- tikz and pgf not framedby user446112 on July 29, 2026 at 3:55 pm
I'm drawing the graph below using Beamer, but the plot is not framed with the points (1/Pi/2) and (-1,-Pi/2). What’s happening here? My code is: \documentclass{beamer} \usepackage{pgfplots} \usepackage{tikz} \usetikzlibrary{tikzmark,calc,positioning,fit,arrows,shapes,backgrounds,shapes.geometric,arrows.meta,patterns.meta,decorations.pathreplacing} \begin{document} \begin{frame} \begin{center} \begin{tikzpicture}[scale=0.7, samples=100] \draw[-latex,thick] (-3,0) -- (3,0); \draw[-latex,thick] (0,-2.5) -- (0,2.5); \draw [thick](-1,-0.125)--(-1,0.125); \draw [thick](1,-0.125)--(1,0.125); \draw [thick](-0.125,-1.570796327)--(0.125,-1.570796327); \draw [thick](-0.125,1.570796327)--(0.125,1.570796327); \node at (2.5,-0.5) {$x$}; %\draw[-latex,thick] (0,-2) -- (0,3); \node at (-0.5,2.3) {$y$}; \node at (-1,-0.5) {{\scriptsize$-1$}}; \node at (1,-0.5) {{\scriptsize$1$}}; \node at (0.6,-1.570796327) {{\scriptsize$-\frac{\pi}{2}$}}; \node at (-0.4,1.570796327) {{\scriptsize$\frac{\pi}{2}$}}; \draw [thick](-0.125,-1.570796327)--(0.125,-1.570796327); \draw [thick](-0.125,1.570796327)--(0.125,1.570796327); \draw [dotted](1,0)--(1,1.570796327); \draw [dotted](-1,-0.8)--(-1,-1.570796327); \draw [dotted](0,1.570796327)--(1,1.570796327); \draw [dotted](-1,-1.570796327)--(0,-1.570796327); \begin{axis}[smooth,anchor=origin,xmin=-3,xmax=3, domain=-3:3,ymin=-2.5,ymax=2.5,restrict y to domain=-2.5:2.5,axis equal,axis x line=none,axis y line=none,xticklabels=\empty,yticklabels=\empty,samples=100] \addplot[domain=-1:1,blue,line width=2pt] {rad(asin(x))}; \end{axis} \end{tikzpicture} \end{center} \end{frame} \end{document} (compiled through LuaLaTeX).
- How to use csname to reuse command for part and chapter (get \part, \chapter, \thepart, \thechapter)by umarcor on July 29, 2026 at 10:55 am
I'm trying to rewrite the Minimal Working Example (MWE) below to: Use \pctitleformats{part}{blue} instead of \pctitleformats{\part}{part}{blue} Add \partmark{#1}|\chaptermark{#1}. The working reference without auxiliary commands is the following: \titleformat{\part}{\partmark{#1}\Huge\bfseries\color{blue}}{\thepart}{10pt}{#1} \titleformat{\chapter}{\chaptermark{#1}\Huge\bfseries\color{green}}{\thechapter}{10pt}{#1} The naive solution with helper commands is the following: \newcommand*\pctitleformat[4][]{ \titleformat{name=#2, #1}[hang]{\filcenter\bfseries\Huge\color{#4}}{}{0pt}{#3##1} } \newcommand*\pctitleformats[3]{ \pctitleformat{#1}{#2~$|$~}{#3} \pctitleformat[numberless]{#1}{}{#3} } \pctitleformats{\part}{\thepart}{blue} \pctitleformats{\chapter}{\thechapter}{green} However, it is lacking the \*mark{#1}, which the reference has. I got to: \documentclass[twoside,openright]{report} \usepackage{xcolor} \usepackage[explicit,pagestyles]{titlesec} \titleclass{\part}{top} \newcommand*\pctitleformat[5][]{ \titleformat{name=#2, #1}[hang]% {\expandafter\csname #3mark\endcsname{##1}% \filcenter\bfseries\Huge\color{#5}}% {}{0pt}{#4##1} } \newcommand*\pctitleformats[3]{ \pctitleformat{#1}{#2}% {\expandafter\csname