setuphead question

Hello,

In the example below...

----------------------------------------------------

%\def\myCommand#1#2{}
\def\myCommand#1#2{#1 #2}
%\def\myCommand{}

\setuphead[chapter]
    [number=yes,
     align=middle,
%  anyotherparameter=whatever,
    command=\myCommand]
%    command=]

\starttext

\startfrontmatter
    %\placecontent
    \completecontent
\stopfrontmatter

\startbodymatter
    \chapter{chapter one}

    \dorecurse{5}{\input tufte\par}

    \chapter{chapter two}

    \dorecurse{5}{\input douglas\par}
\stopbodymatter

\stoptext

----------------------------------------------------

... how do you define myCommand so

\setuphead[chapter]
    [(any other parameter settings),
    command=\myCommand,
    (any other parameter settings)]

is equal to

\setuphead[chapter]
    [(any other parameter settings),
    command=,
    (any other parameter settings)]

i.e. with any other parameter settings remaining active.

In the example above, with align=middle and

- \def\myCommand#1#2{} the ToC and chapter heads are blank
- \def\myCommand#1#2{#1 #2} the ToC and chapter head alignment is lost
- \def\myCommand{} the ToC and chapter head alignment is lost


Thanks,
Alan

This is not possible because ConTeXt use the \normalplacehead command
by default (even for "command=," as fallback) and this is where the align
key is used, with your \myCommand this \normalplacehead is repleaced
and the align key and many of the others are no longer used by ConTeXt.

The best thing is to key that are used in higher level macros like style, color
or \numbercommand and \textcommand because they act independent of
the command key.

Re: setuphead question

i also have a question;  why can't i use different fonts in

\def\myCommand#1#2{{\ss\sc #1}{\rm\sc #2}{\ss\sc\bf #1}{\rm\sc\bf #2}}
\setuphead[part][command=\myCommand]

the font commands are simply ignored.  I don't want to have to resort to 
using numberstyle and textstyle.

Thanks

You code works but the style and number/textstyle values act
as part of #1 and #2 and you have to set them to nothing to
get your own settings.

\setuphead[part][command=\myCommand,style=]
