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 have the following code: \startTEXpage[offset=20pt,width=15cm] \setuptyping[ before={\startframedtext[width=broad,framecolor=magenta]}, after={\stopframedtext}] \starttyping Framed example environment \starttyping ... \stoptyping \stoptyping \setuptyping[ before={\startframedtext[width=broad,framecolor=cyan]}, after={\stopframedtext} ] \starttyping Framed example environment \starttyping ... \stoptyping \stoptyping \setuptyping[ before={\startframedtext[width=broad,framecolor=orange]}, after={\stopframedtext}, ] \starttyping Framed example environment \starttyping ... \stoptyping \stoptyping \stopTEXpage The difference here is the trailing symbol after after={\stopframedtext}: caseA(work!) \setuptyping[ before={\startframedtext[width=broad,framecolor=magenta]}, after={\stopframedtext}] caseB(Not work!) \setuptyping[ before={\startframedtext[width=broad,framecolor=cyan]}, after={\stopframedtext} ] caseC(work!) \setuptyping[ before={\startframedtext[width=broad,framecolor=cyan]}, after={\stopframedtext}, ] The complete code gives only A and C framedbox: I was new to ConTEXt, and is that the option's key-value settings has such restrict requirement on \setuptyping? I was preferrable with the syntax as below: \mycmd[ keyA=ValA, keyB=ValB, keyC=ValC ] It looks dangerous in the ConTeXt case above? I wonder is that we should always avoid such syntax(as case B) in ConTeXt to keep the code safer? Edited Not all the commands are NOT worked with dangerous caseB syntax, and in the following case, the dangerous caseB work... \starttext \definecolor[colorA][ r=.8, g=.2, b=.2] \framed{\colorA This is colorA text} \definecolor[colorB][ r=.5, g=.1, b=.5 ] \framed{\colorB This is colorB text} \definecolor[colorC][ r=.1, g=.1, b=.9, ] \framed{\colorC This is colorC text} \stoptext

I am using the exam class to create tests and would like to provide students with a solution area that can span multiple pages if needed. The built-in environments such as solutionbox, \fillwithlines, or \makeemptybox work well for fixed-height spaces, but they do not naturally extend across page breaks (or I failed to do so...). What I would like is: a solution environment or command, that provides a large writable area, and automatically continues onto the next page(s) if necessary (e.g., like a long answer space). Here is a minimal example: \documentclass{exam} \usepackage{hyperref, graphicx} \begin{document} \begin{questions} \question[3] In no more than one paragraph, explain why the earth is round. \begin{solutionbox}{1in} The solution \end{solutionbox} \question[10] Long question requiring more space. % Desired: a solution space that can span multiple pages \begin{solution} % large writable area for students \end{solution} \end{questions} \end{document} I tried using solution, but I am not sure how to turn it into a multi-page writable area for students (not just for typeset solutions). What is the best way (within the exam class or with additional packages) to create a solution space for students that can automatically split across multiple pages?

