## Git Commit Message Convention
> This is adapted from [Angular's commit convention](https://github.com/conventional-changelog/conventional-changelog/blob/master/packages/conventional-changelog-angular/convention.md).
#### Examples
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
close #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.
```
### 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 place of the commit change. For example `core`, `compiler`, `ssr`, `v-model`, `transition` etc...
### Subject
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
### 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.
