In this MWE, how can I replace the outside framebox by ordinary xy axis? \documentclass{article} \usepackage{luamplib} \begin{document} \begin{mplibcode} input graph beginfig(0); draw begingraph(4cm,5cm); setrange(-1,0,2,4); gdraw (-1,1) for x=-0.9 step 0.1 until 2: ..

However, if the commented-out line \setmathfont{TeX Gyre Termes Math...[...range=...] is uncommented then I get an arithmetic overflow when the qed-like diamond symbol is to appear. But why is the diamond symbol being selected from TeX Gyre Termes Math now, when apparently it was not before?

For a book project we're experimenting with configuring glossary. In our case we'd like to use xltabular. But sometimes the term in the first column is a bit wide, in that case we'd like to use \multicolumn and typeset the description on the row below. The naïve approch of course does not work (MWE below). Since we're using this for glossary entrys we can only use a single macro. Anyone have a good approach on how to do this? I'm assuming it is down to what is "allowed" at the start of a table row. Edit, version 2: This at least gets around the incomplete \ifdim error. But if we use the \multicolumn line, we instead get a Misplaced \omit. \multispan ->\omit \@multispan l.31 \Foo{AAAAAAAAAAAAAAAAAA}{BBB} error. One can get around this by starting the entry by \tabularnewline, but then we have an extra blank linie, that we'd need to back track \documentclass[a4paper]{article} \usepackage{array,booktabs} \begin{document} \makeatletter % if #1 is too long, typeset it in \multicolumn, and move description % to next line \NewDocumentCommand\Foo{mm}{ \settowidth\@tempdima{#1} \ifdim\@tempdima> 0.2\textwidth\relax \FooLong{#1}{#2} \else \FooShort{#1}{#2} \fi } \NewDocumentCommand\FooLong{mm}{ % \multicolumn{2}{l}{#1} #1 \tabularnewline & #2 \tabularnewline } \NewDocumentCommand\FooShort{mm}{ #1 & #2 \tabularnewline } \makeatother \noindent \begin{tabular}{@{}l l@{}} \Foo{AAA}{BBB} \Foo{AAAAAAAAAAAAAAAAAA}{BBB} \end{tabular} \end{document} Version 1: \documentclass[a4paper]{article} \usepackage{xltabular} \begin{document} \makeatletter % if #1 is too long, typeset it in \multicolumn, and move description % to next line \NewDocumentCommand\Foo{mm}{ \settowidth\@tempdima{#1} \ifdim\@tempdima> 0.2\textwidth\relax \multicolumn{2}{l}{#1} \tabularnewline & #2 \tabularnewline \else #1 & #2 \tabularnewline \fi } \makeatother \noindent \begin{xltabular}{\textwidth}{@{}l X@{}} \Foo{AAA}{BBB} \Foo{AAAAAAAAAAAAAAAAAA}{BBB} \end{xltabular} \end{document}

I know that there is allowframebreaks and framebreak and I have read a manual (of beamer?) that suggests to avoid using them. Nevertheless, when preparing course notes sometimes I need to split to several slides of similar content. I am asking if it is possible to do automatically the numbering 1/n, 2/n, 3/, etc. As an example: \documentclass[10pt]{beamer} \usetheme{moloch} \usepackage{babel} \title{Algèbre linéaire} \author{DA} \date{} \begin{document} \maketitle \section{Introduction} %-------------------------------------- \begin{frame}{De la structure à la représentation (1/3)} \begin{block}{Objets essentiels} \begin{itemize} \item \ldots \end{itemize} \end{block} \end{frame} %-------------------------------------- \begin{frame}{De la structure à la représentation (2/3)} \begin{block}{Concepts clés} \begin{itemize} \item \ldots \end{itemize} \end{block} \end{frame} %-------------------------------------- \begin{frame}{De la structure à la représentation (3/3)} \begin{alertblock}{Idée centrale : diagonalisation} blabla \end{alertblock} \end{frame} \end{document}

