ActiveSupport::Duration#human_string

Convert ActiveSupport::Duration objects to human-friendly strings like '2h 30m 17s' or '3y 6m 4d 12h 30m 5s'.

• Like distance_of_time_in_words helper but exact rather than approximate
  • distance_of_time_in_words is somewhat configurable but only gives an approximation ('over 3 years'), with no option to print the exact number of each units.
• Like #inspect but more concise and configurable.
  • #inspect is long ('3 years, 6 months, 4 days, 12 hours, 30 minutes, and 5 seconds') and not at all configurable.
• Like #iso8601 but more human readable rather than machine readable.
  • #iso8601 is concise and machine-readable, but not very human-readable ('P3Y6M4DT12H30M5S')!
• Unlike #to_s, which is very concise ('110839937') but not at all human-readable for large durations

Installation

Add this line to your application's Gemfile:

gem 'activesupport-duration-human_string'

Usage

    duration = 3500.seconds
    duration.human_str                 # =>  '58m 20s'
    duration.human_str(delimiter: '')  # =>  '58m20s'
    duration.human_str(separator: ' ') # =>  '58 m 20 s'
    duration.human_str(delimiter: ', ', separator: ' ') # =>  '58 m, 20 s'

    duration = ActiveSupport::Duration.parse "P3Y6M4DT12H30M5S"
    # => 3 years, 6 months, 4 days, 12 hours, 30 minutes, and 5 seconds

    duration.human_str                  # => "3y 6m 4d 12h 30m 5s"
    (duration - 4.days).human_str       # => "3y 6m 12h 30m 5s"
    duration.human_str(delimiter: ', ') # => "3y, 6m, 4d, 12h, 30m, 5s"

Also aliased as human_string, to_human_s.
