I am trying to implement RTF export of headers/footers. It seems to me
that in general the internal representation of header/footers is not
optimal. As far as I can tell, the pt_PieceTable holds a single dividing
line in the form of a pf_Frag that delineates headers/footers from the main
text.
The problem arises when I need to know when the header/footer has
ended. In short, I don't. I never recieve notification in the exporter
that the header has finished. The exporter is left hanging in a way that it
cannot close the document (clean up the stack of braces for RTF).
In my case, the document looks like:
Section | Block | Text | Text | Block | Text | Header | Block |Text | Block
| Text
I think it would be better if the document was structured as a recursive
set of containers as in
PieceTable
|-Section --- Block---Text
| | |-Text
| |- Block---Text
|-Header--- Block---Text
|- Block---Text
This would allow things like putting a different header in each section,
and handling outline levels of a document, as well as trivializing the
problem of knowing when the emission of a document portion has ended.
Does anyone know what this change would involve?
