== DESCRIPTION:
|
||||
= Ruby Holidays Gem
|
||||
|
||||
FIX (describe your package)
|
||||
A set of classes to deal with public/statutory holidays in Ruby.
|
||||
|
||||
== FEATURES/PROBLEMS:
|
||||
Extends Ruby's built-in Date class and supports custom holiday definition lists.
|
||||
|
||||
=== Examples
|
||||
|
||||
==== Using the Holidays class
|
||||
|
||||
# Get all holidays on April 25, 2008 in Australia
|
||||
date = Date.civil(2008,4,25)
|
||||
Holidays.by_day(date, :au)
|
||||
=> [{:name => 'ANZAC Day',...}]
|
||||
|
||||
|
||||
# Get all holidays in July, 2008 in Canada and the US
|
||||
from = Date.civil(2008,7,1)
|
||||
to = Date.civil(2008,7,31)
|
||||
Holidays.between(from, to, [:ca,:us])
|
||||
=> [{:name => 'Canada Day',...}
|
||||
{:name => 'Idenpendence Day',...}]
|
||||
|
||||
|
||||
==== Extending Ruby's Date class
|
||||
require 'date'
|
||||
require 'holidays'
|
||||
|
||||
# Lookup Canada Day in the :ca region
|
||||
Date.civil(2008,7,1).is_holiday?(:ca)
|
||||
=> true
|
||||
|
||||
* FIX (list of features or problems)
|
||||
# Lookup Canada Day in the :fr region
|
||||
Date.civil(2008,7,1).is_holiday?(:fr)
|
||||
=> false
|
||||
|
||||
== SYNOPSIS:
|
||||
=== Installation
