numbering questions

numbering questions

[Henning Hraban Ramm via ntg-context]

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

\stopYear

\stoptext
-----

I can't test right now but would something like

\setuphead[Day][sectionsegments=Day:Month:Year]

help?

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.

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!

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

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

Thank you, Wolfgang!
I _knew_ ConTeXt would be able to handle my requirements! ;D
It’s wikified now (at \setuphead and \defineconversion).
