I want to buid up module of Financial variables.
It can be used like this
Financial.year.start #returns start of … guess what
Financial.year.finish
Financial.quarter.start
Financial.quarter.end
…
You got the idea. It must be easily extensible.
Here is what I came up with:
#!/usr/lib/ruby
module FinancialYear
def year
EndPoint.new
end
class EndPoint
def start @start = “01/01/”+Time.now.strftime("%Y")
end
def finish @finish = “31/12/”+Time.now.strftime("%Y")
end
end
end
module Period
def self.included(base)
base.extend(FinancialYear)
end
end
module Financial
include Period
end
I used mostly idioms from Metaprogramming Ruby - Class Extension Mixin
Any suggestion for improvement ?
I am novice in ruby so any suggestion is welcome !

The point of a Class Extension Mixin is that you can use to get both
class methods and instance methods with a single include(). If you
only have class methods, you can also use a simple extend() in the
inclusor.
For something as simple as your example, even that might be overkill.
Unless you have a specific reason to decouple the year() method by
putting it in a separate module, you might be better off just defining
it as a class method of Financial:
class EndPoint
def start @start = “01/01/”+Time.now.strftime(“%Y”)
end
def finish @finish = “31/12/”+Time.now.strftime(“%Y”)
end
end
module Financial
def self.year
EndPoint.new
end
end
