This isn't a question of 'how to fix it?' Just 'what's going on?'

I'm attempting to make a table of logical quantum gates in latex and I previously had a problem with the matrices overlapping with \raisebox so i used \vcenter{\hbox{...}} yet whenever I increase spacing the space between the rows in each matrix expands. \[ \renewcommand{\arraystretch}{2.2} \begin{array}{|l@{\hskip 1.5cm}c@{\hskip 1.5cm}c|} \hline \textbf{Operator} & \textbf{Gate(s)} & \textbf{Matrix} \\ \hline \text{Pauli-X (X)} & \Qcircuit @C=1em @R=.7em { & \gate{X} & \qw } & \vcenter{\hbox{$\begin{bmatrix} 0 & 1 \\ 1 & 0 \end{bmatrix}$}} \\ \text{Pauli-Y (Y)} & \Qcircuit @C=1em @R=.7em { & \gate{Y} & \qw } & \vcenter{\hbox{$\begin{bmatrix} 0 & -i \\ i & 0 \end{bmatrix}$}} \\ \text{Pauli-Z (Z)} & \Qcircuit @C=1em @R=.7em { & \gate{Z} & \qw } & \vcenter{\hbox{$\begin{bmatrix} 1 & 0 \\ 0 & -1 \end{bmatrix}$}} \\ \text{Hadamard (H)} & \Qcircuit @C=1em @R=.7em { & \gate{H} & \qw } & \vcenter{\hbox{$\dfrac{1}{\sqrt{2}} \begin{bmatrix} 1 & 1 \\ 1 & -1 \end{bmatrix}$}} \\ \hline \end{array} \] For reference this is what it looks like at 3.2 spacing:

The scontents package provides an internal verbatim environment verbatimsc used by the \typestored command which works in the same way as the verbatim environment and can be customized using the fancyhdr, listings and minted packages. Unfortunately none of these options provide (yet) support for tagged pdf. If I use this code: \DocumentMetadata{lang = en-US,pdfversion = 2.0,pdfstandard = ua-2,testphase =latest} \documentclass{article} \usepackage{unicode-math} \usepackage{scontents} \begin{document} % environment \begin{scontents}[print-env=true] First code \verb|\foo| \end{scontents} % \typestored \typestored[1]{contents} \end{document} I get the following error: Package tagpdf Info: luamml has been enabled and will create an MathML file. Runaway argument? ! File ended while scanning use of \__scontents_xverb:w. <inserted text> \par l.12 \typestored[1]{contents} My first attempt is to undefine verbatimsc and use \UseInstance{blockenv} to redefine it. Here's the MWE: \DocumentMetadata{lang = en-US,pdfversion = 2.0,pdfstandard = ua-2,testphase =latest} \documentclass{article} \usepackage{unicode-math} \usepackage{scontents} \ExplSyntaxOn \cs_undefine:N \verbatimsc \cs_undefine:N \endverbatimsc \DeclareInstance{blockenv}{verbatiminternal}{display} { env-name = verbatiminternal, tag-name = verbatim, tag-class = , tagging-recipe = standard, inner-level-counter = , level-increase = false, setup-code = , block-instance = displayblock , inner-instance = , para-flattened = true } \NewDocumentEnvironment {verbatimsc} { } { \UseInstance{blockenv}{verbatiminternal} }{ \endblockenv } \ExplSyntaxOff \begin{document} % environment \begin{scontents}[print-env=true] First code \verb|\foo| \end{scontents} % \typestored \typestored[1]{contents} \end{document} But it returns the following error: Package tagpdf Info: luamml has been enabled and will create an MathML file. Runaway argument? ! File ended while scanning use of \template code > blockenv/display. <inserted text> \par l.33 \typestored[1]{contents} I'm using the updated TL2025 and lualatex-dev, but I'm a bit lost here. I read in a related post Tagged PDF & verbatim with line breaks that it's good to provide direct support for this, so my idea is to document how to make \typestored work with tagged pdf or implement it with some conditionals.

