Want to contribute? Great! First, read this page (including the small print at the end).
Before we can use your code, you must sign the Google Individual Contributor License Agreement (CLA), which you can do online. The CLA is necessary mainly because you own the copyright to your changes, even after your contribution becomes part of our codebase, so we need your permission to use and distribute your code. We also need to be sure of various other things—for instance that you'll tell us if you know that your code infringes on other people's patents. You don't have to sign the CLA until after you've submitted your code for review and a member has approved it, but you must do it before we can put your code into our codebase.
Before you start working on a larger contribution, you should get in touch with us first through the issue tracker with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on.
All submissions, including submissions by project members, require review. We recommend forking the repository, making changes in your fork, and sending us a pull request so we can review the changes and merge them into this repository.
Functional changes will require tests to be added or changed. The tests live in
the test/ directory, and are run with pub run test. If you need to create
new tests, use the existing tests as a guideline for what they should look like.
Before you send your pull request, make sure all the tests pass!
