The enumext package allows inline lists with a set number of columns that can be overridden, like this: \documentclass{article} \usepackage{enumext} \begin{document} \begin{enumext*}[columns=2] \item Short \item Short \item Short \item Short \item(2) A longer item that takes both columns to show \item Short \item Short \item Short \item Short \end{enumext*} \end{document} This works well if most items need the short column, and there's an occasional longer item. I have the opposite setup: most of my items are longer, but there's an occasional pair of short items. I could do this with: \documentclass{article} \usepackage{enumext} \begin{document} \begin{enumext*}[columns=2] \item(2) A longer item that takes both columns to show \item(2) A longer item that takes both columns to show \item Short \item Short \item(2) A longer item that takes both columns to show \item(2) A longer item that takes both columns to show \end{enumext*} \end{document} But writing (2) every time is annoying. Is there a way to say that (2) is the default, and then specify (1) for the short items? Something like: \documentclass{article} \usepackage{enumext} \begin{document} \begin{enumext*}[columns=2,item-columns=2] % Package enumext Error: The key 'item-columns=2' is unknown by environment 'enumext*' and is being ignored. \item A longer item that takes both columns to show \item A longer item that takes both columns to show \item(1) Short \item(1) Short \item A longer item that takes both columns to show \item A longer item that takes both columns to show \end{enumext*} \end{document} I've tried \NewCommandCopy\olditem\item \RenewDocumentCommand\item{D(2)}{\olditem(#1)} Within the {enumext*} environment this causes an error ("! Missing number, treated as zero." and then a fatal error). Outside the environment this causes the next item to display as "()2).[]", but with less spacing. (Note that this document needs to be tagged, so using the enumitem or enumerate packages is not an option.)

Learning from the classical egreg's solution for example here and here, I try to construct the custom symbols: with the following code: \documentclass{article} \usepackage{amsmath} \makeatletter \newcommand{\myge}{\mathrel{\mathpalette\myrel@{\@firstoftwo}}} \newcommand{\myle}{\mathrel{\mathpalette\myrel@{\@secondoftwo}}} \newcommand{\myrel@}[2]{% \begingroup \setbox\z@=\hbox{$\m@th#1=$}% \vcenter to \dimexpr.75\ht\z@\relax{% #2{% \hrule width \dimexpr2\wd\z@\relax \vfill \hrule width \wd\z@ }{% \hrule width \wd\z@ \vfill \hrule width \dimexpr2\wd\z@\relax }% }% \endgroup } \makeatother \begin{document} \[ a \myge b \quad a \myle b \] \[ \displaystyle a \myge b \quad \textstyle a \myge b \quad {}_{\scriptstyle a \myge b} \quad {}_{\scriptscriptstyle a \myge b} \] \[ \displaystyle a \myle b \quad \textstyle a \myle b \quad {}_{\scriptstyle a \myle b} \quad {}_{\scriptscriptstyle a \myle b} \] \end{document} but which gives: I want to know that, based on my code, any suggestions to change the rule from butt to rounded? I don't think with tikz is a good choice... here...

I've been using the OpenType LetterSpace font feature to adjust tracking. It does what I want, but has the side effect of creating a new font instance, which is annoying when babel is in use as the newly created instance is not known to babel. I'd like a drop in alternative implemented in Lua that behaves the same. But it's beyond my skill and understanding. Requirements: No change in the word spacing (like fontspec). Like for like behaviour when same number is supplied as I was using with LetterSpace (I already spent time tuning things to this number). Group safe. Switch-like behaviour (like \bfseries). Optional compatibility with the microtype package if loaded. I probably don't care specifically what happens if you try and use both tracking methods at the same time – one or the other in use is sufficient. But other microtype features need to still work (like protrusion, etc.). Here's a MWE that shows the current behaviour I have with the LetterSpace option. If possible, I'd like the numbers and output to match. %! TeX Program = lualatex \documentclass{article} \pagestyle{empty} \usepackage{fontspec} \setmainfont{Noto Serif} \newlength{\testlen} \newcommand{\settracking}[1]{% \addfontfeatures{LetterSpace=#1}} \begin{document} \begin{tabbing} \settowidth{\global\testlen}{Test Test} Test Test \= width: \the\testlen \\ \settracking{-5}\settowidth{\global\testlen}{Test Test} Test Test \> width: \the\testlen \\ \settowidth{\global\testlen}{Test Test} Test Test \> width: \the\testlen \\ \end{tabbing} \end{document}