How can I crop an image and then keep its aspect ratio automatically resized and keep its resolution the same as what it originally us ? Basically I want to like zoom in on an image. For example, I want to zoom in such that the A fills the top and bottom of the image. Here is a MWE but you dont have to stick to it. I dont know what I am doing at all. \documentclass[twocolumn]{article} \usepackage{graphicx} \usepackage{subcaption} % <-- correct package \usepackage{booktabs} \usepackage[colorlinks]{hyperref} \usepackage{nicematrix} \usepackage[export]{adjustbox} % <-- provides \adjincludegraphics and cropping+scaling tools [1](https://tex.stackexchange.com/questions/57418/crop-an-inserted-image)[2](https://ctan.org/pkg/adjustbox) \begin{document} % ---- Tight frame: no padding between border and content ---- \setlength{\fboxsep}{0pt} \setlength{\fboxrule}{0.4pt} % ---- Cell geometry (ONE truth for all subfigures) ---- \newlength{\cellw} \newlength{\cellh} \setlength{\cellw}{0.23\textwidth} \setlength{\cellh}{0.17\textwidth} % choose the height you want (tweak once, applies everywhere) % ---- Image cell: crop (trim+clip) THEN scale to EXACT cell size ---- % The key trick is using BOTH width and height; adjustbox handles the crop+resize pipeline.

It fails. If the dimensions on paper is 1337x137, then after zooming in via cropping it must still be 1337x137. I dont know how else to say it other than i just want to zoom in on an image. EDIT: Crop certain percent from each side of the figure not the same because cropping a % from 1 side distorts the human in the figure above. I need to crop with correct set of numbers. Alternatively, is there a [zoom] function that I can use ?

I want the following simple layout with enumitem: Blah blah noindent I. Foo II. Bar blah blah long line paragraph wrapping continues here III. Baz Blah blah noindent non-enumerate text Labels are right aligned, \labelsep can be fixed (e.g. 0.5em), and text continues from the same horizonal position on the next line in the case of a longer paragraph (I think this means \itemsep should be zero). enumitem apparently has the capacity to calculate the width of the widest label and set \labelwidth accordingly, though I can't determine under what circumstances that happens after reading the documentation. I can set widest=<whatever> to achieve the output I want, but I'd like to know if I can achieve the same by setting one or more parameters to ! or *, i.e. computing the parameters automatically. MWE and output are below, basically I just want the widest label (maybe VI or III or IV) label to be left-aligned with the left edge of the VVVVV (the left edge of the text area), everything else the same. \documentclass{article} \usepackage{enumitem} \begin{document} \begin{enumerate}[label=\Roman*.,nosep,align=right, leftmargin=*, labelindent=0pt, labelsep=0.5em, itemsep=0pt, % widest=VI, % I don't want to use this! ] \item Alpha. \item Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

I am trying to generate PDF/UA-2 compliant PDFs, and so far most of what I tried works with the last updates to the tagging support (thanks!). But with this file: \DocumentMetadata{lang=en,tagging=on,pdfstandard={UA-2}} \documentclass{article} \usepackage{newtxmath} \title{.} \begin{document} \maketitle \[\Bigg|\] \end{document} compiled with LuaLaTeX, verapdf tells me that the produced PDF is not valid because of a font issue, namely: The glyph can not be mapped to Unicode The Font dictionary of all fonts shall define the map of all used character codes to Unicode values, either via a ToUnicode entry, or other mechanisms as defined in ISO 14289-2, 8.4.5.8 I am assuming "the glyph" is the stretched vertical bar, and that the issue is with missing info from the math font loaded by newtxmath. What can I do, given that I would really like to keep newtxmath? Teach LuaLaTeX about the Unicode equivalent to that glyph (and others)? Use stretchable characters from another font? (but how?) Put the info in the font? (but how?)

Using "sloped" I know how to write text parallel to a line, but how do I make the text also at an angle in the second case? \documentclass{article} \usepackage{tikz} \usetikzlibrary{positioning,matrix,calc} \begin{document} \begin{tikzpicture} \draw [red,ultra thick] (0,0)coordinate(A1)-- (3,5)coordinate(A2); \path (A1) -- (A2) node[sloped,pos=0.3,draw,fill=white]{aa}; \draw [blue,ultra thick] (1,0)coordinate(A3)-- (4,5)coordinate(A4); \foreach \i in {1,...,5} \node [sloped,draw,fill=white] at ($(A3)!{\i*10mm}!(A4)$) {\i}; \end{tikzpicture} \end{document} To be clear, the nodes must have a set distance between them.

