I maintain, expand, and refine a personal template that has become quite complex by now. Due to an issue in the 2024 snapshot, I skipped that version and would now like to move to the current 2025 release. When doing so, I encounter two warnings: Command \showhyphens has changed. Package tracklang Warning: No datatool support for dialect ngerman on input line 9908. I managed to reduce the behaviour to this short MWE, so I assume the warnings are not caused by the many new definitions and adjustments in my full template. I rely on both packages: % Overleaf, pdfLaTeX, TeX Live Version 2025 \documentclass[ngerman]{standalone} \usepackage{microtype}% "\showhyphens has changed." \usepackage{babel} \usepackage{datatool}% "No datatool support for dialect ngerman." \begin{document} MWE \end{document} From what I have found so far, the microtype message seems to be an informational notice rather than an actual warning. I also assume that the missing datatool-dialect support can be ignored, because I only sort my own labels, which do not include country‑specific symbols or similar characters. Does switching to the 2025 version offer any advantages (besides updated packages such as fontawesome7 instead of fontawesome5) that I would not get with the 2023 snapshot? I read that microtype has been improved further. I would prefer not to add a patch or something similar to my template just to address these warnings. If such a change becomes necessary, that would be a follow up question.

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. It should look like I tried this code: \documentclass{article} \usepackage{fontspec} \usepackage{xcolor} \usepackage{luacolor} \usepackage[bidi=basic]{babel} % Setup Arabic language \babelprovide[import, main]{arabic} % THE FIX: Use Renderer=Node instead of Harfbuzz \babelfont{rm}[Renderer=Node]{Amiri} % 1.

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

I apologize for asking what appears to be such a simple question, but would you please tell me what I'm missing to get the body matter to start on the next page immediately after the front matter ends? This example makes it a right-hand page, inserting a blank page on the left; and no option I have tried, thus far, changes that.

how to create a calendar like the attached photo. in particular how to: combine days like may 24/31 so that one month's calendar always fits on 5 rows, and how to put items (e.g. mini calendar for previous and successive months, photo, or lunar phases) in the boxes that aren't days

I am using win 11, VS Code. My full LaTeX Workshop configuration contains multiple recipes, but the relevant part looks like this (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" ] }, { "name": "cleaner", "command": "latexmk", "args": [ "-c", "%DOC%" ] } ], "latex-workshop.latex.recipes": [ { "name": "latexmk → nomencl → latexmk → latexmk cleaner", "tools": [ "latexmk", "makenomenclature", "latexmk", "cleaner" ] } ], "latex-workshop.latex.recipe.default": "latexmk → nomencl → latexmk → latexmk cleaner", "latex-workshop.latex.autoBuild.run": "never", } After compilation, a typical project directory contains (without -c or -C): aromatic.eps bib.bib main.aux main.bbl main.bcf main.blg main.dvi main.fdb_latexmk main.fls main.ilg main.log main.nlo main.nls main.out main.pdf main.ps main.run.xml main.synctex.gz main.tex With -c: aromatic.eps bib.bib main.bbl main.dvi main.nlo main.nls main.pdf main.ps main.synctex.gz main.tex With -C: aromatic.eps bib.bib main.bbl main.nlo main.nls main.tex I would like a cleaning setup where only these files remain: *.tex *.pdf *.bib *.eps *.png/*.jpg (other img format) Everything else should be removed. Is it possible to configure latexmk to clean files using a whitelist approach (keep only specific extensions), instead of relying on the default -c / -C behavior? Additionally, I have multiple subdirectories (e.g., chapters/, figures/, etc.) that also contain auxiliary files such as .aux, so delete those files as well. I only want this for archiving, and this question occurred to me - whether it would be feasible.

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!

