draw[mycyan,line width=1.1pt] (J) -- (L); \draw[mycyan,line width=1.1pt] (M) -- (K); % intersection N \path[name intersections={of=JL and MK, by=N}]; % ---------- right-angle mark at N ---------- \coordinate (Nu) at ($(N)!0.42!(M)$); \coordinate (Nv) at ($(N)!0.42!(J)$); \coordinate (Nw) at ($(Nu)+(Nv)-(N)$); \draw[black,line width=0.8pt] (Nu) -- (Nw) -- (Nv); % ---------- center ---------- \fill (O) circle (2.2pt); % ---------- labels ---------- \node[font=\fontsize{21}{21}\selectfont] at ($(J)+(0.02,0.35)$) {$J$}; \node[font=\fontsize{21}{21}\selectfont] at ($(M)+(-0.45,0.08)$) {$M$}; \node[font=\fontsize{21}{21}\selectfont] at ($(L)+(-0.28,-0.18)$) {$L$}; \node[font=\fontsize{21}{21}\selectfont] at ($(K)+(0.5,-0.02)$) {$K$}; \node[font=\fontsize{21}{21}\selectfont] at ($(N)+(0.38,0.02)$) {$N$}; \node[font=\fontsize{25}{25}\selectfont] at ($(O)+(0,-0.55)$) {$O$}; \end{tikzpicture} \end{document} Also, explain to me what the trick is, so that I can implement it in other cases.

Working on a timeline for a legal case in which all events occurred over five months. So far, I have twelve events and two time periods, and I still need to add more.

I'm a PhD student evaluating cloud LaTeX editors for writing my dissertation. I've used Overleaf for years but I'm noticing a new wave of editors claiming AI-powered features. I've looked at: Overleaf — familiar, but not reliable, and compilation is slow on large documents OpenAI Prism — new, AI-native, backed by OpenAI (I don't trust OpenAI) Papeeria — free tier, minimal AI Bibby AI (trybibby.com) — seems focused on bibliography error detection specifically with a good AI benchmark they published outperforming OpenAI and Overleaf. My question is: for someone writing a 200-page dissertation with 300+ citations, what are the meaningful technical differences between these editors, particularly: How does real-time bibliography validation differ across platforms? Do any of them integrate with arXiv directly? Is AI autocomplete in LaTeX actually useful or is it mostly marketing?

The ltx-talk class for slides defines its own basic lists, so that they can be used with overlays. I am interested in using custom lists, for example ones that pre-format dialogue. Doing this in the usual way with enumitem currently fails. A brief example follows. Is there a way to insulate custom lists from the class's baked-in list definitions, so that this will work, by putting them in something like a minipage environment? Failure case \DocumentMetadata{tagging = on, lang = en-us} \documentclass[aspect-ratio=4:3]{ltx-talk} \usepackage{enumitem} \newlist{dialist}{description}{1} \setlist[dialist]{font=\textsc, leftmargin=2cm, style=nextline} \begin{document} \begin{frame} \frametitle{Dialogue} \begin{dialist} \item[Socrates] And your opinion is right, as you can prove in this way: if some one asked you “Is there, Gorgias, a false and a true belief?” you would say, Yes, I imagine. \item[Gorgias] I should. \item[Socrates] But now, is there a false and a true knowledge? \end{dialist} \end{frame} \end{document} error: !

A follow up question to How to modify the chapter headings using \EditInstance. The accepted answer solved the basic layout, but how can I eliminate the vertical space between the top of the text area and the top rule of the chapter heading when using the ruled headformat? The code written by cfr in the linked question produces The current output has unwanted space above the top rule (see image above), while I want the rule to align with the top of the text area (see image below).

I want to draw a commutative diagram like the figure below using xy-pic package. But I don't know how to draw a vertical arrow \mapsto in xy-pic. Edit: \documentclass{article} \usepackage[all,cmtip]{xy} \newcommand{\tuple}[1]{\langle #1 \rangle} \begin{document} \[\begin{xy} {\ar@{|->}(0,0)*{};(10,0)*{}}; \end{xy}\] \end{document} I know how to draw commutative diagrams in the \begin{CD} ... \end{CD} environment. But I have a big problem understanding the order of commands in xy-pic

I am using babel package with Spanish style (in amsart class), which puts acute accents in math symbols such as \lim, \max, \inf, etc. It is actually nice, because it keeps all the formatting in the same language and style. However, it doesn't put the accent in \varprojlim, which doesn't go with the general layout. Is it possible to make \varprojlim have the accent as everything else? MWE: \documentclass{amsart} \usepackage[spanish]{babel} \usepackage{amssymb,amsfonts,amsmath} \begin{document} \[ \lim \; \inf \; \max \] \[ \varprojlim \] \end{document} Result:

It seems (or is apparently) that thickness of lines is hard coded. Consequently when drawing a line, the use for example of scale=2 only makes the line longer and its thickness is not changed, see MWE below: \documentclass[margin=3mm, varwidth]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \tikzset{LA/.style = {-Straight Barb, line width=1mm}} \begin{document} \begin{tikzpicture} \draw[LA] (0,0) -- ++ (2,0); \end{tikzpicture} \begin{tikzpicture}[scale=2] \draw[LA] (0,0) -- ++ (2,0); \end{tikzpicture} \end{document} Is there some trick by which the thickness of the line will also be scaled? The best way would be as option of the line style, which will have effect just on this particular line. My quick search on this site so far didn't give me any suggestion ...

The following loop is an example of a loop that, starting from a certain sequence member, is rounded to 1.0000. How can I break the loop at the second term, which is 1.0000 (in this example, that's the 13th)? Note: I'm using TikZ and xint; both are possible options. \documentclass[margin=5pt, varwidth]{standalone} \usepackage{tikz} \usepackage{xintexpr} \begin{document} \foreach \x in {1,...,15}{%% \x: \xintround{4}{\xinteval{1-exp(-\x/1.2)}}\par }%% \end{document}

I'm creating a landscape booklet with top ring binding, and I want it to be read across both pages when opened. I've been trying to set up inner and outer margins, but the information I find mostly covers how to do this when the book is bound on the left edge. What I need is to have different top and bottom margins for odd and even pages, like: Odd pages: 25mm top margin, 10mm bottom margin Even pages: 10mm top margin, 25mm bottom margin I’ve tried using the memoir and book classes, along with geometry, but I’m open to other suggestions as well. Could someone explain the recommended setup for this kind of book format? Any help would be greatly appreciated! A (blurry, will update..) picture of the layout I am thinking of. Thanks!

I draw an arrow with a label like this. \documentclass[dvipdfmx]{article} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[auto=left] \node[name=A] at (0,0) {$A$}; \node[name=B] at (1,0) {$B$}; \draw[->] (A) -- (B) node[pos=0.5]{$f$}; \end{tikzpicture} \end{document} I like this notation because the order is “a coordinate, a coordinate, and a label.” This is more readable than “a coordinate, a label, and a coordinate.” I want to bend the arrow while keeping this order. I tried the following: \documentclass[dvipdfmx]{article} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[auto=left] \node[name=A] at (0,0) {$A$}; \node[name=B] at (1,0) {$B$}; \draw[->] (A) to[bend left=30] (B) node[pos=0.5]{$f$}; \end{tikzpicture} \end{document} However, this does not work properly—the label appears at coordinate A. I know I can achieve this with a \newcommand, but is there another way? Thank you.
