LESS (@hint/parser-less)

The LESS parser is built on top of PostCSS and postcss-less so hints can analyze LESS 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:

npm install hint --save-dev

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

{
    "connector": {...},
    "formatters": [...],
    "hints": {
        ...
    },
    "parsers": ["less"],
    ...
}

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 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.
