Since you're asking for code, I'm moving this thread to the
gnucash-devel mailing list.

I tried exporting to html, and opening the result in OpenOffice. That would
allow me to do what I need, once or twice. Not particularly sustainable.
The next step would be to write an awk script to fix the html so it creates
multiple tables, and appropriate headers. Better than having to edit the
invoice in OpenOffice, but nicer not to have to run a script from the command
line.
If someone wants to point me at the code, I would consider doing it right, but
I don't know my way around the code at this point. And only if the solution
is in the C code, not the scheme, as this is not how I would choose to learn
scheme.
I know more or less all the code parts involved in generating the
invoice reports. It's mostly scheme though. The only part that's C is
the integrated webkit html renderer.
Currently, the scheme code generates the invoice as an html file. Given
GnuCash used to depend on gtkhtml for rendering the html file on screen,
the html was very basic. We have now switched to webkit, which allows
for much more advanced webfeatures (css, javascript,...), but most
reports have not seen an update to take advantage of it.
The html file is all there is. It is displayed on screen, it is sent to
the printer. It is also the basis for generating a pdf based report in
the current development versions. It's all the same unchanged base html
file.
I personally hoped to fix this by making proper use of css, but I never
had the time to dig in deeply and check if this is at all possible. I
remember I checked on webkit in this regard and I believe I eventually
got stuck on a bug in the webkit rendering engine itself. The bug was
that webkit didn't paginate properly and hence could cut lines in half
as we see now. I have not followed up since, so I don't know if the bug
is still present in more recent webkit versions.
What was your plan ? Perhaps I could help you get started.
