N.B.: I don't know if there is a technical term for what I'm trying to describe, so I just made up "two-layer" as a proxy. I have a set of course notes that have become popular among a group of colleagues. There is a desire to have an "instructor's version" with various instructional tips and hints for solutions. OK, fine, I have all that already in various files. As I've begun writing the instructor's version, it's become clear that having two separate source files (one for student, one for instructor) is supremely annoying. Any edits I want to make to the student content must then also be copied over to the instructor file. My desire is to have one source file, but two ways to compile. One would compile the whole works, creating the instructor's version. A second would skip all the instructor addenda, leading to the the student's version. This way, edits to the body and exposition need be made only once, not twice. I have to believe this is possible. I thought about creating an instructor's environment like a newtheorem to segregate out the instructor's content, but then I don't know how to toggle on or off the inclusion of those lines (and this is probably not the smart solution, anyway). Is there a way to create two versions of a document from a single file?

A strange space appears in the code below after the first \end{thmN}. The next line is slightly indented. I have a solution, see the code, by adding a "%" after \end{thmN}, but I would like my user not to have to care about that. Many thanks for you lights!

The following code snippet draws a box in box for a heading. I would like some help to improve the code so that only the top right corner of the bottom box is rounded. Most of the values are currently hardcoded, as this forms part of a larger code that calls the macro \tikzspecial defines keys that are passed as options. The height of the blue top box should be 3cm, I seem to be about a couple of mm out, any help with that I would also appreciate. \documentclass[10pt,twoside]{book} \usepackage[bottom=2cm,top=2cm, left=3cm, right=4cm,showframe]{geometry} \usepackage{tikz} \usepackage{kantlipsum} \ExplSyntaxOn \makeatletter \NewDocumentCommand{\tikzspecial}{s O +m}{ %% First band \begin{tikzpicture}[remember~picture,overlay,inner~sep=0pt,outer~sep=0pt] \draw[draw=none,fill=cyan,outer~sep=0pt,inner~sep=0pt, xshift={-2cm},yshift=-\dimexpr3cm+10pt] (current~page.north~west) rectangle (\paperwidth,2.5cm); \end{tikzpicture} %% Second band with rounded corners \begin{tikzpicture}[remember~picture,overlay] \node~at~(current~page.north~west)~[yshift=-\dimexpr3cm+5.4pt,xshift=-10pt,%.3 klls corners on left anchor=south~west,inner~sep=10pt, outer~sep=0,white,fill=black, draw=none,rounded~corners=10pt,align=left, text~width=\textwidth]{\leftskip10pt \large \sffamily\LARGE\bfseries \IfBooleanTF{#1}{}{\thechapter.\space} #3\par }; \end{tikzpicture} \vspace*{4\baselineskip} \par \@afterindentfalse \@afterheading } \makeatother \ExplSyntaxOff \begin{document} \parindent=2em % simulate chapter \stepcounter{chapter} \tikzspecial*{Some Special Layout\\ Format} \kant[1-9] \end{document}

This is a follow up to this question, which asks for delimiters with thicker lines. I would like to add the option to choose the color of these delimiters, as in the following example \documentclass[]{amsart} \usepackage{color} \begin{document} \newcommand{\Red}[1]{\textcolor{red}{#1}} \newcommand{\mynorm}[1]{\Red{\lvert} #1 \Red{\rvert}} $\mynorm{v}$ \end{document} which produces this: Thus my question is how to add this color parameter to egreg's answer to the linked question. I tried to do it myself, with no success so far.

I have been experimenting with an essentially empty tex file to see how long it takes pdflatex just to get started. On one of the fastest 2026 machines around, an Apple M4, here is what I get: Baseline (just \documentclass): 1.4s biblatex: +1.9s (the single biggest offender) microtype: +0.6s tikz: +0.6s hyperref: +0.5s All heavy packages combined: 4.8s total (3.4s of package overhead) I am now wondering whether I should regress to the older Bibtex (or Natbib??) and dump biblatex. More generally, I understand that there are formats that can replace the entire article class. Alas, what I really would like is a format that can replace just a set of style files --- or better yet, a way to "cache" a whole set of my standard style files that I am always including. Is this possible? Any ideas how to keep my beloved pidflatex output and have it move faster? pointers appreciated. /iaw