I have been asked to introduced negated mathrel symbols in NewCM that do not exist in Unicode standard. Before I get into adding extra symbols in NewCMMath I would like to make sure that a macro does not suffice. I tested with the \not command or relative packages like centernot without good results. Then there is \ooalign. For example, \documentclass{article} \usepackage[olddefault]{fontsetup} \makeatletter \newcommand{\ndisin}{\mathrel{\mathpalette\overlay@slash\disin}} \newcommand{\overlay@slash}[2]{% \ooalign{$\m@th#1#2$\cr\hss$\m@th#1/$\hss}% } \makeatother \begin{document} $y\ndisin A_{y\ndisin A_{y\ndisin A}}$ \end{document} Produces This shows that exactly centering the two symbols is not always good. The slash should be better placed a bit to the right (centered with respect to \in). So the question is if it is possible to make such adjustments on the above or other code to get the desired result, or one has to go to the font level and design new characters.

I am using VS Code with the LaTeX Workshop extension on Windows 11. Recently, I installed HyperSnips and encountered an annoying issue: whenever I type a period (.), it automatically triggers a suggestion for \dots. This is particularly frustrating when ending a sentence and starting a new line. I've tried several workarounds, but none have worked. The issue disappears when I uninstall HyperSnips, but returns as soon as I reinstall it. I’ve searched through my latex.hsnips file but couldn't find any snippet matching this behavior. I even tried deleting the file entirely, but the issue persists. How can I disable this specific behavior? Has anyone else encountered this issue? Thank you! Here is the screenshot:

I am having problems with superscripts in tablenotes, specifically, when the superscript comes before a right parenthesis, they are correct, but before a right bracket, extra space is being inserted. I initially was just using the plain tnote, but that behaviour was even worse; I discovered a workaround with 'xspace' and this works apart from what I have just described. This lualatex, by the way. \documentclass[a4paper,14pt]{extarticle} \usepackage[a4paper,left=0.75in,top=0.25in,bottom=0.25in,landscape]{geometry} \usepackage{fontspec} \usepackage[main=greek]{babel} \babelprovide[onchar=ids]{american} \setmainfont[Ligatures=TeX]{Gentium} \usepackage{booktabs} \usepackage{array} \usepackage[flushleft]{threeparttable} \usepackage{xspace} \setlength{\tabcolsep}{10pt} \setlength{\parindent}{0pt} \begin{document} \thispagestyle{empty} \renewcommand{\arraystretch}{1.25} \newcommand{\tss}[1]{\textsuperscript{#1}\xspace} \begin{threeparttable} \begin{tabular}{l !{\kern20pt} l} \multicolumn{2}{c}{\textsc{First Declension}}\\ \multicolumn{1}{c}{\textsc{Masc.}} & \multicolumn{1}{c}{\textsc{Fem.}} \\ xxx, xxxx & xxx, xxx, x \\ xxx, [xxx\tss{9}] & xxx, xxxx \\ x, x & x, x \\ xxx, xxxx\phantom{, xxx} & xxx, (xxx\tss{10}), xxxx \\ xxx, xxx\tss{11}, x & [xxx\tss{12}], xxx, x \\ \multicolumn{2}{c}{x} \\ \multicolumn{2}{c}{xxx} \\ \multicolumn{2}{c}{xxx} \\ \multicolumn{2}{c}{xxx, [xxxx\tss{13}]} \\ \multicolumn{2}{c}{xxx, [xxx, xxxx, xxxx, xxx, xxxx]} \\ \multicolumn{2}{c}{xxxx} \\ \end{tabular} \begin{tablenotes} \small \item [9] Some proper names in Lesser Quux. \item [10] Some proper names in Plat., Xen., Thuc., etc. \item [11] Aristophanes and Plutarch. \item [12] Often in the poets and inscrr.; sometimes in Plato. \item [13] Foobar. \end{tablenotes} \end{threeparttable} \end{document}

