Syntax highlighting using LMTX
by Thangalin 15 Dec '21

15 Dec '21

Hi all, There are a few technical hurdles with using the t-vim module in LMTX. First, users need to install the module using externally defined shell scripts. Second, it's awkward to communicate to users how to install it, especially for Windows users. Third, it likely requires installing vim, as a separate step. Fourth, making general-purpose XML setups that optionally rely on syntax highlighting when it is an optional install is a little laborious. If installing a module was as easy as "install.sh --module=t-vim" then that would leap over most hurdles. Although there'd still be a dependency on installing vim. Of course, it'd be pretty sweet if ConTeXt itself could automatically install the necessary module when encountered (or provide a command-line option to grant permissions to do so), but I understand that that would be a hefty undertaking. The following pages discuss creating syntax highlighters: - https://wiki.contextgarden.net/Verbatim_text - https://wiki.contextgarden.net/Custom_pretty_printer - https://tex.stackexchange.com/a/333620/2148 How would you go about creating a syntax highlighter for Java that can work with LMTX? Specifically, I'd like to know: - Where do the files need to be saved? (e.g., tex/texmf-context/tex/context/base/mkiv/) - What file name is required? (e.g., buff-imp-java.lua and buff-imp-java.mkiv) - How is the parser loaded? (e.g., \loadmarkfile{buff-imp-java} or \installprettytype[java][java]) Ultimately, this is going to be used with XML snippets along the lines of: <pre><code class="language-java">public final class Example { public static void main( String args[] ) { } }</code></pre> Having the ability to dynamically define the requisite start/stop environments based on the class attribute would be rather convenient. Thank you!

descriptions -- symbol between head and text
by denis.maier＠unibe.ch 15 Dec '21

15 Dec '21

Hi, is there a way to get some text between the head and the text of a description. Enumerations have stoppers, but I couldn't find an equivalent setting for descriptions: The output should look roughly like this: ABC: asdfasdfasdf jklöjklööjklö CDE: asdfasdfasdf jklöjklöjklöö Denis %%%%%%%%%%%%%%%%%%%%%%%%% \definedescription[deflist][ headstyle=normal, style=normal, alternative=hanging, width=fit, margin=1cm, distance=0em, ] \starttext \startdeflist{ABC} \input knuth \stopdeflist \startdeflist{CDE} \input knuth \stopdeflist \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%

About margin notes

Hi all: I send this minimal example: \mainlanguage [es] \definefontfamily [mainface] [serif] [Gentium] \setupbodyfont[mainface] \setuppagenumbering[alternative=doublesided, location={footer,right}] \setuplayout[textwidth=12cm,margin=2.5cm] \setupmargindata[inmargin][style={\tfx\em}, location=outer,align=flushouter] \starttext \chapter{Introduction} \input{tufte} \input{tufte}\inmargin{This is the first margin note} \input{tufte} \input{tufte} \section{Whe start here} \input{knuth}\inmargin{This is another margin note} \input{tufte}\inmargin{This is another note in margin} \input tufte \chapter{Second chapter} \section{First section} \input{tufte} \stoptext Notes that appear in the right margin are justified, aligned with the text, but not the note in the left margin. How could I do this? Thanks. M. González.

Regular online meet-up
by Henning Hraban Ramm 14 Dec '21

14 Dec '21

Hi all, already for a while I wanted to suggest a regular online meet-up, just to chat or discuss ConTeXt and the world. Participants of the just finished meeting already know the BigBlueButton “room”, and without the difficulty of a auditory in presence and a weak DHCP, we should have even less problems with it. I’d offer this monthly, 2–3 hours, and let’s see if it stands the test. Now, if you’d like to participate, which times would fit you (weekdays, daytime...)? Warm regards, Hraban

Switching to righttoleft without changing margins of delimited text
by denis.maier＠unibe.ch 14 Dec '21

14 Dec '21

Hi, I have the following example: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupdelimitedtext[blockquote] [leftmargin=1.5em,rightmargin=0em,] \starttext \input knuth \startblockquote \input knuth \stopblockquote \startblockquote \righttoleft \input knuth \stopblockquote \input knuth \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \righttext seems to change the locations of the margins, i.e. leftmargin becomes rightmargin and vice-versa. That may be nice in some situations, but I need to keep the margins where they are. Is there a way to do this? (Maybe \righttoleft is the wrong command?) I thought I could define a new rtlblockquote with appropriate settings, like so: \definedelimitedtext[rtlblockquote] \setupdelimitedtext[rtlblockquote] [leftmargin=0em,rightmargin=1.5em,before={\righttoleft}] But maybe there's a better way. Any hints? Denis

Re: [NTG-context] how to setup path of ConTeXtLMTX for MacVim?
by Jeong Dal 14 Dec '21

14 Dec '21

Dear John, Nicola, I created a file context.vim under the folder ~/.vim/after/ftplugin/ which contains map <C-h>><Esc> :w<CR>:!ConTeXt<CR> let g:context_mtxrun = 'PATH=$HOME/ConTeXtLM/tex/texmf-osx-64/bin:$PATH mtxrun' let g:tex_flavor = "context" The result is 1. using “:ConTeXt” issued an error message: “E492: not an editor command: ConTeXt 2. using “make” issued an error message: "No targets specified and no makefile found. …" Pressing C-h, compiling started and succesfully ended. However, it use /usr/local/texlive/… not LMTX tex folder. Without context.vim, “:ConTeXt" and “:make" worked fine. I’ll do more test. Thank you. Best regards, Dalyoung

TeXWorks and synctex
by Bruce Horrocks 13 Dec '21

13 Dec '21

I'm having trouble getting the new synctex to work on a Mac. I've completely re-installed MacTeX and TeXWorks and synctex works fine for LaTeX documents. But for ConTeXt no combination of magic lines etc will work for me. The symptoms are... nothing - no errors but no synching, either way. Q1: is there a log file created somewhere or a debugging flag that can be turned on which will tell me what is happening when I try to jump from PDF to editor or vice versa? Q2: Is this the same error as reported at the bottom of https://wiki.contextgarden.net/SyncTeX ? Or has that been fixed? PS: \enabletrackers[system.synctex.visualize] works as expected - i.e. the .synctex file seems to be correct. — Bruce Horrocks Hampshire, UK
