A testing ground for Keg related code and ideas.

Project description

Keg Elements is the testing ground for ideas and code that will eventually make their way into Keg or an official Keg extension.


To develop on this project, begin by running our tests:

git clone keg-elements-src
cd keg-elements-src

You can then examine tox.ini for insights into our development process. In particular, we:

  • use py.test for testing (and coverage analysis)
  • use flake8 for linting

Preview Readme

When updating the readme, use restview --long-description to preview changes.

Pre-commit Hooks

You should install the pre-commit hooks by running

pre-commit install

This will ensure that your code is ready for review.
