Defined in:
lib/rhc/config.rb

Overview

Responsible for encapsulating the loading and retrieval of OpenShift configuration files and converting them to commandline option equivalents. It also provides the converse option - converting a set of commandline options back into a config file.

In general, the values stored in the config should be identical (require little or no type conversion) to their option form. As new global options are added, only this class should have to change to persist that option.

During normal use, a new Config object should load the appropriate settings and those settings should be converted into commandline option defaults.

TODO: Encapsulate config writing to the home location TODO: Allow the config object to initialized with a path TODO: Remove deprecated methods, remove extra sources.