I am working on Overleaf (using XeLaTeX compiler) and I am trying to use both the fontspec package (to use a different font) and the realhats package (to give my symbols "real hats"). However, when I activate fontspec, it turns all the realhats back into "regular hats." This happens even when I don't change the font, just when I activate the fontspec package. Example 1: Realhats works \documentclass[12pt]{article} \usepackage[margin=1in]{geometry} \usepackage{amsmath,amssymb,amsthm} % maths packages \usepackage{amsfonts} \usepackage{graphicx} % Required for inserting images \usepackage{xcolor} \usepackage{tikz-cd} % commutative diagrams %\usepackage{fontspec} \usepackage{realhats} \usepackage{etoolbox,xspace,bbm} \usepackage{hyperref} \begin{document} %\setmainfont{ComicSansMS3.ttf} Random text $\hat{p}.$ \end{document} Example 2: Realhats doesn't work (only change is uncommenting fontspec) \documentclass[12pt]{article} \usepackage[margin=1in]{geometry} \usepackage{amsmath,amssymb,amsthm} % maths packages \usepackage{amsfonts} \usepackage{graphicx} % Required for inserting images \usepackage{xcolor} \usepackage{tikz-cd} % commutative diagrams \usepackage{fontspec} \usepackage{realhats} \usepackage{etoolbox,xspace,bbm} \usepackage{hyperref} \begin{document} %\setmainfont{ComicSansMS3.ttf} Random text $\hat{p}.$ \end{document} Any ideas on how to fix this? Or, if it cannot be fixed, how I can get both the font change and have real hats? Thank you, have a nice day.

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}

I used AI to create this table from Tony Records Guided notes. I was hoping to drag and drop code for my notes today, but there are several errors that I can't locate. Also, column on left is not aligned with right. Any help is appreciated. \documentclass{article} \usepackage[margin=1in]{geometry} \usepackage[most]{tcolorbox} \usepackage{tabularray} \usepackage{amsmath} \usepackage{xcolor} % Custom Colors from the image \definecolor{headerpurple}{RGB}{102, 45, 145} \definecolor{bodyblue}{RGB}{214, 230, 247} \definecolor{benefitgold}{RGB}{255, 242, 204} \definecolor{drawbackorange}{RGB}{248, 203, 173} \begin{document} \begin{tcolorbox}[ enhanced, sharp corners, boxrule=1.5pt, colframe=black, colback=white, left=0mm, right=0mm, top=0mm, bottom=0mm, boxsep=0pt, title=\textbf{\large Defining a Sequence}, colbacktitle=headerpurple, toptitle=2mm, bottomtitle=2mm, center title ] \begin{tblr}{ colspec = {X[l,m]X[l,m]}, stretch = 1.2, vlines = {0.5pt, black}, % Vertical line between columns hlines = {0.5pt, black}, % Horizontal lines between rows column{1,2} = {leftsep=8pt, rightsep=8pt, topsep=6pt, bottomsep=6pt}, row{1} = {bg=headerpurple, fg=white, font=\bfseries, halign=c}, row{2} = {bg=bodyblue}, row{3} = {bg=benefitgold}, row{4} = {bg=drawbackorange}, } % Row 1: Headers Recursive (Implicit) Definition) & Explicit Definition \\ % Row 2: Main Content { \textbf{Note:} Each term in the sequence is three more than the preceding term.

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 tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table.

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)

I'm writing a document in French, and I'm including subfiles using the command \input. I'm using the extension LTeX, which is a spell check extension, for LaTeX (and other format) document, in order to spot errors in my document. In the main document, the French language is well detected, and the mistakes made are correctly displayed. However, in the other file included, the mistakes are not spotted at all, despite the presence of the flag setting the language to French. If I remove this flag, the errors are indeed spotted, but regarding the English language... Here is the main file \documentclass[10pt]{article} \usepackage[french]{babel} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \begin{document} bonjour, ceci est un texte en francais. % Error spotted : missing upper case B, and typo in the word francais \input{file2} \end{document} and here is the file2.tex % LTeX: language=fr-FR et ceci est le sous-fcihier. % Error that should be spotted : missing upper case E and typo in the word fcihier

I have code snippets in my document, which I present using the listings package. Specifically, I want the code to be in \ttfamily. However, it seems that the lstlisting environments “leak” into the page headers (in this case, fancy headers): In the header, the text should not be in ttfamily, but in normal small caps. I tried adding \normalfont in \lstset{basicstyle= and also in the header definition \fancyhead[LO], but it didn't change anything. How can I fix this?

