I am preparing slides for a talk, and everything looks good. However, I want the numbering of my Definitions, Theorems, and Propositions to be aligned with the sections and to be non-repeating, something like this: Section 1: Theorem 1.1 Definition 1.2 Proposition 1.3 Theorem 1.4 Section 2: Theorem 2.1 Definition 2.2 In my current version, the theorems, definitions, and propositions are numbered sequentially (1, 2, 3, …). How can I fix my current code? Here is the relevant block of my code: \documentclass[]{beamer} \usepackage{tikz} \usepackage{amsthm,amsmath} % ------------------------ % Unified block style % ------------------------ \setbeamercolor{block title}{bg=blue, fg=white} \setbeamercolor{block body}{bg=blue!20, fg=black} % ------------------------ % Custom theorem style using plain 'block' % ------------------------ \makeatletter \def\th@unified{% \normalfont \def\inserttheoremblockenv{block} % use plain block } \makeatother \theoremstyle{unified} % ------------------------ % Single counter for all numbered environments % ------------------------ \newtheorem{proposition}[theorem]{Proposition} % shares the counter % ------------------------ % Unnumbered environments % ------------------------ \newtheorem*{remark}{Remark} \newtheorem*{question}{Question} \newtheorem*{openquestion}{Open question} % ------------------------ % Beamer settings % ------------------------ \setbeamertemplate{theorems}[numbered] \mode<presentation>{\usetheme{Madrid}} \setbeamertemplate{caption}[numbered] \setbeamertemplate{bibliography item}{\insertbiblabel} % ------------------------ % Title info % ------------------------ \title[XX]{XX} \author{XX} \institute[]{XX} \date{XX} \begin{document} \end{document}

I use a template that utilizes the document class scrreprt and thus KOMA and 1.5x line spacing. Following given guidelines, paragraphs should be separated by vertical spacing and not by indentation, which is why I put the option parskip=full- in the preamble. In order to adopt the appearance of lists to the given guidelines, I included the package enumitem and set the parameters topsep, partopsep, parsep, and itemsep, accordingly. Almost everything works as intended, with one exception: The vertical spacing above and below lists appears bigger than intended and should be smaller. I have prepared an MWE that describes the desired result. How can the MWE be modified, so that the issue regarding the vertical spacing is resolved? Changing topsep=0pt to topsep=-18pt resolves this issue only for below the list and topsep=-36pt only for above the list, despite them having a symmetric effect according to both answers on \topsep, \itemsep, \partopsep, \parsep - what do they each mean (and what about the bottom)?. Thanks in advance! P.S.: The lists without KOMA also do not fit the given guidelines, yet, it should be mentioned that KOMA changes the formatting of lists (this behavior is mentioned in its documentation) on top. MWE: \documentclass[a4paper,12pt,parskip=full-]{scrreprt} \usepackage[left=3.5cm,right=3cm,top=3.5cm,bottom=2.5cm]{geometry} \pagenumbering{gobble} \usepackage[onehalfspacing]{setspace} \usepackage{enumitem} \setlist{topsep=0pt,partopsep=18pt,parsep=18pt,itemsep=-18pt}%alternatively:topsep=-18pt or topsep=-36pt \begin{document} I want to write about \begin{enumerate} \item this, and \item that, \end{enumerate} without ending the paragraph, so there should appear 1.5x line spacing (= 18pt) above, within, and below the list, but not the increased vertical spacing of a full line that is reserved for the space between the end and the beginning of two paragraphs as follows. \par Furthermore, a list usually has something to do with its preceding and/or following text and hence is put in the same paragraph like in the example above or here, where it is preceded by a colon: \begin{enumerate} \item A sentence about this, and \item one about that \end{enumerate} ends right here. However, a list could potentially also have nothing to do with its preceding and/or following text and hence they are put into seperate paragraphs -- of which one ends with this sentence -- and show the increased vertical spacing of a full line. \par \begin{enumerate} \item A sentence on these. \item A sentence on those. \end{enumerate} \par This here is about something totally different, hence the new paragraph. Last but not least, one should not forget about paragraphs within an item of a list, as they should be seperated by the increased vertical spacing of a full line: \begin{enumerate} \item The first paragraph of the first item. \par The second paragraph of the first item. \item The second item. \end{enumerate} This line concludes the MWE. \end{document}

I’m working on a LaTeX document to specify an API for my university, and I’ve encountered a couple of issues: In my table, the text in the first column overlaps or collides with the content in the second column. How can I properly format the table to prevent this and ensure correct alignment and spacing? I’m defining a custom JSON language using listings (in json-style.sty) with UTF-8 support via the literate option. Currently, I have to manually declare each accented or special character one by one. Is there a way to reuse or import an existing set of literate definitions (such as those in accents-style.sty) when defining a new language, so I don’t have to duplicate all those character mappings (something like literate += new_definitions)? Any guidance or best practices would be greatly appreciated.

