I want to put some test code into a macro package like this: %mypkg.sty \newif\iftest\testfalse \RequirePackage{...} some macros designed by myself \iftest\documentclass{article} preamble \begin{document} some test codes \end{document}\else\fi When \testtrue, the file mypkg.sty wish to be compiled and run, to get an output to test if the macros designed in this file work all right. If \testfalse, all the test code would be ignored, and the package mypkg.sty can be introduced by other files. It seems that this dose not work as expected. What's wrong with this method, and if there are better ways to put macros and its test code together into a .sty file?

Consider the MWE \documentclass[varwidth]{standalone} \usepackage{unicode-math} \begin{document} $aB\beta\Xi$\\$\symbf{aB\beta\Xi}$ \end{document} I don't like how \symbf switches Latin letters from italic to upright, while i only intend to make them bold, there are other commands to make a letter bold and switch font such as \symbfit and \symbfup. I would like \symbf to just make things bold. I know i can switch the font style (italic/upright) of lower/upper case Latin/Greek letters with the option math-style and the style of bold face letters by bold-style. Although, with the available options, i was only able to achieve the desired behavior with math-style=ISO,bold-style=ISO which results in everything being italic . From pre-unicode-math days, i am used to math-style=TeX and \usepackage{bm} which gives (everything italic except for upper case Greek letters, which are upright in normal and bold font). I guess the ISO/ISO configuration is fine, but i am still wondering if it is possible to reproduce this configuration in unicode-math? or even better, completely turn off the font switch of \symbf, i.e. always use the exact same italic/upright configuration for bold math as used in standard non-bold math, where "standard math" is defined by math-style)?

The Journal of Statistical Software has an extensive style guide beyond generic LaTeX conventions: dedicated preamble macros (\Plainauthor, \Address), semantic markup (\proglang, \pkg, \code), natbib citation forms, different capitalization rules for titles vs. sections vs. captions, code-formatting conventions, and completeness requirements on the .bib (e.g. doi fields). General linters like chktex and lacheck check LaTeX hygiene but know nothing about a journal's requirements, so violations tend to be found by the editors, one revision round at a time. Is there a tool that checks a .tex (or Sweave .Rnw / R Markdown .Rmd) manuscript and its bibliography against the JSS style guide specifically?

Is there a (approximately) complete list of OpenType fonts available by default within fontspec and unicode-math? I was not able to find something similar. So maybe this post could also be used to collect some. Just to specify what i mean: it is clear that there can not be a complete list as any OpenType font file (.otf) is compatible, and what font files are available by default probably varies on your TeX installation and can be looked up in /texmf/fonts/opentype. But there are some preconfigured named fonts which are loaded by name instead of loading a specific font file. As a fontspec example, loading the named font STIX Two Text and the font file STIXTwoText-Regular.otf in the following MWE \documentclass{standalone} \usepackage{fontspec} \setmainfont{STIX Two Text} \begin{document} ABC \textbf{ABC} \end{document} \documentclass{standalone} \usepackage{fontspec} \setmainfont{STIXTwoText-Regular.otf} \begin{document} ABC \textbf{ABC} \end{document} lead to and , respectively. As a unicode-math example, loading the named font NewComputerModernMath and the font file NewCMMath-Regular.otf in the following MWE \documentclass{standalone} \usepackage{unicode-math} \setmathfont{NewComputerModernMath} \begin{document} $ABC$ $\symcal{ABC}$ \end{document} \documentclass{standalone} \usepackage{unicode-math} \setmathfont{NewCMMath-Regular.otf} \begin{document} $ABC$ $\symcal{ABC}$ \end{document} lead to and , respectively. It seems to me, that these named fonts are not just equivalent to loading a specific .otf file, but there is some configuration happening in the background. (I guess they combine several .otf files.) So my question: is there a (approximatly) complete list of preconfigured named fonts provided by fontspec and unicode-math, respectively? In case fontspec and unicode-math do not provide these named fonts themselves, such a list might not exist, nevertheless they have to look them up somewhere. So, in this case, is there a way to manually look up locally available named fonts instead of playing a guess-the-name game (just like i am able to look up available .otf files in /texmf/fonts/opentype)?

I am switching to unicode-math and have some trouble with the bold fonts. I know the intended way in unicode-math is to use \symbf, \symbfcal etc. which boldens characters, but no symbols like + or accents like \tilde. This is fine when boldface is used for schematics (e.g. to denote vectors). But sometimes, i want to use mathematics just in an all-bold environment (e.g. in section titles) where just everything should be bold. I know i could set a bold version of a math alphabet and switch to that using \boldmath or \boldsymbol instead of \symbfXY. (of course setting up these fonts has to be done carefully, as one might end up with two different bold fonts otherwise.) Now, i further want to have access to two calligraphic fonts \symcal and \symscr ideally with full support for both, but i can not get that to work. Consider the following MWE (the style files are available at CTAN): \documentclass[varwidth]{standalone} \usepackage{unicode-math} \setmathfont{NewCMMath-Regular.otf} \setmathfont[version=bold]{NewCMMath-Bold.otf} \setmathfont[range={scr,bfscr}, StylisticSet=1]{NewCMMath-Regular.otf} \begin{document} $\symcal{A}$ (symcal) $\symbfcal{A}$ (symbfcal) {\boldmath$\symcal{A}$} (boldmath + symcal)\\ $\symscr{A}$ (symscr) $\symbfscr{A}$ (symbfscr) {\boldmath$\symscr{A}$} (boldmath + symscr) \end{document} producing What i want to have is I tried other configurations as well, such as: \setmathfont{NewCMMath-Regular.otf} \setmathfont[range={scr,bfscr}, StylisticSet=1]{NewCMMath-Regular.otf} \setmathfont[version=bold]{NewCMMath-Bold.otf} \setmathfont{NewCMMath-Regular.otf} \setmathfont[version=bold]{NewCMMath-Bold.otf} \setmathfont[range={scr,bfscr}, StylisticSet=1]{NewCMMath-Regular.otf} \setmathfont[version=bold, range={scr,bfscr}, StylisticSet=1]{NewCMMath-Bold.otf} I have the bad feeling that i found some hard limits of the unicode-math package. Is there any way to achieve this? I would also be happy with some workarounds if this is not possible. Maybe some adjusted .otf files. Or redefining the mechanic behind \boldmath and \boldsymbol to additionally redefine \symscr and \mathscr with \symbfscr and \mathbfscr or something (i guess these are the only non-bold alphabets, so replacing them with bold version might not be ideal, but probably good enough?) I mean, we are talking about the second calligraphic font in combination with the lesser used bold mechanic, so the use-case is probably not the most relevant. Nevertheless it feels odd to not have support for that at all, especially, as this is no problem without unicode-math using the old 8-bit engine.

As a mathematician, I use zbMATH and MathSciNet to generate bibtex database files for sources that I reference in papers that I write. Generally these bib files are almost perfect and require little editing before use, and I trust that the database editors have put great care into the algorithm that generates these files. Nonetheless, these bib files sometimes require manual editing. By far the most common issue I find myself fixing is location information appearing in the publisher field rather than the address field, which is absent entirely. For example, here are excerpts from the bib files for Wilson's textbook on finite simple groups: zbMATH: PUBLISHER = {Springer-Verlag London, Ltd.} MathSciNet: publisher = {London: Springer} Question: Is there some subtlety in using the address field that explains its absence in .bib files from zbMATH and MathSciNet? More generally, what are best practices for using this field? (For example, according to the biblatex documentation one should really call this field location instead of address.)

