Defined in:
lib/kinetic/configuration.rb

Overview

Configuration can be set either by passing the set method and or by using the config_file method.

Accessing configuration values by their method accessors will raise Errors::MissingConfigurationValue error. This can be used to ensure that specific values are set at runtime. To access a value without raising an exception use the hash key instead.

Examples:

require 'kinetic'

config_file 'config.yml' # loads the values in config_file into configuration
set :host,  'localhost'  # sets config.host to 'localhost'
config.host   # raises an error if the config host value is not set
config[:host] # returns nil if the host value is not set
