Provides an easy way to log a variable value with its label.

Instead of doing

puts "my_var = #{my_var}"


ql :my_var

For Ruby 2+ only.

Additional features

  • display output in reverse video, it's easier to see
  • not limited to variable logging, can log anything that can be converted to a string


  • logging an object attribute: ql :"@user.name"
  • logging a plain string: ql "hello world!"


Add this line to your application's Gemfile:

gem 'quicklog'

And then execute:

$ bundle

Or install it yourself as:

$ gem install quicklog


I wanted the same kind of functionality that the lll gem offers, but with a shorter syntax.

I found the solution I needed in this stackoverflow answer.


  1. Fork it
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create new Pull Request


  • use Awesome Print if available
  • logs through Rails.logger if available