the#2\endcsname\relax~$|$~}% {#3} \pctitleformat[numberless]{#1}{#2}% {}% {#3} } \pctitleformats{\part}{part}{blue} \pctitleformats{\chapter}{chapter}{green} \begin{document} \part{Testing} \chapter{Hello} \end{document} I would like to achieve: \documentclass[twoside,openright]{report} \usepackage{xcolor} \usepackage[explicit,pagestyles]{titlesec} \titleclass{\part}{top} \newcommand*\pctitleformat[4][]{ \titleformat{name=\expandafter\csname #2\endcsname\relax, #1}[hang]% {\expandafter\csname #2mark\endcsname{##1}% \filcenter\bfseries\Huge\color{#4} }% {}{0pt}{#3##1} } \newcommand*\pctitleformats[2]{ \pctitleformat{#1}% {\expandafter\csname the#1\endcsname\relax~$|$~}% {#2} \pctitleformat[numberless]{#1}% {}% {#2} } \pctitleformats{part}{blue} \pctitleformats{chapter}{green} \begin{document} \part{Testing} \chapter{Hello} \end{document}
- Missing symbols when using SetSymbolFont to define a sans serif math environmentby Muhannad Al Ayoubi on July 29, 2026 at 10:38 am
I want to write step-by-step explanations in a math textbook I am writing using a serif font. Using the advice in this answer about getting sans-serif math in sans-serif mode, I have experimented with the following MWE: \documentclass{book} \usepackage[scaled=0.9,nohelv]{newtxtext} % Main text font \usepackage[scaled=0.9,vvarbb]{newtxmath} % Main math font \DeclareMathVersion{sans} % Defining sans-serif math font \SetSymbolFont{letters}{sans}{OML}{cmssm}{m}{it} \SetSymbolFont{operators}{sans}{OT1}{xcmss}{m}{n} \SetSymbolFont{symbols}{sans}{OMS}{cmsssy}{m}{n} \SetSymbolFont{largesymbols}{sans}{OMX}{cmssex}{m}{n} \AddToHook{sffamily}{\mathversion{sans}} % Automatically use sans-serif math in sans-serif environments \begin{document} Normal math: $4(x+y)=4x+4y$ \sffamily Sans-serif math: $4(x+y)=4x+4y$ \end{document} Upon compiling (with pdfLaTeX) here is what I get. Notice the missing plus signs and round brackets. How to fix that?
- nameinlink in cleveref not working for custom theorem environmentby Drazer on July 29, 2026 at 9:20 am

- Prevent listings background from changing custom footnoterule backgroundby umarcor on July 28, 2026 at 2:14 pm
In the following Minimal Working Example (MWE), the length of the footnoterule is changed by renewing the command. When listings is used with a coloured background, and if a code block is cut at the end of a page, sometimes the footnoterule gets the background of the code. Note that changing the second lipsum to \lipsum[1][1-7] produces a correct result, while \lipsum[1][1-8] to \lipsum[1][1-11] all incorrectly colour the background of the footnoterule. \documentclass{report} \usepackage{lipsum} \usepackage{xcolor} \renewcommand*{\footnoterule}{ \noindent\rule{14mm}{0.4pt}\hfill\addvspace{.5\baselineskip} } \usepackage{listings} \lstset{ language=C, backgroundcolor=\color{gray!25}, } \begin{document} This is some regular text\footnote{With a footnote.}. \lipsum[1-4] \lipsum[1][1-8] \begin{lstlisting} #include <stdio.h> #include <stdlib.h> int main () { printf("Hello!\n"); return 0; } \end{lstlisting} \end{document}

I have noticed that when using the TeX Gyre Termes Math font, the spacing is too small.

