I'm using the LaTeX package forest to render "surface grammar trees" of sentences. Using the particular grammar I'm using (Eisenberg), you can get trees where the leaves are not in natural order. E. g. the sentence "Ich suche verzweifelt einen Stift" ("I search desperately a pen") would have the adverb "verzweifelt" ("desperately") attached to the rest of the sentence at the very last layer and the syntactical analysis tree would look something like this: How is this possible in forest without having to put the adverb to the end of the sentence (which wouldn't make sense). This would produce the correct tree structure but with the wrong word order. How can I specifically move the "verzweifelt" node to the third word position without changing the tree structure? \documentclass{article} \usepackage{forest} \usetikzlibrary{calc} \usepackage[T1]{fontenc} \begin{document} \begin{forest} for tree={ grow=south, parent anchor=south, child anchor=north, align=center, l sep=15pt, s sep=10pt, edge path={ \noexpand\path [draw] (!u.south) -- +(0,-5pt) -| (.north)\forestoption{edge label}; }, } [$S_2$ [S [Ich, tier=word] [suche, tier=word] [PrGr [einen, tier=word] [Stift, tier=word] ] ] [verzweifelt, tier=word] ] \end{forest} \end{document}

I want to colour the harakat (diacritics) of a text in Pashto. I use Luatex, and I want to switch this function on and off. It should look like I tried this code: \documentclass{article} \usepackage{fontspec} \usepackage{xcolor} \usepackage{luacolor} \usepackage[bidi=basic]{babel} % Setup Arabic language \babelprovide[import, main]{arabic} % THE FIX: Use Renderer=Node instead of Harfbuzz \babelfont{rm}[Renderer=Node]{Amiri} % 1.

What might be the problem, or is there an easy option in Luatex?

I am designing a square (or “squarish” actually) map protractor in TikZ. So far, I have managed to draw the degree ticks along the four sides by clipping radial lines between two closed paths using the even odd rule like I saw in this answer. The ticks are generated in a \foreach loop. To avoid drawing long ticks on top of short ones, I separated them into two loops using a conditional test. I am not sure whether this separation is actually necessary for correct SVG export/printing, but that is how I implemented it. Below is a MWE: \documentclass[tikz]{standalone} %,convert={outfile=\main.svg} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usetikzlibrary{intersections, pgfplots.fillbetween} \pgfdeclarelayer{pre main} \pgfdeclarelayer{main} \pgfsetlayers{pre main, main} \usetikzlibrary{shapes} \begin{document} %all of this is needed to easily clip between two closed paths using even odd rule \makeatletter \def\@appendnamedsoftpath#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\expandafter\expandafter\def\expandafter\expandafter\expandafter\@temppatha\expandafter\expandafter\expandafter{\expandafter\@temppatha\@temppathb}% \pgfsyssoftpath@setcurrentpath\@temppatha } \def\@appendnamedpathforactions#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\def\expandafter\@temppatha\expandafter{\csname @temppatha\expandafter\endcsname\@temppathb}% \let\tikz@actions@path\@temppatha } \tikzset{ use path for main/.code={% \tikz@addmode{% \expandafter\pgfsyssoftpath@setcurrentpath\csname tikz@intersect@path@name@#1\endcsname }% }, append path for main/.code={% \tikz@addmode{% \@appendnamedsoftpath{#1}% }% }, use path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions\expandafter\let\expandafter\tikz@actions@path\csname tikz@intersect@path@name@#1\endcsname}% }, append path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions \@appendnamedpathforactions{#1}}% }, use path/.style={% use path for main=#1, use path for actions=#1, }, append path/.style={% append path for main=#1, append path for actions=#1 } } \makeatother \begin{tikzpicture} \pgfmathsetmacro\bigside{7} \pgfmathsetmacro\smallsidedelta{0.5} %cuts \draw[rounded corners=12pt, name path=outside] (0,0) rectangle (\bigside,\bigside); \draw[dotted, rounded corners=12pt, name path=inside] (\smallsidedelta,\smallsidedelta) rectangle (\bigside-\smallsidedelta,\bigside-\smallsidedelta); %remove before cutting or printign.

