I face the following problem since I migrated to texlive 2025 with the deprecation of gentium-tug When I build my books on a minimnal installation I get the following error (/home/runner/texlive/texmf-dist/tex/latex/fontspec/fontspec.sty (/home/runner/texlive/texmf-dist/tex/latex/fontspec/fontspec-luatex.sty (/home/runner/texlive/texmf-dist/tex/latex/base/fontenc.sty) (/home/runner/texlive/texmf-dist/tex/latex/fontspec/fontspec.cfg))) luaotfload | db : Reload initiated (formats: otf,ttf,ttc); reason: File not found: "Gentium-Regular.ttf". !

My goal is to get a rectangle like the one below, but with text in the nested rectangles. Line types could be for example the following: I saw tikz: Multiple splits of rectangle, but it does not answer the question on the line types. Beyond that, I am a beginner using Tikz, and I'd like the answer explained, since the linked answer is complex to understand. Thanks!

Not sure what is wrong with my minipage figures, this is the same kind of layout that I have used in the past with no problems, but for some reason now it is not working. I am trying to have all four figures have the same width, with all the captions also aligned on the same line. The following code \documentclass[12pt, a4paper, twoside, openright]{article} \usepackage{graphicx} \usepackage{float} \usepackage{caption} \begin{document} \begin{figure}[h!] \centering \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_1.png} \caption{Quartier 1}\label{fig:q1} \end{minipage}\hfill \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_2.png} \caption{Quartier 2}\label{fig:q2} \end{minipage} \hfill \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_3.png} \caption{Quartier 3}\label{fig:q3} \end{minipage} \begin{minipage}{0.25\textwidth} \centering \includegraphics[width=0.9\textwidth]{images/quartier_4.png} \caption{Quartier 4}\label{fig:q4} \end{minipage} \end{figure} \end{document} returns the following result:

I have an issue with the following code, kindly provided by egreg some time ago answer by egreg. It worked well, but I recently noticed an unwanted behavior. I am not sufficiently familiar with expl3 to fix it myself, nor do I fully understand how the code works. \ExplSyntaxOn \NewDocumentCommand{\pc}{m} % projective coordinates { \seq_set_split:NVn \l_tmpa_seq \c_colon_str { #1 } ( \seq_use:Nn \l_tmpa_seq { \mspace{1\medmuskip}{:}\mspace{1\medmuskip} } ) } \ExplSyntaxOff \documentclass{article} \usepackage{amsmath} \begin{document} \[ \begin{aligned} &(a:b:c) & & (1:-1:2) & &\qquad\verb|standard|\\ &\pc{a:b:c} & & \pc{1:-1:3} & &\qquad\verb|with \pc command|\\ &(a:-b:c) & & (1:-2:3) & &\qquad\verb|standard|\\ &\pc{a:-b:c}& & \pc{1:-2:3} & &\qquad\verb|with \pc command| \end{aligned} \] \[ \pc{a,b,c,d}\quad \pc{a;b;c;d,e,f:g:h:i,l} \] \end{document} Here is the output of the minimal working example: The actual issue appears when a coordinate other than the first is negative (for example \pc{a:-b:c} or \pc{1:-2:3}), where the spacing/output differs from the standard notation. As an aside, I also do not understand why commands such as \pc{a,b,c} or \pc{a;b;c:d} produce the output they do. Could someone explain what is happening here, and how to modify the macro so that it behaves correctly in all cases?

This example \hfuzz=10000pt \hsize=0pt \noindent\hskip0pt thirteen --- dimensional \bye is equivalent to \hfuzz=10000pt \hsize=0pt \noindent\hskip0pt thirteen\hskip0pt---\nobreak\hskip0pt dimensional \bye Why in the first case space is equivalent to \hskip0pt and in second case --- to \nobreak\hskip0pt (i.e., why in the second case \nobreak is not needed before space) ? BTW, in the following example if we delete \nobreak before second \space, the breaking decision after --- is changed. \hfuzz=10000pt \hsize=7.29cm \noindent Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

