This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Date.+ (from ruby core) --- d + other -> date --- Returns a date object pointing `other` days after self. The other should be a numeric value. If the other is a fractional number, assumes its precision is at most nanosecond. Date.new(2001,2,3) + 1 #=> #<Date: 2001-02-04 ...> DateTime.new(2001,2,3) + Rational(1,2) #=> #<DateTime: 2001-02-03T12:00:00+00:00 ...> DateTime.new(2001,2,3) + Rational(-1,2) #=> #<DateTime: 2001-02-02T12:00:00+00:00 ...> DateTime.jd(0,12) + DateTime.new(2001,2,3).ajd #=> #<DateTime: 2001-02-03T00:00:00+00:00 ...>
This is MURDOC! A Ruby documentation browser inspired by Smalltalk-80. It allows you to learn about Ruby by browsing through its class hierarchies, and see any of its methods.
