reduced space below chapter title

reduced space below chapter title

Hi list,

I am attempting to achieve, for every second chapter, to have only one 
line of space between the chapter title and the text that follows.

I looked at the following example in the wiki:

\setuppapersize[A6][A6]
\setupbodyfont[8pt]
\def\MyChapterCommand#1#2%
   {\vbox  to 4cm\bgroup
      {#1\hskip.75em #2}
      \vss
      \egroup}
\setuphead[chapter][header=nomarking, command=\MyChapterCommand]
\starttext
\chapter{test}  \input  tufte
\stoptext

and presumed that I could adjust that to something like 1cm instead of 4cm.

The problem is that when I try to process the original example, I get a 
fatal error at the line which reads \chapter{test} \input tufte.

I'm not sure why that error, but that aside, would the 
\def\MyChapterCommand approach suggested above be the right way to 
achieve my purpose? In other words, I want the text that follows the 
chapter title to follow immediately for specific chapters, rather than 
the considerable vertical space that follows the default setup for 
chapter titles.

Julian

Change

     \def\MyChapterCommand#1#2%

to

     \unexpanded\def\MyChapterCommand#1#2%

or

     \define[2]\MyChapterCommand

Thanks Wolfgang. Clearly that fixes the problem. I also came up with 
another solution which avoids the need to define a MyChapterCommand, by 
first setting up the normal chapter as:

\setuphead
   [chapter]
[header=empty,alternative=middle,style=bold,numbercommand=\groupedcommand{}{\blank[2cm]},after={\blank[3cm]}]

and then setting up a mychapter as:

\definehead[mychapter][chapter]

\setuphead[mychapter][header=empty,alternative=middle,style=bold,numbercommand=\groupedcommand{}{\blank[2cm]},after={\blank[.5cm]}]

That gives me the result I am after as well as maintaining the style of 
the standard chapter head.

You can add a check for odd/even chapter numbers and use only a single 
command.

\startsetups[chapter:after]
   \ifodd\namedheadnumber{chapter}
     \blank[4cm]
   \else
     \blank[1cm]
   \fi
\stopsetups

\setuphead
   [chapter]
   [after=\directsetup{chapter:after}]

% \setuphead
%   [title]
%   [after={\blank[...]}]

\starttext

\dorecurse{10}
   {\chapter{Chapter #1}
    \input knuth}

\stoptext
