Routines to manage the FuzzyDate Class. There is also an extension to the ActiveRecord::Base class to provide an 'acts_as_fuzzy_date' class method. Historical dates are often incomplete or approximate and this class allows such dates to be worked with and stored on a database. construct a new object with FuzzyDate.new( year,month,day,wday,circa) year: optional..is the year number 0 .. big as you like, -ve for BCE month: optional.. is month number 1..12, or nil day: optional.. is day number 1-31 or nil wday: optional.. day of the week - 0=Sunday .. 6=Saturday circa: true = daye is approx, or nil/false note that if you supply the weekday and a year/month/day the system will use your weekday as supplied even if this does not actually correspond in reality to the date supplied. construct a new object with FuzzyDate.parse("date_string") date_string = eg: "tuesday" "12 nov 1012" "circa 412 bc" Use in a database table by storing in an integer field of a format large enough to hold the digits of your maximum year + 8. Eg. a BIGNUM field stores 19 useful characters allowing the year to go to 99,999,999,999. ie 99 billion years. Use with an ActiveRecord class .. require 'fuzzy_date' class HistoricalPerson < ActiveRecord::Base acts_as_fuzzy_date : birth_date, death_date end Copyright (c) Clive Andrews / Reality Bites 2008, 2009, 2010 Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
