This is a package-recommendation question: What good, modern packages exist for maintaining a document with multiple versions? This is something I find myself needing constantly, for many purposes (e.g. versions in different page geometries for printing/screenreading; versions with different styles for preprint/journal versions of an article…) One option is to define conditionals like “\newif\ifsmallscreen” at the start, and manage the conditional logic by hand. A cleaner approach is provided by the rather similar packages optional and tagging: you load them at the start of the preamble with your named options/tags e.g. \usepackage[smallscreen]{optional}, and they allow conditing on thses with an interface like \opt{smallscreen}{\geometry{a5paper}}. However, both these packages have some pretty basic limitations (e.g. optional only lets you conditionally include code based on options, not exclude it; and tagging’s conditionals don’t work inside command definitions), and are also unmaintained. So for more complex versioning I end up rolling my own solution — but I miss the very clean interface provided by these packages. Are there any modern, slightly wider-featured alternatives to these packages — offering a quick (ideally one-liner) interface for specifying tags/version options at the start of a document, and then offering a robust and flexible interface for conditionals depending on these? I’ve looked through CTAN’s conditional-compilation category, but haven’t found anything suitable — multiaudience and renditions have similar aims, but offer no improvement on optional and tagging, as far as I can see.

I'm using Mac TeX 2026 with all updates on macOS 26.4 with all updates. In my book project, I discovered links to exercises and solutions do not always land in the same place. In my MWE, links to exercises from List of Exercises and links to solutions from List of Solutions land such that the entire exercise or solution box is visible. However, from each individual exercise the link to its solution lands below the box's title. This behavior is present in the links in the Debug Section pages (which do not appear in the TOC because they are only for temporary debugging). My question is: how can I get link from exercises to their corresponding solutions, and links to solutions from the Debug Section pages, to land with the entire solution box visible? I have searched the site and could not find any directly applicable question. I found one answer involving modifying something about the "height" of a link but that did not work, and I cannot find that particular post at the moment.

I am parsing input in expl3 token by token. I want to wrap characters like a or + as [a], [+], while preserving commands such as \textbf{...} and \textit{...}. The problem is that my current approach separates the command from its argument, so something like \textbf{text} is no longer preserved as a single structure.

I am trying to extract the intersection points of a closed curve using the spath3 package. Currently, I have managed to find these points by splitting the path at self-intersections and then using the spath cs (coordinate system) on the resulting components. However, I noticed that the spath3 documentation doesn't seem to provide a direct command for "finding intersections" and returning them as coordinates. My current workaround involves a somewhat manual process: splitting the path, identifying components, and then grabbing the coordinates at the end of specific segments. Here is my MWE. \documentclass[tikz, border=10pt]{standalone} \usetikzlibrary{spath3, knots, hobby, intersections} \begin{document} \begin{tikzpicture}[ use Hobby shortcut, ] \path[spath/save=trefoil] ([closed]90:2) foreach \k in {1,...,3} {.. (-30+\k*240:.5) .. (90+\k*240:2) } (90:2); \tikzset{ spath/.cd, split at self intersections=trefoil, remove empty components=trefoil, get components of={trefoil}\pathcomponents, } % Label each component at its midpoint for reference \foreach[count=\k] \cpt in \pathcomponents { \node[] at (spath cs:{\cpt} 0.5) {\tiny \k}; } % Extracting coordinates before inserting gaps \foreach[count=\k] \i in {1, 3, 5} { \coordinate (A\k) at (spath cs:\getComponentOf{\pathcomponents}{\i} 1); } \tikzset{ % Gaps are inserted after coordinate retrieval. % If inserted earlier, spath cs would only capture positions within the fragmented arcs. spath/insert gaps after components={trefoil}{10pt}{1,3,5}, } \draw[spath/use=trefoil]; % Mark the original intersection points \foreach \k in {1,2,3} { \fill[red, opacity=0.5] (A\k) circle[radius=2pt] node[above, black, opacity=1] {\color{red}\(\k\)}; } \end{tikzpicture} \end{document} While this code works, it feels like a "workaround." Is there a more concise or idiomatic way to retrieve these intersection coordinates directly using spath3 or its integration with the intersections library?

