[gentoo-portage-dev] accessing portage updates through it's data structures

[Tom Hosiawa]

I'm writing a superkaramba theme for showing the current available
updates on a system (www.tomek.ca for an example), but I'm having
trouble parsing the list into seperate properties for each ebuild
(package name, version, use flag).

Right now, I'm trying get the ebuild information through parsing the
output of emerge with regular expressions in python. But I'm running
into problems when a package doesn't have any use flags and when a
package name has a hypen in it.

I'm wondering if it's possible, to somehow call emerge from within my
superkaramba python program and get all the details of each ebuild
from the portage data structures directly? I'm thinking this might be
a little easier than trying to figure out the perfect regular
expression to handle all the different formats possible, but I'm not
familiar enough with python/portage to know how to do this.

Anybody have any ideas how I can basically do 'emerge -puDNv' directly
from my superkaramba python program, and get the updates available
directly from the portage data structures?
