Small wrapper around the default ruby Logger class to contain a couple of conventions and conveniences assembled over the years including:

  • exception logging together with their callstacks
  • easily parsable timestamps
  • easily log level marker

To experiment with that code, run bin/console for an interactive prompt.


Add this line to your application's Gemfile:

gem 'ac-logger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ac-logger


require 'ac/logger'

get a logger instance, for example at top of your class, and log away:

class A
    Log = AC::Logger['/var/log/foo.log']

    def somefunc
        Log.debug "bla bla bla.."
    rescue => e
        Log.ex(e, "just a demo, relax")


After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
