From GitHub
-----------

The latest source distribution is also available in either zip_ or
tar_ format. Finally, you can also obtain the source code on GitHub
through the `PyWENO project page`_.

When using the source code from GitHub, keep in mind that PyWENO uses the
`meson-python <https://meson-python.readthedocs.io>`__ build system and requires
both ``meson`` and ``ninja`` to be available locally to build the project. For
development, an editable build is recommended::

$ pip install --no-build-isolation --editable .

To create wheels or your own source distributions, you can use::

Tracking the development repo
-----------------------------
$ python -m build --wheel
$ python -m build --sdist

Tracking the development repository
-----------------------------------

You can clone the project by running::

$ git clone git://github.com/memmett/PyWENO

Version information
-------------------

Here we obtain the version of PyWENO::
PyWENO uses standard Python packaging, so its version information can be obtained
through ``importlib``. However, you can also get it from the module itself::

>>> import pyweno.version
>>> pyweno.version.version()
>>> pyweno.version.git_version()
>>> from pyweno import __version__
>>> __version__
'0.11.2'
