Git Commit Message Guidelines
最后更新于
这有帮助吗？
We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages to generate the Angular change log.
Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:
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.
The footer should contain a if any.
Samples: (even more )
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:
build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
docs: Documentation only changes
feat: A new feature
fix: A bug fix
perf: A code change that improves performance
refactor: A code change that neither fixes a bug nor adds a feature
style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
test: Adding missing tests or correcting existing tests
The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages.
The following is the list of supported scopes:
animations
common
compiler
compiler-cli
core
elements
forms
http
language-service
platform-browser
platform-browser-dynamic
platform-server
platform-webworker
platform-webworker-dynamic
router
service-worker
upgrade
There are currently a few exceptions to the "use package name" rule:
packaging: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
changelog: used for updating the release notes in CHANGELOG.md
aio: used for docs-app (angular.io) related changes within the /aio directory of the repo
none/empty string: useful for style, test and refactor changes that are done across all packages (e.g. style: add missing semicolons)
The subject contains a succinct description of the change:
use the imperative, present tense: "change" not "changed" nor "changes"
don't capitalize the 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.