- columns longer than a pageby Sergi Espinosa Polo on July 28, 2026 at 12:12 pm
I have the following question. I have been looking in other places and I can't find anything similar (or I don't know how to look for it). I want to make a table with two columns and one row, so that I can buy a text in medieval Catalan and the Latin translation. I had thought about making a table, but I have a problem. The columns go beyond the page and, then, they appear cut off and do not continue on another page (as would happen with Word). Is there any way to make this document look like the one in Word that I am attaching? Thank you very much This is my code: \documentclass[12pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage{longtable} \usepackage{lipsum} \begin{document} \lipsum[1] \begin{longtable}{|p{0.47\textwidth}|p{0.47\textwidth}|} \hline \lipsum[1] \par \lipsum[1] \par \lipsum[1] \par \lipsum[1] & \lipsum[1] \par \lipsum[1] \par \lipsum[1] \par \lipsum[1] \par \end{longtable} \lipsum[1-2] \end{document}
- Necessarily high-sampled curve in plain TikZby Jasper on July 28, 2026 at 6:34 am
I was making a rational double pendulum in Asymptote: // a rational double pendulum import graph; unitsize(3cm); pair truncated_pi(real t) { real t1 = 3.14 * t; return ( cos(t) + cos(t1), sin(t) + sin(t1) ); } path f = graph(truncated_pi, 0, 314, n=10000); draw(f); I wanted to make it in TikZ, but I am running into the issue of needing a number of samples which is beyond the limit imposed by pgfmath. As some of you may be familiar with, I am very fond of plain TikZ. I would like to see if there are ways to achieve this which are not overly ad hoc. For example, one strategy would be to break the domain into separate regions. How would one draw something like this in the spirit of plain TikZ? \documentclass[tikz]{standalone} \begin{document} \begin{tikzpicture} \draw[ domain=0:314, samples=10000, trig format=rad, declare function={ t1(\x) = 3.14 * \x; x(\x) = cos(\x) + cos(t1(\x)); y(\x) = sin(\x) + sin(t1(\x)); } ] plot ({x(\x)},{y(\x)}); \end{tikzpicture} \end{document}

- Changing the words checked for word repetition in TexStudioby user445996 on July 28, 2026 at 12:01 am
Is there a way to change the kinds of words that the word repetition checker looks for? I like that it will help add variety (e.g. the overuse of very) and find any accidental duplicated words (e.g. "the the tree...") but function words like articles and prepositions can naturally occur frequently (e.g. "the first of the two options..." or "the crown of the king of England"). I dislike seeing the indication that I have a supposed error, and while some can be avoided, not all can be. Is there a way to fix this or is this just something I will have to learn to ignore? It makes me second guess myself unnecessarily.
- Multiple tables with same column widthsby Tristan on July 27, 2026 at 10:50 pm
I am currently writing a linguistic document for which I will need to include multiple tables showing the inflection of various classes of word. I want to be able to have multiple noun declension tables, adjective declension tables, and verb inflection tables throughout the document, and for each table of a given type to have corresponding columns with the same widths (if I overlay one table of a given type over another, the column edges should line up). I.e. I have tables belonging to three types, A, B, & C. Each table of a given type has the same number of rows and columns. I want to ensure that each table of a given type is rendered with the same column widths (ideally this would not have to be set manually by me, but determined based on the widest text placed in a given column in a table of that type). The different types of tables may be interspersed with each other, and tables of a given type might occur in different chapters, so any solution would need to be able to handle that. A minimum example: \documentclass{article} \setlength\parindent{0pt} \begin{document} \begin{tabular}{ r l l} Case & Singular & Plural \\ \hline Nominative & -foo & -bar \\ Accusative & -foo & -bar \\ Genitive & -foo & -bar \\ \end{tabular}\\ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean dictum, mauris id cursus interdum, ligula libero tristique nisi, eget accumsan risus diam et erat. Nulla dignissim neque a accumsan tincidunt. Integer eleifend vel ante porta fringilla. Praesent et venenatis enim, eget vehicula lorem. Curabitur cursus condimentum sagittis. Curabitur eget facilisis massa. Phasellus vitae scelerisque neque. Pellentesque quis magna sed neque mattis tincidunt.