I looked into pgfcircbipoles.tex and found values like \ctikzvalof{bipoles/capacitor/height}, but this seems to be factors (?). How do I draw a line as long and as wide as a capacitor line? \documentclass[margin=5pt]{standalone} \usepackage{circuitikz} \begin{document} %\def\t{\ctikzvalof{sources/symbol/thickness}}% test %\def\t{\ctikzvalof{bipoles/cuteswitch/thickness}}% test \def\t{\ctikzvalof{bipoles/thickness}}% test \def\h{\ctikzvalof{bipoles/capacitor/height}}% test \begin{circuitikz} \draw (0,0) to[capacitor, name=A] (2,0) to[R] (4,0); \draw[red, line width=\t, opacity=0.5] (A.north east) node[above, inner sep=0.5pt]{\t=t} -- +(0,-\h) node[near start, right]{\h=h}; \end{circuitikz} \end{document}

I created a matrix by this code $ A_{n+1}= \begin{pmatrix} a & \begin{tabular}{ccccc} 0 & 0 & \ldots & 0 & 0 \\ \end{tabular} & 1\\ \begin{tabular}{c} 0\\ \vdots\\ \end{tabular} & A_n & \begin{tabular}{c} 0\\ \vdots \end{tabular} \\ 1 & \begin{tabular}{ccccc} 0 & 0 & \ldots & 0 & 0 \\ \end{tabular} & a\\ \end{pmatrix} $ But I don't like the result because the margin between the "a" and the first "0" in the first line is too large. I guess it's due to the tabular environment. Anyway to improve it?

In the following toy example, I would like to use __ and ^^ instead of - and .. Is it possible? \documentclass[varwidth, border = 3pt]{standalone} \NewDocumentCommand{\hyperseq}{ m e_ e^ e- e. }{% $% {}% \IfValueT{#4}{_{#4}}% \IfValueT{#5}{^{#5}}% #1% \IfValueT{#2}{_{#2}}% \IfValueT{#3}{^{#3}}% $ } \begin{document} \hyperseq{u} \hyperseq{u}_{1} \hyperseq{u}_{1}^{2} \hyperseq{u}_{1}^{2}-{3} \hyperseq{u}_{1}^{2}-{3}.{4} \hyperseq{u}-{3}.{4} \end{document}

My doubt deals with the wrapping of text around figures in LaTeX. When I place a wrapped figure at the bottom of a page—like in the case described by the following code: \documentclass[11pt]{article} \usepackage{wrapfig} \usepackage{graphicx} \usepackage{notomath} \usepackage{microtype} \begin{document} \section*{A section} Lorem ipsum dolor sit amet, consectetur adipiscing elit.

I know that this can be achieved by moving the figure in a previous part of the code, but I would prefer to avoid this solution.

