Placing a section ending depending on odd/even sectionnumber

Placing a section ending depending on odd/even sectionnumber

[Willi Egger]

Hi,

now I have another hurdle to be taken :-) — Depending on the odd or even number of the section I have to place an ornament at the end of the section.

I have sofar the following setup:

\define\stopmysection
  {\setups{endsection}}
	 

\startsetups endsection
	\doifelse
		{\currentheadnumber} %{\headnumber[section][current]}{odd}
		{even}
 	{\vfil
 		{\bf End of even numbered section}
 		\stopsection%
		}
		{\vfil
			{\bf End of odd numbered section}
			\stopsection%
		}
\stopsetups

\starttext

	\startsection[title=Ward]
	
		\setuppagenumbering[conversion=romannumerals]
	
		\input ward
	\stopmysection

	\startsection[title=Knuth]
		\setuppagenumbering[conversion=numbers]
	
		\input knuth

	\stopmysection

\stoptext

However the the evaluation of the sectionnumber results always in “false”, having therefore always odd as a sectionending.

What to change in order to get the desired result?

Kind regards

Willi

You have two problem:

1. To get the current value for \currentheadnumber you have use 
\determineheadnumber[section] before you use it but the example below 
shows a better method.

2. What you do with \doifelse{...}{even} is to compare the numeric value 
of the section with the string "even" which is always false. To check 
whether the value is odd or even you have to use the \ifodd command.

%%%% begin example
\startsetups [section:odd]
   \vfill
   \bold {End of odd numbered section}
\stopsetups

\startsetups [section:even]
   \vfill
   \bold {End of even numbered section}
\stopsetups

\startsetups [section:end]
   \ifodd\namedheadnumber{section}
     \directsetup{section:odd}
   \else
     \directsetup{section:even}
   \fi
\stopsetups

\setuphead
   [section]
   [aftersection=\directsetup{section:end}]

\starttext

\startsection[title=Ward]
\input ward
\stopsection

\page

\startsection[title=Knuth]
\input knuth
\stopsection

\stoptext
%%%% end example

Wolfgang, thank you so much for your help!

Hm, when reading your explanation I start to understand my short cut in thinking about solving the problem.

I will build it into my project…

Thanks and kind regards
Willi
