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 Show archive.org snapshot . 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.
Remark
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
Show archive.org snapshot
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.
