A miniature DSL for describing lengths of time.
Add this line to your application's Gemfile:
gem 'length_of_time'And then execute:
$ bundle
Or install it yourself as:
$ gem install length_of_time
Require the gem:
require 'length_of_time'Use the various methods that we monkey-patch onto Numeric:
# Default unit to return is :seconds
puts 10.minutes # => 600.0
# Can also convert into other units of time
puts 7.days in: :weeks # => 1.0
# Return Floats so that unit conversion does not suffer from Integer division
puts 10.days in: :weeks # => 1.4285714285714286
# Method calls on Numeric literals can be either singular or plural
puts 1.hour # => 3600.0
puts 2.hours # => 7200.0
# When converting into another unit of time, unit must be plural
puts 500.milliseconds in: :minutes # Correct
puts 750.milliseconds in: :minute # Incorrect - will give an error
# Full list of units supported:
# Singular [:millisecond, :second, :minute, :hour, :day, :week, :fortnight]
# Plural [:milliseconds, :seconds, :minutes, :hours, :days, :weeks, :fortnights] After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