I am writing a software which is supposed to take a set of triangles, where some of the members of the set are capable of partitioning one another, and performing all possible partitioning. I built Lua functions which are capable of detecting and performing most intersections. Unfortunately, there appears to be a particular case which is causing me some trouble. For example, consider the following diagram where I deliberately used a complicated case to show that my algorithm works in most cases. [Unfortunately, you need to run the GitHub version of the package :-(. This is because I want to fix this bug and write new documentation before making another release.] \documentclass[tikz,border=1cm]{standalone} \usepackage{lua-tikz3dtools} % https://github.com/Pseudonym321/TikZ-Animations/tree/master1/TikZ/lua-tikz3dtools \begin{document} \pgfmathsetmacro{\i}{-pi/4} \begin{tikzpicture} \useasboundingbox[scale=2] (-1,-1) rectangle (1,1); \setobject[ name = {T} ,object = { matrix_multiply( matrix_multiply( euler(pi/2,pi/3,7*pi/6) ,translate(0,0,-5) ) ,matrix_multiply( { {1,0,0,0} ,{0,1,0,0} ,{0,0,1,0} ,{0,0,0,1} } ,matrix_multiply(xscale(1),yscale(1)) ) ) } ] \setobject[ name = {I} ,object = { matrix_inverse(T) } ] \foreach \j in {2,3,1,0}{ \appendsurface[ ustart = {-2} ,ustop = {2} ,usamples = {2} ,vstart = {-2} ,vstop = {2} ,vsamples = {2} ,transformation = {matrix_multiply(euler(\j+\i,2*\j,\j),T)} ,x = {u} ,y = {v} ,z = {\j/10} ,fill options = { preaction = { \ifnum\j=0 fill = red \fi \ifnum\j=2 fill = green \fi \ifnum\j=1 fill = yellow \fi \ifnum\j=3 fill = blue \fi ,fill opacity = 0.6 } ,postaction = { draw = black ,ultra thin ,line join = round ,line cap = round } } ,filter = { abs(matrix_multiply(A,I)[1][3])<1.01 and abs(matrix_multiply(B,I)[1][3])<1.01 and abs(matrix_multiply(C,I)[1][3])<1.01 and abs(matrix_multiply(A,I)[1][2])<1.01 and abs(matrix_multiply(B,I)[1][2])<1.01 and abs(matrix_multiply(C,I)[1][2])<1.01 and abs(matrix_multiply(A,I)[1][1])<1.01 and abs(matrix_multiply(B,I)[1][1])<1.01 and abs(matrix_multiply(C,I)[1][1])<1.01 } ] } \appendsolid[ ustart = {-1} ,ustop = {1} ,usamples = {2} ,vstart = {-1} ,vstop = {1} ,vsamples = {2} ,wstart = {-1} ,wstop = {1} ,wsamples = {2} ,transformation = {T} ,x = {u} ,y = {v} ,z = {w} ,fill options = { preaction = { fill = gray ,fill opacity = 0.5 } ,postaction = { draw = black ,ultra thin ,line join = round ,line cap = round } } ] \displaysegments \end{tikzpicture} \end{document} Gif: This is a picture of four planes intersecting, clipped by a cube. Currently, for the clipping (filtering) to work, projective transformations currently do not work, only affine ones do. This will eventually be fixed, of course. So it works, and all is fine and well - why are we here? Well, in the above diagram, each plane is offset by a small (and in each case different) translation. If this translation weren't there (and even with it there sometimes), we are faced with two triangles, which are capable of partitioning one another, which are not partitioned. I have the sense (possibly wrong) that this case wherre partitioning fails is when two triangles are non-coplanar, and meet at a vertex with the rest of their bodies visually passing through each other. It appears that my functions are not detecting and/or are not partitioning this case. For example, without the translation (it's a small difference, look at the z key), we get the following horrible graphic. \documentclass[tikz,border=1cm]{standalone} \usepackage{lua-tikz3dtools} % https://github.com/Pseudonym321/TikZ-Animations/tree/master1/TikZ/lua-tikz3dtools \begin{document} \pgfmathsetmacro{\i}{-pi/4} \begin{tikzpicture} \useasboundingbox[scale=2] (-1,-1) rectangle (1,1); \setobject[ name = {T} ,object = { matrix_multiply( matrix_multiply( euler(pi/2,pi/3,7*pi/6) ,translate(0,0,-5) ) ,matrix_multiply( { {1,0,0,0} ,{0,1,0,0} ,{0,0,1,0} ,{0,0,0,1} } ,matrix_multiply(xscale(1),yscale(1)) ) ) } ] \setobject[ name = {I} ,object = { matrix_inverse(T) } ] \foreach \j in {2,3,1,0}{ \appendsurface[ ustart = {-2} ,ustop = {2} ,usamples = {2} ,vstart = {-2} ,vstop = {2} ,vsamples = {2} ,transformation = {matrix_multiply(euler(\j+\i,2*\j,\j),T)} ,x = {u} ,y = {v} ,z = {0} ,fill options = { preaction = { \ifnum\j=0 fill = red \fi \ifnum\j=2 fill = green \fi \ifnum\j=1 fill = yellow \fi \ifnum\j=3 fill = blue \fi ,fill opacity = 0.6 } ,postaction = { draw = black ,ultra thin ,line join = round ,line cap = round } } ,filter = { abs(matrix_multiply(A,I)[1][3])<1.01 and abs(matrix_multiply(B,I)[1][3])<1.01 and abs(matrix_multiply(C,I)[1][3])<1.01 and abs(matrix_multiply(A,I)[1][2])<1.01 and abs(matrix_multiply(B,I)[1][2])<1.01 and abs(matrix_multiply(C,I)[1][2])<1.01 and abs(matrix_multiply(A,I)[1][1])<1.01 and abs(matrix_multiply(B,I)[1][1])<1.01 and abs(matrix_multiply(C,I)[1][1])<1.01 } ] } \appendsolid[ ustart = {-1} ,ustop = {1} ,usamples = {2} ,vstart = {-1} ,vstop = {1} ,vsamples = {2} ,wstart = {-1} ,wstop = {1} ,wsamples = {2} ,transformation = {T} ,x = {u} ,y = {v} ,z = {w} ,fill options = { preaction = { fill = gray ,fill opacity = 0.5 } ,postaction = { draw = black ,ultra thin ,line join = round ,line cap = round } } ] \displaysegments \end{tikzpicture} \end{document} It appears that there is a problem for triangles which are capable of partitioning one another, which also coincide at a single vertex.

However, the \hspace{-2cm} and \vspace{-2cm} commands don't seem to work as expected. \documentclass{beamer} \NewDocumentCommand\StepFrame{m m m m m o o} { \begin{frame}{#4 Step #2/#3} #5 \fbox{\includegraphics[width=\textwidth]{IMAGES/Set#1/Step#2.png}} \IfNoValueF{#6} { \llap{ \hspace{-2cm} % Horizontal offset does not work \vspace{-2cm} % Vertical offset does not work \includegraphics[width=0.4\textwidth]{IMAGES/Set#6/Step#7.png} } } \end{frame} } \begin{document} \StepFrame{2}{1}{54}{Vitis}{Click Set Workspace} \StepFrame{2}{2}{54}{Vitis}{image description missing} \StepFrame{2}{3}{54}{Vitis}{image description missing} \StepFrame{2}{4}{54}{Vitis}{image description missing} \StepFrame{2}{5}{54}{Vitis}{image description missing}[2][5b] \end{document}

Is there a package-like way to rotate the "component-labels" as like the others in normal alignment? For example: \documentclass[margin=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european resistors] %\ctikzset{label/align=rotate} % something other... \draw[] (0,0) to[sinusoidal voltage source, l=$u(t)$] (0,3) to[vR=$R$, f>^=$i(t)$] (4,3) to[L=$L$] (4,0) to[ecapacitor=$C$] (0,0); % How to rotate component-label? \draw[blue] (3,0) to[thermistor ntc, *-*] (3,3); \end{circuitikz} \end{document} PS: Then I noticed that 'ϑ' doesn't turn blue when I say \draw[blue]; that's probably not intentional (?). €dit (side problem solved): I would have need to say \draw (3,0) to[thermistor ntc, color=blue, *-*] (3,3); as mentioned from @kabenyuk.

In other words, how can I draw the dashed red bond in the following figure? I know that the following workaround works: \documentclass{standalone} \usepackage{chemfig} \begin{document} \chemfig{ A?[a]-[:30,2,,,color=red]B-[:-90]C(-[:150,2,,,color=white,line width=2pt])-[:150,2,,,line width=1.2pt]D?[a] } \end{document} However, this method requires drawing the bonds layer by layer, and in some situations it becomes difficult—or even impossible—to control the drawing order of the bonds. It also seems that chemfig itself does not provide any mechanism for rendering overlapping bonds. For example, even in the package documentation, cases like the one below show no explicit handling of overlapping bonds:

I would like to create a randomized enumerate list whose items may contain lstlisting environments. So far, I can successfully randomize ordinary items, but items containing a lstlisting environment break the mechanism. I have a workaround, but it forces all listings to stay in fixed positions, which defeats the purpose of randomization. I would like all items—including those containing listings—to be included in the shuffle performed by \additem. Here is an example of my 'workaround' solution. \documentclass{article} % ---------- Packages ---------- \usepackage[french]{babel} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{lmodern} \usepackage{enumitem} \usepackage{xcolor} \usepackage{listings} % ----------- Style Matlab ----------- \lstdefinestyle{stylematlab}{ language=Matlab, basicstyle=\ttfamily\small, keywordstyle=\color{blue}, commentstyle=\color{green!60!black}, numbers=left, numberstyle=\tiny, stepnumber=1, frame=single } % ----------- Randomized items ----------- \usepackage{pgffor} \usepackage{pgf} \usepackage{xparse} \ExplSyntaxOn % Sequence storing the items \seq_new:N \g_myitems_seq % Add item \NewDocumentCommand{\additem}{m}{ \seq_put_right:Nn \g_myitems_seq {#1} } % Shuffle and typeset \NewDocumentCommand{\shuffleitems}{}{ \pgfmathsetseed{\number\pdfrandomseed} \seq_shuffle:N \g_myitems_seq \begin{enumerate} \seq_map_inline:Nn \g_myitems_seq {##1} \end{enumerate} } \ExplSyntaxOff \begin{document} Indiquer si chaque affirmation est vraie (V) ou fausse (F). % ---- Ajout des items ---- \additem{ \item En programmation numérique, une complexité algorithmique en $\mathcal{O}(n^2)$ est toujours préférable à une complexité en $\mathcal{O}(n \ln n)$. } \additem{ \item Les fonctions anonymes en \textsc{Matlab} ne peuvent pas être passées comme arguments à d'autres fonctions. } \additem{ \item En général, dans un problème d’optimisation, une solution optimale locale est garantie d’être aussi une solution optimale globale. } % ---- Mélange des items ---- \shuffleitems % ---- Items supplémentaires (non randomisés) ---- \begin{enumerate}[start=4] \item Exemple avec listing Matlab : \begin{lstlisting}[style=stylematlab] f = @(x) x.^2 + 1; x = -5:0.1:5; plot(x,f(x)) \end{lstlisting} \end{enumerate} \end{document} Items containing lstlisting do not behave well inside the token storage. They seem to prevent the shuffle from working properly. My temporary workaround is to keep such items outside the randomized block, but this defeats the point. Is there a way to fully integrate items containing lstlisting into the randomization process performed by \additem, without switching to the exam class and eventually exam-randomizechoices?

This time from me a question around a set of issues that can maybe actually be resolved in the near future, even though more likely via code changes than just configuration, but I am asking here first for some insights... I have a document with a rather special font, a font has been working well with all of its features on modern webbrowsers and also e.g. on Mac since at least 2021, and I am using XeLaTeX to render it, where it also essentially works. But since apparently things gravitate towards evolving rather LuaLaTeX than XeLaTeX, I wanted to see if I can just switch to LuaLaTeX, also since that had worked fine for me with at least one "normal" font in a somewhat simpler setup. Well, this seems to fail in various ways. Here is some source that is close enough to my real use case to show them all: \documentclass{article} \usepackage[english]{babel} \usepackage{geometry} \usepackage{fontspec} \geometry{ twoside=true, paperwidth=4.37in, paperheight=7in, top=0.263in, bottom=0.613in, inner=0.64in, outer=0.5in, bindingoffset=0cm, } \AddToHook{normalfont}{ \fontdimen2\font=0.25em % interword space \fontdimen3\font=0.3em % interword stretch \fontdimen4\font=0.2em % interword shrink \fontdimen7\font=0.1em % extra space } % https://jack-daw.com/fonts/jackwrite.zip \setmainfont{Jackwrite.ttf}[ %Renderer=HarfBuzz, Scale=MatchLowercase, FakeBold=0.001, ] \begin{document} \noindent Cynthia was secretly peeking over Jack’s shoulder as he started to write: \vspace{2.2mm}\noindent All experience in life is personal. Life as experienced by everybody is a bit like a movie. Things are happening inside and outside of you. Unlike in a movie, you can influence some of it. But most of it is just happening independently of what you desire. Nobody ever looked at the world consistently from that perspective. The personal, individual perspective. How everybody experiences life. Obviously this is not the only viable perspective. But a fascinating one. With lots of potential to explore. Way more than it may seem. What’s in it for you? Well, many things in the world are simpler from this perspective. A lot of things should make sense that previously seemed hard to relate. This can be useful, make happy. It hardly ever makes things more convoluted. So let me just start. \end{document} Here is the output with XeLaTeX: Here with LuaLaTeX and HarfBuzz renderer: And the same but without FakeBold, since it "blurs" other issues: And here just as an example for basic usage outside TeX in TextEdit on Mac: Obviously, FakeBold behaves differently. I noticed that with XeLaTeX, there seems to be a discrete jump between no FakeBold and a very low values like FakeBold=0.001 and then things appear to stay roughly constant until you get to something around FakeBold=3, while with LuaLaTeX (HarfBuzz) the values seem to have a more linear effect. I can live with that, and seems rather to be an issue or limitation with XeLaTeX than LuaLaTeX. But worse is, of course, how the paragraphs are rendered overall. In principle, since XeLaTeX is apparently also based on HarfBuzz, you would expect the same result. The space between words shrinks much smaller with LuaLaTeX. Also, which is not immediately obvious, with LuaLaTeX the width of paragraphs is slightly larger, which I could presumably correct by reducing the nominal width, but that seem to be rather a workaround. About the font (download it here): It is based on a subset of the glyphs from Fredrick Brennan’s TT2020 Font, a monospaced typewriter font with the special feature of rendering each character as 9 slightly different glyphs with tiny "typewriter-like" defects, described who it works by him here. What I did for the Jackwrite font was to add kerning individually between each character pair, actually between all 9 variants of it, which means that there is quite a bit more kerning info in the font than usual. (The Node renderer of LuaLaTeX fails to get the kerning right, or rather gets it right in only maybe 95% of cases, I have not investigated further there.) Added same day in evening: I noticed that what I wrote about the discrete jump for FakeBold with XeLaTeX is not true, was an "illusion", where I viewed it (TexShop on Mac) at lower magnification the fake bold shows more strongly than at higher magnification. Here is a comparison for the following source (plus use corresponding renderers when using LuaLaTeX) \documentclass{article} \usepackage{fontspec} \begin{document} \Huge \setmainfont{Jackwrite.ttf} XeLaTeX\par \setmainfont{Jackwrite.ttf} yyyyyyyyy\par \setmainfont{Jackwrite.ttf}[FakeBold=0.001] yyyyyyyyy 0.001\par \setmainfont{Jackwrite.ttf}[FakeBold=1] yyyyyyyyy 1\par \setmainfont{Jackwrite.ttf}[FakeBold=2] yyyyyyyyy 2\par \setmainfont{Jackwrite.ttf}[FakeBold=3] yyyyyyyyy 3\par \setmainfont{Jackwrite.ttf}[FakeBold=4] yyyyyyyyy 4\par \setmainfont{Jackwrite.ttf}[FakeBold=5] yyyyyyyyy 5\par \setmainfont{Jackwrite.ttf}[FakeBold=10] yyyyyyyyy 10\par \setmainfont{Jackwrite.ttf}[FakeBold=20] yyyyyyyyy 20\par \end{document} Thus except for the difference for 0.001, pretty much the same result. (The difference for the "10" with XeLaTeX is presumably because, due to some different internas, it chose another one of the 9 glyphs for "1" than with LuaLaTeX.) And, I presume some tiny "spikes" the glyphs are amplified a lot when using large values for FakeBold. That is OK for my use case, and probably better fixed if needed in the font itself, while a more robust algorithm for FakeBold would, of course, in principle be desirable. Leaves the issue with different spacing and paragraph widths...

