"""Set lib version from `pyproject.toml`.

.. note::

  .. deprecated:: 1.3.6
    Use:

    .. code-block:: python
  
      __version__ = __import__("importlib.metadata", fromlist=["version"]).version(
          <package name>
      )
  
    instead 

This library allows for setting the version number for a library from
the pyproject.toml file.

Add to your `pyproject.toml` add a new section:

.. code-block:: toml

  [tool.berhoel.helper.set_version]
  version_files = ["berhoel/helper/_version.py"]

Generate the version file:

.. code-block:: shell

  > poetry run set_lib_version
  writing berhoel/helper/_version.py

In the library `__init__.py` just use:

.. code-block:: python

  try:
      from ._version import __version__
  except ImportError:
      __version__ = "0.0.0.invalid0"
