Scala Project & Developer Guidelines

These guidelines are meant to be a living document that should be changed and adapted as needed. We encourage changes that make it easier to achieve our goals in an efficient way.

General Workflow

This is the process for committing code to the Scala project. There are of course exceptions to these rules, for example minor changes to comments and documentation, fixing a broken build etc.

1. Make sure you have signed the Scala CLA, if not, sign it.
2. Before starting to work on a feature or a fix, it's good practice to ensure that:
