[sage-devel] Re: spkgs dependencies graph

If you want to use it for external dependencies you'll probably need to 
know about acceptable versions of these. Then you'll soon need a sat 
solver; E.g. conda does in that way.

Cool, and then you can call Poset(digraph_spkg()).

Quick tentative, not smooth:

from sage.misc.package import *




def digraph_spkg():
"""
digraph
"""
opts = {}


local = opts.pop('local', False)
ignore_URLError = opts.pop('ignore_URLError', False)
exclude_pip = opts.pop('exclude_pip', False)
if opts:
raise ValueError("{} are not valid options".format(sorted(opts)))


installed = installed_packages(exclude_pip)


pkgs = {}


for p in os.listdir(SAGE_PKGS):
try:
f = open(os.path.join(SAGE_PKGS, p, "dependencies"))
except IOError:
# Probably an empty directory => ignore
continue


with f:
deps = f.read().splitlines()[0].strip()


if 'no dependencies' in deps:
continue
if 'not a real package' in deps:
continue

pkgs[p] = [u for u in deps.split() if u != "|" ]


return DiGraph(pkgs)
