Instance Method Details

#cached_run? ⇒ Boolean

RuboCop caches results by taking a hash of the file contents & path, among other things. It disables its cache when working on file-content from stdin. Unfortunately we always use RuboCop’s stdin, even when we’re linting a file on-disk. So, override RuboCop::Runner#cached_run? so that it’ll allow caching results, so long as haml-lint itself isn’t being invoked with files on stdin.

Returns:

  • (Boolean)