I have been using TeX since 1986 and Type 1 fonts since the early 90s, courtesy of Berthold Horn. Moreover, I created my own fontnames and mappings for T1 fonts and, therefore, tfm files. I should also mention that I have a long-standing allergy to LaTeX and its derivatives, and so work only in plain TeX. But now I have somehow modernized my TeX installation due to a disastrous update to Fedora 44, so none of my non-CM Type 1 fonts work at all. When I attempt to use, say, AGaramond-Regular, I get mktexnam errors (yes, all my font files have Adobe PostScript names): kpathsea: Running mktextfm AGaramond-Regular /usr/share/texlive/texmf-dist/web2c/mktexnam: Could not map source abbreviation A for AGaramond-Regular. /usr/share/texlive/texmf-dist/web2c/mktexnam: Need to update /usr/share/texlive/texmf-dist/fonts/map/fontname/special.map? mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; ; nonstopmode; input AGaramond-Regular This is METAFONT, Version 2.71828182 (TeX Live 2023) (preloaded base=mf) Of course, METAFONT fails in short order. Any suggestions? My preference would be to ignore all the font-handling changes made in the last few years, but I suspect that that’s a lost cause. Thanks! Fred

I am using CircuitTikZ and often need to connect wires or labels to component anchors. However, it is not always easy to know which anchors are available for a specific component. For example, different components may provide anchors such as north, south, in, out, gate, collector, emitter, etc., and the available anchors vary depending on the component type. When building more complicated schematics, I frequently need to stop and search through the documentation to check anchor names. I was wondering whether there is a way to programmatically: List all available anchors of a given CircuitTikZ/TikZ shape/components, and/or Visualize those anchors directly on the rendered component. For example, something conceptually like: \showanchors{a component/shape} that would either print all anchor names and draw markers/labels on the component itself. So my question is: Is there a practical way to list all anchors associated with a TikZ/CircuitTikZ shape? My motivation is mainly usability and workflow efficiency. A tool like this would make it much easier to explore unfamiliar components and reduce the need to constantly check the manual, especially for beginners or occasional CircuitTikZ users. This is an example of visualizing the anchors to help wiring from CircuiTikz documentation. A possible MWE (clearly, the pin thing must be adjusted somehow to have a better distribution, and to take into account that labels can have spaces and strange characters, but well...). The task it to substitute the \allanchors definition with something automatic, see the comment above it. \documentclass[border=10pt]{standalone} \usepackage[T1]{fontenc} \usepackage[siunitx, RPvoltages]{circuitikz} \begin{document} \begin{tikzpicture}[every pin/.append style={text=red, inner sep=1pt, font=\tiny\ttfamily}] \node [npn](myshape) at (0,0) {}; % Example: this should be autofilled % Basically, for every shape named, say, "gizmo", the anchor "spot" % is a macro named pgf@anchor@gizmo@spot % --- so to do what you want, you should be able to find all % the macros with that pattern that exist % (and I do not know if this is possible in TeX in general, % maybe in LuaTeX...). \newcommand{\allanchors}{center,E,B,south} \foreach \anc in \allanchors { \node[circ, pin=45:\anc] at (myshape.\anc) {}; } \end{tikzpicture} \end{document}

First an MWE is as follows. \documentclass{article} \usepackage{amsmath} \usepackage{amsthm} \begin{document} \begin{proof} \begin{align*}{2} x&=y&\quad&\text{test test}\\ &=z&&\text{test.}\qedhere \end{align*} \end{proof} \end{document} As you see, to make the texts be aligned left, I add an empty column in the align* environment. But the width of the empty column is too big, so is there any way to specify it? By the way, I have to use align* or align to make the square be aligned to right in the final line in proofs. Summary Combining @cfr 's solution and the solution here, the problem is solved.

