ToC filler dots not aligned
by Schister, Roman 15 Oct '22

15 Oct '22

Hi, If I typeset a table of contents with the latest version of ConTeXt on my computer (2022.09.11 20:44 LMTX), the filler dots used in list alternative C aren’t aligned (i.e., they don’t end flush next to the page number). Typesetting the same file with the online version on ConTeXt Garden (2021.10.28 10:19 LMTX) results in the filler dots being right-aligned with the page numbers (as they should). I had a similar issue back in April 2021 which got resolved by an update. Since I haven’t updated in a while, I can’t say in which version the behaviour changed back, unfortunately. Here’s a working example of my code: \setupcombinedlist[content][alternative=c] \starttext \completecontent \chapter[title={First chapter}] \chapter[title={Second, longer chapter}] \chapter[title={Third chapter}] \stoptext Any help is greatly appreciated. Thanks and best wishes, Roman

(any) neovim users?

A recent upgrade of the editor neovim leads to the following error when using %&context identification at the head of .tex source files.

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 14 Oct '22

14 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 13 Oct '22

13 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