I am making a horizontal tree diagram and want the lines (or part of them) to look different in different parts of the diagram. I want to use continuous and dashed lines. Below is an example of what I want to be able to do. I want the lines to be dashed near the root and continuous as they get close to the nodes. The lines can be slightly curved or not, but I specifically do not want them to meet at the root. And a MWE: \documentclass[tikz,border=2mm]{standalone} \usetikzlibrary{trees} \begin{document} \begin{tikzpicture}[ grow=right, level distance=3cm, sibling distance=1.5cm, every node/.style={thick, minimum size=8mm} ] \node {Root} child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, dashed] { node {C} } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, dashed] { node {B} child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, solid] { node {B3} } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, solid] { node {B2} } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, solid] { node {B1} } } child [edge from parent path={(\tikzparentnode.east) -- (\tikzchildnode.west)}, dashed] { node {A} }; \end{tikzpicture} \end{document}

I would like the baseline of "with nitrogen" to be aligned with the bottom edge of the square shaded gray. The bottom of the tail (descender) in the "g" is currently setting the baseline for the phrase. I tried using \makebox[0pt]. Same edit for the other node. \documentclass[10pt]{amsart} \usepackage{tikz} \begin{document} \begin{tikzpicture}[x=1cm,y=1.5cm] %The key is drawn.

I have the following tikzpicture with \pic: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture}[ orbit/.pic={ \draw[ultra thick,gray] (0,2) arc[start angle=90,delta angle=360,x radius=.85cm, y radius=2cm] node[pos=.6,circle,fill=white,minimum size=15pt] {} node[pos=.6,circle,fill=gray] {} ; }, atom/.pic={\fill[#1] circle[radius=8pt];}, nuclear/.pic={ \pic{orbit};\pic[rotate=120] {orbit};\pic[rotate=-120] {orbit}; \foreach \i in {30,150,270}{ \pic at (\i:.45) {atom=gray};} \foreach \i in {90,210,330}{ \pic at (\i:.45) {atom=cyan};} \pic {atom=gray}; } ] % \pic{orbit};\pic[rotate=120] {orbit};\pic[rotate=-120] {orbit}; % \foreach \i in {30,150,270}{ \pic at (\i:.45) {atom=gray};} % \foreach \i in {90,210,330}{ \pic at (\i:.45) {atom=cyan};} % \pic {atom=gray}; \pic {nuclear}; \end{tikzpicture} \end{document} That is what I was after!

In a tabular environment, text needs to be placed symmetrically besides a drawing: Code: \documentclass[a4paper]{article} \usepackage{graphicx} \begin{document} \begin{tabular}[t]{@{}c@{\hspace{0.5cm}} l@{}} \includegraphics[width=0.9cm]{example-image-a} & \begin{minipage}[t]{10cm} % [t] ensures top alignment line 1\\ line 2\\ \end{minipage} \end{tabular} \end{document} Output: Text is hanging below the image. How to place the image and text side by side symmetrically?

Is there some kind of biography functionality in LaTeX that mimics the bibliography functionality? I would like to build a “library” of composer names, their dates, and biographical text, and then, like the \gls{} command, have LaTeX extract and include relevant information. The article Multi attribute lists is very helpful for implementing similar functionality, but perhaps there are solutions or packages I'm not aware of?

I know that beamerarticle does not know much of overlays. Is there still a way to access slide changes that would happen in presentation mode from within article mode maybe by patching some beamer(article) definitions? Background is that I would like to add in my article (i.e. the notes to the presentation) markers on each slide change. This is easy for new frames, but I didn't find a way to also do it for new slides within a frame (\beamer@slideinframe is always 1). Edit: here is a MWE as requested: \documentclass{article} \usepackage[T1]{fontenc} \usepackage{beamerarticle} % Define slide change marker \newcommand*\fw{[PP]} % Add marker when new frame starts \AddToHook{env/frame/begin}{% \AddToHookNext{para/begin}{\llap{\fw\hspace{1em}}} } \begin{document} \begin{frame} A new frame starts \begin{itemize}[<+->] \item One \item Two \item Three \end{itemize} \end{frame} \begin{frame} Another frame starts \end{frame} \end{document} The output is: What I want is to add the [PP] marker on every slide change (not only new frame). Consider it an indicator to click forward to the next slide.

