I am modifying my bibliography style (ext-authoryear) to get this for all sources that offer urls: Author, S. (year). Title. Subtitle. Publisher. Abgerufen am TT.MM.YYYY von https://www.hf.uni-koeln.de/. After days of struggle I finally managed to put URLSEEN and URLFROM in the desired order, adding the German words "Abgerufen am (URLSEEN) von (URLFROM)" with the help of a renewbibmacro command - though I still don't understand when to use URLSEEN and URLDATE. My problem is that other entry types will get a superfluous "von" at the end of the printed bib entry. I am glad for any advice!

Is there a way in TikZ or Lua to make a short function which converts letters to their corresponding alphabetical position (and vice versa)? The only way I can think of it so string check each letter, but that sounds too computationally expensive. M(non)WE: \documentclass[tikz,border=1cm]{standalone} \newcommand{\letterpos}[1]{ \pgfmathparse{#1 == a} \ifnum\pgfmathresult=1 1 \fi \pgfmathparse{#1 == ab} \ifnum\pgfmathresult=1 2 \fi \pgfmathparse{#1 == c} \ifnum\pgfmathresult=1 3 \fi \pgfmathparse{#1 == d} \ifnum\pgfmathresult=1 4 \fi \pgfmathparse{#1 == e} \ifnum\pgfmathresult=1 5 \fi } \begin{document} \begin{tikzpicture} \foreach \letter in {a,b,...,e} { \node at (\letterpos{\letter},0) {\letter}; } \end{tikzpicture} \end{document}

The default LaTeX quotation environment starts each paragraph with an indentation. I prefer for a multi-paragraph block quote not to indent the first paragraph (as recommended by the Chicago Manual of Style, for example). It is of course possible to write \begin{quotation}\noindent every time. But I would like to redefine the environment. I tried to modify the default article.cls definition of quotation minimally, but the result somehow puts a word space at the start of the quotation. How do I avoid this space without having to manually begin every block quote with a \noindent? Example: \documentclass{article} \newenvironment{lquote}{\list{}{\listparindent 1.5em% \itemindent\listparindent \rightmargin \leftmargin \parsep 0pt plus 1pt}\item\noindent\relax}% {\endlist} \begin{document} Quotation environment with explicit noindent: \begin{quotation} \noindent He finally lit on the ground and walked around the body to see if it were really dead. Peered into its nose and mouth. Examined it well from end to end and leaped upon it and bowed, and the others danced a response. That being over, he balanced and asked: ``What killed this man?'' \end{quotation} Custom environment attempting to put noindent at the beginning \begin{lquote} He finally lit on the ground and walked around the body to see if it were really dead.

I have a three-columns paracol between two paragraphs of normal text, see code and output below. In the first attempt where I use \columnratio, the second column is shifted too much to the left and overlaps the image, and the third column is also shifted too much to the right. In the second attempt where I use \setcolumnwidth, the problem with the second column has disappeared but the problem with the third column has gotten much worse. What is the best way to adjust the sizes in this situation ? The image used is available at https://github.com/jonathandoyle58/some_icons/blob/main/bart_simpson.png (although it shouldn't matter which image is used, since the \includegraphics sets the size independently of the original image size). \documentclass{article} \usepackage{calc} \usepackage[export]{adjustbox} \usepackage{multicol} \usepackage{paracol} \usepackage{lipsum} \usepackage{xcolor} \usepackage[colorlinks = true, linkcolor = blue, urlcolor = blue, citecolor = blue, anchorcolor = blue]{hyperref} \newcommand*{\foto}{% \includegraphics[width=0.2\textwidth,height=\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}+\heightof{M}]{bart_simpson}% } \begin{document} \lipsum[2] \columnratio{0.1,0.4} \begin{paracol}{3} \foto \switchcolumn \begin{flushleft} Amet ac, Aenean Ante a, Dui a.