When numbers get big, they don't have enough space to fit unless the labels become too small to read (actual printing size of the protractor will be something like 7x7 or 8x8cm). So they need to be shifted in such a way that they fit. 355 in the provided image is a clear example of what I mean. I can consider shifting them radially as well, but they need to stay to the outside of the dotted line, which I can make a little smaller. I really don't know where to start and didn't manage to find anything online. Thank you for your time!

The question arised from the previous link and the luadraw solution. I am using luadraw to visualize the surface z = x^2 + y^2 together with the intersection curve corresponding to the direction u = (1,0). I would like to know whether it is possible to: Label the coordinate axes $x$, $y$, and $z$, Label the point $c = (0,0)$, Indicate the direction $u = (1,0)$, And label the function $F(t) = t^2$ corresponding to the intersection curve. When I try to use Dtext3d, the document compiles but the output appears blank in Overleaf. Is there a reliable way to add these labels when using luadraw? \documentclass[border=5pt]{standalone} \usepackage[svgnames]{xcolor} \usepackage[3d]{luadraw} \usepackage{fourier-otf} \usepackage{tikz} \begin{document} \begin{luadraw}{name=paraboloid} local g = graph3d:new{ window3d = {-2,2,-2,2,0,8}, window = {-4.5,4,-3,9.5}, size = {10,10,0}, viewdir = perspective("central",30,50,20) } -- Surface local S = cartesian3d(function(x,y) return x^2+y^2 end, 2,-2,-2,2) -- Direction local c = Origin local u = M(1,0,0) local N = pt3d.prod(u, vecK) -- Intersection curve local Curve = g:Intersection3d(S, {c,N}) -- Draw surface g:Dfacet(S, {usepalette={palGasFlame,"z"}, edgecolor="gray", clip=true}) -- Draw curve g:Dedges(Curve, {hidden=true, color="Navy", width=12}) -- Axes g:Dline3d({Origin, M(2,0,0)}, {color="black", width=1, dash="dotted"}) g:Dline3d({Origin, M(0,2,0)}, {color="black", width=1, dash="dotted"}) g:Dline3d({Origin, M(0,0,6)}, {color="black", width=1, dash="dotted"}) g:Show() \end{luadraw} % ---- 2D overlay labels (safe in Overleaf) ---- \begin{tikzpicture}[overlay] \node at (3.7,4.2) {$x$}; \node at (1.1,4.8) {$y$}; \node at (2.5,7.3) {$z$}; \end{tikzpicture} \end{document}

In §331 of tex.web we have this: first:=1; ... if not init_terminal then goto final_end; first:=last+1; {|init_terminal| has set |loc| and |last|} So, before input_ln, which is called by init_terminal, we have: loc is 0, first is 1, last is 0. Let's type x<return> in response to **. Then after init_terminal we will have: loc is 1, first is 1, last is 2. And then (due to above snippet) first will be 3. This means that first line of input is permanently kept in buffer array throughout the entire TeX job. And so the length of the first line will restrict the length of line that TeX can read. In particular, one and the same file will compile cleanly if file name is relative, and will fail to compile if file name is absolute. Why first line of input is kept in buffer array?

A MWS is as follows. \documentclass{exam-zh} \makeatletter \DeclareSymbolFont{AMSa}{U}{msa}{m}{n} %\DeclareSymbolFont{AMSb}{U}{msb}{m}{n} \DeclareMathSymbol{\therefore}{\mathrel}{AMSa}{"29} \DeclareMathSymbol{\because}{\mathrel}{AMSa}{"2A} \makeatother \begin{document} $\because ABCD=\therefore ABCD$ \end{document} As you see, the sizes of \because and \therefore in exam-zh are very small although I invoke them from amssymb. How to fix this to make the sizes of them be normal when invoking them from amssymb?

