Also, for a quite complex project, I need to assign different penalties
to discretionaries of the same paragraph. I've asked on [3], but it
doesn't seem possible with PdfTeX. Is there currently a way to do so in
LuaTeX (by hacking the nodes)? If not, would it be doable, like by
adding a 'penalty' field to disc nodes, with \hyphenpenalty (or any
other relevant value) assigned to it be default, but changeable?
Attached is a patch for this feature. It is very small and
non-intrusive: it basically just sets a new "penalty" field to disc
nodes, always set to 0. If the field value is 0 while line breaking, it
is ignored and the penalty associated to the disc is hyphenpenalty or
exhyphenpenalty. But if the field value is non-zero, then line breaking
uses it as the penalty associated to the disc. The value needs to be set
in a pre_linebreak_filter callback.
Attached is also a small Plain TeX example demonstrating the new feature.
It would be a huge help for me as it unlocks totally new possibilities.
What do you think?
i'll check it but as we now need to keep experimental and trunk a bit in
sync it will be end-of-month before something might show up in expermental
