Instance Method Details

#finally(&block) ⇒ Object

Define a block of code to run after all other settings are in place.

Examples:

Settings.finally do |c|
  c.dest_time = (Time.now + 60) if c.username == 'einstein'
  # you can use hash syntax too
  c[:dest_time] = (Time.now + 60) if c[:username] == 'einstein'
end
# ...
# after rest of setup:
Settings.resolve!

Parameters:

  • &block —

    each +finally+ block is called once, in the order it was defined, when the resolve! method is invoked. +config_block+ resolution is guaranteed to run last in the resolve chain, right before validation.

def finally &block
  self.final_blocks << block if block
end

#resolve! ⇒ Object

Processing to reconcile all options

The resolve! for config_block is made to run last of all in the +resolve!+ chain, and runs each +finally+ block in the order it was defined.