I would like to add a very large picture on a title page, covering the whole page with a large offset (picture pasted to the upper-left side of the page), blended on the page background (below the title, author's name and other text elements), with some transparency effect, and background blending effect. How should we achieve this? The picture is supposed to be partly shown on the page, about half of it showing on the upper-left side, like an "intrusion" on the page (sorry for the bad english description. I hope you get the picture). Here's a MWE to be modified, showing a title page prototype: \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt]{geometry} \usepackage{titlesec} \usepackage{graphicx} \usepackage[dvipsnames]{xcolor} \usepackage{float} \usepackage{fancyhdr} \usepackage[titles]{tocloft} \usepackage{shadowtext} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \frontmatter % Title Page : \begin{titlepage} \definecolor{lightbrown}{RGB}{177, 149, 93} \definecolor{darkbrown1}{RGB}{58, 41, 26} \definecolor{darkbrown2}{RGB}{50, 30, 0} % Frame : \begin{tikzpicture}[remember picture, overlay] \draw[line width = 1in,color = white] ($(current page.north west) + (0.25in,0.25in)$) rectangle ($(current page.south east) + (0.25in,-0.25in)$); \draw[line width = 0.25pt,color = black] ($(current page.north west) + (0.75in,-0.25in)$) rectangle ($(current page.south east) + (-0.25in,0.25in)$); %\draw[line width = 1pt,color = darkbrown1] ($(current page.north west) + (1in,-0.5in)$) rectangle ($(current page.south east) + (-0.5in,0.5in)$); \end{tikzpicture} \shadowoffsetx{2.5pt} \shadowoffsety{3.5pt} \shadowcolor{gray!80} \definecolor{pagetitre}{RGB}{150,120,100} \pagecolor{pagetitre} \centering \vspace*{\baselineskip} \vfill {\textcolor{black}{\fontsize{26}{0}\selectfont\sffamily\textbf{\shadowtext{Some Nice Title Here}}}} \\[2.5\baselineskip] {\textcolor{black}{\huge\sffamily\scshape Someone}} \vfill \vfill \includegraphics[width=11cm]{example-grid-100x100pt} \vfill {\textcolor{black}{\Large\selectfont\sffamily\scshape Some copyright notice}} \end{titlepage} \pagecolor{white} Blabla \end{document} So how can I add a very large picture blended with the page background colour, with some transparency effect, and a large up-left offset? The large picture should fit inside the frame defined with the tikzpicture environment, and stay below all text on the title page.

I am trying to include an image in the center part of the header (between the course name and semester, and the professor's name. I have tried but it keeps moving, or hiding text behind.

This is my current effort: \documentclass{article} \usepackage{pstricks} \usepackage{graphicx} \begin{document} \rotatebox{90}{% \begin{pspicture}(5,4) \psgrid \end{pspicture} } \end{document} How do I persuade gv (and my printer), to present it in landscape? Of course I have to play with the actual numbers. Eventually something like conventional graph paper on it's side.

Missing \endcsname inserted. <to be read again> \def l.28 \glsXpageXglsnumberformat{}{1}}} % ? though the test-glossaries.sls files are identical in both cases. Do you understand what's going on?

in my bibliographies I often have references to older literature in various languages, for which English translations exist, like: @BOOK{Pto-00, AUTHOR = {{{\foreignlanguage{greek}{Κλαύδιος Πτολεμαῖος}} [Klaúdios Ptolemaíos]}}, sortname = {Ptolemaios}, shortauthor = {Ptolemaíos}, TITLE = {{{\foreignlanguage{greek}{μέγιστη σύνταξις}} [megíste sýntaxis] [\textnormal{{\foreignlanguage{arabic}{المجسطي}}} al-maǧisṭī] [Almagest] }}, sorttitle = {Almagest}, YEAR = {2nd Century AD}, address = {Alexandria (EG)}, related = {Pto-84}, relatedtype = {translatedbyas}, langid = {greek}, } @BOOK{Pto-84, AUTHOR = {{{\foreignlanguage{greek}{Κλαύδιος Πτολεμαῖος}} [Klaúdios Ptolemaíos]}}, TITLE = {Ptolemy's Almagest}, translator = {Toomer, G.J.}, editor = {Toomer, G.J.}, YEAR = {1984}, PUBLISHER = {Duckworth}, address = {London (UK)}, url = {https://classicalliberalarts.com/resources/PTOLEMY_ALMAGEST_ENGLISH.pdf}, } Unfortunately, I could not find in the bibLaTeX manual a list of the relatedtype-options (editedby, editedbyas, translatedby...) and their respective use. It would help me to make more effective use of this facility. Does anybody know of such a thing?

I am currently designing a conlang that requires a custom writing system with many glyphs. I am unsure what the best way to insert these glyphs into a LaTeX document is. My current approach is to use METAFONT, but I will likely use more than 256 glyphs. If possible, I would like to be able to type the characters through name (e.g. hem- kron-) but METAFONT does not support 3+ character ligatures. Are there any other ways that would be better for my use case? TikZ or METAPOST, for instance? (Because of the way the writing system for the conlang works, I also need the system to work in math mode and be able to set the kerning between characters to 0 - i.e. no inter-character space) Also, if it's relevant, I wasn't planning to type the text out by hand - I was going to have a lua script to put the character names in and output the actual characters.

How to use cmd=\mycustomcommand instead of \\ to break lines from tabularray package.

