Commit Message Format
A commit message consists of a header, body and footer. The header has a type, scope and subject:
<type>(<scope>): <subject> <BLANK LINE> <body> <BLANK LINE> <footer>
The header is mandatory and the scope of the header is optional.
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.
If the prefix is
perf, it will appear in the changelog. However if there is any BREAKING CHANGE, the commit will always appear in the changelog.
Other prefixes are up to your discretion. Suggested prefixes are
test for non-changelog related tasks.
Details regarding these types can be found in the official Angular Contributing Guidelines.
The scope could be anything specifying place of the commit change. For example
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.