\documentclass{article} \usepackage[font=small, labelfont=bf, format=hang]{caption} \usepackage{tabularray} \usepackage{tblr-extras} \UseTblrLibrary{amsmath, booktabs, caption} \begin{document} \begin{table}[h] \centering \begin{talltblr}[caption={A talltblr table.}]{colspec={cc}} \toprule a & b\\ \midrule x & y\\ \bottomrule \end{talltblr} \end{table} \end{document} Using the code above, I get the following result for my talltblr (i.e. the caption width is limited to the table width). I tried the approach from here: \documentclass{article} \usepackage[font=small, labelfont=bf, format=hang]{caption} \usepackage{tabularray} \usepackage{tblr-extras} \UseTblrLibrary{amsmath, booktabs, caption} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \DefTblrTemplate{firsthead}{caption}{% \makebox[\tablewidth]{\parbox{\columnwidth}{% \UseTblrTemplate{caption}{normal}% }}% } \SetTblrTemplate{firsthead}{caption} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \begin{document} \begin{table}[h] \centering \caption{A regular table. A regular table. A regular table. A regular table. A regular table. A regular table. A regular table. A regular table. A regular table.} \begin{tabular}{cc} \toprule a & b\\ \midrule x & y\\ \bottomrule \end{tabular} \end{table} \begin{table}[h] \centering \caption{A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table. A tblr table.} \begin{tblr} { colspec={cc} } \toprule a & b\\ \midrule x & y\\ \bottomrule \end{tblr} \end{table} \begin{table}[h] \centering \begin{talltblr} [ caption={A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table. A talltblr table.} ] { colspec={cc} } \toprule a & b\\ \midrule x & y\\ \bottomrule \end{talltblr} \end{table} \end{document} Now the caption has the right width, but it is too close to the table itself. Also, the caption font is too big and the label is not bold, which I can fix / hack if I add \SetTblrStyle{caption-tag}{font=\small\bfseries} \SetTblrStyle{caption-text}{font=\small} but I'm not sure if this is the way to go (and it does not fix the issue of the caption touching the table). I also tried to have a look at the default caption definitions myself in the source code but I just don't understand even remotely enough of LaTeX3). Edit for clarity: I don't need to be able to control table, talltblr, and tblr with \captionsetup, I am rather looking for a way to get the same consistent captions for figure, table, tblr and talltblr environments in my document. I realise this is not easy, especially since the different caption style for talltblr is apparently a feature: I don't think it is a bug. In many aspects, tabularray is different from traditional tables https://github.com/TeXackers/tabularray/issues/255#issuecomment-1142833319)

how do i get a list that has a heading (in this example, "Deep Learning Methods" as the heading), from which level-2 entries are connected with solid lines? so far i draw the connector lines with tikz like this: which looks fine except for the extra-bolded trunk of the tree due to multiple retracing of the same connector path in my current implementation. it is super-subtle, but when you zoom out of the PDF file, you can see marginal pixel strips lacking at the upper part of the tree trunk where it's thinner than the rest. the MRE is as follows: \documentclass{article} \usepackage{tikz} \usetikzlibrary{tikzmark,calc} \tikzset{ taxonomy/.style={ overlay, remember picture } } \newcommand{\subcatindent}{1.3em} \newcommand{\methodsindent}{2.3em} \begin{document} unrelated text\\ \textbf{\tikzmarknode{dl}{\underline{Deep Learning Methods}}}\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_convo}{Convolution}}\\ \hspace*{\methodsindent}AE-based\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_ae}{Autoencoders}}\\ \hspace*{\methodsindent}Method D2\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_gan}{GANs}}\\ \hspace*{\methodsindent}Method D3\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_diff}{Diffusion}}\\ \hspace*{\methodsindent}Method D3\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_att}{Attention-Driven}}\\ \hspace*{\methodsindent}Method D3\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_ens}{Ensemble}}\\ \hspace*{\methodsindent}Method D3 \begin{tikzpicture}[taxonomy] \newcommand{\srcOffsetX}{+0.3em} \newcommand{\srcOffsetY}{-1.0ex} \coordinate (dl_start) at ($(dl.south west)+(\srcOffsetX,\srcOffsetY + 0.3ex)$); \coordinate (dl_lowest) at (dl_ens.west); \coordinate (dl_trunk) at ($(dl_start |- dl_lowest)$); \draw (dl_start) -- (dl_trunk); \draw (dl_trunk) |- (dl_convo.west); \draw (dl_trunk) |- (dl_ae.west); \draw (dl_trunk) |- (dl_gan.west); \draw (dl_trunk) |- (dl_diff.west); \draw (dl_trunk) |- (dl_att.west); \draw (dl_trunk) |- (dl_ens.west); \end{tikzpicture} \end{document} is there a way to dynamically and systematically implement this so that the connectors are drawn exactly at the place where the previous one turned 90 degrees to the right? ideally, i could turn this in a custom list environment, but so far i don't see a clear way of solving the retracing problem.