I have a macro who's optional argument can either follow the classic key=value syntax or a special one that gets parsed differently. To detect which one is used, I currently extract the first key (assuming key=value syntax) and feed it into \keys_if_exist:nnTF, so that if the test is false, that means I did not extract a valid key. I am however changing the way this special syntax works and it requires me to change the above method: I would now need to test if every key of the optional argument is defined, and not just the first one. My first attempt at achieving this looks like this: \ExplSyntaxOn \bool_new:N \l__intexgral_special_syntax_bool \cs_new_protected:Npn \__intexgral_eval_opt_arg:n #1 { \bool_set:Nn \l__intexgral_special_syntax_bool { \exp_args:Ne \bool_lazy_all_p:n { \keyval_parse:nnn { \keys_if_exist_p:nn { integral } } { \exp_args:Nno \keys_if_exist_p:nn { integral } \use_i:nn } { #1 } } } } \__intexgral_eval_opt_arg:n { limits=ab, variables=cartesian, } % should yield TRUE \__intexgral_eval_opt_arg:n { double, variables={x,y} } % should yield TRUE \__intexgral_eval_opt_arg:n { double S:x,y } % should yield FALSE \bool_log:N \l__intexgral_special_syntax_bool \ExplSyntaxOff But I get the following error: ! Argument of \exp_args:Nno has an extra }. <inserted text> \par l.1191 ...rg:n { limits=ab, variables=cartesian, } From what I understand, the second argument of keyval_parse:nnn should receive code after which the key and value are placed into two braced groups, thus requiring a \use_i:nn to get rid of the value. Is there a better way of determining if the optional argument follows a suitable syntax for keys_set:nn? If my method seems correct, how can I get rid of this error?

I am using amsrefs with bibliography entries written directly using biblist. For example: \documentclass{article} \usepackage[abbrev,nobysame]{amsrefs} \begin{document} See \cite{MR2365056}. \begin{bibdiv} \begin{biblist} \bib{MR2365056}{article}{ author={Balbuena, C.}, author={Cera, M.}, author={Di\'anez, A.}, author={Garc\'ia-V\'azquez, P.}, author={Marcote, X.}, title={On the edge-connectivity and restricted edge-connectivity of a product of graphs}, journal={Discrete Appl. Math.}, volume={155}, date={2007}, number={18}, pages={2444--2455}, doi={10.1016/j.dam.2007.06.014}, } \end{biblist} \end{bibdiv} \end{document} With the default amsrefs formatting, the article title is italic while the journal name is upright. I would like to reverse the default convention: the article title should be set in upright (roman) type, while the journal name should be italicized. I know that I could either write title={\textup{...} }, journal={\textit{...}}, in every bibliography entry. However, this would require modifying every bibliography entry individually, which is impractical since I have many references. All of my references are taken from MathSciNet.

I regularly use newpx for my LuaLaTeX documents with the font setup being similar to § 5, Example I of the documentation but using Asana Math as the OTF math font: \usepackage{newpxtext} \usepackage{unicode-math} \setmathfont{Asana Math} Unfortunately, I find that Asana Math's \vert is too thick at larger sizes for my taste.

In this example I splitted the areas into four sections and colored them. Is there a possibility to fill the areas without splitting them into sections? A second problem is, that the separation of each area into two parts will sometimes result in in slight white vertical line between the colored areas. In my case it depends on the scaling of the pdf viewer I use. If there area could be described without separation this should not happen.

