I recently started experimenting with using ConTeXt (mkiv) for dictionary
typesetting. It's a much
more attractive option than plain TeX or LaTeX because of the support for
typesetting on a grid.
However, grid typesetting can easily result in a large number of orphans and
widows, which really
doesn't look good in a dictionary.
In an ideal world, I'd want to alter the column width slightly to prevent them
(because most
dictionaries aren't justified, this wouldn't be very noticeable).
Would it be possible to use LuaTeX to achieve this? I.e., could one write some
code that gets
triggered by orphans and widows and then alters the current column width
slightly until the
problem disappears? Has somebody already done this? Or have the relevant TeX
internals not been
Luafied yet?
I'd also be interested in other ways to solve this issue – for instance
changing the looseness
dynamically instead of the column width.
Have a look at \widowpenalty and \clubpenalty. Also use margin kerning and
font expansion.
\widowpenalty and \clubpenalty are almost useless in this context –
believe me, I've tried! (I'm typesetting on a grid, with a fixed
number of lines per page.) Which is why I'm looking for alternatives.
Margin kerning and font expansion are definitely options, but again,
my real query would be how to trigger them dynamically to avoid a
widow or an orphan.
can you make a small example showing the problem
