Most people know about pep8 which enforce coding style. pyflakes goes a step beyond by analyzing the code. flake8 is basically a wrapper around both pep8 and pyflakes and comes with some additional checks. I find it very useful since you only need to require one package to have a lot of code issues reported to you. This patch provides a 'flake8' tox environement to easily install and run the utility on the code base. One simply has to: tox -eflake8 The env has been added to the default list of environement to have flake8 run by default. Configuration tweaking is done in setup.cfg [flake8] section. The repository in its current state does not pass checks We can later easily ensure there is no regression by adjusting Travis configuration to run this env.
