- **condition**: `type` is found in value
- **rule**: `always`
- **value**

  ```
  [
    'build',
    'ci',
    'docs',
    'feat',
    'fix',
    'perf',
    'refactor',
    'revert',
    'style',
    'test'

```

echo "FIX: some message" # fails
echo "fix: some message" # passes
```

#### type-empty

- **rule**: `never`

```sh
echo ": some message" # fails
echo "fix: some message" # passes
```

- **rule**: `never`

```sh
echo "fix(SCOPE): Some message" # fails
echo "fix(SCOPE): Some Message" # fails
echo "fix(SCOPE): SomeMessage" # fails

The [angular commit
convention](hhttps://github.com/angular/angular/blob/main/CONTRIBUTING.md#commit)
does not use a `!` to define a breaking change in the commit subject. If you
want to use this feature please consider using the [conventional commit
config](https://github.com/conventional-changelog/commitlint/tree/master/%40commitlint/config-conventional#commitlintconfig-conventional).

#### header-max-length

- **condition**: `header` has `value` or less characters
- **rule**: `always`
- **value**

```
72
```

```sh
echo "fix: some message that is way too long and breaks the line max-length by several characters" # fails
echo "fix: some message" # passes
```

### Warnings
