In texdoc libertinus-otf, page.11, sec.3.4, we know that: If you do not like the monofont, you can use the package option mono=false, then no mono font is defined and the default Latin Modern Mono will be used unless no one other will be defined. However, on my windows 11, it gives another result: \documentclass{article} \usepackage[mono=false]{libertinus-otf} % \renewcommand{\ttdefault}{lmtt} \begin{document} ABC \texttt{abc} \end{document} That was AnonymousPro but not latin modern typewriter(lmtt)...? Any suggestions on the reason? Either \usepackage[tt=false]{libertine} or \renewcommand{\ttdefault}{lmtt} works...

I want to output text only, but all the text formatting commands are not executed\not expanded. Also, the text formatting commands are also not printed. I'm familiar with the \verb command, the verbatim environment and similar commands, but these are not what I want. MWE \documentclass{book} \newcommand*{\myText}{This is any text. It contains a \textbf{bold} command. It may also contain other text formatting commands, or \hspace{1.0in} spacing commands.} \begin{document} \myText %This will print the text with the formatting commands. %But I want to have a new command \myOutputTextNoFormat so that when I execute %\myOutputTextNoFormat{\myText}, the following ``text only'' is printed: %This is any text.

I recently upgraded to MacOS27. Compiling in TeXShop no longer works -- the console is completely blank and the PDF isn't rendered. I'm running TeXShop 5.57. The path settings appear to be correct (/Library/TeX/texbin) and I've also updated XCode to 27.1. Any suggestions on what to try?

Question I'm not sure what the correct way to put main body text (including maths and display maths) inside a box - such that the box can flow across a page break, and have the broken edge indicate the content is not finished but continues on the next page (eg by not having a line for that edge). What I have tried I tried Insert->Box. This I think uses a minipage internally. If the box contents don't fit on the remaining page space, the entire box is moved to a new page. I tried editing the box properties but Simple Frame, Page Breaks is greyed out. I tried importing tfe fancy coloured boxes package by Document->Settings->Modules->Boxes->Fancy Coloured Boxes. This gives me a new Insert->Box->Shaded Background option and in there I can just set the frame to have a colour and not the background. I also set Inner Box: None. The settings now allow me to choose Simple Frame, Page Breaks. This now enables page breaks on the box contents but the bottom of broken box (and the top of the continued box) are still solid. The image below illustrates what I am trying to achieve. I've seen people refer to framed as a better option but this seems to require preamble and ERT, which I want to avoid. I wan to use as much standard lyx GUI as possible. I'm using Lyx 2.5.3 on MacOS 15 and the 2026 edition of MacTex.

First a minimal working sample is as follows. \documentclass[fontset=fandol]{ctexbook} \setCJKfamilyfont{fandolkaiti}{FandolKai-Regular.otf}% \newcommand{\kaiti}{\CJKfamily{fandolkaiti}} \usepackage{babel} \babelprovide{russian}% \babelfont[russian]{rm}[Scale=MatchUppercase, Script=Cyrillic, Renderer=Harfbuzz, ItalicFont={NewCM10-Italic.otf}, BoldFont={NewCM10-Bold.otf}, BoldItalicFont={NewCM10-BoldItalic.otf}]{NewCM10-Regular.otf} \usepackage{fancyhdr} \fancypagestyle{main}{% \fancyhf{} \fancyhead[LE]{\kaiti\small\thepage\hspace{4em}\leftmark}% \fancyhead[RO]{\kaiti\small\rightmark\hspace{4em}\thepage}% \renewcommand{\headrule}{}% } \begin{document} \pagestyle{main} \chapter{测试文字Test} \section{依然是测试文字} {\kaiti 第一章\quad 测试文字TEST}%\kaiti affects only on Chinese \clearpage 文字 \end{document} As you see, to make the header be in Chinese regular script font (Kaiti; only Chinese texts turn to be the font while English texts keep in default fonts), I defined \kaiti. But when I set \babelfont, \kaiti doesn't work anymore in the header although it still works well in the main body of the document. Compare 第一章 测试文字TEST in the main body of the document and the header. They should be the same while in fact not. Then how to solve the conflict? Note that \itshape works well but it works both on Chinese and English texts.

For an exercise, I wrote a reaction suite with chemfig (by the way, it is perhaps not the most suitable tool).

