How can I split my document in two (using paracol I think), such that the left part of the document occupies 30% of the page, and the right part occupies 70%, and set the background color of the left part to gray ? The whole left part needs to be gray, whether there is text or not, and with no margin. There is a header on top that is not part of this two column layout, which is set using tikz. My current text, for reference : \documentclass{article} \usepackage{expkv-cs} \usepackage{fontawesome} \usepackage[T1]{fontenc} % required ? \usepackage[margin=1cm, a4paper]{geometry} % required ? \usepackage[utf8]{inputenc} % required ? \usepackage{tikz} \usepackage{paracol} \usepackage{xcolor} \usepackage{lipsum} \setlength{\parindent}{0cm} % required ? \ekvcSplit\header { textColor={}, backgroundColor={}, firstName={}, lastName={}, occupation={}, leftContent={}, rightContent={} } { \tikz[remember picture, overlay, every node/.style={text=#1}] { \node[rectangle, fill=#2, anchor=north, minimum width=\paperwidth, minimum height=3cm](header) at (current page.north){}; \node[anchor=center](name) at (header.center) {\Huge #3 \bfseries\MakeUppercase{#4}}; \node[below](occupation) at (name.south) {#5}; \node[align=left, anchor=west](leftContent) at (header.west) [xshift=0.5cm] {#6}; \node[align=left, anchor=east](rightContent) at (header.east) [xshift=-0.5cm] {#7}; } } \begin{document} \header{ textColor={white}, backgroundColor={darkgray}, firstName={Jack}, lastName={Sparrow}, occupation={Pirate}, leftContent={ \faGlobe\; English\\ \faBirthdayCake\; 1690\\ \faCar\; Licence }, rightContent={ \faEnvelope\; jack@sparrow.com\\ \faPhone\; 333 5647380\\ \faMapMarker\; On a ship } } \vspace{5cm} % how to set to header size ? \begin{paracol}{2} \lipsum[1] \switchcolumn \lipsum[1] \end{paracol} \end{document}

In the listings package, \lstset{numbers=right,stepnumber=3,numberfirstline} gives right-aligned line numbers and numbering every third line. I would like to achieve the same behavior using the piton package instead of listings, but I can’t find equivalent options in the documentation. \documentclass{article} \usepackage{piton,xcolor} \PitonOptions{line-numbers,} %\usepackage{listings} %\lstset{ % numbers=right, % stepnumber=3, % numberfirstline %} \begin{document} %\begin{lstlisting}%[firstnumber=2] \begin{Piton} print("Hello world") x = 1 + 1 print(x) x = 1 + 2 print(x) x = 2 + 2 print(x) \end{Piton} %\end{lstlisting} \end{document}

I recently learned that it's possible to set fully custom page dimensions using geometry. However as far as I can tell, you can only do rectangular document shapes. Is it possible to use the geometry package or some other method to make the document itself circular?

I know very little about the enumext package. My intention is customize block true-false where I can choose the number of columns and create a structure similar to this one. I currently use two macros \newcommand{\truefalse}{\hfill\framebox[1.25em][c]{V}\quad\framebox[1.25em][c]{F}} \newcommand{\squarecap}[1]{\fbox{\makebox[\height]{#1}}} outside the enumext package with enumitem. Here a MWE: \documentclass[a4paper,12pt]{article} \usepackage{mathtools,amssymb} \usepackage{enumext} \usepackage{enumitem} \newcommand{\truefalse}{\hfill\framebox[1.25em][c]{V}\quad\framebox[1.25em][c]{F}} \newcommand{\squarecap}[1]{\fbox{\makebox[\height]{#1}}} \begin{document} \begin{enumext}[label=\textbf{Domanda} \arabic*.,wrap-label=\textbf{#1},list-indent=0pt, save-ans=test] \item My coat is \begin{keyans*}[columns=2,label=\Alph*,wrap-label=\squarecap{#1},labelwidth=1.5em] \item blue. \item green. \item lemon. \item magenta. \end{keyans*} \end{enumext} \textbf{Vero o falso?} \begin{enumerate} \item Se $f(x)=x^2-1$ allora $f(0)=0$\truefalse; \item La funzione $y=3x-2$ passa per l'origine degli assi cartesiani \truefalse; \item $|x+2|+|x-2|=0$ non ha soluzioni\truefalse; \item $2|x-1|<0$ per ogni $x\in\mathbb{R}$, $x\neq 1$\truefalse. \end{enumerate} \end{document}

