Problem with large space after section header

Problem with large space after section header

[Jason Earl]

[-- Attachment #1: Type: text/plain, Size: 747 bytes --]


I am having a bit of a problem with some documents that I am trying to
lay out in Context.  The idea is that section contents are formatted in
two columns, but in some cases Context leaves a huge space between the
section header and the content.

I have included a sample context file (test.tex) and the output I get
from running:

context test.tex

using the newest version of context minimals.  I expect "1.2.1 Test
SubSection 1" and "1.2.2 Test SubSection 2" to be on the same page as
"Problem Header," but, as you can see, they aren't.

I appreciate any help in sorting this out.

I'm new to Context, and not particularly experienced in typesetting
either, so if you have any other advice I would appreciate that too :).

Thanks,
Jason Earl

This is a very small subsection.  It needs to be a little bit longer
than just one sentence.  Maybe just a tad bit longer would help.  I
want to make sure I have an excellent example.

You can force a page break before the second section with

\page
\section{Problem Header}

to keep the header and the columns together.

OK, that's embarrassing.  I tried using \page[no] after the \section
header, but it did not occur to me to put a manual break before the
header.  That worked perfectly.

In my defense, part of the reason that I did not think of putting in a
manual page break before the section is that my real context documents
are generated from a script, and I did not want to have to process the
output by hand to solve these sorts of problems.  I was hoping for some
sort of magic that I could put after every section heading that would
make Context try harder to keep the content close to the header.

However, while I don't pretend to be an expert at typesetting I do
understand that automating this stuff is hard, and sometimes there is no
real way to fix issues like this.  If I have to do a little hand
massaging of the output that's acceptable.

Thanks for the help,

Jason

In an automated setup, you can try

\setuphead[section][before={\blank\testpage[4]}]

\testpage[n] tests if there is enough space to put n lines in the current 
page. If not, it insearts a pagebreak. Play around with n to see what 
gives best result.

Thank you so much.  That looks like it is going to solve the most
problematic spaces without having to manually insert page breaks.  In
fact, to my untutored eye even without playing with the numbers it looks
perfect.  That was precisely the magic I needed, and it even came with
an explanation that should help me solve similar problems myself in the
future.

Thanks to Wolfgang for responding as well.  I am sorry I was not more
clear with my original report.

Thanks again,
Jason
