> \determineheadnumber[section]
Thanks for mentioning that command, which I'd been looking for. I
couldn't quite get it to work, but reading the code near its
definition helped me solve another problem. Each chapter has a
section for exercises, and each exercise is a subsection with a short
title (a few words). e.g.
\exercise{Batteries}
What is the cost of energy from a 9V battery? From a wall socket (the
mains)?
I want the exercises to be numbered just by the exercise number
(e.g. 7), not for example 1.6.7 (if the exercises are the 6th section
in chapter 1). Hence this setup:
\definehead[exercise][subsection]
\def\choptwo#1.#2.{}
\def\processtwo#1{\expandafter\choptwo#1\relax}
\setuphead[exercise][style=italic,
numbercommand={\processtwo{\currentheadnumber} \gobbleoneargument}]
If there's an easier way using \determineheadnumber, I'll be happy to
use it instead but the above probably fragile hack works for me.
The more obvious try
\def\choptwo#1.#2.{}
\setuphead[subsection][numbercommand={\expandafter\choptwo}]
produced 200 lines of complaint, starting with:
ERROR: Argument of \choptwo has an extra }.
In the following minimal example of my attempt to use
determineheadnumber, the subsection numbers are missing (instead of
being the chapter number):
\setuphead[subsection]
[numbercommand={\determineheadnumber[chapter] \gobbleoneargument}]
\starttext
\chapter{One}
\section{A1}
hi
\subsection{B1}
hi
\subsection{B2}
hi
\stoptext
>>
>> \setuphead[section]
>> [command={{{\determineheadnumber[section]}
^^^^
> one opening brace too much
That's why I want the editor to insert } for me automatically when I
type { (in the earlier thread about AUCTeX/Emacs).