Is it possible to create everything in a single table? Are there other table packages that you would recommend? Thank you very much in advance

But it makes the indentation of the proof name be not right, while to my surprise the the indentation of the proof name resetted is right. Note that I use MacTex 2026 the latest version, and the problem comes out after I update it. Is there is any way to fix this when I still add main=chinese,provide=* before the babel package?

The spec: Any number of (arbitrary) color bands that we specify filling text Stroked outline Same positioning as normal text No extra text in the pdf stream (for copy-paste behavior you would expect) Ok and we're back to it! Previous versions have led here. None of the solutions so far have checked every box. We got as far as implementing 1-3. This is why this question is not a duplicate of the linked questions. None of the linked solutions implement 4 which is important to me. They all draw the text multiple times which unfortunately shows up in the pdf stream. I think that it is because for each \node the text is written again, This final version should have completely normal text-selection behavior, i.e, only ONE copy of the text. I have a new macro that attempts to use \accsupp to hide the extra copies of the text, but it does not work when I test it on Sumatra. I think that it does fix it for screen readers though which is why I kept it. It will however work when I try it in random other pdf readers like chrome. What I really want here is something that somehow only writes the text once, while looking exactly as this does, so that it should work in almost all pdf viewers. % !TEX TS-program = lualatex \documentclass{article} \usepackage{tikz} \usetikzlibrary{calc} \usepackage{pgfplots} \usepackage{accsupp} \usepackage{pdfrender} \newcommand{\TextShadeContour}[3]{% \begin{tikzpicture}[baseline] % Define reference node invisibly — needed for clip coordinates \node[anchor=base, inner xsep=0pt, inner ysep=.5pt, outer sep=0pt, opacity=0] (n) at (0,0) {#3}; % Scope contains all the cumulative clips from the loop \BeginAccSupp{method=plain,ActualText={}}% \begin{scope}% \foreach \c in {1,2,...,#1}{% \pgfplotscolormapaccess[1:#1]{\c}{ShadingColor}% \definecolor{colortemp}{rgb}{\pgfmathresult}% \pgfmathparse{1-(\c-1)/#1}% \clip let \p1=(n.south west), \p2=(n.north east), in% (n.south west) rectangle (\x2, \y1+\pgfmathresult*\y2-\pgfmathresult*\y1);% \node[colortemp, anchor=base, inner xsep=0pt, inner ysep=.5pt, outer sep=0pt]% {#3};% }% \end{scope}% \EndAccSupp{}% % Stroke is now outside the scope, so clipping is fully reset \node[anchor=base, inner xsep=0pt, inner ysep=.5pt, outer sep=0pt] at (0,0) {\textpdfrender{ TextRenderingMode=Stroke, LineWidth=0.5pt, StrokeColor=#2, MiterLimit=0.5, LineJoinStyle=Round }{#3}}; \end{tikzpicture}% }% \begin{document} \pgfplotsset{colormap={ShadingColor}{rgb255=(112,128,144) rgb255=(255,159,101)}}\TextShadeContour{3}{black}{13}\\ \end{document} The question is (maybe) how to use pdf literal commands to do it. My own knowledge of pdf internals is non-existent. Or it's about drawing the path of the text from within tikz vs. the actual text. Hopefully we don't have to use ghostscript or anything funky. Ideally this will just work in a way where we define the macro once and then use it. I know a pdf file can contain this. I can prove it with this typst MWE. If you run it and copy paste the whole line, it will do it just as we want (stuff and other stuff): #let multicolor_outline(content, colors) = { let grad = gradient.linear(..colors, angle:270deg) set text(stroke: 0.3pt, fill: grad.sharp(colors.len())) box(content) } #multicolor_outline([stuff], (red, orange, yellow, green, blue, purple)) and #multicolor_outline([other stuff], (purple, blue)) Previous discussion (which does not involve functional copy-pasting): Question 1 Question 2

