Thank you for your interest in helping to improve Odinson!

If you’re looking for a way to help, please take a look at our open issues. For those new to the project, you may want to take a look at any issues labeled good first issue.

When contributing to this repository, please first discuss the change you wish to make via issue, email, or any other method with the owners of this repository before making a change. Open communication helps us to avoid duplication of effort.

Before getting started, be sure to review our Pull request Process for a step-by-step explanation of how to get your changes reviewed and merged promptly.

Finally, please note we have a code of conduct that we expect everyone to follow throughout all interactions with the project and its community.

Pull Request Process

Before a pull request can be accepted, all automated CI checks must pass. These include unit tests, linting, and coverage tests. When adding new functionality, it is important to include tests as part of your contribution to ensure the behavior is as intended and is not lost in future updates. See our testing page for details of how to write and run unit tests.

Before opening a new pull request, ensure that …

  1. You’ve added tests for any new functionality.
  2. All tests pass locally via sbt test.
  3. Linting is performed by running sbt scalafmtAll scalafmtCheckAll.
  4. You’ve updated with a description of your contribution.

Formatting Tips

Automatic formatting is not always optimal. If you notice formatting that it is not just ugly or annoying for a particular section of code, but that significantly impedes understanding or hides errors that a different format would expose, consider these two options:

  1. Wrap the section between format comments // format: off and // format: on.
  2. Temporarily override configuration settings with scalafmt comments // scalafmt: {}.

Please consider use of these options to be recommendations. They may be ruled out during the pull request process. You may want to search for formatting comments in the code to familiarize yourself with their limited usage. Here is one particularly good example for guidance:

def fancyFormattedQuantifiers(min, max) = {
  // format: off
  case (Some(min), Some(max), _) if min > max => Fail
  case (None,      maxOption, "}")  => Pass(GreedyQuantifier(  0, maxOption))
  case (Some(min), maxOption, "}")  => Pass(GreedyQuantifier(min, maxOption))
  case (None,      maxOption, "}?") => Pass(LazyQuantifier  (  0, maxOption))
  case (Some(min), maxOption, "}?") => Pass(LazyQuantifier  (min, maxOption))
  // format: on