I am trying, for the purposes of a reusable library, to create dynamic class names in tabularray. Here is my minimal code: \documentclass{article} \usepackage{tabularray} \usepackage{xcolor} \date{} \newcounter{stylectr} \setcounter{stylectr}{1} % compiles, but non-dynamic \newcommand{\style}{\SetChild{id=Idstylei}\stepcounter{stylectr}} %% does not work %% command to expand the argument before the \SetChild (see https://tex.stackexchange.com/a/133768/430417) %\def\expandArg #1#2{\expandafter\expandArgaux\expandafter{#2}{#1}} %\def\expandArgaux #1#2{#2{#1}} %\newcommand{\style}{\expandArg{\SetChild}{id=Idstyle\roman{stylectr}}\stepcounter{stylectr}} \begin{document} \begin{table} \SetTblrOuter{expand=\style} \begin{tblr} { colspec=lll, cell{Idstylei} = {red9} } \style 1 & \style 2 & 3\\ \end{tblr} \end{table} \end{document} My goal is that, every time I call \style, the cell is given the id Idstyle{ctr} where {ctr} is a roman number (or anything that will yield a valid tblr id name). For instance, in the above code, only the first cell should have red background. I have tried several related solutions (1 2) but none seems to be working, or at least none that I can make to work. Edit: weird behaviour from tabularray, if I try to use the line \newcommand{\style}{\SetChild{id=Idstyle\roman{stylectr}}\stepcounter{stylectr}}, the code compiles but does not work (no cell has id Idstylei or even Idstyle), and an extra comma , appears left of the table. Does anyone knows where this comma is coming from?

Can someone help me create a macro like \MyList{A;B;C;D;E;F} which returns “A, B, C, D, E[,] respectively F" independently on how many ”arguments” (2+) that are specified and also support math, e.g. \MyList{\(A\);\(B\);\(C\);\(D\);\(E\);\(F\)} ? (I used the [,] notation since I’m not sure if the Oxford comma is used today.) If the number of arguments is two; \MyList{A;B} I would like it to return “A respectively B”. Edit: I tried using sinuitx but it might not be suitable for this task as it mainly(?) handles numbers. Here is a test \documentclass{article} \usepackage{siunitx} \begin{document} \numlist[parse-numbers=false]{A;2;3} \numlist[parse-numbers=false]{\text{A};2;3} \numlist[parse-numbers=false]{\(A+B\);2;3} \end{document} but it gives an error on the last line and I would like to have ”roman letters” if no ”math mode” is used, and avoid using \text{}.

Can I configure this loop, or a similar loop, to add rows until the end of the text body is reached? A small gap at the end will probably be unavoidable.

Sorry everyone. I just did an update, which was probably a mistake, and encountered another problem with hyperref. For years I've been using a workaround which I borrowed from a journal, and it worked. Well, I understand that this is an undocumented feature, but there seems (seemed?) to be no other way to have everything numbered consecutively. Here's a minimal example: \documentclass{amsart} \usepackage{hyperref} \newtheorem{theorem}{Theorem}[section] \makeatletter \let\c@equation\c@theorem \let\theequation\thetheorem \makeatother \begin{document} \section{1} \begin{equation} a=b\label{1} \end{equation} \newpage \section{2} \begin{equation} c=d\label{2} \end{equation} \newpage \eqref1 \eqref2 \end{document} Both links lead to eqn. 1.1, and the log reports multiple anchors with the same name. What would the new hack be? Or is there a documented way now to have all theorems, lemmas, ... and equations numbered consecutively within sections and, at the same time, have \autoref work correctly?

