If the behavior is an egregious violation, the community member who +committed the violation may be banned immediately, without warning. +3. Otherwise, moderators will first respond to such behavior with a warning. +4. Moderators follow a soft "three strikes" policy - the community member may +be given another chance, if they are receptive to the warning and change their +behavior. +5. If the community member is unreceptive or unreasonable when warned by a +moderator, or the warning goes unheeded, they may be banned for a first or +second offense.

First, +install dependencies (feel free to reuse the virtual environment from above): + +.. code-block:: shell + + python3 -m venv .env + source .env/bin/activate + pip install Sphinx sphinx-rtd-theme + +Now, once you have the virtual environment activated: + +.. code-block:: shell + + cd docs + sphinx-build -E -W -b html . _build/html + +This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to +view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to +locally verify it will pass. diff --git a/adafruit_aws_iot.py b/adafruit_aws_iot.py new file mode 100644 index 0000000..8ff5e66 --- /dev/null +++ b/adafruit_aws_iot.py @@ -0,0 +1,252 @@ +# The MIT License (MIT) +# +# Copyright (c) 2019 Brent Rubell for Adafruit Industries +# +# Permission is hereby granted, free of charge, to any person obtaining a copy +# of this software and associated documentation files (the "Software"), to deal +# in the Software without restriction, including without limitation the rights +# to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +# copies of the Software, and to permit persons to whom the Software is +# furnished to do so, subject to the following conditions: +# +# The above copyright notice and this permission notice shall be included in +# all copies or substantial portions of the Software. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +# FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