A style guide demands: heading numbers end in a period; headings titles do not hang off the number. Example of desired output: In the past I could accomplish this by modifying \@seccntformat and \@hangfrom: \documentclass{article} \makeatletter \def\@seccntformat#1{\csname the#1\endcsname.\enskip} \def\@hangfrom#1{\noindent#1} \makeatother \begin{document} \section{My section title with an extremely long title spanning multiple lines} \subsection{My subsection title with an extremely long title spanning multiple lines} \end{document} But in TeX Live 2026 with \DocumentMetadata{tagging=on}, the hanging indent reappears! I believe the tagging code enables the socket sec/title/hang whose default plug does not call \@hangfrom. I could mimic the kernel plug with my own variant and assign it to the socket: % Put the following inside the `\makeatletter`/`\makeatother` block. \ExplSyntaxOn \cs_new_protected:Npn \__tag_set_title_NOHANG:nNnn #1 #2 #3 #4 %#1 level, %#2 boolean: nonumber? (will be later \l__head_nonumber_bool) %#3 formated number /hang space %#4 title { \protected@edef\l__tag_sec_tmpa_tl {#4} \tagstructbegin{tag=\UseStructureName{sec/#1/title},title-o={\l__tag_sec_tmpa_tl}} \cs_if_exist_use:N \__tag_gincr_para_begin_int: \bool_if:NF #2 { \tagstructbegin{tag=\UseStructureName{sec/#1/number}} } \setbox\@tempboxa\hbox{{#3}} \bool_set_false:N \l__tag_para_bool %\hangindent \wd\@tempboxa\noindent %%% <-- REMOVED \noindent %%% <-- INSERTED \bool_set_true:N \l__tag_para_bool \bool_if:NTF #2 { \box\@tempboxa } { \tagmcbegin{} \tag_mc_reset_box:N\@tempboxa \box\@tempboxa \tagmcend \tagstructend } \tagmcbegin{} } \NewTaggingSocketPlug{sec/title/hang}{myoverlay} { \__tag_set_title_NOHANG:nNnn #1 } \AssignTaggingSocketPlug{sec/title/hang}{myoverlay} \ExplSyntaxOff This feels fragile. Is there a better approach? Now the plot thickens. I am actually trying to use TeX Live 2026 lualatex-dev to benefit from a bug fix. But in lualatex-dev with \DocumentMetadata (with or without tagging=on), it seems \@seccntformat is no longer called, thus there is no longer a period after the section number. I believe lualatex-dev is bringing templates into play (in the file latex-lab-testphase-sec-template.sty). I am new to templates. How do I adjust the templates to put a period after the number? And do templates then perhaps also provide a less fragile way to eliminate \hangindent so I no longer need to replace \__tag_set_title_hang (earlier part of this post)?

I'm looking for a way to combine multiple .tex files that require different .sty packages, and need to be merged into a single output document within Overleaf and without manual PDF handling. For instance, I am working on a LaTeX project (on Overleaf) where I have multiple .tex files located in a section/ directory. Each file compiles correctly on its own and uses a specific .sty package. Each package works independently and cannot be merged into one common .sty. section/Flashcard.tex \documentclass[../test.tex]{subfiles} \usepackage{Flashcard} % specific to flashcards \begin{document} % Flashcard content \end{document} section/main.tex \documentclass[../test.tex]{subfiles} \usepackage{agrphy} % specific to my course \begin{document} % Course content \end{document} Each file compiles without any issue when compiled individually. I want to point out that the two .sty files are extremely different and fundamentally incompatible by design: for example, Flashcard.sty restructures each page into 8 minipages to generate flashcards, while agrphy.sty defines a very specific layout with custom margins and a grid-based background for lecture notes. As a result, merging their behaviors into a single preamble does not seem feasible. Goal I would like to combine both outputs into a single document to distribute to my students. test.tex \documentclass[11pt,a4paper,svgnames]{book} \usepackage{subfiles} \begin{document} \subfile{section/main} \subfile{section/Flashcard} \end{document} ze problem When compiling the main document, it fails. It seems that the individual .sty packages (Flashcard and agrphy) are not properly loaded or conflict with the main preamble. From my understanding, subfiles force all subdocuments to share the same main preamble, which prevents using different packages independently in each subfile. What I have tried (desperately) subfiles: works for individual compilation, but not for combining different styles standalone: I could not get it to work properly in this setup pdfpages: this would work easily, but on Overleaf, I cannot automatically reuse the generated PDFs from other .tex files without manually downloading and re-uploading them, and I have a looooooooot to compile

