def read
  path = File.join('./', @config[:path][:routes])
  raw_content = File.read(path)

  raw_content.gsub!(/\\\s*\n+\s*->/, '->')
  raw_content.gsub!(/\\\s*\n+\s*=>/, '=>')
  raw_content.gsub!(/\\\s*\n+\s*=\*/, '=>')


  # use '^' instead spaces and tabs
  raw_content = raw_content.gsub(/\t/, '  ')
                  .gsub('  ', '^')
                  .gsub(' ', '')

  ###Hack:
  # grammar problem - can't simply match '-' character in route path when '->' present.
  # Will be resolved later. Replace '->', '<-' with '*>', '<*' for a while for syntax parser.
  ###
  raw_content = raw_content.gsub('->', '*>').gsub('<-', '<*')

  raw_content.gsub("\n", ';') + ';'
