Get python3 package metadata given source directory without installing

I am trying to get some package metadata (name, version) given a path to the source directory without installing said package.

These work, using setup.py if you're sitting in the root directory:

> python3 setup.py --name
my_package_name

> python3 setup.py --version
0.1.0

However, I have been cautioned away from using python3 setup.py commands -- and indeed see a warning:

.../lib/python3.7/site-packages/setuptools/installer.py:30: SetuptoolsDeprecationWarning: setuptools.installer is deprecated. Requirements should be satisfied by a PEP 517 installer.
  SetuptoolsDeprecationWarning,

I know pip show my_package_name will print various metadata about a package (including name/version), however it requires that the package is installed into the environment. It also doesn't take a source directory and thus requires I already know the name of the package I want the info on.

> pip show .
WARNING: Package(s) not found: .

> pip show my_package_name
WARNING: Package(s) not found: my_package_name

> pip install .
...

> pip show my_package_name
Name: my_package_name
Version: 0.1.0
...
...

Is there any equivalent pip command (or other tool) that will show me the version of a package given the source directory without actually installing the package?

Thanks in advance!
