Consider the code: \documentclass{book} \usepackage{graphicx} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \thispagestyle{empty} \begin{center} \begin{tikzpicture} \fill[red] rectangle (8,6); \foreach \k in {0,30,...,360} \node at ($(4,3)+(\k:2)$) {\includegraphics[width=1.7em]{example-image-a}}; \end{tikzpicture} \end{center} \end{document} which produces: QUESTION: How may I modify this code in order produce an ellipse (instead of circle) of images? Thank you.

Consider the following code: \documentclass{article} \usepackage{tikz} \usetikzlibrary{% decorations.text,% mindmap,% } \begin{document} \begin{tikzpicture} \path[ adddecrev/.style={% postaction={decorate, decoration={text along path, text={##1}, raise=3pt, }}}, small mindmap, ] node (norm) [root concept, concept, adddecrev={AAA AAA|\hskip 7.5pt| ||AAAAA AAA{\kern10ptA}A AA AA}] {AAAAAAAAA} [counterclockwise from=120] % removing this child eliminates the warnings child { node [concept, adddecrev={X{\kern-2ptX}{\kern-1ptX}{\kern4ptX}{\kern0ptX}X|\hskip8pt| ||X{\kern-2ptX}X{\kern-1ptX}{\kern-1ptX} X{\kern-3ptX}{\kern-1ptX}l{\kern-1ptX}|\hskip-2pt|X||{\kern-1ptX}|\hskip4pt|X||{\kern-2ptX}|\hskip-2pt|X|| }] {MMMMMMMM} } ; \end{tikzpicture} \end{document} In TL2020, this compiles without complaint for either pdfLaTeX or LuaLaTeX. In TL2025 or 2026, it complains Missing character: There is no A in font nullfont! In TL2024, the complaint is Missing character: There is no @ in font nullfont! In TL2022 and TL2023, the complaint is Missing character: There is no ? in font nullfont! In TL2021, the complaint is Missing character: There is no > in font nullfont! What causes these differences? Usually the nullfont warnings relate directly to problematic characters in the source. The A suggests that might be the case, except that removing the X line makes the problem disappear. Moreover, for earlier installations, the characters complained of bear no obvious relation to the input and I'm not sure where they are coming from or what the problem is. I also can't see anything obviously wrong with the code specifying the text for the decoration, despite rereading the relevant part of the manual. What is happening here? Is my code erroneous? If so, how can I correct it? In any case, is there a way to avoid the problem with a current TeX Live?

Starting from \documentclass[a4paper,12pt]{article} \usepackage{mathtools} \begin{document} \[ \begin{cases} x=x(t) & t\in[a,b]\\ y=y(t) \end{cases} \begin{cases} x=x & x\in[0,\pi/3]\\ y=y(x) \end{cases} \] \end{document} I would have this: putting the parameter in the middle between the two equations of the system. And if I had n equations, what would be the way to put it in the middle?

