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. How can I correctly parse the input so that commands keep their arguments, while still processing the content recursively? \documentclass[8pt]{article} \usepackage[ paperwidth=28cm, paperheight=4cm, margin=0.5cm ]{geometry} \usepackage{xparse} \ExplSyntaxOn \NewDocumentCommand{\Brackets}{m} { \brackets_process:n {#1} } \cs_new_protected:Npn \brackets_process:n #1 { \tl_map_inline:nn {#1} { \brackets_case:n {##1} } } \cs_new_protected:Npn \brackets_case:n #1 { \tl_if_single:nTF {#1} { \tl_if_head_is_group:nTF {#1} { % Es un grupo \BracketsGroup:n {#1} } { % Es una lista \token_if_cs:NTF #1 { \BracketsCommand:n {#1} } % Es un comando { \token_if_space:NTF #1 { [\c_space_tl] } { \BracketsToken:n {#1} } } % Es un caracter } } { { \BracketsGroup:n {#1} } } } \cs_new_protected:Npn \BracketsGroup:n #1 { \brackets_process:n {#1} } \cs_new_protected:Npn \BracketsCommand:n #1 { #1 } \cs_new_protected:Npn \BracketsToken:n #1 { \str_case:nnF {#1}{{$}{$}{^}{^}{_}{_}}{ [#1] } } \ExplSyntaxOff \begin{document} \Brackets{Text \textbf{textbf \textit{textit} text } text {text {group}} text $ x^{1+1}+2x+4$ $\frac{1}{2} \sqrt[3]{x}$ text. {{Text}} } \vspace{5mm} Expected:\\ [T][e][x][t] \textbf{[t][e][x][t][b][f][ ]\textit{[t][e][x][t][i][t]}[ ][t][e][x][t]}[ ][t][e][x][t][ ]{[t][e][x][t][ ]{[g][r][o][u][p]}}[ ][t][e][x][t][ ]$ [x]^{[1][+][1]}[+][2][x][+][4]$[ ]$\frac{[1]}{[2]} \sqrt[{[3]}]{[x]}$[ ][t][e][x][t][.][ ]{{[T][e][x][t]}} \end{document} Expected behavior:

There is an equation that I would like to break and align as follows: ( in the second line and - in the third line should be aligned the same way that [ in the first line and + in the second line are, which requires aligning on more than one 'level' if level is the correct term. Intuitively, it would work as shown in the MWE, just with && not commented out: & for the first 'level' and && for the second one. (The concept could be extended by &&& for the third one and so on.) \documentclass{article} \usepackage{amsmath} \begin{document} \begin{align} E_\mathrm{kinetic}=\frac{1}{2}&\left[m_\mathrm{1}\left(v_\mathrm{1}-v_\mathrm{2}\right)^2\right.\notag\\ &\left.+m_\mathrm{2} % && \left(v_\mathrm{3}+...+...+...+...+a\omega_\mathrm{1}\right.\right.\notag\\ % && -\left.\left.b\omega_\mathrm{2}-...-...-...-...-v_\mathrm{4}\right)\right] \end{align} \end{document}

The result of render also looks like the "hello." after \[hello\] is unusually squashed into the green box.

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}

Hi I'm working on a beamer presentation and I already have a somewhat modified \titlepage and setting, to this I would ideally need to add an image to the footline; however, after a few experiments and editing the prompt I already worked on I cannot quite achieve what I want... The problem is for one that the image seems to overlay the original footline instead of being the only element there and is poorly cropped; additionally, the page numbers are not visible on the \titlepage although I set them up as before. Lastly, I wish to have a very small margin from the bottom, left, and right to don't show the image as it is completely framed to the bottom of the slide. Thanks!

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.

I am trying to understand the differences between the fullpage package (e.g. \usepackage[cm]{fullpage}) and the geometry package for setting page margins. From what I see, both seem to adjust margins, but I am not sure: In which situations is it appropriate to use fullpage? When should I prefer geometry instead? Are there any limitations or drawbacks of fullpage compared to geometry? Is one of them considered best practice today? For example, is there any reason to write: \usepackage[cm]{fullpage} instead of: \usepackage[a4paper, margin=2cm]{geometry} I would appreciate a clear explanation of the differences and recommendations for typical use cases.

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}

Let me know if this question is too broad and I will try to narrow it. So, I am trying to learn expl3, and I am using Gemini, a code project and various articles as my tools. The main article I've been reading is this one, and it has helped. So has Gemini. Gemini is making a lot of mistakes and causing confusion, but for some of the basics, it has helped me a lot (I noticed my ability to understand the linked-to article improved after talking with Gemini). But now, Gemini is seemingly no longer able to teach me, because I've reached the end of its more-accurate-than-not region. It cannot precisely and rigorously explain how TeX does macro expansion. As a result, I do not understand it. Gemini seems to have a bias to unnecessarily utilize expansion signatures and use/eval functions (and therefore it has to utilize more _protected and \exp_not:n functions), which is really making a mess of its code. The code compiles correctly, but with massive amounts of unnecessary pre-expansion. And that is thusly making me really confused about when and why we change the order of expansion. [BTW, perhaps unneccesary expansion combined with nonetheless relatively advanced code is a good indicator of AI-written LaTeX?] So, for context, here is the extent of my understanding till now, taken from the linked-to article: \newcommand{\cmda}{abcd} \uppercase{abcd\cmda} %ABCDabcd So, in this example, we're shown that using \uppercase here does NOT produce the output ABCDABCD. This is explained through the fact that \uppercase is acting on letters, and leaves control sequences unchanged. Now, \cmda is control sequence, but its defintion is a string of letters. So, if we could pre-expand \cmda, then we could get the result ABCDABCD. The article explains two ways to do this, but I'm more interested in why we have to do this in the general case. And I wonder if the above example gives me a general understanding of when expansion is needed. So, when we have a function and we DON'T need to expand it, is it simply because the control sequence is "readable/expandable" by that function, and the function is thusly able to act on its definition? My current understanding can be summed up as this: If you want the function to act on a control sequence's definition, and if the function doesn't expand its input for you, you have to expand the input for it. How to expand depends on how many layers you want to expand, and what the control sequence is (function or variable). Knowing when to pre-expand (and knowing when to protect from pre-expansion) thus reduces to knowing which functions don't, and do, expand for you. I have a feeling this is insufficient, however. Like it isn't a fully general explanation. And even if it is general, it seems imprecise. I would like to be able to break things down into the eyes-vs-mouth-vs-stomach analogy and understand how TeX parses the text and when it expands each component thereof. I currenly have an idea of the mouth expanding everything with a default order, and then the text reaches the stomach fully expanded, and there it gets converted by the PDF engine into points on paper. Understanding this pipeline at high level of detail and rigor would make everything a lot simpler to me. The core idea of expansion and the ordering thereof is simple, but the devil is in the details.
