In plain TeX (not eTeX, and definitely not LaTeX), I am trying to test if a macro argument was just previously used (the last time the macro was invoked). The idea is I am trying to create an extremely crude "index", and I want to print all the references to the same entry on the same line. (The entries are already sorted, this is literally just a printing problem. I cannot determine if the current entry coincides with the entry "currently being worked on".) A minimal working example: \def\currentparam{} \def\printrefs#1#2{% \if#1\currentparam% -- apparently always false!? , #2% \else% \gdef\currentparam{#1}% \par\noindent#1 #2% \fi} \printrefs{Hilbert, David}{17} \printrefs{Hilbert, David}{23} \printrefs{Hilbert's programme}{2} \printrefs{Martin-L{\accent "7F o}f, Per}{3} \printrefs{Martin-L{\accent "7F o}f, Per}{19} \bye This will (sadly) print five lines, looking like: Hilbert, David 17 Hilbert, David 23 Hilbert's programme 2 Martin-L{\accent "7F o}f, Per 3 Martin-L{\accent "7F o}f, Per 19 Instead of the sought behavour of printing three lines: Hilbert, David 17, 23 Hilbert's programme 2 Martin-L{\accent "7F o}f, Per 3, 19 Something is going wrong with the \if#1\currentparam line to always evaluate to false, but the solution to the bug eludes me.

When I check the following using Adobe Acrobat's Accessibility Checker, my theorem numbering gets hit with Lbl and Lbody issues. Is there a way to avoid that? I know that getting rid of the numbers will do it, but I was hoping to keep the numbers for referencing later on.

The following MCE: \documentclass[french]{article} % \usepackage{fnpct} \usepackage{babel} \pagestyle{empty} \begin{document} Foo\footnote{Bar.}\footnote{Baz.}. \end{document} compiled with current lualatex, typesets the footnotes according to the French typographic rules: Bar. Baz. But, if fnpct is loaded, that's not the case since the footnotes are typeset as follows: ¹Bar. ²Baz. At least with TeX Live 2025, we got the expected result even when fnpct was loaded. Here's what has changed since then: LuaHBTeX 1.22.0 (TL 2025) → 1.24.0 (TL 2026) keyval.sty 2022/05/29 v1.15 → 2026-05-17 v1.15 expl3.sty 2025-10-24 → 2026-05-26 l3backend-luatex.def 2025-10-09 → 2026-02-18 babel.sty 2025/10/22 v25.14 → 2026/06/14 v26.9 french.ldf 2025-08-15 v4.0e → 2026-06-06 v4.1a Do you know how to nowadays retrieve the previous, expected, behavior? Edit With current TL 2026, the result is the same with pdftex and with lualatex but, with TL 2025, the result is the expected one: not with pdflatex with lualatex.

I was trying to answer another question, but I can't create a customized integral that has the subscripts in the correct position. Why? egreg has already answered the other question.

