chapter-like headings with separate numbering

chapter-like headings with separate numbering

[Sanjoy Mahajan]

I'm experimenting with making a heading that is like a chapter in format
but has its own numbering (or lettering).  The purpose to have an
interlude, or extended example, every few chapters.  The following
almost-minimal example almost does so.  However, the second interlude is
numbered with 'A' instead of 'B'.  Is there a missing key=value pair, or
is the approach completely wrong?

\definesection[nc]
\setupsection[nc][conversion=Characters]
\definehead[interlude][section=nc,default=chapter]
\setuphead[interlude][incrementnumber=yes]

\starttext

\title{Contents}
\placelist[chapter,interlude]

\chapter{Chap 1}

\interlude{Interlude 1}

\chapter{Chap 2}

\interlude{Interlude 2}

\stoptext

It seem that interlude is like a section,
so it's correct that at every chapter there is a reset of the
alphabetical counter

I meant the interludes to be long examples based upon the preceding few
chapters.  So I think of interludes as at the same level as a chapter.
But your comments suggests an idea: Is there a key=value pair that says
"Don't ever reset the interlude counter (but do reset section numbers
when a new chapter appears!)?"

I did, I did!  It sometimes requires a mix of luck and skill in
selecting the search phrases.  As when using a dictionary to check the
spelling of a word -- needs enough luck and skill to be in the vicinity.

If you want to refer to your problem there is a better definition
for \problem.

\definecomplexorsimpleempty\problem

\def\complexproblem[#1]%
   {\doglobal\increment\ProblemNumber
    \Problem[#1]{\ProblemNumber}}

An enumeration passes the duck test [1] for headings, so ...

[1] http://en.wikipedia.org/wiki/Duck_test

\defineenumeration
 	[interlude]
         [before=\page,conversion=Characters,way=bytext,list=interlude,
          text={Interlude }]


\defineenumeration
 	[interludeA]
         [before=\page,conversion=Characters,way=bytext,list=interludeA,
          text=, listtext=,
          title=yes, titleleft=, titleright=]

\starttext

\title{Contents}
\placelist[chapter,enumeration:interlude,enumeration:interludeA]

\chapter{Chap 1}

\interlude{Interlude 1}

\interludeA{{Interlude 1}}

\chapter{Chap 2}

\interlude{Interlude 2}

\interludeA{{Interlude 2}}

\stoptext

Re: chapter-like headings with separate numbering

[Sanjoy Mahajan]

Thanks, that's a nice approach.  It doesn't fully pass the duck test:
The page headlines come from the chapter titles, even in the interludes.
Here is an example.

\startsetups[chheadline]
  {\ss\it Chapter \getmarking[chapternumber].\quad\getmarking[chapter]}
\stopsetups
\setupheadertexts[\setups{chheadline}][pagenumber]

\defineenumeration
	[interlude]
        [before=\page,conversion=Characters,way=bytext,list=interlude,
         text={Interlude }]

\defineenumeration
	[interludeA]
        [before=\page,conversion=Characters,way=bytext,list=interludeA,
         text=, listtext=,
         title=yes, titleleft=, titleright=]

\starttext

\title{Contents}
\placelist[chapter,enumeration:interlude,enumeration:interludeA]

\chapter{Chap 1}

\interlude{Interlude 1}

\interludeA{{Interlude 1}}

\chapter{Chap 2}

\interlude{Interlude 2}

\interludeA{{Interlude 2}}

\stoptext

Then beat the hell out of it, until it starts behaving like a duck. 
The main trouble is that descriptions do not set any marking, and there 
are not enough hooks to set a mark. But we can still use poor man's marks: 
macros!

% First we need two types of headings: for chapters and for interludes

startsetups[headline:chapter]
   {\ss\it Chapter \getmarking[chapternumber].\quad\getmarking[chapter]}
\stopsetups

% Marking version does not work ... see comment below
% \definemarking[interlude]
% \definemarking[interludenumber][expansion=yes]
%
% \startsetups[headline:interlude]
%   {\ss\it Interlude 
\getmarking[interludenumber].\quad\getmarking[interlude]}
% \stopsetups

% So we define our own marks

\def\interludeMARK{empty}
\def\interludenumberMARK{empty}

% And a second version of heading
\startsetups[headline:interlude]
   {\ss\it Interlude \interludenumberMARK.\quad\interludeMARK}
\stopsetups

% The header texts need to switch between the two
\setupheadertexts[\setups{headline:\CURRENTDIVISION}][pagenumber]
\setuppagenumbering[location=]

% We start with current division as chapter
\def\CURRENTDIVISION{chapter}

% Provide an option of switching on interlude pages
\couplepage[interlude][before={\gdef\CURRENTDIVISION{interlude}}]

\startsetups interlude
   \page
   \pagetype[interlude]
\stopsetups

% And switch back on chapter pages
\setuphead[chapter][before={\page[right]\def\CURRENTDIVISION{chapter}}]


% Now define the enumeration
\defineenumeration[interlude]
                   [before=\setups{interlude},
                    conversion=Characters,way=bytext,list=interludeA,
                    text=, listtext=,
                    title=yes, titleleft=, titleright=,
                    titlecommand=\interludemarking]


\def\interludemarking#1%
   {\gdef\interludeMARK{#1}%
    \global
    \edef\interludenumberMARK{\getnumber[\currentdescriptionnumber]}%
    #1}


% Ideally, I would have liked to use marks, but this does not work
% Probably because we are inside a box
% \def\interludemarking#1%
%   {\marking[interlude]{#1}%
%    \marking[interludenumber]{\getnumber[\currentdescriptionnumber]}%
%    #1}


\starttext

\title{Contents}
\placelist[chapter,enumeration:interlude,enumeration:interludeA]


\chapter{Chap 1}
   \dorecurse{5}{\input knuth \endgraf}

\startinterlude {Interlude 1}
   \dorecurse{5}{\input knuth \endgraf}
\stopinterlude


\chapter{Chap 2}
   \dorecurse{5}{\input knuth \endgraf}

\startinterlude {Interlude 2}
   \dorecurse{5}{\input knuth \endgraf}
\stopinterlude

\stoptext


At this stage I am not sure whether you gain anything by using 
enumerations. You get predefined support for numbering and lists, but that 
is not too hard to write on your own.