in my research we have lots of unstable notation, i.e., we change the meaning of symbols a lot. Therefore I created a small notation package that provides macros by semantic identifiers (see here: https://gitlab.com/FranzAtGitLab/abs-smooth-notation). I then had the idea that a symbol could link to its definition if a corresponding label is found in the document. Therefore I have \newif\ifasn@links \asn@linkstrue \DeclareOption{nolinks}{\asn@linksfalse} \DeclareOption{links}{\asn@linkstrue} \ProcessOptions\relax \newcommand{\labelprefix}{asn} \makeatletter \newcommand{\maybelink}[2]{% \ifasn@links \@ifundefined{r@#2}% {#1}% {\hypersetup{hidelinks}\hyperref[#2]{#1}}% \else #1% \fi } \makeatother A simple macro is then like this \newcommand{\switchfctdx}{\maybelink{Z}{\labelprefix-switchfctdx}. You can imagine that this comes up a lot in the package. Therefore as a next step I created this: \newcommand{\definesymbol}[2]{% \expandafter\newcommand\csname #1\endcsname{% \maybelink{\ensuremath{#2}}{\labelprefix-#1}% }% } Which reduces the above definition to \definesymbol{switchfctdx}{Z}. However this does only work for the case of simple \newcommands. I also have definitions like this \NewDocumentCommand{\switchfctd}{ m }{{\maybelink{\fixed{\switchfct}}{\labelprefix-switchfctd}}_{#1}}. Of course in these cases it is not clear what part of the macro should be the link (actually every thing that is not an argument makes sense). But what annoys me the most is that I have to repeat the macro name for the label name. I would like to extend the functionality of \definesymbol in one of these ways: Have a \marker that tells \definesymbol what part is used for the link but still use the command name as the label reference automatically. Better: If no marker was set, assume everything is marked. Or even better: Use everything that is not an argument of the \NewDocumentCommand. No marker is needed. I will probably not use the full feature set of \NewDocumentCommand so a solution that can handle any number of mandatory arguments would work for me. EDIT: An example usage of the package would be \documentclass{article} \usepackage{abs-smooth-notation} \begin{document} Define \begin{equation}\label{asn-switchfctd} \switchfctd{x} := \{ \dots \}. \end{equation} The funny thing is, you can click on or hover over the symbol \(\switchfctd{x}\) to jump to its definition. This works for all symbols in the \texttt{abs-smooth-notation} package! To enable linking for a symbol defined by \texttt{\textbackslash{}symbol}, simply create a label \texttt{asn-symbol}. Here is the same for \(\texttt{\textbackslash{}Signature}\) producing \(\Signature\) \begin{equation}\label{asn-Signature} \Signature := \operatorname{diag}(\signature). \end{equation} \end{document} The minimal package code for this example would be \ProvidesPackage{abs-smooth-notation} \newif\ifasn@links \asn@linkstrue % default: links enabled \DeclareOption{nolinks}{\asn@linksfalse} \DeclareOption{links}{\asn@linkstrue} % optional explicit enable \ProcessOptions\relax \newcommand{\labelprefix}{asn} \makeatletter \newcommand{\maybelink}[2]{% \ifasn@links \@ifundefined{r@#2}% {#1}% {\hypersetup{hidelinks}\hyperref[#2]{#1}}% \else #1% \fi } \makeatother \newcommand{\definesymbol}[2]{% \expandafter\newcommand\csname #1\endcsname{% \maybelink{\ensuremath{#2}}{\labelprefix-#1}% }% } \RequirePackage{amsmath} \RequirePackage{hyperref} \providecommand{\fixed}[1]{\mathring{#1}} \definesymbol{switchfct}{F} \NewDocumentCommand{\switchfctd}{ m }{{\maybelink{\fixed{\switchfct}}{\labelprefix-switchfctd}}_{#1}} \definesymbol{signature}{\sigma} \definesymbol{Signature}{\Sigma}

I have to use this template for my dissertation, but I have a persistent issue at the \begin{document} step. As I add text to the chapters, eventually the PDF refuses to render at all, presumably because of this endgroup issue. Where is the invisible bracket? What can I do? Edit: The template can be found here. Apologies for the image, I just don't understand the issue enough to reproduce it.

When I'm reading a PDF, it's always nice if characters are encoded as themselves—that is, if searching for "≈" finds the \approx symbols, searching for "á" finds the \'{a}s, and so on. Not only does this make searching easier, but it means I can copy-paste symbols from the document into other programs. For the most part, XeLaTeX does a fantastic job of this; every standard symbol I've tried to insert has copied properly. But sometimes I'm defining my own symbols—in particular, I've drawn several of them in Inkscape, and inserted them into my document with \includegraphics. These obviously aren't searchable or copiable, since they're graphics rather than text. The same is true for TikZ pictures and anything I've synthesized by smashing standard symbols together. Is it possible to specify a Unicode codepoint that these symbols should copy and search as? I've considered drawing the character invisibly behind my graphics and \smashing it so it doesn't interfere with the spacing, but given how fantastic the support is for all the standard symbols, I suspect XeLaTeX has its own way to make this happen. MWE: \documentclass{article} \usepackage{graphicx} % I would like \myweirdsymbol to copy as U+229A, ⊚ \newcommand{\myweirdsymbol}{\includegraphics[height=10pt]{example-image-a}} \begin{document} This is a weird symbol: \myweirdsymbol{}. This is some more text. \end{document} (Of course, example-image-a looks nothing like ⊚. But that's just a random placeholder. Hopefully anything that works for them, works for any image and codepoint I choose.)