The following code: \documentclass{article} \begin{document} \[ f(x',\overline{x'}) \] \end{document} produces the following output for me: I'm a bit bothered that the heights of the primes are mismatched. My first thought for how to fix this issue was to add a phantom overline over the first argument so that the prime in the first argument would get pushed down to the same height. However, despite some experimentation with syntax (\phantom{\overline}{x'} for instance), I couldn't find something which compiles. Apologies if this has been asked before. The inverted version of this question overline over no text does not seem relevant here.

Recently I have discovered the interesting package named luacas (compilable with LuaLaTeX). To pag. 14 of the manual https://ctan.mirror.garr.it/mirrors/ctan/macros/luatex/latex/luacas/doc/luacas.pdf I have not understood the necessary packages to put in the preamble to compile the MWE to plot f and f'. Someone please, can help me? Here the fragment of the code: \directlua{ tex.print(h:tolatex()) } For Bob’s purposes, \fetch{h} is exactly what he needs: \begin{tikzpicture}[scale=0.9] \begin{axis}[legend pos = north west] \addplot [domain=-3.5:1.5,samples=100] {\fetch{h}}; \addlegendentry{$f$}; \addplot[densely dashed] [domain=-3.25:1.25,samples=100] {\fetch{dh}}; \addlegendentry{$df/dx$}; \addplot[gray,dashed,thick] [domain=-3.5:1.5] {0}; \end{axis} \end{tikzpicture} Alternatively, Bob could use \store. The \store command will fetch the contents of its mandatory argument and store it in a macro of the same name. \store{h} \store{dh}

I want to animate a DFS in an example graph. I know I can use keys like onslide to activate specific styling on a given slide, but this requires to give the instruction at the place where the node is defined. I would like to be able to just specify the order in which DFS visits the nodes, eg. \foreach \val[count=\slide from 2] in {0,1,2,3,4,5,11,16,15,14,20,19,25,18,24,,31,30,,36,42,43,38,39,46,47,40,35,34,27} {set node l\val to be red-filled starting on slide \slide} I got the idea to use a expl3 proplist to store, on a given slide, which nodes should have which style (full code below). Then I can define a custom tikz style with some code to retrieve from the proplist and do a \pgfkeysalso. Presently, this works if I set the style to eg. fill. However, setting it to eg. fill=red gives an error Package pgfkeys Error: I do not know the key '/tikz/fill=red' and I am going to ignore it. Perhaps you misspelled it. I presume this is a catcode issue, but I am not able to solve it (I tried converting from tokenlist to expl3 string, to no avail). I know I can avoid the need for an = sign by defining a custom style with the appropriate colour (and this is better code style anyway). But still, this limitation is annoying.

Code IMPORTANT: I'm not near a TeX distribution at the moment so I don't know if the following will compile but I think this is the code that I tested at home. % lualatex test.tex \DocumentMetadata{ lang = da, tagging = on } \documentclass[ danish ]{ltx-talk} \usepackage{pstricks} \begin{document} \begin{frame}{\visible<1->{Exercise}} \begin{center} \begin{pspicture}(1,1) \visible<2->{\psframe(0,0)(1,1)} \end{pspicture} \end{center} \end{frame} \end{document} Problem The problem described in the first part is now solved after updating ltx-talk but there is still a problem; if I put \visible<n->{...} (for n > 1) inside a pspicture environment, the behaviour with the picture being drawn right from the start of the frame persists.

I am using code that makes it so the mini frames are on the same line as the section names. However, when I remove navigation symbols and use \beamergotobutton{}, the mini frames can "jump" (i.e., have vertical shift). The problem does not occur if I use "smoothbars" instead. I have the following example file, modified from Beamer miniframes: side-by-side section names and navigation dots. % Source - https://tex.stackexchange.com/a/88403 % Posted by diabonas, modified by community.

The problem can be seen on the second image of the sequence. On the second image, the first mini frame dot is shifted upwards for some reason.

