cycle not detected #23
Description
A rather primitive module cycle is not detected. Minimal working example:
reproduction
├── __init__.py
├── moduleA
│ ├── __init__.py
│ └── a_class.py
└── moduleB
├── __init__.py
└── b_class.py
reproduction > moduleA > __init__.py:
from .a_class import ClassAreproduction > moduleA > a_class.py:
import reproduction.moduleB
class ClassA:
passreproduction > moduleB > __init__.py:
from .b_class import ClassBreproduction > moduleB > b_class.py:
from ..moduleA import ClassA
class ClassB:
passWhen running pycycle:
> pycycle --here --verbose

Project successfully transformed to AST, checking imports for cycles..
No worries, no cycles here!
If you think some cycle was missed, please open an Issue on Github.
