Hi Georg, Laurent,
Yesterday evening I had a look at the FOP code with your other
proposal about Knuth Sequence in mind. Well, that's too hard
for me yet and I'll take the "easy" (hum) way for the moment.
I don't understand the theory behind it either but if I'm not
mistaken, you can look at the sequence of KnuthElements as just a
chain of small text areas separated by spaces (=penalties) and break-
possibilities. But before I make a complete fool out of myself, I
better leave that topics to the experts.
Basically not bad as an interpretation, although KnuthElements are
generated that represent border, padding etc. rather than merely 'text
fragments'. And OTOH, penalties actually do not correspond to spaces.
Penalties represent break-possibilities (or -impossibilities if
penalty=INFINITE). Spaces, in the most common case, correspond to
KnuthGlue objects, which are a break-possibility only if they are
preceded by a KnuthBox. In many cases, FOP generates a sequence of
penalty-box-glue for a space (to avoid a break before, or to hint at
what happens if there is a break before --i.e. how much width should
be added to the line when choosing that possibility as an effective
break)
