Hello,
I would like to have the whole (sub)section on a single page unless it doesn't fit on one page (in this case I don't mind if it starts on a new page or simply continues on the old one, but it should break somewhere, that's why putting the content into a \vbox doesn't solve the problem).
This is perhaps already described somewhere in the documentation, but I don't know where to look for it (well, I could start reading the source code for split=yes; perhaps \vsplit could help, but don't know how exactly to apply it). I can solve the problem temporary by manually placing page breaks, but I guess that there exists some really short, simple & elegant solutions for it.
It doesn't need to automatically determine the subsection boundaries automatically (although this would be great), so I can write something like this:
\startmaterialforonepage \subsection{split only if too long for one page} \dorecurse{10}{whatever comes here \dots } \stopmaterialforonepage
Thank you, Mojca

Do you want something like this?
\long\def\startmaterialforonepage#1\stopmaterialforonepage% {\setbox0\vbox{#1}\ifdim\ht0<\textheight \page\fi #1}

Thak you, Taco. Yes, this is almost exactly what I wanted to do, except that I would substitute \ifdim\ht0<\textheight with \ifdim\ht0<\theremainingpageheight
How/where can I get \theremainingpageheight? I saw some strange "keywords" like \pagegoal, \pagetotal spread through the source, ... but I have no clue what they are for and if they have anyting to do with what I'm looking for.
Thans a lot, Mojca

that's always tricky, because it's not really possible to determine the rest of the available space without entering the output routing, which then spoils spacing
(there is \testpage[n] with n being a minimal number of lines, so, \testpage[10] will move to the next page if there are less than 10 lines)

Thank you, Hans. I have to refresh my knowledge about the syntax and I'll try it out. Making \setbox0\vbox{#1} and then executing the \testpage with "ceil(ht0 / lineheight)" should then work OK, I hope.
I understand the problem of the approach that I asked for: as soon as someone enters a \vfill(l) or \vss, it's approximately impossible to determine where the text on the page ends. But in the first approximation I would be satisfied with the empty space that would remain if the document ended at that specific place.
That information is also very valuable when trying to put pictures on slides, where picture has to be as big as possible, but still has to fit on the space under the title (I tuned them manually, which was OK for just a couple of slides).
Thank you, Mojca

even that is tricky, imagine your method (along the lines):
- \setbox0\vbox{\startitemize ... \stopitemize} - measure and decide if \page is needed - \unvbox0
putting something in a box prevents for instance \blank looking back and getting the spacing right (context goes to a large extent to get spacing right)
<text ... > <blank or interpar space and if needed depth correction> <vbox with embedded blanks leading to too much whitespace> <text .... preceded by tex's auto skips that can't look into the box>
even unvboxing does not help since esp the top of box damage has been done and is irreversible unless you do clever trickery
officially you need something
\startboxed ... \stopboxed
where the start/stop do some housekeeping
what you can try is to define an instance of framedtext (\startframedtext \stopframedtext) with no offsets and frame since that macro does reasonable job on spacing and still keeps things together

Is there any nice ConTeXt way of doing the above?

\testpage[1] % one line, [3] three lines

Sure, but I'm not asking for n lines, but for a dimension. Oh, if I read the source correctly, \testpage[0][\dimexpr\dp0+\ht0\relax] should work, right?