I am designing playing cards, and I use a print service (https://meinspiel.de if that's relevant). I create my cards with a heading styled with tikz, like so: \documentclass{article} \usepackage[paperwidth=65mm,paperheight=97mm, margin=7mm]{geometry} \pagestyle{empty} \RequirePackage[x-4]{pdfx} \setCMYKcolorprofile{coated_FOGRA39L_argl.icc} {Coated FOGRA39} {FOGRA39 (ISO Coated v2 300\% (ECI))} {http://www.argyllcms.com/} \usepackage[overprint]{colorspace} \RequirePackage{tikz} \usetikzlibrary{positioning,shapes,calc,backgrounds} \definecolor{blue1}{cmyk}{0.6818,0.3939,0,0.7412} \definecolor{blue2}{cmyk}{0.6339,0.2768,0,0.5608} \tikzset{ pics/heading/.style={code={ \node[anchor=north west] (heading) at ($(current page.north west) + (7, -7)$) {\textoverprint[0]{\textcolor{white}{\textsf{#1}}}}; \begin{scope}[on background layer] \fill[top color=blue1, bottom color=blue2] (current page.north west) -- (heading.south west-|current page.north west) -- (heading.south east) .. controls +(right:5) and +(left:5) .. +(10, 2) -| (current page.north east) -- cycle; \end{scope} }} } \begin{document} \begin{tikzpicture}[x=1mm, y=1mm, remember picture, overlay] \pic {heading={My Heading}}; \end{tikzpicture} \end{document} As you can see, I set the card's dimensions, specify PDF/X-4 output and the ISO Coated v2 300% (ECI) color profile just like the print service requires. Then I enable overprint (unsure whether this is relevant for my issue) for black text (but the heading is white, so I disable it there again). I define a tikz pic to use for drawing the heading of each card. Finally, I create a document with a single card that uses that pic as heading. The result looks like this: I gave that to the printing service, and they printed the heading as two areas split horizontally with different colors, instead of the gradient. When I asked them what the problem is, they answered this (translated from German): The data is set up in a strange way. The gradient consists of two parts, which lead to it being cut back during conversion. Also, the size of the gradient is extremely huge. I don't exaggerate. It has a width of 352777777777,425mm, i.e. 352.777,78km! While we do have meter scale from time to time, I've never seen kilometers. (The circumference of Earth at the equator is about 40.075 km to put that into context.) It may be that this is why there was an error during conversion. We suggest to embed the gradient as picture to avoid such errors. Also, when gradients are pictures, the print is cleaner and smoother. So, I guess my question is: How do I create the gradient so that the print service is happy? I don't feel like I have enough control over whatever tikz does here.

I've seen an acquaintance which uses InDesign struggle with things which could be easily automated in LaTex. They are writing a tabletop rpg book which has lots of varied format illustrations, generally a two column layout, text flowing around non square pictures and full page art. I've had a look at http://framabook.org/tout-sur-latex/ and other entries from List of books written in LaTeX with the source available Yet i did find that they do not make a convincing arguement to switch away from InDesign. Can someone think of an existing book for TTRPGs or that is otherwise art heavy and fun to browse about a topic that doesn't feature equations promently¹ which has available source code? [1] Equations can be scary to some and would detract from the point that it LaTex can be used for something so "artsy".

I want to reproduce a cannon considering in old style (one of these) considering that I have not seen a specific symbol. Does anyone know if there’s a symbol that resembles one of this image? I have not found anything.

tldr: I want to have an exact replica of the following table with tabularray. As you can see, the blue borders are double-lined, and the first horizontal double line only intersect the first vertical double line on from the left, and intersect the second one from the right. They do not break the table into two. What I tried: \documentclass{article} \usepackage{tabularray} \begin{document} \begin{tblr}{ colspec = { X[c,m,mode=math] X[c,m,mode=math] X[c,m,mode=math] X[c,m,mode=math] }, width=8cm, rulesep = 1pt, hline{1,Z} = {wd=1.5pt}, hline{2} = {1}{-}{leftpos=1,rightpos=0,wd=0.5pt}, hline{2} = {2}{-}{leftpos=1,rightpos=0,wd=0.5pt}, vline{2} = {1}{-}{wd=0.5pt}, vline{2} = {2}{-}{wd=0.5pt}, vline{1,Z} = {wd=1.5pt}, vline{3,4} = {wd=0.5pt}, } 1 & 2 & 3 \\ 4 & 5 & 6 \end{tblr} \end{document} Result: The table breaks into 2, and the horizontal and vertical lines do not intersect like the Norway flag. Thanks in advance.

The dangerous bend symbol is not working when encapsulated in a macro. \documentclass[11pt]{article} \usepackage{fontspec}\setmainfont{STIX Two Text} \usepackage{unicode-math}\setmathfont{STIX Two Math} \usepackage[b5paper,margin=2cm,top=1cm]{geometry} \usepackage{graphicx} \usepackage{manfnt} \newcommand\danger{% \par\noindent \hangindent2em \hangafter1 \makebox[2em][l]\dbend% } \begin{document} \par\noindent \hangindent2em \hangafter1 \makebox[2em][l]\dbend NORMAL paragraph with NORMAL wrapping paragraph content paragraph content paragraph content paragraph content paragraph content paragraph content paragraph content paragraph content paragraph content paragraph content \danger Problematic paragraph! \end{document} Observations: Currently, the first paragraph has the dangerous bend symbol rendered correctly. The second paragraph, while seemingly equivalent in terms of \dbend symbol use, renders a small square for the symbol. If we remove the unicode-math line, both paragraphs work. But I do need the packages for my document. So my questions are: why is unicode-math not working with \dbend? And even if they don't work together, why is the macro encapsulation causing further problems?

