Add logger to module/class

Ruby
#1

I want a dual logger so I have sub-classed Logger with this :
class Logging < Logger
def initialize(file, stdout=false)
@log_file = Logger(file)
@log_out = Logger(stdout) if stdout
end
#Override the logger’s methods to write to both stdout and file if
needed
end

How would I implement a global logger for the module and the main. The
logger would be initiated within the main and I’d want to pass it to the
module with the same parameters, given a module like this :

module A
def self.a
end

Anywhere inside the module I want to be able to do logger.info(str)

and it will log to same logger as initialized in main.
class c
def ca
end
end
end

Take a look at the “Logging” gem as it already support logging to
multiple destinations. The interface for logger objects is the same as
the core Ruby logger class.

One trick you can use with the Logging framework is this

require ‘logging’
include Logging.globally

This will add a “logger” method to Object which will be inherited by
every object in your application. This will allow you to do call
“logger.info” within your module or any other class.