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.

Suppose a simple document that uses only the Babel and BibLaTeX packages, and that loads a .bib file in which all bibliography entries have the langid field defined. When printing the bibliography, how can the edition field and only the month part of the date field be localized according to the language of each bibliography entry — which could be any language — while all other fields remain localized in the document's main language? To provide further context, consider a first scenario in which the document has the following preamble: \usepackage[brazilian]{babel} \usepackage{biblatex} In this case, BibLaTeX localizes all references in Brazilian Portuguese. Now, a second scenario in which the autolang=other option is passed to BibLaTeX: \usepackage[brazilian]{babel} \usepackage[autolang=other]{biblatex} This time, BibLaTeX localizes each reference according to its own entry language. However, unlike what I need, all fields end up being localized. The solution I am looking for is essentially a blend of these two scenarios: the effect of autolang=other would apply only to the fields mentioned above, while the remaining fields would still be localized in Brazilian Portuguese. To help clarify, the following MWE illustrates the first scenario using the abnt style: \documentclass{article} \usepackage[brazilian]{babel} \usepackage[style=abnt]{biblatex} % This is the style I use. % Change the formatting of ordinal numbers in Brazilian Portuguese. \DefineBibliographyExtras{brazilian}{% \protected\def\mkbibordedition#1{\stripzeros{#1}\adddot}} % Redefine the formatting of the edition field so that it varies according to % the language. \DeclareFieldFormat{edition}{% \ifinteger{#1}{\mkbibordedition{#1}~\bibstring{edition}}{#1\isdot}} \begin{filecontents}{\jobname.bib} @book{Booch-Rumbaugh-Jacobson-2005a, author = {Booch, Grady and Rumbaugh, James and Jacobson, Ivar}, title = {The unified modeling language user guide}, edition = {2}, location = {Upper Saddle River}, publisher = {Addison-Wesley}, date = {2005-05}, pagetotal = {xviii, 475}, langid = {american} } @book{Rover-Mello-2024a, author = {Rover, Ardinete and Mello, Regina Oneda}, title = {Normas da ABNT}, subtitle = {orientações para a produção científica}, edition = {2}, location = {Joaçaba}, publisher = {Unoesc}, date = {2024-04-10}, pagetotal = {244}, langid = {brazil} } \end{filecontents} \addbibresource{\jobname.bib} \nocite{*} \begin{document} \printbibliography \end{document} This MWE produces the following output: For this example, the proposed solution should print the first reference as follows: 2nd ed. instead of 2. ed.; May 2005 instead of maio 2005. The second reference should remain unchanged, since the entry language defined in the langid field matches the document's main language. I have searched for discussions and solutions related to this issue, but nothing addressed my problem precisely. I also came across the BibLaTeX multiscript project, though I have not studied it thoroughly enough to determine whether it could be of use here. Since I am using the same style as the MWE, I assumed it would not be a viable path. I hope I have not made any incorrect assumptions due to a misunderstanding on my part.

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:

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} {..

(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?

I would like to reproduce the following image using the circuitikz package: So far I was able to write the following MWE: \documentclass[border=1mm, 11pt]{standalone} \usepackage{circuitikz} \usetikzlibrary{positioning} %---------------------------------------------------------------% \begin{document} \begin{circuitikz}[ node distance = 3mm and 7mm, N/.style = {draw, minimum height=13mm, text width=#1, font=\small\linespread{0,84}\selectfont, align=center}, ] \ctikzset{inductors/coils=6, quadpoles/transformer core/inner = 1.0, quadpoles/transformer core/width = 0.5, quadpoles/transformer core/height= 0.68} \node (n1) [N=13mm] {SPE\\ PHY}; \node (n2) [transformer core, rotate=90, transform shape, right=of n1, anchor=base] {}; \node (n3) [transformer core, right=of n2.south] {}; \node (n4) [N=23mm, right=of n3] {common mode\\ termination}; %--- \draw[semithick] (n2.north east) -- (n2.north east -| n1.east) (n2.north west) -- (n2.north west -| n1.east) % (n2.south east) |- (n3.north west) (n2.south west) |- (n3.south west) % (n3.north east) -- (n3.north east -| n4.west) (n3-L2.midtap) -- (n4.west) (n3.south east) -- (n3.south west -| n4.west); %-------------------- \end{circuitikz} \end{document} which produce: As you can see, connections between transformers and connecting lines are not as on image, which I want to reproduce. Is there a (if possible simple) way to improve these connections?