I want to create something like Theorem 1, Theorem 2, Lemma 3, etc but instead of theorem and lemma, it is something else, maybe like Algorithm 1, Algorithm 2, etc. I tried changing the word theorem into algorithm, for example changing the following \documentclass{article} \usepackage{enumitem} \usepackage{amsthm} \usepackage{amssymb} \usepackage{amsmath} \newtheorem{theorem}{Theorem}[section] \newtheorem{corollary}{Corollary}[theorem] \newtheorem{lemma}[theorem]{Lemma} \theoremstyle{remark} \newtheorem*{remark}{Remark} \theoremstyle{definition} \newtheorem{definition}{Definition}[section] \begin{document} \begin{theorem} content... \end{theorem} \end{document} into \documentclass{article} \usepackage{enumitem} \usepackage{amsthm} \usepackage{amssymb} \usepackage{amsmath} \newtheorem{theorem}{Theorem}[section] \newtheorem{corollary}{Corollary}[theorem] \newtheorem{lemma}[theorem]{Lemma} \theoremstyle{remark} \newtheorem*{remark}{Remark} \theoremstyle{definition} \newtheorem{definition}{Definition}[section] \begin{document} \begin{algorithm} content... \end{algorithm} \end{document} will throw Environment algorithm undefined error (sorry I'm new at LaTeX, I don't know how it works, i was just copy pasting code). So how do I do it?

How to get the same result with tex.toks[3] = "\\texbf{Texte en gras}" \documentclass{article} \begin{document} \directlua{ tex.toks[3] = "Texte en gras" } \textbf{\the\toks3} \end{document}

I recently noticed that in physics gluons are usually typeset with (what I believe is called) a single-story g. The default g that comes with STIX Two Math – the math font I am using – is the double-story g and I would like to keep it that way for any variables called "g" that are not representing a gluon. My idea was to store it in a command similar to how \ell creates a script version of the letter "l" for quick access. STIX Two Math has a single-story g when applying stylistic set ss02. How could I load this g and store it in a command? A minimal example to work with should be: \documentclass{scrartcl} \usepackage{fontspec} \usepackage{mathtools} \usepackage{unicode-math} \setmainfont{STIX Two Text} \setmathfont{STIX Two Math} \begin{document} \[g\] \end{document}

@markus-kuhn offered an excellent answer to restoring parskip spacing in minipages in this thread with: \usepackage{parskip} \setlength{\parskip}{\medskipamount} \newcommand{\@minipagerestore}{\setlength{\parskip}{\medskipamount}} Can the same be done for tables? The only solution that I can see is using \medskip\par, which is great, but not an automatic solution (which is what I am looking for). I'd also ideally like to keep using column type X or equivalent. MWE: \documentclass{article} \usepackage{tabularray} \begin{document} \begin{center} \begin{tblr}{ colspec={| X | X |}, hlines, row{1}={halign=c} } Current Output & Expected Output \\ Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text.

When I convert latex generated pdfs to svg using inkscape, the svg has serifs, where the original pdf does not. Take thic code, for example: \documentclass{article} \usepackage{graphicx} \newcommand{\breite}{50cm} \usepackage[margin=50mm,paperheight=\breite,paperwidth=\breite]{geometry} \parindent0mm \begin{document} \resizebox{30cm}{!}{\sf\textbf{K}} \end{document} The pdf displays an SF K But inkscape test.pdf -o test.svg delivers a K with serifs. How can I preserve the \sf property during file format convertions with inkscape? Thank you in advance!

I am going through the pdfTeX manual and after unravelling the usage of \pdfstartlink, I see that the following is a possible usage: \pdfstartlink goto named <general text> <general text> (Specifically, \pdfstartlink goto <page spec> <general text> is valid usage, and <page spec> may refer to either page <number or named <general text>) Now, I see no reference to this usage in the manual itself. The only thing the manual says about specifying <page spec> after \pdfstartlink is "The <page spec> alternative specifies a page number for the destination. In this case, the zoom factor is given by <general text>" I'm guessing that <page spec>'s <general text> is a name that is a reference to a page (the name I assume would be in the Pages subdictionary of the document catalog's Names entry). But the pdfTeX manual doesn't seem to mention any references for naming pages. I'd greatly appreciate it if someone could shed some light on what exactly this option does, and how to use it. Thank you!