I would need your help to draw a surface of genus three like in the picture I attached. More specifically, I aim to draw a torus (surface of genus one) and below the surface of genus three realised by mean of some surgeries on the surface. I already drawn the torus by myself and I need help with the genus 3 surface. As you can see, the torus I drew is not exactly as on paper. Could help me? I also added some notes about colours of curves. Moreover, I'd like the surface is filled with the pattern [pattern=north west lines, pattern color=pallido], where pallido is just a colour I defined in RGB (it's already in the code). In the picture I do not need the names of colours, that's only for you. Thank you in advance! \documentclass[11pt,a4wide]{article} \usepackage[latin1]{inputenc} \usepackage{fancyhdr} \usepackage{indentfirst} \usepackage{graphicx} \usepackage{newlfont} \usepackage{amssymb} \usepackage{amsmath} \usepackage{latexsym} \usepackage{lscape} \usepackage{booktabs} \usepackage{amsthm} \usepackage{lscape} \usepackage{tikz} \usetikzlibrary{patterns,hobby} \usepackage{pgfplots} \pgfplotsset{compat=1.6} \usepackage{faktor} %\faktor{A}{B} %\usepackage{pictexwd,dcpic} \usepackage{pgf,tikz} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usetikzlibrary{arrows.meta} \usetikzlibrary{decorations.markings} \usetikzlibrary{bending} \usetikzlibrary{patterns} \usetikzlibrary{intersections, calc} \usetikzlibrary{decorations.pathmorphing} \usepackage{soul} \usepackage{rotating} \usepackage[margin=3cm]{geometry} \usepackage{enumitem} \usepackage{color} \usepackage{hyperref} \definecolor{smoked}{RGB}{216, 212, 204} \definecolor{mauve}{RGB}{200, 55, 171} \definecolor{apricot}{RGB}{250, 144, 4} \definecolor{sky}{RGB}{66, 169, 244} \definecolor{plum}{RGB}{76, 0, 102} \definecolor{forest}{RGB}{90,145,120} \definecolor{sand}{RGB}{180,160,120} \begin{document} \begin{figure}[h!] \centering \begin{tikzpicture}[scale=2, every node/.style={scale=0.875}] \definecolor{pallido}{RGB}{221,227,227} \pattern [pattern=north west lines, pattern color=pallido] (0,0) ellipse (3cm and 2cm); \fill [white] (0,0) ellipse (1cm and 0.66cm); \draw[thin, black] (0,0) ellipse (3cm and 2cm) (0,0) ellipse (1cm and 0.66cm); \draw[orange] (0,0) ellipse (2cm and 1.25cm); %\draw[blue] (0,0) arc (030:060:2.5cm and 1.5cm); \draw[blue] (0,0) +(30:2.4 and 1.6) arc [start angle=30, end angle=60, x radius=2.4, y radius=1.6]; \draw[blue] (0,0) +(210:2.4 and 1.6) arc [start angle=210, end angle=240, x radius=2.4, y radius=1.6]; \draw[violet] (0,0) +(120:1.2 and 0.8) arc [start angle=120, end angle=150, x radius=1.2, y radius=0.8]; \draw[violet] (0,0) +(300:1.2 and 0.8) arc [start angle=300, end angle=330, x radius=1.2, y radius=0.8]; \draw[red ] (0 ,-0.66) to[bend left ] (0,-2); \draw[sky ] (0 , 0.66) to[bend left ] (0, 2); \draw[thin, red, dashed] (0 ,-0.66) to[bend right] (0,-2); \draw[thin, sky, dashed] (0 , 0.66) to[bend right] (0, 2); \fill ( 0.2,-1.25) circle (1pt); \fill (-0.2, 1.25) circle (1pt); \fill[violet] (0,0) +(120:1.2 and 0.8) circle (0.5pt); \fill[violet] (0,0) +(150:1.2 and 0.8) circle (0.5pt); \fill[violet] (0,0) +(300:1.2 and 0.8) circle (0.5pt); \fill[violet] (0,0) +(330:1.2 and 0.8) circle (0.5pt); \fill[blue] (0,0) +(030:2.4 and 1.6) circle (0.5pt); \fill[blue] (0,0) +(060:2.4 and 1.6) circle (0.5pt); \fill[blue] (0,0) +(210:2.4 and 1.6) circle (0.5pt); \fill[blue] (0,0) +(240:2.4 and 1.6) circle (0.5pt); \draw[black, thin] (0,0) +(030:2.4 and 1.6) circle (1pt); \draw[black, thin] (0,0) +(060:2.4 and 1.6) circle (1pt); \draw[black, thin] (0,0) +(210:2.4 and 1.6) circle (1pt); \draw[black, thin] (0,0) +(240:2.4 and 1.6) circle (1pt); \draw[violet] (0,0) +(120:1.2 and 0.8) circle (1pt); \draw[violet] (0,0) +(150:1.2 and 0.8) circle (1pt); \draw[violet] (0,0) +(300:1.2 and 0.8) circle (1pt); \draw[violet] (0,0) +(330:1.2 and 0.8) circle (1pt); \node at ( 1.75 , 1.25 ) {\(e_{1,1}\)}; \node at (-1.75 ,-1.25 ) {\(e_{1,2}\)}; \node at (-1.0625, 0.625) {\(e_{2,1}\)}; \node at ( 1.0625,-0.625) {\(e_{2,2}\)}; \end{tikzpicture} \caption{} \label{fig:hypermin} \end{figure} \end{document} My current result The picture I wish to draw:

