module Aquarium::Utils::OptionsUtils::ClassMethods

add_exclude_options_for(option, options_hash) click to toggle source

Service method that adds a new canonical option and corresponding array with “exclude_” prepended to all values. The new options are added to the input hash.

    # File lib/aquarium/utils/options_utils.rb
196 def add_exclude_options_for option, options_hash
197   all_variants = options_hash[option].dup
198   options_hash["exclude_#{option}"] = all_variants.map {|x| "exclude_#{x}"}
199 end

add_prepositional_option_variants_for(option, options_hash) click to toggle source

Service method that adds a new canonical option and corresponding array with “preposition” prefixes, e.g., “on_”, “for_”, etc. prepended to all values. The new options are added to the input hash.

    # File lib/aquarium/utils/options_utils.rb
