# human readable string.
class PlainFormatter
# 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
#
# # displays suggestions in two lines with the leading empty line
# puts formatter.message_for(["methods", "method"])
#
# Did you mean? methods
# method
# # => nil
#
# # displays an empty line
# puts formatter.message_for([])
#
# # => nil
#
def message_for(corrections)
corrections.empty? ? "" : "\nDid you mean? #{corrections.join("\n ")}"