I want to precisely place a mercatormap on my page and hence use the remember picture,overlay options. But I find no way to e.g. put the top left corner of my map to the center of the page. Here is my MWE: \def\mrcpkgprefix{} \documentclass{scrartcl} \usepackage{mercatormap} \begin{document} \begin{tikzpicture}[remember picture, overlay] \node at (current page.center) {E.g. left Corner of the map here?}; \mrcdefinemap{west=9.1,east=9.45,south=48.7,north=48.95,tile size=1cm,zoom=14} \path[draw,fill=green!10] (mrcmap.south west) rectangle (mrcmap.north east); \mrcdrawnetwork \coordinate (Stuttgart) at (mrcq cs:48.775556:9.182778); \node at (Stuttgart) {Stuttgart}; \end{tikzpicture} \end{document} Any idea which option or trick can help to do what I want to achieve?

I have translated two words of a German name with two special phonetic translators and get phonetic characters that do not show correctly with LuaTeX.

I want to make a meaningless gibberish character in METAFONT that I will use in gibberish text, and does not mean anything. The character should resemble a vertical line that is thick at the top and thin at the bottom, and smoothly transitions thick to thin. The ends of the stroke should be rounded. It should be mapped to the "A" glyph slot in the font. It should be made with a single pen stroke, not faked by overlapping different strokes.

In expl one can test if a token is active or not (just using \token_if_active:) well, I wanted to test if a given token was already active before making it active with my own definition (to, perhaps, reduce the odds of a conflict with others packages). But I ran into the following problem: \documentclass{article} \ExplSyntaxOn \tl_const:Nn \c__pack_exc_tl {!} \cs_new:Npn \pack_test_activ: { \token_if_active:NTF ! {\par \c__pack_exc_tl{}~is~activ\par} {\par \c__pack_exc_tl{}~isn't~activ\par} } \begin{document} as~expected: \token_if_active:NTF ! {\par \c__pack_exc_tl{}~is~activ\par} {\par \c__pack_exc_tl{}~isn't~activ\par} \char_set_catcode_active:N ! still~ok: \cs_set:Npn ! {Hi,} \token_if_active:NTF ! {\par \c__pack_exc_tl{}~is~activ\par} {\par \c__pack_exc_tl{}~isn't~activ\par} but: \pack_test_activ: \end{document} \ExplSyntaxOff I mean, there is a way to make the test in \pack_test_activ in which I can test the current status of the toke ! (better said, at execution time, and not with its value at definition time? EDIT Of course, rescan: \documentclass{article} \ExplSyntaxOn \tl_const:Nn \c__pack_exc_tl {!} \cs_new:Npn \pack_test_activ: { \tl_set_rescan:Nnn \l__pack_tmp_tl {} {!} \exp_args:NV \token_if_active:NTF \l__pack_tmp_tl {\par \c__pack_exc_tl{}~is~activ\par} {\par \c__pack_exc_tl{}~isn't~activ\par} } \begin{document} as~expected: \token_if_active:NTF ! {\par \c__pack_exc_tl{}~is~activ\par} {\par \c__pack_exc_tl{}~isn't~activ\par} \char_set_catcode_active:N ! still~ok: \cs_set:Npn ! {Hi,} \token_if_active:NTF ! {\par \c__pack_exc_tl{}~is~activ\par} {\par \c__pack_exc_tl{}~isn't~activ\par} (now ok:) \pack_test_activ: \end{document} \ExplSyntaxOff There is another way, or this is it?