I have this MWE (it must be zoomed in on): I want the red line to go all the way to the green one on the top, but not exceed the dark gray on the bottom. Likewise, the green should be bounded by, and extruded to the boundary also. (The green one goes beyone on top, but we just can't see it due to the ligh gray triangle occluding it). I would like for this to be as automatic as possible. I want it to look like this: This is my use case: \documentclass[tikz,border=1cm]{standalone} \begin{document} \begin{tikzpicture} \fill[gray] (0,0) -- (1,1) -- (1,0) -- cycle; \draw[thick,green] (0.75,0.25) -- (0.25,0.25); \fill[gray!50!white] (0,0) -- (1,1) -- (0,1) -- cycle; \draw[thick,red] (0.1,0.25) -- (0.25,0.25); \end{tikzpicture} \end{document}

I am using the memoir class to write my thesis, and I found that this warning regarding \addtodef being deprecated is triggered whenever I load the natbib package. Below is a MWE: \documentclass{memoir} \usepackage{natbib} \begin{document} Hello \end{document} If I comment out \usepackage{natbib}, the warning goes away. Does anyone know the reason for that? Is this safe to ignore? I'm just worried that I'll carry on using this and then at some point in 2026 \addtodef will be removed and for some reason that will mess up my document. Just to clarify, I am using natbib over biblatex because I am already used to it and I found biblatex to be a nightmare to format it the way I would like it to be. For completion, the full warning message is: Class memoir Warning: \addtodef is marked deprecated and will be removed in 2026, use instead \patchcmd, \pretocmd or \apptocmd from the etoolbox package (which is autoloaded by the class) on input line 5.

I am trying to typeset exercise/question content inside containers of different widths. For example, the same content may be placed inside a minipage of width 21cm, or inside a narrower minipage of width 10cm. The content may include normal text, images, tables, and display equations. My goal is that the layout should adapt automatically to the available width. In particular, long display equations should be broken automatically when the width becomes smaller. Here is a simplified example: \documentclass{article} \usepackage{amsmath} \usepackage{graphicx} \usepackage{array} \usepackage{booktabs} \usepackage{mwe} \begin{document} \noindent \begin{minipage}{21cm} \textbf{Question 1.} A particle moves along a straight line. Its position at time \(t\) is given by the function \[ s(t)=3t^4-8t^3+6t^2-12t+5. \] The following diagram illustrates the motion of the particle: \[ \includegraphics[width=0.6\linewidth]{example-image} \] The table below gives some measured values: \[ \begin{array}{c|c|c|c|c} t & 0 & 1 & 2 & 3 \\ \hline s(t) & 5 & -6 & 9 & 86 \end{array} \] Find the velocity and acceleration of the particle at \(t=2\). Also simplify the following expression: \[ \frac{(x^2+2xy+y^2)(a^2-b^2)+(x-y)(a+b)^2} {\sqrt{x^4+2x^2y^2+y^4}+a^3b-ab^3+x^2a^2-y^2b^2} \] \end{minipage} \vspace{1cm} \noindent \begin{minipage}{10cm} \textbf{Question 1.} A particle moves along a straight line. Its position at time \(t\) is given by the function \[ s(t)=3t^4-8t^3+6t^2-12t+5. \] The following diagram illustrates the motion of the particle: \[ \includegraphics[width=0.6\linewidth]{example-image} \] The table below gives some measured values: \[ \begin{array}{c|c|c|c|c} t & 0 & 1 & 2 & 3 \\ \hline s(t) & 5 & -6 & 9 & 86 \end{array} \] Find the velocity and acceleration of the particle at \(t=2\). Also simplify the following expression: \[ \frac{(x^2+2xy+y^2)(a^2-b^2)+(x-y)(a+b)^2} {\sqrt{x^4+2x^2y^2+y^4}+a^3b-ab^3+x^2a^2-y^2b^2} \] \end{minipage} \end{document} In the wider minipage, the content looks acceptable. However, in the narrower minipage, the long display equation overflows the available width. What I would like is something like an “automatic responsive layout”: Text should wrap according to the current minipage width. Images should scale relative to the current width, for example using \linewidth. Tables should ideally fit or adapt to the available width. Long display equations should automatically break into multiple lines when necessary. I know that I can manually rewrite the long equation using environments such as align, aligned, multline, or split, for example: \begin{multline} \frac{(x^2+2xy+y^2)(a^2-b^2)+(x-y)(a+b)^2} {\sqrt{x^4+2x^2y^2+y^4}+a^3b-ab^3+x^2a^2-y^2b^2} \end{multline} But in my real use case, the LaTeX content is generated automatically, and the container width may vary. Therefore, I would prefer not to manually decide where every long formula should be broken. In my actual project, the LaTeX source is not written manually. It is generated from structured exercise data. The same exercise may be rendered in different layouts, such as a full-page layout, a two-column layout, or a card-like layout. Therefore, I am looking for a robust strategy rather than a one-off manual fix for a single equation. My questions are: Is there a recommended way in LaTeX to make mathematical content adapt automatically to different container widths? Can display equations be automatically line-broken depending on the current \linewidth? If full automatic line breaking is not possible, what is the usual robust approach for generating such content automatically? Are packages such as breqn, tabularx, adjustbox, or resizebox appropriate for this kind of problem? What is the best practice for this situation?

