SASS (@hint/parser-sass)

The SASS parser is built on top of [PostCSS][postcss] so hints can
analyze SASS and SCSS files. It emits the same events as
@hint/parser-css so existing hints targeting CSS files will work
without modification.

This package is installed automatically by webhint:

``bash
npm install hint --save-dev
`

To use it, activate it via the [.hintrc][hintrc] configuration file:

`json
{
"connector": {...},
"formatters": [...],
"hints": {
...
},
"parsers": ["sass"],
...
}
`

Note: The recommended way of running webhint is as a devDependency of
your project.

Events emitted

This parser emits the following events:

* parse::start::css of type Event which contains the following information:

* resource: the resource we are going to parse.

* parse::end::css of type StyleParse which has the following information:

* ast: a PostCSS Root object containing the AST.
See the [PostCSS walk* APIs][postcss-walk] for help navigating
the AST.
* code: a string containing the raw stylesheet source code.
* element: an HTMLElement reference if the source was inline
in HTML; null otherwise.
* resource: the parsed resource. If the CSS is in a style tag
and not a file, the value will refer to the HTML document containing
the stylesheet.

Limitations

This parser is not fault-tolerant (unlike @hint/parser-css`) so only
well-formed files will be parsed.