I have tried this with both the latest release of kaobook and the latest version in the main branch. This is an MWE, which includes my current setup and mirrors the compilation using xelatex. Any advice would be greatly appreciated. % !TEX program = xelatex \documentclass{kaobook} % Load siunitx to provide the 'S' column type used in your table \usepackage{siunitx} \usepackage{booktabs} \begin{document} \mainmatter \chapter{Testing Memory Error} % This section is designed to trigger the "TeX capacity exceeded" % error seen in kaobook. \begin{table}[htbp] \centering % The \caption{} command is the likely trigger for the recursion loop in kaobook \caption[ML on ds2]{Results from our trained models on ds2} \label{tab:test} \begin{tabular}{lSSS} \toprule {blocking} & {n\_pairs} & {n\_pred} & {pred\_rate} \\ \midrule Title Canopy & \num{1883498} & \num{43085} & \num{0.0228} \\ bibhash & \num{7374} & \num{7374} & \num{0.9909} \\ attr. bl. & \num{441997} & \num{7876} & \num{0.0178} \\ \bottomrule \end{tabular} \end{table} \end{document} The problem goes away when I use a table* environment instead. I previously thought that this may be connected to my use of the packages caption and/or subcaption, but removing those as dependencies did not solve my problem. Now, I am assuming that kaobook does something weird with table captions?

Although this was mentioned last time: TeX chinese image poetry image text layout However, it seems no one has mentioned the layout of the snail's rotating circle text in the TeX code.

How can I define a big plus operator that works like \bigcup? ⅌ apply in tikz text symbols? % Source - https://tex.stackexchange.com/a/394912 % Posted by GuM, modified by community.

