Support of "package_dir" from setup.py

[dmitry-lipetsk]

Hello.

I am trying to use Sphinx in project where source code lives in "src" folder and setup.py has declaration package_dir = {"mypackage": "src"}

project folder
|---doc
|---src
|     |--- apy.py
|     |     ...
|...
|--- setup.py
|...

Sphinx conf.py has the the code to correct sys.path:

sys.path.insert(0, "path_to_project_folder")

When my rst-file contains:

mypackage.api
------------

.. automodule:: mypackage.api
    :members:
    :undoc-members:
    :show-inheritance:

Sphinx can't find mypackage.api module.

When my rst-file contains:

mypackage.api
------------

.. automodule:: src.api
    :members:
    :undoc-members:
    :show-inheritance:

it works, but I get the documentation that describes "src.api" but not "mypackage.api".

Does Sphinx has a support for the such project structures?

Thanks.