I'm currently trying to graphically represent Feynman's technique. Specifically, I have the function rad(atan(sqrt(2-x*x)))/(1+x*x) which is being parametrized as rad(atan(t*sqrt(2-x*x)))/(1+x*x). I managed to create the graph for the function, \documentclass{standalone} \usepackage{tikz,pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture} \begin{axis}[ axis lines = center, axis on top, view={50}{30}, xlabel={$x$}, ylabel={$t$}, zlabel={}, xmin=-2, xmax=2, ymin=-2, ymax=2, zmin=-2, zmax=2, tick label style={font=\tiny} ] \addplot3[ surf, shader=faceted interp, faceted color=black!60, opacity=0.85, samples=22, samples y=18, domain=-1.4:1.4, domain y=-2:2, ] {rad(atan(y*sqrt(2-x*x)))/(1+x*x)}; \end{axis} \end{tikzpicture} \end{document} But I'm having trouble figuring out how to a) highlight the specific line along the function that represents rad(atan(sqrt(2-x*x)))/(1+x*x) and b) getting the axis lines to be above and below the 3d surface when the surface is above and below.

I don't understand what the difference is between \def\R{{\mathbb{R}}} and \def\R{\mathbb{R}} When compiling \R (in math mode, obviously), I get ℝ in both cases and it doesn't show an error.

I would like to plot the following function in LaTeX using TikZ or pgfplots: \[ y = x^{2/3} + 0.8 \cdot \cos(kx) \cdot \sqrt{3 - x^2} \] The domain is \( - \sqrt{3} \leq x \leq \sqrt{3} \). I need to create a nice graph where: The curve looks smooth I can easily change the value of \( k \) (number of oscillations) The modulated amplitude (the \( \sqrt{3-x^2} \) part) is clearly visible I have tried basic \addplot but I have problems with the fractional power \( x^{2/3} \) and with making the cosine oscillation look good. MWE (Minimal Working Example): \documentclass{article} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture} \begin{axis} \addplot {x^(2/3)}; % this part works, but adding the rest is difficult \end{axis} \end{tikzpicture} \end{document} pgfplots tikz-pgf plot functions graphics

My wonderful TeX friends. I need to downsize my TeXLive installation. I would like to see a list of packages that are part of a collection and remove those packages which I don't need. What I have tried doing: tlmgr list --only-installed > installed_texlive_packages.txt I tried to uninstall a package only to get an error: tlmgr remove xstacks tlmgr: saving backups to /usr/local/texlive/2025/tlpkg/backups tlmgr: not removing xstacks, needed by collection-latexextra tlmgr: no packages removed. tlmgr: action remove returned an error; continuing. tlmgr: An error has occurred. See above messages. Exiting. But there are certain packages in collection-latexextra that I use. I want to remove only those packages which I don't use or don't need. Thanks.

Does it auto-switch to OT1 internally, or is there another encoding specifically for these "missing" letters? I'm specifically talking about these specific letters: and not to the entire Greek alphabet. The reason why I'm asking about them is that these letters are included in OT1, but I don't see them anywhere in the definition of T1.

I’m writing a book using the tufte class and compiling with LuaLaTeX. I recently updated to MacTeX 2026 and noticed that the class no longer works properly, especially with cross-references. So I decided to reinstall MacTeX 2025 to make sure it worked correctly in that version. Something changed in the update and is causing an error with these references. Using MacTeX2026, the first example I’m showing you is \documentclass[]{tufte-book} \usepackage{graphicx} \begin{document} \chapter{Capítulo 1} La figura \ref{figexample} es \begin{figure} \includegraphics[width=\linewidth]{example-image-a}\label{figexample}\caption{text} \end{figure} La figura en margen es \ref{figexamplem} \begin{marginfigure} \includegraphics[width=\linewidth]{example-image-b}\label{figexamplem}\caption{text} \end{marginfigure} \end{document} which produces this result As you can see, Figure 1 is referenced correctly, but the figure in the margin is not. Now see what happens if I load the mathtools and/or amsmath packages \documentclass[]{tufte-book} \usepackage{graphicx} \usepackage{mathtools} \usepackage{amsmath} \begin{document} \chapter{Capítulo 1} La figura \ref{figexample} es \begin{figure} \includegraphics[width=\linewidth]{example-image-a}\label{figexample}\caption{text} \end{figure} La figura en margen es \ref{figexamplem} \begin{marginfigure} \includegraphics[width=\linewidth]{example-image-b}\label{figexamplem}\caption{text} \end{marginfigure} \end{document} which produces this result Thus, neither of the two figures is properly cited. While doing some research, I found that there is a new version of the tufte class called xtufte, so I decided to test it, and the result is the same—there are no correct cross-references. \documentclass[]{xtufte-book} \begin{document} \chapter{Capítulo 1} La figura \ref{figexample} es \begin{figure} \includegraphics[width=\linewidth]{example-image-a}\label{figexample}\caption{text} \end{figure} La figura en margen es \ref{figexamplem} \begin{marginfigure} \includegraphics[width=\linewidth]{example-image-b}\label{figexamplem}\caption{text} \end{marginfigure} \end{document}

I am talking about the command \ipabar, in the tipa package. I need to ask a question. How does \ipabar in tipa work internally? does it draw the bar with an equivalent of graphicx or tikz?

