About margin notes
by MANUEL GONZALEZ SUAREZ 14 Dec '21

14 Dec '21

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

tikzplot displacement result

HI! I’m trying to fit the funktion in the right place in this plot but it seems to get displaced. What is wrong with the code? Is there a way to do this in Metafun?

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

Typo in m-tikz
by Aditya Mahajan 13 Dec '21

13 Dec '21

Hi, There is a typo in m-tikz.mkxl (possibly a carry-over from t-tikz.tex). The module ends with a spurious `\stopmodule`: https://github.com/contextgarden/context-mirror/blob/fe714093ebb95e4a870282… (Or rather, the corresponding `\startmodule` is missing). This causes an interesting error message on the following test file: \usemodule[tikz] \usetypescriptfile[euler] \definetypeface[mainfont][rm][serif][pagella][default] \definetypeface[mainfont][mm][math] [pagellaovereuler][default] \definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8, features=none] \setupbodyfont[mainfont,11pt] \starttext $\dfrac{1}{2}$ \stoptext which gives: system > module wrapping error in 'tikz' close source > level 2, order 67, name '/opt/luametatex/texmf-context/tex/context/modules/mkxl/m-tikz.mkxl' open source > level 2, order 68, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-euler.mkiv' open source > level 3, order 69, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-texgyre.mkiv' close source > level 3, order 69, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-texgyre.mkiv' open source > level 3, order 70, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-dejavu.mkiv' close source > level 3, order 70, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-dejavu.mkiv' suggestion > use \withcedilla instead of \c suggestion > use \withcaron instead of \v close source > level 2, order 70, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-euler.mkiv' open source > level 2, order 71, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-texgyre.mkiv' close source > level 2, order 71, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-texgyre.mkiv' fonts > typescripts > unknown library 'pagellaovereuler' open source > level 2, order 72, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-dejavu.mkiv' close source > level 2, order 72, name '/opt/luametatex/texmf-context/tex/context/fonts/mkiv/type-imp-dejavu.mkiv' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-rm-tf-0--0' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-mm-mr--3' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-mm-mr--2' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-mm-mr--1' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-mm-mb--3' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-mm-mb--2' fonts > defining > unable to define 'unknown' as 'mainfont-11pt-mm-mb--1' tex error > tex error on line 10 in file ./test.tex: Math error: parameter 'fractionrule' in style 2 is not set <line 3.10> $\dfrac{1}{2}$ And since tikz is a latex module, in the true LaTeX spirit, the error goes away (for obvious reasons) if I move the \usemodule[tikz] to after the font definitions. It took quite a while to figure out what is happening. Aditya

Nested $$ in inline math
by Jack Hill 13 Dec '21

13 Dec '21

Dear list, I was playing around and found that nesting $$s inside of \m blocks typesets the code as text. I can't find anything about this on the wiki or in the math-mkiv manual, so I'm asking whether this is supported behaviour or just a bug? Jack \starttext % All the same \mathematics{math $text here$ math} \\ \math{math $text here$ math} \\ \m{math $text here$ math} \\ \m{math \text{text here} math} \\ \stoptext