I used to use overleaf for work, and my documents always looked fine, but when I moved the same code to the TeXstudio editor, no matter how I tried to change the preamble or adjust the program, my document's margins weren't respected.

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.

I have a large table with many cells of the type <appropriated value>c<Mendeleev's correction>; e.g., BeCl3cBeCl2, VCl2cVCl5,...

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've noticed that monospaced fonts have uppercase Greek letters but no lowercase Greek letters. Is there a mathematical format to resolve this issue with monospaced fonts? \documentclass{article} \begin{document} $\mathtt{\Gamma \Delta \Theta \Lambda \Xi \alpha \beta \gamma \delta}$ \end{document}

I have a figure drawn with pgfplots where I cite a reference in the legend. the issue I have is when I try to scale the whole figure, I noticed that the green hyper link for the reference is not scaled and inserted at the original place. Here is an ECM with on the one hand the figure in whole size, and on the other hand the figure scaled. \documentclass{article} \usepackage{biblatex} \usepackage{hyperref} \usepackage{pgfplots} \pgfplotsset{compat=1.5} \addbibresource{biblatex-examples.bib} \begin{document} \begin{tikzpicture} \begin{axis} \addplot[red, domain=-3e-3:3e-3, samples=51]{exp(-x^2 / (2e-3^2)) / (1e-3 * sqrt(2*pi))}; \addlegendentry{Text \cite{aksin}} \end{axis} \end{tikzpicture} % \begin{tikzpicture}[scale=0.9] \begin{axis} \addplot[red, domain=-3e-3:3e-3, samples=51]{exp(-x^2 / (2e-3^2)) / (1e-3 * sqrt(2*pi))}; \addlegendentry{Text \cite{aksin}} \end{axis} \end{tikzpicture} \printbibliography \end{document} On the linked export, we see that the second green boxed is not over the reference [1], but over the place it would have been if the figure were not scaled. Is it possible to set the correct location for this box ?

I would like to use a luadraw picture as a background image on a page. I tried overlay, but this is not working as the picture is shifted above right. Luadraw is not (yet?) on CTAN, but available on github: luadraw %!TEX TS-program = lualatex \documentclass[a4paper]{article} %\usepackage[ignoreall, margin=-0cm, marginparsep=0cm]{geometry} \usepackage{luadraw} \begin{document} \begin{luadraw}{} local g = graph:new{ margins={0,0,0,0} , size={31,31} , pictureoptions="overlay" } for j= 1, 5 do for k=1,10*j do g:Dcircle(Zp(j,k*math.pi/(5*j)),1) end end g:Show(true) \end{luadraw} % without overlay, the center of the picture (on a new page) is approximately at (20,10) (if (0,0) is the bottom left corner % with overlay, the center of the picture is out the page (at (30,50) ? maybe) \end{document} (The original picture is more complex than this one, so using a standard tikzpicture is not really an option)

I am required to break the links within \url{} to my references only after / or //, not after any other symbol that also might occur in a link. How do I implement this properly for all the links to my references at once? Have I just missed an option of the hyperref package or the \url{} command, or could an input to Forcing linebreaks in \url solve the problem? I have prepared a MWE to illustrate the problem: \documentclass{article} \usepackage[hidelinks]{hyperref} \begin{document} {\raggedright \begin{thebibliography}{} \bibitem[Reference 1]{reference1} Available at \url{https://tex.stackexchange.com/one/two-three/four_five_six} \bibitem[Reference 2]{reference2} Available at \url{https://tex.stackexchange.com/seven-eight-nine/ten_eleven/twelve} \end{thebibliography} } \end{document}

I'm currently using Automate *alert*-uncovering of lines of an align in beamer to uncover (and alert) lines of an align environment one line at a time. I'm also using An alt fill-in-the-blank with question in the middle to reveal some text on a subsequent overlay. When combining these two approaches, I want the line number to be shown on the first overlay that contains that line. Currently, it is revealed on the last overlay of that line.