I am trying to tex a diagram. I use overleaf with the tikz-cd package. I am currently wrinting by Bachelor thesis and am using a LeTeX template of my university (TUM). Without this template everything worrks just fine but using this template the diagram does not compile. The problem seems to be that LaTeX interpretes the lable of the arrows as the color parameter. It seems to be a conflict with the pgfkeys and the xcolors package. The error message is the following Package pgfkeys Error: I do not know the key '/tikz/"f"'' and I am going to ignore it. Perhaps you misspelled it. Package xcolor Error: Undefined color `"g\circ f"'. Package pgfkeys Error: I do not know the key '/tikz/"g"'' and I am going to ignore it. Perhaps you misspelled it.

I want to create a perfect monochrome Periodic table (for black and white printing, etc.). 1/2. Instead of the colored "radioactive symbol" (which seems to be set hard-coded by the package), I'd like to use an asterisk '*' or a simple text character. 2/2. Secondly, the term 'Ra' in the legend must also be replaced by the star (or the other symbol used). Note: The aforementioned "radioactive symbol" seems to be (hard-coded) retrieved from the file /texmf-dist/tex/latex/pgf-periodictable/pgfPT_radio_symbol.pdf → which is located near the package file. One could therefore "hack" the problem by placing a PDF file with the same name in one's working directory. However, I'm wondering if there's a more elegant solution. PS: Since I'm not yet very familiar with the package, general suggestions for improvement are welcome.

Example: ⭅⭆⟰⟱ The size of the 4-line arrow should be the same as the font size in mathematical format. Can only be used as a LaTeX mathematical format command Summary of requirements: The size must not differ from the original LateX symbols; it must maintain the native style.

I don't quite understand why the first node is no longer pointing toward $C_0$. How can I move $C_0$ to be on the far right side, still level with the first node (kind of looking like a trapezoid) while still connected to the first node? \documentclass{article} \usepackage{tikz} \usetikzlibrary{graphs} \begin{document} \begin{center} \scalebox{1.2}{ \tikz \graph [grow right sep]{ x1 [as =$\displaystyle \int_a^b{f(x)dx}$] -> {x2[as=$C_0$, red], x3[as=$F(t)$] -> x4[as=$F^\prime(t)$] -> x5[as=$\displaystyle \int{F^\prime(t)dt}$] -> x6[as=$C(t) + C_{1}$, red]->x2}; }; } \end{center} \end{document} This is what it currently looks like: This is the intended result (essentially, ignore the terrible drawing lol): Any help or a push toward some sort of useful resource is much appreciated.

How do I write \hom_{k\text{-alg}} correctly? Semantically, this is incorrect since -alg is not text, so it shouldn't be in the normal text font but in math font. Using \mathrm however is also wrong as the - sign will become a minus sign, which has wrong spacing. What is the best way to write this? If possible, I want to avoid stuff like \mathchardef\hyph="2D and use \hyph instead of - (this is meant for a beginners course). Edit: As there is a lot of debate and confusion, here an MWE (with the "correct" command in one of my commands). \documentclass{article} \usepackage{newtxtext} \usepackage{amsmath} \newcommand{\alg}[1]{\mathord{#1\!\operatorname{-alg}}} \begin{document} \[ \hom_{k\text{-alg}}, \hom_{k\mathrm{-alg}}, \hom_{\alg{k}} \] \end{document}

I would like to typeset an equation with two alignment points, but also have an equation number on each line. What I am aiming for should look like this: \documentclass{article} \usepackage{amsmath} \begin{document} \begin{align} a &= \text{Something very very long} \\ &\begin{aligned} {}\leq b\Bigl(&ccc \\ &+d \\ &+e \Bigr) \end{aligned} \end{align} \end{document} However, the inner aligned environment produces only a single equation number, whereas I would like one number per line. I tried to solve this is using alignat. \documentclass{article} \usepackage{amsmath} \usepackage{mathtools} \begin{document} \begin{alignat}{3} a &= \mathrlap{\text{Something very very long}} \\ &\leq b\Bigl(&&ccc \\ &&& +d \\ &&& +e\Bigr) \end{alignat} \end{document} This gives me multiple equation numbers, but using \mathrlap causes the whole expression to become visually misaligned (no longer centered properly). My two tries are shown below. Is there a way to achieve what I am looking for?
