Source Tools
============
.. currentmodule:: gpiozero.tools
GPIO Zero includes several utility routines which are intended to be used with
the :attr:`~gpiozero.SourceMixin.source` and
:attr:`~gpiozero.ValuesMixin.values` attributes common to most devices in the
library. These utility routines are in the ``tools`` module of GPIO Zero and
are typically imported as follows::
from gpiozero.tools import scaled, negated, conjunction
Given that :attr:`~gpiozero.SourceMixin.source` and
:attr:`~gpiozero.ValuesMixin.values` deal with infinite iterators, another
excellent source of utilities is the :mod:`itertools` module in the standard
library.
.. warning::
While the devices API is now considered stable and won't change in
backwards incompatible ways, the tools API is *not* yet considered stable.
It is potentially subject to change in future versions. We welcome any
comments from testers!
