(any) neovim users?
by Alan Braslau 15 Oct '22

15 Oct '22

A recent upgrade of the editor neovim leads to the following error when using %&context identification at the head of .tex source files. Error detected while processing BufReadPost Autocommands for "*": Error executing lua callback: /usr/local/share/nvim/runtime/lua/vim/filetype/detect.lua:1248: attempt to index local 'format' (a number value) stack traceback: /usr/local/share/nvim/runtime/lua/vim/filetype/detect.lua:1248: in function 'ft' vim/filetype.lua:2362: in function 'dispatch' vim/filetype.lua:2522: in function 'match' /usr/local/share/nvim/runtime/filetype.lua:12: in function </usr/local/share/nvim/runtime/filetype.lua:11> Has anyone encountered this? (perhaps it has been fixed upstream?) Alan -- Alan Braslau 816 West Mountain Avenue Fort Collins, CO 80521 USA mobile: (970) 237-0957 Conserve energy! ;-)

issues with current latest
by Pablo Rodriguez 15 Oct '22

15 Oct '22

Dear list, I have the following sample: \setuppapersize[A7] \setupinteraction[state=start, color=darkred, contrastcolor=darkred, focus=standard] \starttext \completecontent \startsection[title={sec}, list=(before \&\ now), reference=a] \page \in[a] (after 2022.10.14 10:16) \stopsection \stoptext If I try to compile with LuaTeX (after deleting the cache), I get the following error: lua error > lua error on line 1 in file a.tex: ...tex/texmf-context/tex/context/fonts/mkiv/common-math.lfg:100: attempt to index a nil value (field 'subsets') stack traceback: ...tex/texmf-context/tex/context/fonts/mkiv/common-math.lfg:100: in field 'moveitalics' .../context/tex/texmf-context/tex/context/fonts/mkiv/lm.lfg:103: in main chunk [C]: in function 'dofile' ...ext/tex/texmf-context/tex/context/base/mkiv/good-ini.lua:78: in function <...ext/tex/texmf-context/tex/context/base/mkiv/good-ini.lua:68> (...tail calls...) It is also caused by the minimal: \starttext \null \stoptext And with the first source, \in hyperlink doesn’t work at all. Sylvain reported an issue with the \completecontent list (not honoring "focus=standard"), but with current latest the \in hyperlink doesn’t work at all. Could anyone confirm the issues? Many thanks for your help, Pablo

atan2 function
by Thangalin 15 Oct '22

15 Oct '22

Hi there, How is atan2 called? I rolled my own as follows: % SOT \startuseMPgraphic{HexGridBaseGraphic} vardef atantwo( expr ax, ay, bx, by ) = save theta; numeric dx; numeric dy; numeric theta; dx := bx - ax; dy := by - ay; theta := 0; if (dx > 0): theta := atan( dy / dx ); elseif (dx < 0) and (dy >= 0): theta := atan( dy / dx ) + pi; elseif (dx < 0) and (dy < 0): theta := atan( dy / dx ) - pi; elseif (dx == 0) and (dy > 0): theta := pi / 2; elseif (dx == 0) and (dy < 0): theta := -pi / 2; fi; %theta := atan( dy, dx ); theta enddef; % EOT When this runs, the expected result is generated: https://pdfhost.io/v/xdNxANU18_scaled When uncommenting "atan( dy, dx )", an unexpected result is generated: https://pdfhost.io/v/QdfU89IL._scaled Is atan with two parameters supposed to behave like atan2? Cheers!

lmt_outline not rendering properly
by Jacob Kauffmann 14 Oct '22

14 Oct '22

Dear list, attached is an example taken from the luametafun manual. The letter o looks odd. When I compile the manual the examples in section 4 look also bad (different font; page 10 attached). It seems like the paths miss one point. This is with the latest version 2022.09.11 20:44. Cheers, Jacob

How to make something appear to the right of every paragraph?
by Joel 14 Oct '22

14 Oct '22

I'd like to add some area for readers to write in the margins of some text. This would leave three lines, like this to the right of the text. __________________ The passage would take up about the left 60% of the text and the margin note space about 30% of textwidth, so no need to use the margins. Though its easy for me to implement this code using some \thinrules and manually dropping macros in the text, is there some way ConTeXt can be told to just add them to right of every paragraph (at the start of the paragraph)? Sample: This is some text ________ that is written in ________ the passage and ________you can see the th-ree lines to the right.The text in the para-graph continues eventhough there arejust three lines tothe right. Here is another par- ________agraph. ________ ________ Here is yet another ________paragraph. You can ________see it also has the ________three liens. This is just for a segment of the book, not every paragraph in the book. --Joel

LMTX generates PDFs with non-working fonts on real printers
by Leah Neukirchen 13 Oct '22

13 Oct '22

Hi, I use LuaMetaTeX 2.10 20220918 + ConTeXt LMTX 2022.09.11. Here's a tiny test document, I disabled PDF compression but it also doesn't work with the default settings. \setupbackend[level=0,compresslevel=0] \starttext Just a line of text. \stoptext When I print this "directly" (i.e. sending the raw PDF to the printer) on a Ricoh MP3053 or on a Samsung CLP-680DW, I just get an empty page. The PDFs render fine on every PDF reader I could find. Conversion to PostScript with pstopdf (poppler-22.07.0) and then sending the PS renders the document correctly on the printer. PDFs generated directly from Context MKIV from TeXLive 2022 using LuaTeX 1.5 render fine on these printers. I've also printed PDFs from pdfTeX in the past fine. I attached the non-working 'foo.pdf.mkix' and the working 'foo.pdf.mkiv' file. I tried to disable font subsetting to debug this further, but I couldn't figure out how to do it. Any ideas what I should try to help debug this? cu, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

\text{...} inside \sqrt is tiny
by Gavin 13 Oct '22

13 Oct '22

Hi List, When I use text inside a radical, the text is script-script size. $\text{Radius} = \sqrt{\text{Area}/\pi}$ It should be normal size. Any ideas for a fix? I stumbled on this issue when working with \units, but it is not specific to units. Thanks! Gavin

\quotation, protrusion and linebreaking
by Leah Neukirchen 13 Oct '22

13 Oct '22

Hello, I noticed the following problem: \showframe \startluacode fonts.protrusions.vectors.pure[0x201C] = { 1, 1 } \stopluacode \definefontfeature[default][default][protrusion=pure] \setupalign[hanging] \starttext This text is unquoted. “This text is quoted manually.” \quotation{This text is quoted by a macro.} This is a very long line followed by a nice linebreak, very supercalifragilisticexpialidocious. This is a very long line followed by an ugly linebreak, not \quotation{supercalifragilisticexpialidocious} \stoptext The macro-quoted text is not protruded. I fixed this locally with a macro \def\q#1{\protrusionboundary1\quotation{#1}} Should this be default? But the missing hyphenation I have to add myself with \-. Ideas? -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

regular online meet-up
by Henning Hraban Ramm 12 Oct '22

12 Oct '22

You’re invited to join on Wednesday, October 12th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://v34h.de/ctxmtg) ConTeXt users of all levels are welcome! Next meeting will be on November 9th. (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter at a time, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban
