What callback to use,to catch all nodes in any document and how to print something in any part of document in...
0
Tell me please,what callback or callbacks better to use,to catch all nodes, which are contained in some document. Also help me please, does it really print something,for example, in the second line of the document or any other line, because tex.print prints something in the document immediately, but I want to print something in any specified place in the document?
Thanks everybody for the help.

your question is very unclear and asks about several unrelated things. You can for example use thepost_linebreak_filtercallback which will give you the nodes of each paragraph after it has been broken into lines, before they are added to the vertical list. Buttex.printacts at a completely different level returning characters from a lua string that are then tokenized by tex as if they came from an input file., tex does not track "output lines" in the document (it isn't clear what that really means) so it is hard to answer the part about "second line of a document"

@David Carlisle About post_line_break filter i tryed it and it seems,what not all nodes of document shows for me. I want to get all nodes,that lualatex find in my document. About printing i mean,for example,when i use callback process_input_buffer and analize some string of document,i want also analize previous lines and to add something not in this line,but,for example,exectly after line begin{document} or exectly before end{document}. Is it possible to do it? Thanks everybody for the help.

@AleksandrKozlovskiy Getting all nodes using callbacks is not that easy, especially since there are primitives likehpackwhich are built to circumvent callbacks. Also you have to decide of nodes introduced by the output routine (header/footer/page number/etc) should be handled too. If you need them, you can use the everyshi package to calldirectluadirectly before shipout, then just analyze the box. There are no callbacks involved then.

@AleksandrKozlovskiy there is never a time when "all nodes in the document" exist, nodes are created as needed but destroyed as each page is shipped out to the pdf back end, so you need to trap nodes as they are created in a suitable callback (or inspect the shipout box), the one i mentioned catches line breaking but would not catch vertical material that is directly added to the vertical list. you can of course detect in the input_buffer callback if the line contains the textbegin{document}but that is unrelated to node processing so it is hard to see how to answer about both

Yes,it different questions,but i have this two questions,so i desided ask this questions in one topic. But how i can print something,for example,after begin{document},if line,which i see,is not begin{document} or it's impossible in lualatex?
