## Git Commit Message Convention
|
|
|
|
> This is adapted from [Angular's commit convention](https://github.com/conventional-changelog/conventional-changelog/tree/master/packages/conventional-changelog-angular).
|
|
|
|
#### TL;DR:
|
|
|
|
Messages must be matched by the following regex:
|
|
|
|
```js
|
|
/^(revert: )?(feat|fix|docs|style|refactor|perf|test|workflow|build|ci|chore|types|wip): .{1,50}/;
|
|
```
|
|
|
|
#### Examples
|
|
|
|
Appears under "Features" header, `dev` subheader:
|
|
|
|
```
|
|
feat(dev): add 'comments' option
|
|
```
|
|
|
|
Appears under "Bug Fixes" header, `dev` subheader, with a link to issue #28:
|
|
|
|
```
|
|
fix(dev): fix dev error
|
|
|
|
close #28
|
|
```
|
|
|
|
Appears under "Performance Improvements" header, and under "Breaking Changes" with the breaking change explanation:
|
|
|
|
```
|
|
perf(build): remove 'foo' option
|
|
|
|
BREAKING CHANGE: The 'foo' option has been removed.
|
|
```
|
|
|
|
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(compiler): add 'comments' option
|
|
|
|
This reverts commit 667ecc1654a317a13331b17617d973392f415f02.
|
|
```
|
|
|
|
### Full 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.
|
|
|
|
### Revert
|
|
|
|
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.
|
|
|
|
### Type
|
|
|
|
If the prefix is `feat`, `fix` or `perf`, it will appear in the changelog. However, if there is any [BREAKING CHANGE](#footer), the commit will always appear in the changelog.
|
|
|
|
Other prefixes are up to your discretion. Suggested prefixes are `docs`, `chore`, `style`, `refactor`, and `test` for non-changelog related tasks.
|
|
|
|
### Scope
|
|
|
|
The scope could be anything specifying the place of the commit change. For example `dev`, `build`, `workflow`, `cli` etc...
|
|
|
|
### Subject
|
|
|
|
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
|
|
|
|
### Body
|
|
|
|
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.
|
|
|
|
### Footer
|
|
|
|
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.
