Hi all,

I am wondering if and how it might be possible to catch all unmarked
paragraphs in a TeX file and pass them into Lua. So, in the following
example, each of the first three unmarked paragraphs would be passed to the
Lua function "process_paragraph" for optional processing, but the fourth
paragraph between \startmarkedparagraph...\stopmarkedparagraph would not be
passed to "process_paragraph".

If you are willing to add some more markup, then you can do

\starttext
\startMarking
...
\startmarkedparagraph
...
\stopmarkedparagraph
\stopMarking
\stoptext

where \startMarking .. \stopMarking passes everything to lua (http://wiki.contextgarden.net/Programming_in_LuaTeX#Manipulating_verbatim_text_for_dummies) and you can then search for \startmarkedparagraph ... \stopmarkedparagraph in lua.

Or you could just redefine \starttext ... \stoptext to do the capturing. Something like:

\let\normalstarttext\starttext
\let\normalstoptext\stoptext

\def\starttext{....}

And in the lua end call \normalstarttext before starting typesetting and \normalstoptext after all typesetting is done.