I have mostly been a Plain TeX user, but for collaboration purposes find myself having to use LaTeX. In the LaTeXed book I am working on, I would like to have headers as described in the fourth paragraph of page 260 of the TeXbook: "On left-hand pages, the section number in the headline is supposed to reflect the situation at the top of the page, as we have discussed, but on right-hand pages it is supposed to refer to the bottom of the page." Knuth then goes on to give the Plain TeX solution to this problem: \def\beginsection #1. #2. {\mark{\currentsection \noexpand\else #1} \sectionbreak \leftline{\sectionfont #1. #2} \mark{#1\noexpand\else #1} \def\currentsection{#1} \nobreak\smallskip\noindent} \def\currentsection{} % the current section number The \rightheadline macro can then use \iftrue\botmark\fi, and the \leftheadline macro can say \expandafter\iffalse\topmark\fi. I won't claim to fully understand how everything works here, but I successfully adapted this code before for my Master's thesis that I wrote in Plain TeX several years ago. (EDIT. I looked through the code for my thesis again, and found that I only used one mark, ignoring Knuth's warning, and sure enough there is a mistake in the header numbering in my thesis. But I do trust that this code in the TeXbook works, and of course TAOCP doesn't have any header numbering issues that I know of.) My question is, what is the best way to get this same behaviour in LaTeX using the fancyhdr package? I have the following MWE (it feels wrong to use \rightmark on a left-hand page, but if I use \leftmark I get the a blank, presumably because I haven't defined a chapter title yet). \documentclass[10pt]{book} \usepackage{fancyhdr, lipsum, extramarks} \pagestyle{fancy} \fancyhf{} \fancyhead[LE]{\thepage} \fancyhead[RE]{\rightmark} \fancyhead[LO]{\rightmark} \fancyhead[RO]{\thepage} \begin{document} \section{First section} \lipsum[1-7] \section{Second section} \lipsum[1-5] \section{Third section} \lipsum[1-2] \goodbreak \section{Fourth section} \lipsum[1-2] \end{document} It produces the following four pages, which I believe should illustrate the full complexity of the problem. Page 1 is correct since the section at the bottom of the page is still 0.1. Page 2 is incorrect because the section at the top of the page is still 0.1, but it says 0.2 Page 3 is correct since the section at the bottom of the page is 0.3. Page 4 is correct since section 0.4 starts at the top of the page, (but it's correct by accident, since there is no section 0.5). How would one fix this MWE to get the headers to say 0.1, 0.1, 0.3, and 0.4? I am not above janky things like redefining LaTeX primitives, but I'd prefer the least invasive solution. I thought the extramarks package might be what I need, but I wasn't able to figure out how to make it work. Thanks in advance! EDIT. It seems, following @cfr's comments, that out of the box package solutions might not be good enough to solve this issue. I suspect that one might have to redefine LaTeX's \beginsection code (or whatever its analogue is) to emit two marks as in the TeXbook example. I'll look into this myself once I have some free time tomorrow or later in the week, but if anyone beats me to it I'd gladly accept the answer, of course!

I am trying to define a command that draw TikZ pictures whose baseline is centered, with an optional argument to modify the y-coordinate of the baseline. I came up with the following code. When the optional parameter is provided, it behaves as expected. However, when no parameter is provided, it doesn't do what I expected: instead, it seems to pick the top as the baseline. If I manually replace the parameters, it behaves as expected. What is it that I am missing? \documentclass{article} \usepackage{tikz} \NewDocumentCommand{\tikzpic}{mO{}}{ \begin{tikzpicture}[ baseline=(base), ] #1 \IfNoValueTF{#2} {\coordinate (base) at (current bounding box.center);} {\coordinate (base) at (0,#2);} \end{tikzpicture} } \begin{document} command \tikzpic{ \draw (0,0) rectangle (1,1); } \medbreak expected behaviour \begin{tikzpicture}[ baseline=(base), ] \draw (0,0) rectangle (1,1); \coordinate (base) at (current bounding box.center); \end{tikzpicture} \end{document}

