Thanks, Taco!
than this question is to Hans. ;-)
another example with a table:
\documentclass{article}
\usepackage{lua}
\begin{document}
\section{Example}
\begin{table}
\tabcolsep=0pc
\caption{My table}
\begin{tabular*}{\columnwidt...@{\extracolsep{\fill}}llllll@{}}
\hline
Coll1 & \multicolumn{5...@{}}{coll2} \\
\hline
& B0 & A0 & G0 & K0 & WD \\
\hline
V & 20 & 19.8 & 19.7 & 19.7 & 19.7 \\
\hline
\end{tabular*}
\end{table}
$2+2-E(R) = n$
\end{document}
if I use pre_output_filter, I don't see table :(
output 1 node.count=6 attr=nil <-- section seen here
output 2 node.count=2 attr=nil
output 3 node.count=12 attr=nil <-- section and formula seen here
output 4 node.count=3 attr=nil
output 5 node.count=4 attr=nil
question: how to see all the nodes using callback in a shipout mode?
or how to find out which hlist/vlist will be outputted?
thanks in advance :)

Hi, lua experts!!
I'm running a simple vpack_filter callback on a simple example:
\documentclass{article}
\usepackage{lua} %<--there is my callback
\begin{document}
$2+2-E(R) = n$
\end{document}
i see, that the formula is traversed in 1,3,4 vbox:
vbox 1 node.count=6 attr=nil <--here
vbox 2 node.count=2 attr=nil
vbox 3 node.count=6 attr=nil <--here
vbox 4 node.count=2 attr=nil <--here
split_keep 5 node.count=2 attr=nil
split_off 6 node.count=1 attr=nil
vbox 7 node.count=4 attr=nil
Question is: how to know which one is shipout mode or is there something
like checking \ifvmode, useing vpack_filter???
Probably Hans knows these extra packtypes better than I do by now, but
the shipout packaging has a dedicated callback: pre_output_filter.
Best wishes,
Taco
