Installation/Updates
####################

See the following instructions on how to install or update the package from common sources like PyPI. Developers can
also install the packages with development dependencies. In case of local development, see the additional sections on
how to run unit tests, type checks or how to build the documentation to create all the build artifacts.

See the list of :ref:`necessary dependencies <DEP>`.


.. _INSTALL/pip:

Using PIP to Install from PyPI
******************************

The following instruction are using PIP (Package Installer for Python) as a package manager and PyPI (Python Package
Index) as a source of Python packages.

PIP might download further packages as listed in :ref:`package dependencies <DEP/package>`.


.. _INSTALL/pip/install:

Installing a Wheel Package from PyPI using PIP
==============================================

Developers can install the |PackageName| package itself or the package with further dependencies for documentation
generation (``doc``), running unit tests (``test``) or just all (``all``) dependencies.

See :ref:`DEP` for more details.

.. _INSTALL/building:

Local Packaging and Installation via PIP
****************************************

For development and bug fixing it might be handy to create a local wheel package and also install it locally on the
development machine. The following instructions will create a local wheel package (``*.whl``) and then use PIP to
install it. As a user might have a |PackageName| installation from PyPI, it's recommended to uninstall any previous
|PackageName| packages. (This step is also needed if installing an updated local wheel file with same version number.
PIP will not detect a new version and thus not overwrite/reinstall the updated package contents.)

Ensure :ref:`packaging requirements <DEP/packaging>` are installed.

.. tab-set::

   .. tab-item:: Linux/macOS
      :sync: Linux

      .. code-block:: bash

         cd <pyVersioning>

         # Package the code in a wheel (*.whl)
         python3 -m build --wheel

         # Uninstall the old package
         python3 -m pip uninstall -y pyVersioning

         # Install from wheel
         python3 -m pip install ./dist/pyVersioning-0.15.0-py3-none-any.whl

   .. tab-item:: Windows
      :sync: Windows

      .. code-block:: powershell

         cd <pyVersioning>

         # Package the code in a wheel (*.whl)
         py -m build --wheel

         # Uninstall the old package
         py -m pip uninstall -y pyVersioning

         # Install from wheel
         py -m pip install .\dist\pyVersioning-0.15.0-py3-none-any.whl

.. note::

   The legacy ways of building a package using ``setup.py bdist_wheel`` and installation using ``setup.py install`` is
   not recommended anymore.