\\ \begin{tabular}{ r l l l l l l} Tense & 1sg & 2sg & 3sg & 1pl & 2pl & 3pl \\ \hline Present & -foo & -foo & -foo & -bar & -bar & -bar \\ Past & -foo & -foo & -foo & -bar & -bar & -bar \\ Future & -foo & -foo & -foo & -bar & -bar & -bar \\ \end{tabular}\\ Donec vitae risus id eros consectetur gravida eget nec erat. Fusce condimentum, sapien id vulputate ultricies, felis lacus sagittis elit, sit amet accumsan purus ante dapibus magna. Cras nec quam ac diam dapibus elementum sit amet vitae turpis. Praesent bibendum eleifend imperdiet. Etiam sit amet congue libero. Donec at mauris vitae mi tristique rhoncus sit amet sed turpis. Phasellus sed velit nec sem sodales molestie. Ut gravida, lorem at euismod elementum, lectus massa viverra dui, a ultrices arcu nulla nec arcu. \\ \begin{tabular}{ r l l} Case & Singular & Plural \\ \hline Nominative & -a-really-long-ending & -bar \\ Accusative & -foo & -bar \\ Genitive & -foo & -bar \\ \end{tabular}\\ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean dictum, mauris id cursus interdum, ligula libero tristique nisi, eget accumsan risus diam et erat. Nulla dignissim neque a accumsan tincidunt. Integer eleifend vel ante porta fringilla. Praesent et venenatis enim, eget vehicula lorem. Curabitur cursus condimentum sagittis. Curabitur eget facilisis massa. Phasellus vitae scelerisque neque. Pellentesque quis magna sed neque mattis tincidunt.\\ \begin{tabular}{ r l l l l l l} Tense & 1sg & 2sg & 3sg & 1pl & 2pl & 3pl \\ \hline Present & -foo & -foo & -foo & -bar & -bar & -bar \\ Past & -foo & -foo & -something-that's long & -bar & -bar & -bar \\ Future & -foo & -foo & -foo & -bar & -bar & -bar \\ \end{tabular}\\ \end{document} The first and third table are of the same type, and the second & fourth table are of the same type. Because of this, the two Singular columns of the first and third tables should be of the same width, but because the third table has a longer ending in the table, its Singular column is much longer. Likewise, the 3sg columns of the second and third tables should have the same width, but in the fourth table it's much wider. As seen here, tables of a given type may be separated by other tables (including other tables of a repeating type). There might also be chapter/section/subsection boundaries between the tables of a given type.
- Why does helvratio not work when using newtx?by Muhannad Al Ayoubi on July 27, 2026 at 9:08 pm
It seems passing the option helvratio to \usepackage{newtxtext} does not really change anything. I am writing a textbook and have been experimenting with making the step-by-step explanations sans serif to add some contrast. However the sans serif font is too big, and no matter what I set helvratio to, nothing changes. I thought to try the sans serif font outside of the align environment, but after compiling and recompiling with different helvratios, again nothing changes. So I have resorted to using \scriptsize which I find very inappropriate because it also shrinks the mathematical text (the math included in the first explanation is nonsense, just for the MWE). I am compiling using LuaLaTeX as I believe that is relevant. Here is my MWE: \documentclass[10pt]{book} \usepackage{amsmath} \usepackage[scaled=0.9,helvratio=0.8]{newtxtext} % No matter how I change helvratio, nothing actually changed when I compile. \usepackage[scaled=0.9,vvarbb]{newtxmath} \begin{document} Begin by studying the expression $6x-2$ very well. Notice that it involves two operations: firstly, you multiply by 6, then you subtract by 2. By applying the same steps to the given inequality $x>1$, you can easily prove the statement. \begin{align*} x & > 1 && \text{\scriptsize\sffamily Original condition $x=6$ and $y-7<0$.} &&& \\ 6x & > 6 && \text{\scriptsize\sffamily Multiply each side by 6.} &&& \\ 6x-2 & > 4 && \text{\scriptsize\sffamily Subtract 2 from each side.} &&& \end{align*} $6x-2$ is greater than a positive number, so it must itself be positive. \end{document} (Side note: I am aware it is not good practice to mix sans serif text with serif math, but I could not change the math font only within sans serif environments.) Edit: It seems this problem is only affecting me, and I am not sure why. I have tried recompiling with helvratio=1.5 and helvratio=0.5, and that still results in, as you can see below, the same exact font size. Edit 2: My TeX version is MiKTeX-TeX 4.9 (MiKTeX 26.5).

