This is just a proof-of-concept gem. Please review the following production-ready suggestions i have for you:
You can use classic Rails time ago in words
time_ago_in_words(Time.now - 60*60*2) + ' ago'
#=> "about 2 hours ago"
# Note that all these returns the same
distance_of_time_in_words(Time.now, 15.seconds.from_now, include_seconds: true)
distance_of_time_in_words(Time.now, 15.seconds.ago, include_seconds: true)
time_ago_in_words(15.seconds.from_now, include_seconds: true)
#=> "less than 20 seconds"
For localization or changing the words to be used, look at this file
Same as before but you will need some explicit requires:
require 'action_view'
require 'action_view/helpers'
include ActionView::Helpers::DateHelper
time_ago_in_words(Time.now - 60*60*2) + ' ago'
#=> "about 2 hours ago"
# If you need to take advantage of Numeric ActiveSupport extensions:
require 'active_support/core_ext/numeric/time'
time_ago_in_words(Time.now - 2.hours) + ' ago'
#=> "about 2 hours ago"
# note that (Time.now - 2.hours) == (2.hours.ago)
If you are programming for the web and don't want to mess your caching strategies then client-side update libraries came to your rescue:
Name | Pure Javascript + Rails integration | jQuery library | jQuery + Rails integration |
---|---|---|---|
37signals Local Time | local_time | smart-time-ago | timeago-rails |
Smart Time Ago | smart-time-ago | timeago-rails | |
Timeago | jquery-timeago | rails-timeago |
If you are looking for results that looks like this
"1 year, 2 months, 4 hours, 5 minutes, and 6 seconds"
There is also time-lord if you want to look around
require 'time-lord'
1.hour.ago.to_i #=> -3600
200.minutes.ago.to_words #=> "3 hours ago"
(200.years + 400.days).ago.to_words #=> "201 years ago"
1.hour.ago.to_range #=> 1379701707..1379705307
If you are working in the opposite direction chronic natural language date parsing to the rescue.
require 'chronic' #gem install chronic
Chronic.parse("1 year from now").year #=> 2014
The Javascript version of chronic is date and can be used within your browser (client-side) or nodejs (server-side).
Humanize elapsed time from some Time instance to Time.now, e.g. '2 hours and 1 minute ago'
This gem provides slightly different approach to the others but still needs some work to be production-ready, check TODO section.
$ gem install time_ago_in_words
or add to your Gemfile this line: gem 'time_ago_in_words'
then run bundle install
Just require 'time_ago_in_words'
and then call Time#ago_in_words method:
require 'time_ago_in_words'
# Comparing from now:
(Time.now - 10).ago_in_words #=> "10 seconds ago"
(Time.now - 1).ago_in_words #=> "1 second ago"
(Time.now - 60).ago_in_words #=> "1 minute ago"
(Time.now - 63).ago_in_words #=> "1 minute and 3 seconds ago"
# This is my current time so you can compare
Time.now #=> 2013-03-06 02:19:23 -0300
Time.local(1981,03,03,20,30,40).ago_in_words #=> "690 days and 5 hours ago"
Time.local(2013,03,03,20,30,40).ago_in_words #=> "2 days and 5 hours ago"
Time.local(2013,03,04,20,30,40).ago_in_words #=> "1 day and 5 hours ago"
Time.local(2013,03,05,20,30,40).ago_in_words #=> "5 hours and 48 minutes ago"
Time.local(2013,03,05,21,13,40).ago_in_words #=> "5 hours and 5 minutes ago"
Time.local(2013,03,06,00,30,40).ago_in_words #=> "1 hour and 48 minutes ago"
Time.local(2013,03,06,01,11,40).ago_in_words #=> "1 hour and 7 minutes ago"
Time.local(2013,03,06,01,27,40).ago_in_words #=> "51 minutes and 43 seconds ago"
Time.local(2013,03,06,02,19,20).ago_in_words #=> "3 seconds ago"
- Fork it.
- Make your feature addition or bug fix and create your feature branch.
- Update the Change Log.
- Add specs/tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, create a new Pull Request.
- Check that your pull request passes the build.
- Add DateTime support. Currently only available for Time objects.
- Add "N months ago"
- Add "N years ago"
- Add "N decades ago"
- Add "N centuries ago"
- Add more rspec Examples
- Implement Time mocking for testing, instead of abusing Time.now on spec
- Extract time_ago_in_words and implement that alternative precision syntax, e.g. "less than a minute ago"