As a sort of follow-up to a previous question, why is "every [shape] node" applied after node options? For example, \documentclass[tikz]{standalone} \begin{document} \begin{tikzpicture}[every rectangle node/.style={draw=black, minimum width=1cm,minimum height=1cm}] \node [rectangle] {hello!}; \node [rectangle] at (2.5,0) {hello again!}; \node [rectangle,minimum height=2cm] at (0,-2) {Hello, world!}; \bgroup \tikzset{every rectangle node/.style={draw=black,minimum width=1cm, minimum height=2cm}} \node [rectangle] at (2.5,-2) {Hello, world!}; \egroup \node [rectangle] at (0,-3.75) {goodbye!}; \end{tikzpicture} \end{document} which produces The two "Hello, world!" boxes should look the same, but because of the order in which things are applied, they do not. Creating a group with "every rectangle node" fixes it, as in the example, but is cumbersome. (The bgroup...egroup guards prevent the \tikzset settings from propagating to the rest of the picture, too.) My main question: Why is "every [shape] node" applied after the node options, overriding what is (presumably) the user's choice for that particular object, and is there interest from TikZ developers in changing that default to restore what seems to me to be the more intuitive behavior, that is, applying the "every [shape] node" settings just before the node's optional arguments, so the optional arguments override anything that is applied "globally"? If it would be helpful for me to raise this as an issue on Github, I can do that.

I want to draw a TikZ connector between two cells in a NiceTabular, but the path always appears on top of the rules (hvlines) and the text. If I use \CodeAfter, it's on top, and I can't use \CodeBeforebecause the nodes (i-j) are not recognized. How can I draw this path on the background layer? \documentclass[border = 3pt]{standalone} \usepackage{nicematrix} \usepackage{tikz} \begin{document} \renewcommand{\arraystretch}{1.2} \begin{NiceTabular}{>{\bfseries}*{6}{c}}[ hvlines, corners = NW, ] \RowStyle{\bfseries} & A & B & C & D & E \\ A & & & 1 & 1 & \\ B & & & & 1 & 1 \\ C & 1 & & & & 1 \\ D & 1 & 1 & & & \\ E & & 1 & 1 & & % \CodeAfter \tikz\draw[red, ->] (4-1.east) -| (1-2.south); \end{NiceTabular} \end{document}

How do I modify the \newcommand in the preamble in order for the underlined text to be properly contained by the margins? I got it here: underline omitting the descenders. Also, my code will not compile without the \usepackage{tikz} in the preamble. I don't have a tikzpicture environment in my code. This is bizarre. \documentclass[10pt]{amsart} \usepackage{soul} \usepackage{tikz} \makeatletter \newcommand*{\whiten}[1]{\llap{\textcolor{white}{{\the\SOUL@token}}\hspace{#1pt}}} \DeclareRobustCommand*\myul{% \def\SOUL@everyspace{\underline{\space}\kern\z@}% \def\SOUL@everytoken{% \setbox0=\hbox{\the\SOUL@token}% \ifdim\dp0>\z@ \raisebox{\dp0}{\underline{\phantom{\the\SOUL@token}}}% \whiten{1}\whiten{0}% \whiten{-1}\whiten{-2}% \llap{\the\SOUL@token}% \else \underline{\the\SOUL@token}% \fi}% \SOUL@} \begin{document} In 2007, a team led by Alice Storey analyzed a chicken bone found in El Arenal, Chile, dating it to 1321--1407 CE~---~over a century before Europeans invaded the region, bringing their own chickens.

I want to replicate something as below: Now is my code, but good with the conjunction (the double path's start and end, and the glitch of double), even with line join=round: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture}[line join=round] \coordinate (start) at (0,1.5); \coordinate (end) at (0,0); \draw[magenta] (start) -- ++(3,0) coordinate (doublestart) ++(-.5,-1.5) coordinate (doubleend) -- (end); \draw[cyan,double,double distance=2.5pt] (doublestart) .. controls ++(.25,-.75) and ++(-.3,1) ..