I am making arrays of numbers. How can I align them automatically by the ones digit? I understand that this won't work for arrays with math expressions in them, but I think it would be more legible for arrays which contain only decimal numbers. \documentclass{article} \begin{document} I want to align the numbers in the following array by the 1's digit, which I can't deem to accomplish using column specifiers. \[ \begin{array}{rr} -1 & 12.009 \\ 98 & -98 \end{array} \] like this, but without the phantoms: \[ \begin{array}{rr} -1 & 12.009 \\ 98 & -98\phantom{.009} \end{array} \] \end{document}

When I teach the Baire category theorem, I write on the board the following diagram: I would like to have a TeX version of this diagram. The easiest possible solution would be with arrays, but then I can’t get the long underbraces and diagonal $\in$ symbols. Maybe this requires tikz? EDIT: this is what I managed to cook up with the help of some online tools and a lot of fiddling around.

Predefined TikZ patterns have always worked quite well for me, with one exception: I could never figure out how to set a specific "scale" or "zoom factor", so to say. Currently, I am creating graphs with shapes that span over the better part of an A4 page's width, hence in some cases, the provided patterns like north west lines are visually too dense. The following straightforward sketch visualizes what I would like to achieve, ideally without needing to create a pattern from scratch: MWE: \documentclass[margin=5mm]{standalone} \usepackage{tikz} \usetikzlibrary{shapes,patterns} \begin{document} \begin{tikzpicture} \draw[pattern=north east lines] (0,0) rectangle ++(4,4); \end{tikzpicture} \end{document}

I would like to be able to use commands with default arguments in captions of figures/tables without causing an error in \listoftables or \listoffigures. For example, the following code causes an error stating "Undefined control sequence.": \documentclass{article} \begin{document} \listoftables \newcommand{\acommand}[1][X]{b(#1)} \begin{table} \caption{I'm using a command $\acommand$ in a caption.} \end{table} I'm using the command again $\acommand[Y]$. \end{document} This code does not generate any errors if the optional argument is removed from the definition of \acommand (and any calls). Things like \protect and supplying the argument doesn't make any difference. Anyone know how to avoid this error? Edit: Sorry I forgot to mention that the definition of \acommand is deliberately placed after the call to \listoftables. In reality I'm managing a very large document made of many subdocuments and to keep things organised, its extremely helpful to have my commands defined in the relevant subdocuments/subsections instead of defining everything before the \listoftables which must appear near the start of the document. This works for any commands that don't have optional arguments. You can test this by removing the optional argument in the MWE above and see that the error disappears. I'm hoping there is a way that I can remove the error while retaining optional arguments.

I am creating a handout that includes some trees created using tikz-qtree, and I'm having two inter-related issues: one of unnecessary white space and one where a potential solution behaves unexpectedly. Sometimes, a tree ends up moved to the next page even though there's enough space for it to fit, leaving a lot of white space unnecessarily. I can force the tree to fill that space with something like \vspace{-6em}, but I don't understand why it works like it does. First, if you only do -1em for example, up to 5, nothing changes, and then with -6em, the tree does move to the previous page to fill the white space BUT too high, overlapping the text, like this (notice the "1" at the bottom where the page ends): I understand that as you move something up it will eventually overlap text above where it would have been. What I don't understand is why 1 more em is just enough to move the tree even though the space under the tree, once it moves, is clearly much more then 1em. In summary, (A) why does the tree move to the next page when there is enough space for it and (B) why does \vspace not work until some tipping point, overlapping the text? MWE (BUT recall that you need to adjust \vspace{-2em}to see what happens with the tree) \documentclass{article} \usepackage{tikz} \usepackage{tikz-qtree} \usepackage{tikz-qtree-compat} \usepackage{amsmath} \usepackage{amssymb} \begin{document} \section{Some heading} \begin{itemize} \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \item Some text to fill this page. \end{itemize} \section{Another heading} \begin{itemize} \item Some text. \vspace{-2em} \end{itemize} \begin{tikzpicture}[baseline]\tikzset{every tree node/.style={align=center,anchor=north}} \Tree [.CP \phantom{Test} [.C' \node(C){C\\$\varnothing$}; [.TP [.\node(SpecTP){DP}; ] [.T' \node(T){T}; [.VoiceP \phantom{Test} [.Voice' \node(Voice){Voice\\t_{\text{pass}}}; [.VP [.V' \node(V){V}; \node(Object){t_{\text{DP}}}; ] ] ] ] ] ] ] ] \draw[->] (Voice) to[out=240,in=240,looseness=1.9] (T); \draw[->] (Object) to[out=240,in=200,looseness=1.2] (SpecTP); \end{tikzpicture} \end{document}

