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".
I want the Lua function to be able to eat each of the first three unmarked paragraphs and optionally write some processed version back out to be typeset, but there should be the possibility that none of the paragraphs are typeset at all. In the latter case that no text is to be typeset at all, is there a way to prevent ConTeXt/LuaTeX from creating an empty PDF? \startluacode def process_paragragh (par) -- Some magic here... -- Maybe a context (processed_par) to typeset the processed paragraph... end \stopluacode \starttext Thus, I came to the conclusion that the designer of a new system must not only be the implementer and first large||scale user; the designer should also write the first user manual. \startitemize \item One \item Two \item Three \stopitemize The separation of any of these four components would have hurt \TeX\ significantly. If I had not participated fully in all these activities, literally hundreds of improvements would never have been made, because I would never have thought of them or perceived why they were important. But a system cannot be successful if it is too strongly influenced by a single person. Once the initial design is complete and fairly robust, the real test begins as people with many different viewpoints undertake their own experiments. \startmarkedparagraph Thus, I came to the conclusion that the designer of a new system must not only be the implementer and first large||scale user; the designer should also write the first user manual. \stopmarkedparagraph \stoptext Thanks, Kevin