I'm trying to typeset a project using TeX Gyre Pagella (Math). When I try to produce the limit of a function (see MWE), the space between the "lim" and "f" is far too small. Is there a way to increase this space (for all instances of the limit) outside of manually using \, or other spacing commands? For transparency, I'm using XeLaTeX on Overleaf. I don't know whether a local instance of XeLaTeX will produce the same result. \documentclass{minimal} % \usepackage{amsmath} \usepackage{unicode-math} \setmainfont{TeX Gyre Pagella} \setmathfont{TeX Gyre Pagella Math} \begin{document} We say that \begin{equation*} \lim_{x \to a} f(x) = L \end{equation*} if, insert $\varepsilon$ and $\delta$ definition here. \end{document} Interestingly, newpxmath (which apparently loads Pagella) does not have this problem. The image comes from the code below: \documentclass{article} % \usepackage{newtxmath} \usepackage{newpxmath} \begin{document} % With \texttt{newtxmath} With \texttt{newpxmath} \begin{equation*} \lim_{x \to a} f(x) = L \end{equation*} \end{document} (But I have other opinions about it which are not within the scope of the question anymore.) Similar results are produced using TeX Gyre Termes Math and newtxmath (see images).

I would like to compile the following simple example of a LaTeX document with the tool arara, taken from its quickstart guide: % arara: pdflatex \documentclass{article} \begin{document} Hello world! \end{document} Let us refer to this file as main.tex and locate it in the directory project/src. When I now call arara from directory project/src, everything works as expected: >> arara main.tex __ _ _ __ __ _ _ __ __ _ / _` | '__/ _` | '__/ _` | | (_| | | | (_| | | | (_| | \__,_|_| \__,_|_| \__,_| Processing "main.tex" (size: 94 B, last modified: 2026-10-22 14:02:02), please wait.

Now, suppose there is another directory project/out. I want pdflatex to put all the output (and auxiliary) files into this directory. Thus, I need to use the -output-directory flag. Moreover, I want to call arara from directory project.

I am using the siunitx package and want to format a measurement with its uncertainty, for example: 31.76 ± 0.34 g I have tried the following: \SI{31.76(34)}{\gram} However, this produces (31.76 ± 0.34) g, with the uncertainty enclosed in parentheses. I have also tried: \SI{31.76 +- 0.34}{\gram} but this produces (31.76 ± 0.34) g, with the entire expression enclosed in parentheses. How can I use siunitx to produce 31.76 ± 0.34 g without parentheses around either the uncertainty or the entire expression? I would prefer a solution that uses siunitx commands rather than manually formatting the units.

My example below: \documentclass{article} \usepackage{multicol} \begin{document} \begingroup \parindent=0pt \interlinepenalty=10000 \begin{multicols}{2} A\\ B\\ C \par \rule{.7\linewidth}{.6pt}\\ D\\ E\vskip23pt F \end{multicols} \endgroup \end{document} results in the following: But if I change \vskip23pt to \vskip24pt, then the column break will shift position, and the result will be: I did all this just to show that \interlinepenalty=10000 is working correctly—that is, there is no page break between the \rule and the letter “D”. The problem arises when the code becomes a bit more complicated: \documentclass{article} \usepackage{multicol} \begin{document} \def\x#1{\par{\centering \rule{.7\linewidth}{.6pt}\\ #1\par}} \begingroup \parindent=0pt \interlinepenalty=10000 \begin{multicols}{2} \x{A\\ B\\ C} \x{D} \x{E} \x{F} \end{multicols} \endgroup \end{document} Which generates: My question is: why did a column break occur between \rule and the letter “D” in this case?

I came across an inconsistent vertical spacing if a tblr with long option directly follows a section. If due to other generic content there is a pagebreak before the section, the vertical spacing between tblr and the section title can get screwed up. Weirdly, this is only true for a rather specific value for the vspace in the MWE. If it's at 15 cm, everything fits nicely on one page and the spacing is correct. If it's set to 18 cm or more, again the spacing on the next page is correct. Is this a bug I should report, or is this solvable? \documentclass[a4paper,11pt]{article} \usepackage{tabularray} \begin{document} \section*{Some Section} \begin{tblr}[long,label=none,presep=0mm,headsep=0pt,footsep=0pt]{width=\linewidth,colspec={l|X},stretch=0,rowhead=0,rowfoot=0} {Bla} & {Blub}\\ \end{tblr} \section*{Another Section} \begin{tblr}[long,label=none,presep=0mm,headsep=0pt,footsep=0pt]{width=\linewidth,colspec={l|X},stretch=0,rowhead=0,rowfoot=0} {Bla} & {Blub}\\ \end{tblr} \vspace{16cm} %try 15cm (fits on same page without issue) and 18cm (next page, no issue) \section*{Yet Another Section} \begin{tblr}[long,label=none,presep=0mm,headsep=0pt,footsep=0pt]{width=\linewidth,colspec={l|X},stretch=0,rowhead=0,rowfoot=0} {Bla} & {Blub}\\ \end{tblr} \end{document}

I am trying to create a bibliography which contains references between certain entries. E.g., in entry [2] I would like to have a text saying "conference version of [1]" (where [1] refers to another entry of the same bibliography. One way of achieving that seems to be to add something like note = {conference version of \cite{JournalVersion}} I am, however, looking for a cleaner/more structured way of achieving this. It seems to me that the field related should be the solution here -- and it does work, if I want to reference the other entry by, e.g., title. However, I have not been able to get it to work using the reference itself. My current MWE is !BIB program = biber \documentclass{article} \usepackage{biblatex} \begin{filecontents}{literature.bib} @article{JournalVersion, author = {Graf, Lukas}, title = {Title A}, journal = {Journal}, year = {2020}, } @InProceedings{ConferenceVersion, author={Graf, Lukas}, title={Title B}, booktitle={Conference Proceedings}, year={2019}, related = {JournalVersion}, relatedtype = {conferenceof} } @InProceedings{ConferenceVersionVar, author={Graf, Lukas}, title={Title C}, booktitle={Conference Proceedings}, year={2019}, note = {conference version of \cite{JournalVersion}} } \end{filecontents} \addbibresource{literature.bib} \newbibmacro*{related:conferenceof}[1]{conference version of % \entrydata*{#1}{% \usebibmacro{title} \printtext[labelnumberwidth]{\printfield{labelnumber}}% }% } \begin{document} \nocite{*} \printbibliography \end{document} Using biber and pdflatex, this produces the following output: Here, entry [3] shows how the desired output looks like (but it is achieved using the note-field), entry [2] is the one where I tried (and failed) to implement an approach using the related-field. I additional reference [1] here by title, to test whether the related-field itself works.

I’ve found that the secret behind BaKoMa’s incremental compilation seems to be hidden in itex.dll, which is located in the BaKoMa installation directory. There’s a reverse-engineering repository available at https://github.com/morluto/rea. Has anyone tried using Claude or ChatGPT to help implement incremental compilation? update Claude or ChatGPT has just blocked REA, so now I recommend that everyone use the open-source DeepSeek instead.

I am looking for a way to highlight the end of a mathematical calculation. Not to say it's important, like \boxed does, but merely to clarify what one has ended with. See the red in the following image: So it can be translated to the following (considering \asresult{} draws the red line as above): \documentclass{article} \usepackage{amsmath, tikz} \newcommand{\diff}{\mathrm{d}} % differential pebble \newcommand{\asresult}[1]{ % result highlight %... } \begin{document} The derivation of the derivate of the exponential, under such new tools, needs a re-route first: \begin{align*} e^{\diff x} &= \sum_{k=0}^\infty \frac{\diff x^k}{k!} \\ &= \asresult{1 + \diff x} \\ (\diff e^x)(t) &= \lim_{h \to 0} e^{x(t+h)} - e^{x(t)} \\ &= e^{x(t)} \lim_{h \to 0} e^{x(t+h) - x(t)} - 1 \\ &= e^{x(t)} (e^{\diff x(t)} - 1) &= \asresult{e^{x(t)} \diff x(t)} \end{align*} And with that, one deduces $\cfrac{\diff e^x}{\diff x} = e^x$, QED. \end{document} How can I add this \asresult?

