Minutely

Classes for representing the time of a day by using only hours and minutes.

Installation

Add this line to your Gemfile:

gem 'minutely'

Then execute:

bundle install

Usage

Time

Create a new time:

time1 = Minutely::Time.new(21, 42)
time1.to_s # => "21:42"

time2 = Minutely::Time.new(9, 3)
time2.to_s # => "09:03"

Parse time using DateTime, Time, String or Integer:

Minutely::Time.parse(DateTime.now)
Minutely::Time.parse(Time.now)
Minutely::Time.parse('9:03').to_s # => "09:03"
Minutely::Time.parse(903).to_s # => "09:03"

Get the next minute:

time = Minutely::Time.parse('9:03')
time.succ.to_s # => "9:04"

Compare and sort by times:

time1 = Minutely::Time.parse('9:03')
time2 = Minutely::Time.parse('21:42')

time1 == time2 # => false
time1 < time2 # => true
time1 <= time2 # => true
time1 >= time2 # => false
time1 > time2 # => false

[
  Minutely::Time.parse('21:42'),
  Minutely::Time.parse('9:03'),
  Minutely::Time.parse('15:00')
].sort.map(&:to_s) # => ["09:03", "15:00", "21:42"]

Native Range support:

(Minutely::Time.parse('9:57')..Minutely::Time.parse('10:10'))

Time Range

A special type of time range, that also allows defining ranges spanning over 12 am (0:00).

Create a new time range:

time1 = Minutely::Time.new(9, 3)
time2 = Minutely::Time.new(21, 42)

Minutely::TimeRange.new(time1, time2).to_s # => "09:03-21:42"
Minutely::TimeRange.new(time2, time1).to_s # => "21:42-09:03"

Parse time range using String:

Minutely::TimeRange.parse('9:03-21:42')

Parse time range using Hash:

Minutely::TimeRange.parse(from: '9:03', to: '21:42')

Check whether time range includes time:

range = Minutely::TimeRange.new('9:03', '21:42')

range.include?('10:00') # => true
range.include?('22:00') # => false

Convert to Ruby Range:

Minutely::TimeRange.new('9:03', '21:42').to_r
# => #<Minutely::Time @hour=9, @minute=3>..#<Minutely::Time @hour=21, @minute=42>

Convert to Array of Minutely::Times:

Minutely::TimeRange.new('23:57', '0:03').to_a.map(&:to_s)
# => ["23:57", "23:58", "23:59", "00:00", "00:01", "00:02", "00:03"]

Note this is only possible with ranges not spanning midnight.
