module Configliere
#
# ConfigBlock lets you use pure ruby to change and define settings. Call
# +#finally+ with a block of code to be run after all other settings are in
# place.
#
# Settings.finally{|c| c.your_mom[:college] = 'went' unless (! c.mom_jokes_allowed) }
#
module ConfigBlock
#
# Define a block of code to run after all other settings are in place.
#
# @param &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.
#
# @example
# 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!
#
def finally &block
self.final_blocks << block if block
end
# 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.