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.

This example of arabic text (babel with lualatex engine) does not give the desired result, text inside \underline with kashida activated displays an incorrect result.

If one produces a bibliography containing entries in Arabic, you are bound to have to use slanted text, no matter how rare this is in Arabic. Producing it in "Amiri", by Khaled Hosny, yields a text that has titles in slanted text just fine: But producing it either in Arial or Noto leaves the slanted text out and Arial is even missing a character: as one can see in this short MWE: \documentclass{article} \begin{filecontents}[overwrite]{arabic.bib} @book{Guillemin-Pollack:Persian, author = {Guillemin, Victor and Pollack, Alan}, title = {\foreignlanguage{arabic}{ﺕﻮﭘﻮﻟﻭﮋﯾ ﺪﯿﻓﺭﺎﻨﺴﯿﻟ ﻢﻗﺪﻣﺎﺘﯾ}}, publisher = {\foreignlanguage{arabic}{ﺱﺎﺤﻟ ﺎﻧﺪﯿﺸﻫ ﺖﻫﺭﺎﻧ }}, note = {\foreignlanguage{arabic}{ﺕﺮﺠﻤﻫ: ﻢﻫﺪﻳ ﻦﺠﻔﻳ ﺥﻭﺎﻫ}}, year = {2006}, pages = {108}, } @book { promenade:ar, AUTHOR = {Ghys, Étienne}, title = {\foreignlanguage{arabic}{ﻥﺯ ﻩﺓ ﺓﺭﺎﻴﻀﻳﺎﺘﻳ}}, note = {\foreignlanguage{arabic}{ﺕﺮﺠﻣﺓ: ﺢﻣﺯﺓ ﺦﻠﻴﻓ}}, PUBLISHER = {ENS Éditions}, address = {Lyon}, YEAR = {2023}, PAGES = {318}, } @book{polya-ar, author = {Pólya, George}, title = {\foreignlanguage{arabic}{ﻚﻴﻓ ﺖﺤﻟ ﻢﺳﺎٔﻟﺓ ﺮﻳﺎﻀﻳﺓ : ﻢﻨﺣﻯ ﺝﺪﻳﺩ ﻒﻳ ﺎﻠﻃﺮﻴﻗﺓ ﺎﻟﺮﻳﺎﻀﻳﺓ }}, publisher = {\foreignlanguage{arabic}{ﺎﻠﻤﻨﻈﻣﺓ ﺎﻠﻋﺮﺒﻳﺓ ﻞﻠﺗﺮﺠﻣﺓ،}}, address = {\foreignlanguage{arabic}{ ﺐﻳﺭﻮﺗ، ﻞﺒﻧﺎﻧ}}, date = {2016}, } \end{filecontents} \usepackage{fontspec} \usepackage{csquotes} \usepackage[english, bidi=basic-r]{babel} \babelprovide[import=ar, mapdigits, language=Default]{arabic} \babelfont{rm}{Times New Roman} % Default font for LTR \babelfont[arabic]{rm}{Arial} % No italic, missing a character %\babelfont[arabic]{rm}{Noto Naskh Arabic} % No italic %\babelfont[arabic]{rm}{Amiri} % Has upright and slanted \usepackage[backend=biber, style=authoryear, autolang=other, url=false, isbn=false, language=auto]{biblatex} \addbibresource{arabic.bib} \begin{document} \nocite{*} \printbibliography \end{document} Is italics missing in two widely distributed fonts, by design, or something wrong with this LaTeX set-up? Same for the missing character in Arial? Obs: Traditional italics are rare in Arabic, and "slanted" Arabic is almost entirely a modern, Western-influenced invention. Arial and Arial Italic are distributed with Windows and MacOS. For Unix one can install it using sudo apt install ttf-mscorefonts-installer. NoTO is OpenSource and distributed by Google.