I'm using tipauni package to write IPA symbols, but there is a problem with the accent marker. I wanted to write /aˈʧitə/, but as you can see in the following image, the ' just goes above the a. Tipa doesn't give me this problem, but if possible I'd want to use tipauni. Another example: the first one is right, the second is not (I guess the ' can only go above "short" letters"): I'm using LuaLaTex, but the problem is the same with XeLaTex too. MWE to reproduce the output of the first image (run with LuaLaTeX): \documentclass{article} \usepackage{tipauni} \begin{document} \textipa{/aˈʧitə/} \end{document}

With the new tagging possibilities a "figure" should reside within a figure tag. To my understanding all the figure environments are float environments. Nevertheless I need to display a figure in the same text flow as it "set" - so basically I need to place the figure Here. There have been several threads with the discussion how to solve the this topic - without tagging enabled. One of the most common is to use the package float with the option H. A very simplistic MWE (for demonstration purpose only) \DocumentMetadata{ pdfstandard = ua-2, pdfversion = 2.0, testphase = latest, lang=de, } \documentclass{article} \usepackage[showframe]{geometry} \usepackage{float} \usepackage{xcolor, kantlipsum} \begin{document} \kant[4-6] \begin{figure}[H] \framebox[\textwidth]{ \begin{minipage}{0.9\textwidth} \kant[64] \end{minipage} } \caption{quick caption} \end{figure} \underline{\color{red} Some text inbetween} \kant[64-67] \end{document} The red underlined text should appear below the figure. As mentioned on the compatibility site float is incompatible with the option [H]. When I compile the above code I get Package tagpdf Warning: Parent-Child 'Document/pdf2' --> 'Caption/pdf2'. (tagpdf) Relation is not allowed (struct 2, /Document --> (tagpdf) struct 15) on line 21 because the caption is not properly tagged. I've read different solutions but remain unclear if they work generally. At least for this scenario [h!] won't help. How to force a figure to be placed "Here" and have a valid tagged PDF?

I used to have many commands programmed to insert a space at the very beginning, except if the starred version is used instead. I have since then automatized the space insertion by using a smart \coolspace command that only inserts a space when there is something before. This smart command works in most cases, except in the specific situation where we are inside a list AND within an argument (such as one of \textbf{} -- see MWE). Is there a solution to improve the command, i.e. make it NOT insert a space in this case? MWE \documentclass{article} \usepackage{enumitem} \DeclareRobustCommand{\coolspace}{% \ifhmode \ifnum\lastnodetype=1 \else \unskip\space% \fi% \fi} \parindent0ex \begin{document} This\coolspace correctly produces a space between \textit{this} and \textit{correctly}. \coolspace No space at the beginning of a line, good. \textbf{\coolspace Even if it's part of the content of an argument.} \begin{itemize}[label=--] \item This\coolspace correctly produces a space between \textit{this} and \textit{correctly} \item\coolspace No space at the beginning of a line, good. \item\textbf{\coolspace It's an argument, a space is incorrectly produced.} \end{itemize} \end{document}

I'm working on some school notes, but my skills aren't enough to create something similar to the image. It's something much more clumsy. I'm sure that with TikZ something very similar can be done.

