Development

Getting Started

Assuming you have Python 3.6 and pipenv installed. Create a new virtual environment:

$ pipenv sync --dev

Running Tests

Running unit tests:

$ pytest ./sosw/test/suite_3_6_unit.py

Contribution Guidelines

Release cycle

• We follow both Semantic Versioning pattern and PEP440 recommendations where comply
• Master branch commits (merges) are automatically packaged and published to PyPI.
• Branches for planned staging versions follow the pattern: X_Y_Z (Major.Minor.Micro)
• Make your pull requests to the latest staging branch (with highest number)
• Latest documentation is compiled from branch docme. It should be up to date with latest staging branch, not the master. Make PRs with documentation change directly to docme.

Code formatting

Follow PEP8, but:

• both classes and functions are padded with 2 empty lines
• dictionaries are value-alligned

Initialization

1. Fork the repository: https://github.com/bimpression/sosw
2. Register Account in AWS: SignUp
3. Run pipenv sync –dev to setup your virtual environment and download the required dependencies
4. Create DynamoDB Tables:
   • You can find the CloudFormation template for the databases in the example.
   • If you are not familiar with CloudFormation, we highly recommend at least learning the basics from the tutorial.
5. Create Sandbox Lambda with Scheduler
6. Play with it.
7. Read the Documentation Convention.

Building the docs

Sphinx is used for building documentation. To build HTML documentation locally, use:

$ sphinx-build -ab html ./docs ./sosw-rtd

You can then use the built in Python web server to view the html version directly from localhost in your preferred browser.

$ cd sosw-rtd
$ python -m http.server
