Introduction
============

hacking is a set of flake8 plugins that test and enforce the `OpenStack
Style Guidlines <http://docs.openstack.org/developer/hacking>`_.

Installation
============

hacking is available from pypi, so just run:

``pip install hacking``

This will install ``flake8`` with the ``hacking`` and ``pyflake`` plugins

Origin
======

Most of the additional style guidelines that OpenStack has taken on came from
the Google Python Style Guide.

- http://google-styleguide.googlecode.com/svn/trunk/pyguide.html

Since then, a few more OpenStack specific ones have been added or modified.

Versioning
==========

hacking uses the major.minor.maintenance release notation, where maintenance
releases cannot contain new checks. This way projects can gate on hacking
by pinning on the major.minor number while accepting maintenance updates
without being concerned that a new version will break the gate with a new
check.

Adding additional checks
========================

Each check is a pep8 plugin so read

- https://github.com/jcrocholl/pep8/blob/master/docs/developer.rst#contribute

The focus of new or changed rules should be to do one of the following

- Substantially increase the reviewability of the code (eg: H301,2,3
as they make it easy to understand where symbols come from)
- Catch a common programming error that may arrise in the future (H201)
- Prevent a situation that would 100% of the time be -1ed by
developers (H903)

But, as always, remember that these are Guidelines. Treat them assuch. There are always times for exceptions. All new rules shouldsupport noqa.