I’m using zref-clever, and looking for a way to explicitly retrieve the various name strings associated to a given reference type — so I can write e.g. \zcrefgetstring{theorem}{Name-pl} and get “Theorems”. Presumably the package must already include some command that does roughly this, but as far as I can find, it’s not documented in the user manual, so must be internal-only. I am searching through the code, which is excellently documented but quite long and complex — so I am also asking here, either in case someone who knows the package better can give the answer quicker than I can find it, and (even if I find it first myself) to make the answer more easily searchable in future. MWE, showing approximate desired usage; expected output is hopefully clear: \documentclass{article} \usepackage{zref-clever} \newcommand{\zcrefgetstring}[2]{UNDEFINED} \begin{document} The reference type \texttt{theorem} has name \zcrefgetstring{theorem}{name-sg}. Capitalised and in plural, it is \zcrefgetstring{theorem}{Name-pl}. \end{document} Edit: I’ve tracked down the occurrence of this in reference typesetting to the calls to \__zrefclever_opt_tl_get:cNF inside \__zrefclever_type_name_setup:, but that invocation is heavily dependent on the context where it’s called during the reference-processing stack, and I haven’t yet figured out to invoke \__zrefclever_opt_tl_get successfully in an external context.

I want a three-column paracol environment where the second and third column have equal width and this width is three times the width of the first column. The command \columnratio seems indicated for this task. Unfortunately no example at all of their use is provided in the user manual. This older question gives a good, clear answer but only for two columns. Here are my failed attempts : \documentclass{article} \usepackage{paracol} \usepackage{lipsum} \usepackage{lmodern} \begin{document} \columnratio{1,3,3} \begin{paracol}{3} \lipsum[2] \switchcolumn \lipsum[2] \switchcolumn \lipsum[2] \end{paracol} \columnratio{3,3} \begin{paracol}{3} \lipsum[2] \switchcolumn \lipsum[2] \switchcolumn \lipsum[2] \end{paracol} \end{document}

When using biblatex-publist with a reference that has several authors, all co-authors are incorrectly replaced with a single "et al." See reference [1] in the screenshot for an example. What I expect is "with <name>" (as shown correctly in reference [2]) or "with <name> et al." (as shown correctly in reference [3]). Why does this happen? Is this a bug? If I use a different base style or specify maxnames=99, the problem goes away. But I don't think this is addressing the (potential) underlying bug. Here's an MWE. \documentclass{article} % \newcommand*\publistbasestyle{ieee} \usepackage[ style=publist, plauthorhandling=omit, nameorder=given-family, % maxnames=99 ]{biblatex} \plauthorname{Herrmann} \plauthorname{Kastenholz} \plauthorname{Murray} \addbibresource{biblatex-examples.bib} \begin{document} \nocite{herrmann,kastenholz,murray} \printbibliography[heading=none] \end{document}

In Springer Nature submission guidelines, they require this style in referencing: Gamelin FX, Baquet G, Berthoin S, Thevenet D, Nourry C, Nottin S, Bosquet L (2009) Effect of high intensity intermittent training on heart rate variability in prepubescent children. Eur J Appl Physiol 105:731-738. https://doi.org/10.1007/s00421-008-0955-8 at the same time, they ask for this style in citation: 'This effect has been widely studied [1-3,7].' but no matter how I try to arrange my references like this, it doesn't show an author-year style. It shows either the numeric style in citation or the author-year style. Is it possible that the journal itself edits the manuscript to show references in this style? or am I doing something wrong? this is my MWE. I don't know what to put more to help as I am new in LaTeX. \usepackage{natbib} \documentclass[pdflatex,sn-mathphys-num]{sn-jnl}% Math and Physical Sciences Numbered Reference Style \bibliographystyle{spbasic} \bibliography{sn-bibliography} By the way I used every document class I can use, but without any results.

The problem description is in the title: AMSrefs incorrectly uses singular "ed." instead of "eds." for a second bibitem with the same editors. I'm not sure if it's OK to report such bugs here, but I have done so successfully in the past, so hopefully this is OK, too. Here's a MWE (or maybe not really M, but hopefully acceptably brief): \documentclass{article} \usepackage{amsrefs} \begin{document} \begin{bibdiv} \begin{biblist} \bib{SGA-3.1}{book}{ editor={Demazure, Michel}, editor={Grothendieck, Alexander}, title={Sch\'emas en groupes. I: Propri\'et\'es g\'en\'erales des sch\'emas en groupes}, } \bib{SGA-3.2}{book}{ editor={Demazure, Michel}, editor={Grothendieck, Alexander}, title={Sch\'emas en groupes. II: Groupes de type multiplicatif, et structure des sch\'emas en groupes g\'en\'eraux}, } \end{biblist} \end{bibdiv} \end{document} The expected outcome is that the first entry is listed with "Michel Demazure and Alexander Grothendieck (eds.)", and the second entry is listed with "————— (eds.)". Actually the second entry is listed with "————— (ed.)".