I have a huge intarray with more than 20k entries, that is to be loaded in some specific cases, so in that specific context, it is \inputed as an external file. The external file has content similar to \intarray_const_from_clist:Nn \g_large_intarray { 15173522, 6038, 173925, 15055255, 5164, 267192, 15044248, 4368, 362979, 14990746, 4547, 460026, 14910139, 410, 557703, 14909833, (skipping more than 2k lines of code...) } The macro that loads this file may be used inside \ExplSyntaxOn/Off regime or outside. If I add \ExplSyntaxOn/\ExplSyntaxOff to the file, if it is used inside ExplSyntax regime, it turns it off after loading it. MWE: \begin{filecontents}{foo.tex} \ExplSyntaxOn % foo code with L3 commands \int_eval:n {1+3} \ExplSyntaxOff \end{filecontents} \documentclass{article} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % code loaded in a package, user doesn't control it \ExplSyntaxOn % conditional loading, skipped in this MWE % \bool_new:N \g_foo_loaded_bool % \bool_set_false:N \g_foo_loaded_bool \cs_new:Nn \meaningful_cmd: { % some relevant commands... input foo if some condition holds \int_compare:nNnT 1 > 0 { \input{foo} } } % user command that can be used inside or outside ExplSyntax regime \NewDocumentCommand{\MeaningfulCmd}{} { \meaningful_cmd: } \ExplSyntaxOff % end of package %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \begin{document} \MeaningfulCmd % User may want to use ExplSyntax and \MeaningfulCmd inside it \ExplSyntaxOn \MeaningfulCmd % ERROR ! "Missing $ inserted" % as \ExplSyntaxOff was called in foo.tex and now _ is math subscript \int_eval:n { 3 * 5 } \ExplSyntaxOff \end{document} Is there a kind of \TempExplSyntaxOn that saves what \ExplSyntaxOn changes and when one call a fictional command like \TempExplSyntaxOff, restores the scenario, so it may be used in this context? PS.: Afterwards, I came out with a workaround: define a user command like \NewDocumentCommand{\DefineMyIntarray}{ m } { \intarray_const_from_clist:Nn \g_large_intarray { #1 } } that can be used in the external life, avoiding the need to call \ExplSyntaxOn (I will use this solution). Edit: I won't use anymore this solution that passes a huge argument to a command as @jps pointed out. So this question looses it urgency, but it is still an interesting question, as one could want to “safely” input a file with arbitrary L3 code.

I only want two modifications to the pdf file that is made from the following code: First, I do not want the separation between the first row, which is really the column headers, and the second row, which is really the first row of data. Second, I would like an equally thick vertical line separating the first column from the second column. (Again, the first column is really headers for data in the subsequent columns.) \documentclass[10pt]{amsart} \usepackage[utf8]{inputenc} \usepackage{soul} \usepackage{ragged2e} \usepackage{mathtools,array} \usepackage{tabularray} \usepackage{adjustbox} \usepackage{makecell} \begin{document} \begin{center} \begin{tblr}{colspec={Q[c,m,2.9cm]Q[c,m,2.3cm]Q[c,m,3cm]Q[c,m, 3cm]}, hlines, vlines={0.8pt}, vline{1,5}={1}{-}{}, vline{1,5}={2}{-}{0.8pt},row{1}={font=\bfseries}} {Baseline concentration\\of annual precipitation} & {\% change in\\water entering\\aquifers} & {\% change in\\surface water \\used for\\irrigation} & {\% change in\\groundwater used for\\irrigation} \\ \hline[2.4pt] %\hlines={1.6pt}{solid} {Precipitation is currently\\somewhat concentrated}&4.9&0.4&0.9 \\ {Precipitation is currently\\evenly distributed}&11.0&9.0&7.9 \end{tblr} \end{center} \end{document}

I compile with xelatex. Thank you.

I’m coloring the background of some rows, i have a drawn some hlines leaving the boundary between rows 4 and 5 in column 1 without an hline. Visually, I still get a thin white gap where that missing hline would be, even though both rows cells are fully background‑colored. I tried to “fill” that gap by drawing an hline with the same color as the background, and also by using tblrtikzabove/tblrtikzbelow to paint over the gap as a possible workaround. In all of these cases, a visible artifact remains: a narrow strip that is a slightly different shade or just white than the surrounding background, so the line is still noticeable. I cannot globally change rows/rowsep or similar table‑wide settings, because I need to scope this behavior and later add specific hlines at selected positions. What I’m looking for is a way, localized to certain row boundaries, to either eliminate that white gap entirely or fill it without causing the visible shade difference, ideally without having to restructure the whole table. \documentclass{article} \usepackage{tabularray} \usepackage{graphicx} \usepackage{geometry} \geometry{margin=0in} %\usepackage{showframe} \usepackage{siunitx} \usepackage{xcolor} \usepackage{bm} \UseTblrLibrary{tikz} \UseTblrLibrary{varwidth} \begin{document} \centering \vspace*{1em} \scalebox{0.59}{ \begin{tblrtikzabove}%tikz attempt %\draw[color=blue] (h4-|v1) -- (h4-|v3); \end{tblrtikzabove} \begin{tblr}{ colspec = { Q[c,wd=3.5cm]%1 Q[c,wd=2cm]%2 Q[c,wd=2cm]%3 Q[c,wd=2cm]%4 Q[c,wd=1.5cm]%5 Q[c,wd=1.5cm]%6 Q[c,wd=2cm]%7 Q[c,wd=2cm]%8 Q[c,wd=1.7cm]%9 Q[c,wd=1.7cm]%10 Q[c,wd=1.7cm]%11 Q[c,wd=1.7cm]%12 Q[c,wd=1.7cm]%13 Q[c,wd=1.7cm]%14 },rowsep=6pt, row{1}={h,ht=2.5cm,font=\sffamily\Large},row{2}={ht=2cm,font=\sffamily\bfseries\Large,h},row{3}={ht=.7cm,font=\sffamily\bfseries\Large},row{4}={ht=.6cm,font=\sffamily\bfseries\large},row{Z}={c,m,font=\Large\sffamily,ht=.8cm}, vlines, hline{Z,Y,1}={solid},hline{1-Z}={3-Z}{solid}, row{1-Y}={fg=red,bg=blue}, %hline{4}={1-2}{blue}, } \SetCell[r=3]{c} {\textbf{Designation}} & \SetCell[r=3]{c} \textbf{Mass per metre} & \SetCell[r=2]{c} \textbf{Depth of section} & \SetCell[r=2]{c}\textbf{Width of section} & \SetCell[c=2]{c} \textbf{Thickness} & & \SetCell[r=2]{c} \textbf{Root radius} & \SetCell[r=2]{c} \textbf{Depth between fillets} & \SetCell[c=2]{c,wd=3.4cm} \textbf{Ratios for local buckling} & & \SetCell[c=2]{c,wd=4cm} \textbf{Second moment of area} & & \SetCell[c=2]{c,wd=3.4cm} \textbf{Radius of gyration} \\ & & & & \textbf{of web} & \textbf{of flange} & & & \textbf{Flange} & \textbf{Web} & \textbf{x--x} & \textbf{y--y} & \textbf{x--x} & \textbf{y--y} \\ & & $\bm{D}$ & $\bm{B}$ & $\bm{t}$ & $\bm{T}$ & $\bm{r}$ & $\bm{d}$ & $\bm{B/2T}$ & $\bm{d/t}$ & $\bm{I_{xx}}$ & $\bm{I_{yy}}$ & $\bm{r_{xx}}$ & $\bm{r_{yy}}$ \\ \textbf{Serial size} & kg/m & mm & mm & mm & mm & mm & mm & & & \si{\textbf{cm}^{\bm{4}}} & \si{\textbf{cm}^{\bm{4}}} & cm & cm \\ 356 × 171 × 45 & 45.0 & 351.4 & 171.1 & 7.0 & 9.7 & 12.7 & 306.6 & 8.82 & 43.8 & 12195 & 811 & 14.50 & 3.75 \\ \end{tblr}} \end{document} my end goal

If you are using biblatex on an entry that use another script, biblatex applies the language rules of that entry, ignoring the style and size of the keys in the bibliography as a whole. For example, if you have an entry in English and another in Chinese, it applies the Chinese font on the entire entry, and the numbers, parens of the key will use the arabic numbers of that Chinese font instead of the numbers being used in the text. Resulting on what you see above where each script will have a different key with its own numbers. I attempted to correct this by creating a sort of hybrid font that has the Chinese characters and, for example, Times Roman numerals, in LuaLaTeX. I have succeeded in changing the font by a fall-back scheme as in here: \documentclass{report} % 1.

How can I rescale the CJK scrip to something that is usual, like 0.72 in this construct, without affecting the size of the numerals, which are coming from another font?

I recently noticed that switching from Type1 Latin Modern to OpenType Latin Modern (via unicode-math) changes the placement of subscripts (and superscripts) in both inline and display math. Inline math Consider \sum_{k = 1}^{n} a_{k}. With Type1 Latin Modern (loaded via the lmodern package), the result looks like this: Notice how the subscripts sit compactly: the subscript k in the operator does not protrude far below the baseline; also notice the subscript k in the term of the sum. With OpenType Latin Modern and unicode-math, the result is as follows: Notice that the subscript k on the operator protrudes noticeably further below the baseline, and the subscript k in a_{k} also drops lower. I prefer the Type1 behavior, where the subscripts are more compact and the overall inline expression feels tighter, so that the formula wont't stick out too much. The following GIF might also be helpful to further notice the differences: the first frame is Type1 Latin Modern and the second frame is OpenType Latin Modern. Display math A similar, but opposite, issue appears in displayed sums: with unicode-math, the upper limit n of the index of summation appears noticeably closer to the \sum operator than with Type1 fonts. I am happy with this aspect of the unicode-math behavior. However, the subscript k in the term a_{k} once again drops lower with unicode-math. This may be fine in this context, since it is a formula in display mode (hence, one does not need to be concerned with how it fits with subsequent lines in a paragraph); nevertheless, for consistency with the inline case, I would also prefer to restore the Type1 behavior for subscript placement. Here is a GIF — the first frame is without unicode-math, and the second frame is with unicode-math: Minimal working example (MWE) For Type1 Latin Modern, compile with pdftex: \documentclass{article} \usepackage{lmodern} \begin{document} \(\sum_{k = 1}^{n} a_{k}\) \[ \sum_{k = 1}^{n} a_{k} \] \end{document} For OpenType Latin Modern via unicode-math, compile with luatex: \documentclass{article} \usepackage{unicode-math} % Latin Modern Math is the default font; included for clarity. \setmathfont{Latin Modern Math} \begin{document} \(\sum_{k = 1}^{n} a_{k}\) \[ \sum_{k = 1}^{n} a_{k} \] \end{document} Question Is there a way to restore subscript placement as in the Type1 Latin Modern defaults, without switching back to Type1 fonts? Also, should I do it? That is: would this break other features where one would actually want the subscript placement of unicode-math?

I'm trying to understand “lists” and made an attempt to store 2 attributes (name and dates); \documentclass{book} \ExplSyntaxOn \prop_new:N\g_personA_prop \prop_new:N\g_personB_prop \newcommand\storeperson[3]{ \prop_gput:Nnn\g_personA_prop{#1}{#2} \prop_gput:Nnn\g_personB_prop{#1}{#3} } \newcommand\person[1]{ \prop_item:Nn\g_personA_prop{#1}~(\prop_item:Nn\g_personB_prop{#1}) } \ExplSyntaxOff \storeperson{001}{Johann Sebastian Bach}{1685–1750} \storeperson{002}{Ludwig van Beethoven}{1770–1827} \begin{document} \person{001} and \person{002} \end{document} Is this the correct way? Is there a better way to store multiple attributes? Is the ~ the correct “hard space” code? I think I read that ~ is treated differently in latex3. (Credit to Ulrike Fischer, who originally made another (one-attribute) macro from which I “Frankenstein’ed” the above attempt.)

The following MWE gives 3 warnings Font shape in size <3.486> not available with lua-unicode-math, but none with unicode-math % !TEX TS-program = lualatex \documentclass{article} \usepackage{xfrac}% \sfrac for a/b fractions \usepackage{lua-unicode-math} %\usepackage{unicode-math} \begin{document} \(\sfrac{4}{5}\) \end{document} It is unclear to me if the fix should be on the xfrac side or on the lua-unicode-side. The three warnings are for OT1/cmr/m/n, OML/cmm/m/it and OMS/cmsy/m/n. Changing the separator (as in \sfrac{4}[L]{5}) does not remove the warnings.

