I'd need a way to get the LaTeX export of a text segment, generally from a DocIterator to another. Looking at the code, the single paragraph seems the finest granularity at which LaTeX export may be done easily, through the lyx::TeXOnePar() function.
Yes. ViewSource exports paragraphs.
Also, I'd like to know if there is any function that, given a position on the LaTeX export, provides the DocIterator (almost) equivalent position in the Buffer. Guess I could exploit this TexRow stuff for this purpose, but I'd need some hand-written logics to finish the work inside the single-line granularity.
There was a patch from Alfredo a while ago that tries to highlight lines in ViewSource window, search "linking source view with text" for the patch. It handles TexTow stuff. Bo