I have the following forest setup that allows me to add citations to the bottom of each leaf node of my taxonomical diagram: \documentclass[twocolumn]{article} \usepackage{array} \usepackage{tikz} \usepackage{forest} % tikz setup \newcolumntype{C}[1]{>{\centering}p{#1}} \forestset{% cite/.style={label=below:{\cite{#1}}}, concept/.style={% anchor=center, rounded corners, draw=black, fill=blue!20, l sep'=20pt, s sep'=2.5pt, align={C{2cm}}, font=\small, }, } \begin{document} \begin{figure*} \centering \begin{forest} for tree={concept}, [Segmentation [Classical [Colour \& intensity, cite={entry01}] [Clustering, cite={entry02}] ] [Deep [Downstream CNN, cite={entry03}] [CED, cite={entry04}] [GAN, cite={entry05}] [Transformers, cite={entry06}] ] ] \end{forest} \end{figure*} \bibliographystyle{unsrt} \bibliography{Literature} \end{document} This works fine (aside from some vertical alignment issues), as seen in the above picture. However, if I include several references, the picture becomes unreadable: \begin{figure*} \centering \begin{forest} for tree={concept}, [Segmentation [Classical [Colour \& intensity, cite={entry01,entry07,entry08,entry09,entry10,entry11,entry12,entry13,entry14,entry15,entry16,entry17,entry18}] [Clustering, cite={entry02,entry19,entry20,entry21,entry22,entry23,entry24,entry25,entry26,entry27,entry28,entry29,entry30}] ] [Deep [Downstream CNN, cite={entry03}] [CED, cite={entry04}] [GAN, cite={entry05}] [Transformers, cite={entry06}] ] ] \end{forest} \end{figure*} In this specific case, this would be solvable using citation ranges (like [1-4] instead of [1],[2],[3],[4]), but this isn't always possible in general. Is there a way to make forest automatically wrap the citation text into multiple lines so each label fits within the width of its leaf node?

Generally, I don't include many links in my PDFs. Until now I’ve never had problems with \href from the hyperref package: when the URL contains % characters, I escape them using \% and everything works fine. I suppose to have a URL with many % https://www.emathhelp.net/calculators/calculus-2/series-calculator/?f=n%5E%280.9999%29*%281%2F%28n-2%29-1%2F%28n-1%29%29&var=n&a=3&b=%2Binf \documentclass[12pt]{article} \usepackage{hyperref} \begin{document} \href{https://www.emathhelp.net/calculators/calculus-2/series-calculator/?f=n\%5E\%280.9999\%29*\%281\%2F\%28n-2\%29-1\%2F\%28n-1\%29\%29&var=n&a=3&b=\%2Binf}{t} \end{document} I put for every % the symbol \ thus the \href work correctly. If I use the original link provides me with an incomplete URL because the first % acts as a comment (see the picture below). But if a URL contains, for example, twenty % characters, what is the correct way to handle them so that \href works properly without put manually twenty \?

Is there a circuitikz-package-like way, to get a transistor like this? This means where the lines of the emitter and collector start at the same point. \documentclass[margin=5mm]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[] \draw (0,0) node[npn](T){}; \draw (T.B) node[left]{B} (T.C) node[above]{C} (T.E) node[below]{E}; \end{circuitikz} \end{document}

I'm using the \enquote command from csquotes to automatically produce appropriate quotation marks. I have also specifically enabled the "middle quotes" so that if there's a paragraph break inside a quotation then the new paragraph starts with an extra opening quote. But this is producing unwanted middle quotes in the verse environment. Here is an example: \documentclass{book} \usepackage[english=american]{csquotes} \DeclareQuoteStyle[american]{english} {\textquotedblleft} [\textquotedblleft] {\textquotedblright} {\textquoteleft} [\textquoteleft] % this is redundant for the example but I kept it for symmetry {\textquoteright} \begin{document} \enquote{Voila!\\ In view, a humble vaudevillian veteran, cast vicariously as both victim and villain in the vicissitudes of fate. This visage, no mere veneer of vanity, is but a vestige of the \enquote{vox populi} now vacant, vanished.} \begin{verse} \enquote{Mary had a little lamb,\\ Its fleece was white as snow\\ And everywhere that Mary went\\ The lamb was sure to go. It followed her to school one day,\\ That was against the rule;\\ It made the children laugh and play,\\ To see a lamb at school.} \end{verse} \end{document} I only want the first line of each stanza to start with opening quotes, just like the prose, but as it stands every line gets one. So in the output as follows, I don't want the highlighted quotation marks to appear: In case it matters, I would like the solution to also work with the more advanced verse environment from the memoir class. Tangential issue: I want to also be able to use just one \enquote in case the same quotation changes from prose to verse (or vice versa), but I don't see how to nest the \enquote and verse appropriately for that (unless there is prose both before and after the verse).

I have the following LaTeX code (using amsmath and amssymb): \documentclass[12pt]{article} \usepackage{amsmath,amssymb} \begin{document} \[ \sum_{n=1}^{+\infty} \frac{\left(1 + \sin \frac{1}{n^2}\right)^{n^2}}{n^x} \] Consider the general term: \[ a_n = \frac{\left(1 + \sin \frac{1}{n^2}\right)^{n^2}}{n^x} = \frac{\left(1 + \dfrac{1}{\frac{1}{\sin \frac{1}{n^2}}}\right)^{n^2}}{n^x} = \frac{\Biggl[\left(1 + \dfrac{1}{\frac{1}{ \sin \frac{1}{n^2}}}\right)^{n^2}}{n^x} \] \end{document} In the last line I used \Biggl[ hoping to make the square bracket as tall as a \left[ ...\right] delimiter. But \Biggl[ does not match the height of \left[ in my expression: the bracket doesn’t scale quite as much, especially when the content inside is very tall (because of exponents, fractions, etc.). My questions are: Is there a “size command” (\big, \Big, \bigg, \Bigg, or something else) for square brackets that produces exactly the same height as \left[ ...\right] in all cases? If not, what is the best practice to get “manual brackets” that are almost as tall as \left[ ...\right], but without using \left/\right (e.g., to avoid weird spacing or other layout issues)? Are there advanced TeX tricks (or uses of font parameters) to “force” bracket sizes even larger than standard \Bigg?

