Instance Method Details

#run ⇒ Object

Opens a manifest in the chosen editor program

First it looks to the options for the manifest name. If this is not provided the user will be given a list to select from.

The manager then attempts to find the manifest by name. If it cannot be found, a RuntimeError is raised and the command stops.

Otherwise a new editor subprocess is started with the manifest path given as an arg.

This process will wait until the conclusion of the editor process. It’s recommended that the editor be a command line editor like ‘vi`