- System upgrade introduced a new error: \scr@tso@lstlisting@linefill undefinedby Marijn on July 27, 2026 at 2:35 pm
I have a .tex file that used to compile (here is the full file), but since an upgrade of my Debian system, which I assume pulled in some new version of LaTeX packages, it fails to build with this error when I run xelatex on it: ! LaTeX Error: Command \scr@tso@lstlisting@linefill undefined. That looks like some internal issue in koma-script/tocbasic.sty, but my understanding of LaTeX isn't enough to know what to do about it. That sty file looks like it checks for this command being undefined and then defines it, yet here I am with the error. I'd be grateful for a proper solution, of course, but also satisfied with a crude hack to suppress this error so that my pdf file builds again. Edit: This is a minimal reproduction. Seems that both listings and arabxetex have to be present to trigger the error. \documentclass{scrbook} \usepackage{listings} \usepackage{arabxetex} \begin{document} \end{document} Further edit: The suggested fix of adding a line like this... \makeatletter \def\scr@tso@lstlisting@linefill{} \def\scr@tso@lstlisting@pagenumberformat#1{} \makeatother ... avoids this issue, but somehow affects pdfpages in a way that breaks \includepdf.
- Automatic Title Case [duplicate]by M0M0 on July 27, 2026 at 12:48 pm
I found this old question, which shows how to unconditionally capitalize words in section titles. However, title case normally does not capitalize every word, but, i.e., the Chicago Manual of Style recommends to not capitalize articles and conjunctions (among other exceptions). Is there maybe a package that achieves this? It's probably not to hard to code this with latex3, since in the end we have to capitalize every word which is not in some sort of ignore-list, but if someone has already done the work I would be happy to use it. Getting this to work well with toc entries and hyperref, might or might not be difficult.
- I want to do a matrix multiplication (rotation, Rodriguez) on a sphere in Asymptoteby Jasper on July 27, 2026 at 3:03 am
I wrote my question in a comment within the following Asymptote code. My goal is to do a matrix multiplication (rotation, Rodriguez) on a sphere I made in Asymptote, without changing the camera. Rodriguez rotation is angle by axis, as opposed to Euler, which is by standard axes in a specific order. Also, any explanation as to why this is rather slow? I think it would be even clearer to pose this as a multiplication on an arbitrary triple. import three; unitsize(5cm); currentprojection=orthographic(1,2,3); /* draw((0,0) -- (1,1)); label("\(a\)", (0,1), (-1,-1)); draw((0,0)..controls (0,1) and (1,1)..(1,0)); */ triple SP(triple point){ return ( point.x / (1 - point.z), point.y / (1 - point.z), 0 ); } triple ISP(triple point){ real temp = point.x^2 + point.y^2; return ( 2 * point.x / (1 + temp), 2 * point.y / (1 + temp), (-1 + temp) / (1 + temp) ); } for(int i=-10; i<=10; ++i){ for(real j=-10; j<=10; j += 0.1){ if(j!=10){ draw(ISP((i,j,0)) -- ISP((i,j+1/10,0))); draw(ISP((j,i,0)) -- ISP((j+1/10,i,0))); /* My motivation in asking this question is to perform a general axis-angle (Rodriguez) transformation to this Riemann sphere, without changing the camera projection.

