  def self.logger
    @logger ||= Logger.new(STDOUT)

my requirement is like there are lots of ruby script file i want to put a logger in module and include that in every file than write log in log file it can be warning it can be a info or anything else.

Answer 1

A better alternative would be:

module Logging

def logger
@logger ||= Logger.new(STDOUT)
end

end

And use it like this

class MyLoggingClient
include Logging

#Now you have access to the method `logger` and the instance variable `@logger`.

end
