  help: "\n    Usage: stylelint [input] [options]\n\n    Input: Files(s), glob(s), or nothing to use stdin.\n\n      If an input argument is wrapped in quotation marks, it will be passed to\n      node-glob for cross-platform glob support. node_modules and\n      bower_components are always ignored. You can also pass no input and use\n      stdin, instead.\n\n    Options:\n\n      --config\n\n        Path to a specific configuration file (JSON, YAML, or CommonJS), or the\n        name of a module in node_modules that points to one. If no --config\n        argument is provided, stylelint will search for configuration files in\n        the following places, in this order:\n          - a stylelint property in package.json\n          - a .stylelintrc file (with or without filename extension:\n            .json, .yaml, and .js are available)\n          - a stylelint.config.js file exporting a JS object\n        The search will begin in the working directory and move up the directory\n        tree until a configuration file is found.\n\n      --config-basedir\n\n        An absolute path to the directory that relative paths defining \"extends\"\n        and \"plugins\" are *relative to*. Only necessary if these values are\n        relative paths.\n\n      --ignore-path, -i\n\n        Path to a file containing patterns that describe files to ignore. The\n        path can be absolute or relative to process.cwd(). By default, stylelint\n        looks for .stylelintignore in process.cwd().\n\n      --syntax, -s\n\n        Specify a non-standard syntax. Options: \"scss\", \"less\", \"sugarss\".\n        If you do not specify a syntax, non-standard syntaxes will be\n        automatically inferred by the file extensions .scss, .less, and .sss.\n\n      --stdin-filename\n\n        A filename to assign stdin input.\n\n      --ignore-disables, --id\n\n        Ignore styleline-disable comments.\n\n      --formatter, -f               [default: \"string\"]\n\n        The output formatter: \"json\", \"string\" or \"verbose\".\n\n      --custom-formatter\n\n        Path to a JS file exporting a custom formatting function.\n\n      --quiet, -q\n\n        Only register warnings for rules with an \"error\"-level severity (ignore\n        \"warning\"-level).\n\n      --color\n      --no-color\n\n        Force enabling/disabling of color.\n\n      --report-needless-disables, --rd\n\n        Report stylelint-disable comments that are not blocking a lint warning.\n        If you provide the argument \"error\", the process will exit with code 2\n        if needless disables are found.\n\n      --version, -v\n\n        Show the currently installed version of stylelint.\n  ",