I'm using TeXLive on a Fedora installation. I updated Fedora 43 to Fedora 44 last week, and TeXLive was updated in the process. The version used now is LaTeX2e <2025-11-01> L3 programming layer <2026-01-19> but I don't remember the previous version number. Compiling even small documents feels much slower than before (about 4 to 5 times slower). I didn't change anything to my TeX configuration. I'd like to find the cause and a solution. Is there any way to measure performance (document processing, then disk reads/writes) for TeX itself to identify the bottleneck(s)? Incidentally, the engine I use is XeTeX 3.141592653-2.6-0.999998 (TeX Live 2026) with kpathsea version 6.4.2 Thanks for any hint! Thanks

I have a macro for typesetting Attribute Value Matrices (AVMs). Sometimes I want to add a little bit of vertical space. My understanding is that I type \\[2mm] and then 2mm space is inserted. But this is not what happens. Sometimes I have to add 8mm or 10 or 12. It somehow seems to depend on what happened before. But why? And how does it work and is there anything I can do to get the desired behavior? \documentclass{scrartcl} \usepackage{etex} \usepackage{array} \newcommand{\nliste}[1]{% \mbox{$\langle$\upshape\normalfont#1$\rangle$}% } \newcommand{\eliste}{% \mbox{% $\left\langle\right\rangle$}% } \newcommand{\ms}[2][]{% \ifdim\lastskip=-1pt % flag value \mbox{}\\*[-.8\baselineskip]% \else \ifnum\lastpenalty=-10000 % other flag value \mbox{}\\*[-.8\baselineskip]% \fi \fi \mbox{% \delimiterfactor=1000 \delimitershortfall=0pt\tabcolsep=0pt% $\hspace{-2pt}\left[% \begin{tabular}{>{\upshape\scshape}l@{}>{\hspace*{5pt}\normalfont\itshape}l} \if\relax\detokenize{#1}\relax\else \multicolumn{2}{>{\normalfont\itshape}l}{#1}% \\% \fi% #2% \end{tabular}% \right]\hspace{-2pt}$% }% % \par\vspace{1mm}% \vspace{1mm}% } \newcommand{\ibox}[1]{{% \setlength{\fboxsep}{1.25pt}% \fbox{$\scriptstyle #1$}% }} \newcommand{\liste}[1]{% \mbox{% $% \left\langle\mbox{\upshape\normalfont#1}\right\rangle% $% }%\\[2pt]% } \newcommand{\ind}[1]{\mbox{$_{\ibox{#1}}$}} \begin{document} \ms{ \ldots & \ms{ cat & \ms{% head & verb \\ arg-st & \ibox{1} $\oplus$ \ibox{2} $\oplus$ \nliste{ V[\textit{inf}, \textsc{lex}+, \textsc{subj}~\ibox{1}, \textsc{comps}~\ibox{2}, \textsc{ltop} \ibox{3} ] } }\\ cont & \ms{ ltop & \ibox{4}\\ ind & \ibox{5} event } }\\ rels & \liste{ \ms[scheinen]{ lbl & \ibox{4}\\ arg0 & \ibox{5}\\ arg1 & \ibox{6}\\ } }\\[10mm] hcons & \liste{ \ms[qeq]{ harg & \ibox{6}\\ larg & \ibox{3}} } } \end{document}

