Dear all,

I’m finishing a book, and getting the following undesired result.
Many times I have section or subsection title at the bottom of a page, 
with no text. Text starts on the next page.

I have looked at

http://wiki.contextgarden.net/Widows_and_orphans_control

but I wasn’t able to solve.

I guess it could depend on the formatting of my headlines. Here they are:

\setuphead[section]
[style=\ss\tfa, 
before={\blank[0.5cm]\startframedtext[offset=0.25cm,framecolor=black,
rulethickness=0.01cm, frame=off, topframe=off, 
 bottomframe=on]\crlf},after={\stopframedtext\noindentation\blank[1cm]}]


\setuphead[subsection]
[style=\ss, 
before={\blank[0.5cm]\startframedtext[offset=0.25cm,framecolor=black,
rulethickness=0.01cm, frame=off, topframe=off, 
 bottomframe=on]\crlf},after={\stopframedtext\noindentation\blank[1cm]}]

Your lack of a working minimal example makes it hard to give a solution
but adding changing the way how the frame is added should improve things.

\startsetups[section:andrea]
\ifconditional\headshownumber
\scratchdimenone\dimexpr\headnumberwidth+\headnumberdistance\relax
\scratchdimentwo\dimexpr\headnumberdistance\relax
\else
\scratchdimenone\zeropoint
\scratchdimentwo\zeropoint
\fi

\startframedtext[offset=0.25cm,loffset=\scratchdimenone,rulethickness=0.01cm,frame=off,bottomframe=on]

\dontleavehmode\llap{\headnumbercontent\hskip\scratchdimentwo}
\headtextcontent
\stopframedtext
\stopsetups

\defineheadalternative[section:andrea][alternative=vertical,renderingsetup=section:andrea]

\setuphead
  [section]
  [alternative=section:andrea,
   numberwidth=1em,
before={\blank[0.5cm]},
 after={\blank[1cm]}]

\starttext

\section{\input ward }

\subject{\input ward }

\stoptext

In a much simpler case, it seems to work:

\setuphead[section]
[style=\ss\tfa, after={\hrule\blank[samepage,big]}]
%~ [style=\ss\tfa, after={\hrule\blank[big]}]

\setuphead[subsection]
[style=\ss, after={\hrule\blank[samepage,medium]}]
%~ [style=\ss, after={\hrule\blank[medium]}]

\starttext
\dorecurse{10}{\section{Section}
\input knuth
\subsection{Subsection}
\input zapf}
\stoptext

Do you really need headings to be inside framed texts?

I'm sorry, compose=yes works as expected (I was copy pasting some old
code and forgot about the later improvements in ConTeXt: shame on me).

But the code above doesn't seem to work (I don't get the letter "č"
printed out at all). I would prefer the approach with more fine-tuning
though because "č" is always misaligned. And I seem to remember that
this functionality has been in the core for a long time already, I
just again forgot about it because most fonts include the full charset
nowadays.

When has \shiftup been implemented?

It doesn't work in TeX Live (or maybe I forgot to update TL to the
latest version), but works with the latest version of ConTeXt.


it has always been there but recently i saw that when i had updated some

Nevertheless this doesn't entirely solve the problem. I now have a
problem with the following:

\catcode`č=\active

I will try to remember how to fix the font on the fly with lua (or
perhaps figure out how to edit the font; it's a commercial font
though, so fixing it "on the fly" would probably be better).

I will also test some other piece of code that Hans sent me off-list.
(I seem to remember that there must be some tens of ways to underline
text. Every now and then Hans sends a new demo.)


so let's give you another piece

Hi Andrea,

you may replace \blank[1cm] with \blank[samepage,1cm].

This should move the heading to the next page.

Just in case it helps,

Pablo

Instead of creating an active character, does this work:

  [compose=yes]

The git history first mentions it on 2015.12.22. I didn't know that
command, either.

When has \shiftup been implemented?

It doesn't work in TeX Live (or maybe I forgot to update TL to the
latest version), but works with the latest version of ConTeXt.

Nevertheless this doesn't entirely solve the problem. I now have a
problem with the following:

\catcode`č=\active
\defč{\buildtextaccent\textcaron c}

\underbar{Test this č}

I will try to remember how to fix the font on the fly with lua (or
perhaps figure out how to edit the font; it's a commercial font