I want to define my own style of Python, so I write \documentclass{article} \usepackage{listings, xcolor} \lstset { basicstyle = \ttfamily\small, frame = leftline, framerule = 1pt, } \lstdefinelanguage{python}{ morekeywords = {python, red}, keywordstyle = {\bfseries\color{red}}, rulecolor = {\color{red}}, } \begin{document} \begin{lstlisting}[language=python] python, red \end{lstlisting} \end{document}% after compiling with texlive 2025, I got: It did not work. I thought it might be the problem with the default settings of listings.sty package, i.e. lstlang1.sty. However, I can change the style of matlab language: \documentclass{article} \usepackage{listings, xcolor} \lstset { basicstyle = \ttfamily\small, frame = leftline, framerule = 1pt, } \lstdefinelanguage{python}{ morekeywords = {python, red}, keywordstyle = {\bfseries\color{red}}, rulecolor = {\color{red}}, } \lstdefinelanguage{Matlab}{ morekeywords = {Matlab, lime}, keywordstyle = {\bfseries\color{lime}}, rulecolor = {\color{red}}, } \begin{document} \begin{lstlisting}[language=python] python, red \end{lstlisting} \begin{lstlisting}[language=Matlab] Matlab, lime \end{lstlisting} \end{document}% The output is: I wonder why it happened and how I can actually change the style of "python" language. EDIT: I found that this does not work only on TexLive 2025; my version of listings is 76899, and it's cat-version is 1.11b. If I compile this file with 1.10a and TexLive 2024 on Overleaf, all things worked well. EDIT: I found that listings package is insensitive to the language name, Python, python, and PYTHon point to the same language

Foreign words or phrases inside a mostly monolingual document should usually be displayed in italic. How can this be achieved automatically using babel? I have produced the following code: \documentclass{article} \usepackage{lipsum} \usepackage[french, british, italian]{babel} % Font for the main language \babelfont{rm}{ebgaramond} % Font for foreign languages, inverting roman and italic \babelfont [french, british]{rm}{ebgaramond-Italic} \begin{document} MAIN LANGUAGE \lipsum[1] \vspace{1em} FOREIGN LANGUAGE \foreignlanguage{british}{\lipsum[1]} \end{document} However, I can see some problems in my approach: If I define new features for the font (ligatures, character variants...) I must repeat them for both the main and the foreign font; If I add new languages I must remember to add them to the list of foreign languages to which the italic must be applied. I am quite sure that the amazing babeltransform can easily make it more automatic.

