module Rollbar
# This class provides logger interface that can be used to replace
# the application logger and send all the log messages to Rollbar
#
# Usage:
# require 'rollbar/logger'
# logger = Rollbar::Logger.new
# logger.error('Error processing purchase')
#
# If using Rails, you can extend the Rails logger so messages are logged
# normally and also to Rollbar:
#
# Rails.logger.extend(ActiveSupport::Logger.broadcast(Rollbar::Logger.new))
class Logger < ::Logger
class Error < RuntimeError; end
class DatetimeFormatNotSupported < Error; end
class FormatterNotSupported < Error; end
def initialize

return true if severity < @level
message ||= block_given? ? yield : progname

rollbar.log(rollbar_level(severity), message)
end
