heroku_config_parser.rb

# Parses configuration out from the "heroku config" command, and converts to command-line input 
# for the "heroku config:add" command. It escapes $ characters.

  config_line_regex = /([^:]+):(.*)/
  config_text.split("\n").map do |line|
    line_match = line.match(config_line_regex)
    [line_match[1], line_match[2]]
  end.map do |name, value|
    "#{name.strip}=\"#{value.strip.gsub("$", "\\$")}\""
  end.join(" ")