Can someone suggest a method to have Roman (upright) capitals in italic texts, in the style of Aldus Manutius and of the early Renaissance books? I believe it could probably be done with the lua.otf.font.handler but I don't know where to start. Also, I think at least two aspects need to be kept in mind: Efficiency: the approach should not be too heavy, in order to be usable also for large documents with many paragraphs in italics; Kerning: it will probably be required to define new kerning pairs for many (or every) capital, and I expect this to be done manually depending on the font used in the document. As an example to test this: \documentclass{article} \usepackage{lipsum} \usepackage{ETbb} % A font in the style of Aldus Manutius \begin{document} A B C D E F G H I J K L M N O P Q R S T U V W X Y Z \vspace{1em} \textit{A B C D E F G H I J K L M N O P Q R S T U V W X Y Z} \vspace{1em} \lipsum[1] \vspace{1em} \textit{\lipsum[1]} \end{document} Every suggestion, even if not a complete answer, is very appreciated.

I'm working on a frame where I progressively show four different images using two different datasets and across two different conditions. Hence, I was thinking to use a 2×2 table to do so. However, I'm facing some issues with the leftmost part of the table I'm working on; specifically, the dataset row should be separated by a vertical line from the below: samples and genomes which also should be rotated and vertically centered in the cell. It also appears the spacing and alignment is akward between dataset and rows below as well as between thier cells content...

The following longtable always starts at the top of the text-body. I've noticed that the very first subtable in the following longtable has one less row than the other (page-height) subtables - even though the content is almost identical. In individual cases, this can be fixed by adding \hrule height0pt\vskip-22pt before the table - determined by eye. However, this generally doesn't help if the fontsize or page geometry (height) is changed. The question is: How can this be professionally fixed? That is, all subtables (except the last one) should have the same distance from the bottom of the text-body (perhaps this distance is zero), regardless of page height or font size. \documentclass[a5paper]{article} \usepackage[margin=12mm, %paperheight=150mm,% optional 1/3 showframe=true, ]{geometry} \usepackage{pgffor} \usepackage{longtable} \def\OutFilename{\jobname-tabledata.tex} \newwrite\MyFile \immediate\openout\MyFile=\OutFilename \def\Rows{140} \foreach \n in {1,...,\Rows}{%% \ifnum\n=\Rows % \immediate\write\MyFile{\n & 0.1 & 0.2 & 0.3}% \else% \immediate\write\MyFile{\n & 0.1 & 0.2 & 0.3 \\}% \fi% }%% \immediate\closeout\MyFile \begin{document} %\footnotesize% optional 2/3 %\Large% optional 3/3 \begin{longtable}{| c c c c | } %% Very first Header ======================== \hline n & p1 & p2 & p3 \\ \hline \endfirsthead %% Header for subsequent pages ================ \hline n & p1 & p2 & p3 \\ \hline \endhead% %% Footer for all pages except last ================ \hline n & q1 & q2 & q3 \\ \hline \endfoot %% Footer for the very last page ================ \hline n & q1 & q2 & q3 \\ \hline \endlastfoot \input{\OutFilename} \end{longtable} \end{document}

I would like to create "half letters" that attach to the left side of letters in a math formula. This would not only allow for the Latin AE character, but also characters like AD, OP, TB, and so on. When using regular Tikz lines, the attachment to the left side of the main letter does not appear to have the same font as the right side. For example, I will merge A and P together: \begin{tikzpicture} \draw[x=1pt,y=1pt,xshift=1.2] (5.3,3.6) node[node font=\itshape] {P}; \draw[x=1pt,y=1pt] (0.3,0) -- (6,7); \draw[x=1pt,y=1pt] (3.1,3.5) -- (6.3,3.5); \draw[x=1pt,y=1pt] (0,0.25) -- (1,0.25); \end{tikzpicture} The result (on Overleaf): The AP merged letter, possibly useful to represent pressure in physics when P is already used for power. We see, when attaching the half-A with the P, the font does not match, and the "serif" that I attached does not match the font. How do I add a serif to the end of the diagonal line on the left half of the character that makes the attachment look like a part of the character? Preferably, I'd like a custom line style to lessen the amount of commands I have to do for each half-letter or a specific command to create a serif to be in line with the math font? Or, in this case, is it easier to just create a font? (I'm doing this for all uppercase Latin and lowercase Greek letters for completeness, so that could become quite tedious). I may also have to consider variable line thickness on the left half of the letters too, as seen on the right-side P. In summary, here are the criteria I'm considering in this project: The general shape of a serif when attached to a line at any angle (strait P versus a diagonal V). The variation of width in some lines, such as the curves on B, D and P. Intersections of lines. Advantages and disadvantages of creating a custom font (.sty), creating a serif shape in Tikz, or creating a custom line style for Tikz. This helps decide what the best option is for this project. The application I'm hoping this is useful for is to allow more characters in formulas for math, physics, and other sciences whose design could hint at what the characters mean. For example, in physics, consider the notation for volume and voltage (both are represented by V). If both volume and voltage are in one calculation, what other symbols can we use to represent either one in order to avoid confusion that still show what those symbols represent? In this case, voltage can be VT, and volume can be VU. (The choice is up to the writer, this is just an example). I plan to write a paper over this topic once I get the attachments created. While this is meant for use in physics, I see this having applications in other areas of science and mathematics as well. Thus, which option would be the best for this project, and how do I get started with it? The TIKZ site is helpful, but I did not find anything that looked immediately useful specifically for creation of Serif fonts. Any help would be appreciated!

