p() vs. puts() vs. print() in Rails

Use p.

Rails has three printing methods, two are common, one is less so.

  1. print prints the string (to_s) version of what is passed to it.
  • puts works like print but adds a newline \n.
  • p prints the .inspect version of what is passed to it, along with the trailing newline.

Personally, i type some form of:

puts some_object.inspect

multiple times a day. No more. This statement functions identically to:

p some_object

11 characters less, and typos are nearly impossible. Type less, code more.
