When it comes to commit messages, we all have witnessed the worst of our kind: while code is (hopefully) carefully crafted, the urge to submit our work for peer review can play badly with the helpfulness of the commit message attached (leaving a helpless reviewer in the dark and calling for the developer presence to explain the meaning of the coded feature). Machine translation techniques come to the rescue, by providing a viable aid to suggesting better commit messages from a golden standard of various situations: by analyzing thousands of commit messages along with their patches, we show that a machine can understand the semantics of a patch thus providing a way to automatically tell good messages from bad messages. We can employ this in CI environments to rule out insufficiently documented patches or to propose better alternatives to the developers.