EDIT I am using the mathptmx package to achieve a Times New Roman aesthetic. However, it seems to me that the Greek letters ($\lambda, \mu, \omega$) seem to lose their relative weight or scale inconsistently compared to the Latin constants. Is this an inherent limitation of the virtual fonts in mathptmx, and how can I force a more robust scaling for these mathematical elements? Working example: \documentclass{article} %\usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{mathptmx} % Times New Roman style \usepackage{amsmath,amssymb,amsthm} %------------------------------------------------------------- % Custom macros %------------------------------------------------------------- \newcommand{\cL}{c_{\mathrm{L}}} % longitudinal wave speed \newcommand{\cT}{c_{\mathrm{T}}} % shear wave speed \begin{document} (...) The material is assumed to be homogeneous, isotropic, linearly elastic, and lossless (non-dissipative), characterised by the real-valued Lam\'e constants $\lambda$ and $\mu$ (with $\mu > 0$ and $3\lambda + 2\mu > 0$) and mass density $\rho > 0$. The corresponding longitudinal and shear wave speeds are % \begin{equation} \cL = \sqrt{\frac{\lambda + 2\mu}{\rho}}, \qquad \cT = \sqrt{\frac{\mu}{\rho}}, \label{eq:wavespeeds} \end{equation} % with $\cL > \cT > 0$. The material obeys the generalised Hooke's law % \begin{equation} \sigma_{ij} = \lambda\,\delta_{ij}\,\varepsilon_{kk} + 2\mu\,\varepsilon_{ij}, \qquad \varepsilon_{ij} = \tfrac{1}{2}(U_{i,j} + U_{j,i}), \label{eq:hooke} \end{equation} % where $\delta_{ij}$ is the Kronecker delta and the usual summation convention over repeated indices is employed. Substituting \eqref{eq:hooke} into the equations of motion $\sigma_{ij,j} + \rho\,\partial_{tt} U_i = 0$ and using the time-harmonic ansatz, so that $\partial_{tt} \to -\omega^2$ and hence $\ddot{U}_i = -\omega^2 U_i$, yields the time-harmonic Navier equations: % \begin{equation} \mu\,\nabla^2 \mathbf{U} + (\lambda+\mu)\,\nabla(\nabla\cdot\mathbf{U}) + \rho\omega^2\,\mathbf{U} = \mathbf{0} \quad \text{in } \Omega, \label{eq:navier} \end{equation} % where $\nabla^2 = \partial^2/\partial x^2 + \partial^2/\partial y^2$ is the two-dimensional Laplacian. Equation~\eqref{eq:navier} is a system of two coupled second-order partial differential equations for $U_x$ and $U_y$. \end{document} When using the more recent \usepackage{newtx} I get error messages.