Which ressources (and in which order) would you recommend to (re)learn modern LaTeX for an advanced user that learned LaTeX twenty years ago? I have the impression that many things have changed these past years: NewDocumentCommand, hooks, standard packages that became obsolete, useful things that have been moved to the kernel, utf8 support out of the box, … I thus need to update my LaTeX knowledge, but I am unsure to where to start. A document summarising the changes would be invaluable, but might not exist. An alternative would be recent ressources that assume some familiarities with TeX. If none of these exists, an introductory text will do. The emphasis is on learning things that will be useful in the present, but also in the future. Using experimental methods/packages is not a problem if there are good indications that they will be standard at some point in the future. On the opposite, I would like to avoid learning standard methods/packages that are doomed to be obsolete/deprecated soon. For context: I started to use TeX 20 years ago. At the time I read lshort, The LaTeX Companion (2e) and the TeXbook. This allowed me to became an advanced user of LaTeX and produce documents of far better quality than the one produced by some old professors still using deprecated methods and preamble full of outdated packages. With the years passing I started to add more and more packages to my preamble, as fixltx2e, to finally discover that they became obsolete. A lot has happened these past 20 years and it seems reasonable to start anew in order to unlearn old habits and learn new ones.

I am making a horizontal tree diagram and want the lines (or part of them) to look different in different parts of the diagram. I want to use continuous and dashed lines. Below is an example of what I want to be able to do. I want the lines to be dashed near the root and continuous as they get close to the nodes. The lines can be slightly curved or not, but I specifically do not want them to meet at the root. And a MWE: \documentclass[tikz,border=2mm]{standalone} \usetikzlibrary{trees} \begin{document} \begin{tikzpicture}[ grow=right, level distance=3cm, sibling distance=1.5cm, every node/.style={thick, minimum size=8mm} ] \node {Root} child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, dashed] { node {C} } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, dashed] { node {B} child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, solid] { node {B3} } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, solid] { node {B2} } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, solid] { node {B1} } } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, dashed] { node {A} }; \end{tikzpicture} \end{document}

I would like the baseline of "with nitrogen" to be aligned with the bottom edge of the square shaded gray. The bottom of the tail (descender) in the "g" is currently setting the baseline for the phrase. I tried using \makebox[0pt]. Same edit for the other node. \documentclass[10pt]{amsart} \usepackage{tikz} \begin{document} \begin{tikzpicture}[x=1cm,y=1.5cm] %The key is drawn. The keys in other bar graphs have sample regions that are squares with edge length 0.25 centimeters.

In a tabular environment, text needs to be placed symmetrically besides a drawing: Code: \documentclass[a4paper]{article} \usepackage{graphicx} \begin{document} \begin{tabular}[t]{@{}c@{\hspace{0.5cm}} l@{}} \includegraphics[width=0.9cm]{example-image-a} & \begin{minipage}[t]{10cm} % [t] ensures top alignment line 1\\ line 2\\ \end{minipage} \end{tabular} \end{document} Output: Text is hanging below the image. How to place the image and text side by side symmetrically?

I am trying to replicate the table in the image: As you can see, it has varying number of cells in some of the rows. Sample of what I've tried so far (contains only the rows with varying number of cells): \documentclass{article} \usepackage{tabularx} \begin{document} % 1st table with only 1 cell per row \begin{tabularx}{\textwidth}{|>{\centering\arraybackslash}X|} \hline \textbf{LX -- Left Seat LVO}\\ \end{tabularx} % 2nd table with 4 cells per row \begin{tabularx}{\textwidth}{|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|} \hline \textbf{Weights/CG} & A320 & A330 & A350\\ \end{tabularx} % 3rd table with one cell per row \begin{tabularx}{\textwidth}{|>{\centering\arraybackslash}X|} \hline Profile A: Takeoff Perf: FlySmart\\ \end{tabularx} % 4th table with 5 cells per row \begin{tabularx}{\textwidth}{|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|>{\raggedleft\arraybackslash}X|} \hline \textbf{Weights/CG} & A320 CEO & A320 NEO & A330 & A350\\ \hline \end{tabularx} \end{document} I have tried to concatenate tabularx environments because I would like it to fill the whole page laterally, but the problem is that those are different tables, which creates two problems: There are tiny (but still noticeable) gaps in the borders of the cells right after every \end{tabularx} If the "whole table" doesn't fit in the page it is split by one of the \begin{tabularx} instead of filing the page. Is it possible to create everything in a single table? Are there other table packages that you would recommend? Thank you very much in advance

I'm just curious why drawing a line with edge doesn't consider option double.
