What is needed for -uDNv is mostly locked away in emerge, unfortunately. |

The following couple of lines should get you everything other than --newuse |
| 8 |
though. As you only seem to be interested in what packages are available |
| 9 |
for updating, the ordering shouldn't really matter. |

import portage |
| 13 |
|
| 14 |
pdb = portage.db["/"]["porttree"].dbapi |
| 15 |
vdb = portage.db["/"]["vartree"].dbapi |
| 16 |
|
| 17 |
installed_pkgs = dict([(key, vdb.match(key)) for key in vdb.cp_all()]) |
| 18 |
latest_pkgs = dict([(key, portage.best(pdb.match(key))) for key in installed_pkgs]) |
| 19 |
updatable_pkgs = [latest_pkgs[key] for key in latest_pkgs if latest_pkgs[key] not in installed_pkgs[key]] |
| 20 |
updatable_pkgs = [pkg for pkg in updatable_pkgs if pkg] |
| 21 |
|
| 22 |
|
| 23 |
That last line there is to kill off the None elements that end up in |
| 24 |
updatable_pkgs when there is a package installed that has no versions |
| 25 |
available in the rsync tree. Other than that, portage.catpkgsplit() will |
| 26 |
split a package identifier into [cat, pkg, ver, rev]. |