How can I calculate or approximate the intersection(s) or lack thereof of a line and an exponential curve. My goal is to avoid using an approach which first tessellates curves into line segments, and tests each line segment pair. That is O(n^2). I want something which can scale. I think Lua is appropriate for this, based on evidence in the comments. \documentclass[tikz,border=1cm]{standalone} \begin{document} \begin{tikzpicture} \draw[->] (-2,0) -- (2,0); \draw[->] (0,-2) -- (0,e^2); \draw[domain=-2:2] plot (\x,e^\x); \draw[domain=-2:2] plot (\x,\x+1.5); % two intersections \draw[domain=-2:2] plot (\x,\x+1); % one intersection \draw[domain=-2:2] plot (\x,-\x+4.5); % one intersection \draw[domain=-2:2] plot (\x,\x); % zero intersections % My goal is to use pgfmath to calculate, or if % necessary iteratively approximate, the intersections % of these lines with the exponential curve. % If it is not easy in pgfmath, then I want a Lua-based solution. \end{tikzpicture} \end{document}

How can I use the package in a proper way? (I'm quite happy I was able to identify the source for the warnings at least as the original document is rather large and I started looking into things like How to diagnose unclosed (incomplete) \iftrue or \ifnum? but somehow I didn't get me anywhere and I don't seem to know anything more than before...)

I am using a custom tcolorbox inside an enumerate environment. By default, the item number aligns with the baseline of the box (the bottom). I want the item number to be aligned with the top edge of the colored background. I have tried setting baseline=\ht\strutbox, but the number only moves up to the baseline of the first line of text, which still leaves a gap between the number and the top edge of the box. Here is my current code and the resulting output: \documentclass{article} \usepackage[most]{tcolorbox} \usepackage{enumitem} \newtcolorbox{bluebox}{ nobeforeafter, % baseline=\ht\strutbox % I tried this, but it is not perfectly aligned to the top } \begin{document} \begin{enumerate} \item \begin{bluebox} This is the first line of the box contents.\\ This is the second line. \end{bluebox} \end{enumerate} \end{document} As, the image shows, the item number (e.g., "1.") sits lower than the top of the blue background. Is there a way to force the baseline of the tcolorbox to be its physical top, or a specific offset that accounts for the font height? I have tried: baseline=\dimexpr\ht\strutbox-\tcbheight\relax baseline=\tcbheight

