Best way to pretty print a hash
require 'pp'pp my_hashUse pp if you need a built-in solution and just want reasonable line breaks.
Use awesome_print if you can install a gem. (Depending on your users, you may wish to use the index:false option to turn off displaying array indices.)
If you have JSON, I recommend JSON.pretty_generate(hash) because it is simpler than awesome_print, looks great in a pre tag, and allows for easy copying from a web page. (See also: How can I "pretty" format my JSON output in Ruby on Rails?)
Another solution which works better for me than pp or awesome_print:
require 'pry' # must install the gem... but you ALWAYS want pry installed anywaysPry::ColorPrinter.pp(obj)
