module DidYouMean
# The +DidYouMean::VerboseFormatter+ uses extra empty lines to make the
# suggestion stand out more in the error message.
#
# In order to activate the verbose formatter,
#
# @example
#
# OBject
# # => NameError: uninitialized constant OBject
# # Did you mean? Object
#
# require 'did_you_mean/verbose'
#
# OBject
# # => NameError: uninitialized constant OBject
# #
# # Did you mean? Object

#
class VerboseFormatter
# Returns a human readable string that contains +corrections+. This
# formatter is designed to be less verbose to not take too much screen
# space while being helpful enough to the user.
#
# @example
#
# formatter = DidYouMean::PlainFormatter.new
#
# puts formatter.message_for(["methods", "method"])
#
#
# Did you mean? methods
# method
#
# # => nil
#
