hallo, Hans!
I'm interested in "page_insert (id 41)" node. It's just mentioned in
node list, but not documented (in luatexref-t.pdf (beta 0.62.0)).
Is there a chance to break a page (or create a page breaking node) while
traversing the nodes.
Maybe "page_insert" does that?
no, nodes like that are mentioned in the manual (side effect of the fact
that the list is auto generated) but not really public ... they are used
in tex itself when breaking paragraphs and pages .. so they are not
documented because they are not meant to be used
actually there are a couple of more nodes that you can create and push
in the list but even then tex has some assumptions about what node to
expect where so it might give unwanted side effects
the page builder is not opened up yet (the parbuilder is partially
opened up) so much of that might change before luatex 1.0
concerning breaking a page: you can insert a penalty node with a high
value (i.e. do at the lua end what normally happens at the tex end)
(btw, 'insert' normally refers to insert nodes)
