# Beloved squiggly heredocs did not exist in Ruby 2.1, which we still want to
# support, so let's give kudos with a method `sq`.
module Squiggle
# Outdents each line on a multiline string by the number of leading
# whitespace characters on the first line.
#
# This method exists so we can unindet heredoc strings the same way that
# Ruby 2.2's squiggly heredocs work, but still support Ruby 2.1 for the
# time being.
#
# For example:
#
# str = sq(<<-str)
# This multiline string will be outdented by two characters,
# so the extra indentation on this line will be kept,
# while this line sits on the same level as the first line.
# str
def sq(str)
width = str =~ /( *)\S/ && $1.size
str.lines.map { |line| line.gsub(/^ {#{width}}/, '') }.join
end
