Expose glob options to distinguish files and directories

[Bilge]

Feature Proposal

To facilitate filtering files vs directories, exposing glob options is essential. The underlying glob library has an option called onlyFiles but this is not available via this plug-in. It is not possible to distinguish files and directories using glob patterns alone.

Feature Use Case

glob('*') should be able to match only files, without manually excluding every directory by name. Sometimes it is possible to distinguish files from directories if we can assume files always contain a dot (.) and directories never do (glob('*.*')), but this is not always the case and never guaranteed.
