how can I reset section counter when recursing buffers?

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
by Thomas Meyer 03 Oct '24

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, Is there any way to automatically control the spacing between Chinese and non-Chinese characters? I noticed that there is a tracker that tracks character types and annotates them. But I don't know much about lua and the underlying tex. Any suggestions would be greatly appreciated. For example, glue is automatically added between Chinese characters and English or numbers. input: 今天出去买菜花了5000元。 will get: 今天出去买菜花了 5000 元。 ---------------------------------- input: 新MacBook Pro有15%的CPU性能提升。 will get: 新 MacBook Pro 有 15% 的 CPU 性能提升。 Muyik

Metapost and write to file...

Hello! I think that I am missing something here. I should use an older file of mine, where some data calculated by METAPOST should be written to a file. However in the latest version of CONTEXT luametatex exits with error code 1 when running this minimal example. What has changed? Kind regards Willi \startuniqueMPgraphic{Test} draw fullcircle scaled 3cm; write "Hello World!" to "data.txt"; write EOF to "data.txt"; \stopuniqueMPgraphic \starttext \useMPgraphic{Test} Import data from \quotation{data.txt}: \blank \input data.txt \stoptext

“breaking news”
by Henning Hraban Ramm 01 Oct '24

01 Oct '24

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
