Defines configuration option

When you call option, it defines two methods. One method will take place in the Config class and the other method will take place in the Builder class.

The name parameter will set both builder method and config attribute. If the :as option is defined, the builder method will be the specified option while the config attribute will be the name parameter.

If you want to introduce another level of config DSL you can define builder_class parameter. Builder should take a block as the initializer parameter and respond to function build that returns the value of the config attribute.

Options

  • :as

    Set the builder method that goes inside configure block

  • :default

    The default value in case no option was set

Examples

option :name
option :name, as: :set_name
option :name, default: 'My Name'
option :scopes builder_class: ScopesBuilder
