A happy new year to everyone! I’m playing with some examples of section numbering. * Is there a setup to influence the order of number segments?

I can't test right now but would something like \setuphead[Day][sectionsegments=Day:Month:Year] help? Duncan On Sat, 31 Dec 2022 at 17:24, Henning Hraban Ramm via ntg-context < ntg-context@ntg.nl> wrote:

I forgot to mention that I tried this. It doesn’t work (while it would be the most easy syntax, I guess), you can set the segments only in order of hierarchy. Hraban

I thought sectionsegments=section:chapter would work, but it doesn’t.

The easy part is to have the leading zeros, but I cannot get it working with numbercommand or deepnumbercommand. \startluacode function document.leadingzeros(str) local lzeros = 3-str:len() return ("0"):rep(lzeros) end \stopluacode \unexpanded\def\lzeros#1% {\cldcontext{document.leadingzeros("#1")}}

\setupheadnumber[chapter][3] % will start with 4 I hope it helps. »Einen guten Rutsch ins Neujahr!« Happy New Year to all! Pablo

Same. With numbercommand, Lua gets "\s and can’t handle it, with deepnumbercommand it gets "1-\m". Is this a catcode issue?

Thank you, that works.
I hope it helps. »Einen guten Rutsch ins Neujahr!«
Dito! (In proper German that would be just “Guten Rutsch” or “Guten Rutsch ins neue Jahr”; Neujahr ist just the name of the holiday.) All the best, Hraban

You need a new prefix-set to rearrange the order of the sections. %%%% begin example \defineprefixset [reverse-section] [section,chapter] [] \defineprefixset [reverse-subsection] [subsection,section,chapter] [] \setuphead [section] [sectionset=reverse-section] \setuphead [subsection] [sectionset=reverse-subsection] \starttext \startchapter [title={A}] \startsection [title={B}] \startsubsection [title={C}] \stopsubsection \startsubsection [title={D}] \stopsubsection \startsubsection [title={E}] \stopsubsection \stopsection \startsection [title={F}] \startsubsection [title={G}] \stopsubsection \startsubsection [title={H}] \stopsubsection \startsubsection [title={I}] \stopsubsection \stopsection \stopchapter \stoptext %%%% end example
* How can I format the segments, e.g. to get two or three digits each (leading zeros)?
You can create your own conversion format. %%%% begin example \startluacode interfaces.implement { name = "FourDigits", public = true, arguments = "string", actions = function(s) context("%04d",tonumber(s)) end } \stopluacode \defineconversion [FourDigits] [\FourDigits] \setuphead [chapter] [conversion=FourDigits] \starttext \startchapter [title={Chapter}] \stopchapter \stoptext %%%% end example Wolfgang
Thank you, Wolfgang! I _knew_ ConTeXt would be able to handle my requirements! ;D It’s wikified now (at \setuphead and \defineconversion). Hraban Am 01.01.23 um 11:27 schrieb Wolfgang Schuster:
