How replicate rails console output style in runner script?

Question

When running User.first in the rails console I will get a beautiful output, something like:

I assume this is taken care of by pry. How can I get the same output styling when using the runner? Consider a file tinker.rb

u = User.first
puts u

and running it like: rails r './tinker.rb. While it will output something, it is not as polished as in the console:

#<User:0x00007fc6518acec8>

How can I make it exactly the same?

Answer 1

This formatting is a result of PrettyPrint module - PP:

u = User.first
pp u #=> Which is basically a shortcut for: PP.pp(u)

Note however, that by default this will not generate a colourful output. Pry additionally process the formatted string through another gem - coderay, which is responsible for ruby syntax highlighting. If you want to print in colour, then:

u = User.first
Pry::ColorPrinter.pp(u)
