no-implicit-reexport resolves implicit re-exports as Any #12749
Description
# foo.py
class Foo:
...# bar.py
from foo import Foo# baz.py
from bar import Foo # Module "bar" does not explicitly export attribute "Foo"; implicit reexport disabled [attr-defined]
reveal_type(Foo) # Revealed type is "Any"mypy should still resolve the import like it does when no-implicit-reexport is disabled.
in my case, i'm trying to use a library that imports its own classes using implicit re-exports, which results in pretty much everything being treated as Any in my project

As a workaround you could apply an override to the mypy config:

Just to be clear - are you expecting mypy to give the error (
... does not explicitly export attribute ...) but then still treat it as being exported?Also, in your examples the files are all .py files - are there stubs for the external libraries? If so, can you change the stubs to have explicit re-exports?

yes
the library i'm using has types defined in its
.pyfiles, but i'm pretty sure it would behave the same if they were stubs. i also can't really fix them without making stubs for the entire thing which would be a waste of time because they're already typedPreserve (some) implicitly exported types (#13967)

using
__all__ = ["Foo"]mypy will know about it.