I am trying to generate a quiz where I can generate a file answers.txt containing the id of each question, the x,y location on the page, the width,height and the answer. The macro side effects are brutal and I have no idea what is going on. The following minimal non-working example shows the error. I can try to save out the location of each one, but if I try to also print out width,height that give an error. \documentclass{article} \usepackage{xparse} \usepackage{tikz} \usepackage{zref-savepos}

I am a little bit confused with the new babel-german v3.0, where the naming convention has a breaking change: post-1996 convention is now the default one. Is it OK to still use ngerman in current documents? Would it be different with using the new german option? Should the replacement of ngerman be german or german-de/german-germany? The documentation suggests that "it is always advisable to use a more precise option such as german-de". Thus perhaps it should be safer and more stable to use german-de instead of german. For package authors passing/detecting language options, should there be any caution with this new change? (For example, shall one need to detect the version and apply different rules separately?) Thanks so much!

I am preparing a project that involves representing the Italian Parliament using a semicircle made of colored dots, as shown in the following image: I have tried to create something using the wheelchart package (page 19 of the manual), which allows generating similar charts. However, I am unable to automatically increase the number of dots per row. For example, in the figure there are 12 dots per row, but I would like a more customizable (for example 7 balls for every radius) and automatic solution to control this. I prefer big dots and not balls. \documentclass{article} \usepackage{tikz} \usepackage{wheelchart} \begin{document} \begin{tikzpicture} \pgfkeys{ /wheelchart, discrete, discrete pic={\shade[ball color=\WCvarB] (0,0) circle[radius=2pt];}, discrete sort=angle, discrete space at borders=false, start angle=180, total angle=180, value=\WCvarA } \wheelchart{ 120/blue/, 45/green/, 40/red/, 25/orange/, 10/purple/, 5/teal/ } \end{tikzpicture} \end{document}

There are various packages that will conveniently give extensible arrows with sub/superscripts. I'm aware of: amsmath (only for basic arrows) mathtools extarrows chemarrow You can of course do the same thing with TikZ or similar. I want something similar, but with no arrowheads at all. What's the best way to achieve that? I can do it with TikZ, but the mildly annoying part would be matching the standard arrow height and width. Should I figure out how to use the internal \arrowfill@ command in amsmath? My application is essentially marking a chain of edges connected in a graph, with various labels on the edges. Here's one attempt using a text em-dash. You can see that the em-dash isn't the same as the math-mode arrow. \documentclass[12pt]{amsart} \begin{document} \[ x \overset{\mathcal{U}}{\mathbin{\text{---}}} y \overset{\mathcal{U}}{\longrightarrow} z\] \end{document}

