Developer Guide

Before trying to run tools/cryptux locally, make sure it uses local libraries by running:

python setup.py develop

It's highly recommended that you use the package virtualenvwrapper.

To test the changes without publishing to PyPI, force pip to install from local dir:

pip install -e /path/to/cryptux

Publishing to test PyPI can be done via this command:

python setup.py sdist upload -r testpypi

Use flake8 to detect PEP8 violations and format code nicely using yapf -i, do check the project YAPF.

Bitcoin
