## Globbing

Use "globOptions" to customise how glob patterns match files. Refer to [micromatch](https://github.com/micromatch/micromatch#options) for available options.

- basename is enabled by default, unless the pattern has a slash.
- basename is disabled depending on each pattern.
- This means the following options would work,

```yml
exclude:
  - "*foo.html" # basename is enabled
  - "**/bar/*/*.html" # basename is automatically disabled
  - "*baz.css" # basename is enabled
globOptions:
  basename: true # default
```

- This behaviour doesn't apply to pattern that starts with `!` (negation).
- This limitation only applies to `include:` option used in svg, gzip and brotli.
- This means the following options would _not_ work,

```yml
include:
  - "!foo.svg"
  - "!**/bar/*/*.svg"
globOptions:
  basename: true
```

- basename will stay disabled, if explicitly disabled in "globOptions".