I'm trying to migrate from listings to piton, but unfortunately, piton doesn't have native support for Lua. From what I can understand of the documentation, I've modified lstlang2 and converted it to piton, but I don't understand how \NewPitonLanguage works or how to color things with \SetPitonStyle. This is my compiled file, but it's not producing the expected result: \documentclass{article} \usepackage[osf,nomath,mono=false,ScaleSF=0.95,ScaleRM=0.95]{libertinus-otf} \usepackage{sourcecodepro} \defaultfontfeatures[\ttfamily] { Numbers = OldStyle, Scale = 0.84249, Extension = .otf, } \setmonofont[ UprightFont = *-Regular, ItalicFont = *-RegularIt, BoldFont = *-Semibold, BoldItalicFont = *-SemiboldIt, RawFeature = {+zero,+ss01}]{SourceCodePro} \usepackage{unicode-math} \setmathfont[Scale = 0.95]{latinmodern-math.otf} \usepackage{piton} % (Pygments colors) \definecolor{pyg_comment}{HTML}{408080} \definecolor{pyg_string}{HTML}{BA2121} \definecolor{pyg_keyword}{HTML}{000080} \definecolor{pyg_builtin}{HTML}{008000} \definecolor{pyg_function}{HTML}{0000FF} \definecolor{pyg_punct}{HTML}{A020F0} % New languaje \NewPitonLanguage{SpintentLua}{ sensitive = true, alsoletter = {.}, morecomment = [l]{--}, morecomment = [s]{--[[}{]]}, morestring = [b]", morestring = [b]', morestring = [s]{[[}{]]}, morekeywords = [Delim]{ (, ), [, ] }, % Clase nativa: Keyword (Por defecto si no se especifica corchetes) morekeywords = { and, break, do, else, elseif, end, false, for, function, goto, if, in, local, nil, not, or, repeat, return, then, true, until, while }, % Clase nativa: Name.Builtin (Para funciones del sistema) morekeywords = [Name.Builtin]{ _ENV, _G, _PROMPT, _PROMPT2, _VERSION, arg, assert, collectgarbage, coroutine, coroutine.create, coroutine.isyieldable, coroutine.resume, coroutine.running, coroutine.status, coroutine.wrap, coroutine.yield, debug, debug.debug, debug.gethook, debug.getinfo, debug.getlocal, debug.getmetatable, debug.getregistry, debug.getupvalue, debug.getuservalue, debug.sethook, debug.setlocal, debug.setmetatable, debug.setupvalue, debug.setuservalue, debug.traceback, debug.upvalueid, debug.upvaluejoin, dofile, error, getmetatable, io, io.close, io.flush, io.input, io.lines, io.open, io.output, io.popen, io.read, io.stderr, io.stdin, io.stdout, io.tmpfile, io.type, io.write, ipairs, load, loadfile, math, math.abs, math.acos, math.asin, math.atan, math.ceil, math.cos, math.deg, math.exp, math.floor, math.fmod, math.huge, math.log, math.max, math.maxinteger, math.min, math.mininteger, math.modf, math.pi, math.rad, math.random, math.randomseed, math.sin, math.sqrt, math.tan, math.tointeger, math.type, math.ult, next, os, os.clock, os.date, os.difftime, os.execute, os.exit, os.getenv, os.remove, os.rename, os.setlocale, os.time, os.tmpname, package, package.config, package.cpath, package.loaded, package.loadlib, package.path, package.preload, package.searchers, package.searchpath, pairs, pcall, print, rawequal, rawget, rawlen, rawset, require, select, setmetatable, string, string.byte, string.char, string.dump, string.find, string.format, string.gmatch, string.gsub, string.len, string.lower, string.match, string.pack, string.packsize, string.rep, string.reverse, string.sub, string.unpack, string.upper, table, table.concat, table.insert, table.move, table.pack, table.remove, table.sort, table.unpack, tonumber, tostring, type, utf8, utf8.char, utf8.charpattern, utf8.codepoint, utf8.codes, utf8.len, utf8.offset, xpcall }, % Clase nativa: Name.Function (custom API) morekeywords = [Name.Function]{ register_tex_cmd, scan_string, set_macro, clean_lexical_accents, luafun_spmoney_parse, __spintent_money_render, luafun_spdate_parse, luafun_sptime_parse, spintent_gcd_algorithm } } \SetPitonStyle { Comment = \color{pyg_comment}\fontfamily{lmtt}\small\itshape, String = \color{pyg_string} , Keyword = \color{pyg_keyword}\bfseries , Name.Builtin = \color{pyg_builtin}\bfseries , Name.Function = \color{pyg_function} , Delim = \color{pyg_punct}, } \NewPitonEnvironment{luapiton}{ !O{} } {\PitonOptions{language=SpintentLua, #1}}{} \begin{document} \begin{luapiton} -- "Submódulo Financiero: Core de validación estructural spintent" local token = token local luatexbase = luatexbase function luafun_spmoney_parse() -- Captura bidireccional nativa libre de expansiones TeX local raw_input = token.scan_string() local clean_num = string.gsub(raw_input, "%s+", "") if not clean_num:match("^[%+%-]?%d+$") then token.set_macro("l__spintent_money_status_str", "error") return "error" end -- El Puente del Millón requiere inyección canónica token.set_macro("l__spintent_money_bridge_str", "true") return "success" end local function spintent_gcd_algorithm(val_a, val_b) while val_b ~= 0 do val_a, val_b = val_b, val_a % val_b end return val_a end \end{luapiton} \end{document} How do I define a new language in piton so that it's beautifully colored? I want to copy more or less the style of the lua-widow-control documentation (which is written in ConTeXt).

I have noticed that after a recent TexLive update, the behaviour of the sansmath package has changed. The two example below illustrate: The instructions: \documentclass{article} \usepackage{sansmath} \begin{document} \sansmath This is normal text. \begin{tabular}{ll} One & Two \\ \end{tabular} and the rest of the document follows. \end{document} result in the contents of the tabular environment to be italized (as if it is in a math environment). This is new, unexpected behaviour. If the \sansmath is omitted, then the content of the tabular environment is not placed in italics: \documentclass{article} \usepackage{sansmath} \begin{document} This is normal text. \begin{tabular}{ll} One & Two \\ \end{tabular} and the rest of the document follows. \end{document} I will greatly appreciate any advice on how to revert to the behaviour of \sansmath to what is expected: it impacts only math environments.