I've already encountered in this site complaints that in the standard font, the horizontal lines (serifs) in the image of square brackets are too short and difficult to visually distinguish. As a workaround, some suggest using overlapping "ceil" and "floor" symbols instead of square brackets. However, this results in unacceptably long serifs. I need a new command for something intermediate and very limited in use. I don't intend to use it for matrices or any other multi-line environment. Just one short text string between brackets. Unable to find a suitable ready-made solution, I decided to write such a command myself. After all, it's just one vertical bar and two horizontal serifs. This is what I got so far. \documentclass[12pt,a4paper,notitlepage]{report} \usepackage[cp1251]{inputenc} \usepackage[T1,T2A]{fontenc} \usepackage[russian]{babel} \usepackage{amsmath, amssymb} \usepackage{mathrsfs} \usepackage{enumitem} \usepackage{relsize} \usepackage{exscale} \usepackage{perpage} \usepackage{nicefrac} \usepackage[all,cmtip]{xy} \MakePerPage{footnote} \newcommand{\LBR}{ \hspace{0.2em}\rule[0.75em]{0.2em}{0.05em}% top serif \hspace{-0.2em}\rule[-0.2em]{0.2em}{0.05em}% bottom serif \hspace{-0.3em}\rule[-0.2em]{0.1em}{1.0em}% vertical bar \hspace{0.2em} } \newcommand{\RBR}{ \hspace{0.1em}\rule[0.75em]{0.2em}{0.05em}% top serif \hspace{-0.2em}\rule[-0.2em]{0.2em}{0.05em}% bottom serif \rule[-0.2em]{0.1em}{1.0em}% vertical bar \hspace{0.2em} } \newcommand{\opni}[1] {{\RBR #1 \LBR}} \newcommand{\opcli}[1]{{\RBR #1 \RBR}} \newcommand{\clopi}[1]{{\LBR #1 \LBR}} \newcommand{\clsi}[1] {{\LBR #1 \RBR}} \begin{document} \[ \begin{array}{ll} \opni{a, b} &=\ \{x\in A: a < x < b\},\\ \opcli{a, b} &=\ \{x\in A: a < x\leqslant b\},\\ \clopi{a, b} &=\ \{x\in A: a\leqslant x < b\},\\ \clsi{a, b} &=\ \{x\in A: a\leqslant x\leqslant b\},\\ \opni{{\gets},a} &=\ \{x\in A: x < a\},\\ \opcli{{\gets},a} &=\ \{x\in A: x\leqslant a\},\\ \opni{a,{\to}} &=\ \{x\in A: a < x\},\\ \clopi{a,{\to}} &=\ \{x\in A: a\leqslant x\}. \end{array} \] $\mathbb{R}^\clsi{a,b}$ \end{document} Although not very pretty, this solution is more or less satisfactory - except for two problems. First, in some random cases the vertical bar and one of serifs are too thick. Second and more important, the brackets are not scaled inside superscript, for example, in an expression like $\mathbb{R}^\clsi{a,b}$. The reason for the first problem I don't understand. The reason for the second I understand, but have no idea what to do about it. Any help is appreciated.

I want to use the characters ἄ̱ a̱ typed with "combining macron bellow" ◌̱ (U 0331), but I do not get the correct rendering. I am using EB Garamond here, and this font support both glyphs, as I can see in the font preview software Typeface: When I compile with LuaLaTeX, I get the following result: It works for latin glyphs, but not greek ones. But, when I use other font with support for this (the free avaiable Brill font) the macron get correctly put, as you can see here: Now I am really in doubt if this is a problem on the side of the font, or a problem on the side of LuaLaTeX. Or even if I am missing some option or configuration in fontspec.

The math kerns in New Computer Modern Math have been set with the SubscriptShiftDown value set as 247 (1000 units = 10 pt) originally. This causes the subscripts to be placed too low, as compared to the traditional Computer Modern fonts. In order to change that, I've modified this parameter to 1.5pt, using Khaled Hosny's code. I found the 1.5pt value in the newcomputermodern-math.lfg goodie file for NewCM Math provided by ConTeXt (see lines 79 and 80). I wish to increase the math kern values for some glyphs. I've included \symbb{R}^n to show that the newly added math kern works, but does not modify the existing one (set to -1000 which should cause collisions). Answers to other engines are also welcome.
