Appears under "Features" header, pencil subheader:
feat(pencil): add 'graphiteWidth' option
Appears under "Bug Fixes" header, graphite subheader, with a link to issue #28:
fix(graphite): stop graphite breaking when width < 0.1 Closes #28
Appears under "Performance Improvements" header, and under "Breaking Changes" with the breaking change explanation:
perf(pencil): remove graphiteWidth option BREAKING CHANGE: The graphiteWidth option has been removed. The default graphite width of 10mm is always used for performance reason.
The following commit and commit
667ecc1 do not appear in the changelog if they are under the same release. If not, the revert commit appears under the "Reverts" header.
revert: feat(pencil): add 'graphiteWidth' option This reverts commit 667ecc1654a317a13331b17617d973392f415f02.
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.
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.
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 always appear in the changelog.
Other prefixes are up to your discretion. Suggested prefixes are
test for non-changelog related tasks.
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.
A detailed explanation can be found in this document.
