Including Rails time helpers in a non-Rails Ruby application

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?

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.
