Divider in grid environment

Divider in grid environment

[Jan Tosovsky]

Dear All,

I'd like to use a divider between certain paragraphs. As I want to keep all
the lines on the grid so it should have a height = N x line height.

As \hl renders the line on baseline, I have to tweek the space before/after
using the 'blank' command to keep the horizontal line in the +/- middle:

\setuplayout[grid=yes]
\showgrid
\showlayoutcomponents

\starttext
\input{ward}
\blank[4mm]\middlealigned{\hl[4]}\blank[6mm]
\input{ward}
\stoptext

But this solution requires adjustments for different fonts or font sizes...

Is there a more efficient way how to accomplish this?

Thanks, Jan

I found that \page[no] does exactly what I wanted. If needed, it breaks the
page not at the positon of a divider, but sooner, so that divider is
preceded at least with 2 lines of text.

\page[no]\blank[4mm]\middlealigned{\hl[4]}\blank[6mm]

Additionally, I'd like to keep that divider with the previous content
(paragraph).

In this case AFAIK \testpage[n] cannot be used directly in the divider
definition as it breaks the page at position of this command.

I'd like to express rather: If there is no space for three lines, break the
page, but grab few previous lines (at least 2) together with me (according
to orphan/widow settings).

The current behaviour can be demonstrated using this example:

\startsetups[grid][mypenalties]
    \setdefaultpenalties
    \setpenalties\widowpenalties{2}{10000}
    \setpenalties\clubpenalties {2}{10000}
\stopsetups

\setuplayout[grid=yes, setups=mypenalties]
\showgrid
\showlayoutcomponents

\starttext
\blank[force, 30*line]
\input{tufte}
\blank[4mm]\middlealigned{\hl[4]}\blank[6mm]
\stoptext

In my case the divider is used also to emphasise Chapter ends - so it is
very often the last element one the page and there is no need to check also
the space which follows (whether next lines will fit or not). So
'keep-with-previous' is enough for me.
