Class: NilSection

Inherits:
Object show all
Defined in:
lib/madvertise/ext/config.rb

Overview

A NilSection is returned for all missing/empty values in the config file. This allows for terse code when accessing values that have not been configured by the user.

Consider code like this:

config.server.listen.tap do |listen|
  open_socket(listen.host, listen.port)
end

Given that your server component is optional and does not appear in the configuration file at all, config.server.listen will return a NilSection that does not call the block given to tap _at all_.
