Code Review Contributions


Code Review Contributions

In addition to bug fixing, you can help us review waiting pull requests. This is also a good (and recommended) way to get to know the feel of the bug-fixing and submissions process before jumping in with your own pull requests.

Review Guidelines

Code of Conduct reminder

  • Keep comments on-topic, concise and precise.
  • Attach comments to particular lines or regions they pertain to whenever possible.
  • Short code examples are often more descriptive than prose.
  • If you have thoroughly reviewed the PR and thought through all angles, LGTM (Looks Good To Me) is the preferred acceptance response.
  • Additional reviews should try to offer additional insights: “I also thought about it from this angle, and it still looks good..”
  • Above all, remember that the people you are reviewing might be reviewing your PRs one day too.
  • If you are receiving the review, consider that the advice is being given to make you, and Scala, better rather than as a negative critique. Assume the best, rather than the worst.
