thank you. I am trying to get some usable OpenType Chinese font for ConTeXt on GNU/Linux.

Typescript font for math script and scriptscript
by juliusross＠gmail.com 04 Oct '24

04 Oct '24

Hi, I was wondering if there is a (good) way to have a specific font for sub/superscripts in mathematics that is different from the main font? I ask because I am working on a variable opentype math font, and it can be made to look a better if the superscripts are made a little bolder. Thanks in advance for any suggestions or examples. JR

Typescript and Math fallback

Dear list, I’m having some issues with my custom type-imp file. I saw in a previous exchange (https://www.mail-archive.com/ntg-context@ntg.nl/msg107516.html) that Hans suggested a way to define a fallback font for math. Based on this, I’ve adapted my custom type-imp: \starttypescriptcollection [alegreya_libertinus] \usetypescriptfile[libertinus] \loadfontgoodies[libertinus-with-alegreya-math]

how can I reset section counter when recursing buffers?
by damien＠thiriet.web4me.fr 03 Oct '24

03 Oct '24

Hello, When I call a buffer with sections several times, I would like to get the same headers numbers for each buffer call. (So, in my MWE twice 1 and 2, not 1, 2, 3, 4) How can I reset the section counter within a dorecurse run? I tried \resetcounter [section] but that is not the good way. I read about \headnumber and \namedheadnumber but could'nt go further. My MWE: \startbuffer \startsection[title={foo}] \input ward \stopsection \startsection[title={bar}] \input knuth \stopsection \stopbuffer \starttext \dorecurse{2}{ % how can I reset chapter number? \getbuffer } \stoptext Thanks, Damien

Values from Lua back to ConTeXt

Hello, what do I have to do so that the values (d1, m1, y1) from the Lua block are returned with Return and the commented out line \date[d=d1,m=m1,y=y1][weekday,{,~},day,{.~},month,{~},year] works in ConTeXt. In other words: how do I do it right? Thank you in advance Greetings Thomas PS. Sorry, I'm a totally novice in Lua. \starttext \startluacode function ddate(s) i = 1 j = 4 y1 = string.sub(s,i,j) i = 5 j = 6 m1 = string.sub(s,i,j) i = 7 j = 8 d1 = string.sub(s,i,j) context("Geht das: %s.%s.%s", d1, m1, y1) -- that works! --return d1, m1, y1 -- that works not! Why? end \stopluacode \def\DDate#1{\ctxlua{ddate("#1")}} \DDate{20241005} %\date[d=d1,m=m1,y=y1][weekday,{,~},day,{.~},month,{~},year] \blank \date[dd,mm,yyyy][weekday,{,~},day,{.~},month,{~},year] \blank \date[d=11,m=7,y=2024][weekday,{,~},day,{.~},month,{~},year] \stoptext

I'm curious what Chinese font(s) you are using with ConTeXt? Are they OpenType font, or TrueType?

Hi, since the latest update, I have differences in line/paragraph/page breaking. I should have expected that vz and granular aren’t stable yet, but maybe it’s a problem in my setup and not even related to that update. * widow and orphan penalties seem to work different, preferring empty lines over single lines. * looseness doesn’t seem to work any more. Where there changes? Hraban