How can I link a part toc into the part header page? I am trying to implement part specific and chapter specific toc on their relative title headers. The code for the chapter toc is based directly on pp 414-417 of memman.pdf and works well. I (naively) thought that repeating the code but replacing chapter with part would result in a corresponding part toc. My implementation of this does not seem to hook the part and the toc together. The attached code shows the wanted main toc, and chapter specific toc; but does not show the part toc. I expected a toc very similar to that for chapter on the title page. My example below shows the code for the chapter and the part toc. The part toc portion has been bounded by &**********. I have removed a lot of code concerning toc formatting, so the formats may be off. To aid me I have used: memoir: Chapter TOCs (Part 1) memoir: Chapter TOCs (Part 2) memoir: Chapter TOCs (Part 3) These have been very helpful, but when they venture into Tex code, rewriting parts of memoir, and @ symbols and the like, they are way above my competence. \documentclass{memoir} \usepackage{lipsum} \makeatletter \newcounter{tocmarker} \renewcommand\mempreaddchaptertotochook{\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand\mempreaddparttotochook {\cftinserthook{toc}{stop-\thetocmarker}} \renewcommand{\mempostaddchaptertotochook}{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth \newcommand\chaptertoc{ \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}} \let\changetocdepth\@gobble \normalchangetocdepth{-10} \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{2}} \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}} \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}} \par\bigskip \@afterheading } %******************************* \renewcommand\mempostaddparttotochook{% \stepcounter{tocmarker}\cftinserthook{toc}{start-\thetocmarker}} \let\normalchangetocdepth\changetocdepth % for later \newcommand\parttoc{ \begingroup \setcounter{@memmarkcntra}{\value{tocdepth}} \let\changetocdepth\@gobble \normalchangetocdepth{-10} \cftinsertcode{start-\thetocmarker}{\normalchangetocdepth{1}} \cftinsertcode{stop-\thetocmarker}{\normalchangetocdepth{-10}} \let\tocheadstart\relax \let\printtoctitle\@gobble \let\aftertoctitle\relax \tableofcontents* \endgroup \setcounter{tocdepth}{\value{@memmarkcntra}}% \par\bigskip \@afterheading } \makeatother %******************************* \begin{document} \tableofcontents* \part{Rewrite v2} \parttoc \chapter{Chapter} \chaptertoc \section{Section} \lipsum \end{document}

Good evening everyone, I am facing a problem when I designate crystallographic faces with the Miller notation (via the miller package). Typing the following code: \documentclass[varwidth=15cm, border=1pt, 11pt]{standalone} \usepackage{amsmath} %\usepackage{physics} \usepackage{fontspec} \usepackage{miller} \setmainfont{STIX Two Text} \usepackage[math-style=upright,mathbf=text,mathbf=sym,mathrm=text,mathrm=sym]{unicode-math} \setmathfont{STIX Two Math} \begin{document} \begin{equation*} \hkl(110)\equiv\hkl(11-20) \end{equation*} \end{document} Leads me to this: I am struggling in getting the bar over the "2" closer to the number. Can the distance between these two be set? Thank you in advance for your help.

The folarrow package, available for amscd, xy-pic, and tikz-cd, provides the possibility of placing a marking or description at the center of the arrow's tail. I wonder whether it is possible to obtain markings of the same size, both for the tail and the arrow, with one, two, or four bars, similarly to the three-bar marking provided by folarrow. \documentclass{article} \usepackage{tikz-cd,amssymb} \usepackage{folarrow} \begin{document} \begin{tikzcd} A \arrow[r, foliated] \arrow[rd, "\smallsetminus" marking] & B \arrow[d, "///" marking] \\ & C \end{tikzcd} \end{document}

Here is a MWE where the caption of a longtable is being tagged as a table row (TR) and as a header row (TH) using lualatex (and lualatex-dev) with tagging=on. This leads to Regularity errors in the Adobe Acrobat checker. [I'm running the latest MikTeX updates with latex-tools updated as well.] Am I doing something incorrectly, or is there a longtable conflict with the tagging tools? It's listed as compatible at latex3.github.io/tagging-project/tagging-status/. Thanks! \DocumentMetadata{ lang = en-US, tagging = on, tagging-setup = {math/setup={mathml-SE,mathml-AF}}, check-tagging-status } % END \DocumentMetadata{} \documentclass[letterpaper,12pt,oneside]{report} \usepackage{longtable} \newcommand{\tn}{\tabularnewline} % Shorthand used for cleaner table entries \begin{document} \noindent This table is being tagged incorrectly.

The following picture shows what I want. I add cbx:cnparens to replace cbx:parens. But maybe I don't replace all of cbx:parens, then which are not replaced? By the way, don't change other cite commands, such as \cite and \cites. Note that caspervector-ay bases on authoryear-comp.

Then how to solve the problem?
