How to Contribute¶
Contributions to Ratel are encouraged.
Please make your commits well-organized and atomic, using git rebase --interactive as needed.
Check that all tests pass using make prove or make junit.
If adding a new feature, please add or extend a test so that your new feature is tested.
In typical development, every commit should compile, be covered by the test suite, and pass all tests.
This improves the efficiency of reviewing and facilitates use of git bisect.
Open an issue or RFC (request for comments) pull request to discuss any significant changes before investing time. It is useful to create a WIP (work in progress) pull request for any long-running development so that others can be aware of your work and help to avoid creating merge conflicts.
Write commit messages for a reviewer of your pull request and for a future developer (maybe you) that bisects and finds that a bug was introduced in your commit. The assumptions that are clear in your mind while committing are likely not in the mind of whomever (possibly you) needs to understand it in the future.
Give credit where credit is due using tags such as Reported-by: Helpful User <helpful@example.com> or Co-authored-by: Snippet Mentor <code.by@comment.com>.
Please use a real name and email for your author information (git config user.name and user.email).
If your author information or email becomes inconsistent (look at git shortlog -se), please edit .mailmap to obtain your preferred name and email address.
When contributors make a major contribution and support it, their names are included in the automatically generated user-manual documentation.
Please avoid “merging from upstream” (like merging ‘main’ into your feature branch) unless there is a specific reason to do so, in which case you should explain why in the merge commit. Rationale from Junio and Linus.
You can use make format to help conform to coding conventions of the project, but try to avoid mixing whitespace or formatting changes with content changes (see atomicity above).
By submitting a pull request, you are affirming the following.