I'm typesetting my math document in Times New Roman using XeLaTeX and the fontspec package. I'm using mtpro2 as the math font, but I've noticed that certain letters, such as u, v and w, look quite different from their TNR italic counterparts (maybe because it's advertised as a Times-compatible font). Considering I'm already using the fontspec package, I tried ditching mtpro2 entirely and using other math fonts. I consulted the LaTeX Stack Exchange master list of maths fonts and tried XITS Math, TeX Gyre Termes Math and STIX Two Math. However, these fonts lack some features that I really like about mtpro2, such as round brackets (especially for matrices) and the letter z identical to the letter z in TNR. mtpro2 is here to stay. Next, I found the 'mathastext' package, which enables alphanumeric glyphs from the text font to be used in maths environments. For example, \usepackage[basic, italic]{mathastext} replaces all the alphanumeric characters in the maths font with the corresponding characters in the text font. However, this approach led me to another issue: the spacing between letters is awful, especially the subscripted ones. Since my only issue is with the letters u, v, and w, is there a way to just replace those three and use the rest of the mtpro2 glyphs? The code I'm using for my document is really bog standard: \documentclass{memoir} % Throw an error if this is not XeLaTeX. \usepackage{ifxetex} \RequireXeTeX \usepackage[lite]{mtpro2} \usepackage[no-math]{fontspec} \setmainfont{Times New Roman} \begin{document} \end{document} Any help would be appreciated.

I am working with pythonimmediate under MiKTeX (with the --naive-flush option), but I had to update, for other purposes, my entire Anaconda/Python distribution. I have thus obtained a more recent version of Python and installed, via pip, packages related to pythonimmediate. I am now facing the following error: from pythonimmediate import newcommand, renewcommand, peek_next_char, get_next_char, get_arg_str, get_verb_arg ImportError: cannot import name 'newcommand' from 'pythonimmediate' (C:\Users\damie\anaconda3\Lib\site-packages\pythonimmediate_init_.py) I don't know how to fix this problem. It seems that the "simple" module is not being imported. I have updated the pythonimmediate LaTeX package, but the problem persists. Do you have any idea what is happening?

I'm very likely overlooking the obvious, of course, and was hesitant to ask such a basic question; but would you please direct me to a command(s) that can generate a horizontal line, as in this hackish example. Previously I used \rule[0.5ex]{10pt}{0.8pt} in LaTeX; but couldn't get that to work in ConTeXt. I've been through many of the rule and bar commands in ConTeXt but cannot locate something like this. All I've managed thus far is to add a thick overstrike on top of some emdashes. If a reason why is important, I'm trying to match some old texts that use longer and thicker lines (relative to emdash) in outline headings. Thank you. \setupbar[overstrikes][color=blue,rulethickness=2pt,continue=yes,unit=pt,offset=4] \define[1]\HBar { \overstrikes{--- --- ---} } \starttext This is a hacked \HBar{} blue line, sort of centered vertically. \stoptext

For some reason, if the next page begins with a theorem and thmtools (with amsthm) is used or the theorem has a label that is given right at the beginning of the theorem the space between the footnote and the last line on this page gets smaller (and even negative) with increasing \parskip. This continues, until the \parskip gets too large, in which case the space just becomes normal. When \baselinestretch (or \setstretch) is used, the effects get so accentuated that the footnote starts to overlap the page contents. Adding 12pt option to \documentclass also seems to increase the allowance on how much \parskip can be increased, which further worsens the situation. Here is an example: \documentclass{article} \usepackage{lipsum} \usepackage{amsthm} \usepackage{setspace} % \renewcommand{\baselinestretch}{1.5} \setstretch{1.5} \setlength{\parskip}{21pt} \newtheorem{theorem}{Theorem} \begin{document} \lipsum[1] \lipsum[1]\footnote{\lipsum[1][1]} \lipsum[1][1-10] \begin{theorem}\label{thm:A} \lipsum[1][1-4] \end{theorem} \end{document} Putting the \label to the end of theorem is not a great workaround, since that, for some reason, adds extra space after the theorem if the contents of the theorem is only a display math (which is the situation in my case). See MWE: \documentclass{article} \usepackage{lipsum} \usepackage{amsthm} \usepackage{setspace} % \renewcommand{\baselinestretch}{1.5} \setstretch{1.5} \setlength{\parskip}{21pt} \newtheorem{theorem}{Theorem} \begin{document} \lipsum[1] \lipsum[1]\footnote{\lipsum[1][1]} \lipsum[1][1-10] \begin{theorem} $$TEST$$ \label{thm:A} % Move this line above the display math and the huge space below shrinks \end{theorem} \lipsum[1] \end{document} Adding a non-breaking space (~) in front of the \label fixes the issue. I can do away with this workaround, but my question is: Why is the overlap happening? How can the overlap be fixed properly (with something in the preamble)?

This question is the successor of this, which I mentioned: However, polyglossia is a little bit conflict with ctex(That maybe my another question or issues). In the first example, without polyglossia: \documentclass[fontset=fandol,openany]{ctexbook} \usepackage[paperheight=13cm]{geometry} \ctexset{ chapter/name={第,章}, section/name={第,节} } \begin{document} \tableofcontents \chapter{开始123} \section{测试456} \chapter{开始123} \section{测试456} \end{document} However, for the second case: \documentclass[fontset=fandol,openany]{ctexbook} \usepackage[paperheight=13cm]{geometry} \usepackage{polyglossia}%<- % \setmainlanguage{chinese} \ctexset{ chapter/name={第,章}, section/name={第,节} } \begin{document} % \renewcommand{\contentsname}{目录} \tableofcontents \chapter{开始123} \section{测试456} \chapter{开始123} \section{测试456} \end{document} Noted that ctex-kit is nearly the most CJK-friendly package, which consider: linespread indentfirst character kerning ... I don't want the polyglossia package, which is used for more languages support, to change the default behaviour of ctex. It could be fixed by \renewcommand{\contentsname}{目录}, but I was not sure how many ctex's config is changed by polyglossia unexpectedly, and may be I need much more than just: \renewcommand{\baselinestretch}{1.3} \renewcommand{\contentsname}{目录} \renewcommand{\figurename}{图} \renewcommand{\tablename}{表} \renewcommand{\partname}{\color{structurecolor}} \renewcommand{\thepart}{第\zhnumber{\arabic{part}}部分} \renewcommand{\listfigurename}{插图目录} \renewcommand{\listtablename}{表格目录} \renewcommand{\bibname}{参考文献} \renewcommand{\appendixname}{附录} \renewcommand{\appendixtocname}{附录} \renewcommand{\indexname}{索\hspace{2em}引} Is that possible to ease the strange conflict between polyglossia and ctex package elegantly? (BTW, babel looks good with ctex😊) Edited: Since cabohah has pointed out a quite similar case at here.

I am trying to add the pre-release version of lua-widow-control to my local TeX directory. In the local folder, I created a new folder lua-widow-control and placed the files lua-widow-control.sty, lua-widow-control.opm and lua-widow-control.lua inside. However, after running sudo texhash, I am getting: $ kpsewhich lua-widow-control.sty /usr/local/texlive/texmf-local/tex/latex/local/lua-widow-control/lua-widow-control.sty $ kpsewhich lua-widow-control.lua /usr/local/texlive/2025/texmf-dist/tex/luatex/lua-widow-control/lua-widow-control.lua $ kpsewhich lua-widow-control.opm /usr/local/texlive/texmf-local/tex/latex/local/lua-widow-control/lua-widow-control.opm Thus somehow only the .lua file is still using the installed version, not the local version. How should I change this? (Actually more importantly, is my method of installation correct? What is the correct method?) Edit: If I put the files in /usr/local/texlive/texmf-local/tex/luatex/local/lua-widow-control/, then upon running sudo texhash, I could see with kpsewhich that the paths are indeed pointing to the local versions and not the installed versions. However, if I try to compile a document, there would still be multiple incorrect index specification for tex.gettoks() errors, thus something is still wrong, since these errors won't occur if I simply put the .sty, .lua and .opm files in the same folder as the .tex document. Even if I keep both /usr/local/texlive/texmf-local/tex/latex/local/lua-widow-control/ and /usr/local/texlive/texmf-local/tex/luatex/local/lua-widow-control/, where now the paths become: $ kpsewhich lua-widow-control.sty /usr/local/texlive/texmf-local/tex/latex/local/lua-widow-control/lua-widow-control.sty $ kpsewhich lua-widow-control.lua /usr/local/texlive/texmf-local/tex/luatex/local/lua-widow-control/lua-widow-control.opm $ kpsewhich lua-widow-control.opm /usr/local/texlive/texmf-local/tex/latex/local/lua-widow-control/lua-widow-control.opm There would still be errors incorrect index specification for tex.gettoks().

