[NTG-context] numbering questions

[Henning Hraban Ramm]

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.e. can I 
have “section.chapter.part“ instead of “part.chapter.section”?

* How can I format the segments, e.g. to get two or three digits each 
(leading zeros)?

* I can force a section number with “ownnumber”, but the next one is 
back in the previous scheme. Itemize has “start”. How can I start 
section chapter numbering at 3 (or -1 or whatever; I know I can start at 
0 with “zero”) and let ConTeXt continue from there?


My example tries to (ab)use the section numbering for a date (e.g. for a 
diary):

-----
\definestructureconversionset[default][n,n,month,n][n]
\definestructureseparatorset [default][-,-,-,-]

\definehead[Year][chapter]
\definehead[Month][section]
\definehead[Day][subsection]

\define[2]\TitleCmd{#1} % number only

\setuphead[Year,Month,Day][number=yes,page=no,command=\TitleCmd]
\setuphead[Year][page=yes]
%\setuphead[Month][]
\setuphead[Day][style={\ss\bf}]

\def\Dummycontent{
     \dorecurse{12}{
     \startMonth
     New Month.

     \dorecurse{5}{
     \startDay
     Another day.

     \stopDay
     }

     \stopMonth
}}

\starttext

\startYear[ownnumber=2023,title=This]
A new year begins.

\Dummycontent

\stopYear

\startYear
Next year.

\Dummycontent
