Public Class Methods

nested_key?(*path) click to toggle source

Checks if a (nested) configuration value is set.

@param path [Array<Symbol>] the configuration key

@example

Wright::Config[:foo] = { bar: :baz }
Wright::Config.nested_key?(:foo, :bar)
# => true

Wright::Config.nested_key?(:this, :doesnt, :exist)
# => false

@return [Bool] true if the configuration value is set and false

otherwise.

  last_key = path.pop
  last_hash = path.reduce(config_hash) do |hash, key|
    return false unless hash.respond_to?(:fetch)
    hash.fetch(key, {})
  end
  last_hash.respond_to?(:key?) && last_hash.key?(last_key)
end
nested_value(*path) click to toggle source

Retrieves a (nested) configuration value.

@param path [Array<Symbol>] the configuration key

@example

Wright::Config[:foo] = { bar: :baz }
Wright::Config.nested_value(:foo, :bar)

# => nil

@return the configuration value or nil if the value is not set