I am creating a PDF in LaTeX with multiple sections, and I want to have “Previous Section” and “Next Section” links in the footer that automatically point to the previous and next sections. \documentclass[11pt]{article} \usepackage{lipsum} \usepackage{hyperref} \hypersetup{colorlinks=true} \usepackage{fancyhdr} \pagestyle{fancy} \fancyhf{} \fancyhead[R]{\textbf{Name}} \fancyfoot[C]{\thepage} \renewcommand{\headrulewidth}{0pt} \renewcommand{\footrulewidth}{0pt} \begin{document} % ---------- First Section ---------- \fancyfoot[L]{ } \fancyfoot[R]{\hyperref[sec:second]{Next Section}} \section*{First}\label{sec:first} \lipsum[1-5] \newpage % ---------- Second Section ---------- \fancyfoot[L]{\hyperref[sec:first]{Previous Section}} \fancyfoot[R]{\hyperref[sec:third]{Next Section}} \section*{Second}\label{sec:second} \lipsum[1-5] \newpage % ---------- Third Section ---------- \fancyfoot[L]{\hyperref[sec:second]{Previous Section}} \fancyfoot[R]{ } \section*{Third}\label{sec:third} \lipsum[1-5] \newpage \end{document} But this requires me to manually update the footer for every section. I would like a solution that: Automatically detects the current section on each page. Generates the previous/next section links dynamically. Works even if sections span multiple pages. Does not require manually specifying labels or updating footers for every section.

In the tufte-book class there is no extra empty line(s) before the first section title in each chapter, while there is one before subsequent section titles under the same chapter. I certainly can include extra empty lines by hand, but is there a better (more automatic) fix? There is no such problem with tufte-handout. \documentclass{tufte-book} \begin{document} \chapter{Chapter} Why isn't there some space after this for the first section title? \section{Section 1} There is space after this for the second section. \section{Section 2} \end{document}

The code is partially taken from egreg's this answer.

I want three fonts for them. So, I want to use English and Chinese, switching frequently. And use Greek fonts in whole paragraph. \bigskip English: English Saṃskṛtāvāk Chinese: {\chinesefont 英语、中文 01234 这是一个测试} Greek: {\greekfont τὸν πόλεμον τῶν Ἀθηναῖος} It works well. However, what I want in the real case, is as follows: \bigskip An paragraph of English and Chinese, which shifts frequently. 我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。我是英语 English 和中文 Chinese 混排。 {\chinesefont 我是英语} English {\chinesefont 和中文} Chinese {\chinesefont 混排。} is okay, but extremely difficult to switch... Then a paragraph of Greek letters. \textgreek{Θουκυδίδης Ἀθηναῖος ξυνέγραψε τὸν πόλεμον τῶν Πελοποννησίων καὶ Ἀθηναίων, ὡς ἐπολέμησαν πρὸς ἀλλήλους, ἀρξάμενος εὐθὺς καθισταμένου καὶ ἐλπίσας μέγαν τε ἔσεσθαι καὶ ἀξιολογώτατον τῶν προγεγενημένων, τεκμαιρόμενος ὅτι ἀκμάζοντές τε ᾖσαν ἐς αὐτὸν ἀμφότεροι παρασκευῇ τῇ πάσῃ καὶ τὸ ἄλλο Ἑλληνικὸν ὁρῶν ξυνιστάμενον πρὸς ἑκατέρους, τὸ μὲν εὐθύς, τὸ δὲ καὶ διανοούμενον.} It's hard for \texttt{polyglossia} to support an English font together another Chinese font. Is that any ideas? \end{document} I can't set Chinese and English fonts seperately, so frequently switch is quite difficult. I have also tried Fallback, but it doesn't work: \setmainfont[Fallback=FandolSong]{EB Garamond} If somebody get familiar with ctex-bundle, to set Chinese fonts and English fonts seperately, we could use: \usepackage{ctex} \setmainfont{EB Garamond} \setCJKmainfont{FandolSong} However, polyglossia is a little bit conflict with ctex(That maybe my another question or issues). So, this post, I was only after for a ployglossia(or babel) solution.

The content in some of my frames extends too far down, even when there is vertical space above that could be used. Here is an example. I would prefer for it to use the vertical space at the top before extending off the page. Is there a clean way to accomplish (at least part) this without doing a manual negative vspace? \documentclass{beamer} \useoutertheme{smoothbars} \begin{document} \section{Summation operator and the mean} \begin{frame} \begin{theorem} Is the following equality necessarily true? \[ \sum^{n}_{i=1}\left(ax_{i}+by_{i}\right)=a\sum^{n}_{i=1}x_{i}+b\sum^{n}_{i=1}y_{i} \] \end{theorem} % \begin{theorem} Yes, it is true. But what's the intuition for it? \end{theorem} \begin{itemize} \item Whenever you're stuck proving a general statement, it's often useful to try a special case. For example, what if $n$ equals 2? \begin{block}{} Then the question reduces to the following: \begin{align} \left(ax_{1}+by_{1}\right)+\left(ax_{2}+by_{2}\right) & \,\,\,=\,\,\,a(x_{1}+x_{2})+b(y_{1}+y_{2})\\ & \Longleftrightarrow\\ \left(ax_{1}+ax_{2}\right)+\left(by_{1}+by_{2}\right) & \,\,\,=\,\,\,a(x_{1}+x_{2})+b(y_{1}+y_{2}) \end{align} \end{block} \item We're summing the same numbers, just in a different order! \end{itemize} \end{frame} \end{document} Here is the result that I get: I understand there is no so much vertical space at the top, but I would still rather have the "Theorem" text start just after the mini frames, rather than content go off the page. Maybe what I'm asking for is "vfill" behavior, where it stretches or squeezes depending on the situation?

I searched for something similar, but I didn't find anything. \documentclass{report} \usepackage{amsmath} \usepackage{mathtools} \DeclareMathOperator{\diff}{d} \begin{document} \[\int x\diff x\] \end{document} I want to get "dx" and not "d x". I was looking at ways to eat spaces after the command, but nothing, I would like to avoid adding the "x" as a parameter to the \diff operator. I would like you know if there is a way.

In the following code, the \sum in \smashoperator appears too big. But if I put \textstyle\sum in \smashoperator, then it gives the error "*.tex: error: 290: Limit controls must follow a math operator. ...extstyle\sum_{\alpha\in D_{1}\cup D_{2}}}". I don't know what to do and need help. The MWE LaTeX code is as below: \documentclass[11pt,twoside]{article}% \usepackage{amssymb} \usepackage{amsmath} \usepackage{amsfonts} \usepackage{mathtools} \usepackage[title,titletoc,header]{appendix} \usepackage{geometry} \usepackage{graphicx} \usepackage{indentfirst} \usepackage{mathrsfs} \usepackage{nopageno} \usepackage{setspace} \usepackage{remreset} \newtheorem{theorem}{Theorem}[section] \newtheorem{definition}[theorem]{Definition} \begin{document} \begin{enumerate} \item $\smashoperator{\sum_{\alpha\in D_{1}\cup D_{2}}}\,x_{\alpha}\,=\underset{\alpha\in D_{1}}{\textstyle\sum}x_{\alpha} \,+\underset{\alpha\in D_{2}}{\textstyle\sum}x_{\alpha}$ \end{enumerate} \end{document}

Can somebody explain what is happening? Edit: Also in the first case autocompile doesn't work, saying that my code has errors that must be fixed first before that can run, but for the second case autocompile works.

I'm wondering if there are predefined symbols chromosomes-dna in pdfLaTeX or done in TikZ similar to those used in biology textbooks. Here two examples: What libraries can I use to create the envelope curves in blue for the "X"?

I need to use \ProcessList and \SplitArgument with \IfBoolean. Using only \ProcessList does work, but I need to get at the arguments before and after the / -- thus the need for \SplitArgument. The asterisk seems inextricably attached to the second argument in \fooauxai and I cannot seem to pry it loose. As indicated, I've tried some \expandafter experiments.
