[gentoo-portage-dev] Installed pkg list in dependency order ?

[gentoo-portage-dev] Installed pkg list in dependency order ?

[Joakim Tjernlund]

Hi 

I need to generate a pkg list from an uptodate gentoo system too feed this list into qmerge
so qmerge can install these pkgs in correct order.

Tried emerge -e but that list is not in dep order, seems to be just a list with pkgs to rebuild.

The problem with emerge -e is that is pull in the whole kitchen sink, so
all of the circular dependencies will be mixed into that order. What you
want is a smaller calculation that only updates the intended packages.

Right, but I am fresh out of ides how to do that. Any pointers?

You could try reusing the code I've written for nattka:

https://github.com/mgorny/nattka/blob/master/nattka/depgraph.py
https://github.com/mgorny/nattka/blob/master/nattka/__main__.py#L300

Note that it's a just a cheap effort, and it e.g. will order randomly
when it hits circular deps.
