Hi there,
I need to get a list of eggs in 'dependency' order: a list with eggs (Distribution objects?) which is sorted so that earlier entries will never depend on entries later in the list. [1]
I spotted the _dep_map attribute on Distribution objects and it seems to have something like that already.
Exactly what is in _dep_map? Could I use it to compute what I need?
No. Use the .requires() method of a distribution instead, to get its immediate requirements, and then you'll need to do your own sort. Please see http://peak.telecommunity.com/DevCenter/PkgResources for the full pkg_resources API. There's no need for you to mess with private attributes for this stuff.
[1] In fact, this is an intermediary result - I want to compute all the entry points of a tree of dependencies in such a way that the entry points of eggs deeper in the tree will always be earlier in the list than entry points for those shallower in the tree.
Why?
