Instance Method Details

#run ⇒ Object

Deletes a manifest from template dir

First it looks in options for the name of the manifest to delete. If this is not set then the user is presented a list of manifests to choose from.

When the manifest specified does not exist a runtime error will be raised

The user will then be prompted with a yes/no prompt to confirm they wish to delete the selected manifest.

If the answer to this is no, the command will stop

Otherwise, the template and manifest will be removed from the template dir

A success message will be presented to confirm to the user that the operation was successful.