when I open the pdf of my MWE in Adobe Acrobat and try to sign the signature field, I get the error 2013 which warns me that my fonts are not embedded. To be more precise, it's the Helvetica font that's not embedded. I thought that compiling with LuaLaTeX would make all my fonts embedded, but that's not the case. I assume that Helvetica is used by the \textfieldnew command, despite f.textFont = 'ArialMT'. \documentclass[ a4paper, fontsize=10pt headsepline=0.4pt ]{scrartcl} \usepackage[english, main=ngerman, shorthands=off]{babel} \usepackage{fontspec} \setmainfont{Arial} \setsansfont{Arial} \usepackage{eforms} \begin{document} \newcommand{\textfield}[5]{ \edef\Titel{#2} \TextField[name=#1, width=#3, charsize=10pt, height=1em, format = { var f = this.getField('#1'); f.textFont = 'ArialMT';}, #4]{}#5 } \newcommand{\textfieldnew}[5]{% \edef\Titel{#2}% \TextField[name=#1, width=#3, charsize=10pt, height=1em, format = { var f = this.getField('#1'); f.textFont = 'ArialMT';}, #4]{}% #5% } \textfieldnew{Test}{}{7.5cm}{default={Test}, onblur={this.getField('TestEN').value = event.value;}}{} \sigField{Signatur1}{7.5cm}{1.2cm} \end{document} Is there any way to embed the fonts in LaTeX or change the font of the textfields?

Beginning with the first page after the table of contents, I want to change the pagestlye (from standard plain.scrheadings) to scrheadings, like so: \pagestyle{plain.scrheadings} \tableofcontents \clearpage \pagestyle{scrheadings} I now want to transfer these lines' effect to the preamble (located in a *.cls if this makes a difference). I would have come up with \pagestyle{plain.scrheadings} \AfterStartingTOC[toc]{ \clearpage \pagestyle{scrheadings} } that doesn't do anything (I guess it is run locally?) which is why instead I tried \pagestyle{plain.scrheadings} \AfterStartingTOC[toc]{ \clearpage \pagestyle{scrheadings} \global\let\currentpagestyle\currentpagestyle } that also doesn't do anything (although now defined globally?). I then included \pagestyle{plain.scrheadings} \AfterStartingTOC[toc]{ \clearpage \pagestyle{scrheadings} \makeatletter \global\let\@evenhead\@evenhead \global\let\@oddhead\@oddhead \global\let\@evenfoot\@evenfoot \global\let\@oddfoot\@oddfoot \makeatother } which eventually seems to have the same effect as the first lines. Is this the way to go or are there better implementations? Like this for example? \let\OldTableOfContents\tableofcontents \renewcommand{\tableofcontents}{% \OldTableOfContents \clearpage \pagestyle{scrheadings} } The MWE: \documentclass{scrreprt} \usepackage[plainheadsepline,headsepline,singlespacing]{scrlayer-scrpage} \clearpairofpagestyles \lohead*{Name} \rohead*{Thesis Type} \rofoot{\pagemark} \pagestyle{plain.scrheadings} \begin{document} \chapter*{Chapter before the ToC} \tableofcontents %These lines' effect should be transferred to the preamble: \clearpage \pagestyle{scrheadings} % \chapter{Chapter after the ToC} There is text here ...\newpage ... and here ... \end{document}

