All of the APIs you're using are low-level things, used only for
advanced plugin frameworks or installer tools. All you need for a
simple script is:
sys.path.insert(0, abspath('egg_directory'))
import pkg_resources
pkg_resources.require('foolproof')
import foolproof
Thanks, that's much better right :)
So anyway I do have to work with plugins, specifically envisage plugins.
Moreover, our applications are normally composed by more than one egg,
and each of them has
its own setup_requires requiring a set of the global eggs.
At the moment the run system is a bit complicated and uses
pkg_resources.find_plugins...
That said reading the API was still interesting, and for example I found the
working_set.subscribe
In theory I can register a callback function that when something is
"found" does something,
and I thought immediately that it might be possible to hot-swap some
plugins at run-time,
is that true doing some tricks with that, is that correct?
def mycallback(dist):
if dist == 'name':
# reload(dist), if anything like this can be done at all