When typing a document in Thai with babel (using XeLaTeX via MikTeX), sometimes it outputs with these spaces between words, for example: MWE: \documentclass[12pt,a4paper]{article} \usepackage[no-math]{fontspec} \usepackage[thai,provide=*]{babel} \babelfont[thai]{rm}[Scale=1.33333]{TH Sarabun New} \renewcommand\baselinestretch{1.4} \begin{document} เดิมแผ่นดินเมืองจีนทั้งปวงนั้น เปนสุขมาช้านานแล้วก็เปนศึก ครั้นศึกสงบแล้วก็เปนสุข มีพระมหากษัตริย์ทรงพระนามพระเจ้าจิวบูอ๋อง แลพระวงศ์ได้เสวยราชย์ต่อ ๆ ลงมาเปนหลายพระองค์ ได้ความสุขมาถึงเจ็ดร้อยปี จึงมีผู้ตั้งแขงเมืองถึงเจ็ดหัวเมือง ครั้งนั้นพระเจ้าจิ๋นอ๋องได้เสวยราชย์ในเมืองจิ๋นก๊กให้ไปตีเอาหัวเมืองทั้งเจ็ดนั้น เข้าอยู่ในอาณาจักรพระเจ้าจิ๋นอ๋องทั้งสิ้น ครั้นอยู่มาพระเจ้าจิ๋นอ๋องเสียแก่ฮั่นฌ้อ แล้วฮั่นโกโจกับฮั่นฌ้อรบกัน จึงได้ราชสมบัติแก่ฮั่นโกโจ ฮั่นโกโจแลพระราชวงศ์ได้เสวยราชสมบัติต่อ ๆ มาในแผ่นดินจีนนั้นถึงสิบสององค์ มีขุนนางคนหนึ่งชื่ออองมังเปนขบถชิงเอาราชสมบัติได้ เปนเจ้าแผ่นดินอยู่สิบแปดปี แล้วจึงมีหลานพระเจ้าฮั่นโกโจชื่อฮั่นกองบู๊จับอองมังฆ่าเสียชิงเอาราชสมบัติได้เสวยราชย์สืบวงศ์มาสิบสององค์ พระองค์ได้เสวยราชย์ที่สุดนั้น ทรงพระนามพระเจ้าเหี้ยนเต้ จึงแตกเปนสามเมือง ภาษาจีนเรียกว่า สามก๊ก \end{document} How to stop LaTeX from doing this?

I would like to terminate a quantum wire in Quantikz with an "X" drawn over the rightmost end. (I don't want to put the "X" in a box, because that would look like a Pauli X-gate.) The best way that I've found to do this is to with the swap{} command, like this: \documentclass{article} \usepackage{tikz} \usetikzlibrary{quantikz} \begin{document} \begin{quantikz} \lstick{} & \swap{} \end{quantikz} \end{document} This isn't bad, but the wire extends a little bit past the center of the "x". Is there any way to get the wire to terminate right at the cross of the "x"?

