cjheath / datol.cxx

Created July 19, 2012 06:52

Conversion of year/month/day to day since epoch, and back (with weekday)

	#define OFFS -306 /* Offset to epoch-day (Day 1 is 1/1/0001) */
	#define WD 0L /* Day of week offset */

	/*
	* datol: takes a YMD date, and returns the number of days since some base
	* date (in the very distant past).
	*
	* Handy for getting date of x number of days before/after a given date.
	* A date is valid if ltodate() yields the same YMD you started with.

cjheath / reduce_exceptions_helper.rb

Created January 18, 2013 03:07

A spec helper to help you find the origin of all exceptions occurring during your test run (including recovered ones), so you can reduce the abuse of exceptions for control flow. Some surprising facts emerge: a builtin == operator that raises a NoMethodError exception trying to call coerce() on nil... and other wonderful things.

	if ENV["RSPEC_REPORT_EXCEPTIONS"]
	class Exception
	alias_method :old_initialize, :initialize

	def self.exceptions_seen
	@@seen \|\|= {}
	end

	def self.see args
	stack = caller[1..-1]