I have a table of equations where I'm including the section where that equation was introduced. I'd like to align the sections on the decimal marker between the section and the subsection. Here's an example of what I mean: \documentclass{article} \usepackage{siunitx} \begin{document} \section{Section}\label{sec}\[a^2+b^2=c^2\] \stepcounter{subsection} \subsection{Subsection}\label{subsec}\[E=mc^2\] \addtocounter{subsubsection}{2} \subsubsection{Subsubsection}\label{subsubsec}\[F=ma\] \begin{tabular}{ l S[table-format=1.2, table-align-text-after=false] l } \hline Equation & {Section} & Section \\\hline $a^2+b^2=c^2$ & 1 & 1 \\ $E=mc^2$ & 1.2 & 1.2 \\ $F=ma$ & 1.2{.3} & 1.2.3 \\\hline $a^2+b^2=c^2$ & \ref{sec} & \ref{sec} \\ $E=mc^2$ & \ref{subsec} & \ref{subsec} \\ $F=ma$ & \ref{subsubsec} & \ref{subsubsec} \\\hline \end{tabular} \end{document} If I left align the column (3rd column), then it's too far to the left, relative to the "Section" header. siunitx can align on the decimal like I want, but it doesn't see the marker at all (2nd column, bottom half). And if I manually enter the section numbers, I still have to protect the subsubsection from being seen (2nd column, top half). Is there a way to have the entries aligned on the first decimal point (2nd column, top half) but have \ref produce the section numbers (bottom half)? (Note that this will use booktabs and hyperref, but those do not seem necessary for the question at hand.)

I have been using DocumentMetadata with tocloft in pdflatex without setbacks for more than two years. However, something changed with the most recent updates. Currently the code gives warning tocloft.sty: warning: 1156: \@starttoc has already been redefined; tocloft bailing out. All (or most) links in table of contents do not work. MWE: \DocumentMetadata{lang=en, pdfversion=2.0} \documentclass{article} \usepackage[english]{babel} \usepackage{tocloft} \usepackage[hypertexnames=false]{hyperref} \begin{document} \tableofcontents \section{123123} \subsection{absc} No links in table of contents. Comment out \verb|\DocumentMetadata| or \verb|tocloft| package and links work. \end{document} Could I do something differently? I saw Non-hyperlinked TOC entry when loading tocloft+hyperref with phase-III tagging with lualatex/xelatex 2023 #74 on latex3 / tagging-project. That is from May 2024 about XeLaTeX and LuaLaTex; pdflatex at the time seems not to have had this issue.

I am currently refining the flowchart in this problem Why does \begin{figure}[H] disrupt line spacing?. The solution in the problem involves using nested TikZ, but I have encountered another issue that I cannot resolve: For example, connecting nodes B and C across two separate TikZ environments, but the generated result is: and I want to get: LaTeX code is as follows (not exactly a minimal working example, but relatively concise): \documentclass{ctexart} \usepackage{ctex} \usepackage{setspace} \setstretch{1.5} \usepackage{float} \usepackage{tikz} \usepackage{standalone} \usetikzlibrary{positioning} \begin{document} \begin{tikzpicture}[remember picture,foo/.style={draw,inner sep=5pt},>=stealth] \node[foo,font=\bfseries] (O) {A}; \node[foo,font=\bfseries] (A) [below=of O] {\begin{tikzpicture}[remember picture,nodes={foo,draw,minimum width=1cm}] \node (X_1) {B}; \end{tikzpicture} }; \node[foo,font=\bfseries] (B) [below=of A] {\begin{tikzpicture}[remember picture,nodes={foo,draw,minimum width=1cm}] \node (X_2) {C}; \end{tikzpicture} }; \draw[-] (X_1.south) -- (X_2.north); \end{tikzpicture} \end{document} Is there any feasible approach to address this concern?

When using sidewaysfigure the resulting float is not quite centered in the type area, there is a small horizontal (or in the figure's frame of reference vertical) offset. Why is it there and how can I avoid it? Here is an MWE showing the offset (~1 mm to the left). \documentclass{article} \usepackage{rotating} \usepackage{showframe} \newlength\outertextwidth \begin{document} \outertextwidth=\textwidth \begin{sidewaysfigure} \color{orange} \rule{\textwidth}{\outertextwidth} \end{sidewaysfigure} \end{document}

Can someone please help with coding the surface plot for $\sqrt{(x - 1)^2 + y^2} + \sqrt{(x + 1)^2 + y^2} - 4 = -|z|$ in TikZ for my article in LateX? I have been trying, but can't seem to manage it. This is what I have so far, it only plots one half of the surface on a square but not within the disk: \begin{tikzpicture} \begin{axis}[ hide axis, colormap/cool, ] \addplot3[ mesh, samples=50, domain=-2:2, ] {deg(sqrt((x - 1)^2 + y^2) + sqrt((x + 1)^2 +y^2) - 4)}; \end{axis} \end{tikzpicture}

I need help with the following. As you may see, the shading effect turns out differently, if I rotate the figure. I have no idea why, and I am unable to fix it. Also, I would like to delay - so to speak - the shading effect, as to have a larger unshaded area by the vertices. \documentclass{article} \usepackage{tikz} \usetikzlibrary{shadings} \begin{document} \begin{tikzpicture} \shadedraw[lower left =red, upper left=blue, lower right=yellow, upper right=green, rotate around={0:(0,0)}] (0,0) rectangle (4,4); \end{tikzpicture} \newline \begin{tikzpicture} \shadedraw[lower left =red, upper left=blue, lower right=yellow, upper right=green, rotate around={45:(0,-4)}] (0,6) rectangle (4,10); \end{tikzpicture} \end{document}

(The order of loading hyperref and geometry doesn't make a difference) How can this problem be solved?

I am typesetting a table in landscape mode using the pdflscape package. The table has four columns, one of which contains long mathematical expressions. I want the table to fit properly on the landscape page, while the math remaining readable (no extreme shrinking), and without using tabularx or resizebox (because they produce unreadably small text in my case). However, even when specifying column widths manually, the table still exceeds the page width. Here is my script: \documentclass[12pt,a4paper]{article} \usepackage{amsmath,amssymb,amsfonts,amsthm,enumitem} \usepackage[margin=2cm]{geometry} \usepackage{graphicx} \usepackage{setspace} \usepackage{pdflscape} \onehalfspacing \DeclareMathOperator{\Var}{Var} \DeclareMathOperator{\Cov}{Cov} \DeclareMathOperator{\sgn}{sgn} \title{text} \author{names} \date{text} \begin{document} %\maketitle \begin{landscape} \begin{table}[!htbp] \centering \caption{RNML Penalty Structure Across Spatial Econometric Models} \label{tab:rnml_penalties} \small \renewcommand{\arraystretch}{1.1} \begin{tabular}{p{5cm} p{5cm} p{12cm} p{5cm}} \hline \textbf{Model} & \textbf{Spatial Dependence Type} & \textbf{RNML Adaptive Penalty Term (Spatial Component)} & \textbf{Nesting / Relation} \\ \hline \textbf{SLX} (Spatial Lag of X) & No endogenous or error feedback & No spatial autoregressive term; RNML reduces to the standard non-spatial form: \[ \frac{k}{2}\ln(n) + \ln\Gamma\!\left(\tfrac{n}{2}\right) \] & Baseline model; special case of SDM or SDEM when $\rho=\lambda=0$. \\ \textbf{SAR} (Spatial Autoregressive Model) & Endogenous spatial lag of the dependent variable & \[ \frac{1}{2}\ln\!\left( \operatorname{tr}\!\Bigl[ (\mathbf{A}^{-1}(\hat{\rho})\mathbf{W})^2 \Bigr] + \frac{1}{\hat{\sigma}^2} \hat{\boldsymbol{\beta}}^{\top}\mathbf{X}^{\top}\mathbf{W}^{\top}\mathbf{W}\mathbf{X}\hat{\boldsymbol{\beta}} \right) \] & Special case of SAC when $\lambda=0$. \\ \textbf{SEM} (Spatial Error Model) & Spatial dependence in the error term & \[ \frac{1}{2}\ln\!\left( \operatorname{tr}\!\Bigl[ (\mathbf{B}^{-1}(\hat{\lambda})\mathbf{W})^2 \Bigr] \right) \] & Special case of SAC when $\rho=0$. \\ \textbf{SDM} (Spatial Durbin Model) & Endogenous and exogenous spatial lags & \[ \frac{1}{2}\ln\!\left( \operatorname{tr}\!\Bigl[ (\mathbf{A}^{-1}(\hat{\rho})\mathbf{W})^2 \Bigr] + \frac{1}{\hat{\sigma}^2} \begin{bmatrix} \hat{\boldsymbol{\beta}} \\[0.2em] \hat{\boldsymbol{\theta}} \end{bmatrix}^{\!\top} \mathbf{X}_{+}^{\top}\mathbf{W}^{\top}\mathbf{W}\mathbf{X}_{+} \begin{bmatrix} \hat{\boldsymbol{\beta}} \\[0.2em] \hat{\boldsymbol{\theta}} \end{bmatrix} \right) \] & Reduces to SAR when $\boldsymbol{\theta}=\mathbf{0}$. \\ \textbf{SDEM} (Spatial Durbin Error Model) & Spatial lag in regressors and error autocorrelation & \[ \frac{1}{2}\ln\!\left( \operatorname{tr}\!\Bigl[ (\mathbf{B}^{-1}(\hat{\lambda})\mathbf{W})^2 \Bigr] + \frac{1}{\hat{\sigma}^2} \hat{\boldsymbol{\theta}}^{\top}\mathbf{X}^{\top}\mathbf{W}^{\top}\mathbf{W}\mathbf{X}\hat{\boldsymbol{\theta}} \right) \] & Reduces to SEM when $\boldsymbol{\theta}=\mathbf{0}$. \\ \textbf{SAC} (Spatial Autoregressive Combined Model) & Both lag and error spatial dependence & \[ \frac{1}{2}\ln\!\det\!\!\left( \begin{bmatrix} \mathcal{I}_{\rho\rho} & \mathcal{I}_{\rho\lambda} \\ \mathcal{I}_{\lambda\rho} & \mathcal{I}_{\lambda\lambda} \end{bmatrix}_{\!\!\hat{\phi}} \right) \] & Generalizes SAR and SEM; special case of GNS when $\boldsymbol{\theta}=\mathbf{0}$. \\ \textbf{GNS} (General Nesting Spatial Model) & Full specification with endogenous, exogenous, and error dependence & \[ \frac{1}{2}\ln\!\det\!\bigl( \mathcal{I}_{\phi\phi}(\hat{\phi}) \bigr) \] where $\mathcal{I}_{\phi\phi}$ includes all cross-derivatives for $(\rho,\lambda,\boldsymbol{\theta})$ & Most general model; nests SAR, SEM, SDM, SDEM, and SAC. \\ \hline \multicolumn{4}{l}{\footnotesize \textbf{Notes:} All models include the standard regression and variance penalty $\frac{k}{2}\ln(n) + \ln\Gamma\!\bigl(\tfrac{n}{2}\bigr)$.

The matrix $\mathcal{I}_{\phi\phi}$ denotes the Fisher Information Matrix block corresponding to the spatial parameters, whose curvature determines the adaptive component of the RNML penalty.

