Greetings!
I am interesting in writing a (small) family of reports to track
investments. One of the critical needs for what I want to do is a line
graph. I've been studying the current reporting architecture and trying
to understand it. If I understand things correctly, GnuCash has
implemented its own Scheme wrappers around Guppi, and Guppi provides the
graphing functionality. Is this correct?
I need several pointers to come up to speed:
(1) Can somebody explain (or point me to an explanation) of how Scheme
and C interact? It's pretty clear in the code that certain Scheme file
connect to certain C files, but I'm still confused on the mechanics.
(2) Is there a decent explanation on Guppi out there? The
documentation is pretty form of the include files at this point. I tried
searching for FAQ but couldn't find one. While I understand that I can
always read the source, I'm still trying to wrap my head around GnuCash,
so if there's a "this is what this call does, and here's how you use it"
document out there, I'd appreciate a link.
Thanks for any pointers!