Note: this was posted into a Github issue on zref-clever's repository, but I figured it might also be a good idea to ask about it here. Note: all code blocks here, concatenated, form a MWE. This is only broken up to ease reading. I currently have a setup to make \labels to parts of a TikZ image using a custom counter named tikzcaption, relative to the figure counter (since none of those tikzpictures will be in a subfigure environment). I want a couple things to happen when I reference those labels: if I'm in the figure environment where this tikzpicture is shown, references should be typeset as figure ("tikzcaption" in \alph, typewriter text) ; if I'm not in that figure environment, references should be typeset as figure (regular figure numbering).("tikzcaption" in \alph, typewriter text). Here's the basic setup of the counter and the reference type: \documentclass{scrbook} \KOMAoption{parskip}{half-}% % Hyperref only included to get hyperlinks working. \usepackage{tikz, zref-clever, hyperref} \makeatletter% % Create the counter for parts of a TikZ image: \newcounter{tikzcaption} \counterwithin{tikzcaption}{figure} \renewcommand*{\thetikzcaption}{\thefigure.\texttt{\arabic{tikzcaption}}} % Typeset the parts of TikZ images as the figure ones for the main document: \zcRefTypeSetup{tikzcaption}{ name-sg = {figure}, name-pl = {figures}, Name-sg = {Figure}, Name-pl = {Figures}, } % Link tikzcaption <-> figure, as zref-clever doesn't seem to detect it: \zcsetup{counterresetby = { tikzcaption = figure }}% How I (think I should) achieve the behaviour I want is by having a custom figure-like environment where I can freely change commands. Here's a rough outline of how that works: \newif\ifinreftikzpicture% Used for a couple things relative to \caption... % #1: floating env parameters \NewDocumentEnvironment{reftikzpicture}{O{htp}} { \figure[#1]% Manually start the "figure" environment. \inreftikzpicturetrue% Signal we're in the reftikzpicture env. \setcounter{tikzcaption}{0}% % Override \thetikzcaption: \let\@outside@the@tikzcaption=\thetikzcaption% \renewcommand*{\thetikzcaption}{\texttt{\alph{tikzcaption}}}% % Make the reference "names" nil within the reftikzpicture env: \zcRefTypeSetup{tikzcaption}{% name-sg = {}, name-pl = {},% Name-sg = {}, Name-pl = {},% % Ideally, should not be needed since % \thetikzcaption switches to \ttfamily reffont={\ttfamily},% }% } { % Reset the original formatting of \thetikzcaption: \renewcommand*{\thetikzcaption}{\@outside@the@tikzcaption}% \inreftikzpicturefalse% \endfigure% End the figure environment manually. } % Create the \label inside a tikzpicture: % #1: Don't print the label on the tikzpicture. % #2: Node options for the label on that picture. % #3: What node is it a legend of?

Furthermore, from the documentation it looks like the text to typeset is defined whenever the \label command is issued, and cannot be customized any further. See the document contents here: \begin{document} \begin{reftikzpicture}[ht] \centering% \begin{tikzpicture}[inner sep=0pt, outer sep=5pt]% \coordinate (circ) at (0,0);% \draw[thick, black] (circ) circle [radius=3cm];% \labeltikzat{circ}{(circ.center)}{fig/circ}% \end{tikzpicture} \caption{\zcref[S]{fig} is a \texttt{reftikzpicture}, with a single label named \zcref{fig/circ}.}% \label{fig} \end{reftikzpicture} Here are the expected and real values of the typeset references using \texttt{\string\zcref} for the different labels in the main document text: \begin{center} \begin{tabular}{p{4cm}|p{4cm}|p{4cm}} Label & Expected & Actual \\ \hline \hline \texttt{fig} & figure 1 & \zcref{fig} \\ \texttt{fig/circ} & figure 1.\texttt{a} & \zcref{fig/circ} \end{tabular} \end{center} \end{document} Gives the following document: However, I see the \zref@newlabel command records a \zc@cntval property which stores the current (local-only) value of the counter. Can I somehow use that value to print references (with hyperlinks and ranges+pairs formatting) within the reftikzpicture environment ? Using that counter to format the reference inside the reftikzpicture environment would allow for the references in the caption to be printed as they are now, but the references in the main document body would be printed as the expected values in the table.

