module Maid::NumericExtensions::Time
From github.com/rails/rails/blob/master/activesupport/lib/active_support/core_ext/numeric/time.rb, with some modifications since `active_support` ruins `Logger` by overriding its functionality.
Public Instance Methods
Reads best without arguments: 10.minutes.ago
# File lib/maid/numeric_extensions.rb, line 64 def ago(time = ::Time.now) time - self end
# File lib/maid/numeric_extensions.rb, line 48 def days self * 24.hours end
# File lib/maid/numeric_extensions.rb, line 58 def fortnights self * 2.weeks end
# File lib/maid/numeric_extensions.rb, line 43 def hours self * 3600 end
# File lib/maid/numeric_extensions.rb, line 38 def minutes self * 60 end
Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.
These methods use Time#advance for precise date calculations when using from_now
, ago, etc. as well as adding or subtracting their results from a Time
object. For example:
# equivalent to Time.now.advance(:months => 1) 1.month.from_now # equivalent to Time.now.advance(:years => 2) 2.years.from_now # equivalent to Time.now.advance(:months => 4, :years => 5) (4.months + 5.years).from_now
While these methods provide precise calculation when used as in the examples above, care should be taken to note that this is not true if the result of `months', `years', etc is converted before use:
# equivalent to 30.days.to_i.from_now 1.month.to_i.from_now # equivalent to 365.25.days.to_f.from_now 1.year.to_f.from_now
In such cases, Ruby's core Date and Time should be used for precision date and time arithmetic
# File lib/maid/numeric_extensions.rb, line 33 def seconds self end
Reads best with argument: 10.minutes.since(time)
# File lib/maid/numeric_extensions.rb, line 72 def since(time = ::Time.now) time + self end
Reads well in a case like:
1.week.since? accessed_at('filename')
# File lib/maid/numeric_extensions.rb, line 88 def since?(other_time) other_time < self.ago end
# File lib/maid/numeric_extensions.rb, line 53 def weeks self * 7.days end
