Constructor Details

#initialize(opts) ⇒ Runner

Accepts a Hash of options passed from the parsed command line. Currently there is only one option, :list, which is treated as a boolean, and determines whether the branches will simply be listed non-interactively (list: true), or interactively with opportunities for the user to select branches for deletion (list: false).

Instance Method Details

#run(args) ⇒ Object

Runs the application, listing branches either interactively or non-interactively. Returns an exit status, suitable for passing to ‘exit()`. `args` should be passed an array of non-option/non-flag arguments received from the command line. If this array is of inappropriate length, EXIT_FAILURE will be returned. (The appropriate length may be 0.)
