Displaying Deprecation Warnings
===============================
By default, deprecation warnings are `ignored in Python <https://docs.python.org/3/library/warnings.html#warning-categories>`_.
This also affects semver's own warnings.
It is recommended that you turn on deprecation warnings in your scripts. Use one of
the following methods:
* Use the option `-Wd <https://docs.python.org/3/using/cmdline.html#cmdoption-w>`_
to enable default warnings:
* Directly running the Python command::
$ python3 -Wd scriptname.py
* Add the option in the shebang line (something like ``#!/usr/bin/python3``)
after the command::
#!/usr/bin/python3 -Wd
* In your own scripts add a filter to ensure that *all* warnings are displayed:
.. code-block:: python
import warnings
warnings.simplefilter("default")
# Call your semver code
For further details, see the section
`Overriding the default filter <https://docs.python.org/3/library/warnings.html#overriding-the-default-filter>`_
of the Python documentation.