I am using the vscodeicons and vectorlogos packages to include small icons in my document. Consider this MWE: \documentclass{article} \usepackage{vscodeicons,vectorlogos} \begin{document} Inline \vscodeicon[filetype]{wolfram} version Geogebra \vectorlogo[icon]{geogebra} \end{document} To my eyes, the icons appear slightly shifted downwards with respect to the surrounding text. Are they already correctly aligned in the packages, or would it be better to tweak them (e.g., with \raisebox or package options such as height=auto/dstrut=false) so that they sit exactly on the baseline like the surrounding text? If some adjustment is recommended, what would be a robust way to align them in inline text without breaking the line spacing?

I am asked to format the spacing of the captions of figures and tables as follows: captions of figures above: 6 pt below: 18 pt captions of tables above: 18 pt below: 9 pt I tried implementing this as shown in the following MWE, yet, the result seems odd, especially the gap below the caption of the figure and below the table, respectively, and the proceeding text. Why is that or, alternatively, how can this be formatted properly? \LoadClass[a4paper,12pt,parskip=full-]{scrreprt} \RequirePackage[font=footnotesize,labelfont=bf,singlelinecheck=false]{caption} \captionsetup[figure]{aboveskip=6pt,belowskip=18pt} \captionsetup[table]{belowskip=18pt,aboveskip=9pt} \RequirePackage{float} \begin{document} This text refers to Figure \ref{figure}: \begin{figure}[H] \caption{Caption of Figure} \label{figure} \end{figure} This text refers to Table \ref{table}: \begin{table}[H] \caption{Caption of Table} \label{table} \begin{tabular}{ |c| } \hline Table\\ \hline \end{tabular} \end{table} Text. \end{document}

I use lualatex and hyperref to create a large PDF file of documentation with extensive crossreferencing to figures, tables, sections, list items, pages, etc using hyperref and varioref. The file then gets split (by a script which writes pdftk commands) into separate PDF files for prelims, chapters, appendices, references, etc. Is there a way to rewrite the crossreferencing commands so that they will work both in the monolithic document and between the split documents? Or do I need to create both the single-file PDF and the separate PDFs using LaTeX, rather than by splitting the big one?

I'm using biblatex-chicago and find that the spacing between volumes and pages of articles is inconsistent. What I mean by this is that the spacing depends on whether the issue number is present. Consider this MWE: \documentclass{article} \usepackage{filecontents} \usepackage[authordate,backend=biber]{biblatex-chicago} \addbibresource{refs-mwe.bib} \begin{filecontents}{refs-mwe.bib} @article{Other2021, author={A.

That is, how do I get rid of the spaces before and after the "(3):" in the second reference? Note: It is possible to add a space before the pages in the first reference by adding \renewcommand{\postvolpunct}{\addcolon\addspace}, but this is not what I want.

In particular, both the subscripts (indices) and the superscripts (T) are properly set and readable: However, when I compile with lualatex, the subscripts overlap with the succeeding line: I've also created a gif for a better comparison: My question is: How can I avoid the overlap? (My wish would be to consistently raise the subscripts. I'd like to avoid increasing the row distance, because then the rows on the l.h.s. would not properly align with the rows on the r.h.s.)

Why does the LaTeX example 𝑨 \mathbf{\mathit{A}} become italic but not bold italic font?, or 𝙂 \mathsf{\mathbf{\mathit{G}}} remain sans serif and bold italic? I'd like to use the sans serif italic/bold italic options from the \usepackage{isomath} to represent this. It must have the function of stacking LaTeX math fonts, It would be better to mix and match LaTeX math font formats randomly. For example in font format glyphs display: 𝑨 \mathbf{\mathit} and 𝕬 \mathbf{\mathfrak}/ 𝗔 \mathbf{\mathsf}please use \bm{} + \mathit/\mathfrak/\mathsf in working this command style 𝓐 \mathbf{\mathscr} or 𝓐 \mathscr{\mathbf} please use \pmb{} + \mathscr in working this command style

Here's my try using \textwidth, but it crosses the text area. \documentclass[a4paper]{article} \usepackage{graphicx} \usepackage[showframe]{geometry} \setlength\parindent{0pt} \begin{document} \includegraphics[width=.45\textwidth]{example-image-9x16} \hspace{.1\textwidth} \includegraphics[width=.45\textwidth]{example-image-9x16} \end{document}

In the past, something such as \textit{this\par that} would throw an error, because the \textit command was "short" (it could not span paragraphs). But I now see (TeXlive 2026) that is is "long" (can span paragraphs). This is verified by inspecting code in file latex.ltx even though that file is not necessarily loaded. Even AI did not know that! Or did I hack something, and forgot about it?
