Instance Method Details

#run ⇒ Object

Prints manifest variables, descriptions and defaults

First it looks to the options for the manifest name. If one is not provided then the user will be prompted to choose a manifest from the list of known manifests.

If the manifest cannot be found a RuntimeError will be raised.

Once the manifest is found, an info table is rendered with the variable names, descriptions and any defined defaults.
