Each commit message consists of a header, a body and a footer. The header has a special format that includes a type and a subject:
<type>: <subject> <body> <BLANK LINE> <footer>
If the commit reverts a previous commit, it should begin with
revert:, followed by the header of the reverted commit. In the body it should say:
This reverts commit <hash>., where the hash is the SHA of the commit being reverted.
Must be one of the following:
- feat: A new feature
- fix: A bug fix
- docs: Documentation only changes
- style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
- refactor: A code change that neither fixes a bug nor adds a feature
- perf: A code change that improves performance
- test: Adding missing tests
- chore: Changes to the build process or auxiliary tools and libraries such as documentation generation
The subject contains succinct description of the change:
- use the imperative, present tense: "change" not "changed" nor "changes"
- don't capitalize first letter
- no dot (.) at the end
Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.
The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.
Breaking Changes should start with the word
BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.