I have searched this question, and have found so many, many different answers (a number of which I have tried unsuccessfully), that I feel as if it is the same as having no answer. What I am trying to do is fairly simple. I want every "normal" paragraph to be automatically and consecutively numbered through a document, eg, [1], [2]. By "normal" paragraph, what I mean is what would normally be a plain, unadorned paragraph from the body of a document that would be entered in most cases as plain text after a blank line. For example, my LaTeX source would look like this: \documentclass{article} \begin{document} \section{Section Heading} This is the first paragraph of my first section. It should have [1] at the beginning. This is the second paragraph of my first section. It should have [2] at the beginning. Following is a bullet list which should not be numbered: \begin{itemize} \item First list item \item Second list item \end{itemize} This is the third paragraph of my first section, should have [3] at the beginning. \subsection{Subsection Heading} This is the first paragraph of my first subsection. It should have [4] at the beginning. Here is a quote which should not be numbered: \begin{quote} This paragraph is a quotation from somewhere else. \end{quote} This is the next paragraph of my first subsection. It should have [5] at the beginning. \section{Another Section} This is the first paragraph of my second section. It should have [6] at the beginning. And so on. \end{document} Some of the code I've tried numbered EVERYTHING, including title pages, TOC, footnotes, captions etc. etc. However, I ONLY want the regular paragraphs numbered this way. What I want the output to look like is this: Section Heading [1] This is the first paragraph of my first section. It should have [1] at the beginning. [2] This is the second paragraph of my first section. It should have [2] at the beginning. Following is a bullet list which should not be numbered: First list item Second list item [3] This is the third paragraph of my first section. Subsection Heading [4] This is the first paragraph of my first subsection. It should have [4] at the beginning. Here is a quote which should not be numbered: This is the quotation. [5] This is the next paragraph of my first subsection. It should have [5] at the beginning. Another Section [6] This is the first paragraph of my second section. It should have [6] at the beginning. And so on. An example of what I want is Canadian court decisions, which usually look like this: https://www.canlii.org/en/on/onscdc/doc/2026/2026onsc3525/2026onsc3525.html If there is a simple answer to this that I have missed, would be much appreciated! Thanks
- Does `odt` creation with` tex4ht` resp. `make4ht` go with `lstinputlisting`?by user2609605 on July 26, 2026 at 10:44 am
The following is an MWE, or a MnWE test.tex: \documentclass{article} \usepackage{listings} \begin{document} This is \texttt{test.tex} \lstinputlisting{./test.tex} \end{document} Compiling this with make4ht -l -f xhtml test works without warning or error. In contrast, make4ht -l -f odt test yields $ make4ht -l -f odt test [STATUS] make4ht: Conversion started [STATUS] make4ht: Input file: test [ERROR] htlatex: Compilation errors in the htlatex run [ERROR] htlatex: Filename Line Message [ERROR] htlatex: ./test.tex ?

I don't know whether this is the proper place or not. What I can tell is, that applying this patch, the result is [STATUS] make4ht: Conversion started [STATUS] make4ht: Input file: test [WARNING] domfilter: XML DOM parsing of test.4oo failed: [WARNING] domfilter: ...ive/2025/texmf-dist/tex/luatex/luaxml/luaxml-mod-xml.lua:175: Unbalanced Tag (/text:p) [char=2732] [WARNING] domfilter: HTML DOM parsing OK, DOM filters will be executed --- xtpipes error 32 --- Missing 4xt script file name [WARNING] xtpipes: Xtpipes failed [WARNING] xtpipes: Trying HTML tidy [STATUS] make4ht: Conversion finished which means that the error disappeared but the warning is still unresolved. My LibreOffice opens and shows a fairly good result. Nevertheless, if I unzip test.odt, and check xmllint settings.xml and accordingly with meta.xml, the xml tags are unbalanced. A last observation: If I use the according lstlisting environment instead of the \lstinputlisting macro as so: \documentclass{article} \usepackage{listings} \begin{document} test %\lstinputlisting{./test.tex} \begin{lstlisting} \documentclass{article} \usepackage{listings} \begin{document} test %\lstinputlisting{./test.tex} ... \end{document} \end{lstlisting} \end{document} all works fine, even without the patch.
