Span

Gem Version Build Status Code Climate Coverage Status

Calculate the differences between two dates. A few notes:

  • It is calendar-correct, meaning that it respects non-30-day months
  • It currently only calculates the composite span, meaning that each quantity in the result hash contributes to the total span.
  • No external dependencies except the standard library

Installation

Add this line to your application's Gemfile:

gem 'span'

And then execute:

$ bundle

Or install it yourself as:

$ gem install span

Usage

Span ships with a single entry point for its API currently: compute.

require 'span'
end_date = Date.parse '25/03/2013'
start_date = Date.parse '01/01/2012'
result = Span.compute end_date , start_date
puts result[ :year ].inspect  # => 1
puts result[ :month ].inspect # => 2
puts result[ :week ].inspect  # => 3
puts result[ :day ].inspect   # => 4

It returns a Hash that has four Symbol keys: :year, :month, :week, and :day.

TODOs

  • Add more API options
  • Better tests?
  • Clean up code to make it easier to contribute
