marking, headers and 2 columns

marking, headers and 2 columns

[Tobias Hilbricht]

Dear readers of this list,
I would like to typeset a bible-text with ConTeXt. The header should
print the first  and the last verse on that particular page. I used the
commands \marking to mark the verses and \getmarking to setup the
headers as shown in the excerpt below. This works correctly with a
single column layout, but not in a two column layout. The last verse
printed in the headers is not the correct one, the first or the second
on the following page is given.
Is there a work around for this problem? Many thanks in advance for
helpful hints

Yours sincerely

Tobias Hilbricht

i knew it was coming one day ....

add this to cont-new.tex:

\unprotect
     \letvalue{\??mk\??mk\v!kolom:\v!eerste }\getsplitfirstmark
     \letvalue{\??mk\??mk\v!kolom:\v!laatste}\getsplitbottommark
\protect

then this should work (unbalanced only,  and not yet in columnsets)

\definemarking[vers][]

\setupheadertexts[{\getmarking[vers][first] -- \getmarking[vers][column:last]}]

\starttext

\startcolumns[n=2,balance=no]

\dorecurse{10}{\expanded{\marking[vers]{\recurselevel}} 
\recurselevel:\dorecurse{4}{\input ward } \endgraf}

\stopcolumns

\stoptext

The following definition is nicer:

\setupheadertexts
   [\doiftext{\getmarking[vers][first]}
      {\doiftextelse{\getmarking[vers][column:last]}
         {\getmarking[vers][first] -- \getmarking[vers][column:last]}
         {\getmarking[vers][first]}}]