I'm trying to typeset a subprotocol that spans multiple columns (because it includes multiple of the parties in the original protocol) in Cryptocode (or even have an arbitrary box span multiple columns). An example of what I'd like it to look like follows: It seems like the only thing in cryptocode that spans multiple columns is \sendmessagerightx (and equivalently left), and I can't figure out how to make other things span multiple columns. The source code for \sendmessagerightx uses \multicolumn internally, but I can't figure out a way to use it directly - that would be a nice solution if it's possible. A minimum (non-)working example is below: \documentclass{article} \usepackage{cryptocode} \begin{document} \centering \boxed{ \procedure{Protocol}{ \mathsf{Alice} \< \mathsf{Bob} \\ \dots \< \dots \\ \> \sendmessageright*{} \> \\ \dots \< \dots \\ \boxed{ \begin{subprocedure} \procedure{Subprotocol}{ \dots \< \dots \\ \> \sendmessageright*{} \\ \dots \< \dots } \end{subprocedure} } \\ } } \end{document}

I stumbled upon a weird behavior in the aligning of equations almost as long as the \linewidth. As you can see in the MWE down below all the equations are of the same length except the 'o's of the 'equation' increasing. At some point the equation 'jumps' to the left and looses its centering. I tried to google it, but didn't find an answer on whats going on with the alignment. Is there a way of keeping the centering? \documentclass[11pt,a4paper]{scrartcl} \usepackage[showframe]{geometry} \usepackage{amsmath} \begin{document} \begin{equation} looooooooooooooooooooooooooooooooooooooooooooooooooooooong\ equation \end{equation} \begin{equation} looooooooooooooooooooooooooooooooooooooooooooooooooooooong\ equatioon \end{equation} \begin{equation} looooooooooooooooooooooooooooooooooooooooooooooooooooooong\ equatiooon \end{equation} \begin{equation} looooooooooooooooooooooooooooooooooooooooooooooooooooooong\ equatioooon \end{equation} \end{document}

The code works well except with spaces. The output I get is The code does not recognize blank spaces in \tl_if_blank; instead it just goes to the false branch and prints a node with a blank space. I am sure I am missing something elementary but having looked through the documentation of interface3 I am no wiser. Any hints would be appreciated.

But even without tagging=on or no tagging option at all the hyphens are missing. The following workaround was described in the discussion, but I'm not sure if that is a good idea (and it doesn't work for me neither). \tagpdfsetup{activate/softhyphen=false} Is there something (maybe a working workaround) I can do to use IBM Plex together with \DocumentMetadata and correct hyphenation (and enable tagging) at the moment?

I am experiencing extremely weird behavior with headers in my dissertation. Sometimes, the headers are applies, and sometimes not. This changes throughout the book, without any clear indication of a pattern (at least to me). My goal is it to have the chapter on the left, and the section on the right of the heading (pretty easy stuff). I use classicthesis (with my heavy modifications to get the layout I want) that relies on KOMAscript. For the headings specifically, I use the following commands: \renewcommand{\chaptermark}[1]{\markboth{#1}{}} % I use more complex formatting, but I simplify it for the log. \renewcommand{\sectionmark}[1]{\markright{#1}} % I use more complex formatting, but I simplify it for the log. \clearpairofpagestyles \lehead{\mbox{\llap{\small\textbf{\thepage}\kern4mm}\color{black}\leftmark\hfil}} \rohead{\mbox{\hfil{\color{black}\rightmark}\rlap{\kern4mm\small\textbf{\thepage}}}} \ofoot[]{} Now, once I compile (without notable warnings / errors), I can see that the headings update sometimes, but not always. I checked my document, and I never modify the way I generate the marks (except in the ToC before section 1, and in the Bibliography in the end of the document, and both times, I wrap them in a group). I have provided some screenshots of the behavior further down the post. Can someone help me debug this issue? Do you know what might be causing this weird behavior? Or do you know a work-around to get it to work nevertheless? Some info on the document Providing a MWE is difficult, as the document grew significantly over time. I will try my best to do so right now.

