class-format/component: false triggers "TypeError: Cannot read property 'test' of undefined"

[gmatheus]

My stylelint config is:

{
  "extends": [
    "stylelint-config-standard",
    "stylelint-rscss/config"
  ],
  "plugins": [
    "stylelint-rscss"
  ],
  "rules": {
    "string-quotes": "single",
    "selector-no-type": true,
    "selector-no-id": true,
    "block-opening-brace-space-before": "never-multi-line",
    "rscss/no-descendant-combinator": true,
    "rscss/class-format": [
      true,
      {
        "component": false
      }
    ]
  }
}

When running using gulp-stylelint, I get this error:

It seems it happens when rscss/class-format -> component rule is set to false.
Is my config file wrong or something?

[rstacruz]

oops! yeah it seems false is not supported here, contrary to what the docs say.

@rstacruz Is there any way to disable the rscss/class-format for components then?