I'm trying to create a LaTeX document where I have several images stacked vertically, with no extra vertical space between them, and only one caption for all images (appearing under the last image). The problem is that each \IMG creates a separate figure, so each image gets its own caption and there’s extra vertical space between images. What I want: Multiple images stacked vertically with no extra vertical space. Only one caption for all images (appearing under the last one). Allow overlays on the images (x, y, text). This is how it should look like: The code what I got from taiwan12 with little modification (link: https://tex.stackexchange.com/a/760076/287423) : \documentclass{report} \usepackage{graphicx} \usepackage{float} \usepackage{xcolor} \usepackage{xparse} \ExplSyntaxOn % variables \tl_new:N \l_taiwanxii_image_tl \tl_new:N \l_taiwanxii_caption_tl \tl_new:N \l_taiwanxii_shortcaption_tl \tl_new:N \l_taiwanxii_label_tl \tl_new:N \l_taiwanxii_pos_tl \fp_new:N \l_taiwanxii_scale_fp \fp_new:N \l_taiwanxii_overlayscale_fp \clist_new:N \l_taiwanxii_x_clist \clist_new:N \l_taiwanxii_y_clist \clist_new:N \l_taiwanxii_text_clist % keys \keys_define:nn { taiwanxii } { image .tl_set:N = \l_taiwanxii_image_tl, caption .tl_set:N = \l_taiwanxii_caption_tl, shortcaption .tl_set:N = \l_taiwanxii_shortcaption_tl, label .tl_set:N = \l_taiwanxii_label_tl, pos .tl_set:N = \l_taiwanxii_pos_tl, scale .fp_set:N = \l_taiwanxii_scale_fp, overlayscale .fp_set:N = \l_taiwanxii_overlayscale_fp, x .clist_set:N = \l_taiwanxii_x_clist, y .clist_set:N = \l_taiwanxii_y_clist, text .clist_set:N = \l_taiwanxii_text_clist, } \NewDocumentCommand{\IMG}{m} { % reset \tl_clear:N \l_taiwanxii_image_tl \tl_clear:N \l_taiwanxii_caption_tl \tl_clear:N \l_taiwanxii_shortcaption_tl \tl_clear:N \l_taiwanxii_label_tl \tl_clear:N \l_taiwanxii_pos_tl \tl_clear:N \l_taiwanxii_pos_tl \clist_clear:N \l_taiwanxii_x_clist \clist_clear:N \l_taiwanxii_y_clist \clist_clear:N \l_taiwanxii_text_clist \tl_set:Nn \l_taiwanxii_pos_tl {H} \fp_set:Nn \l_taiwanxii_scale_fp {1} \fp_set:Nn \l_taiwanxii_overlayscale_fp {1} \keys_set:nn { taiwanxii } { #1 } % shortcaption \tl_if_empty:NT \l_taiwanxii_shortcaption_tl { \tl_set_eq:NN \l_taiwanxii_shortcaption_tl \l_taiwanxii_caption_tl } \use:e { \exp_not:N \begin{figure}[\l_taiwanxii_pos_tl] } \centering \sbox0{\includegraphics[scale=\fp_use:N \l_taiwanxii_scale_fp]{\l_taiwanxii_image_tl}} \usebox0 \int_zero:N \l_tmpa_int \clist_map_inline:Nn \l_taiwanxii_x_clist { \int_incr:N \l_tmpa_int \tl_set:Nn \l_tmpa_tl {##1} \tl_set:Nx \l_tmpb_tl { \clist_item:Nn \l_taiwanxii_y_clist { \int_use:N \l_tmpa_int } } \tl_set:Nx \l_tmpc_tl { \clist_item:Nn \l_taiwanxii_text_clist { \int_use:N \l_tmpa_int } } \rlap{ \hspace{\dimexpr \l_tmpa_tl\wd0-\wd0\relax} \raisebox{\dimexpr \ht0-\l_tmpb_tl\ht0\relax}{ \makebox[0pt][l]{ \raisebox{-\height}{ \scalebox{\fp_use:N \l_taiwanxii_overlayscale_fp}{ \fcolorbox{black}{white}{ \shortstack[c]{\l_tmpc_tl} } } } } } } } \caption[\l_taiwanxii_shortcaption_tl]{\l_taiwanxii_caption_tl} \label{fig:\l_taiwanxii_label_tl} \end{figure} } \ExplSyntaxOff \begin{document} \listoffigures \IMG{ image = example-image, caption = Caption I, shortcaption = Caption, label = figA, pos = H, scale = 0.6, x = {0.0,0.5,0.2,0.7,0.8}, y = {0.0,0.2,0.3,0.65,0.9}, text = {AA\\BB,AABB,A,B,C}, overlayscale = 0.75, } \IMG{ image = example-image, caption = Caption II, shortcaption = Caption, label = figB, pos = H, scale = 0.6, x = {0.2,0.5}, y = {0.2,0.3}, text = {AABB,A}, overlayscale = 1, } \end{document}

I apologized if this is a duplicate. What is the best way to draw such figures with tikz (or other packages)? For the time being just the potato like figure. I do not care for the vectors and the infinitesimal mass element. I do not want someone to do the work for me. Just some advice or suggestions.