For the past few weeks, my integrals have not been displaying in display-style math mode. I can reproduce the issue with this small minimal example. How can I fix this? \documentclass[11pt]{report} \usepackage{mathtools} \usepackage{fourier-otf} \begin{document} Test \( \int_0^1 \). Test \( \displaystyle\int_0^1 \). \end{document}

I have a tikz picture that I apply scale=0.9 to that \draws a rectangle, like this: \documentclass{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture}[scale=0.9] \draw[draw=red, fill=red, fill opacity=0.3, thick] (0.24999999999999997, 5.8) -| (0.44999999999999996, 6.2) -| cycle; \end{tikzpicture} \end{document} This results in one corner not having the correct line join: If I would remove the scale argument, the line joint would be correct, but the whole picture no longer fits on my page. I also would like to avoid having to manually multiply all coordinates with 0.9. As a workaround, I could draw a second rectangle over it, with the "missing" corner in a different location. Is there a better solution?

I am migrating some existing documents in pdflatex that essentially just use Computer Modern Sans to lualatex, which seems generally to work fine without much ado. But there is one pdflatex feature I am using to simulate bleeding (custom entry in modes.mf with \pdfpkmode) that is not part of lualatex (for obvious reasons). Instead I tried with fontspec and there especially with \addfontfeatures{FakeBold=0.5} but this seems to have no effect... Question 1: Is that maybe a known limitation? Or maybe even a bug? (Or, if nobody knows, where could/should I best ask or report this besides here?) As a workaround, I tried to set everything via fontspec, but there things are apparently more subtle than one might initially presume. Seems that I would have to use at least SizeFeatures, selecting lmsans in different sizes, but would not be clear for which size ranges exactly, plus I presume there might be other things to set in order to mirror the features of pdflatex. (lmsans otf files in the latex distribution have regular/oblique/bold/oblique for 10pt, plus regular/oblique for 8pt, 9pt, 12pt and 17pt, hence it is not immediately obvious how SizeFeatures would have to be configured already just for font sizes.) Question 2: Where could I find what is actually used? Is that maybe simply in a text file in the latex distribution? Or, alternatively, does anybody know a different way to simulate bleeding in lualatex? Below is a minimal example that shows the limitations of the workaround. The paragraphs typset in default 10pt of article are the same with FakeBold, but the one in \small breaks differently at the first line. Uncommenting the \addfontfeatures line made no difference for the first set of paragraphs. I am using TeX Live 2025 on Mac (15.7.2 Sequoia Intel), updated all packages this morning. % !TEX TS-program = lualatex \documentclass{article} \usepackage{lipsum} \usepackage{color} \usepackage{fontspec} \renewcommand{\familydefault}{\sfdefault} % This has no effect if uncommented: %\addfontfeatures{FakeBold=10} \begin{document} \normalsize\lipsum[1][1-8] \small\lipsum[1][1-8] \setsansfont[ FakeBold=5, % heavy, just to show more prominently ItalicFont=lmsans10-oblique.otf, BoldFont=lmsans10-bold.otf, BoldItalicFont=lmsans10-boldoblique.otf ]{lmsans10-regular.otf} \normalsize\lipsum[1][1-8] % This paragraph breaks differently, presumably would have to use smaller lmsans \color{red}\small\lipsum[1][1-8] \end{document} Added: Below what I am essentially doing in pdflatex. Note that the paragraphs break in the same way as in the first part above, which is what I need. % !TEX TS-program = pdflatex \documentclass{article} \usepackage{lipsum} \usepackage{color} \renewcommand{\familydefault}{\sfdefault} % this makes the text just slightly bolder \pdfpkresolution=1200 \pdfpkmode={lexmarkr} \pdfmapfile{} \begin{document} \normalsize\lipsum[1][1-8] \small\lipsum[1][1-8] \end{document} Added: Just noticed that it actually does not break the same way in latex in this example (first line of first paragraph). Strange, in all my "real" examples (English texts) where I tried it so far, was exactly the same. Not sure how often that would happen generally... Added 2025-11-16: I have given up on this for the time being, essentially because in my feeling pdflatex will still be around in the next twenty years, which would be enough in my use case (my website, while for book projects, for example, I am already using lualatex). But I can share some considerations, maybe even also for myself sometime in the future, never say never... I would probably have chosen to take the Computer Modern Fonts and bleeded them, i.e. created modified versions of them with simulated bleeding, and then used them with detailed fontspec definitions in lualatex per size and type. I tried Tobias Bora's make-font-bolder script (see also this stackexchange thread) that uses fontforge: nix --extra-experimental-features nix-command --extra-experimental-features flakes \ run github:tobiasBora/make-font-bolder -- \ --size $yourSize "$sourceFontFile" "$targetFontFile" This worked for Latin Modern Sans, at least for one size, but failed for at least one of the corresponding monospaced fonts, so I stopped then. I have not tried with Computer Modern (neither with Type 1 or TrueType), but in principle, you can artifically bleed fonts. My idea would have been to maybe make the results available with bleeding amount --size from 1 to 50 somewhere online for easy use, if the above script would have just worked... Would still not be a perfect solution, of course, because of the underlying different font technology, but it would certainly help to migrate existing documents while preserving a look almost indistinguishable from the quality with pdflatex with \pdfpkmode. Added 2025-11-20: I think now I finally understand why there is "Latin Modern" and "New Computer Modern", because "Computer Modern" is tied to TeX/METAFONT, according to Donald Knuth's 1990 article "The Future of and METAFONT". Actually, the following from the article is exactly what I need/want/desire in my use case: "Therefore I believe that it is unwise to make further "improvements" to the systems called TeX and METAFONT. Let us regard these systems as fixed points, which should give the same results 100 years from now that they produce today." Actually, I am now even considering to convert some of my projects from xelatex and lualatex to pdflatex, even though I do now use TrueType fonts there and would have to convert them (the features I use/need could for all that it appears be ported (technically and legally) in these cases). That way they would also still give the same results 100 years from now. 😀