I am compiling a LaTeX document in VS Code using the LaTeX Workshop extension on Windows 11. My document uses: chemnum / chemstyle nomencl biblatex mhchem Originally my latexmk tool was configured with: -pdf However, this produced incorrect compound labels when using chemnum with a scheme environment (temporary labels such as TMP1, TMP2 were not replaced). Following advice from a previous question, I changed the compilation pipeline to: -pdfps, (see my previous question: VS Code LaTeX Workshop: how to configure settings.json when using both chemnum and nomencl?) This indeed fixes the chemnum labeling issue. However, now I cannot include PNG graphics. For example: \begin{figure} \centering \includegraphics[scale=0.8]{random.png} \caption{random} \label{fig:random} \end{figure} produces the error: Cannot determine size of graphic (no BoundingBox) (This also does not work with [width=0.5\textwidth] or when using a .pdf image instead of .png.). In the real document there are several PNG graphics. I would also like all PNG images to be included with a fixed scale=0.8. I found the following related question, but it is quite old, so perhaps there is a more up-to-date solution: Cannot determine size of graphic settings.json { "latex-workshop.latex.tools": [ { "name": "latexmk", "command": "latexmk", "args": [ "-synctex=1", "-interaction=nonstopmode", "-file-line-error", "-pdfps", "%DOC%" ] }, { "name": "makenomenclature", "command": "makeindex", "args": [ "%DOCFILE%.nlo", "-s", "nomencl.ist", "-o", "%DOCFILE%.nls" ] } ], "latex-workshop.latex.recipes": [ { "name": "latexmk → nomencl → latexmk", "tools": [ "latexmk", "makenomenclature", "latexmk" ] } ], "latex-workshop.latex.recipe.default": "latexmk → nomencl → latexmk", "latex-workshop.latex.autoBuild.run": "never", } aromatic-compounds.eps https://drive.google.com/file/d/1faCOOvd5xcVAF_KZqhx7vAI0Mqh7pmF6/view?usp=sharing main.tex \documentclass{article} \usepackage{geometry} \usepackage{graphicx} \usepackage[version=4]{mhchem} \usepackage{chemstyle} \usepackage{chemnum} \usepackage[backend=biber]{biblatex} \addbibresource{bib.bib} \usepackage{nomencl} \makenomenclature \begin{document} \nomenclature{A}{a} \printnomenclature \section{First} \cite{knuth1984texbook} \begin{scheme} \replacecmpd{benezen} \replacecmpd{toluene} \includegraphics[scale=0.8]{aromatic.eps} \caption{Aromatic-compounds} \label{aromatic-compounds} \end{scheme} \begin{figure} \centering \includegraphics[width=0.5\textwidth]{random.png} \caption{random} \label{fig:random} \end{figure} \refcmpd{benezen, toluene} \printbibliography \end{document} bib.bib @book{knuth1984texbook, title={The texbook}, author={Knuth, Donald Ervin and Bibby, Duane}, volume={15}, year={1984}, publisher={Addison-Wesley Reading} }

This question is a followup of a previous question of mine that David kindly answered with the following example: \documentclass{article} \usepackage{csquotes} \def\test#1{% \setbox0\hbox{#1}% \usebox{0}% \directlua{ local nn=0 for n in node.traverse_glyph(tex.box[0].head) do nn=n.char end if nn==8221 then tex.print("\string~yes") else tex.print("\string~no") end }} \begin{document} \begin{enumerate} \item \test{“Foo”} \item \test{\enquote{Bar}} \item \test{xyz} \end{enumerate} \ExplSyntaxOff \end{document} I'd like to expl3-ify this MCE and here is the first step which works nicely: \begin{filecontents*}[overwrite]{myfile.lua} function closing_double_quote(glyph) local nn=0 for n in node.traverse_glyph(glyph) do nn=n.char end if nn==8221 then tex.print("yes") else tex.print("~no") end end \end{filecontents*} \documentclass{article} \usepackage{csquotes} \ExplSyntaxOn \lua_now:n{ require('myfile') } \cs_new_protected:Nn \__mymodule_closing_double_quote:n { \setbox0\hbox{#1} \usebox{0} : \c_space_tl \lua_now:n{ tex.write(closing_double_quote(tex.box[0].head)) } } \begin{document} \begin{enumerate} \item \__mymodule_closing_double_quote:n {“Foo”} \item \__mymodule_closing_double_quote:n {\enquote{Bar}} \item \__mymodule_closing_double_quote:n {xyz} \end{enumerate} \end{document} What remains is: \setbox0\hbox{#1} \usebox{0} that could be expl3-ified as follows: \hbox_set:Nn \l_tmpa_box { #1 } \box_use:N \l_tmpa_box But what would be the equivalent of box[0] in the Lua code: tex.write(closing_double_quote(tex.box[0].head))