I want to add a topright math kern (aka cut-in or staircase kerning) to DOUBLE-STRUCK CAPITAL R (Hex value: 0x211D, Code point: U+211D). I tried the method as shown in this answer of mickep, but it does not seem to work here. \documentclass{article} \usepackage{fontsetup} \directlua{ local kerns = { ["NewCMMath-Book"] = { [0x211D] = { topright = { { kern = -500 } } }, } } local function addkerns(tfmdata) if tfmdata.mathparameters then local kerns = kerns[tfmdata.properties.fontname] if kerns then local characters = tfmdata.characters for unicode, specification in pairs(kerns) do local character = characters[unicode] if character and not character.mathkerns then character.mathkerns = specification end end end end end fonts.handlers.otf.features.register { name = "mathkerns", description = "additional math kerns", default = true, initializers = { position = 1, base = addkerns, node = addkerns, } } } \usepackage{lua-visual-debug} % The absence of a red rectangle between the doublestruck R and the superscript n seems to indicate that math kerning is not being used, if I understand correctly. \begin{document} \(\symbb{R}^n\) \end{document} While I am using LuaLaTeX with unicode-math, answers for other engines such as ConTeXt and OpTeX are also welcome, if the resulting code is different. Edit: I have tried loading the fonts manually, but that also does not seem to work. \documentclass{article} \directlua{ local kerns = { ["NewCMMath-Book"] = { [0x211D] = { topright = { { kern = -100 } } } } } local function addkerns(tfmdata) if tfmdata.mathparameters then local kerns = kerns[tfmdata.properties.fontname] if kerns then local characters = tfmdata.characters for unicode, specification in pairs(kerns) do local character = characters[unicode] if character and not character.mathkerns then character.mathkerns = specification end end end end end fonts.handlers.otf.features.register { name = "mathkerns", description = "additional math kerns", initializers = { position = 1, base = addkerns, node = addkerns, } } } \usepackage{unicode-math} \setmainfont{NewCM10-Book.otf} \setmathfont[ StylisticSet={3}, BoldFont = NewCMMath-Bold.otf, RawFeature=+mathkerns ]{NewCMMath-Book.otf} \usepackage{lua-visual-debug} \lvdset{glyph={show=true}} \begin{document} \(\symbb{R}^n\) \end{document}

I'm trying to set up some parameters of nodes from lua code. I don't understand why the first version works but not the second. \documentclass[border=10pt]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} \node [ color=\directlua{ tex.print("red") } ] {A}; \node [ \directlua{ tex.print("color=red") } ] {B}; \end{tikzpicture} \end{document} To me it looks like that these two directlua sections should produce the exact same output, but B fails with the following error message: ! Package pgfkeys Error: I do not know the key '/tikz/color=red' and I am going to ignore it. Perhaps you misspelled it.

I'm trying to use \qedhere with the ams classes to set a proof endmark at the end of an align environment. But doing so removes the number from that equation! This problem doesn't happen with a single numbered equation. Here are some examples. In the last one, I have a sort of hack from this question that adds a paragraph break and then a negative \vspace. But, the spacing isn't quite right and I wouldn't want to manually adjust it for each different environment. I've also seen a similar suggestion for a multi-line display. Is there not a better way? \documentclass{amsart} \begin{document} \begin{proof} Numbered equation, qedhere at right. \begin{equation} x+y\qedhere \end{equation} \end{proof} \begin{proof} Align environment; qed on newline \begin{align} x & = 2\\ y & = 3 \end{align} \end{proof} \begin{proof} Align environment; using qedhere blocks the final equation number \begin{align} x & = 2\\ y & = 3\qedhere % <---- want a number here too \end{align} \end{proof} \begin{proof} Align environment; paragraph break and negative vspace \begin{align} x & = 2\\ y & = 3 \end{align} \par\nopagebreak\vspace{-\baselineskip}\mbox{} \end{proof} \end{document} Note: Several related questions, like this one for the cases environment, have comments suggesting that it's just bad style to end a proof with a displayed equation. Leaving that aside, I'm really interested in different endmarks for different environments. The proof environment is just the simplest way to display the issue with \qedhere and align. Note 2: I also see suggestions that ntheorem handles endmarks better. I've used ntheorem for many years, but it hasn't been updated since 2011. I'm looking for a better solution using the new begin/end environment hooks. I had hoped \qedhere in the appropriate hook could do the job.