The code used the powerful tikz-ext package from Qrrbrbirlbel: \documentclass[tikz,border=5pt]{standalone} \usetikzlibrary{ext.paths.ortho} \begin{document} \begin{tikzpicture} \node[draw,fill=cyan] (Root) {Root}; \node[draw,fill=magenta] at (-1,-1) (nodeA) {NodeA}; \node[draw,fill=magenta] at (1,-1) (nodeB) {NodeB}; \node[draw,fill=teal] at (3,-1) (nodeC) {NodeC}; \draw[-latex] (Root) |-| (nodeA); \draw[-latex] (Root) |-| (nodeB); \coordinate (aux) at (2,-.75);% I don't want the aux here, `-0.75' is not always easy to determine \draw[-latex,magenta,thick] (Root) |-| (aux) |- (nodeC); \end{tikzpicture} \end{document} which gives: The actual desired result is something like: My code's problem is that, in the actual case, that is not always easy to know exactly the coordinate of aux, says (2,-.75). I wonder whether some extension or patch to plot the FOUR segmented arrow what I want elegantly? Edited: Claim: The difficulity here is that the nodes' position are not always on grid, says (0.123,2.324) for some outer effects, and determine the aux point with absolute distance is not always accurate. Thus, I prefer a "non-absolute-coordinate" solution here, without \coordinate (aux) at (2,-.75).

I want to use a \foreach loop to define a series of commands of the form \bf\l where \l runs through the uppercase letters of the alphabet and \bf\l evaluates to \mathbf{\l}. This is so that I don't have to manually define \bfA, \bfB, etcetera at the start of all my documents. I've tried the following setup (patched together from Defining a newcommand, with variable name, inside another newcommand): \documentclass{article} \usepackage{amsmath,pgffor} \foreach \l in {A,B,C,D} { \expandafter\newcommand\csname bf\l\endcsname{ \mathbf{\l}% } } \begin{document} $\bfA$ $\bfB$ $\bfC$ $\bfD$ \end{document} It resulted in four errors, namely that the four commands are undefined. Where am I going wrong, and why does this not work?

Suppose I have a PDF containing Math or Physics exercises, but it is not editable. I would like to know if there is an online tool or web service that allows me to: Upload the PDF. Preview the pages. Write LaTeX formulas directly on top of the PDF (for example, as annotations or overlays). Basically, I am looking for a way to add formulas written in LaTeX to the original PDF without having to recreate the entire document from scratch. Are there any tools like this available? Addendum: After my question I have found PDF Annotator but it is not free.

Everything was working just fine until I decided to update all of my packages with miktex and especially the sourcesans package. The error I got is : ! Use of ??? doesn't match its definition. ??? ! LaTeX Error: Erroneous variable \l__siunitx_print_version... l.27 ...mathrm{l} \left[\unit{\ohm\per\kilo\meter} \right] \cdot x \left[\un... If you say, e.g., \def\a1{...}', then you must always put 1' after `\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it. This error happen for every siunitx command (\qty, \unit, \num) used in math mode. Outside of math mode (in text mode), it seems to be ok. Here is a MWE : \documentclass[12pt]{article} \usepackage[utf8]{inputenc}\usepackage[T1]{fontenc} \usepackage[default]{sourcesans} % Police Source Sans \usepackage{amsmath,mathtools,amssymb,amsthm,amsfonts,bm,siunitx,commath,xfrac} % Math Presets \sisetup{detect-family=true, detect-mode=true, detect-weight=true, detect-shape=true} %police pour siunitx \begin{document} $\unit{\ohm\per\kilo\meter}$ \unit{\ohm\per\kilo\meter} \qty{90}{\kilo\volt} \end{document} I reported this bug to the sourcesans package git hub (https://github.com/silkeh/latex-sourcesanspro/issues/10#issue-4128078876) and still waiting for a response. What should I do ? Should I try to manually roll back the update ? How should i do that ? Thanks for your help

Consider the following (almost?) MWE: % lualatex test.tex \DocumentMetadata{ lang = da, tagging = on } \documentclass{ltx-talk} \usepackage{fontspec} \usepackage{pstricks} \begin{document} \begin{frame}{\visible<1->{Exercise}} \begin{enumerate} \item \visible<2->{A} \visible<3->{B} \visible<4->{% \begin{center} \begin{pspicture}(8,2) \psframe(8,2) \end{pspicture} \end{center}}% \end{enumerate} \end{frame} \end{document} Do to the order of the visible<n->{} commands, I expected the PSTricks drawing to not show up before the 4th slide but it is drawn right from the beginning. Question How do I fix the above-mentioned "issue"? Thanks in advance.
