Hi Alec,
the examples given doesn’t work. Maybe you’re missing something.
env should be imported from fabric.api, if not, Python fails with NameError:
name 'env' is not defined
Also, the Python path should include foo/and can/, so you need to call a
python executable from the project root (Or add ROOT_DIRECTORY to the
python path with sys.path.append(ROOT_DIRECTORY)). For example:
## foo/__init__.py
import sys
import os
sys.path.append(os.path.abspath('.'))
from fabric.api import execute
from can.haz import funtimes
domain = 'localhost'
env.user = 'bar'
env.password = 'foo'
env.hosts = [domain]
execute(funtimes)
And you execute it with: python foo/__init__.py. And this works.
Regards