- Fonts with good coverage of archaic Chinese charactersby richard on July 26, 2026 at 12:28 am
I'm trying to typeset an English document which contains the following text: The first of these Chinese characters is really problematic, and I've yet to identify a font which contains it. It is Unicode code point U+2B4DE (𫓞), which is an obscure, archaic character in the CJK Unified Ideographs Extension C block. It's normally replaced with 林 (U+6797) today, but I want to use the original character at least on the first use. Is anyone aware of a font that contains this sort of obscure characters? I typically use Noto Serif SC (or TC) when embedding fragments of Chinese in English text, and it's pretty good, but it doesn't seem to support this character. If not, is there any way of assembling the character manually from the 金 signific and 林 and 㐭 radicals which make it up, either in LaTeX or, possibly better, at a Unicode level using combining characters somehow? This question is not a duplicate of ‘Why doesn't my Chinese character display properly?’. I know why it doesn't display: my font doesn't support it. I'm also familiar with the solutions to that question: namely, to try a different font, in one of several different ways. What I'm looking for is either (a) a recommendation for a font that has sufficient coverage, or (b) a technique for composing the character manually from its individual radicals. Neither of those topics are addressed in that question.
- ConTeXt: is option `bodypartlabel` deprecated?by Akira on July 25, 2026 at 11:28 am

- Is there a built-in mechanism in plain TikZ to cache intermediate calculations locally within a plot expression?by Jasper on July 25, 2026 at 5:35 am
Is there a built-in mechanism in plain TikZ to cache intermediate calculations locally within a plot expression? I mean I could just use a foreach loop and pgfmathsetmacro, but that's quite intensive. Is this built in to plot? If not, should/could it be? \documentclass{article} \usepackage{tikz} \begin{document} \tikz \draw[domain=0:1] plot ( \x, { (\x-2)^2 % there is an (\x-2) term here - (\x-2)^3 % and it is duplicated here } ) ; \end{document}
- tcolorbox vertical alignment in-line slightly offby anak on July 24, 2026 at 3:34 pm
I am encountering issues when trying to make an environment with the tcolorbox package that creates a vertically-aligned in-line box enclosing an itemize environment. The purpose was to mimic an \fbox around an itemize in a minipage (hence the prescribed width). Below is code for a MWE: \documentclass{standalone} \usepackage{tcolorbox} \usepackage{enumitem} \newenvironment{mybox}[1] { \begin{tcolorbox}[ on line, left=0em, right=0em, top=0em, bottom=0em, box align=center, width=#1, ] \begin{itemize}[ nosep, leftmargin=*, labelsep=0em, ] }{ \end{itemize} \end{tcolorbox} } \begin{document} This text is slightly above the centre of the box \begin{mybox}{3cm} \item True \item False \end{mybox} \end{document} However, there appears to be some misalignment with the outside text, as if there is additional space placed above the tcolorbox. Compare with the minipage method: \fbox{\begin{minipage}{3cm} \begin{itemize}[ nosep, leftmargin=*, labelsep=0em, ] \item True \item False \end{itemize} \end{minipage}}
- tkz-euclide: Ignore undrawn points for bounding boxby Nick A. on July 24, 2026 at 1:34 pm