Consider the following minimal example where I want to draw a rectangle behind a sequence of numbers (to highlight them): \documentclass{article} \usepackage{tikz} \usetikzlibrary{backgrounds,calc} \NewDocumentCommand{\tikzmark}{ m }{\tikz[overlay, remember picture] \node (#1) {};} \newcounter{seq} \NewDocumentCommand{\seqstart}{}{% \stepcounter{seq}% Start a new sequence \tikzmark{seq-start-\theseq}}% Set start marker \NewDocumentCommand{\seqend}{}{% \tikzmark{seq-end-\theseq}% Set end marker \tikz[remember picture, overlay] \scoped [on background layer] \fill [fill=blue!10!white] ($(seq-start-\theseq.south west) + (-0.5pt,1pt)$) rectangle ($(seq-end-\theseq.south east) + (0.5pt,1.1\normalbaselineskip)$);% } \begin{document} \[ 12, 15, 8, 11, 4, 7, 0, 3, 16, 19, 12, 15, 8, 11, 4, 7, 0, 3, \ldots \] \[ \seqstart{}12, 15, 8, 11, 4, 7, 0, 3, 16, 19\seqend{}, 12, 15, 8, 11, 4, 7, 0, 3, \ldots \] \end{document} The idea is that \seqstart would set a (counter-driven) \tikzmark representing the start of the sequence to be marked. Then \seqend would set a \tikzmark at the end and highlight it using the background layer. The counter allows for multiple such sequence marking within a larger document. However, the output shows that the rectangle highlighting a part of the sequence is not being drawn on background layer as requested. Why is that? How can I ensure the rectangle is drawn on the background layer behind document/text elements? The backgrounds library documentation (in the tikz documentation, section 45) mentions that on background layer can only be used inside a {scope} or \scoped, which is done above.

First off, here is my setup because I am certain that must be part of the problem. I'm using: texlive 2025 VS Code with these extensions: LaTeX by Mathematic Inc LaTeX Workshop by James Yu I have a LaTeX document that used to build just fine. I recently tried switching over to using the tcolorbox package instead of the soul package for highlighting in that document. As part of that process, I was getting some errors, and from reading various posts online for similiar issues I suspected I had an outdated texlive distribution so ended up trying to update everything with this on my command line: tlmgr update --all This appeared to fix the errors with tcolorbox, but I then realized that tcolorbox does not break across lines nicely so switched back to using soul. But now my document will not build. It is stuck in an infinite loop or something, the status at the bottom of VS code has the spinning circular arrows next to "Build" and it just spins forever. I have narrowed the problem down to when I use \hl inside of a longtable. Minimum working code is below. If I uncomment the commented line, I get the building-forever behavior. \documentclass{article} \usepackage{longtable} \usepackage{soul} \usepackage{xcolor} \begin{document} \sethlcolor{yellow}\hl{Test text} \begin{longtable}{ll} Column 1 & Column 2\\ % \hl{Test text} & Entry 2 \\ \end{longtable} \end{document} I have completely removed and re-installed my texlive installation and am still getting the same result. When I click "Kill LaTeX compiler process" twice to stop the infinite build, I get a popup saying "Recipe terminated with error". I click on "Open Compiler log" and get this: Initial Win CP for (console input, console output, system): (CP437, CP437, CP1252) I changed them all to CP1252 Rc files read: NONE Latexmk: This is Latexmk, John Collins, 15 June 2025.

In this answer https://tex.stackexchange.com/a/133357 to a question regarding TikZ I found the following comment inside a \tikzset: % Use csname so catcode of @ doesn't have do be changed. This leaves me wondering if using \csname has any advantage over changing the catcode of @ by wrapping \tikzset with \makeatletter - which inside a package wouldn't even be neccesary since inside a package @ is of catcode letter by default. Is the use of \makeatletter potentially problematic (in general or inside pgfkeys)? If so: In which cases is it advisable to use \csname instead of \makeatletter? As far as I can imgine it (practically?) should be just a matter of taste, otherwise using such code inside a package where @ is of catcode letter would be problematic?!

I love LaTeX, but I also love french typography and I noticed that babel does not really add a thin space before the colon/semicolon: \documentclass{article} \usepackage[french]{babel} \addto\extrasfrench{% \renewcommand{\FBcolonspace}{\nobreak\thinspace}% } \begin{document} \large Le canard: un animal avec deux pattes. \end{document} Built with: latexmk -lualatex test.tex If I manually do it, the result is visually much better. \begin{document} \large Le canard\nobreak\thinspace: un animal avec deux pattes. \end{document} Is there a way to tweak babel to do it right?
