Make your Rails console (and irb) output better readable

On modern Rubies, the IRB's inspection supports syntax highlighting (1.2+) and multi-line output for larger objects (1.3.1+).

You can gem install irb to update your IRB on any Ruby 2.5+.

Pour color on your Rails console with awesome_print. Turn confusing long strings into formatted output. Have objects and classes laid out clearly whenever you need it.

Put gem 'awesome_print', :group => :development into your Gemfile. Now on the Rails console you have the command ap that will give you a colored, formatted output of whatever you pass it. See the example output of the User class below.

For customization visit the repository on Github.



Note that there are other ways to print data in a structured way. Ruby's pretty-print library pp handles formatted printing (you might need to require 'pp'). Pry will give you a readable output, too. If it's already used in your project, you probably won't need to use awesome_print either.

Your development team has a full backlog of feature requests, chores and refactoring coupled with deadlines? We are familiar with that. With our "DevOps as a Service" offering, we support developer teams with infrastructure and operations expertise.