Is it possible to set the vertical space between two subtables as in Table 2 in the following MWE, but using something more "automatic" than setting a \vspace manually? \documentclass{book} \usepackage{subcaption} \subcaptionsetup[table]{position=top} \begin{document} \begin{table}[ht]\centering \caption{Table caption} \begin{subtable}{\linewidth}\centering \caption{First subtable caption} \begin{tabular}{cc} \hline a & b \\ c & d \\ \hline \end{tabular} \end{subtable} \begin{subtable}{\linewidth}\centering \caption{Second subtable caption} \begin{tabular}{cc} \hline e & f \\ g & h \\ \hline \end{tabular} \end{subtable} \end{table} \begin{table}[ht]\centering \caption{Table caption} \begin{subtable}{\linewidth}\centering \caption{First subtable caption} \begin{tabular}{cc} \hline a & b \\ c & d \\ \hline \end{tabular} \end{subtable}\vspace{10pt} \begin{subtable}{\linewidth}\centering \caption{Second subtable caption} \begin{tabular}{cc} \hline e & f \\ g & h \\ \hline \end{tabular} \end{subtable} \end{table} \end{document} Maybe this is a trivial question, but I found only the \vspace (or similar) answers.

I have an old latex file that in 2019 was perfectly ok. Today (in 2026) I try to compile the source and I get an error ERROR: Package tikz Error: Cannot parse this coordinate. The point in the file where it seems to be an error (according to emacs) is the following scope environment: \foreach\a in{(-30.5,4),(-13,9),(-16.5,-7.5),(34,0),(53,0),(72,0)} { \begin{scope}[shift={\a}] \draw (0,0) to[out=30, in=150] (4,0); \draw (-1,.5) to[out=-30, in=-150] (5,.5); \end{scope} } The weird thing is that file was completely fine and compiling some years ago! I isolated the problem creating a test file \documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \foreach\a in{(10,2), (5,-3)} { \begin{scope}[shift={\a}] \draw (0,0) to (2,2); \end{scope} } \end{tikzpicture} \end{document} and I get the same error. So, my question is What's wrong now, and how I can fix it in the current version of tikz?

My goal is to have zero-padded page numbers in the footer and in the table of contents. I use the code from this answer.

The MWE \DocumentMetadata{} \documentclass{article} \usepackage{mathtools} \mathtoolsset{mathic} \begin{document} \(a\) \end{document} gives the following error Runaway argument? \fi a\) \par \end {document} ! File ended while scanning use of \__math_grab_dollar_delim:w. <inserted text> \par <*> test.tex I suspect you have forgotten a `}', causing me to read past where you wanted me to stop.

I'm using the LaTeX package forest to render "surface grammar trees" of sentences. Using the particular grammar I'm using (Eisenberg), you can get trees where the leaves are not in natural order. E. g. the sentence "Ich suche verzweifelt einen Stift" ("I search desperately a pen") would have the adverb "verzweifelt" ("desperately") attached to the rest of the sentence at the very last layer and the syntactical analysis tree would look something like this: How is this possible in forest without having to put the adverb to the end of the sentence (which wouldn't make sense). This would produce the correct tree structure but with the wrong word order. How can I specifically move the "verzweifelt" node to the third word position without changing the tree structure? \documentclass{article} \usepackage{forest} \usetikzlibrary{calc} \usepackage[T1]{fontenc} \begin{document} \begin{forest} for tree={ grow=south, parent anchor=south, child anchor=north, align=center, l sep=15pt, s sep=10pt, edge path={ \noexpand\path [draw] (!u.south) -- +(0,-5pt) -| (.north)\forestoption{edge label}; }, } [$S_2$ [S [Ich, tier=word] [suche, tier=word] [PrGr [einen, tier=word] [Stift, tier=word] ] ] [verzweifelt, tier=word] ] \end{forest} \end{document}

I want to colour the harakat (diacritics) of a text in Pashto. I use Luatex, and I want to switch this function on and off.

What might be the problem, or is there an easy option in Luatex?

