def self.logger(log_level)
  return @logger unless @logger.nil?

  @logger = Logger.new($stderr, progname: File.basename($PROGRAM_NAME), level: log_level)
  @logger.formatter = proc do |severity, _, script_name, message|
    "#{script_name}: #{severity} #{message}\n"
  end
  return @logger
end

Instance Method Details

#fatal(message) ⇒ Object

Another cheap hack to wrap 'logger' above. Called as 'fatal' rather than 'logger.fatal' directly, does the exit for us so we can be lazy.

def fatal(message)
  logger.fatal(message)
  exit 1
end

#logger ⇒ Object

A cheap hack that will instantiate a logger if necessary before sending a log message. This is the normal interface to logging from outside.