I'm using LaTeX to write my resumé. I chose the geometry and multicol packages as my main tools (although I'm open to solutions using other packages), the main reason for the geometry package is to save space because I need all the document gathered on one single page. The source code below does almost what I want, with the obvious defect being located in the three-column paragraph : there is too much space (wasted space) between the photo and the text in the second column, and as a result the contact data in the third column are pushed too far to the right. Any help appreciated.

Useful texts on wavelets include Ogden (1997), Mallat (1999), and Vidakovic (1999). Most of the discussion in this chapter, however, is independent of the particular choice of basis function set, and so for most of our discussion we shall not specify the particular form of the basis functions, except for the purposes of numerical illustration. Indeed, much of our discussion will be equally applicable to the situation in which the vector $\boldsymbol{\phi}(\mathbf{x})$ of basis functions is simply the identity $\boldsymbol{\phi}(\mathbf{x}) = \mathbf{x}$. Furthermore, in order to keep the notation simple, we shall focus on the case of a single target variable $t$. However, in Section 3.1.5, we consider briefly the modifications needed to deal with multiple target variables. \subsection{Maximum likelihood and least squares} \hspace{1.6em}In Chapter 1, we fitted polynomial functions to data sets by minimizing a sum-of-squares error function. We also showed that this error function could be motivated as the maximum likelihood solution under an assumed Gaussian noise model. Let us return to this discussion and consider the least squares approach, and its relation to maximum likelihood, in more detail. As before, we assume that the target variable $t$ is given by a deterministic function $y(\mathbf{x}, \mathbf{w})$ with additive Gaussian noise so that \begin{equation} t = y(\mathbf{x}, \mathbf{w}) + \epsilon \label{eq:3.7} \end{equation} where $\epsilon$ is a zero mean Gaussian random variable with precision (inverse variance) $\beta$. Thus we can write \begin{equation} p(t|\mathbf{x}, \mathbf{w}, \beta) = \mathcal{N}(t|y(\mathbf{x}, \mathbf{w}), \beta^{-1}). \label{eq:3.8} \end{equation} Recall that, if we assume a squared loss function, then the optimal prediction, for a \marginpar{\textit{Section 1.5.5}} new value of $\mathbf{x}$, will be given by the conditional mean of the target variable. In the case of a Gaussian conditional distribution of the form (3.8), the conditional mean \end{document} I'm trying to recreate an exact page layout from a textbook in LaTeX and I'm encountering issues with the specific formatting required.

I am using the package imakeidx to make an index in my dissertation. This works as it should. I would like, however, to include a short preface between the index's heading and the actual index. How can this be done?

I’m trying to number a system of equations using the amsmath package, but I would like the equation number to appear on a specific line within the align environment. In my example, I want the numbering to appear on the second line instead of the first one. Here is the code: \documentclass{article} \usepackage{amsmath} \begin{document} \begin{align}\label{498h} \mathcal{L}\left\{ t \cos(a t) \right\} & = \frac{ s^2 - a^2 }{ (s^2 + a^2)^2 } \int_0^t \frac{\partial{K(\sigma,\gamma)}}{\partial \sigma}K_L e(\sigma) \\ & = \frac{8 h^3}{a^3}-\frac{8 (h^2-1) h}{a^3}+\frac{16 u}{a^2} \end{align} I want the numered equation on the 2nd \eqref{498h} \end{document} I would like only the second line to be numbered, leaving the first one unnumbered. Moreover, I do not want to use additional packages or the \tag command or \nonumber. In general, for example, if I have 35 line of equation, how is it possible to put, the number in the 24-th equation? I have not checked whether a similar question has already been answered on the site. Thank you all!

I just discovered that we can now create new functions (fp words) that can be evaluated inside \fp_eval:n per page 273 of interface3.pdf (it also seems to work with \fpeval). This is straightforward as the demo shows. What if I want, or need, to manipulate the function arguments to get the returned result? I can't get that to work. This functionality may not be provided yet, but I don't see it mentioned in the documentatin and searching this site turned up nothing (or I somehow missed it).

