Shorten the error message in the terminal

Rails error messages in the terminal are too long and contain often useless information. Is there a gem / solution to reduce rail error messages? Example:

2.2.2 :012 >   puts 1.red

What am I getting right now:

NoMethodError: undefined method `red' for 1:Fixnum

What I want: (optional red)

NoMethodError: undefined method `red' for 1:Fixnum
===>Long error message saved in e. Get full messages with 'puts e'

Is it possible?

You can try the better_errors gem . It also provides a better explanation of errors through the browser.

This is the link to the github repository

EDIT

If you are also looking for a custom console (also exception tracing), try to see pry
