Instance Method Details

#build_config ⇒ Object

Returns the configuration needed to run the micro related subcommands. First loads saved config from file (if there is any), then overrides loaded values with command line arguments, and finally tries to guess in case neither was used:

vmx       location of micro.vmx file
vmrun     location of vmrun command
password  password for vcap user (in the guest vm)
platform  current platform

#store_config(config) ⇒ Object

Save the cleartext password if –save is supplied. Note: it is due to vix we have to use a cleartext password :( Only if –password is used and not –save is the password deleted from the config file before it is stored to disk.
