# frozen_string_literal: true
class Array
##
# Split _string_ into an array. Used in
# conjunction with HighLine's #ask, or #ask_for_array
# methods, which must respond to #parse.
#
# This method allows escaping of whitespace. For example
# the arguments foo bar\ baz will become ['foo', 'bar baz']
#
# === Example
#
# # ask invokes Array#parse
# list = ask 'Favorite cookies:', Array
#
# # or use ask_for_CLASS
# list = ask_for_array 'Favorite cookies: '
#
def self.parse(string)
# Using reverse + lookahead to work around Ruby 1.8's lack of lookbehind
# TODO: simplify now that we don't support Ruby 1.8
string.reverse.split(/\s(?!\\)/).reverse.map { |s| s.reverse.gsub('\\ ', ' ') }
end
