Including Rails time helpers in a non-Rails Ruby application

activesupport, ruby, ruby-on-rails

Solution

These methods come from ActiveSupport's core extensions (specifically ones on Integer & Numeric), so you can just require them:

require 'active_support/core_ext/integer/time'
require 'active_support/core_ext/numeric/time'

Or if you want all core extensions ActiveSupport provides:

require 'active_support/core_ext'

Or if you want all of ActiveSupport (core extensions included):

require 'active_support/all'

Of course you have to ensure the `activesupport` gem is installed.

Problem

I primarily use Rails to develop in and I love the `1.hour.from_now`, `34.minutes`, and `24.megabytes` helpers that Rails has built into it. However right now I am building just a Ruby application having these helpers would be nice. Is it possible to just get these helpers in a Ruby application without having to bring in the whole Rails framework?