I am designing a square (or “squarish” actually) map protractor in TikZ. So far, I have managed to draw the degree ticks along the four sides by clipping radial lines between two closed paths using the even odd rule like I saw in this answer. The ticks are generated in a \foreach loop. To avoid drawing long ticks on top of short ones, I separated them into two loops using a conditional test. I am not sure whether this separation is actually necessary for correct SVG export/printing, but that is how I implemented it. Below is a MWE: \documentclass[tikz]{standalone} %,convert={outfile=\main.svg} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usetikzlibrary{intersections, pgfplots.fillbetween} \pgfdeclarelayer{pre main} \pgfdeclarelayer{main} \pgfsetlayers{pre main, main} \usetikzlibrary{shapes} \begin{document} %all of this is needed to easily clip between two closed paths using even odd rule \makeatletter \def\@appendnamedsoftpath#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\expandafter\expandafter\def\expandafter\expandafter\expandafter\@temppatha\expandafter\expandafter\expandafter{\expandafter\@temppatha\@temppathb}% \pgfsyssoftpath@setcurrentpath\@temppatha } \def\@appendnamedpathforactions#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\def\expandafter\@temppatha\expandafter{\csname @temppatha\expandafter\endcsname\@temppathb}% \let\tikz@actions@path\@temppatha } \tikzset{ use path for main/.code={% \tikz@addmode{% \expandafter\pgfsyssoftpath@setcurrentpath\csname tikz@intersect@path@name@#1\endcsname }% }, append path for main/.code={% \tikz@addmode{% \@appendnamedsoftpath{#1}% }% }, use path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions\expandafter\let\expandafter\tikz@actions@path\csname tikz@intersect@path@name@#1\endcsname}% }, append path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions \@appendnamedpathforactions{#1}}% }, use path/.style={% use path for main=#1, use path for actions=#1, }, append path/.style={% append path for main=#1, append path for actions=#1 } } \makeatother \begin{tikzpicture} \pgfmathsetmacro\bigside{7} \pgfmathsetmacro\smallsidedelta{0.5} %cuts \draw[rounded corners=12pt, name path=outside] (0,0) rectangle (\bigside,\bigside); \draw[dotted, rounded corners=12pt, name path=inside] (\smallsidedelta,\smallsidedelta) rectangle (\bigside-\smallsidedelta,\bigside-\smallsidedelta); %remove before cutting or printign.

When numbers get big, they don't have enough space to fit unless the labels become too small to read (actual printing size of the protractor will be something like 7x7 or 8x8cm). So they need to be shifted in such a way that they fit. 355 in the provided image is a clear example of what I mean. I can consider shifting them radially as well, but they need to stay to the outside of the dotted line, which I can make a little smaller. I really don't know where to start and didn't manage to find anything online. Thank you for your time!

The question arised from the previous link and the luadraw solution. I am using luadraw to visualize the surface z = x^2 + y^2 together with the intersection curve corresponding to the direction u = (1,0). I would like to know whether it is possible to: Label the coordinate axes $x$, $y$, and $z$, Label the point $c = (0,0)$, Indicate the direction $u = (1,0)$, And label the function $F(t) = t^2$ corresponding to the intersection curve. When I try to use Dtext3d, the document compiles but the output appears blank in Overleaf. Is there a reliable way to add these labels when using luadraw? \documentclass[border=5pt]{standalone} \usepackage[svgnames]{xcolor} \usepackage[3d]{luadraw} \usepackage{fourier-otf} \usepackage{tikz} \begin{document} \begin{luadraw}{name=paraboloid} local g = graph3d:new{ window3d = {-2,2,-2,2,0,8}, window = {-4.5,4,-3,9.5}, size = {10,10,0}, viewdir = perspective("central",30,50,20) } -- Surface local S = cartesian3d(function(x,y) return x^2+y^2 end, 2,-2,-2,2) -- Direction local c = Origin local u = M(1,0,0) local N = pt3d.prod(u, vecK) -- Intersection curve local Curve = g:Intersection3d(S, {c,N}) -- Draw surface g:Dfacet(S, {usepalette={palGasFlame,"z"}, edgecolor="gray", clip=true}) -- Draw curve g:Dedges(Curve, {hidden=true, color="Navy", width=12}) -- Axes g:Dline3d({Origin, M(2,0,0)}, {color="black", width=1, dash="dotted"}) g:Dline3d({Origin, M(0,2,0)}, {color="black", width=1, dash="dotted"}) g:Dline3d({Origin, M(0,0,6)}, {color="black", width=1, dash="dotted"}) g:Show() \end{luadraw} % ---- 2D overlay labels (safe in Overleaf) ---- \begin{tikzpicture}[overlay] \node at (3.7,4.2) {$x$}; \node at (1.1,4.8) {$y$}; \node at (2.5,7.3) {$z$}; \end{tikzpicture} \end{document}

