DateInterval

Parse date intervals from strings.

Installation

Add this line to your application's Gemfile:

gem 'date_interval'

And then execute:

$ bundle

Or install it yourself as:

$ gem install date_interval

Usage

You must always define at least one range at the beginning of the expression. The snippet below will return three dates objects.

expr = "2014-01-01 - 2014-01-03"
dates = DateInterval.parse(expr)

You can provide as many intervals as you want. The following expression returns six date objects.

expr = "2014-01-01 - 2014-01-03, 2014-02-01 - 2014-02-03"
dates = DateInterval.parse(expr)

You can also define filters. Filters are applied in sequence, from left to right. The following filters are available:

• none: return no dates. Useful for applying specific filters afterwards.
• [+-]weekends: filter weekend dates
• [+-]weekdays: filter weekdays ()
• [+-]sundays: filter sundays. You can use any weekday name (sundays-saturdays)
• [+-]yyy-mm-dd: add/remove the given date.

Beware that duplicated dates are removed from the final result. They're also sorted.