I want to define my own style of Python, so I write \documentclass{article} \usepackage{listings, xcolor} \lstset { basicstyle = \ttfamily\small, frame = leftline, framerule = 1pt, } \lstdefinelanguage{python}{ morekeywords = {python, red}, keywordstyle = {\bfseries\color{red}}, rulecolor = {\color{red}}, } \begin{document} \begin{lstlisting}[language=python] python, red \end{lstlisting} \end{document}% after compiling with texlive 2025, I got: It did not work. I thought it might be the problem with the default settings of listings.sty package, i.e. lstlang1.sty. However, I can change the style of matlab language: \documentclass{article} \usepackage{listings, xcolor} \lstset { basicstyle = \ttfamily\small, frame = leftline, framerule = 1pt, } \lstdefinelanguage{python}{ morekeywords = {python, red}, keywordstyle = {\bfseries\color{red}}, rulecolor = {\color{red}}, } \lstdefinelanguage{Matlab}{ morekeywords = {Matlab, lime}, keywordstyle = {\bfseries\color{lime}}, rulecolor = {\color{red}}, } \begin{document} \begin{lstlisting}[language=python] python, red \end{lstlisting} \begin{lstlisting}[language=Matlab] Matlab, lime \end{lstlisting} \end{document}% The output is: I wonder why it happened and how I can actually change the style of "python" language. EDIT: I found that this does not work only on TexLive 2025; my version of listings is 76899, and it's cat-version is 1.11b. If I compile this file with 1.10a and TexLive 2024 on Overleaf, all things worked well. EDIT: I found that listings package is insensitive to the language name, Python, python, and PYTHon point to the same language

Foreign words or phrases inside a mostly monolingual document should usually be displayed in italic. How can this be achieved automatically using babel? I have produced the following code: \documentclass{article} \usepackage{lipsum} \usepackage[french, british, italian]{babel} % Font for the main language \babelfont{rm}{ebgaramond} % Font for foreign languages, inverting roman and italic \babelfont [french, british]{rm}{ebgaramond-Italic} \begin{document} MAIN LANGUAGE \lipsum[1] \vspace{1em} FOREIGN LANGUAGE \foreignlanguage{british}{\lipsum[1]} \end{document} However, I can see some problems in my approach: If I define new features for the font (ligatures, character variants...) I must repeat them for both the main and the foreign font; If I add new languages I must remember to add them to the list of foreign languages to which the italic must be applied. I am quite sure that the amazing babeltransform can easily make it more automatic.

Can someone suggest a method to have Roman (upright) capitals in italic texts, in the style of Aldus Manutius and of the early Renaissance books? I believe it could probably be done with the lua.otf.font.handler but I don't know where to start. Also, I think at least two aspects need to be kept in mind: Efficiency: the approach should not be too heavy, in order to be usable also for large documents with many paragraphs in italics; Kerning: it will probably be required to define new kerning pairs for many (or every) capital, and I expect this to be done manually depending on the font used in the document. As an example to test this: \documentclass{article} \usepackage{lipsum} \usepackage{ETbb} % A font in the style of Aldus Manutius \begin{document} A B C D E F G H I J K L M N O P Q R S T U V W X Y Z \vspace{1em} \textit{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \vspace{1em} \lipsum[1] \vspace{1em} \textit{\lipsum[1]} \end{document} Every suggestion, even if not a complete answer, is very appreciated.

I'm trying to make a title with \newtheorem{case}{Caso} (My code is in Portuguese-Portugal) and it outputs Caso X. "X" being the next number. So here is the thing, I actually need to reset the "X" value, and I have tried the [theorem] parameter, but it doesn't work for me so can anyone help? Here is my code: \documentclass[12pt]{report} \usepackage[]{amsmath,amsthm,amssymb,amscd} \usepackage[a4paper,margin=25mm]{geometry} \usepackage{babel} \usepackage{pgfplots} \usepackage{multirow} \usepackage{booktabs} \usepackage{framed} \newtheorem{case}{Caso} \begin{document} \begin{case} Não conhecemos a distribuição de $X_1$ ou $X_2$, mas os tamanhos das amostras não apresentão assimetrias exageradas. \end{case} \begin{case} % Some text here % \end{case} % Reset the X value % \begin{case} % More text here, but with it saying "Caso 1." % \end{case} \end{document} If you want something else please tell me.

How can I calculate or approximate the intersection(s) or lack thereof of a line and an exponential curve.
