how to get 'module' of TypeVar ? #754
Description
Hello!
I'm currently working on py_type_extractor for getting TypeNode-ASTs at runtime (it's a py3.6+ compat-layer for codegens / runtime-type-validations / etc)
While working on the project, I couldn't get the module (or module name) of TypeVars, unlike classses/functions/etc.
Is there simply no way to get 'module' of TypeVars?
here's some code-examples to show what I'm hoping to extract from TypeVars:
- Source file
# -------- {proj_root}/packageA/packageB/some_file.py file --------
from typing import TypeVar, Generic
SomeTypeVarA = TypeVar('SomeTypeVarA')
...- Extractor
# -------- extract_typevar.py --------
from packageA.packageB.some_file import (
SomeTypeVarA
)
# how to access module (or module name) of SomeTypeVarA ?
SomeTypeVarA.__module__ # points to some python-typing internals 😭
# what I'm hoping to get:
get_module_from_typevar(SomeTypeVarA) == 'packageA.packageB.some_file'Thank you!

Sorry, there is no way.