I have created a custom environment wherein the first page on which the environment starts should have a modified top margin, for example to insert a picture (see gray rectangle).

I've been playing around with pdfTeX primitives lately, and I'm trying to insert an inline image (of a smiley).

But an image does show up if you use SumatraPDF (or most other viewers I assume, Acrobat is the only one which doesn't seem to show the image). Though if you run ghostscript (gs -dDEBUG file.pdf > log.txt) I noticed that nothing is printed after ID, which I assume is the issue. Another thing, if you surround the inline image with q...Q, Acrobat preflight complains about unbalanced q...Qs (too many qs). Looking at this with ghostscript, I see the following: q 0.996264 0 0 0.996264 0 0 cm 100 0 0 100 0 0 cm BI /BPC 8 /CS /DeviceRGB /F [ /AHx ] /W 9 /H 9 ID Q So (a) none of the image data is printed after ID, and (b) the Q is placed after the ID, where the image data should be. So I assume it's being read as the image data and that's why there's unbalanced q/Qs? Finally, if you remove \nopagenumbers, Acrobat preflight reports "invalid operator(s)" for the cm operator, which I was able to determine is the cm operator after the image, which places translates the CTM to place the page number. I have consulted the PDF standard, and I am unsure why this is happening. Any help would be greatly appreciated, thank you!

When should I use \text_uppercase:n and when should I use \MakeUppercase? I assumed that \text_uppercase:n would always be more reliable, but I found it fails to deal with \today when a babel language is loaded in a modern way. Whereas \MakeUppercase succeeds in such a case. Consider the following MWE: \documentclass{article} \usepackage[australian, provide*=*]{babel} % \usepackage[australian]{babel} % ← works \begin{document} \MakeUppercase \today \ExplSyntaxOn \text_uppercase:n \today \end{document}

Consider the following MWE: \documentclass{article} \usepackage{amsmath} \usepackage{siunitx} \ExplSyntaxOn \NewDocumentCommand{\evalfunction}{O{} O{10} m } { \num[#1]{\fp_eval:n { trunc((sqrt(#3+4)-2)/#3,#2) }} %https://tex.stackexchange.com/a/197854/10898 } \ExplSyntaxOff \begin{document} \begin{center} \renewcommand{\arraystretch}{1.2} \begin{tabular}{|r|c|} \hline $x$ & $f(x)$ \\ \hline $0.1$ & \evalfunction{0.1} \\ $0.01$ & \evalfunction{0.01} \\ $0.001$ & \evalfunction{0.001} \\ $0.0001$ & \evalfunction{0.0001} \\ \hline \end{tabular} \end{center} \end{document} The desired output is as expected. I am seeking to create a generic way of calling a function locally instead of defining within a command. Note that the command \evalfunction only works for (sqrt(#3+4)-2)/#3. I would like this to be customizable. Something like \evalfunctiondefn[abc]{(sqrt(#3+4)-2)/#3} then call \evalfunction[abc]{0.1}. Also note \evalfunction{0.01} only shows 9 decimal places instead of 10.

I want to set metadata for Tagged PDFs but somehow this fails. I tried to narrow down the source of this issue and excluded all packages. Therefore I follow the example from Ulrike \DocumentMetadata{ lang=en, % testphase=latest, % pdfstandard=UA-2, } \documentclass{article} \ExplSyntaxOn \pdfmanagement_add:nnn{Info}{Title}{(My~other~Story)} \pdfmanagement_add:nnn{Info}{Author}{(Someone)} \ExplSyntaxOff \begin{document} aaa1 \end{document} It seems like as soon as the ua-2 is enabled the metatags are gone. pdfinfo clearly writes Custom Metadata: no Following Wiki I couldn't see a reason why MetaTags are not allowed. Is there a way to set the attributes? NOTE: Since its a MWE I focused on two attributes only. For real life I need additional attributes. Running on lualatex 1.22.0