In §331 of tex.web we have this: first:=1; ... if not init_terminal then goto final_end; first:=last+1; {|init_terminal| has set |loc| and |last|} So, before input_ln, which is called by init_terminal, we have: loc is 0, first is 1, last is 0. Let's type x<return> in response to **. Then after init_terminal we will have: loc is 1, first is 1, last is 2. And then (due to above snippet) first will be 3. This means that first line of input is permanently kept in buffer array throughout the entire TeX job. And so the length of the first line will restrict the length of line that TeX can read. In particular, one and the same file will compile cleanly if file name is relative, and will fail to compile if file name is absolute. Why first line of input is kept in buffer array?

A MWS is as follows. \documentclass{exam-zh} \makeatletter \DeclareSymbolFont{AMSa}{U}{msa}{m}{n} %\DeclareSymbolFont{AMSb}{U}{msb}{m}{n} \DeclareMathSymbol{\therefore}{\mathrel}{AMSa}{"29} \DeclareMathSymbol{\because}{\mathrel}{AMSa}{"2A} \makeatother \begin{document} $\because ABCD=\therefore ABCD$ \end{document} As you see, the sizes of \because and \therefore in exam-zh are very small although I invoke them from amssymb. How to fix this to make the sizes of them be normal when invoking them from amssymb?

\documentclass{article} \usepackage[font=small, labelfont=bf, format=hang]{caption} \usepackage{tabularray} \usepackage{tblr-extras} \UseTblrLibrary{amsmath, booktabs, caption} \begin{document} \begin{table}[h] \centering \begin{talltblr}[caption={A talltblr table.}]{colspec={cc}} \toprule a & b\\ \midrule x & y\\ \bottomrule \end{talltblr} \end{table} \end{document} Using the code above, I get the following result for my talltblr (i.e. the caption width is limited to the table width). I tried the approach from here: \documentclass{article} \usepackage[font=small, labelfont=bf, format=hang]{caption} \usepackage{tabularray} \usepackage{tblr-extras} \UseTblrLibrary{amsmath, booktabs, caption} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \DefTblrTemplate{firsthead}{caption}{% \makebox[\tablewidth]{\parbox{\columnwidth}{% \UseTblrTemplate{caption}{normal}% }}% } \SetTblrTemplate{firsthead}{caption} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \begin{document} \begin{table}[h] \centering \caption{A regular table. A regular table. A regular table. A regular table. A regular table. A regular table. A regular table. A regular table. A regular table.} \begin{tabular}{cc} \toprule a & b\\ \midrule x & y\\ \bottomrule \end{tabular} \end{table} \begin{table}[h] \centering \caption{A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table.} \begin{tblr} { colspec={cc} } \toprule a & b\\ \midrule x & y\\ \bottomrule \end{tblr} \end{table} \begin{table}[h] \centering \begin{talltblr} [ caption={A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table.} ] { colspec={cc} } \toprule a & b\\ \midrule x & y\\ \bottomrule \end{talltblr} \end{table} \end{document} Now the caption has the right width, but it is too close to the table itself. Also, the caption font is too big and the label is not bold, which I can fix / hack if I add \SetTblrStyle{caption-tag}{font=\small\bfseries} \SetTblrStyle{caption-text}{font=\small} but I'm not sure if this is the way to go (and it does not fix the issue of the caption touching the table). I also tried to have a look at the default caption definitions myself in the source code but I just don't understand even remotely enough of LaTeX3). Edit for clarity: I don't need to be able to control table, talltblr, and tblr with \captionsetup, I am rather looking for a way to get the same consistent captions for figure, table, tblr and talltblr environments in my document. I realise this is not easy, especially since the different caption style for talltblr is apparently a feature: I don't think it is a bug. In many aspects, tabularray is different from traditional tables https://github.com/TeXackers/tabularray/issues/255#issuecomment-1142833319)