I've seen a few examples now of Adobe Acrobat's PDF checker flagging the contents of a figure graphic based on a PDF file, when the figure in the main document has alt text and should be passing. Is there a way to force it to not check those figure file contents? TO be clear: if the graphic were saved as, say, a PNG instead of a PDF, it wouldn't be flagging the issues. I don't want people to fix their accessibility report by converting those graphics to non-PDF formats. I'm not sure if this is related to this older issue and Form Xobjects: https://github.com/latex3/tagging-project/issues/945 Here is a MWE with two figures. The first gives Character encoding failures for the line segments used in the graph (but the beta on the vertical axis causes no failures), and the second figure gives Character encoding failures for the beta on the horizontal axis. FYI, I compiled the first figure PDF using lualatex (not pdflatex as mentioned in the file below) and it still gives Character encoding errors in the main document. The second figure needs to be created in R (using R Studio) by running the commands set.seed(1); hist(rnorm(1000),40,xlab=expression(beta),main="") then exporting and saving the figure as a PDF. You may need to compile the document below then compile xobject-figure.tex to generate that PDF. Alternatively, you can download the two figure PDFs, the document PDF, and LaTeX file below with this link: http://pauljhurtado.com/latex/tmp/MWE.zip. \begin{filecontents*}[overwrite]{xobject-figure.tex} \documentclass{standalone} % Deliberately use traditional TeX math fonts. \begin{document} \setlength{\unitlength}{1cm} \begin{picture}(5,4) % axes \put(0.5,0.5){\line(1,0){4}} \put(0.5,0.5){\line(0,1){3}} % deliberately problematic math character \put(0.05,2.0){$\beta$} % a little bit of graphical content \put(0.5,0.5){\line(1,1){3}} \end{picture} \end{document} \end{filecontents*} % Generate the external PDF with pdfLaTeX. \immediate\write18{pdflatex -interaction=batchmode xobject-figure.tex} % ------------------------------------------------------------ % Main accessible document % ------------------------------------------------------------ \DocumentMetadata{ lang=en-US, tagging=on, pdfstandard=ua-2 } \documentclass{article} \usepackage[margin=0.5in]{geometry} \usepackage{graphicx} \title{Acrobat Form XObject Character-Encoding Test} \author{Test Author} \begin{document} \maketitle This document contains externally generated PDF figures, represented in the document structure by a Figure tag with alternative text.

When using \raggedright in exam.cls and the oneparchoices or oneparcheckboxes environment, the choices are listed vertically rather than on the one line. MWE attached.

I am defining custom keyboard-key commands using TikZ and the menukeys package. I defined two types of keystroke commands: one containing a normal letter and another containing a symbol such as \shift. The problem is that the \keystrokeSymbol node does not have the same height as the \keystrokeLetter node. I would like the symbol key to have exactly the same height as the letter key, while still allowing the symbol to be vertically centered. What would be the most elegant TikZ/LaTeX approach to achieve this? Note: I would prefer a solution using TikZ itself, without introducing additional packages, if possible. Code \documentclass{article} \usepackage{tikz} \usepackage{menukeys} \tikzset{ keystroke/.style={ draw=black!50, fill=yellow, %drop shadow={shadow xshift=0.15ex,shadow yshift=-0.15ex,fill=black,opacity=0.7}, rectangle, %rounded corners=0.8pt, inner xsep=0.8pt, inner ysep=0.8pt, line width=0.3pt, %minimum width=0.21cm, %minimum height=0.21cm, font=\sffamily\small, text=blue!75!black, %anchor=south } } \newcommand*\keystrokeLetter[1]{% \tikz[baseline=(key.base)] % \node[keystroke,fill=green!10](key) {#1} ;% } \newcommand*\keystrokeSymbol[1]{% \tikz[baseline=(key.base)] % \node[keystroke](key) {#1} ;% } \newcommand*\menubutton[1]{% \tikz[baseline=(key.base)] % \node[% keystroke, %signal, fill=black!8 ](key) {#1} ;% } \begin{document} first press \keystrokeLetter{A} and \keystrokeSymbol{\shift}\keystrokeLetter{R}, then click on \menubutton{FILE} \menubutton{EDIT}. \end{document} Output Desired Output