I have read the documentation of sockets and I was wondering how sockets can be used for practical use-cases. While surfing SE, I found this discussion around the topic and this mesmerizing picture-mode-illustrated answer 😛, but still didn't find a straight forward example. I asked AI to give a sample code and got the following (some manual cleanup done and some deprecated commands removed from the original AI-response): \DocumentMetadata{tagging=on} \documentclass{article} \begin{document} \NewSocket{greeting-socket}{0} \NewSocketPlug{greeting-socket}{formal}{Dear ma’am/sir,} \NewSocketPlug{greeting-socket}{informal}{Hi there,} \NewSocketPlug{greeting-socket}{friendly}{Hello, friend!} \NewSocket{closing-socket}{0} \NewSocketPlug{closing-socket}{formal}{Sincerely,} \NewSocketPlug{closing-socket}{informal}{Cheers,} \section*{Formal Letter} \AssignSocketPlug{greeting-socket}{formal} \AssignSocketPlug{closing-socket}{formal} \UseSocket{greeting-socket} This is a formal letter content. \UseSocket{closing-socket} John Doe \section*{Informal Note} \AssignSocketPlug{greeting-socket}{informal} \AssignSocketPlug{closing-socket}{informal} \UseSocket{greeting-socket} This is an informal note. \UseSocket{closing-socket} Jane \section*{Friendly Message} \AssignSocketPlug{greeting-socket}{friendly} \AssignSocketPlug{closing-socket}{informal} \UseSocket{greeting-socket} Just a quick message to say hi. \UseSocket{closing-socket} Your pal \end{document} Now the question is if this type of usage can be called "standard"? Imagine I have some code instead of the un-expandable text in the given example. Here are some questions: Are the names used here recommendable? What names do the kernel use-cases of sockets use? What should package authors use? (The documentation says: Best practice naming conventions are . . . to be documented but it is dated 2024-12-27 which is quite old now, so I assume some recommendations can be given?) Usually it is said that sockets are to be used only once unlike hooks. Does that mean multiple usages of \AssignSocketPlug wrong? The documentation does say: If the programming logic should change, then all that is necessary is to make a new assignment with \AssignSocketPlug to a different {⟨socket-plug-name⟩}. but it also says: A socket is typically only used in one place in code, but this is not a requirement, i.e., if the same operation with the same inputs need to be carried out in several places the same named socket can be used. So I am confused. In the given example, what exactly is wrong (or atypical)? The multiple uses of \AssignSocketPlug or \UseSocket? Theoretically both seem to be fine, but not sure what is expected. Is there any general consensus on what should not be used in sockets? Anything else regarding sockets based on the example or beyond it?

If I make mistakes in a Lua script and I call it from a .tex file via \directlua{ dofile("myscript.lua") } then I get a full stacktrace in the output of lualatex-compiler: myscript.lua:3: attempt to compare nil with number stack traceback: myscript.lua:3: in function 'expected_number' myscript.lua:9: in function 'fn2' myscript.lua:13: in main chunk [C]: in function 'dofile' [\directlua]:1: in main chunk. But if I call script from a console with $ texlua myscript.lua myscript.lua:3: attempt to compare nil with number I just get the last entry of the error. How can I call texlua that it prints all entries in stacktrace out? -- myscript.lua function expected_number(x) if x == 0 then return 0 end if x < 0 then return -1 end if x > 0 then return 1 end end function fn2(n) local m = expected_number(n) end local y fn2(y)

Today, I updated my TeX Live installation and noticed that a lot of packages were updated where the old and the new version number were identical. Looking into some examples, it seems like the packages are indeed unchanged. There seems to have been a modification in the CTAN catalogue that did not affect the package files at all. What is it and why did it happen? An example: One of the "updated" packages was lipsum, from version 2.7 to version 2.7. Looking at its directory page, all files date from 2021, so there was no recent change justifying an update. However, when I search for lipsum, the search result is marked as "Last modified in Catalogue: 2025-11-11 12:35". This modification must be what triggered the update. However, I could not find this date or any reference to this modification on the package page this search result entry links to (or anywhere else, for that matter).