I'm using tkz-euclide to draw the following diagram, which is not properly centered: \documentclass{article} \usepackage{tikz} \usepackage{tkz-euclide} \begin{document} \begin{tikzpicture} \tkzDefPoints{0/0/A, 5/0/B} \tkzCalcLength(A,B) \tkzGetLength{dAB} \tkzDefCircle[R](A, 0.4*\dAB) \tkzGetPoint{P1} \tkzInterLC(A,B)(A,P1) \tkzGetPoints{}{C} \tkzDefCircle[R](B, 0.4*\dAB) \tkzGetPoint{P2} \tkzInterLC(A,B)(B,P2) \tkzGetPoints{D}{} \tkzInterCC(A,C)(C,A) \tkzGetPoints{E}{} \tkzInterCC(D,B)(B,D) \tkzGetPoints{F}{} \tkzInterLL(A,E)(B,F) \tkzGetPoint{G} \tkzDrawSegment[thick](A,B) \tkzDrawArc[gray, delta=10](A,C)(E) \tkzDrawArc[gray, delta=10](B,F)(D) \tkzDrawArc[gray, delta=10](C,E)(A) \tkzDrawArc[gray, delta=10](D,B)(F) \tkzDrawSegments[gray, add=0 and .1](A,G B,G) \tkzDrawSegments[thick, blue](A,G B,G) \tkzLabelPoint[below left](A){$A$} \tkzLabelPoint[below right](B){$B$} \tkzLabelPoint[below left](C){$C$} \tkzLabelPoint[below right](D){$D$} \tkzLabelPoint[above left](E){$E$} \tkzLabelPoint[above right](F){$F$} \tkzLabelPoint[above](G){$G$} % \tkzDrawPoints(P2) % \draw[red] (current bounding box.south west) rectangle (current bounding box.north east); \end{tikzpicture} \end{document} Uncommenting the code at the bottom shows the issue is with the point P2: It's only used for calculation and not drawn, but the bounding box is drawn to include it anyway, pushing the diagram left. Is there a way to instruct tikz to ignore this point so the diagram is centered appropriately? Is there a better way to use tkz-euclide to avoid this issue?
- what is the meaning of return codes of tlmgr?by user2609605 on July 23, 2026 at 8:28 pm
I wrote some install script for texlive using of course tlmgr under the hood. Nowhere I can find a documentation comprising return values also. I tried to analyze the script.. but was not really sure about the results. A link to documentation would be helpful since maybe even tlmgr may evolve. Reviewing the code, roughly speaking, the return value must be read in terms of bits $F_WARNING = 1 (Bit 0) $F_ERROR = 2 (Bit 1) $F_NOPOSTACTION = 4 (Bit 2) I think in most cases $F_ERROR bit set signifies an error, accordingly $F_WARNING set indicates a warning and $F_NOPOSTACTION... well I cannot figure out what a post action is. I am not quite sure about my analysis is really valid in any case and I dont know what a postaction is. Maybe someone reads this who is able to add a piece of documentation.

- titletoc: subpart causes overfull hboxby grenville on July 22, 2026 at 8:30 pm
I am using titlesec/titletoc to give my article a section type \subpart between \section and \part. But there's an alignment problem with the page number in the table of contents, which makes three-figure page numbers cause an overfull hbox. Would be very grateful for some assistance. Attempted MWE below. N.B. I'm new to titlesec, and lifted the relevant code from this answer. \documentclass[draft]{article} \usepackage{titlesec} \usepackage{titletoc} \titleclass{\subpart}{page}[\part] \newcounter{subpart} \renewcommand{\thesubpart}{\Alph{subpart}} \newcommand{\subpartname}{Subpart} \titleformat{\subpart}[display]{\normalfont\LARGE\bfseries}{\subpartname~\thesubpart}{1pc}{} \titlespacing{\subpart}{0pt}{0pt}{0pt} \makeatletter \def\toclevel@part{-1} \def\toclevel@subpart{0} \makeatother \titlecontents{subpart}[0pt]{\addvspace{1pc}\normalfont\large\bfseries}% {\thecontentslabel\enspace ---\enspace}% {}{\hspace{0pt plus 1fill}\contentspage} \begin{document} \tableofcontents \setcounter{page}{100} \part{This is a part} \subpart{This is a subpart} \end{document}