Extension of my question for half plane. I want to be able to draw figures like the following one (i.e. figures for the classic Boussinesq/Lamb problems). After some trial and error, inspired by the following answer in a recent question of mine I got something not bad. \documentclass{standalone} \usepackage{tikz} \usepackage{amsmath} \usetikzlibrary{decorations.pathmorphing, shadings, arrows.meta, calc} \tikzset{ potato/.style={ rounded corners=2pt, decorate, decoration={random steps, segment length=5mm, amplitude=3pt}, } } \begin{document} \begin{tikzpicture} \pgfmathsetseed{2345} \begin{scope} \clip (-4, -6) rectangle (4, 0); \draw[potato, top color=gray!15, bottom color=gray!50] (0,0) ellipse[x radius=3.2cm, y radius=3.2cm]; \end{scope} \fill[gray!10] (0,0) ellipse[x radius=3.2cm, y radius=0.9cm]; \draw[thick] (0,0) ellipse[x radius=3.2cm, y radius=0.9cm]; \draw[-{latex}, thick] (0,0) -- (0, -2.4) node[below] {$z$}; \draw[-{latex}, thick] (0,0) -- (3.8, 0) node[right] {$x$}; \draw[-{latex}, thick] (0,0) -- (-2.55, -0.93) node[below left] {$y$}; \filldraw[black] (0,0) circle (2pt) node[below left] {$O$}; \draw[-{Stealth}, very thick] (0, 2.0) -- (0, 0.05) node[right, yshift=1.5cm] {$P$}; \end{tikzpicture} \end{document} There are a couple of issues as shown in the figure. First why the white space below the figure and second it appears to me that the 'wiggy' curve does not fit correctly to the ellipse. Thanks for any improvements.

Is there a version of the original display Computer Modern font cminch extended with German umlauts – letters with diaeresis – ÄÖÜ? I have found csinch and plinch fonts with Czech and Polish letters but still missing umlauts. Or which alternatives do you suggest for notice plate?

So I'm compiling with lualatex, using fontspec with unicode-math. It seems that both NewComputerModernMath and LatinModernMath produce a kerning issue with the letter "T". Just build $(T)$ or $\bigl( T \bigr)$ - or see the screenshot below. With the help from AI, I currently have a totally MYSTERIOUS result: for math inside \[ \], the patch only works for sized parentheses (e.g. T \bigr)), but not the plain ones; for math inside \begin{aligned*} \end{aligned*}, the patch only works for plain parentheses, but not the sized ones.

I am using a MiKTex Windows distribution of LaTeX and trying to create a custom package. I am unclear how Latex parses arguments and expl3 makes absolutely no sense to me! For now, what I would like to accomplish is a routine the passes arguments to a .sty file and for the file to do basic error checking and print the values passed to it for confirmation. Thanks for any assistance! I am trying to learn and improve.

How can one create a figure like the following? Here is my attempt. I use the plot function with a combination of a parabola (for the general shape) and a sine wave (to create the "wiggles"). \documentclass[tikz,border=10pt]{standalone} \usepackage{amsmath} \begin{document} \begin{tikzpicture}[>=latex] % Draw the wavy boundary % We use a parabola-like base: 0.2*x^2 - 2 % We add a small sine component for the "roughness" \draw[thick] plot [domain=-3.2:3.2, samples=100, smooth] (\x, {0.2*\x*\x - 2 + 0.08*sin(600*\x)}); % Draw Horizontal Axis (x, u) \draw[->] (-3.5,0) -- (3.5,0) node[below right] {$x, u$}; % Draw Vertical Axis (y, v) \draw[->] (0,-2.5) -- (0,0.8) node[right] {$y, v$}; % Origin label \node[below left] at (0,0) {$0$}; \end{tikzpicture} \end{document} My problem is that the boundary appears too 'wavy'. Also there is a small unecessary part above the x-axis. Any ideas to improve the figure?

I have some lua code that generates coordinates of many triangles/quadrilaterals I then want to draw/fill. See this answer about Penrose tilings for a concrete example. The drawing is actually done in TikZ via the luadraw package, but I am wondering if I can make the code faster by replacing TikZ with l3draw. Rewriting my actual code to remove TikZ and luadraw dependences (and use l3draw or any other drawing tool) is not a complex task, but will ask me some time due to my limited programming skills. So I would prefer to know in advance if this is a good idea or not. Apart possibly performance, is there any other reasons to use l3draw over pgf for this kind of task? Edit: I am not using TikZ/pgf for the rest of the document. Suggesting to use another environment (as picture) is a valid answer.
