Loggable is a gem that's designed to add a logging interface to classes that don't automatically support it.
sudo gem install loggable
Bleeding Edge (hardly):
sudo gem install vigetlabs-loggable --source=http://gems.github.com
Using the Gem is easy, just assign a new logger to your class:
require 'rubygems' require 'logger' require 'loggable' class MyClass; end MyClass.logger = Logger.new('debug.log')
Now, any class or instance methods have access to the logger:
class MyClass def self.do_something logger.debug 'doing something in the class' end def do_something logger.debug 'doing something in an instance' end end
The above code will write into the log file when called:
MyClass.do_something MyClass.new.do_something debug.log: D, [2008-04-24T20:37:32.273930 #25821] DEBUG -- : doing something in the class D, [2008-04-24T20:37:32.274062 #25821] DEBUG -- : doing something in an instance
Removing Logger Functionality
logger= class method to assign a logger to the
class will trigger the methods necessary to start logging messages. If
you want to turn off logging temporarily (without removing the logging
statements from your class), comment out the line where you assign the new
logger. By default, the logger is stubbed out, so any calls to methods on
it will just return nil.
