Duration is an immutable type that represents some amount of time with accuracy in seconds.
A lot of the code and inspirations is borrowed from duration lib, which is a mutable Duration type with lot more features but lack of tests.
I'll try to contact the author of duration to make ruby-duration version 2 of duration's lib. ;)
- Representation of time in weeks, days, hours, minutes and seconds.
- Construtor can receive the amount of time in seconds or a Hash with unit and amount of time.
- Format method to display the time with i18n support.
- Mongoid serialization support. Use
require 'duration/mongoid'. - Tested on mri 1.8.7, ree 1.8.7, mri 1.9.2, jruby and rubinius. Kudos to rvm!
Duration.new(100) => #<Duration: minutes=1, seconds=40, total=100>
Duration.new(:hours => 5, :minutes => 70) => #<Duration: hours=6, minutes=10, total=22200>
Duration.new(:weeks => 3, :days => 1).format("%w %~w and %d %~d") => "3 weeks and 1 day"
Duration.new(:weeks => 1, :days => 20).format("%w %~w and %d %~d") => "3 weeks and 6 days"
iso 8601 more info
Duration.new(:weeks => 1, :days => 20).iso8601 => "P3W6DT0H0M0S"
The current version of this gem supports Mongoid >= 2.1.0. For lower Mongoid versions try the tag v1.0.0
require 'duration/mongoid'
class MyModel
include Mongoid::Document
field :duration, type => Duration
end
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
