Dear list,
Sometimes I want to break out into Lua during typesetting and just
inspect the last node at the current point. LuaTeX gives me the
opportunity to get the last node using node.last_node(). However this
pops the node from the list, i.e. it disappears from the output stream.
I don't want this. I simply want to inspect the node and maybe insert
something in the current list. I'm not even able to reinsert the node
because node.write(node.copy(last)) confuses the parbuilder. Also, how
can I get the current list? MWE below.
Cheers, Henri

\directlua{
local last = node.last_node()
node.write(node.copy(last))
