Hi, some time ago I asked if
\vbox{Hello world!}
could be done in Lua mode (inside \directlua{...}). I have learned that with
node.hpack() it is possible to create an \hbox{}. There is no node.vpack()
mentioned in the reference manual. Does node.vpack() exist? If yes: how can it
be used?
As I understand Taco, the \vbox{...} thing can be done from Lua. But I still
wonder how? Can I create a nodelist, invoke the line breaking algorithm and get
back a vlist?