Considering the equation below, I found that when using \displaystyle, the space between the numerator in the second expression (i.e., t>t_{CP} case) and the fraction bar becomes disproportionate to the space between the numerator and the denominator in the first case. \begin{equation} P(t) = \begin{cases} \displaystyle \frac{W'}{t+\frac{W'}{P_{max}-CP}}+CP,&~~~~t\leq t_{CP}\\ \displaystyle \frac{W'}{t+\frac{W'}{P_{max}-CP}}+CP-A\cdot \ln\frac{t}{t_{CP}},&~~~~t>t_{CP} \end{cases} \end{equation} With \displaystyle: And without: A dummy fix to the version using \displaystyle is to introduce a new empty line between the two cases; nevertheless, it may not be too elegant besides making the equation take up significantly more space overall. I wonder what the best way is to avoid the expression getting crowded, and the explanation is behind this observation? I am using amsmath and amsfonts. Edit: Several nice solutions have been proposed. I would also be interested in why the spacing between the fraction bar and the symbol in the numerator changed seemingly when using \displaystyle?

I'm writing a translator from OmniGraffle (left diagram) to tikz and I've run into a bit of a problem for translating lines (right diagram). Lines in OmniGraffle are specified as a start point, middle vertices and an ending point. I can replicate the exact shape of the line from the OmniGraffle points by using tikz plot/coordinates in a draw but I'm unsure how to change the code to end at the shape boundary. Here's my MWE \documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \draw (36pt,-36pt) circle [radius=36pt ] node [] (S0) { S0}; \draw[red] plot [smooth, tension=1] coordinates { (S0) (-17.600000262260437pt, 3.89259546372341pt) (15.955999737740058pt, 28.233391483626292pt) (S0)}; \draw[red] plot [smooth, tension=1] coordinates { (36pt, -36pt) (87.40297565709261pt, 7.120001628994942pt) (57.999990582466125pt, 25.534386508502394pt) (36pt, -36pt)}; \draw[red] plot [smooth, tension=1] coordinates { (36pt, -36pt) (-15.128618137809553pt, -70.48571669739613pt) (10.699999623000622pt, -91.0802335745775pt) (36pt, -36pt)}; \end{tikzpicture} \end{document} Note, this is an early phase so things like line widths, arrowheads, text formatting, and converting out of pt coordinates are later tasks.

My code are: \documentclass[twocolumn]{article} \usepackage{array} \usepackage{tabularray} \UseTblrLibrary{booktabs} \usepackage{lipsum} \SetTblrInner{ rowsep=0pt, row{1}={l,b}, hborder{1}={belowspace=6pt}, hborder{2}={abovespace=2pt,belowspace=6pt}, hborder{Z}={abovespace=6pt}, width=\textwidth} \begin{document} \lipsum[1] \begin{table} \caption{Value of Grid Convergence Index.\label{table1-09544062261479876}} \begin{tblr}{@{\extracolsep\fill}llll@{\extracolsep\fill}} \toprule {} & {\textit{Cpmin}} & {\textit{Cpmin}} & {\textit{Cpmin}}\\ \midrule {GCI N1-N2} & {0.95\%} & {0.46\%} & {0.86\%}\\ {GCI N2-N3} & {0.59\%} & {0.33\%} & {0.58\%}\\ \bottomrule \end{tblr} \end{table} \lipsum[2-3] \begin{table*} \caption{Value of Grid Convergence Index.\label{table1-09544062261479876}} \begin{tblr}{@{\extracolsep\fill}llll@{\extracolsep\fill}} \toprule {} & {\textit{Cpmin}} & {\textit{Cpmin}} & {\textit{Cpmin}}\\ \midrule {GCI N1-N2} & {0.95\%} & {0.46\%} & {0.86\%}\\ {GCI N2-N3} & {0.59\%} & {0.33\%} & {0.58\%}\\ \bottomrule \end{tblr} \end{table*} \lipsum[1-5] \end{document} This produced the output as: How can I expand table into column/full width (using table*) by auto?
